Abstract
Purpose: In patients with primary hyperparathyroidism (PHPT) and severe hypercalcemia, parathyroidectomy remains the only curative therapy. During the coronavirus disease 2019 (COVID-19) pandemic, when many hospital visits are suspended and surgeries cannot be performed, the management of these patients represents a challenging clinical situation. This article presents a literature review and discussion of the pharmacologic management of PHPT and severe hypercalcemia, which can be used as a temporary measure during the COVID-19 pandemic until parathyroidectomy can be performed safely.
Methods: This narrative review was conducted by searching literature on the PubMed, Medline, and Google Scholar databases using the terms primary hyperparathyroidism, hypercalcemia, cinacalcet, bisphosphonates, denosumab, vitamin D, raloxifene, hormone replacement therapy, coronavirus, and COVID-19.
Findings: Appropriate monitoring and remote medical follow-up of these patients are essential until the resolution of the pandemic. Cinacalcet is the drug of choice for controlling hypercalcemia, whereas bisphosphonate or denosumab is the drug for improving bone mineral density. Combined therapy with cinacalcet and bisphosphonates or cinacalcet and denosumab should be considered when the effects on serum calcium and bone mineral density are simultaneously desired.
Implications: Medical management of PHPT and severe hypercalcemia presents a reasonable alternative for parathyroid surgery during the COVID-19 outbreak and should be instituted until the pandemic ends and surgery can be performed safely. (C) 2021 Elsevier Inc.
