Clinical experience with saralasin infusion in hypertensive patients

Abstract

Renal arteriography gives a reliable anatomic delineation of the renal vasculature. However, the presence of renal arterial disease does not determine the physiologic significance of the lesion. The intravenous infusion of saralasin, a specific angiotensin II antagonist, has been investigated as a method for identifying patients with hypertension dependent upon excessive angiotensin II activity. Correlations between the blood pressure response to saralasin infusion, peripheral and differential renal vein plasma renin levels and renal angiography have been obtained in 35 hypertensive patients. The results suggest that a hypotensive response to saralasin infusion provides an adjunct to renin determinations for recognizing angiotensinogenic renovascular hypertension. However, false negative responses to saralasin occur. The reasons for these negative responses need to be determined before saralasin infusion can be employed as the sole screening test for renovascular hypertension.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
