33187265 | T Cells Subsets in the Immunopathology and Treatment of Sjogren's Syndrome. | 2020 Nov 11 | Sjogren´s syndrome (SS) is an autoimmune disease whose pathogenesis is characterized by an exacerbated T cell infiltration in exocrine glands, markedly associated to the inflammatory and detrimental features as well as the disease progression. Several helper T cell subsets sequentially converge at different stages of the ailment, becoming involved in specific pathologic roles. Initially, their activated phenotype endows them with high migratory properties and increased pro-inflammatory cytokine secretion in target tissues. Later, the accumulation of immunomodulatory T cells-derived factors, such as IL-17, IFN-γ, or IL-21, preserve the inflammatory environment. These effects favor strong B cell activation, instigating an extrafollicular antibody response in ectopic lymphoid structures mediated by T follicular helper cells (Tfh) and leading to disease progression. Additionally, the memory effector phenotype of CD8+ T cells present in SS patients suggests that the presence of auto-antigen restricted CD8+ T cells might trigger time-dependent and specific immune responses. Regarding the protective roles of traditional regulatory T cells (Treg), uncertain evidence shows decrease or invariable numbers of circulating and infiltrating cells. Nevertheless, an emerging Treg subset named follicular regulatory T cells (Tfr) seems to play a critical protective role owing to their deficiency that enhances SS development. In this review, the authors summarize the current knowledge of T cells subsets contribution to the SS immunopathology, focusing on the cellular and biomolecular properties allowing them to infiltrate and to harm target tissues, and that simultaneously make them key therapeutic targets for SS treatment. | |
33068320 | Investigation of the relationship between the pelvic floor and sexual dysfunction in women | 2020 Dec | BACKGROUND AND AIM: Women with Sjögren's syndrome (SS) may have sexual dysfunctions due to vaginal dryness and may also have pelvic floor problems. The aim of this study was to examine the pelvic floor distress of women with SS with a self-reported questionnaire, to compare this group with healthy individuals, and to examine the relationship between pelvic floor problems and sexual dysfunction. METHODS: The study included 94 women with SS, aged 47.26 ± 7.56 years, and 94 age-matched healthy women, aged 48.15 ± 8.73 years. The Pelvic Floor Disease Inventory (PFDI-20), Pelvic Floor Impact Questionnaire (PFIQ-7), and Female Sexual Function Scale (FSFI) were used for assessment. RESULTS: The PFDI-20, PFIQ-7, and FSFI scores of the healthy control group were found to be statistically significantly better than those of the primary SS group (Z = -2.69 to -8.03, P = .00). A moderate-high correlation was found between the total and sub-parameters of PFDI-20 and disease duration, the total and sub-parameters of the PFIQ-7 and the pain sub-parameter and total score of the FSFI (r = -0.66 to 0.78, P = .00-.04). CONCLUSION: According to the study results, as the disease duration increases, the distress increases and this distress has a negative effect on the health-related quality of life of these women. Pelvic floor distress was associated with poor sexual function and pain. From these results, it can be recommended that the methods of pharmacology, education, exercise, relaxation, lifestyle change, and so on for pelvic floor dysfunction and pain in women with SS should be applied together with a multidisciplinary approach. | |
32413167 | Comparison of Clinical Characteristics and Magnetic Resonance Imaging of Salivary Glands W | 2021 Jan | OBJECTIVES/HYPOTHESIS: To compare the results of magnetic resonance imaging with magnetic resonance sialography (MRSIAL) and the clinical and laboratory characteristics in a well-characterized cohort of patients with primary or secondary Sjögren's syndrome (SS) meeting the American-European Consensus Group criteria. STUDY DESIGN: Retrospective, observational, monocentric study. METHODS: Thirty-six patients (81% female, mean age = 48 ± 35 years) with primary or secondary SS who underwent MRSIAL were included in the study. RESULTS: MRSIAL revealed characteristic radiological signs in the parotid, sublingual, and submandibular salivary glands in 35/36 patients (97%). Patients presenting with anti-Sjögren's syndrome-related antigen A (SSA) autoantibodies showed more often fatty infiltration, a "pepper-and-salt" appearance, ductal stenosis, and/or ductal dilation of the parotid gland (88%, 88%, and 72% respectively) than patients negative for anti-SSA (12%, 4%, and 28% respectively). MRSIAL demonstrated signs characteristic of SS in all 11 patients with negative minor salivary gland biopsy. For 15 patients undergoing ultrasound examination only, 11 (73%) had SS findings, but all 15 had SS findings on MRSIAL. Two cases of parotid lymphoma were detected by MRSIAL (6%). CONCLUSIONS: MRSIAL is a reliable technique to detect glandular anomalies in patients with SS, and seems to provide a valuable aid in the diagnosis of SS. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:E83-E89, 2021. | |
31578648 | Associated factors with interstitial lung disease and health-related quality of life in Ch | 2020 Feb | OBJECTIVE: The main purpose of this study was to investigate the current situation of primary Sjögren's syndrome (pSS) patients with interstitial lung disease (ILD) in China. The relationships between social demography, disease activity, psychological status, clinical variables, and ILD were analyzed. Besides that, the quality of life (QoL) in pSS with ILD was also analyzed. METHODS: In the cross-sectional study, 101 pSS patients participated in this study. Under the guidance of the researchers, the European League Against Rheumatism Sjögren's Syndrome Disease Activity Index (ESSDAI), EULAR Sjögren's Syndrome Patient-Reported Index (ESSPRI), the Short-Form 36 health survey (SF-36), Hospital Anxiety and Depression Scale (HADS), Pittsburgh sleep quality index (PSQI), Summated Xerostomia Inventory (SXI), and other related questionnaires were completed. Independent sample t tests, Mann-Whitney U test, chi-square test, and correlational analysis were used. RESULTS: The data showed that 28 (30.1%) pSS people with ILD. The occurrence and development of ILD were associated with disease duration, fatigue, alanine aminotransferase (ALT), neutrophils, albumin, and use of hormone. The survey also found that the QoL of pSS-ILD was significantly lower than non-ILD, especially the score in the dimension of role physical function. CONCLUSIONS: ILD was very common in pSS. ILD had a significant negative impact on the QoL of patients. Therefore, it is of great significance to strengthen the early intervention and drug treatment of pSS patients to prevent ILD and improve their QoL.Key Points• This cross-sectional study finds that the incidence of ILD in patients with pSS is 30.1%.• The occurrence and development of ILD is associated with disease duration, fatigue, alanine aminotransferase (ALT), neutrophils, albumin, and use of hormone.•The study also finds that the QoL of pSS-ILD is significantly lower than in patients with non-ILD, especially the score in the dimension of role physical function. | |
33327319 | Risk factors associated with relapse of adult-onset Still disease in Korean patients. | 2020 Dec 11 | Approximately 30% to 40% of all patients with adult-onset Still disease (AOSD) experience relapses, sometimes presenting as chronic damage, and these events can subsequently increase the morbidity and mortality in patients with AOSD. However, few studies are investigating the factors related to relapse in such patients. Therefore, this study aimed to explore the risk factors associated with relapse of AOSD.This cohort study enrolled 112 AOSD patients who satisfied the Yamaguchi criteria and obtained available data from Chonnam National University Hospital. The demographic, clinical, and laboratory data as well as treatment history of the patients from January 2008 to December 2019 were retrospectively reviewed. Relapse events were defined as the presence of one or more recurrent events. Multivariate logistic regression analysis was performed to investigate the possible risk factors for relapse.During a mean follow-up of 103.3 months, 47 of 112 patients (41.9%) developed a relapse. According to the results of multivariate logistic regression analysis, arthritis (odds ratio [OR] = 19.530, 95% confidence interval [CI]: 5.047-75.582, P < .001) and lymphadenopathy (OR = 6.539, 95% CI: 2.329-18.358, P < .001) predicted the development of recurrent events in patients with AOSD.Patients with AOSD had frequent relapses during the clinical course of their disease. Risk factors associated with flares were the presence of arthritis and lymphadenopathy. | |
33095138 | Clinically significant renal involvement in primary Sjögren's syndrome is associated with | 2020 Jul | OBJECTIVES: To investigate the prevalence, associated factors, and effects of primary overt renal disease on morbidity in patients with primary Sjögren's syndrome (pSS). METHODS: All patients in the Sjögrenser (registry of adult pSS patients of the Spanish Society of Rheumatology) cohort were retrospectively investigated for the presence of clinically significant renal involvement directly related to pSS activity. RESULTS: Of the 437 patients investigated, 39 (9%) presented overt renal involvement during follow-up. Severe renal disease necessitating kidney biopsy was relatively rare (2%). Renal involvement may complicate pSS at any time during the disease course and is associated with severe disease (indicated by higher scores of involvement, activity, and damage), systemic multiorgan involvement, and a higher frequency of lymphoma. Multivariate analysis showed that older age (odds ratio [OR] 1.03, 95% confidence interval [CI] 1.00-1.07), higher European League Against Rheumatism Sjögren's Syndrome Disease Activity Index scores (OR 1.1, CI 1.03-1.18), serum anti-La/SSB positivity (OR 6.65, CI 1.41-31.372), and non-vasculitic cutaneous involvement (OR 5.47, 1.03-29.02) were independently associated with this complication. Chronic renal failure developed in 23 of 39 patients (59%); only 1 of them progressed to end-stage renal disease necessitating renal replacement therapy. Patients with overt renal disease showed higher Sjögren's syndrome disease damage index scores, higher rates of hospitalisation due to disease activity and higher rates of clinically relevant comorbidities. CONCLUSIONS: Overt renal involvement in pSS is not uncommon. Although it usually shows a favourable prognosis, is associated with significant morbidity. | |
32934136 | National Sjögren's Foundation Survey: Burden of Oral and Systemic Involvement on Quality | 2021 Jul | OBJECTIVE: To define the association between oral and systemic manifestations of Sjögren syndrome (SS) and quality of life (QOL). METHODS: We analyzed a cross-sectional survey conducted by the Sjögren's Foundation in 2016, with 2961 eligible responses. We defined oral symptom and sign exposures as parotid gland swelling, dry mouth, mouth ulcers/sores, oral candidiasis, trouble speaking, choking or dysphagia, sialolithiasis or gland infection, and dental caries. Systemic exposures included interstitial lung disease, purpura/petechiae/cryoglobulinemia, vasculitis, neuropathy, leukopenia, interstitial nephritis, renal tubular acidosis, autoimmune hepatitis, primary biliary cholangitis, or lymphoma. Outcomes included SS-specific QOL questions generated by SS experts and patients. RESULTS: Using multivariable regression models adjusted for age, sex, race, and employment, we observed that mouth ulcers or sores, trouble speaking, and dysphagia were associated with poor quality of life. The following oral aspects had the greatest effect on the following QOL areas: (1) mouth ulcers/sores on the challenge and burden of living with SS (OR 4.26, 95% CI 2.89-6.28); (2) trouble speaking on memory and concentration (OR 4.24, 95% CI 3.28-5.48); and (3) dysphagia on functional interference (OR 4.25, 95% CI 3.13-5.79). In contrast, systemic manifestations were associated with QOL to a lesser extent or not at all. CONCLUSION: Oral manifestations of SS, particularly mouth ulcers or sores, trouble speaking, and dysphagia, were strongly associated with worse QOL. Further study and targeted treatment of these oral manifestations provides the opportunity to improve quality of life in patients with SS. | |
32896244 | Serious infections in Sjögren's syndrome patients: a national U.S. study. | 2020 Jul | OBJECTIVES: To study the incidence, time-trends and outcomes of serious infections in Sjögren's syndrome (SS). METHODS: We examined the epidemiology, time-trends and outcomes of five serious infections (opportunistic infections (OI), skin and soft tissue infections (SSTI), urinary tract infection (UTI), pneumonia, and sepsis/bacteremia) in hospitalised patients with SS, using the 1998-2016 U.S. National Inpatient Sample. Multivariable-adjusted logistic regression analyses analysed the association of patient, comorbidity and hospital characteristics with healthcare utilisation (hospital charges, length of hospital stay, discharge to non-home setting), and in-hospital mortality. RESULTS: We found 49,897,331 hospitalisations with serious infections in general population and 69,239 in patients with SS. Compared to serious infections hospitalisations in people without SS, SS patients were older, and more likely to be female, white or have Deyo-Charlson index score ≥2. Serious infections during the study period 1998-2016 were: OI, 3%; SSTI, 19%; UTI, 6%; pneumonia, 37%; and sepsis, 34%. Serious infection rates/100,000 NIS hospitalisations increased from 1998-2000 to 2015-2016: OI, 0.16 to 0.46; SSTI, 0.55 to 2.90; UTI, 0.25 to 1.96; pneumonia, 2.78 to 5.43; sepsis, 0.63 to 10.71. In multivariable-adjusted analyses, older age, Deyo-Charlson index score ≥2 and medium or large hospital bed size were associated with higher healthcare utilisation and in-hospital mortality. Medicare insurance, Northeast region, non-rural hospital were associated with higher healthcare utilisation outcomes only. CONCLUSIONS: We quantified the increasing disease burden of serious infections in people with SS, and described its epidemiology. Association of factors with serious infection hospitalisation outcomes identifies potential targets for future interventions. | |
32452353 | The treatment of adult-onset Still's disease with anakinra, a recombinant human IL-1 recep | 2021 Jan | Adult-onset Still's disease (AOSD) is a rare, inflammatory disease of unknown aetiology, generally affecting young adults and requiring immunosuppressive treatment. In the last few years, bio- logic disease-modifying anti-rheumatic drugs (bDMARDs) have been successfully used in refractory cases, based on the pathogenic role of inflammatory cytokines in AOSD. Amongst bDMARDs, several observations confirmed the clinical usefulness of anakinra, a recombinant human non-glycosylated IL-1 receptor antagonist, in AOSD. At present, the treatment is still largely empirical and due to the possible fallacious aspects of clinical judgement, in this work, we performed a systematic review of literature (SRL) to summarise the evidence regarding the treatment with anakinra in AOSD, analysing rate of complete remission, corticosteroids (CCSs)-sparing effect, long-term retention rate, and safety. After screening titles, abstracts and analysis of full text, 15 manuscripts were analysed: 1 open randomised multicentre trial with two parallel groups and 14 observational single-arm retrospective studies. Collectively, results of the present SRL suggest the effectiveness of anakinra in the treatment of patients with AOSD. Furthermore, patients with AOSD are likely to achieve a good clinical response with anakinra and these outcomes are associated with a largely favourable safety profile. Furthermore, the majority of patients treated with anakinra may achieve a complete remission, also in monotherapy. Finally, the treatment with anakinra is associated with an important CCSs-sparing effect, and, a large percentage of these patients may stop CCSs, thus reducing predictable long-term CCSs side effects without the occurrence of new flares. | |
32743513 | Programmed death ligand 2 - A link between inflammation and bone loss in rheumatoid arthri | 2020 | OBJECTIVE: Active rheumatoid arthritis (RA) is accompanied by increased appendicular and axial bone loss, closely associated to the degree of inflammation. The programmed death-1 (PD-1) pathway is important for maintaining peripheral tolerance, and its ligand PD-L2 has recently been associated with bone morphogenetic protein activity. Here, we report that PD-L2 plays a central role in RA osteoimmunology. METHODS: Femoral bone mineral density (BMD) and trabecular bone microstructure were evaluated by micro-CT in wild type (WT) and PD-L2(-/-) mice. Osteoclasts were generated from RA synovial fluid mononuclear cells and peripheral blood monocytes. The effects of recombinant PD-L2, was evaluated by tartrate-resistant acid phosphatase (TRAP) activity and the development of bone erosions in the presence of anti-citrullinated protein antibodies (ACPA). Plasma soluble (s)PD-L2 levels were measured in patients with early (e)RA (n ​= ​103) treated with methotrexate alone or in combination with the TNF inhibitor Adalimumab. RESULTS: PD-L2(-/-) mice had a decreased BMD and deteriorated trabecular bone microstructure that was not related to the RANKL/OPG pathway. PD-L2 decreased TRAP activity in osteoclasts and decreased ACPA-induced erosions. In the RA synovial membrane PD-L2 was highly expressed especially in the lining layer and plasma sPD-L2 levels were increased in eRA patients and decreased with treatment. One-year sPD-L2 correlated inversely with erosive progression two years after treatment initiation with methotrexate and placebo. CONCLUSION: PD-L2 regulates bone homeostasis in RA. Our findings provide new insight into the relationship between the immune system and bone homeostasis, and suggest a potential therapeutic target for limiting inflammatory bone loss in RA. | |
33013889 | Urinary Proteomics Identifying Novel Biomarkers for the Diagnosis of Adult-Onset Still's D | 2020 | Adult-onset Still's disease (AOSD) is a systemic, multigenic autoinflammatory disease, and the diagnosis of AOSD must rule out neoplasms, infections, and other autoimmune diseases. Development of a rapid and efficient but non-invasive diagnosis method is urgently needed for improving AOSD therapy. In this study, we first performed a urinary proteomic study using isobaric tags for relative and absolute quantification (iTRAQ) labeling combined with liquid chromatography-tandem mass spectrometry analysis in patients with AOSD and healthy control (HC) subjects. The urinary proteins were enriched in pathways of the innate immune system and neutrophil degranulation, and we identified that the α-1-acid glycoprotein 1 (LRG1), orosomucoid 1 (ORM1), and ORM2 proteins were highly expressed in patients with AOSD. The elevated urine levels of LRG1, ORM1, and ORM2 were further validated by enzyme-linked immunosorbent assay in active patients with AOSD, disease controls, and HC subjects. Receiver operating characteristic curves showed that the areas under the curve of LRG1, ORM1, and ORM2 were 0.700, 0.837, and 0.736, respectively (all p < 0.05). Furthermore, we found that the urine levels of LRG1, ORM1, and ORM2 were positively correlated with the systemic score and erythrocyte sedimentation rate and that the urine levels of LRG1 were positively correlated with interleukin 1β (IL-1β), IL-6, and IL-18 levels, whereas the urine levels of ORM1 were positively correlated with the IL-1β level. Together, our study identified novel urinary markers for non-invasive and simple screening of AOSD. | |
32892889 | Recurrent Life-threatening Pneumonitis in a 37-Year-Old Woman. | 2020 Sep | A 37-year-old previously healthy and athletic woman presented to the ED in October 2018 with acute-onset high fever, dyspnea, and productive cough. Chest radiograph showed bilateral infiltrates that correlated with multifocal ground glass opacities in a thoracic CT scan (Fig 1). The patient was severely hypoxemic and required intensive care and oxygen administration via a high-flow nasal cannula. On admission, leucocyte counts were 23.3 k/μL; platelet counts were 518 k/μL; hemoglobin level was 12 g/dL; C-reactive protein was 83 mg/L, and procalcitonin was 0.7 μg/L. An auto-antibody panel that included antinuclear antibodies, extractable nuclear antigen (including anti-centromere-antibodies), antineutrophil cytoplasmic antibodies, and myositis- and granulocyte macrophage colony-stimulating factor-antibodies was negative, as was the rheumatoid factor. Immunoglobulins that included IgG1-4 and IgA and renal function were normal. Sicca symptoms like xerophthalmia and xerostomia were negated. The patient fully recovered after empiric administration of antibiotics and glucocorticoids (initially 500 mg methylprednisolone daily over 3 days with consecutive tapering). | |
32799333 | Distinct microRNA expression profiles in saliva and salivary gland tissue differentiate pa | 2020 Nov | OBJECTIVES: Increasing evidence suggests that aberrant expression of microRNAs (miRNAs) is involved in the pathogenesis of primary Sjögren's syndrome (pSS). The aim was thus to characterize the miRNA profile in saliva, salivary gland tissue, and plasma from patients with pSS and compare findings with those of patients having Sjögren-like disease (non-pSS). In addition, to correlate miRNA levels and clinicopathological features of pSS. METHODS: miRNA real-time quantitative polymerase chain reaction was performed on saliva, plasma, and salivary gland tissue samples from 24 patients with pSS and 16 non-pSS in 384-well plates. T test was used for comparison of miRNA profiles, followed by Benjamini-Hochberg correction. The discriminatory power of miRNAs was evaluated by receiver-operating characteristic curves, and Pearson/Spearman correlation was used for correlation analyses. RESULTS: In saliva, 14 miRNAs were significantly differentially expressed between pSS and non-pSS, including downregulation of the miR-17 family in pSS. In salivary gland tissue of patients with pSS, miR-29a-3p was significantly upregulated. Plasma miRNAs did not differ between the two groups, although the miR-17 family tended to be downregulated. The combination of miR-17-5p and let-7i-5p in saliva yielded an area under curve of 97% (CI 92%-100%). Several miRNAs correlated significantly with one another and with salivary flow rates and histopathology. CONCLUSION: Our findings indicate that the miRNA expression profile in saliva may enable to discriminate between pSS and non-pSS patients. However, further validation in larger cohorts is needed as well as functional analyses of the miRNAs of interest. | |
32224257 | Complementary therapy with Traditional Chinese Medicine for a patient with Sjögren's synd | 2021 May | OBJECTIVE: . A case study was used to discuss the effects of Traditional Chinese Medicine (TCM) treatments on Sjögren's syndrome. CLINICAL FEATURES AND OUTCOMES: . A 45-year-old woman suffered from dry eyes, dry mouth, and fatigue for six months and was diagnosed with Sjögren's syndrome. She had received regular treatment with hydroxychloroquine (HCQ) and artificial tears as well as artificial saliva for nearly one year, but the results were unsatisfactory. Therefore, she sought CHM for further intervention. After 7 months of Yi-Guan-Jian with Huai-Xiao-Mai (Triticum aestivum Linn.) and Tian-Hua-Fen (Trichosanthis Radix), on the seventh treatment with TCM, she reported no fatigue or sleep dysfunction and relief of dry eyes and mouth. Neither complications nor side effects were noted during the CHM treatment. CONCLUSIONS: . From this case, we concluded that CHM may be an effective and safe alternative therapy for the treatment of Sjögren's syndrome. | |
32198090 | Entheses ultrasound assessment in primary Sjogren's syndrome. | 2020 Jul | OBJECTIVE: Musculoskeletal pain is a common complaint among patients with primary Sjogren's syndrome (pSS). Joints clinical examination is oftenly normal. A periarticular origin of this pain may be possible. Since clinical examination lacks sensitivity and precision, the use of musculoskeletal ultrasound (US) is more interesting in the evaluation of the entheses involvement, as it is shown to be a more sensitive tool. Our objective was to assess, by an ultrasonographic study, the entheses involvement in the widespread pain of patients with pSS. METHODS: This is a prospective study including 25 women with pSS and 25 age and sex matched healthy controls. An ultrasound examination, using grey scale and Doppler US, of five enthesitic sites (distal quadricipital, proximal patellar, distal patellar, distal Achillian and distal brachial tricipital) sought bilaterally the following lesions: hypoechogenicity, thickening, loss of fibrillar structure, erosions, enthesophytes, calcifications or Doppler hypervascularisation. A final score was calculated by summing the abnormalities scores of all entheses. RESULTS: The mean age was 53.2±11.3 years in the pSS group and 50.6±9.7 years in the control group. The mean number of pathological entheses on ultrasound was 3.92±1.93 in the pSS group versus 4.52±2.27 in the control group (P>0.05). The total score for enthesitis abnormalities was 4.96±2.59 versus 5.72±2.92 (P>0.05), respectively. There was a positive correlation between total score of ultrasound enthesitic abnormalities and age in both groups. CONCLUSION: In patients with pSS, clinically painful sites were more frequently found than in US. Musculoskeletal pain was not due to enthesitis. | |
33050949 | Autophagy occurs in lymphocytes infiltrating Sjögren's syndrome minor salivary glands and | 2020 Oct 13 | BACKGROUNDS: The organization of minor salivary glands (MSG) infiltrates, in patients with Sjögren's syndrome (SS), associates with disease severity and progression. Aberrant regulation of lymphocyte autophagy is involved in autoimmunity, and in previous work, we provided the first evidence of upregulated autophagy in CD4+ T cells infiltrating SS MSG. The aim of this study was to further explore autophagy in SS infiltrating and circulating lymphocytes and to investigate its role in disease histopathological progression. METHODS: After collection of 20 SS MSG, the presence of lymphocyte aggregates (foci) and the formation of germinal center (GC)-like structures were observed by H&E and confirmed by immunohistochemistry. The expression of autophagy-related genes, Atg5 and MAP1LC3A, was detected by RT-PCR on microdissected salivary gland tissue and control tonsils. In MSG and tonsils, autophagic lymphocytes were identified by the detection of the autophagosome protein LC3B visualized as LC3 puncta staining by immunofluorescence. Peripheral blood autophagy was assessed by flow cytometry in SS and healthy controls (HC). RESULTS: Real-time PCR demonstrated higher expression in the autophagy genes Atg5 and MAP1LC3A in MSG GCs as compared to both small foci (p = 0.0075, p = 0.0002) and GCs from tonsils (p = 0.0001, p = 0.0037). In MSG, LC3 puncta staining was detectable on both CD3+ and CD20+ lymphocytes; in tonsils, LC3 puncta was almost undetectable on all lymphocytes. Compared to HC (n = 20), flow cytometry did not reveal any increase of autophagy in SS circulating lymphocytes (n = 30). CONCLUSIONS: In SS MSG, lymphocytes' autophagy is a feature of infiltrating T and B cells and is associated with histological severity. Interestingly, in MSG aberrant regulation of autophagy is detectable in GC-like structures possibly indicating its involvement in the development and persistence of the autoimmune process within the lesions. | |
32434247 | [Inflammation in Dry Eye Disease - Information on Diagnostic Testing and Therapy Using the | 2020 May | Dry eye is considered the most common disease in ophthalmology. In recent decades, there has been intensive clinical and experimental research on this condition and our scientific knowledge of its pathophysiology has greatly expanded. The disease may be simple or severe and may lead to complex deregulation of the functional anatomy of the ocular surface, typically with a disparity between the clinical findings and the patient's symptoms. Chronic tissue injury induces various vicious circles that together lead to progressive worsening of the clinical picture. This can trigger inflammatory reactions that further intensify the disease process and can lead to the development of immunomodulated inflammation and a chronic pain syndrome. Both are relatively resistant to therapy in ordinary clinical practice. Better insight into the pathophysiological basics has enabled many approaches for innovations in diagnosis and therapy of dry eye. Nevertheless, sicca practice typically requires a great deal of time, usually offers only symptomatic therapy in everyday life and is often unsatisfactory for the patient and for his or her physician. For this reason, dry eye is often rather difficult to understand and difficult to manage. The scientific information platform of the Ocular Surface Center Berlin (OSCB-Berlin.org) aims to facilitate the understanding of the functional interactions at the ocular surface and thus also of the mechanisms involved in the complex pathophysiology of dry eye disease and of chronic inflammation. This is the basis for an up-to-date overview of dry eye diagnostic testing and therapy on different levels, which allows an understanding for clinicians and also for patients. | |
32696881 | Serum immunoglobulin a deficiency and autoimmune comorbidities: a crossectional study in 2 | 2020 Jun | OBJECTIVE To study the profile of associated autoimmune diseases in a series of patients with systemic lupus erythematosus (SLE) and see if such associations are linked to IgA deficiency. METHODS Two hundred eighty-one patients with SLE were studied for Ig A levels by nephelometry. Levels equal to or under 0.05g/dL were considered as IgA deficiency. Epidemiological and clinical data, including the presence of associated autoimmune diseases, were extracted from the patient's charts. RESULTS Ig A deficiency was found in 6% of the patients. In 30.2% of SLE patients, there was at least one more autoimmune disease; Hashimoto thyroiditis and Sjögren's syndrome were the most common. No association between the occurrence of associated autoimmune disease with IgA deficiency was found. CONCLUSIONS There is a high prevalence of autoimmune diseases associated with SLE. IgA deficiency does not affect the presence of these associations. | |
32459179 | Improving Quality of Care in Rheumatoid Arthritis Through Mobile Patient-Reported Outcome | 2020 May 27 | BACKGROUND: Patient-reported outcomes (PROs) for chronic disease management can be integrated into the routine workflow by leveraging mobile technology. OBJECTIVE: The objective of our study was to describe the process of our quality improvement (QI) efforts using tablets for PRO collection in a busy, academic rheumatology practice to support a treat-to-target (TTT) approach for rheumatoid arthritis (RA) management. METHODS: Our QI team designed a process for routine collection of PROs for RA patients at the Arthritis Center, employing information technology and an electronic medical record (EMR) system. Patients received a tablet at the clinic check-in desk to complete the Routine Assessment of Patient Index Data 3 (RAPID3) survey, a validated RA PRO. RAPID3 scores were uploaded to the EMR in real time and available for use in shared decision making during routine office visits. Weekly data were collected on RAPID3 completion rates and shared with front desk staff and medical assistants to drive improvement. Patients in our patient family advisory council and focus groups provided informal feedback on the process. RESULTS: From May 1, 2017, to January 31, 2019, a total of 4233 RAPID3 surveys were completed by 1691 patients. The mean age of patients was 63 (SD 14) years; 84.00% (1420/1691) of the patients were female, and 83.00% (1403/1691) of the patients were white. The rates of RAPID3 completion increased from 14.3% (58/405) in May 2017 to 68.00% (254/376) in September 2017 and were sustained over time through January 2019. Informal feedback from patients was positive and negative, relating to the usability of the tablet and the way rheumatologists used and explained the RAPID3 data in shared decision making during the office visit. CONCLUSIONS: We designed a sustainable and reliable process for collecting PROs from patients with RA in the waiting room and integrated these data through the EMR during office visits. | |
32210632 | Caesarean Delivery and Risk of Chronic Inflammatory Diseases (Inflammatory Bowel Disease, | 2020 | BACKGROUND: Chronic inflammatory diseases in childhood and early adult life share aetiological factors operating from birth and onwards. In this study, we use data from the national Danish health registers to evaluate the risk of developing four common, immune-mediated hospital-diagnosed childhood chronic inflammatory diseases. METHODS: A national population-based registry study. Data from the Danish Medical Birth Registry and the Danish National Patient Registry from January 1973 to March 2016 were linked at a personal level to evaluate any potential associations between caesarean section and development of Inflammatory bowel diseases, rheumatoid arthritis, coeliac disease and diabetes mellitus among the offspring. A model adjusted for parental age at birth, decade of birth, gender of child, and parents' chronic inflammatory disease status was used. RESULTS: This register-based national cohort study of 2672708 children with information on delivery mode found an increased risk of diabetes, arthritis, coeliac disease, and inflammatory bowel disease for both girls and boys after caesarean section compared with vaginal delivery. The higher risk was present at least 40 years after delivery. In a subgroup analysis, both acute and elective caesarean section was associated with an increased risk of developing a chronic inflammatory disease. CONCLUSIONS: Being born by caesarean section leads to increased host susceptibility for chronic inflammatory diseases that last for decades. This finding should be further addressed in future studies with the aim to support the development of new strategies for prevention, treatment, and maybe even cure. |
