ABSTRACT
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causal agent of coronavirus disease 2019 (COVID-19). Diabetes is one of the most frequent comorbidities in people with COVID-19 with a prevalence that varies between 7 and 30%. Diabetics infected with SARS-CoV-2 have a higher rate of hospital admission, severe pneumonia, and higher mortality compared to non-diabetic subjects. Chronic hyperglycemia can compromise innate and humoral immunity. Furthermore, diabetes is associated with a low-grade chronic inflammatory state that favors the development of an exaggerated inflammatory response and therefore the appearance of acute respiratory distress syndrome. Recent evidence has shown that SARS-CoV-2 is also capable of causing direct damage to the pancreas that could worsen hyperglycemia and even induce the onset of diabetes in previously non-diabetic subjects. Therapeutic strategies should be aimed at facilitating patient access to the healthcare system. Control of blood glucose and comorbidities must be individualized in order to reduce the incidence of complications and decrease the burden on health systems. In this article we will review the pathophysiological mechanisms that explain the bidirectional relationship between COVID-19 and diabetes mellitus, its implication in the prognosis and management of hyperglycemia in this group of patients.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causal agent of coronavirus disease 2019 (COVID-19). Acute respiratory distress syndrome is the main cause of death from COVID-19 and occurs due to an exaggerated inflammatory response that causes the release of pro-inflammatory cytokines such as interleukins and tumor necrosis factor-alpha (TNF-α). Statins are lipid lowering drugs with pleiotropic effects. They have shown benefit in the management of inflammatory and autoimmune diseases such as systemic lupus erythematosus, rheumatoid arthritis and multiple sclerosis. Furthermore, due to their immunomodulatory properties, they have been used in the treatment of various infectious diseases such as community-acquired pneumonia and influenza. In this review we analyze the pathophysiological foundations that support the use of statins as an adjunctive treatment in patients with COVID-19. Resumen El coronavirus tipo 2 del síndrome respiratorio agudo grave (SARS-CoV-2) es el agente causal de la enfermedad por coronavirus 2019 (COVID-19). El síndrome de distress respiratorio agudo constituye la principal causa de muerte por COVID-19 y ocurre por una respuesta inflamatoria exagerada que provoca la liberación de citocinas proinflamatorias como interleucinas y factor de necrosis tumoral alfa (TNF-α). Las estatinas son fármacos hipolipemiantes con efectos pleiotrópicos. Han demostrado beneficio en el manejo de enfermedades inflamatorias y autoinmunes como el lupus eritematoso sistémico, la artritis reumatoide y la esclerosis múltiple. Además, debido a sus propiedades inmunomoduladoras se han utilizado en el tratamiento de diversas enfermedades infecciosas como neumonía adquirida en la comunidad e influenza. En esta revisión analizamos los fundamentos fisiopatológicos que apoyan el uso de estatinas como tratamiento coadyuvante en pacientes con COVID-19.
