Alcohol abstinence

The efficacy of acamprosate in promoting abstinence has not been demonstrated in subjects who have not undergone detoxification and not achieved alcohol abstinence prior to beginning acamprosate treatment. The efficacy of acamprosate in promoting abstinence from alcohol in polysubstance abusers has not been adequately assessed. 

The mechanism of action of acamprosate in the maintenance of alcohol abstinence is not completely understood. Chronic alcohol exposure is hypothesized to alter the normal balance between neuronal excitation and inhibition. Studies suggest acamprosate may interact with glutamate and gamma-aminobutyric acid (GABA) neurotransmitter systems centrally, and have led to the hypothesis that acamprosate restores this balance. 

Maintenance of alcohol abstinence in alcohol-dependent patients who are abstinent at initiation of treatment PO Two tablets 3 times a day. 

After the alcohol withdrawal syndrome has been treated acutely, sedative-hypnotic medications must be tapered slowly over several weeks. Complete detoxification is not achieved with just a few days of alcohol abstinence. Several months... 

In this chapter Case studies levels 1-3 explore the management of a patient with alcoholic liver disease. The patient has alcoholic liver cirrhosis and first presents with alcohol withdrawal (Case study level 1), then the patient s risk of bleeding and treatment for the maintenance of alcohol abstinence are considered (Case study level 2). The patient then goes on to develop encephalopathy (Case study level 3). Case studies levels Ma and Mb consider two patients one presents with TB and the other liver failure.

The galactose test assesses the ability of the hepatocyte to convert galactose to glucose. A healthy liver possesses a capacity to metabolize 500-600 mg galactose per minute. Roughly 90% of parenterally administered galactose is metabolized in the liver - independently of hepatic perfusion. Galactose elimination capacity (GEC) correlates well with the viable liver cell volume (67) and is therefore referred to as a reliable measure of the metabolic function of the liver. Prior to determination of GEC, 24-hour alcohol abstinence is necessary. (50, 53, 55, 65, 67, 69, 71, 72, 75, 77, 82)... 

The frequency, localization and severity of oesophageal varices determine the life span of patients with portal hypertension. Oesophageal varices can be detected in about 80% of patients (i.e. some 20% of patients surprisingly do not present varices). In 90-95% of cases, the varices are located in the lower and central thirds of the oesophagus. The simultaneous occurrence of gastric fundic varices is only observed in 5-10% of patients. Regression of oesophageal varices (e.g. after alcohol abstinence) may occur. 

Operative lethality can be reduced to about 10% and the rate of recurrent bleeding to < 10%. With careful internal treatment, the frequency of encephalopathy can be substantially diminished to 5-10% (from the previous rate of 20-30%). The survival rate (between 2 and 10 years) is 80-40% and can be decisively influenced by the patient s lifestyle, particularly as regards alcohol abstinence. Important selective criteria include (7.) liver blood flow between 1,000 and 2,500 ml, (2.) selective portal blood flow of 15-40%, and (i.) timing of operation during the bleeding-free interval (elective) with careful pre- and aftertreatment. 

Alcohol abstinence Despite contradictory opinions, a period of alcohol abstinence should always be maintained during the acute course of disease as well as during the so-called posthepatitic vulnerable phase. Even if just a minimal amount of alcohol is actually permitted, the patient is nevertheless likely to increase consumption at will.

In various studies/clinical cases, thiamine 100 mg has been given intravenously for several days to two weeks, followed by maintenance doses of 50-100 mg orally per day until the patient is able to eat a well-balanced diet regularly (Lacasse and Lum, 2004 Chiossi et al, 2006). Long-term treatment and prevention should include continued oral thiamine supplementation, alcohol abstinence and a balanced diet (Ogershok et al, 2002), but this program is based on logic and overall good medical care, not data. 

Naltrexone 100 mg/day-I-sertraline 200 mg/day was more effective than either drug alone in depression and alcohol abstinence/ delay before relapse. Alcohol-dependent depressed patients (n = 170) were randomly assigned to four groups naltrexone only, sertraline only, naltrexone-I-sertraline, and placebo. All received weekly cognitive behavioral therapy. The rate of adverse events was lower in the combination treatment group (12%) than in the other groups (naltrexone 27%, sertraline 38%, placebo 28%) however, more subjects withdrew seven patients compared with two, four, and one in the naltrexone, sertraline, and placebo groups respectively [213. ...
