ABSTRACT
Background: actinic prurigo (AP) is a chronic, immune-mediated
photodermatosis associated with type iv hypersensitivity induced
by UV radiation. It predominantly affects indigenous and mestizo
populations in Latin America, with high prevalence in high-altitude
areas. Its pathophysiology involves CD4+ t lymphocytes and
HLA-DR4 expression. The objective of our review is to describe both
conventional and emerging treatments for AP, evaluating their published
efficacy and safety.
Methodology: a literature review was conducted in biomedical
databases, selecting observational studies, clinical trials, and
systematic reviews on the treatment of AP published in the last
20 years.
Results: conventional treatments, such as thalidomide and cyclosporine
a, have been effective but present significant adverse
effects. Newer approaches, such as JAK inhibitors (baricitinib) and
monoclonal antibodies (dupilumab), have shown better efficacy
and safety, although their access is limited.
Conclusions: biological therapies are emerging as promising
options for refractory AP, but their high cost and restricted availability
hinder their widespread application. Further studies are
required to optimize therapeutic strategies in vulnerable populations.
