    Abstract:
    Purpose: Previous studies have shown that haemodialysis (HD) patients frequently suffer from xerostomia. This problem is associated with difficulties in oral functions, increased risk of oral diseases and interdialytic weight gain (IDWG). The aims of this preliminary study are to evaluate the efficacy and safety of topical dry mouth products in treating xerostomia in HD patients and their impact in reducing IDWG. Materials and Methods: We included 25 HD patients that suffered from xerostomia and complied with inclusion criteria. Subjects received toothpaste, mouthwash and mouth gel for dry mouth. The duration of treatment was 4 weeks. Patients filled out a visual analogue scale (VAS) for xerostomia and Oral Heath Impact Profile (OHIP)-14 questionnaires. Clinical data and IDWG were collected of the medical history of HD patients. Questionnaires and IDWG were collected at baseline, 2 and 4 weeks post-treatment. Results: Twenty-five patients completed the study (56% male and 44% female). The mean age was 63.52 ± 12.50 years. The topical treatment statistically significantly (p = 0.0001) alleviated the symptoms of xerostomia and improved their quality of life (OHIP-14 scores) (p = 0.0001). We observed a statistically significantly IDWG (kg) and IDWG% reduction (p = 0.03) after the use of topical treatment for xerostomia. None of the patients reported side effects. Conclusions: Xerostomia might affect the quality of life and increase the IDWG of these patients. The daily use of topical treatment for xerostomia could decrease thirst and IDWG, improving the quality of life of HD patients. Future randomised studies are needed to confirm these results.
