Immunostaging was performed in patients with chronic pancreatitis of different etiologic groups. Immune responifveness was assessed by immunoglobulin serum levels, non specific autoantibody formation, C3 levels, antistreptolysin reaction, antibody titer against Toxoplasma gondii, E. coli, Herpes simplex-, Mumps- and Cytomegalovirus and screening for soluble immune-complexes (PEG precipitation assay), number of T- and B-lymphocytes, lymphocyte responsiveness to PHA, PPD, tetatoxoid and mumps-antigen in a whole blood assay, skin testing with candidin, trichophytin, tuberculin and streptokinase and HLA-typing. In some cases we found a depressed cell-mediated immune responsiveness. Patients were divided into two groups based on this main finding. Cellular hyporesponsiveness was correlated to the severity of the disease and a high incidence of HLA-B5 but not to any etiologic factor of the disease. |
