Abstract

The effect of furosemide on urinary kallikrein excretion was studied in 10 patients with essential hypertension and 9 normal volunteer subjects. After intravenous administration of furosemide and 2 hours of upright posture, urine volume (UV), urinary sodium (UNaV) and potassium (UKV) excretion, plasma renin activity (PRA), plasma aldosterone concentration (PAC) and urinary kallikrein markedly increased. However, the augmentation of urinary kallikrein in patients with essential hypertension (1.50 +/- 0.19 EU/2 hr) was less remarkable than that in normal subjects (2.33 +/- 0.24 EU/2 hr), although the same degrees of response were observed in PRA and PAC. The increments of UV, UNaV and UKV in patients with essential hypertension were also significantly lower than in normal subjects. Significant positive relations were found between urinary kallikrein and UV or UNaV in both hypertensive and normotensive groups, but there was no such correlation before fursemide administration. It is likely that diuresis and natriuresis induced by furosemide are somehow associated with an increase in urinary kallikrein excretion. Blunted response of urinary kallikrein in essential hypertension may suggest an abnormality in the renal kallikrein-kinin...Continue Reading

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.
