Iatrogenic hypercalcemic encephalopathy due to hypervitaminosis D – A case series
Sushil Razdan
Acharya Shri Chander College of Medical Sciences, India
Vitamin D is increasingly recognized to have beneficial effects in several inflammatory conditions and there is some evidence
to suggest that it is associated with a reduced risk of various internal malignancies, aside from its classic physiologic effects
on calcium metabolism and bone homeostasis. Although vitamin D toxicity is thought to be extremely rare, and an extremely rare
cause of hypercalcemia, food and nutrition board guidelines specify 2000IU as highest vitamin D intake that healthy adults can
consume daily without risking hypercalcemia. For many people the word “vitamin” implies something that is beneficial, essential
and not potentially poisonous. But, Vitamin D is toxic in large doses and sporadic reports of vitamin D toxicity exist in literature. We
report a case series of fifteen patients with symptomatic hypercalcemia in whom toxicity occurred due to excessive administration of
vitamin D by oral and parenteral route. The most frequently noted clinical manifestations in these patients were altered sensorium.
In the present study we report a case series of 15 patients, nine women and six men, aged between 42–85 years who presented
to the Department of Medicine, Acharya Shri Chander College of Medical Sciences and Hospital, Jammu, Jammu and Kashmir
between December 2009 and September 2011. All patients were residents of Jammu and Kashmir. All the 15 patients had symptoms
attributable to hypercalcemia with elevated serum calcium and serum 25-hydroxy vitamin D3 levels. All the 15 patients were suffering
from hyper-vitaminosis D.
