Abstract :

Recurrent hypokalaemia with osteomalacia with distal renal tubular acidosis secondary to serologically positive over lap syndrome is a rare entity. A female patient aged 29 years presented with sudden onset of weakness of all four limbs, on evaluation hypokalemia was evident and treated accordingly after which she recovered, but complained of generalized myalgias and was having waddling gait. X–ray pelvis with femur showed fracture, on further evaluation investigations revealed distal renal tubular acidosis. Serologically there was evidence of overlap syndrome (MCTD) which was the cause for renal tubular acidosis.
