ARTICLE HIGHLIGHTS
Research background

Coronavirus disease 2019 (COVID-19) may be asymptomatic or cause mild to severe symptoms exacerbated by preexisting health conditions like liver diseases. However, the relation between hepatic diseases and the effect and prognosis of COVID-19 individuals is unclear, and information concerning the Portuguese population is scarce.

Research motivation

To understand how hepatic disorders may have been affected by COVID-19 and how this infection impacted the Portuguese healthcare system.

Research objectives

To investigate the association between COVID-19 and liver diseases and their impact on the prognosis of patients and explore the effect of COVID-19 on healthcare systems.

Research methods

A review of the relevant literature was performed.

Research results

People with liver diseases who were COVID-19-positive had a worse prognosis than individuals without hepatic diseases. Due to COVID-19, most countries altered the normal activity of healthcare systems, increasing teleconsultations.

Research conclusions

The interaction between liver diseases and COVID-19 in people's prognosis is unclear, but there is evidence of its existence. As observed in other countries, the normal activity of the national healthcare system in Portugal was modified due to the pandemic situation created by COVID-19.

Research perspectives

To promote the development of studies about the interaction and relation between liver diseases and COVID-19 and generate critical thinking about how healthcare systems should function in case of a pandemic.
