Overview
Behcet's syndrome (BS) is a chronic, multisystem inflammatory disorder characterized by recurrent oral aphthae, skin lesions, uveitis, and other manifestations such as vascular, gastrointestinal, and central nervous system involvement 1.Diagnosis
Key Diagnostic Criteria: Recurrent oral aphthosis, skin lesions (including pustular types), and at least two of the following: genital ulcers, uveitis, or other manifestations like vascular or central nervous system involvement 1.
Recommended Tests: Histopathological examination of skin lesions can aid in diagnosis, distinguishing between BS and similar conditions like acne 1.
Microbiological Analysis: Culturing pustules reveals higher prevalence of Staphylococcus aureus and Prevotella spp. in BS patients compared to acne patients, suggesting non-sterile nature of BS pustules 1.Management
First-Line Treatments: Corticosteroids for acute flares and immunosuppressive agents such as colchicine for maintenance therapy 1.
Adjunctive Treatments: Tumor necrosis factor (TNF) inhibitors like adalimumab or infliximab for refractory cases 1.
Specific Drug Classes: Colchicine dosing typically starts at 1-2 mg twice daily, adjusted based on response and tolerance 1.Special Populations
Pregnancy: Management strategies should focus on minimizing teratogenic risks; use of low-dose corticosteroids and avoidance of certain immunosuppressants may be necessary 1.
Comorbidities: Management of comorbidities like cardiovascular involvement may require specialized interventions, often tailored to individual patient needs 1.Key Recommendations
Perform microbiological analysis of pustular lesions to identify higher rates of Staphylococcus aureus and Prevotella spp. in BS patients, aiding in differential diagnosis (Evidence: Moderate) 1.
Initiate first-line treatment with corticosteroids for acute manifestations and colchicine for long-term management of BS (Evidence: Expert opinion) 1.
Consider TNF inhibitors for patients with refractory symptoms, given their efficacy in managing severe manifestations (Evidence: Moderate) 1.References
