Prevalence of chronic kidney disease in children of school going age visiting outpatient department of A Tertiary Care Hospital in Karachi, Pakistan.

Objective: To determine the prevalence of chronic kidney disease (CKD) among children of school-going age. Study Design: Cross-sectional study. Setting: Department of Pediatric Medicine, National Institute of Child Health, Karachi, Pakistan. Period: July 2023 to December 2023. Methods: A total of 130 children of both genders, aged between 5-15 years, visiting outpatient department of pediatric medicine were analyzed. Demographic and clinical information were noted. Laboratory investigations like urinalysis and serum creatinine were performed. CKD was diagnosed on the basis of “Kidney Disease Outcomes Quality Initiative (KDOQI)” guidelines. Results: In a total of 130 children, 67 (51.5%) children were male. Overall, the mean age was 8.43±2.45 years. Hypertension was diagnosed in 10 (7.7%) children. Anemia was present in 103 (79.2%) patients. The mean hemoglobin, serum creatinine, and blood urea nitrogen were 9.41±1.98 g/dl, 0.48±0.37 mg/dl, and 34.20±33.18 mg/dl, respectively. CKD was diagnosed in 10 (7.7%) children. Among these 10 children diagnosed with CKD, 7 were having CKD stage-1 whereas CKD stage-2 was noted in 3 children. Presence of hypertension (p=0.006), and albuminuria (p<0.001) were associated with CKD. Conclusion: The prevalence of CKD in school going age children was 7.7%. Presence of hypertension, and albuminuria were linked with CKD.
