AbstractLiver injury can result from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection with more than one-third of COVID-19 patients exhibiting elevated liver enzymes. Microvesicular steatosis, inflammation, vascular congestion, and thrombosis in the liver have been described in autopsy samples from COVID-19 patients. Several factors, including direct cytopathic effect of the virus, immune-mediated collateral damage, or an exacerbation of preexisting liver disease may contribute to liver pathology in COVID-19. Due to its immunological functions, the liver is an organ likely to participate in the viral response against SARS-CoV-2 and this may predispose it to injury. A better understanding of the mechanism contributing to liver injury is needed to develop and implement early measures to prevent serious liver damage in patients suffering from COVID-19. This review summarizes current reports of SARS-CoV-2 with an emphasis on how direct infection and subsequent severe inflammatory response may contribute to liver injury in patients with and without preexisting liver disease.

Liver injury—expressed as elevated liver enzymes—is common in patients with COVID-19. Little is known about the potential mechanisms of liver damage by SARS-CoV-2. A direct cytopathic effect on hepatocytes as well as injury related to hypoxia or hepatotoxicity are being considered. The aim of the study was to compare the clinical characteristic of COVID-19 disease in patients with normal and abnormal liver enzymes activity. A group of 150 patients with COVID-19, hospitalized in our center, was analyzed. Patients with the known liver comorbidities were excluded (n = 15). Clinical features and laboratory parameters were compared between patients with normal and abnormal aminotransferase values. Liver injury expressed as any alanine aminotransferase (ALT) elevation was noted in 45.6% of patients hospitalized due to COVID-19. The frequencies of aspartate aminotransferase (AST) elevation were lower. It was noted that elevated ALT/AST unfavorably affected other parameters related to liver function such as albumin level; gamma-glutamyl transpeptidase (GGTP); and partly, ALP activity and influenced inflammation-related parameters. The most probable cause of mild hepatitis during COVID-19 was anoxia and immune-mediated damage due to the inflammatory response following SARS-CoV-2 infection. A direct cytopathic effect of SARS-CoV-2 on hepatocytes, albeit less probable, can be considered as well. The use of potentially hepatotoxic drugs may contribute to liver damage.

Many drugs are metabolised in the liver, and the duration and intensity of action of such drugs are increased in some patients with liver disease. However, many patients react normally to drugs, for although some mechanisms, such as the secretion of conjugated bilirubin into the bile, may be impaired, liver enzymes may continue to metabolise drugs normally. The function of liver microsomes is probably preserved because many drugs stimulate the synthesis of microsomal enzymes (enzyme induction), even in the failing liver,1 and thereby increase the metabolism of a variety of drugs. About 200 compounds have so far been shown to induce these enzymes.

Case History—A 22 yr old man, being treated for pulmonary tuberculosis, now presenting with confusion and jaundice. Drug-induced liver injury (DILI) is relatively uncommon but can very rarely be fatal. Almost all patterns of liver disease can be induced by drugs, and some drugs may be associated with more than one type of reaction. Some cases of DILI have a genetic component. Most cases present with jaundice and/or hepatitis....

Abstract Glycogenic hepatopathy (GH) is a very rare complication seen mostly in patients with type 1 diabetes mellitus (T1DM) in whom glycemic control has been poor for a long time. We assessed liver diseases in children and adolescents with type 1 diabetes mellitus by detection of elevated liver transaminases and confirmed by fibro scan and ultrasound. One hundred and seven children and adolescents with T1DM were subjected to detailed history, physical examination, laboratory investigation and radiological investigation. Liver transaminases, mean HbA1c and pelviabdominal ultrasound were done for all patients while fibro scan for those with elevated liver enzymes only. Patients with elevated liver enzymes were reassessed after one year. Only nine of our patients have elevated liver enzymes. HbA1c and fibro scan abnormalities (F stage) were significantly higher in patients with elevated liver enzymes. (p < 0.001) After follow up a significant decrease in liver enzymes, fibro scan abnormalities and HbA1c in the group with elevated liver enzymes initially was detected. (p < 0.001) We concluded that liver disease is not a common complication in patients with long standing uncontrolled diabetes which can be reversed after proper control.

Disulfiram is a drug used to treat alcohol dependence since many years. It interferes with the metabolism of alcohol, may be associated with neurological and dermatological symptoms, and can be hepatotoxic. Due to the frequent coexistent liver test alterations due to alcohol, the true incidence of disulfiram-associated liver injury is unclear and severity of injury may vary from mildly elevated liver enzymes to fulminant hepatitis leading to death. There are several reported cases of disulfiram hepatitis in the literature. Liver histology, when available, demonstrates some degree of portal inflammation with eosinophils and hepatocyte necrosis. We present here a well-documented case of acute hepatitis due to disulfiram with typical histological lesions, favorable outcome following drug withdrawal, and a brief steroid course. The risk of hepatotoxicity should be kept in mind when prescribing disulfiram.

ObjectiveA case of agomelatine-induced hepatotoxicity is described in a 47-year female patient who has received the drug, 25 mg/day, for 4 months, for the treatment of depression.MethodsThe patient was admitted to the Department of Gastroenterology because of fatigue and nausea, with concomitant elevation of alanine aminotransferase (ALT), 550 U/L, and asparagine aminotransferase (AST), 300 U/L.ResultsLiver biopsy showed diffuse lymphocyte infiltration in the dilated portal spaces without lesion of hepatic lobules. Several weeks after stopping agomelatine, the liver enzymes returned to normal. Subsequently, small gallstones in common bile duct were detected and removed by the endoscopic sphincterotomy.ConclusionsIt is hypothesized that choledocholithiasis could theoretically increase a risk of developing agomelatine-induced hepatotoxicity in this patient. Any pre-existing liver disease should be a contraindication for treatment with agomelatine.

Approximately 70,000 people are infected with hepatitis C virus in Hungary, and more than half of them are not aware of their infection. From the point of infected individuals early recognition and effective treatment of related liver injury may prevent consequent advanced liver diseases and complications (liver cirrhosis, liver failure and liver cancer) and can increase work productivity and life expectancy. Furthermore, these could from prevent further spread of the virus as well as reduce substantially long term financial burden of related morbidity, as a socioeconomic aspect. Pegylated interferon + ribavirin dual therapy, which is available in Hungary since 2003, can clear the virus in 40–45% of previously not treated (naïve), and in 5–21% of previous treatment-failure patients. Addition of a direct acting first generation protease inhibitor drug (boceprevir or telaprevir) to the dual therapy increases the chance of sustained viral response to 63–75% and 59–66%, respectively. These two protease inhibitors are available and financed for a segment of Hungarian patients since May 2013. Between 2013 and February 2015, other direct acting antivirals and interferon-free combination therapies have been registered for the treatment of chronic hepatitis C with a potential efficacy over 90% and typically with a short duration of 8–12 weeks. Indication of therapy includes exclusion of contraindications to the drugs and demonstration of viral replication with consequent liver injury, i.e., inflammation and/or fibrosis in the liver. Non-invasive methods (elastography and biochemical methods) are accepted and preferred for staging liver damage (fibrosis). For initiation of treatment accurate and timely molecular biology tests are mandatory. Eligibility for treatment is a subject of individual central medical review. Due to budget limitations therapy is covered only for a proportion of patients by the National Health Insurance Fund. Priority is given to those with urgent need based on a Hungarian Priority Index system reflecting primarily the stage of liver disease, and considering also additional factors, i.e., activity and progression of liver disease, predictive factors of treatment and other special issues. Approved treatments are restricted to the most cost-effective combinations based on the cost per sustained viral response value in different patient categories with consensus between professional organizations, National Health Insurance Fund and patient organizations. More expensive therapies might be available upon co-financing by the patient or a third party. Interferon-free treatments and shorter therapy durations preferred as much as financially feasible. A separate budget is allocated to cover interferon-free treatments for the most-in-need interferon ineligible/intolerant patients, and for those who have no more interferon-based therapy option. Orv. Hetil., 2015, 156(9), 343–351.
