[Sepsis by Candida tropicalis in patients with granulocytopenia. A study of 10 cases].
The aim of the present study was to analyze the main clinical and evolutive characteristics of a series of 10 patients diagnosed with sepsis by Candida tropicalis over a 5-year period in a Hematology Unit. The mean age of the 10 patients was 23 years (range 13-66 years) with 6 males and 4 females. Eight patients had acute leukemia, 1 non-Hodgkin's lymphoma and another patient had severe bone marrow aplasia. All the patients presented intense granulocytopenia (< 0.5 x 10(9)/L), had intravenous catheters and were receiving wide spectrum antibiotics as treatment for bacterial infection. The diagnosis of the fungal infection was based on the growth of C. tropicalis in blood cultures together with the evidence of tissue involvement by the fungus. Fever (> 38 degrees C) was the initial symptom of the infection in all the patients, being accompanied by myalgia in 5 cases, pleuritic pain in 2 and septic shock in 1. Violaceous erthymatomous pustules disseminated over the trunk and limbs, the histologic study of which demonstrated the presence of C. tropicalis were observed in 9 patients. Septic metastasis were found in the liver (2 cases), serosae (2 cases), the psoas muscle and the brain (1 case), respectively. Eight patients underwent treatment with amphotericin B which was complemented with 5-fluorocytosin in 6, with death occurring in the remaining 2 patients prior to the start of treatment. Three patients died with active fungal infection (2 by cerebral hemorrhage and 1 by septic shock). In 2 patients the infection evolved to chronic systemic candidiasis and in the remaining 5 patients infection was resolved with hemoperipheral values returning to normal. Sepsis by Candida tropicalis is a severe complication in patients with granulocytopenia, being mainly characterized by fever, cutaneous papulae and, to a lesser extent, muscle pain. Amphotericin B alone, or in combination with 5-fluorocytosin constitute a treatment of choice in this infection, which nonetheless is associated with an undisdainful mortality.
