About this study

Official title: Observational Cohort Study on Difference in Glucocorticoid-induced Adrenal Insufficiency in Patients With Rheumatoid Arthritis Related to Different Sensitivity Polymorphisms in the Glucocorticoid Receptor Gene

Development of glucocorticoid (GC)-induced adrenal insufficiency is a serious adverse effect of GC treatment. It is today not possible to predict this adverse effect. The project aims at investigating a possible individual aspect, which may render subjects more or less sensitive to glucocorticoids, and thereby influence development of GC induced adrenal insufficiency. The hypothesis is that subjects with one or another of the polymorphisms in the GC receptor gene will either have increased or diminished GC sensitivity. This may be responsible for differences in development of GC induced adrenal insufficiency.

Read the detailed description

Blood is sampled from patients with rheumatoid arthritis (RA), fulfilling the inclusion criteria and patients are genotyped for the SNPs N363S, BclI, ER22/23EK and 9β and grouped according to haplotypes. SNPs will be determined by polymerase chain reaction (PCR). Patients will be included for a Synacthen test, to evaluate their adrenal function. Information from the results of the study will be able to assist clinicians to identify patients at risk and thus individualize GC therapy in a tailored fashion. Results of the study will be important for all patient groups worldwide on GC therapy.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Synacthen testDiagnostic test

    250 microg Synacthen test, performed fasting, in the morning, starting between 08·00 and 10·30 h, after an overnight fast and a prednisolone pause of approximately 48 hours (depending on normal dose administration time).

Study groups in NCT01411046
Study groupRoleWhat they receive
RA treated with prednisolonePatients with RA treated with prednisolone, minimum 5 mg/day for minimum 6 months. Patients are grouped according to haplotype of 4 SNPs of the glucocorticoid recepror gene. Patients with or without these polymorphisms were invited to a Synacthen® test, but patients with a mixed hetero- and homozygote genotype were not. Adrenal function is evaluated with a Synacthen test.
Receives: Diagnostic Test: Synacthen test

What is being measured

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

  1. adrenal insufficiency

    test for adrenal function by stimulation test (Synacthen test)

    Measured: upon first visit within average 1 month

Secondary outcomes (4)
  1. quality of life

    test by questionnaires

    Measured: upon inclusion (baseline)

  2. Bone Density status

    DXA and bone markers

    Measured: results from latest DXA scan performed in routine settings, bonemarkers upon inclusion (baseline)

  3. body composition

    BMI, waist-, hip- circumferencia

    Measured: upon inclusion (baselline)

  4. metabolic syndrome

    blood lipids, abdominal obesity, blood pressure, fasting plasma glucose

    Measured: upon inclusion (baseline)

Questions about this trial

What is this clinical trial studying?

An observational study of Rheumatoid Arthritis, run by Copenhagen University Hospital, Rigshospitalet at 1 site in Denmark.

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 5 inclusion and 4 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: status not confirmed, as of the sponsor's last update on 28 Apr 2017. 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 Denmark. 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?

Results are not available in the source record.

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

Contact Ulla Feldt-Rasmussen, Professor (+45 35451023, ufeldt@rh.dk), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

adrenal insufficiency (time frame: upon first visit within average 1 month). 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 28 Apr 2017.
