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

Comparing quality of life, anxiety, depression, sleep disturbance, and associated factors in vitiligo and alopecia areata patients

INTRODUCTION AND OBJECTIVES

Vitiligo and alopecia areata (AA) are two autoimmune skin diseases that affect patients' quality of life (QoL) and give rise to psychosocial complications, such as depression, negative self-image, less joyful social engagements, and low self-esteem. These two disorders have common and uncommon characteristics. Therefore, in this study, we tried to evaluate the similarities and differences in the psychological parameters including quality of life, sleep disturbance, anxiety, and depression levels between, vitiligo and AA patients.

MATERIALS AND METHODS

Patients with either vitiligo or AA visiting the outpatient dermatology clinic from November 2017 to December 2020 have been included in this study. Persian versions of three questionnaires including the dermatology life quality index (DLQI), hospital anxiety and depression scale (HADS), and Pittsburgh sleep quality index (PSQI), have been used to assess the QoL, sleep disturbance, anxiety, and depression levels in patients.

RESULTS

In total, 188 patients, including 94 (50%) cases of AA and 94 (50%) patients with vitiligo, met the criteria. In AA patients, a significantly higher DLQI score was found (p-value = 0.002) compared to the vitiligo cases, which means a better QoL in vitiligo patients. Additionally, AA patients had higher scores of anxiety (P-value<0.001) and depression (p-Value<0.001). However, sleep disturbance (64.9% of AA patients vs. 59.3% of vitiligo patients; p-Value = 0.4888) was not significantly different between the two groups.

CONCLUSIONS

Our data showed lower QoL and higher levels of anxiety and depression in AA patients compared to vitiligo cases, but no difference was seen in sleep disturbance in the PSQI-P score.

Platelet-rich plasma efficacy in alopecia areata patients with normal and elevated levels of antibodies against thyroglobulin and thyroid peroxidase

AIM

To evaluate and compare the efficacy of platelet-rich plasma (PRP) therapy in alopecia areata (AA) patients with normal and with elevated levels of anti-thyroglobulin antibodies and/or anti-thyroid peroxidase antibodies.

Adverse event reporting of four anti-Calcitonin gene-related peptide monoclonal antibodies for migraine prevention: a real-world study based on the FDA adverse event reporting system

Background: Anti-Calcitonin gene-related peptide monoclonal antibodies (anti-CGRP mAbs) have shown significant efficacy in preventing migraine. However, there have been limited reports of adverse events (AEs) after marketing, particularly for eptinezumab launched in 2020. The study aimed to mine and analyze the AE signals with four anti-CGRP mAbs from the United States Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) database to gain insights into the safety profile of these medications post-marketing. Methods: All AE reports on the four anti-CGRP mAbs (erenumab, galcanezumab, fremanezumab, and eptinezumab) were retrieved from the FAERS database from the first quarter (Q1) of 2018 to Q1 of 2023. Disproportionality analysis was measured by reporting odd ratio (ROR) and Bayesian confidence propagation neural network (BCPNN) to identify potential AE signals. Comparisons were made between the four drugs in terms of AEs. Results: A total of 38,515 reports of erenumab, 19,485 reports of galcanezumab, 5,332 reports of fremanezumab, and 2,460 reports of eptinezumab were obtained, mostly reported in the second to third year after launch in the market. The common AEs to erenumab included constipation (17.93%), injection site pain (14.08%), and alopecia (7.23%). The AEs that occurred more frequently with galcanezumab included injection site pain (24.37%), injection site erythema (5.35%), and injection site haemorrhage (4.97%). Common AEs related to fremanezumab were injection site pain (13.10%), injection site erythema (7.02%), and injection site pruritus (5.47%). Fatigue (13.54%), throat irritation (9.02%), and pruritus (8.20%) were the most common AEs with eptinezumab. In addition, there are new AEs that were not listed in the drug instructions but occurred concurrently with multiple drugs, such as Raynaud's phenomenon, weight increase, menstrual disorders, throat tightness, and paraesthesia oral. Conclusion: Common AE signals of the four anti-CGRP mAbs and new AE signals were found to provide a reference for clinical drug selection in clinical practice.

Degree of Alignment Between Japanese Patients and Physicians on Alopecia Areata Disease Severity and Treatment Satisfaction: A Real-World Survey

INTRODUCTION

Alopecia areata (AA) is characterized by non-scarring scalp and/or body hair loss and can negatively impact patient mental health. Data are limited on the alignment of patient and physician perceptions of AA severity with each other and with Japanese Dermatological Association (JDA) guideline criteria, and of patient-physician alignment on treatment satisfaction. Therefore, we performed analyses to compare JDA severity groupings with patient-physician alignment on disease severity and to explore treatment satisfaction in AA in Japan.

METHODS

Data were drawn from the Adelphi AA Disease Specific Programme (DSP)™, a real-world survey of physicians and patients with AA in Japan conducted January-March 2021. Patients and physicians reported patient AA severity as mild, moderate or severe based on their subjective judgement. Patients were then categorized into five hair loss severity groups according to JDA criteria (S1-5), and patient-physician pairs were matched to assess alignment on severity and treatment satisfaction.

RESULTS

Subjective patient- and physician-reported disease severity generally followed JDA severity groupings. The percentage of patient-physician alignment on severity recognition was 76.3% in the overall population. In misaligned pairs, 20.2%, 14.5%, 7.3%, 25.0% and 0.0% of physicians rated disease as more severe than patients in S1, S2, S3, S4 and S5, respectively. Regarding treatment satisfaction, patient-physician alignment was 57.6% in the overall population. In S5, 46.2% of physicians reported being less satisfied than patients. Both physicians and patients cited lack of efficacy as the main reason for dissatisfaction. Of 221 patients, 39.8% and 29.9% were categorized as borderline-abnormal cases for anxiety and depression, respectively.

CONCLUSIONS

This study highlights previously unreported patient-physician misalignment on disease severity, level of treatment dissatisfaction and unmet needs due to the lack of effective treatment. Further study on how improvement of the misalignment between physicians and patients could increase both patient and physician satisfaction with treatment and improve the quality of life for patients with AA.

Anxiety and Depression in Patients with Alopecia Areata in Eskisehir, Turkey

Background

Conflicting results have emerged in studies conducted to reveal the relationship between alopecia areata (AA) and depression and anxiety. The comorbidity of depression and anxiety in patients with patchy AA who applied to a tertiary care center will be investigated and compared with a healthy control group.

Methods

This study included 86 patients with AA and 85 healthy volunteers. The patients and controls completed Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BDI).

Results

The average BDI of the patient group was 13.45±8.59, while in the control group, it was 7.2±5.7 (p = 0.002). The average BAI of the patient group was 12.56±8.76, while in the control group, it was 6.01±5.87 (p = 0.019). Depression was detected in 30.2% (n = 26) of the patients and anxiety was detected in 19.8% (n = 17) of the patients. In the control group, the rate of depression was 5.9% (n = 5) and the rate of anxiety was 7.1% (n = 6). There was a statistically significant difference between the patients and the control group in terms of depression (p < 0.001) and anxiety (p < 0.001).

Conclusion

Depression and anxiety were more prevalent in patients with AA than in healthy volunteers. Dermatologists should keep in mind psychiatric diseases such as depression and anxiety that may accompany patients diagnosed with AA.

Overview of alopecia areata for managed care and payer stakeholders in the United States

Alopecia areata (AA) is an autoimmune disease with a complex pathophysiology resulting in nonscarring hair loss in genetically susceptible individuals. We aim to provide health care decision makers an overview of the pathophysiology of AA, its causes and diagnosis, disease burden, costs, comorbidities, and information on current and emerging treatment options to help inform payer benefit design and prior authorization decisions. Literature searches for AA were conducted using PubMed between 2016 and 2022 inclusive, using search terms covering the causes and diagnosis of AA, pathophysiology, comorbidities, disease management, costs, and impact on quality of life (QoL). AA is a polygenic autoimmune disease that significantly impacts QoL. Patients with AA face economic burden and an increased prevalence of psychiatric disease, as well as numerous systemic comorbidities. AA is predominantly treated using corticosteroids, systemic immunosuppressants, and topical immunotherapy. Currently, there are limited data to reliably inform effective treatment decisions, particularly for patients with extensive disease. However, several novel therapies that specifically target the immunopathology of AA have emerged, including Janus kinase (JAK) 1/2 inhibitors such as baricitinib and deuruxolitinib, and the JAK3/tyrosine kinase expressed in hepatocellular carcinoma (TEC) family kinase inhibitor ritlecitinib. To support disease management, a disease severity classification tool, the Alopecia Areata Severity Scale, was recently developed that evaluates patients with AA holistically (extent of hair loss and other factors). AA is an autoimmune disease often associated with comorbidities and poor QoL, which poses a significant economic burden for payers and patients. Better treatments are needed for patients, and JAK inhibitors, among other approaches, may address this tremendous unmet medical need.

The Role of Sex and Gender in Dermatology - From Pathogenesis to Clinical Implications

BACKGROUND

Sex and gender have increasingly been recognized as significant risk factors for many diseases, including dermatological conditions. Historically, sex and gender have often been grouped together as a single risk factor in the scientific literature. However, both may have a distinct impact on disease incidence, prevalence, clinical presentation, severity, therapeutic response, and associated psychological distress.

OBJECTIVES AND PROJECT DESCRIPTION

The mechanisms that underlie differences in skin diseases between males, females, men, and women remain largely unknown. The specific objectives of this review paper are:To highlight the biological differences between males and females (sex), as well as the sociocultural differences between men and women (gender) and how they impact the integumentary system.To perform a literature review to identify important sex- and gender-related epidemiological and clinical differences for various skin conditions belonging to a range of disease categories and to discuss possible biological and sociocultural factors that could explain the observed differences.To discuss dermatological skin conditions and gender-affirming treatments within the transgender community, a population of individuals who have a gender identity which is different than the gender identity they were assigned at birth.

FUTURE IMPACT

With the rising number of individuals that identify as non-binary or transgender within our increasingly diverse communities, it is imperative to recognize gender identity, gender, and sex as distinct entities. By doing so, clinicians will be able to better risk-stratify their patients and select treatments that are most aligned with their values. To our knowledge, very few studies have separated sex and gender as two distinct risk factors within the dermatology literature. Our article also has the potential to help guide future prevention strategies that are patient-tailored rather than using a universal approach.

Overall and Racial and Ethnic Subgroup Prevalences of Alopecia Areata, Alopecia Totalis, and Alopecia Universalis

Importance

Prevalences of alopecia areata (AA), alopecia totalis (AT), and alopecia universalis (AU) are poorly established.

Objective

To estimate overall and subgroup prevalences of AA and its subtypes.

Design, Setting, and Participants

This cross-sectional study using electronic records comprising the Explorys database (Watson Health, IBM Corporation) included children, adolescents, and adults seeking healthcare across the 4 census regions in the US between January 1, 2019, and December 31, 2019. The statistical analysis was conducted between July 21, 2022, and December 22, 2022.

Main Outcomes and Measures

Prevalent cases of AA, AT, and AU.

Results

Of the 1 093 176 patients who met inclusion criteria, 1812 had at least 1 code for AA, 1216 female (67%) and 596 male (33%) patients. Overall age-and-sex standardized prevalences among adults and among children and adolescents were observed to be 0.18% and 0.10%, respectively. The age-standardized prevalence ratio in women to men was 1.32. Standardized prevalence was highest in those aged 30 to 39 (297 per 100 000; 95% CI, 263-335) and 40 to 49 (270 per 100 000; 95% CI, 240-303) years. The highest standardized prevalence was observed among Asian patients (414 per 100 000; 95% CI, 306-548), followed by patients reporting another race or multiple races (314 per 100 000; 95% CI, 266-368), Black (226 per 100 000; 95% CI, 199-255), and Hispanic/Latino (212 per 100 000; 95% CI, 129-328) patients. White patients had the lowest standardized prevalence (168 per 100 000; 95% CI, 157-179) among racial and ethnic subgroups. Relative to White patients, standardized prevalence ratios for Asian, Black, and Hispanic/Latino patients were 2.47 (95% CI, 2.17-2.81), 1.35 (95% CI, 1.26-1.44), and 1.26 (95% CI, 1.03-1.55), respectively. Cases of AT and AU comprised approximately 9% of patients diagnosed with AA.

Conclusions and Relevance

The findings of this cross-sectional study suggest that there is a significant burden of AA, AT, and AU in the US in which people of color, particularly Asian Americans, appear to be disproportionately affected.

Increased Risk of Suicide Attempt in Patients with Alopecia Areata: A Nationwide Population-Based Cohort Study

BACKGROUND

There is growing evidence that patients with alopecia areata (AA) have an increased risk of developing psychiatric comorbidities. However, the relationship between AA and suicidal behaviors remains unclear.

OBJECTIVE

The objective of this study was to investigate the association between AA and suicidal behaviors.

METHODS

Participants were recruited from the National Health Insurance Research Database in Taiwan, including 10,515 patients with AA and 10,5150 matched controls, to assess the risk of suicide attempts. A Cox regression model was used for all analyses.

RESULTS

Compared with the controls, an increased risk of suicide attempts was observed in patients with AA, with an adjusted hazard ratio of 6.28 (95% confidence interval, 4.47-8.81). Suicide risk remained significantly elevated in AA patients when stratified by underlying psychiatric disorders. The mean age of initial suicidal behaviors was also lower in patients with AA.

CONCLUSIONS

Patients with AA had a significantly higher incidence of suicidal attempts than controls, regardless of concurrent psychiatric illness. Further studies are needed to elucidate the pathophysiology of the association between AA and suicidality. In addition, dermatologists should be aware of the increased suicidality of patients with AA.

The burden of alopecia areata: A scoping review focusing on quality of life, mental health and work productivity

Alopecia areata (AA) is a common inflammatory autoimmune disease of the hair which can have a significant negative impact on quality of life (QoL), mental health and productivity. The aim of this scoping review is to elucidate the burden of AA focusing on these three realms. Inclusion criteria included all original manuscripts with no restriction on study type or statistical method written in English (or having an English abstract). For QoL 40 articles were included, 85 for psychiatric comorbidities, and 9 for work/school absenteeism/presenteeism mostly consisting of cross-sectional and observational cohort studies. QoL impairment was detected in over 75% of patients and up to one-third reported extremely severe QoL impairments. Specific QoL dimensions with the greatest impact were embarrassment, social functioning, as well as shopping and/or housework. Cross-sectional studies assessing the psychological burden of adult patients with AA found that the presence of signs of anxiety and/or depression ranged from 30% to 68% and affected all age groups. Rates of work absenteeism and unemployment were significantly higher in AA patients compared to healthy controls. Up to 62% reported making major life decisions including relationships, education and career based on their AA. Additionally, the extensive camouflage techniques and time lost from work led to a strong financial burden for patients and the numerous physician visits added to the healthcare costs. The overall impact of AA stretches much further than simply being an aesthetic concern and can negatively impact every part of an individual's life. An individualized approach and effective treatments will help reduce the psychosocial consequences and distress and return patients to their normal state of health.

Exploring the overlap between alopecia areata and major depressive disorder: Epidemiological and genetic perspectives

BACKGROUND

Research suggests that Alopecia areata (AA) and Major Depressive Disorder (MDD) show substantial comorbidity. To date, no study has investigated the hypothesis that this is attributable to shared genetic aetiology.

OBJECTIVES

To investigate AA-MDD comorbidity on the epidemiological and molecular genetic levels.

METHODS

First, epidemiological analyses were performed using data from a cohort of adult German health insurance beneficiaries (n = 1.855 million) to determine the population-based prevalence of AA-MDD comorbidity. Second, analyses were performed to determine the prevalence of MDD in a clinical AA case-control sample with data on psychiatric phenotypes, stratifying for demographic factors to identify possible contributing factors to AA-MDD comorbidity. Third, the genetic overlap between AA and MDD was investigated using a polygenic risk score (PRS) approach and linkage disequilibrium score (LDSC) regression. For PRS, summary statistics from a large MDD GWAS meta-analysis (PGC-MD2) were used as the training sample, while a Central European AA cohort, including the above-mentioned AA patients, and an independent replication US-AA cohort were used as target samples. LDSC was performed using summary statistics of PGC-MD2 and the largest AA meta-analysis to date.

RESULTS

High levels of AA-MDD comorbidity were reported in the population-based (MDD in 24% of AA patients), and clinical samples (MDD in 44% of AA patients). MDD-PRS explained a modest proportion of variance in AA case-control status (R²  = 1%). This signal was limited to the major histocompatibility complex (MHC) region on chromosome 6. LDSC regression (excluding MHC) revealed no significant genetic correlation between AA and MDD.

CONCLUSIONS

As in previous research, AA patients showed an increased prevalence of MDD. The present analyses suggest that genetic overlap may be confined to the MHC region, which is implicated in immune function. More detailed investigation is required to refine understanding of how the MHC is involved in the development of AA and MDD comorbidity.

Anxiety, depression, and quality of life in children and adults with alopecia areata: A systematic review and meta-analysis

Introduction

Alopecia areata (AA) is a non-scarring hair loss condition, subclassified into AA, alopecia universalis, and alopecia totalis. There are indications that people with AA experience adverse psychosocial outcomes, but previous studies have not included a thorough meta-analysis and did not compare people with AA to people with other dermatological diagnoses. Therefore, the aim of this systematic review and meta-analysis was to update and expand previous systematic reviews, as well as describing and quantifying levels of anxiety, depression, and quality of life (QoL) in children and adults with AA.

Methods

A search was conducted, yielding 1,249 unique records of which 93 were included.

Results

Review results showed that people with AA have higher chances of being diagnosed with anxiety and/or depression and experience impaired QoL. Their psychosocial outcomes are often similar to other people with a dermatological condition. Meta-analytic results showed significantly more symptoms of anxiety and depression in adults with AA compared to healthy controls. Results also showed a moderate impact on QoL. These results further highlight that AA, despite causing little physical impairments, can have a significant amount on patients' well-being.

Discussion

Future studies should examine the influence of disease severity, disease duration, remission and relapse, and medication use to shed light on at-risk groups in need of referral to psychological care.

Epidemiological Trends in Alopecia Areata at the Global, Regional, and National Levels

Background

No comprehensive studies have been published on the global burden of alopecia areata since 2010.

Objective

We aimed to measure the global, regional, and national incidence of alopecia areata and disability-adjusted life-years (DALYs) by age, sex, and socio-demographic index (SDI) value from 1990 to 2019.

Methods

Data were extracted from the Global Burden of Disease Study 2019. Estimated annual percentage changes (EAPCs) were calculated to quantify temporal trends in the age-standardized rates of alopecia areata incidence and DALYs. The correlations between EAPCs in the age-standardized rates and SDI values were also analyzed.

Results

From 1990 to 2019, the alopecia areata incidence number and the associated number of DALYs increased globally by 49.14%, and 49.51%, respectively. The global age-standardized incidence rate decreased (EAPC, −0.13; 95% confidence interval [CI], −0.13 to −0.12) and the age-standardized DALY rate showed a downward trend (EAPC, −0.12; 95% CI, −0.13 to −0.11). The largest increases in the age-standardized incidence rate and age-standardized DALY rate were observed in Low SDI quintile and Western Sub-Saharan Africa regions. The regions with the greatest changes in the incidence of alopecia areata were Central Sub-Saharan Africa and Western Sub-Saharan Africa. The three countries with the largest increases in alopecia areata incidence from 1990 to 2019 were Kuwait (EAPC, 0.15), South Sudan (EAPC, 0.12), and Nigeria (EAPC, 0.11). The age-standardized incidence rate was higher in females than in males.

Conclusion

Globally, both the age-standardized incidence rate and age-standardized DALY rate of alopecia areata showed decreasing trends. Future preventive strategies should focus on low-income countries, Central Sub-Saharan Africa, Western Sub-Saharan Africa, Kuwait, South Sudan, Nigeria.

Translational impact of omics studies in alopecia areata: recent advances and future perspectives

INTRODUCTION

Alopecia areata (AA) is a non-scarring, hair loss disorder and a common autoimmune-mediated disease with an estimated lifetime risk of about 2%. To date, the treatment of AA is mainly based on suppression or stimulation of the immune response. Genomics and transcriptomics studies generated important insights into the underlying pathophysiology, enabled discovery of molecular disease signatures, which were used in some of the recent clinical trials to monitor drug response and substantiated the consideration of new therapeutic modalities for the treatment of AA such as abatacept, dupilumab, ustekinumab and Janus Kinase (JAK) inhibitors.

AREAS COVERED

In this review, genomics and transcriptomics studies in AA are discussed in detail with particular emphasis on their past and prospective translational impacts. Microbiome studies are also briefly introduced.

EXPERT OPINION

The generation of large datasets using the new high-throughput technologies has revolutionized medical research and AA has also benefited from the wave of omics studies. However, the limitations associated with JAK inhibitors and clinical heterogeneity in AA patients underscore the necessity for continuing omics research in AA for discovery of novel therapeutic modalities and development of clinical tools for precision medicine.

Health-related quality of life in patients with alopecia areata: Results of a Japanese survey with norm-based comparisons

Alopecia areata (AA) is a non-scarring hair loss disorder affecting approximately 2% of the global population. AA is reported to have a significant negative impact on the emotional and psychological well-being of the patients. This study aimed to evaluate the health-related quality of life (HRQoL) of Japanese patients with AA in comparison to the Japanese population norms (national standard values for Japanese) using Short Form Health Survey 36 Item Version 2.0 (SF-36v2). The study also aimed to access the negative effect of AA on patients' daily lives and the proportion of patients having anxiety and/or depression. This cross-sectional, non-interventional web-based survey study included 400 participants aged 17-84 years currently suffering from medically diagnosed AA. The assessment tools integrated in the online questionnaire included SF-36v2, the Dermatology Life Quality Index (DLQI), and the Hospital Anxiety and Depression Scale (HADS). All outcome measures from the tools were evaluated across the study population. SF-36v2 subscale scores for patients with AA revealed lower scores specifically for mental health (45.7 ± 10.1 points), social functioning (45.8 ± 10.9 points), vitality (46.2 ± 9.8 points), and role emotional (46.9 ± 11.6 points) as compared to the Japanese population norms of 50 ± 10 points each. The DLQI questionnaire-based analysis indicated that 32.1% of respondents showed a moderate to extremely large effect on their lives; and HADS-A (anxiety) and HADS-D (depression) scores categorized 46.0% and 41.8% respondents as doubtful-to-definite cases, respectively. Multivariate linear regression revealed that hair loss range, age, comorbidities, and depression significantly worsened DLQI scores. In conclusion, the results of this survey demonstrated that a significant decrease in the HRQoL scores was observed in Japanese patients with AA in comparison with the national norms. Hence, emphasis on mental health is crucial for AA management.

An Acceptance and Commitment Therapy Prototype Mobile Program for Individuals With a Visible Difference: Mixed Methods Feasibility Study

Background

Mobile apps may offer a valuable platform for delivering evidence-based psychological interventions for individuals with atypical appearances, or visible differences, who experience psychosocial appearance concerns such as appearance-based social anxiety and body dissatisfaction. Before this study, researchers and stakeholders collaboratively designed an app prototype based on acceptance and commitment therapy (ACT), an evidence-based form of cognitive behavioral therapy that uses strategies such as mindfulness, clarification of personal values, and value-based goal setting. The intervention also included social skills training, an established approach for increasing individuals’ confidence in managing social interactions, which evoke appearance-based anxiety for many.

Objective

In this study, the authors aim to evaluate the feasibility of an ACT-based app prototype via the primary objectives of user engagement and acceptability and the secondary feasibility objective of clinical safety and preliminary effectiveness.

Methods

To address the feasibility objectives, the authors used a single-group intervention design with mixed methods in a group of 36 participants who have a range of visible differences. The authors collected quantitative data via measures of program use, satisfaction ratings, and changes over 3 time points spanning 12 weeks in outcomes, including selected ACT process measures (experiential avoidance, cognitive defusion, and valued action), scales of appearance concerns (appearance-based life disengagement, appearance-fixing behaviors, appearance self-evaluation, and fear of negative appearance evaluation), and clinical well-being (depression and anxiety). Semistructured exit interviews with a subsample of 12 participants provided qualitative data to give a more in-depth understanding of participants’ views and experiences of the program.

Results

In terms of user engagement, adherence rates over 6 sessions aligned with the upper boundary of those reported across mobile mental health apps, with over one-third of participants completing all sessions over 12 weeks, during which a steady decline in adherence was observed. Time spent on sessions matched design intentions, and engagement frequencies highlighted semiregular mindfulness practice, mixed use of value-based goal setting, and high engagement with social skills training. The findings indicate a good overall level of program acceptability via satisfaction ratings, and qualitative interview findings offer positive feedback as well as valuable directions for revisions. Overall, testing for clinical safety and potential effectiveness showed encouraging changes over time, including favorable changes in appearance-related life disengagement, appearance-fixing behaviors, and selected ACT measures. No iatrogenic effects were indicated for depression or anxiety.

Conclusions

An ACT-based mobile program for individuals struggling with visible differences shows promising proof of concept in addressing appearance concerns, although further revisions and development are required before further development and more rigorous evaluation.

Low Level Laser versus Platelet-rich Plasma in Treatment of Alopecia Areata: A Randomized Controlled Intra-patient Comparative Study

Abstract                                                                                                           Background: Non-scarring alopecia areata (AA) is a disease that is mediated through autoimmunity. Recently, autologous platelet-rich plasma (PRP) and photobiomodulation (PBM), commonly known as low-level laser (or light, LLLT) have been suggested to provide a valuable role in stimulating the growth of hair follicles (HF) Aim: Compare between the significance and wellbeing of PRP and LLLT in the management of AA. Patients & methodology: Thirty patients, each having three patches of AA participated in the study. Patches were assigned randomly to have one of the two treatments: PRP or LLLT. The third patch served as a control and received placebo treatment. PRP was done once weekly whereas LLLT was done 3 sessions per week for a maximum of 6 weeks. Patients were followed up at one month and three months. The thickness and density of hair were evaluated by the folliscope. Results: A noteworthy higher improvement was detected in the thickness and the density of hair in the PRP treated patches as evaluated by the folliscope and patients satisfaction. The obtained outcomes were sustained during the 12 week follow-up period in most of patients. Conclusion: PRP and LLLT could be considered as efficacious alternatives for the treatments of  AA with the least morbidity in addition to a little cost profit ratio. KEYWORDS: Alopecia areata, platelet-rich plasma, folliscope, photobiomodulation, low level laser therapy.  

Alopecia areata: Current understanding of the pathophysiology and update on therapeutic approaches, featuring the Japanese Dermatological Association guidelines

Alopecia areata (AA) is a relatively common nonscarring hairloss disease characterized by an autoimmune response to anagen hair follicles (HFs). Accumulated evidence suggests that collapse of the HF immune privilege subsequent to triggering events, represented by viral infection, leads to autoimmune response in which autoreactive cytotoxic CD8+NKG2D+ T cells mainly target exposed HF autoantigens. AA had been recognized as type 1 inflammatory disease, but recent investigations have suggested some roles of type 2- and Th17-associated mediators in AA pathogenesis. The significance of psychological stress in AA pathogenesis is less emphasized nowadays, but psychological comorbidities, such as depression and anxiety, attract greater interest in AA management. In this regard, the disease severity may not solely be evaluated by the extent of hair loss. Use of trichoscopy markedly improved the resolution of the diagnosis and evaluation of the phase of AA, which is indispensable for the optimization of treatment. For the standardization of AA management, the establishment of guidelines/expert consensus is pivotal. Indeed, the Japanese Dermatological Association (JDA) and other societies and expert groups have published guidelines/expert consensus reports, which mostly recommend intralesional/topical corticosteroid administration and contact immunotherapy as first-line treatments, depending on the age, disease severity, and activity of AA. The uniqueness of the JDA guidelines can be found in their descriptions of intravenous corticosteroid pulse therapy, antihistamines, and other miscellaneous domestically conducted treatments. Considering the relatively high incidence of spontaneous regression in mild AA and its intractability in severe subsets, the importance of course observation is also noted. Evidenced-based medicine for AA is currently limited, however, novel therapeutic approaches, represented by JAK inhibitors, are on their way for clinical application. In this review, the latest understanding of the etiopathogenesis and pathophysiology, and update on therapeutic approaches with future perspectives are summarized for AA, following the current version of the JDA AA management guidelines.
