Clinico-Microbiological Profile and Clinical Predictor of Urinary Tract Infection in Children: A Single-Center Study From Himalayan Foothills.

backgroundUrinary tract infection (UTI) in children is one of the commonest bacterial infections seen in the pediatric population. Clinical presentation ranges from fever with or without focus and isolation of microbiological agents streamline the treatment. Moreover, local/regional microbial profiles are helpful in antibiotic selection, we conducted a study to assess the prevalence of urine culture positivity in a suspected case of UTI. In addition, antibiotic susceptibility patterns and ultrasonography (USG) finding in culture-positive patients were also studied. METHODS AND MATERIALS: It is a prospective observational study comprising symptomatic children aged one month to 18 years presenting to the outpatient department (OPD), inpatient department (IPD), and the emergency department of Pediatrics with UTI during the period of September 2019 to September 2020. The recorded variables were demographic, clinical presentation, anthropometry, physical examination, blood biochemistry, and outcome. Urine samples were collected and processed as per standard protocols. USG was done for all culture-positive children. Data were presented as frequency, mean (SD) and parametric and non-parametric data were analyzed by Wilcoxon-Mann-Whitney U Test, Chi-Squared Test, or Fisher's Exact Test.  Results: Of the total 354 children, 202 (57.1%) were male and the prevalence of UTI was 64 (18.1%). E. coli (70.3%) was the commonest isolated organism followed by Klebsiella spp (15.6%) and Pseudomonas spp (7%) respectively. The mean (SD) age (months) of presentation of symptoms was significantly lower in culture-positive children as compared to [ 83.49 (58.96) vs 110.10 (58.60); p=0.001] culture-negative children. Fever (96.6%) followed by dysuria (20.1%) were the most common symptoms presented for UTI however dysuria (p=0.003), pus cells (p<0.0001), and RBCs (p=0.002) were significantly present in culture positive children. This study shows increased resistance to third generation of cephalosporins. This study revealed significant differences among various groups (organism growth in positive culture) and the Antibiotic susceptibility test (AST) with a p-value of <0.001.  Conclusion: The prevalence of culture-positive UTI was similar to the reported literature and the presence of fever, dysuria, pus cells, and RBC in urine were commonly observed in the lower age group. Amikacin can be used in suspected UTIs with cephalosporin as empirical antibiotics in the Himalayan Foothills region.
