BACKGROUND: Alcohol consumption is a well-known risk factor for elevated ALT levels, but the role of cigarette smoking is unclear. METHODS: We collected a cross-sectional sample of 6095 inhabitants 35 years or older in a community with hyperendemic hepatitis B and C virus infections. We assayed levels of serum alanine aminotransferase (ALT), hepatitis B surface antigen (HBsAg), and anti-hepatitis C virus antibody (anti-HCV). Multivariate logistic regression was performed to determine the factors for elevated ALT levels (> or =40 U/L) among people with different hepatitis infection statuses. RESULTS: Prevalence of elevated ALT levels in individuals who were seronegative for both infections or seropositive for HBsAg or anti-HCV was 3.9%, 11.1%, and 30.8%, respectively. Subjects with elevated ALT levels were more likely to be seropositive for anti-HCV, male, and seropositive for HBsAg; to drink alcohol; to smoke; and to have undergone blood transfusion (P<.05). An association was found between elevated ALT levels and the consumption of cigarettes and alcohol among anti-HCV-seropositive subjects. In multivariate logistic analyses, alcohol consumption (odds ratio [OR], 2.2; 95% confidence interval [CI], 1.2-4.1) and smoking (OR, 1.8; 95% CI, 1.1-2.7) were significantly associated with elevated ALT levels among anti-HCV-seropositive subjects, but no such association was found among HBsAg-seropositive subjects. The odds of elevated ALT levels were 7 times higher (95% CI, 2.7-18.8) for the anti-HCV-seropositive patients who smoked 1 or more packs of cigarettes per day and frequently drank alcohol than for those who did not. CONCLUSIONS: Smoking and alcohol consumption are independently associated with elevated ALT levels among anti-HCV-seropositive individuals but not among HBsAg-seropositive individuals. Patients who are seropositive for anti-HCV are strongly advised not to smoke and drink alcohol to reduce the possible risk for aggravating the liver dysfunction.

http://www.patient.co.uk/showdoc/27001174/ this is a site for a new stop smoking does not contain nicotine I have been looking at the side affects it is processed through the kidneys too Champix is the brand name Varenciline is the drug cuts the desire to smoke the biggest sx is nausea but worth a try may help him cut down and it is just another pill so he maybe wouldn't notice ask your doctor My GI recommended it for my bad smoking habit going to buy it soon

I have heard some good things about hypnotism, not sure if it would work or no. I have heard good and bad about it. There is also a drug out I think the one baja said, Others have used it, (not HCvers) I would really do some homework on it and the drugs he is taking.
Accupunture I don't know, I sort of worry about getting stuck with needles, though I am sure they autoclave before re used.
Best of luck. Deb

Hopefully after TX I can take the get healthy approach to life and quit this nasty habit!!!
Good luck

Cigarette Smoking, Hepatitis C Virus Synergistic in Raising Liver Cancer Risk
NEW YORK NOV 19, 2008 (Reuters Health) - There appears to be a synergistic link between smoking and hepatitis C virus (HCV) infection, leading to a more than 136-fold increased risk of hepatocellular carcinoma (HCC) in men, according to a team at The University of Texas MD Anderson Cancer Center.
Dr. Manal M. Hassan and colleagues in Houston also found a link between HCV, heavy alcohol consumption and HCC in women.
Dr. Hassan's team conducted a case-control study of 319 HCC patients and 1,061 healthy controls to evaluate the effects of active and passive smoking on risk factors for HCC in men and women.
The use of smokeless tobacco, cigars and pipes, and passive smoking exposure were not related to HCC among noncigarette smokers.
However, regular cigarette smoking was associated with HCC in men, with an adjusted odds ratio (AOR) of 1.9. Heavy alcohol consumption was associated with HCC in women, with an AOR of 7.7.
Co-infection with HCV increased risk of HCC exponentially. "Cigarette smoking interacted synergistically with chronic infection of hepatitis C virus in men," Dr. Hassan's team reports in the October 15 International Journal of Cancer. They found an AOR of 136.3 for HCC for male smokers with HCV infection.
Women chronically infected with HCV who were heavy drinkers had an AOR of 13.7 for HCC.
"We conclude that sex differences were observed in HCC's relationship with cigarette smoking and alcohol consumption," the authors write. "Controlling smoking exposure might be a prudent approach to the prevention of HCC, especially in patients with chronic viral hepatitis infections."
