The present report describes a rare case of hematophagic histiocytosis associated with acute renal failure. A 32-year-old woman was referred to us from a local hospital because of progressive deterioration of renal function, jaundice and a bleeding tendency. The physical findings at admission revealed hyperemic conjunctivae, gingival bleeding, hepatomegaly, and generalized myalgia. Laboratory data indicated a decrease in platelet count, azotemia and hyperbilirubinemia. Marked elevation of serum triglycerides and ferritin was also noted. Histiocyte proliferation with phagocytosis of erythrocytes and platelets was observed in a bone marrow aspirate. A renal biopsy specimen exhibited lesions generally observed in acute tubular necrosis: degeneration and necrosis of tubular epithelial cells; round cell infiltration and edema in the interstitium; and unremarkable glomeruli. The serum titer to coxsackievirus B1 rose from < 4x at admission to 16x after recovery from the illness, suggesting that this virus may have been the causal organism of the accompanying infection. The patient's symptoms improved rapidly with supportive therapy, and complete restoration of renal function was achieved in 20 days. The morphological characteristics of the bone marrow aspirate and the clinical course were compatible with hematophagic histiocytosis.

A 38-year-old male was admitted with fever, progressive jaundice, cervical lymphadenopathy, hepatomegaly and acute oliguric renal failure. Epstein-Barr virus (EBV) infection was diagnosed by detection of EBV-DNA in plasma and confirmed by EBV seroconversion. Kidney biopsy revealed acute tubular necrosis and abundant casts, consisting of bilirubin pigment. With conservative treatment, the patient fully recovered from cholemic nephrosis, an uncommon condition, not described after EBV infection before.

Malaria is an infectious disease of great importance for Public Health, as it is the most prevalent endemic disease in the world, affecting millions of people living in tropical areas of the globe. Kidney involvement is relatively frequent in infections by P. falciparum and P. malariae, but has also been described in the infection by P. vivax. Kidney complications in malaria mainly occur due to hemodynamic dysfunction and immune response. Liver complications leading to hepatomegaly, jaundice and hepatic dysfunction can also contribute to the occurrence of acute kidney injury. Histologic studies in malaria also evidence glomerulonephritis, acute tubular necrosis and acute interstitial nephritis. It is also possible to find chronic kidney disease associated with malaria, mainly in those patients suffering from repeated episodes of infection. Plasmodium antigens have already been detected in the glomeruli, suggesting a direct effect of the parasite in the kidney, which can trigger an inflammatory process leading to different types of glomerulonephritis. Clinical manifestations of kidney involvement in malaria include proteinuria, microalbuminuria and urinary casts, reported in 20 to 50% of cases. Nephrotic syndrome has also been described in the infection by P. falciparum, but it is rare. This paper highlights the main aspects of kidney involvement in malaria and important findings of the most recent research addressing this issue.
