Toward Telemonitoring in Immune-Mediated Inflammatory Diseases: Protocol for a Mixed Attention Model Study

BACKGROUND

Rheumatic and musculoskeletal diseases (RMDs) are chronic diseases that may alternate between asymptomatic periods and flares. These conditions require complex treatments and close monitoring by rheumatologists to mitigate their effects and improve the patient's quality of life. Often, delays in outpatient consultations or the patient's difficulties in keeping appointments make such close follow-up challenging. For this reason, it is very important to have open communication between patients and health professionals. In this context, implementing telemonitoring in the field of rheumatology has great potential, as it can facilitate the close monitoring of patients with RMDs. The use of these tools helps patients self-manage certain aspects of their disease. This could result in fewer visits to emergency departments and consultations, as well as enable better therapeutic compliance and identification of issues that would otherwise go unnoticed.

OBJECTIVE

The main objective of this study is to evaluate the implementation of a hybrid care model called the mixed attention model (MAM) in clinical practice and determine whether its implementation improves clinical outcomes compared to conventional follow-up.

METHODS

This is a multicenter prospective observational study involving 360 patients with rheumatoid arthritis (RA) and spondylarthritis (SpA) from 5 Spanish hospitals. The patients will be followed up by the MAM protocol, which is a care model that incorporates a digital tool consisting of a mobile app that patients can use at home and professionals can review asynchronously to detect incidents and follow patients' clinical evolution between face-to-face visits. Another group of patients, whose follow-up will be conducted in accordance with a traditional face-to-face care model, will be assessed as the control group. Sociodemographic characteristics, treatments, laboratory parameters, assessment of tender and swollen joints, visual analog scale for pain, and electronic patient-reported outcome (ePRO) reports will be collected for all participants. In the MAM group, these items will be self-assessed via both the mobile app and during face-to-face visits with the rheumatologist, who will do the same for patients included in the traditional care model. The patients will be able to report any incidence related to their disease or treatment through the mobile app.

RESULTS

Participant recruitment began in March 2024 and will continue until December 2024. The follow-up period will be extended by 12 months for all patients. Data collection and analysis are scheduled for completion in December 2025.

CONCLUSIONS

This paper aims to provide a detailed description of the development and implementation of a digital solution, specifically an MAM. The goal is to achieve significant economic and psychosocial impact within our health care system by enhancing control over RMDs.

Breastfeeding Initiation, Duration, and Associated Factors in Mothers with Systemic Lupus Erythematosus

Objective: To study breastfeeding initiation, duration, and associated factors in patients with systemic lupus erythematosus (SLE), a cross-sectional study comparing with SLE and non-SLE mothers was conducted. Methods: Thirty patients with SLE who had pregnancy outcomes from September 2018 to December 2020 and 120 non-SLE patients (excluding mothers with other immune system diseases) were included in the study. Data on sociodemographic, obstetric, and SLE clinical information were collected. Breastfeeding initiation, breastfeeding duration, and reasons for not initiating breastfeeding were investigated via telephone. Results: The rate in breastfeeding of SLE group was significantly lower than non-SLE group (36.7% versus 86.7%, respectively, p < 0.001; odds ratio 0.059; 95% confidence interval 0.015-0.241). Non-SLE mothers had a longer duration of breastfeeding than mothers with SLE (log-rank p = 0.001). Fearing of the adverse effects of drugs on babies is the main reason (68.4%) for not initiating breastfeeding in SLE group. Infants with high weight and Apgar scores, primipara women, and having a college degree were significantly associated with breastfeeding among patients with SLE. Conclusion: SLE women showed a lower breastfeeding rate and shorter breastfeeding duration. Postpartum medications are safe for lactation in most patients with SLE. Targeted intervention programs that enhance breastfeeding consultations are required for this group.

The economic burden of biologic disease-modifying antirheumatic drugs in rheumatoid arthritis patients in the United States

BACKGROUND

Previous U.S. economic burden estimates for rheumatoid arthritis (RA) varied from $85.6 to 148.1 billion annually. However, these estimates do not reflect comparative amounts spent on RA treatment options in addition to other medical expenditures. Therefore, this study's goal was to comparatively analyze the overall economic burden of U.S. patients treated for RA using conventional disease-modifying antirheumatic drugs (DMARDs) versus TNF alpha biologic DMARDs.

RESEARCH DESIGN AND METHODS

This retrospective observational study analyzed Medical Expenditure Panel Survey Household Component data from 2016 to 2018. Healthcare utilization, total medical expenditures, and out-of-pocket expenditures were compared between RA medication groups.

RESULTS

Three hundred twenty-five adult RA patients experiencing 603 RA-related events, including at least one medical visit, between 2016 and 2018 were identified. Rheumatic arthritis-attributable medical expenditures among patients prescribed DMARDs were $11.4 billion. Average total medical expenditures were significantly higher for the TNF alpha biologic group $26,216.67 (95% CI: $19,502.84-$32,930.5) versus $5,388.52 (95% CI: $2,768.25-$8,008.79) for the conventional DMARD group (p<0.001).

CONCLUSIONS

RA patients receiving TNF alpha biologics experienced significantly higher total medical and out-of-pocket expenditures; however, they have experienced fewer or no occurrences of high-cost drivers of healthcare utilization compared to patients receiving conventional DMARDs.

Antirheumatic Drugs against COVID-19 from the Perspective of Rheumatologists

Coronavirus disease 2019 (COVID-19) remains a global threat to humanity. Its pathogenesis and different phases of disease progression are being elucidated under the pandemic. Active viral replication activates various immune cells and produces large amounts of inflammatory cytokines, which leads to the cytokine storm, a major cause of patient death. Therefore, viral inhibition is expected to be the most effective early in the course of the disease, while immunosuppressive treatment may be useful in the later stages to prevent disease progression. Based on the pathophysiology of rheumatic diseases, various immunomodulatory and immunosuppressive drugs are used for the diseases. Due to their mechanism of action, the antirheumatic drugs, including hydroxychloroquine, chloroquine, colchicine, calcineurin inhibitors (e.g., cyclosporine A and tacrolimus), glucocorticoids, cytokines inhibitors, such as anti-tumor necrosis factor-α (e.g., infliximab), anti-interleukin (IL)-6 (e.g., tocilizumab, sarilumab, and siltuximab), anti-IL-1 (e.g., anakinra and canakinumab) and Janus kinase inhibitors (e.g., baricitinib and tofacitinib), cytotoxic T lymphocyte-associated antigen 4 blockade agents (e.g., abatacept), and phosphodiesterase 4 inhibitors (e.g., apremilast), have been tried as a treatment for COVID-19. In this review, we discuss the mechanisms of action and clinical impact of these agents in the management of COVID-19.

Safety of the Methotrexate-leflunomide Combination in Rheumatoid Arthritis: Results of a Multicentric, Registry-based, Cohort Study (BiobadaBrasil)

OBJECTIVE

To evaluate the safety of the methotrexate (MTX)-leflunomide (LEF) combination in rheumatoid arthritis (RA), comparing it with other therapeutic schemes involving conventional synthetic (cs-) and biologic (b-) disease-modifying antirheumatic drugs (DMARDs) or Janus kinase inhibitors (JAKi).

METHODS

Patients with RA starting a treatment course with a csDMARD (without previous use of bDMARD or JAKi) or their first bDMARD/JAKi were followed up in a registry-based, multicentric cohort study in Brazil (BiobadaBrasil). The primary outcome was the incidence of serious adverse events (SAEs); secondary outcomes included serious infections. Multivariate Cox proportional hazards models and propensity score matching analysis (PSMA) were used for statistical comparisons.

RESULTS

In total, 1671 patients (5349 patient-years [PY]) were enrolled; 452 patients (1537 PY) received MTX + LEF. The overall incidence of SAEs was 5.6 per 100 PY. The hazard of SAEs for MTX + LEF was not higher than for MTX or LEF (adjusted HR [aHR] 1.00, 95% CI 0.76-1.31, P = 0.98). MTX + LEF presented a lower hazard of SAEs (aHR 0.56, 95% CI 0.36-0.88, P = 0.01) and infectious SAEs (aHR 0.48, 95% CI 0.25-0.94, P = 0.03) than bDMARDs/JAKi with MTX or LEF. MTX + LEF presented lower hazard of SAEs than MTX + sulfasalazine (SSZ; aHR 0.33, 95% CI 0.16-0.65, P = 0.002). Analysis using PSMA confirmed the results obtained with traditional multivariate Cox analysis.

CONCLUSION

In our study, MTX + LEF presented a relatively good overall safety profile in comparison to MTX + SSZ and schemes involving advanced therapies in RA.

Cardio-Rheumatology: Two Collaborating Disciplines to Deal with the Enhanced Cardiovascular Risk in Autoimmune Rheumatic Diseases

In Part 1 of this Thematic Issue entitled "Systemic Autoimmune Rheumatic Diseases and Cardiology", a panel of specialists and experts in cardiology, rheumatology, immunology and related fields discussed the cardiovascular complications of spondyloarthritides, rheumatoid arthritis, Sjogren's syndrome and vasculitides, as well as relevant cardiovascular issues related to non-biologic and biologic disease-modifying anti-rheumatic drugs (DMARDs), and provided their recommendations for prevention and management of these complications. In part 2 of this Thematic Issue, experts discuss the enhanced cardiovascular risk conferred by additional autoimmune rheumatic diseases (ARDs), including systemic lupus erythematosus, the antiphospholipid syndrome, psoriasis and psoriatic arthritis and juvenile idiopathic arthritis. These, and the previous articles, place inflammation as the key common link to explain the enhanced risk of cardiovascular complications in patients with ARDs. It follows that treatment should probably target inflammation. From all these contemporary reviews, the conclusion that is derived further supports the notion of the emerging field of Cardio- Rheumatology where physicians and experts from these two disciplines collaborate in risk stratification and optimization of preventive strategies and drug therapies in patients with ARDs.

Concerns, Healthcare Use, and Treatment Interruptions in Patients With Common Autoimmune Rheumatic Diseases During the COVID-19 Pandemic

OBJECTIVE

To assess concerns and healthcare-related behaviors of patients with autoimmune rheumatic diseases during the coronavirus disease 2019 (COVID-19) pandemic.

METHODS

Adults from the United States with rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), and systemic lupus erythematosus (SLE) from the ArthritisPower Patient-Powered Research Network and CreakyJoints patient community completed surveys. Concerns and behaviors were compared among patients with different autoimmune conditions, disease-modifying antirheumatic drug (DMARD) use, and geographic measures of urban status, income, education, and COVID-19 activity.

RESULTS

Among 1517 participants (925 RA, 299 PsA, 185 AS, 108 SLE), mean age was 55.1 years, 88.3% were female, and 89.5% were White. COVID-19 concerns were similar across the country and were higher in biologic users (P < 0.001). Avoidance of doctor's office visits (56.6%) or laboratory testing (42.3%) and use of telehealth (29.5%) were more common in urban areas. Among participants receiving a DMARD without COVID-19 or other respiratory illness, 14.9% stopped a DMARD, with 78.7% of DMARD interruptions not recommended by a physician. DMARD stopping was more common in participants with lower socioeconomic status (SES) and in participants who avoided an office visit (OR 1.46, 95% CI 1.04-2.04) or reported lack of telehealth availability OR 2.26 (95% CI 1.25-4.08).

CONCLUSION

In the early months of the COVID-19 pandemic, patients with RA, PsA, AS, and SLE frequently avoided office visits and laboratory testing. DMARD interruptions commonly occurred without the advice of a physician and were associated with SES, office visits, and telehealth availability, highlighting the need for adequate healthcare access and attention to vulnerable populations during the pandemic.

Assessment and Comparison of the Efficacy of Methotrexate, Prednisolone, Adalimumab, and Tocilizumab on Multipotency of Mesenchymal Stem Cells

Mesenchymal stem cell (MSC)-based articular regeneration might be beneficial for both protecting and rebuilding cartilaginous tissues in the management of rheumatoid arthritis. However, it is unclear how current immunosuppressive strategies influence the multipotency of MSCs. The present study was undertaken to profile the direct effectiveness of major antirheumatic drugs including methotrexate, prednisolone, adalimumab, and tocilizumab on the multipotency of MSCs, with a special focus on chondrogenesis. The inhibitory effects of methotrexate on adipogenesis, osteogenesis, and chondrogenesis were observed to occur in a dose-dependent manner in an in vitro differentiation system. Prednisolone enhanced adipogenesis, but reduced alkaline phosphatase activity in osteoprogenitors and suppressed the formation of chondrospheroids. Adalimumab suppressed alkaline phosphatase activity, while tocilizumab diminished osteogenesis and chondrogenesis of MSCs in vitro. Chondrogenesis of antirheumatic drug-treated MSCs was also evaluated in vivo using a scaffolded spheroid-engrafted murine model. The biologics examined appeared to be relatively safe for cartilaginous formation, but methotrexate and prednisolone exhibited opposing influences on chondrogenesis. Taken together, these results reveal the direct efficacy of major antirheumatic agents on the multipotency of MSCs. Therefore, our findings suggest that optimization of medication protocols is further required for therapeutic approaches involving cartilaginous tissue engineering.

Antirheumatic drugs for COVID-19 treatment based on the phases of the disease: Current concept

COVID-19 disease is the most recent pandemic, since it has affected more than four and a half million people and caused more than 300,000 deaths. It is a very complex systemic disease in terms of pathogenesis, treatment, and prognosis. Pharmacological treatment may include antiviral and antimalarial drugs, antibiotics, monoclonal antibodies, corticosteroids as well as low-molecular-weight heparins to prevent the evolution of the disease from reaching the severe inflammatory phase that can lead to respiratory complications, multiple organ failure, disseminated intravascular coagulation (DIC), and finally death. Therefore, pending the development of the much sought-after vaccine, there needs to be a multidisciplinary approach to tackling this disease, and it is essential to use different medical treatments at the correct pathogenic moment. The aim of this article is to evaluate the rationale and reason behind the use of antirheumatic drugs, by expert point of view, in the various phases of the disease. Another important aspect in the management of the disease is to identify patients at high risk, both to change their lifestyle and to correct the state of their health through non-pharmacological measures for improving their immuno-balance. Our literature review reveals the important role and the therapeutic potential of antirheumatic agents in preventing the progression of the disease and aiding recovery from the disease. However, there is a lack of clinical evidence to support the use of these agents, indicating that further randomized controlled studies are required.

Effects of overweight and underweight on the treatment outcomes of rheumatoid arthritis patients treated with biological drugs: A retrospective observational descriptive study

WHAT IS KNOWN AND OBJECTIVE

The effects of the body size condition (overweight and underweight) on the outcome of antirheumatic drugs are unclear. The aim of this study was to elucidate the relationship between body size and treatment outcomes in rheumatoid arthritis patients treated with biological antirheumatic drugs.

METHODS

A retrospective observational descriptive study was conducted at Tokyo Women's Medical University, Medical Center East, from June 2015 to May 2018. Primary and secondary outcomes were defined as antirheumatic treatment ineffectiveness and antirheumatic treatment discontinuation due to any side effects, respectively. Multivariate logistic regression analysis was used to determine the risk factors for the outcomes and to calculate the odds ratio (OR) and the 95% confidence interval (95% CI).

RESULTS AND DISCUSSION

A total of 297 patients were included. Primary and secondary outcomes were observed in 42 (14%) and 11 (4%) of the patients, respectively. Multivariate logistic regression analysis demonstrated that a body mass index (BMI) ≥25 kg/m² (OR = 4.22, 95% CI; 1.69-10.5, P = .002) was associated with rheumatoid arthritis treatment ineffectiveness and that BMI <18.5 kg/m² (OR = 5.87, 95% CI; 1.25-27.5, P = .025) and tacrolimus use (OR = 9.06, 95% CI; 1.37-60.1, P = .022) were associated with antirheumatic treatment discontinuation due to any side effects. The cut-off dose for tacrolimus was 0.5 mg/day.

WHAT IS NEW AND CONCLUSION

Overweight affects antirheumatic drug efficacy. Underweight and tacrolimus use increased the discontinuation of antirheumatic drugs due to side effects. A validation study is needed to confirm the reliability of these results.

The Association of Anti-Aminoacyl-Transfer Ribonucleic Acid Synthetase Antibodies in Patients With Rheumatoid Arthritis and Interstitial Lung Disease

Objectives

This study aims to analyze the distribution and clinicopathological characteristics of anti-aminoacyl-transfer ribonucleic acid (tRNA) synthetase (ARS) antibodies in rheumatoid arthritis patients.

Patients and methods

We retrospectively studied the anti-ARS antibody levels in 228 RA patients' (44 males, 184 females; mean age 62.9±14.0 years; range 23 to 88 years) sera from their medical charts. We determined the association with anti-cyclic citrullinated peptide antibody levels, interstitial lung disease (ILD), rheumatoid factor, and methotrexate or biological disease modifying antirheumatic drug treatments.

Results

Anti-ARS antibodies were detected in 14 RA patients (6.1%). ILD complications were significantly higher among anti-ARS antibody-positive patients (57.1% vs 22.4%, p<0.05). Levels of anti-threonyl-tRNA-synthetase (anti-PL-7) and anti-alanyl-tRNA-synthetase (anti-PL-12), two anti-ARS antibodies, were higher in RA patients with concurrent ILD (both p<0.05). Myositis and ILD worsening were not observed in three anti-ARS antibody- positive patients despite biological disease modifying antirheumatic drug administration. There was no difference in anti-cyclic citrullinated peptide and rheumatoid factor specificities between patients with or without ARS antibodies.

Conclusion

Anti-ARS antibodies were detected in RA patients, with higher prevalence in patients with concurrent ILD. RA patients, specifically those with ILD complications, should be tested for anti-ARS antibodies.

Tofacitinib Therapy for Rheumatoid Arthritis: A Direct Comparison Study between Biologic-naïve and Experienced Patients

Objective This study was designed to directly compare the outcomes of tofacitinib therapy for methotrexate-refractory rheumatoid arthritis (RA) between biologic-naïve patients and patients who had experienced an inadequate response to biological agents. Methods We prospectively enrolled and followed 113 patients who had a high or moderate clinical disease activity index (CDAI) (36 biologic-naïve patients and 77 biologic-experienced patients). Patients received 5 mg of tofacitinib twice daily. Effectiveness and adverse events were examined at month 6 of treatment. Results At month 6, 65 patients (57.5%) reached CDAI50, which is defined as achieving ≥50% improvement. The number of previous biological agents was twice as high in CDAI50 non-responders as in responders (2.2 versus 1.1, p<0.001), but there was no significant difference in the type of previous agents or the reason for discontinuation. According to a multivariate logistic regression analysis, the previous use of biological agents [odds ratio (OR) 4.48, p=0.002] and the concurrent use of prednisolone (OR 2.40, p=0.047) were associated with a failure to achieve a CDAI 50 response. Biologic-naïve patients were more likely to achieve CDAI50 than biologic-experienced patients (80.6% versus 46.8%, p=0.001). Mean CDAI values were higher in biologic-experienced patients (11.4 versus 4.8, p=0.001), and remission rates were higher in biologic-naïve patients (41.7% versus 11.7%, p=0.001). Biologic-naïve patients more rapidly achieved remission. Rates of discontinuation resulting from adverse events were similar in both groups. Conclusion Although tofacitinib can provide an effective treatment option for intractable RA patients, its impact on outcomes is lower in patients with previous biologic failure.
