5-Fluorouracil induces hair loss by inhibiting β-catenin signaling and angiogenesis

Chemotherapy-induced alopecia (CIA) is a side effect of the anticancer drug 5-fluorouracil (5-FU). However, the mechanism of action in hair follicle cells is unclear. This study investigated the mechanism of action of 5-FU on the hair cycle and growth in vitro and in vivo. Intraperitoneal injection of 5-FU into C57BL/6 mice delayed anagen initiation, resulting in small hair follicles. 5-FU inhibited angiogenesis by reducing cluster of differentiation 31+ cells, vascular endothelial growth factor, and fetal liver kinase-1 expression in mouse skin tissue and rat vibrissa dermal papilla (rDP) cells. 5-FU induced cell death in rDP cells and keratinocytes by enhancing cell cycle arrest or reducing the ratio of B-cell lymphoma 2 (Bcl-2) to Bcl-2-associated X levels. Immunoblotting and confocal microscopy showed that 5-FU inhibited the nuclear translocation of β-catenin in rDP cells and decreased fibroblast growth factor 7 and 10 secretion. Conversely, molecule-specific inhibitors did not prevent rDP cell death despite protein kinase B and Jun N-terminal kinase activation by 5-FU, indicating their indirect involvement. These results suggest that 5-FU inhibits wingless-related integration site/β-catenin signaling and angiogenesis, resulting in anagen-to-catagen transition and delaying anagen initiation. This study provides foundational data for developing treatments against CIA in patients with cancer undergoing 5-FU chemotherapy.

Comparing the efficacy of oral apremilast, intralesional corticosteroids, and their combination in patients with patchy alopecia areata: a randomized clinical controlled trial

INTRODUCTION

Alopecia areata (AA) is a chronic, immune-mediated inflammatory disorder characterized by nonscarring hair loss. The management of AA poses challenges due to its unpredictable course and variable response to treatment. In this comparative study, we evaluated the efficacy and safety of oral apremilast, intralesional corticosteroids (ILC) and a combination of both in patients with patchy AA.

METHODS

Sixty patients with patchy AA were randomly assigned to three treatment groups: oral apremilast (Group A), ILC (Group B), and a combination of both (Group C). The Severity of Alopecia Tool (SALT) score was used to assess the extent of hair loss before treatment, after 3 months, and at 6 months of follow-up. Adverse events and complications were also monitored. The changes in SALT score from baseline between the three groups were assessed by using non-parametric statistical tests. The statistical significance was judged at 5% level of significance.

RESULTS

Findings demonstrated significant higher reduction in median SALT scores after treatment i.e., 2.47 (1.76, 5.07), p < 0.001 as well as after six months follow up 5.08 (3.80, 7.53), p < 0.001 in patients treated with ILC compared to other two groups. Neither apremilast monotherapy nor its combination with ILC demonstrated statistically significant improvement, although individual responses were observed. Complications were minimal, with transient pain and burning sensation reported during ILC injections and a few cases of gastritis and relapse in the oral apremilast group.

CONCLUSION

These findings suggest that ILC remains an effective treatment option for patchy AA. This study did not demonstrate statistically significant efficacy of oral apremilast, either as monotherapy or in combination with ILC, though larger studies may be needed to evaluate potential benefits in specific patient subgroups. Further research with larger sample sizes and longer-term follow-up is needed to validate these findings and optimize treatment approaches for AA.

Epidemiology, Treatment Patterns, and Healthcare Resource Utilization Study of Patients With Alopecia Areata in Taiwan's National Health Insurance Research Database

OBJECTIVES

This study investigated the epidemiology, treatment patterns, and resource utilization in patients with alopecia areata (AA) in Taiwan using the National Health Insurance Research Database. AA severity was determined by treatment use and diagnostic codes in the year after enrollment (including corticosteroids, systemic immunosuppressants, topical immunotherapy, and phototherapy).

METHODS

The cross-sectional analysis was conducted to estimate the incidence and prevalence of AA from 2016 to 2020. For the longitudinal analysis, 2 cohorts were identified: mild/moderate and severe. The cohorts were matched based on age, gender, and comorbidities. Patients were enrolled upon their first claim with an AA diagnosis during the index period of 2017-2018.

RESULTS

The number of patients with AA increased from 3221 in 2016 to 3855 in 2020. The longitudinal analysis identified 1808 mild/moderate patients and 452 severe patients. Mild/moderate patients used higher levels of topical corticosteroids (82.41%) than severe patients (73.45%). Conversely, severe patients used more topical nonsteroids (41.81%) and systemic therapies (51.77%) than mild/moderate patients (0.44% and 16.15%, respectively). Oral glucocorticoids use was higher in severe patients (47.57%) relative to mild/moderate patients (14.88%), whereas the use of injectable forms was similar. The most used systemic immunosuppressants were methotrexate, cyclosporin, and azathioprine. Topical immunotherapy utilization decreased with subsequent treatment lines for severe patients. Treatment persistence at 6 months was low for all treatments. Severe patients had higher annual AA-related outpatient visits than the mild/moderate cohort.

CONCLUSIONS

These findings highlight the need for additional innovations and therapies to address the clinical and economic burden of AA.

Italian National Registry of Alopecia Areata: an epidemiological study of 699 Italian patients

BACKGROUND

Alopecia areata (AA) is an organ-specific autoimmune disease that affects the hair follicles of the scalp and the rest of the body causing hair loss. Due to the unpredictable course of AA and the different degrees of severity of hair loss, only a few well-designed clinical studies with a low number of patients are available. Also, there is no specific cure, but topical and systemic anti-inflammatory and immune system suppressant drugs are used for treatment. The need to create a global registry of AA, comparable and reproducible in all countries, has recently emerged. An Italian multicentric electronic registry is proposed as a model to facilitate and guide the recording of epidemiological and clinical data and to monitor the introduction of new therapies in patients with AA.

METHODS

The aim of this study was to evaluate the epidemiological data of patients with AA by collecting detailed information on the course of the disease, associated diseases, concomitant and previous events, and the clinical response to traditional treatments. Estimate the impact on the quality of life of patients.

RESULTS

The creation of the National Register of AA has proven to be a valid tool for recording, with a standardized approach, epidemiological data, the trend of AA, response to therapies and quality of life.

CONCLUSIONS

AA is confirmed as a difficult hair disease to manage due to its unpredictable course and, in most cases, its chronic-relapsing course, capable of having a significant impact on the quality of life of patients.

A Case Study of Stress-Induced Alopecia Areata Treated with Hominis Placenta Pharmacopunture

The purpose of this study is to report the clinical application of Hominis Placenta Pharmacopunture for Alopecia areata. Patient was diagnosed as stress-induced Alopecia areata 1 years ago. To reduce symptom, we treated a patient 8 times using Hominis Placenta Pharmacopunture. Hominis Placenta was injected subcutaneously into the lesion of head scalp alopecia. According to photographs, the lesion had been replaced with new terminal hair and the size of the lesion had decreased. This case has shown that stress-induced Alopecia areata patient could be treated by Hominis Placenta Pharmacopunture.

Development and Evaluation of Dutasteride Nanoemulgel for the Topical Delivery against Androgenic Alopecia

BACKGROUND

Dutasteride is approximately three times more potent than finasteride in treating alopecia. For reducing systemic exposure to dihydrotestosterone (DHT), researchers have shown special interest in developing topical formulations for treating androgenic alopecia. Dutasteride emulsification may lead to good skin penetration and improved availability in different lipophilic skin environments.

OBJECTIVES

This study aimed to encapsulate the drug into the lipidic carrier system for better local availability in the scalp skin, develop and evaluate nanoemulgel of dutasteride to ensure efficient topical administration, and perform the in-vivo activity of the developed gel for improved efficacy against alopecia.

METHODS

Dutasteride-loaded nanoemulsion was prepared by a high-speed homogenizer, followed by thickening of the dispersion using Carbopol 934. Skin permeation and accumulation were investigated in the excised skin of male Swiss albino mice. The nanoemulgel was characterized based on pH, stress stability, viscosity, and hardness.

RESULTS

The optimized dutasteride-loaded nanoemulsion had a size of 252.33 ± 8.59 nm, PDI of 0.205 ± 0.60, and drug content of 98.65 ± 1.78%. Stress stability was performed was well observed in nanoemulsion formulation. Nanoemulgel evaluation results were as follows: pH 5-6 was desirable for topical application, hardness was 43 gm, and spreadability was 79 gm with in vitro release of nanoemulgel at 91.98% and permeation study at 13.67%.

CONCLUSION

The in vivo studies demonstrated the growth of newer hair follicles and increased hair diameter and length in dutasteride-loaded nanoemulgel-treated alopecia animals compared to the marketed sample and testosterone-treated group. Provided with the same and long-term storage stability, the developed formulation is supposed to offer a good option for the topical administration of dutasteride in treating androgenic alopecia.

Alopecia Areata: Current Treatments and New Directions

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.

Diagnosis and Management of Alopecia Areata: A Saudi Expert Consensus Statement (2023)

Alopecia areata (AA) is a complex autoimmune disease manifesting as a chronic inflammatory disease characterized by non-scarring patches of hair loss over the face, scalp, and body. Several treatments have been proposed for AA, but none are curative nor achieve a state of remission. The present consensus statement aims to present the evidence- and experience-based recommendations on the diagnosis and management of AA in Saudi Arabia. The Ministry of Health in Saudi Arabia has opted to initiate a meeting of a multidisciplinary group to discuss and concede on this topic. Eight dermatology experts and clinical pharmacists convened in eight consensus meetings. All content presented in this document was agreed upon by this working group, including diagnosis and severity assessment, prognostic indicators, and therapeutic options for AA. Special consideration was given to special patient populations including pediatric patients and patients with less frequent presentations of AA. Updates of the current recommendations will take place as new evidence evolves in the treatment of AA.

Targetoid Hair Regrowth Pattern in Alopecia Areata: A Case Series

Alopecia areata (AA) is an autoimmune disorder leading to nonscarring hair loss of the scalp and/or body. Atypical hair regrowth in AA is considered a rare phenomenon. Many paradoxical forms of hair regrowth have been described in AA. Targetoid hair regrowth pattern in AA was first described in 1988. Here, we report three cases wherein this pattern of hair regrowth was seen.

Inheritance-Specific Dysregulation of Th1- and Th17-Associated Cytokines in Alopecia Areata

Autoimmune diseases tend to cluster in families, suggesting genetic predisposition to autoimmunity associated with familial background. We have previously reported similarities in gene expression patterns and PTPN22 polymorphisms between alopecia areata (AA) patients and their healthy relatives, but not unrelated healthy controls. However, the spectrum of disease promoting (or preventing) pathways that may be activated in blood relatives of AA patients remains to be defined. Here, we investigated the extent to which cytokines associated with the Th1 and Th17 pathway are differentially expressed in the blood of patients with AA and its clinical subtypes in comparison to both healthy relatives as well as unrelated healthy controls. A comprehensive set of Th1- and Th17-related cytokines were evaluated by ELISA. We found a significant elevation of the Th17 inducer IL-23, the Th17 product IL-17A, the Th1 hallmark cytokine IFNγ, and TNFα, a Th1 cytokine with relevance to the Th17 pathway in AA patients, regardless of disease subtype, compared to healthy individuals. On further examination, we found that healthy family members grouped together with patients in terms of elevated Th1- and Th17-pathway cytokines in an inheritance-specific manner, distinct from unrelated controls. The elevation of Th17-associated cytokines in healthy controls related to AA patients indicates that Th1 and Th17 dysregulation in AA may be genetically based. Of note, one unrelated control displayed elevated levels of IL-17A and IL-23 similar to those detected in patients. One year after initial blood draw, areas of beard hair loss consistent with the diagnosis of AA were reported by this individual, indicating that the elevation in Th17-related cytokines may have predictive value.

Trichoscopy pattern in alopecia areata: A systematic review and meta-analysis

BACKGROUND

The incidence of alopecia areata (AA) has increased over the last few decades. Trichoscopy is a noninvasive procedure performed in dermatology clinics and is a helpful tool in determining the correct diagnosis of hair loss presentations.

OBJECTIVE

Through mapping the researches that have been done to represent the spectrum of trichoscopic findings in AA and to identify the most characteristic patterns.

METHODS

Thirty-nine studies were eligible for the quantitative analysis. Meta-analysis and subgroup analysis were performed.

RESULTS

Thirty-nine studies (29 cross-sectional, five retrospective, two descriptive, one case series, one observational, and one cohort) with a total of 3204 patients were included. About 66.7% of the studies were from Asia, 25.6% from Europe, and 7.7% from Africa. The most characteristic trichoscopic findings of AA were as follows; yellow dots, black dots, broken hairs, short vellus hairs, and tapering hairs.

CONCLUSION

There is no single pathognomonic diagnostic trichoscopic finding in AA rather than a constellation of characteristic findings. The five most characteristic trichoscopic findings in AA are: yellow dots, black dots, broken hairs, short vellus hairs, and tapering hairs. Yellow dots and short vellus hairs considered the most sensitive clues for AA, while black dots and tapering hairs are the most specific ones. Furthermore, trichoscopy is a useful tool that allows monitoring of response during the treatment of AA. Treatment responded cases will show an increase in short vellus hairs, but loss of tapering hairs, broken hairs, and black dots, while yellow dots are the least responsive to the treatment.

A phase 2a randomized vehicle-controlled multi-center study of the safety and efficacy of delgocitinib in subjects with moderate-to-severe alopecia areata

Alopecia areata/AA is an autoimmune cause of nonscarring hair loss. The pathogenesis of AA involves many immune axes, including Th1/Th2 pathways. Delgocitinib is a pan-Janus kinase/JAK inhibitor that broadly blocks pro-inflammatory cytokines and has been effective in other inflammatory skin conditions. Recent human studies/reports have shown that use of some systemic JAK inhibitors led to hair regrowth, suggesting this medication class as a potential therapy for AA. However, topical treatment is desirable due to potential systemic side effects. To assess the efficacy and safety of topical delgocitinib in AA, we conducted a double-blind, randomized, vehicle-controlled clinical trial in 31 moderate-to-severe AA patients that were randomized 2:1 to receive delgocitinib ointment 30 mg/g (n = 20) or ointment vehicle (n = 11) for 12 weeks. The primary endpoint was change in severity of Alopecia Tool/SALT score from baseline to week 12. The secondary endpoint included safety profile by reported adverse events. Twenty-three subjects completed the trial, with eight discontinuing mostly due to voluntary withdrawal. Ten patients receiving delgocitinib ointment and three patients receiving vehicle showed SALT score improvements after 12 weeks, but the mean percent SALT improvement at week 12 compared to baseline between the two arms was not significant (p = 0.92). Our study suggests that delgocitinib ointment is not effective in moderate-to-severe AA, likely due to its inability to penetrate sufficiently deeply into the dermis of the scalp, but larger studies are necessary to assess whether a different formulation of topical JAK inhibitors may be suitable to treat mild or more localized forms of AA.

An Updated Review on Current Treatment of Alopecia Areata and Newer Therapeutic Options

Alopecia areata (AA) is a dermatological disease that causes nonscarring hair loss. It can occur at any age and has an unpredictable and variable evolution in individuals. The aim of this review is to provide an update on the novel therapies currently being used, as well as upcoming therapeutic options in the treatment of AA.

Repurposing levocetirizine hydrochloride loaded into cationic ceramide/phospholipid composite (CCPCs) for management of alopecia: central composite design optimization, in- silico and in-vivo studies

Levocetirizine hydrochloride (LVC) is an antihistaminic drug that is repurposed for the treatment of alopecia. This investigation is targeted for formulating LVC into cationic ceramide/phospholipid composite (CCPCs) for the management of alopecia. CCPCs were fabricated by ethanol-injection approach, through a central composite experiment. CCPCs were evaluated by inspecting their entrapment efficiency (EE%), polydispersity index (PDI), particle size (PS), and zeta potential (ZP). The optimum CCPCs were additionally studied by in-vitro, ex-vivo, in-silico, and in-vivo studies. The fabricated CCPCs had acceptable EE%, PS, PDI, and ZP values. The statistical optimization elected optimum CCPCs composed of 5 mg hyaluronic acid, 10 mg ceramide III, and 5 mg dimethyldidodecylammonium bromide employing phytantriol as a permeation enhancer. The optimum CCPCs had EE%, PS, PDI, and ZP of 88.36 ± 0.34%, 479.00 ± 50.34 nm, 0.377 ± 0.0035, and 20.20 ± 1.13 mV, respectively. The optimum CCPC maintained its stability for up to 90 days. It also viewed vesicles of tube shape via transmission electron microscope. The in-silico assessment resulted in better interaction and stability between LVC and vesicle components in water. The ex-vivo and in-vivo assessments showed satisfactory skin retention of LVC from optimum CCPCs. The histopathological assessment verified the safety of optimum CCPCs to be topically applied. Overall, the optimum CCPCs could be utilized as a potential system for the topical management of alopecia, with a prolonged period of activity, coupled with reduced LVC shortcomings.

No increased risk of alopecia in ankylosing spondylitis patients: A population-based cohort study in Taiwan

AIM

To investigate the association between ankylosing spondylitis (AS) and alopecia.

METHODS

In this cohort study, data from over 1 000 000 patients in the Taiwan Longitudinal Health Insurance Database were extracted. We selected newly diagnosed (outpatient department visit three or more times or admission at least once) patients with AS (ICD-9-CM = 720.0) from 2000 to 2012. For the non-AS comparison group, patients never diagnosed with AS were chosen from 1999 to 2013. In all, 3640 AS patients and 14 560 non-AS controls were selected. Cox proportional hazard model and Kaplan-Meier analysis were used to present the results. The adjusted hazard ratio (HR) in the Cox proportional hazard model was adjusted for age, sex, hypertension, hyperlipidemia, diabetes, atopic dermatitis, and mental disorder.

RESULTS

No increased risk of alopecia in AS patients was shown in the Cox proportional hazard model (crude HR 1.16, P = 0.595; adjusted HR 1.16, P = 0.599). Negative results are found as well in subgroup analysis of different age, sex (age 20-40 y: HR 1.03, P = 0.925; Age ≥40 y: HR 1.49, P = 0.406; Female: HR 1.17, P = 0.759; Male: HR 1.15, P = 0.667), and phenotypes of alopecia (androgenetic alopecia: HR 1.19, 95% confidence interval [CI] 0.58-2.41; alopecia areata: HR 0.98, 95% CI 0.37-2.62). A significant positive correlation is found between atopic dermatitis and alopecia (adjusted HR 8.05, P = 0.039).

CONCLUSION

In this population-based cohort study, we found no association of risk of alopecia and AS.

A Comprehensive Review of Natural Alternatives for Treatment of Alopecia with an Overview of Market Products

Alopecia or hair loss is a widespread issue that has significant effects on personal well-being for both genders nationally and internationally. In addition, alopecia causes extreme emotional stress and negatively impacts the psychological health and self-esteem of cancer patients suffering from chemotherapy-induced alopecia. Unfortunately, available synthetic medications are costly, invasive, or have extreme adverse effects. On the contrary, natural and herbal hair loss products are widely available in the local and international markets in variable pharmaceutical forms with different mechanisms of action, namely, androgen antagonists, nutritional supplements, vasodilators, and 5α-reductase inhibitors or dihydrotestosterone blockers. Thus, it is of great importance to encourage researchers to investigate these natural alternatives that can act as potent therapeutic agents having diverse mechanisms of action as well as limited side effects. Currently, natural remedies are considered a fast-rising pharmaceutical segment with demand from a wide range of consumers. In this study, we present a review of reported herbal remedies and herb combinations recommended for hair loss and their mode of action, along with an overview of available market products and formulations, their composition, and declared effects. In addition, a general outline of the different forms of alopecia, its causes, and recommended treatments are mentioned as well. This was all done with the aim of assisting further studies with developing standardized natural formulations for alopecia as many were found to lack standardization of their bioactive ingredients and efficiency confirmation.

Platelet Rich Plasma and Its Use in Hair Regrowth: A Review

Platelet rich plasma (PRP) was described as a small volume of plasma containing higher concentrations of platelets than those found in peripheral blood and initially used as a transfusion product for treatment of thrombocytopenia. To date, it was discovered that there are several growth factors and cytokines that can accelerate wound healing and tissue regeneration, leading to a wider range of applications in the medical field, such as in sport medicine, regenerative medicine, and aesthetic medicine. Several studies have shown that PRP can be used effectively for treatment of hair loss. Although it has been widely used, the exact mechanism of action of PRP is still not fully elucidated. In this article, we aim to review and update current information on the definition, classification, mechanism of action, clinical efficacy in hair regrowth, and adverse events of PRP.

Comparative study of the use of fractional co2 laser versus the use of Liquid Nitrogen Cryotherapy In the treatment of Alopecia Areata in a sample of the Egyptian population

BACKGROUND

Alopecia areata (AA) is an autoimmune disease that is represented as patches of hair loss, FractionalCo2 laser and Cryotherapy are used to stimulate hair growth in patients of AA.

AIM

evaluation of fractional co2 laser effect versus liquid nitrogen cryotherapy in the treatment of Alopecia Areata.

METHODS

Eighty patients presented with patches of AA. The first group consisted of 40 patients was treated with fractional co2 laser, the second group also 40 patients was treated with cryotherapy. The efficacy of the treatment was statistically evaluated.

RESULTS

A positive therapeutic response was noted in most patients By trichoscopy at the end of treatment, there was a decrease in exclamation mark hairs, yellow dots, black dots, broken hairs, and an increase in short vellus hair and circle hair of patients compared to baseline and control. No serious side effects were seen.

CONCLUSION

Fractional co2 laser and Liquid nitrogen cryotherapy is considered a promising, safe, and effective treatment modality with the better result with co2 laser.

Superficial cryotherapy versus intralesional corticosteroids injection in alopecia areata: A trichoscopic comparative study

Background:

Alopecia areata (AA) is an autoimmune disease leading to noncicatricial alopecia. Topical or intralesional corticosteroid (ILCS) is the accepted therapeutic option for mild cases; however, adverse effects are sometimes difficult to reverse. When the exposure to liquefied nitrogen is limited to a few seconds “superficial” cryotherapy, reactive vasodilation may improve microcirculation and nutritional status around hair follicles.

Objective:

This study aimed to evaluate and compare superficial cryotherapy and ILCS in the treatment of patchy AA.

Materials and Methods:

This prospective comparative study included 21 patients with patchy AA. Every patient received superficial cryotherapy on one patch, every 2 weeks for 3 months, and ILCS injection for another patch, once monthly for 3 months.

Results:

Clinical improvement was higher in cryotherapy group compared to ILCS group with a statistically significant difference (P = 0.002). On trichoscopic evaluation, terminal hair count was improved in lesions treated with cryotherapy more than lesions treated with ILCS but without statistical significance (P = 0.595) and vellus hair count was improved in lesions treated with cryotherapy more than lesions treated with ILCS with a statistical significance (P = 0.002).

Conclusions:

Cryotherapy is more effective and less painful than ILCS in the treatment of patchy AA.

Lesson to Learn From Cellular infiltrate in Scalp Biopsy of Alopecia Areata

BACKGROUND

Alopecia areata (AA) is a common cause of hair loss. It is mediated by T lymphocytes. Scalp biopsy findings in AA differ according to the disease phase and activity.

OBJECTIVES

To study the cellular infiltrate in the transverse section of scalp biopsy of AA at different disease stages and in relation to disease activity.

METHODS

The study was performed on 40 subjects with AA. A 4-mm punch biopsy was obtained from an AA scalp lesion. Biopsies were sectioned horizontally; 2 anatomical levels were studied (mid dermal and deep dermal levels).

RESULTS

Ninety-five percent of AA showed noncicatrical alopecia. A significant relation was found between the course of AA and the terminal:vellus ratio. Peribulbar lymphocytic infiltration was seen in 70% of cases. Mast cells were observed in 87.5% of cases, including fibrous tract and around the arrector pili muscles. Eosinophils were detected in the scalp biopsy of 22.5% of cases. Course and activity of AA were significantly related to the peribulbar lymphocytic cell infiltration but not to mast cells and eosinophils.

CONCLUSION

Although a peribulbar lymphocytic infiltrate is the classical finding of AA, it is absent in the chronic phase. Mast cells are commonly found in the scalp biopsy of AA and could explain the potential therapeutic effect of antihistamines.

Validation of the Alopecia Areata Patient Priority Outcomes (AAPPO) Questionnaire in Adults and Adolescents with Alopecia Areata

Introduction

Individuals with alopecia areata (AA) may experience significant impacts on their health-related quality of life. The novel Alopecia Areata Patient Priority Outcomes (AAPPO) questionnaire has been developed to assess hair loss signs, emotional symptoms, and activity limitations associated with AA. The objective of this study was to evaluate psychometric properties and establish scoring of the AAPPO in adults and adolescents with AA.

Methods

Scoring and measurement properties of the AAPPO were examined using baseline and 2-week follow-up data from a prospective, noninterventional, web-based study of 121 patients with AA (85 adults aged ≥ 18 years, 36 adolescents aged 12–17 years) with Severity of Alopecia Tool (SALT) ≥ 25% scalp hair loss.

Results

Exploratory and confirmatory factor analysis supported four single Hair Loss (HL) items, an Emotional Symptoms domain (ES; 4 items), and an Activity Limitations domain (AL; 3 items). Among all patients, the multi-item ES and AL domains had strong internal consistency (α ≥ 0.87); all HL items and domain scores had strong test-retest reliability (weighted kappa or intraclass correlation coefficients ≥ 0.78). All HL item scores demonstrated strong construct validity (r ≥ 0.52) compared with the patient-reported Alopecia Areata Symptom and Impact Scale (AASIS) hair loss subscale score; ES and AL domain scores exhibited strong construct validity (r ≥ 0.66) compared with the SF-36 Mental Component Summary (MCS) score. Using SALT scores, HL mean item scores were better (lower) in the 25–49% SALT subgroup versus those with highest SALT scores (76–100%); however, ES mean domain scores were better in the SALT 76–100% subgroup in the same comparison (p < 0.0001). Using AASIS and MCS score–created subgroups, ES and AL mean domain scores demonstrated hypothesized differences across subgroups (all p values < 0.0001).

Conclusion

The AAPPO questionnaire is a reliable, valid disease-specific measure of hair loss severity and impact in individuals with AA.

Epidemiology, management and the associated burden of mental health illness, atopic and autoimmune conditions, and common infections in alopecia areata: protocol for an observational study series

INTRODUCTION

Alopecia areata (AA) is a common cause of immune-mediated non-scarring hair loss. Links between AA and common mental health, autoimmune and atopic conditions, and common infections have previously been described but remain incompletely elucidated and contemporary descriptions of the epidemiology of AA in the UK are lacking.

METHODS AND ANALYSIS

Retrospective study series using a large population-based cohort (5.2 million) from the Oxford Royal College of General Practitioners (RCGP) Research and Surveillance Centre (RSC) database, exploring four themes: AA epidemiology, mental health comorbidities, autoimmune/atopic associations and common infections.In the epidemiology theme, we will describe the incidence and point prevalence of AA overall and by age, sex and sociodemographic factors. Healthcare utilisation (primary care visits and secondary care referrals) and treatments for AA will also be assessed. In the mental health theme, we will explore the prevalence and incidence of mental health conditions (anxiety, depressive episodes, recurrent depressive disorder, adjustment disorder, agoraphobia, self-harm and parasuicide) in people with AA compared with matched controls. We will also explore the mental health treatment patterns (medication and psychological interventions), time off work and unemployment rates. Within the autoimmune/atopic associations theme, we will examine the prevalence of atopic (atopic dermatitis, allergic rhinitis, asthma) and autoimmune conditions (Crohn's disease, ulcerative colitis, coeliac disease, type 1 diabetes, Hashimoto's thyroiditis, Graves' disease, rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, systemic lupus erythematosus (SLE), polymyalgia rheumatica, Sjögren's syndrome, psoriasis, vitiligo, multiple sclerosis, pernicious anaemia) in people with AA compared with matched controls. We will also estimate the incidence of new-onset atopic and autoimmune conditions after AA diagnosis. Within the common infections theme, we will examine the incidence of common infections (respiratory tract infection, pneumonia, acute bronchitis, influenza, skin infection, urinary tract infection, genital infections, gastrointestinal infection, herpes simplex, herpes zoster, meningitis, COVID-19) in people with AA compared with matched controls.

ETHICS AND DISSEMINATION

The Health Research Authority decision tool classed this a study of usual practice, ethics approval was not required. Study approval was granted by the RCGP RSC Study Approval Committee. Results will be disseminated through peer-reviewed publications.

Is the severity of initial sensitization to diphenylcyclopropenone in alopecia areata patients predictive of the final clinical response?

Immunotherapy by diphenylcyclopropenone (DPCP) is generally started with 2% DPCP sensitization, however in recent years studies have questioned the necessity of sensitization that may cause patients severe reactions and troubles at the onset of therapy. The purpose of the present study was to evaluate the association between the severity of initial reaction to 2% DPCP sensitization in AA patients and clinical response. In this retrospective study, 110 AA patients who continued therapy for at least 6 months were enrolled. Hair loss and hair regrowth rates were calculated based on the Severity of Alopecia Tool (SALT) scoring system. Initial reaction to 2% DPCP sensitization after 2 weeks was graded as negative reaction (absence of any reaction), doubtful reaction (mild erythema, pruritus, and irritation for minutes after test), weak (erythema, mild edema, and scaling), and strong to extreme reaction (vesicles, bullae, ulcer, and discharge). The degrees of the initial reaction to 2% DPCP after 2 weeks were negative reaction 13 (11.81%), doubtful reaction 40 (36.36%), weak reaction 33 (30%), and strong to extreme reaction 24 (21.81%). Patients were divided into two groups: (A) patients with less than 12-month therapy (75 of 110), (B) patients with more than 12-month therapy (35 of 110). Initial reaction to 2% DPCP sensitization was not correlated with hair regrowth rate in either group (group A: Spearman's rho = 0.194, p = 0.095; group B: Spearman's rho = 0.063 p = 0.720). After 12-month treatment with DPCP, hair regrowth rate was significantly greater than 6-months therapy (group A: 17.03 ± 37.78, group B: 49.26 ± 36.34; p = 0.003). The severity of hair loss at the onset of treatment was significantly associated with the response rate in both groups (p-value <0.002). Based on our results, it is the initial severity of the disease and not the initial reaction to 2% DPCP sensitization that predicts the clinical response to DPCP immunotherapy.

Potential of nanoparticulate based delivery systems for effective management of alopecia

In recent times, more than 50 % of the global population is facing hair-related issues (alopecia) which is seen mostly amongst the people in the age group of 30-40 years. The conventional topical dosage forms available in the market falls short in effectively managing alopecia. Despite various advancements in topical dosage forms, it is still disposed to limited clinical application and provides poor penetration of drug molecules into the skin. The exact etiology of alopecia is still unknown and various researchers link lifestyle, hereditary, and auto immune-based events with its existence. Nanoparticulate-based delivery are hence brought in use to enhance the permeability properties of the drug. In comparison to conventional methods nanotechnology-based drug delivery system tames drug molecules to a specific site with much better efficacy. This review is engrossed in the journey and role of nano technological-based drug delivery in the management of alopecia and its clinical application.

Ginsenoside Rg4 Enhances the Inductive Effects of Human Dermal Papilla Spheres on Hair Growth Via the AKT/GSK-3β/β-Catenin Signaling Pathway

Ginsenoside Rg4 is a rare ginsenoside that is naturally found in ginseng, and exhibits a wide range of biological activities including antioxidant and anti-inflammatory properties in several cell types. The purpose of this study was to use an in vivo model of hair follicle (HF)-mimic based on a human dermal papilla (DP) spheroid system prepared by three-dimensional (3D) culture and to investigate the effect of Rg4 on the hair-inductive properties of DP cells. Treatment of the DP spheroids with Rg4 (20 to 50 μg/ml) significantly increased the viability and size of the DP spheres in a dose-dependent manner. Rg4 also increased the mRNA and protein expression of DP signature genes that are related to hair growth including ALP, BMP2, and VCAN in the DP spheres. Analysis of the signaling molecules and luciferase reporter assays further revealed that Rg4 induces the activation of phosphoinositide 3-kinase (PI3K)/AKT and the inhibitory phosphorylation of GSK3β, which activates the WNT/β-catenin signaling pathway. These results correlated with not only the increased nuclear translocation of β-catenin following the treatment of the DP spheres with Rg4 but also the significant elevation of mRNA expression of the downstream target genes of the WNT/β-catenin pathway including WNT5A, β-catenin, and LEF1. In conclusion, these results demonstrated that ginsenoside Rg4 promotes the hair-inductive properties of DP cells by activating the AKT/GSK3β/β-catenin signaling pathway in DP spheres, suggesting that Rg4 could be a potential natural therapy for hair growth.

Efficacy and predictive factors of cyclosporine A in alopecia areata: a systematic review with meta-analysis

INTRODUCTION

Drugs for alopecia areata (AA) can induce hair regrowth, but do not change the disease course. Dual properties of cyclosporine A (CsA) as hypetrichotic and immunosuppressive agent have encouraged use in AA. We aimed to determine the most meaningful efficacy of CsA and reveal features helping enhance its efficacy and reduce relapses.

METHOD

Efficacy of CsA and predictive factors were investigated. Cochrane, MEDLINE, Pubmed and Embase databases were searched.

RESULTS

2,189 papers were retrieved. Based on 344 patients, mean proportion of responders was 73%. CsA monotherapy showed proportion of hair regrowth of 66%, whereas CsA combined with systemic corticosteroids yielded 78%. Overall efficacy in studies with duration of CsA treatment <6 months was: 74% (53-88%), while in those with duration ≥6 months was: 73% (47-89%). Recurrence with CsA monotherapy was 55% (6-96%) whereas when CsA was combined with systemic corticosteroids it was 28% (6-72%).

CONCLUSION

CsA confers a favorable therapeutic effect and concomitant use of steroids slightly enhances efficacy, but it dramatically decreases relapses. Longer treatments seem to lead to less relapse likelihood, but daily dose does not influence recurrence. Optimal CsA dosage is 5 mg/kg/day in single therapy regimen, whereas it is 3 mg/kg/day in the steroid-associated regimen. KEY POINTSWhat is already known about this subject? Most treatments for alopecia areata have not been critically evaluated. Current outcomes about the efficacy and relapse rate of cyclosporine A (CsA) are inconsistent and predictive factors about the clinical response are lacking.What this study adds? CsA confers a favorable therapeutic hair regrowth. Longer treatment seems to lead to less likelihood of relapse of AA, but the daily dose does not exert any effect on the recurrence of the disease. The concomitant use of corticosteroids broadly decreases relapses, and it also enhances efficacy.Impact on clinical practice The combination with corticosteroids is the most predictive feature to prevent relapse of AA, followed by the duration of CsA therapy. The daily dose of CsA is the feature with the least or null impact on the clinical course of AA.

The association between alopecia areata and anxiety, depression, schizophrenia, and bipolar disorder: a population-based study

Although Alopecia areata (AA) has been found to be associated with psychological distress, the scope and nature of this association has not been fully delineated. The current study sought to examine the association of AA with anxiety, depression, schizophrenia, and bipolar disorder, utilizing a large-scale matched controlled cohort design. Patients suffering from AA (n = 41,055) were matched to control cases (n = 41,055) by age, sex, and socioeconomic status (SES). The prevalence of the four major mental disorders was assessed while stratifying the sample by age and sex, and after adjusting for marital status, smoking, BMI, hypertension, and diabetes. Data were accessed via the Clalit Health Services (CHS) database, a comprehensive health registry utilized by the largest managed healthcare company in Israel. Anxiety was independently and positively associated with AA (OR 1.22, 95% CI 1.13-1.31, p < 0.001), across all age groups above 30, with similar rates in males and females. Depression was also independently and positively associated with AA (OR 1.09, 95% CI 1.01-1.17, p < 0.005), particularly in the 30-49 age group, with a higher association among females. A negative association was found between AA and schizophrenia (OR 0. 71, 95% CI 0.61-0.83, p < 0.001). No association was found between AA and bipolar disease. Patients with AA are at risk for anxiety and depression, with female patients, and patients in the 30-49 age group being particularly vulnerable to develop a co-occurring mental disorder. Medical treatment should therefore include psychiatric evaluation and appropriate care.

Alopecia treatment using minimally manipulated human umbilical cord-derived mesenchymal stem cells: Three case reports and review of literature

BACKGROUND

Alopecia areata (AA) is a common autoimmune disease characterized by hair loss. AA appears in extensive forms, such as progressive and diffusing hair loss (diffuse AA), a total loss of scalp hair (alopecia totalis), and complete loss of hair over the entire body (alopecia universalis). Recently, mesenchymal stem cells (MSCs) have been identified as a therapeutic alternative for autoimmune diseases. For this reason, preclinical and case studies of AA and related diseases using MSCs have been conducted.

CASE SUMMARY

Case 1: A 55-year-old woman suffered from AA in two areas of the scalp. She was given 15 rounds of minimally manipulated umbilical cord-MSCs (MM-UC-MSCs) over 6 mo. The AA gradually improved 3 mo after the first round. The patient was cured, and AA did not recur. Case 2: A 30-year-old woman, with history of local steroid hormone injections, suffered from AA in one area on the scalp. She was given two rounds of MM-UC-MSCs over 1 mo. The AA immediately improved after the first round. The patient was cured, and AA did not recur. Case 3: A 20-year-old woman, who was diagnosed with alopecia universalis at the age of 12, was given 14 rounds of MM-UC-MSCs over 12 mo. Her hair began to grow about 3 mo after the first round. The patient was cured, and alopecia universalis did not recur.

CONCLUSION

MM-UC-MSC transplantation potentially treats patients who suffer from AA and related diseases.

Immune-related cutaneous adverse events due to checkpoint inhibitors

OBJECTIVE

To familiarize the reader with the most common cutaneous adverse events with immune checkpoint inhibitors (CPIs) and their grading and treatment.

DATA SOURCES

Recent research articles, relevant review articles, and case series/reports in English from the PubMed database mostly, from 2010 onward.

STUDY SELECTIONS

Most data are from retrospective studies and case series. Older studies regarding the mechanism were included if they were of particular importance.

RESULTS

An understanding of this review should enable the reader to identify specific skin disorders in patients receiving immune CPIs, grade the adverse event, and be able to treat or refer the patient as needed.

CONCLUSION

Allergists/immunologists need to be familiar with these immune-related cutaneous adverse events because their incidence will increase with the ever-expanding use of CPIs and, in particular, because patients will certainly continue to be referred suspecting drug allergies.

A randomized comparative study of the efficacy of topical latanoprost versus topical betamethasone diproprionate lotion in the treatment of localized alopecia areata

BACKGROUND

Topical corticosteroids are the standard therapy for the treatment of alopecia areata. Recently, topical latanoprost has been found effective in the treatment of eyelash alopecia areata.

OBJECTIVES

The objective of this study was to compare the efficacy of topical latanoprost ophthalmic solution (group 1) with that of topical betamethasone diproprionate lotion (group 2) in the treatment of localized alopecia areata.

METHODS

This was a single-centre, randomized, two-armed, parallel-group efficacy trial. Fifty consecutive patients with localized alopecia areata were randomized in a 1:1 ratio to receive either topical latanoprost 0.005% ophthalmic solution or topical betamethasone diproprionate 0.05% lotion. Of these 50 patients, 44 patients (21 in group 1 and 23 in group 2) completed the treatment protocol.

RESULTS

The percentage reduction in area involved with alopecia areata at 16 weeks (primary outcome) was lower in latanoprost vs. betamethasone group (median [interquartile range], 11.1 [0-99.1] vs. 100% [13.6-100], P = 0.02). Significantly lesser patients in the latanoprost group had a complete response to treatment as compared to the betamethasone group (6 [24%] vs. 14 [56%], P = 0.02). The median (interquartile range) hair regrowth score was significantly lower in the latanoprost vs. the betamethasone group (1 [0-4.5] vs. 5 [1-5], P = 0.02). Subjects in the betamethasone group showed a more rapid reduction in the involved area.

LIMITATIONS

Short duration of treatment and follow-up were limitations of this study.

CONCLUSION

Our results suggest that topical latanoprost 0.005% ophthalmic solution is less effective but safer than topical betamethasone dipropionate 0.05% lotion in the treatment of localized alopecia areata (clinicaltrials.gov: NCT02350023).

Therapeutic implications of psychological state in patients with alopecia areata: A qualitative study

Hair loss can significantly impact an individual's psychological state, self-image, and can lead to numerous personal, social, and occupational problems. Although these impairments are well documented in primary studies and reviews, and the need for appropriate psychological help is emphasized, there is still a lack of knowledge for a broader and specific picture. The patient's perspective is vital while seeking to understand the content of the variables like "impaired body image" or "low self-esteem." This article advocates the need for studies involving methodologies allowing to explore the complexity and depth of experience. A better understanding of patients' states, reactions, and needs might contribute to the practice of healthcare professionals seeking the best possible help. This study aimed to explore the lived experience of people with alopecia areata in Lithuania using a phenomenological approach. Experiences of six patients with varying degrees of alopecia areata, four women and two men (mean age 27 years), were explored. Data were obtained using an unstructured interview and were analyzed based on Colaizzi's phenomenological approach. This article explores findings related to patient's psychological state covering two superordinate themes: (a) devastating loss of perceived self and (b) grieving and the process of acceptance. The insights for the appropriate therapeutic intervention were formulated.

Platelet-Rich Plasma in the Treatment of Alopecia Areata: A Review

Platelet-rich plasma (PRP) is an autologous preparation of plasma with concentrated platelets containing various growth factors and cytokines that enhance the body's inherent capacity to repair and regenerate hair follicles. A few studies and case reports support the use of PRP for the treatment of alopecia areata (AA). Further large-scale studies are needed to evaluate the efficacy of PRP as monotherapy or in association with other therapeutic modalities for AA. Although PRP is relatively safe and potentially effective, there is no standardized protocol or recommendations for the number of PRP sessions required to treat and maintain hair growth.

Alopecia in Children Following Living Related Liver Transplantation

INTRODUCTION

Alopecia is a common complication in patients following kidney transplantation; however, reports regarding liver transplantation patients are still few.

METHODS

This study followed 111 children who underwent living related liver transplantation. Alopecia patients and its possible risk factors were analyzed.

RESULTS

Alopecia occurred in 3 patients (2.7%). Underlying diseases were biliary atresia and Alagille syndrome. Clinically significant alopecia (universal alopecia) occurred in 1 patient with Alagille syndrome. All patients received tacrolimus as their immunosuppression drug. None of the patients who received cyclosporine experienced alopecia. The onset of alopecia ranged from 7 to 28 months after transplantation. Alopecia was treated with a topical corticosteroid and topical tacrolimus, but 1 patient with clinically severe alopecia required conversion from tacrolimus to cyclosporine A.

CONCLUSIONS

Alopecia is 1 complication seen in children receiving tacrolimus therapy following living donor liver transplant. Prompt management of this cosmetic complication should be done to ensure patients' compliance to medication regimen.

Childhood Alopecia Areata: An Overview of Treatment and Recent Patents

BACKGROUND

Alopecia Areata (AA) is a systemic autoimmune condition that usually starts in childhood.

OBJECTIVE

This article aims to review genetics, therapy, prognosis, and recent patents for AA.

METHODS

We used clinical queries and keywords "alopecia areata" AND "childhood" as a search engine. Patents were searched using the key term "alopecia areata" in Patents.google.com and freepatentsonline. com.

RESULTS

Due to an immune-mediated damage to the hair follicles, hair is lost from the scalp and other areas of the body temporarily or even permanently. Children with AA are generally healthy. Evidence of genetic association and increased predisposition for AA was found by studying families with affected members. Pathophysiologically, T- lymphocytes attack hair follicles and cause inflammation and destruction of the hair follicles and hair loss. In mild cases, there would be well-demarcated round patchy scalp hair loss. The pathognomonic "exclamation mark hairs" may be seen at the lesion periphery. In more severe cases, the hair loss may affect the whole scalp and even the whole body. The clinical course is also variable, which may range from transient episodes of recurrent patchy hair loss to an indolent gradually deteriorating severe hair loss. The treatment of AA depends on factors including patients' age, the extent of the hair loss, duration of disease, psychological impact, availability and side effect profile of the treatments. For localized patchy alopecia, topical application of corticosteroids and/or intralesional corticosteroids are the treatment of choice. Other topical treatments include minoxidil, anthralin, coal tar and immunotherapy. In severe resistant cases, systemic immunosuppressants may be considered. Although herbal medicine, acupuncture, complementary and alternative medicine may be tried on children in some Asian communities, the evidence to support these practices is lacking. To date, only a few recent patents exist in topical treatments, including Il-31, laser and herbal medications. Clinical efficacy is pending for these treatment modalities.

CONCLUSION

None of the established therapeutic options are curative. However, newer treatment modalities, including excimer laser, interleukin-31 antibodies and biologics, are evolving so that there may be significant advances in treatment in the near future. AA can be psychosocially devastating. It is important to assess the quality of life, degree of anxiety, social phobia and mood of the patients and their families. Psychological support is imperative for those who are adversely affected psychosocially.

Meta-Analysis on the Efficacy and Safety of Traditional Chinese Medicine as Adjuvant Therapy for Refractory Androgenetic Alopecia

Objective

Traditional Chinese medicine (TCM) therapies have been widely used for the treatment of androgenetic alopecia (AGA) for thousands of years. We conducted a meta-analysis to evaluate the curative efficacy and safety of TCM for treating AGA.

Methods

Randomized controlled trials (RCTs) of TCM for the treatment of AGA through March 2019 were systematically identified in 4 English databases, namely, PubMed, Cochrane Library, EMBASE, and Web of Science, and 4 Chinese databases, namely, Sino-Med, China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP), and WanFang. Quality assessment and data analysis were performed by Review Manager 5.3.5, and Stata 15.1 was used to cope with publication bias.

Results

30 RCTs involving 2615 patients were randomly divided into a TCM group and a conventional medicine (CM) group. The results showed that the total efficacy rate (TER) of the TCM group was significantly higher than that of the control group (OR = 3.34, 95% CI = 2.75–4.05, P < 0.00001). The total symptom score (TSS) of the TCM group was markedly reduced when compared with the CM group (SMD = −0.86; 95% CI = −1.19, −0.53; P < 0.00001). The microelement levels (Fe²⁺, Zn²⁺, and Cu²⁺) in hair were significantly improved when complemented with TCM therapy. In addition, no significant differences were observed between the two groups in terms of adverse events (OR = 0.55, 95% CI = 0.29–1.05, P=0.07).

Conclusions

In view of the effectiveness and safety of TCM, the present meta-analysis suggests that TCM could be recommended as an effective and safe adjuvant therapy for the treatment of AGA by improving the TER, symptoms, serum testosterone levels, and microelement levels. However, long-term and higher-quality RCTs are needed to overcome the limitations of the selected studies and more precisely interrogate the efficacy and safety of TCM.

Italian Guidelines in diagnosis and treatment of alopecia areata

Alopecia areata (AA) is an organ-specific autoimmune disorder that targets anagen phase hair follicles. The course is unpredictable and current available treatments have variable efficacy. Nowadays, there is relatively little evidence on treatment of AA from well-designed clinical trials. Moreover, none of the treatments or devices commonly used to treat AA are specifically approved by the Food and Drug Administration. The Italian Study Group for Cutaneous Annexial Disease of the Italian Society of dermatology proposes these Italian guidelines for diagnosis and treatment of Alopecia Areata deeming useful for the daily management of the disease. This article summarizes evidence-based treatment associated with expert-based recommendations.

Hierarchy of hair loss stigma: media portrayals of cancer, alopecia areata, and cancer in Israeli newspapers

BACKGROUND

Over 300,000 people in Israel cope with temporary or permanent hair loss (alopecia) that results from diseases and medical treatments. For women, hair loss can be a highly traumatic event that may lead to adverse psychosocial consequences and health outcomes. Nevertheless, this phenomenon has been mostly ignored by health professionals as it is primarily considered an aesthetic-rather than as a health-related issue. Only recently the Healthcare Basket Committee approved financial assistance for the purchase of wigs by patients coping with hair loss. Given the important role that the media plays in shaping health policies related to diagnoses, treatment and support services, the current study sought to enrich our understanding of how the media portrays disease-related hair-loss.

METHODS

Using framing and agenda-setting theories, this study examined the media portrayals of hair loss associated with three diseases-cancer, alopecia areata, and ringworm, depicted in Israeli newspapers in 1994-2016. The sample consisted of 470 articles about the three diseases: 306 on cancer, 36 on AA, and 128 on ringworm.

RESULTS

Textual and visual analysis revealed the ways media marginalize this physical flaw. Cancer was framed in medical terms, and patients were portrayed as older Israeli-born people whose hair loss was absent from their experience. Ringworm was framed as a fear-inducing disease; patients were portrayed as faceless, unidentified immigrants that coped with visible hair loss. Articles on AA provided the greatest focus on the patient's experience of hair loss, but patients were portrayed as young foreign people.

CONCLUSIONS

Our results revealed a hierarchy of stigmas against hair loss, in which the media coverage marginalized this experience. The omission of hair loss by the media may explain, at least in part, why health professionals often ignore the psychosocial needs of these patients. Health insurance funding of wigs is a helpful but nevertheless insufficient solution to coping with feminine hair loss. Our findings may encourage media leaders to conduct planned media interventions to increase awareness of clinicians and health policymakers about the unique challenges faced by women coping with hair loss and promote health policy-making aimed at the well-being of these women.

Investigating the beneficial experiences of online peer support for those affected by alopecia: an interpretative phenomenological analysis using online interviews

BACKGROUND

Those affected by alopecia are at risk of experiencing a range of psychosocial consequences. Alopecia UK provides online peer support via facilitated Facebook pages. Online peer support has been found to provide a variety of benefits in other long-term conditions, such as providing information and emotional support.

OBJECTIVES

This study sought to gain an experiential account as to how online support provides benefit to people living with alopecia.

METHODS

A purposive sample of 12 participants was recruited directly from Alopecia UK's Facebook group. A total of 11 were diagnosed with alopecia and one participant was a family member of someone with alopecia. The qualitative approach of Interpretative Phenomenological Analysis was used to guide data collection and analysis. Participants took part in online synchronous interviews, which drew on review of participant-selected screenshots of online activity.

RESULTS

Four themes were identified, including 'gradual healing', 'image concern', 'belonging' and 'new identity and self-acceptance'. The participants made use of the group through expressing emotion, finding practical advice, and also as a place to connect and share experiences. Participants also reported that the online support facilitated the return of social confidence.

CONCLUSIONS

This study provides a detailed understanding as to how online peer support groups can be beneficial. Online groups have the potential to create a feeling of belonging, which can develop a sense of being accepted and understood and as such can be important in maintaining psychological well-being. The findings indicate that online groups have the potential to be used as a platform for assisting people in developing both effective coping styles and feeling understood, and such platforms warrant further investment by healthcare professionals. What's already known about this topic? Alopecia may be associated with psychosocial distress due to both the individual impact and the reactions of others. Online peer support is known to be a beneficial method of providing psychosocial support for people living with a range of health conditions. What does this study add? An in-depth view of the benefits experienced through belonging to an online peer support group for those diagnosed with alopecia, in addressing the psychosocial effects experienced with the condition. This research highlights the need for further investigation of the utility of supporting the development of online peer support for people living with skin conditions. Online peer support groups could be highly effective to use in combination with existing psychological therapies to connect others with shared experience. What are the clinical implications of this work? People living with alopecia can benefit from peer support, and healthcare professionals should ensure that patients know where they can gain access to both psychological support and peer support.

Topographic Phenotypes of Alopecia Areata and Development of a Prognostic Prediction Model and Grading System: A Cluster Analysis

Importance

Diverse assessment tools and classification have been used for alopecia areata; however, their prognostic values are limited.

Objective

To identify the topographic phenotypes of alopecia areata using cluster analysis and to establish a prediction model and grading system for stratifying prognoses.

Design, Setting, and Participants

A retrospective cohort study of 321 patients with alopecia areata who visited a single tertiary referral center between October 2012 and February 2017 and underwent 4-view photographic assessment.

Exposures

Clinical photographs were reviewed to evaluate hair loss using the Severity of Alopecia Tool 2. Topographic phenotypes of alopecia areata were identified using hierarchical clustering with Ward's method. Differences in clinical characteristics and prognosis were compared across the clusters. The model was evaluated for its performance, accuracy, and interobserver reliability by comparison to conventional methods.

Main Outcomes and Measures

Topographic phenotypes of alopecia areata and their major (60%-89%) and complete regrowth probabilities (90%-100%) within 12 months.

Results

A total of 321 patients were clustered into 5 subgroups. Grade 1 (n = 200; major regrowth, 93.4%; complete regrowth, 65.2%) indicated limited hair loss, whereas grades 2A (n = 66; major regrowth, 87.8%; complete regrowth, 64.2%) and 2B (n = 20; major regrowth, 73.3%; complete regrowth, 45.5%) exhibited greater hair loss than grade 1. The temporal area was predominantly involved in grade 2B, but not in grade 2A, despite being comparable in total extent of hair loss. Grade 3 (n = 20; major regrowth, 45.5%; complete regrowth, 25.5%) included diffuse or extensive alopecia areata, and grade 4 (n = 15; major regrowth, 28.2%; complete regrowth, 16.7%) corresponded to alopecia (sub)totalis. No significant differences in prognosis (hazard ratio [HR] for major regrowth, 0.79; 95% CI, 0.56-1.12) were found between grades 2A and 1, whereas grades 2B (HR, 0.41; 95% CI, 0.21-0.81), 3 (HR, 0.24; 95% CI, 0.12-0.50), and 4 (HR, 0.16; 95% CI, 0.06-0.39) had significantly poorer response. Among multiple models, the cluster solution had the greatest prognostic performance and accuracy. The tree model of the cluster solution was converted into the Topography-based Alopecia Areata Severity Tool (TOAST), which revealed an excellent interobserver reliability among 4 dermatologists (median quadratic-weighted κ, 0.89).

Conclusions and Relevance

Temporal area involvement should be independently measured for better prognostic stratification. The TOAST is an effective tool for describing the topographical characteristics and prognosis of hair loss and may enable clinicians to establish better treatment plans.
