“…We have also compared our results with previous meta‐analysis (Table 3). 4,5,119‐125 This is the first study to report the liver involvement of all adults, pregnant patients and paediatric patients with COVID‐19. We have analysed in‐depth about the liver involvement in COVID‐19, including elevated liver chemistries at initial presentation, during illness and the impact of this on the outcome.…”

Summary Background The incidence of elevated liver chemistries and the presence of pre‐existing chronic liver disease (CLD) have been variably reported in COVID‐19. Aims To assess the prevalence of CLD, the incidence of elevated liver chemistries and the outcomes of patients with and without underlying CLD/elevated liver chemistries in COVID‐19. Methods A comprehensive search of electronic databases from 1 December 2019 to 24 April 2020 was done. We included studies reporting underlying CLD or elevated liver chemistries and patient outcomes in COVID‐19. Results 107 articles (n = 20 874 patients) were included for the systematic review. The pooled prevalence of underlying CLD was 3.6% (95% CI, 2.5‐5.1) among the 15 407 COVID‐19 patients. The pooled incidence of elevated liver chemistries in COVID‐19 was 23.1% (19.3‐27.3) at initial presentation. Additionally, 24.4% (13.5‐40) developed elevated liver chemistries during the illness. The pooled incidence of drug‐induced liver injury was 25.4% (14.2‐41.4). The pooled prevalence of CLD among 1587 severely infected patients was 3.9% (3%‐5.2%). The odds of developing severe COVID‐19 in CLD patients was 0.81 (0.31‐2.09; P = 0.67) compared to non‐CLD patients. COVID‐19 patients with elevated liver chemistries had increased risk of mortality (OR‐3.46 [2.42‐4.95, P < 0.001]) and severe disease (OR‐2.87 [95% CI, 2.29‐3.6, P < 0.001]) compared to patients without elevated liver chemistries. Conclusions Elevated liver chemistries are common at presentation and during COVID‐19. The severity of elevated liver chemistries correlates with the outcome of COVID‐19. The presence of CLD does not alter the outcome of COVID‐19. Further studies are needed to analyse the outcomes of compensated and decompensated liver disease.

“…Chinese data on patients with SARS-CoV-2 infection report a prevalence of abnormal liver test as high as 76.3%, while the prevalence in Western patients seems to be lower. [1][2][3][4] However, these studies report baseline or short-term follow-up evaluations. Therefore, the evolution of liver involvement, its correlation with patients' mortality or resolution of SARS-CoV-2 infection is still unknown.…”

Summary Background Severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infection is frequently associated with liver test abnormalities. Aims To describe the evolution of liver involvement during SARS‐CoV‐2 infection and its effect on clinical course and mortality. Methods Data of 515 SARS‐CoV‐2‐positive patients were collected at baseline and during follow‐up, last evaluation or death. Stratification based on need for hospitalisation, severe disease and admission to intensive care unit (ICU) was performed. The association between liver test abnormalities (baseline and peak values) and ICU admission or death was also explored. Results Liver test abnormalities were found in 161 (31.3%) patients. Aspartate aminotransferase (AST), alanine aminotransferase (ALT) and gamma glutamyl transferase (GGT) were increased in 20.4%, 19% and 13.6% of patients, respectively. Baseline liver test abnormalities were associated with increased risk of ICU admission (OR 2.19 [95% CI 1.24‐3.89], P = 0.007) but not with mortality (OR 0.84 [95% CI 0.49‐1.41], P = 0.51). Alkaline phosphatase (ALP) peak values were correlated with risk of death (OR 1.007 [95% CI 1.002‐1.01], P = 0.005) along with age, multiple comorbidities, acute respiratory distress syndrome, ICU admission and C‐reactive protein. Alterations of liver tests worsened within 15 days of hospitalisation; however, in patients with the longest median follow‐up, the prevalence of liver test alterations decreased over time, returning to around baseline levels. Conclusions In SARS‐CoV‐2‐positive patients without pre‐existing severe chronic liver disease, baseline liver test abnormalities are associated with the risk of ICU admission and tend to normalise over time. The ALP peak value may be predictive of a worse prognosis.
