Azithromycin in the treatment of rectogenital
Azithromycin was recommended as the first-line therapeutic regimen for treatment of genital infections in men and women by the Centers for Disease Control in 1998. A series of studies of azithromycin for treatment of rectal chlamydial infection in men who have sex with men (MSM) found that azithromycin was significantly less effective than doxycycline.. Literature on treatment of rectal. The available data suggests that single-dose azithromycin is not as effective as azithromycin for the treatment of rectal infection in MSM and women. Most of these data have been retrospective or from observational studies. Final recommendations will depend on the outcome of prospective, randomized, treatment studies. We may also need to examine other dosage regimens for azithromycin.

Treatment of uncomplicated genital Chlamydia trachomatis infections in adults.
To prepare the 2001 sexually transmitted disease treatment guidelines of the Centers for Disease Control and Prevention, recently published articles and abstracts concerning advances in the treatment of uncomplicated Chlamydia trachomatis genital infections in adults were reviewed. Questions about treatments were posed and answered according to the results of efficacy studies and clinical trials. Recent studies have continued to demonstrate the similar efficacy of doxycycline and azithromycin. Because compliance with doxycyline remains a concern, administration of single-dose azithromycin therapy in the clinic presents a potential advantage for patients whose adherence is questionable. Because few systematically collected data have been published concerning the safety and efficacy of azithromycin use in pregnancy, the guidelines continue to recommend treatment with erythromycin or amoxicillin. Nevertheless, because of azithromycin's less frequent side effects and improved adherence, increasing numbers of obstetricians in the United States are using azithromyin to treat pregnant women with uncomplicated C. trachomatis infections.

New treatments for Chlamydia trachomatis genital infection.
To provide information for the formulation of treatment guidelines, we review recently published articles and abstracts on advances in the treatment of Chlamydia trachomatis genital infection. We ask specific questions about new treatments that are answered on the basis of the results of clinical trials and efficacy studies. New, potentially effective treatments for C. trachomatis genital infection include azithromycin and ofloxacin. Clinical studies indicate that the efficacy of these agents is equivalent to that of the current recommended agent doxycycline. Both azithromycin and ofloxacin are substantially more expensive than doxycycline. Azithromycin has the advantage of being given as a single dose, while doxycycline and ofloxacin are administered for 1 week. Issues of compliance, cost, and toxicity for specific patients should be considered when deciding whether to treat C. trachomatis genital infections with these agents.

[Azithromycin and genital infections].
The lower genital tract infections due to Chlamydia trachomatis are frequent, essentially occurring in young patients, with possible complications and severe sequela, particularly in women where the sterility risk is one of the major consequences. If an effective treatment could be systematically proposed, a good compliance (easy administration and good toleration) is one of the key factor to success. In this context, the azithromycin displays numerous advantages. The azithromycin in vitro activity on Chl. trachomatis strains is permanent with MIC comprised between 0.06 and 0.125 micrograms/ml, with an activity equivalent to those of other macrolides, to tetracyclines and quinolones. Different animal models allow to demonstrate the curative activity of the azithromycin administered as a single dose, at dosage regimen equivalent to those used in man, and a prophylactic activity on the salpingitis onset in provoked Chl. trachomatis infections. Several comparative clinical studies with azithromycin administered as a 1 g single dose displayed very satisfactory results with 98% of bacterial eradication, identical to those obtained with reference treatment. On the other hand, restrictions to the product use are a less constant activity against Neisseria gonorrhoeae and a lack of efficacy on Mycoplasma hominis. The efficacy on Treponema pallidum remains to be clinically tested.

Biological and Behavioral Factors Associated With Positive Chlamydia Retests.
Repeat chlamydia detection after treatment is common, and there is concern that treatment failure may be a cause.. Within a randomized trial, we established a prospective cohort of 600 participants with anogenital chlamydia diagnoses (200 each of women, heterosexual men, and men who have sex with men [MSM]). Participants were invited for repeat testing at 3 months and to complete a behavioral survey at 4 months. Positive samples were analyzed for organism DNA load and genovar. We estimated repeat chlamydia positivity, reinfection and treatment failure rates, and investigated the biological and behavioral factors associated with a repeat positive test.. A total of 290 participants (100 women, 89 heterosexual men, 101 MSM) were retested at 1 to 4 months, with 43 repeat positives, including 26 classed as reinfection and 9 as treatment failures. Comparing MSM with heterosexual men and women combined, repeat positivity was higher (20.8% vs 11.6%, P = 0.04), and treatment failure was higher (6.9% vs 1.1%, P = 0.01), but there was no difference in reinfection rates (11.9% vs 7.4%, P = 0.21). Among MSM, the odds of repeat positivity increased by 90% with each additional log organism load in the original specimen (baseline) (adjusted odds ratio, 1.9; 95% confidence interval, 1.1-3.2). Among heterosexuals, the odds of repeat positivity decreased by 10% with each additional week delay in being retested for chlamydia (adjusted odds ratio, 0.9; 95% confidence interval, 0.8-0.9).. Positive retests were more common among MSM than heterosexuals. Treatment failure was more common in MSM with rectal chlamydia, reinforcing concerns about azithromycin treatment failure.

Randomized, double-blind, multicenter safety and efficacy study of rifalazil compared with azithromycin for treatment of uncomplicated genital Chlamydia trachomatis infection in women.
A randomized, double-blind study comparing single-dose chlamydia therapies of oral rifalazil (25 mg) and azithromycin (1 g) was conducted in 82 women with uncomplicated genital Chlamydia trachomatis infection. The microbiologic cure rate of C. trachomatis with rifalazil (n = 33) was 84.8% at the visit on day 22 to 26 (test-of-cure visit), versus 92.1% with azithromycin (n = 38), and the number of treatment failures in each group was 5 and 3, respectively. The difference in cure rate was -7.3%, with a lower limit of the 95% confidence interval (95% CI) of -22.5, and thus, noninferiority was not established at the prespecified margin (lower limit of CI of -15%). The overall treatment-emergent adverse event (TEAE) and treatment-related TEAE rates were lower in the rifalazil group (68% and 55%) than in the azithromycin group (71% and 62%), respectively. Subjects classified as treatment failures at day 22 to 26 had a lower mean plasma concentration of rifalazil at the visit on day 8 to 12 than those classified as treatment cures, but this difference was not significant; however, the levels were similar for both groups at the visit on day 22 to 26. A single 25-mg dose of rifalazil was well tolerated and eradicated C. trachomatis in most of these women with uncomplicated genital C. trachomatis infection. (The study was registered at clinicaltrials.gov under registration no. NCT01631201).

Micronucleus frequency in women with genital Chlamydia Trachomatis infection before and after therapy.
The main aim of the present study was to investigate the influence of infection with the intracellular bacterium Chlamydia trachomatis, and subsequent treatments with oral doxycycline or azithromycin on the frequency of micronuclei (MN) in peripheral blood lymphocytes of adult female patients receiving standard doses of these drugs. The frequency of micronuclei was measured in the lymphocytes of 38 newly diagnosed adult women with genital C. trachomatis infection. Samples were taken before and after the therapy, and from 50 healthy control females. The therapy was taken orally during 10 days at 2 x 100 mg per day, and then for another 10 days at 1 x 100 mg per day for doxycycline, and as a single dose of 1g for azithromycin. Isolated lymphocytes from all subjects were cultured by use of the whole-blood method and blocked in metaphase with cytochalasin B (Cyt B). One thousand binucleate cells per subject were scored according to published criteria. The frequency of micronuclei was not significantly higher in samples of infected females before therapy, compared with the baseline frequency in healthy control females (p > 0.05). In patients who received doxycycline, the micronucleus frequency after the end of therapy was significantly higher than before treatment (p < 0.001). The mean frequency of micronuclei in females after the end of the therapy with azithromycin did not show an increase (p > 0.05). The application of linear regression analysis showed that the difference in micronucleus frequency before and after therapy (effect of the antibiotics) was affected by the therapy type. Age and smoking did not affect micronucleus frequency in analyzed samples of patients (p = 0.078, 0.579). We conclude that C. trachomatis infection does not induce micronuclei in peripheral blood lymphocytes of infected adult female patients. Therapy with doxycycline significantly increases the micronucleus frequency in lymphocytes of treated patients, but treatment with azithromycin does not induce micronuclei.

Efficacy and safety of azithromycin versus lymecyline in the treatment of genital chlamydial infections in women.
To compare the clinical and microbiological efficacy of azithromycin in curing chlamydial infections in women with that of lymecycline, and with a view of the possibility of minimizing the problem of compliance by means of single-dose administration, 146 women with culture-positive Chlamydia trachomatis infections were randomly assigned to treatment with a 1 g bolus dose of azithromycin or a 10-day course of lymecycline 300 mg twice daily. Clinical and microbiological evaluations were performed and adverse effects monitored at check-ups after 15-35 and 40-65 days. Of the 146 patients enrolled in the study, 120 were evaluable. At the second check-up, C. trachomatis was found to have been eradicated in all patients in both treatment groups. Of the 51 patients who had clinical signs and symptoms of genital infection at enrolment, 96% (22/23) of those in the azithromycin group were considered cured (n = 18) or improved (n = 4), as compared with 100% (28/28) of those considered cured (n = 22) or improved (n = 6) in the lymecycline group. Adverse events related, or possibly related, to treatment were reported by 16 (21.6%) of the lymecycline group, but by only 6 (8.3%) of the azithromycin group. The 2 drugs were comparable with regard to microbiological and clinical efficacy in the treatment of genital chlamydial infection in women. The markedly lower rate of side-effects associated with azithromycin may be a feature conducive to patient compliance.

Comparison of azithromycin and ceftriaxone for the treatment of chancroid.
We conducted a randomized, unblinded, prospective study designed to determine the efficacy of single-dose azithromycin for the treatment of chancroid. Men and women 16 years of age and older who had darkfield-negative genital ulcers that were clinically suspected to be caused by Haemophilus ducreyi and who attended urban sexually transmitted disease clinics or presented to hospital emergency departments were enrolled in the study. Patients were randomized to receive 250 mg of ceftriaxone im or 1 g of azithromycin orally, both given as a single dose. They were followed for up to 23 days after treatment. For 65 patients, cultures were positive for H. ducreyi; there were 68 patients whose cultures were negative for both H. ducreyi and herpes simplex virus and who had no evidence of syphilis. All 133 patients returned for at least one follow-up visit. At the time of the last follow-up visit, all 32 patients whose cultures were positive for H. ducreyi and who were treated with azithromycin were clinically cured. In all 33 culture-positive cases in which ceftriaxone was used, there was either clinical improvement or cure at the time of the patient's last follow-up visit. In addition, azithromycin and ceftriaxone were equally effective in healing ulcers for which cultures were negative. We conclude that a single 1-g oral dose of azithromycin is as effective as a 250-mg im dose of ceftriaxone for the treatment of chancroid.

High treatment failure rate is better explained by resistance gene detection than by minimum inhibitory concentration in patients with urogenital Chlamydia trachomatis infection.
The aim of this study was to investigate the relationships between treatment outcomes of patients with urogenital Chlamydia trachomatis infections and minimum inhibitory concentrations (MICs) and drug resistance genes.. The clinical data of 92 patients diagnosed with Chlamydia trachomatis (C. trachomatis) infections were collected. Of these patients, 28 received regular treatment with azithromycin and 64 received minocycline. All patients underwent three monthly follow-ups after the completion of treatment. The microdilution method was used for the in vitro susceptibility tests. The acquisition of 23S rRNA mutations and presence of the tet(M) gene were detected by gene amplification and sequencing.. The MICs of azithromycin, clarithromycin, erythromycin, tetracycline, doxycycline, and minocycline were comparable for isolates from the treatment failure and treatment success groups. Higher detection rates of 23S rRNA gene mutations and tet(M) were found in the treatment failure group (57.14% and 71.43%, respectively) than in the treatment success group (14.29% and 30.23%, respectively) (p < 0.05). The A2057G, C2452A, and T2611C gene mutations of 23S rRNA were detected in eight clinical isolates from the azithromycin treatment failure group, while the T2611C gene mutation was detected in one clinical strain from the treatment success group.. The detection of resistance genes could better explain the high treatment failure rate than the MIC results in patients with urogenital C. trachomatis infections, highlighting the need for genetic antimicrobial resistance testing in infected patients.

Prevalence of genital Mycoplasma and response to eradication treatment in patients undergoing assisted reproductive techniques.
Several studies have reported greater success of fertilisation by ART in couples who were not infected by Ureaplasma. Increased semen quality and better results have also been observed in couples who were treated with antibiotics to eradicate the infection. The aim of this study was to determine the prevalence of genital mycoplasmas in urine samples from male partners enrolled in the Assisted Reproduction Program (ARP) in our healthcare area so that, positive cases can be treated prior to the use of ART in order to increase the quality of semen, improve the embryo implantation rates and minimize the risk of adverse effects during pregnancy.. This study included couples enrolled in the ARP during 2016. Mycoplasma detection was made using real-time PCR. In positive cases, both members of the couple were treated with antibiotics until eradication of the microorganism. The antibiotics used were: azithromycin, doxycycline, levofloxacin, moxifloxacin, and clindamycin.. Of the 205 men studied, 33 were positive: Ureaplasma urealyticum 15.1%, Mycoplasma hominis 3.9%. Eradication treatment with azithromycin failed in 50% compared to 10.2% for doxycycline. Of the 5 cases treated with levofloxacin, only 2 achieved elimination of U. urealyticum.. We consider that genital mycoplasma routine screening could be useful in order to increase the quality of semen which could simplify the in vitro fertilisation procedures and raise the success rate of embryo implantation and pregnancy, especially when fast, sensitive and specific technics as real time PCR are used.

Is it time to switch to doxycycline from azithromycin for treating genital chlamydial infections in women? Modelling the impact of autoinoculation from the gastrointestinal tract to the genital tract.
Single-dose azithromycin is recommended over multi-dose doxycycline as treatment for chlamydial infection. However, even with imperfect adherence, doxycycline is more effective in treating genital and rectal infection. Recently, it has been suggested that autoinoculation from the rectum to the genitals may be a source of persistent chlamydial infection in women. We estimated the impact autoinoculation may have on azithromycin and doxycycline effectiveness.. We estimate treatment effectiveness using a simple mathematical model, incorporating data on azithromycin and doxycycline efficacy from recent meta-analyses, and data on prevalence of rectal infection in women with genital chlamydial infection.. When the possibility of autoinoculation is taken into account, we calculate that doxycycline effectiveness may be 97% compared to just 82% for azithromycin.. Consideration should be given to re-evaluating azithromycin as the standard treatment for genital chlamydia in women.

Spontaneous resolution of genital Chlamydia trachomatis infection in women and protection from reinfection.
The natural history of chlamydia is variable and may include persisting asymptomatic infection, complications, or spontaneous resolution before treatment. Reinfection is common. We evaluated whether spontaneous resolution was associated with decreased reinfection in women returning for treatment of a positive chlamydia screening test. At enrollment, participants were tested for chlamydia, treated with azithromycin, and scheduled for a 6-month follow-up visit for repeat testing. Two hundred participants returned 1 to 12 months after treatment. Spontaneous resolution at enrollment was demonstrated in 44 (22.0%). Reinfection at follow-up occurred in 33 (16.5%), being more frequent in those with persisting infection at enrollment versus spontaneous resolution (31 of 156 [19.9%] vs 2 of 44 [4.5%]; P = .016). Adjusting for age, the odds of reinfection was 4 times higher for participants with persisting infection at enrollment (odds ratio 4.0, 95% confidence interval, 1.1-25.6; P = .034). Chlamydia treatment may attenuate protective immunity in some patients.

An observational cohort study of Chlamydia trachomatis treatment in pregnancy.
Currently, azithromycin is not considered a first-line treatment for Chlamydia trachomatis in pregnant women. We evaluated the use, efficacy, and safety of azithromycin compared with erythromycin and amoxicillin in the treatment of genital chlamydial infection during pregnancy.. This was a retrospective cohort study of pregnant women with genital chlamydial infection. Data on antibiotics prescribed, test-of-cure (TOC) results, and maternal and infant complications were collected from medical records.. Of the 277 women in the study sample, 69% were initially prescribed azithromycin, 9% amoxicillin, and 19% erythromycin. Eight-one percent of subjects had a TOC 7 or more days after diagnosis and before delivery. Treatment efficacy, as defined by a negative TOC, was 97% (95% confidence interval [CI], 92.9-99.2) for azithromycin, 95% (95% CI, 76.2-99.9) for amoxicillin, and 64% (95% CI, 44.1-81.4) for erythromycin. The efficacy of azithromycin was significantly higher than erythromycin (P < 0.0001). There were no significant differences in efficacy by age, race/ethnicity, concurrent sexually transmitted disease diagnosis, partner treatment, or substance use. Furthermore, there was no difference in complications for women or infants exposed to azithromycin compared with those treated with other regimens.. Clinical outcome data from this study population of women and infants support both efficacy and safety of azithromycin for treatment of C. trachomatis in pregnancy.

Should we offer antibiotic prophylaxis post sexual assault?
Our objective was to assess whether antibiotic prophylaxis should be offered to women post sexual assault by considering acceptability of prophylaxis, follow up attendance rates and the prevalence of sexually transmitted infections (STIs) in these women. Retrospective case notes review of female survivors of rape or sexual assault attending the Rose Clinic, Ambrose King Centre, Royal London Hospital between 1 January 1997 and 31 May 1999 was carried out. The following selection criteria were applied: age greater than 16 years; attending within two weeks of assault; having experienced vaginal and/or anal penetration. All women were screened for STI using standard investigation methods detailed below. Antibiotic prophylaxis was offered within two weeks of the assault, the antibiotic regimens used as recommended. The women were invited to attend for results at two weeks and offered a further screen at three months post assault. Bacterial vaginosis was present in 32% of the women screened, Chlamydia trachomatis was identified in 8%, none tested positive for Neisseria gonorrhoeae. Of the 25 women who were offered antibiotic prophylaxis, 88% accepted. Follow up attendances were 57% at two weeks and 30% at three months. Antibiotic prophylaxis was acceptable to women. Among recent rape victims, follow-up rates are low confirmed by our study. These factors support the use of antibiotic prophylaxis post sexual assault. There was an apparently high prevalence of STIs amongst women in this study. More research is required with respect to this aspect of the work and to consider the cost-benefit analysis of antibiotic prophylaxis.

Tetracycline treatment does not eradicate Mycoplasma genitalium.
To study the treatment efficacy of tetracyclines and azithromycin in Mycoplasma genitalium positive patients attending an STD clinic.. All M genitalium positive patients (34 men and 26 women) attending an STD clinic during a 6 month period were treated with antibiotics. All patients known to be partners of M genitalium positive patients and those who were M genitalium positive, but not initially treated, were treated with azithromycin. Patients with urethritis and/or cervicitis were treated with tetracyclines before their M genitalium status was known.. 10 of 14 women (71%) and 10 of 16 men (63%) treated with tetracyclines were M genitalium positive at follow up, whereas all patients treated with azithromycin (16 men and 20 women) were M genitalium negative, at the 4 week follow up visit.. These results suggest that tetracyclines are not sufficient to eradicate M genitalium. Randomised controlled treatment trials are urgently needed.

[A new therapeutic approach in the treatment of genital chlamydial infections. Azithromycin (Sumamed)].
Azithromycin is a member of a new class of macrolides called azalydes. Although azithromycin resembles erythromycine there are significant differences in antibacterial activity and pharmacokinetic profile. Azithromycin is taken up by cells and the intracellular concentrations are significantly higher than serum concentrations. After a single oral dose of Ig, azithromycin has a long lasting effect--the tissue concentrations in the uterine and cervical tissues are kept above the minimal inhibitory concentration for Chlamydia trachomatis for more than 10 days. In order to achieve the maximal bioavailability and avoid side effects (gastrointestinal discomfort), azithromycin should be taken apart from meals (one hour before or two hours after meals). Azithromycin has no hepatotoxic potential and the possibility for drug interactions is not apparent. It is also recommended for use in pregnant women--FDA category B. A single oral dose of Ig azithromycin is the reasonable choice for the treatment of uncomplicated genital chlamydial infection.

Doxycycline compared with azithromycin for treating women with genital Chlamydia trachomatis infections: an incremental cost-effectiveness analysis.
To compare the economic consequences of doxycycline therapy with those of azithromycin therapy for women with uncomplicated cervical chlamydial infections.. Decision analysis in which the health outcomes, costs, and cost-effectiveness of two provider-administered treatment strategies for women with uncomplicated cervical chlamydial infections were compared: 1) initial therapy with doxycycline, 100 mg orally twice daily for 7 days (estimated cost, $5.51) and 2) initial therapy with azithromycin, 1 g orally administered as a single dose (estimated cost, $18.75).. Under baseline assumptions, the azithromycin strategy incurred fewer major and minor complications and was less expensive overall than the doxycycline strategy despite a higher initial cost for acquiring antibiotic agents. In univariate sensitivity analyses, the azithromycin strategy prevented more major complications but was more expensive than the doxycycline strategy when doxycycline effectiveness was greater than 0.93. In a multivariate sensitivity analysis combining 11 parameter estimates selected so that the cost-effectiveness of the doxycycline strategy would be maximized relative to that of the azithromycin strategy, the azithromycin strategy resulted in fewer complications but was more costly. The incremental cost-effectiveness was $521 per additional major complication prevented. However, if the difference in the cost of azithromycin and doxycycline decreased to $9.80, the azithromycin strategy was less expensive and more effective, even under these extreme conditions.. On the basis of the best available data as derived from the literature and experts, the azithromycin strategy was more cost-effective than the doxycycline strategy for women with uncomplicated cervical chlamydial infections. Despite the dominance of the azithromycin strategy over the doxycycline strategy, the adoption of the azithromycin strategy may be limited by the practical financial constraints of our currently fragmented health care system, in which the costs and benefits of preventing chlamydia sequelae are often incurred by different components of the system.

Characteristics of murine model of genital infection with Chlamydia trachomatis and effects of therapy with tetracyclines, amoxicillin-clavulanic acid, or azithromycin.
Following intravaginal inoculation of progesterone-treated outbred mice with Chlamydia trachomatis MoPn, 4 to 6 log10 inclusion-forming units were recovered in vaginal swabs for 21 days but all animals were culture negative after 28 days. Serum antibody titers were elevated and remained high for at least 70 days. Between 28 and 70 days, upper tract infection (inflammation and distension of the uterine horns, occlusion of oviducts with inflammatory exudate, pyosalpinx, and hydrosalpinx) was seen in > 80% of the animals. Mice were dosed orally, commencing at 7 days after infection, with minocycline, doxycycline, or amoxicillin-clavulanate. Further groups received azithromycin either as a single high dose or as lower once-daily doses. In addition, minocycline and amoxicillin-clavulanate were administered at 24 h after infection, and this early treatment prevented elevation of antibody titers whereas delayed therapy did not. Vaginal swabs from mice in all treatment regimens were culture negative except for 25% of mice receiving either early amoxicillin-clavulanate or low-dose azithromycin, which yielded low numbers (20 to 70 inclusion-forming units) of chlamydiae. Numbers of fertile mice in the early treatment regimens and their litter sizes were similar to those of noninfected controls, although 25% of amoxicillin-clavulanate-treated mice had unilateral hydrosalpinges. In comparison, 88% of untreated mice developed hydrosalpinges and only 25% conceived. Delayed dosing did not affect the outcome of amoxicillin-clavulanate therapy but did diminish the protective efficacy of minocycline such that 50% of treated mice had either unilateral hydrosalpinges or ovarian abscesses. Doxycycline and azithromycin were highly effective in restoring fertility. This model makes possible the study of both short- and long-term outcomes of chlamydial infection.
