Hidradenitis suppurativa associated with pityriasis rubra pilaris

HIV-associated pityriasis rubra pilaris, or pityriasis rubra pilaris type VI, is a new entity reported in patients with HIV infection. HIV-associated pityriasis rubra pilaris is characterized by.. Studies evaluated the efficacy of IL-17 inhibitors for the following conditions: hidradenitis suppurativa (HS), pityriasis rubra pilaris (PRP), Behçet's disease, alopecia areata, and allergic contact dermatitis. Based on the available literature, secukinumab appears to be a potential treatment for HS, PRP, and Behçet's disease, while.

IL-17A is associated with the pathogenesis of inflammatory diseases, including psoriasis, atopic dermatitis, hidradenitis suppurativa, alopecia areata, pityriasis rubra pilaris, pemphigus, and systemic sclerosis. Interleukin-23 (IL-23) plays a pivotal role in stimulating the production of IL-17 by activating the Th17 cells. The IL-23/IL-17 axis is an important pathway for targeted therapy for inflammatory diseases HIV‐associated pityriasis rubra pilaris (PRP) or PRP type VI designates a new distinctive entity reported in HIV patients. It is characterized by cutaneous lesions of PRP and variable association with lesions of acne conglobata, hidradenitis suppurativa and lichen spinulosus

Pityriasis rubra pilaris (PRP) is a rare chronic papulosquamous disorder of keratinization, with an incidence between 1 in 5000 and 1 in 50000 with no gender predilection. 1 The pathogenesis is still unclear: it has been hypothesized that it is induced by an abnormal immune response toward different antigenic stimuli such as infections, trauma, and malignancy. 2,3 Most of the.

Abstract Topical use of immune response modifiers, such as imiquimod, has increased in dermatology. Although its topical use is well tolerated, it may be associated with exacerbations of generalized cutaneous inflammatory diseases, possibly through the systemic circulation of pro-inflammatory cytokines.

No method satisfies all requirements for the ideal treatment - quick healing, no hospital admission, minimal patient inconvenience and low recurrence - but greater awareness of the strengths and weaknesses of existing methods should lead to improved management Refractory pityriasis rubra pilaris (PRP) often is treated off-label with the same biologic therapies that are approved for the treatment of psoriasis, most commonly tumor necrosis factor (TNF) α antagonists and ustekinumab; however, the IL-17A antagonist secukinumab also has shown efficacy in the treatment of PRP.
