title: Resolution of nephrotic syndrome and lack of progression of heroin-associated renal amyloidosis.
abstract: The case of a patient with nephrotic syndrome and renal insufficiency due to renal amyloidosis secondary to chronic subcutaneous heroin abuse who discontinued her drug habit is reported. During the 6 years following the initial renal biopsy, the patient's nephrotic syndrome remitted: urinary protein decreased from 6.8 g/d to 170 mg/d, serum albumin increased from 2.5 g/dL to 3.9 g/dL, and she was no longer edematous. Serum creatinine remained stable at 1.8 mg/dL and creatinine clearance was also unchanged at 34 mL/min. Repeat renal biopsy showed AA amyloidosis involving the glomeruli, with minimal interstitial inflammation. This appears to be the first case of clinical improvement in heroin-associated renal amyloidosis after cessation of drug injections. As in other cases of AA amyloidosis that have improved, the clinical picture does not correlate with the findings on renal biopsy.
