Beer And Tb: A Risky Mix?

Tuberculosis (TB) is an infectious disease that can be fatal if left untreated. While it is unlikely that alcohol will affect the results of a TB test, it is still advised that patients avoid drinking alcohol, especially in excess, for the two to three-day waiting period after the skin test has been administered. If a patient tests positive for TB, they are prescribed a combination of four antibiotics (Isoniazid, Rifampin, Ethambutol, and Pyrazinamide) to ensure the TB doesn't become resistant to treatment. Alcohol should not be consumed while taking these drugs, as the combination can cause serious liver damage. Globally, an estimated 10% of TB deaths are attributable to problematic alcohol use, and patients with a history of problem alcohol use require more effective TB treatment strategies.

Excessive alcohol consumption is a risk factor for TB

Alcohol use is associated with a 35% higher risk of TB compared to no alcohol use. The risk of TB increases as ethanol intake increases, with evidence of a threshold effect. Ethanol intake of more than 60 g per day was associated with a 68% higher risk of TB compared to no alcohol use.

Alcohol-related problems were associated with a more than three-fold higher risk of TB compared to no alcohol-related problems.

Alcohol consumption was estimated to have caused 1587449 incident cases of TB globally in 2014, corresponding to 22.02 cases per 100,000 people.

Alcohol consumption was also estimated to have caused 169721 TB deaths globally in 2014, corresponding to 2.35 deaths per 100,000 people.

Alcohol use, alcohol dosage, and alcohol-related problems all increase the risk of TB. Alcohol consumption is a major contributor to the TB burden of disease.

Alcohol should be avoided while taking TB medication to prevent liver damage

If a patient tests positive for active TB, a combination of four antibiotics (isoniazid, rifampin, ethambutol, and pyrazinamide) is prescribed to prevent the TB from becoming resistant to treatment. It is important to avoid consuming alcohol while taking these drugs as the combination can cause serious liver damage. Even if the results for active TB are negative, it is still recommended to avoid alcohol, as the doctor may prescribe a six-month course of antibiotics to kill the infection and prevent it from becoming active TB.

Alcohol use has been identified as a key driver of poor TB treatment response and is associated with delayed culture conversion, higher rates of treatment failure, relapse, and death. A study found that an estimated 10% of TB deaths globally are attributable to problematic alcohol use. Therefore, it is crucial for TB patients to refrain from consuming alcohol during their treatment to ensure optimal recovery and prevent potential harm to their liver.

Alcohol consumption can negatively impact TB treatment outcomes

Alcohol use can negatively impact TB treatment outcomes through several mechanisms. Firstly, heavy alcohol use can impact retention in care and is associated with missed directly observed therapy (DOT) visits, which are crucial for ensuring adherence to TB medication. Secondly, observational and animal studies suggest that biological mechanisms also contribute to the association between alcohol use and poor TB clinical outcomes. Alcohol can inhibit the immune system's ability to fight TB, leading to worse treatment outcomes. Additionally, alcohol can alter the pharmacokinetics and pharmacodynamics of TB drugs, affecting their absorption, metabolism, and effectiveness.

Therefore, it is essential for TB patients to avoid alcohol consumption during their treatment to optimize their chances of successful treatment outcomes.

TB patients who consume alcohol are more likely to miss treatment doses

Alcohol consumption is not recommended for TB patients, especially those taking antibiotics to treat the disease. An estimated 10% of TB-related deaths are attributable to problematic alcohol use.

Alcohol use, especially heavy episodic drinking, has been linked to delayed culture conversion and higher rates of treatment failure, relapse, and death. It impacts retention in care and is associated with missed treatment doses. A study showed that MDR TB patients who consumed alcohol during treatment missed an average of 18 more intensive phase doses.

Therefore, TB patients who consume alcohol are more likely to miss treatment doses, which can lead to poorer outcomes and increased risk of death. It is crucial for TB patients to adhere to their treatment regimens and avoid alcohol consumption during the course of their treatment to maximize their chances of recovery.

Alcohol use is associated with higher TB treatment failure, relapse, and death rates

Problem alcohol use can negatively impact TB treatment outcomes through both behavioral and physiological mechanisms. Behaviorally, alcohol use can lead to poor drug adherence and a higher rate of loss to follow-up. Physiologically, alcohol can impair the immune system, interfere with the absorption and metabolism of TB medications, and increase the risk of active TB.

Several studies have found a link between alcohol consumption and TB relapse. One study found that drinking alcohol significantly increased the risk of TB relapse and mortality. Another study suggested that alcohol reduces the activity of white blood cells, including macrophages, CD4+ lymphocytes, and CD8+ lymphocytes, which are important for fighting TB. Additionally, alcohol can interfere with the effectiveness of isoniazid, the primary drug used to treat TB.

To improve TB treatment outcomes and reduce transmission, it is crucial to address the impact of alcohol use on TB. This may include developing strategies to minimize alcohol use among TB patients, as well as optimizing drug dosing and treatment duration for those with comorbid problem alcohol use.
