Treatment with tumor necrosis factor inhibitors may slow disease progression in people with spondyloarthritis

2021-06-18
(Press-News.org) Murat Torgutalp and colleagues investigated the longitudinal association between radiographic sacroiliitis progression and treatment with TNFi in patients with early axSpA in a long-term inception cohort. The results were shared in an oral session at the 2021 EULAR congress.

Based on the availability of at least two sets of sacroiliac joint (SIJ radiographs), 166 people with non-radiographic axialspondyloarthritis (nr-axSpA), and135 with radiographic (r-axSpA), from the German Spondyloarthritis Inception Cohort (GESPIC) were included in the analysis. Two trained and calibrated central readers scored the radiographs, and if both scored an image as definite radiographic sacroiliitis, the patient was classified as having r-axSpA. The association between previous and current TNFiuse, and change in the sacroiliitis sum score over 2 years was analysed.

At baseline, 9 (3.0%) patients were treated with a TNFi, and 87 (28.9%) patients received at least one TNFiduring the entire follow-up period. While receiving 12or more months of TNFi in the previous interval was associated with lower progression of the sacroiliitis sum score compared to not receiving TNFi in the previous interval, this was not the case in patients who received TNFi for longer than12 months in the current 2-year interval. The significant association between TNFi use for longer than12 months in the previous interval and progression in the sacroiliitis sum score were confirmed in the adjusted analysis. In addition, a similar trend for the beneficial effects was observed in different models, which included other treatment definitions with TNFi in the previous 2-year interval.

The authors concluded that TNFi treatment was associated with slowing radiographic sacroiliitis progression in people with axSpA. This effect became evident 2-4 years after treatment initiation.

Decline in excess risk of dementia and heart failure in patients with rheumatoid arthritis

2021-06-18
RA is an inflammatory autoimmune disease that causes pain, swelling and stiffness in the joints. It can also cause fatigue, and the underlying inflammation may affect other body systems. Dementia is a symptom of damage to the brain, which can be caused by a number of different diseases - for example, Alzeimer's. Symptoms include memory loss, difficulty concentrating, confusion, and mood changes. It is not known what causes all types of dementia, but it is it thought that some of the damage could be caused by other underlying diseases. Heart failure happens when ...

Inflammation of the eye after drug withdrawal in children with arthritis

2021-06-18
Uveitis occurs in up to 20% of children with JIA, although this varies depending on the specific type of JIA that each child has. Jens Klotsche and colleagues shared new data at the 2021 EULAR congress analysing the risk of uveitis events after discontinuing disease-modifying antirheumatic drugs (DMARD) in children with one of two JIA categories: extended oligoarthritis and rheumatoid factor (RF)-negative polyarthritis. The data for the analysis came from two ongoing biologic registers: the German Biologics in Pediatric Rheumatology (BiKeR) registry, and the Juvenile arthritis Methotrexate/Biologics long-term Observation (JuMBO) study. Adverse events and reports about uveitis events during treatment and after discontinuation of DMARDs were collected. ...

Evolution -- two routes to the same destination

2021-06-18
Fruit flies have found at least two solutions to the problem of sorting their sex chromosomes: a matter of life and death. Sex determination in animals often depends on the unequal segregation of specific chromosomes. Female cells generally possess two X chromosomes, while male cells contain one X and one Y chromosome. The latter, which is inherited from the male parent, has far fewer genes than the X. In the fruit fly Drosophila, male cells make up for the fact that they have only one X chromosome by boosting the level of expression of all of its genes by a factor of 2. This phenomenon, which is known as dosage compensation, requires that the X chromosome in males be regulated differently from all the others. A team of molecular biologists at Ludwig-Maximilians-Universitaet (LMU) ...

Graphene drum: Researchers develop new phonon laser design

Graphene drum: Researchers develop new phonon laser design
2021-06-18
Professor Konstantin Arutyunov of the HSE Tikhonov Moscow Institute of Electronics and Mathematics (MIEM HSE), together with Chinese researchers, has developed a graphene-based mechanical resonator, in which coherent emission of sound energy quanta, or phonons, has been induced. Such devices, called phonon lasers, have wide potential for application in information processing, as well as classical and quantum sensing of materials. The study is published in the journal Optics Express. Using an analogy with photons, quanta of the electromagnetic spectrum, there are also particles of sound energy, phonons. In fact, these are artificially introduced objects in physics - quasi-particles, which correspond to vibrations ...

The Earth has a pulse -- a 27.5-million-year cycle of geological activity

The Earth has a pulse -- a 27.5-million-year cycle of geological activity
2021-06-18
Geologic activity on Earth appears to follow a 27.5-million-year cycle, giving the planet a "pulse," according to a new study published in the journal Geoscience Frontiers. "Many geologists believe that geological events are random over time. But our study provides statistical evidence for a common cycle, suggesting that these geologic events are correlated and not random," said Michael Rampino, a geologist and professor in New York University's Department of Biology, as well as the study's lead author. Over the past five decades, researchers have proposed cycles ...

VIMS study uncovers new cause for intensification of oyster disease

VIMS study uncovers new cause for intensification of oyster disease
2021-06-18
A new paper in Scientific Reports led by researchers at William & Mary's Virginia Institute of Marine Science challenges increased salinity and seawater temperatures as the established explanation for a decades-long increase in the prevalence and deadliness of a major oyster disease in the coastal waters of the mid-Atlantic. Dr. Ryan Carnegie, the paper's lead author, says "We present an entirely new lens through which we can view our last 35 years of oyster history in the Chesapeake Bay region. We now know the great intensification of Dermo disease in the 1980s wasn't simply due to drought. It was more fundamentally due to the emergence of a new and highly virulent form of Perkinsus marinus, the parasite that causes Dermo." In an unusual twist, the team's evidence ...

There is an unacceptable delay to diagnosis in axial spondyloarthritis

2021-06-18
The Axial Spondyloarthritis International Federation (ASIF) set out to coordinate a comprehensive evidence-based global review of the factors influencing the current diagnosis delay in axSpA, and to produce a definitive report that shines a light on these barriers, as well as providing a resource that can ultimately empower a range of international stakeholders to reduce this delay. At the 2021 EULAR congress, Wendy Gerhart and colleagues report the results of a full literature review and two virtual global forum events, involving patients and patient group ...

An increase in giant cell arteritis cases associated with peaks in COVID-19 prevalence

2021-06-18
Ben Mulhearn and colleagues estimated the incidence of GCA seen during the COVID-19 pandemic and compared it to data from 2019, before the pandemic hit. The two distinct peaks of COVID-19 reflected by UK hospital admissions of COVID-19-positive patients allowed the authors to investigate the relationship in time between COVID-19 and GCA incidence. At the Royal National Hospital for Rheumatic Diseases in Bath, UK, there were 61 probable or definite GCA diagnoses made in 2020 compared to 28 in 2019- representing an excess of 33 cases in 2020, or an increase of 118%.Taking into account the fact that41% of the ...

This population-based cohort study including all individuals registered in the Information System for Research in Primary Care (SIDIAP)- which covers over80% of the population of Catalonia, Spain. This information was linked to region-wide SARS-CoV-2 testing, hospital and mortality records. Outpatient diagnoses of COVID-19, hospitalizations and deaths with COVID-19 were identified between 1st March and 6th May 2020. A total of 5,586,565 ...

Two U of M Medical School studies provide new evidence to battle drug price increases

2021-06-18
MINNEAPOLIS/ST. PAUL (06/18/2021) -- Two recent studies led by researchers from the University of Minnesota Medical School add new evidence to the impact of how drug price increases affect U.S. patients and the overall cost of health care. The first study, published today in the JAMA Network Open, provides new data on how dramatic increases in anti-infective drug prices altered the overall cost of outpatient health care and decreased patient access to appropriate drug treatment. The study protocol was reviewed by the U.S. Centers for Disease Control and Prevention and scanned ...
