Effects of Laparoscopic Cholecystectomy on Mucin1 and Cholesterol Ester Transfer Protein Status in Bangladeshi patients with Cholelithiasis

Abstract

Objective: Although it was reported that cholecystectomy had profound impact on lipid profile and lipoprotein (a) status, no studies were reported on Mucin1 and cholesterol ester transfer protein (CETP) in Bangladeshi patients with cholelithiasis i.e. gallstone disease (GD). The present study was done about effects of laparoscopic cholecystectomy on Mucin1 and CETP status in Bangladeshi patients with cholelithiasis.Patients & Methods: Forty-four adult GD patients with cholelithiasis and 30 normal controls (NC) subjects were included in the study. The blood was taken from fasting patients before cholecystectomy (Serum-I°), gall bladder bile during cholecystectomy (Bile-I°) and blood again after 2-3 months at follow-up (Serum-II°) and from fasting NC subjects. Mucin1 and CETP levels were quantified in serum and bile by enzyme immunoassay (EIA) method using commercially available research kits. The results were compared by appropriate statistical tests using SPSS program.Results: Serum levels of both Mucin1 and CETP were increased in Pt-I°(S) compared to NC-I°(S) which were reduced after cholecystectomy in Pts-II°(S). However, serum CETP mean level in Pts-I°(S) was not significantly higher than NC-I°(S).The Mucin1 and CETP levels in patients bile, i.e. Pt-I°(B), were lower compared to serum levels before, Pt-I°(S), and after, (Pt-II°(S), cholecystectomy [Mucin1 (ng/ml): Pts-I°(S): 10.77 ± 2.93, Pts-I°(B): 1.29 ± 1.21, Pts II°(S): 6.67 ± 2.03, NCs(I°): 4.63 ± 0.53; CETP (μg/ml): Pts-I°(S): 11.47 ± 5.04, Pts-I°(B): 1.16 ± 1.19, Pts-II°(S): 9.41 ± 2.42, NCs (I°): 9.57 ± 3.63] . A significantly large proportion of patients had higher levels of Mucin1, but large number of patients had CETP levels within the normal range in Pt-I°(S). Interestingly, this was changed after cholecystectomy that significant proportion of patients had higher CETP levels in Pt-II°(S).Conclusions: Alterations in serum Mucin1 and CETP status were significant but complex and laparoscopic cholecystectomy had significant impact indicating an important function of gallbladder relevant to their metabolism. Further studies are needed on prevalence and frequency of metabolic syndrome, insulin resistance, cytokines and other relevant parameters in Bangladeshi patients with GD i.e. cholelithiasis.
