Results: Comparative analysis of
CASP3 levels in patients of the study groups revealed that the level of this
indicator in the blood and bile of group A patients was statistically significantly higher compared to group B, p=0,004 and p<0,001, respectively. There was no statistically significant difference between the study groups in the intraoperative levels of blood serum Bcl-2 (p=0,786) and bile Bcl-2 (p=0,439). The presence of a correlation between apoptosis markers in group A patients with I and II degree of PAC at the time of PBD and the main surgical intervention was determined: blood serum
CASP3 - r=0,733, p<0,001 and r=0,753, p<0,001; bile
CASP3 - r=0,716, p<0,001 and r=0,792, p<0,001; blood serum Bcl-2 - r=0,609, p<0,001 and r=0,495, p=0,002; bile Bcl-2- r=0,744, p<0,001 and r=0,497, p=0,002, respectively. Binary logistic regression analysis showed that the development of grade I and II PAC did not relate with the levels of apoptosis markers (p>0.05). Linear regression analysis revealed a correlation between the levels of Bcl-2 in bile during PBD and intraoperatively in group A patients with moderate grade OJ (R2=0,547, p<0,001) and between the levels of
CASP3 in blood serum (R2=0,614, p<0,001),
CASP3 in bile (R2=0,603, p<0,001), Bcl-2 in blood serum (R2=0,484, p<0,001) and Bcl-2 in bile (R2=0,485, p<0,001) in PBD and intraoperatively in patients with severe grade OJ. A statistically significant difference in the levels of Bcl-2 in blood serum (p<0,001) and Bcl-2 in bile (p=0,016) was found when comparing apoptosis markers in patients with moderate grade OJ of the study groups. Binary logistic analysis showed that the performance of PBD had a significant (reducing) effect on
CASP3 levels in blood serum and bile taken intraoperatively in study groups patients with moderate grade OJ (R2= 0,292, p<0,001; R2= 0,184, p<0,001).
