Background
FSGS is a common histopathologic lesion in adult patients with nephrotic syndrome. We report on one of the most extensive observational studies of FSGS to identify predictors of long-term outcomes.
Methods
Nine centers enrolled 723 patients with FSGS of primary, genetic, or unknown etiology between 01/01/2000 and 08/01/2021. The GlomCon Research Consortium developed data definitions, collection instruments and study protocol.
Results
Clinical and biopsy characteristics (Table 1) were evaluated based on treatment history. Figure 1 and Table 2 show outcomes at 1, 3, and 5 years and time to events. Several statistically and clinically significant differences exist between immunosuppressive therapy (IST) and no IST groups.
Conclusion
The overall risk of ESKD and death is substantial. Additional analysis is being conducted to identify independent factors (clinical, treatment, and biopsy characteristics) associated with patient outcomes, predictors of IST response, and those most at risk for CKD progression, ESKD, and death.
