COVID-19 and ethnicty: Does reduced responsiveness to glucocorticiods explain the more aggressive nature of disease among minorities?

Marked ethnic variations in complications and mortality have been noted following infection with COVID-19, In the United States, the age-adjusted mortality rate among Blacks is 3.8 times, Hispanics 2.5 times, and Asians 1.5 times higher than Whites. In the United Kingdom, the age-adjusted mortality rate among Blacks is 2.9 times, Pakistani and Bangladeshi 2.2 times, and South Indians 1.8 times than that of Whites. One should consider that the increased mortality seen in BAME may be a consequence of impaired glucocorticoid sensitivity stemming from several intrinsic reasons such as chronic social stress and lower circulating levels of Vitamin D. This study aims to evaluate the effect, or lack thereof, of glucocorticoids on Black, Asian and Minority ethnic groups (BAME) when compared to White populations in the setting of COVID-19 treatment.
