Prevalence and predictors of ocular complications among children with nephrotic syndrome in a resource-limited setting

Abstract

Background Nephrotic syndrome is the most common glomerulopathy among children aged 2–18 years and high dose corticosteroids are the backbone of its management. Potentially blinding ocular complications often result from nephrotic syndrome and/or its treatment. We conducted a study to determine the prevalence and predictors of ocular complications among children with nephrotic syndrome receiving care at Mulago National Referral Hospital. Methods This was a cross-sectional study conducted for three (3) months at pediatric renal unit of Mulago National Referral Hospital (MNRH). Data from a consecutive sample of 100 children was collected using a semi-structured questionnaire, entered into Epi-data 4.4.2 and exported to STATA 14 for analysis at univariate, bivariate and multivariate levels. A robust Poisson regression model was used to identify predictors of ocular complications. Results Out of 100 patients examined, 80(80%) had ocular complications. The median age was 10 (IQR: 7–12) and 52 (52%) were girls. The most frequent complications were hypertrichosis and refractive errors in 71%(95%CI 61.1–79.6) and 56%(95%CI 45.7–65.9) of the patients respectively. Age above 10 years was the predictor for ocular complications with a RR = 1.37 (95%CI:1.14–1.64) P = 0.001. Conclusions We found a high prevalence of ocular complications among children with nephrotic syndrome in this tertiary hospital. The predictor of ocular complications was age greater than 10 years. We recommend that all children with nephrotic syndrome undergo a baseline ocular examination prior to commencement of treatment and be reviewed periodically by an ophthalmologist.
