Prurigo: diagnosis and management

Area of Science:

• Dermatology
• Immunology
• Pathophysiology

Background:

• Prurigo is characterized by intensely itchy, nodular skin lesions.
• While acute prurigo can stem from insect stings, subacute and chronic forms are often idiopathic.
• Various factors including toxins, UV light, and psychological influences can trigger or exacerbate prurigo.

Purpose of the Study:

• To provide a comprehensive overview of prurigo, encompassing its diverse etiologies.
• To detail the range of therapeutic interventions available for prurigo management.
• To highlight the complexity of treating therapy-resistant prurigo.

Main Methods:

• Literature review of prurigo causes and associated conditions.
• Compilation of current topical and systemic treatment modalities.
• Discussion of psychotherapeutic interventions and combined treatment strategies.

Main Results:

• Identified idiopathic, toxic, physical (UV light), and scratching-induced prurigo.
• Noted associations with atopy, pregnancy, internal diseases, and malignancy.
• Cataloged a wide array of treatments: topical (corticosteroids, UVB), systemic (PUVA, cyclosporine, dapsone), and psychotherapeutic agents.

Conclusions:

• Prurigo presents with varied triggers and associations, necessitating tailored treatment approaches.
• Effective management often requires a combination of therapies, including psychotherapeutic support.
• Addressing exacerbations and providing maintenance therapy are crucial for managing intractable itch in prurigo.
