Sjögren‘S Syndrome

Abstract Sjogren’s syndrome (SS) is a complex, chronic, systemic, autoimmune disease that mainly affects the exocrine glands, especially the salivary and lacrimal glands, leading to the dryness of the mouth and eyes, along with fatigue, joint and muscle pain. The prevalence of SS is estimated to be between 0.05% and 1% in European population. Diagnosis of SS is based on the revised criteria of the American-European consensus group (AECG). Sjogren’s syndrome can be subclassified into primary disease (primary Sjogren syndrome, pSS) and a secondary disease (secondary Sjogren syndrome, sSS) when present with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and systemic sclerosis. The decrease in salivary flow and qualitative alterations in saliva could explain many of the oral manifestations frequently present in patients with SS. Low salivary flow may affect chewing, swallowing, speech and sleeping in pSS patients. Oral manifestations include dental erosion, dental caries, mucosal infection, ulcers and oral candidiasis. Recent studies reveal that pSS patients experience impaired olfactory and gustatory functions and have higher occurrence of oral complications such as dysgeusia, burning sensation in the tongue (BST) and halitosis. The exocrine manifestations and systemic involvement in SS significantly impact the patient’s perception of oral healthrelated quality of life (OHRQoL).

Sjögren‘S Syndrome

Background:Sjogren’s syndrome(pSS) is a chronic, progressive, and systematic autoimmune disease characterized by lymphocytic infiltration of exocrine glands 1 2. Sicca symptoms and abnormal fatigue are the main clinical presentation, but those symptoms are non-specific to patients, which lead to delayed diagnosis 1 3. The heterogeneous of clinical manifestation raise challenges regarding diagnosis and therapy in pSS, thus it’s necessary for us to sub-classify pSS.Objectives:To explore new biomarkers for diagnosis and subtypes of pSS based on Machine Learning Primary.Methods:All microarray raw datas (CEL files) were screened and downloaded from Gene Expression Omnibus (GEO). Meta-analysis to identify the consistent DEGs by MetaOmics. Weighted gene co-expression network analysis (WGCNA) was used to the modules related to SS for further analysis. Subclasses were computed using a consensus Non-negative Matrix Factorization (NMF) clustering method. Immune cell infiltration was used to evaluate the expression of immune cells and obtain various immune cell proportions from samples. P value < 0.05 were considered statistically significant. All the analyses were conducted under R environment (version 4.03).Results:A total of 3715 consistent DEGs were identified from the four datasets, including 1748 up-regulated and 1967 down-regulated genes. Tour meaningful modules, including yellow, turquoise, grey60 and bule, were identified (Figure 1A,1B). And 183 overlapping gene were screened from the DEGs and the Hub genes in the four modles for further analysis. We final divided pSS patients into three subtypes, of which yellow and turquoise in Sub1, grey60 in Sub2 and blue in Sub3. Sub1 and Sub3 were related to cell metabolism, while Sub2 had connection with virus infection (Figure 1C,1D). Infiltrated immune cells were also different among these three types (Figure 1E,1F).Conclusion:Patients with pSS could be classified into 3 subtypes, this classification might help for assessing prognosis and guiding precise treatment.References:[1]Ramos-Casals M, Brito-Zerón P, Sisó-Almirall A, et al.

Sjögren‘S Syndrome

Background:Sjogren’s syndrome (SS) is characterized by lymphocytic infiltration of the exocrine glands and marked B-lymphocytic cell hyperreactivity involving a variety of serum autoantibodies.1Salivary Gland Ultrasound (SGU) is a simple, fast, and well- tolerated examination, wich provides information about glandular structure and has proven to be very useful in the Sjögren Syndrome diagnosis2. A prognostic value has also been proposed due to its posible relationship with lymphomas and extra-glandular manifestations.Objectives:The objective of our study is to evaluate ultrasound results in patients who went through an SGU in clinical practice, its usefulness in the diagnosis of Sjögren’s syndrome and the presence of complications (lymphomas, extra-glandular manifestations or factors related to increased lymphoma risk).Methods:We conducted a retrospective cross-sectional study with review of clinical records that included all those patients coded as SGU in the Ultrasound unit of Rheumatology Department from 2016 to December 2019. Information collected included final diagnosis, laboratory results, clinical manifestations and ultrasound results. We performed an analysis on the frequency of pathological SGU and on the relationship between this lesions in patients with final SS diagnosis and the presence of lymphoma, extra-glandular manifestations and the laboratory values related with increased lymphoma risk (low complement levels, cryoglobulinemia, positive autoimmunity).Results:SGU was performed in 171 patients in four years, 162 women (94.7%). The previous diagnoses, reason for the request and final diagnosis are shown in Table 1. The vast majority of the SGU were normal, only 28 (16,3%) were pathological, 13 with a grade II and 8 with a grade III. In the other 7 patients grading was not available. Of the 28 patients with pathological SGU, none had lymphoma, only 3 had recurrent parotitis and 15 had had extra-glandular manifestations, mainly arthralgia / arthritis (12). Only 1 patient, with rheumatoid arthritis, had had a lymphoma and the SGU was normal. Antibody positivity was frequent in pathological SGU, 16/23 antinuclear antibodies, 13/22 anti-Ro and 9/23 rheumatoid factor. Of the 86 patients without previous diagnosis, 18 were diagnosed with Sjogren syndrome, 9 with pathological SGU and the rest were normal. No patient diagnosed with a dry non-autoimmune syndrome presented pathological SGU.Table 1.Previous diagnoses, reason for request and final diagnoses.Previous diagnoses (n: 171)Reason for request (n: 171)Final diagnosis (n: 78)Without prior diagnosis (n: 86)Dry non- autoinmune syndrome (n: 127)Dry non-autoimmune syndrome (n: 60)Primary Sjögren’s syndrome (n: 11)Primary Sjögren’s syndrome (n: 12)Primary Sjögren’s syndrome (n: 18)Systemic Lupus Erythematosus (n: 9)Lymphoma (n: 0)Secondary Sjögren’s syndrome (n: 0)Rheumatoid arthritis (n: 24)Control (n: 13)Other diagnoses (n: 7)Other diagnoses (n: 18)Other reasons (n: 11)Conclusion:The impact of the SGU is low and its use cannot, for now, displace other methods (e.g. salivary gland biopsy) in the diagnosis of SS. Also our low number of patients with pathological SGU together with the low prevalence of the complications studied (e.g. lymphomas = 1) prevents the expected comparisons.References:[1]Ramos-Casals M, Solans R, Rosas J, et al.

Sjögren‘S Syndrome

Management of Sjögren’s syndrome (SS) encompasses confirmation of diagnosis, disease assessment, and treatment of glandular and systemic manifestations including special situations such as pregnancy and SS-related lymphoma. The 2016 American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) classification criteria are the current gold standard for the diagnosis of SS. These criteria replace the 2002 American European Consensus Group (AECG) classification criteria. Salivary gland sialometry, sialochemistry, and ultrasound and tear osmolarity may be useful adjuncts. Symptoms of SS are non-specific and must be actively explored. When assessing patients with SS, it is important to consider not only objective parameters such as abnormalities in blood tests and changes in tear and salivary flow, but also patient-reported outcome measures and impact on quality of life. Current management of patients with SS is hampered by the lack of evidence-based strategies. The symptoms experienced by patients with SS are often not fully appreciated by clinicians, which may contribute to the suboptimal management of the condition. Management of fatigue remains a major challenge and a holistic, multidisciplinary approach is recommended. Factors that may contribute to fatigue should be fully addressed. Recent advances in the understanding of the pathogenic mechanisms of SS have informed more targeted therapeutic strategies with some promising data. Optimal management of SS requires expertise from different disciplines. Combined clinics with rheumatology, oral medicine, and ophthalmology input will improve care and communications as well as reduce the number of clinic visits for patients and healthcare-related cost. Effective link between pSS specialists, dentists, opticians, and general practitioners will facilitate early diagnosis and reduce risk of long-term disability of SS.

Management of Sjögren’s syndrome (SS) encompasses confirmation of diagnosis, disease assessment, and treatment of glandular and systemic manifestations including special situations such as pregnancy and SS-related lymphoma. The American European Consensus Group (AECG) classification criteria 2002 are the current gold standard for the diagnosis of SS. Salivary gland sialometry, sialochemistry, and ultrasound and tear osmolarity may be useful adjuncts. Recently, preliminary classification criteria of the American College of Rheumatology have been introduced as an alternative to the AECG criteria. Symptoms of SS are non-specific and must be actively explored. When assessing patients with SS, it is important to consider not only objective parameters such as abnormalities in blood tests and changes in tear and salivary flow, but also patient-reported outcome measures and impact on quality of life.

Sjögren‘S Syndrome

Patients with Sjögren's syndrome accumulated abnormal amounts of 99mtechnetium pertechnetate in the region of the nose during isotopic salivary flow studies. It was concurrently and independently observed that many patients with Sjögren's syndrome had hyposmia and pathological changes in the nasal mucous membranes. Fourteen patients with Sjögren's syndrome were studied for the relationship of the above observations and the nasal accumulation of radionuclide was compared with a control group of 16 subjects. Eleven of 14 patients with Sjögren's syndrome (78%) had nasal accumulation of the radionuclide; 14 had hyposmia and 13 of 14 had chronic inflammation of the nasal mucous membrane. One of 16 controls (6%) localized radionuclide in the nasal region. Results suggest that hyposmia, inflammatory changes in the nasal mucous membrane, and nasal accumulation of 99mtechnetium pertechnetate are interrelated aspects of Sjögren's syndrome.
