Hypoparathyroidism: changes in brain structure, cognitive impairment, and reduced quality of life.

Hypoparathyroidism (HypoPT) is a disease with no/or inadequate production/secretion of parathyroid hormone (PTH) from the parathyroid glands. Low levels of PTH result in hypocalcemia, which is often treated with calcium supplementation and active vitamin-D analogs. However, increasing evidence suggests that HypoPT has a profound impact on several organ systems.

Fracture Risk in Patients with Hypoparathyroidism.

Purpose Of Review: To summarize the recently published scientific evidence on fracture risk in hypoparathyroidism.

Recent Findings: Hypoparathyroidism is characterized by a low bone turnover and a high bone mineral density. Data on fracture risk are sparse and due to the rarity of the disease, available studies have only been able to include relatively few patients.

Epidemiology and Financial Burden of Adult Chronic Hypoparathyroidism.

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.

Changes in treatment needs for chronic postoperative hypoparathyroidism during initiation of conventional treatment compared to stable phase of treatment.

Introduction: In our clinical experience, need for doses of active vitamin D and calcium supplements changes during the period following a diagnosis of postsurgical hypoparathyroidism (HypoPT), but only sparse data are available. In the present study, we aimed to investigate the magnitude of changes in need for activated vitamin D (alfacalcidol) and calcium supplements during initiation of therapy as well as time to be expected until a stable phase was achieved. Furthermore, we determined the frequency of (unexpected) episodes of hypo- and hypercalcaemia after reaching a steady state for alfacalcidol and calcium.

Determinants of hypercalciuria and renal calcifications in chronic hypoparathyroidism: A cross-sectional study.

Objective: Hypercalciuria, impaired kidney function and renal calcifications are common in chronic hypoparathyroidism (HypoPT). We aimed to study associations between indices of known importance to the kidney in HypoPT by hypothesizing adverse effects of hypercalciuria on renal outcomes.

Design: We used cross-sectional design.
