"Atherosclerotic" phenotype of rheumatoid arthritis. What do we know about it?

Several studies have shown that systemic rheumatoid inflammation may cause induction and accelerated progression of atherosclerotic vascular lesions, which in turn may lead to more frequent development of cardiovascular diseases (CVD) in patients with rheumatoid arthritis (RA) compared to the general population.Objective. To evaluate the presence, nature and role of conventional and RA-specific risk factors for the development of CVD in patients with active RA in real-life clinical practice.Material and methods. Data from 967 patients with confirmed active RA were analyzed. Biologic disease-modifying antirheumatic drugs (DMARDs) or targeted DMARDs were prescribed/switched due to the ineffectiveness of previous therapy. Patients were divided into two groups: with and without CVD. In addition, comparable age subgroups of elderly (60–74 years) and middle-aged (45–59 years) patients were formed in each group. In all patients, clinical and laboratory parameters of RA activity, presence of extra-articular manifestations, the severity and progression of RA and characteristics of pharmacotherapy were analyzed. In addition, concomitant diseases and several traditional risk factors for the development of CVD were analyzed in all RA patients.Results and discussion. In patients with similar RA activity and duration, there is a parallel, tatistically significant accumulation of traditional CVD risk factors with increasing age-related CVD. The incidence of arterial hypertension, diabetes mellitus, chronic kidney disease, chronic obstructive pulmonary disease, thyroid pathology, anemic syndrome, dyslipidemia, hyperuricemia and obesity was significantly higher in the group of elderly RA patients with CVD than in the group of middle-aged patients.Conclusion. It seems appropriate to identify a specific variant of RA that is closely associated with atherosclerosis.

Are there differences in the clinical and laboratory features of patients with seronegative primary Sjögren's syndrome?

The objective of this study was to demonstrate the commonalities and distinctions between patients with seronegative and seropositive primary Sjögren's syndrome (pSS). The records of 399 patients with pSS seen between January 2010 and June 2023 were retrospectively examined. Patients with negative antiSSA/Ro, antiSSB/La, ANA, and RF antibodies comprised the seronegative group, while patients with at least one positive antibody were included in the seropositive group. The most common clinical features between the groups were arthralgia (81.2%), arthritis (11.5%), hematological involvement (19.8%), and pulmonary involvement (11.8%). In 41 patients (10.3%), no autoantibody positivity was detected. The number of patients with at least one extraarticular involvement was statistically more frequent in the seropositive group (p = 0.011). Dry mouth was found to be more prevalent among seronegative patients (p = 0.003). While hyperimmune gammaglobulinemia exhibited a higher prevalence within the seropositive group (p = 0.004), the occurrence of reduced complement levels was at similar rates in both groups. All deaths were observed exclusively within the seropositive group (17/358, 4.7%). No difference was observed between the two groups concerning mortality (p = 0.237) and malignancies (seropositive group: 9/358, 2.5% vs. seronegative group: 3/41, 7.3%, p = 0.115). There was a statistically significant association between low C4 levels (OR = 2.99 [1.09-8.16], p = 0.045 in model 1, OR = 3.10 [1.14-8.42], p = 0.022 in model 2), and the extraarticular findings. While hematological, renal, pulmonary, and neurological involvements are observed with similar frequency in both seronegative and seropositive pSS patients, the presence of extraarticular manifestations was more common in seropositive patients. Additionally, there was a relationship between extraarticular involvement and low C4 levels.

Diffuse idiopathic skeletal hyperostosis and axial spondyloarthritis—similarities and differences

Diffuse idiopathic skeletal hyperostosis (DISH) and axial spondyloarthritis (axSpA) are diseases with inflammatory involvement of the axial skeleton that can result in new bone formation that may lead to total ankylosis of the spine and functional impairment of different extent in individual patients. In these diseases, the new bone formation may lead to total ankylosis of the spine and impaired mobility with functional impairment. This review will highlight the similarities and differences of these two conditions. In axSpA, the genetic background with the association with human leukocyte antigen-B27 (HLA-B27) is known for 50 years, while in DISH, a genetic contribution is not yet proven. The phenotype of new bone formation and its anatomic features are different between these diseases. In axSpA symmetric, thin and marginal syndesmophytes representing an ossification of enthesitic inflammation at the area of the attachment of the annulus fibrosus that may extend to the adjacent deeper layers anterior longitudinal ligament and are typical, while in DISH the so-called “chunky bridging osteophytes” grow as an additional layer on the anterior longitudinal ligament. Besides distinct anamnestic and clinical features, magnetic resonance imaging is helpful differentiating the two diseases since inflammatory changes with the typical pattern of axSpA are reliably visualized. Similar in both diseases is the high prevalence of vertebral fractures, which are mainly caused by the local osteoporosis and decreased flexibility of the affected bones, and therefore may occur even after minor traumata. The presence of extraarticular manifestations like uveitis, inflammatory bowel disease or psoriasis are only linked to axSpA. In contrast, DISH is associated with obesity, diabetes mellitus, and other metabolic diseases. Although DISH and axSpA are distinct conditions, the cooccurrence of these two diseases exists in some patients. Various therapeutic options are becoming available for axSpA, but no therapy has been approved for DISH yet.

Clinical significance of tocilizumab-related neutropenia in patients with rheumatoid arthritis.

To determine the risks and clinical significance of tocilizumab (TCZ)-related neutropenia, in real-world settings, for patients with rheumatoid arthritis (RA). Medical records of RA patients treated with TCZ at a tertiary referral hospital in South Korea were collected. Infectious complications were defined as cases confirmed by clinical diagnosis and treated with antibiotics. A total of 277 RA patients with TCZ treatment (intravenous: 152 [54.9%], subcutaneous: 125 [45.1%]) were included in our study. During the observational period, 22 (7%) patients experienced grade 3 neutropenia. No patients discontinued TCZ due to neutropenia, while the dosage of conventional synthetic DMARD (csDMARD) was either reduced or discontinued for 8 patients. Patients, who experienced neutropenia while using csDMARD, had a higher risk for grade 3/4 neutropenia during TCZ treatment (hazard ratio [HR]: 3.120, 95% CI: 1.189-8.189, P=0.021). Among infections, pulmonary infections were the most common (10.35 per 100 patient-years). Age over 60 years (HR: 2.133, 95% CI: 1.118-4.071, P=0.022) and the presence of extra-articular manifestations (adjusted HR: 11.096, 95% CI: 5.353-22.999, P<0.001), but not neutropenia (adjusted HR: 1.263, 95% CI: 0.269-5.945, P=0.77), were risk factors for infections during TCZ treatment. Approximately 7% of RA patients treated with TCZ developed grade 3 neutropenia. The previous history of neutropenia during csDMARD was a risk factor for TCZ-related neutropenia. Age and extra-articular manifestations, but not neutropenia, were risk factors for infection during TCZ treatment, suggesting that TCZ treatment can be maintained in the presence of neutropenia unless infection occurs.

Cardiometabolic multimorbidity may identify a more severe subset of rheumatoid arthritis, results from a “real-life” study

This "real-life" cross-sectional study has been designed to describe disease features of rheumatoid arthritis (RA) participants affected by cardiometabolic multimorbidity than those without. Our purpose was also the identification of possible associations between these cardiometabolic diseases and RA clinical characteristics. Consecutive RA participants with and without cardiometabolic multimorbidity were assessed and their clinical characteristics were recorded. Participants were grouped and compared by the presence or not of cardiometabolic multimorbidity (defined as ≥ 2 out of 3 cardiovascular risk factors including hypertension, dyslipidemia, and type 2 diabetes). The possible influence of cardiometabolic multimorbidity on RA features of poor prognosis was assessed. The positivity of anti-citrullinated protein antibodies, presence of extra-articular manifestations, lack of clinical remission, and biologic Disease-Modifying anti-Rheumatic Drugs (bDMARDs) failure were considered as RA features of poor prognosis. In the present evaluation, 757 consecutive RA participants were evaluated. Among them, 13.5% showed cardiometabolic multimorbidity. These were older (P < .001) and characterized by a longer disease duration (P = .023). They were more often affected by extra-articular manifestations (P = .029) and frequently displayed smoking habit (P = .003). A lower percentage of these patients was in clinical remission (P = .048), and they showed a more frequent history of bDMARD failure (P < .001). Regression models showed that cardiometabolic multimorbidity was significantly correlated with RA features of disease severity. They were predictors of anti-citrullinated protein antibodies positivity, of extra-articular manifestations, and of lack of clinical remission, in both univariate and multivariate analyses. Cardiometabolic multimorbidity was significantly associated with a history of bDMARD failure. We described disease features of RA participants with cardiometabolic multimorbidity, identifying a possible more difficult to treat subset, which may need a new management approach to achieve the treatment goal.

Clinical Factors and the Outcome of Treatment with Methotrexate in Rheumatoid Arthritis: Role of Rheumatoid Factor, Erosive Disease and High Level of Erythrocyte Sedimentation Rate.

To identify the clinical factors predicting the outcome of treatment with methotrexate in rheumatoid arthritis, we examined 312 patients (253 females, 59 males) with rheumatoid arthritis diagnosed according to the criteria of the American College of Rheumatology. All patients included in this analysis began treatment with a regimen of oral MTX 7.5 mg weekly, with the dosage increasing to 15 mg weekly after 4 weeks, in combination with folic acid (1 mg daily). Good responders were defined as patients who had a DAS28 of ≤2.4 at 6 months (patients with remission of disease symptoms). Poor responders were defined as patients who had a DAS28 of >2.4. In this study, we analyzed the association between clinical parameters such as sex of patients, age of patients, age at disease onset, disease duration, rheumatoid factor, anti-CCP antibodies, ESR values, presence of joints erosions, presence of extra-articular manifestations and the response to MTX in RA patients. Multivariate logistic regression analysis showed four independent factors significantly associated with good response to MTX treatment: older age at disease onset, low ESR, no erosive disease and negative RF. The results of our study suggest that a younger age at disease onset, the presence of RF, erosive disease, as well as a high level of ESR are associated with worse response to MTX therapy.

13 Juvenile idiopathic arthritis and cardiovascular risk factors

BackgroundJuvenile idiopathic arthritis (JIA) is the most common pediatric rheumatic disease. Although, some patients achieve remission, some cases of JIA may persist into adulthood. Patients with JIA and other inflammatory joint diseases have increased cardiovascular disease risk compared with the general population.ObjectivesTo study the cardiovascular risk factors in JIA and their association with disease parameters.MethodsThis was a retrospective study including adults with long-standing JIA according to the International League of Associations for Rheumatology (ILAR) criteria over a period of 28 years (1994–2022). We collected sociodemographic and anthropometric parameters, clinical data, results of biological assessments, and data on prescribed therapies.We studied the following cardiovascular risk factors: family history of cardiovascular event, physical inactivity, smoking, arterial hypertension, diabetes, dyslipidaemia and obesity.ResultsWe included 29 patients. The M/F sex ratio was 0.71, the mean age was 35.69 ± 11.72 [18–61] years. The mean age of disease onset was 11.10 ± 4.25 [2–16] years. The average diagnostic delay was 52.96 ± 95.97 [0–336] months. The average disease duration was 24.48 ± 12.76 [1–47] years. The mean BMI was 21.20 ± 4.88 kg/m2 [14.17–27.55].The polyarticular form was the most frequent, noted in 55.2% of cases (n = 16). Extra-articular manifestations were observed in 55.2% of cases. Mean CRP was 42.74 ± 63.37 [2–218] mg/l and biological inflammatory syndrome was present in 19 cases. Rheumatoid factor, ACPA and anti-nuclear antibodies were observed in 12, 7 and 5 cases respectively.Corticosteroid therapy and NSAIDs were prescribed to 18 of the subjects.Cardiovascular risk factors were present in 41.4% (n = 12) of cases: family history of cardiovascular event (n = 2 cases), physical inactivity (n = 5 cases), smoking (n = 3 cases), arterial hypertension (n = 4 cases), diabetes (n = 4 cases), dyslipidaemia (n = 4), and BMI ≥ 25 kg/m² (n = 4).Following parameters were significantly higher in patients with cardiovascular risk factors: the presence of a biological inflammatory syndrome (81.8% vs 35.3%; p = 0.016), the frequency of prescription of corticosteroids (91.7% vs 52.9%; p = 0.026) and NSAIDs (83.3% vs 47.1%; p = 0.047).However, no significant difference was noted when comparing these parameters: gender, age, age of disease onset, disease duration and presence of extra-articular manifestations. Moreover, cardiovascular risk factors were not associated with the presence of rheumatoid factor, ACPA, and antinuclear antibodies.ConclusionInflammation, corticosteroid therapy and NSAIDs are associated with the presence of cardiovascular risk factors in JIA. The evaluation and control of this risk must be regular during patient follow-up. Control of inflammation and rationalization of treatment are necessary.

Analysis of the relationship between the response to methotrexate therapy and its pharmacokinetic parameters in rheumatoid arthritis. Sovremennaya Revmatologiya

The development of therapeutic drug monitoring of methotrexate (MT) remains an important and unresolved problem.Objective: to study the dynamics of the concentration of MT metabolites in groups of patients with different responses to MT therapy, to identify the clinical features of these groups.Patients and methods. The study included 79 patients with rheumatoid arthritis (RA), including 65 (82%) women and 14 (18%) men (mean age 53±11 years). MT monoglutamate was measured in erythrocytes (ER) and mononuclear cells (MO), as well as the main MT metabolites: polyglutamates with 2, 3 and 4 glutamate residues (MTPG2-4), as well as 7-hydroxymethotrexate (7-OH-MT) after 4, 12, 24 and 36 weeks after the start of MT treatment.Results and discussion. Among the patients who completed the 24-week follow-up, 34 responded to MT therapy (Group 1) and 36 did not respond to it (Group 2). Patients of the two groups did not differ in the concentration of various metabolites of MT after 4 weeks, age, body mass index, duration of RA, DAS28 value, radiological stage, functional class, presence of extra-articular manifestations, single and cumulative doses of MT. In the 1st group after 12 weeks of therapy, a higher concentration of 7-OH-MT (ER) was detected, after 24 weeks – a higher concentration of 7-OH-MT (MO) and a lower level of MTPH3 (ER).Conclusion. The concentration of 7-OH-MT after 12 and 24 weeks of therapy was higher in the group of patients who responded to therapy. 7-OH-MT appears to be a more persistent metabolite of MT and therefore more applicable for therapeutic drug monitoring of MT. The level of MT and its metabolites (MT monoglutamate, MTPG2 and 7-OH-MT) gradually decreases over time in responders to therapy. A 7-OH-MT concentration of 14.5 nmol/l may be a predictor of a good response to MT therapy.

Mortality Rates in Patients With Ankylosing Spondylitis With and Without Extraarticular Manifestations and Comorbidities: A Retrospective Cohort Study.

To examine mortality rates in hospitalized patients with ankylosing spondylitis (AS) and the association of extraarticular manifestations (EAMs) and comorbidities with mortality rates. This study was a retrospective, population-based cohort study using linked administrative data from patients with AS who were hospitalized (n = 1791) and patients in a matched comparison group (n = 8955). Mortality data for patients were obtained from the Western Australia Death Register. The presence of EAMs and comorbidities was identified from hospital records. Mortality rates were compared between the 2 groups using Cox proportional hazard models overall and stratified by a history of EAMs, comorbidities, and smoking status. Crude mortality rates were significantly higher among patients with AS than among patients in the comparison group (hazard ratio [HR] 1.85, 95% CI 1.62-2.12), with excess mortality in the AS group associated with cardiovascular disease (CVD; HR 5.32, 95% CI 3.84-7.35), cancer (HR 1.68, 95% CI 1.27-2.23), external causes (HR 3.92, 95% CI 2.28-6.77), and infectious diseases (HR 25.92, 95% CI 7.50-89.56). When patients were stratified by history of EAMs, CVD, and smoking, the risk of mortality was elevated in patients both with and without each risk factor. Among patients with AS, histories of CVD (HR 6.33, 95% CI 4.79-8.38), diabetes (HR 2.81, 95% CI 1.99-3.95), smoking (HR 1.49, 95% CI 1.18-1.89), and EAMs (HR 1.62, 95% CI 1.24-2.11) were associated with an increased risk of mortality. The presence of comorbidities, EAMs, and smoking contributes to an increased risk of all-cause mortality among patients with AS who are hospitalized compared to patients in the comparison group. These results support the need to prevent or reduce the occurrence of comorbidities and smoking in patients with AS.

Clinical and Epidemiological Aspects of Ankylosing Spondylitis Patients in a Single Center in Baghdad

Ankylosing spondylitis is a chronic inflammatory disease with axial involvement but also may present as a peripheral arthritis and extraarticular manifestations. Objective: To assess clinical aspects of ankylosing spondylitis patients and different associated demographic variables in Baghdad teaching hospital. Patients and methods: A cross-sectional study was carried out in Baghdad teaching hospital which includes 402 patients (≥ 18 years old) with a clinical diagnosis of AS according to Assessment of Spondylo Arthritis International Society for AS were involved in this study from June/2019 to June/2021. Demographic data and disease characteristics, presence of extra-articular manifestations (past and present) and measurement of disease activity was done by BASDAI, erythrocyte sedimentation rate (mm/h) and C-reactive protein (mg/L). In addition, HLAB27 typing was reported. Results: The age of onset for males was 24.87±8.8 and for females25.97±8.6 years, HLA typing HLA-B27 were 49.55% and 35.38% in males and females respectively and the association was found to be statistically significant (P. value =0.031). While family history was reported at 25.82% and 34.33% in males and females correspondingly. 75.07% of males compared to 71.38% of females were treated with Anti TNF therapy. Females had later onset of disease than males with lower percentage of HLA B27 positivity. Recommendation: more comprehensive assessment with advanced diagnostic and treatment standards.

Monocytes and Macrophages in Spondyloarthritis: Functional Roles and Effects of Current Therapies.

Spondyloarthritis (SpA) is a family of chronic inflammatory diseases, being the most prevalent ankylosing spondylitis (AS) and psoriatic arthritis (PsA). These diseases share genetic, clinical and immunological features, such as the implication of human leukocyte antigen (HLA) class I molecule 27 (HLA-B27), the inflammation of peripheral, spine and sacroiliac joints and the presence of extra-articular manifestations (psoriasis, anterior uveitis, enthesitis and inflammatory bowel disease). Monocytes and macrophages are essential cells of the innate immune system and are the first line of defence against external agents. In rheumatic diseases including SpA, the frequency and phenotypic and functional characteristics of both cell types are deregulated and are involved in the pathogenesis of these diseases. In fact, monocytes and macrophages play key roles in the inflammatory processes characteristics of SpA. The aim of this review is analysing the characteristics and functional roles of monocytes and macrophages in these diseases, as well as the impact of different current therapies on these cell types.

Extra-Articular Manifestations in Rheumatoid Arthritis - Predictors of Osteoporosis

Abstract In rheumatoid arthritis the extra-articular manifestations present a marker of disease severity and are accompanied by increased morbidity and mortality The aim of this paper is to study the relationship between extra-articular manifestations and osteoporosis in patients with rheumatoid arthritis. The study included 130 menopausal women diagnosed with rheumatoid arthritis. Bone mineral density was measured at lumbar spine and femoral by means of dual X-ray osteodensitometry. The obtained variables were analysed by bivariate analysis and logistic regression. The mean age was 62.77±7.51 years old. The medium duration of rheumatoid arthritis was 7.91±7.85 years, the frequency of extra-articular manifestations was 25.38%. The frequency of osteoporosis was 44.62%. The frequency of osteoporosis is statistically significantly higher in patients with rheumatoid arthritis who have extra-articular manifestations. The presence of extra-articular manifestations in patients with rheumatoid arthritis should draw attention to the need to determine bone mineral density.

Myeloperoxidase as an important predictor of cardiovascular risk in individuals with rheumatoid arthritis.

Rheumatoid arthritis is an inflammatory disease with joint manifestations. In the presence of extra-articular manifestations, the morbidity and severity of the disease increase. Glucocorticoid is used as a treatment and may result in side effects related to cardiovascular risk. This was a cross-sectional study including 59 volunteers with rheumatoid arthritis receiving treatment at a hospital of Campos Gerais that aimed to establish the relation between cardiovascular risk, glucocorticoid treatment and myeloperoxidase in these patients. Subjects were divided into two groups: using (n = 39) and without glucocorticoids (n = 20). They underwent clinical evaluation, physical examination and blood samples were taken. Statistical analysis was performed using Student's t test and Mann-Whitney test. Logistic regression was performed to assess the cardiovascular risk. The significance level was 5% (α = 0.05). Calculations were performed using the Statistical Package for the Social Science version 21.0. There has been a significant difference between groups in blood glucose values (p = 0.012), which can be explained by the different percentage of diabetic patients in the groups. When assessing cardiovascular risk using the predictors of glucocorticoid dose, time of glucocorticoid use, myeloperoxidase, and C-reactive protein together, these were responsible for significantly predicting this risk (p = 0.015). A significant relation between the predictor myeloperoxidase alone was also demonstrated (p = 0.037), it may be an important predictor of cardiovascular risk among individuals with rheumatoid arthritis.

P022 Genetic background predicts the extra-articular involvement in patients with enthesitis related arthritis

Abstract Background Enthesitis-related arthritis (ERA) represents 20% of all juvenile idiopathic arthritis subtype. Among the genetic risk factors for the development of ERA, HLA-B27 has been implicated as a major contributor. The frequency of HLA-B27 varies among population. HLA-B 27 status in ERA may influence the clinical phenotype and prognosis of the disease. The main objective of this study is to determine whether genetic background including HLA B27 and familial history of spondylarthritits (SpA) may influence the clinical features of ERA patients. Methods We conducted a retrospective study including patients with ERA, all fulfilling the International League of Associations for Rheumatology (ILAR) criteria. For all patients, we collected the following data: Age, family history of rheumatic inflammatory diseases, inflammatory bowel diseases (IBD), the presence of HLA-B27 antigen, the inflammatory biomarkers: Erythrocyte sedimentation rate (ESR) C-reactive protein (CRP), the disease activity assessed by morning stiffness, night awakenings, the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and the current treatment. We assessed, as well, the functional impact using the Bath Ankylosing Spondylitis Functional Index (BASFI) the Lequesne index. The population was divided into two groups: a group including patients positive to HLA-B27 antigen and/or with family history of rheumatic inflammatory diseases, psoriasis or inflammatorybowel diseases. The second group was defined as control group with patients negative to HLA-B27 antigen and without any family history of the diseases above. Results We included 40 ERA patients, mean age of onset 12,43 ± 3,003 years (6–16). The majority of them were male (n = 34). Twenty-eight patients had a genetic background. Among them, 7,5% of patients had a positive family history, 42,5% were positive to HLA-B27 antigen and 20% of them met both criteria. As shown in table 1, clinical manifestations were similar between the 2 groups. Enthesitis was more frequent in patients with HLAB27 without a significant difference. Regarding the disease activity, the number of night awakenings and the morning stiffness duration were comparable in the two groups. Six patients had a BASDAI score &amp;gt; 4 with no difference between the two groups. Extra-articular manifestations were present in 15 patients. Among them 14 had a genetic background, reaching the significance threshold with P = 0,013. We counted 8 cases of uveitis, one case of IBD, 5 cases of lung disease and 1 case of cardiac involvement. Inflammatory markers were higher in the group with familial history of SpA and/or positive HLAB27. Indeed, the mean ESR value was 42,73 vs 29.9, P = 0,01. There were no correlations between BASFI score and a positive genetic background (P = 0,283). Only one patient was put on biologics. He has no family history and is negative to HLA-B27 antigen. Conclusion The frequency of HLAB27 was in line with the literature data. The genetic background did not influence the disease activity or the functional impairment in our population. However, a positive correlation was found between a positive familial history of SpA, HLAB27, and the presence of extra-articular manifestations as well as with a higher ESR value.

Extra-Articular Manifestations and Comorbidities in Psoriatic Disease: A Journey Into the Immunologic Crosstalk.

Psoriatic arthritis (PsA) is a chronic inflammatory disease primarily affecting peripheral and axial joints, with the possible presence of extra-articular manifestations (EAMs), such as psoriasis, uveitis, and inflammatory bowel disease. Recently, the concept of psoriatic disease (PsD) has been proposed to define a systemic condition encompassing, in addition to joints and EAMs, some comorbidities (e.g., metabolic syndrome, type II diabetes, hypertension) that can affect the disease outcome and the achievement of remission. EAMs and comorbidities in PsA share common immunopathogenic pathways linked to the systemic inflammation of this disease; these involve a broad variety of immune cells and cytokines. Currently, various therapeutics are available targeting different cytokines and molecules implicated in the inflammatory response of this condition; however, despite an improvement in the management of PsA, comprehensive disease control is often not achievable. There is, therefore, a big gap to fill especially in terms of comorbidities and EAMs management. In this review, we summarize the clinical aspects of the main comorbidities and EAMs in PsA, and we focus on the immunopathologic features they share with the articular manifestations. Moreover, we discuss the effect of a diverse immunomodulation and the current unmet needs in PsD.

Development of a risk indicator score for the identification of interstitial lung disease in patients with rheumatoid arthritis

BackgroundClinically evident interstitial lung disease (ILD) affects 10%–42% of RA patients with prognostic implications. The aim of this study was to discern which factors are associated with the presence of ILD in RA patients and to develop a score that could help to stratify the risk of having ILD in RA patients. MethodsCase–control study. We included RA patients recruited from ILD and rheumatology clinics. We retrieved the following data: gender, age, presence of extra articular manifestations, disease activity scores, antibodies status, ESR, and medication use. Multivariate logistic regression was performed. A risk indicator score was developed. ResultsOf 118 patients included in this study, 52 (44%) had RA-ILD (cases) and 66 (56%) had RA without ILD (controls). Twenty-six patients were male (22%), the mean age was 56.6±15.6 years. Five variables were significantly associated with the presence of ILD: male gender, smoking, extraarticular manifestations, a CDAI score>28, and ESR>80mm/h. The AUC of the final model curve was 0.86 (95%CI 0.79–0.92). Two potential cut-off points of the risk indicator score were chosen: a value of 2 points showed a sensitivity of 90.38% and a specificity of 63.64%, while a value of 4 points showed a sensitivity of 51.9% and a specificity of 90.9%. ConclusionThis study identified risk factors that could help identify which RA patients are at risk of having ILD through the development of a risk indicator score. This score needs to be validated in an independent cohort.

Features of dyslipidemia and its influence on endothelium functional state in patients with rheumatoid arthritis and arterial hypertension

Purpose of the study. Was to identify the features of blood lipid spectrum and endothelium functional state in patients with rheumatoid arthritis (RA) and arterial hypertension (AH).&#x0D; Materials and methods. 83 patients were examined (40 with RA combined with AH, 23 with RA and 20 with AH). The blood lipid spectrum and endothelial function were studied in all patients.&#x0D; Results. The analysis of blood serum lipid parameters demonstrated that in patients with RA, regardless of the presence of AH, there was a significant increase of proatherogenic lipid profile parameters in comparison with those in healthy subjects. It was shown, that lower concentrations of high-density lipoproteins and higher atherogenic coefficient indices was a characteristic feature of the lipid profile in RA patients both with and without AH – in contrast to the same parameters of the lipid spectrum in patients with AH without RA. In the groups of patients with RA a significant increase of the brachial artery diameter at rest and decreased indices of endothelium-dependent vasodilation and endothelium-independent vasodilation were revealed. Subjects with RA in combination with AH had significantly lower indices according to the tests with both reactive hyperemia and nitroglycerin, while in patients with RA without AH, only NG-test was significantly lower.&#x0D; Conclusion. Dyslipidemia of atherogenic type and endothelial dysfunction develops at the initial stages of rheumatoid process and depends on the activity of the inflammatory process, the presence of extra-articular manifestations and rheumatoid factor seropositivity.

Extra-Articular Manifestations in Rheumatoid Arthritis-Predictors of Nonvertebral Fractures

Abstract Introduction: In rheumatoid arthritis the extra-articular manifestations present a marker of disease severity and are accompanied by increased morbidity and mortality. Objectives: The aim of this paper is to study the relationship between extra-articular manifestations and nonvertebral fractures in patients with rheumatoid arthritis. Methods: The study included 130 menopausal women diagnosed with rheumatoid arthritis. Bone mineral density was measured at lumbar spine and femoral by means of dual X-ray osteodensitometry. Nonvertebral fractures such as femur, humerus, or forearm fractures were diagnosed through questioning the subjects The obtained variables were analyzed by bivariate analysis and logistic regression. Results: The mean age was 62.77±7.51 years old. The medium duration of rheumatoid arthritis was 7.91±7.85 years, the frequency of extra-articular manifestations was 25.38%. The frequency of nonvertebral fractures was 19.23%. The frequency of nonvertebral fractures is statistically significantly higher in patients with rheumatoid arthritis who have extra-articular manifestations (36.36% vs 13.40%, p: 0.008). Conclusions: In the presence of extra-articular manifestations in patients with rheumatoid arthritis, primary prevention measures are required for nonvertebral fractures.

Functional Disability and Its Determinants in Ecuadorian Patients with Rheumatoid Arthritis.

IntroductionDisability in RA is associated with loss of workdays, greater use of health resources and a higher prevalence of depression. The purpose of this study was to determine the prevalence of functional disability and the factors associated with it.MethodsA cross-sectional study was carried out during January–June 2019 at a rheumatology clinic in the city of Guayaquil. Patients with pre-established RA were included. Functional disability was measured using the HAQ-DI. Data were analyzed using the statistical program SPSS v22. We compared characteristics between patients with and without disability using Student’s t-test and chi-square. A multiple logistic regression model for functional disability was made.ResultsWe included 395 patients, 87.8% female and 12.2% male with a mean age of 51.4±12 years and mean duration of disease 13.8±7 years. Most patients had extra-articular manifestations (80.8%) and comorbidities (81.3%). The mean HAQ-DI was 0.8±0.9, with a prevalence of disability of 26.6%. We found a statistically significant relationship between disability and female sex (p=0.018), age (p=0.020), presence of extra-articular manifestations (p=0.008), myalgia (p<0.001) and fatigue (p<0.001). In addition, patients with disabilities had a lower employment rate (26.7%) compared to those without disability (45.5%, p=0.001). In the multivariate logistic analysis, only depression (p=0.029), diabetes (p=0.003), SJC (p=0.001) and VAS of pain (p=0.004) were significantly related to functional disability.ConclusionDisability affects a quarter of patients with RA. Among the determinants of disability, we found female sex, older age, grade of pain, inflammatory markers and the level of disease activity.

Prevalence and associated factors of subclinical atherosclerosis in rheumatoid arthritis at the university hospital of Kinshasa

BackgroundRheumatoid arthritis (RA) is associated with a 5 to 10 years reduction in life expectancy due to premature atherosclerosis. This reduction is the consequence of traditional cardiovascular risk factors (TCRF) as well as systemic inflammation. The aim of the present study was to describe the prevalence and factors associated with subclinical atherosclerosis in RA at the University Hospital of Kinshasa (UHK).MethodsPatients with a diagnosis of RA based on the 2010 ACR/EULAR criteria were included in this cross-sectional study from 1 June 2014 to 31 May 2015 at the UHK. RA disease activity was measured using the DAS28-ESR. Active RA was defined by a DAS 28 > 2.6. Severe RA was defined by the presence of extra-articular manifestation, joint erosions on X-rays or HAQ ≥0.5. An assessment of subclinical atherosclerosis was performed by the measurement of the carotid intima-media thickness (cIMT) using two-dimensional ultrasonography. Subclinical atherosclerosis was defined by a cIMT ≥0.9 mm. A diagnosis of atheroma plaque was retained when the cIMT was ≥1.5 mm. The association between subclinical atherosclerosis and potential risk factors was modeled using logistic regression analysis.ResultsWe recruited 75 patients. The average age was 51.8 ± 14.6 years, with a sex ratio F/M of 4. The prevalence of subclinical atherosclerosis was 32%. In logistic regression being a woman of ≥55 years old (aOR 10.6, 95% CI [2.087–53.82], p = 0.028), DAS28-ESR > 2.6 (aOR 3.5,95% CI [1.55–10.38], p = 0.044), severe RA (aOR 32.6,95% CI [1.761–60.37],p = 0.035), high blood pressure (aOR 22.4,95% CI [5.04–99.41], p = 0.005) and obesity (aOR 32.3, 95% CI [2.606–40.73], p = 0.026) emerged as factors associated with subclinical atherosclerosis.ConclusionSubclinical atherosclerosis is common in RA patients attending the UHK. It appears to be associated with RA disease activity and severity apart from traditional cardiovascular risk factors. These results suggest that early management of subclinical atherosclerosis targeting remaining RA disease activity and cardiovascular risk factors could slow down progression to clinical cardiovascular disease.
