[Review of pseudohypoaldosteronism. Apropos of a clinical case in a 2-month-old girl].
The case of a two month-old child admitted because of dystrophy is presented. At physical examination she presented a growth retardation (-2DS) as well as cutaneous and mucosal pallor. Metabolic acidosis, hyponatremia, hyperkaliemia and salt loss were demonstrated. Aldosterone, both plasmatic and urinary, was increased. Plasma renin activity, was also increased. In respect to renal function, hypercalciuria was found but not other abnormalities neither in the renal nor suprarrenal function were noticed. The electrolytic levels in sweat, saliva and feces were also normal. The clinical and laboratory findings were not modified with the DOCA test. Spirolactone caused an increase in salt loss. Treatment with indometacine improved both the clinical and analytical findings. On the other hand, treatment with chloride sodium (4 gr p.o. per day) also improved dramatically the disturbances. In the last 12 months she has growth up normally. At the same time, the renal loss of sodium has decreased and aldosterone, both plasmatic and urinary, is not so increased as it was at diagnosis. Finally, electrolytic parameters are fully normal.
