32409518 | Impact of skin, musculoskeletal and psychosocial aspects on quality of life in psoriatic a | 2020 May | BACKGROUND: In psoriatic arthritis (PsA), both psoriasis and musculoskeletal manifestations may impair Health-Related Quality of Life (HRQoL). Our objective was to explore the impact of the various disease manifestations and disease consequences, including psychosocial factors, on HRQoL in PsA patients treated in the biologic treatment era. METHODS: Data collection in the 131 outpatient clinic PsA patients assessed included demographics, disease activity measures for both skin and musculoskeletal involvement and patient-reported outcome (PRO) measures, treatment and psychosocial burden. The skin dimension of quality of life was assessed by the Dermatology Life Quality Index (DLQI) and the overall HRQoL by the 15-Dimensional (15D) Questionnaire. RESULTS: The mean age was 51.9 years, PsA disease duration 8.6 years, 50.4% were men, 56.9% were employed/working and 47.7% had ≥1 comorbidities. Prevalence of monotherapy with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) was 36.6% and with biologic DMARDs 12.2% and combination of both 22.9%. Mean DLQI was 3.3 and 15D 0.84. In adjusted analysis, not employed/working, higher scores for fatigue, sleep disturbances, anxiety and depression, Modified Health Assessment Questionnaire and presence of comorbidities were independently associated with impaired HRQoL (lower 15D scores), whereas Psoriasis Area Severity Index (PASI) and DLQI were not. Younger age and higher Psoriatic Arthritis Disease Activity Score and PASI scores were independently associated with impaired skin quality of life (higher DLQI score). CONCLUSION: Our study highlights the negative impact the psychosocial burden, impaired physical function and comorbidities has on reduced HRQoL in PsA outpatients. Thus, to further improve HRQoL in PsA patients, not only physical concerns but also psychological concerns need to be addressed. | |
33039960 | Regulation of gut microbiota substantially contributes to the induction of intestinal Treg | 2020 Dec | Previously, we reported that oral administration of madecassoside, the main active triterpene in Centella asiatica L., exerted anti-arthritis effect by inducing the generation of regulatory T (Treg) cells in small intestine. This study investigates the action site and mechanism of madecassoside to induce Treg cells. In collagen-induced arthritis (CIA) of rats, oral administration of madecassoside significantly alleviated arthritis symptoms, but its main metabolite madecassic acid did not, suggesting that madecassoside functions in the parent form. Madecassoside was shown to increase the number of Treg cells and promote the expression of Foxp3 and IL-10 in rat ileum rather than duodenum and jejunum, as detected using the immunohistochemistry assay and quantitative PCR assay, respectively. Unexpectedly, madecassoside was absent of significant effect on in vitro Treg cell differentiation and the expression of Foxp3 and IL-10. A combined use of broad-spectrum antibiotics resulted in significant reduction of the anti-arthritis effect of madecassoside in CIA rats. The 16S rRNA gene sequence showed that madecassoside could reverse the changes of gut microbiota under arthritis condition, and enrich several bacteria such as Lachnospiraceae, Butyricicoccus, Faecalibacterium, Butyricicoccus pullicaecorum and so on. GC-MS assay showed that madecassoside elevated the levels of acetic acid and butyric acid, but not other short chain fatty acids (SCFAs) in the cecum contents of CIA rats. Butyric acid rather than acetic acid could induce the in vitro differentiation of Treg cells and the expression of Foxp3 and IL-10. Accordingly, when madecassoside was co-administered with heptanoyl CoA, the competitive inhibitor of butyrate synthase, its effect on butyric acid production, Treg cell proportion and arthritis nearly disappeared. These findings indicate that oral madecassoside induces the generation of Treg cells and therefore displays anti-arthritis effect in the parent form but not metabolites, and the ileum is the main action site. The mechanism of madecassoside can be summarized as: expansion of the richness of butyrate-producing bacteria-up-regulation of intestinal butyrate level-induction of Treg cell differentiation and IL-10 expression. | |
32304993 | CXCR3 antagonist AMG487 inhibits glucocorticoid-induced tumor necrosis factor-receptor-rel | 2020 Jul | Rheumatoid arthritis (RA) is an autoimmune disease classified by uncontrolled joint inflammation leading to the destruction of both cartilage and joints. Despite progress made in RA treatment in the past decade, new drugs with high efficacy and fewer long-term adverse effects are still needed; thus, safe anti-inflammatory therapies for RA are urgently needed. Previous results demonstrated that the CXCR3 antagonist is an extremely attractive therapeutic target for the treatment of several autoimmune diseases, suggesting that it might have an inhibitory effect on RA. In this study, we investigated the effect of AMG487, a selective CXCR3 antagonist, on collagen-induced arthritis (CIA) in mice and evaluated its potential therapeutic mechanism.Following induction of CIA, mice were treated with AMG487 (5 mg/kg, intraperitoneally), to investigate their protective effects against CIA. CD4, CD25, CCR6, IL-9, NF-κB, IL-6, IL-17A, IL-21, STAT6 and Foxp3 expressing GITR(+) and CD45(+) cells were measured in the spleen using flow cytometry to assess anti-inflammatory effects of AMG487. The mRNA and protein expression of GITR, CCR6, IL-9, and IL-21 were measured using quantitative real-time PCR and western blot analysis in knee tissue. AMG487 significantly alleviated joint inflammation by decreasing GITR(+)CD25(+), GITR(+)CD45(+), GITR(+)IL-9(+), GITR(+)NF-κB(+) CD45(+)CD4(+), CD45(+)CCR6(+), CD45(+)IL-6(+) cells, CD45(+)IL-17A(+), and CD45(+)IL-21(+), and increasing GITR(+)Foxp3(+) and GITR(+)STAT6(+) cells. There was a significant decrease in mRNA and protein expression of GITR, CD4, CCR6, IL-6, IL-9, and IL-21 in knee tissue of CIA mice. This study demonstrates that AMG487 has a potential therapeutic effect on RA and could explore novel anti-inflammatory therapies for its treatment. | |
33081201 | Arthralgia Induced by BRAF Inhibitor Therapy in Melanoma Patients. | 2020 Oct 16 | INTRODUCTION: BRAF inhibitors (BRAFi), commonly used in BRAF-mutated metastatic melanoma (MM) treatment, frequently cause arthralgia. Although this is one of the most common side effects, it has not been characterized yet. METHODS: We retrospectively included all patients treated with BRAFi +/- MEK inhibitors (MEKi) for MM at the National Center for Tumor Diseases (Heidelberg) between 2010 and 2018 and reviewed patient charts for the occurrence and management of arthralgia. The evaluation was supplemented by an analysis of frozen sera. RESULTS: We included 154 patients (63% males); 31% (48/154) of them reported arthralgia with a median onset of 21 days after the start of the therapy. Arthralgia mostly affected small joints (27/36, 75%) and less frequently large joints (19/36, 53%). The most commonly affected joints were in fingers (19/36, 53%), wrists (16/36, 44%), and knees (12/36, 33%). In 67% (24/36) of the patients, arthralgia occurred with a symmetrical polyarthritis, mainly of small joints, resembling the pattern typically observed in patients affected by rheumatoid arthritis (RA), for which a role of the MAPK signaling pathway was previously described. Patients were negative for antinuclear antibodies, anti-citrullinated protein antibodies, and rheumatoid factor; arthritis was visible in 10 of 13 available PET-CT scans. The development of arthralgia was linked to better progression-free survival and overall survival. CONCLUSION: Arthralgia is a common side effect in patients receiving BRAFi +/- MEKi therapy and often presents a clinical pattern similar to that observed in RA patients. Its occurrence was associated with longer-lasting tumor control. | |
33132443 | Aseptic meningitis as an initial presentation of Sjögren syndrome: a report of two cases | 2020 Aug | Sjögren syndrome (SS) is one of several collagen vascular diseases that occasionally involve the central nervous system. We report two cases of SS involving young patients who initially presented with aseptic meningitis. A male with recurrent AM was found to have anti-Ro/SSA and La/SSB antibodies in a screening test for autoimmune process. A minor salivary gland biopsy revealed lymphocytic infiltrations compatible with SS, although the patient did not exhibit sicca symptoms. A female presenting with AM and polyarthritis also reported xerophthalmia. Anti-Ro/SSA antibody testing and a positive result in a minor salivary gland biopsy led to the diagnosis of SS. In the literature review, we found that AM or aseptic meningoencephalitis (AME) preceded or had a concomitant onset with SS in approximately 70% of cases. Screening for anti-Ro/SSA antibody, as well as systemic assessment for rheumatic symptoms, may be useful for diagnosing AM/AME of unknown etiology. | |
31919014 | Cell-autonomous epithelial activation of AIM2 (absent in melanoma-2) inflammasome by cytop | 2020 Mar | Primary Sjögren's syndrome (SS) is characterized by chronic periductal inflammatory infiltrates in the salivary glands. Several previous studies have indicated that the ductal epithelia of SS patients play a pro-inflammatory role and manifest an intrinsically activated status, as demonstrated in cultured non-neoplastic ductal salivary gland epithelial cell (SGEC) lines. Herein, we investigated the activation of inflammasomes in the salivary epithelia of SS patients and non-SS controls, using salivary biopsy tissues and SGEC lines. The ductal epithelial cells of SS patients were found to display significant activation of the AIM2 (absent in melanoma-2) inflammasome. Such activation occurred in a cell-autonomous manner, as it was illustrated by the constitutively high expression of AIM2 activation-related genes, the presence of cytoplasmic ASC specks and the increased spontaneous IL-1β production observed in patients' SGEC lines. Since AIM2 activation is known to occur in response to cytoplasmic DNA, we further searched for the presence of undegraded extranuclear DNA in the SGEC lines and SG tissues of patients and controls. This investigation revealed marked cytoplasmic accumulations of damaged genomic DNA that co-localized with AIM2 in the specimens of SS patients (but not controls). The SGEC lines and the ductal tissues of SS patients were also found to manifest impaired DNase1 expression and activity, which possibly denotes defective cytoplasmic DNA degradation in patients' cells and AIM2 triggering thereof. In corroboration, DNase1-silencing in normal SGEC was shown to lead to high AIM2-related gene expression and IL-1β production. Our findings indicate that the cell-intrinsic activation status of ductal epithelia in SS patients owes to persistent epithelial AIM2 activation by aberrant cytoplasmic DNA build-up. | |
33331314 | [Investigation of sleep disturbance and related factors in patients with primary Sjögren' | 2020 Dec 18 | OBJECTIVE: To investigate the prevalence of sleep disorders and the relevant determinants in a cohort of primary Sjögren' s syndrome (pSS) patients. METHODS: One hundred and eighty-six pSS patients were included in the study, who were admitted to Peking University People' s Hospital and met the criteria of inclusion and exclusion. Sleep quality was assessed using the Pittsburgh sleep quality index(PSQI).Depression, anxiety were evaluated by patient health questionnaire (PHQ)-9, generalized anxiety disorder(GAD)-7, respectively. The demographic and clinical data were also recorded.Disease activity and damage were evaluated with the European League Against Rheumatism Sjögren's syndrome disease activity index (ESSDAI). According to the PSQI score>7, the pSS patients were divided into 152 cases of sleep disorder group and 34 cases of normal sleep group. Mann-Whitney U test, Chi-square test or Fisher' s exact test, independent samples t test, Spearman correlation analysis and Logistic regression were used for statistical analysis. RESULTS: The prevalence of sleep disturbance (PSQI > 7) was 81.7% (152 / 186) in the pSS patients, and 52.7% (98/186) had moderate or severe sleep disorders (PSQI≥ 11). The mean PSQI score of sleep disordered group was (12.29±3.30), while the normal sleep group PSQI score was (5.50±1.20). The PSQI score, PHQ-9 score and GAD-7 score in the sleep-disordered group were significantly higher than those in the normal sleep group (P=0.000, 0.035, 0.031). The PSQI score in the sleep disordered group were significantly higher than those in the normal sleep group in seven aspects: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disorders, hypnotic drug use and daytime dysfunction. All of them had statistical significance. According to the results of Spearman correlation analysis, PSQI had significantly positive correlation with course of disease, anxiety, depression score (r=0.151, 0.240, 0.421, P < 0.05), but negatively correlated with C3, C4 (r=-0.021, -0.235, P < 0.05). Logistic analysis identified the course of disease(OR=2.809, 95%CI: 1.21-6.52)and PHQ-9 score(OR=1.422, 95%CI: 1.04-1.94)as predictors of sleep disorders. CONCLUSION: The incidence of sleep disorder in the pSS patients was higher, which was closely related to the course of disease, anxiety, depression and other factors. It is critical to assess and manage comprehensively the disease. | |
33316834 | A Presentation of Pediatric Sjögren's Syndrome with Abducens Nerve Palsy. | 2021 Oct | Sjögren's syndrome is a systemic autoimmune disease that classically presents with xerophthalmia and xerostomia. However, neurological manifestations occur in 10 to 60% of patients with Sjögren's syndrome and can often precede classic sicca symptoms in Sjögren's syndrome in some cases up to several years. Rarely, cranial neuropathy can be the initial presentation. Here, we present the first case of a 15-year-old girl with left abducens palsy in the setting of a new diagnosis of Sjögren's syndrome. Comprehensive evaluation revealed elevated Sjögren's syndrome-related antigen A-60 antibody. Cerebrospinal fluid analysis was unremarkable. Radiological studies demonstrated evidence of chronic parotitis. Acute treatment included high-dose methylprednisolone and rituximab, and symptoms resolved by follow-up at 2 weeks. The most common neurological disorder of Sjögren's syndrome is pure sensory neuropathy. In pediatric Sjögren's syndrome, neurological complications are rare but include aseptic meningoencephalitis, acute disseminated encephalomyelitis, transverse myelitis, optic neuritis, and cranial neuropathies. In the circumstance of a cranial neuropathy, the trigeminal nerve is most commonly involved but oculomotor nerves can occasionally be affected. Abducens palsies have been described in four patients with Sjögren's syndrome, typically women and all middle aged or older, with our patient being the first pediatric case. Thus, it is important to consider screening for Sjögren's syndrome in the evaluation of pediatric patients with new onset of isolated cranial neuropathy even in the absence of classic sicca symptoms. | |
33278589 | High prevalence of salivary gland ultrasound abnormalities in systemic sclerosis. | 2021 Mar | OBJECTIVE: To evaluate salivary gland (SG) involvement in patients with systemic sclerosis (SSc) using SG ultrasound (SGUS). METHODS: Patients with SSc (n=62), primary Sjögren's syndrome (pSS) (n=59), and idiopathic Sicca syndrome (n=43) were evaluated using the outcome measures in rheumatology clinical trial (OMERACT) definitions of the SGUS scoring system. The hyperechogenic bands using the 0-3 scoring system, intraglandular power Doppler signal (PDS), and SG volumes were also assessed. RESULTS: The proportion of patients with OMERACT grades (≥2) among the four SGs was significantly higher in SSc (51.6%) and pSS (62.7%) groups than those in the idiopathic Sicca syndrome group (4.7%). Patients with SSc and pSS had significantly higher total fibrosis grades than controls. No difference in fibrosis grades was observed between SSc and pSS groups. The PDS scores of SGs were higher in the SSc group than in the idiopathic Sicca syndrome group. SG volumes did not differ between the groups. SSc patients with SGUS grades ≥2 had more anti-centromere antibodies (ACA) (65.6% vs. 30.0%) than individuals with grades 0-1. SSc patients with fibrosis grades ≥2 reported more Sicca symptoms than those with grades 0-1. Inhomogeneity and hyperechogenic bands within the SGs were not associated with organ involvement in SSc. CONCLUSIONS: More than half of patients with SSc, specifically with ACA, showed SG involvement. SG fibrosis was more prominent in SSc than in idiopathic Sicca syndrome and was associated with subjective Sicca symptoms. However, hyperechoic bands within the SGs are not features that can differentiate between SSc and pSS. | |
32616590 | Pulmonary arterial hypertension associated with primary Sjögren's syndrome: a multicentre | 2020 Nov | OBJECTIVES: Primary Sjögren's syndrome (pSS) is an important cause of pulmonary arterial hypertension (PAH), which remains insufficiently studied and needs attention. This study aimed to investigate the clinical characteristics, risk factors, prognosis and risk assessment of pSS-PAH. METHODS: We established a multicentre cohort of pSS-PAH diagnosed by right heart catheterisation. The case-control study was conducted with pSS-non-PAH patients as a control group to identify the risk factors for PAH. In the cohort study, survival was calculated, and risk assessment was performed at both baseline and follow-up visits. RESULTS: In total, 103 patients with pSS-PAH were enrolled, with 526 pSS-non-PAH patients as controls. The presence of anti-SSB (p<0.001, OR 4.095) and anti-U1RNP antibodies (p<0.001, OR 29.518), the age of pSS onset (p<0.001, OR 0.651) and the positivity of corneal staining (p=0.003, OR 0.409) were identified as independent risk factors for PAH. The 1-, 3- and 5-year survival rates were 94.0%, 88.8% and 79.0%, respectively. Cardiac index (p=0.010, hazard ratio (HR) 0.161), pulmonary vascular resistance (p=0.016, HR 1.105) and Sjögren's syndrome disease damage index (p=0.006, HR 1.570) were identified as potential predictors of death in pSS-PAH. Long-term outcomes were improved in patients in the low-risk category at baseline (p=0.002) and follow-up (p<0.0001). CONCLUSION: The routine screening of PAH is suggested in pSS patients with early onset and positivity for anti-SSB or anti-U1RNP antibodies. Patient prognosis might be improved by improving reserved cardiopulmonary function, by achieving a damage-free state and especially by achieving low-risk category, which supports the treat-to-target strategy for pSS-PAH. | |
32631601 | Sjögren Syndrome and Cancer. | 2020 Aug | The association between malignancy and rheumatic diseases has been demonstrated in a multitude of studies. Little is understood regarding the pathogenesis of rheumatic and musculoskeletal diseases in association with malignancy. There is strong evidence regarding the association between Sjögren syndrome and lymphoma as well as risk factors for development of lymphoma in these patients. This article discusses the accumulating data on various malignancies described in primary Sjögren syndrome, highlighting non-Hodgkin lymphoma and thyroid, multiple myeloma, and skin cancers. These reported associations may have clinical implications in daily practice and contribute to understanding of both autoimmunity and cancer. | |
31880282 | Oral lesions in patients with primary Sjögren's syndrome. A case-control cross-sectional | 2020 Jan 1 | BACKGROUND: To evaluate the presence of oral lesions in a group of patients with primary Sjögren's syndrome (pSS) and compare these results with a matched control group (CG). MATERIAL AND METHODS: An observational cross-sectional study was conducted. 61 pSS patients (60 women, 1 man, mean age 57.64±13.52) diagnosed according to the American European Criteria (2002), and 122 matched control patients (120 women, 2 men, mean age 60.02±13.13) were included. Demographic and medical data, oral lesions and salivary flow rate were collected. RESULTS: Compared with the controls, pSS patients were 3.95 more likely to have oral lesions (OR 3.95; 95% CI 2.06-7.58; p=0.0001). 57.4% pSS patients presented oral lesions compared to 25.4% in CG. The most common were candidiasis (13.1% vs 2.5%), traumatic lesions (13.1% vs 4.1%), apthae (8.2% vs 0), and fissuration of the tongue (8.2% vs 0.8%). pSS patients with oral lesions had lower salivary flow levels (stimulated and unstimulated), although these differences were not significant. Significant associations were found between the presence of oral lesions and systemic manifestations and history of parotid gland enlargement in pSS patients. CONCLUSION: pSS patients suffer more oral lesions than general population and these lesions may aggravate the pSS disease. | |
32031309 | Sialographic analysis of parotid ductal abnormalities associated with Sjogren's syndrome. | 2020 Jul | OBJECTIVES: To analyze the location and degree of parotid ductal abnormalities associated with Sjogren's syndrome (SS) and to correlate findings with the duration of the disease. To develop a classification system based on contemporary sialography techniques and employ the system to grade findings on sialograms. To assess the role for therapeutic intervention in patients with SS. METHODS: Retrospective chart review of a consecutive series of 337 sialograms done by the senior investigator over a 10-year period identified 26 sialograms in patients who met the criteria for SS as defined by the American-European Consensus Group (2002). A classification system was developed to grade the degree of ductal abnormalities identified on the sialograms. Individual, initial blinded review of these sialograms was performed by two head and neck radiologists to identify and grade abnormalities. Radiographic findings were correlated with patient history including symptom duration. RESULTS: All patients with SS had stenoses within the ductal system. About 73.1% of patients had stenoses in each branch of the ductal system (primary, secondary, and tertiary ducts). In 19% of patients, the main duct was of normal caliber despite the presence of stenosis in the more proximal ducts (secondary and tertiary ducts). Peripheral (proximal) duct dilation was characterized among those affected in patterns classified as destructive (34.6%), cavitary (26.9%), globular (11.5%), or punctate (11.5%). A statistically significant positive correlation (p = .0360) was identified between symptom duration and degree of main ductal stenosis. CONCLUSION: Sialography may be useful to objectively assess the degree of parotid ductal damage in SS employing a newly proposed classification system. This assessment may assist clinicians in tailoring management to selectively include ductal dilation. | |
31058469 | Meta-Analysis of Treatment for Primary Sjögren's Syndrome. | 2020 Jul | OBJECTIVE: The current focus of treatment in primary Sjögren's syndrome (SS) is symptom management. Since SS is an autoimmune disease with multisystem involvement, systemic immunosuppression may have a role in improving signs and symptoms and preventing progression. We undertook this review to assess the efficacy and safety of immunomodulation on primary SS from randomized clinical trials (RCTs). METHODS: Five electronic databases (Medline, Embase, Central, ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry Platform) were searched to include RCTs for the treatment of SS. Primary outcome measures included ocular dryness, oral dryness, tear production, and salivary function. Serious adverse events (AEs) and withdrawals due to AEs were also assessed. RESULTS: The search yielded 32 trials evaluating 19 different medications. The average duration of diagnosis was long (up to 9.2 years). Twenty-two trials examined ocular and oral dryness, for which only 2 and 4 trials showed statistically significant improvements, respectively. No studies found a benefit for tear production; few studies found improvements for unstimulated salivary flow (3 of 16 RCTs) and stimulated salivary flow (2 of 14 RCTs). Meta-analysis at 6 months found improvements as compared to placebo for unstimulated salivary flow (P = 0.003) and a decrease in the erythrocyte sedimentation rate (P = 0.007). No differences were seen for serious AEs, but there were increased withdrawals from AEs (risk ratio 2.33; P = 0.03). CONCLUSION: Reducing inflammation potentially improves salivary gland function. No individual immunomodulatory drug demonstrated a consistent benefit in xerostomia and xerophthalmia. Further work is needed to identify SS patients with an ability to improve and with outcomes that are valid and sensitive to change within clinical trials. Tradeoffs in the future between benefit and safety may also be important, because more withdrawals occurred with active treatment. | |
33145631 | Sjögren syndrome associated with protein-losing enteropathy: case-based review. | 2021 Jun | The association between Sjögren's syndrome (SS) and protein-losing enteropathy (PLE) was scarcly reported. To analyze the clinical, therapeutic, and outcome characteristics of patients with SS and PLE and also to delineate the potential mechanisms and pathways connecting the gut to SS targeted organ's pathology. Systematic screening was conducted using PubMed/MEDLINE, LILACS, SciELO, Web of Science, and Cochrane, dating 1980 to 2020. SS and PLE were the key words. Eighteen patients with SS and PLE were summarized. The patient's ages ranged between 20 and 88 years, and only 4 were males. Primary SS was observed in most cases. Anti-Ro was detected in 100% of the cases while anti-La was reported in 64% of them. The clinical manifestations were protein loss, edema of the lower limbs, pleural effusion, ascites, facial edema, anasarca, diarrhea, and weight loss. Among these clinical manifestations, edema of the lower limbs was the most severe. Albumin concentration was 0.9-3.4 g/dL which increased to 2.8-4.3 g/dL after treatment. Small bowel biopsy was performed in all of the cases. Concerning the therapy, all the patients received systemic glucocorticoids. All of them improved. The period of onset of improvement ranged from 3 weeks to 36 months (an average of 3 months). The early diagnosis and appropriate therapy of PLE in patients with anti-Ro positive SS and who present edema, anasarca, or hypoalbuminemia is vital for a beneficial outcome. An excellent clinical improvement in all the cases was observed when treated early enough by cortico-therapy, thus preventing patient's deterioration, complications, and reducing morbidity and potential mortality. | |
32934134 | Salivary Gland Focus Score Is Associated With Myocardial Fibrosis in Primary Sjögren Synd | 2021 Jun | OBJECTIVE: The risk of clinically manifested major cardiovascular (CV) events in primary Sjögren syndrome (pSS) remains unclear. This study aimed to assess myocardial fibrosis in pSS and investigate the associated disease characteristics by cardiac magnetic resonance imaging (cMRI). METHODS: We performed a cross-sectional study of patients with pSS without cardiac symptoms. Labial gland biopsy was documented in 44 patients (85%). Patients without CV risk factors underwent contrast-enhanced cMRI. Late gadolinium enhancement (LGE) was used to assess myocardial fibrosis. Myocardial edema was assessed using T2-weighted imaging (T2WI). We compared the left ventricular (LV) geometry and function between the groups with and without LGE. Further, we explored the associations of cMRI abnormalities with pSS characteristics. RESULTS: Fifty-two women with pSS (median age 55, IQR 47.0-65.7 yrs) were enrolled in the study. LGE was observed in 10 patients (19%), two of whom showed high intensity on T2WI. High intensity on T2WI was observed in 3 patients (5.8%). LV mass index and LV mass/end-diastolic volume tended to be higher in the LGE-positive group than in the LGE-negative group (P = 0.078 and 0.093, respectively). Salivary gland focus score (FS) ≥ 3 was independently associated with LGE-positive in the multivariable analysis (OR 11.21, 95% CI 1.18-106.80). CONCLUSION: Subclinical myocardial fibrosis, as detected by cMRI, was frequent in patients with pSS without cardiac symptoms. Abnormal cMRI findings were associated with salivary gland FS ≥ 3. | |
32780886 | Does Nasal Secretion Decrease in Sjögren Syndrome and Does This Affect Nasal Function? | 2021 Feb | OBJECTIVE: Sjögren syndrome is a systemic inflammatory disease causing gland dysfunction. Few (and contradictory) reports on the mucosal effects of Sjögren syndrome have appeared. Here, we objectively demonstrate nasal dryness in Sjögren syndrome patients and explore the effect of such dryness on olfaction. METHODS: Thirty-four consecutive patients with primary Sjögren syndrome were enrolled in this cross-sectional study. The control group consisted of 21 age- and sex-matched volunteers. Medical histories and nasal findings were recorded. The Connecticut Chemosensory Clinical Research Center test was used to evaluate olfactory function. All subjects underwent mucucociliary clearance analysis (the saccharin test and peak nasal inspiratory flowmetry). The intranasal Schirmer test was used to evaluate the nasal cavity. RESULTS: The nasal Schirmer test scores were 8.4 mm (right) and 8 mm (left) (P = .041, P = .016, respectively, compared to controls). The Chi-squared test revealed significant differences (compared to controls) in nasal dryness (P = .001), postnasal drip (P = .04), and smell (a decrease) (P = .005). Neither olfactory function nor mucociliary clearance differed between the groups. We noted a trend toward a positive correlation between olfactory function and the nasal Schirmer score but statistical significance was not attained. CONCLUSION: The intranasal Schirmer test objectively showed that Sjögren syndrome patients exhibited nasal cavity dryness; this is useful in terms of follow-up. This did not affect olfactory function. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:370-373, 2021. | |
32172462 | Peripheral neuropathy and health-related quality of life in patients with primary Sjögren | 2020 Aug | Sjögren's syndrome (SS) is a chronic autoimmune disease with a wide spectrum of possible organ involvement. Peripheral (PNS) and central nervous system (CNS)-related symptoms may occur in the course of the disease. The aim of this study was to compare the health-related quality of life (HR-QOL) in SS patients with and without peripheral neuropathy. The study involved 50 patients with primary Sjögren's syndrome (pSS). All patients underwent neurological clinical examination followed by nerve conduction studies (NCS) and rheumatological examination. Thirty-six-item Short Form Health Survey (SF-36) was used for evaluating HR-QOL. To assess pSS activity, the EULAR Sjögren's Syndrome Disease Activity Index (ESSDAI) and EULAR Sjögren's Syndrome Patient Reported Index (ESSPRI) were used. For the assessment of clinical disability due to peripheral neuropathy, the Overall Disability Sum Score scale (ODSS) was used. Additional evaluation of pain was performed with the use of the Visual Analogue Scale (VAS) and a semistructured interview. Twenty-three (46%) patients were diagnosed with peripheral neuropathy. The most common PNS manifestation was sensorimotor neuropathy (47%). Neurological symptoms preceded the diagnosis of pSS in eight patients. The following domains of the SF-36 form were significantly lower scored by patients with peripheral nervous system involvement: role-physical [0 (0-100) vs. 75 (0-100)], role-emotional [67 (0-100) vs. 100 (0-100)], vitality [40 (10-70) vs. 50 (20-75)], bodily pain [45 (10-75) vs. 55 (0-100)], and general health [20 (5-50) vs. 30 (0-50)] (p ≤ 0.05). Our study showed that peripheral neuropathy was a common organ-specific complication in SS patients. In pSS patients, coexisting neurological involvement with symptoms such as pain and physical disability may be responsible for diminished HR-QOL. | |
31960208 | Elevated plasma galectin-3 levels and their correlation with disease activity in adult-ons | 2020 Jun | OBJECTIVES: With galectin-3 playing an important role in inflammatory responses, elevated galectin-3 levels have been shown in patients with autoimmune diseases. However, there are limited data regarding galectin-3 expression in patients with autoinflammatory diseases such as adult-onset Still's disease (AOSD). This study aimed to investigate the extracellular galectin-3 expression and examine its association with activity parameters and disease outcome in AOSD patients. METHOD: Plasma levels of galectin-3 and inflammasome downstream cytokines including interleukin (IL)-1β and IL-18 were determined by ELISA in 42 active AOSD patients and 20 healthy controls (HC). The protein levels of galectin-3 and cytokines were determined using immunoblotting. RESULTS: Plasma levels of galectin-3 and inflammasome downstream cytokines including IL-1β and IL-18 were significantly higher in AOSD patients (median 5.02 ng/ml, interquartile range [IQR] 3.12-7.88 ng/ml; 3.42 pg/ml, IQR 1.48-6.70 pg/ml; and 5758 pg/ml, IQR 859-11,895 pg/ml, respectively) compared with HC (1.86 ng/ml, IQR 1.09-2.89 ng/ml; 0.99 pg/ml, IQR 0.62-1.35 pg/ml; and 129 pg/ml, IQR 71-155 pg/ml, respectively, all p < 0.001). Plasma galectin-3 levels were positively correlated with clinical activity scores, inflammatory parameters values, and the levels of IL-1β and IL-18 in AOSD patients. AOSD patients with systemic pattern had significantly higher galectin-3 levels (median 6.08 ng/ml, IQR 4.01-9.54 ng/ml) compared with those with chronic articular pattern (3.56 ng/ml, IQR 3.04-4.98 ng/ml, p < 0.05). After 6-month therapy, galectin-3 levels significantly declined, paralleling the decreases in clinical activity scores and plasma levels of IL-1β and IL-18. CONCLUSIONS: Elevated galectin-3 levels and their positive correlation with disease activity scores, inflammatory parameter, and inflammasome downstream cytokines suggest the involvement of galectin-3 in AOSD pathogenesis.Key Points• We revealed for the first time the association of plasma galectin-3 levels with AOSD activity parameters.• We explored the link between galectin-3 levels and NLRP3-inflammasome downstream cytokines in AOSD disease. | |
32540407 | Proteomics of saliva, plasma, and salivary gland tissue in Sjögren's syndrome and non-Sjà | 2020 Aug 15 | OBJECTIVE: The aim of this study was to characterize and compare the proteome in whole saliva, plasma, and salivary gland tissue in patients with primary Sjögren's syndrome (pSS) and patients having symptoms of pSS, but not fulfilling the classification criteria, and to search for diagnostic biomarker candidates for pSS. METHODS: Liquid chromatography tandem mass spectrometry was conducted on whole saliva, plasma, and labial salivary gland tissue samples from 24 patients with pSS and 16 non-Sjögren control subjects (non-pSS). Gene Ontology (GO)-terms and Kyoto Encyclopedia of Genes and Genomes (KEGG)-pathways were applied for functional annotation. RESULTS: 1013 proteins were identified in whole saliva, 219 in plasma, and 3166 in salivary gland tissue. In saliva, 40 proteins differed significantly between the two groups. In pSS, proteins involved in immunoinflammatory processes were upregulated, whereas proteins related to salivary secretion were downregulated. The combination of neutrophil elastase, calreticulin, and tripartite motif-containing protein 29 yielded a receiver-operating characteristic (ROC) value of 0.97 (CI 0.93-1.00). Protein expression in plasma and salivary gland tissue did not differ between the patient groups. CONCLUSION: The salivary proteome of patients with pSS differed from that of non-pSS patients, indicating that saliva proteomics represents a promising non-invasive diagnostic tool for pSS. SIGNIFICANCE: Primary Sjögren's syndrome (pSS) is a chronic systemic autoimmune disease, which clinically may present with a wide variety of symptoms and signs. Symptoms of dry eyes and dry mouth due to lacrimal and salivary gland dysfunction are prominent, but not pathognomonic, and an extensive diagnostic work-up including blood tests and labial salivary gland biopsy is often required to distinguish pSS from non-pSS. In this study, we used high throughput proteomics and identified a non-invasive biomarker candidate comprising a combination of three different upregulated salivary proteins, which enables differentiation between patients with pSS and non-pSS patients with an accuracy of 97%. In the future, this could contribute to earlier, more accurate and less costly diagnosis of pSS. |
