Complement alterations in inflammatory bowel disease.

A prospective evaluation of the activity of the complement system was undertaken in 32 patients at the time of diagnosis of inflammatory bowel disease, before the onset of therapy. Serum classical pathway components and function were normal, while significant abnormalities of the alternative pathway were found. Depressions of serum properdin and properdin convertase were noted in association with diminished consumption of C3--C9 after reaction with cobra venom. These abnormalities of alternative pathway integrity were most significant in regional enteritis and in ulcerative colitis with extraintestinal complications. Sequential studies extending into clinical remission revealed resolution of all significant abnormalities.

Serum complement concentrations, nutritional status and the outcome of measles and measles pneumonia.

A prospective study of children with measles has shown a significant association between malnutrition and a poor prognosis. Levels of a number of complement components bore no relationship to the severity of the disease or to its prognosis. Some of the children with acute measles had depressed serum concentrations of factor D, Clq or C3, but complement deficiency does not appear to be implicated in the heightened susceptibility to secondary bacterial and viral infection so commonly found after acute measles.
