Eight-year survival study of first-line tumour necrosis factor α inhibitors in rheumatoid arthritis: real-world data from a university centre registry

Predictors of Drug Retention and Survival Rate of bDMARDs in Rheumatoid Arthritis: A Four-Year Real-Life Tunisian Experience

Introduction

This study aims to investigate the efficacy and tolerance of biologic disease-modifying anti-rheumatic drug (bDMARDs) in the current management of rheumatoid arthritis (RA) by identifying the retention time and survival rate of bDMARDs.

Materials and Methods

We conducted a retrospective cohort study including Tunisian patients initiating bDMARD treatment between 2016 and 2018 whose data were collected from the National Health Insurance Fund (NHIF). The NHIF is the national office which organises and centralises patients under bDMARDs from all over the country. Retention and survival rate of bDMARDs at 48 months were analysed using Kaplan-Meier survival curves and compared using the log-rank test. Survival factor analysis was performed using Cox regression.

Results

Three hundred seventy-four patients, aged 55.5±12.5years [20-90], (87.2%women), were included. The mean duration of RA was 11.7±6.7 years [2-41]. The mean disease activity score (DAS)28 at initiation of the first bDMARD was 6.01±0.89 [5.37-6.5]. This first bDMARD induced low disease activity (LDA) in 55% of cases. Remission was observed in 28% of patients. The highest LDA and remission rates were observed with Tocilizumab (70.8% and 33.3% of cases, respectively). LDA and remission were achieved within a mean of 45 weeks [26-88] and 72 weeks [31-117] respectively. The 48-month first-line survival rate was 55.9%. Retention time was 41.7 months, 95%CI [39.47-43.91]. Presence of rheumatoid factors, co-prescription of methotrexate, and good initial therapeutic response were factors influencing better survival of bDMARDs (p<0.01). Glucocorticoid use predicted poorer survival (p<10-3). The first bDMARD was interrupted in 39% of cases. Ineffectiveness was the most common cause of treatment cessation (52.7%).

Conclusion

This real-life study of the Tunisian population allowed us to establish the factors that can influence the survival and retention rates of bDMARDs.

Etanercept in Axial Spondyloarthritis, Psoriatic Arthritis, and Plaque Psoriasis: Real-World Outcome Data from German Non-interventional Study ADEQUATE

INTRODUCTION

For chronic diseases such as axial spondyloarthritis (axSpA), psoriatic arthritis (PsA), and plaque psoriasis (PsO), treatment goals include remission or at least low disease activity (LDA) by 12 weeks. Improvements in symptoms such as pain and fatigue should also be treatment goals.

METHODS

ADEQUATE was a German, prospective, non-interventional study to evaluate the proportion of patients with rheumatoid arthritis, PsA, axSpA, or PsO who, in routine clinical practice, benefit from the continuation of treatment with etanercept (ETN) beyond 12 weeks, even when their treatment goals have not yet been reached. Patient-reported outcomes (PROs) and changes in concomitant glucocorticoid use were also recorded. This article focuses on results for patients with axSpA and PsA; data for patients with PsO are described briefly.

RESULTS

In total, 305, 254, and 70 patients with axSpA, PsA, and PsO, respectively, were included. Rates of remission at week 12 and week 24, respectively, were 19% and 18% for axSpA, 38% and 51% for PsA, and 7% and 19% for PsO. Rates of LDA at week 12 and week 24, respectively, were 39% and 45% for axSpA, 50% and 60% for PsA, and 34% and 51% for PsO. Extending treatment up to 52 weeks was associated with stable rates of or further increases in remission and LDA rates. Improvements in pain, fatigue, and depression (axSpA, PsA, and PsO) and reductions in concomitant glucocorticoid use (axSpA and PsA) were observed. No new safety signals were detected.

CONCLUSION

These findings confirm the effectiveness and safety of ETN in routine clinical practice for several indications and highlight potential benefits of continuing ETN treatment in patients who have not reached their treatment goals after 12 weeks. Additional benefits included improvements in PROs and reduction of concomitant glucocorticoids.

Characteristic analysis of adverse reactions of five anti-TNFɑ agents: a descriptive analysis from WHO-VigiAccess

Introduction: Tumor necrosis factor (TNF) inhibitors (adalimumab, infliximab, etanercept, golimumab, and certolizumab pegol) have revolutionized the treatment of severe immune-mediated inflammatory diseases, including rheumatoid arthritis, Crohn's disease, psoriatic arthritis, ankylosing spondylitis, and ulcerative colitis. This study assessed adverse drug reactions (ADRs) after the use of TNFα inhibitors in VigiAccess of the World Health Organization (WHO) and compared the adverse reaction characteristics of five inhibitors to select the drug with the least risk for individualized patient use. Methods: The study was a retrospective descriptive analysis method in design. We sorted out five marketed anti-TNFα drugs, and their ADR reports were obtained from WHO-VigiAccess. Data collection included data on the age groups, sex, and regions of patients worldwide covered by ADR reports, as well as data on disease systems and symptoms caused by ADRs recorded in annual ADR reports and reports received by the WHO. By calculating the proportion of adverse reactions reported for each drug, we compared the similarities and differences in adverse reactions for the five drugs. Results: Overall, 1,403,273 adverse events (AEs) related to the five anti-TNFα agents had been reported in VigiAccess at the time of the search. The results show that the 10 most commonly reported AE manifestations were rash, arthralgia, rheumatoid arthritis, headache, pneumonia, psoriasis, nausea, diarrhea, pruritus, and dyspnea. The top five commonly reported AE types of anti-TNFα drugs were as follows: infections and infestations (184,909, 23.0%), musculoskeletal and connective tissue disorders (704,657, 28.6%), gastrointestinal disorders (122,373, 15.3%), skin and subcutaneous tissue disorders (108,259, 13.5%), and nervous system disorders (88,498, 11.0%). The preferred terms of myelosuppression and acromegaly were obvious in golimumab. Infliximab showed a significantly higher ADR report ratio in the infusion-related reaction compared to the other four inhibitors. The rate of ADR reports for lower respiratory tract infection and other infections was the highest for golimumab. Conclusion: No causal associations could be established between the TNFα inhibitors and the ADRs. Current comparative observational studies of these inhibitors revealed common and specific adverse reactions in the ADR reports of the WHO received for these drugs. Clinicians should improve the rational use of these high-priced drugs according to the characteristics of ADRs.

Drug-survival profiling of second-line biologic therapy in rheumatoid arthritis: Choice of another tumour necrosis factor inhibitor or a biologic of different mode of action?

OBJECTIVES

To assess the best choice of second-line therapy between tumour necrosis factor-inhibitor (TNFi) and biologics of different-mode-of-action (BDMA-rituximab/tocilizumab/abatacept) in rheumatoid arthritis (RA) by evaluating drug-survival following discontinuation of the first-line TNFi.

METHODS

This retrospective drug-survival study was performed across two different hospitals by conventional-statistics and machine-learning approach.

RESULTS

From a total of 435 patients, 213 (48.9%; TNFi = 122, BDMA = 91) discontinued their second-line biologic {median drug-survival: TNFi, 27 months [95% confidence interval (95%CI) 22-32] vs BDMA, 37 months (95%CI 32-52)}. As a second-line biologic, BDMA was likely to reduce the risk of treatment-discontinuation [hazard-ratio (HR) 0.63, 95%CI 0.48-0.83] compared to TNFi, but only in seropositive-patients (HR 0.52, 95%CI 0.38-0.73), not in seronegative-RA. Drug-survival benefit of BDMA over TNFi was not observed if the seropositive-patients were previously exposed to monoclonal-TNFi (HR 0.77, 95%CI 0.49-1.22) versus soluble-TNFi (etanercept/biosimilars) or if the first-line TNFi was terminated within 23.9 months of initiation (HR 0.97, 95%CI 0.56-1.68).

CONCLUSIONS

BDMA, as a second-line biologic, is more likely to be sustained in seropositive-patients, particularly without prior exposure to monoclonal-TNFi. The drug-survival benefit of BDMA was not observed in seronegative-patients or if the first-line TNFi was stopped within 2 years.

Systemic sclerosis and vaccinations: a three-year register-based cohort study about vaccination rate and uptake from Liguria referral center, northwest Italy

Patients with diffused Systemic Sclerosis (dSSc) are more subject to severe respiratory complications with higher rates of intensive care unit (ICU) admission. Vaccination represents the most effective means of prevention and care for frail patients, such as SSc patients, preventing infections, reducing mortality and morbidity, and granting a better quality of life. Both vaccinations against seasonal influenza and Streptococcus pneumoniae are currently recommended by the European League Against Rheumatism (EULAR) guidelines on vaccination. The aim of this study is to give an updated analysis on S. pneumoniae and seasonal influenza vaccination coverage in a cohort of 91 patients with SSc and to investigate demographic and clinical variables significantly related to vaccine acceptance. The correlation between vaccine administration and other factors was investigated using a binomial logistic regression to evaluate the adjusted odds ratio (aOR). The patients followed up in this study reached higher percentages than the general population, passing the 75% target for both influenza and anti-pneumococcal vaccinations and reaching for influenza vaccine coverage rates of 83.8% for subjects undergoing immunosuppressive therapies and 88.9% for elderly subjects. For the latter group, it is important to emphasize the strong correlation between older age groups and vaccination acceptance.

Promising Strategies for Transdermal Delivery of Arthritis Drugs: Microneedle Systems

Arthritis is a general term for various types of inflammatory joint diseases. The most common clinical conditions are mainly represented by rheumatoid arthritis and osteoarthritis, which affect more than 4% of people worldwide and seriously limit their mobility. Arthritis medication generally requires long-term application, while conventional administrations by oral delivery or injections may cause gastrointestinal side effects and are inconvenient for patients during long-term application. Emerging microneedle (MN) technology in recent years has created new avenues of transdermal delivery for arthritis drugs due to its advantages of painless skin perforation and efficient local delivery. This review summarizes various types of arthritis and current therapeutic agents. The current development of MNs in the delivery of arthritis drugs is highlighted, demonstrating their capabilities in achieving different drug release profiles through different self-enhancement methods or the incorporation of nanocarriers. Furthermore, the challenges of translating MNs from laboratory studies to the clinical practice and the marketplace are discussed. This promising technology provides a new approach to the current drug delivery paradigm in treating arthritis in transdermal delivery.

Janus kinase versus TNF inhibitors: where we stand today in rheumatoid arthritis

INTRODUCTION

In recent decades, Rheumatoid arthritis (RA) treatment landscape has evolved with the induction of new biological and targeted therapies that provide significant therapeutic benefits in patients with sustained disease.

AREAS COVERED

Tumor necrosis factor inhibitors (TNFi) were the first biologics used in the treatment of RA. Although they present a significant efficacy, an insufficient response of some patients led to further research and discovery of targeted therapies, such as Janus kinase inhibitors (JAKi), which act at a molecular level, regulating many cytokines. Clinical benefits have been seen with both TNFi and JAKi as monotherapy and combined with conventional synthetic disease-modifying antirheumatic drugs. Still, some significant side effects have been reported with JAKi, and several questions remain about their safety and selectivity in action. This review summarizes the current knowledge on the mechanism of action, the clinical efficacy, and safety of TNFi vs. JAKi.

EXPERT OPINION

TNFi and JAKi are particularly useful in treating inflammatory arthropathies. Both drug categories are recommended by ACR and EULAR institutions in RA patients suffering from moderate to severe disease. Safety data in long-term studies are required to determine the optimal benefit to the risk profile of JAKi use.

The Risk of Adverse Effects of TNF-α Inhibitors in Patients With Rheumatoid Arthritis: A Network Meta-Analysis

Objectives

To evaluate the safety of each anti-TNF therapy for patients with rheumatoid arthritis (RA) and then make the best choice in clinical practice.

Methods

We searched PUBMED, EMBASE, and the Cochrane Library. The deadline for retrieval is August 2021. The ORs, Confidence Intervals (CIs), and p values were calculated by STATA.16.0 software for assessment.

Result

72 RCTs involving 28332 subjects were included. AEs were more common with adalimumab combined disease-modifying anti-rheumatic drugs (DMARDs) compared with placebo (OR = 1.60, 95% CI: 1.06, 2.42), DMARDs (1.28, 95% CI: 1.08, 1.52), etanercept combined DMARDs (1.32, 95% CI: 1.03, 1.67); certolizumab combined DMARDs compared with placebo (1.63, 95% CI: 1.07, 2.46), DMARDs (1.30, 95% CI: 1.10, 1.54), etanercept combined DMARDs (1.34, 95% CI: 1.05, 1.70). In SAEs, comparisons between treatments showed adalimumab (0.20, 95% CI: 0.07, 0.59), etanercept combined DMARDs (0.39, 95% CI: 0.15, 0.96), golimumab (0.19, 95% CI: 0.05, 0.77), infliximab (0.15, 95% CI: 0.03,0.71) decreased the risk of SAEs compared with golimumab combined DMARDs. In infections, comparisons between treatments showed adalimumab combined DMARDs (0.59, 95% CI: 0.37, 0.95), etanercept (0.49, 95% CI: 0.28, 0.88), etanercept combined DMARDs (0.56, 95% CI: 0.35, 0.91), golimumab combined DMARDs (0.51, 95% CI: 0.31, 0.83) decreased the risk of infections compared with infliximab combined DMARDs. No evidence indicated that the use of TNF-α inhibitors influenced the risk of serious infections, malignant tumors.

Conclusion

In conclusion, we regard etanercept monotherapy as the optimal choice for RA patients in clinical practice when the efficacy is similar. Conversely, certolizumab + DMARDs therapy is not recommended.

Effectiveness of Etanercept in Rheumatoid Arthritis: Real-World Data from the German Non-interventional Study ADEQUATE with Focus on Treat-to-Target and Patient-Reported Outcomes

BACKGROUND

For rheumatoid arthritis (RA), the treat-to-target concept suggests attaining remission or at least low disease activity (LDA) after 12 weeks.

OBJECTIVES

This German, prospective, multicenter, non-interventional study aimed to determine the proportion of patients with RA who achieved their treat-to-target aim after 12 and 24 weeks of etanercept (ETN) treatment in a real-life setting, as opposed to patients achieving their therapeutic target at a later timepoint (week 36 or 52).

METHODS

A total of 824 adults with a confirmed diagnosis of RA without prior ETN treatment were included. Remission and LDA were defined as DAS28 < 2.6 and DAS28 ≤ 3.2, respectively.

RESULTS

The proportion of patients achieving remission was 24% at week 12 and 31% at week 24. The proportion of patients achieving LDA was 39% at week 12 and 45% at week 24. The proportion of patients achieving remission or LDA further increased beyond week 24 up to week 52. Improvement in pain and reduction in concomitant glucocorticoid treatment were observed. Improvements in patient-reported outcomes were also seen in patients who did not reach remission or LDA. No new safety signals were detected.

CONCLUSIONS

A considerable proportion of patients with RA attained the target of remission or LDA after 12 weeks of ETN treatment. Even beyond that timepoint, the proportion of patients achieving treatment targets continued to increase up to week 52.

The beneficial effect of csDMARDs co-medication on drug persistence of first-line TNF inhibitor in rheumatoid arthritis patients: data from Czech ATTRA registry

The study aimed to compare treatment retention for first-line TNF inhibitor (TNFi) in the ATTRA registry patients receiving either combination with conventional synthetic DMARDs or TNFi as monotherapy. A retrospective multicenter study analyzed data of all adult patients with rheumatoid arthritis (n = 3032) starting TNF inhibitor as the first-line biological therapy in combination with csDMARDs or in monotherapy from January 1st 2012 to December 31st 2020. Kaplan-Meier method was employed to calculate drug retentions. Survival curves of treatment retentions were compared through Log-rank test between the studied subgroups. The hazard ratio for drug discontinuation was assessed through univariate cox regression models. In patients who started the first line TNFi therapy, the median treatment retention was 47.7 (42.2; 53.1) months for combination therapy and 22.7 (14.9; 30.6) months for TNFi monotherapy (p < 0.001). Estimated one-year survival was higher in patients on TNFi combined with csDMARDs as compared with TNFi monotherapy (75.3% vs 65.7%); two-year survival rate was 63.2% vs 49.2%, three-year survival rate was 55.4% vs 42.4% and five-year survival 44.9% vs 26.4% of patients. The estimated survival on the first TNFi was higher in patients taking combination therapy with methotrexate than with other csDMARDs (p = 0.003). Use of csDMARDs co-medication was associated with significantly better first TNFi drug survival compared to monotherapy. The combination of TNFi with MTX is more effective than the combination with leflunomide, which did not demonstrate a significant effect.

Could potentially calprotectin be a promising biomarker to oracle biologic therapy response in rheumatoid arthritis?

Background

The advent of novel biologic agents for the treatment of rheumatoid arthritis (RA) has proven to be highly productive. Nonetheless, high cost, side effects, and unresponsiveness to these agents dictates the assignment of biomarkers that can foretell treatment response. Currently, calprotectin (a member of the S100 protein family) is amongst the enormously studied candidates in this perspective. Yet, conflicting results have been published. The main purpose of this study was to explore the role of serum concentration of calprotectin to predict the response to biological therapy in RA patients, so as to customize RA treatment.

Results

Baseline serum calprotectin levels were significantly higher in RA patients compared to the control subjects (P value < 0.001). After receiving biologic therapy, a remarkable reduction (P < 0.001) in serum calprotectin was noted in RA cohort. Moreover, no correlation was found between the 28 joint count disease activity score (DAS28) and serum calprotectin levels neither before or after biologics. Intriguingly, no statistically significant association was detected between circulating calprotectin level and response to biological therapy.

Conclusion

Serum calprotectin concentrations could not be used as a biomarker to forecast clinical response to biological therapy in RA patients. However, further studies involving larger cohort of RA patients should be carried out to deliver more insight in this regard.

Budget Impact Analysis of the Introduction of Subcutaneous Infliximab (CT-P13 SC) for the Treatment of Rheumatoid Arthritis in the United Kingdom

BACKGROUND

CT-P13 subcutaneous (SC)-the first and only SC version of infliximab-is approved by the European Medicines Agency for the treatment of rheumatoid arthritis (RA). This new mode of infliximab administration will allow patients to self-inject at home, significantly reducing the number of outpatient visits and costs of intravenous (IV) administration. This paper describes the economic impact of introducing CT-P13 SC to the market from the UK societal perspective.

OBJECTIVE

The budget impact analysis was conducted to assess the financial impact of the adoption of CT-P13 SC over a 5-year period.

METHODS

A prevalence-based budget impact model was developed incorporating epidemiological data, administration cost data, and market share data. The analysis compared a "world with" CT-P13 SC scenario to a "world without" CT-P13 SC. A sensitivity analysis included dose escalation up to 4.1 mg/kg to reflect the real-world care delivery setting.

RESULTS

Compared to the "world without" scenario, the introduction of CT-P13 SC resulted in cost savings of ₤69.3 million in the UK over a 5-year period. In the scenario analysis, the saving increased to ₤173.5 million over 5 years.

CONCLUSION

Use of CT-P13 SC may lead to substantial cost savings for the UK society.

Cutaneous Autoimmune Phenomena of the Anti-TNFa Biosimilars. Casebased Review

BACKGROUND

Psoriasis (Pso) is a common chronic inflammatory disease affecting the skin, both sexes, and all ages. It can be associated with other chronic inflammatory musculoskeletal disorders and certain drugs, including tumor necrosis factor α (TNFα) antagonists.

CASE PRESENTATION

A 64-year-old man with seronegative rheumatoid arthritis (RA) refractory to leflunomide and prednisone was treated with SB-4 (Benepali), an etanercept biosimilar 50mg/week subcutaneously. He responded well to the treatment, but a year later, he developed erythematous skin eruptions affecting mainly in the palms of both hands. Skin biopsy showed a picture compatible with Pso. SB-4 was discontinued, and the skin lesions disappeared with the addition of topical steroid therapy. This is the only case of psoriatic skin lesions associated with SB-4 treatment.

CONCLUSION

Thus, we review and discuss the relevant literature of Pso cases related to SB-4 and other anti-TNFα biosimilars. Rheumatologists dealing with patients on anti-TNFα biosimilars should be aware of and recognize these complications.

Biologic Drugs for Rheumatoid Arthritis in the Context of Biosimilars, Genetics, Epigenetics and COVID-19 Treatment

Rheumatoid arthritis (RA) affects around 1.2% of the adult population. RA is one of the main reasons for work disability and premature retirement, thus substantially increasing social and economic burden. Biological disease-modifying antirheumatic drugs (bDMARDs) were shown to be an effective therapy especially in those rheumatoid arthritis (RA) patients, who did not adequately respond to conventional synthetic DMARD therapy. However, despite the proven efficacy, the high cost of the therapy resulted in limitation of the widespread use and unequal access to the care. The introduction of biosimilars, which are much cheaper relative to original drugs, may facilitate the achievement of the therapy by a much broader spectrum of patients. In this review we present the properties of original biologic agents based on cytokine-targeted (blockers of TNF, IL-6, IL-1, GM-CSF) and cell-targeted therapies (aimed to inhibit T cells and B cells properties) as well as biosimilars used in rheumatology. We also analyze the latest update of bDMARDs' possible influence on DNA methylation, miRNA expression and histone modification in RA patients, what might be the important factors toward precise and personalized RA treatment. In addition, during the COVID-19 outbreak, we discuss the usage of biologicals in context of effective and safe COVID-19 treatment. Therefore, early diagnosing along with therapeutic intervention based on personalized drugs targeting disease-specific genes is still needed to relieve symptoms and to improve the quality of life of RA patients.

Recent advances in the opioid mu receptor based pharmacotherapy for rheumatoid arthritis

INTRODUCTION

Opioids are used for severe forms of acute and cancer pain. Over the last years, their potential use in patients with noncancer pain such as those with rheumatoid arthritis (RA) has been postulated. A recent population-based comparative study showed that chronic opioid use was 12% vs. 4% among RA and non-RA patients, respectively. Another study showed an increase from 7.4% to 16.9% (2002 to 2015). In general, there has been an increasing tendency to use opioids in recent years.

AREAS COVERED

The authors have performed an extensive literature search using PubMed for articles including noncancer pain and the use of the mu opioid receptor (MOR) agonists in patients with RA.

EXPERT OPINION

Data is not sufficient to support opioid use for the treatment of chronic pain in patients with RA. Data is scarce and inconclusive. Rheumatologists should think and ponder the question: Why is this patient in pain? Differential diagnosis should include a disease flare, degenerative changes of the musculoskeletal system, and fibromyalgia. And while there are new strategies for opioid administration currently being researched, unfortunately, they are far from being applied to human subjects in the everyday clinical setting, and are still being evaluated at an experimental level.

[Survival of bDMARDs in bionaive patients with rheumatoid arthritis: data from a retrospective 12-month follow-up]

AIM

Analysis of survival on biological therapy in previously bionaive patients with rheumatoid arthritis (RA) during the first year of therapy in real clinical practice.

MATERIALS AND METHODS

The retrospective study included 204 adult patients with RA. In the hospital, patients were first prescribed therapy with various biological disease-modifying antirheumatic drugs (bDMARDs): infliximab, adalimumab, etanercept, certolizumab pegol, tocilizumab, abatacept (ABA), rituximab (RTM). Patients were divided by age in accordance with the classification adopted by WHO. Clinical forms of RA were presented: RA, seropositive for rheumatoid factor, RA, seronegative for rheumatoid factor, RA with extra-articular manifestations, adult-oneset Stills disease, juvenile RA. The reasons for the cancellation of bDMARD during the first year of treatment were: insufficient effectiveness (including primary inefficiency), adverse events, administrative reasons, clinical and laboratory remission, death.

RESULTS

A year after being included in the study, treatment was continued in 92 (45%) patients and was discontinued in 112 patients. The average time of treatment amounted to 0.750.33 years. The longest duration of treatment was in the RTM and ABA groups (0.920.22 and 0.830.29 years, respectively). In 56 (50%) patients, bDMARD was canceled due to insufficient effectiveness (including primary inefficiency), 28 patients (25%) due to the development of adverse reactions, 19 (17%) patients for administrative reasons, 7 (6.25%) patients due to drug remission. During the first year of therapy, there were 2 (1.75%) deaths due to severe comorbid conditions in patients, one of whom received RTM, the other tocilizumab.

CONCLUSION

Study showed that 45% of patients with RA continue treatment with first-time bDMARD for more than 12 months. The most common reason for discontinuation of therapy was its lack of effectiveness. The best survival rate of bDMARDs was observed in RTM and ABA. When selecting bDMARD in each case, it is necessary to take into account the continuity at all stages of treatment.

Systemic Sclerosis and Vaccinations: A Register-Based Cohort Study about Seasonal Influenza and Streptococcus pneumoniae Vaccination Rate and Uptake from Liguria Regional Center, Northwest Italy

Systemic sclerosis (SSc) is the connective tissue disease with the highest mortality and patients with chronic inflammatory immune-mediated diseases are at high risk of acquiring infections as they are often treated with immunosuppressive or biological drugs. This study, conducted among the patients followed by our clinical immunology, part of the Internal Medicine Department in the Ospedale Policlinico San Martino, Genoa, northwest Italy, has set itself the primary objective of analyzing the vaccine uptake and the vaccination coverage against both seasonal influenza and S. pneumoniae in a cohort of patients with SSc. We evaluated the influenza and pneumococcal vaccination rate among various subgroups of patients and the source of the recommendation for vaccination. We evaluated the vaccination rate changes between the two years considered in our study. We also calculated a binomial logistic regression between vaccination acceptance and clinical and demographics characteristics of the patients to evaluate the adjusted odds ratio (OR) of each factor on vaccination. The vaccination coverage that resulted was significantly higher than in other similar studies. Age over 65 years old, interstitial lung disease, and ongoing immunosuppressive therapy were significantly related with acceptance to both vaccinations using univariate analyses, but the multivariate logistic regression found a significant correlation only with the age and therapy factors.

Tumor Necrosis Factor (TNF) blocking agents are associated with lower risk for Alzheimer's disease in patients with rheumatoid arthritis and psoriasis

This large, retrospective case-control study of electronic health records from 56 million unique adult patients examined whether or not treatment with a Tumor Necrosis Factor (TNF) blocking agent is associated with lower risk for Alzheimer’s disease (AD) in patients with rheumatoid arthritis (RA), psoriasis, and other inflammatory diseases which are mediated in part by TNF and for which a TNF blocker is an approved treatment. The analysis compared the diagnosis of AD as an outcome measure in patients receiving at least one prescription for a TNF blocking agent (etanercept, adalimumab, and infliximab) or for methotrexate. Adjusted odds ratios (AORs) were estimated using the Cochran-Mantel-Haenszel (CMH) method and presented with 95% confidence intervals (CIs) and p-values. RA was associated with a higher risk for AD (Adjusted Odds Ratio (AOR) = 2.06, 95% Confidence Interval: (2.02–2.10), P-value <0.0001) as did psoriasis (AOR = 1.37 (1.31–1.42), P <0.0001), ankylosing spondylitis (AOR = 1.57 (1.39–1.77), P <0.0001), inflammatory bowel disease (AOR = 2.46 (2.33–2.59), P < 0.0001), ulcerative colitis (AOR = 1.82 (1.74–1.91), P <0.0001), and Crohn’s disease (AOR = 2.33 (2.22–2.43), P <0.0001). The risk for AD in patients with RA was lower among patients treated with etanercept (AOR = 0.34 (0.25–0.47), P <0.0001), adalimumab (AOR = 0.28 (0.19–0.39), P < 0.0001), or infliximab (AOR = 0.52 (0.39–0.69), P <0.0001). Methotrexate was also associated with a lower risk for AD (AOR = 0.64 (0.61–0.68), P <0.0001), while lower risk was found in patients with a prescription history for both a TNF blocker and methotrexate. Etanercept and adalimumab also were associated with lower risk for AD in patients with psoriasis: AOR = 0.47 (0.30–0.73 and 0.41 (0.20–0.76), respectively. There was no effect of gender or race, while younger patients showed greater benefit from a TNF blocker than did older patients. This study identifies a subset of patients in whom systemic inflammation contributes to risk for AD through a pathological mechanism involving TNF and who therefore may benefit from treatment with a TNF blocking agent.
