Sažetak

Laboratory investigations of hypercalcemia involve testing of various biochemical parameters such as parathyroid hormone (PTH), 25-(OH) Vitamin
D (25-(OH) VitD), 1,25-(OH)2 Vitamin D3 (calcitriol) and PTH related peptide (PTHrp).
We herein present an atypical case of severe hypercalcemia in a patient with rheumatoid arthritis who has been treated for years by various biological
disease-modifying antirheumatic drugs (DMARDs) and suddenly presented with general state alteration, oedema and ulceration of her right
ankle.
We illustrate how tuberculosis (TB) can cause high calcitriol concentration and subsequently lead to potentially severe hypercalcemia. Moreover, we
highlight the importance of TB testing and follow-up in patients treated with biological DMARDs.
