What is "EULAR Recommendations for the Management of Behçet's Syndrome (2025 Update)"?

The EULAR Recommendations for the Management of Behçet's Syndrome: 2025 Update provide evidence-based guidance for diagnosing and treating Behçet's syndrome according to organ involvement. The guideline is intended for rheumatologists, ophthalmologists, dermatologists, internists, neurologists, gastroenterologists, trainees, and other healthcare professionals involved in multidisciplinary patient care.

Introduction

Behçet's syndrome is a complex multisystem inflammatory disease characterized by a relapsing-remitting course and the potential to affect virtually every organ system. Because disease manifestations range from recurrent oral ulcers to vision-threatening uveitis, vascular disease, neurological involvement, and gastrointestinal complications, treatment decisions must be individualized according to disease severity, affected organs, and patient-specific risk factors.

The EULAR Recommendations for the Management of Behçet's Syndrome: 2025 Update represent the latest consensus developed by an international multidisciplinary task force under the European Alliance of Associations for Rheumatology (EULAR). These updated recommendations integrate new evidence from randomized controlled trials, observational studies, and expert consensus to provide practical guidance for clinicians caring for patients with Behçet's syndrome.

Unlike traditional textbooks, this publication functions as an evidence-based clinical practice guideline. Rather than discussing disease mechanisms in depth, it focuses on treatment strategies, clinical decision-making, remission induction, maintenance therapy, and individualized management according to organ involvement.

For rheumatologists, ophthalmologists, dermatologists, neurologists, gastroenterologists, internists, residents, fellows, and other healthcare professionals, this guideline serves as an important reference for modern clinical practice.

What This Guideline Covers

A comprehensive evidence-based approach

The guideline updates previous EULAR recommendations using systematic literature reviews, expert consensus, and recently published clinical evidence. The task force reviewed studies published through November 2024 and developed recommendations following updated EULAR methodology.

The recommendations are organized according to organ involvement, reflecting the heterogeneous clinical presentation of Behçet's syndrome.

Major clinical domains include:

  • General principles of disease management
  • Mucocutaneous manifestations
  • Joint involvement
  • Ocular disease
  • Arterial disease
  • Venous thrombosis
  • Gastrointestinal involvement
  • Neurological disease
  • Quality indicators
  • Future research priorities

Overarching principles of management

A major strength of the guideline is its emphasis on five overarching principles that underpin all treatment decisions.

These principles emphasize that Behçet's syndrome:

  • follows a relapsing-remitting course;
  • may become organ- or life-threatening;
  • requires prevention of irreversible organ damage;
  • should be managed according to disease activity and prognostic factors;
  • benefits from multidisciplinary care, patient education, and shared decision-making.

The guideline also highlights that treatment should be individualized according to:

  • age,
  • sex,
  • disease duration,
  • affected organs,
  • disease severity,
  • patient preferences.

Evidence-Based Management of Mucocutaneous Disease

The guideline recommends colchicine as first-line therapy for recurrent mucocutaneous lesions because of its efficacy, tolerability, and affordability.

For patients whose disease remains active despite colchicine or who cannot tolerate it, the guideline recommends considering:

  • apremilast
  • TNF-α inhibitors

Topical glucocorticoids remain useful for oral and genital ulcers, while prolonged systemic glucocorticoid therapy is discouraged for isolated mucocutaneous disease because of long-term adverse effects.

The document also discusses additional therapeutic agents—including azathioprine, interferon-alpha (noting limited availability), ustekinumab, thalidomide, and dapsone—while clearly explaining the quality of supporting evidence and why some therapies are not preferred in routine practice.

Joint Involvement

For Behçet-related arthritis, colchicine continues to be recommended as first-line treatment.

In recurrent or chronic arthritis, immunosuppressive therapy may be considered. The guideline also discusses options such as azathioprine, TNF-α inhibitors, apremilast, glucocorticoids, intra-articular injections, and NSAIDs depending on the clinical scenario and available evidence.

Eye Disease: Protecting Vision

One of the most clinically important sections addresses Behçet uveitis.

The guideline emphasizes that:

  • all patients with Behçet uveitis require immunosuppressive therapy;
  • glucocorticoids should not be used as monotherapy;
  • patients with sight-threatening posterior uveitis should receive early treatment with monoclonal TNF-α antibodies, with infliximab preferred in combination with other immunosuppressive agents for severe posterior disease.

The document further discusses:

  • angiographic remission,
  • monitoring strategies,
  • long-term maintenance,
  • biologic therapy,
  • combination therapy,
  • areas where additional evidence is still needed.

Key Features

  • Evidence-based recommendations developed using updated EULAR methodology.
  • Recommendations organized according to organ involvement.
  • Based on systematic literature reviews and expert consensus.
  • Includes five overarching treatment principles.
  • Covers both remission induction and long-term maintenance strategies.
  • Incorporates recently published randomized controlled trials and observational studies.
  • Highlights multidisciplinary management.
  • Addresses quality of life alongside disease control.
  • Discusses quality indicators for healthcare delivery.
  • Identifies important priorities for future clinical research.

Why This Guideline Is Useful

One of the greatest strengths of the EULAR Recommendations for the Management of Behçet's Syndrome: 2025 Update is its practical, organ-based approach to treatment. 

Rather than recommending a single therapeutic pathway for all patients, the guideline recognizes the heterogeneous nature of Behçet's syndrome and emphasizes individualized treatment according to disease manifestations, prognostic factors, and patient preferences.

Strong Evidence-Based Foundation

The recommendations were developed using updated EULAR standard operating procedures and are supported by systematic literature reviews covering studies published through November 2024. 

Evidence was assessed using established methodological frameworks, and recommendations were refined through expert consensus involving an international multidisciplinary task force.

Clinically Practical

The guideline provides practical recommendations for:

  • First-line therapy
  • Escalation strategies
  • Biologic treatment
  • Glucocorticoid use
  • Maintenance therapy
  • Monitoring
  • Organ-specific management
  • Shared decision-making

This practical orientation makes it valuable for day-to-day clinical care rather than serving solely as an academic reference.

Focus on Organ Preservation

A recurring theme throughout the guideline is preventing irreversible organ damage. Early recognition of severe disease and prompt initiation of effective immunosuppressive therapy are emphasized, particularly for ocular, vascular, neurological, and gastrointestinal involvement.
