    Abstract:
    OBJECTIVES: Desiccation of the vocal tract can cause many voice problems. Therefore, we aimed to investigate whether patients with primary Sjögren's syndrome (pSS) with dry mouth have more voice-related problems than controls without the disease and to determine the factors affecting voice in pSS patients. METHODS: Patients with pSS and controls complaining of voice-related symptoms underwent acoustic analysis, aerodynamic study and stroboscopic analysis. They also completed the voice handicap index (VHI) questionnaire and perceptual voice analysis (GRBAS). Various disease-related parameters were obtained from pSS registry data. RESULTS: Fifty-five pSS patients and 52 controls were analysed. The subjects were all female, and mean age was 53.9 years. VHI score was significantly higher in the pSS patient group (median [interquartile range], 11 [3-30] vs. 5.5 [0- 15.75], p=0.014). However, the results of acoustic analysis aerodynamic study and stroboscopic findings were not different between the two groups. Disease-related parameters were available in 47 pSS patients. Correlation analysis revealed that jitter value positively correlated with ESSDAI (spearman's rho = 0.29, p=0.048) and patient global assessment (rho=0.3, p= 0.04). High VHI score was associated with low quality of life measured by EQ5D (rho=-0.493, p=0.0001). Of note, patients with longer disease duration (≥ 40 months) showed higher noise-to-harmonics ratio (NHR). CONCLUSIONS: Patients with pSS had higher VHI score, which was associated with low quality of life and longer disease duration was associated with increased noise in pSS patients. The likelihood of voice problems should be addressed with pSS patients, and vocal hygiene education will be important in those patients.
