Quality of Life Evaluation (SF-36) in Patients With Permanent Hypoparathyroidism After Total Thyroidectomy (Qol-Hypopara)

August 6, 2020 updated by: Nantes University Hospital

Quality of Life Evaluation (SF-36) in Patients With Permanent Hypoparathyroidism After Total Thyroidectomy

Persistent hypoparathyroidism is an underestimate but major complication of total thyroidectomy. The hypothesis of the investigators is that the mental health is impaired in hypoparathyroid patients compared with thyroidectomized patients without hypoparathyroidism. The investigators evaluated the quality of life using the SF-36 survey in comparison with a control population of patients thyroidectomized but free from this complication. The voice quality, the cardiovascular risk, the kidney function and the incidence of urinary lithiasis were also evaluated.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Persistent hypoparathyroidism is an underestimate but major complication of total thyroidectomy. In this retrospective, observational, multicentre study, the investigators evaluated the quality of life using the SF-36 survey in comparison with a control population of patients thyroidectomized but free from this complication. Patients in six centers in France (Angers, Le Mans, Limoges, Nancy, Nantes, la Pitié-Salpétrière) and in the association "Hypoparathyroïdisme France" were contacted by mail. The primary endpoint was the mental health. The physic and global quality of life scores were assessed as secondary endpoints. Medical and VHI surveys were also send to the patients. The voice quality, the cardiovascular risk, the kidney function and the incidence of urinary lithiasis were also evaluated.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Study Population

The study population is that of hypoparathyroid patients of the Hypoparathyroidism France combination who have undergone total thyroidectomy and who have agreed to participate in the study.

Patients with permanent hypoparathyroidism who were included in the ThyrQol study and in the FOTHYR study will also be solicited. Endocrinologists at the University Hospital of Nantes also have patients with permanent hypoparathyroidism in their patients.

The control population consists of patients who had a total thyroidectomy and were included in the ThyrQol study between 2014 and 2018, without sequelary hypoparathyroidism.

Description

Inclusion Criteria:

  • Patients operated of total thyroidectomy
  • Patients suffering from persistent hypoparathyroidism defined as serum PTH inferior to 15 pg/mL 6 months after the surgery, requiring vitamin-calcic supplementation.
  • Age superior to 18
  • Answering the survey

Exclusion Criteria:

  • Pregnancy at the time of the study
  • Age inferior to 18 or adult under guardianship
  • Patients with vitamino-calcic supplementation without serum PTH measurement
  • Cause of hypoparathyroidism other than post-operatory.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Mental health
Time Frame: Through study completion, an average of 1 year
Items from mental quality of life score defined by the SF36 (Short Form 36) survey
Through study completion, an average of 1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
