Consensus-Based Recommendations for the Diagnosis, Treatment, and Monitoring of Hypoparathyroidism: Insights from the DACH Region

Year: 2025

Abstract: Hypoparathyroidism (HypoPT) is a rare endocrine disorder characterized by low parathyroid hormone (PTH) levels, hypocalcemia, hyperphosphatemia, reduced active vitamin D (1,25-OH2 vitamin D), and hypercalciuria. Due to its rarity, non-specialized physicians often lack experience managing HypoPT. To address this, expert consensus statements were developed for the DACH region (Germany, Austria, Switzerland), considering regional differences and high HypoPT incidence. These statements aim to enhance adherence to guideline recommendations and improve non-specialist knowledge. From December 2023 to April 2024, three rounds of a Delphi consensus survey were conducted with seven DACH-region clinical experts. Consensus was defined as agreement among at least 6 of 7 participants (85%). Experts agreed surgery accounts for 90% of chronic HypoPT cases. Common symptoms include paresthesia, muscle cramps, and fatigue. Albumin-adjusted serum calcium should be measured 12-24 h post-surgically, within 2 weeks, and every 3-6 months thereafter. Key treatment goals are maintaining albumin-adjusted serum calcium in the lower normal range, symptom control, and quality of life. Long-term objectives include avoiding hypo- and hypercalcemia phases and disease-related complications. Failure of calcium and active vitamin D therapy is defined by persistent symptoms, hospitalization, laboratory values outside of the normal range, or medication intolerance. Experts emphasized using HypoPT-specific, validated quality-of-life questionnaires. This consensus provides practical guidance for non-specialists in diagnosing, treating, and monitoring HypoPT, improving care in German-speaking regions.
