Renin
-angiotensin-aldosterone (RAA) function was studied in children with secondary hypertension of 2 varieties: vasorenal hypertension (VRH) and arterial hypertension (AH) associated with chronic
pyelonephritis
. Children with VRH showed RAA activation that depended on the duration of the disease for its markedness. A direct correlation found between ABP, on the one hand, and plasma renin activity and blood aldosterone level, on the other, is evidence of the latter's involvement in VRH pathogenesis. In AH that is due to chronic
pyelonephritis
, RAA activation was also demonstrated, however, its pathogenetic involvement was only documented in children with urinary passage disorders (vesico-renal reflux), whereas in the rest RAA activation was not a primary cause of BP elevation.

The distribution of renin in two cases of segmental renal hypoplasia was investigated by immunofluorescence and the peroxidase anti-peroxidase (PAP) method using an anti-human renin antiserum.
Renin
-containing cells were found only in hypoplasic segments in the vicinity of altered glomeruli and small arteries. Well-preserved renal cortex and areas of chronic atrophic
pyelonephritis
failed to show any demonstrable site of renin production. Whatever is the mechanism of the disease, the characterization of large numbers of renin-containing cells in the affected kidney support a role for the renin-angiotensin system stimulation in this form of hypertension.
