ABSTRACT

BACKGROUND: Coronavirus disease 2019 (COVID-19) has infected over 2 million people worldwide over the course of just several months. Various studies have highlighted that patients infected with COVID-19 may develop various degrees of liver injury. Here, we discuss the impact of underlying liver disease and manifestations of hepatic injury with COVID-19. We also review mechanisms of hepatic injury. METHODS: We searched the database PubMed for all studies focused on hepatic injury in COVID-19. RESULTS: We identified 13 studies that assessed the impact of underlying liver disease in patients infected with COVID-19 (N=3046). Underlying liver disease was one of the most common known comorbid categories in patients infected with COVID-19. Overall, 25% of the patients identified from the 13 studies had hepatic injury. Twenty-one percent and 24% had elevated alanine transaminase and aspartate transaminase values, respectively. Nine percent of the patients had elevated total bilirubin values. Ten of the 13 studies assessed COVID-19 acuity with severity of hepatic injury. In 9 of the 10 studies, clinical outcomes were worse with hepatic injury. CONCLUSIONS: Liver injury is highly prevalent in patients that present with COVID-19. Since the liver is one of the most affected organs outside of the respiratory system in COVID-19, more intensive surveillance is warranted for severe cases, particularly among those with pre-existing advanced liver disease.

ABSTRACT

BACKGROUND: Coronavirus disease 2019 (COVID-19) has rapidly become a major international public health concern. This study was designed to evaluate the clinical characteristics and risk factors of COVID-19-associated liver injury. METHODS: A fraction of 657 COVID-19 patients were retrospectively analyzed. Clinical and laboratory data were derived from electronic medical records and compared between patients with or without liver injury. Multivariate logistic regression method was used to analyze the risk factors for liver injury. RESULTS: Among 657 patients, 303 (46.1%) patients had liver injury with higher rate in severe/critically ill patients [148/257 (57.6%)] than those in moderate cases [155/400 (38.8%)]. The incidence of liver injury was much higher in male [192/303 (63.4%)] than female [111/303 (36.6%)], and in severe/critical patients [148/303 (48.8%)] with percutaneous oxygen saturation ≤ 93% [89/279 (31.9%)] or peak body temperature ≥ 38.5 °C [185/301 (61.5%)] on admission. Liver injury-related inflammations included increased white blood cells, neutrophils and decreased lymphocytes. More patients with liver injury than without had increased serum IL-2R, TNFα, ferritin, hsCRP, PCT, ESR, γ-GT, and LDH. Multivariate regression analysis revealed that increasing odds of liver injury were related to male, higher serum hsCRP (≥ 10 mg/L), and neutrophil-to-lymphocyte ratio (NLR) (≥ 5). Moreover, more deceased patients (14/82 (17%)) had significantly elevated serum TBIL than discharged patients [25/532 (4.7%)]. CONCLUSION: Liver injury is a common complication in COVID-19 patients. The potential risk factors of liver injury include male, hsCRP and NLR score. A close monitor of liver function should be warned in COVID-19 patients, especially in severe/critical individuals.

ABSTRACT

BACKGROUND AND AIMS: Coronavirus disease 2019 (COVID-19) pandemic is ongoing. Except for lung injury, it is possible that COVID-19 patients develop liver injury. Thus, we conducted a systematic review and meta-analysis to explore the incidence, risk factors, and prognosis of abnormal liver biochemical tests in COVID-19 patients. METHODS: PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP, and Wanfang databases were searched. The incidence of abnormal liver biochemical tests, including aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), gamma-glutamyl transpeptidase (GGT), total bilirubin (TBIL), and albumin (ALB), was pooled. Risk ratio (RR) was calculated to explore the association of abnormal liver biochemical tests with severity and prognosis of COVID-19 patients. RESULTS: Forty-five studies were included. The pooled incidence of any abnormal liver biochemical indicator at admission and during hospitalization was 27.2% and 36%, respectively. Among the abnormal liver biochemical indicators observed at admission, abnormal ALB was the most common, followed by GGT, AST, ALT, TBIL, and ALP (39.8%, 35.8%, 21.8%, 20.4%, 8.8%, and 4.7%). Among the abnormal liver biochemical indicators observed during hospitalization, abnormal ALT was more common than AST and TBIL (38.4%, 28.1%, and 23.2%). Severe and/or critical patients had a significantly higher pooled incidence of abnormal liver biochemical indicators at admission than mild and/or moderate patients. Non-survivors had a significantly higher incidence of abnormal liver biochemical indicators than survivors (RR = 1.34, p = 0.04). CONCLUSIONS: Abnormal liver biochemical tests are common in COVID-19 patients. Liver biochemical indicators are closely related to the severity and prognosis of COVID-19 patients.
