A patient with newly-diagnosed HIV infection and biopsy-proven cerebral toxoplasmosis was treated with sulphadiazine and pyrimethamine. Despite adequate hydration and daily examination of urine for sulphadiazine crystals obstructive uropathy due to bilateral ureteric stones with hydronephrosis occurred, resulting in rapid onset renal failure. Sulphadiazine was discontinued and clindamycin was substituted. With intravenous fluid hydration and bilateral nephrostomies the urolithiasis resolved. This case serves to remind clinicians of the need for vigilance when treating cerebral toxoplasmosis with sulphadiazine, in order to avoid this potentially serious complication of treatment.

In the aging human immunodeficiency virus (HIV)-infected population with improved immune function under antiretroviral treatment, many different opportunistic disorders may be encountered, along with rare presentations or complicated forms of common diseases. Renal and urologic abnormalities observed in the setting of HIV infection or acquired immunodeficiency syndrome are reviewed with their imaging appearances, including renal dysfunction, urolithiasis, urinary tract infections and related complications, genitourinary tuberculosis, vascular lesions, urogenital tumors, and bladder abnormalities, with emphasis on characterization. In HIV-positive patients, early cross-sectional imaging is warranted to detect uncommon disorders and complications, with the aim to preserve renal function.

Atazanavir sulfate, an azapeptide inhibitor of HIV protease, has been associated with urolithiasis. A 60-year-old man with atazanavir-induced urinary sediment crystals verified by infrared spectroscopic analysis is described. He had been receiving highly active antiretroviral therapy (HAART) for HIV infection and also had a history of urinary lithiasis and been undergoing urinalysis once every month. Needle-shaped crystals were seen in his urine sediment and infrared spectroscopic analysis revealed that these were atazanavir crystals. Because the presence of the crystals in urine do not always reveal an abnormality in the urinary test strip analysis, the urinary sediment needed to be observed microscopically in order to prevent future urolithiasis and renal failure in this HIV patient receiving atazanavir.

Drug-induced renal calculi represent 1-2% of all renal calculi. In the last decade, drugs used for the treatment of HIV-infected patients have become the most frequent cause of drug-containing urinary calculi. Among these agents, protease inhibitors (PIs) are well known to induce kidney stones, especially indinavir and atazanavir, and more recently darunavir. Urolithiasis attributable to other PIs has also been reported in clinical cases such as those during non-PI use. Antiretroviral drug-induced calculi deserve consideration because most of them are potentially preventable. This article summarizes the diagnosis, epidemiology, prevention and management of antiretroviral drug-induced urolithiasis.

Kidney diseases in human immunodeficiency virus (HIV)-infected patients are often misdiagnosed. Despite reductions in morbidity and mortality owing to widespread use of highly effective combination antiretroviral therapy (cART), acute kidney injury (AKI) and chronic kidney disease (CKD) are still more common in these patients than in the general population, and are associated with poor health outcomes. HIV-associated nephropathy and HIV immune complex kidney diseases are the more recognizable HIV-related kidney diseases. However, a broad spectrum of kidney disorders related or not directly related with HIV infection can be observed, including cART-induced AKI, CKD, proximal tubular dysfunction, crystalluria and urolithiasis, among others. This review summarizes the major epidemiologic studies of kidney diseases in HIV-infected patients, discusses novel approaches that may potentially limit nephrotoxicity such as the use of tenofovir alafenamide, and outlines current screening measures for early diagnosis of kidney dysfunction or tubular damage, and for accurate detection of increased risk for acute or chronic kidney diseases.
