29870527 Toxoplasmosis seroprevalence in rheumatoid arthritis patients: A systematic review and met 2018 Jun BACKGROUND: Toxoplasmosis is a cosmopolitan infection caused by an intracellular obligatory protozoan, Toxoplasma gondii. Infection to this parasite in immunocompetent patients is usually asymptomatic, but today it is believed that the infection can be a risk factor for a variety of diseases, including rheumatoid arthritis (RA). RA is an autoimmune disease and the most common type of inflammatory arthritis that is a major cause of disability. The aim of this systematic review and meta-analysis was to address the association between RA and toxoplasmosis in light of the available research. METHODS: Based on the keywords, a systematic search of eight databases was conducted to retrieve the relevant English-language articles. Then, the studies were screened based on the inclusion and exclusion criteria. The random effect model was used to calculate the odds ratio (OR) using forest plot with 95% confidence interval (CI). RESULTS: Overall, 4168 Individual, extracted from 9 articles were included for systematic review evaluation, with 1369 RA patients (46% positive toxoplasmosis) and 2799 individuals as controls (21% positive toxoplasmosis). Then, eight articles (10 datasets) were used for meta-analysis (1244 rheumatoid arthritis patients and 2799 controls). By random effect model, the combined OR was 3.30 (95% CI: 2.05 to 5.30) with P < 0.0001. CONCLUSION: Although toxoplasmosis could be considered as a potential risk factor for rheumatoid arthritis, more and better quality studies are needed to determine the effect of T. gondii infection on induction or exacerbation of RA. Our study was registered at the International Prospective Register of Systematic Reviews (PROSPERO; code: CRD42017069384).
29542372 Interleukin-6 and IgA-rheumatoid factor are crucial for baseline erosiveness, and anti-cit 2018 Sep OBJECTIVES: To define baseline clinical and immunological characteristics [anti-citrullinated peptide antibodies (ACPAs), immunoglobulin M (IgM)- and IgA-rheumatoid factor (RF), and interleukin-6 (IL-6) levels] involved in determining baseline erosiveness, outcome, and radiographic progression among seropositive and seronegative early rheumatoid arthritis (ERA) patients. METHOD: The 408 ERA patients enrolled in the study were monitored every 3 months according to the treat-to-target strategy. At baseline and after 12 months, hand and foot radiographs were evaluated using the Sharp/van der Heijde erosion score. RESULTS: At diagnosis, seronegative patients were older and had higher Disease Activity Scores (DASs) than seropositive patients. A higher risk of erosiveness at baseline was conferred by IgA-RF positivity and IL-6 plasma levels ≥7.6 pg/mL, particularly when simultaneously present. In multivariate analysis, disease duration and IL-6 plasma levels ≥7.6 pg/mL arose as independent variables associated with presence of erosions at onset. Radiographic progression at 1 year follow-up, which occurred in 11.1% of ERA patients, was predicted by ACPA positivity, together with higher age at diagnosis. Despite similar percentages of good European League Against Rheumatism response, DAS and Boolean remission being observed over time among seropositive and seronegative patients and between erosive and non-erosive subjects, ERA patients who were erosive at onset, IgA-RF seropositive, and simultaneously having high baseline IL-6 plasma levels (≥7.6 pg/mL) were treated to a greater extent with tumour necrosis factor blockers after 12 months. CONCLUSION: IgA-RF positivity and IL-6 plasma levels are crucial for baseline erosiveness, while ACPA positivity represents the strongest risk factor for developing radiographic progression in ERA.
30314507 Modulation of T-cell responses by anti-tumor necrosis factor treatments in rheumatoid arth 2018 Oct 12 Tumor necrosis factor (TNF) is a pleiotropic cytokine involved in many aspects of immune regulation. Anti-TNF biological therapy has been considered a breakthrough in the treatment of chronic autoimmune diseases, such as rheumatoid arthritis (RA). In this review, because of the major involvement of T cells in RA pathogenesis, we discuss the effects of anti-TNF biotherapy on T-cell responses in RA patients. We also outline the potential fields for future research in the area of anti-TNF therapy in RA.This could be useful to better understand the therapeutic efficiency and the side effects that are encountered in RA patients. Better targeting of T cells in RA could help set more specific anti-TNF strategies and develop prediction tools for response.
29756537 Use of negative pressure wound therapy in a chronic leg wound with coexisting rheumatoid a 2018 Jun We present a case of a 69-year-old woman with rheumatoid arthritis. The patient's condition was managed with steroid therapy for more than 12 years. She had a coexisting infected chronic ulceration in the left leg, which was treated with negative pressure wound therapy for 52 days. Use of this therapy within the wound reduced exudate and the bacterial count, which dramatically accelerated the process of wound healing.
29998844 Overweight and obesity affect clinical assessment of synovitis in rheumatoid arthritis: co 2019 Jan OBJECTIVES: Body mass index (BMI) might affect rheumatoid arthritis (RA) outcomes. Clinical assessment of swollen joint count (SJC) might also be affected by obesity in terms of obesity-related excess adipose tissue. In this study, we compared ultrasonography (US) and clinical examination in assessing the effect of BMI on RA disease activity assessment. METHODS: This was a single-centre study including RA (ACR/EULAR criteria) patients. US assessment was performed by one trained rheumatologist blinded to clinical data. US synovitis was defined as grey-scale score ≥2 and/or power Doppler score ≥1. The primary outcome measure was difference in SJC (ΔSJC) between clinical and US assessment (US-clinical examination). The secondary outcome was to evaluate the difference between clinical and US assessment of the Disease Activity Score in 28 joints (ΔDAS28) in the 3 BMI subgroups according to the WHO classification. RESULTS: We included 76 RA patients (mean age 53.8 ± 11.8 years; 67% female). Overall, 28 (36.8%), 33 (43.4%) and 15 (19.7%) were normal weight, overweight and obese, respectively. Baseline characteristics did not differ between the 3 BMI subgroups. US-determined SJC was significantly higher than clinical-determined SJC for overweight and obese RA patients: p=0.001 and p=0.049, respectively. The DAS28 was higher with US than clinical examination within the overweight group only (p=0.002). One-way analysis of variance (ANOVA) revealed a significant difference between ΔDAS28 among the 3 BMI subgroups (p=0.046). CONCLUSIONS: In high BMI RA patients both SJC and DAS28 seem to be undervalued by clinical assessment when compared to US.
29846271 Exercise is Associated With Increased Small HDL Particle Concentration and Decreased Vascu 2018 Dec OBJECTIVE: Patients with rheumatoid arthritis (RA) have increased cardiovascular (CV) risk. In the general population, exercise improves several CV risk factors. In a cross-sectional study, we examined the hypothesis that more exercise is associated with protective traditional and non-traditional CV risk factor profile in patients with RA. METHODS: Patient-reported exercise outside of daily activities was quantified by time and metabolic equivalents per week (METmin/week) and CV risk factors including blood pressure, standard lipid profiles, lipoprotein particle concentrations (NMR spectroscopy), and vascular indices were measured in 165 patients with RA. The relationship between exercise and CV risk factors was assessed according to whether patients exercised or not, and after adjustment for age, race and sex. RESULTS: Over half (54%) of RA patients did not exercise. Among those who did exercise, median value for exercise duration was 113 min/week [IQR: 60, 210], and exercise metabolic equivalent expenditure was 484 METmin/week [IQR: 258, 990]. Disease activity (measured by DAS28 score), C-reactive protein, waist-hip ratio, and prevalence of hypertension were lower in patients who exercised compared to those who did not (all p-values < 0.05) but standard lipid profile and body mass index were not significantly different. Patients who exercised had significantly higher concentrations of HDL particles (p = 0.004) and lower vascular stiffness as measured by pulse wave velocity (p = 0.005). CONCLUSIONS: More self-reported exercise in patients with RA was associated with a protective CV risk factor profile including lower waist-hip ratio, higher HDL particle concentration, lower vascular stiffness, and a lower prevalence of hypertension.
30073459 The incidence rate and the early management of rheumatoid arthritis in Slovenia. 2019 Feb Epidemiological data for rheumatoid arthritis (RA) differ according to ethnicity and geographical region. Moreover, despite of clear RA management guidelines, the implementation of treat-to-target (T2T) strategy often remains incomplete. Our objectives were to determine the incidence rate of RA, the clinical characteristics, and the level of adherence to the T2T guidelines in Slovenia. We analyzed prospectively the collected data of adult patients diagnosed with RA from 2014 through 2016 at the Department of Rheumatology, University Medical Centre Ljubljana, Ljubljana, Slovenia. The department provides rheumatology services to a well-defined region with a population of 704,000 adult residents. During the 3-year observation, we identified 341 incipient cases of RA (75% females, median (IQR) aged 64 (52.0-75.4) years), resulting in an annual incidence rate of 16.1 per 100,000 adults (95% CI 14.5-17.9). The incidence rate peaked in the 70-79-year age interval. The median time from the onset of symptoms suggestive of RA to rheumatology consultation was 12.9 (4.4-26.1) weeks, and the median time from referral to consultation was 1 (1-3) day. Within 12 weeks of symptom onset, 161 (47.2%) incipient RA patients were examined by a rheumatologist, and 123 (36.1%) were started on DMARD therapy. The estimated incidence rate was in line with the available epidemiological data. Our early interventional clinic enabled us to identify and manage a substantial portion of RA patients within the recommended time frame.
29718008 Correlation between Lung and Joint Involvement in Patients with Rheumatoid Arthritis and I 2018 BACKGROUND: Rheumatoid arthritis (RA) can affect the lungs in different manners, with interstitial lung disease (ILD) as the most serious manifestation. Although lung and joint compromise could be thought to evolve in parallel, there are data suggesting the opposite. In this study, we evaluated the relationship between lung and joint involvement in RA ILD. METHODS: An observational cross-sectional study of RA ILD patients evaluated from January 2015 to February 2017. Joint disease assessment included number of tender and swollen joints, patient's global assessment of disease activity, erythrocyte sedimentation rate (ESR) or C-reactive protein, and disease activity score (DAS28). Lung disease assessment included forced vital capacity, diffusion capacity (DLCO), and Goh high-resolution computed tomography (HRCT) score for total extent, ground glass, and reticular pattern. We studied the correlation between both components of the disease. RESULTS: We included 46 patients, 14 (30.4%) men, with a mean (SD) of the age of 59.9 years (11.89). 12 (26.09) patients were in remission or had low disease activity measured with DAS28. The HRCT showed usual interstitial pneumonia (UIP) pattern in 10 (21.7%), possible UIP in 18 (39.1%), and inconsistent with UIP in 18 (39.1%). We found a good correlation between the ESR and the ground glass score in the HRCT (r = 0.39; p = 0.03). However, we found no correlation between lung function tests or HRCT scores and the other components of the DAS28. CONCLUSIONS: We only found a good correlation between ESR and ground glass score. It is possible that different pathways of the immune response mediate damage in lungs and joints.
29144558 Association of oxidative stress with clinical characteristics in patients with rheumatoid 2018 Jan BACKGROUND: Few studies examining the association between oxidative stress and clinical parameters or disease activity in patients with rheumatoid arthritis (RA) are available. Therefore, the objective of this study was to test whether oxidative stress has any association with clinical parameters and disease activity in patients with RA. MATERIALS AND METHODS: In this post hoc cross-sectional study, 45 patients with RA treated with traditional disease-modifying antirheumatic drugs (DMARDs) ± low-dose glucocorticoids ± nonsteroidal analgesics for at least 3 months were analysed. Oxidative stress parameters were malondialdehyde (MDA), superoxide dismutase (SOD), antioxidant potential (AOP) and nonenzymatic superoxide radical scavenger activity (NSSA). Clinical parameters were pain, patient global assessment, physician global assessment, Health Assessment Questionnaire (HAQ), and disease activity score (DAS28). RESULTS: Plasma NSSA levels were significantly inversely correlated with tender joints count (r = -.304; P = .042), swollen joints count (r = -.342; P = .021) and DAS28 (r = -.396; P = .009). There were no significant correlations between MDA/SOD/AOP and any of clinical parameters or DAS28 (P > .05 for all). Multiple regression analysis revealed that NSSA was an independent variable of DAS28 (β=-.243, P = .016). CONCLUSION: The preliminary results demonstrate that plasma NSSA levels were inversely correlated with tender and swollen joints count and DAS28 and that NSSA was independently associated with DAS28, in patients with RA treated with traditional DMARDs; and provide initial support that NSSA may be used as a biomarker of disease activity in patients with RA.
29143384 Enhanced ventricular-arterial coupling during a 2-year physical activity programme in pati 2018 Dec OBJECTIVE: To establish how guided physical activity in patients with rheumatoid arthritis (RA) without known cardiovascular disease affected vascular and cardiac function, and how these two entities were prospectively interconnected in this patient group. METHODS: Prospective substudy of 29 participants in the Physical Activity in RA (PARA) 2010 trial. All subjects were examined at baseline, at year 1 and 2 with measures of pulse wave velocity and arterial augmentation index, as well as echocardiographic evaluation of diastolic parameters and ventricular-arterial coupling. Muscle strength and aerobic exercise capacity were assessed at baseline and yearly. All participants performed physiotherapist-guided aerobic and muscle strength exercise during 2 years and were reminded through SMS to report physical activity progress. RESULTS: This cohort of patients with RA exhibited increased vascular stiffness despite normal blood pressure. At baseline, lower muscle strength was associated with increased vascular stiffness (β = 0.68; P = 0.004), whereas lower aerobic working capacity was associated with left ventricular diastolic dysfunction (β = 0.85; P = 0.03). There was a significant positive correlation between vascular stiffness and diastolic dysfunction at baseline (R(2)  = 0.64) and for the changes in those parameters observed during 2 years of guided physical activity. Finally, a significant improvement in ventricular-arterial coupling was observed after exercise (P < 0.001). CONCLUSION: These results indicate that although differentially associated with physical capacity parameters, improved vascular stiffness and improved diastolic dysfunction are interrelated, and that an optimization of the ventricular-arterial coupling may contribute to the beneficial effects of physical activity in patients with RA.
29915991 Identifying markers of sustained remission in rheumatoid arthritis patients on long-term t 2018 Aug To identify features associated with long-term persistent remission in rheumatoid arthritis (RA) patients on tapered biological disease-modifying antirheumatic drugs (bDMARD) (tap-bDMARD) therapy. We carried out a 40-month (m) extension follow-up study of 77 RA patients from a previous 12 m tap-bDMARD study. Disease activity was assessed at baseline and every 3 months. Doppler US investigation of 42 joints for the presence and grade (0-3) of B-mode synovial hypertrophy (SH) and synovial power Doppler signal (i.e., Doppler synovitis) was performed before starting the tap-bDMARD strategy by a rheumatologist blinded to clinical and laboratory data. At the 40 m mark, 44 (57.1%) patients failed the tap-bDMARD strategy, while 33 (42.9%) succeeded. Patients who presented a failed tap-bDMARD had significantly longer disease duration, a longer time from symptom onset to synthetic (s) DMARD start, longer duration of sDMARD treatment, a greater number of sDMARDs, and a higher baseline DAS28 and SDAI than patients with successful tap-bDMARD at 40 months. In logistic regression analysis, the presence of baseline Doppler synovitis, a DAS28 ≥ 2.2, and the presence of rheumatoid factor were identified as predictors of tap-bDMARD failure at 40 m. In those patients who succeed tap-bDMARD at 12 m, a smoking habit was significantly more frequently found in tap-bDMARD failures at 40 m. Our results showed that DAS28 and the presence of Doppler synovitis, RF and a smoking habit predicted long-term tap-bDMARD failure.
30014755 Helicobacter pylori infection is not associated with rheumatoid arthritis. 2019 Jan OBJECTIVE: Rheumatoid arthritis (RA) is an autoinflammatory disease caused by genetic susceptibility and environmental triggers, which include infectious agents. Helicobacter pylori, a bacterium that frequently colonizes the stomach, is associated with the development of certain autoinflammatory disorders. This study examined a possible association between H. pylori infection and RA. METHOD: This cohort study was performed in the Central Denmark Region. Patients were enrolled from primary healthcare centres after a urea breath test (UBT) for H. pylori and followed for a median of 8 years. Nationwide administrative registries provided information about the patients' diagnoses, country of birth, and gender. Comorbidity was determined using the Charlson Comorbidity Index. We compared the prevalence of RA via odds ratios (ORs) and incidences using Cox regression to calculate the hazard ratios (HRs) by comparing H. pylori-positive and H. pylori-negative individuals and adjusting for confounding variables. RESULTS: A total of 56 000 people diagnosed as H. pylori positive or negative had similar rates of comorbidity. No link was found between H. pylori and RA. There was no difference in RA prevalence until time of UBT [OR = 0.91, 95% confidence interval (CI) 0.70-1.19)] or incidence of new RA cases after UBT (HR = 0.80, 95% CI 0.56-1.13) between H. pylori-positive and -negative subjects. Validation via four other RA definitions provided similar results. CONCLUSION: This study found no association between H. pylori infection and RA. This result does not support the involvement of H. pylori in a gut-joint axis of importance for RA development.
29170107 Analytical and clinical comparison of two fully automated immunoassay systems for the dete 2018 Jan BACKGROUND: Detection of antinuclear antibodies (ANA) by indirect immunofluorescence assay (IIFA) is increasingly substituted by fully automated solid phase immunoassays. This study evaluated the performance of an automated chemiluminescence immunoassay (CIA) and fluorescence enzyme immunoassay (FEIA) and compared their performance to that of IIFA. METHODS: The study included an unselected prospective study population suspected of systemic autoimmune rheumatic disease. ANA were measured by IIFA, while in parallel sera were tested by CIA QUANTA Flash CTD Screen Plus on the BIO-FLASH® and FEIA EliA CTD Screen on the Phadia® 250 system. As validation, retrospective cohorts of patients with ANA-associated rheumatic disease (AARD) and healthy controls were tested. RESULTS: Prospectively, sensitivity of IIFA, CIA and FEIA was 90%, 99% and 92%, respectively. Specificity was 76%, 76% and 84%, respectively. Total percent agreements between the three methods were 75.2% (IIFA vs. CIA), 79.2% (IIFA vs. FEIA) and 85.4% (FEIA vs. CIA). The AUC values were 0.95 for CIA and 0.93 for FEIA and did not significantly differ. Retrospectively in individual AARD cohorts, similar results were obtained comparing both CTD screens. CONCLUSIONS: Both FEIA and CIA CTD screen significantly outperformed IIFA, with a higher specificity for FEIA and higher sensitivity for CIA. Based on ROC analysis, major contributor to the difference between the two solid phase immunoassays was the cut-off.
29804189 Anti-inflammatory Effect of Somatostatin Analogue Octreotide on Rheumatoid Arthritis Synov 2018 Oct Somatostatin and its analogues are known to have modulatory effects on immune response and their anti-proliferative, anti-angiogenic, and analgesic properties make them attractive candidates for a therapeutic use in immune-mediated diseases, such as rheumatoid arthritis. Here, we demonstrate the ability of the somatostatin analogue octreotide to inhibit interleukin-15 and to increase interleukin-10 production by rheumatoid arthritis fibroblast-like synovial cells maintained in a chronic inflammatory state. We also prove that the inhibitory effect of octreotide on interleukin-15 and tumor necrosis factor-α production depended on the increase in interleukin-10, since neutralizing anti-interleukin-10 antibody was able to partially reverse this inhibition. In addition, our observations suggest an octreotide control on purinergic signaling, with an inhibitory effect on purinergic P2X and P2Y receptors activation. This would have great implications, considering the roles of P2 receptors in the onset of inflammation. Data here reported extend knowledge on the biological action of octreotide and underline its multiple effects on immune response, which could make octreotide an attractive and valid support for the therapy of diseases where several inflammatory mediators are involved, such as rheumatoid arthritis, and in which the simultaneous action on different aspects can be a successful strategy.
28980908 Serum IL-7 as diagnostic biomarker for rheumatoid arthritis, validation with EULAR 2010 cl 2018 Jan OBJECTIVES: Despite the well-established value of currently used classification criteria for the early diagnosis of rheumatoid arthritis (RA) there is a constant demand for novel biomarkers notably in autoantibody-negative patients. Interleukin 7 (IL-7) has been reported as a candidate diagnostic biomarker based on ACR-1987 criteria. However, clinical practice has moved to using the EULAR 2010 classification criteria. Therefore, to advance the use of IL-7 alongside the RA biomarker pipeline, we repeated the original study in a new cohort. METHODS: 255 patients were recruited. IL-7 was quantified by ELISA. Univariate and regression analyses were used to model RA diagnosis. RESULTS: 123 patients were diagnosed with RA (EULAR 2010) while 132 were classified as non-RA. In univariate analysis, RA was associated with autoantibodies and SE-positivity, higher joint counts, DAS28 (all p<0.001) and CRP (p=0.024). IL-7 was lower in RA (p=0.05). Logistic regression analysis in 227 patients with complete data set confirmed IL-7 was the second best predictive marker (p=0.035) following SJC (p=0.007) with good model fit (AUROC=0.889). A second model investigated 147 ACPA-negative patients: lower IL7 was the second best predictive marker (p=0.075) behind SJC (p=0.013). CONCLUSIONS: This study validates our previous results from a UK cohort using EULAR 2010 criteria although the predictive power associated with IL-7 is lower than in the study using ACR 1987 criteria (both French/UK cohorts). IL-7 remains a potential biomarker for ACPA-negative RA although further validation with larger numbers of ACPA-negative patients is still needed notably to translate these results into clinical applicability.
29706965 Transcription Factor SOX5 Promotes the Migration and Invasion of Fibroblast-Like Synoviocy 2018 OBJECTIVES: Fibroblast-like synoviocytes (FLS) exhibit a unique aggressive phenotype in rheumatoid arthritis (RA). Increased FLS migration and subsequent invasion of the extracellular matrix are essential to joint destruction in RA. Our previous research reported that transcription factor SOX5 was highly expressed in RA-FLS. Here, the effects of SOX5 in RA-FLS migration and invasion will be investigated. METHODS: The migration and invasion of RA-FLS were evaluated using a transwell chamber assay. The expression of several potential SOX5-targeted genes, including matrix metalloproteinases (MMP-1, 2, 3 and 9), chemokines (CCL4, CCL2, CCR5 and CCR2), and pro-inflammatory cytokines (TNF-α and IL-6), were examined in RA-FLS using SOX5 gain- and loss-of-function study. The molecular mechanisms of SOX5-mediated MMP-9 expressions were assayed by luciferase reporter gene and chromatin immunoprecipitation (ChIP) studies. The in vivo effect of SOX5 on FLS migration and invasion was examined using collagen-induced arthritis (CIA) in DBA/1J mice. RESULTS: Knockdown SOX5 decreased lamellipodium formation, migration, and invasion of RA-FLS. The expression of MMP-9 was the only gene tested to be concomitantly affected by silencing or overexpressing SOX5. ChIP assay revealed that SOX5 was bound to the MMP-9 promoter in RA-FLS. The overexpression of SOX5 markedly enhanced the MMP-9 promoter activity, and specific deletion of a putative SOX5-binding site in MMP-9 promoter diminished this promoter-driven transcription in FLS. Locally knocked down SOX5 inhibited MMP-9 expression in the joint tissue and reduced pannus migration and invasion into the cartilage in CIA mice. CONCLUSION: SOX5 plays a novel role in mediating migration and invasion of FLS in part by regulating MMP-9 expression in RA.
30272996 Critical role of IL-1α in IL-1β-induced inflammatory responses: cooperation with NF-κBp 2019 Feb The IL-1 cytokines are considered among the first family of cytokines that orchestrate acute and chronic inflammatory diseases. Both IL-1β and IL-1α are members of the IL-1 family; however, their distinct roles in the inflammatory processes remain poorly understood. We explored the role of IL-1α in IL-1β-activated signaling pathways causing synovial inflammation in rheumatoid arthritis (RA). Using synovial fibroblasts isolated from RA joints, we found that IL-1β significantly stimulated IL-1α expression, which was selectively inhibited by blocking the NF-κB pathway. Knockdown of IL-1α using small interfering RNA abolished IL-1β-induced pro-IL-1α and pro-IL-1β expression and suppressed inflammation. Native and chromatin immunoprecipitation studies showed that IL-1α cooperates in NF-κBp65 binding to the distal region of IL-1α promoter and to the proximal region of IL-1β promoter upstream of the transcription start site to stabilize their gene transcription. Molecular dynamics simulation of IL-1α or IL-1β binding to IL-1 receptor showed distinct interaction sites that corroborate with the ability of IL-1α to differentially activate phosphorylation of signaling proteins compared with IL-1β. Our study highlights the importance of IL-1α in mediating IL-1β-induced inflammation in addition to maintaining its expression and providing a rationale for targeting IL-1α to minimize the role of IL-1β in inflammatory diseases like RA.-Singh, A. K., Fechtner, S., Chourasia, M., Sicalo, J., Ahmed, S. Critical role of IL-1α in IL-1β-induced inflammatory responses: cooperation with NF-κBp65 in transcriptional regulation.
28359231 Gold - Old Drug with New Potentials. 2018 BACKGROUND: Research into gold-based drugs for a range of human diseases has seen a revival in recent years. This article reviews the most important applications of gold products in different fields of human pathology. Au(I) and Au(III) compounds have been re-introduced in clinical practice for targeting the cellular components involved in the onset and progression of viral and parasitic diseases, rheumatoid arthritis and cancer. RESULTS: After some brief historical notes, this article takes into account the applications of gold compounds against Mycobacterium tuberculosis, and also in tuberculosis and in rheumatoid arthritis treatment. The use of gold containing drugs in the cure of cancer are then considered, with special emphasis to the use of nanoparticles and to the photo-thermal cancer therapy. The use of colloidal gold in diagnostics, introduced in the last decade is widely discussed. As a last point a survey on the adverse effects and on the toxicity of the various gold derivatives in use in medicine is presented. CONCLUSION: In this review, we described the surprisingly broad spectrum of possible uses of gold in diagnostics and in therapeutic approaches to multiple human diseases, ranging from degenerative to infectious diseases, and to cancer. In particular, gold nanoparticles appear as attractive elements in modern clinical medicine, combining high therapeutic properties, high selectivity in targeting cancer cells and low toxicity.
30452329 Primary Sjögren's syndrome. 2018 Oct Primary Sjögren's syndrome (pSS) is a systemic autoimmune disorder characterized by focal lymphocytic infiltration of the exocrine glands causing dry eyes and dry mouth. Similar glandular features can also occur as a late complication in patients with other rheumatic disorders, such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and scleroderma ('secondary' Sjögren's syndrome).(1) Anti-Ro and/or anti-La (ENA) antibodies are found in approximately 70% of pSS patients, generally with ANA positivity. Hypergammaglobulinaemia is also common. Systemic features also occur in some patients with pSS. A positive rheumatoid factor (RF) is often seen and so if patients present with arthritis, dryness and a positive RF a diagnosis of pSS should be considered as a possible alternative to RA. Anti-CCP antibodies are more specific for RA.
29798700 Long-term deterioration of interstitial lung disease in patients with rheumatoid arthritis 2019 May OBJECTIVE: To examine the deterioration of interstitial lung disease (ILD) in patients with rheumatoid arthritis (RA) treated with abatacept over the long-term. METHODS: We examined 131 patients with RA who had been treated with abatacept for more than 1 year. All patients underwent high-resolution computed tomographic (HRCT) scanning of the chest before administration of abatacept, and we examined deterioration of ILD over a follow-up period after administration of abatacept was initiated. RESULTS: Eleven patients (8.4%) showed deterioration of ILD over a mean follow-up period of 47.8 months. The factors related to ILD deterioration were use of methotrexate (MTX) [odds ratio 12.75, 95% confidence interval (CI) 1.09-148.77], and change in Krebs von-den Lungen-6 (odds ratio 1.00, 95% CI 1.00-1.01), according to multivariate logistic regression analysis. CONCLUSION: MTX in patients with RA treated with abatacept was a risk factor for deterioration of ILD. Discontinuation of MTX should be considered one of treatment reduction to prevent the deterioration of ILD.
