This study was performed in order to: (i) determine the incidence of symptomatic urinary tract infection (UTI) in patients with spinal cord injury after urodynamic testing; (ii) evaluate the role of antibiotic prophylaxis for such a procedure; and (iii) investigate whether pre-existing bacteriuria predisposes to the development of symptomatic UTI after urodynamic testing. Forty patients were prospectively randomized in a double-blind fashion to receive a 3-day oral course of either ciprofloxacin (18 patients) or placebo (22 patients), beginning 2 days prior to the urodynamic procedure. None of 18 (0%) patients who received ciprofloxacin developed symptomatic UTI within 5 days after the procedure compared with three of 22 (14%) subjects randomized to the placebo group; the protective efficacy of antibiotic prophylaxis, however, did not attain statistical significance (P = 0.24). None of the three bacterial isolates that were responsible for symptomatic infection were grown in corresponding urine cultures prior to the procedure. These findings may serve as a pilot for a larger study. Post-cesarean-section endometritis therapy usually combines an intravenous administered antibiotic followed, once fever has remitted, by an oral or intramuscular course of 7-10 days of the same antibiotic. From November 1993 to May 1994 and trying to reduce the length of the treatment we conducted a randomized, comparative study between the conventional post-C-section endometritis treatment used at the Hospital Central Militar (long course) and a short parenteral treatment with the same antibiotics. Thirty one patients were randomized in the short course group and 32 in the long course group. Only in the long course group there was a patient with persistence of infection after ten days of antibiotic treatment (p > 0.05). The short course regimen brought additional advantages as reduction in treatment days as well as discomfort for the intramuscular administration of antibiotics. This observation suggests that a short course of antibiotics based on the patient's clinical response is a safe and less expensive alternative in the treatment of post-C-section endometritis. In an attempt to determine the optimal duration of therapy of spontaneous bacterial peritonitis, 100 patients with neutrocytic ascites and suspected spontaneous bacterial peritonitis were randomized to short-course vs. long-course treatment groups. Empiric therapy was initiated before the results of ascitic fluid culture were available. Of the 90 patients who met strict criteria for spontaneous bacterial peritonitis or culture-negative neutrocytic ascites, 43 were randomized to a group receiving 5 days and 47 to a group receiving 10 days of single-agent cefotaxime, 2 g IV every 8 hours. Infection-related mortality (0% vs. 4.3%), hospitalization mortality (32.6% vs. 42.5%), bacteriologic cure (93.1% vs. 91.2%), and recurrence of ascitic fluid infection (11.6% vs. 12.8%) were not significantly different between the 5- and 10-day treatment groups, respectively. Recurrence rates were comparable to the values reported in the literature. The cost of antibiotic and antibiotic administration were significantly lower in the short-course group. Short-course treatment of spontaneous bacterial peritonitis is as efficacious as long-course therapy and significantly less expensive. Fosfomycin trometamol (FT), an antibiotic active against the common urinary pathogens, may be demonstrated in adequate urine concentrations up to 36-48 h after a single oral dose of 1-2 g. This pharmacokinetic peculiarity seems to indicate that this antibiotic may be used in single doses in the therapy of lower urinary tract infections (UTIs) in infants and children. The efficacy and safety of FT in single oral doses was compared with those of netilmicin (NM), an aminoglycoside antibiotic with a demonstrated efficacy in bolus doses against UTIs, shown in a multicentric study. One hundred and thirty-five children with lower UTI, diagnosed on the basis of fever (less than 38 degrees C), erythrocyte sedimentation rate (less than 25 mm/l h) and C-reactive protein (less than 20 micrograms/ml), were included in the study: 71 received 2 g of FT, 64 5 mg/kg of NM. Cure, defined as persistence of sterile urine up to 30 days after therapy, was reached in 80.2% of children in the FT group and in 81.2% of children in the NM group. Persistence of infection was demonstrated in 7 and in 3 children, respectively. Recurrence of infection was noticed in 7 patients in the FT group and in 9 in the NM group. No differences between FT- and NM-treated children are demonstrable even if the patient population is analyzed according to the higher risk of UTI because of the presence of an anatomical and/or functional abnormality of the urinary tract or due to a previous tendency to recurrent UTIs. FT is as effective as NM in the treatment of lower UTIs in infants and children. A prospective trial was undertaken on 85 adult patients with open fractures of the distal phalanges of less than 6 hours duration, treated by conventional surgery. They either received no antibiotic therapy, or cephradine in short or long courses. The infection rate was 30% in the group without antibiotics and less than 3% in the treated groups. Three different antibiotics regimes were compared, with no difference in the infection rate: therefore the simplest and surest method, a single pre-operative dose and a single post-operative dose, is recommended. The optimal duration of antibiotic therapy in older patients with uncomplicated urinary tract infection (UTI) is still a matter of debate. The aim of this randomized controlled double-blind noninferiority trial was to compare the efficacy and safety of 3-day and 7-day courses of oral ciprofloxacin for uncomplicated symptomatic UTI in older women.
                A total of 183 women at least 65 years of age with acute uncomplicated UTI were recruited from ambulatory clinics and hospital acute care units. Patients with pyelonephritis, contraindications to fluoroquinolones, recent use of antibiotics, urinary tract abnormalities and diabetes mellitus were excluded. Women were randomly assigned to receive either ciprofloxacin 250 mg twice daily orally for 3 days followed by placebo for 4 days (the 3-day group, 93 patients) or ciprofloxacin 250 mg twice daily orally for 7 days (the 7-day group, 90 patients). Bacterial eradication, clinical improvement and occurrence of adverse events were determined 2 days after completion of treatment, and occurrence of reinfection or relapse were determined 6 weeks after completion of treatment. Bacterial eradication and relapse were determined by urine culture. Double-blind procedures were maintained throughout data collection.
                The proportion of patients with bacterial eradication at 2 days after treatment was 98% (91/93) in the 3-day group and 93% (83/89) in the 7-day group (p = 0.16). The frequency of adverse events, including drowsiness, headache, nausea or vomiting, and loss of appetite, was significantly lower in the 3-day group.
                These results suggest that a 3-day course of antibiotic therapy is not inferior to a 7-day course for treatment of uncomplicated symptomatic UTI in older women, and that the shorter course is better tolerated. In recent years there have been changes in the recommended antibiotic treatment for urinary tract infections (UTIs). In particular, the use of amoxycillin or co-trimoxazole is now discouraged, with amoxycillin-potassium clavulanate, cephalexin and trimethoprim becoming first-line agents for uncomplicated lower UTIs.
                To examine whether academic detailing, performed by a pharmacist, could modify prescribing practices for antibiotics used in the treatment of UTI in the community setting.
                The intervention was conducted in Southern Tasmania, using the remainder of the State as a control area. The target group of general practitioners was sent educational material designed to assist in the appropriate prescribing of antibiotics in the treatment of UTI. A pharmacist then visited each general practitioner and discussed the rational use of antibiotics for UTIs directly with him/her. Outcomes were measured using evaluation feedback from the general practitioners and pharmacoepidemiological data, which were not linked to diagnosis. The key variable examined was the total defined daily doses (DDDs) dispensed for the recommended first-line agents (amoxycillin-potassium clavulanate, cephalexin and trimethoprim) compared with amoxycillin (3 g single-dose form) and co-trimoxazole.
                The educational programme was very well received by the general practitioners. Changes in the prescribing of antibiotics commonly used for UTIs were evident in both study regions over the course of the study, but the improvements were significantly greater in the intervention area.
                Educational programmes utilizing academic detailing by pharmacists can modify prescribing practices within the community setting. The purpose of this paper was to compare the efficacy of a single dose of 3 g of fosfomycin to that of a 7-day regimen of amoxicillin-clavulanate in the treatment of asymptomatic bacteriuria during pregnancy. A randomised, prospective, interventional, analytical, longitudinal study was undertaken, in which the efficacy of two antibiotic regimens (one short and the other long) in the treatment of pregnant women with asymptomatic bacteriuria is compared. One hundred and nine patients were randomly assigned to two groups: 56 were treated with amoxicillin-clavulanate and 53 with fosfomycin. The two groups were similar in terms of co-morbidity, treatments received during pregnancy, obstetric, gynaecological and surgical history and laboratory data. The efficacy of the two regimens was similar and the eradication rate was over 80% in both groups (P = 0.720) (relative risk [RR] 1.195, 95% confidence interval [CI]: 0.451-3.165). The number of reinfections was greater in the amoxicillin-clavulanate group (P = 0.045). The secondary effects were lower in the fosfomycin group (P = 0.008). There were no significant differences in the number of persistences (P = 0.39), development of symptomatic urinary infections (P = 0.319) or recurrences (P = 0.96). Treatment with a single dose of fosfomycin is as effective as the standard course of treatment with amoxicillin-clavulanate and may be preferable due to its simpler administration and the smaller number of reinfections. Recurrent Clostridium difficile disease (CDD) is a difficult clinical problem because antibiotic therapy often does not prevent further recurrences. In a previous study, the biotherapeutic agent Saccharomyces boulardii was used in combination with standard antibiotics and was found to be effective in reducing subsequent recurrences of CDD. In an effort to further refine a standard regimen, we tested patients receiving a regimen of a standard antibiotic for 10 days and then added either S. boulardii (1 g/day for 28 days) or placebo. A significant decrease in recurrences was observed only in patients treated with high-dose vancomycin (2 g/day) and S. boulardii (16.7%), compared with those who received high-dose vancomycin and placebo (50%; P=.05). No serious adverse reactions were observed in these patients. Comparison of data from this trial with data from previous studies indicates that recurrent CDD may respond to a short course of high-dose vancomycin or to longer courses of low-dose vancomycin when either is combined with S. boulardii. To evaluate the role of primary vesicoureteral reflux (VUR) in increasing the frequency and severity of urinary tract infections (UTIs) and renal parenchymal damage among patients with acute pyelonephritis and to determine whether urinary antibiotic prophylaxis reduces the frequency and/or severity of UTIs and/or prevents renal parenchymal damage among patients with mild/moderate VUR.
                Patients 3 months to 18 years of age with acute pyelonephritis, with or without VUR, were assigned randomly to receive urinary antibiotic prophylaxis or not. Patients were monitored every 3 months for 1 year. Dimercaptosuccinic acid renal scans were repeated at 6 months or if there was a recurrence of febrile UTI. Urinalysis and urine culture were performed at each clinic visit. Renal ultrasound scans and voiding cystourethrograms were repeated at the end of 1 year of follow-up monitoring.
                Of the 236 patients enrolled in the study, 218 completed the 1-year follow-up monitoring. Groups were similar with respect to age, gender, and reflux grade distribution for those with VUR. No statistically significant differences were found among the groups with respect to rate of recurrent UTI, type of recurrence, rate of subsequent pyelonephritis, and development of renal parenchymal scars.
                After 1 year of follow-up monitoring, mild/moderate VUR does not increase the incidence of UTI, pyelonephritis, or renal scarring after acute pyelonephritis. Moreover, a role for urinary antibiotic prophylaxis in preventing the recurrence of infection and the development of renal scars is not supported by this study. We evaluated the optimal means of prevention and treatment of urinary tract infections in 46 patients with an intermittently catheterized neurogenic bladder. Suppression with nightly 160 mg. trimethoprim and 800 mg. sulfamethoxazole compared to placebo showed no difference in the rate of symptomatic or total urinary tract infections. Symptomatic urinary tract infections occurred at the same rate whether routine asymptomatic infections were treated or not. Three-day antibiotic treatment of urinary tract infections showed no decrease in the frequency of symptomatic or total urinary tract infections compared to 10-day therapy. The frequency of post-treatment urinary tract infection persistence, relapse and cure was identical in both groups. Suppressive antibiotics, treatment of asymptomatic urinary tract infections and full course antibiotic therapy offered no advantage over placebo, treatment of symptomatic urinary tract infection only and short course therapy in the management of urinary tract infection in patients with an intermittently catheterized neurogenic bladder. To evaluate the safety and efficacy of an abbreviated course of antibiotic therapy in postpartum endomyometritis, 109 patients with endomyometritis were randomized to three study groups. All were treated with clindamycin and tobramycin until afebrility and clinical signs of disease were absent. Patients in group I received antibiotics for greater than or equal to 24 hours, group II received therapy for greater than or equal to 48 hours, and group III received antibiotic therapy for greater than or equal to 48 hours that preceded a 7-day course of oral Augmentin. The groups were similar in size and in demographic and clinical parameters. Two patients from each group required a third antibiotic, and no patient required rehospitalization. Group III required more days of antibiotic therapy than did group I, 2.9 versus 2.1 days (p less than 0.01), and cost $412.00 more per patient. This data strongly suggest that a short course of antibiotic therapy is efficacious and safe and would result in substantial monetary savings.
Although antibiotic treatment is effective for children with UTI, there are insufficient data to answer the question of which type of antibiotic or which duration is most effective to treat symptomatic lower UTI. This review found that 10-day antibiotic treatment is more likely to eliminate bacteria from the urine than single-dose treatments. No differences were observed for persistent bacteriuria, recurrence or re-infection between short and long-course antibiotics where the antibiotic differed between groups. This data adds to an existing Cochrane review comparing short and long-course treatment of the same antibiotic who also reported no evidence of difference between short and long-course antibiotics.
