Hyperprolactinemia as a rare cause of hypertension in chronic renal failure.

Chronic renal failure (CRF) is associated with a high risk for hypertension. An individualized treatment should be initiated after the diagnosis of hypertension and underlying etiology. Many metabolic and endocrinal abnormalities are encountered in CRF. We present an 11-year-old boy with CRF developing galactorrhea and hyperprolactinemia associated with α-methyldopa, defective dopaminergic control, and resistance to multi-antihypertensive therapy. Cabergoline, a dopamine receptor agonist, was effectively used in the treatment of hypertension. It is important to remember that sometimes treatment of an illness becomes the cause of this illness.
