Brief Summary:
This is a prospective, observational disease and drug registry designed to evaluate the safety and effectiveness profile of rhPTH(1-84) under conditions of routine clinical practice and to observe the clinical course of chronic hypoparathyrodism. No treatment is provided as a result of participating in this registry and all decisions on the participant's treatment are determined by his or her physician.

Group/Cohort Intervention/treatment
Chronic Hypoparathyroidism
A rare disease with a duration of longer than 6 months characterized by insufficient parathyroid hormone (PTH) secretion, which can result in hypocalcemia, hyperphosphatemia, and associated clinical findings.
Drug: Combination product (Natpara) and drug or supplements [Disease and drug registry]
Interventions evaluated are combination product (Natpara) and either drug or supplements (Calcium and vitamin D)

Primary Outcome Measures :
  1. Hypoparathyroidism Laboratory Test [ Time Frame: Baseline up to 10 years (follow-up) ]
    Hypoparathyroidism laboratory tests will be evaluated as change over time for 24-hour urine calcium, serum calcium, serum magnesium, serum phosphate and 25-OH vitamin D.

  2. Clinical Laboratory Test Results [ Time Frame: Baseline up to 10 years (follow-up) ]
    Results of laboratory tests collected per standard of care.

  3. Renal Function [ Time Frame: Baseline up to 10 years (follow-up) ]
    Renal function will be evaluated as change over time for serum creatinine, estimated glomerular filtration rate (eGFR; calculated), 24-hour urine calcium and 24 hour urine protein.

  4. Incidence Rate of the Renal Events [ Time Frame: Baseline up to 10 years (follow-up) ]
    Incidence rate of the renal events will be recorded for nephrolithiasis, nephrocalcinosis, hospitalization/emergency room visits for renal events.

  5. Incidence Rate of the Soft Tissue Calcifications (site) [ Time Frame: Baseline up to 10 years (follow-up) ]
    Incidence rate of the soft tissue calcifications (site) will be recorded.

  6. Incidence Rate of the Cataract [ Time Frame: Baseline up to 10 years (follow-up) ]
    Incidence rate of the cataract will be recorded by questionnaire (present/not present).

  7. Incidence Rate of the Bone Fractures (site) [ Time Frame: Baseline up to 10 years (follow-up) ]
    Incidence rate of the bone fractures (site) will be recorded.

  8. Incidence Rate of the Cardiovascular Events [ Time Frame: Baseline up to 10 years (follow-up) ]
    Incidence rate of the cardiovascular events will be calculated for this clinical outcome. Cardiovascular events include myocardial infarction, stroke, arrhythmia.

  9. Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) [ Time Frame: Baseline up to 10 years (follow-up) ]
    An adverse event (AE) is any noxious, pathologic, or unintended change in anatomical, physiologic, or metabolic function as indicated by physical signs, symptoms, or laboratory changes occurring in the registry, whether or not considered product-related. This includes an exacerbation of a pre - existing condition. An AE that meets one or m ore of the following criteria/outcomes is classified as SAE whether considered to be related to the pharmaceutical product or not: death, life-threatening, requires in patient hospitalization or prolongation of existing hospitalizations, a persistent or significant disability or incapacity, a congenital anomaly or birth defect and important medical events.

Secondary Outcome Measures :
  1. Health-related Quality of Life (HRQoL) [ Time Frame: Baseline up to 10 years (follow-up) ]
    Health-Related Quality of Life (HRQoL), as measured by the short-form-10 (SF-10) for pediatrics, short-form-36 (SF-36) for adults will be examined longitudinally using methods for continuous data.

  2. Disease-specific Patient-reported Outcome Measures [ Time Frame: Baseline up to 10 years (follow-up) ]
    Chronic hypoparathyroidism patient-reported outcome will be recorded as measured by the hypoparathyroidism multi-symptom diary (HPT-SD).

  3. Rate of Hospitalization/Emergency Room (ER) Visits [ Time Frame: Baseline up to 10 years (follow-up) ]
    The rate of hospitalizations and ER visits during follow-up will be summarized.

Ages Eligible for Study:   Child, Adult, Older Adult
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
This registry is designed to enroll globally at least 900 participants with chronic hypoparathyroidism, including a minimum of 300 participants who are receiving treatment with recombinant human parathyroid hormone, rhPTH (1-84) and a minimum of 600 participants who are receiving standard of care.

Inclusion Criteria:

1. Participants diagnosed with chronic hypoparathyroidism, ie, hypoparathyroidism with a duration of longer than 6 months, including:

  1. Adult participants (greater than or equal to [>=] 18 years of age) who are receiving for chronic hypoparathyroidism any of the following options: standard therapy, standard therapy plus rhPTH(1-84), or rhPTH(1-84) therapy alone.
  2. Pediatric participants (less than [<] 18 years of age) who are receiving for chronic hypoparathyroidism any of the following options: standard therapy, standard therapy plus rhPTH(1-84), or rhPTH(1-84) therapy alone.

Exclusion Criteria:

  1. Participants or legally acceptable representatives unable to provide informed consent.
  2. Participants using rhPTH(1-34) or used rhPTH(1-34) for more than 2 years and in the last 3 months.
  3. Participants currently enrolled in an interventional clinical study (whether or not the study is related to hypoparathyroidism). Note that this does not include participants enrolled in other observational registries.
  4. History of hypoparathyroidism resulting from a known activating mutation in the CaSR gene.
  5. History of hypoparathyroidism resulting from impaired responsiveness to PTH (pseudohypoparathyroidism).
