After binding to LPS, monocytes are activated and mature into macrophages that travel to the site of infection to secrete important cytokines for the inflammatory response. Several studies have demonstrated the dose-dependent effect that alcohol has on preventing both monocytes and macrophages from binding to the bacterial cell wall component lipopolysaccharide (LPS). “Those at increased risk should cut down or abstain from alcohol because every little thing an individual can do to improve the health and reduce risk is worth it at this point, even if the evidence is not entirely clear,” Mroszczyk-McDonald said. “Alcohol intake can kill normal healthy gut bacteria, which help to promote health and reduce risk of infection,” Mroszczyk-McDonald said. Moreover, some people shouldn’t drink at all, according to the Dietary Guidelines. This includes people who are pregnant, have alcohol abuse disorder, or are taking medications that interact with alcohol.
Finding treatment for alcohol use disorder
That may be part of the reason you’re more likely to get illnesses like liver disease, pneumonia, tuberculosis, and certain cancers. If you use alcohol, try to keep it to one drink a day for women and two drinks for men. What’s more, in a quick Google search, you can find tons of articles about alcohol worsening autoimmune symptoms and evidence to suggest moderate alcohol consumption might actually have a positive impact on autoimmune diseases like RA and Hashimoto’s. does alcohol weaken your immune system Excessive drinking can also affect your immune system’s antibodies, which are responsible for “marking” bacteria and viruses for your white blood cells to attack. Too much alcohol in your body confuses your antibodies, causing them to tell your white blood cells to attack healthy cells and make you more susceptible to illness and disease. Both the innate and the adaptive immune response are critical for effective host defense to infectious challenges.
Neuroimmune Function and the Consequences of Alcohol Exposure
Much progress has been made in elucidating the relationship between alcohol consumption and immune function and how this interaction affects human health. Normal immune function hinges on bidirectional communication of immune cells with nonimmune cells at the local level, as well as crosstalk between the brain and the periphery. These different layers of interaction make validation of the mechanisms by which alcohol affects immune function challenging.
- The immune system is typically categorized into the innate and adaptive immune response systems, both of which are essential components in the body’s defense against pathogens.
- Although this chronic weakening of lung function may not cause any immediate symptoms, these effects can manifest when a severe respiratory infection occurs.
- In other studies, chronic alcohol feeding impaired Th1 responses to a hepatitis C virus protein, a defect that was hypothesized to result from impaired secretion of IL-2 and GM–CSF by dendritic and T-cells (Geissler et al. 1997).
- It can also bind to other proteins to form adducts, such as malondialdehyde (MDA) and MDA-acetaldehyde (MAA), which play a key role in the development of liver injury and stimulate antibody responses that further promote liver inflammation and fibrosis (Tuma and Casey 2003).
Effects on B-Cells
Several lines of evidence suggest that alcohol consumption exerts a dose-dependent impact on the host response to infection. Chronic alcohol abuse leads to increased susceptibility to bacterial and viral infections, most notably a 3 to 7-fold increase in susceptibility (Schmidt and De Lint 1972) and severity (Saitz, Ghali et al. 1997) of bacterial pneumonia compared with control subjects. Similarly, the incidence of Mycobacterium tuberculosis infection among alcoholics is increased (Sabot and Vendrame 1969, Hudolin 1975, Kline, Hedemark et al. 1995, Panic and Panic 2001). Alcohol use has also been shown to drive disease progression in chronic viral infections such as human immunodeficiency virus (HIV) (Baum, Rafie et al. 2010) and Hepatitis C (Bhattacharya and Shuhart 2003). In addition, the magnitude of antibody response following vaccination with Hepatitis B is lower in alcoholics compared to controls (Nalpas, Thepot et al. 1993). In contrast, level of anti-inflammatory protein adiponectin increased (Joosten, van Erk et al. 2012).
