SHINE: Hypoparathyroidism Natural History
Study Details
Study Description
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.

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:
-
Build a prospective cohort of patients to study HPT-associated end-organ damage.
-
Determine end-organ physiologic consequences of HPT.
-
Elucidate determinants of HPT-associated end-organ damage.
Study Design
Outcome Measures
Primary Outcome Measures
- Kidney function [baseline, 6, 12, 18, 24, 30, 36 Months]
blood test for changes in eGFR (in mL/min/1.73m^2)
Secondary Outcome Measures
- Kidney calcification [Baseline and 36 Months]
Changes in kidney calcification and stones will be assessed by abdominal CT in an optional imaging sub group. Results will be assessed and reported by a clinician.
- Brain calcification [Baseline and 36 Months]
Changes in brain calcification will be assessed by head CT in an optional imaging sub-group. Results will be assessed and reported by a clinician.
- Vascular calcification [Baseline and 36 Months]
Changes in vascular calcification will be assessed by leg arterial calcifications on high resolution quantitative computed tomography in all, and aortic calcifications on abdominal CT and vertebral fracture assessment by DXA in optional imaging sub-group
- Bone mineral density [Baseline and 36 Months]
Changes in dual energy X-ray absorptiometry will be assessed in an optional imaging sub-group
- Bone microarchitecture and bone strength [Baseline and 36 Months]
Changes in high resolution peripheral quantitative computed tomography will be assessed
- Cardiac function [Baseline and 36 Months]
Changes in EKG will be assessed
- Transcriptomic signaling for calcification [Baseline and 36 Months]
Changes in microRNA will be assessed
- 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.
- Biomarkers urine [baseline, 6, 12, 18, 24, 30, 36 Months]
24 hour urine will be collected for changes in calcium, creatinine, total volume and protein
- 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
- Cognitive Function [baseline, 12, 24 and 36 Months]
Changes in cognitive function will be assessed by NIH Toolbox®; Letter Fluency by the Controlled Oral Word Association Test with the letters FAS; Sematic Fluency by Animal Fluency; List Learning and Memory by the Hopkins Verbal Learning Test; subjective cognitive function by FACT-Cog
- 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
- 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
- Sclerostin [Baseline and 36 months]
Will be obtained through blood collection and measured in pmol/L and changes will be tracked through visits
- FGF23 [Baseline and 36 months]
Will be obtained through blood collection and measured in pg/mL and changes will be tracked through visits
