[Rationale for choosing an antibiotic for the treatment of cystitis: recommendations of clinical pharmacologists: A review].
    Terapevticheskii arkhiv, 2022, Oct-12, Volume: 94, Issue:8

    In recent years, the harmonization of domestic and foreign clinical recommendations for the treatment of cystitis has been achieved. Nitrofurans and fosfomycin trometamol are recommended as first line therapy antibiotics, and oral 3rd generation of cephalosporins are recommended as alternative antibiotics; fluoroquinolones are excluded from the recommended medications due to an unfavorable safety profile. The main rationale for inclusion of antibiotics in the recommendations as a first line therapy of cystitis is the level of resistance of uropathogens to antibiotics, primarily Escherichia coli. Stable low level of resistance of E. coli in Russia was noted to nitrofurans and fosfomycin (5%), higher to cephalosporins. Among nitrofurans, furazidine is characterized by higher activity against E. coli compared to nitrofurantoin. The potassium salt of furazidine in dosage form with magnesium carbonate is preferred, since it is characterized by higher bioavailability and provides a therapeutic level of concentrations in urine above the MIC during the entire dosing period. Due to the global increase in the resistance of uropathogens observed in recent years, experts have begun to pay more and more attention to the ecological safety of antimicrobial therapy in order to minimize the risk of concomitant (collateral) damage, contributing to the selection of multi-drug resistant strains of microorganisms. In the latest WHO document of 2021, experts divided antibiotics into three groups (ACCESS, WATCH, RESERVE) according to the priority of choice. The ACCESS group of drugs for the treatment of cystitis includes nitrofurantoin and furazidine as agents with minimal collateral effect, while fosfomycin trometamol and cephalosporins are listed in the WATCH group. Thus, from the standpoint of ecological safety, WHO experts recommend prescribing nitrofurans in the treatment of cystitis in the first line of therapy.. В последние годы достигнута гармонизация отечественных и зарубежных клинических рекомендаций по лечению цистита. В качестве средств 1-й линии рекомендованы нитрофураны и фосфомицина трометамол, в качестве альтернативных препаратов пероральные цефалоспорины III поколения. Фторхинолоны исключены из рекомендованных средств из-за неблагоприятного профиля переносимости. Основным обоснованием включения в рекомендации в качестве средств 1-й линии терапии служит уровень устойчивости уропатогенов, прежде всего ведущего Escherichia coli к антибиотикам. Стабильно низкая устойчивость E. coli в Российской Федерации отмечена к нитрофуранам и фосфомицину (5%), более высокая к цефалоспоринам. Среди нитрофуранов фуразидин характеризуется более высокой активностью против E. coli по сравнению с нитрофурантоином. Калиевая соль фуразидина в лекарственной форме с магния карбонатом основным является предпочтительной, поскольку характеризуется более высокой биодоступностью и обеспечивает терапевтический уровень концентраций в моче выше минимальной подавляющей концентрации в течение всего периода дозирования. В связи с глобальным ростом устойчивости уропатогенов, наблюдаемым в последние годы, эксперты стали обращать все больше внимания на экологическую безопасность антимикробной терапии с целью минимизации риска развития сопутствующего (параллельного) ущерба терапии, способствующего селекции полирезистентных штаммов микроорганизмов. В последнем документе Всемирной организации здравоохранения (ВОЗ) от 2021 г. эксперты разделили антибиотики на 3 группы (ACCESS, WATCH, RESERVE) по приоритету выбора. Из препаратов для лечения цистита в группу ACCESS включены нитрофурантоин и фуразидин как средства с минимальным сопутствующим эффектом, а фосфомицина трометамол и цефалоспорины указаны в группе WATCH. Таким образом, с позиции экологической безопасности при лечении цистита эксперты ВОЗ рекомендуют в 1-й линии терапии назначать нитрофураны.

[Rationale for the choice of an antibiotic for urinary tract infections with an emphasis on the environmental safety of therapy].
    Urologiia (Moscow, Russia : 1999), 2021, Issue:4

    Difficulties in prescribing antibiotics for lower urinary tract infections (UTI) are associated with a fact that such patients can be treated not only by urologists, but also by general practitioners, internists, pediatricians, and gynecologists. Therefore, it is important to adapt the practical recommendations for the treatment of cystitis for different medical disciplines. When creating clinical guidelines, experts take into account the different factors in choosing antibiotic therapy. First of all, pharmacokinetics is of importance and drugs with renal excretion should be preferred. Secondly, the natural activity of the antibiotic against the pathogens, which cause cystitis, has to be considered. In uncomplicated infections, E. coli predominates, while in complicated and recurrent infections E. coli and other enterobacteria are commonly isolated, as well as Enterococci. In addition, local resistance pattern is reviewed. In the Russian Federation E. coli has minimal resistance to nitrofurans and fosfomycin. Lastly, antibiotics can negatively affect the gastrointestinal and urinary tract microbiota and contribute to the increase of antibiotic resistance and the selection of antibiotic-resistant strains, therefore the environmental safety of therapy should be considered. The effect of antibiotics on the resident flora of the gastrointestinal tract, urinary tract and vagina is called collateral effect, or concomitant (parallel) damage, and it may exceed the therapeutic effect of some antibiotics. Cephalosporins and fluoroquinolones can cause ecologically unfavorable effects with the risk of selection of resistant strains; therefore, these drugs are currently considered as second-line agents for UTI. When choosing an antibiotic, preference should be given to drugs with the narrow spectrum and minimal collateral damage, i.e., the principle of "minimum sufficiency" is of importance. Nitrofurans and fosfomycin trometamol are the optimal drugs in terms of efficiency and environmental safety in UTI. WHO experts consider nitrofurans as the most environmentally safe antibiotics with a minimally sufficient spectrum of activity. The environmental safety of antimicrobial therapy is an important component of preventing antibiotic resistance at the global and local levels.

The comeback of trimethoprim in France.
    Medecine et maladies infectieuses, 2017, Volume: 47, Issue:4

    Already used in various countries, trimethoprim (TMP) was withdrawn from the French market in 1990, but should be soon available again. This article reviews the experience of TMP use around the world and its current use in Europe. Label use and guidelines only recommend the use of TMP for the treatment of urinary tract infections (UTI). Compared with co-trimoxazole (Co-T), a combination of TMP and sulfamethoxazole (SMX), TMP has (a) a similar resistance rate among Escherichia coli strains (estimated between 10 and 20% in uncomplicated cystitis), (b) a similar clinical efficacy for cystitis prevention and treatment, (c) a lower toxicity (as severe toxicity adverse effects of Co-T come from its sulfonamide component), (d) limited data for the treatment of pyelonephritis and male UTIs, and (e) an important impact on the microbiota. TMP should thus be indicated in the third-line empirical treatment of acute uncomplicated cystitis (sparing fluoroquinolones and nitrofurantoin), in the prevention of recurrent acute cystitis when an antibiotic prophylaxis is required (possibly in first line), and in the treatment of documented acute cystitis at risk of complications. Updated data on the epidemiology of resistance to TMP per clinical pictures is now required. The bactericidal effect of TMP should also be confirmed on recent strains (although limited recent data suggests a bactericidia similar to that of Co-T) and its clinical efficacy should be evaluated in pyelonephritis and male UTI.

Acute uncomplicated cystitis in women. The essentials of first-line management.
    Prescrire international, 2015, Volume: 24, Issue:156

    In the absence of fever and low back pain, there is a high probability that a female patient has acute uncomplicated cystitis if she reports dysuria' and urinary frequency but no vaginal discharge or pruritus. The antibiotic therapy of choice for an episode of acute uncomplicated cystitis is a single oral dose of fosfomycin trometamol. In patients with recurrent infections, the strategy that results in the lowest antibiotic exposure without impairing efficacy is to treat each episode as soon as the first clinical symptoms appear.

Recurrent uncomplicated cystitis in women: allowing patients to self-initiate antibiotic therapy.
    Prescrire international, 2014, Volume: 23, Issue:146

    Acute uncomplicated cystitis is a lower urinary tract infection occurring in the absence of anatomic or functional abnormalities of the urinary tract or any other complicating factors.The organism responsible is often an enterobacterium, especially Escherichia coli. What is the role of antibiotic therapy for non-pregnant women with recurrent acute uncomplicated cystitis? We reviewed the available evidence using the standard Prescrire methodology. A single oral dose of fosfomycin trometamol is the antibiotic of choice for treating an episode of acute uncomplicated cystitis. Alternative antibiotics are certain fluoroquinolones or co-trimoxazole (a fixed-dose combination of sulfamethoxazole and trimethoprim). For recurrent acute uncomplicated cystitis, cranberry juice has modest efficacy in reducing the frequency of episodes. A number of non-drug measures are typically proposed, although their effects are unproven: drinking sufficient fluids and urinating regularly; urinating after sexual intercourse; and avoiding spermicides. The strategy that results in the lowest antibiotic exposure is a short course of antibiotics for each episode of urinary tract infection, initiated as soon as clinical symptoms appear. Long-term antibiotic therapy is sometimes offered. According to one systematic review, women taking long-term prophylactic antibiotic therapy had about 6 times fewer clinical recurrences than with placebo. According to one randomised trial, 3 g of fosfomycin trometamol taken as a single dose every ten days reduced the frequency of recurrence, resulting in 0.14 episodes of infection per year on average versus about 3 episodes with placebo (p < 0.001). The amount of antibiotic used when fosfomycin trometamol is taken every 10 days for 6 months is equivalent to treatment of 18 acute episodes of cystitis. When cystitis appears to be associated with sexual intercourse, two small randomised trials suggest that routine postcoital antibiotic treatment is more effective than placebo and as effective as long-term antibiotic therapy. Adverse effects, some of which can be serious, depend on the antibiotic used. The development of resistance among enterobacteria is one argument for limiting the use of antibiotics, in order to preserve their efficacy in serious infections. In practice, the strategy that uses the fewest antibiotics is to treat each episode as soon as the first clinical symptoms appear. Cases in which the frequency of recurrence warrants regular antibio

[Antibacterial therapy for acute cystitis in the age of growing pathogen resistance].
    Terapevticheskii arkhiv, 2014, Volume: 86, Issue:4

    Acute cystitis refers to uncomplicated lower urinary tract infections, with the recurrence rates after the first cystitis episode being 50%. The basic treatment for the above diseases is antibacterial therapy, whose efficiency depends entirely on the right choice of a drug during initial empiric therapy. The paper gives the European Association of Urology guidelines and Russian guidelines, which are based on the results of both international (ARESC) and Russian (DARMIS) studies of urinary tract infection pathogens and their susceptibility to antibacterial drugs. Phosphomycin trometamol and furasidine potassium are the drugs of choice to treat acute cystitis in Russia now.

Fosfomycin versus other antibiotics for the treatment of cystitis: a meta-analysis of randomized controlled trials.
    The Journal of antimicrobial chemotherapy, 2010, Volume: 65, Issue:9

    Cystitis is a common infection. The alarmingly high resistance rates exhibited by contemporary uropathogens necessitate the re-evaluation of old antibiotics.. To evaluate the effectiveness and safety of fosfomycin compared with other antibiotics for the treatment of patients with cystitis.. We performed a meta-analysis of randomized controlled trials (RCTs), generated from searches performed in PubMed, Scopus and Cochrane CENTRAL, which involved patients with cystitis treated with fosfomycin versus other antibiotics.. Twenty-seven trials (eight double-blind) were included. Sixteen of these 27 trials involved exclusively non-pregnant female patients, 3 involved adult mixed populations of older age, 5 involved pregnant patients and 3 involved paediatric patients. Regarding clinical success, no difference was found in the comprehensive analysis regarding all comparators combined [10 RCTs, 1657 patients, risk ratio (RR) = 1.00, 95% confidence interval (CI) = 0.98-1.03] in trials involving non-pregnant females and in trials involving mixed populations. Insufficient relevant data were provided from trials involving paediatric and pregnant patients. No difference between fosfomycin and comparators was also found in all comparisons regarding the remaining effectiveness outcomes (namely microbiological success/relapse/re-infection). Fosfomycin had a comparable safety profile with the evaluated comparators in non-pregnant women, mixed and paediatric populations, whereas it was associated with significantly fewer adverse events in pregnant women (4 RCTs, 507 patients, RR = 0.35, 95% CI = 0.12-0.97).. In the era of high drug resistance rates, reported even among community-acquired uropathogens, fosfomycin may provide a valuable alternative option for the treatment of cystitis in non-pregnant and pregnant women and in elderly and paediatric patients.

[Treatment of uncomplicated lower urinary tract infections].
    Enfermedades infecciosas y microbiologia clinica, 2005, Volume: 23 Suppl 4

    Empirical antibiotic treatment of lower urinary tract infections should be based on the patient's clinical data and on local sensitivity data. Because of the increase in resistance among uropathogens, recommendations on the empirical treatment of urinary tract infections have been modified. Currently, the empirical use of co-trimoxazole, ampicillin, and first-generation cephalosporins and quinolones is not recommended. Fluoroquinolones have been demonstrated to be highly effective in comparative studies but, because of the increase in resistance, the type of patient who can benefit from these antimicrobial agents must be selected. Second- and third-generation cephalosporins still have high sensitivity rates, although the higher recurrence rates associated with their use and the emergence of extended-spectrum beta-lactamase-producing enterobacterial in the community should be taken into account. Amoxicillin-clavulanate is less effective in eradicating infections than quinolones. Fosfomycin-trometamol has resistance rates of below 2% and single-dose therapy has been demonstrated to be safe and effective. Nitrofurantoin is also currently active, although it must be administered for 7 days and can produce toxicity. Both agents are currently recommended as alternative therapeutic options to fluoroquinolones in uncomplicated infections of the lower urinary tract.

[Choice of antibiotics in uncomplicated cystitis; application of 'system of objectified judgement analysis' (SOJA) method].
    Nederlands tijdschrift voor geneeskunde, 1999, Dec-04, Volume: 143, Issue:49

    To determine the drug of choice for the treatment of uncomplicated cystitis.. Drug selection was performed by means of the so-called 'system of objectified judgement analysis' (SOJA) method by a working group of 11 persons. The following selection criteria were used: pharmacokinetics, interactions, probability of hitting (the probability that the microorganism is sensitive to the antibiotic), development of resistance, specific use in urinary tract infections, efficacy, side effects, dosage-frequency, duration of treatment, cost and documentation. The following drugs were included in the study: amoxicillin (with or without clavulanic acid), nitrofurantoin, sulfamethizole, trimethoprim, co-trimoxazole, ciprofloxacin, norfloxacin, ofloxacin and fosfomycin trometamol.. Fosfomycin and nitrofurantoin slow release showed the highest scores. The main selection criteria that determined the selection of a drug were especially specific use in urinary tract infections, development of resistance, probability of hitting and cost.. Fosfomycin and nitrofurantoin slow release best fulfill the requirements for drugs in the treatment of uncomplicated cystitis. No comparative studies have been performed with the 3-day treatment of uncomplicated cystitis with nitrofurantoin slow release or with trimethoprim. Fluoroquinolones play no important part in the treatment of uncomplicated cystitis, mainly because of the risk of development of resistance.

Single-dose treatment of acute cystitis with fosfomycin tromethamine.
    The Annals of pharmacotherapy, 1998, Volume: 32, Issue:2

    To review the clinical pharmacology of fosfomycin tromethamine, a new antimicrobial agent for the treatment of uncomplicated lower urinary tract infections (UTIs).. Publications in English on fosfomycin, fosfomycin tromethamine, and fosfomycin trometamol (MEDLINE, 1970-1997), as well as unpublished studies submitted to the Food and Drug Administration (FDA), were reviewed.. Comparative, randomized, controlled studies were used to analyze the efficacy and safety of fosfomycin tromethamine.. Fosfomycin tromethamine is an oral antimicrobial indicated for the treatment of uncomplicated lower UTIs. This agent is active in the urine against common uropathogens that are associated with cystitis in women, including organisms resistant to other antibiotics. A single dose of fosfomycin tromethamine is well absorbed and produces therapeutic concentrations in the urine for 2-4 days. Comparative clinical trials suggest that a single dose of fosfomycin tromethamine 3.0 g is as clinically effective as 7- to 10-day treatment regimens of standard agents used to treat UTIs, such as nitrofurantoin, norfloxacin, and trimethoprim/sulfamethoxazole. Fosfomycin tromethamine is well tolerated and appears safe to use during pregnancy.. Fosfomycin tromethamine is the only antimicrobial to be approved by the FDA for single-dose therapy in women with acute cystitis. It is as effective and safe as multidose comparators and appears safe to use during pregnancy. The acquisition cost of this new drug will need to be weighed against the improved compliance and convenience associated with its use in the treatment of uncomplicated UTIs.

    Bearberry (. The objective of the study is to assess the safety and non-inferiority of bearberry as an alternative therapy in the treatment of acute uncomplicated cystitis in comparison with standard antibiotic therapy (fosfomycin).. This is a randomised controlled double-blinded multicentre trial. Eligible patients will be premenopausal women with a sum score of ≥6 for the typical acute uncomplicated cystitis symptoms (frequency, urgency, painful urination, incomplete emptying, suprapubic pain and visible haematuria) reported on the Acute Cystitis Symptom Score (ACSS) typical domain and pyuria. Patients will be randomly assigned to receive 3 g single dose of fosfomycin powder and two placebo tablets three times a day for 7 days or B a single dose of placebo powder and two tablets containing a dry extract of Uvae ursi folium. At least 504 patients (allocated as 1:1) will need to be enrolled to access non-inferiority with a non-inferiority limit of 14% for the primary endpoint.Improvement of symptoms of uncomplicated cystitis (based on the ACSS score) at day 7 is defined as the primary endpoint, whereas several secondary endpoints such as the number and ratio of patients with bacteriuria at day 7, frequency and severity of side effects; recurrence of urinary tract infection, concurrent use of other over the counter (OTC) medications and food supplements will be determined to elucidate more detailed differences between the groups. The number of recurrences and medications taken for treatment will be monitored for a follow-up period of 90 days (80-100 days).. This study has been approved by the Scientific and Research Ethics Committee of the Hungarian Medical Research Council (IV/4225-1/2021/EKU). The results will be disseminated by publication of peer-reviewed manuscripts.. NCT05055544.

[The efficiency of combined regimens for the treatment of urinary tract infections in women using the herbal drug Canephron N].
    Urologiia (Moscow, Russia : 1999), 2021, Issue:6

    Currently, empiric antibiotic therapy is considered the standard for acute cystitis. However, additional treatment may be required to alleviate the patient's condition and shorten the time to subjective recovery.. To evaluate the efficiency of the combined administration of fosfomycin trometamol and herbal drug Canephron N in comparison with a single oral dose of fosfomycin trometamol in women with uncomplicated bacterial cystitis.. A randomized, comparative, open-label study was carried put between January 2018 and June 2019. The study included 112 women with symptoms of acute uncomplicated cystitis, who were randomized between two groups in a 1:1 ratio. In the main group, patients received a single oral dose of fosfomycin in combination with Canephron N (2 tablets t.i.d. for 2 weeks), while in the control group patients received only a single dose of fosfomycin (3 g). Symptoms were assessed using the Russian version of the Acute Cystitis Symptom Score (ACSS), completed daily for a week. Also, all patients underwent urine analysis on the 1st, 3rd, 5th and 7th days of therapy. The mean time to complete recovery based on the ACSS questionnaire and the time to resolution of pyuria were compared using the Mann-Whitney U test. Comparison of the proportion of patients with complete cure, according to the questionnaire, or with the elimination of pyuria was carried out using the chi-square test.. The final analysis included 46 patients who received fosfomycin in combination with Canephron and 47 patients who received fosfomycin as monotherapy. In the group of combination therapy, patient-reported complete recovery (assessed by the ACSS questionnaire) was seen on average after 1 day, while in patients treated with monotherapy, the median time to subjective recovery was 3 days (p=0.00012). A significant difference between the groups in the proportion of patients with complete resolution of symptoms of acute cystitis was observed on days 1, 2, and 3 (p<0.05). The therapy was well tolerated in both groups. The most frequent adverse events were dyspepsia (8.7% in the combination group compared to 6.4% in the control group) and headache (in 4.3% and 6.4% of patients, respectively).. the combined use of fosfomycin trometamol and the herbal drug Canephron N allows to reduce the duration of symptoms in patients with acute cystitis, thereby accelerating return to their usual lifestyle patterns.

[Phenazopyridine and fosfomycin for the acute cystitis treatment: results of multicenter randomized study].
    Urologiia (Moscow, Russia : 1999), 2021, Issue:3

    To evaluate the analgesic effect, efficacy and tolerability of phenazopyridine in combination with fosfomycin for the treatment of acute uncomplicated cystitis in working-age female.. A total of 152 women with acute uncomplicated cystitis were included in multicenter, randomized, open-label study which were carried out in 5 polyclinics of the Perm Territory. All the patients were divided into 2 groups of 76 people each, depending on the treatment. In the main group, women received oral phenazopyridine 200 mg 3 times a day for 2 days (a total dose 1200 mg) and fosfomycin trometamol in a dose of 3 g once. In the control group, patients received a single dose of fosfomycin trometamol (3 g) and drotaverin 80 mg 3 times a day for 2 days. A visual analogue scale (VAS) was used for evaluation of pain intensity. The symptoms of cystitis were assessed using the ACSS scale. In addition, urinalysis, urine culture and other methods were done. The results were evaluated after 6, 12, 24, 48 hours, 3 and 6 days.. In the main group, the severity of pain according to the VAS decreased from the initial 7.2+/-0.5 points to 1.6+/-0.2 points after 12 hours, to 0.4 +/- 0.05 points after 24 hours. Pain syndrome completely disappeared in all patients after 48 hours. In the control group, at all time points, a significant less pronounced analgesic effect was seen (p<0.001). The overall ACSS score in the main group decreased from the 12.0+/-0.5 points to 2.1+/-0.3 after 3 days and to 0.28+/-0.04 points after 6 days (p<0.001), which indicated a more rapid resolution of symptoms compared to the control group. The symptomatic effect of phenazopyridine (relief of pain, dysuria and discomfort) provided a more pronounced improvement in the well-being in the main group in comparison to the control group, which was confirmed by Dynamics domain of the ACSS scale (p<0.001). The combination of fosfomycin and phenazopyridine was more effective than the combination of fosfomycin and drotaverine. The clinical and microbiological cure rate in the main group was 97.4% and 96.9%, respectively. Leukocyturia was resolved earlier, and the duration of treatment decreased by 30.1%. An undesirable effect of phenazopyridine (nausea) was detected only in 1 (1.3%) patient.. Phenazopyridine has a pronounced analgesic effect and is proved to be an effective and safe drug in patients with acute uncomplicated cystitis.

[The effectiveness of complex phytotherapeutic medications in the management of uncomplicated lower urinary tract infections in women].
    Urologiia (Moscow, Russia : 1999), 2018, Issue:4

    Lower urinary tract infections (LUTI) are the most common urological diseases. Fosfomycin is one of the antibiotic agents with proven efficacy that are most frequently used to treat UTIs. Despite the high effectiveness of antibiotic therapy with this drug, in some patients, the LUTIs persist or recur. It is advisable to prevent the development of recurrent infections using herbal preparations. The study aimed to evaluate the effectiveness of integrated treatment of women with acute uncomplicated cystitis using the plant-based medication Phytolysin.. The study comprised 63 women with acute uncomplicated cystitis, who were randomly assigned to two groups. The women in the control group (n = 31) received a single 3-g dose of fosfomycin. In the study group (n = 32), women received a single 3-g dose of fosfomycin and Phytolysin according to the manufacturers instructions three times daily for a month. The examination was performed on admission and on days 3, and 7, and included daily filling out voiding diaries, a 5-point verbal assessment of pain, urinalysis and urine culture. During the next three months, cases of recurrence were registered, and bacteriological analysis of urine was conducted.. On admission, all patients complained of pain in the projection of the urinary bladder, frequent urination in small portions, and a sensation of urethral discomfort. All women had leukocyturia and bacteriuria. By the 3-rd day after taking fosfomycin, both groups showed similar improvement in the clinical manifestations of the disease. All urine cultures were negative. By the 7th day after the initiation of therapy, the patients in the study group had normal laboratory parameters and no clinical manifestation of LUTI, while in the control group leukocyturia (p <0.05) persisted. During a 3-month follow-up, recurrence of LUTI was observed in 6 (19.4%) and 3 (9.4%) patients in the control and study group, respectively. Also, bacteriological studies of urine showed the same pathogen as on admission in 5 (16.1%) and 1 (3.2%) patients of the control and study group, respectively.. Phytolysin can be recommended for use in the integrated management of acute uncomplicated cystitis, as well as a means of preventing recurrences of this disease.

Clinical effects of 2 days of treatment by fosfomycin calcium for acute uncomplicated cystitis in women.
    Journal of infection and chemotherapy : official journal of the Japan Society of Chemotherapy, 2011, Volume: 17, Issue:1

    Fosfomycin calcium is a fosfomycin antimicrobial agent with a characteristic structure. After oral administration, the drug is absorbed and excreted via the kidneys in the unchanged form, without being metabolized in the body. It is, therefore, indicated for the treatment of urinary tract diseases, including cystitis and pyelonephritis. In the present study, the clinical usefulness of fosfomycin calcium (FOSMICIN® TABLETS 500) administered orally at the dosage of 1 g (two tablets) three times daily for 2 days was examined in female patients, who were at least 20 years of age, with acute uncomplicated cystitis of bacterial origin. Of the 48 patients enrolled between February 2008 and August 2008, 39 were evaluable for efficacy and safety. Overall evaluation of the cure revealed that microbiological eradication rate (microbiological outcome) and clinical efficacy rate (clinical outcome) at 5-9 days after drug administration (visit 2) were 94.9%. Determination of the microbiological and clinical outcomes for the evaluation of recurrence at 4-6 weeks after drug administration (visit 3) were 75.8 and 85.7%, respectively. Of the 48 patients, 40 (83.3%) returned to the clinic at visit 3. The causative bacterial species for cystitis was Escherichia coli in 31 (79.5%) of the 39 patients evaluable for efficacy and safety. Adverse drug reactions observed during the administration and follow-up periods included mild diarrhea and loose stools in 1 patient each, neither requiring any specific treatment. Evaluation of cure at visit 2 in patients in whom the causative bacterial species for the infection was E. coli revealed a microbiological outcome of 93.5%, and clinical outcome was 96.8%. Furthermore, evaluation for recurrence at visit 3 revealed a microbiological outcome of 74.1% and clinical outcome of 82.1%. When the patients were divided by age into an under 60 years of age group and an over 60 years of age group, the microbiological and clinical outcomes determined for evaluation of cure at visit 2 were 96.4 and 92.9%, respectively, and the corresponding rates determined for the evaluation of recurrence at visit 3 were 87.0 and 96.0%, respectively, in the under 60 years of age group. In the over 60 years of age group, the corresponding microbiological outcome and clinical outcome rates evaluated for cure were 90.9 and 100%, respectively, and those evaluated for recurrence were 50.0 and 60.0%, respectively. These results indicate the usefulness of fosfomycin calciu

Single dose fosfomycin trometamol versus multiple dose norfloxacin over three days for uncomplicated UTI in general practice.
    Infection, 1990, Volume: 18 Suppl 2

    The aim of this study was to carry out a small-scale bacteriological comparison between a standard therapy with norfloxacin 400 mg twice daily, and fosfomycin trometamol (3 g) in single dose in uncomplicated urinary tract infections (UTI) in women. Only patients with UTI with cultures showing a bacterial count of 10(5) or more bacteria/ml were included in the study (n = 32; ages 16-75 years). After one week sterile cultures were obtained in 14 of 16 cases in the fosfomycin trometamol group, and in 14 of 16 cases in the norfloxacin group. After one month eradication was confirmed in 13 of 16 patients in the fosfomycin trometamol group, and in nine of 16 patients in the norfloxacin group. Recurrence was seen in one case in the fosfomycin trometamol group, and in five cases in the norfloxacin group. The reinfection and persistence rates were identical (1/16) in both groups. The main clinical symptoms disappeared very rapidly after initiating treatment, and the correlation with the bacteriological data after one week was excellent. Both drugs were well tolerated and the compliance for fosfomycin trometamol was 100%.

A general practitioner multicenter study: fosfomycin trometamol single dose versus pipemidic acid multiple dose.
    Infection, 1990, Volume: 18 Suppl 2

    In order to evaluate the efficacy and safety of fosfomycin trometamol as single dose oral treatment for acute cystitis in women, an open, multicenter comparative study was carried out in general practices in France, 386 women, aged 16 to 75 years, with clinical symptoms of acute cystitis were enrolled in the study to receive either a single 3 g oral dose of fosfomycin trometamol or a five-day course of 400 mg pipemidic acid twice daily. The diagnosis of cystitis was based on clinical symptoms and significant bacteriuria (greater than or equal to 10(5) cfu/ml midstream urine). Follow-up examinations were carried out five to ten and 28 days after the end of treatment, 289 and 244 patients, respectively, were available for clinical and bacteriological evaluation at short-term (five to ten days) and medium-term (28 days) post-treatment follow-up. Both regimens were comparable for clinical and bacteriological efficacy with short-term eradication rates of 122/146 in the fosfomycin trometamol group and 130/143 in the pipemidic acid group. The results of medium-term follow-up were 113/122 and 114/122 for the eradication rates of the respective groups. Both drugs were well tolerated. Side effects were mild and of significantly shorter duration in the fosfomycin trometamol group.

Descriptive management of suspected acute cystitis in adult patients by French general practitioners during remote consultation.
    Infectious diseases now, 2023, Volume: 53, Issue:4

    The main objective of this study was to analyze French general practitioners' (GP) online prescriptions for suspected acute cystitis using a single nationwide teleconsultation platform.. First, a descriptive study of management for suspected cystitis was conducted from the 1st of January to the 31st of December 2020. After which, following pedagogical intervention, a pre/post descriptive analysis of the antibiotics prescribed was carried out.. Some 496,041 teleconsultations (TCs) were carried out in 2020 on the Qare platform. Among them, 15,089 TCs for cystitis with ICD-10 encoding (N30) were analyzed. Fosfomycin trometamol was the most prescribed antibiotic (n = 10297, 69%), while fluoroquinolones (n = 1568, 10.6%) were the second. Urine test strip was prescribed in 3157 (20%) and urine culture in 7033 (47%) of the TCs. July-August 2020 and July-August 2021 were compared and while a significant drop in fluoroquinolone prescriptions and a major increase in Fosfomycin trometamol were observed, there was no change in the prescriptions of urine culture. An average antibiotic conformity rate of 61.5% was observed before the intervention, and 68.8% afterwards.. Cystitis is a recurrent reason for remote consultation. The study demonstrated sizable over-prescription of urine culture, ultrasound, and fluoroquinolones. Intervention should be improved and strengthened to guarantee continuous training and awareness of GP's on appropriate cystitis prescriptions in telemedicine.

Antibiotics in the Treatment of Uncomplicated Cystitis: A Google Trends Analysis.
    Urologia internationalis, 2023, Volume: 107, Issue:6

    Using Google Trends (GT) data, the trend variations for the most common antibiotics used to treat uncomplicated cystitis were analyzed by time and region since 2004.. GT was used to create a "line-graph" that shows how interest in a topic in certain locations has grown or decreased over time. The relative search volume, which is displayed on a scale of 0-100, was used to index the search values for specific phrases. Nitrofurantoin (NFN), fosfomycin (FOS), trimethoprim (TMP), pivmecillinam (PIV), and cefadroxil are among the antibiotics recommended by the European Association of Urology (EAU) and the American Urological Association for the treatment of uncomplicated cystitis. Using the "global" inquiry category, the data was searched "worldwide" from 1 February 2004 to 31 December 2021.. In the regression analysis, all antibiotics exhibited positive trends (p < 0.05). With a steady rise in popularity, NFN is the most popular antibiotic today. Search trend for cefadroxil stayed nearly stable until 2012, the rate of rise in the last 10 years increased, and cefadroxil is the second most popular antibiotic. In the previous 5 years, there was a decline in interest in TMP. In recent years, there was an increase in the trends for FOS and PIV.. Clinicians and patients all around the world increasingly use the web to search for antibiotic therapies for uncomplicated cystitis. Antibiotics used to treat uncomplicated cystitis have various trends in different continents throughout the world. The web trends seem to be compatible with daily use.

Antibiotic Resistance Patterns Among Uropathogens in Female Outpatients Affected by Uncomplicated Cystitis: Focus on Fosfomycin Trometamol.
    International journal of antimicrobial agents, 2023, Volume: 62, Issue:5

    To report the resistance rate against fosfomycin trometamol among outpatient women with symptoms related to urinary tract infections over a 6-year period in a multicentre, cross-sectional study.. Urinary samples were collected from three high-volume laboratories from January 2015 to December 2020. The pattern of resistance to fosfomycin was analysed by using the Vitek II automated system.. A total of 7289 urinary samples were collected and 8321 strains were analysed during the study period. The most commonly isolated uropathogen was Escherichia coli (n = 6583, 79.1%). The mean resistance rate against fosfomycin was 9.7% (range 7.1-11.3). No statistically significant difference was found between the three laboratories (P = 0.53). There was no significant increase in resistance rate during the study period. The mean resistance rate against fosfomycin was higher among extended-spectrum β-lactamase (ESBL)-producing bacteria when compared with non-ESBL-producing strains (10.8% vs. 7.9%; P < 0.001).. Uropathogens isolated from women affected by cystitis remained highly susceptible to fosfomycin. These findings confirm recommendations in international guidelines that advocate fosfomycin trometamol for empirical treatment of uncomplicated cystitis in women.

Oral fosfomycin activity against Klebsiella pneumoniae in a dynamic bladder infection in vitro model.
    The Journal of antimicrobial chemotherapy, 2022, 04-27, Volume: 77, Issue:5

    The use of oral fosfomycin for urinary tract infections (UTIs) caused by non-Escherichia coli uropathogens is uncertain, including Klebsiella pneumoniae, the second most common uropathogen.. A multicompartment bladder infection in vitro model was used with standard media and synthetic human urine (SHU) to simulate urinary fosfomycin exposure after a single 3 g oral dose (fAUC0-72 16884 mg·h/L, t½ 5.5 h) against 15 K. pneumoniae isolates including ATCC 13883 (MIC 2 to >1024 mg/L) with a constant media inflow (20 mL/h) and 4-hourly voiding of each bladder. The impact of the media (CAMHB + G6P versus SHU) on fosfomycin MIC measurements, drug-free growth kinetics and regrowth after fosfomycin administration was assessed. A low and high starting inoculum (5.5 versus 7.5 log10 cfu/mL) was assessed in the bladder infection model.. Compared with CAMHB, isolates in SHU had a slower growth rate doubling time (37.7 versus 24.1 min) and reduced growth capacity (9.0 ± 0.3 versus 9.4 ± 0.3 log10 cfu/mL), which was further restricted with increased inflow rate (40 mL/h) and more frequent voids (2-hourly). Regrowth was commonly observed in both media with emergence of fosfomycin resistance promoted by a high starting inoculum in CAMHB (MIC rise to ≥1024 mg/L in 13/14 isolates). Resistance was rarely detected in SHU, even with a high starting inoculum (MIC rise to ≥1024 mg/L in 2/14 isolates).. Simulated in an in vitro UTI model, the regrowth of K. pneumoniae urinary isolates was inadequately suppressed following oral fosfomycin therapy. Efficacy was further reduced by a high starting inoculum.

The effectiveness of nitrofurantoin, fosfomycin and trimethoprim for the treatment of cystitis in relation to renal function.
    Clinical microbiology and infection : the official publication of the European Society of Clinical Microbiology and Infectious Diseases, 2020, Volume: 26, Issue:10

    We evaluated the effect of renal function on clinical failure rates of nitrofurantoin, fosfomycin and trimethoprim for the treatment of cystitis in primary care.. Data were retrospectively obtained from 78 Dutch general practitioner (GP) practices between 2013 and 2019. Eligible episodes in patients (>11 years) were those requiring 5 days of nitrofurantoin (NF5), single-dose fosfomycin-trometamol (FT1), 3 days of trimethoprim (TMP3) for uncomplicated cystitis, or 7 days of nitrofurantoin (NF7) or trimethoprim (TMP7) for complicated cystitis. Clinical failure was defined as second antibiotic prescription for cystitis or pyelonephritis within 28 days post-prescription. Mixed effects regression analysis was used, with patient and GP practice as random effects and demography, comorbidity, and cystitis history as fixed effects.. Adjusted odds ratios (aORs) for clinical failure per 10mL/min decrease in estimated glomerular filtration rate (eGFR) were 1.05 (95% CI: 1.01-1.09) for NF5 (n = 24,591), 0.96 (95% CI: 0.92-1.01) for FT1 (n = 5359), 0.98 (95% CI: 0.89-1.08) for TMP3 (n = 1064), 1.05 (95% CI: 1.02-1.09) for NF7 (n = 10,628) and 1.02 (95% CI: 0.93-1.14) for TMP7 (n = 831). In uncomplicated cystitis and eGFR ≥60 mL/min, clinical failures occurred in 14.6% (1895/12 980) of NF5-treated, 20.7% (266/1283) of FT1-treated (aOR versus NF5 1.37, 95% CI 1.18-1.59) and 20.8% (66/318) of TMP3-treated patients (aOR 1.42, 95% CI 1.07-1.87 versus NF5). In uncomplicated cystitis and eGFR <60 mL/min, FT1 resulted in 16.0% (39/244) and NF5 in 23.3% clinical failures (110/472), aOR: 0.61, 95% CI: 0.39-0.95).. In eGFR ≥60 mL/min treatment with fosfomycin or trimethoprim for uncomplicated cystitis was associated with more clinical failure than treatment with nitrofurantoin, while in eGFR <60 mL/min nitrofurantoin was associated with more clinical failure than fosfomycin-trometamol. Renal function, if known, should be considered in the clinical decision-making for cystitis treatment.

Cefaclor as a first-line treatment for acute uncomplicated cystitis: a retrospective single-center study.
    BMC urology, 2020, Apr-06, Volume: 20, Issue:1

    Wide-spectrum antibiotics have been favored to treat acute uncomplicated cystitis (AUC) for a long time, leading to the emergence of multi-drug resistant bacteria. We hypothesize that narrow-spectrum antibiotics might mitigate the issue and aim to investigate the clinical efficacy of cefaclor in patients with AUC.. We retrospectively reviewed the clinical data of female outpatients with AUC treated with cefaclor and evaluated the safety and clinical efficacy. Clinical cure was defined as the elimination of clinical symptom under 4 white blood cells (WBCs) per high power field on microscopy.. Overall, 223 women with AUC were enrolled. Escherichia coli was the dominant pathogen (n = 160; 68.6%), followed by Klebsiella species and E. coli-extended spectrum β-lactamase (ESBL) (n = 19; 8.1% and n = 18; 7.7%). Overall success rate was 94.0% (n = 219) and susceptibility rate of cefazolin was 84.1%, which was close to that of levofloxacin (82.9%). Ampicillin showed the lowest rate of 63.7% with a significantly greater resistance rate of 35.3% among all antibiotics (P < 0.001). In the subgroup analysis, the success rate in patients with resistance to levofloxacin or cefazolin was 100% (n = 24) or 93.3% (n = 14). The rate in patients with resistance to both antibiotics was 60.0% (n = 9), and the pathogens in the other 40.0% (n = 6) of patients with treatment failure were E. coli-ESBL.. Cefaclor showed excellent efficacy in AUC patients, even in those with in vitro resistance to cefazolin or levofloxacin. Cefaclor may be considered as a first-line option in patients with AUC and a second-line option for those with levofloxacin treatment failure.

[Recurrent lower urinary tract infection in women: treatment and prevention].
    Urologiia (Moscow, Russia : 1999), 2020, Issue:6

    Antibiotics represent the main drugs for the treatment and prevention of recurrent lower urinary tract infections (UTIs). At the same time, there is no consensus regarding the duration of therapy and the interval between courses.. A total of 50 women aged 18 to 65 years (mean age 44.6+/-13.2 years) with recurrent lower UTIs in the acute stage were treated. All patients were prescribed fosfomycin trometamol (Fosfomycin Esparma, Esparma GmbH, Germany) at a dose of 3 g once every 10 days for 3 months. The changes of clinical and laboratory parameters were evaluated on the 3rd day after the first administration of fosfomycin, and then after 1, 3 and 6 months from the start of treatment.. A decrease in the severity of clinical manifestations of cystitis was seen on the next day after first administration of fosfomycin. By the 3rd day, the ACSS score decreased from the initial 9.2+/-2.1 to 1.4+/-1.0 (p<0.001), while the average urinary frequency changed from 12.3+/-2.3 to 7.5+/-1.4 (p<0.05). After 3 months of therapy, the clinical results virtually did not differ from results on the 3rd day. The therapy was well tolerated; adverse events were noted in 10 patients, but they didnt result in discontinuation of the drug. During follow-up for 3 months after the completion of therapy, 47 (94%) women didnt have recurrence of lower UTI.. the results of the study suggest a high efficiency and good tolerability of fosfomycin when it is prescribed according to specific scheme for the treatment and prevention of recurrent lower UTIs in women.

    To evaluate the efficacy and safety of the antibacterial drug fosfomycin trometamol (Fosfomycin Esparma) in women of reproductive age with acute uncomplicated cystitis.. In order to assess the efficacy and safety of using fosfomycin trometamol (Fosfomycin Esparma), a prospective, non-randomized, uncontrolled study involving 32 women with acute uncomplicated cystitis was carried out. The average patients age was 27.3+/-3.1 years. Before the study, all women underwent a general clinical, bacteriological, and ultrasound examination. Inclusion criteria was the presence of pathognomonic symptoms of acute uncomplicated cystitis. Exclusion criteria were as following: complicated urinary tract infection, anatomical and functional disorders of the urinary tract, comorbidities. All patients were prescribed a study drug at a dose of 3 g, once. The efficiency of therapy was evaluated on days 3 and 14 after administration of Fosfomycin Esparma based on clinical and microbiological cure and safety.. The only bacterial pathogen isolated from the urine was E. coli. In 4 cases (12.5%) strains produced extended-spectrum -lactamase. The sensitivity of E. coli to fosfomycin, piperacillin/tazobactam, amikacin and meropenem was 100%. A resistance to ampicillin was 15.6%, compared to 9.4% for levofloxacin and norfloxacin and 12% for cefotaxime, ceftazidime, cefpoxin. By the 3rd day after receiving fosfomycin, the symptoms of cystitis were resolved in all patients. On day 14, according to the results of the urine culture, there was no growth of bacteria. During the follow-up period, no significant side effects was detected.. Our study showed that antibacterial drug Fosfomycin Esparma in women of reproductive age with acute uncomplicated cystitis is effective and safe. Maintaining a high sensitivity to fosfomycin allows us to recommend this drug as an empirical antibiotic therapy in this cohort of patients.

    To determine whether fosfomycin can be used in treatment of women with acute uncomplicated cystitis in the postpartum period.. The results of treatment of acute uncomplicated cystitis in 51 patients in the postpartum period were retrospectively evaluated. All patients received a single dose 3 g of fosfomycin.. In order to determine clinical efficiency, in all cases laboratory tests were performed prior to and 3 days after treatment. A degree of pain syndrome, the number of voids and urgent episodes were also evaluated. Urine culture was studied before and 7 days after taking fosfomycin. There was a decrease in the number of leukocytes and erythrocytes in urine, number of voids, including urgent episodes. A normalization of urine flora after a single dose of the fosfomycin was noted.. In our research in the repeated analysis of urine culture, the number of bacteria was lower than 104 in all cases, and there was also decrease in the number of voids and intensity of pain syndrome.. The treatment of acute uncomplicated cystitis in women in the early postpartum period has its own characteristics. A single dose of fosfomycin allows to avoid long-term use of the antibiotic and to continue breastfeeding, which is required for the treatment of this disease in lactating women. One of the medicine used in AAC is Fosfomycin Esparma, which has a high safety profile. The use of high-quality antibacterial therapy in these patients to give possibility to avoid complications.

[Efficacy of combined antibacterial-prebiotic therapy in combination with D-mannose in women with uncomplicated lower urinary tract infection].
    Urologiia (Moscow, Russia : 1999), 2019, 12-31, Issue:6

    Acute cystitis is the most common manifestation of uncomplicated urinary tract infection. One of the drugs whose effectiveness in the treatment of patients with INMP has been proven is fosfomycin, which has been on the pharmaceutical market for a long time and is widely used in urological practice. despite the good results of etiotropic therapy, the problem of recurrent UTI remains unresolved, which occurs in about 30% of women within a year after the first episode of cystitis. alternative prophylactic agents, such as probiotics, cranberry preparations, phytopreparations, etc. are increasingly used in prolongation of the inter-relapse period. One such remedy is D-mannose.. to evaluate the effectiveness of D-mannose and the combined drug Ecofomural containing fosfomycin and lactulose in the complex treatment of women with uncomplicated lower urinary tract infection.. 60 women with acute uncomplicated cystitis were examined and treated. By random sampling, all women were divided into 2 groups of 30 people. In group 1, antibiotic therapy with Ecofomural once 1 sachet after urination was prescribed. The product contains 3G of fosfomycin and 1.5 g of prebiotic lactulose. In group 2, a similar antibacterial therapy with the enrichment of the diet with a source of D-mannose (Ecocystin) 1 sachet 1 time per day for 6 months. Evaluation of the effectiveness of antibacterial therapy was carried out on the 3rd and 7th day. It included analysis of dysuric symptoms according to diaries of urination, assessment of pain intensity, laboratory tests. Long-term results of therapy were evaluated within 6 months after taking the antibacterial drug. The examination included a comparative analysis of the frequency of relapses of the disease, filling diaries of urination and laboratory tests.. When treated, all women showed signs of acute cystitis. On the 3rd day of therapy in both groups there was a statistically significant (p<0.05) positive dynamics of the studied parameters. By the 7th day in both groups marked relief of dysuric phenomena and pain. The number of white blood cells in the urine of all patients was within normal values. During a further 6-month follow-up, relapses of the disease were detected in 7 (23.3%) patients in group 1 and in 1 (3.3%) in group 2. Bacteriological examination in group 1 revealed the same pathogen in 5 (16.7%) cases as in the first treatment. The other women had different pathogens.. The results of the study demonstrated the high efficacy and safety of complex therapy with Ecofomural containing fosfomycin and lactulose, in combination with long-term enrichment of the diet with D-mannose (Ecocystin) b in order to prolong the inter-relapse period of uncomplicated lower urinary tract infection.

[NefroCAPS phytolysin in complex management of women with chronic recurrent cystitis].
    Urologiia (Moscow, Russia : 1999), 2018, Issue:1

    Recurrent lower urinary tract infections (UTI) in women are one of the most challenging problems of modern urology, which is associated both with their high incidence and increasing resistance of uropathogens to antibacterial drugs. Due to this fact, the phytotherapy of infectious and inflammatory diseases of the urinary tract has received increased attention.. To investigate the effectiveness of Phytolysin nefroCAPS in the complex management of women with chronic recurrent cystitis.. 50 women with chronic recurrent cystitis underwent a complex examination. They were divided into two groups depending on the treatment they received. Patients of the 1st group (n=27) received a combination therapy: fosfomycin (monural) 3 g (single dose) and Phytolysin nefroCAPS one capsule three times daily for three months. Patients of the 2nd group (n=23) were administered a single 3-g dose of fosfomycin (monural).. Follow-up examinations were performed 1, 3 and six months after initiation of the treatment. In patients of the 1st group, clinical manifestations of the disease disappeared earlier, and they had fewer recurrences than the patients of the 2nd group. Also, bacteriological study of urine showed a more persistent antimicrobial effect among patients of the 1st group.. In patients with chronic recurrent cystitis, plant-based preparation Phytolysin nefroCAPS administered concurrently with an antibacterial drug is more effective than antibiotic monotherapy.

    Lower urinary tract infection are a common urologic disease, but a therapy is not always optimal.. to evaluate the compliance of prescriptions made by urologists in treatment of patients with lower urinary tract infection, in particular with acute uncomplicated cystitis.. A specially designed questionnaire was filled out by 161 urologists from Novosibirsk, Barnaul and Krasnoyarsk, as well as participants of VII Congress of urologists of Siberia.. The survey showed that 34.8%, 27.9%, 22.4% and 14.9% of urologists had 6-10, 11-20, 1-5 and more than 20 patients with acute uncomplicated cystitis a month, respectively. According to results, 91.9% of urologists are familiar to National guidelines on treatment of lower urinary tract infections and 91.2% of doctors consider them to be reasonable. Among those surveyed, 29.2% of urologists believe that National Guidelines differ from European Guidelines; 95.7% of participants adhere to recommendations, but only 47.4% respect it almost always, 16.9% do it in half of cases and the remaining 35.7% comply with them in less than 40% cases. Moreover, 86.4% of urologists started a treatment of acute cystitis with antimicrobial therapy and preferred fosfomycin in 41.0%, nitrofurans in 20.9%, fluoroquinolones in 21.6% and cephalosporins in 16.5% cases, respectively. Almost all respondents (93.8%) are convinced that antibiotic therapy should be accompanied by phytotherapy, and 71.5% of urologists administer Canephron.. In the urologic community there are controversies in the treatment of patients with acute uncomplicated cystitis. The choice of therapy is not always optimal.

[Efficiency of fosfomycin trometamol for treatment of acute uncomplicated cystitis].
    Urologiia (Moscow, Russia : 1999), 2018, Issue:6

    Acute cystitis is the most common type of uncomplicated urinary tract infection. A choice of antibiotics for the treatment depends not only on the spectrum of antimicrobial activity against pathogens, but also on the pharmacokinetic properties, due to high urine concentration after single or double use is needed. In addition, high safety profile and acceptable cost are important. Fosfomycin is one of the drugs whose efficiency in treating of patients with lower urinary tract infection is proved. It has been on the pharmaceutical market for a long time and is widely used in urologic practice. There is a risk of a decreasing of efficiency of fosfomycin, considering sustained downward trend in the sensitivity of uropathogens. This causes a need to monitor the resistance of main uropathogens to fosfomycin. In this article our experience of using of fosfomycin for the treatment of women with acute uncomplicated cystitis is presented.. to evaluate an efficiency of fosfomycin trometamol for treatment of women with acute uncomplicated cystitis.. During the period from September to November 2018, we performed an examination and treatment of 57 women with acute uncomplicated cystitis aged from 19 to 40 years. All patients were prescribed 1 sachet of Fosfomycin Esparma (fosfomycin trometamol) after urination. The examinations were carried out on the 1st, 3rd and 7th day, including an evaluation of urination frequency, urgency, nocturia and pain intensity. In addition, urinalysis and urine culture using solid media with determination of the type of pathogens, sensitivity to antibiotics and the level of bacteriuria were also performed.. Baseline, all patients had complaints of pain in the bladder, urethral discomfort and frequent urination, but passing only small amount of urine. All women had leucocyturia and bacteriuria. By the 3rd day after receiving fosfomycin, urinary disturbances persisted in 22.8% patients and 17.5% of women still described pain. Mild leucocyturia was determined in 42% cases. Urine culture was negative. By the 7th day after the start of therapy, all clinical and laboratory data were returned to the normal values in all patients.. Based on the results of our study, we recommend the fosfomycin as the first-line treatment of uncomplicated lower urinary tract infection due to broad spectrum, low resistance of uropathogens, high safety profile and good compliancy.

Fosfomycin tromethamine for the Treatment of Cystitis in Abdominal Solid Organ Transplant Recipients With Renal Dysfunction.
    The Annals of pharmacotherapy, 2017, Volume: 51, Issue:9

    Urinary tract infection (UTI) after abdominal solid organ transplantation (SOT) is associated with significant morbidity and mortality. Fosfomycin tromethamine (FOS), a uroselective antibiotic, is FDA approved for uncomplicated UTIs in women and is used off-label for complicated UTIs and prostatitis in men. Literature supporting the use of FOS in the SOT population is limited, and efficacy is questioned in the setting of renal dysfunction.. To evaluate the success of FOS for the treatment of cystitis in SOT patients with renal dysfunction.. This was a single-center, retrospective study using medical records. SOT recipients receiving at least 1 dose of FOS for treatment of cystitis between January 1, 2009, and April 30, 2015, were included. Treatment outcomes were analyzed with respect to renal function.. A total of 76 courses of FOS were identified in 64 patients. The renal dysfunction arm (creatinine clearance [CrCl] < 40 mL/min) included 33 patients with 39 FOS courses; the normal renal function arm (CrCl ≥ 40 mL/min) included 31 patients with 37 FOS courses. Mean CrCl was 23.3 ± 9.7 mL/min for the renal-dysfunction group and 65 ± 29.3 mL/min for the normal renal function group ( P < 0.01). No significant difference in treatment success was noted between CrCl <40 mL/min and CrCl ≥40 mL/min (31 [80%] vs 34 [92%], P = 0.12) in a unilateral analysis. After adjusting for confounders in a multivariable analysis, there was no difference in the risk of failure between CrCl <40 mL/min and CrCl ≥40 mL/min groups ( P = 0.70).. FOS appears to be successful for the treatment of cystitis in SOT recipients in the setting of renal dysfunction.

Local epidemiology and resistance profiles in acute uncomplicated cystitis (AUC) in women: a prospective cohort study in an urban urological ambulatory setting.
    BMC infectious diseases, 2017, 10-16, Volume: 17, Issue:1

    Acute uncomplicated cystitis (AUC) is a common ailment in the urological setting. Guidelines for urinary tract infections are based on large-scale multi-centre, epidemiological and international studies. The objective of this observational study was to establish whether the results of a multi-centre study on the resistance profile of Escherichia coli (E. coli) in patients with AUC could be directly applied to an urological practice in a major European city or whether there are divergences in the resistance profile.. An observational study was applied prospectively to 502 patients with AUC between January 2015 and January 2017). Personal data were anonymised. Exclusion criteria were the patient's age (<18) and treatment with an antibiotic in the week preceding examination.. The average age was 32 (range 18-56). The most commonly detected bacteria was E. coli with 86%, followed by Enterococcus faecalis with 10% and Klebsiella pneumoniae with 4%. Resistance tests showed E. coli to be highly sensitive to fosfomycin (99.2%), nitrofurantoin (98.1%) and cefpodoxime (92.9%). E. coli exhibited resistance to ciprofloxacin (CIP) in 15.1%, to trimethoprim/sulfamethoxazole (TRS) in 25.2% and to amoxicillin/clavulanic acid (AMC) in 34% of cases.. The comparison between data from this study and data from a multi-centre European (ECO-SENSI, ECO-SENSII and the 2014 update) showed relatively good sensitivity rates for fosfomycin and nitrofurantoin but significant differences in respect of resistance levels to TRS, CIP and AMC. AUC should therefore only be treated with TRS, CIP and AMC after a susceptibility test has been carried out.

Fosfomycin for the Treatment of Cystitis in the Abdominal Solid Organ Transplant Population.
    Pharmacotherapy, 2017, Volume: 37, Issue:5

    To evaluate the use of fosfomycin (FOS) at the single-dose regimen approved by the U.S. Food and Drug Administration as well as off-label multidose regimens for the treatment of cystitis after abdominal solid organ transplant (aSOT).. Retrospective study.. Tertiary academic medical center.. Adult inpatients with history of aSOT receiving FOS between January 1, 2009, and April 30, 2015, for the treatment of cystitis.. Seventy-six courses of FOS were identified in 64 patients. Overall treatment success was 85.5%, with 11 failed treatment courses. Enterococcus was isolated in 59.3% of courses, of which 72.2% were vancomycin-resistant enterococci (VRE). Gram-negative organisms comprised a quarter of isolated bacteria, with most resistant to three or more antimicrobial classes. In the 11 failed treatment courses, 90% were targeted against enterococcus, of which 82% were VRE. Six of these failures (54%) were successfully retreated with uroselective therapy (FOS or nitrofurantoin). No significant difference in the success rate of single-dose versus multidose therapy was seen (80.6% vs 90%, p=0.33). Concomitant systemic antibiotics for other indications were present in 36.8% of courses, and they were significantly more frequent in the multidose group (67.5% vs 47.2%, p=0.04). However, multivariable logistic regression analysis found that after adjustment for broad-spectrum antibiotic use, no statistically significant difference in failure rates was found between the two regimens (p=0.42).. FOS appears to be successful in the treatment of cystitis in aSOT recipients. Multidose therapy did not significantly improve success over a single-dose regimen. Further prospective studies are needed to elucidate the true efficacy of FOS in the aSOT population.

[Complex treatment of chronic cystitis in women].
    Urologiia (Moscow, Russia : 1999), 2016, Issue:4

    Evaluation of the efficacy and safety of Phytolysin in complex treatment of female patients with chronic cystitis.. 40 women with chronic cystitis were examined from January 2016 to March 2016. Depending on the treatment, all patients were divided into two groups of 20 people. Main group of patients was treated with Fosfomycin (Monural) and Phytolysin. Control group of patients received monotherapy with fosfomycin.. The results were assessed at 1 and 2 months after initiation of therapy. Rapid normalization of the status and laboratory parameters, improvement of dynamics of the endoscopic view was observed in main group of patients.. The complex of biologically active substances contained in Phytolysin has antimicrobial, anti-inflammatory, antispasmodic, and immunomodulatory effects, promotes the normalization of urodynamics of lower urinary tract, reduces the risk of relapse of chronic recurrent cystitis. Thus, Phytolysin can be recommended as a component of complex therapy of exacerbations of chronic cystitis, as well as a drug for prevention of the disease in disease-free periods.

Activity of fosfomycin and comparison of several susceptibility testing methods against contemporary urine isolates.
    International journal of antimicrobial agents, 2015, Volume: 46, Issue:6

    Fosfomycin is recommended as first-line treatment for acute uncomplicated cystitis in women. It has demonstrated in vitro activity against a variety of pathogens; however, a paucity of data are available from the USA. We determined the susceptibility of a collection of urine isolates to fosfomycin and compared multiple methods of susceptibility testing. Consecutive non-duplicate Enterobacteriaceae, enterococci and Pseudomonas aeruginosa isolates were collected from the clinical microbiology laboratory between August 2013 and January 2014. Isolates represented hospitalised or emergency department patients with monomicrobial bacteriuria. Fosfomycin MICs were determined in duplicate, on separate days, by Etest and disk diffusion and results were compared with agar dilution. Nitrofurantoin and ciprofloxacin were used as comparators. MIC results were categorised using Clinical and Laboratory Standards Institute interpretive criteria for Escherichia coli and Enterococcus faecalis. Correlation between the three testing methods was evaluated. Overall susceptibility to fosfomycin was 94.4%, 93.5% and 87.9% by agar dilution, disk diffusion and Etest, respectively. Five fosfomycin-resistant isolates were identified, including two Morganella morganii, one P. aeruginosa, one Proteus mirabilis and one Enterobacter aerogenes. Across all organisms, rates of essential agreement, categorical agreement, minor errors, major errors and very major errors for Etest/disk diffusion compared with agar dilution were 77.3%/NA, 89.5/93.8%, 7.1/5.0%, 3.6/1.3% and 0/0%, respectively. Fosfomycin displayed fairly consistent activity against a majority of isolates collected when using the susceptibility breakpoint of 64 μg/mL. MICs for E. coli were particularly low (≤2 μg/mL). These data lend support to current guidelines that recommend fosfomycin as empirical first-line therapy for uncomplicated UTI.

Intravesical therapy in recurrent cystitis: a multi-center experience.
    Journal of infection and chemotherapy : official journal of the Japan Society of Chemotherapy, 2013, Volume: 19, Issue:5

    Approximately 20-30% of women suffer from recurrent cystitis. Recently, the problem of bacterial internalization, especially by Escherichia coli, has been significantly emerging as the main cause of recurrent episodes. It is believed that such a process is favored by damage to the urothelial mucous membrane. Concerning this, intravesical therapy with hyaluronic acid alone or in association with chondroitin sulfate was shown to improve urothelium thickness and reduction of bacterial load in the urine. The aim of our study was to assess whether intravesical therapy with hyaluronic acid (HA) and chondroitin sulfate (CS) is more effective than antibiotic therapy in reducing episodes and symptoms of recurrent urinary tract infections. We compared the number of recurring episodes in three groups of patients affected by recurrent urinary tract infections assigned to three different therapeutic regimens: the first group was treated only with HA and CS, the second group with HA and CS associated with fosfomycin, and the third group was treated only with fosfomycin (F). We assessed the number of recurrent episodes for each patient that occurred during a 6- to 12-month follow-up. The results showed 72.7% of patients in the HA-CS group, 75% in the fosfomycin + HA-CS group, and only 30.4% in the fosfomycin group were event free at follow-up. The results were analyzed using the Fisher's exact test. In conclusion, intravesical therapy with hyaluronic acid and chondroitin sulfate is an effective therapeutic approach to treat and prevent episodes of recurrent cystitis.

French results of the ARESC study: clinical aspects and epidemiology of antimicrobial resistance in female patients with cystitis. Implications for empiric therapy.
    Medecine et maladies infectieuses, 2012, Volume: 42, Issue:2

    Uncomplicated cystitis is one of the most frequent community infections. We report the French results of the international ARESC study on the clinical aspects, epidemiology, and antimicrobial susceptibility of uropathogens.. Female patients between 18 and 65 years of age, with symptoms of uncomplicated cystitis, were investigated clinically with urinalysis and urine culture. Uropathogens were identified and their susceptibility was tested with nine antimicrobials.. Four thousand and four hundred patients were included, 871 in France, forming the largest national cohort. Urine culture was positive (cfu≥10(4)/ml) in 550 (63.1%); 533 (96.9%) presented with a single bacterium infection. 488 uropathogens, collected from 479 patients, were analyzed. The most frequent were: Escherichia coli (83.8%), Staphylococcus saprophyticus (4.3%), Proteus mirabilis (3.1%), enterococci (1.2%), and Klebsiella pneumoniae (1.0%). E. coli was highly susceptible to fosfomycin (99.0%) (97.1%), nitrofurantoin (97.3%), and ciprofloxacin (98.3%). The lowest susceptibility rates were found for ampicillin (60.9%) and cotrimoxazole (87.8%). Fosfomycin (97.8%), ciprofloxacin (98.3%), and nitrofurantoin (91.5%) had the highest susceptibility rate. The lowest susceptibility rates were observed with ampicillin (61.4%) and cotrimoxazole (86.5%).. Fosfomycin, pivmecillinam (not available in France), and nitrofurantoin have preserved their in vitro activity and are suitable for empiric therapy. Cotrimoxazole (trimethoprim+sulfamethoxazole) and fluoroquinolones are not usually recommended as first intention drugs for the empiric therapy of uncomplicated cystitis, because of increasing resistance rates.

Different biosynthetic pathways to fosfomycin in Pseudomonas syringae and Streptomyces species.
    Antimicrobial agents and chemotherapy, 2012, Volume: 56, Issue:8

    Fosfomycin is a wide-spectrum antibiotic that is used clinically to treat acute cystitis in the United States. The compound is produced by several strains of streptomycetes and pseudomonads. We sequenced the biosynthetic gene cluster responsible for fosfomycin production in Pseudomonas syringae PB-5123. Surprisingly, the biosynthetic pathway in this organism is very different from that in Streptomyces fradiae and Streptomyces wedmorensis. The pathways share the first and last steps, involving conversion of phosphoenolpyruvate to phosphonopyruvate (PnPy) and 2-hydroxypropylphosphonate (2-HPP) to fosfomycin, respectively, but the enzymes converting PnPy to 2-HPP are different. The genome of P. syringae PB-5123 lacks a gene encoding the PnPy decarboxylase found in the Streptomyces strains. Instead, it contains a gene coding for a citrate synthase-like enzyme, Psf2, homologous to the proteins that add an acetyl group to PnPy in the biosynthesis of FR-900098 and phosphinothricin. Heterologous expression and purification of Psf2 followed by activity assays confirmed the proposed activity of Psf2. Furthermore, heterologous production of fosfomycin in Pseudomonas aeruginosa from a fosmid encoding the fosfomycin biosynthetic cluster from P. syringae PB-5123 confirmed that the gene cluster is functional. Therefore, two different pathways have evolved to produce this highly potent antimicrobial agent.

Community infections caused by extended-spectrum beta-lactamase-producing Escherichia coli.
    Archives of internal medicine, 2008, Sep-22, Volume: 168, Issue:17

    Extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli is an increasingly important group of community pathogens worldwide. These organisms are frequently resistant to many of the antimicrobial agents usually recommended for the treatment of infections caused by E coli, such as penicillins, cephalosporins, fluoroquinolones, and trimethoprim-sulfamethoxazole. Data concerning risk factors, clinical features, and therapeutic options for such infections are scarce.. A case-control study was performed to investigate the risk factors for all types of community-acquired infections caused by ESBL-producing E coli in 11 Spanish hospitals from February 2002 to May 2003. Controls were randomly chosen from among outpatients with a clinical sample not yielding ESBL-producing E coli. The clinical features of these infections were investigated in the case patients. The efficacy of fosfomycin tromethamine and amoxicillin-clavulanate potassium was observationally studied in patients with cystitis.. A total of 122 cases were included. Risk factors selected by multivariate analysis included the following: age older than 60 years; female sex; diabetes mellitus; recurrent urinary tract infections (UTIs); previous invasive procedures of the urinary tract; follow-up in outpatient clinic; and previous receipt of aminopenicillins, cephalosporins, and fluoroquinolones. Urinary tract infections accounted for 93% of the cases; 6% of the patients were bacteremic and 10% needed hospitalization. The cure rate of patients with cystitis was 93% with fosfomycin therapy (all isolates were susceptible); among patients treated with amoxicillin-clavulanate, cure rates were 93% for those with susceptible isolates (minimum inhibitory concentration < or =8 microg/mL) and 56% for those with intermediate or resistant isolates (minimum inhibitory concentration > or =16 microg/mL) (P = .02).. In predisposed patients, ESBL-producing E coli is a notable cause of community-acquired infection, and particularly UTI. Fosfomycin and amoxicillin-clavulanate appear to be effective for cystitis caused by susceptible isolates.

    The aim is to evaluate the effectiveness of AM3 (Inmunoferon) in the treatment of the recurrent cystitis in women in order to know the rate of good results, previously to design a clinical trial.. Twenty-four women who had been diagnosed of two cystitis episodes in the previous 6 months without cure by antibiotic treatment were admitted to the study. Standard antibiotic treatment and 3 daily grammes of AM3 was given for 9 months. Infection and irritative symptoms during micturition rate were evaluated at the inclusion date and afterwards, at the first, third, sixth and nineth month.. Nineteen patients finished the study. The infection rate decreased from 100% at the inclusion date to 26% in the first month and then it became stable about 50%. Irritative symptoms during micturition decreased from 46% at the inclusion date to a rate lower than 10% in the 4 controls running.. AM3 reduced evident urinary infection in a 50% and irritative symptoms during micturition in a 90%. Control clinical trials are needed to confirm the AM3 effects on this pathology.

    The therapeutic effectiveness of a single oral dose (60 and 200 mg/kg body weight) of fosfomycin trometamol (FT), norfloxacin, trimethoprim sulfamethoxazole (Bactrim) and pipemidic acid against experimental cystitis in the rat were compared. Infections were produced with clinical isolates of Klebsiella pneumoniae, Proteus mirabilis and Escherichia coli in a total of 135 Sprague-Dawley albino rats. Oral treatment with all four drugs consistently lowered the numbers of CFU in bladder tissue, especially E. coli and P. mirabilis. Fosfomycin trometamol appeared to be as effective as norfloxacin for treatment of E. coli cystitis even thoughs its minimal inhibitory concentration (MIC) in vitro is 100 times greater than that of the quinolonic antibiotic. Fosfomycin trometamol, pipemidic acid and Bactrim were equally effective against P. mirabilis infection, but FT was less active than norfloxacin or Bactrim for treatment of K. pneumonia cystitis. In conclusion, single dose treatment with fosfomycin trometamol was effective for treatment of experimental cystitis in the rat and might, by extrapolation, be of use in clinical practice for single dose treatment of uncomplicated urinary tract infections.

    The urinary concentrations of fosfomycin trometamol, norfloxacin, pipemidic acid and cotrimoxazole were studied at various times after oral administration of drugs in healthy volunteers. Using the same urine, the bactericidal activity of four antimicrobial agents against Escherichia coli, Proteus mirabilis and Klebsiella pneumoniae in an in vitro model simulating the treatment of bacterial cystitis was also evaluated. The results obtained show that very high concentrations of the drugs were achieved in urine particularly after the oral administration of the fosfomycin trometamol. In the bladder model bactericidal activity of fosfomycin trometamol, norfloxacin and pipemidic acid were higher than that of cotrimoxazole; no resistant mutants to drugs were selected over a period of 24 h.

    Fosfomycin (FOM) is an antibiotic which inhibits phospho(enol)pyruvic acid transferase. Fifty-five patients with cystitis were treated with the drug for 7 days, at oral doses of 1 g for 3 times a day. Adult females under 70 years of age, visiting the clinic within 2 weeks after the onset, were classified as cases with typical simple cystitis with confirming the bladder irritability, pyuria and bacteriuria. The treatment was effective for 95.0% of these cases. Two cases with atypical cystitis caused by Klebsiella pneumoniae poorly responded to the drug.

The trometamol salt of fosfomycin: microbiological evaluation.
    European urology, 1987, Volume: 13 Suppl 1

    The spectrum of activity of fosfomycin and its pharmacological behaviour make it an attractive candidate for the oral treatment of uncomplicated urinary tract infection. Various factors affect the antibacterial activity so that results in different culture media vary widely. The highest activity was displayed in Eugonbroth and such results correlated well with those obtained in pooled human urine. The activity was enhanced in acid conditions such as commonly exist in infected urine. Glucose-6-phosphate potentiated the activity of fosfomycin against Escherichia coli and some other bacteria when tested in Eugonbroth (but less predictably in human urine) and the potentiating effect may be necessary in order to obtain therapeutically meaningful results in susceptibility tests. Experiments in an in vitro model of the treatment of bacterial cystitis (carried out in the absence of glucose-6-phosphate) indicated that both sensitive and 'resistant' strains of E. coli respond to concentrations of fosfomycin achievable by high-dose oral therapy with the trometamol salt. Resistance did not emerge in previously sensitive strains (or in one of the 2 'resistant' strains), providing a high peak level of antibiotic was achieved.

Correlation between bactericidal activity of fosfomycin trometamol in an in vitro model of the urinary bladder and susceptibility testing.
    European urology, 1987, Volume: 13 Suppl 1

    The present study was undertaken to define an interpretative guideline for disk diffusion susceptibility testing with fosfomycin trometamol, a new antimicrobial agent which has been developed for the treatment of urinary tract infections. Two potencies of fosfomycin disk were used: 50 and 200 micrograms, prepared in the presence and absence of glucose-6-phosphate. To verify the reliability of the results obtained in susceptibility testing, we have also evaluated the bactericidal activity of fosfomycin trometamol versus sensitive and resistant strains in an 'in vitro' model simulating the hydrokinetic aspects involved in the treatment of bacterial cystitis. The data obtained evidenced the role of glucose-6-phosphate in antimicrobial susceptibility tests as well as the importance of the urinary antibiotic concentrations to define sensitive and resistant bacteria. On the basis of our results, we recommend that a 200-microgram disk of fosfomycin containing 50 micrograms of glucose-6-phosphate should be used in antimicrobial susceptibility testing with fosfomycin trometamol.

Microbiological basis for the use of fosfomycin trometamol as single-dose therapy for simple cystitis.
    Chemioterapia : international journal of the Mediterranean Society of Chemotherapy, 1986, Volume: 5, Issue:4

    Fosfomycin trometamol (FOT), a new soluble salt of fosfomycin, was developed especially for single-dose treatment in uncomplicated urinary tract infections. In this study, the minimum inhibitory concentrations (MICs) of FOT were measured both in nutrient broth and human urine and compared with calcium fosfomycin, pipemidic acid and cotrimoxazole. A total of 300 bacterial strains of different species from recent urinary infections were studied. Staphylococcus aureus showed the lowest MIC (0.38 micrograms/ml) and Pseudomonas spp. the highest (50 micrograms/ml) with fosfomycin salts in nutrient broth. The MIC of fosfomycin resulted in being higher than those for pipemidic acid and cotrimoxazole against Escherichia coli and Proteus rettgeri and lower for all the other species considered. The MIC values increased about ten times when urine was used as medium. No differences were observed between the two fosfomycin salts. The fosfomycin concentrations of 137-1500 micrograms/ml, easily obtained in urine of healthy adult subjects after a single dose of FOT (3g of fosfomycin), were able to kill all the strains, with the exception of Streptococcus faecalis. The bacterial adhesion of a resistant microorganism (P. aeruginosa) to the cells of the urinary tract, showed a 50% reduction after FOT treatment.
