PG - 110-4 LID - 10.1038/ncpneph0674 [doi] AB - BACKGROUND: A 58-year-old African American man with an uncontrolled HIV infection presented to hospital with nephrotic syndrome and diffuse lymphadenopathy. The patient had been taking highly active antiretroviral therapy (HAART; lamivudine, abacavir, fosamprenavir and ritonavir) for 10 years. A renal biopsy showed acute granulomatous interstitial nephritis. Despite a negative tuberculin skin test, he was treated with antituberculosis drugs for 12 months without improvement of his renal profile. Two months after antituberculosis treatment was discontinued, the patient was readmitted to hospital because of acute renal failure. Corticosteroid therapy (prednisone) was started and resulted in a marked improvement in renal function. However, 18 months after steroids were discontinued, renal function declined dramatically. Furthermore, the patient had CD8+ lymphocytosis as well as interstitial tissue infiltration by CD8+ T lymphocytes. INVESTIGATIONS: Physical examination, plasma HIV viral load, lymphocyte counts, urinalysis, tuberculin skin test, liver function tests, renal ultrasonography, human leukocyte antigen (HLA) typing, renal and minor salivary gland biopsies, ophthalmological examination, chest radiography and culture of bronchoalveolar lavage fluid. DIAGNOSIS: Acute granulomatous interstitial nephritis secondary to diffuse infiltrative lymphocytosis syndrome. MANAGEMENT: HAART and prednisone.
