Over the past few years, there have been significant advances in our understanding of hypoparathyroidism (HypoPT) in terms of its epidemiology, clinical presentation, etiology, and skeletal and renal complications. Moreover, the available treatment options for HypoPT have changed. This position statement of the Expert Group of the Polish Society of Endocrinology summarizes the current state of knowledge and provides recommendations for optimal management to assist clinicians in the diagnosis, treatment, and monitoring of HypoPT in Poland. The specific aspects of HypoPT management in children, pregnant and lactating women, and patients with chronic kidney disease are also discussed.

HypoPT is a rare disorder characterized by hypocalcemia and the lack or deficiency of parathyroid hormone (PTH). Hypoparathyroidism can be associated with complications, including nephrocalcinosis, nephrolithiasis, renal insufficiency, cataract, seizures, cardiac arrhythmia, depression, and an increased risk of infection. Minimizing complications of HypoPT requires careful evaluation and close monitoring of laboratory parameters. Conventional management of HypoPT has focused on maintaining serum calcium levels using oral calcium and active vitamin D. However, this approach is limited because it does not restore normal PTH function, is often associated with inadequate biochemical control, and raises concerns as to long-term side effects. HypoPT is the only classic endocrine insufficiency that is not commonly treated with the substitution of the missing hormone. Recently, recombinant human PTH(1-84) has become available, offering hope that the use of the missing hormone in the treatment of HypoPT will help achieve better control and reduce the risk of complications. However, this treatment is currently unavailable in Poland.
