(Press-News.org) The estimated prevalence of psoriatic arthritis (PsA) in people with psoriasis ranges widely –between 6% and 42% – but in most cases, skin symptoms precede PsA, thus making skin psoriasis a model for pre-PsA.2 Assuming that there are shared pathways in the pathogenesis, it is possible that stringent treatment of moderate-to-severe psoriasis could reduce progression to clinically overt PsA.3,4 Biologic treatments are effective at controlling psoriasis, but there are no conclusive data that these treatments help prevent people from developing PsA. Several risk factors for transition have previously been identified by a EULAR taskforce.5 Identifying a profile of those psoriasis patients likely to go on to develop joint involvement is key to the idea of intercepting PsA.3
This retrospective study used Big Data from a global network of electronic records – making it possible to look at over 1 million people with psoriasis to compare the incidence of new-onset PsA between those receiving a first- or second-line biologic for psoriasis. This included tumour necrosis factor inhibitors (TNFi) and biologics directed against interleukins (IL-12i, -23i, -17i, and -12/23i). The incidence of PsA was compared in the different cohorts at 5 years, and throughout the follow up, using the first-line TNFi population as a comparator.
The results showed that the risk of developing PsA during first-line treatment was 37% lower with an IL-12/23i, and 39% lower with IL-23i compared to TNFi at 5 years. For those on second-line treatment, the risk was 32% lower with IL-12/23i and 31% lower with IL-23i at 3 years than with a first-line TNFi. In both first- and second-line treatment, IL-23i presented a 47% lower probability of developing PsA compared to IL-17i at 3 and 5 years.
These kinds of analyses based on ‘Big Data’ offer an opportunity to obtain information on the efficiency of drugs in real life. This large study is relevant because it explores the incidence of PsA in matched, adjusted cohorts with a 5-year follow-up. According to these data, IL-12/23i and IL-23i reduce the incidence of PsA compared to TNFi and IL-17i, both in naïve and bio-experienced patients. As more knowledge becomes available, the concept of intercepting PsA before it becomes clinically apparent becomes a possibility.

Predicting response in treatment-naïve RA
2024-06-12
The synovial tissue inflammation seen in RA shows high degree of heterogeneity – which may be a factor in people’s variable response to treatments. We also know that distinct synovial tissue macrophage subsets regulate inflammation and remission in rheumatoid arthritis.1 The potential of high-throughput analyses has been shown, and these technologies can help dissect disease heterogeneity and identify novel biomarkers that could be used in prognosis.2
To explore this further, 373 treatment-naïve RA patients were enrolled and given an ultrasound-guided synovial tissue biopsy. The synovitis degree and synovial pathotype was then determined for ...
Testing the systemic score for Still’s disease
2024-06-12
A multi-centre, observational, prospective study was designed to evaluate the clinical usefulness of the systemic score in predicting life-threatening evolution – defined as the development of macrophage activation syndrome (MAS) and/or mortality. The intention was also to derive a more aggressive clinical patient subset. To achieve this, Ruscitti and colleagues collected data from 597 patients taking part in the GIRRCS (Gruppo Italiano Di Ricerca in Reumatologia Clinica e Sperimentale) AOSD-study ...
Early RA: Disease trajectories and pain
2024-06-12
The 2024 EULAR congress in Vienna included a clinical abstract session focusing on pain and prognosis in RA, where two groups presented their research into ways to characterise early RA.
The first looked at dissecting early RA patient trajectories through time-independent disease state patterns of inflammation in blood or joints. Presenting the work, Nils Steinz said “Previous studies have identified smooth time trajectories of rapid, slow, or no progression of disease activity, assessed through DAS28. In real life, we observe more chaotic disease evolvements – and particularly the detours could ...
Testing the thresholds
2024-06-12
However, this recommendation is not always followed in practice. This could be because the ASDAS was developed for research, and it is not known how well it performs in daily practice. Possibly, the cut-off of 2.1 as currently endorsed may be too strict in an everyday setting. To address this, Webers and colleagues set out to investigate which ASDAS cut-off values correspond best with treatment intensification in practice.
Data were taken from a prospective multi-centre registry for SpA, and treatment ...
Ingestible microbiome sampling pill technology advances
2024-06-12
Significant progress has been made at Tufts University School of Engineering in the development of a small device, about the size of a vitamin pill, that can be swallowed and passed through the gastrointestinal tract to sample the full inventory of microorganisms in an individual’s gastro-intestinal tract. This device has the potential to advance research on the relationship between resident bacteria and a wide range of health conditions. It could also serve as a diagnostic tool for adjusting the microbiome or administering drugs to treat those conditions.
The device has completed ...
Just thinking about a location activates mental maps in the brain
2024-06-12
As you travel your usual route to work or the grocery store, your brain engages cognitive maps stored in your hippocampus and entorhinal cortex. These maps store information about paths you have taken and locations you have been to before, so you can navigate whenever you go there.
New research from MIT has found that such mental maps also are created and activated when you merely think about sequences of experiences, in the absence of any physical movement or sensory input. In an animal study, the researchers found that the entorhinal cortex harbors a cognitive map of what animals experience while they use a joystick to browse through a sequence of images. ...
Obesity-cancer connection discovery suggests strategies for improving immunotherapy
2024-06-12
Immune system cells called macrophages play an unexpected role in the complicated connection between obesity and cancer, a Vanderbilt University Medical Center-led research team has discovered.
Obesity increases the frequency of macrophages in tumors and induces their expression of the immune checkpoint protein PD-1 — a target of cancer immunotherapies. The findings, published June 12 in the journal Nature, provide a mechanistic explanation for how obesity can contribute to both increased cancer ...
Smartwatches offer window into Parkinson's disease progression
2024-06-12
Ubiquitous wearable technologies, like smartwatches, could help researchers better understand progressive neurological disorders like Parkinson’s disease and speed up the approval of new therapies, a critical need given that no drugs exist to slow progression of the world’s fastest growing brain disease.
New research appearing today in the journal njp Parkinson’s Disease adds to growing evidence that widely used and user-friendly consumer devices, in this instance an Apple Watch paired with an iPhone, ...
What the geologic record reveals about how oceans were oxygenated 2.3 billion years ago
2024-06-12
About 2.5 billion years ago, free oxygen, or O2, first started to accumulate to meaningful levels in Earth’s atmosphere, setting the stage for the rise of complex life on our evolving planet.
Scientists refers to this phenomenon as the Great Oxidation Event, or GOE for short. But the initial accumulation of O2 on Earth was not nearly as straightforward as that moniker suggests, according to new research led by a University of Utah geochemist.
This “event” lasted at least 200 million years. And tracking the accumulation of O2 in the oceans has been very difficult until now, ...
Incidence of dementia before age 65 years among World Trade Center attack responders
2024-06-12
About The Study: In this cohort study of World Trade Center responders who survived these unique exposures and participated in a longitudinal follow-up study of cognition from 2014 through 2022, when compared with responders with the lowest exposure levels or responders who used personalized protective equipment (PPE), more severe exposure to dust or debris was significantly associated with a higher risk of dementia before 65 years of age. This study suggests that the reliable use of PPE might help prevent the onset of dementia before age 65 years among individuals exposed to an uncontrolled building collapse. Future ...
