Behçet's syndrome: one year in review 2024

Area of Science:

• Rheumatology
• Immunology
• Genetics

Background:

• Behçet's syndrome (BS) is a complex inflammatory disorder with increasing incidence reported in some regions.
• Patient perspectives reveal significant impacts on quality of life, daily activities, and social interactions.
• Understanding the genetic underpinnings and inflammatory pathways is crucial for effective management.

Purpose of the Study:

• To critically review studies published in 2023 concerning Behçet's syndrome.
• To synthesize current knowledge on BS epidemiology, patient experiences, genetics, pathogenesis, and therapeutic advancements.

Main Methods:

• Literature review of studies published in 2023.
• Analysis of research on patient-reported outcomes, genetic associations, and molecular mechanisms.
• Evaluation of evidence for various therapeutic interventions.

Main Results:

• An increased incidence of BS was noted in Northern Spain post-2014.
• Genetic associations were identified between specific polymorphisms (HLA-B/MICA, SLCO4A1, DDX60L) and organ involvement (ocular, nervous system).
• Integrin α9β1 and PDL1/PD-1 pathways were implicated in BS pathogenesis, with potential roles for TNF inhibitors, TCZ, and JAK inhibitors in treatment.

Conclusions:

• Recent research deepens the understanding of BS genetics and inflammatory pathways.
• Evidence supports the efficacy of TNF inhibitors and suggests potential roles for TCZ and JAK inhibitors in managing BS organ involvement.
• Further research is needed to clarify the clinical implications of findings such as increased vein wall thickness.
