Dexamethasone and COVID-19: Strategies in Low- and Middle-Income Countries to Tackle Steroid-Related Strongyloides Hyperinfection.

Abstract

ABSTRACTCOVID-19 can trigger a systemic inflammatory response that in some cases leads to severe lung involvement, multisystem dysfunction, and death. Dexamethasone therapy, because of its potent anti-inflammatory effects, has been proposed for the management of hospitalized patients with severe COVID-19. The subject of this article is to discuss potential strategies to tackle Strongyloides hyperinfection in hospitalized patients with COVID-19 receiving dexamethasone therapy in low- and middle-income countries. In this context, dexamethasone treatment has been found to be generally safe. However, its use in people coinfected with undetected Strongyloides stercoralis increases the risk for Strongyloides hyperinfection/dissemination a potentially fatal complication. Infection caused by S. stercoralis may remain asymptomatic or with mild symptoms in humans for several years. Early detection and specific treatment prevent a fatal evolution of this complication, but the challenge is to screen before corticosteroid therapy. In some cases, presumptive treatment may be justified. Ivermectin is the gold standard for treatment.
