Anti-Citrullinated Protein Antibody Titers Are Independently Modulated by Both Disease Activity and Conventional or Biologic Anti-Rheumatic Drugs.

ABSTRACT: This study aimed to analyze the factors that influence anti-citrullinated protein antibody (ACPA) titers in a seropositive early arthritis (EA) population under non-protocolized treatment with disease-modifying anti-rheumatic drugs (DMARDs). A total of 130 ACPA-positive patients from the PEARL (Princesa Early Arthritis Longitudinal) study were studied along a 5-year follow-up. Sociodemographic, clinical, and therapeutic variables, along with serum samples, were collected at five visits by protocol. Anti-cyclic citrullinated peptide 2 (CCP2) ACPA titers were measured by ELISA. The effect of different variables on anti-CCP2 titers was estimated using longitudinal multivariate analysis models, nested by visit and patient. Data from 471 visits in 130 patients were analyzed. A significant decrease in anti-CCP2 titers was observed at all time-points, compared to baseline, following the decline of disease activity. In the multivariate analysis, active or ever smoking was significantly associated with the highest anti-CCP2 titers while reduction in disease activity was associated with titer decline. After adjusting for these variables, both conventional synthetic (cs) and biologic (b) DMARDs accounted for the decline in anti-CCP2 titers as independent factors. Conclusion: In patients with EA, an early and sustained reduction in ACPA titers can be detected associated with the decline in disease activity, irrespective of the treatment used.

Conventional and biologic disease-modifying anti-rheumatic drugs for osteoarthritis: a meta-analysis of randomized controlled trials.

Project description:ObjectivesThe role of inflammation in OA is controversial and it is unclear whether suppressing inflammation with conventional or biologic DMARDs is effective. A systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted to compare DMARDs with placebo in participants with symptomatic OA.MethodsDatabases (Medline, Embase, Allied and Complementary Medicine Database, Web of Science and Cochrane Library), conference abstracts and ClinicalTrials.gov were searched to end of November 2017 for placebo-controlled RCTs of DMARDs, including biologics, in symptomatic OA. Pain data at treatment peak time point were extracted and combined using a random-effects meta-analysis. Markers of inflammation and adverse events were extracted and reviewed. Risk of bias assessment was conducted using Cochrane's tool.ResultsEleven RCTs (1205 participants) were meta-analysed, including six for conventional DMARDs (757 participants) and five for biologics (448 participants). Overall, DMARDs were statistically superior to placebo [effect size (ES) = 0.18, 95% CI: 0.03, 0.34], although the difference was not clinically significant (0.5 ES threshold). Furthermore, no statistically significant differences were observed in sub-analysis of high-quality trials (ES = 0.11, 95% CI : -0.06, 0.28), biologics (ES = 0.16, 95% CI: -0.02, 0.34) or conventional DMARDs (ES = 0.24, 95% CI: -0.05, 0.54). No difference was found between erosive vs non-erosive hand OA, hand vs knee OA or anti-IL1 vs anti-TNF biologics.ConclusionDMARDs did not offer clinically significant pain relief above placebo in OA. This poor efficacy indicates that inflammation may not be a prime driver for OA pain.

Response to Biologic Disease-Modifying Anti-Rheumatic Drugs after Discontinuation of Anti-Tumor Necrosis Factor Alpha Agents for Rheumatoid Arthritis.

Project description:The aim of this study was to compare the response between subsequent use of anti-tumor necrosis factor ? (anti-TNF) agents and biologic disease-modifying anti-rheumatic drugs (bDMARD) with other mechanism of action (MOA) in rheumatoid arthritis (RA) patients with history of anti-TNF treatment as their first bDMARD.A retrospective chart review was conducted at eight community-based rheumatology practices in the United States in 2012. Routine Assessment of Patient Index Data 3 (RAPID3) response was measured by comparing baseline and 6-month scores. Poor response was defined as decrease <1.8 points, follow-up score >12, or treatment discontinuation before 6 months. Percentages of patients with good and good or moderate RAPID3 response were compared for second and third biologics. Multivariate models controlled for potential confounders.Of 176 patients whose charts were abstracted, 122 (69.3%) received another anti-TNF agent after they discontinued their first anti-TNF. RAPID3 scores were available for 160 patients. A patient receiving a second bDMARD with another MOA had a higher good or moderate response than a patient receiving anti-TNF (53.5 vs. 30.7%, p = 0.01). In the multivariate models, treatment with another MOA was more likely to produce a good RAPID3 response [odds ratio (OR), 2.42; 95% confidence interval (CI), 1.05-5.58] or a good or moderate response (OR, 2.21; 95% CI, 1.23-3.97) than treatment with an anti-TNF.In patients who have discontinued anti-TNF agents as their first bDMARD, RAPID3 response rates are better for those receiving agents with a different MOA rather than another anti-TNF. Physicians should consider using a bDMARD with a different MOA as the next bDMARD for RA patients whose anti-TNF agent has failed.

Trajectories of Adherence to Biologic Disease-Modifying Anti-Rheumatic Drugs in Tuscan Administrative Databases: The Pathfinder Study.

Project description:Scanty information on clustering longitudinal real-world data is available in the medical literature about the adherence implementation phase in rheumatoid arthritis (RA). To identify and characterize trajectories by analyzing the implementation phase of adherence to biologic Disease-Modifying Anti-Rheumatic Drugs (DMARDs), we conducted a retrospective cohort drug-utilization study using Tuscan administrative databases. RA patients were identified by a validated algorithm, including the first biologic DMARD supply from 2010 to 2015, RA specialist visit in the year before or after the first supply date and RA diagnosis in the five years before or in the year after the first supply date. We observed users for three years or until death, neoplasia, or pregnancy. We evaluated adherence quarterly through the Medication Possession Ratio. Firstly, we identified adherence trajectories and described the baseline characteristics; then, we focused on the trajectory most populated to distinguish the related sub-trajectories. We identified 952 first ever-biologic DMARD users in RA (712 females, mean age 52.7 years old, standard deviation 18.8). The biologic DMARD mostly supplied was etanercept (387 users) followed by adalimumab (233). Among 935 users with at least 3 adherence values, we identified 49 fully-adherent users, 829 continuous users, and 57 early-discontinuing users. Significant differences were observed among the index drugs. After focusing on the continuous users, three sub-trajectories were identified: continuous-steady users (556), continuous-alternate users (207), and continuous-declining users (66). No relevant differences emerged at the baseline. The majority of first ever-biologic DMARD users showed a continuous adherence behavior in RA. The role of adherence potential predictors and the association with effectiveness and safety outcomes should be explored by further studies.

Decreased chronic kidney disease in rheumatoid arthritis in the era of biologic disease-modifying anti-rheumatic drugs

Project description:ABSTRACT Background We investigated the incidence of chronic kidney disease (CKD) progression and its factors relevant to patients with stable rheumatoid arthritis (RA). Methods We enrolled consecutive patients with RA who had initiated treatment with a biologic disease-modifying anti-rheumatic drug (bDMARD) at our institution and continued the same drug for >5 years between 2001 and 2016. Patients with CKD at bDMARD initiation were excluded. C-reactive protein (CRP) level, Clinical Disease Activity Index (CDAI) score and estimated glomerular filtration rate were measured every 6 months. Results We included 423 patients, with 196 on tumour necrosis factor inhibitors, 190 on tocilizumab and 37 on abatacept. Among these patients, 34 (8.0%) progressed to CKD within 5 years. The mean CRP level and CDAI score over 5 years were significantly lower in patients without CKD progression than in those with CKD progression (P < .001 and P = .008, respectively). Multivariable analysis revealed that age at bDMARD initiation [odds ratio (OR) 1.05, P = .002], non-steroidal anti-inflammatory drug use (OR 3.47, P = .004) and mean CRP >0.14 mg/dL (OR 5.89, P = .015) were independently associated with CKD progression, while tocilizumab use was associated with a decreased risk of CKD progression (OR 0.31, P = .027). Conclusions Controlling inflammation contributes to the inhibition of CKD progression in RA patients.

An update on the use of conventional and biological disease-modifying anti-rheumatic drugs in hand osteoarthritis.

Project description:Osteoarthritis (OA) is a highly prevalent condition worldwide associated with pain, progressive disability, reduced participation in social activities, and impaired quality of life. Despite its growing burden, the therapeutic options are still limited and almost exclusively addressed to symptoms' management, while no disease-modifying OA drugs able to prevent or retard disease progression are actually available. For these reasons, in the last decades, relevant efforts to find new potential therapeutic targets in OA have been made and a number of existing conventional and biological disease-modifying anti-rheumatic drugs (DMARDs), including hydroxychloroquine (HCQ), methotrexate (MTX), tumor necrosis factor (TNF)-α, interleukin (IL)-1, and IL-6 inhibitors, commonly used to treat inflammatory rheumatic diseases, have been repurposed for the treatment of OA and explored also in hand osteoarthritis (HOA). The current narrative review was aimed to provide a comprehensive and updated understanding of the possibilities and the criticisms related to the treatment of HOA with conventional and biological DMARDs. Unfortunately, therapy with conventional and biologic drugs in HOA has not achieved the expected success, despite a rationale for their use exists. Thus, our findings outline the urgent need to enhance the exploration of HOA basic molecular mechanisms to find new potential therapeutic targets, personalized for each patient, and appropriate for the different subsets of HOA and for the different phases of disease.

Incidence of COVID-19 in a cohort of adult and paediatric patients with rheumatic diseases treated with targeted biologic and synthetic disease-modifying anti-rheumatic drugs.

Project description:ObjectivesTo investigate the incidence of COVID-19 in a cohort of adult and paediatric patients with rheumatic diseases receiving targeted biologic and synthetic disease modifying anti-rheumatic drugs (tDMARDs) and to explore the possible effect of these treatments in the clinical expression of COVID-19.MethodsA cross-sectional study comprising of a telephone survey and electronic health records review was performed including all adult and paediatric patients with rheumatic diseases treated with tDMARDs in a large rheumatology tertiary centre in Barcelona, Spain. Demographics, disease activity, COVID-19 related symptoms and contact history data were obtained from the start of the 2020 pandemic. Cumulative incidence of confirmed cases (SARS-CoV-2 positive PCR test) was compared to the population estimates for the same city districts from a governmental COVID-19 health database. Suspected cases were defined following WHO criteria and compared to those without compatible symptoms.Results959 patients with rheumatic diseases treated with tDMARDs were included. We identified 11 confirmed SARS-CoV-2 positive cases in the adult cohort and no confirmed positive cases in the paediatric cohort. COVID-19 incidence rates of the rheumatic patient cohort were very similar to that of the general population [(0.48% (95% CI 0.09 to 0.87%)] and [0.58% (95% CI 0.56 to 0.60%)], respectively. We found significant differences in tDMARDs proportions between the suspected and non-suspected cases (p=0.002).ConclusionAdult and paediatric patients with rheumatic diseases on tDMARDs do not seem to present a higher risk of COVID-19 or a more severe disease outcome when compared to general population.

Use of Anti-Tumor Necrosis Factor Therapy: A Retrospective Study of Monotherapy and Adherence to Combination Therapy with Non-Biologic Disease-Modifying Anti-Rheumatic Drugs.

Project description:IntroductionThis study examined the use of anti-tumor necrosis factor (anti-TNF) monotherapy, adherence with non-biologic disease-modifying anti-rheumatic drugs (nbDMARDs) in patients receiving a combination of anti-TNF therapies and nbDMARDs, and the impact of nbDMARD adherence on anti-TNF persistence among patients with rheumatoid arthritis (RA).MethodsPatients with RA (aged ≥18 years) from a US commercial health plan with claims for anti-TNFs (2006-2010) were defined as either biologic-naive or -exposed anti-TNF initiators based on previous nbDMARD use. Adherence to nbDMARDs and anti-TNF persistence were estimated. Cox regression estimated the association between nbDMARD adherence and anti-TNF persistence.ResultsAmong 9764 patients identified (mean age 50.2 years; 78% female), 55% of biologic-naive patients and 49% of previously exposed patients initiated any combination therapy during follow-up. Among biologic-naive combination therapy patients, 53% adhered to nbDMARD therapy <80% of the time while receiving anti-TNF therapies; 33% had <60% adherence. Compared with the most adherent patients, patients adherent to nbDMARDs 20% to 79% of the time were 30% to 20% more likely to discontinue their anti-TNF therapy in the period >90 days after starting the anti-TNF therapy. This relationship was not observed for patients with nbDMARD adherence of <20% (who were less likely to discontinue their anti-TNF therapy during the first 90 days of treatment).ConclusionAlmost one-third of patients with RA receiving anti-TNF therapy received it as pure monotherapy. About one-third of combination therapy recipients had <60% adherence to nbDMARDs. Higher nbDMARD adherence may be associated with better anti-TNF persistence after an initial treatment period.

COVID-19 and Disease-Modifying Anti-rheumatic Drugs.

Project description:Purpose of reviewPatients on disease-modifying anti-rheumatic drugs (DMARDs) remain concerned about potential risks of severe COVID-19 outcomes. Meanwhile, several DMARDs have been proposed as COVID-19 therapies.Recent findingsIn patients with autoimmune diseases, baseline glucocorticoid use is associated with severe COVID-19. While classes of DMARDs (e.g., conventional synthetic, targeted synthetic, and biologic) do not appear to be associated with higher risk, specific medications such as rituximab and sulfasalazine may be associated. Randomized clinical trials (RCTs) show that glucocorticoids reduce mortality in severe COVID-19. RCTs suggest other agents, such as baricitinib, may improve COVID-19 outcomes in certain populations. Baseline glucocorticoid use raises the risk of severe COVID-19 in patients with autoimmune diseases, but glucocorticoids are an effective treatment for those with severe COVID-19. Further research is needed to inform DMARD management in autoimmune disease patients during the pandemic and the role of DMARDs in COVID-19 treatment.

Association between biologic disease modifying anti-rheumatic drugs and incident hypertension in patients with rheumatoid arthritis: Results from prospective nationwide KOBIO Registry.

Project description:There has been some debate between biologic disease modifying anti-rheumatic drugs (bDMARDs) treatment and hypertension (HTN) in rheumatoid arthritis (RA). The aim of this study was to determine the effect of bDMARDs on the development of HTN in patients with RA.A total of 996 patients eligible for analysis were recruited from the Korean College of Rheumatology Biologics & Targeted Therapy (KOBIO) registry from 2012 to 2018. The bDMARDs were tumor necrosis factor (TNF) inhibitors, abatacept, and tocilizumab. The cDMARDs included methotrexate, hydroxychloroquine, and leflunomide. The incidence rate and 95% confidence interval of HTN were estimated using the Kaplan-Meier method. Hazard ratio (HR) of risk factors associated with hypertension was assessed by cox proportional hazard model analysis.Among the 996 patients, 62 patients (6.2%) were newly diagnosed with HTN. There were differences in incidence rate of HTN among conventional DMARDs (cDMARDs), TNF inhibitors, tocilizumab, and abatacept during the follow-up period (P = .015). Kaplan-Meier analysis showed that there was a significant difference in incident HTN only between cDMARDs and tocilizumab (P = .001). Systolic blood pressure and positive rheumatoid factor were associated with development of HTN (HR = 1.049, P = .016 and HR = 1.386, P = .010, respectively). Cox proportional hazard model analysis showed no difference in the development of HTN between bDMARDs and cDMARDs in RA.This study showed that bDMARDs treatment might not increase risk of incident HTN in patients with RA, compared to cDMARDs.
