PG - 667-9 LID - 10.1007/s00467-011-2069-5 [doi] AB - BACKGROUND: Up to 50% of patients with severe immune deficiency experience an excessive inflammatory response called immune reconstitution inflammatory syndrome (IRIS) after the initiation of antiretroviral therapy (ART). IRIS has been observed after various opportunistic infections with pathogens such as mycobacteria, including Bacille Calmette-Guerin, cryptococci, human herpesvirus-8, non-Hodgkin's lymphoma, and progressive multifocal leukoencephalopathy. Non-acquired immune deficiency-defining illnesses can also deteriorate after commencement of ART. Renal IRIS has been reported in a few patients with mycobacterial infections, but to the best of our knowledge no cases of nephrotic syndrome and IRIS have been described. CASE-DIAGNOSIS/TREATMENT: We report the case of an infant with human immunodeficiency virus-1 (HIV-1) infection, Pneumocystis pneumonia, and encephalopathy. During immune reconstitution the patient developed nephrotic syndrome. Treatment of nephrotic syndrome was initiated with prednisone, an angiotensin-converting enzyme inhibitor (lisinopril), and low-molecular-weight heparin. ART was continued, but only a low level of lopinavir/ritonavir could be achieved. There was no relapse of nephrotic syndrome during 10 months of follow-up. CONCLUSIONS: Nephrotic syndrome may occur in infants during immune reconstitution and should not be overlooked.
