Alopecia areata (AA) is an immunologically mediated disease characterized by non-scarring hair loss (Madni and Shapiro, 2000). AA is presented by rapid and complete hair loss in one or more round or oval patches, usually on the scalp, beard area, eyebrows, eyelashes, and less commonly, on other hairy areas of the body (Berker et al., 2010 and James et al., 2011) Alopecia areata is a T-cell-mediated autoimmune disease. There is a complicated interplay between loss of immune privilege in the hair follicle, autoimmune-mediated hair follicle damage, and activation of inflammatory pathways that have been argued to explain the development of this disorder, but the exact pathophysiology of AA remains unknown. Hair follicles are infiltrated by autoreactive CD8 and CD4 T lymphocytes, which attack hair follicle-derived autoantigens while sparing the stem compartment (Rajabi et al., 2018). Alopecia areata can be treated with topical and/or intralesional corticosteroids, which are the treatment of choice. Anthralin, minoxidil, coal tar, and topical immunotherapy are examples of other topical treatments. Systemic immunosuppressants such as cyclosporine, systemic steroids, Janus kinase inhibitors, and methotrexate may be considered in severe resistant cases (lee and lee, 2017). Intralesional triamcinolone acetonide is preferred in cases of AA , as it is well known as anti-inflammatory and interferes with local immunity of the skin, which helps in the recovery of the disease, but if used in wrong technique or given in a high dose, it might cause all the side effects of corticosteroid, especially skin atrophy (Berker et al., 2010). Lactic acid is a member of alpha-hydroxy acids. It has been used in the treatment of many skin diseases, like AA and vitiligo. Lactic acid stimulates spontaneous secretion of vascular endothelial growth factor (VEGF) by human reconstructed epidermis. VEGF is an angiogenic cytokine involved in angiogenesis and wound healing and stimulates the growth of hair follicles resulting in recovery of AA. Other studies suggest that lactic acid may act through its irritant effect (Al-Tammimy, 2005). Vitamin D interacts with the innate and adaptive immune systems in a variety of ways, the majority of which contribute to its downregulation (Nancy and Yehuda, 2009). It has a powerful effect on T and B lymphocytes, influencing their activation responses (Arnson et al., 2007). All cells of the immune system express 1,25-dihydroxyvitamin D3 receptors (VDRs) and are therefore vulnerable to calcitriol-mediated modulation. Vitamin D3 has the ability to influence the migration and maturation of different dendritic cell subtypes and their production of chemokines and cytokines, giving them an immunoregulatory and tolerogenic role (Illescas-Montes et al., 2019) It has been shown that VDRs are highly expressed in the keratinocytes of human hair follicles and the absence of their expression is associated with reduced hair follicle growth and epidermal differentiation. Reduced VDR expression in the hair follicles of affected areas has also been observed in studies of AA patients' scalp (Çerman et al., 2015). Microneedling (MN) is a technique that comprises puncturing the skin repeatedly with sterile microneedles (Iriarte et al., 2017). It promotes hair regeneration by triggering stem cells in the hair bulge, which results in the generation of growth factors. It also improves blood circulation to the hair follicles and influences the local immune cells (Chandrashekar et al., 2014). Moreover, combining MN with applied topical drugs facilitates their absorption through the microchannels created within the epidermis (Fertig et al., 2018).
The objective of the study is to explore various clinical and biochemical parameters and their potential associations with disease severity, activity, and prognosis in atopic dermatitis, psoriasis, alopecia areata, and vitiligo. Further, the study aims at validating remote assessments of skin lesions, using smartphone-acquired photos. The study will also assess the feasibility and compliance with weekly remote-assessments and patient-reported data collection over the full study period of one year. The study will observe patients through a period of one year and will provide detailed information concerning the type and dose of medication used, as well as data to evaluate the disease activity with high resolution during this period. The study will involve collection of serum samples for exploratory biomarkers, and punch biopsies. A total of approximately 370 patients, divided into the four disease areas of atopic dermatitis, alopecia areata, psoriasis, and vitiligo, will be enrolled in the study. Using a combination of self-reported and on-site assessments and procedures, the intent is to observe the natural history of patients with select dermatological conditions, investigate tissue characteristics associated with disease activity and symptoms, and evaluate the validity of remote assessment of lesions, and feasibility of weekly self-acquired smart-phone images of skin lesions for remote assessment.
A multicenter prospective registry (STA2R) is conducted to assess systemic treatments for alopecia areata, focusing on effectiveness, safety, and long-term outcomes.
Artificial intelligence (AI) based on imaging holds tremendous potential to enhance visual diagnostic accuracy in the medical field. Amid the COVID-19 pandemic, limited access to in-person healthcare services drove shifts in medical care, hastening the adoption of telemedicine. In this context, AI usage for triage and decision support may be crucial for professionals to manage workload and improve performance. In dermatology, pigmented lesions, acne, and alopecia are three recurring pathology groups with high demand in dermatological centers. Both triage, clinical evaluation, and patient follow-up require in-person resources and specialist dedication. Employing tools like AI can benefit these professionals in reducing such processes and optimizing workload. Advancements in image recognition and interpretation, as well as in artificial intelligence, have spurred innovations in diagnosing various pathologies, including skin conditions. Computer-Aided Diagnosis (CAD) systems and other algorithm-based technologies have demonstrated the ability to classify lesion images with a competency comparable to that of an expert physician. In this study, the Legit.Health tool, developed by AI LABS GROUP S.L., which utilizes artificial intelligence to optimize clinical flow and patient care processes for skin conditions, will be evaluated. The purpose of this tool is to automatically prioritize patients with greater urgency, assign the type of consultation (dermatological or aesthetic), enhance diagnostic capability and detection of malignant pigmented lesions in auxiliary staff, and provide a visual record (photograph) of the condition for later review by external experts. Thus, the main objective of this study is to validate that Legit.Health, based on Artificial Intelligence, improves efficiency in clinical flow and patient care processes, thereby reducing time and cost of patient care through enhanced diagnostic accuracy and severity determination. The secondary objectives focus on measuring the diagnostic performance of Legit.Health: Demonstrate that Legit.Health enhances healthcare professionals' ability to detect malignant or suspicious pigmented lesions. Demonstrate that Legit.Health improves healthcare professionals' ability and precision in measuring the degree of involvement in patients with female androgenetic alopecia. Demonstrate that Legit.Health improves healthcare professionals' ability and precision in measuring the degree of involvement in patients with acne. Additionally, the study aims to assess the utility of this tool: Automate the triage/initial assessment process in patients presenting with pigmented lesions. Evaluate the reduction in healthcare resources usage by the center by reducing the number of triage consultations and directing the patient directly to the appropriate consultation (esthetic or dermatological). Evaluate Legit.Health's usability by the patient. Demonstrate that Legit.Health increases specialist satisfaction. Evaluate the reduction in healthcare resources usage by reducing the number of triage consultations and directing the patient directly to the appropriate consultation, whether in aesthetic or dermatological settings.

Alopecia areata (AA) an autoimmune disorder of hair follicles results in varying degrees of scalp, facial and body hair loss. Clinically, patients' presentation varies from patchy circumscribed scalp involvement to total body and scalp hair loss affects up to 2% of the general population. The exact pathobiology of AA has still remained elusive, while the common theory is the collapse of the immune privilege of the hair follicle caused by immunological mechanism. Multiple genetic, environment factors and psychological stress contribute to the pathogenesis of Alopecia Areata . Recent insights into the pathogenesis of AA have led to the development of new treatment strategies, such as Janus kinase inhibitors, biologics and several small molecular agents. In addition, modern therapies for AA, including antihistamines, platelet-rich plasma injection
