A 41-year-old woman with a myelodysplastic syndrome complained of diarrhea with malabsorption and protein-losing enteropathy after splenectomy. No cause was found and various therapeutic regimens were not effective. Pathological examination of biopsies from stomach, small intestine, and large bowel showed infiltrations interpreted as inflammatory on routine technics. Blast cell infiltration was found on electron microscopy. Treatment by citarabine induced normalization of leukocytosis, and diarrhea disappeared. Six months after the onset of illness, she developed acute myeloblastic leukemia and died of infectious pneumonia. Blastic infiltration of the lamina propria could be responsible for the determinism of symptoms, because of the lack of another etiology, the intensity of the blastic infiltration and the effect of cytotoxic therapy, even in the absence of new biopsies.

Using multivariate techniques, we studied the relationships of cytotoxic regimen, intestinal mucosal damage, and fungal colonization in the pathogenesis of invasive fungal disease in 138 patients undergoing induction therapy for untreated acute myeloid leukemia (AML) according to three institutional protocols: AML-84 (cytarabine/daunorubicin), AML-87 (high-dose cytarabine/etoposide/daunorubicin), and AML-88 (mitoxantrone/etoposide). Invasive fungal disease occurred in 36%, 6%, and 2.6% of patients participating in protocols AML-87, AML-84, and AML-88, respectively (chi 2 = 23.465; P < .0001). Protocol AML-87 was the strongest independent predictor in the multivariate model (RR = 26.7; P < .0001). Cytotoxic therapy-related epithelial damage in the gut, as measured by D-xylose malabsorption, correlated with invasive fungal disease and protocol AML-87. Fungal colonization, a predictor of invasive fungal disease, correlated with frequent modifications of antibiotic regimens. These results demonstrate the role of cytotoxic regimen-related gut epithelial damage, antibiotic-prescribing behavior, and fungal colonization in the pathogenesis of invasive fungal disease in patients with leukemia.
