L'incidence des infections opportunistes chez les patients atteints de rhumatisme psoriasique traités avec des agents biologiques et des agents synthétiques ciblés : Une revue systématique et une méta-analyse

Front Pharmacol 2022;13:992713 doi: 10.3389/fphar.2022.992713

This is the largest meta-analysis to date, assessing the risk of OIs (Opportunistic infection) in patients with PsA. In coming to this conclusion, a systematic review and meta-analysis was undertaken to estimate the incidence of OIs following treatment with b- and tsDMARDs.

Infections chez les patients atteints de polyarthrite rhumatoïde recevant du tofacitinib versus des inhibiteurs du facteur de nécrose tumorale : résultats de l'essai de Surveillance ORAL ouvert, randomisé et contrôlé

doi: 10.1136/ard-2022-222405

Post hoc analysis, using the final dataset from ORAL Surveillance, reveals a higher risk of non-serious infections and herpes zoster with tofacitinib vs TNFi, and higher risk of serious infection events with tofacitinib 10 mg BID versus TNFi, particularly in patients aged ≥65 years.

Zona incident et récurrent chez les patients séropositifs atteints de polyarthrite rhumatoïde et traités par bDMARD ou tsDMARD en première intention : une étude de cohorte à l'échelle nationale

Arthritis Res Ther. 2022;24(1):180

Herpes zoster (HZ) risk is significantly increased in seropositive RA patients with a history of HZ after the initiation of bDMARDs or tsDMARD. It is now well known that the incidence and recurrence of HZ are quite common in patients with RA in real-world clinical settings, yet there is limited evidence regarding bDMARD-dependent HZ risk among patients with a history of HZ prior to bDMARD use.

Le risque d'infection est-il plus élevé pendant le traitement par sécukinumab que par inhibiteurs du TNF ? Une étude observationnelle dans les pays nordiques

Rheumatology (Oxford). 2022 doi: 10.1093/rheumatology/keac358

Glintborg B et al, highlight in their recent research from the Nordic countries, that there is a low frequency of hospitalised infections during treatment with secukinumab or TNFi in patients with SpA and PsA. In clinical practice, secukinumab was found to double absolute risk of 1st year hospitalised infection compared with adalimumab, with the other TNFi treatments falling in between.

Identification of novel off targets of baricitinib and tofacitinib by machine learning with a focus on thrombosis and viral infection

Sci Rep. 2022 doi: 10.1038/s41598-022-11879-1

Established machine learning approaches, based on ligand similarity, identified previously unknown off-target interactions of baricitinib and tofacitinib, and adds to the evidence that these JAK inhibitors are promiscuous binders, and highlight the potential for repurposing.

Évaluation de la réponse à la vaccination anti-pneumococcique conjuguée 13-valent chez les patients atteints de polyarthrite rhumatoïde recevant de l'upadacitinib : résultats d'une étude d'extension ouverte de phase 2

RMD Open. 2022;8(1):e002110 doi: 10.1136/rmdopen-2021-002110

Vaccine sub-study of the BALANCE-EXTEND upadacitinib trial finds that approximately two-thirds of patients receiving upadacitinib 15 mg once-daily achieve a satisfactory humoral response to pneumococcal 13-valent conjugate (PCV-13) vaccine, despite receiving concomitant methotrexate (MTX).It is well known that a weakened immune response, comorbidities and immunosuppressant drug therapy all contribute to an increased susceptibility to infections in patients with RA. Likewise, the morbidity and mo...

Prise en charge clinique du zona chez les patients atteints de polyarthrite rhumatoïde ou de rhumatisme psoriasique traités par tofacitinib

Rheumatol Ther. 2021. Epub ahead of print. doi: 10.1007/s40744-021-00390-0

This post hoc analysis provides the first detailed description of the management and outcomes of HZ events in tofacitinib RA and PsA clinical studies.While prior studies have characterised the increased HZ risk with JAKinibs, the clinical management of these events has not been detailed.To this end, Winthrop, et al. analysed data from 21 RA and 3 PsA clinical studies to evaluate how HZ events and their sequelae were clinically managed during the RA and PsA tofacitinib clinical development progra...

Incidence and risk factors for herpes zoster in patients with rheumatoid arthritis receiving upadacitinib: a pooled analysis of six phase III clinical trials

Ann Rheum Dis. 2021. Epub ahead of print. doi: 10.1136/annrheumdis-2021-220822.

JAKinibs have been linked with an increased risk of HZ in patients with RA. To this end, Winthrop, et al. evaluated data from six Phase III clinical trials to determine the incidence of HZ in the upadacitinib (UPA)-treated patients with RA and identify potential risk factors for the development of HZ in these patients.Analysis of data provides further support for the need for continued vigilance and monitoring for signs of herpes zoster (HZ) in patients receiving UPA, particularly in Asian popul...

Reactivation of hepatitis B virus infection in patients with rheumatoid arthritis receiving tofacitinib

Int J Rheum Dis. 2021. Epub ahead of print

Tofacitinib could induce Hepatitis B virus (HBV) reactivation in RA patients.With previous studies having already demonstrated that RA patients using biologic agents, might experience HBV reactivation leading to acute hepatitis, hyperbilirubinemia, and death, Wang, et al. aimed to investigate HBV reactivation in patients with RA receiving tofacitinib. They found that Hepatitis B surface antigen positive patients receiving tofacitinib have a high incidence rate of HBV reactivation, which could be...

Risk of herpes zoster (shingles) in patients with rheumatoid arthritis under biologic, targeted synthetic and conventional synthetic DMARD treatment: data from the German RABBIT register

Ann Rheum Dis. 2021 Jul 28:annrheumdis-2021-220651

A 3.6-fold increased risk of herpes zoster (HZ) is associated with tsDMARDs, and an increased risk is associated with bDMARDs, compared with csDMARDs. It is now well known that patients with RA have an increased risk of developing herpes zoster (HZ), and that incidence rates appear to be increased with TNF and JAK inhibitors. To this end, Redeker, et al. used data from the German RABBIT Registry to compare event and incidence rates of HZ in patients with RA treated with the three different DMAR...
