Abstract :
Rickets is a common condition affecting the paediatric patients in developing countries including India. It is usually
secondary to nutritional deficiency of vitamin D. Children are predisposed to this condition if the dietary requirements of
vitamin D are not met. This type of rickets is called nutritional rickets and it can be corrected by supplementation of vitamin
D and calcium. But there are some other rare types of rickets which are seen secondary to renal defects. These include
distal renal tubular acidosis, proximal renal tubular acidosis, vitamin D dependent rickets and hypophosphatemic rickets.
The children suffering from rickets secondary to these disorders may not respond to usual doses of calcium and vitamin D.
Proper diagnosis and management is required in these cases. We here present a case of 3 year old male child who
presented to us with delayed walking, failure to thrive, irritability, recurrent episodes of vomitings, abdominal pain and
dehydration. The patient eventually was found to be having rickets secondary to distal renal tubular acidosis.
