We present this rare occurrence of a 17 yr old boy, a known case of congenital hypoparathyroidism, who presented with fever and jaundice for 8 days and 2 episodes of generalised tonic-clonic seizures. Premorbidly patient was on regular oral calcium supplementations with normal serum calcium levels. Investigations revealed severe hypocalcaemia (3.2 mg/dL), low 25 hydroxyvitamin D levels and hypomagnesaemia. The marked elevation of serum bilirubin was accompanied by derangement of liver enzymes. Microbiological investigations were confirmatory for both hepatitis A and typhoid fever. In spite of the aggressive management with intravenous calcium gluconate infusion, refractory hypocalcaemia persisted with recovery only after gradual decline in the bilirubin levels. We inferred that the cholestatic process produced by both acute viral hepatitis A and typhoid fever precipitated this state of refractory hypocalcaemia in the previously well preserved patient.
