Aquagenic pruritus responding to intermittent photochemotherapy

Area of Science:

• Dermatology
• Photomedicine

Background:

• Aquagenic pruritus is a rare condition causing intense itching upon water contact.
• Symptoms occur without skin lesions or identifiable underlying causes.
• Current treatments, including antihistamines, are often ineffective.

Observation:

• A patient with typical aquagenic pruritus was treated with Psoralen-ultra violet A (PUVA) photochemotherapy.
• The patient experienced significant symptom relief following PUVA treatment.

Findings:

• PUVA photochemotherapy demonstrated high efficacy in managing aquagenic pruritus.
• Infrequent maintenance therapy was sufficient to control symptoms and prevent relapse.

Implications:

• PUVA offers a viable and effective treatment option for aquagenic pruritus.
• This approach may reduce the need for frequent, burdensome maintenance sessions.
• Further research into PUVA's long-term efficacy and optimal maintenance protocols is warranted.
