Cure8 research brief
Why This Matters
If confirmed, distinct circulating T- and B-cell patterns could help researchers and clinicians better understand immune differences in patients who have both ankylosing spondylitis and Crohn's disease, and could point toward biomarkers or pathways for future study.
Who Should Pay Attention
Researchers studying immune mechanisms in IBD and spondyloarthropathies, clinical immunologists, and clinicians caring for patients with overlapping AS and Crohn's disease presentations.

What To Know
The authors used flow cytometry on peripheral blood to profile lymphocyte populations in a small cohort (13 patients with AS+CD, 16 CD, 13 AS, and 26 healthy controls).
They report higher total regulatory T-cell levels and an increased frequency of CD73+ regulatory T cells within the effector-memory compartment in the AS+CD group compared with the other groups. Some effector-memory cytotoxic and helper T-cell populations were lower in AS+CD than in CD alone.
Correlations were reported between Tfh subsets and memory B-cell subsets and with inflammatory markers and disease activity scores. The study is a pilot with modest sample sizes and reports associations in peripheral blood; it does not establish causality or clinical diagnostic tests.
These findings are hypothesis-generating and may guide further research into immune biomarkers that differentiate AS+CD from AS or CD alone.
Keep In Mind
This report is a small pilot, based on peripheral blood flow-cytometry phenotyping; results are preliminary and intended to generate hypotheses for larger studies. The article content is an abstract-level summary from the journal Cells.

Genetic Susceptibility and Comorbidities in Psoriasis and HS
People with both psoriasis and hidradenitis suppurativa appear to have higher overall morbidity and a greater observed risk of Crohn’s disease. Genetic findings suggest shared biological pathways that could affect how...
Associations of polygenic risk scores with intestinal surgery, gastrointestinal cancer, and all-cause mortality in 5,021 individuals with inflammatory bowel disease
This paper explores whether polygenic risk scores (PRS) predict key long-term outcomes after IBD diagnosis — notably intestinal surgery — which could be relevant for risk stratification research and future clinical tools...

Genetic ancestry can influence IBD risk and disease course, and most prior studies focused on European populations.
