title: [The immunological changes and prognosis of cholestatic jaundice in choledocholithiasis].
abstract: Fifty-six patients presenting choledocholithiasis are covered by the study. They are distributed in groups according to total serum bilirubin values, as follows: with total serum bilirubin < 20 mumol/l--17; 20 to 50 mumol/l--13; 50 to 80 mumol/l--9; and > 80 mumol/l--17 cases. Sixty healthy, sex and age matched individuals serve as controls. The immunocompetent cells are determined flow cytometrically with FACS TAR (BECTON DICKINSON). A panel of monoclonal antibodies (Becton Dickinson) is used, including: Leu4 (anti-CD3+)--T-lymphocytes; Leu3a (anti-CD4+)--helper/inducer lymphocytes; Leu2a (anti-CD8+)--suppressor/cytotoxic cells; Leu11a (anti-CD16+)--cells with a natural killer activity; Leu12 (anti-CD19+)--B-lymphocytes. As shown by the obtained results there are no changes in cell-mediated immune response among choledocholithiasis patients with normal values of total serum bilirubin. Parallel to increasing the degree of cholestatic jaundice (ChJ) severity, the absolute values of lymphocytes and their subpopulations decrease. The deficit is most clearcut in patients presenting the highest degree cholestasis, as compared to healthy individuals ((Ly: 1690 +/- 174/2277 +/- 186; CD3+: 956 +/- 119/1793 +/- 67; CD4+: 607 +/- 83/988 +/- 80; CD8+: 239 +/- 52/639 +/- 85; CD16+: 146 +/- 38/367 +/- 55; CD19+: 181 +/- 33/200 +/- 13. In 11 cases with early restored biliary drainage (by the 21st day of ChJ), total serum bilirubin decreases within 10 days after the operation (choledochoduodenoanastomosis), whereas lymphocytes and their subpopulations show an increase in absolute values. Two months after choledochoduodenoanastomosis, the total serum bilirubin and the lymphocyte subpopulations being examined regain their normal values. In two instances with rather late biliary drainage recovery (30 days after ChJ) the total serum bilirubin and lymphocyte subpopulations under study show no tendency whatsoever towards normalization at 10 days postoperatively. The results of the study demonstrate that the poor prognosis among ChJ patients is also related to inhibition of the cell-mediated immune response. The early biliary drainage recovery (at 21 days of ChJ) exerts a more favourable effect on the immune system, and improves the prognosis of the clinical course run by the pathological process.
