A case report of distal RTA presenting as hypokalaemic periodic paralysis in young male

Abstract

A 21-year-old normotensive male presented with acute onset flaccid paralysis with the history of a similar episode a few months back. Clinical and laboratory evaluation revealed lower motor neuron type of flaccid quadriparesis with hypokalaemia, normal anion gap metabolic acidosis, bicarbonaturia, and transtubular potassium concentration gradient (TTKG) more than 7. Subsequently urine acidification test (by NH4CI challenge test) was done and diagnosis of distal renal tubular acidosis was established. The patient responded to conservative management (Sohl′s solution).
