The heterogeneous nature of juvenile idiopathic arthritis (JIA), the use of biologics in childhood rheumatic diseases, and a look at the long-term outcomes for children with JIA are just some of the highlights from the pediatric rheumatology sessions at this year’s EULAR Congress in Madrid, June 14-17.

EULAR Standing Committee Chairperson for Paediatric Rheumatology Tadej Avcin, MD, PhD, said that a bench-to-bedside session on the heterogeneity of JIA on the afternoon of Thursday, June 15, would explore the biologic basis of the disease, the role of cytokine profiling, and the clinical variability in the disease.

“The classification of children with JIA is an ongoing process. ... For example, we know that children with early-onset antinuclear antibody–positive oligoarthritis are different from children with late-onset ANA-negative arthritis,” Dr. Avcin said in an interview.

“By highlighting the heterogeneity of JIA, we hope this session will contribute to the further understanding of differences between JIA subtypes, as well as contribute some scientific background for the further classification of children with JIA,” he said.

Another “not to miss” session from the pediatric program that will be held on the afternoon of Friday, June 16, is the open issues session on the use of biologic agents in JIA, according to Dr. Avcin, professor of pediatrics and head of the department of allergology, rheumatology, and clinical immunology at University Children’s Hospital, University Medical Center, Ljubljana, Slovenia.

Speaking on the long-term side effects of biologics, Joost Swart, MD, from Utrecht in the Netherlands will present some novel data from the large ongoing pharmacovigilance project Pharmachild that follows children aged 3-10 years who have been treated with methotrexate or a biologic.

At the same session, Pierre Quartier, MD, from Paris will take delegates through data on autoimmune phenomena that can occur in children who are on biologic treatment.

“We know that, in treating children with biologics, they can sometimes develop antidrug antibodies and various induced autoimmune phenomena. We would like to highlight this aspect so that physicians can have more of an overview of possible immune-mediated adverse effects in their patients,” Dr. Avcin said.

The session will also address what Dr. Avcin describes as an emerging and important clinical question: When and how do you discontinue treatment in children with sustained remission?

It’s a question he hopes Gerd Horneff, MD, from Germany will be able to shed some light on when he shares data on how frequently children experience disease flares after discontinuing treatment.

Another pediatric highlight is a morning session on Saturday, June 17, that will address the long-term outcomes of children with JIA.

A presentation by Marion van Rossum, MD, PhD, from the Netherlands will explore whether there are certain clinical or laboratory markers that can help identify children who are more likely to respond well to treatment, compared with other children.

Dirk Foell, MD, from Germany will follow with a session on immunological markers of remission in JIA.

As Dr. Avcin explained, immunological markers such as S100 proteins have shown promise as a biomarker of subclinical active disease.

“Even if a child appears to have clinically inactive disease, elevated levels of these markers may help predict which children will remain in remission after discontinuing treatment and which children may be at an increased risk of a disease flare,” he said.

Rounding off the session, Berit Flatø, MD, PhD, from Norway will present delegates with data from an epidemiological study of long-term outcomes of children with JIA as they move into adulthood.

“Dr. Flatø will present the long-term outcome data from children followed for up to 20 years,” Dr. Avcin said. “Biologics have been in pediatric rheumatology for around 17 years so we will be able to see what is the outcome of children with JIA moving into adulthood with our current treatment protocols.”

In the afternoon, on Friday, pediatric experts will team up with their adult rheumatology colleagues in a “challenges in clinical practice” session to update delegates on life-threatening presentations of rheumatic diseases.

“We will highlight life-threatening presentations that are of particular interest in children, like macrophage activation syndrome and complications of systemic connective tissue diseases and systemic vasculitides like Kawasaki disease and Takayasu’s arteritis,” Dr. Avcin said.
