Background: Hypertension is more prevalent in the African American population when compared with the European American population in the United States. Unprovoked hypokalemia may lead to hypertension and is associated with several forms of recognized secondary hypertension.

Methods: We investigated the association of ethnicity with unprovoked hypokalemia in the second Atherosclerosis Risk in Communities (ARIC) study examination. Hypokalemia was defined as serum potassium <3.5 mmol/L.

Results: A statistically significant association was detected between ethnicity and unprovoked hypokalemia (odds ratio = 5.3; 95% confidence interval = 3.6, 7.7) with unprovoked hypokalemia more prevalent in African Americans both before and after adjustment for important covariates. The unadjusted prevalence for unprovoked hypokalemia was 2.6% for African Americans and 0.5% for European Americans.

Conclusions: We found that the prevalence of unprovoked hypokalemia for African Americans in the ARIC cohort was more than five times that for European Americans. These data suggest that an increased awareness of hypokalemia and its etiology may be indicated for African Americans.

Pulmonary embolism as the presenting symptom and a confounder in ACTH-secreting bronchial carcinoid.

Endocrinol Diabetes Metab Case Rep

July 2019

Division of Endocrinology, Department of Internal Medicine

Summary: Ectopic ACTH-secreting pulmonary neuroendocrine tumors are rare and account for less than 5% of endogenous Cushing’s syndrome cases. We describe an unusual case of metastatic bronchial carcinoid tumor in a young woman presenting with unprovoked pulmonary emboli, which initially prevented the detection of the primary tumor on imaging. The source of ectopic ACTH was ultimately localized by a Gallium-DOTATATE scan, which demonstrated increased tracer uptake in a right middle lobe lung nodule and multiple liver nodules.

We present the case of a young patient with hypertension and unprovoked symptomatic hypokalemia. His workup uncovered secondary aldosteronism, moderate proteinuria, and, quite unusually, concurrent chronic hepatitis B. Detailed investigations, including renal angiography, renal vein sampling, and kidney biopsy, showed unilateral renin hypersecretion due to intrarenal arterial stenoses and mesangioproliferative glomerulonephritis, presumed to be secondary to hepatitis B infection.

Most patients with hypertension in the United States have essential (primary) hypertension (95%), the cause of which is unknown. The remaining 5% of adults with hypertension have the secondary form of hypertension, the cause and pathophysiologic process of which are known. Internists and other primary care physicians refer to this as treatable or curable hypertension, because the hypertension can be managed or even controlled with medications.
