The onset of DTs typically happens between three to five days after stopping drinking. However, tremulousness of withdrawal convulsions (also known as rum fits) can occur during a drinking binge of shortly after stopping drinking. Alcoholic hallucinosis, on the other hand, can develop over a period of days of weeks and is characterized by auditory hallucinations. Unlike DTs, it is typically accompanied by less severe agitation and mental confusion.

Alcohol withdrawal is characterized by overactivity of the autonomic nervous system, resulting in symptoms such as agitation, tremors, sweating, nausea, vomiting, fever, and tachycardia. These symptoms typically begin 3-12 hours after drinking stops, peak between 24-48 hours, and can last up to 14 days. Withdrawal seizures may occur before blood alcohol levels reach zero, and a small percentage of people may experience delirium tremens (DT), which can be fatal if left untreated. Risk factors for DT include abnormal liver function, old age, severity of withdrawal symptoms, concurrent medical illness, heavy alcohol use, self-detox, previous history of DT, low potassium, low magnesium, and thiamine deficiency.

Pharmacologically assisted detox is often necessary for those who regularly consume more than 15 units of alcohol per day, and inpatient detox may be needed for those who regularly consume more than 30 units per day. The Clinical Institute Withdrawal Assessment of Alcohol Scale (CIWA-Ar) can be used to assess the severity of withdrawal symptoms and guide treatment decisions. Benzodiazepines are the mainstay of treatment, as chronic alcohol exposure results in decreased overall brain excitability and compensatory decrease of GABA-A neuroreceptor response to GABA. Chlordiazepoxide is a good first-line agent, while oxazepam, temazepam, and lorazepam are useful in patients with liver disease. Clomethiazole is effective but carries a high risk of respiratory depression and is not recommended. Thiamine should be offered to prevent Wernicke’s encephalopathy, and long-acting benzodiazepines can be used as prophylaxis for withdrawal seizures. Haloperidol is the treatment of choice if an antipsychotic is required.

This patient, who exhibits signs of chronic liver disease due to alcohol consumption, is at high risk of experiencing acute alcohol withdrawal, especially considering her history of delirium tremens. To prevent this, benzodiazepines are appropriate agents, with oral medications like lorazepam and diazepam being recommended. While benzodiazepines can cause hepatic encephalopathy in patients with liver cirrhosis, it is not yet known if this patient has cirrhosis, and the risk of alcohol withdrawal is significant. Therefore, she should be given benzodiazepines and closely monitored for any signs of encephalopathy. In cases of hepatic impairment, benzodiazepines with a shorter half-life, such as lorazepam and oxazepam, are preferred.

A diagnosis of alcohol use disorder only requires the presence of two or more of the 11 elements, including withdrawal and recurrent alcohol use in physically hazardous situations. Ongoing craving for alcohol does not prevent someone from being considered in sustained remission, which is defined as not meeting any criteria for alcohol use disorder for 12 months of longer, except for craving. Monitoring abstinence can be done using state markers such as GGT and CDT levels, which return to normal within days to weeks of stopping drinking, but MCV is a poor method due to the long half-life of red blood cells. Increases in GGT and CDT levels over time may indicate a return to heavy drinking.

Alcohol Dependence Syndrome: ICD-11 and DSM 5 Criteria

The criteria for diagnosing alcohol dependence syndrome in the ICD-11 and DSM 5 are quite similar, as both are based on the original concept developed by Edwards and Gross in 1976. The original concept had seven elements, including narrowing of the drinking repertoire, salience of drink seeking behavior, tolerance, withdrawal symptoms, relief of withdrawal by further drinking, compulsion to drink, and rapid reinstatement of symptoms after a period of abstinence.

The DSM-5 Alcohol Use Disorder criteria include a problematic pattern of alcohol use leading to clinically significant impairment of distress, as manifested by at least two of the following occurring within a 12-month period. These include taking alcohol in larger amounts of over a longer period than intended, persistent desire of unsuccessful efforts to cut down of control alcohol use, spending a great deal of time in activities necessary to obtain alcohol, craving of a strong desire of urge to use alcohol, recurrent alcohol use resulting in a failure to fulfill major role obligations, continued alcohol use despite having persistent or recurrent social of interpersonal problems, giving up of reducing important social, occupational, of recreational activities due to alcohol use, recurrent alcohol use in physically hazardous situations, and continued alcohol use despite knowledge of having a persistent or recurrent physical or psychological problem caused or exacerbated by alcohol. Tolerance and withdrawal symptoms are also included in the criteria.

The ICD-11 Alcohol Dependence criteria include a pattern of recurrent episodic of continuous use of alcohol with evidence of impaired regulation of alcohol use, manifested by impaired control over alcohol use, increasing precedence of alcohol use over other aspects of life, and physiological features indicative of neuroadaptation to the substance, including tolerance to the effects of alcohol of a need to use increasing amounts of alcohol to achieve the same effect, withdrawal symptoms following cessation of reduction in use of alcohol, of repeated use of alcohol of pharmacologically similar substances to prevent of alleviate withdrawal symptoms. The features of dependence are usually evident over a period of at least 12 months, but the diagnosis may be made if use is continuous for at least 3 months.

It is important to pay close attention to the question being asked. The question inquires about an item that was present in the original classification but not included in ICD-11. While salience is present in both classifications, the Edwards and Gross feature of ‘salience of drink seeking behaviour’ is equivalent to the ICD-11 feature of ‘Increasing precedence of alcohol use over other aspects of life’. The original classification included ‘rapid reinstatement of symptoms after a period of abstinence’, which is not present in ICD-11.
