Toxoplasmosis-associated hemophagocytic syndrome in renal transplantation.
Toxoplasmosis is an infrequent, often difficult to diagnose and potentially lethal disease in kidney transplant recipients. Among reported cases, a few were associated with hemophagocytic syndrome (HPS), a rare condition characterized by widespread proliferation of macrophages phagocytizing blood elements, accompanied by fever and pancytopenia. We report here the case of a patient who received a Toxoplasma gondii positive kidney allograft and developed invasive toxoplasmosis 10 days after surgery, with high fever, skin rash, arthralgias, and renal failure, followed by pneumonia, anemia, thrombocytopenia, liver dysfunction, and encephalitis. Mislead by the absence of Toxoplasma on blood smears, alveolar fluid, renal graft biopsy, and negative brain computed tomography, confusion with serum sickness, and simultaneous herpetic infection, we failed to make the right diagnosis and the patient died with septic shock 11 days later. An HPS was revealed by a late bone marrow analysis. This may well be the fourth case ever reported of toxoplasmosis-associated HPS in renal transplant recipients.
