Two schools in rural Tanzania were surveyed regarding the pupils' nutrition (weight and height), serum immunoglobulins (IgA, IgG, IgM, and IgE), autoantibodies, @entity311 antibodies, @entity1956 . The survey attempted to quantify the relative importance of undernutrition and @entity4801 in determining the serological abnormalities found. Of all the @entity1 surveyed 69% were undernourished (less than 80% of expected weight for age); 63% had fecal parasites and 38% had @entity14454 . Serum IgG and IgM concentrations were raised and the serum IgE concentration was strikingly raised (mean 4990IU/ml). Elevated serum IgE was associated with @entity2329 . Autoantibodies were common but no @entity792 was detected. Notably there was a 35% prevalence of reticulin antibody. This reticulin antibody positivity correlated with increased @entity311 antibody concentrations. Reduced @entity311 antibody concentration was significantly associated with @entity1956 antigenemia. The study illustrates that parasites, notably @entity311 , are important determinants of the serum antibodies of @entity1 in the tropics and suggests that mild undernutrition has little effect.
