Inflammatory cytokines are associated to lower glomerular filtration rate in patients with hypertensive crisis.

Introduction: Hypertension and kidney function are closely related. However, there are few studies on renal function during acute elevation of blood pressure (BP), denominated hypertensive crisis (HC).

Objectives: To evaluate the relationship between renal function and inflammatory cytokines in HC, subdivided into hypertensive urgency (HUrg) and emergency (HEmerg).
