A 12-year-old African American male with homozygous sickle cell disease (SCD) was admitted with insidious onset of periorbital and scrotal edema. The initial evaluation failed to reveal any underlying monoclonal gammopathy, or cryoglobulinemia, or other systemic causes for the renal disease. A percutaneous renal biopsy was consistent with immunotactoid glomerulopathy (ITG), which is rare in children and is characterized histologically by fibrillar deposits in the glomeruli. Children can present with symptoms of nephrotic syndrome and progress to end stage renal disease. Our patient was treated with an ACE inhibitor and is currently free of edema and with normal renal function on follow-up at 1 year. Immunotactoid glomerulopathy should be considered in the differential diagnosis of nephrotic syndrome in children with sickle cell disease. Renal biopsy is indicated in children with sickle cell disease and nephrotic syndrome and ITG should be considered as potential cause. Although there is no effective treatment for this condition, ACE inhibitors can decrease the protein-uria and possibly delay the progression to end stage renal disease. The side effects related to the use of ACE inhibitors should be monitored. These include renal impairment, hyperkalemia, anemia, neutropenia, and angioedema. Since we have a short follow-up in our patient, the role and safety of ACE inhibitors in the management of ITG need further evaluation.
