Nonalcoholic Fatty Liver Disease Association with Hospital and Icu Admission in Covid-19

ABSTRACT

INTRODUCTION: Association between non-alcoholic fatty liver disease (NAFLD) and metabolic-associated fatty liver disease (MAFLD) with COVID-19 is still an ongoing debate. We aimed to conduct a systematic review and meta-analysis investigating the impact of NAFLD/ MAFLD on the duration of ICU and hospital stay in COVID-19 patients. METHOD(S) A systematic review of literature from January 2019- to June 2022 on databases PubMed, Cochrane, Embase, Science Direct, and Web of science was conducted. Observational studies or clinical trials were included. Studies that assessed NAFLD/ MAFLD using lab assessment, non-invasive imaging, or liver biopsy were included. The protocol of the study was registered in Prospero and Prisma guidelines were followed (Figure 1). The meta-analysis was performed using Revman software. Mantel- Haenszel odds ratio was generated to describe the overall effect size using random effect models. RESULT(S) ICU Admission A total of 37,109 patients from fifteen studies were included in the qualitative analysis. A total of 5624 patients were in the NAFLD group and 31,485 patients were in the Non-NAFLD group, where 3148 patients with COVID-19 required ICU admission. Out of these, 1098 (19.5%) were in the NAFLD group and 2050 (6.5%) in the Non-NAFLD group. We observed a significantly increased ICU admission among COVID-19 patients with NAFLD compared to those without NAFLD (OR 1.67, 95%CI 1.02- 2.72, p-value= 0.04). (Figure 2). Hospital Admission A total of 27,683 patients from three studies were included in the qualitative analysis. A total of 1128 patients in the NAFLD group and 26,555 patients in the Non-NAFLD group, where 4019 patients with COVID-19 required hospital admission. Out of these, 518 (45.9%) were in the NAFLD group and 3501(13.1%) in the Non-NAFLD group. We observed a significant increase in hospital admissions among COVID-19 patients with NAFLD compared to those without NAFLD (OR 2.71, 95%CI 1.10-6.70, p-Value=0.03). CONCLUSION(S) The NAFLD patients may have increased ICU and hospital admission compared to Non-NAFLD Patients. Fatty liver disease has an association with increased healthcare admission and critical care service utilization among COVID-19 patients.
