Influence of the drugs used in migrant patients with severe acute respiratory syndrome coronavirus 2 and the development of symptomatic strongyloidiasis

Abstract Background The use of dexamethasone in patients infected with Strongyloides stercoralis can cause severe complications. It is necessary to investigate the relationship between coronavirus disease 2019 (COVID-19) and strongyloidiasis infection. Methods A retrospective, longitudinal, descriptive study was undertaken to review all patients admitted with a diagnosis of COVID-19 infection at the Complejo Asistencial Universitario de Salamanca, Spain, during 1 March–31 December 2020. Results A total of 2567 patients received a diagnosis of COVID-19. Eighty-six patients from endemic areas were included. Seven patients had strongyloidiasis. Five patients were female. The mean age (±SD) was 39 (±10.8) y. Six patients were Latin-American and only one patient was from Africa. Six patients had previous symptoms compatible with strongyloidiasis infections. Only three patients received dexamethasone (6 mg once daily) for 10 d. In all cases, the clinical courses of the patients were satisfactory. No patient died or was admitted to the ICU. Conclusions Screening programmes using serological techniques should be implemented in COVID-19 patients to prevent strongyloidiasis. Our study suggested that drugs used against COVID-19 in patients with strongyloidiasis did not affect the evolution of the disease. However, more studies are necessary to elucidate the role of dexamethasone in COVID-19 patients infected with Strongyloides.
