Ostre niewydolność wątroby
Objawy

Ostra niewydolność wątroby (ONW) to nagła utrata funkcji wątroby u osoby bez wcześniejszej choroby wątroby, charakteryzująca się koagulopatią (INR ≥1,5) oraz encefalopatią wątrobową. Początkowo objawy są niespecyficzne (zmęczenie, nudności, bóle brzucha), a do 50% pacjentów może być bezobjawowych. W miarę progresji pojawiają się żółtaczka, encefalopatia (klasyfikowana w 4 stopniach), wodobrzusze, obrzęki i zaburzenia krzepnięcia. Encefalopatia wątrobowa w ONW jest związana z hiperamonemią (poziom amoniaku >100 μmol/l) i obrzękiem mózgu, co zwiększa ryzyko wgłobienia i pogarsza rokowanie. ONW dzieli się na hiperaostrą (encefalopatia w ciągu 7 dni od żółtaczki), ostrą (1-4 tygodnie) i podostrą (4-12 tygodni), a szybka progresja wiąże się z gorszym rokowaniem.

Objawy ostrej niewydolności wątroby

Ostra niewydolność wątroby (ONW) to stan nagłej utraty funkcji wątroby, który występuje zazwyczaj w ciągu dni lub tygodni u osoby bez wcześniejszej choroby wątroby. Stan ten charakteryzuje się gwałtownym pogorszeniem funkcji wątroby z towarzyszącą koagulopatią (INR ≥1,5) oraz encefalopatią wątrobową12. Ostra niewydolność wątroby może rozwinąć się nagle u zdrowej osoby i stanowi stan zagrażający życiu wymagający natychmiastowej pomocy medycznej3.

Wczesne objawy niewydolności wątroby

Początkowe objawy ostrej niewydolności wątroby są często niespecyficzne i mogą przypominać objawy grypy lub innych powszechnych chorób. Te wczesne symptomy obejmują45:

Warto zauważyć, że do 50% pacjentów z ostrą chorobą wątroby może nie mieć żadnych objawów6. Jest to jeden z powodów, dla których ostra niewydolność wątroby może być trudna do rozpoznania we wczesnym stadium.

Charakterystyczne objawy rozwijającej się ostrej niewydolności wątroby

Wraz z postępem choroby, pojawiają się bardziej charakterystyczne objawy świadczące o zaawansowanej dysfunkcji wątroby78:

  • Żółtaczka – zażółcenie skóry i białkówek oczu, spowodowane nagromadzeniem bilirubiny we krwi
  • Encefalopatia wątrobowa – zaburzenia funkcji mózgu objawiające się dezorientacją, splątaniem, zmianami osobowości, drżeniami i sennością
  • Koagulopatia – zaburzenia krzepnięcia prowadzące do łatwego siniaczenia i krwawienia
  • Wodobrzusze (ascites) – gromadzenie się płynu w jamie brzusznej
  • Obrzęki – gromadzenie się płynu w kończynach, stopach, dłoniach lub twarzy
  • Odór z ust o charakterze słodkawym lub stęchłym
  • Świąd skóry
  • Ciemne zabarwienie moczu i jasne stolce

Te objawy wskazują na postępującą niewydolność wątroby, gdy toksyny, które normalnie byłyby usuwane przez wątrobę, gromadzą się we krwi9.

Progresja encefalopatii wątrobowej

Encefalopatia wątrobowa (EW) jest kluczowym objawem ostrej niewydolności wątroby i stanowi centralny element jej rozpoznania10. Jest spowodowana nagromadzeniem toksyn we krwi, które nie są prawidłowo oczyszczane przez niewydolną wątrobę, co prowadzi do zaburzeń funkcji mózgu11.

Stopnie encefalopatii wątrobowej

Encefalopatia wątrobowa w przebiegu ostrej niewydolności wątroby rozwija się zazwyczaj postępująco i może być klasyfikowana w następujących stopniach1213:

  1. Stopień I: Subtelne zmiany zachowania, skrócenie czasu skupienia uwagi, rozdrażnienie, zmiana osobowości, odwrócenie rytmu dobowego snu i czuwania
  2. Stopień II: Dezorientacja, senność, dziwne lub gwałtowne zachowania, problemy z pamięcią
  3. Stopień III: Znaczna splątanie, mowa niewyraźna lub nielogiczna, senność – pacjent śpi większość czasu, ale można go wybudzić na bodźce bólowe
  4. Stopień IV: Śpiączka, brak reakcji na bodźce bólowe

Encefalopatia wątrobowa w przebiegu ostrej niewydolności wątroby różni się od tej występującej w przewlekłej marskości tym, że często wiąże się z obrzękiem mózgu i ryzykiem wgłobienia. Jest to stan znacznie bardziej niebezpieczny14.

Mechanizm rozwoju encefalopatii

W ostrej niewydolności wątroby encefalopatia rozwija się w wyniku1516:

  • Nagromadzenia amoniaku w krwi (hiperamonemia) – poziom amoniaku powyżej 100 μmol/l przewiduje wystąpienie ciężkiej encefalopatii wątrobowej, a stężenia 150-200 μmol/l korelują z ryzykiem wgłobienia mózgu
  • Podrażnienia i obrzęku mózgu przez toksyny krążące we krwi
  • Zmian metabolicznych w mózgu wynikających z zaburzonej funkcji wątroby

Obrzęk mózgu jest głównym czynnikiem wpływającym na rokowanie i jest częstą przyczyną śmiertelności w ostrej niewydolności wątroby17.

Klasyfikacja ostrej niewydolności wątroby ze względu na szybkość progresji

Ostrą niewydolność wątroby można sklasyfikować w zależności od czasu, jaki upływa od pojawienia się żółtaczki do rozwoju encefalopatii1819:

  • Hiperaostra niewydolność wątroby: encefalopatia rozwija się w ciągu 7 dni od wystąpienia żółtaczki
  • Ostra niewydolność wątroby: encefalopatia rozwija się w ciągu 1-4 tygodni od wystąpienia żółtaczki
  • Podostra niewydolność wątroby: encefalopatia rozwija się w ciągu 4-12 tygodni od wystąpienia żółtaczki

Szybkość progresji ma znaczenie dla rokowania. Pacjenci z hiperostą i ostrą niewydolnością wątroby są bardziej narażeni na rozwój obrzęku mózgu i encefalopatii 4 stopnia20.

Powikłania ostrej niewydolności wątroby

Ostra niewydolność wątroby może prowadzić do wielu poważnych powikłań, które dodatkowo pogarszają stan pacjenta2122:

Niewydolność narządowa i zaburzenia metaboliczne

  • Niewydolność nerek – występuje u ponad 50% pacjentów z ONW, może być spowodowana ostrą martwicą kanalików nerkowych lub zespołem wątrobowo-nerkowym
  • Hipodynamiczny układ krążenia – rozszerzenie naczyń obwodowych, niskie ciśnienie systemowe, kompensacyjne zwiększenie pojemności minutowej serca
  • Hiponatremia – prawie uniwersalny objaw spowodowany retencją wody i zaburzeniem transportu sodu wewnątrzkomórkowego
  • Kwasica mleczanowa – wynikająca z upośledzenia metabolizmu mleczanów przez wątrobę
  • Hipoglikemia – spowodowana utratą zdolności wątroby do utrzymania prawidłowego poziomu glukozy we krwi

Zaburzenia krzepnięcia i ryzyko krwawienia

Wątroba ma kluczową rolę w syntezie prawie wszystkich czynników krzepnięcia oraz niektórych inhibitorów krzepnięcia i fibrynolizy. Martwica hepatocytów prowadzi do upośledzenia syntezy wielu czynników krzepnięcia i ich inhibitorów23. Powoduje to:

  • Zwiększoną skłonność do krwawień i siniaczenia
  • Krwawienia z nosa, dziąseł
  • Ryzyko krwawień z przewodu pokarmowego, w tym wymiotów krwią lub treścią przypominającą fusy kawy
  • Krwawienia wewnętrzne

Systemowy zespół zapalny i infekcje

Około 60% wszystkich pacjentów z ONW spełnia kryteria zespołu ogólnoustrojowej reakcji zapalnej, niezależnie od obecności lub braku infekcji24. Dysfunkcja immunologiczna związana z niewydolnością wątroby zwiększa podatność na infekcje bakteryjne i grzybicze, które mogą dodatkowo pogarszać rokowanie25.

Diagnostyka i rozpoznanie

Rozpoznanie ostrej niewydolności wątroby opiera się na badaniu fizykalnym, wynikach badań laboratoryjnych, wywiadzie od pacjenta oraz wywiadzie dotyczącym przeszłości medycznej w celu ustalenia zmian w stanie psychicznym, koagulopatii, szybkości wystąpienia objawów oraz braku wcześniejszej choroby wątroby26.

Kluczowymi elementami diagnostycznymi są2728:

  • Ostre podwyższenie enzymów wątrobowych – aktywność aminotransferaz często przekracza 10-krotnie górną granicę normy we wczesnej fazie choroby
  • Koagulopatia – INR ≥1,5
  • Encefalopatia wątrobowa – kluczowy objaw dla rozpoznania ONW
  • Brak wcześniejszej choroby wątroby
  • Czas trwania choroby krótszy niż 26 tygodni

Szczególne cechy progresji w grupach szczególnych

Ostra niewydolność wątroby u kobiet w ciąży

W późnej ciąży funkcja wątroby znacząco się zmniejsza, co można monitorować za pomocą badań krwi. Wczesne objawy kliniczne ONW w późnej ciąży obejmują29:

  • Hipodynamia (osłabienie)
  • Zmniejszenie apetytu
  • Ciemny bursztynowy mocz
  • Głęboka żółtaczka
  • Nudności, wymioty
  • Wzdęcie brzucha

Ostra niewydolność wątroby u dzieci

Ostra niewydolność wątroby u dzieci jest rzadka. Szansa na wyzdrowienie dziecka zależy głównie od przyczyny i wieku dziecka. Na wyniki leczenia wpływają również stadium choroby i stopień uszkodzenia mózgu30.

U dzieci objawy mogą początkowo przypominać objawy wirusowe, w tym rozstrój żołądka, uczucie stałego zmęczenia lub wymioty. Stan może szybko postępować do żółtaczki, encefalopatii i koagulopatii (problemy z krzepnięciem krwi)31.

Rokowanie i przeżywalność

Ostra niewydolność wątroby jest stanem o wysokiej śmiertelności, jednak wprowadzenie intensywnej opieki medycznej i możliwości przeszczepienia wątroby znacząco poprawiło rokowanie3233:

  • Śmiertelność przed erą przeszczepów wynosiła ponad 80%
  • Obecnie ogólna śmiertelność wynosi około 30-40%
  • Roczna przeżywalność pacjentów poddanych przeszczepowi wątroby przekracza 65%
  • Wskaźnik przeżycia bez przeszczepu wzrósł z 33% w 1998 roku do 61% w 2013 roku

Czynnikami wpływającymi na rokowanie są3435:

  • Etiologia niewydolności wątroby – pacjenci z niewydolnością spowodowaną przedawkowaniem paracetamolu mają lepsze rokowanie niż ci z postacią o niezidentyfikowanej przyczynie
  • Stopień encefalopatii – pacjenci z encefalopatią 3. lub 4. stopnia mają gorsze rokowanie
  • Rozwój powikłań, takich jak obrzęk mózgu, niewydolność nerek, zespół ostrej niewydolności oddechowej (ARDS), koagulopatia i infekcje

Wiek pacjenta również ma znaczenie – młodsi pacjenci mają generalnie lepsze rokowanie36.

Podsumowanie objawów i progresji ostrej niewydolności wątroby

Ostra niewydolność wątroby jest stanem charakteryzującym się gwałtowną utratą funkcji wątroby, która może być początkowo trudna do rozpoznania ze względu na niespecyficzne objawy. Kluczowym elementem diagnostycznym jest pojawienie się encefalopatii wątrobowej i koagulopatii3738.

Progresja objawów w ONW może przebiegać następująco3940:

  1. Okres prodromalny: zmęczenie, nudności, brak apetytu, dyskomfort w prawym górnym kwadrancie brzucha, złe samopoczucie
  2. Pojawienie się objawów żółtaczki: ciemny mocz, następnie zażółcenie oczu i skóry
  3. Objawy niewydolności wątroby: wodobrzusze, obrzęki obwodowe, koagulopatia
  4. Encefalopatia wątrobowa: od subtelnych zmian zachowania do śpiączki

Czas progresji może być różny – od dni (w przypadku hiperpostrej niewydolności wątroby) do kilku tygodni (w przypadku podostrej niewydolności wątroby)41.

Ze względu na potencjalnie śmiertelny przebieg, rozpoznanie ostrej niewydolności wątroby wymaga natychmiastowej interwencji medycznej. Pacjenci powinni być leczeni w ośrodkach, w których dostępny jest przeszczep wątroby, gdyż jest to często jedyna opcja ratująca życie4243.

  • #1 Acute liver failure – Wikipedia
    https://en.wikipedia.org/wiki/Acute_liver_failure
    The main features of acute liver failure are rapid-onset jaundice, weakness, and eventually, changes in mental status that can begin as mild confusion but progress to coma, known as hepatic encephalopathy. […] In ALF, hepatic encephalopathy leads to cerebral edema, coma, brain herniation, and eventually death. Detection of encephalopathy is central to the diagnosis of ALF. It may vary from subtle deficit in higher brain function (e.g. mood, concentration in grade I) to deep coma (grade IV). Patients presenting as acute and hyperacute liver failure are at greater risk of developing cerebral edema and grade IV encephalopathy. […] Coagulopathy is another cardinal feature of ALF. The liver has the central role in the synthesis of almost all coagulation factors and some inhibitors of coagulation and fibrinolysis. Hepatocellular necrosis leads to impaired synthesis of many coagulation factors and their inhibitors.

    Acute liver failure is defined as severe acute liver injury for fewer than twenty-six weeks duration with encephalopathy and impaired synthetic function (INR of 1.5 or higher) in a patient without cirrhosis or preexisting liver disease. […] Acute liver failure (ALF) is a rare and often heterogeneous presentation of severe liver dysfunction in a patient with otherwise no pre-existing liver disease. Though it has high morbidity and mortality, its overall survival has improved through intensive care management and emergency liver transplantation advancements. […] A high index of suspicion, early referral to a specialist liver transplantation center, and adequate supportive management remain the cornerstone for the management of ALF. […] ALF is defined as the development of severe acute liver injury with encephalopathy and impaired synthetic function (INR of 1.5 or higher) in a patient without cirrhosis or preexisting liver disease and with an illness of fewer than 26 weeks duration.

    https://www.mayoclinic.org/diseases-conditions/acute-liver-failure/symptoms-causes/syc-20352863
    Acute liver failure is loss of liver function that happens quickly in days or weeks usually in a person who has no preexisting liver disease. Acute liver failure, also known as fulminant hepatic failure, can cause serious complications, including bleeding and increased pressure in the brain. Symptoms of acute liver failure may include: Yellowing of the skin and eyeballs, called jaundice. Pain in the upper right belly area, called the abdomen. A swollen belly, known as ascites. Nausea and vomiting. A general sense of feeling unwell, known as malaise. Disorientation or confusion. Sleepiness. Breath with a musty or sweet odor. Tremors. Acute liver failure can develop quickly in an otherwise healthy person, and it is life-threatening. If you or someone you know suddenly develops a yellowing of the eyes or skin; tenderness in the upper belly; or any unusual changes in mental state, personality or behavior, seek medical attention right away. Some cases of acute liver failure have no obvious cause.
  • #4 Signs & Symptoms of Liver Failure, Causes, Treatments
    https://my.clevelandclinic.org/health/diseases/17819-liver-failure
    Acute liver failure happens suddenly, when something overwhelms your liver’s capacity to cope. Its usually a large toxic load, like poisoning. Sometimes, its a severe viral infection. In acute liver failure, your liver rapidly begins to shut down, causing immediate symptoms. This is a medical emergency. […] Symptoms of liver failure include jaundice, dark urine and itching with no rash. Symptoms of liver failure include general feelings of illness along with signs of bile building up in your body. […] You may notice different signs and symptoms of liver failure based on how advanced it is and which complications have begun to occur. The first symptoms of chronic or acute liver failure may include: Abdominal pain (especially in the upper right). Fatigue and malaise (feeling unwell). Nausea, vomiting and loss of appetite.

    https://www.webmd.com/fatty-liver-disease/digestive-diseases-liver-failure
    The early symptoms of liver failure are often similar to those of other conditions. Because of this, liver failure may be tough to diagnose at first. Early symptoms include: Nausea, Loss of appetite, Fatigue, Diarrhea. […] As liver failure progresses, the symptoms become more serious, needing care right away. These symptoms include: Jaundice (yellowing of eyes and skin), Bleeding easily, Swollen belly, Mental confusion (known as hepatic encephalopathy), Sleepiness. […] These symptoms will appear in both chronic and acute liver failure. […] The causes of acute liver failure, when the liver fails rapidly, include: Acetaminophen overdose: Large doses can damage your liver or lead to failure. […] Liver failure can be acute (sudden) or chronic (ongoing). Signs of liver failure include yellowing of the skin and eyes (jaundice), swelling of the ankles and stomach, itchy skin, constant tiredness, and loss of appetite. You can have chronic liver failure for years with no symptoms.

    https://www.hepatitis.va.gov/basics/liver-disease-symptoms.asp
    If something happens to the liver suddenly, it is acute. Some acute liver problems will cause symptoms suddenly as well. Symptoms of acute liver disease can include: […] Up to half of all people with acute liver disease have no symptoms at all. Some types of acute liver disease get better without treatment, and the liver heals itself entirely. On rare occasions an acute liver injury can require hospitalization and even liver transplant right away.
  • #7 Signs & Symptoms of Liver Failure, Causes, Treatments
    https://my.clevelandclinic.org/health/diseases/17819-liver-failure
    The first warning signs of a damaged liver that’s starting to fail are signs of bile and other toxins building up in your blood. These may include: Jaundice (yellow tint to the whites of your eyes and skin). Hepatic encephalopathy (altered mental status). Pruritus (itchy skin, but with no visible rash). Dark-colored pee (urine) and/or light-colored poop (stool). […] Other serious signs of liver failure include: Ascites (abdominal swelling with fluid). Edema (swelling with fluid in your ankles, feet, hands or face). Vomiting blood or vomit that looks like coffee grounds. Motor dysfunction (twitching, tremors or lapses in muscle control). Low urine output. Shortness of breath. […] Liver failure will cause toxins to flood your bloodstream, which feels pretty terrible. When your liver can’t filter toxins from your blood anymore, you’ll feel nauseous, tired and weak. Toxins may also infiltrate your brain, causing confusion, irritability, anxiety, drowsiness or motor dysfunction.
  • #8 Acute Liver Failure – LiverTox – NCBI Bookshelf
    https://www.ncbi.nlm.nih.gov/books/NBK548171/
    Last Update: December 11, 2019. […] Drug induced acute liver failure is defined by the appearance of signs or symptoms of hepatic failure and encephalopathy during the course of acute drug induced liver injury in a patient without previous or underlying chronic liver disease. […] Symptoms are those of severe acute liver injury, usually with a prodromal period of fatigue, nausea, poor appetite and right upper quadrant discomfort followed by dark urine and jaundice followed by signs or symptoms of hepatic failure. The diagnosis of acute liver failure is actually based upon the appearance of clinical symptoms of hepatic encephalopathy, such as mental clouding, confusion, asterixis, somnolence, stupor and coma. Other features of liver failure include abdominal swelling due to ascites, peripheral edema and coagulopathy. The rapidity of onset of the symptoms of hepatic encephalopathy varies greatly. Cases in which symptoms of encephalopathy arise within days of onset of hepatitis are usually referred to as „hyperacute”, within 5 days to 8 weeks of onset as „acute”, and after 8 weeks of onset as „subacute”. Initial symptoms of hepatic encephalopathy may be subtle and include a change in personality, forgetfulness, reversal of day-night pattern of wakefulness, and irrational or violent behavior.

    Acute liver failure is sudden damage to the liver that keeps it from working as it should and may be life-threatening. The illness may develop in days to weeks. How long it takes depends on its cause. […] A damaged liver allows toxins to build up in your blood. The toxins may cause confusion, slurred speech, and tremors. This is called hepatic encephalopathy. Your liver may also stop making blood clotting factors and certain proteins in your blood. This can lead to serious bleeding and a buildup of fluids in the belly (ascites) and legs. […] Symptoms of acute liver failure may include: Yellow colour of the skin and the white part of the eyes. (This is called jaundice). Nausea and vomiting. Pain in the upper right belly. Feeling tired. Loss of appetite. Itching. Fever. Dark-coloured stools. Fluid buildup in the belly, legs, and arms. Easy bruising. Changes in behaviour, confusion, slurred speech, and hand tremors. Symptoms can suddenly become severe and life-threatening.

    Encephalopathy can occur because the liver is unable to clear toxins from the blood properly. This can lead to irritation and swelling of the brain. If there is a decrease in your childs level of consciousness, leading to drowsiness, irritability or behaviour which is out of character, they may need to be cared for in an intensive care until. […] When the liver fails the kidneys may not work as well as they should. In this case children are given fluids via a drip and a medicine to help them pass urine. They may also need a urinary catheter to accurately measure their urine output. Some children may need help from kidney dialysis for a short time.

    Acute liver failure is a rare but often catastrophic illness affecting the liver and multiple organ systems. Patients with acute liver failure require a multidisciplinary approach for adequate management. […] The onset and duration of illness must be less than 26 weeks duration. ALF is a challenging medical emergency requiring immediate attention. Progression is associated with multiple organ failure and need for urgent liver transplant, a life-saving option for many ALF patients. […] The presenting symptoms of ALF are frequently non-specific and include fatigue, malaise, anorexia, abdominal pain, fever and jaundice. These symptoms progress in no particular order to coagulopathy preceding the development of encephalopathy, both of which are the hallmark of ALF. […] Advanced ALF often involves dysfunction of multiple organ systems. […] Cerebral edema has a major prognostic role and is a common cause of mortality in ALF. Prompt recognition and treatment is vital. […] The severity of encephalopathy (grade 3 and 4), associated with cerebral edema and coagulopathy have inverse correlation with survival.

It may vary from subtle deficit in higher brain function (e.g. mood, concentration in grade I) to deep coma (grade IV). Patients presenting as acute and hyperacute liver failure are at greater risk of developing cerebral edema and grade IV encephalopathy. […] Coagulopathy is another cardinal feature of ALF. The liver has the central role in the synthesis of almost all coagulation factors and some inhibitors of coagulation and fibrinolysis. Hepatocellular necrosis leads to impaired synthesis of many coagulation factors and their inhibitors.

    Kidney failure is common, present in more than 50% of ALF patients, either due to original insult such as paracetamol resulting in acute tubular necrosis or from hyperdynamic circulation leading to hepatorenal syndrome or functional kidney failure. […] About 60% of all ALF patients fulfil the criteria for systemic inflammatory syndrome irrespective of presence or absence of infection. […] Hyponatraemia is an almost universal finding due to water retention and a shift in intracellular sodium transport from inhibition of Na/K ATPase. […] Hyperdynamic circulation, with peripheral vasodilatation from low systemic vascular resistance, leads to hypotension. There is a compensatory increase in cardiac output. […] In late pregnancy liver function decreases significantly, which can be easily monitored by blood tests. Early clinical manifestations of ALF in late pregnancy include hypodynamia, decrease in appetite, dark amber urine, deep jaundice, nausea, vomiting, and abdominal distention.

    Acute liver failure is an uncommon condition in which rapid deterioration of liver function results in coagulopathy, usually with an international normalized ratio (INR) of greater than 1.5, and alteration in the mental status (encephalopathy) of a previously healthy individual. Acute liver failure often affects young people and carries a very high mortality. […] Signs and symptoms of acute failure may include the following: Encephalopathy, Cerebral edema: May lead to signs of increased intracranial pressure (ICP) (eg, papilledema, hypertension, bradycardia), Jaundice: Often present but not always, Ascites: Potential for hepatic vein thrombosis with rapid development in the presence of fulminant hepatic failure accompanied by abdominal pain, Right upper quadrant tenderness: Variably present, Change in liver span: May be small due to hepatic necrosis or may be enlarged due to heart failure, viral hepatitis, or Budd-Chiari syndrome, Hematemesis or melena: Due to upper gastrointestinal (GI) bleeding, Hypotension and tachycardia: Due to reduced systemic vascular resistance.

    Acute liver failure (ALF; or fulminant hepatic failure) is a loss of liver function that occurs very rapidly, usually in days or weeks, in a person with no pre-existing liver disease. […] The signs of acute liver failure usually present themselves very quickly and unexpectedly. The first symptom for many adults is an altered mental state (encephalopathy), such as sudden personality shifts or confusion. Infants and children may not experience encephalopathy or exhibit noticeable signs, but will usually have jaundice symptoms (yellowing of the skin and whites of the eyes). […] Other common symptoms: Bleeding (coagulopathy; problems with blood clotting), Extreme fatigue, Nausea or poor appetite, Abdominal discomfort, Vomiting, Fever, Enlarged liver and/or painful abdomen. […] Kidney failure is common in those with ALF, occurring more than 50% of the time. Other organs may also be affected, and bacterial and fungal infections are common. […] If you suspect that you or loved one has symptoms of acute liver failure, go to your nearest emergency room immediately.

    The diagnosis of acute liver failure requires the finding of liver test abnormalities indicative of acute liver injury, accompanied by signs or symptoms of hepatic encephalopathy in a patient with no known previous liver injury. Typical features of acute liver failure include: Acute elevations in serum enzyme elevations with serum aminotransferase levels greater than 10 times the upper limit of the normal range, early in the course of illness. […] Acute liver failure arises typically in patients with acute hepatocellular injury with an acute viral hepatitis like phenotype. Acute hepatic necrosis can also lead to acute liver failure, generally with a hyperacute presentation. Finally, sinusoidal obstruction syndrome and acute fatty liver with lactic acidosis may cause acute liver failure, but clinical features are usually quite different and different medications are typically implicated.

    In hyperacute liver failure, jaundice is usually minimal and the predominant presentation is encephalopathy, which can delay diagnosis and management. […] ALF can cause multiorgan dysfunction, which requires system-based management in a critical care unit. […] ALF diagnosis requires the presence of abnormal liver chemistries, coagulopathy (INR 1.5), and encephalopathy. […] Advances in management have improved outcomes for ALF patients, but prognosis remains poor (overall mortality of 30-40%) and is worse for ALF of indeterminate etiology.

    Acute liver failure (ALF) occurs when many cells in the liver die or become very damaged in a short amount of time. This causes the liver to fail to work as it should. […] Symptoms of acute liver failure can be like those of a virus. This can include upset stomach, feeling tired all the time, or throwing up. This can quickly progress to jaundice (yellowing of the skin), encephalopathy and coagulopathy (problem with blood clotting). […] In encephalopathy the brain does not work the way it should. This happens when the liver is not able to break down or get rid of toxic products. A liver that is working like it should is able to break down toxins and carry them out of the liver. […] Acute liver failure in children is rare. The chance the child will recover depends mainly on the cause and their age. The stage of the disease and the amount of brain damage also affect recovery. If the liver heals itself, most often there is a full recovery.

[…] Acute liver failure occurs when many cells in the liver die in a short period of time or the liver becomes damaged. Pediatric liver failure is not as common as liver failure in adults and liver failure in children is typically very rare. […] Acute liver failure can occur in children of all ages, from newborns to adolescents, and the causes vary widely. […] Children with acute liver failure may have flu-like symptoms, including fatigue, nausea, vomiting and fever. They may also show signs and symptoms resulting from liver failure, such as: Abdominal pain, Jaundice (yellow skin or eyes), Enlarged liver or spleen, Easily bleeding or bruising, Irritability or an altered mental state.

ALF is a challenging medical emergency requiring immediate attention. Progression is associated with multiple organ failure and need for urgent liver transplant, a life-saving option for many ALF patients. […] The presenting symptoms of ALF are frequently non-specific and include fatigue, malaise, anorexia, abdominal pain, fever and jaundice. These symptoms progress in no particular order to coagulopathy preceding the development of encephalopathy, both of which are the hallmark of ALF. […] Advanced ALF often involves dysfunction of multiple organ systems. […] Cerebral edema has a major prognostic role and is a common cause of mortality in ALF. Prompt recognition and treatment is vital. […] The severity of encephalopathy (grade 3 and 4), associated with cerebral edema and coagulopathy have inverse correlation with survival.

    In any case, acute liver failure must be treated quickly. Otherwise the prognosis is poor. As the liver performs a variety of tasks in our body, no human being can live without this organ. The younger an ALV patient is, the better the chances of being cured after acute liver failure. If acute liver failure occurs after chronic liver disease (acute-on-chronic), the chances of recovery are lower than in the case of acute liver failure without any previous liver damage. […] If an acute functional failure of the liver is not (or not successfully) treated, the course of this disease is usually fatal. In the advanced stage, blood pressure often drops and breathing becomes faster. As the liver can no longer adequately perform its task of detoxifying the blood, toxic substances (e.g. ammonia) enter the brain. The affected person becomes increasingly tired and eventually falls into a coma.

[…] Drug induced acute liver failure is defined by the appearance of signs or symptoms of hepatic failure and encephalopathy during the course of acute drug induced liver injury in a patient without previous or underlying chronic liver disease. […] Symptoms are those of severe acute liver injury, usually with a prodromal period of fatigue, nausea, poor appetite and right upper quadrant discomfort followed by dark urine and jaundice followed by signs or symptoms of hepatic failure. The diagnosis of acute liver failure is actually based upon the appearance of clinical symptoms of hepatic encephalopathy, such as mental clouding, confusion, asterixis, somnolence, stupor and coma. Other features of liver failure include abdominal swelling due to ascites, peripheral edema and coagulopathy. The rapidity of onset of the symptoms of hepatic encephalopathy varies greatly. Cases in which symptoms of encephalopathy arise within days of onset of hepatitis are usually referred to as „hyperacute”, within 5 days to 8 weeks of onset as „acute”, and after 8 weeks of onset as „subacute”. Initial symptoms of hepatic encephalopathy may be subtle and include a change in personality, forgetfulness, reversal of day-night pattern of wakefulness, and irrational or violent behavior.
