Authors
Identification of risk factors for severe outcome of SARS-CoV-2 infection is an important issue in COVID-19 management. Much attention has been focused on comorbidities as well as drugs taken by patients. Usage of proton pump inhibitors (PPIs) appears to potentially influence disease course. These drugs are known to reduce stomach acid and also modulate the immune system. Their use, prior to and during COVID-19 infection, seems to predispose to the development of more severe pneumonia and therefore to a greater risk of mortality. Instead, the use of histamine receptor 2 antagonists (H2RAs) seems to be associated with a better outcome in patients with COVID-19, in terms of symptoms, risk of intubation and death. As PPIs are essential for treatment of many disorders, usage of these drugs should be balanced considering the benefits and risk ratio, in order to guarantee their correct use for the necessary time. It remains to be clarified whether the detrimental effects, in terms of COVID-19 severe outcome, are due to PPIs or to the underlying disease for which they are administered. New controlled-randomized trials are required to better understand their impact in SARS-CoV-2 infections.
