Description of intervention(s) / exposure
The exposure to be studied is primary focal segmental glomerulosclerosis (FSGS). At baseline, the demography, clinical features, investigations, renal biopsy and treatment details will be recorded in case report forms. The follow-up will be at least twice a year for 24 months. At follow-up the relevant clinical features, investigations and treatment details will be recorded in the case report forms. The duration of follow up for participants in the study is 24 months from the time of recruitment.
Intervention code [1] 299378 0
Early Detection / Screening
Comparator / control treatment
Disease control group will be adult patients diagnosed to have glomerulonephritis other than FSGS by renal biopsy. At baseline, the demography, clinical features, investigations, renal biopsy and treatment details will be recorded in case report forms. Healthy controls will be participants who have no known illnesses. There is no follow-up for the control arm.

Timepoint [3] 339745 0
Baseline
Secondary outcome [4] 344442 0
Clinical response as assessed by 24 hour urine protein and CKD-EPI eGFR (derived from serum creatinine) and classified as complete response, partial response, no response, progressive CKD stages, end stage kidney disease.
Complete response is defined as 24 hour urine protein less than or equal to 300mg per day and CKD-EPI eGFR greater than or equal to 60ml/min/1.73m2.
Partial response is defined as 50% education in proteinuria from baseline and 24 hour urine protein less than or equal to 3.5 g/day along stable CKD-EPI eGFR not more than 25% of the baseline values.
No response is defined as persistent or increasing proteinuria with stable stable CKD-EPI eGFR not more than 25% of the baseline values.
Progressive CKD stages is when the renal function worsens with or without proteinuria.
End stage kidney disease is defined as CKD-EPI eGFR less than or equal to 15ml/min/1.73m2 with or without the need for renal replacement therapy.

24 months
Secondary outcome [5] 344444 0
Describe toxicities and side effects of treatment. This will be assessed through medical records, hospital records, patient-reported, etc. The side effects that may occur are infections, steroid induced diabetes, Cushing's etc.

Statistical methods / analysis
Sample size- Since this is an exploratory study, there is no formal sample size calculation. It is a pilot study that will give us important pathogenetic information for planning further large cohort studies. We will be recruiting 50 biopsy proven FSGS subjects with 20 disease and 20 healthy controls. Twenty healthy people will serve as controls for standardization of test results. Twenty disease controls (non-FSGS primary glomerulonephritis) will be recruited as controls for changes in biomarkers due to renal impairment and proteinuria.

Statistical Analysis- Categorical baseline characteristics (e.g. sex, race, co-morbid illnesses, etc) will be expressed with the number and percent of subjects in each treatment group. Quantitative characteristics (e.g., age and weight) will be summarized by mean and standard deviation or median [inter quartile range], depending on data distribution. The number and percent of subjects will be provided for each reason for premature discontinuation. Differences in proportions will be evaluated by chi square or Fisher’s exact tests. Comparisons between groups will be performed using Student's t-test or the Mann-Whitney U test depending on the data distribution. Correlation between treatment and clinical response will be done with tests as described above. The risk factors for progressive disease will be evaluated using a Cox proportional hazard model with a stepwise backward elimination method.
