About this study

Chronic inflammatory rheumatisms (CIR) are a source of motor disability and various comorbidities, particularly cardiovascular and metabolic. They also significantly impact patients' quality of life, including sleep disturbances. Among CIRs, psoriatic arthritis is a chronic inflammatory arthropathy associated with psoriasis, typically seronegative for rheumatoid factor. This heterogeneous disease affects peripheral and/or axial joints and can include extra-articular manifestations such as uveitis and chronic inflammatory bowel diseases. Its prevalence is estimated between 0.3% and 1% in the general population.

SAPHO syndrome, similar to psoriatic arthritis, is characterized by specific bone involvement with a hypertrophic tendency, often affecting the axial skeleton and the anterior thoracic wall. Pain and inflammation are closely linked to sleep quality, creating a vicious cycle where pain disrupts sleep and poor sleep amplifies pain perception. Analgesic treatments, such as opioids, can also cause nocturnal respiratory pathologies, further disrupting sleep.

Inflammatory processes are regulated by sleep, influencing plasma concentrations of CRP, IL6, and TNF production. Patients with psoriatic arthritis or SAPHO syndrome share common risk factors with Obstructive Sleep Apnea Syndrome (OSAS), such as obesity, hypertension, and metabolic syndrome.

Sleep disorders are common in the general population and likely underdiagnosed in these patients. Several studies suggest a link between sleep disorders and these rheumatic conditions, affecting quality of life and exacerbating symptoms. Questionnaires like the Epworth and Pichot scales provide a more precise evaluation of these symptoms. However, objective sleep exploration through polysomnography has never been conducted in these patients.

In summary, CIRs, particularly psoriatic arthritis and SAPHO syndrome, significantly impact patients' quality of life and sleep, necessitating appropriate evaluation and management of associated sleep disorders.

Questions about this trial

What is this clinical trial studying?

An observational study of Psoriasis Arthritis and SAPHO Syndrome, run by Fondation Hôpital Saint-Joseph at 1 site in France.

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 6 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: looking for participants now, as of the sponsor's last update on 25 Jul 2025. 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 France. 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Juliette COURTIADE MAHLER (+33144127963, jcourtiade@ghpsj.Fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Type of sleep disorders (time frame: at 6months). 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 25 Jul 2025.
