Abstract
Alopecia areata (AA) is an autoimmune disease characterized most commonly by patchy nonscarring hair loss which may progress to alopecia totalis which has poor prognosis. Platelet-rich plasma (PRP) therapy along with intralesional triamcinolone acetonide that is modified PRP proved to be beneficial in the case of alopecia totalis and helps in weaning patient off oral immunosuppression.

Abstract
Alopecia areata is an autoimmune hair loss disease that is non-scarring and is characterized by chronic inflammation at the hair follicle level. Clinically, patients' presentation varies from patchy, circumscribed scalp involvement to total body and scalp hair loss. Current management is guided by the degree of scalp and body involvement, with topical and intralesional steroid injections as primarily first-line for mild cases and broad immunosuppressants as the mainstay for more severe cases. Until recently, the limited number of blinded, randomized, placebo-controlled clinical trials for this disease had made establishing an evidence-based treatment paradigm challenging. However, growing insights into the pathogenesis of alopecia areata through blood and tissue analysis of human lesions have identified several promising targets for therapy. T-helper (Th) 1/interferon skewing has traditionally been described as the driver of disease; however, recent investigations suggest activation of additional immune mediators, including the Th2 pathway, interleukin (IL)-9, IL-23, and IL-32, as contributors to alopecia areata pathogenesis. The landscape of alopecia areata treatment has the potential to be transformed, as several novel targeted drugs are currently undergoing clinical trials. Given the recent US FDA approval of baricitinib and ritlecitinib, Janus kinase (JAK) inhibitors are a promising drug class for treating severe alopecia areata cases. This article will review the efficacy, safety, and tolerability of current treatments for alopecia areata, and will provide an overview of the emerging therapies that are leading the revolution in the management of this challenging disease.

Abstract
Alopecia areata (AA), a prevalent inflammatory cause of hair loss, lacks FDA-approved therapeutics for extensive cases, which are associated with very poor rates of spontaneous hair regrowth and major psychological distress. Current treatments for severe cases include broad immune-suppressants, which are associated with significant adverse effects, precluding long-term use, with rapid hair loss following treatment termination. As a result of the extent of the disease in severe cases, topical contact sensitizers and intralesional treatments are of limited use. The pathogenesis of AA is not yet fully understood, but recent investigations of the immune activation in AA skin reveal Th1/IFN-γ, as well as Th2, PDE4, IL-23, and IL-9 upregulations. Tissue analyses of both animal models and human lesions following broad-acting and cytokine-specific therapeutics (such as JAK inhibitors and ustekinumab, respectively) provide another opportunity for important insights into the pathogenesis of AA. As reviewed in this paper, numerous novel therapeutics are undergoing clinical trials for AA, emphasizing the potential transformation of the clinical practice of AA, which is currently lacking. Dermatologists are already familiar with the revolution in disease management of psoriasis, stemming from better understanding of immune dysregulations, and atopic dermatitis will soon follow a similar path. In light of these recent developments, the therapeutic arena of AA treatments is finally getting more exciting. AA will join the lengthening list of dermatologic diseases with mechanism-targeted drugs, thus changing the face of AA.

Abstract
BACKGROUND Severe alopecia areata (AA) is resistant to conventional treatment. Although systemic oral corticosteroids are an effective treatment for patients with severe AA, those drugs have many adverse effects. Corticosteroid pulse therapy has been introduced to increase therapeutic effects and reduce adverse effects. However, the treatment modality in severe AA is still controversial. OBJECTIVE To evaluate the effectiveness of corticosteroid pulse therapy in patients with severe AA compared with treatment with oral cyclosporine with corticosteroid. METHODS A total of 82 patients with severe AA were treated with corticosteroid pulse therapy, and 60 patients were treated with oral cyclosporine with corticosteroid. Both groups were retrospectively evaluated for therapeutic efficacy according to AA type and disease duration. RESULTS In 82 patients treated with corticosteroid pulse therapy, 53 (64.6%) were good responders (>50% hair regrowth). Patients with the plurifocal (PF) type of AA and those with a short disease duration (≤3 months) showed better responses. In 60 patients treated with oral cyclosporine with corticosteroid, 30 (50.0%) patients showed a good response. The AA type or disease duration, however, did not significantly affect the response to treatment. CONCLUSION Corticosteroid pulse therapy may be a better treatment option than combination therapy in severe AA patients with the PF type.

Abstract
Background. Alopecia areata (AA) has a significant impact on the quality of life and social interaction of those suffering from it. Our aim was to assess the impact of AA on the quality of life. Methods. Fifty patients diagnosed with AA seen in the Department of Dermatology of Hedi Chaker University Hospital, between March 2010 and July 2010, were included. Quality of life was measured by SF 36; severity of AA was measured by SALT. Results. Eighty percent had patchy alopecia with less than 50% involvement, 12% had patchy alopecia with 50-99% involvement, and 8% had alopecia totalis. Compared with the general population, AA patients presented a significantly altered quality of life, found in the global score and in five subscores of the SF-36: mental health, role emotional, social functioning, vitality, and general health. Gender, age, marital status, and severity of alopecia areata had a significant influence on patients' quality of life. Conclusions. This study indicates that patients with AA experience a poor quality of life, which impacts their overall health. We suggest screening for psychiatric distress. Studies of interventions such as counseling, psychoeducation, and psychotherapeutic interventions to reduce the impact of the disease may be warranted.

Abstract
Background Highly variable results of topical diphenylcyclopropenone (DPCP) in the treatment of alopecia areata have been reported so far. The purposes of the present study were to evaluate the efficacy and tolerability of DPCP treatment in severe alopecia areata. Methods Twenty-eight patients (16 female and 12 male, 10–35 years old, mean age 25 years) with extensive alopecia areata were enrolled in an open-label clinical trial. After sensitization with 2% DPCP, progressively higher concentrations beginning at 0.001% were applied weekly for 6 months to one side of the scalp, after which, if terminal hair growth was noted, the entire scalp was then treated under the same weekly protocol. The maximum concentration of DPCP in acetone was 2%. Results Twenty-seven of 28 patients completed therapy. The overall response rate was 81.5% (22/27), complete remission (90%-100% terminal hair re-growth) was obtained 22.2% (6/27) and partial remission (10%-90% terminal hair re-growth) in 59.3% (16/27). In all patients an eczematous reaction consisting of erythema, itching, and scaling at the site of application were observed. During therapy, other side effects including, occipital lymphadenopathy 40.7% (11/27), severe eczema/blister formation 40.7% (11/27), hyperpigmentation 18.5% (5/27) were observed, but no hypopigmentation, vitiligo, contact urticaria, and erythema multiforme-like reaction were seen in the patients. Nineteen of 27 (70.4%) patients had at least one side effect, other than eczematous reaction. Notably, partial recurrence was observed in 50.9% (13/22) of these patients after 6 to 12 months of follow-up. During the follow-up time the maintenance DPCP immunotherapy was continued. Conclusion Topical DPCP treatment for alopecia areata is an effective therapy with a slightly high relapse rate during bilateral maintenance treatment. According to the author's knowledge this is the first experience with DPCP in Iran.

Abstract
BACKGROUND The role of psychological factors in the pathogenesis of alopecia areata (AA) has long been the subject of debate. Numerous studies have provided controversial results. AIM This case-control study was undertaken to determine the significance of stressful life events and other psychological factors in the etiopathogenesis of AA. The impact of the disease on the quality of life was also assessed. METHODS Fifty-two adult patients (18 females and 34 males) diagnosed with AA and 52 age- and sex-matched individuals selected from hospital staff without any hair loss (control group) were evaluated using the major life events scale, Beck depression and Beck anxiety inventories, and the Short Form-36 health survey (SF-36). In addition, comparison was performed between two patient groups created according to whether or not they linked emotional trauma with their AA attack. RESULTS There was no statistically significant difference between the patient and control groups with regard to the total scores of stressful major life events, depression, and anxiety. Of the eight subscales on SF-36, vitality and mental health scores were higher in the control group, whereas social functioning scores were higher in the patients. The total number of stressful life events was higher in patients who attributed their disease to a stressful life event than in those who did not. CONCLUSIONS It appears unlikely that anxiety and depression play a major role in the etiopathogenesis of AA, but stressful life events may act as a trigger in the onset and/or exacerbation of the disease. Furthermore, AA seems to have a partly negative impact on the health-related quality of life.

Abstract
BACKGROUND Alopecia areata (AA) is suspected to be an autoimmune disease directed preferentially against hair follicles (HF) affecting both humans and various mammalian species. Recently, two rodent models of AA were described, namely the ageing C3H/HeJ mouse and the DEBR rat. Despite several case reports of canine AA in the literature, there has been no systematic assessment of the disease in these companion animals, and it is also not known whether dogs with AA could be useful as an outbred homologue of this disease in humans. OBJECTIVES To evaluate the clinical, histopathological and immunopathological features of 25 dogs with AA and compare these data with those found in the human disease. PATIENTS/METHODS Twenty-five client-owned dogs exhibiting macroscopic alopecia with peri- or intrabulbar lymphocytic infiltrates were selected for study. Biopsies and sera were obtained and assessed by histopathology, direct immunofluorescence of immunoreactant deposition, immunohistochemistry for lymphocyte markers, indirect immunofluorescence and immunoblotting analysis of circulating serum IgG, selective immunoprecipitation of HF proteins by serum IgG, and passive transfer of purified canine IgG into naïve C57BL/10 mice. RESULTS Clinical signs including alopecia, skin hyperpigmentation and leucotrichia usually developed during adulthood and were first seen on the face, followed by the forehead, ears and legs. Spontaneous remission of alopecia occurred in 60% of dogs and regrowing hair shafts were often non-pigmented. Histological examination of skin biopsy specimens revealed peri- and intrabulbar mononuclear cell infiltrates affecting almost exclusively anagen HF. Direct immunofluorescence analysis detected HF-specific IgG in 73% of dogs, while indirect immunofluorescence revealed circulating IgG autoantibodies to the HF inner and outer root sheaths, matrix and precortex. Immunoblotting analysis revealed IgG reactivity to proteins in the 45-60 kDa molecular weight range and with a 200-220 kDa doublet. The latter was identified as trichohyalin by selective immunoprecipitation. Purified HF-reactive IgG, pooled from AA-affected dogs, was injected intradermally to the anagen skin of naïve mice where it was associated with the local retention of HFs in an extended telogen phase in AA-treated skin compared with that seen in controls. CONCLUSIONS These findings are very similar to those reported for human AA patients; therefore, they support the consideration of dogs with AA as a useful homologue for the study of the pathogenesis of this common autoimmune disease of humans.

Abstract
BACKGROUND Alopecia areata is a burden for many patients and often resistant, even to extensive therapy. Orally administered PUVA therapy has been shown among numerous systemic and topical treatment modalities to be a therapeutic alternative. However, the clinical use of oral PUVA is often limited by systemic side effects. Bath-PUVA therapy offers an alternative solution because of the negligible systemic absorption of psoralen with this technique. Through use of a "PUVA-turban" it is now possible to administer a dilute bathwater solution containing 8-methoxypsoralen (8-MOP) to the scalp. OBJECTIVE The purpose of this study was to determine whether PUVA turban therapy is effective in treating alopecia areata in different clinical stages. METHODS We treated 9 patients with severe, rapidly progressing, treatment-resistant alopecia areata with PUVA-turban treatment as a modification of bath-PUVA therapy. At each treatment session a cotton towel was soaked with a 0.0001% 8-MOP solution (1 mg/L) at 37 degrees C, wrung gently to remove excess water, and wrapped around the patient's head in a turban fashion for 20 minutes. This was directly followed by UVA radiation. Treatment sessions were initially performed 3 to 4 times per week. RESULTS The cumulative UVA doses given over treatment periods of up to 24 weeks were 60.9 to 178.2 J/cm(2), with single doses ranging from 0.3 to 8.0 J/cm(2). After up to 10 weeks of treatment, hair regrowth could be noticed in 6 of 9 patients. Two patients did not respond to the treatment, and one patient showed only vellus hair regrowth. CONCLUSION PUVA-turban therapy can be considered a useful method of administering a dilute psoralen solution selectively to the scalp of patients. It has been shown to be a well-tolerated and, in some patients, efficient therapeutic alternative in the treatment of alopecia areata.

Abstract
Alopecia areata (AA) is a nonscarring hair loss condition. Among the many factors under investigation in the pathogenesis of AA, the main areas of concentration have been genetic constitution as well as nonspecific immune and organ-specific autoimmune reactions. Treatment with intralesional corticosteroid injections for localized patchy AA and topical immunotherapy for extensive AA have proven successful in the majority of patients, although all treatments are palliative and do not change the prognosis of the disease.

Abstract
Alopecia areata is a common form of non-scarring alopecia that appears equally in males and females of any age, although children and adolescents are more commonly affected. The disorder is usually characterized by limited alopecic patches on the scalp, but more severe forms may affect the entire scalp (alopecia totalis) or body (alopecia universalis). Characteristic nail changes may also accompany hair loss. Alopecia areata has been linked with certain human leukocyte antigen (HLA) class II alleles, indicating a probable autoimmune etiology. Current research implicates T lymphocytes in the pathogenetic mechanism of disease. Other autoimmune diseases are also linked with alopecia areata. The diagnosis of alopecia areata is usually made clinically, although a biopsy is diagnostic for this condition. Treatment is challenging and aims at the regrowth of hair in affected individuals. Intralesional corticosteroid injections are widely used in mild disease. Topical anthralin and minoxidil may also be clinically efficacious. Topical sensitizers, such as squaric acid dibutlyester and diphenyl-cyclopropenone, are sometimes employed. Various therapies for the disease may have efficacy in different patients, making a universal treatment algorithm difficult to implement. Patients should be handled on an individual basis, with the final outcome based on the cosmetic regrowth of hair. Maintenance therapy is also important in patients that do achieve acceptable regrowth, necessitating a highly motivated patient and good rapport with the treating physician.

Abstract
Although the results of some studies have proven negative, the influence of psychological factors in the development, evolution and therapeutic management of alopecia areata is, in general, well documented. Life events and intrapsychically generated stress can play an important role in triggering of some episodes. The comorbidity of psychiatric disorders, mainly generalized anxiety disorder, depression, and phobic states, is high. The role of treatment of concomitant psychopathological disorders is a vital one. Indeed this treatment can positively affect how the patient adapts to his/her alopecia and social setting and perhaps can even lead to a better dermatological evolution of the alopecia. Therefore, controlled studies analyzing the possible links between psychiatric symptoms, treatment with antidepressants or benzodiacepines, evolution of alopecia, medium term prognosis, and immune function are necessary. Basic psychotherapeutic support may prove to be of use in many cases and can be carried out by the dermatologist, although a subgroup of patients may need psychopharmacological or psychotherapeutic specialized treatments. Studies using operative diagnostic criteria and structured interviews are still scarce. Therefore, it seems necessary to design studies using modern psychiatric methodology. Controlled clinical trials to test the efficiency of psychoactive drugs and psychotherapy in the disease are also needed. By studying in depth these and other related aspects, we may improve the clinical management of our patients.

Abstract
The relationship between dental foci of infectious or mechanical nature and alopecia areata is analyzed through this case. There are many different causes for this dermatologic disease, and a dental origin seems to be very uncommon. Such a cause can only be confirmed a posteriori by a complete recovery of the patient after the dental cause is removed.

Abstract
Our 10-year experience with PUVA treatment for alopecia areata, partialis, totalis and universalis was retrospectively reviewed using charts and follow-up questionnaires for 70 patients at St John's Institute of Dermatology. In all cases, several previous therapies were judged to be unsatisfactory prior to starting PUVA, and many cases were already deemed clinically refractory prior to referral for PUVA. If cases of vellus hair growth are excluded, and those who lost their PUVA-induced regrowth rapidly on follow-up, the effective success rate was at best 6.3% for alopecia areata partialis, 12.5% for alopecia areata totalis and 13.3% for alopecia areata universalis. We affirm that PUVA is generally not an effective treatment for alopecia areata.
