Abstract

The mechanisms by which Cryptosporidium parvum cause persistent diarrhea and increased morbidity and mortality are poorly understood. Three groups of Haitian children <18 months old were studied: case patients, children with diarrhea not due to Cryptosporidium, and healthy control subjects. Compared with both control groups, children with acute cryptosporidiosis were more malnourished (including measures of stunting [P = .03] and general malnutrition [P = .01]), vitamin A deficient (P = .04), and less often breast-fed (P = .04). Markers of a proinflammatory immune response, interleukin (IL)-8 and tumor necrosis factor-α receptor I, were significantly elevated in the case population (P = .02 and P < .01, respectively), as was fecal lactoferrin (P = .01) and the T helper (Th)-2 cytokine IL-13 (P = .03). The counter-regulatory cytokine IL-10 was exclusively elevated in the case population (P < .01). A Th1 cytokine response to infection was not detected. This triple cohort study demonstrates that malnourished children with acute cryptosporidiosis mount inflammatory, Th-2, and counter-regulatory intestinal immune responses.
