Overview

the aim of this study is to assess the efficacy and safety of sodium valproate-loaded nanospanlastic in the treatment of patchy AA, in comparison to conventional therapy with topical steroids

Alpopecia Areata (AA) is the second common cause of non-scarring hair loss, the disease has huge negative impact on patients' quality of life, social and psychological status. The underlying pathogenesis of AA is not fully characterized, Yet the collapse of immune privilege and generation of autoimmune attack against unknown follicular antigens are the most agreed-upon theories behind the disease. In spite of various therapeutic armamentariums available for AA, no single agent has been proven efficacious regarding reversing hair loss and establishing long-term response. keeping in mind the burden of the disease together with lacking effective treatments, a need for further therapies is colossal. Wnt-b catenin pathway is one of the crucial signalling pathways that regulate hair cycling. An increasing body of evidence is supporting the fact that wnt-b catenin pathway is inhibited in AA, and therefore contributing to the hair loss that characteize the disease. Sodium valproate (SV), a well-known anti-epileptic drug, was found to inhibit Glycogen synthase kinase-3beta (GSK3β) in neuronal cells as one of the possible antiepileptic mechanisms of SV. GSK3B is a well-known inhibitor of β-catenin activity in dermal papilla cells (DPCs), and thus induces catagen-like changes in these cells. So the idea of using topical SV to promote hair regrowth via activation of b catenin came up and attracted the interests of investigators. recently an optimized sodium valproate-loaded nanospanlastics topical formula promisingly achieved clinical equivalence with 5% minoxidil lotion in AGA, with a superior safety profile to minoxidil

Medical Language ↔ Plain English

Inclusion Criteria: * Patients with mild to moderate patchy alopecia areata, which is defined as less than 50% involvement of the entire scalp * Age above 12 years. * Both genders. * Patients with patchy alopecia areata, with 2 patches or more Exclusion Criteria: * Patients having single patch alopecia areata (at least 2 patches are required, as one patch will be left untreated to exclude the possibility of spontaneous remission) * Affection of more than 50% of the scalp area * Patients with alopecia totalis or universalis * Patients with ophiasis * Age: Less than 12 years old. * Pregnant or lactating females * Patients with history of or existing scalp skin diseases, infections or skin cancer * Severe systemic illness (as uncontrolled DM or hypertension, liver or renal diseases) and immune-compromised patients * Patients with concomitant autoimmune diseases as suspected by history or confirmed by previous investigations * Diagnosis or history of local dermatological disease in the scalp apart from AA such as eczema, seborrheic dermatitis, psoriasis. * Any psychiatric illness or psychological state impairing future compliance or influencing expectations of the patient

Outcomes

Primary Outcomes

- Treatment success

defined by achieving ≥ 50% reduction in baseline SALT score at end-of-study and/or achieving patient global assessment of improvement (PGAI) ≥ 50%.

Time frame: 6 months

Secondary Outcomes

molecular Assessment of treatment success rate of SV-loaded nanospanlastics in the treatment of mild to moderate patchy AA in comparison to conventional therapy with topical steroids

Assessment of expression of both beta-catenin and Axin2 in lesional scalp of patients with patchy AA before and after treatment with sodium valproate-loaded nanospanlastics, in comparison to conventional therapy with topical steroids

Time frame: 3 months

Dermoscopic evaluation of hair regrowth

This evaluation will determine the number of dystrophic hairs in the patch area at baseline to be compared after the end of treatment. Markers for dystrophic hairs include exclamation-mark hairs, black dots, yellow dots and pigtail regrowing hair. The percentage of dystrophic hairs will be evaluated on a four-point scale: 3, \> 50%; 2, 30-50%; 1, 1-29%; 0, no dystrophic hairs

Time frame: 3 months

Patient global assessment of improvement

Patient global assessment of improvement will be evaluated at the end of study, and will be scored as the following; (0 =no regrowth; 1 = \<25% of regrowth; 2 = 25%-49% of regrowth; 3 = 50%-74% of regrowth; 4 = 75%-99% of re- growth; 5 = 100% of regrowth)

Time frame: 3 months

Clinical satisfaction of each patient

Clinical satisfaction of each patient will be made using a 10-point visual analogue scale (VAS, 0-10; the 0 level was defined as "Not satisfied at all," while a level of 10 was defined as "completely satisfied")

Time frame: 3 months
