Abstract
Disruption of calcium homeostasis is a common complication in oncological patients, particularly in patients with metastatic bone disorder. Imbalance of bone metabolism may lead to hypercalcaemia or to less common hypocalcaemia.
The following article presents a case report of a patient with diagnosis of a lung cancer. Significant hypocalcaemia was detected at the time of hospital admission.
After initial intravenous mineral supplementation therapy, the deficiency of vitamin D was considered within the differential diagnosis of hypocalcaemia. Subsequent vitamin D metabolite blood test confirmed serious hypovitaminosis.
Based on the laboratory findings, mineral and vitamin D supplementations were adjusted during the hospitalization. The patient was referred to a hospice care.
In addition to the correct treatment of hypocalcaemia, this article also includes options of its sup- plementation, both parenteral and oral.
