What is the management approach for a patient with Behçet's disease who presents with balanitis?

Management of Balanitis in Behçet's Disease

Balanitis (genital ulcers) in Behçet's disease should be treated with topical corticosteroids for symptomatic relief and colchicine 1-2 mg/day as first-line systemic therapy, with escalation to azathioprine or immunosuppressives if lesions are severe, recurrent, or causing scarring. 1, 2

Initial Management Approach

First-Line Therapy

• Apply topical corticosteroids directly to genital ulcers for immediate symptomatic relief 1, 2
• Start colchicine 1-2 mg/day as the preferred systemic agent, which has proven efficacy in randomized controlled trials specifically for genital ulcers and is particularly effective in women 1, 3

When to Escalate Treatment

Escalate to immunosuppressive therapy if:

• Genital ulcers are causing scarring or deformity 2
• Lesions are severe, frequent, or significantly impacting quality of life 1, 2
• Patient fails to respond adequately to colchicine within 2-3 months 1

Second-Line Immunosuppressive Options

• Azathioprine is the preferred steroid-sparing immunosuppressive for mucocutaneous involvement 1, 2
• Alternative agents include cyclophosphamide or cyclosporine-A for refractory cases 1
• Consider monoclonal anti-TNF antibodies (infliximab or adalimumab) for severe refractory genital ulcers that fail conventional immunosuppressives 1, 3

Critical Clinical Considerations

Risk Stratification

• Young males with early disease onset require more aggressive treatment and closer monitoring due to higher risk of severe disease progression 2, 4, 3
• Genital ulcers can cause irreversible scarring and obliterative/deforming anatomical damage if undertreated, making early aggressive management essential in high-risk patients 2

Additional Therapeutic Options

• Lactobacilli lozenges may be considered as a safe alternative based on uncontrolled observational evidence, though this is primarily studied for oral ulcers 1
• IL-1 blockade (anakinra, canakinumab) may provide partial benefit for mucocutaneous involvement in refractory cases 1

Important Pitfalls to Avoid

• Never use IL-6 blockade (tocilizumab) for mucocutaneous lesions, as it has been shown to worsen these manifestations 1
• Do not delay immunosuppression in patients with frequent scarring ulcers, as this can result in permanent anatomical damage 2
• Avoid cyclosporine-A if the patient has any history of neurological involvement, even if currently inactive, due to neurotoxicity risk 4, 3

Long-Term Management Strategy

• Treatment intensity should be weighed against the burden of mucocutaneous lesions versus the risk of adverse drug reactions, as genital ulcers cause quality of life impairment but typically do not cause life-threatening complications 1, 2
• Disease manifestations often ameliorate over time, allowing for potential treatment tapering in stable patients 2, 3
• Maintain close follow-up to monitor for development of major organ involvement (ocular, vascular, neurological, gastrointestinal), which would require immediate aggressive immunosuppression 2, 3
