Аннотация
BACKGROUND: Hemophagocytic syndrome (HPS) is a rare, aggressive disorder characterized by dysregulation of lymphocyte and macrophage activity, which culminates in tissue infiltration with hemophagocytosis and ultimately organ failure. Renal involvement frequently ensues and usually results in acute tubular necrosis with associated interstitial inflammation. Less frequently, glomerulopathy can also be found.
CASE: We report a case of a 24-year-old Caucasian woman with previous asymptomatic hematuria, mild proteinuria, and normal renal function who presented to us with fever. Laboratory findings revealed pancytopenia, elevated lactate dehydrogenase, and ferritin as well as liver and kidney failure. Renal biopsy showed a tubulointerstitial nephritis superimposed in a membranoproliferative glomerulonephritis with crescents. Extensive etiologic investigation was negative except for Epstein-Barr virus (EBV) viral load. EBV-DNA was then identified by in situ hybridization in the renal biopsy. HPS could be diagnosed with the presence of six criteria: fever, splenomegaly, bicytopenia, high ferritin, hypertriglyceridemia, and high levels of soluble CD25. Steroid therapy was initiated with resolution of HPS as well as complete recovery of renal and liver function.
CONCLUSION: In this case, we believe that EBV triggered both HPS and tubulointerstitial nephritis. Steroid therapy successfully treated the inflammatory syndrome, allowing renal function recovery without compromising EBV infection resolution. .
