A Study on Serum Hepatic Enzymes in Smokers and Nonsmoker’s Adult Male

Background: Cigarette smoking is one of the greatest indirect causes of global death and disease. Cigarette smoke consists of many chemicals, including cytotoxic, carcinogenic and free radicals, therefore it affects many organs including liver either directly or indirectly. Objective: The aim of this study was to find out level of serum hepatic enzymes in smokers and non-smokers adult male. Method: This cross-sectional study was conducted in the Department of Biochemistry, Dhaka Medical College, Dhaka, Bangladesh, from January 2019 to December 2019. Total study subjects were one hundred and twenty with age ranging from 20 to 50 years of male gender, selected from attendance of admitted patients and third & forth class employees of Dhaka Medical College Hospital, Dhaka. Study subjects were grouped smokers as Group A and age and gender matched, nonsmokers as Group B. Group A smokers again divided into three groups. Group A1- heavy smokers (who consume 20 cigarette sticks or more per day) consist of thirty study subjects, Group A2- moderate smokers (who consume 11-19 cigarette sticks per day) consist of thirty study subjects and Group A3- light smokers (who consume 1-10 cigarette sticks per day) consist of thirty study subjects. Serum Alanine Transaminase (ALT), Aspartate transaminase (AST) and Alkaline phosphatase (ALP) level of all study subjects were estimated and recorded. Results: Mean age of the study subjects in group A1, A2, A3 & B were 33.88 years, 34.60 years, 34.60 years and 29.80 years. There was a significant increase in serum ALT, AST and ALP level in heavy, moderate and light smokers when compared to nonsmokers, but the increase was more significant in heavy smokers when compared to moderate smokers, also moderate smokers when compared to light smokers. Conclusion: This study revealed that significantly higher level of serum hepatic enzymes with smokers when compared to that of non smokers. This significantly higher level was also seen in heavy smokers in comparison to moderate smokers, moderate smokers in comparison to light smokers.
