Study summary

Long-term conventional treatment of chronic hypoparathyroidism does not fully restore calcium homeostasis leading to increased morbidity, emergency events and reduced subjective health status. To further investigate general morbidity, hypocalcemic events, subjective and daily life performance in patients with chronic hypoparathyroidism a disease specific questionnaire, as well as the SF-36 are handed out.

Read the detailed description

Design:

In a cross-sectional trial the subjective health status and burden of illness in patients with chronic hypoparathyroidism will be evaluated by using a disease specific questionnaire as well as the SF-36.

Patients:

Patients will be recruited out of the patient population of the participating five medical centers.

Statistical Analysis:

Documentation and analysis will be performed at the Department of Medicine I, Endocrine and Diabetes Unit, University of Würzburg, Germany. Data will be documented after pseudonymisation in a data base. For further analysis data will be compared to sex- and age-matched controls.

Inclusion criteria

  • chronic hypoparathyroidism (>12 months) under established therapy
  • chronic pseudohypoparathyroidism (>12 months) under established therapy
  • written

Exclusion criteria

Exclusion Criteria:

  • age \<18 years
  • no detailed documentation of hypo- or pseudohypoparathyroidism
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

    Time frame: 12 - 24 months

  2. Psychological disorders

    documentation of frequency of anxiety and depression under standard treatment

    Time frame: 12 - 24 months

  3. Subjective Health Status

    Assessment of the subjective health status due to chronic hypoparathyroidism by Assessment of subjective health status in patients with chronic hypoparathyroidism

    Time frame: 12-24 months

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 19, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
