Tackling the Disproportionate Burden of Resistant Hypertension in US Black Adults.

PURPOSE OF REVIEW: Elevated blood pressure is the leading modifiable risk factor for cardiovascular morbidity and mortality in the US. Older individuals, Black adults, and those with comorbidities such as chronic kidney disease, have higher levels of uncontrolled and resistant hypertension. This review focuses on resistant hypertension, specifically in the US Black population, including potential benefits and limitations of current and investigational agents to address the disparate toll. RECENT FINDINGS: There is a necessity to implement public health measures, including early screening, detection, and evidence-based hypertension treatment with lifestyle, approved and investigational agents. The evidence highlights the importance of implementing feasible and cost-effective public health measures to advocate for early screening, detection, and appropriate treatment of hypertension. A team-based approach involving physicians, advanced practice nurses, physician assistants, pharmacists, social workers, and clinic staff to implement proven approaches and the delivery of care within trusted community settings may mitigate existing disparities.

Heterogeneity of Lung Function Phenotypes in Sarcoidosis: Role of Race and Sex Differences.

Rationale: Historically, sarcoidosis was described as a restrictive lung disease, but several alternative phenotypes of pulmonary function have been observed. Pulmonary function phenotypes in sarcoidosis may represent different clinical and/or molecular phenotypes. Objectives: To characterize the prevalence of different pulmonary function phenotypes in a large and diverse sarcoidosis cohort from a tertiary care referral center. Methods: We identified individuals seen between 2005-2015 with a confirmed diagnosis of sarcoidosis. Data were collected from the first pulmonary function test (PFT) performed at our institution which included spirometry and diffusing capacity of the lung for carbon monoxide (DlCO). Demographics and clinical data were collected. Chi-squared analyses and multiple linear regressions were done to assess statistical differences and associations. Global Lung Function Initiative equations were used to calculate percent predicted measurements for spirometry and DlCO. Results: Of 602 individuals with sarcoidosis, 93% (562) had pulmonary involvement, 64% (385) were female, and 57% (341) were Black. Of those with pulmonary involvement, 56% had abnormal pulmonary function. Lung function impairment phenotypes included: 47% restriction, 22% obstruction, 15% isolated reduction in DlCO, and 16% combined obstructive restrictive phenotype. Restriction was the most common PFT phenotype among Black individuals (41%), while no lung impairment was most common among White individuals (66%) (P < 0.001). Males more frequently had obstruction (19%) compared with females (9%) P = 0.001, and females had more restriction (30%) compared with males (21%) P = 0.031. Conclusions: Among individuals with sarcoidosis and pulmonary function impairment, less than half demonstrated a restrictive phenotype. There were significant differences in pulmonary function phenotypes by race and sex.
