Abstract
Background
Relapses of nephrotic syndrome are common and are treated with a course of prednisolone (2 mg/kg/day or 60 mg/m2/day). This is associated with major adverse effects including diabetes, weight gain, hypertension and behavioural problems. This study is a retrospective review examining the success of treating relapses in steroid-sensitive nephrotic syndrome (SSNS) with low-dose prednisolone and the consequences on subsequent relapse rates. Furthermore, a follow-up study looked at the side-effect profile during treatment with high- versus low-dose prednisolone.
Methods
Between January 2012 and July 2013, all well children with SSNS presenting with a relapse were advised to start 1 mg/kg prednisolone daily for a maximum of 7 days. In July 2015, we compared the side-effect profile of prednisolone therapy using the parent proxy PedsQL questionnaire for quality of life (QoL).
Results
Fifty patients were included in the study, with a total of 87 relapses. Sixty-one of the 87 relapses (70 %) responded within a week. Treating relapses with a reduced dose of steroids did not adversely affect the relapse rate in the 6 months preceding and following the current relapse (1.01 vs 0.86, p = 0.3). Fifteen parents completed the PedsQL questionnaire. Comparison of scores in each category showed significantly higher values in each domain during treatment with low-dose prednisolone compared with high-dose treatment (35.6 vs 18.3, p < 0.0001; 31.1 vs 15.0, p < 0.001; 38.3 vs 20.1, p < 0.0001).
Conclusion
A low-dose prednisolone regimen was successful in achieving remission in 70 % of relapses of children with SSNS, without adversely affecting the relapse rate. Parent-completed QoL questionnaires showed significantly higher scores on low-dose treatment, indicating better QoL.
