[Antibodies to E. coli and circulating immune complexes in the bile and blood serum of patients with suppurative cholangitis]. / Antitela k E. coli i tsirkuliruiushchie immunnye kompleksy v zhelche i syvorotke krovi bol'nykh gnoinym kholangitom.

It has been found out for the first time that in 55% of cases presenting with purulent cholangitis, there are antibodies to a clinical strain of E. coli in the bile taken intraoperatively from major bile duct whereas museum specimens of E. coli strain are free from the above antibodies. Immune complexes were identified in the bile of all examined patients (0.316 +/- 0.085 arbitrary units). In the blood serum of patients with purulent cholangitis, antibodies to the clinical strain E. coli are not detectable, while there are great counts of circulating immune complexes (0.928 +/- 0.242 arbitrary units). Based on the findings obtained a conclusion was reached about relative independence of local immunity of the biliary tract.
