Aspects of xerostomia prevalence and treatment among rheumatic inpatients

Objectives. The aim of the study was to evaluate the prevalence of xerostomia among inpatients with rheumatic disorders at the Hospital of Kaunas University of Medicine (HKUM) and its association with age, sex, and xerophthalmia. Determining adequate treatment for xerostomia was also important, because untreated xerostomia may become aggravated and thus significantly impair patient’s quality of life. Material and methods. The authors designed a special questionnaire for conducting all studyrelated enquiries. Patients for this study were selected according to their case records ranging from 1998 to 2004. In total, there were 483 cases chosen based on prevalent rheumatic diseases, which were most conducive to xerostomia. Results. The results showed no significant evidence that the prevalence of xerostomia increased with age. Also, women were more susceptible to rheumatic diseases than men (W:M = 10:1) and are more likely to be affected by xerostomia and xerophthalmia (W:M = 2.5:1). A significant correlation was found between xerostomia and xerophthalmia. Only 17.7% of xerostomia-positive patients were treated for xerostomia, in comparison with xerophthalmia-positive patients who were treated for xerophthalmia in 84.8% of cases. It was shown that the modalities of treatment administered for xerostomia were neither sufficient nor up-to-date according to current recommendations found in medical literature. Conclusions. Xerostomia is closely correlated with xerophthalmia in rheumatic diseases. Xerostomia is more prevalent in older segments of population, especially in women, but we failed to prove statistical significance of older age in prevalence of sicca symptoms. Treatment administered to rheumatic patients for xerostomia in the HKUM is neither sufficient nor adequate

Xerostomia: clinic, etiology, diagnosis and treatment

The aim of this article is to review the problem of xerostomia considering its clinical, etiological, diagnostic and treatment features, basing on the today’s tutorials and scientific articles found in databases on the Internet. Recent epidemiologic data on the prevalence of xerostomia in different countries are introduced. There are analyzed the main aspects of clinical manifestations of xerostomia, according to the different etiology analyzed. The most common etiological factors causing xerostomia, especially the main three of them: radiation therapy, Sjögren’s syndrome, and drugs, are pointed out. The most popular and accepted clinical and laboratory assays for measuring and evaluating the function of salivary glands are represented. Attention is paid to xerostomia as substantiation of the separate diagnosis and its role in diagnosing other diseases. The concept of possible treatment modalities and prognosis are discussed. The main and most common problems concerning xerostomia are revealed

Microflora of the Oral Cavity in Patients with Xerostomia

Objective. The aim of this study was to evaluate the dependence of the condition of the microflora of the oral cavity on the etiology of xerostomia, patients’ sex, age, degree of hyposalivation, and duration of the sense of dryness. Material and Methods. A total of 64 patients with complaints of oral dryness referred to the Clinic of Oral and Dental Diseases, Hospital of Lithuanian University of Health Sciences, for consultation during the period from 2003 to 2005 were selected for the study. The etiological factors of xerostomia were as follows: radiotherapy (PRT) to the maxillofacial area, Sjögren’s syndrome (SS), and xerogenic medications, tricyclic antidepressants (TCAs). Results. There were 50 women and 14 men. Their mean age was 60.5±1.6 years. All the patients in the PRT group had high counts of Candida spp. as compared with percentages of patients in the TCA and SS groups (100% vs. 66.7% and 56.2%, P<0.05). Patients’ age and sex in different etiology groups had no significant impact on the condition of their oral microflora. There were equal percentages of patients with deficient and normal salivation in the TCA group (44% in both the groups; P<0.01). All the patients in the PRT group had pronounced hyposalivation (P<0.002). A significantly greater percentage of patients with severely reduced salivation had high counts of Lactobacillus spp. (P<0.01). Significantly greater percentages of patients with the clinical duration of xerostomia of up to 6 months had high counts of Lactobacillus spp. and Candida spp. colonies. Conclusions. In patients with xerostomia, the condition of the microflora of the oral cavity and impairment of major salivary gland function varied according to the etiology of the disease. The level of hyposalivation and the duration of xerostomia were found to have a significant impact on the microflora of the oral cavity
