Longitudinal study of glomerular hyperfiltration in adults with sickle cell anemia: a multicenter pooled analysis.

ABSTRACT: Glomerular hyperfiltration is common in young sickle cell anemia patients and precedes development of overt kidney disease. In this multicenter pooled cohort, we characterized hyperfiltration and its decline to normal range in adult patients. Glomerular filtration rate (GFR) was estimated using the creatinine-based 2009 CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) equation omitting race adjustment and the 2021 CKD-EPI equation. Using CKD-EPI-2009, 506 patients had baseline estimated GFR (eGFR) ≥90 mL/min per 1.73 m2, median age of 24 (interquartile range [IQR], 19-34) years and 5.17 years of follow-up. The prevalence of hyperfiltration (eGFR ≥140 and ≥130 mL/min per 1.73 m2 for men and women, respectively) was 38.3%. Using CKD-EPI-2009, baseline hyperfiltration was less like
