Calcemia is not routinely determined among people living with human immunodeficiency virus (HIV). In people living with HIV, the most frequent electrolyte disturbance is hyponatremia and since symptoms of hypocalcemia often are unspecific, calcium is typically measured with some delay. Hypocalcemia in people living with HIV is mainly due to indirect causes such as vitamin D deficiency, renal failure, or drug related. However, in rare cases direct viral involvement of the parathyroid glands has been reported. We present a case of a 67-year-old male living with HIV who presented at an emergency department with symptomatic severe hypocalcemia, without any previous history of neck surgery, radiation therapy or large infections in the head and neck area. At the time of admission serum concentrations were for ionized calcium 0.98 mmol/L (ref. 1.18-1.32 mmol/L) and PTH 1.3 mmol/L (ref. 2.0-8.5 pmol/L). Vitamin D status was sufficient with 25OHD at 73 nmol/L to 112 nmol/L (ref. 60-160 nmol/L) from 2016 through 2019. The patient was diagnosed with primary hypoparathyroidism and was treated with Alphacalcidol 0,5 μg × 1/daily, calcium 500 mg × 4 the first day followed by 400 mg × 2 and magnesium 360 mg × 3, which induced rapid clinical recovery with dissolvement of muscular pain and biochemical improvement. This case study suggests that further studies are needed to investigate the added value of routine monitoring for hypocalcemia as part of clinical follow-up of people living with HIV.
