BACKGROUND: Collapsing focal segmental glomerulosclerosis (cFSGS) is an aggressive glomerular disease presenting as a nephrotic syndrome that has lower rates of remission with conventional immunosuppressive therapy and rapidly progresses to end-stage-renal-disease (ESRD). We report eight cases of HIV-negative cFSGS treated with rituximab.
METHODS: The current report is a retrospective case series of cFSGS treated with rituximab from January 2011 to March 2020, at varying phases of the disease.
RESULTS: Eight out of the 70 cFSGS patients received rituximab. The median age of patients was 30 years (IQR 24.25-37.5); five patients were males. The median serum creatinine, mean serum albumin and median 24 hours urinary protein at presentation was 0.9 (IQR 0.66-1.27) mg/dL, 2.95 ± 1.15 g/dL, 4.87 (IQR 1.64-5.75) g/day, respectively. Two patients were steroid-resistant, one steroid and tacrolimus dependent, one steroid and cyclosporine dependent, two steroids and tacrolimus resistant, one steroid, tacrolimus, cyclophosphamide, mycophenolate mofetil resistant and one steroid-resistant and tacrolimus dependent before rituximab therapy. Rituximab was given either as targeted therapy (after an initial dose of 375 mg/m2 ; patients having CD-19 levels >5/μL or >1% at 1 month received additional low-dose [100 mg] of rituximab), or weekly regimen. Five patients received CD-19 targeted rituximab; three received weekly doses of 375 mg/m2 , cumulative doses being 820 ± 228.03 mg, and 1800 ± 721.11 mg, respectively. At the end of median follow-up of 15 months, five (62.5%) patients were in remission (three partial, two complete remissions), two (25%) were resistant to therapy; one (12.5%) progressed to ESRD.
CONCLUSION: Rituximab is reasonably safe and achieves/maintains remission in 60% of cFSGS cases.
