ABSTRACT
The coronavirus disease 2019 (COVID-19) is caused by the severe acute respiratory syndrome coronavirus2 (SARS-CoV-2) virus. COVID-19 affected more than 6million persons worldwide in fewer than 4 months, after the report of the first cases in China in December 2019. The relation of the disease caused by SARS-Cov-2 to immunosuppressive treatment used in different gastrointestinal disorders is uncertain, resulting in debate with regard to suspending immunosuppressive therapy to improve infection outcome. Said suspension implies the inherent risk for graft rejection or autoimmune disease exacerbation that can potentially worsen the course of the infection. Based on the presently available evidence, a treatment stance has been established for patients with gastrointestinal diseases that require immunosuppressive therapy.

Understanding of the pathophysiology of hepatic encephalopathy has conditioned new treatment options. Ammonia detoxification in hepatic encephalopathy is regulated by two enzymes: glutaminase or glutamine synthetase. The first produces ammonia and the second detoxifies the ammonia, which is why treatments are aimed at glutaminase inhibition or glutamine synthetase activation. At present, we know that both enzymes are found not only in the liver, but also in the muscle, intestine, kidney, and brain. Therefore, current treatments can be directed at each enzyme at different sites. Awareness of those potential treatment sites makes different options of approach possible in the patient with hepatic encephalopathy, and each approach should be personalized.
