Hypoparathyroidism Natural History
- Conditions
- Hypoparathyroidism
- Registration Number
- NCT05793853
- Lead Sponsor
- Columbia University
- Brief Summary
This is a prospective three year natural history study of adults with hypoparathyroidism. The goal is to monitor patients with hypoparathyroidism to define end-organ damage in the context of the disease.
Funding Source- FDA OOPD
- Detailed Description
The goal of this study is to prospectively collect data on the natural history of hypoparathyroidism (HPT). This will enable longitudinal data collection of complications in this disease, specifically defining the epidemiology of end-organ complications of HPT that are related to high calcification propensity. It will also determine relationships between calcification burden and end-organ disease severity and progression risk and assess the utility of traditional and novel biomarkers of mineral and bone metabolism on disease diagnosis and monitoring. These data will inform future investigations on the development, study, and implementation of HPT end-organ disease modifying strategies and impact clinical practice in hypoparathyroidism.The study objectives are to:
1. Build a prospective cohort of patients to study HPT-associated end-organ damage.
2. Determine end-organ physiologic consequences of HPT.
3. Elucidate determinants of HPT-associated end-organ damage.

- An understanding, ability and willingness to fully comply with study procedures and restrictions.
- Ability to voluntarily provide written, signed and dated informed consent as applicable to participate in the study.
- Male or female ≥18 years of age with HPT. All HPT sub-types are eligible, including surgical (HPT-S) and nonsurgical (HPT-NS) HPT: autoimmune, genetic (including but not limited to: DiGeorge syndrome, autoimmune polyendocrine syndrome type 1, hypoparathyroidism sensorineural deafness and renal disease syndrome, Kearns-Sayre syndrome, mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes [MELAS] syndrome, mitochondrial trifunctional protein [MTP] deficiency syndrome, Kenny-Caffey syndrome, Sanjad-Sakati syndrome, autosomal dominant hypocalcemia), infiltrative (granulomatous), mineral deposition (copper, iron), metastatic, radiation and idiopathic HPT.
- Diagnosis of HPT established based on historic hypocalcemia in the setting of inappropriately low serum PTH levels on two occasions.
- All treatment regimens are permitted, including but not limited to conventional management with calcium (e.g. calcium citrate, calcium carbonate, etc), active vitamin D (calcitriol, alfacalcidol), parent vitamin D, magnesium, phosphate binders and thiazides. Use of PTH-like drugs are permitted.

Transcriptomic signaling for calcification Baseline and 36 Months Changes in microRNA will be assessed
Dietary Intake baseline, 12, 24 and 36 Months Food frequency questionnaires will be administered to measure changes in calcium, phosphorus, vitamin D, and sodium intake
Quality of Life Through Self-Reported Questionnaires baseline, 12, 24 and 36 Months Quality of life will be assessed by SF-36, FACIT-IF (self-reported fatigue), PGI-S and PGI-I (patient global impression of severity and impact), Hospital Anxiety and Depression Scale (HADS) and the HPT Symptom Diary and changes will be tracked through visits
Calcioprotein Maturation Time Baseline and 36 months Will be obtained through blood collection and measured in minutes and changes will be tracked through visits
Biomarkers blood baseline, 6, 12, 18, 24, 30, 36 Months Changes in complete metabolic panel to see changes with eGFR (including albumin-corrected serum calcium), PTH, phosphorus, magnesium, 25(OH)D, 25(OH)D2, TSH, FT4.
Neurologic Tests of Motor Function baseline, 12, 24 and 36 Months Repeated Chair Stand (RCS) test will be administered to see how many times a patient can sit in and stand from a chair in 30 seconds and "Timed Up and Go" Test will measure how many seconds it takes for a patient to walk to assess changes in motor function
