Summary of "Role of Skin pH in Psoriasis."

Not much is known about the role of skin pH in skin pathophysiology, in particular in psoriasis. However, there is compelling evidence that the epidermal pH can influence the skin homeostasis and affect the skin barrier by changing the activity of cutaneous enzymes and through the modulation of skin inflammation and microbial colonization. This includes the activation of secretory phospholipase A and interaction with the peroxisome proliferators-activated receptor and retinoid pathways. In addition, pH in skin affects the activity of aquaporins and this controls the hydration of the epidermis. Changes in skin homeostasis, differentiation, barrier defects, and inflammation play a crucial role in the pathogenesis of psoriasis. There is evidence that skin pH can affect all of these important factors. However, more studies are needed to examine objectively and precisely the pH in the various skin layers in psoriatic lesional and non-lesional skin and compare it to normal skin. This additional know-how is essential to understand the role of skin pH in psoriasis with ultimately great potential of manipulations of skin pH for topical approaches in the management of psoriasis.

Medical and Biotech [MESH] Definitions

A common genetically determined, chronic, inflammatory skin disease characterized by rounded erythematous, dry, scaling patches. The lesions have a predilection for nails, scalp, genitalia, extensor surfaces, and the lumbosacral region. Accelerated epidermopoiesis is considered to be the fundamental pathologic feature in psoriasis.

A topical anti-inflammatory glucocorticoid used in DERMATOSES, skin allergies, PSORIASIS, etc.

A glucocorticoid used topically in the treatment of DERMATITIS; ECZEMA; or PSORIASIS. It may cause skin irritation.

An S100 calcium binding protein that contains two EF HAND MOTIFS and also binds zinc. It is secreted via a non-classical secretory pathway and expressed by KERATINOCYTES and epithelial cells of the tongue. It has antimicrobial and immunomodulatory activities and is highly expressed in the skin of patients with PSORIASIS, as well as in bladder and skin epithelial carcinomas.

A derivative of PREDNISOLONE with high glucocorticoid activity and low mineralocorticoid activity. Absorbed through the skin faster than FLUOCINONIDE, it is used topically in treatment of PSORIASIS but may cause marked adrenocortical suppression.
