Vitamin D Toxicity

ABSTRACT A case of marked sensitivity to vitamin D, is discussed. The reason for the occurrence of hypercalcaemic crisis three weeks after the beginning of treatment with 100 000 units of vitamin D is unknown. The possibility that either lack of thyrocalcitonin or synergism with a tumour produced parathormone-like substance played a role in the hypersensitivity to calciferol is suggested. The important but rarely reported electrocardiographic pattern of extreme hypercalcaemia was noted.

Vitamin D Toxicity

Attempts at management of idiopathic hypoparathyroidism with vitamin D have led to various reports of resistance to therapy,1 different responses to vitamin D preparations,2 and unexplained toxicity.3 We report a patient with idiopathic hypoparathyroidism who was persistently hypocalcemic during ten months of treatment with vitamin D, 150,000 units/day. After voluntary weight reduction he became hypercalcemic on the same dose of vitamin D. We believe that the toxicity in this instance was due to release of stored vitamin D into the circulation. CASE REPORT The patient was referred to the hospital at 12½ years of age because of intracranial calcifications noted on roentgenograms obtained for the evaluation of sinusitis.

Posterior reversible encephalopathy syndrome (PRES) is a clinico-radiological entity described by Hinchey et al in late 90’s, characterised by variable associations of seizure activity, consciousness impairment ranging from confusion to coma, headaches, visual abnormalities, nausea/vomiting and focal neurological signs. Common causes are accelerated hypertension, eclampsia, preeclampsia, cytotoxic drug use and autoimmune diseases like systemic lupus erythematosus.We report a case of PRES in a 62-year-old female patient due to hypercalcemia secondary to vitamin D toxicity on treatment with calcium supplements and vitamin D for secondary hypoparathyroidism. She had seizures and visual defects on presentation which recovered completely with treatment of hypercalcemia.
