Chemo Drugs and Alcohol
Alveolar macrophages in alcohol-exposed animals also exhibit decreased production of important chemokines and mediators, which impairs their ability to recruit other cell types, namely neutrophils, during times of stress and infection (Happel et al. 2004). Although the majority of data focuses on the effects of chronic alcohol ingestion, experimental evidence further suggests that even acute exposure has similar detrimental effects on alveolar macrophage immune function, although these defects readily resolve (Libon et al. 1993). Taken together, these alcohol-mediated defects in alveolar macrophage function contribute to increased vulnerability to pulmonary infections.
Bacterial pneumonia is not the only infectious disease with an increased risk among people with AUD. Lung infections with Mycobacterium tuberculosis, the underlying pathogen of TB, also occur at higher rates in this population (Jellinek 1943; World Health Organization [WHO] 2014). TB is the second-leading cause of death worldwide, accounting for 1.3 million deaths in 2012. The disease is spread from person to person through the air, when infected people cough, sneeze, speak, or sing, thereby releasing M. The infection can remain latent for years while the host’s immune system is able to combat it. Alcohol abuse is therefore a risk factor for active TB (Borgdorff et al. 1998; Buskin et al. 1994; Kline et al. 1995; Narasimhan et al. 2013).
Effects of alcohol on the lungs
In parallel to, and perhaps as a consequence of, the increased ROS production, the levels of the protective antioxidant, glutathione (GSH), are decreased by as much as 80 to 90 percent in the air sacs of the lung (i.e., alveoli). As a consequence, the expression of a protein involved in immune system regulation, transforming growth factor β (TGFβ), is increased. When activated in the alveoli (particularly during acute inflammatory stresses), TGFβ disrupts the normally tight alveolar epithelial barrier that allows the alveoli to remain air-filled.
In addition, alcohol inhibits the enzymes with which glutathione interacts to prevent cellular damage (Lieber 1993). The alcohol-induced dysregulation of lung neutrophil recruitment and clearance is only part of the problem in people with AUD, because alcohol also has harmful effects on other aspects of neutrophil functioning. However, alcohol’s effects on neutrophil phagocytosis and pathogen killing are less clear than the effects on neutrophil recruitment, and the findings to date are inconclusive.
Alcohol and the Airways
This dynamic barrier physically restricts the leakage of fluid into the alveolar space but also actively transports sodium and fluid out of the alveolar space in order to maintain this gas exchange unit. In light of the effects of alcohol on alveolar epithelial viability reported above, it is not surprising that chronic alcohol ingestion increases alveolar epithelial protein leakage and decreases the lungs’ ability to remove liquid in the rat model in vivo (Guidot et al. 2000). Again consistent with the gene expression data reported above, recent findings suggest that TGFβ1 mediates many of these effects. Chronic alcohol ingestion, via the sequential actions of angiotensin II and glutathione depletion, markedly increases the expression of TGFβ1 in the rat lung (Bechara et al. 2004, 2005). During acute inflammatory stresses such as sepsis and trauma, TGFβ1 is released and activated in the alveolar space, where it can cause the alveolar epithelial barrier dysfunction described above (Bechara et al. 2004).
- This transport is mediated by specific epithelial sodium channels located in the apical membrane and by protein pumps (i.e., Na/K-ATPase complexes) in the basolateral membrane of the epithelial cells.
- This neutrophil-recruitment process is impaired by alcohol; even brief alcohol exposure decreases neutrophil recruitment to infected sites (Astry et al. 1983).
- Two centuries later, the correlation between alcohol abuse and lung infections still remains strong.
- Regardless of the bacterial pathogen causing the infection, dysfunction of the host’s immune responses to bacterial pneumonia, particularly those involving macrophages in the lungs (i.e., alveolar macrophages) and neutrophils, is an important contributor to the pathogenesis of the disease in people with AUD.
- B cells are responsible for the second arm of the immune response (i.e., the humoral immunity) that is mediated not by specific cells but by immune molecules (i.e., antibodies) produced and secreted by B cells in response to exposure to a pathogen.
The experimental evidence that alcohol can cause a profound defect in the physical barrier of the alveolar epithelium led to the question of why alcohol abuse alone, in the absence of an acute stress such as sepsis, does not cause pulmonary edema. Additional studies revealed that alcohol causes a concurrent, and perhaps compensatory, increase in salt and water transport across the epithelium. This transport is mediated by specific famous people who died from alcoholism epithelial sodium channels located in the apical membrane and by protein pumps (i.e., Na/K-ATPase complexes) in the basolateral membrane of the epithelial cells.
Pneumoniae in vitro and a complete absence of killing of other bacterial strains in alcohol-exposed animals. In human studies, BACs as low as 0.2 percent (i.e., approximately 2.5 times the legal intoxication level) impaired neutrophil degranulation and bactericidal activity (Tamura et al. 1998). Alcohol use disorder can cause a susceptibility to infection after major trauma to the lungs / respiratory system. It creates an increased risk of aspiration of gastric acid, microbes from the upper part of the throat, decreased mucous-facilitated clearance of bacterial pathogens from the upper airway and impaired pulmonary host defenses.
If you struggle with alcohol use, or know someone that does, it can be important to recognize the warning signs of the ‘alcoholic lung.’ The most common lung conditions linked to alcohol use are detailed below. “Excessive alcohol consumption can cause nerve damage and irreversible forms of dementia,” Dr. Sengupta warns. If you drink every day, or almost every day, you might notice that you catch colds, flu or other illnesses more frequently than people who don’t drink. That’s because alcohol can weaken your immune system, slow healing and make your body more susceptible to infection.
A similar pattern of NADPH upregulation existed in human alveolar macrophages isolated from people with AUD. Restoring the duloxetine and alcohol redox balance in the lung could reverse many of these alcohol-induced defects and improve alveolar macrophage immune function (Brown et al. 2007; Yeligar et al. 2014). As noted previously, alcohol-induced oxidative stress impairs multiple critical cellular functions within the lung. In particular, the critical barrier function within the alveolar epithelium is compromised. Under normal conditions, the alveolar epithelium is a tight barrier that allows the alveoli to remain air filled despite their close proximity to the lung’s small blood vessels (i.e., capillaries), through which the entire cardiac output courses.
Thus, some studies indicate that alcohol has no effect on neutrophil phagocytosis or pathogen killing (Nilsson et al. 1996; Spagnuolo and MacGregor 1975), whereas other studies demonstrate that acute alcohol exposure impairs functional activities of neutrophils. For example, Davis and colleagues (1991) found that alcohol-fed rats failed to clear bacteria from the lungs and had increased mortality. Some of this discrepancy likely is related to differences in the bacterial pathogens studied. Thus, Jareo and colleagues (1995) noted impaired neutrophil killing of selected strains of S.
Acute Respiratory Distress Syndrome (ARDS)
These findings were the first to suggest that the nonalcohol components and additives of alcoholic beverages may be responsible for inducing asthma, rather than alcohol itself. Similar findings were seen in later studies that examined the effects of red wine in asthma (Dahl et al. 1986; Vally et al. 2000). However, researchers have not yet been able to determine conclusively if alcohol ingestion has any clinically significant effects on asthma.
2Granulocyte/macrophage colony–stimulating factor (GM-CSF) is a protein involved in the immune response. It stimulates the production of macrophages and another type of white blood cell known as granulocytes. Pneumonia is a form of acute respiratory infection that affects the lung parenchyma and oxygenation. When a patient with pneumonia is an alcoholic, the mortality rate exceeds by 50% if they are placed into intensive care (ICU). According to Kershaw, C 2008 page 1, “[a]s of 2001, pneumonia was the sixth most common cause of death in the United States”.
This cilia-desensitization effect is known as alcohol-induced cilia dysfunction (AICD). In AICD, prolonged alcohol exposure results in failure to stimulate CBF, thereby desensitizing cilia to activating agents such as beta agonists (Wyatt and Sisson 2001). AICD likely results from decreased HSP90/eNOS association, which in turn attenuates the NO-stimulated cGMP/cAMP-dependent kinase activation pathway (Simet et al. 2013a; Wyatt and Sisson 2001). Alternatively, AICD may be related to oxidant-driven eNOS uncoupling, because AICD can be prevented in alcohol-drinking mice by concurrently feeding the animals dietary antioxidants, such as Procysteine™ or N-acetylcysteine (Simet et al. 2013a). One of the most common and deadliest conditions afflicting individuals with AUD is bacterial pneumonia.
GM-CSF treatment is widely used to improve bone marrow recovery following chemotherapy for malignancies. However, the major site of eco sober house GM-CSF production actually is in the airway epithelium, where its actions are partially blocked by alcohol abuse. A clinical trial of 18 patients with septic shock demonstrated that patients who received recombinant GM-CSF treatment had less severe lung injury than those who received a placebo (Presneill et al. 2002).
