The Perfect Storm: COVID-19 Health Disparities in US Blacks.

Coronavirus disease 2019 (COVID-19) accounts for over 180,000 deaths in the USA. Although COVID-19 affects all racial ethnicities, non-Hispanic Blacks have the highest mortality rates. Evidence continues to emerge, linking the disproportion of contagion and mortality from severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), a result of adverse social determinants of health. Yet, genetic predisposition may also play a credible role in disease transmission. SARS-CoV-2 enters cells by interaction between SARS-CoV-2 spike protein and the receptor molecule angiotensin converting enzyme 2 (ACE2) expressed on the surface of the target cells, such that polymorphisms and the expression level of ACE2 influence infectivity and consequent pathogenesis of SARS-CoV-2. Genetic polymorphisms in other multiple genes, such as acetylcholinesterase (AChE) and interleukin-6, are also closely associated with underlying diseases, such as hypertension and type 2 diabetes mellitus, which substantially raise SARS-CoV-2 mortality. However, it is unknown how these genetic polymorphisms contribute to the disparate mortality rates, with or without underlying diseases. Of particular interest is the potential that genetic polymorphisms in these genes may be influencing the disparity of COVID-19 mortality rates in Black communities. Here, we review the evidence that biological predisposition for high-risk comorbid conditions may be relevant to our ability to fully understand and therefore address health disparities of COVID-19 deaths in Blacks.

Adherence to Treatment by African Americans Undergoing Hemodialysis.

End stage renal disease (ESRD) affects African Americans more than any other ethnic group. Adherence is a challenge. Patients with ESRD must adhere to medication, diet, fluid restrictions, and dialysis treatment schedules if they do not receive a kidney transplant. The purpose of this exploratory, descriptive study was to assess adherence in 120 African Americans with ESRD undergoing hemodialysis (HD). Participants completed a demographic questionnaire and the ESRD Adherence Questionnaire (ESRD-AQ). Biomarkers were collected from medical records. Few participants (24%) adhered to dietary restrictions; however, fluid restriction was reported as the most difficult to manage, which was consistent with the interdialytic weight gain biomarker. Older participants were more adherent. Participants were adherent with HD attendance and medication. Participants reported frequent communication with the healthcare team, but a more formal process needs to be implemented with follow up to ensure understanding and reinforce adherence.

Gastrointestinal Symptoms among African Americans Undergoing Hemodialysis.

The incidence of end stage renal disease is more than three times higher in African Americans. Treatment regimens contribute to gastrointestinal (GI) complaints. This study's purpose was to examine the incidence of GI symptoms in African-American patients undergoing hemodialysis. Younger participants were more likely to report mild indigestion, while older participants reported severe indigestion or none at all. Females were more likely to report gastrointestinal symptoms. Commonly reported co-morbidities included hypertension, diabetes, and heart disease. Time on hemodialysis ranged from 1 to 279 months. Those who had been on hemodialysis the longest were more likely to report acid reflux, stomach rumbling and mild diarrhea. This study provides a foundation for early identification of GI symptoms in African-Americans patients undergoing hemodialysis.
