Unincreased risk of hospitalized infection under targeted therapies versus methotrexate in elderly patients with rheumatoid arthritis: a retrospective cohort study

Arthritis Res Ther. 2022 doi: 10.1186/s13075-022-02807-9

Retrospective, longitudinal, population-based study shows that despite an overall higher incidence of hospitalised infection (HI) in both elderly and older elderly patients compared to young patients, the risks of HI in patients exposed to targeted therapy versus MTX is not significantly increased.

Effectiveness of TNF-inhibitors, abatacept, IL6-inhibitors and JAK-inhibitors in 31 846 patients with rheumatoid arthritis in 19 registers from the ‘JAK-pot’ collaboration

Ann Rheum Dis. 2022 doi: 10.1136/annrheumdis-2022-222586

Observational study of data, from large international collective of registers, finds similar overall drug retention rates between RA treatment groups.

Comparison of drug retention of TNF inhibitors, other biologics and JAK inhibitors in RA patients who discontinued JAK inhibitor therapy

Rheumatology (Oxford) 2022 doi: 10.1093/rheumatology/keac285

Real-world population-based study shows that a switch to a second JAKinib results in a higher drug retention, as compared to switching to a TNFi, in patients with RA who discontinue original JAKinib therapy.

Two Phase 3 Trials of Baricitinib for Alopecia Areata

N Engl J Med. 2022. Epub ahead of print doi: 10.1056/NEJMoa2110343

Phase 3 trials in patients with severe alopecia areata show that baricitinib is superior to placebo with respect to hair regrowth at 36 weeks.
Alopecia areata is characterised by nonscarring hair loss that can affect any hair-bearing site. Although mild cases of this emotionally- and psychosocially-distressing autoimmune disease may resolve within 12 months, more severe forms of the disease are unlikely to remit without treatment.

A Retrospective Study of the Efficacy of JAK Inhibitors or Abatacept on Rheumatoid Arthritis-Interstitial Lung Disease

Inflammopharmacology. 2022. Epub ahead of print doi: 10.1007/s10787-022-00936-w

This study of the effectiveness of JAKinibs or abatacept in patients with RA-interstitial lung disease (RA-ILD) shows that treatment is related to stability or improvement of RA-ILD in over 80% of patients.

Oral surveillance and JAK inhibitor safety: the theory of relativity

Nat Rev Rheumatol. 2022. Epub ahead of print doi: 10.1038/s41584-022-00767-7

Putting the data into context, Winthrop, et al. conclude that the ORAL Surveillance data are not dissimilar to those from the original developmental programme, which suggested additional safety concerns at the 10 mg dosage and that resulted in the 5 mg twice daily dosage as the approved dose for RA.Following the recent results of the ORAL Surveillance (ORALSURV) study, and the consequent changes to the utilisation of JAKinibs, made by the regulatory authorities, Winthrop, et al. aim to put the O...

Effectiveness of baricitinib and tofacitinib compared with bDMARDs in RA: results from a cohort study using nationwide Swedish register data

Rheumatology (Oxford). 2022. Epub ahead of print doi: 10.1093/rheumatology/keac068

Data from the Swedish Rheumatology Quality Register and Swedish Registries, show a higher treatment retention and overall equivalent or better treatment response on baricitinib, compared with bDMARDs or tofacitinib, but no statistically significant differences between tofacitinib and bDMARDs.In this largest population-based study to date, comparing RA patients initiating baricitinib, tofacitinib or bDMARDs, Barbulescu, et al. help to fill some of the current knowledge gaps surrounding the effica...

Effect of JAK inhibitors on high- and low-density lipoprotein in patients with rheumatoid arthritis: a systematic review and network meta-analysis

Clin Rheumatol. 2022. Epub ahead of print doi: 10.1007/s10067-021-06003-z

Systematic review and network meta-analysis highlight that RA patients who receive recommended doses of the five approved JAK inhibitors (tofacitinib, baricitinib, upadacitinib, filgotinib, and peficitinib) are likely to experience an increase in serum low- and high-density lipoprotein (LDL and HDL) levels.JAK inhibitors have been associated with alterations in levels of LDL and HDL cholesterol, which may lead to dyslipidaemia (an important risk factor for cardiovascular disease). However, the e...

Clinical Management of Herpes Zoster in Patients With Rheumatoid Arthritis or Psoriatic Arthritis Receiving Tofacitinib Treatment

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...
