Three-month tapering and discontinuation of long- term, low-dose glucocorticoids in senior patients with rheumatoid arthritis is feasible and safe: placebo-controlled double blind tapering after the GLORIA trial

Current practice, trends and attitudes of rheumatologists towards glucocorticoids use for rheumatoid arthritis (GURANTEE): a national cross-sectional survey across China

INTRODUCTION

To investigate current practices, changes, and perceptions of rheumatologists regarding GC use in RA patients.

METHODS

A cross-sectional survey was conducted using a structured questionnaire between April and August 2023. Rheumatologists from 31 province-level regions of Mainland China were invited to participate. Chi-squared tests were adopted to investigate the differences by sociodemographic characteristics.

RESULTS

1,717 rheumatologists from 598 hospitals completed the survey with a response rate of 92%. Up to 60% of participants expressed currently infrequent initiation of GC co-therapy with csDMARDs (hardly ever 7.0%; occasionally 24.6%; sometimes 29.1%), accompanied by a decline of frequency over time reported in 64.2%. Regarding attitudes towards bridging therapy with GC, 604 (35.2%) participants supported this approach, 468 (27.3%) opposed it, and 645 (37.6%) remained inconclusive. Time to GC discontinuation in context of csDMARDs was commonly reported within 6 months in current practice which has been narrowed over time. Reasons for chronic GC use were mostly reported due to suboptimal disease control, followed by the need of RA complications, and pre-existing comorbidities. After failure of GC cessation, majority of respondents (84.4%) would escalate RA therapy (commonly by addition of JAK inhibitors, TNF inhibitors), which usually or often facilitated the GC cessation. The most frequently reported advantages and weaknesses of GC were rapid and strong efficacy, adverse events, respectively. Regarding long-term low-dose GC use for RA, the percentage of respondents who supported, opposed, or depended on the situation were 15.9%, 17.2%, and 66.9%, respectively.

CONCLUSIONS

The current data demonstrate that GC initiation for RA treatment is not as frequent as before and the awareness of GC discontinuation is growing in current practice. Attitudes towards GC co-therapy with csDMARDs vary considerably and long-term low-dose GC use remain situation dependent.

Low-Dose Glucocorticoids in Older Patients with Rheumatoid Arthritis: What Does the Evidence Say?

The short-term use of glucocorticoids (GCs) in combination with methotrexate was recommended for the initial treatment of rheumatoid arthritis by the European League Against Rheumatism. A randomized controlled trial (GLORIA) showed that treatment of older patients with low-dose GCs in combination with disease-modifying anti-rheumatic drugs was more efficacious than disease-modifying anti-rheumatic drugs plus placebo in terms of disease activity control and prevention of joint destruction. Glucocorticoid-related adverse events were likely to increase relative to placebo, with no increase in serious adverse events and fractures over 2 years. Observational studies showed an increased risk of serious infections, cardiovascular events, and fractures associated with long-term continuation of GCs in older patients, but the adverse events may be associated not only with GC toxicity but also with poor disease control of rheumatoid arthritis. In the GLORIA study, low-dose GCs during 2 years could be tapered off safely, but many patients had a flare of disease activity after discontinuation of GCs. In the two representative large Japanese registries (IORRA and NinJa), the proportion of patients using GCs and non-tumor necrosis factor inhibitors increased with increasing age at disease onset, with a decreasing trend in methotrexate use. The proportion of patients in remission with GC treatment also increased with increasing age at onset. These suggested that it is not easy to discontinue GCs in older patients. If GCs cannot be terminated in the short term, it may be acceptable to use GCs to control disease activity for up to 2 years.

Autoantibody-negative rheumatoid arthritis: still a challenge for the rheumatologist

Increased research over the past 30 years has greatly improved the understanding of the pathophysiological mechanisms and clinical aspects of autoantibody-positive rheumatoid arthritis, resulting in improved management and outcomes. In contrast, the subset of rheumatoid arthritis that does not have autoantibodies (such as rheumatoid factor and anti-citrullinated protein autoantibodies) remains less well defined in its pathogenic mechanisms. Autoantibody-negative rheumatoid arthritis continues to pose diagnostic challenges, might respond differently to therapies, and appears to be burdened with different comorbidities and outcomes. The clear separation of rheumatoid arthritis according to serotypes is still a subject of uncertainty and controversy, and studies specifically focused on comparing rheumatoid arthritis and rheumatoid arthritis-like arthritides that do not have autoantibodies remain scarce. The purpose of this Review is to summarise the peculiarities that make autoantibody-negative rheumatoid arthritis different from its autoantibody-positive counterpart, with the aim of generating debate and stimulating further research on this challenging condition.

Viewpoint: Glucocorticoids in the treatment of rheumatoid arthritis: points to (re)consider

Glucocorticoids (prednisone) are essential in the treatment of RA and other autoimmune diseases. They are widely used, but treatment guidelines advise against. This viewpoint article explains why and suggests a way forward.
