The Effects of Ethanol on the Human Organism

From WikiLectures

Czech Republic is the country with the highest beer consumption per capita.

Ethanol (ethyl alcohol, methylcarbinol, C2H5OH) is a colorless, flammable alcohol used industrially as a solvent and gasoline additive. It is the main intoxicant in most alcoholic beverages.[1]

Acute Intoxication

Alcohol intoxication refers to the spectrum of "drunkenness" and/or poisoning experienced after the ingestion of ethanol. Most of these effects are the result of CNS depression and liver metabolism, and are generally dose-dependent. While blood alcohol content (BAC) increases with the amount of ethanol consumed, other factors such as weight and speed of consumption do play a role.

Effects on the Central Nervous System

Ethanol is a CNS depressant at all doses, owing to its potentiation of the activity of GABA-A receptors and inhibition of N-methyl-D-aspartate receptors. The increased effects of GABA on the CNS is the direct causative mechanism of the typical symptoms of sedation and motor impairment associated with ethanol consumption. Inhibition of NMDA glutamate receptors impairs memory. Depression of the CNS has an overall anxiolytic effect.[2]

Ethanol intoxication can be assessed quantitatively by examining BAC. While the severity of intoxication symptoms usually correlate to blood alcohol content, it must be noted that such correlations are unpredictable in some cases including medication usage, chronic alcohol use (or dependence), and liver disease/impairment.

Acute Metabolic Effects

The primary pathway of ethanol degradation by the body takes place in the liver using the enzyme alcohol dehydrogenase (ADH, not to be confused with anti-diuretic hormone). Under the action of ADH, ethanol is converted to acetaldehyde. Acetaldehyde is highly toxic and causes cellular damage. The cellular damage caused by acetaldehyde leads to hepatocyte inflammation, as well as facial flushing and, in part, the "hangover" effect experienced after ethanol consumption.[5]

Acetaldehyde is further broken down in the liver into acetic acid by aldehyde dehydrogenase (ALDH). This acetic acid is then released into the blood and eventually becomes acetyl coenzyme A. Because these enzymes reduce NAD+, and because acetyl CoA is an intermediate of the TCA cycle and ketone body formation, the energy demands of the body (and the person's nutritional habits around the time of ethanol consumption) can contribute to several more of the acute metabolic complications of ethanol intoxication.[5]

The conversion of ethanol to acetaldehyde and then acetic acid requires reducing NAD+ to NADH. This increase in the NADH/NAD+ ratio inhibits lactate and malate dehydrogenases, thereby inhibiting gluconeogenesis. Therefore, a person who has consumed larger amounts of ethanol without adequate consumption of dietary carbohydrates is at a serious risk of acute hypoglycemic events.

The excess acetyl CoA produced as a result of ethanol breakdown is funneled away from the TCA cycle and into ketogenesis. The result of this diversion is excessive formation of ketone bodies and consequently alcoholic ketoacidosis (AKA).

Chronic Pathophysiology

According to current medical research, there is no "safe" amount of ethanol consumption.[6] Alcoholic beverages carry long-term risks to most systems of the human body.

Liver

Alcoholic liver disease progresses through these stages: steatosis, steatohepatitis, fibrosis, cirrhosis

Ethanol is associated with a myriad of hepatic pathologies, most of which are the progression stages of alcoholic liver disease (ALD): alcohol-associated steatosis, followed by steatohepatitis, hepatitis, fibrosis, and cirrhosis. It is also associated with hepatocellular carcinoma.[7]

The progression of the liver through these stages is mainly caused by the enzymatic action of ethanol metabolism and the immunogenicity of its byproducts. The acetaldehyde produced by action of ADH is highly toxic and reactive, and induces hepatocellular inflammation. It also disrupts protein, lipid, and amino acid structure and function in hepatocytes by covalently binding them. Additionally, the NADH/NAD+ ratio imbalance resulting from ADH and ALDH action furthers development of fatty liver disease by shifting hepatic metabolism towards fatty acid formation.[8]

CYP2E1 is the second major ethanol-oxidizing system in the liver. Like ADH, it catalyzes the oxidation of ethanol into acetaldehyde, but with a much slower efficiency and a much higher binding capacity. It poses its own unique dangers on hepatocytes, as it produces large quantities of reactive oxygen species (ROS) including free-radical ethanol, superoxide anions, and hydroxyl radicals. These can then react with unsaturated lipids, creating lipid peroxides that then can react with acetaldehyde and proteins. The resulting adducts (namely malondialdehyde-acetaldehyde [MAA] adducts) are bulky and immunogenic.[8]

Hepatic steatosis is the reversible condition characterized by suspended lipid droplets in the cytoplasm of hepatocytes. It usually occurs in those who consume multiple drinks daily for decades, and begins in the perivenular hepatocytes. The condition is now known to be multifactorial, as enhanced lipogenesis alone cannot entirely explain the phenomenon. Additional factors theorized to contribute to alcoholic fatty liver include diminished lipophagy, influx of fatty acids from adipose tissue, and impaired VLDL secretion.[8] Steatosis easily progresses to fibrosis due to the excess fat that is readily available for lipid peroxidation occuring in CYP2E1 ethanol metabolism.

Cirrhosis: Nodules of parenchymal liver cells engulfed by broad bands of fibrous tissue. The liver has lost its normal architecture.

Fibrosis is the transient, reversible excess accumulation of extracellular matrix protein deposits in the liver. It begins pericellularly, and is always accompanied by some degree of hepatitis. Hepatic stellate cells residing in the space of Disse activate in response to hepatic injury, transforming from a dormant lipid-storing state to one of inflammatory action. Primarily, they begin to secrete large deposits of ECM components, but they also release chemokines and pro-inflammatory cytokines to recruit leukocytes. As the leukocytes attack hepatocytes, more hepatic stellate cells are activated, and the fibrogenic response is amplified.[8] Cirrhosis is the irreversible terminal stage of fibrosis where pronounced hepatic scarring emerges.

Cirrhotic scar tissue forms "regenerative nodules of hepatic parenchyma surrounded by fibrous septa[8]" which greatly interfere with the liver's vasculature. At first, it exists in the compensated phase, then progresses into the decompensated phase. In the former, enough of the hepatic tissue is still adequately compensating for the loss of function of damaged regions. However, once the scar tissue envelops the entirety of the liver, it is referred to as the decompensated phase where portal hypertension and even liver failure develop.[8]

The most dangerous form of alcoholic liver disease, with high short-term mortality, is alcoholic hepatitis. Kupffer cells are the liver's resident macrophages and can switch between pro- and anti-inflammatory phenotypes. They are usually tolerogenic to prevent overreactions to the countless substances that pass through the liver. However, through excessive ethanol consumption along with viral, nutritional, or other predisposing factors, they can switch to the proinflammatory phenotype. Ethanol increases intestinal permeability and stimulates the overgrowth of bacteria, exposing Kupffer cells to the endotoxin of gut bacteria by endotoxemia. Exposure to endotoxin activates Kupffer cells, which then proceed to pump out pro-inflammatory cytokines (including TNFα) and ROS/RNS. Additionally, ethanol exposure sensitizes hepatocytes to TNFα, and they undergo apoptosis as a result. When distressed hepatocytes containing MMA adducts die, they release exosomes which are phagocytosed by Kupffer cells.[8] These Kupffer cells consequently switch to the pro-inflammatory phenotype, and the inflammatory cycle continues.

Neurological Effects

Wernicke Encephalopathy

Wernicke encephalopathy is an acute syndrome of cognitive disorder, ophthalmoparesis, and gait ataxia resulting from thiamine deficiency. Thiamine deficiency is rare, except amongst persons with alcohol use disorder. The mechanism of ethanol-associated thiamine deficiency is poorly understood, but is theorized to be the result of decreased intestinal absorption and cellular uptake of the vitamin potentially due to transporter inhibition.[9] The neurodegeneration in this syndrome is also attributed to the neurotoxic effects of protein adducts and ROS produced during ethanol metabolism.[5] This syndrome typically presents as follows: 

Cognitive manifestations [...] include restricted attention, impaired memory, disorientation, and diminished spontaneous speech output. Neurobehavioral symptoms may initially be erroneously ascribed to a mood disorder such as alcoholic depression [...]. Patients may report various neuro-ophthalmic concerns, including diplopia or more subtle visual symptoms. Examination often reveals horizontal nystagmus, which may accompany rotatory or vertical nystagmus, and bilateral but typically asymmetric lateral rectus palsy. Horizontal and lesser vertical gaze palsies are often present. Truncal and gait ataxia are found in most patients; symptoms may be profound and impair gait or even the ability to sit. [...] Gait ataxia of Wernicke syndrome may be masked by thiamine neuropathy. In its most pronounced form, Wernicke syndrome can produce coma without significant neuro-ophthalmic findings.[10]

Korsakoff Confabulatory Amnestic Syndrome

When Wernicke syndrome goes undiagnosed, it can progress to Korsakoff syndrome, which presents with additional features of antero- and retrograde amnesia, but without impairment of attention or abnormal extraocular movements. As the brain attempts to fill in memory gaps, it produces false and sometimes bizarre memories, a process known as confabulation. Sometimes, significant presentation of spontaneous meaningless speech and abulia can be present, and can be mistaken for affective disorders like alcoholic depression. Confabulation can resolve with treatment, but the amnesia typically persists and therefore, this syndrome is chronic.[10]

Marchiafava-Bignami Disease

Another condition associated with alcoholic thiamine deficiency is Marchiafava-Bignami disease, which is rare and mostly subacute. Corpus callosum (splenium) involvement in this syndrome gives rise to symptoms such as cortical disconnection, loss of consciousness, gait impairment, dysarthria, amnesia, and mental status alteration.[10]

Cerebellar Degeneration

Cerebellar vermis

Cerebellar degeneration is a condition of controversial etiology, with some believing that it is also the result of thiamine deficiency. It is diagnosed clinically, and exhibits poor recovery with thiamine deficiency treatment. The most notable aspect of the condition is alcoholic ataxia, which is due to multi-layer Purkyně cell loss in the superior cerebellar vermis, along with loss of cerebellar white matter.[10]

Alcoholic Neuropathy

Persons with alcohol use disorder can also experience peripheral neuropathy and dysautonomic syndromes including arrhythmias, POTS, orthostatic hypotension, erectile dysfunction, etc. The hallmark of alcoholic neuropathy is axonal degeneration, and while it is theorized to be the result of vitamin deficiency, malnutrition, and/or the toxic effects of ethanol metabolites (such as acetaldehyde) on the body, the pathophysiology of these conditions is unclear.[7][11]

Other Complications

Heavy ethanol consumption disturbs endocrine function in the whole body, and can even lead to thyroid and fertility complications. Mechanisms include metabolic byproducts and subsequent adaptations, as well as chronic inflammation of various crucial structures.[7] There is also a poorly-defined but undeniable link between chronic ethanol exposure and type 2 Diabetes Mellitus.[12] Due to the immunogenic and inflammatory nature of metabolic byproducts of ethanol oxidation, there is a risk of immune-mediated end-organ injury in virtually every body system, but notably the lungs and the brain. Sufferers of alcohol use disorders are susceptible to acute respiratory distress syndrome, alcohol-induced lung dysfunction, pancreatitis, and persistent neuroinflammation with catastrophic effects.[13] Additionally, increased gut permeability leading to endotoxemia contributes greatly to this organism-wide inflammatory state. Excessive ethanol consumption can also lead to malnutrition and simultaneous obesity, due to its effects on appetite and behavior, and the generally high caloric content of alcoholic beverages. These form the basis of the etiology of several interlinked conditions such as metabolic syndrome and various vitamin deficiency syndromes. Ethanol is associated with gastroesophageal reflux disease, myopathy, increased gout attacks, osteoporosis, and several cancers.[7]

Carcinogenesis

Ethanol is a group 1 carcinogen, as designated by the International Agency for Research on Cancer. This classification applies to cancers of the oral cavity, larynx, pharynx, esophagus, liver, colorectum, and female breast. Additionally, ethanol likely increases the risk of stomach and pancreatic cancers.[14]

Acetaldehyde & CYP2E1

Acetaldehyde may impair DNA synthesis and repair by binding to DNA and forming adducts. The adducts also negatively impair the structure and function of DNA, introducing mutations in the genetic sequence. Additionally, it can bind any of the enzymes involved in DNA modifications and repair, leading to perilous effects on oncogenes and tumor-suppressor genes.[14]

In chronic ethanol consumption, CYP2E1 expression is increased, and ROS production is therefore also increased. The resulting lipid peroxidation creates aldehydes capable of binding DNA, forming highly mutagenic adducts. ROS can also act as messengers that activate transcription factors, forcing cell proliferation, and can upregulate VEGF which stimulates angiogenesis and therefore supports metastasis.[14]

Reduced Immune Function

Perforin and granzyme A and B production necessary for NK cell action against mutated cells is disrupted by ethanol. Ethanol is also suspected to suppress T cell responses.[14]

Ethanol does not just have an immune-impairing effect in the longterm, as in individual episodes of heavy alcohol use ("binge drinking,") a unique phenomenon is observed. In these cases, anti-inflammatory cytokines are overexpressed, while pro-inflammatory cytokines are suppressed. This creates an immunocompromised state, where the body is increasingly susceptible to damage from viral infections.[14]

One-Carbon Metabolism, Folate, Retinoids

One-carbon metabolism is crucial for DNA methylation. Ethanol and its metabolic byproducts negatively impact the activity of enzymes involved in these processes (such as methionine synthase and methionine adenosyl transferase).[14] The disruption of adequate DNA methylation interferes with epigenetic patterns.

A central source of methyl groups for DNA methylation is folate. Ethanol depletes folate stores and, in many cases, contributes to a decrease in dietary intake of folate. Incorporation of subsequent corrupt nucleotides into the cell's genetic material causes considerable damage, including double-strand breaks.[14]

Retinoids regulate the growth, differentiation, and apoptosis of the cell. Ethanol inhibits vitamin A oxidation to retinoic acid, which due to the overexpression of CYP2E1 is used to produce toxic metabolites. Additionally, chronic ethanol use is known to be linked to decreased levels of retinoids in the liver — a possible risk factor for head and neck cancers.[14]

Estrogen Regulation

Despite the exact link between individual sex hormones and alcohol-associated breast cancer proving elusive to pinpoint, evidence shows that hormonal pathways do in fact play a role. Ethanol is thought to elevate estrogen levels through oxidative stress or inhibition of hormone degradation. It may also enhance estrogen receptor activity and increase blood DHEAS levels. DHEAS is converted to estrogen by the enzyme aromatase. Aromatase levels also appear to be increased in chronic ethanol exposure.[14]

Microbiome & Dysbiosis

Oral microorganisms break down ethanol into acetaldehyde using their catalase enzyme, but cannot catalyze the breakdown of acetaldehyde into acetate. This exposes the oral mucosa to excessive amounts of acetaldehyde. Additionally, the effects of endotoxemia and alcohol-induced gut bacterial overgrowth are directly inflammatory to the liver, nervous system, and lungs.[14]

Mechanisms of Addiction

The addictive quality of ethanol is linked to three main mechanisms: its immediate anxiolytic and mood-enhancing effects, its reinforcement of consumption habits via the mesolimbic reward pathway, and its creation of CNS tolerance by chronic adaptations of receptors.[2]

Dopaminergic Effects

Dopaminergic system

The mesolimbic reward pathway is the dopamine-driven circuit that is responsible for reward reinforcement. It modulates functions concerned with basic needs such as food, water, and sexual behavior. Many psychoactive substances including alcohol target this pathway, increasing the release of dopamine to create a feeling of euphoria ("reward") which reinforces the consumption behavior.[2][15]

Serotonin & Opioid System

Nucleus Accumbens is the central structure of the mesolimbic reward pathway. Initially, ethanol administration increases serotonin levels in this nucleus and once again reinforces behavior. Serotonin is also primarily a powerful mood-regulating neurotransmitter, and through negative reinforcement (e.g. anxiolysis) reward drinking alcoholic beverages. Chronically, however, ethanol creates a "hyposerotonergic state" via loss of serotonin neuronal axons and decrease in serotonin binding. This contributes to psychological dependency on ethanol to maintain "normal" function and to avoid unpleasant emotional symptoms of early ethanol withdrawal.[2][16]

Acute exposure of the CNS to ethanol reversibly reduces the affinity of delta opioid receptors, and inhibit enkephalin binding in particular. In chronic exposure, however, an increase in delta opioid receptor levels is observed. Ethanol also stimulates the release of endogenous opioids (endorphins), producing an analgesic and euphoric effect.[2][17] This is yet another example of negative reinforcement in ethanol dependency.

Chronic Adaptation & Tolerance

Regular ethanol consumers experience not just psychological dependence, but also physical addiction to the substance. Long-term exposure to ethanol creates CNS tolerance to it by both upregulating NDMA receptors and downregulating GABA receptors. The result of this is overactivation of the CNS in the absence of ethanol depression, causing long-term psychiatric disorders, and in particular, anxiety disorders. This can cause the sufferer to reach for more alcohol for its immediate anxiolytic effect, furthering the cycle of addiction. These CNS adaptations are a primary cause of withdrawal symptoms upon cessation of ethanol consumption.[2]

In persons with chronic alcohol use disorders, another aspect of tolerance arises: CYP2E1-mediated metabolic tolerance. CYP2E1 is an inducible enzyme, meaning that with chronic ethanol consumption, more of it becomes present in the liver.[8] Therefore, alcohol is broken down even more quickly in these individuals, and they must consume more ethanol to reach the same intoxicating effects.

Metabolic Pathways

Alcohol Dehydrogenase

Alcohol dehydrogenase catalyzes the breakdown of ethanol into acetaldehyde and of methanol into formaldehyde. ADH will only catalyze methanol breakdown if it has run out of ethanol to degrade. Because formaldehyde is more toxic to the human body than acetaldehyde, and because ADH has a higher affinity for ethanol than methanol, consumption of ethanol is clinically used to treat methanol poisoning. Providing ADH with ethanol would preoccupy it and prevent the formation of formaldehyde from methanol breakdown, allowing methanol to be excreted in the urine instead.[18]

Formaldehyde formed from the small amounts of methanol in commercial alcoholic beverages contributes significantly to the "hangover" effect. Some people therefore combat unpleasant symptoms experienced the morning after consuming such beverages by drinking more of them, furthering the cycle of addiction by behavioral reinforcement.

Structure formula of Disulfiram

Aldehyde Dehydrogenase

ALDH rapidly eliminates the highly reactive acetaldehyde into acetate, minimizing the toxicity and adverse effects of ethanol consumption. This reaction is the target of an alcohol use treatment drug known as disulfiram (Antabuse). Antabuse inhibits ALDH, allowing acetaldehyde to build up in the body after ethanol consumption to cause severely unpleasant hangover-like symptoms such as vomiting, hypotension, and tachycardia. The unpleasant experience disrupts the reward cycle associated with ethanol, and builds negative mental associations for the patient towards ethanol consumption.[19] While disulfiram is an effective deterrent from alcohol consumption, there is a high risk of non-compliance of the patient to the treatment plan, and supervised administration is recommended.

CYP2E1, Catalase

Reactive oxygen species (ROS) are generated during ethanol metabolism through the action of CYP2E1 and the microsomal ethanol oxidizing system (MEOS). The resulting oxidative stress contributes to liver damage and many other alcohol-associated pathologies. Notably, ROS cause injury and inflammation of the hepatocytes, as well as induction of apoptosis in affected tissues and organs. ROS-mediated inflammation of the CNS leads to neurodegeneration, linking chronic ethanol consumption to conditions like Alzheimer's.

Catalase is an enzyme that catalyzes the breakdown of hydrogen peroxide into water and oxygen. Mostly in the brain, and less so in the liver, catalase uses this oxidizing potential to convert ethanol into acetaldehyde. This locally produced acetaldehyde has numerous functions on the brain, including the motor impairment associated with ethanol intoxication.
