Aim: To evaluate the larynx involvement in patients with rheumatoid arthritis (RA) in a clinical setting and correlate with the different clinical features related to more aggressive disease.
Methods: Cross-sectional study including 36 consecutive patients with RA. Reflux symptoms were evaluated by the Reflux Symptom Index (RSI) and vocal cord impairment by the Voice Handicap Index-10 (VHI-10). Laryngeal involvement was done by videolaryngostroboscopy (VLS).
Results: The mean age was 56,3 ± 14 years with a mean disease duration of 2,6 ± 3,1 years (range 0-16 years). Voice use was considered as professional users in 33%. Twenty-four (67%) out of 36 patients had abnormal findings of VLS. One patient had larynx nodules (bamboo nodules). Eleven patients (31%) were diagnosed with muscle tension dysphonia, and there were symptoms and signs of pharyngeal-laryngeal reflux in 23 (64%) patients. No signs of cricoarytenoid joint impairment was found.
Conclusions: Organic larynx involvement was uncommon in patients with RA. However symptoms and signs of pharyngeal-laryngeal reflux were seen in around 60% of patients. There was no correlation between the clinical phenotype, severity of disease, immunological profile or treatment with VLS findings.
