OBJECTIVE: To explore the occurrence of, and diagnostic and therapeutic procedures for urological side-effects (e.g. micro- and macrohaematuria, and kidney stone formation) in individuals treated with indinavir for the human immunodeficiency virus (HIV).
PATIENTS AND METHODS: The study comprised a retrospective follow-up of 74 individuals infected with HIV-1 and who were treated with indinavir orally at a daily dose of 2.4 g. Data were collected at the outpatient department of our institution between March 1996 and November 1997.
RESULTS: Of the 74 individuals treated with indinavir, 15 (20%) had indinavir-related urological side-effects (19 episodes), most commonly dull flank pain and dysuria. Microhaematuria occurred in 16 of the 19 episodes. Four patients showed urinary tract distension ultrasonographically as a possible indirect sign of urolithiasis and one patient passed a kidney stone. In four patients treatment had to be stopped permanently, but in the remaining 11 patients treatment was continued. Some patients required dose reduction and/or interruption of treatment; only conservative therapeutic measures were required, consisting of rehydration (fluid intake >1.5 L/day) and analgesics.
CONCLUSIONS: Urological side-effects of indinavir may be apparent in 20% of patients so treated; some (5%) may require permanent withdrawal. In addition to a history and clinical examination, urine analysis and ultrasonography were the only diagnostic procedures required. Therapy is mainly conservative, using rehydration, analgesics and a brief discontinuation of therapy, according to the severity of the symptoms.
