Choroba wątroby związana z alkoholem
Etiologia i przyczyny

Choroba wątroby związana z alkoholem (ARLD) obejmuje spektrum patologii od alkoholowego stłuszczenia wątroby, przez alkoholowe zapalenie wątroby, aż do marskości alkoholowej i raka wątrobowokomórkowego. Głównym czynnikiem etiologicznym jest przewlekłe, nadmierne spożycie alkoholu, z minimalną dawką ryzyka marskości wynoszącą 40 g etanolu/dzień u mężczyzn i 20 g/dzień u kobiet przez ponad 15-20 lat. Patogeneza ARLD opiera się na toksycznym działaniu etanolu i aldehydu octowego, indukcji stresu oksydacyjnego, dysfunkcji mitochondrialnej, zaburzeniach metabolizmu lipidów oraz zmianach mikrobiomu jelitowego, które prowadzą do przewlekłego stanu zapalnego i włóknienia wątroby. Czynniki genetyczne (m.in. warianty PNPLA3, TM6SF2, MBOAT7), płeć żeńska, współistniejące choroby (np. zakażenie HCV, otyłość, hemochromatoza) oraz wzorce picia (codzienne spożycie vs. binge drinking) modyfikują ryzyko i przebieg choroby.

Etiologia, przyczyny i czynniki ryzyka choroby wątroby związanej z alkoholem

Choroba wątroby związana z alkoholem (ARLD, Alcohol-Related Liver Disease) to spektrum zaburzeń wątroby spowodowanych nadmiernym spożyciem alkoholu. Nadmierne i długotrwałe spożywanie alkoholu jest główną przyczyną tego schorzenia, które stanowi jedną z najczęstszych przyczyn chorób wątroby w krajach zachodnich.12 Choroba wątroby związana z alkoholem jest obecnie jedną z głównych przyczyn zgonów w Wielkiej Brytanii, wraz z paleniem tytoniu i wysokim ciśnieniem krwi.3 W Stanach Zjednoczonych alkohol odpowiada za 80% zgonów spowodowanych toksycznym uszkodzeniem wątroby i 50% przypadków marskości wątroby.4

Mechanizm uszkodzenia wątroby przez alkohol

Wątroba jest głównym narządem odpowiedzialnym za metabolizm alkoholu, co sprawia, że jest szczególnie narażona na jego toksyczne działanie.56 Istnieją dwa główne mechanizmy, poprzez które nadużywanie alkoholu może prowadzić do ARLD: spożycie dużej ilości alkoholu w krótkim czasie (picie typu „binge drinking”), co może powodować stłuszczenie wątroby i rzadziej alkoholowe zapalenie wątroby, oraz długotrwałe spożywanie alkoholu ponad zalecane limity przez wiele lat, co może prowadzić do zapalenia wątroby i marskości – poważniejszych form ARLD.78

Na poziomie komórkowym, mechanizmy uszkodzenia wątroby przez alkohol obejmują:910

  • Bezpośrednie działanie toksyczne etanolu i jego metabolitu – aldehydu octowego1112
  • Powstawanie substancji uszkadzających komórki wątroby podczas metabolizmu alkoholu13
  • Gromadzenie się nieprawidłowych poziomów tłuszczów w wątrobie14
  • Stres oksydacyjny i produkcja reaktywnych form tlenu (ROS)15
  • Aktywację odpowiedzi immunologicznej i gromadzenie cytokin16
  • Zaburzenia metabolizmu wątrobowego17
  • Zmianę przepuszczalności jelit, zwiększającą absorpcję endotoksyn uwolnionych przez bakterie jelitowe18

Alkohol indukuje mikrosomalny system oksydacji etanolu (MEOS), zwiększając jego aktywność, co prowadzi do produkcji toksycznych metabolitów.19 Aldehyd octowy, główny metabolit etanolu, uważany jest za główny czynnik uszkadzający wątrobę, powodujący upośledzenie mitochondrialnej oksydacji kwasów tłuszczowych, tworzenie wolnych rodników tlenowych i zmniejszenie zawartości glutationu w mitochondriach.20

Ilość i czas spożycia alkoholu

Ilość i czas spożywania alkoholu są najważniejszymi czynnikami ryzyka rozwoju choroby wątroby związanej z alkoholem.2122 Istnieje wyraźna zależność między ilością i czasem spożycia alkoholu a ryzykiem rozwoju ARLD:23

  • Szacowana minimalna dzienna dawka etanolu wymagana do rozwoju marskości wynosi 40 g dla mężczyzn i 20 g dla kobiet przez okres ponad 15-20 lat24
  • Codzienne spożycie więcej niż 60 g alkoholu przez mężczyzn i 20 g alkoholu przez kobiety znacznie zwiększa ryzyko marskości2526
  • Badania wskazują, że potrzeba co najmniej 100 litrów (26,4 galona) czystego alkoholu, aby spowodować trwałe uszkodzenie wątroby, co odpowiada około 30 gramom (około 2 drinkom) dziennie przez 10 lat27
  • Spożywanie 80 gramów (nieco mniej niż 6 drinków) dziennie przez 10 lat wiąże się z niemal 100% prawdopodobieństwem uszkodzenia wątroby28

Wzorzec picia również odgrywa istotną rolę – codzienne picie, w porównaniu z piciem typu „binge drinking”, wydaje się być bardziej szkodliwe.29 Jednakże nawet ostre picie typu „binge drinking” może powodować zauważalne uszkodzenie wątroby w zaledwie siedem tygodni.30 Picie alkoholu poza posiłkami zwiększa do 3 razy ryzyko alkoholowej choroby wątroby.31

Czynniki genetyczne i indywidualne

Alkoholowa choroba wątroby często występuje rodzinnie, co sugeruje udział czynników genetycznych.32 Badania genomu (GWAS) zidentyfikowały kilka genetycznych loci ryzyka dla rozwoju ARLD, w tym:33

  • Gen PNPLA3 (Patatin-like phospholipase domain-containing-3) – główny czynnik ryzyka postępu ARLD3435
  • TM6SF2 (transmembrane 6 superfamily member 2)36
  • MBOAT7 (membrane-bound O-acyltransferase domain-containing protein 7)37

Zmiany w profilach genetycznych konkretnych enzymów kluczowych dla metabolizmu alkoholu, takich jak ADH, ALDH i CYP4502E1, mogą zwiększać ryzyko rozwoju alkoholowej choroby wątroby.38 Wpływa to na indywidualną podatność na progresję do zaawansowanego zwłóknienia/marskości wśród osób pijących duże ilości alkoholu.39

Płeć jako czynnik ryzyka

Kobiety są bardziej podatne na alkoholową chorobę wątroby niż mężczyźni, nawet po uwzględnieniu różnic w wielkości ciała.4041 Kobiety mogą rozwinąć chorobę wątroby po mniejszej ekspozycji na alkohol niż mężczyźni.4243

Badania wykazały, że:44

  • Ryzyko zgonu było znacznie wyższe u kobiet w ciągu średniego okresu 26,7 lat
  • Kobiety z MetALD (metaboliczna choroba wątroby związana z alkoholem) miały o 83% większe ryzyko zgonu niż mężczyźni z MetALD
  • Kobiety z ALD miały o 160% większe ryzyko śmiertelności niż mężczyźni z ALD

Czynniki hormonalne mogą odgrywać rolę w tej zwiększonej podatności. Badania wskazują, że ustanie funkcji jajników sprzyja dysmetabolizmowi i dyslipidemii oraz zwiększa prawdopodobieństwo MASLD (stłuszczeniowa choroba wątroby związana z dysfunkcją metaboliczną) w grupie kobiet po menopauzie około 2,4 razy.45

Współistniejące choroby i stany chorobowe

Kilka czynników współistniejących może zwiększać ryzyko rozwoju ARLD lub przyspieszać jej progresję:46

  1. Nadwaga lub otyłość – zwiększa ryzyko choroby wątroby, ponieważ tłuszcz gromadzi się w wątrobie4748
  2. Zakażenie wirusem zapalenia wątroby typu C – znacznie przyspiesza proces uszkodzenia wątroby i wiąże się z młodszym wiekiem występowania, bardziej zaawansowanym uszkodzeniem histologicznym i zmniejszoną przeżywalnością4950
  3. Przeładowanie żelazem (hemochromatoza) – nadmierne żelazo może działać synergistycznie z alkoholem, indukując stres oksydacyjny i peroksydację lipidów5152
  4. Dieta wysokotłuszczowa – zwiększa podatność na uszkodzenie wątroby przez alkohol53
  5. Wcześniej istniejące choroby wątroby – np. niealkoholowa stłuszczeniowa choroba wątroby (NAFLD)54
  6. Niedożywienie – większość pacjentów z alkoholowym zapaleniem wątroby wykazuje oznaki niedożywienia białkowo-energetycznego, co może nasilać uszkodzenie wątroby5556

Alkohol może nasilać uszkodzenie wątroby spowodowane innymi czynnikami patogenetycznymi, w tym wirusami zapalenia wątroby.57 Około 20% pacjentów z alkoholowym zapaleniem wątroby ma jednocześnie zakażenie wirusem zapalenia wątroby typu C.58

Czynniki etniczne i rasowe

Istnieją różnice etniczne i rasowe w podatności na ARLD:59

  • Wyższe wskaźniki ALD obserwuje się u Afroamerykanów i Latynosów płci męskiej w porównaniu z mężczyznami rasy kaukaskiej, co nie jest związane z różnicami w ilości spożywanego alkoholu60
  • Wyniki badań uzyskane w badaniach amerykańskich i europejskich mogą nie być istotne w populacjach chińskich, japońskich i koreańskich, które genetycznie różnią się pod względem wrażliwości na insulinę, funkcji komórek beta oraz zdolności do metabolizmu alkoholu61

Kliniczna progresja choroby wątroby związanej z alkoholem

Choroba wątroby związana z alkoholem reprezentuje spektrum zaburzeń wątroby o różnym nasileniu, od stłuszczenia wątroby, przez stłuszczeniowe zapalenie wątroby, do zapalenia, włóknienia i ostatecznie marskości z przewlekłym stanem zapalnym.62 Choroba ta może również prowadzić do raka wątrobowokomórkowego (HCC).63

Spektrum kliniczne ARLD

Choroba wątroby związana z alkoholem obejmuje trzy główne fazy, które często są uważane za odrębne, postępujące manifestacje:6465

  1. Alkoholowe stłuszczenie wątroby (fatty liver) – najwcześniejsza i najczęstsza konsekwencja nadmiernego spożycia alkoholu66
  2. Alkoholowe zapalenie wątroby (alcoholic hepatitis) – może być łagodne i odwracalne lub zagrażające życiu67
  3. Marskość alkoholowa – zaawansowana choroba wątroby charakteryzująca się rozległym włóknieniem, które zaburza normalną architekturę wątroby68

Należy zauważyć, że choć alkoholowe stłuszczenie wątroby jest zwykle pierwszym etapem, a marskość ostatnim, fazy te mogą występować jednocześnie. Ponadto, nie każda osoba nadużywająca alkoholu przechodzi przez wszystkie fazy.6970

Alkoholowe stłuszczenie wątroby

Alkoholowe stłuszczenie wątroby jest powszechne wśród osób pijących dużo alkoholu:71

  • Występuje u prawie wszystkich osób nadużywających alkoholu (90-100%)7273
  • Może wystąpić również u do 40% osób spożywających alkohol w umiarkowanych ilościach (10-80 mg/dzień)74
  • Spożycie ponad 4 jednostek alkoholu dziennie prowadzi do pewnego nagromadzenia tłuszczu w wątrobie75
  • Może wystąpić nawet po krótkim okresie intensywnego picia76

W tej fazie, nadmierne spożycie alkoholu powoduje gromadzenie się tłuszczu w komórkach wątroby, co prowadzi do ich powiększenia i zaburzenia funkcji wątroby.7778 Ten stan jest zwykle odwracalny, jeśli osoba przestanie pić alkohol.79

Alkoholowe zapalenie wątroby

Alkoholowe zapalenie wątroby charakteryzuje się stanem zapalnym lub obrzękiem wątroby w wyniku spożycia alkoholu:80

  • Około jednej trzeciej osób pijących dużo alkoholu rozwinie alkoholowe zapalenie wątroby8182
  • Zwykle rozwija się po dekadzie lub dłuższym okresie alkoholizmu, ale może również wystąpić po krótkotrwałym intensywnym piciu oraz u niektórych umiarkowanych osób pijących83
  • Może wystąpić z marskością lub bez niej84

W alkoholowym zapaleniu wątroby, komórki wątroby mogą ulec zniszczeniu.85 Stan ten może być odwracalny, jeśli osoba przestanie pić alkohol, ale ciężkie alkoholowe zapalenie wątroby jest poważną i zagrażającą życiu chorobą.86

Marskość alkoholowa

Marskość alkoholowa to najbardziej zaawansowana forma ARLD:87

  • Od 10% do 20% osób pijących dużo alkoholu rozwinie marskość8889
  • Zwykle rozwija się po 10 lub więcej latach picia9091
  • Powoduje skurczenie i stwardnienie wątroby poprzez bliznowacenie92
  • Może prowadzić do niewydolności wątroby93
  • Uszkodzenie zwykle nie jest odwracalne94

W marskości, prawidłowe komórki wątroby są zastępowane tkanką bliznowatą, co uniemożliwia wątrobie prawidłowe funkcjonowanie.95 Marskość alkoholowa charakteryzuje się małymi guzkami regeneracyjnymi (mikroguzkowa).96

Interakcje z innymi chorobami wątroby

Alkohol może nasilać inne choroby wątroby:97

  • Spożywanie alkoholu przy jednoczesnym zakażeniu wirusem zapalenia wątroby typu C zwiększa ryzyko bliznowacenia wątroby w porównaniu do osób niepijących98
  • U osoby z przewlekłą chorobą wątroby (taką jak zapalenie wątroby typu B lub C), alkohol powoduje jeszcze większe uszkodzenia niż u pacjentów bez tych chorób wątroby99
  • Dodawanie alkoholu do wątroby już obciążonej zapaleniem wątroby zwiększa ryzyko rozwoju choroby wątroby, a także raka wątroby100

Ryzyko raka wątroby

Marskość alkoholowa zwiększa ryzyko rozwoju raka wątroby:101

  • Rak wątroby rozwija się u 10-15% osób z marskością spowodowaną nadużywaniem alkoholu102
  • Współistniejące nagromadzenie żelaza lub przewlekłe zapalenie wątroby typu C zwiększa ryzyko raka wątrobowokomórkowego103
  • Otyłość i cukrzyca typu 2 stanowią potencjalne ryzyko raka wątrobowokomórkowego u osób z ALD104

Indywidualna podatność na chorobę wątroby związaną z alkoholem

Mimo wyraźnej korelacji między ilością i czasem spożycia alkoholu a progresją ARLD, tylko 10-20% osób przewlekle nadużywających alkoholu będzie rozwijać zaawansowaną ARLD.105106 To sugeruje, że inne czynniki współdziałają w rozwoju choroby.107

Zmienność indywidualna

Alkoholowa choroba wątroby nie występuje u wszystkich osób pijących dużo alkoholu.108109 Choroba najczęściej występuje u osób w wieku 40-50 lat.110111 Nadmierne spożycie alkoholu jest konieczne, ale niewystarczające do rozwoju ARLD, co wskazuje na rolę czynników modyfikujących podatność.112

Na indywidualną podatność wpływają:113114

  • Czynniki genetyczne
  • Czynniki epigenetyczne
  • Czynniki środowiskowe
  • Interakcje między tymi czynnikami

Czynniki epigenetyczne

Mechanizmy epigenetyczne mogą wpływać na progresję ARLD:115

  • Bieżący metabolizm etanolu produkuje nadmierne ROS i wyczerpuje glutation, przekierowując reakcję od produkcji metioniny i S-adenozylometioniny (SAM), która jest dominującym donorem metylowym w metylacji DNA
  • Hipometylacja DNA ułatwia proliferację hepatocytów i tumorogenezę

Te zmiany epigenetyczne mogą wyjaśniać, dlaczego niektóre osoby są bardziej podatne na rozwój ARLD niż inne, mimo podobnych wzorców spożycia alkoholu.116

Polimorfizmy genów metabolizujących alkohol

Zmienność genetyczna w enzymach metabolizujących alkohol może wpływać na podatność na ARLD:117

  • Zmiany w genach kodujących dehydrogenazę alkoholową (ADH)
  • Polimorfizmy dehydrogenazy aldehydowej (ALDH)
  • Warianty cytochromu P450 2E1 (CYP4502E1)

Te polimorfizmy mogą wpływać na szybkość metabolizmu alkoholu i produkcję toksycznych metabolitów, co z kolei wpływa na ryzyko uszkodzenia wątroby.118

Mikrobiom jelitowy

Alkohol wpływa na mikrobiom jelitowy, co może przyczyniać się do rozwoju ARLD:119

  • Etanol może zmieniać skład mikrobioty jelitowej
  • Ekspozycja na etanol prowadzi do utraty komórek nabłonkowych na szczycie kosmków jelitowych120
  • Translokacja bakterii lub produktów mikrobiologicznych z jelita do wątroby jest kluczowym czynnikiem zapalnym, który indukuje przejście od stłuszczenia alkoholowego do alkoholowego stłuszczeniowego zapalenia wątroby (ASH)121

Regulacja mikrobioty poprzez probiotyki i transplantację bakterii kałowych może być potencjalnym leczeniem ARLD.122 Badania wskazują, że dysfunkcjonalny receptor polimetryczny immunoglobuliny (plgR) w wątrobie nasila alkoholową chorobę wątroby (alkoholowe zapalenie wątroby) z powodu osłabionej obrony przeciwdrobnoustrojowej przez IgA w jelicie.123

Podsumowanie etiologii choroby wątroby związanej z alkoholem

Choroba wątroby związana z alkoholem powstaje w wyniku złożonej interakcji między nadmiernym spożyciem alkoholu a różnorodnymi czynnikami modyfikującymi podatność indywidualną. Głównym czynnikiem etiologicznym jest nadmierne spożycie alkoholu, przy czym ryzyko wzrasta wraz z ilością i czasem ekspozycji. Kobiety, osoby z predyspozycjami genetycznymi, współistniejącymi chorobami wątroby oraz otyłością są szczególnie narażone na rozwój ARLD.124125

Mechanizmy patogenetyczne obejmują bezpośrednią toksyczność etanolu i jego metabolitów, stres oksydacyjny, dysfunkcję mitochondriów, zaburzenia metabolizmu lipidów, zmiany w mikrobiomie jelitowym oraz aktywację odpowiedzi immunologicznej. Te procesy prowadzą do stopniowego uszkodzenia wątroby, począwszy od stłuszczenia, poprzez zapalenie, aż do nieodwracalnej marskości i potencjalnie raka wątrobowokomórkowego.126127

Zrozumienie złożonych mechanizmów patogenetycznych leżących u podstaw ARLD ma kluczowe znaczenie dla opracowania skutecznych strategii diagnostycznych i terapeutycznych. Wczesne rozpoznanie ARLD i całkowita abstynencja od alkoholu są niezbędne w strategii leczenia, ponieważ na wczesnym etapie nie doszło jeszcze do nieodwracalnego uszkodzenia wątroby i dekompensacji wątroby.128

    Alcohol-associated liver disease (ALD) represents one of the deadliest yet preventable consequences of excessive alcohol use. […] Daily alcohol consumption, binge drinking (BD), and heavy episodic drinking (HED) are the patterns associated with a higher risk of developing ALD. […] The escalating global burden of ALD, even exceeding what was predicted, is the result of a complex interaction between the lack of public policies that regulate alcohol consumption, low awareness of the scope of the disease, late referral to specialists, underuse of available medications, insufficient funds allocated to ALD research, and non-predictable events such as the COVID-19 pandemic, where increases of up to 477 % in online alcohol sales were registered in the United States. […] Alcohol consumption remains the leading cause of cirrhosis globally and is responsible for almost 60 % of cirrhosis burden in Europe, North America, and Latin America, while hepatitis C virus (HCV) infection remains the leading cause in Southeast Asia, Africa, and East Mediterranean regions.

    https://recovered.org/alcohol/alcohol-and-health/alcoholic-liver
    Excessive alcohol use damages the tissues of the liver, producing a range of lesions, including fat deposits (steatosis), inflammation (hepatitis), and scarring (fibrosis and cirrhosis). […] Around a third of heavy drinkers will develop alcoholic hepatitis, usually after a decade or more of alcoholism. But it can also turn up following short-term binge drinking and in some moderate drinkers. […] The liver is the primary site of ethanol metabolism and therefore sustains the most tissue damage from alcohol abuse of any place in the body. […] Alcohol likely causes liver damage by causing the accumulation of toxic acetaldehyde, a metabolite of alcohol, in the liver. […] Some groups are more likely to develop alcohol-related liver disease when they drink. […] Population-level studies have found the risk of liver disease increases markedly for men for drink more than 40g of ethanol per day and for women who consume more than 20g per day. […] Cirrhosis usually requires drinking at least 80g/per day for at least 10 years. […] In extreme cases of alcohol-related liver disease, patients may be required to go under the knife for partial or full liver transplants.

    Alcohol is directly toxic to the liver, but so are the byproducts of alcohol metabolism. […] Over years of regular and excessive drinking, sustained damage to the liver from alcohol can cause liver cancer, alcohol-associated liver disease and cirrhosis. […] Alcohol-associated liver disease is the progressive decline of liver function due to inflammation and destruction of the liver cells because of alcohol use. Alcohol-associated liver disease can lead to cirrhosis or scarring of the liver, which occurs when the liver cells are injured repeatedly and try to regenerate. […] For people with alcohol-associated liver disease and cirrhosis, it’s paramount that they do not consume any alcohol, says Dr. Boike. There is no safe amount of alcohol for them to consume.

    Alcoholism is a widespread and damaging behaviour of people throughout the world. Long-term alcohol consumption has resulted in alcoholic liver disease (ALD) being the leading cause of chronic liver disease. […] Ethanol consumption changes the functional or expression profiles of various regulatory factors, such as kinases, transcription factors, and microRNAs. Therefore, the underlying mechanisms of ALD are complex, involving inflammation, mitochondrial damage, endoplasmic reticulum stress, nitrification, and oxidative stress. […] ALD is characterized by liver injury, inflammation, fibrosis, cirrhosis, and/or cancer caused by long-term or large volumes of alcohol intake. […] Although ethanol-induced liver injury has been of great concern in recent years, the underlying mechanisms of ethanol-induced liver injury are complex and involve multiple signaling pathways.

    Alcohol-induced liver injury mainly involves structural damage to liver cells, lipid accumulation, and inflammation. […] Studies have demonstrated that transcription factors, kinases, and microRNAs (miRNAs) play critical regulatory roles in ALD. […] Several mechanisms are possibly associated with ethanol-induced liver diseases. For example, acute ethanol consumption can result in oxidative stress, nitrification stress, endoplasmic reticulum (ER) stress, inflammation, and apoptosis. […] Chronic ethanol consumption can result in dysregulated lipid metabolism, lipid accumulation, and AFL and alter the gut-liver axis by damaging the tightly connective structures of the intestinal epithelium. […] Ethanol exposure can reduce mitochondrial volume and the F0 adenosine triphosphate (ATP) synthase levels and inhibit protein synthesis.

This is a disease in which alcohol useespecially long-term, excessive alcohol consumptiondamages the liver, preventing it from functioning as it should. […] Alcohol-related liver disease refers to a spectrum of disorders, and treatments vary based on the severity of liver disease. Abstinence from alcohol is the recommended in all cases to prevent further injury and complications. […] Alcohol-related liver disease (ALD) occurs when the liver is damaged by excessive consumption of alcohol, usually over a period of several years. […] The process of metabolizing alcohol can result in the production of substances that damage liver cells. It can also lead to the production of abnormal levels of fats, which are stored in the liver. Finally, alcohol ingestion can also cause liver inflammation and fibrosis (the formation of scar tissue).

    Alcoholic liver disease (ALD), also called alcohol-related liver disease (ARLD), is a term that encompasses the liver manifestations of alcohol overconsumption, including fatty liver, alcoholic hepatitis, and chronic hepatitis with liver fibrosis or cirrhosis. It is the major cause of liver disease in Western countries, and is the leading cause of death from excessive drinking. Although steatosis (fatty liver disease) will develop in any individual who consumes a large quantity of alcoholic beverages over a long period of time, this process is transient and reversible. More than 90% of all heavy drinkers develop fatty liver whilst about 25% develop the more severe alcoholic hepatitis, and 15% liver cirrhosis. […] As of 2010, known risk factors of ALD are: […] Quantity of alcohol taken: Consumption of 6080 g per day (14 g is considered one standard drink in the US, e.g. 1+12 US fl oz or 44 mL hard liquor, 5 US fl oz or 150 mL wine, 12 US fl oz or 350 mL beer; drinking a six-pack of 5% ABV beer daily would be 84 g and just over the upper limit) for 20 years or more in men, or 20 g/day for women significantly increases the risk of hepatitis and fibrosis by 6% to 41%. […] Pattern of drinking: Drinking outside of meal times increases up to 3 times the risk of alcoholic liver disease. […] Sex: Women are twice as susceptible to alcohol-related liver disease, and may develop alcoholic liver disease with shorter durations and doses of chronic consumption. […] Ethnicity: Higher rates of alcohol-related liver disease, unrelated to differences in amounts of alcohol consumed, are seen in African-American and Hispanic males compared to Caucasian males. […] Hepatitis C infection: A concomitant hepatitis C infection significantly accelerates the process of liver injury. […] Genetic factors: Genetic factors predispose both to alcoholism and to alcoholic liver disease. […] Iron overload (hemochromatosis). […] Diet: Malnutrition, particularly vitamin A and E deficiencies, can worsen alcohol-induced liver damage by preventing regeneration of hepatocytes.

[…] Experts are unsure what exactly causes steatotic liver disease, but associated factors include obesity, diabetes, high blood pressure and high cholesterol. […] Nearly one-fifth of the whole cohort, totaling 1,971 people, had steatotic liver disease, and more than 75% of these adults had MetALD. Although all forms of steatotic liver disease were about twice as common in men than women, the data showed that risk of death was significantly higher in women over a median period of 26.7 years. For example, having MetALD increased risk of dying 83% more in women than in men, when compared with people who did not have liver disease. Even further, women with ALD had a 160% greater mortality risk than men with ALD.

The more you drink above the recommended limits, the higher your risk of developing ARLD. […] There are 2 ways alcohol misuse (drinking too much) can cause ARLD. These are: drinking a large amount of alcohol in a short amount of time (binge drinking) can cause fatty liver disease and, less commonly, alcoholic hepatitis; drinking more than the recommended limits of alcohol over many years can cause hepatitis and cirrhosis, the more serious types of ARLD. […] Evidence suggests people who regularly drink more than the recommended maximum amounts are most at risk of developing ARLD. […] As well as drinking excessive amounts of alcohol, other factors can increase your chances of developing ARLD.

    Not everyone who drinks heavily develops ALD. […] While the amount of alcohol and the length of time as a heavy drinker are the key risk factors, additional forces impact the outcome. […] Carrying extra weight increases the risk of liver disease because fat builds up in the liver. […] The fat cells secrete acids which cause a reaction that destroys healthy cells in the liver, leading to scarring. […] Add alcohol to the mix and the combined effect adds additional liver damage. […] Often people who drink heavily, eat poorly. […] The lack of nutrients contributes to liver cell damage. […] How a body metabolizes alcohol is influenced by genetics. […] If certain enzymes are missing, that can affect the risk of developing ALD. […] Rates of ALD are higher in African-American and Hispanic males than in Caucasian males. […] Women are more susceptible than men to the impact of alcohol because they become more impaired than men after drinking equal amounts. […] Adding alcohol to a liver already taxed by hepatitis increases the risk of developing liver disease, as well as liver cancer.

    Alcohol-related liver disease (ARLD) refers to liver damage caused by excess alcohol intake. […] ARLD is caused by drinking too much alcohol. The more you drink above the recommended limits, the higher your risk of developing ARLD. […] There are 2 ways alcohol misuse (drinking too much) can cause ARLD. These are: drinking a large amount of alcohol in a short amount of time (binge drinking) can cause fatty liver disease and, less commonly, alcoholic hepatitis; drinking more than the recommended limits of alcohol over many years can cause hepatitis and cirrhosis, the more serious types of ARLD. […] Evidence suggests people who regularly drink more than the recommended maximum amounts are most at risk of developing ARLD. […] As well as drinking excessive amounts of alcohol, other factors can increase your chances of developing ARLD. These include: being overweight or obese; being female women appear to be more vulnerable than men to the harmful effects of alcohol; having a pre-existing liver condition, such as hepatitis C; genetics alcohol dependence and problems processing alcohol often run in families.

    Alcoholic liver disease (ALD), also called alcohol-related liver disease (ARLD), is a term that encompasses the liver manifestations of alcohol overconsumption, including fatty liver, alcoholic hepatitis, and chronic hepatitis with liver fibrosis or cirrhosis. It is the major cause of liver disease in Western countries, and is the leading cause of death from excessive drinking. Although steatosis (fatty liver disease) will develop in any individual who consumes a large quantity of alcoholic beverages over a long period of time, this process is transient and reversible. More than 90% of all heavy drinkers develop fatty liver whilst about 25% develop the more severe alcoholic hepatitis, and 15% liver cirrhosis. […] As of 2010, known risk factors of ALD are: […] Quantity of alcohol taken: Consumption of 6080 g per day (14 g is considered one standard drink in the US, e.g. 1+12 US fl oz or 44 mL hard liquor, 5 US fl oz or 150 mL wine, 12 US fl oz or 350 mL beer; drinking a six-pack of 5% ABV beer daily would be 84 g and just over the upper limit) for 20 years or more in men, or 20 g/day for women significantly increases the risk of hepatitis and fibrosis by 6% to 41%. […] Pattern of drinking: Drinking outside of meal times increases up to 3 times the risk of alcoholic liver disease. […] Sex: Women are twice as susceptible to alcohol-related liver disease, and may develop alcoholic liver disease with shorter durations and doses of chronic consumption. […] Ethnicity: Higher rates of alcohol-related liver disease, unrelated to differences in amounts of alcohol consumed, are seen in African-American and Hispanic males compared to Caucasian males.

    Excessive iron can act synergistically with alcohol to induce oxidative stress and lipid peroxidation, increasing transferrin receptor 1 (TfR1) expression to promote intestinal iron absorption; thus, the additive effect of iron absorption and deposition could potentiate progressive liver damage. […] The genetic impact on alcohol use disorder (AUD) and ALD development was elucidated in previous studies, as individual variation exists after chronic alcohol consumption. […] Several genome-wide association studies (GWAS) have identified several genetic risk loci for ALD development, including Patatin-like phospholipase domain-containing-3 (PNPLA3) gene, which is the major risk factor for the progression of ALD, and to a lesser extent, transmembrane 6 superfamily member 2 (TM6SF2) and membrane-bound O-acyltransferase domain-containing protein 7 (MBOAT7), are the key determinants of ALD progression.

    Alcoholic hepatitis is swelling, called inflammation, of the liver caused by drinking alcohol. Drinking alcohol destroys liver cells. […] Alcoholic hepatitis is caused by damage to the liver from drinking alcohol. Just how alcohol damages the liver and why it does so only in some heavy drinkers isn’t clear. […] These factors are known to play a role in alcoholic hepatitis: The body’s way of breaking down alcohol makes highly toxic chemicals. These chemicals trigger swelling, called inflammation, that destroys liver cells. Over time, scars replace healthy liver tissue. This keeps the liver from working well. This scarring, called cirrhosis, can’t be fixed. It’s the final stage of alcoholic liver disease. […] Other factors that can be involved with alcoholic hepatitis include: Other types of liver disease. Alcoholic hepatitis can make chronic liver diseases worse. For instance, if you have hepatitis C and drink, even a little, you’re more likely to get liver scarring than if you don’t drink. Lack of nutrition. Many people who drink heavily don’t get enough nutrients because they eat poorly. And alcohol keeps the body from using nutrients as it should. Lack of nutrients can damage liver cells.

    Alcohol-associated liver disease can occur among people who drink excessively, usually over a long period of time. […] People can develop alcohol-associated liver disease even if they are not alcohol dependent. This condition can also occur if people do not become intoxicated when consuming alcohol. […] One type of liver disease caused by alcohol is alcohol-associated fatty liver. Extra fat builds up in the liver cells. Most heavy drinkers develop this condition. It usually reverses if a person stops drinking alcohol. […] Alcohol-associated hepatitis is inflammation (swelling) of the liver. Liver cells can be destroyed because of this condition. It can reverse if a person stops drinking alcohol. […] Alcohol-associated cirrhosis is the most serious type of alcohol-associated liver disease. A liver with cirrhosis has become hardened with scar tissue. This makes it harder for the liver to function. Cirrhosis may be reversible in its earliest stages, but it is generally not reversible in very advanced stages.

    Alcoholic Liver Disease is damage to the liver and loss of normal liver functions due to alcohol abuse. […] There are 3 different types of liver disease related to alcohol abuse: […] Heavy drinking causes the liver to lose its ability to break down fats, and fats builds up in the liver. This is known as Alcoholic Fatty Liver Disease or ALFD. ALFD is the earliest stage of alcohol-related liver diseases. It may be reversible with abstaining from alcohol. […] Alcoholic liver disease typically occurs after years of heavy drinking. Over time, repeated damage to the liver caused by alcohol consumption causes scarring and cirrhosis (or hardening) of the liver to occur. Cirrhosis is the final stage of alcoholic liver disease. […] Alcohol affects the liver more so than any other organ in our body because it is the primary site of alcohol metabolism. This is where our bodies break down alcohol. Chronic and excessive alcohol consumption produces a variety of changes in the liver. Steatosis or fatty deposits are the earliest changes seen in the liver as a result of heavy drinking. Steatosis can progress to steatohepatitis, which is severe inflammation and damage in the liver. This can then lead to fibrosis (or abnormally large amounts of scar tissue formed as a result of damage) and cirrhosis (or hardening) of the liver.

    So, if someone drinks too much alcohol, the liver can become damaged by substances produced during the metabolism of that alcohol, the buildup of fats in the liver, and inflammation and fibrosis. This damage impairs the livers ability to function properly, which causes various symptoms and can even be fatal. […] In general, people who drink more alcohol are at elevated risk for alcohol-related liver disease. […] Several other factors may contribute to an elevated risk for ALD, including: Female gender. Women are more susceptible to ALD than men. […] Alcohol-related hepatitis is characterized by inflammation, or swelling of the liver as a result of alcohol consumption.

    Alcoholic liver disease (ALD), also called alcohol-related liver disease (ARLD), is a term that encompasses the liver manifestations of alcohol overconsumption, including fatty liver, alcoholic hepatitis, and chronic hepatitis with liver fibrosis or cirrhosis. It is the major cause of liver disease in Western countries, and is the leading cause of death from excessive drinking. Although steatosis (fatty liver disease) will develop in any individual who consumes a large quantity of alcoholic beverages over a long period of time, this process is transient and reversible. More than 90% of all heavy drinkers develop fatty liver whilst about 25% develop the more severe alcoholic hepatitis, and 15% liver cirrhosis. […] As of 2010, known risk factors of ALD are: […] Quantity of alcohol taken: Consumption of 6080 g per day (14 g is considered one standard drink in the US, e.g. 1+12 US fl oz or 44 mL hard liquor, 5 US fl oz or 150 mL wine, 12 US fl oz or 350 mL beer; drinking a six-pack of 5% ABV beer daily would be 84 g and just over the upper limit) for 20 years or more in men, or 20 g/day for women significantly increases the risk of hepatitis and fibrosis by 6% to 41%. […] Pattern of drinking: Drinking outside of meal times increases up to 3 times the risk of alcoholic liver disease. […] Sex: Women are twice as susceptible to alcohol-related liver disease, and may develop alcoholic liver disease with shorter durations and doses of chronic consumption. […] Ethnicity: Higher rates of alcohol-related liver disease, unrelated to differences in amounts of alcohol consumed, are seen in African-American and Hispanic males compared to Caucasian males. […] Hepatitis C infection: A concomitant hepatitis C infection significantly accelerates the process of liver injury. […] Genetic factors: Genetic factors predispose both to alcoholism and to alcoholic liver disease. […] Iron overload (hemochromatosis). […] Diet: Malnutrition, particularly vitamin A and E deficiencies, can worsen alcohol-induced liver damage by preventing regeneration of hepatocytes.

    Alcoholic hepatitis is swelling, called inflammation, of the liver caused by drinking alcohol. Drinking alcohol destroys liver cells. […] Alcoholic hepatitis is caused by damage to the liver from drinking alcohol. Just how alcohol damages the liver and why it does so only in some heavy drinkers isn’t clear. […] These factors are known to play a role in alcoholic hepatitis: The body’s way of breaking down alcohol makes highly toxic chemicals. These chemicals trigger swelling, called inflammation, that destroys liver cells. Over time, scars replace healthy liver tissue. This keeps the liver from working well. This scarring, called cirrhosis, can’t be fixed. It’s the final stage of alcoholic liver disease. […] Other factors that can be involved with alcoholic hepatitis include: Other types of liver disease. Alcoholic hepatitis can make chronic liver diseases worse. For instance, if you have hepatitis C and drink, even a little, you’re more likely to get liver scarring than if you don’t drink. Lack of nutrition. Many people who drink heavily don’t get enough nutrients because they eat poorly. And alcohol keeps the body from using nutrients as it should. Lack of nutrients can damage liver cells.

    Not everyone who drinks heavily develops ALD. […] While the amount of alcohol and the length of time as a heavy drinker are the key risk factors, additional forces impact the outcome. […] Carrying extra weight increases the risk of liver disease because fat builds up in the liver. […] The fat cells secrete acids which cause a reaction that destroys healthy cells in the liver, leading to scarring. […] Add alcohol to the mix and the combined effect adds additional liver damage. […] Often people who drink heavily, eat poorly. […] The lack of nutrients contributes to liver cell damage. […] How a body metabolizes alcohol is influenced by genetics. […] If certain enzymes are missing, that can affect the risk of developing ALD. […] Rates of ALD are higher in African-American and Hispanic males than in Caucasian males.

Over time, scarring and cirrhosis can occur. Cirrhosis is the final phase of alcoholic liver disease. […] Alcoholic liver disease does not occur in all heavy drinkers. The chances of getting liver disease go up the longer you have been drinking and more alcohol you consume. You do not have to get drunk for the disease to happen. […] The disease is most common in people between 40 and 50 years of age. Men are more likely to have this problem. However, women may develop the disease after less exposure to alcohol than men. Some people may have an inherited risk for the disease.

    Unhealthy alcohol consumption, which ranges from mild to severe, can cause major health issues. Chronic and excessive alcohol consumption often results in liver damage, inflammation, liver scarring, and fat build-up. […] The chances of getting this disease are higher with people who consume too much alcohol for extended periods. This disease is common in people aged 40 to 50, and men are more prone to it. […] Multiple factors increase the risk of alcoholic liver disease. The major risk for this disease is the amount of alcohol one consumes. Obesity is also one of the factors for alcoholic liver disease. People who drink alcohol regularly and carry excess body weight are at a higher risk of alcoholic hepatitis. […] Genetic changes may also tend to affect the risk factor. For example, changes in the genetic profile of the enzymes crucial to alcohol metabolism may result in causing alcoholic liver disease. Binge drinking also results in the development of alcoholic liver disease.

    Not everyone who drinks heavily develops ALD. […] While the amount of alcohol and the length of time as a heavy drinker are the key risk factors, additional forces impact the outcome. […] Carrying extra weight increases the risk of liver disease because fat builds up in the liver. […] The fat cells secrete acids which cause a reaction that destroys healthy cells in the liver, leading to scarring. […] Add alcohol to the mix and the combined effect adds additional liver damage. […] Often people who drink heavily, eat poorly. […] The lack of nutrients contributes to liver cell damage. […] How a body metabolizes alcohol is influenced by genetics. […] If certain enzymes are missing, that can affect the risk of developing ALD. […] Rates of ALD are higher in African-American and Hispanic males than in Caucasian males. […] Women are more susceptible than men to the impact of alcohol because they become more impaired than men after drinking equal amounts. […] Adding alcohol to a liver already taxed by hepatitis increases the risk of developing liver disease, as well as liver cancer.

    Alcohol-related liver disease (ALD) refers to the liver damage occurring due to excessive alcohol consumption and involves a broad spectrum of diseases that includes liver steatosis, steatohepatitis, hepatitis, cirrhosis, and hepatocellular carcinoma (HCC). […] The progression of ALD is mainly associated with the amount and duration of alcohol usage; however, it is also influenced by genetic, epigenetic, and environmental factors. […] Although there is a clear correlation between the amount and duration of alcohol intake and ALD progression, it is postulated that other co-factors (e.g., genetic, epigenetic, and environment factors) also play a role in ALD development, as only 10-20% of individuals with chronic alcohol use will progress to advanced ALD. […] Numerous studies have revealed that alcohol consumption is correlated with iron overload and hepcidin synthesis downregulation in Kupffer cells and hepatocytes in the liver, while hepcidin was proposed as a key mediator in iron homeostasis.

    Females are more susceptible to the negative effects of alcohol, even at the same levels of alcohol intake as males, so are more likely to quickly develop fibrosis, inflammation, and liver injury as a result of alcohol. […] Having hepatitis C increases the risk, and a person who consumes alcohol regularly and has had any type of hepatitis faces a higher chance of developing liver disease. […] Genetic changes can affect the risk. If a person experiences changes in the genetic profiles of particular enzymes that are key to alcohol metabolisms, such as ADH, ALDH, and CYP4502E1, they will have a higher chance of developing alcoholic liver disease.

    Ethanol metabolism can also disrupt the phospholipid bilayer membrane structure of mitochondria, resulting in the release of a large number of oxygen free radicals, lipid peroxidation, unsaturated FA destruction, and the production of malondialdehyde (MDA) and 4-hydroxynonenal (4-HNE). […] The oxidative metabolite of ethanol, acetaldehyde, is highly toxic and can readily undergo crosslinking with DNA or protein macromolecules in mitochondria. […] Notably, some nonoxidative metabolites produced by ethanol metabolism can cause damage to the mitochondrial membrane. […] Ethanol can upregulate lipid synthase and FA transporter activity to increase lipid synthesis and downregulate lipid transporters and -oxidases to reduce lipid consumption, which eventually leads to lipid accumulation. […] Ethanol exposure results in the loss of epithelial cells at the tip of intestinal villi.

    Investigators identify a mechanism thats vital to the progression of alcohol-related hepatitis, paving the way for new treatments. […] Alcohol-related liver disease (ARLD), liver damage caused by excess alcohol consumption, is one of the worlds most common causes of morbidity and mortality. […] ARLD is especially dangerous because it is typically asymptomatic until the liver has already sustained severe damage. […] This week, however, a team of investigators from MedUni Viennas Department of Laboratory Medicine shared their research findings of a new mechanism that exacerbates ARLD. […] Overall, the results indicate that dysfunctional hepatic plgR enhances alcohol-associated liver disease (alcohol-associated hepatitis), due to the weakened antimicrobial defense by IgA in the gut. […] „Our data show that dysfunction in pIgR in the liver exacerbates alcohol-related liver disease because the antimicrobial response through IgA in the gut is impaired, Hendrikx summarized. This means that enhancing pIgR in the liver or increasing the IgA levels in the intestine could be a promising starting point for novel treatment options of alcohol-related liver disease.

[…] The liver tolerates mild alcohol consumption, but as the consumption of alcohol increases, it leads to disorders of the metabolic functioning of the liver. […] Quantity and duration of the patient’s alcohol intake are the highest risk factors for the development of liver disease. […] Women are more susceptible than men. […] Obesity and high-fat diet also increase the risk of alcoholic liver disease. […] Concurrent hepatitis C infection is associated with younger age of onset, more advanced histological damage, and decreased survival.

    Alcohol-related liver disease (ARLD) refers to liver damage caused by excess alcohol intake. […] ARLD is caused by drinking too much alcohol. The more you drink above the recommended limits, the higher your risk of developing ARLD. […] There are 2 ways alcohol misuse (drinking too much) can cause ARLD. These are: drinking a large amount of alcohol in a short amount of time (binge drinking) can cause fatty liver disease and, less commonly, alcoholic hepatitis; drinking more than the recommended limits of alcohol over many years can cause hepatitis and cirrhosis, the more serious types of ARLD. […] Evidence suggests people who regularly drink more than the recommended maximum amounts are most at risk of developing ARLD. […] As well as drinking excessive amounts of alcohol, other factors can increase your chances of developing ARLD. These include: being overweight or obese; being female women appear to be more vulnerable than men to the harmful effects of alcohol; having a pre-existing liver condition, such as hepatitis C; genetics alcohol dependence and problems processing alcohol often run in families.

    Alcoholism is a widespread and damaging behaviour of people throughout the world. Long-term alcohol consumption has resulted in alcoholic liver disease (ALD) being the leading cause of chronic liver disease. […] Ethanol consumption changes the functional or expression profiles of various regulatory factors, such as kinases, transcription factors, and microRNAs. Therefore, the underlying mechanisms of ALD are complex, involving inflammation, mitochondrial damage, endoplasmic reticulum stress, nitrification, and oxidative stress. […] ALD is characterized by liver injury, inflammation, fibrosis, cirrhosis, and/or cancer caused by long-term or large volumes of alcohol intake. […] Although ethanol-induced liver injury has been of great concern in recent years, the underlying mechanisms of ethanol-induced liver injury are complex and involve multiple signaling pathways.

    Excessive iron can act synergistically with alcohol to induce the oxidative stress and lipid peroxidation, increasing transferrin receptor 1 (TfR1) expression to promote intestinal iron absorption; thus, the additive effect of iron absorption and deposition could potentiate progressive liver damage. […] The prompt diagnosis of early ALD and complete alcohol abstinence is crucial in the ALD treatment strategy, as irreversible liver damage and hepatic decompensation have not occurred at this stage. […] Complete alcohol abstinence is the cornerstone and improves the clinical outcomes in the treatment of all ALD stages. […] The current medications for relapse prevention in ALD patients are highlighted in Table 2. Among these, only disulfiram, naltrexone, and acamprosate were both approved by the US and Europe.
