Objectives: To describe the unusual occurrence of systemic lupus erythematosus (SLE) with nephritis in human immunodeficiency virus (HIV)-infected individuals.
Methods: Chart review-based report of a case of SLE with diffuse proliferative glomerulonephritis (DPGN) in an HIV-infected man, together with a literature review of previously published cases. We searched the English language medical literature from 1987 to 2009 using the following PubMed and Medline terms: "SLE," "HIV," "DPGN." In addition, we researched the role of mycophenolate mofetil (MMF) in the treatment of patients with HIV by using the keywords "MMF" and "HIV".
Results: An 18-year-old male patient with vertically transmitted HIV-1 infection presented with malaise, weight loss, malar rash, arthritis, proteinuria, and hematuria. Kidney biopsy confirmed the diagnosis of lupus nephritis (Class IV). He was treated successfully with high-dose corticosteroids and MMF, which were added to his baseline treatment of highly active antiretroviral therapy. The review of the literature identified a total of 18 cases of SLE appearing in HIV+ individuals, of which 11 patients had lupus nephritis. Among the latter, there were only 5 cases of proliferative (focal or diffuse) glomerulonephritis, and their treatment consisted mainly of high-dose corticosteroids. The short-term outcome was favorable in 4 cases and 1 patient died.
Conclusions: Proliferative lupus nephritis is rare in HIV-infected patients. A detailed analysis of the cases may lead to important insights into the pathogenic mechanisms of both diseases. Considering its complex interaction with antiviral medications, MMF may be considered for the treatment of lupus with severe proliferative glomerulonephritis in HIV-infected individuals.
