Risk factors for relapse in childhood steroid sensitive nephrotic syndrome
Journal Title: Indian Journal of Child Health - Year 2017, Vol 4, Issue 3
Abstract
Background: Nephrotic syndrome (NS) generally tends to follow a benign and chronic relapsing course. Relapses are a major problem in children with steroid sensitive NS (SSNS). Objective: To identify the risk factors for frequent relapse (FR) in the first episode childhood SSNS. Methods: This prospective study was conducted in the Government Dharmapuri Medical College Hospital, Tamil Nadu, between July 2013 and January 2016. Children aged 9 months - 12 years with a diagnosis of SSNS (first episode) who came for follow-up for at least 12 months in the pediatric nephrology clinic were included. The enrolled cases were divided into 2 groups: (1) frequent relapser (FR) and (2) infrequent relapser (IFR). 9 factors were studied as possible risk factors for relapse. The data collected were analyzed using Chi-square test and Student’s t-test. Results: Of 160 SSNS children, there were 92 (57.5%) cases of IFR and 68 (42.5%) cases of FR. There were 97 males (60.6%) and 63 females (39.4%) with a male to female ratio of 1.5:1. The mean age of presentation was 4.37±2.32 years. The mean time taken to achieve remission during the first episode was 1.94±1.04 weeks. The interval between remission and first relapse was 5.56±4.51 months. Incidence of infection and hypertension was 31.9% and 37.5%, respectively. Risk factors significantly associated with FR were: Time taken to achieve remission during the first episode (>14 days) (p<0.0001), mean duration of interval between remission and first relapse (within 6 months) (p<0.0001), associated infections (p<0.0001) and hypertension (p<0.0001). Age at onset, sex, serum albumin, 24 h urine protein, and azotemia did not influence the FR in our study. Conclusion: More than 14 days to achieve remission during the first episode, relapse within first 6 months, associated infections and hypertension were the factors associated with FRs.
