Safety of Biologic and Nonbiologic Disease-modifying Antirheumatic Drug Therapy in Veterans with Rheumatoid Arthritis and Hepatitis C Virus Infection

Drug treatment algorithm and recommendations from the 2020 update of the Japan College of Rheumatology clinical practice guidelines for the management of rheumatoid arthritis-secondary publication

OBJECTIVE

The aim of this study was to update the Japan College of Rheumatology (JCR) clinical practice guidelines (CPG) for the management of rheumatoid arthritis (RA; JCR CPG for RA) according to recent changes in the medical environment in Japan. This article is a digest version of the guidance.

METHODS

We used the Grading of Recommendations, Assessment, Development, and Evaluation method to update the 2014 JCR CPG for RA. A consensus was formed by CPG panel members.

RESULTS

We identified 36 important clinical questions regarding drug treatment and developed corresponding recommendations for RA. The recommendations included the following RA medications: non-steroidal anti-inflammatory drugs, corticosteroids, conventional synthetic disease-modifying antirheumatic drugs, biological disease-modifying antirheumatic drugs, anti-receptor activator for nuclear factor-κB ligand antibodies, and Janus kinase inhibitors, as well as the tapering and discontinuation of these medications. Recommendations regarding the efficacy and safety of treatments in the elderly and patients with comorbidities were also developed. Finally, we used these recommendations to create an original algorithm for drug treatment for RA based on the Treat-to-Target approach.

CONCLUSION

The 2020 JCR CPG for RA provides a useful tool for rheumatologists, health care professionals, and patients with RA, enabling shared decision-making in a variety of clinical situations.

Systematic literature review informing the 2022 EULAR recommendations for screening and prophylaxis of chronic and opportunistic infections in adults with autoimmune inflammatory rheumatic diseases

OBJECTIVE

To conduct a systematic literature review (SLR) on the screening and prophylaxis of opportunistic and chronic infections in autoimmune inflammatory rheumatic diseases (AIIRD).

METHODS

SLR (inception-12/2021) based on the following search domains: (1) infectious agents, (2) AIIRD, (3) immunosuppressives/immunomodulators used in rheumatology, (4) screening terms and (5) prophylaxis terms. Articles were retrieved having the terms from (1) AND (2) AND (3) plus terms from (4) OR(5). Databases searched: PubMed, Embase and Cochrane Library.

EXCLUSION CRITERIA

studies on postoperative infections, paediatric AIIRD, COVID-19, vaccinations and non-Εnglish literature. Study quality was assessed with Newcastle-Ottawa scale for non-randomised controlled trials (RCTs), RoB-Cochrane for RCTs, AMSTAR2 for SLRs.

RESULTS

From 5641 studies were retrieved, 568 full-text articles were assessed for eligibility, with 194 articles finally included. For tuberculosis, tuberculin skin test (TST) is affected by treatment with glucocorticoids and conventional synthetic disease modifying anti-rheumatic drugs (DMARDs) and its performance is inferior to interferon gamma release assay (IGRA). Agreement between TST and IGRA is moderate to low. For hepatitis B virus (HBV): risk of reactivation is increased in patients positive for hepatitis B surface antigen. Anti-HBcore positive patients are at low risk for reactivation but should be monitored periodically with liver function tests and/or HBV-viral load. Risk for Hepatitis C reactivation is existing but low in patients treated with biological DMARDs. For Pneumocystis jirovecii, prophylaxis treatment should be considered in patients treated with prednisolone ≥15-30 mg/day for >2-4 weeks.

CONCLUSIONS

Different screening and prophylaxis approaches are described in the literature, partly determined by individual patient and disease characteristics.

Direct antiviral drugs in the treatment of hepatitis C-infected rheumatoid arthritis Egyptian cohort: safety and clinical impact

BACKGROUND AND AIM

Data about the safety and efficacy of direct-acting antivirals (DAAs) in the treatment of hepatitis C virus (HCV) patients with concomitant rheumatoid arthritis (RA) are scarce. We assessed the impact and safety of DAAs treatment of hepatitis C on rheumatoid arthritis disease activity.

PATIENTS AND METHODS

Prospectively, we enrolled 65 patients with RA and HCV. A clinico-laboratory evaluation was done at baseline, including liver assessment and RA disease activity score-28 (DAS28). At 12 weeks of post-DAAs treatment, sustained virologic response (SVR12) and DAS28 were reevaluated.

RESULTS

The SVR12 was achieved in 59 (90.8%) patients. RA control was achieved in 47 (79.9%) patients. The post SVR12 DAS28 score was significantly lower than the baseline (3.32 ± 0.93 vs. 4.37 ± 0.90; P < 0.001). There was a significant decline in the mean values of serum anticyclic citrullinated peptide, rheumatoid factor, erythrocyte sedimentation rate and C-reactive protein after achieving an SVR12 (30.47 ± 12.37 vs. 57.61 ± 15.91 U/ml; 29.78 ± 19.58 vs. 55.14 ± 16.89 IU/ml; 17.13 ± 10.84 vs. 29.68 ± 14.32 mm/h and 5.76 ± 1.57 vs. 11.44 ± 4.13 mg/l, respectively; P < 0.05). RA activity and antirheumatic drugs were stepped-down [12 (20.3%) and 35 (59.3%) patients showed good and moderate RA response, respectively]. The baseline viral load, absence of cirrhosis and SVR12 were the only predictors of disease control (P  < 0.05). No drug-related adverse events or drug-related discontinuation.

CONCLUSIONS

Unlike interferon, HCV elimination by DAAs significantly improves RA activity and treatment outcome with high safety and efficacy.

Infectious complications of rheumatoid arthritis and psoriatic arthritis during targeted and biological therapies: a viewpoint in 2020

Biological therapies have improved the outcomes of several major inflammatory, autoimmune and also neoplastic disorders. Those directed towards cytokines or other soluble mediators, cell-surface molecules or receptors or various components of intracellular signalling pathways may be associated with the occurrence of infections whose diversity depends on the particular immune target. In this context and following a keynote lecture given by one of us at the European League Against Rheumatism meeting on June 2018, a multidisciplinary group of experts deeply involved in the use of targeted and biological therapies in rheumatoid and psoriatic arthritis decided to summarise their recent vision of the immunological basis and epidemiology of infections occurring during targeted and biological therapies, and provide useful indications for their management and prevention.

Infection risk in patients undergoing treatment for inflammatory arthritis: non-biologics versus biologics

Introduction: Despite the therapeutic effectiveness of biologics targeting immune cells or cytokines in patients with inflammatory arthritis, which reflects their pathogenic roles, an increased infection risk is observed in those undergoing biological treatment. However, there are limited data regarding the comparison of infection risks in inflammatory arthritis patients treated with non-biologics (csDMARDs), biologics (bDMARDs), including tumor necrosis factor (TNF) inhibitors and non-TNF inhibitors, or targeted synthetic (ts)DMARDs.Areas covered: Through a review of English-language literature as of 30 June 2019, we focus on the existing evidence on the risk of infections caused by bacteria, Mycobacterium tuberculosis, and hepatitis virus in inflammatory arthritis patients undergoing treatment with csDMARDs, bDMARDs, or tsDMARDs.Expert opinion: While the risks of bacterial and mycobacterial infection are increased in arthritis patients treated with csDMARDs, the risks are further higher in those receiving bDMARDs therapy, particularly TNF inhibitors. Regarding HBV infection, antiviral therapy may effectively prevent HBV reactivation in patients receiving bDMARDs, especially rituximab. However, more data are needed to establish effective preventive strategies for HBsAg-negative/HBcAb-positive patients. It seems safe to use cyclosporine and TNF inhibitors in patients with HCV infection, while those undergoing rituximab therapies should be frequently monitored for HCV activity.Abbreviations: ABT: abatacept; ADA: adalimumab; AS: ankylosing spondylitis; bDMARDs: biologic disease-modifying anti-rheumatic drugs; CKD: chronic kidney disease; COPD: chronic obstructive pulmonary disease; CS: corticosteroids; CsA: cyclosporine A; csDMARDs: conventional synthetic disease-modifying anti-rheumatic drugs; CZP: certolizumab; DAAs: direct-acting antiviral agents; DM: diabetes mellitus; DOT: directly observed therapy; EIN: Emerging Infections Network; ETN: etanercept; GOL: golimumab; GPRD: General Practice Research Database; HBV: hepatitis B virus; HBVr: HBV reactivation; HBsAg+: HBsAg-positive; HBsAg-/anti-HBc+: HBsAg-negative anti-HBc antibodies-positive; HCV: hepatitis C virus; HCQ: hydroxychloroquine: IFX: infliximab; IL-6: interleukin-6; JAK: Janus kinase; LEF: leflunomide; LTBI: latent tuberculosis infection; mAb: monoclonal antibody; MTX: methotrexate; OR: odds ratio; PsA: psoriatic arthritis; PMS: post-marketing surveillance; RA: rheumatoid arthritis; TNF: tumor necrosis factor; TNFi: tumor necrosis factor inhibitor; SCK: secukinumab; SSZ: sulfasalazine; TOZ: tocilizumab; RCT: randomized controlled trial; RR: relative risk; RTX: rituximab; 3HP: 3-month once-weekly isoniazid plus rifapentine; TB: tuberculosis; tsDMARDs: targeted synthetic disease-modifying anti-rheumatic drugs; UTK: ustekinumab; WHO: World Health Organization.

Effectiveness and safety of chronic hepatitis C treatment with direct-acting antivirals in patients with rheumatic diseases: A case-series

Objectives: To assess the effectiveness and safety of interferon-free direct-acting antiviral (DAA) therapy for patients with concomitant hepatitis C virus (HCV) infection and rheumatic diseases (RDs), including rheumatoid arthritis (RA).Methods: This was a single-center observational case-series study conducted in Japan from 2014 to 2018. The primary endpoint was the sustained virological response (SVR) rate 24 weeks after the end of therapy (EoT24). We also evaluated hepatological and rheumatological outcomes and adverse events.Results: Of the 2314 patients with RDs, 18 received DAA therapy (RA = 11, other RDs = 7). The SVR rate for the initial DAA therapy was 89% (16/18). The remaining two achieved SVR with secondary DAA therapy. Along with HCV elimination, hepatological parameters improved significantly from baseline to EoT24. During the study period, no patients newly developed cirrhosis or HCC after HCV elimination. Several patients showed improvement in RDs activity. In RA patients, the simplified disease activity index decreased significantly from baseline to EoT24 (median [interquartile range]: 11.53 [5.14-14.89] vs. 4.06 [2.08-9.05], respectively). On-treatment adverse events were minimal, while two patients experienced tuberculosis reactivation after EoT.Conclusion: DAA therapy was effective and safe, providing hepatological and rheumatological benefits in HCV-infected patients with RDs. Immune reconstitution following HCV elimination should be noted.

Italian consensus recommendations for the management of hepatitis C infection in patients with rheumatoid arthritis

Objectives: The recent introduction of direct-acting antiviral agents (DAAs) which can eliminate Hepatitis C virus (HCV) had revolutionized the treatment of HCV infections also in a complex clinical setting such as the patients with rheumatoid arthritis (RA). HCV elimination is also opportune due to the availability of more efficient immunosuppressive drugs, whose effect on the course of HCV infection is largely unknown.Methods: Consensus process was endorsed by the Italian Society of Rheumatology (SIR) and the Italian Society of Infectious and Tropical Diseases (SIMIT) to review the available evidence and produce practical, hospital-wide recommendations. The consensus panel consisted of 18 infectious diseases consultants, 20 rheumatologists and one clinical epidemiologist, who used the criteria of the Oxford Centre for Evidence-based Medicine to assess the quality of the evidence and the strength of their recommendations.Results: A core-set of statements about management of patients with RA and infection by HCV have been developed to help clinicians in their clinical practice.Conclusions: A screening for HCV should be performed in all RA patients and it is mandatory before starting an immunosuppressive therapy. Finally, a DAA treatment should be considered in all HCV-infected patients.Significance and InnovationsHCV antibodies should be investigated at the time of diagnosis of RA and, in any case, before starting immunosuppressive therapy with disease-modifying antirheumatic drugs (DMARDs).HCV eradication with DAA should be attempted as soon as possible, depending on patient conditions allowing a continuous oral treatment lasting 8-12 weeksConventional and biological DMARDs are allowed in patients with HCV infection, but they should be used cautiously in presence of advanced liver disease.
