[Chronic prurigo: overview of pathophysiology, diagnosis, and treatment].

BACKGROUND

Chronic prurigo (CPG) remains a challenging disease. Besides diagnosis, which mostly relies on the S2k-guideline diagnosis and treatment of chronic pruritus, two systemic agents have been approved for the treatment of CPG in recent years.

OBJECTIVES

This review aims to provide an overview of the pathophysiology and current diagnostic and therapeutic recommendations for CPG.

MATERIALS AND

METHODS

For this review, a literature and clinical trial search was conducted via PubMed and Clinical Trials using the terms 'chronic prurigo', 'prurigo nodularis', 'pathophysiology', 'diagnosis', 'treatment' and 'therapy'.

RESULTS AND

CONCLUSION

The pathophysiology of CPG is becoming increasingly well understood. Building on this, a second targeted therapy for patients with moderate to severe CPG has recently been approved. Numerous other substances are currently undergoing clinical trials, offering the prospect of further improvements in the care of patients affected by CPG.
