Zapalenie wątroby toksyczne
Diagnostyka i diagnoza

Toksyczne zapalenie wątroby jest stanem zapalnym wywołanym ekspozycją na różnorodne substancje hepatotoksyczne, takie jak leki (np. paracetamol), alkohol, chemikalia przemysłowe, rozpuszczalniki organiczne, pestycydy, suplementy diety i toksyny środowiskowe. Diagnostyka opiera się na wykluczeniu innych przyczyn uszkodzenia wątroby oraz potwierdzeniu związku czasowego między ekspozycją a wzrostem enzymów wątrobowych, które muszą przekraczać co najmniej dwukrotnie górną granicę normy. Kluczowe badania laboratoryjne obejmują podwyższone poziomy aminotransferaz (ALT, AST często >400 IU/L), fosfatazy alkalicznej, GGT, bilirubiny (zwłaszcza >2x górnej granicy normy, co wskazuje na ciężkie uszkodzenie zgodnie z prawem Hy’a) oraz wydłużony czas protrombinowy (PT/INR >1,5) świadczący o ryzyku niewydolności wątroby. Diagnostyka różnicowa powinna wykluczyć wirusowe, autoimmunologiczne, metaboliczne i naczyniowe choroby wątroby, a także alkoholowe zapalenie wątroby, które charakteryzuje się zwykle niższymi wartościami AST (<500 U/L) i ALT (<300 U/L).

Definicja i przyczyny zapalenia wątroby toksycznego

Zapalenie wątroby toksyczne to stan zapalny wątroby wywołany reakcją na ekspozycję na substancje toksyczne, do których należą leki, alkohol, chemikalia lub suplementy diety. Powstaje, gdy wątroba ulega zapaleniu w wyniku bezpośredniego narażenia na toksyny lub gdy pacjent przyjmuje zbyt dużą ilość leku na receptę lub bez recepty.12

Toksyczne zapalenie wątroby może wywołać szereg substancji, w tym:12

  • Leki na receptę i bez recepty (np. paracetamol)
  • Alkohol
  • Chemikalia przemysłowe (np. czterochlorek węgla, chloroform, czterochloroetan)
  • Rozpuszczalniki organiczne
  • Pestycydy, herbicydy
  • Suplementy diety i zioła
  • Toksyny środowiskowe

Toksyczne zapalenie wątroby może pojawić się w krótkim czasie po ekspozycji na toksynę (godziny lub dni), ale w niektórych przypadkach reakcja może rozwijać się stopniowo przez tygodnie lub miesiące, zanim pojawią się pierwsze objawy.1

Podejście diagnostyczne do zapalenia wątroby toksycznego

Diagnoza toksycznego zapalenia wątroby stanowi wyzwanie kliniczne ze względu na brak specyficznych markerów oraz nakładanie się obrazu klinicznego z innymi schorzeniami wątroby. Jest to diagnoza z wykluczenia, wymagająca ustalenia związku przyczynowego między ekspozycją na czynnik toksyczny a uszkodzeniem wątroby.12

Zgodnie z kryteriami diagnostycznymi, trzy warunki muszą być spełnione dla rozpoznania toksycznego zapalenia wątroby:12

  1. Uszkodzenie wątroby nastąpiło po ekspozycji zawodowej lub środowiskowej na substancję toksyczną (konieczna jest dokładna historia zawodowa pacjenta)
  2. Enzymy wątrobowe muszą wzrosnąć co najmniej dwukrotnie powyżej górnej granicy normy
  3. Inne przyczyny choroby wątroby muszą zostać wykluczone

Wywiad i badanie fizykalne

Pierwszym krokiem w procesie diagnostycznym jest zebranie dokładnego wywiadu i przeprowadzenie badania fizykalnego:12

  • Szczegółowy wywiad dotyczący przyjmowanych leków, suplementów diety, ziół oraz alkoholu
  • Informacje dotyczące narażenia zawodowego na chemikalia przemysłowe lub toksyny środowiskowe
  • Ocena czasowego związku między ekspozycją a wystąpieniem objawów
  • Badanie fizykalne ukierunkowane na ocenę objawów uszkodzenia wątroby (żółtaczka, hepatomegalia, bolesność w prawym podżebrzu)

Ocena pacjenta powinna również obejmować zastosowanie walidowanych narzędzi przesiewowych w przypadku podejrzenia nadużywania alkoholu, takich jak kwestionariusze CAGE lub AUDIT.1

Badania laboratoryjne

Badania laboratoryjne stanowią kluczowy element diagnostyki toksycznego zapalenia wątroby:123

  • Enzymy wątrobowe: Podwyższona aktywność aminotransferaz (ALT, AST) jest głównym wskaźnikiem uszkodzenia hepatocytów. W toksycznym zapaleniu wątroby poziomy ALT i AST mogą być znacznie podwyższone, często >400 IU/L
  • Fosfataza alkaliczna (ALP): Wzrost wskazuje na uszkodzenie dróg żółciowych
  • Gamma-glutamylotransferaza (GGT): Dodatkowy wskaźnik cholestazy lub indukcji mikrosomów wątrobowych
  • Bilirubina: Podwyższony poziom bilirubiny wskazuje na zaburzenie wydzielania żółci lub znaczne uszkodzenie wątroby
  • Czas protrombinowy (PT)/INR: Ocena funkcji syntetycznej wątroby – wydłużenie PT/INR >1,5 wskazuje na ciężkie uszkodzenie wątroby i możliwą niewydolność
  • Albumina: Ocena długoterminowej funkcji syntetycznej wątroby

Wzrost stężenia bilirubiny w surowicy powyżej 2x górnej granicy normy w połączeniu z podwyższeniem aminotransferaz jest poważnym wskaźnikiem prognostycznym. Wskazuje na ciężkie uszkodzenie wątroby (Prawo Hy’a) i wiąże się ze śmiertelnością 10-15%, szczególnie jeśli nie zostanie przerwane podawanie czynnika wywołującego.1

Jako ogólną zasadę przyjmuje się, że klinicznie istotne uszkodzenie wątroby definiuje się jako wzrost ALT przekraczający 3-krotnie górną granicę normy.12

Badania obrazowe

Badania obrazowe pomagają ocenić strukturę wątroby i wykluczyć inne przyczyny uszkodzenia:123

  • Ultrasonografia jamy brzusznej: Nieinwazyjna metoda oceny struktury wątroby, umożliwiająca wykluczenie innych przyczyn zaburzeń czynności wątroby (np. choroby dróg żółciowych, guzy)
  • Tomografia komputerowa (CT): Dostarcza szczegółowych obrazów wątroby, umożliwiając wykrycie zmian strukturalnych
  • Rezonans magnetyczny (MRI): Zapewnia dokładniejszą ocenę tkanek miękkich i może być pomocny w ocenie zwłóknienia wątroby
  • Elastografia (FibroScan, elastografia rezonansu magnetycznego): Nieinwazyjna ocena stopnia zwłóknienia wątroby

Rozpoznanie toksycznego zapalenia wątroby poprawia się dzięki zastosowaniu technik obrazowania, choć w ostrym toksycznym zapaleniu wątroby badania obrazowe mogą nie wykazywać specyficznych zmian.12

Biopsja wątroby

Biopsja wątroby może być pomocna w potwierdzeniu diagnozy toksycznego zapalenia wątroby i wykluczeniu innych przyczyn:12

  • Biopsja wykonywana jest po badaniach krwi i badaniach obrazowych, gdy nadal istnieją wątpliwości co do charakteru i nasilenia problemu wątrobowego
  • Podczas biopsji pobiera się cienką igłą mały fragment tkanki z wątroby, który jest następnie badany pod mikroskopem
  • Badanie histologiczne może pomóc w ocenie rodzaju i stopnia uszkodzenia wątroby, ale zwykle nie wskazuje konkretnej etiologii toksycznej

Łagodne formy toksycznego zapalenia wątroby mogą nie powodować żadnych objawów i mogą być wykryte tylko w badaniach krwi. Próbki histologiczne pobrane od pracowników narażonych na rozpuszczalniki, którzy mieli jedynie łagodne nieprawidłowości biochemiczne, wykazały znaczące zmiany stłuszczeniowe z różnym stopniem zapalenia i zwłóknienia, co sugeruje, że zmiany miąższowe mogą być wczesną cechą uszkodzenia wątroby wywołanego rozpuszczalnikami.1

Skale oceny przyczynowo-skutkowej

Aby ułatwić diagnozę polekowego uszkodzenia wątroby i ustalić związek przyczynowy między podejrzanym lekiem a uszkodzeniem wątroby, opracowano kilka klinicznych narzędzi oceny:123

  • Skala CIOMS/RUCAM: Najbardziej powszechnie stosowana skala, obejmująca system punktowy, który klasyfikuje podejrzenie związku przyczynowego jako „pewny lub wysoce prawdopodobny” (ocena 8), „prawdopodobny” (ocena 6-8), „możliwy” (ocena 3-5), „mało prawdopodobny” (ocena 1-2) i „wykluczony” (ocena 0)
  • Kryteria Marii i Victorino: Alternatywna skala oceny związku przyczynowego

W praktyce klinicznej lekarze kładą większy nacisk na obecność lub brak podobieństwa między profilem biochemicznym pacjenta a znanym profilem biochemicznym podejrzewanej toksyczności (np. uszkodzenie cholestatyczne w przypadku amoksycyliny z kwasem klawulanowym).1

Pozytywny dechallenge, definiowany jako 50% spadek poziomu transaminaz w surowicy w ciągu 8 dni od przerwania stosowania leku, jest bardzo pomocny w przypadkach stosowania wielu leków.1

Diagnostyka różnicowa

Diagnostyka różnicowa toksycznego zapalenia wątroby obejmuje wykluczenie innych przyczyn zapalenia wątroby i zaburzeń z podobnymi objawami:123

  • Wirusowe zapalenie wątroby: HAV, HBV, HCV, HEV, EBV, CMV, HSV
  • Autoimmunologiczne zapalenie wątroby: Badanie przeciwciał przeciwjądrowych (ANA), przeciwciał przeciwko mięśniom gładkim (ASMA), przeciwciał przeciwko mikrosomom wątroby i nerek typu 1 (anty-LKM1)
  • Choroby dziedziczne: Choroba Wilsona, hemochromatoza
  • Choroby metaboliczne: Niealkoholowa stłuszczeniowa choroba wątroby (NAFLD)
  • Choroby autoimmunologiczne dróg żółciowych: Pierwotna marskość żółciowa (PBC), pierwotne stwardniające zapalenie dróg żółciowych (PSC)
  • Zaburzenia naczyniowe: Zespół Budda-Chiariego, choroba wenookluzyjną wątroby

W przypadku ostrego zapalenia wątroby wywołanego alkoholem poziom AST w surowicy prawie nigdy nie przekracza 500 U/L, a wartość ALT w surowicy prawie nigdy nie przekracza 300 U/L. Ta charakterystyka może pomóc w odróżnieniu alkoholowego zapalenia wątroby od toksycznego.1

W wywiadzie bardzo istotne jest ustalenie, czy pacjent był narażony na nielegalne narkotyki lub toksyny. Podobnie jak w przypadku uszkodzenia wątroby wywołanego lekami, nielegalne narkotyki i toksyny mogą powodować bezpośrednią hepatotoksyczność lub reakcje idiosynkratyczne.1

Przypadki specjalne w diagnostyce

Zatrucie paracetamolem

Stężenie paracetamolu w surowicy stanowi podstawę diagnozy i leczenia zatrucia paracetamolem, nawet przy braku objawów klinicznych, ponieważ objawy kliniczne pojawiają się z opóźnieniem. Nomogram Rumack-Matthew interpretuje stężenie paracetamolu (w mikrogramach na mililitr) w odniesieniu do czasu (w godzinach) po spożyciu i przewiduje możliwą hepatotoksyczność po jednorazowym, ostrym spożyciu paracetamolu.1

Fazy hepatotoksyczności paracetamolu w badaniach laboratoryjnych:1

  1. Faza 1: Około 12 godzin po ostrym spożyciu, badania czynności wątroby wykazują subkliniczny wzrost stężenia transaminaz w surowicy (ALT, AST)
  2. Faza 2: Podwyższone poziomy ALT i AST, PT i stężenie bilirubiny; mogą również wystąpić nieprawidłowości w funkcjonowaniu nerek, wskazujące na nefrotoksyczność
  3. Faza 3: Ciężka hepatotoksyczność widoczna w badaniach surowicy; martwica centrolobularna wątroby diagnozowana w biopsji wątroby

Ekspozycja zawodowa na rozpuszczalniki

W przypadku podejrzenia toksycznego zapalenia wątroby wywołanego narażeniem zawodowym, kluczowe znaczenie ma dokładna historia zawodowa. Rozpuszczalniki organiczne, takie jak N,N-dimetyloformamid (DMF) i N,N-dimetyloacetoamid (DMAc), są powszechnie używane w przemyśle tekstylnym i tworzyw sztucznych i mogą powodować toksyczne zapalenie wątroby.1

Kryteria diagnostyczne zawodowej hepatopatii toksycznej (Chiny GBZ 59-2010) wskazują DMAc jako powszechny czynnik hepatotoksyczny. W przypadku toksycznego zapalenia wątroby wywołanego narażeniem zawodowym, ważne jest, aby skupić się na przypadkach indywidualnych.1

Toksyczne zapalenie wątroby spowodowane suplementami ziołowymi

Leki komplementarne, w tym preparaty ziołowe i suplementy diety, są szeroko stosowane bez recept. W związku z tym rośnie zainteresowanie ryzykiem hepatotoksyczności związanym z tymi środkami.1

Prezentacja kliniczna choroby wątroby związanej z ziołami może być ostra/podostra lub przewlekła, ale często jest podstępna. Suplementy diety na odchudzanie zawierające Garcinia cambogia zostały powiązane z przypadkami ostrego toksycznego zapalenia wątroby.12

Kliniczna prezentacja toksycznego zapalenia wątroby jest zmienna, dlatego nie jest możliwe jednoznaczne zdiagnozowanie toksycznego zapalenia wątroby wyłącznie na podstawie historii stosowania leku. Niezbędna jest diagnostyka różnicowa toksycznego zapalenia wątroby w celu wykluczenia innych chorób wątroby i postawienia prawidłowej diagnozy.1

Ocena ciężkości i rokowanie

Po ustaleniu rozpoznania toksycznego zapalenia wątroby, należy ocenić stopień ciężkości uszkodzenia wątroby, gdyż ma to istotne znaczenie dla określenia rokowania i opcji leczenia:12

  • Obecność objawów encefalopatii (splątanie/asterixis) definiuje ostrą niewydolność wątroby i wymaga pilnego skierowania do specjalisty chorób wątroby lub centrum transplantacyjnego12
  • Pacjenci, u których rozwija się koagulopatia (przedłużony PT/INR), wymagają ścisłego monitorowania i powinni być pilnie skierowani do specjalistów chorób wątroby1
  • Czynniki złego rokowania obejmują podeszły wiek, płeć żeńską, wysoki poziom AST, przedłużającą się żółtaczkę i encefalopatię1

Rokowanie jest wysoce zmienne w zależności od prezentacji pacjenta i stadium uszkodzenia wątroby. W prospektywnym badaniu przeprowadzonym w Stanach Zjednoczonych w latach 1998-2001 ogólny wskaźnik przeżycia pacjentów (w tym tych, którzy otrzymali przeszczep wątroby) wynosił 72%. Wynik ostrej niewydolności wątroby zależy od etiologii, stopnia encefalopatii wątrobowej obecnej przy przyjęciu oraz powikłań, takich jak infekcje.1

W wielu przypadkach toksyczne zapalenie wątroby jest uleczalne. Wątroba może z czasem zastąpić uszkodzone komórki, odwracając powstałe uszkodzenia. Czas regeneracji wątroby zależy od: czasu trwania schorzenia i stopnia uszkodzenia wątroby.1

Podsumowanie podejścia diagnostycznego

Diagnostyka toksycznego zapalenia wątroby wymaga kompleksowego podejścia, obejmującego:12

  1. Dokładny wywiad: Ekspozycja na leki, suplementy, alkohol lub środowiskowe czynniki hepatotoksyczne
  2. Ocena czasu: Czas od rozpoczęcia stosowania podejrzanego czynnika do wystąpienia objawów (czas do wystąpienia [latencja])
  3. Ocena ustąpienia objawów: Czas do poprawy po odstawieniu czynnika (wyzwanie)
  4. Wzorzec kliniczny: Wzorzec uszkodzenia i fenotyp kliniczny
  5. Wykluczenie innych przyczyn: Diagnostyka różnicowa
  6. Ocena prawdopodobieństwa: Czy znany jest potencjał hepatotoksyczny podejrzanego czynnika
  7. Ponowna ekspozycja: Odpowiedź na ponowną ekspozycję (rechallenge), czy to niezamierzoną czy celową

Wczesne rozpoznanie toksycznego zapalenia wątroby ma kluczowe znaczenie dla poprawy rokowania. Szybka diagnoza i leczenie mogą zapobiec dalszemu uszkodzeniu wątroby i zwiększyć szanse na pełne wyzdrowienie.1

Badanie Znaczenie diagnostyczne Interpretacja w toksycznym zapaleniu wątroby
ALT (aminotransferaza alaninowa) Marker uszkodzenia hepatocytów Wzrost ≥3x górnej granicy normy wskazuje na istotne klinicznie uszkodzenie wątroby
AST (aminotransferaza asparaginianowa) Marker uszkodzenia hepatocytów, mniej specyficzny dla wątroby Stosunek AST/ALT >2 sugeruje alkoholowe uszkodzenie wątroby
Bilirubina całkowita Marker funkcji wydzielniczej wątroby Wzrost >2x górnej granicy normy wraz z podwyższonymi aminotransferazami wskazuje na ciężkie uszkodzenie (Prawo Hy’a)
Fosfataza alkaliczna (ALP) Marker cholestazy Podwyższona w uszkodzeniu cholestatycznym
GGT (gamma-glutamylotransferaza) Marker cholestazy i indukcji enzymów Podwyższona w uszkodzeniu cholestatycznym i alkoholowym
INR/PT (czas protrombinowy) Marker funkcji syntetycznej wątroby Podwyższony >1,5 wskazuje na ciężkie uszkodzenie i zwiększone ryzyko niewydolności
Albumina Marker długoterminowej funkcji syntetycznej Obniżona w przewlekłym uszkodzeniu wątroby
Ultrasonografia Ocena struktury wątroby Może być prawidłowa lub wykazywać niespecyficzne zmiany
Tomografia komputerowa (CT) Dokładniejsza ocena struktury wątroby Wyklucza inne przyczyny, może uwidocznić zmiany strukturalne

    Toxic hepatitis is an inflammation of your liver in reaction to certain substances to which you’re exposed. Toxic hepatitis can be caused by alcohol, chemicals, drugs or nutritional supplements. […] The symptoms of toxic hepatitis often go away when exposure to the toxin stops. But toxic hepatitis can permanently damage your liver, leading to irreversible scarring of liver tissue (cirrhosis) and in some cases to liver failure, which can be life-threatening. […] Tests and procedures used to diagnose toxic hepatitis include: Physical exam. Your doctor will likely perform a physical exam and take a medical history. Be sure to bring to your appointment all medications you’re taking, including over-the-counter drugs and herbs, in their original containers. […] Blood tests. Your doctor may order blood tests that look for high levels of certain liver enzymes. These enzyme levels can show how well your liver is functioning.
  • #1 Toxic Hepatitis | Health & Human Services
    https://hhs.iowa.gov/epi-manual-guide-surveillance-investigation-and-reporting/environmental-disease/toxic-hepatitis
    Toxic hepatitis is any acute or sub-acute necrosis of the liver or other unspecified chemical hepatitis caused by exposure to non-medicinal toxic agents other than ethyl alcohol, including, but not limited to, carbon tetrachloride, chloroform, tetrachloroethane, trichloroethylene, phosphorus, TNT, chloronapthalenes, methylenedianilines, ethylene dibromide, and organic solvents. This includes ICD-9 codes 572.2 and 573.3 or ICD-10 codes K71.0 to K71.9. […] Diagnosis of toxic hepatitis caused by chemical exposure requires a thorough assessment of the patient, including clinical signs and symptoms, laboratory testing, an exposure history, and possible liver imaging and biopsy. Some of these tests are used to rule out other types of hepatitis. […] If a person is suspected of having, or has been diagnosed with toxic hepatitis, exposure to the chemical or drug(s) identified as the possible causative agent should be immediately discontinued.
  • #1 Toxic hepatitis | ABC Medical Center
    https://centromedicoabc.com/en/padecimientos/toxic-hepatitis/
    Toxic hepatitis usually appears shortly after exposure to the toxin (hours or days), but in other cases, the reaction may gradually develop over weeks or months until the first symptoms appear. […] Once the doctor analyzes your symptoms and medical history, they will perform a physical examination and ask you if you have been taking medications, dietary supplements, or herbal remedies, or if you have been exposed to chemicals. […] They will also request imaging studies to confirm the diagnosis, such as: Blood tests, MRI, Computed tomography, Ultrasound, Elastography, Liver tissue biopsy. […] The treatment to be followed will be established once the cause of hepatitis is determined and the injury produced is known, which consists of suspending intake or exposure to the toxic substance and prescribing medications to regenerate the liver and reverse the damage. […] If there are serious symptoms, you will need to receive treatment in a hospital to eliminate the toxic substance as soon as possible. […] When there is serious irreversible damage that causes severe liver failure, the only therapeutic option will be a liver transplant.

    The clinical symptoms, signs and patterns of liver test abnormalities of drug induced liver injury can mimic virtually any form of liver disease from acute viral hepatitis to gall stone disease with biliary obstruction, acute fatty liver and even chronic hepatitis and cirrhosis. […] There are no specific findings or laboratory tests that definitely prove that a suspected drug, nutritional supplement or herbal product is the cause of the injury. Drug induced liver injury is a diagnosis of exclusion and relies upon clinical judgment and knowledge about the potential of the agent to cause liver injury versus the likelihood that other forms of liver diseases are the cause. […] In judging the likelihood of drug induced liver disease, six features are important: the onset after starting the drug: time to onset [latency], the recovery after stopping the drug: time to recovery [challenge], the clinical pattern: injury pattern and clinical phenotype [phenotype], exclusion of other causes of liver injury [differential diagnosis], whether the drug is a known cause of liver injury [likelihood], response to reexposure, whether inadvertent or intentional [rechallenge].

    Three conditions must be fulfilled for the diagnosis of professional toxic hepatitis: (1) Liver damage should take place after occupational exposure to a substance; patient occupational history and the workplace in question is necessary; (2) Liver enzymes must increase to at least double the upper limit of normal levels; and (3) Tertiary conditions, such as other causes of liver disease, must be excluded. […] Clinical presentation of occupational liver disease may be acute/subacute or chronic, but is often insidious. […] Signs and symptoms of toxic hepatitis occurring may include: jaundice, itching, and abdominal pain in the upper right portion of the abdomen, fatigue, loss of appetite, nausea and vomiting, rash, weight loss, and dark or tea-color urine. […] In acute toxic hepatitis the patients condition is similar to viral hepatitis and rapidly deteriorates, resulting in marked liver dysfunction, encephalopathy and coagulopathy.

    In making a diagnosis of toxic hepatitis, your doctor will ask about your medical history, including detailed information regarding your medications, use of herbs or other over-the-counter nutritional supplements and alcohol consumption. Your doctor also will carry out a thorough physical exam, which can be helpful in determining the presence or absence of significant chronic liver disease. […] The following tests may be performed to assess the presence and severity of liver damage: […] Liver Function Tests – These include a series of special blood tests than can help determine if the liver is functioning properly. These tests also can assist in determining the extent and type of liver damage. […] Ultrasound – An ultrasound uses high-frequency sound waves to create images of organs and systems within your body. An ultrasound may be performed to generate detailed pictures of your liver.

[…] Obtaining an accurate history of alcohol use from a patient with suspected alcoholic hepatitis may be difficult. Questioning the patient’s family in private, after receiving permission from the patient to discuss his or her care with family members, may help elicit important information about the patient’s alcohol use. It is also absolutely essential that health care providers take a careful alcohol history, supplemented by use of either the CAGE or AUDIT questionnaires to establish the likelihood of problem alcohol drinking or abuse.

    Elevated AST and ALT levels may indicate liver injury. These are the enzymes that are most commonly released into your bloodstream when your liver is stressed. […] What can a liver function test diagnose? […] Possible diagnoses may include: […] Toxic hepatitis. […] A liver function test is one of the simplest ways you and your healthcare provider can check on your liver. Whether theyre looking for liver disease or they just want to test the effects of a medication or treatment, it only takes a small sample of your blood to yield a lot of information. […] Liver function tests may not provide enough information in themselves to make a diagnosis.
  • #1 Hepatotoxicity – Wikipedia
    https://en.wikipedia.org/wiki/Hepatotoxicity
    An elevation in serum bilirubin level of more than 2 times ULN with associated transaminase rise is an ominous sign. This indicates severe hepatotoxicity and is likely to lead to mortality in 10% to 15% of patients, especially if the offending drug is not stopped (Hy’s Law). This is because it requires significant damage to the liver to impair bilirubin excretion, hence minor impairment (in the absence of biliary obstruction or Gilbert syndrome) would not lead to jaundice. Other poor predictors of outcome are old age, female sex, high AST.
  • #1 Toxic hepatitis in occupational exposure to solvents
    https://pmc.ncbi.nlm.nih.gov/articles/PMC3374978/
    As a general rule, clinically significant liver injury is often defined as ALT 3 times the upper limit of normal (ULN). […] The measurement of total bile acids in serum may be a more sensitive indicator of hepatic function and has the advantage of being organ specific. […] Evaluation of the concentration of bile acids is not widely used as a routine screening test. […] The diagnosis of cirrhosis of the liver requires a histological demonstration for the evaluation of abnormal nodules of regeneration and fibrosis.

    Computed Tomography (CT) – Your doctor also may suggest a computed tomography scan, also known as a CT scan, to obtain two-dimensional images of your liver. CT is an X-Ray technique that produces more detailed images of your internal organs than conventional X-Ray exams. This technology uses an X-Ray sensing unit, which rotates around your body, and a large computer to create cross-sectional images of the inside of your body. […] Liver Biopsy – A biopsy may be performed following blood tests and X-Rays if questions still exist about the nature and severity of your liver problem. During a biopsy, a small sample of tissue is removed from your liver using a thin needle. The tissue is prepared and stained in a laboratory for examination under a microscope.

    The diagnosis of toxic hepatitis improves with the use of imaging techniques (ultrasound, contrast enhanced ultrasonography, computed tomography, magnetic resonance imaging). […] Mild forms of toxic hepatitis may not cause any symptoms and may be detected only by blood tests. […] Histological samples obtained from workers exposed to solvents that had only mild biochemical abnormalities have shown prominent fatty change, or steatosis, with degrees of inflammation and fibrosis, which suggest that parenchymal changes may be an early feature of solvent induced liver injury. […] The evaluation of plasma enzyme showed the advantage of being in the past been well tested in clinical practice, but the main disadvantage is that the enzymes are not organ specific and this can cause occasional diagnostic problems in clinical practice.

  • #1 Hepatotoxicity – Wikipedia
    https://en.wikipedia.org/wiki/Hepatotoxicity
    This remains a challenge in clinical practice due to a lack of reliable markers. Many other conditions lead to similar clinical as well as pathological pictures. To diagnose hepatotoxicity, a causal relationship between the use of the toxin or drug and subsequent liver damage has to be established, but might be difficult, especially when idiosyncratic reaction is suspected. Simultaneous use of multiple drugs may add to the complexity. As in acetaminophen toxicity, well established, dose-dependent, pharmacological hepatotoxicity is easier to spot. Several clinical scales such as CIOMS/RUCAM scale and Maria and Victorino criteria have been proposed to establish causal relationship between offending drug and liver damage. CIOMS/RUCAM scale involves a scoring system that categorizes the suspicion into „definite or highly probable” (score 8), „probable” (score 6-8), „possible” (score 3-5), „unlikely” (score 1-2) and „excluded” (score 0). In clinical practice, physicians put more emphasis on the presence or absence of similarity between the biochemical profile of the patient and known biochemical profile of the suspected toxicity (e.g., cholestatic damage in amoxycillin-clauvonic acid).

    When a single agent is involved, the diagnosis may be relatively simple, but with multiple agents, implicating a specific agent as the cause is difficult. To facilitate the diagnosis of drug-induced hepatic injury, several clinical tools for causality assessment have been developed to assist the clinician. […] Physicians must be vigilant in identifying drug-related liver injury because early detection can decrease the severity of hepatotoxicity if the drug is discontinued. The manifestations of drug-induced hepatotoxicity are highly variable, ranging from asymptomatic elevation of liver enzymes to fulminant hepatic failure. Knowledge of the commonly implicated agents and a high index of suspicion are essential in diagnosis. […] A positive dechallenge is a 50% fall in serum transaminase levels within 8 days of stopping the drug. A positive dechallenge is very helpful in cases of use of multiple medications.
  • #1 Special Considerations in Interpreting Liver Function Tests | AAFP
    https://www.aafp.org/pubs/afp/issues/1999/0415/p2223.html/1000
    Patients with cirrhosis often have normal or only slightly elevated serum AST and ALT levels. […] Various liver diseases are associated with typical ranges of AST and ALT levels. […] The highest ALT levels, often more than 10,000 U per L, are usually found in patients with acute toxic injury subsequent to, for example, acetaminophen overdose or acute ischemic insult to the liver. […] It is especially important to remember that in patients with acute alcoholic hepatitis, the serum AST level is almost never greater than 500 U per L and the serum ALT value is almost never greater than 300 U per L. […] Patients with alcoholic hepatitis can present with jaundice, abdominal pain, fever and a minimally elevated AST value, thereby leading to a misdiagnosis of cholecystitis.

    Most exogenous chemicals are processed by the liver. Similar to drug-induced liver injury, illicit drugs and toxins can cause either direct hepatotoxicity or idiosyncratic reactions. […] Detailed history is crucial in the diagnosis. Illicit drugs are often „cut” with various chemicals. Additionally, cocaine can cause acute hepatitis and a history of recent cocaine use should always be investigated in a patient with acute hepatitis. […] There are no specific signs for illicit drugs/toxin induced liver injury. Jaundice may be present. However, it is crucial to check for signs of potential liver synthetic dysfunction such as asterixis (encephalopathy) and ecchymosis (coagulopathy).

  • #1 Acetaminophen Toxicity: Practice Essentials, Background, Pathophysiology
    https://emedicine.medscape.com/article/820200-overview
    The serum acetaminophen concentration is the basis for diagnosis and treatment. A diagnostic serum concentration is helpful, even in the absence of clinical symptoms, because clinical symptoms are delayed. The Rumack-Matthew nomogram interprets the acetaminophen concentration (in micrograms per milliliter), in relation to time (in hours) after ingestion, and predicts possible hepatotoxicity after single, acute ingestions of acetaminophen. […] Recommended serum studies are follows: Liver function tests (alanine aminotransferase [ALT], aspartate aminotransferase [AST]), bilirubin [total and fractionated], alkaline phosphatase) […] In patients with mental status changes, strongly consider serum ammonia levels and CT scanning of the brain. Laboratory findings in the phases of acetaminophen hepatotoxicity are as follows: Phase 1: Approximately 12 hours after an acute ingestion, liver function studies show a subclinical rise in serum transaminase concentrations (ALT, AST) […] Phase 2: Elevated serum ALT and AST, PT, and bilirubin concentration; renal function abnormalities may also be present and indicate nephrotoxicity […] Phase 3: Severe hepatotoxicity is evident on serum studies; hepatic centrilobular necrosis is diagnosed on liver biopsy.
