[Function of the kallikrein-kinin and prostaglandin systems of the kidneys in patients with chronic pyelonephritis].

The activity of the kallikrein-kinin, prostaglandin and cyclase systems was assessed in 117 patients with chronic pyelonephritis with and without arterial hypertension. Pyelonephritis is shown to be associated with a dysfunction of the pressor-depressor mechanisms examined, featuring a depression of vasodepressor reactions. Patients with normal, increased and depressed humoral parameters could be found in each study group, the changes being particularly marked in patients with chronic pyelonephritis, combined with arterial hypertension.
