In the present study, we aimed to report our experience with rituximab (RTX) in the treatment of patients with ILD associated with AD (AD-ILD) at a single center. For this purpose, clinical ...characteristics, radiological findings, and pulmonary function tests (PFTs) of RTX-treated AD-ILD-patients seen from May 2016 until March 2020 at a referral center for individuals with ILD were retrospectively reviewed. Additionally, an updated literature review was conducted. A total of 26 patients (mean age 58.3 ± 11.1 years at ILD diagnosis) was included. The most common ADs related to ILD were systemic sclerosis, idiopathic inflammatory myositis (including anti-synthetase syndrome) and rheumatoid arthritis. Non-specific interstitial pneumonia (n = 12) and usual interstitial pneumonia (n = 11) were the predominant radiological patterns. The sustained improvement in PFTs was observed from the start of RTX, with a statistically significant increase in DLCO from basal to one year after RTX (mean + 4.2%, p = 0.024). Overall, there were no differences when comparing PFT outcome according to the radiological pattern or the specific type of AD. In conclusion, RTX constitutes a good therapeutic option to preserve lung function in patients with AD-ILD, regardless of the radiological pattern or the underlying AD.
To compare the efficacy of TNF inhibitors (adalimumab (ADA) and infliximab (IFX)) vs tocilizumab (TCZ) in patients with refractory cystoid macular edema (CME) due to Behçet's disease (BD).
...Multicenter study of patients with BD-associated CME refractory to conventional and/or biological immunosuppressive drugs. From a cohort of 177 patients treated with anti-TNF and 14 patients treated with TCZ, we selected those with CME at baseline. We analyzed the evolution of macular thickness (main outcome), best-corrected visual acuity (BCVA) and intraocular inflammation (Tyndall and vitritis) from baseline up to 4 years in the 3 groups mentioned.
49 patients and 72 eyes with CME were included. ADA was used in 25 patients (40 eyes), IFX in 15 (21 eyes) and TCZ in 9 (11 eyes). No statistically significant baseline differences were observed between the 3 groups except for a lower basal BCVA in TCZ group and a higher basal degree of intraocular inflammation in ADA group. Most patients from all groups had received several conventional immunosuppressive drugs. In addition, most patients in the group of TCZ had also received anti-TNF agents. Biological therapy was used in monotherapy (n=8) or combined with conventional immunosuppressive drugs (n=41). Macular thickness progressively decreased in the 3 groups, with no signs of CME after 1 year of treatment. Similarly, BCVA improvement and inflammatory intraocular remission was achieved in all groups.
Refractory CME associated with BD uveitis can be effectively treated either with ADA, IFX or TCZ. Furthermore, TCZ is effective in patients resistant to anti-TNF therapy.
Osteopontin (OPN) is a glycoprotein involved in Th1 and Th17 differentiation, and inflammation and tissue remodeling. OPN is a biomarker of disease activity in patients with autoimmune inflammatory ...conditions. This study aimed to assess the diagnostic and prognostic value of OPN in interstitial lung diseases (ILDs). Between May 2016 and October 2019, 344 patients with ILD were recruited at the Hospital Universitario Marqués de Valdecilla (Spain) and were prospectively followed-up. This study involved the determination of OPN serum levels by ELISA and OPN RNA expression quantified using qPCR. Six genetic polymorphisms in OPN (rs28357094, rs2853749, rs2853750, rs11728697, rs7695531, and rs1126616) were genotyped using TaqMan assays. OPN serum levels were also assessed in 140 healthy controls. OPN serum levels (median interquartile range) were significantly higher in ILD patients than in controls (1.05 0.75-1.51 ng/mL versus 0.81 0.65-0.98 ng/mL in healthy controls;
< 0.01). OPN serum levels were inversely correlated with the forced vital capacity. OPN serum levels were also higher in ILD patients who died or underwent lung transplantation when compared with the remaining ILD patients (1.15 0.80-1.72 ng/mL versus 0.99 0.66-1.32 ng/mL;
= 0.05). Survival worsened in ILD patients with OPN > 1.03 ng/mL at 1, 3, and 5 years. No statistically significant differences in the genetic frequencies of
polymorphisms or the RNA expression were found among the different ILD groups. Elevated levels of OPN in the serum may be a useful indicator in identifying patients with ILD who are more likely to experience poor outcomes.
To determine whether giant cell arteritis (GCA) patients with the typical pattern of cranial ischemic manifestations and those with the extracranial large-vessel-vasculitis (LVV)-GCA phenotype ...exhibit different HLA-DRB1 association.
178 biopsy-proven GCA patients who had cranial ischemic features but no LVV manifestations, 100 patients with LVV-GCA without cranial ischemic manifestations and 486 ethnically matched healthy controls were recruited. All patients and controls were Spanish of European ancestry. We compared HLA-DRB1 phenotype frequencies between the three groups.
Both GCA subgroups had well-differentiated clinical features. Patients with LVV-GCA were younger (68.0 ± 10.0 years versus 74.0 ± 10.4 years; p < 0.01) and presented more commonly with polymyalgia rheumatica symptoms (81% versus 39.3%; p < 0.01) than those with the classic cranial GCA phenotype. HLA-DRB1*04 phenotype frequency was significantly increased in patients with classic cranial GCA compared to controls (42.1% versus 23.5%, respectively; p < 0.01; odds ratio-OR 95% confidence interval-CI = 2.38 1.62–3.47). This association was mainly due to the HLA-DRB1*04:01 allele (20.8% versus 5.3%, respectively; p < 0.01; OR 95% CI = 4.64 2.63–8.26). HLA-DRB1*04 association was also observed in LVV-GCA patients when compared to controls (46.0% versus 23.5%, respectively; p < 0.01; OR 95% CI = 2.78 1.73–4.44). Similar to cranial GCA, the association was also mainly due to the HLA-DRB1*04:01 allele (19.0% versus 5.3%, respectively; p < 0.01; OR 95% CI = 4.15 2.06–8.19). Cranial and LVV-GCA patients did not exhibit HLA-DRB1 allele differences.
Cranial and extracranial LVV-GCA share similar HLA-DRB1 association.
Psoriatic arthritis (PsA) is associated with several comorbidities, including among others an increased risk of cardiovascular (CV) disease, atherosclerosis, metabolic syndrome, hypertension ...dyslipidemia, and diabetes. The purpose of the present study was to determine how the number of CV risk factors correlates with disease related data such as disease activity.
Cross-sectional study that encompassed 305 patients who fulfilled the CASPAR criteria for PsA were assessed for lipid profile, disease activity measurements, and the presence of six traditional CV risk factors (diabetes mellitus, dyslipidemia, hypertension, obesity, chronic kidney disease, and smoking status). A multivariable regression analysis, adjusted for age, sex, and disease duration, was performed to evaluate if the number of classic CV risk factors was independently related with specific features of the disease, including disease activity.
Disease duration was found to be higher, after adjustment for age and sex, in patients with 1 or 2, and 3 or higher CV factors, compared to those patients without CV risk factors. Similarly, DAPSA (Disease Activity in PSoriatic Arthritis score) was found to be independently upregulated in patients with a higher number of CV risk factors. In this sense, as DAPSA score increases the odds ratio (OR) of having 1 or 2 (OR 1.12 (95% confidence interval (CI) 1.03-1.21),
= 0.010), and 3 or higher (OR 1.15 (95% CI 1.04-1.26),
= 0.004) CV factors was significantly higher compared to no CV risk factors category. This was independently found after adjustment for age, sex, and disease duration.
: PsA patients with a higher number of CV risk factors exhibit an upregulated disease activity compared to those without them. This is independent of disease duration and other demographics factors.
The risk of cardiovascular (CV) disease and mortality is increased by rheumatoid arthritis (RA). However, data on how RA patients perceive their own CV risk and their adherence to CV prevention ...factors are scarce. We conducted an observational study on 266 patients with RA to determine whether the perceived CV risk correlates to the objective CV risk, and if it influences their compliance with a Mediterranean diet and physical exercise. The objective CV risk was calculated according to the modified European League Against Rheumatism (EULAR) Systematic Coronary Risk Evaluation (SCORE). The perceived CV risk did not correlate to the objective CV risk. The correlation was even lower when carotid ultrasound was used. Notably, 64.62% of patients miscalculated their CV risk, with 43.08% underestimating it. Classic CV risk factors, carotid ultrasound markers and ESR and CRP showed significant correlation with the objective CV risk. However, only hypertension and RA disease features showed association with the perceived CV risk. Neither the objective CV risk nor the perceived CV risk were associated with the accomplishment of a Mediterranean diet or physical activity. In conclusion, RA patients tend to underestimate their actual CV risk, giving more importance to RA features than to classic CV risk factors. They are not concerned enough about the beneficial effects of physical activity or diet.
Tofacitinib (TOF) is the first Janus kinase (JAK) inhibitor approved for psoriatic arthritis (PsA). It has shown efficacy in patients refractory to anti-tumor necrosis factor-α in randomized ...controlled trials (RCTs). Our aim was to assess efficacy and safety of TOF in clinical practice.
This was an observational, open-label multicenter study of PsA patients treated with TOF due to inefficacy or adverse events of previous therapies. Outcome variables were efficacy, corticosteroid dose-sparing effect, retention rate, and safety. A comparative study of clinical features between our cohort of patients and those from the OPAL Beyond trial was performed.
There were 87 patients (28 women/59 men), with a mean age of 52.8 ± 11.4 years. All patients were refractory to biologic disease-modifying antirheumatic drugs (DMARDs) and/or to conventional synthetic DMARDs plus apremilast. TOF was started at 5 mg twice daily after a mean follow-up of 12.3 ± 9.3 years from PsA diagnosis. At first month, Disease Activity Score in 28 joints based on erythrocyte sedimentation rate (DAS28-ESR) decreased from median 4.8 (IQR 4.1-5.4) to 3.7 (IQR 2.8-4.7,
< 0.01), Disease Activity Index for Psoriatic Arthritis from median 28 (IQR 18.4-34.1) to 15.5 (IQR 10.1-25.7,
< 0.01), and C-reactive protein from median 1.9 (IQR 0.3-5.0) to 0.5 (IQR 0.1-2.2) mg/dL (
< 0.01). Also, TOF led to a significant reduction in prednisone dose. Mild adverse effects were reported in 21 patients (24.13%), mainly gastrointestinal symptoms. TOF retention rate at Month 6 was 77% (95% CI 65.2-86.3). Patients in clinical practice were older with longer disease duration and received biologic agents more commonly than those in the OPAL Beyond trial.
Data from clinical practice confirm that TOF seems to be effective, rapid, and relatively safe in refractory PsA despite clinical differences with patients in RCTs.
Early diagnosis of interstitial lung disease (ILD) associated with rheumatoid arthritis (RA) constitutes a challenge for the clinicians. Pulmonary vasculopathy is relevant in the development of ...interstitial lung disease. Accordingly, we aimed to explore the role of vascular cell adhesion molecule-1 (VCAM-1), monocyte chemoattractant protein-1 (MCP-1) and asymmetric dimethylarginine (ADMA), key molecules in the vasculopathy, as potential biomarkers of pulmonary fibrosis in RA-ILD
.
We included 21 RA-ILD
patients and two comparative groups: 25 RA-ILD
patients and 21 idiopathic pulmonary fibrosis (IPF) patients. Serum levels of the molecules were determined by ELISA, and mRNA expression was quantified by qPCR.
VCAM-1, MCP-1 and ADMA serum levels were increased in RA-ILD
patients in relation to RA-ILD
and IPF patients. Additionally, RA-ILD
patients exhibited increased
(gene encoding MCP-1) and decreased
(gene related to ADMA synthesis) mRNA expression in relation to RA-ILD
patients. A lower expression of
,
, and
was observed in RA-ILD
patients when compared with those with IPF. Furthermore, MCP-1 serum levels and
mRNA expression were positively correlated with RA duration, and ADMA serum levels were positively associated with C-reactive protein in RA-ILD
patients.
Our study suggests that VCAM-1, MCP-1 and ADMA could be considered as useful biomarkers to identify ILD in RA patients, as well as to discriminate RA-ILD
from IPF, contributing to the early diagnosis of RA-ILD
.
Polymyalgia rheumatica (PMR) is a common inflammatory disease found in people older than 50 years of Northern European descent. It is characterized by pain and stiffness in the shoulders, arms, hips, ...and neck. Relapses are common in patients with PMR.
This review describes when and how relapses occur in patients with PMR. Potential predisposing factors associated with relapses and management are also discussed. An extensive literature search on the PubMed database was conducted for publications on 'polymyalgia rheumatica' AND 'relapses' AND 'risk factors'.
Relapses are common in PMR being observed in approximately half of the patients. They often occur when the dose of prednisone is below 5-7.5 mg/day. The speed of glucocorticoid tapering is considered to be the main factor influencing the development of relapses in isolated PMRs. In addition, a genetic component may favor the presence of relapses in isolated PMRs. HLA-DRB1*0401 alleles were associated with an increased risk of relapse. An implication of the IL-6 promoter -174 G/C polymorphism and the GG241 ICAM-1 genotype was also reported. With regard to serological biomarkers, elevated levels of angiopoietin-2 were associated with an unfavorable course of PMR. Methotrexate and anti-IL6 receptor antibody tocilizumab may be required in PMR patients with multiple relapses.
Interstitial lung disease (ILD) may occur in patients with a rheumatic autoimmune disease (AD), increasing their risk of morbidity and mortality. However, little is known about the prevalence of AD ...in patients diagnosed with an ILD. In this prospective study, we determined the spectrum of ILD associated with AD (AD-ILD) among patients sent for assessment to a single clinic of ILD and lung transplantation from a referral center between May 2016 and December 2019. ILD diagnosis was made by pneumologists based on clinical and radiological findings and pulmonary function test abnormalities. All patients with ILD were also assessed by experienced rheumatologists. During the period of assessment, 338 patients were diagnosed with ILD. Among them, 32.8% fulfilled definitions for an AD. Most cases with AD-ILD had a diagnosis of rheumatoid arthritis (27.0%), systemic sclerosis (26.1%) or anti-synthetase syndrome (17.1%). Interestingly, 18% of the patients with AD-ILD were diagnosed as having an interstitial pneumonia with autoimmune features. Antinuclear antibodies and non-specific interstitial pneumonia were the most frequent positive autoantibodies and radiological pattern found in AD-ILD patients, respectively. In conclusion, our study indicates that a high number of ILD patients have a related AD. Consequently, close collaboration among rheumatologists and pneumologists is needed.
