Abstract
Objective: To review the disease course in patients with steroid
sensitive nephrotic syndrome (SSNS) and the factors that
determine outcome
Design: Retrospective, analytical
Setting: Pediatric Nephrology Clinic at referral center in North
India
Participants/patients: All patients with SSNS evaluated between
1990 and 2005
Intervention: None
Main outcome measures: Disease course, in patients with at
least 1-yr follow up, was categorized as none or infrequent
relapses (IFR), frequent relapses or steroid dependence (FR),
and late resistance. Details on complications and therapy with
alternative agents were recorded.
Results: Records of 2603 patients (74.8% boys) were reviewed.
The mean age at onset of illness and at evaluation was 49.7±34.6

and 67.5±37.9 months respectively. The disease course at 1-yr
(n=1071) was categorized as IFR in 37.4%, FR in 56.8% and late
resistance in 5.9%. During follow up, 224 patients had 249
episodes of serious infections. Alternative medications for
frequent relapses (n=501; 46.8%) were chiefly cyclophosphamide
and levamisole. Compared to IFR, patients with FR were younger
(54.9±36.0 vs. 43.3±31.4 months), fewer had received adequate
(≥8 weeks) initial treatment (86.8% vs. 81.7%) and had shorter
initial remission (7.5±8.6 vs. 3.1±4.8 months) (all P<0.001). At
follow up of 56.0±42.6 months, 77.3% patients were in remission
or had IFR, and 17.3% had FR.
Conclusions: A high proportion of patients with SSNS show
frequent relapses, risk factors for which were an early age at
onset, inadequate initial therapy and an early relapse.
