About this study

Despite the strong association of hyperparathyroidism with arachidonic acid related lipid signals, little research has been performed over the years. A better understanding of the link between arachidonic acid remodeling, prostaglandin and endocannabinoid production with primary hyperparathyroidism in primary tissue/cells might open up new avenues for biomarker and thus to a potential therapeutic target.

Arachidonic acid remodeling might also have an impact on depression and elevated cytokines in patients with primary hyperparathyroidism. The investigators therefore will assess the correlation between postoperative improvement of PHQ-9 and cytokine levels with arachidonic acid remodeling.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Activity-based protein profiling (ABPP) will be used to assess the enzymes involved in calcium induced stress signals and endocannabinoid activation

    Measured: 2 months

Secondary outcomes (8)
  1. Measurement of the level of parathyroid hormone

    Measured: 2 months

  2. Measurement of the level of calcium

    Measured: 2 months

  3. Measurement of the level of cortisol

    Measured: 2 months

  4. Measurement of the level of 25-hydroxyvitamin D

    Measured: 2 months

  5. Measurement of the levels of the enzymes involved in the endocannabinoid system activation (diacylglycerol lipase; monoacylglycerol lipase, phospholipases, cyclooxygenases)

    Measured: 2 months

  6. Measurement of the level of endocannabinoids, arachidonic acid species, prostanoids and related anti-inflammatory lipids

    Measured: 2 months

  7. Measurement of the level of IL-6 and TNF-α

    Measured: 2 months

  8. Assessment of Patient Health Questionnaire - 9

    The Patient Health Questionnaire (PHQ-9) is described as a valid depression scale with good sensitivity and specificity for detecting depressive disorders, ranging from 1 to 27.

    Depression severity:

    1 to 4: minimal; 5 to 9: mild; 10 to 14: moderate; 15 to 19: moderately severe; 20 to 27: severe

    Measured: 2 months

Questions about this trial

What is this clinical trial studying?

An observational study of Primary Hyperparathyroidism, run by Insel Gruppe AG, University Hospital Bern at 1 site in Switzerland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Jan 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Activity-based protein profiling (ABPP) will be used to assess the enzymes involved in calcium induced stress signals and endocannabinoid activation (time frame: 2 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Jan 2023.
