Abstract
Mucosal and systemic immune systems are quite separate in their proper ties and in the factors which regulate them. In man, assessment of imm une status at gut level, including the capacity to respond to oral vac cines, should follow the general lines which are used in research and clinical investigation of systemic immunity. All of the currently avai lable methods for direct studies of gut immunity have limitations, but a new technique, per-oral whole gut lavage with non-absorbable cleans ing fluid, provides a system of gut perfusion. The value of this techn ique is illustrated by data on intestinal antibodies to bacterial LPS core antigens, of gut immunity in healthy African children, on the iso type of antibodies elicited by oral killed whole cell/cholera toxin B vaccine in coeliac disease patients, and on the effects of smoking on intestinal antibodies elicited by the oral typhoid vacine Ty21a in hea lthy UK adults. Finally, results of a recent comprehensive study show that immunological tests using faeces are likely to be highly misleadi ng.
