Abstract The high urinary drug concentrations usually encountered after administering nitrofurantoin in the chemotherapy of urinary tract infections are often measured by the nitromethane—Hyamine method. We show here that, if the urinary tract analgesic, phenazopyridine hydrochloride, and its related metabolite(s) are in the urine, they interfere with this determination of nitrofurantoin. Nevertheless, the nitromethane—Hyamine method may be modified to determine nitrofurantoin quantitatively in urine collected from human subjects who have been treated with the analgesic and nitrofurantoin concomitantly.

INTRODUCTION: The study under view is based under the aim to investigate the prevalence and susceptibility pattern of pathogens, causing urinary tract infections (UTIs), to antibiotics commonly used in routine medication. MATERIALS AND METHODS: Over a period of 10 months 100 isolates were collected for the determination of their susceptibility to chosen antibiotics, from a laboratory (MedPath Laboratories) in urban area of Karachi. All Gramnegative and Gram-positive urinary tract pathogens were re-identified by their morphological and biochemical characteristics and the susceptibility to seven antibiotics was determined. RESULTS: Pathogens were found as, Escherichia coli, Pseudomona spp, Klebsiella species, Enterobacter spp., and Staphylococci spp. In recent study, more than half of the Escherichia coli isolates were resistant to one or more of the all antimicrobial drugs tested. Resistance was most common to amoxicillin/clavulanic acid and ofloxacin, cefixime, followed by gentamicin. Our results indicate that Escherichia coli and Pseudomonas spp. were the most common organisms causing UTI. Other organisms involved were Enterobacter spp., Staphylococcus spp., and Klebsiella spp. Increasing patterns of resistant to gentamicin, and ofloxacin were also observed. CONCLUSIONS: In conclusion, pattern of antibiotic susceptibility to first line antibiotics is changing hence antimicrobial susceptibility testing of all isolates is crucial for the treatment of UTI.

Tract Infections

Background: Urinary tract infections (UTIs) represent the most common cause of bacterial infection in renal allograft recipients. The purpose of this study was to evaluate UTI in renal transplant recipients at earlier post transplant period (first 3 months) and isolation of causative organism. Materials & methods: We studied 31 patients (18 males and 13 females), aged 27 ± 8.8 years. UTIs occurring during the first three months were analyzed. During this period, all episodes of infection, transplant function, graft survival and patient survival were monitored. Results: Twenty two patients had suffered from different types of infection within first 3 months of transplantation, most of the infectious episodes occurred during hospital stay. Most of the infection occurred in urinary tract and most of the episodes of UTI were asymptomatic, presented with bacteriuria. Most of the isolated organisms were Gram negative E.Coli. Out of 51 episodes of bacterial infection, UTIs account for 49 episodes (96%) Patients’ age, sex and acute rejection episodes did not correlate with UTI. Patient who had prolonged urethral catheterization had suffered from significantly more number of UTI in comparison to short period of urethral catheterization (p=0.02).Similar incidence of UTI were observed in ureteric stented and non stented patients but non stented patients had suffered from significant number of urological complication (p<0.02) . Antibiotic sensitivity pattern revealed that, all isolates were sensitive to ciprofloxacin, ceftriaxone and ceftazidime, ranged between, 67 to 100% and highly resistant to ampicillin, cotrimoxazole and cephradine. Conclusion : Short term renal graft function was not found to be affected by UTI occurrence. UTIs are common infectious complications in renal transplant recipients and often relapse and require hospitalization.

One hundred four patients with 124 episodes of urinary tract infection were studied. Serum C-reactive protein (CRP) was determined on diagnosis of each patient. Children with a CRP equal to or greater than 30 µg/ml (CRP-pos) differed significantly from those with values less than 30 µ/ml (CRP-neg) in age, clinical presentation, K type of Escherichia coli causing disease, frequency or radiographic abnormalities, and presence of antibody coating of bacteria in the urinary sediment. E coli K1 strains caused disease significantly more often in CRP-pos than in CRP-neg patients, and children with K1 infections were younger than those with non-K1 infections. The antibody-coated bacteria test was neither sensitive nor specific for localization of infection in pediatric patients. Determination of K1 antibody concentrations in serum and urine of E coli K1-infected children provided data supporting the measurement of CRP as one means of localizing urinary tract infections. Patients with CRP-neg infections were treated as successfully with four days of antimicrobial therapy as with ten days.
