• | The impact of SARS-CoV-2 infection on liver function and structure is not well established. |
• | Our findings suggest that exposure to SARS-CoV-2 does not determine long-term structural and functional changes in the liver. |
• | Variation in TyG index as a surrogate of insulin resistance and an indicator of metabolic dysfunction is related to that of steatoscore2.0. |
Abstract |
Background & Aims |
Severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) binds to Angiotensin Converting Enzyme – 2 (ACE2) receptor targeting various organs including liver. Liver injury is a common feature of SARS-CoV-2 acute infection. A few studies have also described chronic hepatic alterations in patients with previous COVID-19. We hypothesize that steatosis seen in COVID-19 patients reflects their metabolic profile and is not caused by persistent inflammation sustained by SARS-CoV-2.
Methods |
We conducted a prospective study to evaluate long-term changes in liver function and structure in patients hospitalized for COVID-19. Patients without a prior known hepatic disease with mild to moderate COVID-19 were enrolled during hospitalization and reevaluated during a follow-up visit at a medium 16 months. Complete blood panels with metabolic profile, BMI, alcohol consumption and physical activity were compared between baseline and follow-up. Specific ultrasound scans were obtained during hospital stay and at follow-up to quantify steatosis using Steatoscore2.0.
Results |
Among 55 eligible patients, 33 were included in the analysis and only 3 (9 %) had a new diagnosis of steatosis at follow-up. Steatoscore2.0 did not change significantly from baseline to follow-up (1.7 vs 1.73, p = 0.348), while changes occurred in body mass index and physical activity estimated by IPAQ questionnaire (26.3 vs 26.6 kg/m2, p = 0.005; 540 vs. 480, p = 0.015, respectively). There was a statistically significant increase in total cholesterol (144.5 vs 187.0 mg/dl, p = 0.003) and low-density lipoprotein-cholesterol (73.8 vs 113.9 mg/dl, p = 0.003). Inflammatory markers normalized at follow-up, including C-reactive protein (41.1 vs. 0.8 mg/L, p < 0.001), and ferritin (410.0 vs. 91.0 ng/dl, p < 0.001). Four patients had a 3-time rise in liver transaminase levels at baseline, and this was not confirmed at follow-up. Change in Steatoscore2.0 correlated significantly with Triglyceride-glucose index as a surrogate of insulin resistance.
Conclusions |
In our study, long term functional and structural changes were not observed in patients with previous SARS-CoV-2 infection. There was a significant deterioration of metabolic profile post COVID-19
