Rheumatoid arthritis (RA) is an autoimmune disorder, which primarily affects the joints and is characterized by inflammation and pain. RA most commonly affects the hands and wrists, but can also affect other parts of the body. There is currently no cure for RA, but treatment options have improved considerably in recent years with the development of new therapies and treatment strategies.
Conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) are well established as a standard treatment for RA, used to slow down progression of the disease through broad restriction of the immune systems. Biologic DMARDs (bDMARDs) take a more targeted approach, but it is unclear if it is equally effective across the spectrum of types of RA. In particular, the serological status of people diagnosed with RA may be linked to long-term outcomes. Also, based on differences in associations with genetic and environmental risk factors, seropositive and seronegative disease are presumed to have different underlying pathophysiological mechanisms. However, whether serological status may also affect treatment responses to biological disease-modifying anti-rheumatic drugs (bDMARDs) is not completely clear.
In a recently completed study, Dr. Kaoru Takase-Minegishi and colleagues undertook a meta-analysis based on a systematic literature review including data from 28 randomized controlled trials (RCTs). The research team’s goal was to investigate whether the efficacy of bDMARDs differs in seropositive RA patients (seropositive) compared to those classified as seronegative. Some of the study participants were also receiving csDMARDs, while other were treated bDMARDs exclusively.
The research findings indicate that seropositivity was not associated with a better response to bDMARDs, regardless of whether patients were also receiving csDMARDs. Other outcomes mostly showed no significant difference between the groups, and efficacy was generally comparable between seropositive and seronegative patients for a range of treatment protocols.
Using the Vivli platform enabled the research team to include previously unpublished data, the first opportunity to perform meta-analysis on this complete dataset. Previously unpublished data are included in the Supplementary Material, available online alongside the article recently published in the journal Rheumatology. This research provides a very important additional perspective to the data reported from observational studies thus far, uncovering essential differences.

Rheumatoid arthritis (RA) poses a significant challenge due to its chronic nature and impact on joint health. While treatments have evolved, achieving remission remains elusive for many patients. Using a dataset from the Vivli repository, Dr. Ricardo Ferreira and a team of researchers delved into examining the assessment criteria for remission in RA, shedding light on the limitations of current approaches and proposing a new model—the dual target strategy.
The current standard of treatment is the Treat-to-Target (T2T) approach, which aims for remission or low disease activity. Dr. Ferreira’s team questioned the reliance on a single criterion, the patient global assessment (PGA/PtGA), included in composite measures for determining remission. Their study, drawing from extensive clinical trial data, notably revealed that 19% of patients failed to attain remission based solely on this patient-reported assessment, leading the team to explore a more comprehensive model. In a recent conversation with Vivli, Dr. Ferreira highlighted the research’s key finding: the lack of significant difference in radiographic outcomes between patients classified as “PGA-near-remission” versus those in full remission. This challenges the established understanding of remission incorporating the patient global assessment.
The research team has proposed a dual target strategy, which integrates patient-reported outcomes with objective measures like inflammation status and joint counts to assess inflammatory status and guide immunosuppressive therapy management. The second target (disease impact) would be assessed by informative patient-reported outcome measures, other than PGA. By assigning equal significance to subjective experiences and clinical data, this innovative approach proposes a new benchmark for remission in RA management. Moreover, it has the potential to guide both pharmaceutical and nonpharmacological interventions.
It is anticipated that the dual target strategy has a more patient-centric approach; integrating subjective experiences with objective clinical markers holds promise for improving treatment efficacy and enhancing patient outcomes. With key RA researchers expressing interest in this model, the dual target strategy could significantly change both RA management, and the experience of patients navigating this complex condition. A pragmatic, multicenter, randomized controlled trial is currently being prepared to test this strategy.

In a recent study led by Dr. Sarah Nevitt, a senior research associate at the University of Liverpool, a team of researchers examined the effectiveness of various antiepileptic drugs (AEDs) used as monotherapy for people experiencing seizures due to epilepsy. Epilepsy, a common neurological disorder, results from abnormal electrical discharges in the brain, causing recurrent seizures. Typically, around 60% to 70% of individuals with epilepsy achieve longer-term remission, often shortly after beginning treatment with antiepileptic drugs.
Dr. Nevitt and her team sought to compare the performance of 12 different AEDs in terms of treatment failure, remission, and occurrence of first seizures among both children and adults with focal onset or generalized tonic‐clonic seizures. They analyzed data from an extensive collection of clinical trials encompassing more than 22,000 participants, incorporating individual patient data from various studies using a network meta-analysis.
The analysis revealed some key insights. Older drugs like phenobarbitone and phenytoin demonstrated better seizure control for both focal and generalized seizures but had poorer long-term retention rates compared to newer medications such as lamotrigine and levetiracetam. Sodium valproate emerged as the top choice for achieving control and remission of generalized tonic‐clonic seizures, although it might not be suitable for everyone, especially people of childbearing age, due to associated risks.
These findings, published in the Cochrane Library, have already influenced the update of UK guidelines in 2022, providing immediate impact on the treatment of individuals newly diagnosed with epilepsy in the UK. In a recent conversation with Vivli, Dr. Nevitt highlighted that these results are guiding the approach to epilepsy treatment, emphasizing the importance of considering both efficacy and potential side effects when selecting appropriate medications for individuals experiencing seizures.
