Prostaglandin excretion in pseudohypoaldosteronism type I.
In an infant with pseudohypoaldosteronism type I increased urinary excretion of PGE2 (1.32 ng/mg creatinine; normal mean +/- SE: 0.50 +/- 0.10) and PGF2 alpha (6.15 ng/mg creatinine; normal mean +/- SE: 2.93 +/- 0.91) was found. Prostaglandin excretion as well as the typical hyperkalemia, hyperreninemia and hyperaldosteronism normalized with adequate dietary salt supplementation. An abnormally high excretion of the renal prostaglandins was again present at age 4.4 years when the child was thriving although additional salt was withheld. These abnormalities are considered to be secondary to this condition's basic defect which remains to be elucidated.
