Abstract
BACKGROUD Hypoparathyroidism (hypoPT) is characterized by acute and chronic complications due to insufficient parathyroid hormone (PTH) production or action. Several management guidelines have been developed, but mostly based on evidence from Western countries. Data from Eastern countries have not been systematically compared with those from Western countries. METHODS Literatures regarding to the epidemiology, genetics, risk factors, clinical manifestations and therapies for hypoPT in Easten and Western countries, including China, South Korea, Japan, India, and USA, Canada, Italy, and etc., were searched through PubMed and CNKI. This review was officially endorsed by European Calcified Tissue Society (ECTS) board. RESULTS Postoperative hypoPT is the major form of hypoPT in both Western and Eastern countries. The genetic profiles and clinical features of hypoPT are similar in Eastern and Western countries. The most commonly used medications in Eastern countries are calcium and native vitamin D or active vitamin D analogues, similar to their Western counterparts. While PTH replacement therapy is not available and approved to use in most Eastern countries. CONCLUSION Physicians and surgeons should follow the guidelines on the management of thyroid nodules, taking more care of protecting parathyroid glands during surgery. The cross-talk between East and West in the management of hypoPT should be continued. Direct comparisons of the management strategies in patients with hypoPT between Eastern and Wester countries regarding to the morbidity, mortality, quality of life, optimal dosage, efficacies and side-effects of conventional therapies or newer medications, as well as pharmacogenetics and pharmacoeconomics, would be valuable.

Abstract
Chronic hypoparathyroidism is characterized by low serum calcium, increased serum phosphorus, and inappropriately low or decreased serum parathyroid hormone. This rare disorder is associated with a variety of complications. The prevalence, incidence, mortality, financial burden, and epidemiology of complications of this disorder are not well understood. This narrative review summarizes current information on the epidemiology and complications of chronic hypoparathyroidism. The reported prevalence of chronic hypoparathyroidism ranges from 6.4-37/100,000, and the incidence is reported to be 0.8-2.3/100,000/year. Mortality is not increased in studies from Denmark or South Korea but was increased in studies from Scotland and Sweden. The financial burden of this disorder is substantial because of increased health care resource utilization in two studies but not well quantitated. Recognized complications include hypercalciuria, nephrocalcinosis, kidney stones, and chronic kidney disease; low bone turnover and possibly upper extremity fractures; cardiac and vascular calcifications; basal ganglia calcifications, cataracts, infections, neuropsychiatric complications, and difficulties with pregnancy. This review concludes that chronic hypoparathyroidism is a rare disorder associated with significant morbidity that may not increase overall mortality but is associated with a substantial financial burden. © 2022 The Authors.

Abstract
Parathyroid disorders are not as uncommon as once believed. Both hyper- and hypoparathyroidism are more prevalent in women, but for different reasons. The female preponderance seen in primary hyperparathyroidism may be pathogenically linked, as it is more common after menopause. By contrast, higher prevalence of hypoparathyroidism in women is related to thyroid surgery, which is performed more frequently in women; thus the female to male ratio of hyper- and hypoparathyroidism is about 3:1 and 4:1 respectively. For similar reasons, the mean age of patients with hypoparathyroidism, on average, is a decade lower than that of patients with primary hyperparathyroidism. Furthermore, primary hyperparathyroidism is the third most common endocrine disorder after diabetes and thyroid disorders, but the prevalence of hypoparathyroidism is about 34 fold lower than that of primary hyperparathyroidism. Current epidemiological data is reasonable for primary hyperparathyroidism, but inadequate for hypoparathyroidism. Further concerted efforts should be undertaken to better define the distribution, determinants and disease burden of both disorders in order to prioritize practice guidelines, disease management strategies, and research agendas.

Abstract
Until recently, very few studies have described the epidemiology of this rare disorder. Several large population-based studies have recently been published describing the prevalence and incidence of hypoparathyroidism in various countries. Some of these studies have described the epidemiology of both postsurgical and nonsurgical hypoparathyroidism. In addition, a number of studies have now been published describing the prevalence of complications of this disorder. This article summarizes the published medical literature regarding the prevalence and incidence of this disorder, and the risk of known complications of hypoparathyroidism.
