Objectives Primary Sjögren’s syndrome (pSS) is an autoimmune disease characterized by reduced lacrimal and salivary secretion. Sicca symptoms together with fatigue and musculoskeletal pain can significantly reduce the patients’ quality of life. Furthermore, low salivary secretion may disrupt the oral microbial homeostasis. The aim of this study was to compare the salivary microbiota from pSS patients with patients with sicca symptoms not fulfilling the classification criteria for pSS (non-SS), and with healthy controls without sicca complaints. Methods Pellets from centrifuged chewing-stimulated whole saliva from pSS patients (n = 15), non-SS sicca patients (n = 15) and healthy controls (n = 15) were prepared. DNA was extracted and analyzed by 16S rRNA gene sequencing. The acquired sequencing data were performed using the human oral microbiome database (HOMD). Results We detected 42, 45, and 34 bacterial genera in saliva samples from pSS patients, non-SS sicca patients, and healthy controls, respectively. The most abundant genera in all samples were Prevotella, Veillonella, Streptococcus, and Haemophilus. At species level Streptococcus intermedius, Prevotella intermedia, Fusobacterium nucleatum subsp. vincentii, Porphyromonas endodontalis, Prevotella nancensis, Tannerella spp., and Treponema spp. were detected in the samples from pSS and non-SS only, while Porphyromonas pasteri was mostly found among the healthy controls. Conclusion Our study indicated dysbiosis in the salivary microbiota from pSS and non-SS patients compared to healthy controls. Additionally, the results showed that the salivary microbiome in the pSS group differed significantly from the non-SS group.

A comprehensive evaluation of oral and ocular symptoms and findings in primary Sjögren’s syndrome (pSS) patients may provide valuable information for management. Medical history was obtained from female pSS patients, and sex- and age-matched non-SS patients with sicca symptoms (non-SS sicca controls) as well as healthy subjects without sicca complaints (healthy controls). Oral (Summated Xerostomia Inventory, SXI) and ocular (McMonnies Dry Eye questionnaire, MDEIS, and Ocular Surface Disease Index, OSDI) subjective complaints were recorded. Objective findings including clinical oral dryness scores (CODS), unstimulated and stimulated saliva secretion rates (UWS/SWS), Schirmer I test, tear osmolarity, tear film break-up time (TFBUT), and ocular surface staining (OSS) were determined. The pSS and non-SS sicca controls were extensively troubled by subjective dryness, while the pSS group had higher CODS, significantly lower saliva and tear secretion, shorter TFBUT and higher OSS than both control groups. Furthermore, candida counts were significantly higher in the pSS patients. In the pSS group, subjective oral dryness significantly correlated with ocular dryness (MDEIS: r = 0.5, OSDI: r = 0.413) and SWS was significantly correlated with Schirmer I (r = 0.419). The findings imply that interdisciplinary subjective and objective evaluation of patients with xerostomia and xerophthalmia not only have implications for patient care, but also may guide clinicians in differentiating between pSS and non-SS sicca patients.

Background There is a long-lasting need for non-invasive, more accurate diagnostic techniques when evaluating primary Sjögren’s syndrome (pSS) patients. Incorporation of additional diagnostics involving screening for disease-specific biomarkers in biological fluid is a promising concept that requires further investigation. In the current study we aimed to explore novel disease biomarkers in saliva and tears from pSS patients. Methods Liquid chromatography-mass spectrometry (LC-MS) was performed on stimulated whole saliva and tears from 27 pSS patients and 32 healthy controls, and salivary and tear proteomic biomarker profiles were generated. LC-MS was also combined with size exclusion chromatography to isolate extracellular vesicles (EVs) from both fluids. Nanoparticle tracking analysis was conducted on joint fractions from the saliva and tears to determine size distribution and concentration of EVs. Further EV characterisation was performed by immunoaffinity capture of CD9-positive EVs using magnetic beads, detected by flow cytometry. The LC-MS data were analysed for quantitative differences between patient and control groups using Scaffold, and the proteins were further analysed using the Database for Annotation, Visualization and Integrated Discovery (DAVID), for gene ontology overrepresentation, and the Search Tool for the Retrieval of Interacting Genes/Proteins for protein-protein interaction network analysis. Results Upregulation of proteins involved in innate immunity (LCN2), cell signalling (CALM) and wound repair (GRN and CALML5) were detected in saliva in pSS. Saliva EVs also displayed biomarkers critical for activation of the innate immune system (SIRPA and LSP1) and adipocyte differentiation (APMAP). Tear analysis indicated overexpression of proteins involved in TNF-α signalling (CPNE1) and B cell survival (PRDX3). Moreover, neutrophil gelatinase-associated lipocalin was upregulated in saliva and tears in pSS. Consistently, DAVID analysis demonstrated pathways of the adaptive immune response in saliva, of cellular component assembly for saliva EVs, and of metabolism and protein folding in tears in pSS patients. Conclusions LC-MS of saliva and tears from pSS patients, solely and in combination with size-exclusion chromatography allowed screening for possible novel biomarkers encompassing both salivary and lacrimal disease target organs. This approach could provide additional diagnostic accuracy in pSS, and could possibly also be applied for staging and monitoring the disease.

The aim of this study was to investigate the relationship between saliva secretion, halitosis and oral health-related quality of life (HRQoL). Informed consent was obtained from 65 participants including 24 patients with primary Sjögren’s Syndrome (pSS, 53±12y), 17 patients with dry eyes and dry mouth not fulfilling the classification for pSS (non-SS-sicca, 53±11y), and 24 healthy controls (49±11y). Unstimulated (UWS) and stimulated (SWS) whole saliva secretion rates were recorded as low (hyposalivation: SWS <0.7 ml/min, UWS <0.1 ml/min) or normal (SWS >0.7 ml/min, UWS >0.1 ml/min). Volatile sulfur compounds (VSC: hydrogen sulphide-H2S, methylmercaptan-CH3SH) in mouth air were measured by gas chromatography. HRQoL was assessed using the Oral Health Impact Profile-14 (OHIP-14). Mann-Whitney test was used in data analysis (p<0.05). In general, for UWS, subjects with hyposalivation had significantly higher mean CH3SH-levels than those with normal salivation (27.339.3 vs 9.913.6 ppb). For SWS, subjects with hyposalivation had significantly higher mean H2S-levels (184.5464.8 vs 43.964.1 ppb) and CH3SH-levels (27.237.4 vs 6.58.9 ppb). Within the non-SS patient group, those with hyposalivation had significantly higher H2S-levels than those with normal salivation. In general, there were no significant differences in OHIP-scores based on VSC levels. However, within the non-SS group, those with high H2S-levels (>112 ppb) reported significantly more often that they had “difficulties relaxing due to oral problems”, and that “life has been less satisfactory due to oral problems”, than those with low H2S-levels (<112 ppb). In conclusion, hyposalivation was generally associated with increased levels of oral VSC, indicating oral malodour. Surprisingly, patients with dry eyes and dry mouth who did not fulfill the classification for pSS seemed to be more affected in their daily life than patients who fulfilled the criteria.

This clinical study aims to assess some oral health parameters in patients diagnosed with primary Sjögren’s Syndrome (pSS), and is part of a larger project studying groups of patients suffering from dry mouth. Material and methods: Twenty female pSS patients (mean age 54±12.7y) and 32 healthy controls (mean age 50±12.4y), were recruited to the study and examined at a newly established Dry Mouth Clinic at the Faculty of Dentistry, University of Oslo, after giving written consent. A questionnaire was filled out and clinical and radiological examinations were performed. Differences between the patient and control groups were calculated using t-test or Chi-squared tests. Results: Approximately 1/3 of patients considered their general and oral health as ‘poor’ or ‘very poor’. No controls considered their general health as ‘poor’ or ‘very poor’, and only 1 control considered their oral health as ‘poor’ or ‘very poor’. Ninety percent of patients and 75% of controls had visited the dentist within the last year. There was no between-group difference in the mean number of teeth present (patients 25.5±2.7; controls 26.1±3.8). The patients had higher mean caries experience: DMFT (patients: 18.0±6.45; controls 12.9±7.26, p=0.014), FT (patients: 15.35±5.77; controls 11.28±6.10, p=0.02), and D3-5T (patients: 0.60±0.94; controls: 0.28±0.58, p=0.136). Visible plaque was observed in 30% of patients and 9.4% of controls (p=0.056). Signs of gingivitis were observed in 25% of patients and 6% of controls (p=0.054). Conclusion: Compared to controls, pSS patients reported poorer general and oral health. They had significantly higher dental caries experience, and a tendency to more plaque and gingivitis. However, the pSS patients reported visiting their dentist more regularly than the controls, suggesting an awareness of the oral consequences of reduced salivary function.
