Use of decline in D-xylose absorption to predict infection following intensive chemotherapy

Abstract

Oral D-xylose absorption and urinary excretion were measured before and after 32 courses of intensive chemotherapy in 14 patients with acute leukemia in complete remission. The incidence of severe and life-threatening infectious complications was greatest in those patients in whom the absorption and excretion of D-xylose fell below normal immediately following 4-7 days of chemotherapy. Gram-negative bacilli and staphylococci were the most common organisms to cause bacteremia in these patients.
