Effect of 12-week of aerobic exercise on hormones and lipid profile status in adolescent girls with polycystic ovary syndrome: A study during COVID-19.
COVID-19 as a viral disease has brought up the need to exercise more than before due to its physiological effects on health. Therefore, this study investigates the effect of 12-week of aerobic exercise on female students' hormone levels and lipid profile with polycystic ovary syndrome (PCOS) during the COVID-19 pandemic.. Using a 12-week quasi-experimental with pretest, posttest research design among 40 Iranian female students aged 18-14 with PCOS, we randomly allocated the participants to either an experimental (they performed aerobic exercises three 60-minute sessions per week at home using content production) or a control condition. Their anthropometric and blood samples (e.g., testosterone, estrogen, prolactin, and lipid profile) were taken in two stages before and after the training protocol.. Findings demonstrated that performing aerobic exercises is an effective and non-invasive method that could have a positive effect on young girls' PCOS during COVID-19 pandemic.. La pandémie de COVID-19, en tant que maladie virale, a fait ressortir la nécessité de faire de l’exercice plus que jamais en raison de ses effets physiologiques sur la santé. Par conséquent, cette étude examine l’effet de 12 semaines d’exercice aérobique sur les niveaux hormonaux et le profil lipidique d’étudiantes atteintes du syndrome d’ovaires polykystiques (SOPK) pendant la pandémie de COVID-19.. En utilisant un modèle de recherche quasi-expérimental de 12 semaines avec pré-test, post-test auprès de 40 étudiantes iraniennes âgées de 18 à 14 ans atteintes du SOPK, nous avons réparti au hasard les participantes entre une série expérimentale (elles ont effectué des exercices aérobiques à raison de trois séances de 60 minutes par semaine à la maison) et une série contrôle. Les échantillons anthropométriques et sanguins (testostérone, œstrogène, prolactine et profil lipidique) ont été prélevés en deux étapes, avant et après le protocole d’entraînement.. Les résultats ont démontré que la pratique d’exercices d’aérobic est une méthode efficace et non invasive qui pourrait avoir un effet positif sur le SOPK des jeunes filles pendant la pandémie de COVID-19.. Our research showed that even less than 5 GBq irradiation could induce a transient testicular dysfunction in the first 3 months of therapy, but it was mostly reversible after 12 months.. The online version contains supplementary material available at 10.1007/s13204-023-02822-5.. Embelin is predicted to have a high probability of immunotoxicity potential and affect drug metabolism by inhibiting CYP2D6. In addition, it affects food intake, weight gain, and the number of implantations in pregnant rats. Therefore, it is highly recommended not to take embelin and embelin-rich plants during pregnancy.

This study ascribes for a new immunomodulatory role for IL11 during tumor development that is amenable to anti-cytokine based therapy of colon cancer.. Inflammation response do not seem to be enough to explain all the Essure-related adverse outcomes, suggesting the involvement of other biological mechanisms.. NCT03281564.. Inflammation and fibrosis are found in the surrounding tubal tissue around the Essure. Adult patients with BED with co-occurring obesity who have good responses to acute treatment with naltrexone/bupropion should be offered maintenance treatment with naltrexone/bupropion.. dp/dtmax in PiCCO parameter can be used as a bedside indicator to evaluate cardiac function in SIC patients due to its simplicity and ease of operation. Esmolol control of heart rate in SIC patients can improve cardiac function and reduce short-term mortality.. Inverted microscopy showed that compared with the NC group, the OGD/R group had poor cell status, swollen cytosol, visible cell lysis fragments and significantly lower cell activity [(49.1±2.7)% vs. (100.0±9.7)%, P < 0.01]; compared with the OGD/R group, the HW group had improved cell status and remarkably higher cell activity [(63.3±1.8)% vs. (49.1±2.7)%, P < 0.01]. Transmission electron microscopy showed that the neuronal nuclear membrane of cells in the OGD/R group was lysed and a higher number of autophagic lysosomes were visible compared with the NC group; compared with the OGD/R group, the neuronal damage of cells in the HW group was reduced and the number of autophagic lysosomes was notably decreased. The results of immunofluorescence assay showed that the expressions of LC3 and Beclin-1 were outstandingly enhanced in the OGD/R group compared with the NC group, and the expressions of LC3 and Beclin-1 were markedly weakened in the HW group compared with the OGD/R group. Western blotting assay showed that the expressions were prominently higher in both LC3II/I and Beclin-1 in the OGD/R group compared with the NC group (LC3II/I: 1.44±0.05 vs. 0.37±0.03, Beclin-1/β-actin: 1.00±0.02 vs. 0.64±0.01, both P < 0.01); compared with the OGD/R group, the protein expression of both LC3II/I and Beclin-1 in the HW group cells were notably lower (LC3II/I: 0.54±0.02 vs. 1.44±0.05, Beclin-1/β-actin: 0.83±0.07 vs. 1.00±0.02, both P < 0.01).. Hydrogen-rich water has a significant protective effect on OGD/R-causing HT22 cell injury, and the mechanism may be related to the inhibition of autophagy.. The prevalence of delirium in ICU patients is over 50%, with hypoactive delirium being the most common. Age, APACHE score at ICU admission, neurological disease, sepsis and duration of mechanical ventilation were all independent risk factors for the development of delirium in ICU patients. More than half of patients with delirium were still delirious when they discharged from the ICU.. For individuals ≥75 years, plasma Aβ42 and P-tau181 might not be associated with cognitive impairment, and MRI parameters, including PVWMH, LVBI and cortical atrophy, are related to CI. The cognitive statuses of people over 75 years old were used as the endpoint event in this study. Therefore, it can be considered that these MRI markers might have more important clinical significance for early assessment and dynamic observation, but more studies are still needed to verify this hypothesis.. We recommend using the Art/Zn complex owing to its moderate inhibitory and antiviral effects against the SARS-CoV-2 with a low cytotoxic effect on host (Vero E6) cells. We suggest conducting further prospective studies to investigate the biological effects of Art/Zn in animal models at different concentrations for testing its clinical efficacy and safety in inhibiting SARS-CoV-2 activities.. The R/T sequence resulted in a significantly longer OS and PFS and improved disease control compared with the reverse sequence. R and T given not sequentially have similar impacts on survival. More data are needed to define the best sequence and to explore the efficacy of sequential (T/R or R/T) treatment combined with molecular-targeted drugs.

Comparative study of cefepime versus ceftazidime in the empiric treatment of pediatric cancer patients with fever and neutropenia.
In view of the recent trend toward monotherapy in the treatment of bacterial infection, we evaluate the clinical efficacy and safety of cefepime vs. ceftazidime for the empiric treatment of febrile episodes in neutropenic pediatric cancer patients.. In a single site, open label study, 104 neutropenic pediatric cancer patients [96% with absolute neutrophil count (ANC) of <500 neutrophils/mm3] with a median age of 6 years were randomized (1:1) to receive either intravenous cefepime or ceftazidime (50 mg/kg/dose every 8 h; < or = 6 g/day) for empiric treatment of fever (temperature >38.0 degrees C occurring at least twice in 24 h, or single >38.5 degrees C). Febrile episodes were classified as either microbiologically or clinically documented infection or fever of unknown origin. Therapy continued until the ANC was > or = 1,000 neutrophils/mm3 or there was an increasing ANC in low risk patients (maximum duration of treatment, 8 weeks). The primary efficacy endpoints assessed were clinical and microbiologic response to assigned drug therapy. Secondary outcome measures were rate of early discontinuation of study drug and use of concomitant antibiotic therapy to modify initial study drug regimen.. Of 68 patients who could be evaluated for efficacy, 74% (26 of 35) of cefepime-treated patients and 70% (23 of 33) of ceftazidime-treated patients responded to treatment. The small number of study patients precluded statistical analysis of results. In a modified intent-to-treat analysis, 59% of the patients treated with cefepime and 47% of ceftazidime-treated patients responded to therapy. Cefepime patients developed fewer new infections than ceftazidime patients (9% vs. 21%, respectively) and early discontinuation of study drug therapy occurred slightly more often in the ceftazidime group. Further, the use of concomitant systemic antimicrobial therapy (mostly vancomycin) occurred less often in the cefepime-treated patients, as compared with the ceftazidime group [35% [17 of 49] vs. 44% (24 of 55), respectively]. No deaths or serious adverse events were considered to be related to study therapy. The most frequent adverse event was rash that was moderate in severity, and it occurred equally in both groups.. Cefepime appears to be safe and effective compared with ceftazidime for initial empiric therapy of febrile episodes in neutropenic pediatric cancer patients.

Cefepime vs. cefoperazone/sulbactam in combination with amikacin as empirical antibiotic therapy in febrile neutropenia.
Beta lactams are standard empirical therapy for febrile neutropenia (FN). The aim of this study was to evaluate the efficacy and safety of cefepime monotherapy compared with cefoperazone/sulbactam plus amikacin (CS + A) for empirical treatment of high risk FN.. One hundred seventy-five patients with 336 FN episodes were randomized to receive either cefepime (2 g q8h for adults and 50 mg/kg q8h for children) or CS (2 g q8h for adults and 50 mg/kg q8h for children) plus amikacin (15 mg/kg once a day). Positive response was defined as afebrile within 72 h of starting antibiotics, persistent afebrile status more than 48 h and no requirement of second-line antibiotics and antifungal agents.. Three hundred thirty-six episodes were assessable for efficacy (168 cefepime, 168 CS + A). The positive response to antibiotics was identical for cefepime (53%) and CS + A (53%). Positive response was similar in MDI (microbiologically documented infection), 50 vs. 35% (p = 0.248), CDI (clinically documented infection), 50 vs. 35% (p = 0.259), combination CDI + MDI, 25 vs. 15% (p = 0.400), FUO (fever of unknown origin), 68 vs. 72% (p = 0.577) respectively in the two groups. The successful discontinuation of antibiotics at 72 h in FUO was similar in both groups (60 vs. 59%, p = 0.544). Total drug-related adverse events were similar in both groups (8 vs. 6%) except renal dysfunction was high in CS + A (1 vs. 7 events). Mortality was the same between two groups (8 vs 7%).. Cefepime monotherapy and CS + A had similar efficacy as first-line therapy for FN. Discontinuation of empirical antibiotics is safe and feasible approach in selected group of FUO patients.

Outpatient versus inpatient IV antibiotic management for pediatric oncology patients with low risk febrile neutropenia: a randomised trial.
Febrile neutropenia (FN) is a frequent, serious complication of intensive pediatric chemotherapy regimens. The aim of this trial was to compare quality of life (QOL) between inpatient and outpatient intravenous antibiotic management of children and adolescents with low risk febrile neutropenia (LRFN).. In this randomised non-blinded trial, patients between 1 and 21 years old, receiving low/moderate intensity chemotherapy were pre-consented and, on presentation to emergency (ED) with FN satisfying low risk criteria, randomised to either outpatient or inpatient care with intravenous cefepime 50 mg/kg (12 hourly). All patients continued antibiotics for at least 48 hours, until afebrile for 24 hours and demonstrating a rising absolute neutrophil count ≥200/mm(3). Several domains of QOL were examined by daily questionnaire.. Eighty-one patients presented to ED with 159 episodes of fever. Thirty-seven FN presentations involving 27 patients were randomised to inpatient (18) and outpatient (19) management. Combined QOL mean scores for parents were higher for the outpatient group and scores for three specific parent variables (keeping up with household tasks/time spent with partner/time spent with other children) were higher among outpatients. There was no difference in parent confidence/satisfaction in care between groups. Patients scored better in the outpatient group overall and for sleep and appetite. The mean length of fever was equivalent between groups and there were no serious adverse events attributable to cefepime or outpatient care.. Outpatient cefepime management of LRFN provided significant benefit to parents and patients across several QOL domains and appeared both feasible and safe.

A randomized trial of cefozopran versus cefepime as empirical antibiotic treatment of febrile neutropenia in pediatric cancer patients.
Febrile neutropenia (FN) is a common and serious complication of cancer chemotherapy associated with significant morbidity and mortality. Cefozopran (CZOP) is a potential candidate for empirical monotherapy in FN. However, studies on the use of CZOP as empirical treatment for pediatric patients with FN are quite limited. The purpose of this study was to compare the efficacy and safety of CZOP with cefepime (CFPM) empirical monotherapy in pediatric cancer patients with FN.. A total of 64 patients with 224 episodes of FN were randomly assigned to receive antibiotic therapy with either CZOP (100 mg/kg/day) or CFPM (100 mg/kg/day). Of these episodes, 223 were considered eligible for the study. Success was defined as resolution of febrile episodes and clinical signs of infection within 120 hr following the start of antibiotic therapy.. The success rate was not significantly different between the CZOP (64.0%) and CFPM (56.3%) groups (P = 0.275). Duration of fever, duration of antibiotic therapy, and the success rate in patients with blood stream infection did not differ between the two groups. There was no infection-related mortality in the study period.. Both CZOP and CFPM as monotherapy appear to be effective and safe in pediatric patients. This study suggests that CZOP has satisfactory efficacy and is well tolerated as initial empirical therapy for pediatric cancer patients with FN.

Panipenem versus cefepime as empirical monotherapy in adult cancer patients with febrile neutropenia: a prospective randomized trial.
To compare the efficacy and safety of panipenem/betamipron with cefepime as empirical monotherapy for adult cancer patients with febrile neutropenia, a randomized, open-label, comparative trial was performed.. All enrolled patients were randomly assigned to receive either panipenem or cefepime. All febrile episodes were classified as microbiologically defined infection (MDI), clinically defined infection (CDI) or unexplained fever (UF). Clinical responses to antibiotic therapy were defined as success, initial response but regimen modified or failure.. A total of 116 patients were enrolled: 55 patients in the panipenem group and 61 patients in the cefepime group. Demographic and clinical characteristics were similar in the two groups (P > 0.05). In the final evaluation, the success rate for the panipenem group (89.1%) was similar to that of the cefepime group (91.8%) (non-inferiority, P = 0.002, 95% confidence interval: -13.48%, 10.35%). Of the 18 bacterial isolates, nine (50%) were gram-positive and nine (50%) were gram-negative. The prevalence of adverse events in the panipenem group (23.6%) were similar to those in the cefepime group (23.0%) (P = 0.93). All of the adverse events were well tolerated and transient.. Although larger studies are necessary, panipenem appeared to be as effective and safe as cefepime for empirical monotherapy in the treatment of adult cancer patients with febrile neutropenia.

Cefepime plus amikacin as an initial empirical therapy of febrile neutropenia in paediatric cancer patients.
We evaluated the efficacy of cefepime in association with amikacin in the initial empirical therapy of febrile neutropenic children.. The study was an open-labelled, non-randomised prospective trial to assess the efficacy and safety of this association, from January 2003 to December 2003. Children and adolescents were treated for a haematological malignancy or a primary, refractory or relapsed solid tumour, and presented with febrile neutropenia. Patients received cefepime (50 mg per kg per dose every 8 hours for children weighing less than or equal to 40 kg; and 2 g every 8 hours for those weighing more than 40 kg) plus a single daily dose of amikacin at 15 mg per kg per day, up to a maximum 250 mg. If fever persisted, a second-line therapy with carbapenem was administered. Amphotericin B was added at 96 hours if fever and neutropenia persisted.. 103 episodes of fever and neutropenia were evaluated in 54 patients. 18.4 percent of the episodes were microbiologically-documented infections, 24.3 percent were clinically documented, and 57.3 percent were episodes with unexplained fever. 54.4 percent of the episodes responded to cefepime plus amikacin without a need for treatment modification. A higher success rate (74.6 percent) was observed in episodes with unexplained fever. In all cases of persistent fever, the antibiotics were changed to carbapenem within 72 hours and all patients survived. One patient died because of culture-negative septic shock within 24 hours of admission. A mild gastrointestinal intolerance occurred in three patients.. This study suggests that cefepime plus amikacin presents a satisfactory efficacy and a good tolerance as an initial empirical therapy for febrile neutropenic children.

Cefepime monotherapy for treatment of febrile neutropenia in children.
Empirical therapy for children with febrile neutropenia has traditionally consisted of combination antibiotics, usually a beta-lactam and an aminoglycoside. However, recent trends and international guidelines have now made monotherapy a feasible option in the management of this group of patients. We prospectively evaluated the efficacy and safety of cefepime monotherapy in our population of paediatric cancer patients with febrile neutropenia.. An audit was performed on children aged 16 years and younger presenting with fever and neutropenia who were managed with empirical single-agent cefepime. The patients were analysed for clinical outcome, documented infections and side-effects of the study drug. Success was defined as clinical improvement without treatment modification. Death or any change to the empirical antibiotic was considered as failure.. In this study 79 children (median age 5.2 years) with 133 episodes of febrile neutropenia were prospectively studied between August 2004 and August 2005. A microbiologically documented infection was seen in 26 episodes. The success rate of cefepime monotherapy was 60%. The rate of survival through neutropenia (with or without modification) was 98%. No significant adverse effects were seen.. Cefepime monotherapy is a safe and feasible option for treatment of childhood cancer patients with febrile neutropenia.

Randomized study of cefepime versus ceftazidime plus amikacin in patients with solid tumors treated with high dose chemotherapy (HDC) and peripheral blood stem cell support (PBSCS) with febrile neutropenia.
This randomized clinical trial evaluated the efficacy and safety of monotherapy with cefepime for patients with solid tumors treated with high dose chemotherapy (HDC) and peripheral blood stem cell support (PBSCS) with febrile neutropenia.. Patients with solid tumors treated with HDC and PBSCS, that developed fever and neutropenia (absolute neutrophil count < 500 cells/microL) were eligible, and randomly assigned to receive ceftazidime plus amikacin or cefepime.. Fifty-one episodes were randomized, and all were evaluable (27 received ceftazidime plus amikacin arm, and 24 cefepime). Major efficacy endpoints did not show significant differences, with success rates of 44.4% and 54.2% (p = 0.481) for the combination arm and the monotherapy arm, respectively. The proportion of patients that became afebrile in the first 24 hours was significantly higher in the cefepime group (41.7% vs 11.1%, respectively; p = 0.012). However, due to its premature closure and small sample size, this study lacks the adequate power to definitely address this question.. Cefepime monotherapy appeared to have an equivalent efficacy and safety as empiric treatment in febrile neutropenia episodes in a highrisk population compared with ceftazidime and amikacin. Nevertheless, this study is not adequately powered to answer this question. Given the small number of patients randomized and the single-center nature of this study, these results must be cautiously interpreted.

Cefepime versus ticarcillin and clavulanate potassium and aztreonam for febrile neutropenia therapy in high-dose chemotherapy patients.
An open labeled randomized trial comparing the efficacy and cost of empirically applied cefepime (C) as monotherapy versus combination therapy consisting of ticarcillin and clavulanate potassium and aztreonam (T/A) was performed in febrile neutropenic patients following high-dose chemotherapy (HDC) +/- radiation, with or without peripheral blood stem cell support. Over a 28-month period, 126 patients were screened and included in the study. Using afebrile status following 3 days of therapy as a primary endpoint, both regimens produced comparable clinical response rates (C = 55% vs. T/A = 61%). Also, the use of vancomycin for resistant gram-positive infections and alteration of gram-negative infection coverage was similar in both groups (C = 40% vs. T/A = 47% and C = 29% vs. T/A = 24%). Both treatment groups had similar needs for empirical antifungal therapy (C = 25% vs. T/A = 22%). There was a postrandomization difference between the two groups in that the "C" group had a significantly higher number of allogeneic transplants and non-stem-cell-supported patients, whereas the "T/A" group had a significantly greater number of autologous peripheral blood stem cell patients (p < 0.0001). Despite this difference, the C group had a significantly lower cost ratio than the T/A group (p = 0.016). In conclusion, we have shown that C treatment of febrile neutropenic patients following HDC results in similar efficacy and lower cost when compared to T/A, despite the inclusion of higher risk patients in the C group.

Treatment of febrile neutropenic patients with cancer who require hospitalization: a prospective randomized study comparing imipenem and cefepime.
The objective of the current study was to compare the efficacy and safety of imipenem and cefepime in the treatment of adult patients with cancer who had fever and neutropenia requiring hospitalization according to Infectious Disease Society of America criteria.. In the current prospective randomized clinical trial at a university-affiliated tertiary cancer center, adult patients with cancer who had fever (> or = 38.3 degrees C or > or = 38.0 degrees C for > 2 hours) and neutropenia (< or = 500/mm(3) or < 1000/mm(3) but declining) requiring hospitalization were randomized to receive either cefepime or imipenem. Vancomycin or amikacin was added on suspicion of gram-positive or gram-negative bacterial infection, respectively.. Patients who received an imipenem regimen or a cefepime regimen were comparable in terms of age, gender, underlying malignancy, prior transplantation, degree and trend of neutropenia, and presence of central venous catheters (P > or = 0.3). An intent-to-treat analysis showed a 68% response rate to the imipenem regimen, compared with a 75% response rate to the cefepime regimen (P = 0.2). The rates of antibiotic-related adverse events and superinfections also were comparable (P = 0.6). There was no difference in response among patients who received imipenem or cefepime alone compared with patients who also received vancomycin or amikacin (P = 1.0). Leukemia was the only independent risk factor associated with a poor outcome (odds ratio, 4.6; 95% confidence interval, 1.9-10.7; P < 0.0001).. Imipenem and cefepime had similar efficacy and safety profiles in the treatment of adult cancer patients with fever and neutropenia who required hospitalization. The addition of either vancomycin or amikacin may not be necessary.

Cefepime monotherapy as an empirical initial treatment of patients with febrile neutropenia.
Currently, monotherapy is considered a valid alternative to the combination antibiotic treatments used for initial, empirical management of febrile neutropenia. The advent of new cephalosporins warrants assessment. The aim of this study was to prospectively evaluate the effectiveness of cefepime monotherapy in the treatment of cancer patients with febrile granulocytopenia (< 1000 leukocytes/muL and/or < 500 neutrophils/muL). A prospective, multicenter, nonrandomized trial was conducted. Initial treatment consisted of iv cefepime, 2 g every 8 h. If the patient was still febrile after 72 h, amikacin, vancomycin/teicoplanin, and amphotericin B were added sequentially. Response was evaluated according to EORTC criteria. One hundred twenty episodes were analyzed in 81 males and 39 females (median age, 52 yr; range, 15-83). The median leukocyte count at the time of diagnosis was 781 microL(-1) (range, 100-2600) and the median neutrophil count was 173 microL(-1) (range 0-500). The median duration of neutropenia (< 1000 neutrophils/microL) was 4.8 d (range, 3-20). Fifty-two episodes (44%) were confirmed microbiologically (42 presented as bacteremia), 31 with Gram-positive bacteria and 21 with Gram-negative bacteria, 47 (39.3%) were confirmed clinically, 16 (13.3%) were considered as probable infections, and 5 (4.2%) as doubtful infections. Protocol success was achieved in 110 episodes (91.7%), 8 (6.6%) were treatment failures, and 2 (1.7%) were not evaluable. Ninety-nine episodes (83.3%) were controlled with cefepime monotherapy, with 19 other episodes requiring additional antibiotics: amikacin in 7 (5.8%), amikacin + vancomycin/teicoplanin in 12 (10.1%). Three patients (2,5%) died during an episode of neutropenic fever. Cefepime is effective as an initial, empirical treatment of febrile neutropenia. The early addition of amikacin and/or vancomycin resolves most of the monotherapy failures, which seem somewhat lower than with other monotherapies.

Cefepime versus ceftazidime as empiric monotherapy for fever and neutropenia in children with cancer.
Monotherapy with cefepime or ceftazidime is an effective alternative to combination therapy for the treatment of febrile neutropenic adult cancer patients. We compared the efficacy and safety of cefepime and ceftazidime as empiric monotherapy of febrile neutropenia in children with cancer.. A prospective, open label, randomized, comparative study in pediatric cancer patients was conducted at Chang Gung Children's Hospital from January 1, 2000, to April 15, 2001. Patients with fever and neutropenia (absolute neutrophil count of < or = 500/mm3) were randomized to receive either intravenous cefepime or ceftazidime (50 mg/kg/dose as two or three doses daily). Febrile episodes were classified as microbiologically documented infection, clinically documented infection or unexplained fever. Clinical response to therapy was classified as success and failure.. Ninety-five pediatric cancer patients with 120 febrile neutropenic episodes were randomized to receive empiric treatment with cefepime or ceftazidime. After 72 h of treatment, 82.8% (48 of 58) of the eligible patients in the cefepime group continued with unmodified therapy, compared with 87.9% (51 of 58) in the ceftazidime group. The neutrophil count was <100/mm3 at randomization for 76% of the patients in the cefepime group and 83% of those in the ceftazidime group; the median durations of neutropenia (<500/mm3) were 8.5 and 6.5 days, respectively. Of the 96 evaluable episodes the overall success rate with unmodified empiric therapy until the end of the treatment course in the cefepime group was comparable with that in the ceftazidime group (69% vs. 71%, P = 0.95). The response rate after glycopeptides were added to the regimens was 79.2% for the cefepime group and 77.1% for the ceftazidime group. The bacterial eradication rate was 33% for the cefepime group and 20% for the ceftazidime group (P = 0.85), and the rates of new infections were 10.4% vs. 4.2% (P = 0.67), respectively. Both study drugs were well-tolerated. Three (6.4%) patients in the cefepime group and 2 (4.3%) patients in the ceftazidime group died.. Cefepime appeared to be as effective and safe as ceftazidime for empiric treatment of febrile episodes in neutropenic pediatric cancer patients.

Randomized comparison of cefepime versus ceftazidime monotherapy for fever and neutropenia in children with solid tumors.
With the availability of new broad-spectrum antibiotics, initial therapy with a single agent has become an alternative to classic combinations, especially beta-lactam antibiotics plus aminoglycosides, in the management of febrile neutropenic cancer patients.. Since January 1994, monotherapy has been used for empiric initial treatment at our center. The aim of this prospective randomized study is to compare the efficacy of cefepime (CFP), a new fourth-generation cephalosporin, and ceftazidime (CFZ) as empirical monotherapy of febrile neutropenic patients with solid tumors. From January 1998 to November 1998, 63 episodes of fever and neutropenia occurring in 33 children with solid tumors including lymphomas, were randomized to receive treatment with either CFP or CFZ. The patients were analyzed for leukocyte count and absolute neutrophil count (ANC) at entry, days in fever, neutropenia and hospitalization, and side effects of drugs. Success with or without modifications of the initial antibiotic was defined as survival through neutropenia; failure was death due to infection.. In our study group, with a median age of 7 [(1/12)-14] years, CFP was administered in 32, and CFZ in 31 episodes. An infection was documented microbiologically in eight episodes (25%) in the CFP arm and in nine episodes (29%) in the CFZ arm. The success rate with initial empiric monotherapy was 62.5% in the CFP arm and 61.3% in the CFZ arm respectively (P > 0.05). The total success rate (success with or without modification) was 100% in both arms. No major adverse effects were observed in either groups.. CFP is as effective and safe as CFZ for the empirical treatment of febrile episodes in neutropenic patients with solid tumors.

Comparative study of cefepime versus ceftazidime in the empiric treatment of pediatric cancer patients with fever and neutropenia.
In view of the recent trend toward monotherapy in the treatment of bacterial infection, we evaluate the clinical efficacy and safety of cefepime vs. ceftazidime for the empiric treatment of febrile episodes in neutropenic pediatric cancer patients.. In a single site, open label study, 104 neutropenic pediatric cancer patients [96% with absolute neutrophil count (ANC) of <500 neutrophils/mm3] with a median age of 6 years were randomized (1:1) to receive either intravenous cefepime or ceftazidime (50 mg/kg/dose every 8 h; < or = 6 g/day) for empiric treatment of fever (temperature >38.0 degrees C occurring at least twice in 24 h, or single >38.5 degrees C). Febrile episodes were classified as either microbiologically or clinically documented infection or fever of unknown origin. Therapy continued until the ANC was > or = 1,000 neutrophils/mm3 or there was an increasing ANC in low risk patients (maximum duration of treatment, 8 weeks). The primary efficacy endpoints assessed were clinical and microbiologic response to assigned drug therapy. Secondary outcome measures were rate of early discontinuation of study drug and use of concomitant antibiotic therapy to modify initial study drug regimen.. Of 68 patients who could be evaluated for efficacy, 74% (26 of 35) of cefepime-treated patients and 70% (23 of 33) of ceftazidime-treated patients responded to treatment. The small number of study patients precluded statistical analysis of results. In a modified intent-to-treat analysis, 59% of the patients treated with cefepime and 47% of ceftazidime-treated patients responded to therapy. Cefepime patients developed fewer new infections than ceftazidime patients (9% vs. 21%, respectively) and early discontinuation of study drug therapy occurred slightly more often in the ceftazidime group. Further, the use of concomitant systemic antimicrobial therapy (mostly vancomycin) occurred less often in the cefepime-treated patients, as compared with the ceftazidime group [35% [17 of 49] vs. 44% (24 of 55), respectively]. No deaths or serious adverse events were considered to be related to study therapy. The most frequent adverse event was rash that was moderate in severity, and it occurred equally in both groups.. Cefepime appears to be safe and effective compared with ceftazidime for initial empiric therapy of febrile episodes in neutropenic pediatric cancer patients.

Cost-effectiveness of cefepime + netilmicin or ceftazidime + amikacin or meropenem monotherapy in febrile neutropenic children with malignancy in Turkey.
Infection remains the major cause of morbidity and mortality in immunocompromised children with malignancy. In addition, the economic impact of antibiotic treatment should always be evaluated, especially in developing countries. In our center between January 1998 and January 1999, 73 children with hematological malignancies [acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML)]; 9 children with solid tumors (rhabdomyosarcoma, neuroblastoma) had 87 febrile neutropenic episodes (related to chemotherapy). These children were randomized prospectively into three treatment groups. The first group (n: 28) received cefepime plus netilmicin, while the second group (n: 29) was treated with ceftazidime plus amikacin and the third (n: 30) with meropenem as monotherapy. The aim of the study was to compare the success rates and cost of fourth generation cephalosporin plus aminoglycoside and monotherapy of meropenem with ceftazidime plus amikacin, which is the standard therapy for febrile neutropenia. Microbiologically documented infections were 29.9%, clinically documented infections were 9.2% and 60.9% of the febrile neutropenic episodes were considered to be FUO. Gram-positive microorganisms were the most commonly isolated agents from blood cultures [MRSA (Methicillin Resistant Staphylococcus aureus) in 6 patients and MSSA (Methicillin Sensitive Staphylococcus aureus) in 4 patients]. The success rates were 78.5%, 79.3% and 73.3 % for the 1st, 2nd and 3rd groups respectively. In 4 patients (4.5%) fever responded only to amphotericin-B therapy. There was no statistically significant difference between the three treatment regimens with respect to efficacy, safety and tolerance (chi2 test, p>0.05), but while the third and fourth generation cephalosporins + aminoglycosides were comparable for cost, the monotherapy regimen was the most expensive. The main determining factors for the choice of treatment of febrile neutropenic children, especially in a developing country, are cost, presence of indwelling catheter and the bacterial flora of the unit, as well as efficacy.

Cefepime versus ceftazidime as empiric therapy for fever in neutropenic patients with cancer.
To compare the efficacies of cefepime and ceftazidime as empiric therapy during the management of fever in cancer patients with chemotherapy-induced neutropenia.. A prospective, double-blind, randomized study of cefepime 2 g every eight hours and ceftazidime 2 g every eight hours was performed in 276 adult neutropenic (absolute neutrophil count < 500/mm3) cancer patients with fever.. Median duration of neutropenia was five days. Sixty-one percent (n = 188) of the patients were evaluable. Treatment was successful in 57% (58/101) of cefepime-treated patients and 60% (52/87) of ceftazidime-treated patients (95% CI -18 to 12; p = 0.77). Bacteremic clearance occurred in 71% (12/17) of cefepime-treated patients and 40% (6/15) of ceftazidime-treated patients (p = 0.3). Both drugs were well tolerated.. Cefepime appears to be as effective as ceftazidime in the initial treatment of febrile episodes in adult cancer patients with chemotherapy-associated neutropenia of modest duration.

Cefepime versus imipenem-cilastatin as empirical monotherapy in 400 febrile patients with short duration neutropenia. CEMIC (Study Group of Infectious Diseases in Cancer).
This open, comparative, randomized, multicentre equivalence study compared cefepime 2 g bd and imipenem-cilastatin 1 g tds (50 mg/kg/day) as empirical monotherapy for febrile episodes in a homogeneous cohort of cancer patients with short duration neutropenia following chemotherapy for solid tumour, lymphoma or myeloma. The study was conducted in 17 French anti-cancer centres in 1995 and 1996. Response to monotherapy was assessed 7 days after treatment and was based on resolution of fever and signs and symptoms, eradication of pathogens, absence of new infection, relapse, and death of infectious origin, without addition of other antibiotics. Patients were treated for a minimum of 4 days. Of the 400 episodes randomized, 344 (86%) were evaluable for efficacy. Patient characteristics were comparable between treatment groups. Success of monotherapy was observed in 79% of episodes with cefepime and 72% with imipenem-cilastatin (equivalence, P <0.0001). The response rate for microbiologically documented infections was 66% with cefepime and 61% with imipenem-cilastatin (bacteraemic episodes: 63% for cefepime; 44% for imipenem-cilastatin). A second antibiotic (usually a glycopeptide) was added in 20% and 21% of the cases, respectively. Overall, the response to therapy, with or without an additional antibiotic, was 95% (cefepime) and 90% (imipenem-cilastatin). Survival was similar in both groups (95% and 98%, respectively). Cefepime treatment was better tolerated, with 9% of the patients experiencing related intercurrent events compared with 19% in the imipenem-cilastatin group (P = 0.003). Nausea/vomiting was significantly more frequent in the imipenem-cilastatin group (15%) than in the cefepime group (5%; P = 0.001). Cefepime monotherapy was as effective as, and better tolerated than, imipenem-cilastatin in the empirical treatment of fever during short duration neutropenia.

Open randomized study of cefepime versus piperacillin-gentamicin for treatment of febrile neutropenic cancer patients.
An open-label randomized trial comparing the efficacy and safety of cefepime versus piperacillin plus gentamicin (P+G) given intravenously for the treatment of febrile episodes in neutropenic patients with underlying malignancy was conducted at two oncology centers. Over a 30-month period 111 patients were enrolled and 99 patients were found to be suitable for evaluation. At the 72-h time of evaluation, cefepime monotherapy and P+G combination therapy produced comparable clinical response rates (78% for both). P+G and cefepime produced comparable response rates in microbiologically documented (78 versus 71%), clinically documented (100 versus 100%), and possible (75 versus 79%) infections. The P+G and cefepime treatments achieved comparable microbiological eradication of gram-negative (100 versus 71%) (P = 0.09) and gram-positive (44 versus 70%) (P = 0.37) organisms. There were no statistically significant differences in the rates of superinfection between the groups; however, more superinfections of fungal origin were noted in the P+G group. Cefepime was demonstrated to be an effective and safe treatment for febrile episodes in neutropenic patients with malignancies, and its lack of nephrotoxicity compared to P+G was noteworthy. Cefepime appears to be a candidate for monotherapy in febrile neutropenic cancer patients.

Clinical experience with single agent and combination regimens in the management of infection in the febrile neutropenic patient.
Choice of antibiotic therapy for the management of infection in the neutropenic patient continues to challenge the clinician. The shift toward gram-positive organisms and the continuing need to provide gram-negative coverage demands the use of an agent or agents that provide coverage for the spectrum of potential infecting organisms. Cefepime is an extended-spectrum fourth-generation cephalosporin that has good activity against gram-positive and gram-negative organisms; in addition, it resists degradation by Bush group 1 beta-lactamases. These properties make this agent a promising candidate for empiric therapy with febrile neutropenic patients. Data presented in this article are from febrile neutropenic cancer patients enrolled into two randomized, prospective, nonblinded comparative U.S. clinical trials. Patients were randomized to receive cefepime (2 g thrice daily) or a comparator regimen of either ceftazidime (2 g thrice daily) or piperacillin + gentamicin (3 g every 4 hours + 1.5 mg/kg every 8 hours). When indicated, vancomycin was added to the regimen. A total of 109 febrile episodes were treated with cefepime and 107 episodes were treated with the comparator regimens. Neutropenia (< or = 500 PMNs/mm3) persisted for > or = 10 days in >40% of episodes and severe neutropenia (< or = 100 PMNs/mm3) in >25%. More than 40% of the total number of episodes were documented bacterial infections. These characteristics did not differ among treatment groups. Duration of therapy was similar in both groups (median: cefepime, 9 days; comparators, 11 days). In >40% of episodes, patients received study therapy without addition of other antibacterials (cefepime, 46%; comparators, 41%). Vancomycin was added in almost half of all the episodes (cefepime, 45%; comparators, 53%). Patients became afebrile by the fourth day of study therapy in approximately 60% of episodes (cefepime, 58%; comparators, 60%). In approximately 75% of the episodes, patients had a satisfactory response at the end of therapy (cefepime, 74%; comparators, 76%); and following approximately 90% of episodes, patients survived for >30 days (cefepime, 90%; comparators, 92%). Eradication rates were similar for all pathogens for cefepime and comparator agents. There were similar numbers of superinfecting organisms in each treatment arm; most involved gram-positive organisms. These multiple measures of efficacy suggest that initial empiric cefepime monotherapy is comparable to the pooled experience with st Topics: Anti-Bacterial Agents; Cefepime; Ceftazidime; Cephalosporins; Drug Therapy, Combination; Female; Fever; Gentamicins; Humans; Male; Middle Aged; Neoplasms; Neutropenia; Penicillins; Piperacillin; Prospective Studies; Superinfection; Vancomycin | 1996 |
Cefepime monotherapy for the empirical treatment of fever in granulocytopenic cancer patients.
In a pilot study, we evaluated the efficacy and the safety of cefepime, a new cephalosporin with extended-spectrum activity against both Gram-positive and Gram-negative bacteria, as empirical monotherapy for 108 febrile episodes in 84 granulocytopenic cancer patients. Cefepime (2 g tds) was given for a minimum of 7 days or until resolution of infection. Of the 108 episodes, 91 were evaluable. Microbiologically documented infections occurred in 25 patients (27%) (18 Gram-positive, 7 Gram-negative), of whom 18 had bacteraemia. Infection was clinically documented in 47 patients (52%) and fever was unexplained in 19 (21%). Overall, 71% (65/91) of the infections resolved. Response rates were 86% (6/7) for Gram-negative infections, 44% (8/18) for Gram-positive infections (57% for cefepime-susceptible Gram-positive bacteria), 77% (36/47) for clinically documented infections and 79% (15/19) for unexplained fevers. Of the 26 patients (29%) whose primary infections did not improve with cefepime monotherapy, 23 responded after the addition of other antibiotics. Sixteen patients (18%) developed secondary infections of which 13 were microbiologically documented; Gram-positive bacteria were isolated from seven patients, Gram-negative bacteria from two, fungi from three and a virus from one. Adverse effects were mild and did not require premature discontinuation of therapy except for one patient who developed an immediate allergic reaction after the first dose of cefepime from which he recovered fully. The survival rate after resolution of granulocytopenia was 96%; three patients died of primary bacterial infection and one from secondary disseminated candidiasis. In this pilot study, cefepime monotherapy appeared safe and effective as empirical therapy for fever in cancer patients with granulocytopenia. Whether cefepime is superior to other advanced-generation cephalosporins for the treatment of Gram-positive infections will require evaluation in a larger comparative study.

A case-control study of Clostridioides difficile symptomatic infections in a pediatric cancer hospital.
The aim of this study was to analyze and identify documented infections and possible risk factors for Clostridioides difficile infections in children with cancer.. This is a retrospective case-control study, carried out in a pediatric cancer hospital, covering the years 2016-2019. Matching was performed by age and underlying disease, and for each case, the number of controls varied from 1 to 3. Logistic regression models were used to assess risk factors.. We analyzed 63 cases of documented infection by C. difficile and 125 controls. Diarrhea was present in all cases, accompanied by fever higher than 38°C in 52.4% of the patients. Mortality was similar among cases (n=4; 6.3%) and controls (n=6; 4.8%; p=0.7). In all, 71% of patients in the case group and 53% in the control group received broad-spectrum antibiotics prior to the infection. For previous use of vancomycin, the Odds Ratio for C. difficile infection was 5.4 (95% confidence interval [95%CI] 2.3-12.5); for meropenem, 4.41 (95%CI 2.1-9.2); and for cefepime, 2.6 (95%CI 1.3-5.1). For the antineoplastic agents, the Odds Ratio for carboplatin was 2.7 (95%CI 1.2-6.2), melphalan 9.04 (95%CI 1.9-42.3), busulfan 16.7 (95%CI 2.1-134.9), and asparaginase 8.97 (95%CI 1.9-42.9).. C. difficile symptomatic infection in children with cancer was associated with previous hospitalization and the use of common antibiotics in cancer patients, such as vancomycin, meropenem, and cefepime, in the last 3 months. Chemotherapy drugs, such as carboplatin, melphalan, busulfan, and asparaginase, were also risk factors.

Cefepime Versus Cefepime Plus Amikacin as an Initial Antibiotic Choice for Pediatric Cancer Patients With Febrile Neutropenia in an Era of Increasing Cefepime Resistance.
We investigated the treatment outcomes before and after the addition of amikacin to cefepime monotherapy as an initial empirical antibiotic treatment in pediatric cancer patients with febrile neutropenia.. This was a retrospective historical cohort study. The subjects were pediatric cancer patients who visited the emergency room at the Samsung Medical Center, Seoul, Korea, due to chemotherapy-induced febrile neutropenia, between January 2011 and December 2016. Since September 2014, the empirical antimicrobial treatment regimen for febrile neutropenia was changed from high-dose cefepime monotherapy to combination therapy of adding a single dose of amikacin.. Two hundred twenty-five bacteremia episodes in 164 patients were reported during the study period. Bacteremia caused by cefepime-resistant Gram-negative bacteria was observed in 16% of patients before September 2014 and in 21% of the patients after September 2014 (P = 0.331). Use of appropriate empirical antibiotic treatments increased from 62% to 83% following addition of amikacin to cefepime treatment (P = 0.003). The duration of fever was shorter in the cefepime plus amikacin group than in the cefepime group (22 vs. 34 hours, P = 0.014); however, rates of septic shock and pediatric intensive care unit hospitalizations were not significantly different between the 2 groups (septic shock, both 7%, P = 0.436; pediatric intensive care unit 3% vs. 1%, P = 0.647).. We observed no additional benefit of amikacin addition to high-dose cefepime monotherapy. Therefore, adding amikacin to cefepime monotherapy in conditions where cefepime-resistant Gram-negative bacteremia amounts to 20% or less may not be justified.

Reducing acute kidney injury in pediatric oncology patients: An improvement project targeting nephrotoxic medications.
Nephrotoxic medication exposure and associated acute kidney injury (AKI) occur commonly in hospitalized children. At Cincinnati Children's Hospital Medical Center, there is an initiative to increase awareness of nephrotoxic medication exposure and decrease rates of associated AKI. The oncology service utilized these data in a quality improvement project to drive reductions in AKI rates.. Three interventions were implemented targeted at decreasing the incidence of nephrotoxic exposure, as well as protecting against the conversion of exposures to AKI episodes. Cefepime replaced piperacillin-tazobactam for febrile neutropenia, vancomycin stewardship limited empiric courses to 72 hours, and nephroprotection for intravenous contrast administration was standardized for defined high-risk patients.. The study cohort comprised 42 520 noncritically ill patient days admitted to the oncology service at Cincinnati Children's Hospital Medical Center. A total of 273 unique patients were exposed to combination nephrotoxic medications, leading to 111 AKI episodes. The rate of nephrotoxic medication exposure within the oncology service decreased by 49% from 16.08 to 8.17 per 1000 patient days. Episodes of AKI associated with nephrotoxic medication exposure decreased by 45% from 3.48 to 1.92 per 1000 patient days.. Interventions to decrease AKI took a three-pronged approach. Collectively, this approach was proven successful with significant reductions in both rates of nephrotoxic medication exposure and associated AKI among hospitalized oncology patients.

Cefepime Therapy for Monomicrobial Enterobacter cloacae Bacteremia: Unfavorable Outcomes in Patients Infected by Cefepime-Susceptible Dose-Dependent Isolates.
A new category of cefepime susceptibility, susceptible dose dependent (SDD), for Enterobacteriaceae, has been suggested to maximize its clinical use. However, clinical evidence supporting such a therapeutic strategy is limited. A retrospective study of 305 adults with monomicrobial Enterobacter cloacae bacteremia at a medical center from 2008 to 2012 was conducted. The patients definitively treated with in vitro active cefepime (cases) were compared with those treated with a carbapenem (controls) to assess therapeutic effectiveness. The 30-day crude mortality rate is the primary endpoint, and clinical prognostic factors are assessed. Of 144 patients receiving definitive cefepime or carbapenem therapy, there were no significant differences in terms of age, sex, comorbidity, source of bacteremia, disease severity, or 30-day mortality (26.4% versus 22.2%; P = 0.7) among those treated with cefepime (n = 72) or a carbapenem (n = 72). In the multivariate analysis, the presence of critical illness, rapidly fatal underlying disease, extended-spectrum beta-lactamase (ESBL) producers, and cefepime-SDD (cefepime MIC, 4 to 8 μg/ml) isolates was independently associated with 30-day mortality. Moreover, those infected by cefepime-SDD isolates with definitive cefepime therapy had a higher mortality rate than those treated with a carbapenem (5/7 [71.4%], versus 2/11 [18.2%]; P = 0.045). Cefepime is one of the therapeutic alternatives for cefepime-susceptible E. cloacae bacteremia but is inefficient for cases of cefepime-SDD E. cloacae bacteremia compared with carbapenem therapy.

Impact of antibiotic use during hospitalization on the development of gastrointestinal colonization with Escherichia coli with reduced fluoroquinolone susceptibility.
Infections due to fluoroquinolone-resistant Escherichia coli (FQREC) are associated with significant morbidity and mortality. Fluoroquinolone resistance likely arises at the level of gastrointestinal colonization. The objective of this study was to identify risk factors for the development of FQREC gastrointestinal tract colonization in hospitalized patients, including the impact of antibiotics prescribed during hospitalization.. A prospective cohort study was conducted from 2002 to 2004 within a university health system.. Hospitalized patients initially colonized with fluoroquinolone-susceptible E. coli were followed up with serial fecal sampling for new FQREC colonization or until hospital discharge or death. A Cox proportional hazards regression model was developed to identify risk factors for new FQREC colonization, with antibiotic exposure modeled as time-varying covariates.. Of 395 subjects, 73 (18.5%) became newly colonized with FQREC. Length of stay before sampling (hazard ratio [HR], 1.02 [95% confidence interval (CI), 1.1-1.03]; P = .003) and malignancy (HR, 0.37 [95% CI, 0.21-0.67]; P = .001) were significantly associated with the development of FQREC colonization. In addition, receipt of a first-generation cephalosporin (HR, 1.19 [95% CI, 1.10-1.29]; P < .001) or cefepime (HR, 1.05 [95% CI, 1.00-1.10]; P = .048) during hospitalization increased the risk of new FQREC colonization.. The acquisition of FQREC in the hospital setting is complex, and antimicrobial stewardship programs should take into account patterns of antibiotic use in implementing strategies to reduce the development of new FQREC colonization. Future studies are needed to identify risk factors for infection in hospitalized patients newly colonized with FQREC.

The safety of cefepime and ceftazidime in pediatric oncology patients.
Concern has been raised about possible increased mortality associated with the use of cefepime. There are limited data available on the pragmatic use of beta-lactam antibiotics, especially in children.. This retrospective study included 532 pediatric oncology patients. The outcomes of patients treated with cefepime for suspected serious bacterial infections were compared to those of patients treated with ceftazidime. Primary outcomes included 30- and 90-day all-cause mortality.. The demographic and clinical characteristics of 337 patients treated with ceftazidime were similar to those of 195 patients receiving cefepime. Thirty-day and 90-day all cause mortality rates were comparable (30-day OR for cefepime: 3.48, 95% CI 0.31-38.84, P = 0.3; 90-day OR: 0.99, 95% CI 0.29-3.42, P = 1.0). There were also no differences in infection-related mortality rates, secondary infections, or adverse drug events. Deaths occurring within 30 days of hospitalization were judged to be attributable to infection, but not the result of treatment failure or adverse drug events. Deaths occurring between 30 and 90 days were associated with progressive or new malignancy. Secondary infection was significantly associated with mortality.. The use of cefepime in pediatric oncology patients is not associated with increased mortality when compared to ceftazidime, however the small number of deaths in this study limits the strength of this conclusion. Previous associations between antimicrobial therapy and increased all-cause mortality may have been confounded by patients' demographic characteristics and co-morbid conditions. All-cause mortality may be an insensitive outcome for studies examining the efficacy and safety of these agents.

[Cefepime versus piperacillin/tazobactam with or without amikacin in the treatment of febrile hematological and oncological neutropenic patients in an internal medicine ward].
The efficacy of conventional doses of piperacillin/ tazobactam (PTZ) plus amikacin (AMK) were compared retrospectively to low doses of cefepime (CEF) plus amikacin in high risk febrile neutropenic patients with an underlying hematologic malignancy, and CEF versus PTZ (without AMK) in low risk individuals with febrile neutropenia and underlying solid tumor malignancies.. Fifty-six high risk hematologic malignancy patients received a combination of PTZ 4.5 grams administered every 8 hours plus AMK 15 mg/kg/day, while 46 received CEF 1 gram administered every 12 hours plus AMK 15 mg/kg/day. In addition, 19 febrile neutropenic individuals with underlying solid malignancies received PTZ 4.5 grams every 8 hours and 25 received CEF 1 gram every 12 hours. All patients were treated in an isolation unit section of a general internal medicine ward.. There was no significant difference between the groups in terms of age, depth of neutropenia, microbiologic result, morbidity, length of hospital stay or mortality.. PTZ and CEF in combination with AMK were equally efficacious in neutropenic patients with hematologic malignancies. In addition, monotherapy with CEF or PTZ proved to be equally efficacious in neutropenic patients with solid tumors. Low dose CEF is safe and allows a reduction of cost and less antibiotic exposure.

Influence of plasma exchange on the disposition of the fourth generation cephalosporin cefepime.
Cefepime, a fourth generation cephalosporin, is widely used in hematology and oncology patients. These patients may require plasma exchange (PE) for indications such as chemotherapy- or cancer-induced thromobotic thrombocytopenic purpura to name a few. To date, no pharmacokinetic evaluation has been conducted assessing cefepime's disposition during PE. A 2 g IV cefepime single dose was given to patients undergoing therapeutic PE. Two hours from cefepime dose administration, plasma concentration was measured. PE was then instituted and cefepime plasmapheresate concentration was measured at the completion of the PE session. Cefepime levels were measured using HPLC. The percentage removed by PE was calculated as: amount removed/2 g dose. Ten adult patients were analyzed: median age (range): 52 years (33-67) and median weight (range); 82.85 kg (47-120). PE indications were: myasthenia gravis (n = 3), transverse myelitis (n = 2), multiple sclerosis (n = 1), chronic inflammatory demyelinating polyneuropathy (n = 1), idiopathic thrombocytopenic purpura (n = 1), thrombotic thrombocytopenic purpura (n = 1), and humoral rejection post cadaveric renal allograft (n = 1). All patients except one had a creatinine clearance >60 mL/min. One patient was excluded from the pharmacokinetic analysis owing to loss of venous access during PE. For the remaining nine patients, total plasma volume removed was 3.5 L (range: 2.5-3.5) and duration of PE was 120 min (range: 94-209). The cefepime removed by PE was 3.7% (range: 2.1-6.7). A strong correlation was found between cefepime plasma concentration prior to PE and the amount of drug removed (r = 0.96, r(2) = 0.92; p<0.05). The above results suggest that, under the studied conditions, cefepime removal by PE is clinically insignificant (approximately 4% of total 2 g dose).

Trough serum concentrations of beta-lactam antibiotics in cancer patients: inappropriateness of conventional schedules to pharmacokinetic/pharmacodynamic properties of beta-lactams.
Serum concentrations of beta-lactams that continuously exceed the minimum inhibitory concentration may improve therapeutic outcomes for immunosuppressed patients. The trough serum levels of ceftazidime (CAZ), cefepime (FEP) or imipenem (IMP) were prospectively determined on days 1 and 3 of treatment in cancer patients. Seventy-eight episodes of suspected infection were analysed. Trough serum levels were higher than 4 mg/L in 62%, 24% and 0% of cases in the CAZ, FEP and IMP groups, respectively, and were higher than 20 mg/L in 24% of cases in the CAZ group compared with 0% both in the FEP and IMP groups. For suspected infectious episodes in cancer patients, the traditional intermittent regimen of beta-lactams does not appear to be appropriate for the pharmacokinetic/pharmacodynamic properties of these antibiotics.

[3-Year experience of use of cefepime (Maxipime) for the treatment of hospital infections in a specialized surgical hospital].
Microbiological and clinical monitoring for 3 years (from 2001 to 2003) confirmed high clinical and microbiological efficacy of cefepime (Maxipime, Bristol-Myers-Squibb) in the treatment of infectious complications in patients with solid tumors in an oncologic hospital. It should be noted, however, that high efficacy of cefepime and wide ranges of the indications to its use do not allow to consider it as an agent for the treatment of all possible complications in such patients. The drug is not active against enterococci, not always clinically sufficiently effective in the treatment of Pseudomonas aeruginosa infections, it is impossible to use cefepime in monotherapy of suspected anaerobic infections. Therefore, widespread uncontrolled use of cefepime should be prohibited. It should be prescribed strictly by the indications with the account of the pathogen susceptibility, the infection severity and the recommended doses and regimens. The use of cefepime is undoubtedly valid when other antimicrobials fail or when empirical antimicrobial therapy of severe cases is required, including those under intensive care.

[Cefepime-amikacin combination in febrile neutropenic children with malignant hemopathy or tumor].
Our aim was to evaluate retrospectively the efficacy of a therapeutic strategy with a first line combination based on cefepime-amikacin in febrile neutropenic children treated with chemotherapy.. Sixty-five neutropenic febrile episodes in 43 children treated by the association cefepime-amikacin, were evaluated according to the clinical status, the depth and duration of neutropenia, the underlying disease and the initial treatment.. Thirty-nine (60%) episodes were successfully treated by the association cefepime-amikacin. Among the 26 persisting febrile episodes, adjunction of vancomycin and amphotericin B was effective in 11 (76% of total rate success) and 5 (84% of total rate success) cases respectively. The efficacy of the first line antibiotherapy was not different as regards to the duration and the depth of neutropenia. Otherwise, febrile episodes after chemotherapy against solid tumours were rapidly controlled by the first and second line of the anti-microbial strategy. Children treated for haematological malignancies presented a lower response rate (P = 0.03).. In febrile and neutropenic children treated with chemotherapy, the association cefepime-amikacin appeared to be a safe empirical treatment. In a neutropenic child, the immunodeficiency and possibly the clinical status should be the major factors of the infectious prognosis more than the duration of aplasia.

Prospective study of bacteraemia in cancer patients. Results of a French multicentre study.
We performed a prospective assessment of the current epidemiology of bacteraemia in cancer patients hospitalized in 70 different adult and paediatric haematology and oncology departments. Over a 1-month period, microbiologists from 54 hospitals collected clinical data relating to patients with at least one positive blood culture. In addition, all strains isolated were assessed for their in vitro susceptibility to three broad-spectrum cephalosporins suitable for empirical treatment in cancer patients: cefpirome, cefepime and ceftazidime. A total of 494 different strains were isolated from 1,038 blood cultures taken from 403 different patients. Seventeen strains were isolated from 13 patients with various nonmalignant diseases, and these cases were excluded from analysis. Overall, 330 (69.2%) of the strains were isolated in patients with haematological malignancy and 147 (30.8%), in patients with solid tumours. There was no difference in the distribution of the species involved in bacteraemia between patients with haematological malignancy and patients with solid tumours: coagulase-negative staphylococci were the leading pathogens (50.6% and 44.9%, respectively), followed by E. coli (11.2% and 12.2% respectively), S. aureus (6.3% vs 7.5%), streptococci (4.8% vs 5.4%) and P. aeruginosa (5.2% vs 4.8%). All other species accounted for less than 5% in both groups. There was no difference in the strain distribution with age (> or = 15 years vs < 15 years) or type of underlying disease. S. aureus and Enterobacteriaceae bacteraemia were more frequent in patients with end-stage disease, while oral streptococci, Enterobacteriaceae and P. aeruginosa infections were more frequent in patients who were severely neutropenic. Digestive tract decontamination was associated with increased frequency of oral streptococci and decreased frequency of Enterobacteriaceae infections. All three cephalosporins demonstrated similar activity against E. coli, while cefpirome and cefepime appeared to be more effective against other Enterobacteriaceae. Ceftazidime had better activity against P. aeruginosa. Cefpirome was the most effective against Gram-positive cocci, especially oral streptococci and methicillin-susceptible staphylococci.

In-vitro activity of cefpirome (HR-810), WIN-49375, BMY-28142 and other antibiotics against nosocomially important isolates from cancer patients.
The activity of three new antimicrobial agents [cefpirome (HR 810), BMY 28142, WIN 49375], and imipenem was compared to that of four currently available agents, ceftazidime, aztreonam, timentin and piperacillin, against 253 bacterial isolates from cancer patients. The activity of all four agents not yet in clinical use at our institution was significantly greater than that of the four antibiotics already in use.
