Abstract #1185030: Primary Hyperparathyroidism Corrected by Vitamin D supplementation: A Rare Presentation

Abstract

Primary hyperparathyroidism (PHTP) is a common endocrine disorder characterized by high parathyroid hormone (PTH) and calcium levels, commonly detected incidentally. A common concurrent finding is vitamin D deficiency, with a reported incidence of as high 91%. Vitamin D administration in PHPT is controversial due to a risk of exacerbating hypercalcemia, though some studies have shown that this may in fact be beneficial by suppressing PTH levels and decreasing bone demineralization. We present an interesting case of a 45-year-old male presenting with asymptomatic PHPT which was successfully managed solely with vitamin D administration.
