Swallowing problems in rheumatoid arthritis

Prediction of Dysphagia Severity and Diagnosis of Its Possible Causes in Rheumatoid Arthritis: A Cross-Sectional Study

Observational Tanta University · NCT07401732

This study will test whether a flexible fiberoptic throat exam can find joint-related swallowing problems and what predicts swallowing severity in adults with rheumatoid arthritis.

What this trial studies

This is a cross-sectional study of adult patients with rheumatoid arthritis seen at inpatient and outpatient clinics who meet the ACR/EULAR 2010 criteria. Participants will undergo a flexible fiberoptic pharyngolaryngoscopy (a bedside endoscopic throat exam) to document presence and severity of dysphagia. The study will analyze clinical and joint-related factors to identify predictors of swallowing severity and will note whether both oropharyngeal and esophageal dysphagia occur. Data will be collected during routine clinic visits without experimental treatments.

Who should consider this trial

Good fit: Adults over 18 with rheumatoid arthritis defined by the ACR/EULAR 2010 criteria who are alert and able to cooperate with a bedside throat endoscopy are the ideal candidates.

Not a fit: Patients with other clear causes of dysphagia (such as cancer, other rheumatologic diseases, jaw trauma, recent TMJ injections, congenital oral abnormalities), pregnancy, or those unable to cooperate or with anatomical barriers to nasofibroscopy are unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, the findings could help clinicians detect and address joint-related swallowing problems in RA earlier using a simple endoscopic exam.

How similar studies have performed: Flexible endoscopic swallowing exams are widely used to detect dysphagia in other conditions, but using them specifically to diagnose joint-affection-induced dysphagia in rheumatoid arthritis is relatively novel and not yet extensively validated.

Eligibility criteria

Inclusion Criteria:

* Patients with Rheumatoid arthritis defined by the American College of Rheumatology/European League Against Rheumatism collaborative initiative (ACR/EULAR) 2010 classification criteria.
* Patients aged above 18 years old, well-orientated, and cooperative.

Exclusion Criteria:

* concomitant cancer diagnosis, pregnancy.

* other rheumatologic conditions
* other comorbidities.
* other causes of TMJ arthritis, patients with TMJ, palatal or tongue congenital abnormalities, and patients who underwent TMJ injections in the last six months.
* Patients with any language disorders or intellectually handicapped (as certain questions depend on the patient's ability to comprehend and express their emotions regarding their issue) and patients with anatomical anomalies impeding the functionality of flexible nasofibroscopy.
