Summary

Psoriasis is a chronic, recurring, immune-mediated papulosquamous condition The etiology of psoriasis is complex and not fully understood Though many treatment options are available for plaque psoriasis, each has its limitations and side effects. Therefore, the need for an effective topical agent that delivers the drug efficiently into the target site with minimal systemic side effects remains an aim in itself.Metformin is a derivative of biguanide that is the most widely used as an oral antihyperglycemic agent for the control of diabetes mellitus. In addition to its hypoglycaemic effect, metformin can serve as an anti-inflammatory agent. Metformin has been demonstrated to suppress proliferation in keratinocytes by blocking the mitogen-activated protein kinase pathway (MAPK) (25). Hence, metformin may play an important role in the reducing pathogenesis of psoriasis by anti-inflammatory, anti-proliferative, and anti- angiogenic effects .The topical form of metformin has been used in regenerative medicine (33), treatment of acne (34), adjuvant treatment for psoriasis (35), neo-adjuvant therapy for squamous cell carcinoma (36), and treatment of pigmentary disorders as an alternative to hydroquinone (37). The aim of the study is to: * Assess the efficacy and the safety of topical metformin 30% cream compared with betamethasone valerate 0.1 % cream in the treatment of adult patients with mild and moderate plaque psoriasis. * Compare the efficacy of topical metformin 30% cream versus betamethasone valerate 0.1 % cream clinically, dermoscopically, histopathologically and immunohistochemically by measuring tissue level of IL17 in psoriatic skin lesions before and after treatment in all patients.
