ABSTRACT
OBJECTIVE: To determine the prevalence of impaired growth parameters (height and BMI z scores) among adolescents aged 10-19 years, with onset of idiopathic nephrotic syndrome between the age of 1 and 6 years. METHODS: A cross-sectional study was conducted among adolescents aged 10-19 years with onset of idiopathic nephrotic syndrome between the age of 1-6 years, and under regular follow-up at our center. The data were retrieved for a 10-year period (2012-2022). The current weight, height and body mass index (BMI) were recorded and interpreted as per world Health Organization (WHO) growth standards. RESULTS: 116 adolescents [60 Frequently relapsing nephrotic syndrome (FRNS)/Steroid dependent nephrotic syndrome (SDNS), and 56 Steroid resistant nephrotic syndrome (SRNS)] patients were enrolled with median (IQR) age of 133 (120,168) months and age at disease onset of 48 (26,68) months. The proportion of children with overweight (BMI for age >1z and cushingoid features), obesity (BMI for age >2z), stunting (height for age (HFA) <2z), and severe stunting (HFA <3z) were 29 (25%), 3 (2.6%), 31 (26.7%), and 7 (6%), respectively. The median (IQR) cumulative steroid dose for FRNS/SDNS and SRNS group was 19986.96 (14597.1, 26181.96) mg/m2 and 14385 (10758.82, 21355.95) mg/m2, respectively (P=0.003). CONCLUSION: The proportion of short stature and overweight was high among adolescents with nephrotic syndrome, emphasizing the need for measures to reduce steroid use and other measures to support growth.
