ABSTRACT

Background: The role of liver function tests (LFT) as prognostic factors in patients admitted with COVID-19 has not been fully investigated, particularly outside resource-rich countries. We aimed at evaluating the prognostic value of abnormal LFT on admission and during hospitalization of patients with COVID-19. Methods: We performed a retrospective study that included 298 adult patients hospitalized for COVID-19, between 05/2020 and 02/2021, in 6 hospitals from 5 countries in South America. We analyzed demographic and comorbid variables and laboratory tests on admission and during hospitalization. LFT over twice the upper limit of normal (ALEx2) were also evaluated in relation to a variety of factors on admission and during hospitalization. De novo-ALEx2 was defined as the presence of ALEx2 at one week of hospitalization in patients without ALEx2 on admission. Patients were followed until hospital discharge or death. Multivariable analysis was used to evaluate the association between ALEx2 on admission and during hospitalization and mortality. Results: Of the total of 298 patients, 60% were male, with a mean age of 60 years, and 74% of patients had at least one comorbidity. Of those, 137 (46%) patients were transferred to the intensive care unit and 66 (22.1%) patients died during hospitalization. ALEx2 on admission was present in 87 (29.2%) patients and was found to be independently associated with 1-week mortality (odds ratio (OR) = 3.55; 95% confidence interval (95%CI) 1.05-12.05). Moreover, 84 (39.8%) out of 211 patients without ALEx2 at admission developed de novo-ALEx2, which was independently associated with mortality during second week of hospitalization (OR = 6.09; 95%CI 1.28-29) and overall mortality (OR = 2.93, 95%CI 1.05-8.19). Conclusions: A moderate elevation of LFT during admission was associated with a poor short-term prognosis in patients hospitalized with COVID-19. In addition, moderate elevation of LFT at one week of hospitalization was an independent risk factor for overall mortality in these patients.

ABSTRACT

Infection with hepatitis E virus (HEV) leads to acute hepatitis infection in immunocompetent hosts. HEV genotype 3 can present with high frequency and lead to chronic infection in individuals with a compromised immune system. The risk factors related to increased seroprevalence or chronicity in this population are not entirely understood. Moreover, most studies addressing risk factors for HEV in non-endemic areas come from developed areas such as North America and Europe. In this study we evaluated seroprevalence, chronicity and risk factors for HEV in 120 transplant recipients and 88 patients on dialysis in Argentina. We found a significantly higher seroprevalence of HEV IgG in those undergoing dialysis compared with healthy controls (10.2% and 4.3% respectively, p = 0.03). No difference in HEV seroprevalence was observed between healthy controls and transplant recipients (5.8%). We found no association between previously identified risk factors for HEV, such as pork consumption or use of tacrolimus, and HEV seroprevalence. In univariate and multivariate analyses, consumption of fish was associated with higher seroprevalence of HEV (OR = 9.33; 95% CI: 2.07-42.2; p = 0.04). None of the samples showed HEV RNA amplification, indicating that chronicity does not seem to be an issue in these cohorts. Our results show increased seroprevalence of HEV in individuals undergoing dialysis but not in transplant recipients. We also found that fish consumption can be a potential risk factor for acquiring HEV.
