Abstract 192P


Experimental and clinical studies have shown an increase in the level of interleukin-6 (IL-6) in the blood plasma and other cytokines in obstructive jaundice. The combination of a persistent increase in cytokines and an extended acute response phase is associated with a decrease in protein calories, leading to surgical complications and death.


The study involved 41 patients treated at the Gastroenterology department in 1st Republic Clinic, Tashkent aged from 33 to 84 years old (62.8 ± 2.14) were studied, of whom 26 (63.4%) were men and 15 (36.6%) were women. The duration of the icteric period by the time of admission to the hospital averaged 28.7 ± 2.18 days. At the same time, in 6 (14.6%) patients the duration of cholestasis was up to 15 days, in 10 (24.4%) - from 15 to 30 days, in 25 (61.0%) - more than 1 month. Percutaneous transhepatic cholangiography (PTCH) with per-cutaneous transhepatic cholangiostomy (PTCHS) was performed for all patients, regardless of the localization of the tumor process. The level of IL-6 in serum and bile was determined by ELISA method.


The concentration of IL-6 before the overlap of PTCH in the serum was higher than normal, averaging 152.65 ± 16.3 pg/ml. Immediately after the overlaying of PTCH in bile, this indicator was on average 68.58 ± 7.24 pg/ml. The high content of IL-6 in serum and bile testified to a pronounced endogenous intoxication of the body. The concentration of IL-6 in the initial day after the imposition of PTCH in serum decreased to 32.9%. In the following days, this indicator remained virtually unchanged, but on the 6th day of observation, there was a slight increase in his blood. In the bile at the same time, the concentration of IL-6 decreased by 17.1%. These indicators remained virtually unchanged up to 6 days of observation. On the 14th day, the decrease in the level of IL-6 in the blood compared to baseline was 64.4%, and in the bile 54.3% (P < 0.001).


Thus, the determination of IL-6 in the blood and in the bile makes it possible to more objectively evaluate the tumor process and the cytokine-induced endogenous intoxication to the response of the therapeutic measures taken in biliopancreatoduodenal tumors complicated by the mechanical jaundice.
