title: Furosemide and dDAVP for the treatment of pseudohypoaldosteronism type II.
abstract: A 27-year-old Turkish male presented with fatigue, long lasting hypertension, hyperkalemia, hyperchloremic metabolic acidosis and normal glomerular filtration rate. His brother also showed hyperkalemia with no other features of the disease. Plasma renin levels were low and serum aldosterone levels were inappropriately low-normal to his hyperkalemia. Plasma cortisol levels were normal. Plasma renin aldosterone levels responded appropriately to postural changes, salt restriction and saline infusion. Fludrocortisone was ineffective in his hyperkalemia. The conditions were consistent with Type II pseudohypoaldosteronism (PHA). Furosemide and sodium bicarbonate were effective to control his hyperchloremia, metabolic acidosis and hypertension but partly effective for his hyperkalemia. dDAVP alone did not control the situation and hypertension and metabolic derangement reoccurred. Adding dDAVP to furosemide and sodium bicarbonate successfully controlled hyperkalemia, hyperchloremic acidosis and hypertension. The patient stayed normotensive with normal metabolic and biochemical parameters after 6 months with furosemide and dADVP although sodium bicarbonate had been discontinued after the first month of therapy. dDAVP is a useful adjunct to furosemide and non chloride anions which altogether successfully reverse the metabolic derangement in Type II PHA.
