Aim: To investigate the proportion of patients with alcoholic cirrhosis who abstained from alcohol after contact with a hepatology unit, the predictors for abstinence, and the role of clinical and psychosocial factors in short-term mortality in these patients.
Methods: Eighty-seven consecutive patients with alcoholic cirrhosis from a transplant center were included. Data on cirrhosis severity and complications, as well as on abstinence and psychosocial factors were collected. Patients were followed up for 19 (12–25) months. Data on abstinence during follow up, alcohol abuse treatment, psychiatric contact, severity of cirrhosis, mortality, and liver transplantation were analyzed.
Results: Prior to inclusion, 53/87 (61%) patients had abstained from alcohol for 24 months (interquartile range: 18–33). Twenty percent had a history of other substance abuse, 47% had undergone alcohol abuse treatment, and 21% had a previous psychiatric diagnosis. Forty-eight percent lived with a partner, 23% worked/studied, and 53% were pensioners. During follow up, 26% died, 20% received a liver transplant, 55% abstained from alcohol, 47% received alcohol abuse treatment, and 33% had psychiatric contact. In a multivariate analysis, abstinence during follow up was found to be related to abstinence upon inclusion in the study, to the model for end-stage liver disease (MELD) score at follow up, and to no abuse treatment in a detoxification unit, whereas mortality was related to index MELD and alcohol abuse treatment during follow up. Neither abstinence nor mortality was related to psychosocial factors.
Conclusion: More than half of patients with alcoholic cirrhosis were found to abstain from alcohol during follow up, which was related to prior documentation of abstinence and cirrhosis severity. Cirrhosis severity (expressed as the MELD) and alcohol abuse treatment during follow up were related to short-term mortality. 相似文献
