Comorbidity of psychiatric disorders in children and adolescents with alopecia areata in a child and adolescent psychiatry clinical sample

Comorbid Conditions Associated with Alopecia Areata: A Systematic Review and Meta-analysis

BACKGROUND

Alopecia areata (AA) is a complex autoimmune condition resulting in nonscarring hair loss. In recent years, many studies have provided new evidence on comorbid diseases present in patients with AA. However, some studies have conflicting results, and analyses conducting a comprehensive approach are lacking.

OBJECTIVE

The aim of our study was to provide an updated systematic review and meta-analysis of medical comorbidities associated with AA.

METHODS

We searched PubMed, Embase, and Web of Science for case-control, cross-sectional, and cohort studies investigating medical comorbidities in AA published from inception through 1 February 2023.

RESULTS

We screened 3428 abstracts and titles and reviewed 345 full text articles for eligibility. Ultimately, 102 studies were analyzed, comprising 680,823 patients with AA and 72,011,041 healthy controls. Almost all included studies (100 of 102 studies) were of satisfactory to high quality (Newcastle-Ottawa scale score ≥ 4). Among patients with AA, comorbidities with the highest odds ratios (OR) compared with healthy controls and data available from more than one study included vitamin D deficiency (OR 10.13, 95% CI 4.24-24.20), systemic lupus erythematous (OR 5.53, 95% CI 3.31-9.23), vitiligo (OR 5.30, 95% CI 1.86-15.10), metabolic syndrome (OR 5.03, 95% CI 4.18-6.06), and Hashimoto's thyroiditis (OR 4.31, 95% CI 2.51-7.40). AA may be a protective factor for certain disorders, for which the AA group had lower odds compared with healthy controls, such as irritable bowel syndrome (OR 0.38, 95% CI 0.14-0.99) and colorectal cancer (OR 0.61, 95% CI 0.42-0.89).

CONCLUSION

These findings corroborate and contextualize the risks across comorbidities for patients with AA. Further work should be done to identify the underlying pathophysiology and understand appropriate screening criteria.

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.

Real-World Treatment Patterns among Patients with Alopecia Areata in the USA: A Retrospective Claims Analysis

Alopecia areata is an autoimmune disorder characterized by hair loss, for which there are few treatment options. This claims-based study characterized recent real-world treatment patterns among patients in the USA with alopecia areata, including the subtypes alopecia totalis and alopecia universalis, in the first year after diagnosis of an episode of alopecia areata. Approximately 5% of all patients (adults (age ≥ 18 years), n = 7,703; adolescents (age 12-17 years), n = 595) had alopecia totalis or alopecia universalis. Corticosteroids were the most common first-line (1L) and second-line (2L) treatments. The mean time from diagnosis of alopecia areata to initiation of 1L treatment was 2.2 days for adults and 2.6 days for adolescents; mean 1L duration was 76.9 and 64.3 days, respectively. For adults (57.5%) and adolescents (59.7%) with 2L therapy, the mean time from 1L discontinuation to 2L initiation was 57.2 and 53.6 days, respectively; the mean duration of 2L treatment was 55.5 and 50.1 days, respectively. More patients with vs without alopecia totalis or alopecia universalis initiated 2L therapy (adults: 71.9% vs 56.8%; adolescents: 71.4% vs 58.9%). The proportion of days covered during the first year post-diagnosis was 36.7% (adults) and 34.1% (adolescents). These results highlight the substantial disease burden of alopecia areata and a need for more effective treatments.

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.

Healthcare Utilization and Costs Among US Adolescents With Alopecia Areata

Background: Alopecia areata (AA) is an autoimmune disease of hair loss affecting people of all ages. Alopecia totalis (AT) and universalis (AU) involve scalp and total body hair loss, respectively. AA significantly affects quality of life, but evidence on the economic burden in adolescents is limited. Objectives: To assess healthcare resource utilization (HCRU) and all-cause direct healthcare costs, including out-of-pocket (OOP) costs, of US adolescents with AA. Methods: IBM MarketScan® Commercial and Medicare databases were used to identify patients aged 12-17 years with ≥2 claims with AA/AT/AU diagnosis (prevalent cases), from October 1, 2015, to March 31, 2018, enrolled for ≥12 months before and after the first AA diagnosis (index). Patients were matched 1:3 to non-AA controls on index year, demographics, plan type, and Charlson Comorbidity Index. Per patient per year HCRU and costs were compared post-index. Results: Patients comprised 130 AT/AU adolescents and 1105 non-AT/AU adolescents (53.8% female; mean age, 14.6 years). Post-index, AT/AU vs controls had more outpatient (14.5 vs 7.1) and dermatologist (3.6 vs 0.3) visits, higher mean plan costs ($9397 vs $2267), including medical ($7480 vs $1780) and pharmacy ($1918 vs $487) costs, and higher OOP costs ($2081 vs $751) (all P<.001). The non-AT/AU cohort vs controls had more outpatient (11.6 vs 8.0) and dermatologist (3.4 vs 0.4) visits, higher mean plan costs ($7587 vs $4496), and higher OOP costs ($1579 vs $805) (all P<.001). Discussion: This large-sample, real-world analysis found that adolescents with prevalent AA had significantly higher HCRU and all-cause costs than matched controls. The greater burden was driven by more frequent outpatient visits, and higher payer medical and pharmacy costs in comparison with controls. Oral corticosteroid use was higher among patients with AT/AU; topical and injectable corticosteroid use was higher for non-AT/AU. Although the data preclude the identification of AA-attributable costs, the matched-control design allows an estimation of incremental all-cause costs associated with AA. Conclusions: Adolescents with AA incurred substantial incremental healthcare costs, with greater costs incurred among those with AT/AU. Study findings suggest that AA incurs costs as a medical condition with a high burden on adolescent patients and health plans.

An integrated scalp and blood biomarker approach suggests the systemic nature of alopecia areata

BACKGROUND

Alopecia areata (AA) is characterized by immune dysregulation in both scalp and blood, but a large-scale approach establishing biomarkers of AA incorporating both scalp tissue and serum compartments is lacking. We aimed to characterize the transcriptomic signature of AA lesional and nonlesional scalp compared to healthy scalp and determine its relationship with the blood proteome in the same individuals, with comparative correlations to clinical AA disease severity.

METHODS

We evaluated lesional and nonlesional scalp tissues and serum from patients with moderate-to-severe AA (n = 18) and healthy individuals (n = 8). We assessed 33,118 genes in AA scalp tissue using RNAseq transcriptomic evaluation and 340 inflammatory proteins in serum using OLINK high-throughput proteomics. Univariate and multivariate approaches were used to correlate disease biomarkers with Severity of Alopecia Tool (SALT).

RESULTS

A total of 608 inflammatory genes were differentially expressed in lesional AA scalp (fold change/FCH>1.5, false discovery rate/FDR<0.05) including Th1 (IFNG/IL12B/CXCL11), Th2 (IL13/CCL18), and T-cell activation-related (ICOS) products. Th1/Th2-related markers were significantly correlated with AA clinical severity in lesional/nonlesional tissue, while keratins (KRT35/KRT83/KRT81) were significantly downregulated in lesional compared to healthy scalp (p < .05). Expression of cardiovascular/atherosclerosis-related markers (MMP9/CCL2/IL1RL1/IL33R/ST2/AGER) in lesional scalp correlated with their corresponding serum expression (p < .05). AA scalp demonstrated significantly greater biomarker dysregulation compared to blood. An integrated multivariate approach combining scalp and serum biomarkers improved correlations with disease severity/SALT.

CONCLUSION

This study contributes a unique understanding of the phenotype of moderate-to-severe AA with an integrated scalp and serum biomarker model suggesting the systemic nature of the disease, advocating for the need for immune-based systemic treatment.

The spectrum of pediatric scarring alopecia: A retrospective review of 27 patients seen at Mayo Clinic

BACKGROUND/OBJECTIVE

There are few studies examining pediatric scarring alopecia. The objective of this study is to characterize the clinicopathologic findings, comorbidities, and treatment outcomes of pediatric patients with scarring alopecia.

METHODS

Retrospective review of patients under age 18 diagnosed with scarring alopecia at Mayo Clinic from 01/01/1992 through 02/05/2019.

RESULTS

27 patients met inclusion criteria with a mean age of 11.2 years and a racial breakdown of 85.2% (23) White, 11.1% (3) Black, and 3.7% (1) Multiracial. Clinical scarring was noted in most (23, 85.2%). Biopsy confirmed the diagnosis in most (24, 88.9%). The most common diagnoses were folliculitis decalvans (6, 22.2%), lichen planopilaris (6, 22.2%), aplasia cutis congenita (4, 14.8%), tinea capitis (4, 14.8%), and morphea (3, 11.1%). Comorbid depression (6, 22.2%) and anxiety (6, 22.2%) were prevalent. Of the patients who received follow-up, most who pursued treatment achieved stabilization (55.5%) or slowing of progression (27.8%), with 44.4% of those treated experiencing regrowth. Mean time to stabilization in the treated population was 19.6 months. Two patients did not pursue treatment, but received follow-up and these untreated patients did not experience hair regrowth.

CONCLUSIONS

Most patients presented with clinically evident primary scarring alopecia. Biopsy may confirm the diagnosis. Active treatment should be pursued, and successful treatment often requires combination therapies. Time to stabilization often takes years. Screening for depression and anxiety should be pursued.

Psychiatric basics of alopecia areata in pediatric patients: Evaluation of emotion dysregulation, somatization, depression, and anxiety levels

BACKGROUND/OBJECTIVE

Alopecia areata (AA) is a skin disease characterized by sudden-onset hair loss. The relationship between psychiatric status and AA has not been fully elucidated. The aim of this study was to evaluate emotion dysregulation, somatization, depression, and anxiety levels in children and adolescents with AA.

METHODS

The study included 27 patients aged 8-18 years diagnosed with AA, and an age and gender-matched control group consisting of 30 cases without a known chronic medical disease. All individuals were screened for existing psychiatric illnesses by a pediatric psychiatrist through the Schedule for Affective Disorders and Schizophrenia for School-Age Children Present and Lifetime Version (K-SADS-PL). The patients were then evaluated using the Children's Depression Inventory (CDI), Screen for Child Anxiety-Related Emotional Disorders (SCARED), State-Trait Anxiety Inventory for Children (STAI-C), and Children Somatization Inventory (CSI-24). In addition, the patients' parents were asked to complete the Emotion Regulation Checklist-Family Form (ERC).

RESULTS

When comparing the scale scores of the AA and control group, there was a statistically significant difference between the groups in terms of the Emotional Lability/Negativity subscale scores on ERC. K-SADSPL ratios denoted features of at least one psychiatric condition in 62.9% and 16.6% of the AA group and control group, respectively.

CONCLUSIONS

Our results emphasize the importance of psychiatric evaluation in patients with AA. Our study also reveals the need for further studies with a larger sample of AA patients being evaluated in terms of emotion regulation.

Anxiety and depression in pediatric patients with vitiligo and alopecia areata and their parents: A cross-sectional controlled study

BACKGROUND

Alopecia areata (AA) and vitiligo are associated with various psychiatric comorbidities, and the care of a child with AA or vitiligo may be associated with higher anxiety and depression than healthy children.

AIMS

We aimed to identify psychiatric findings in children and adolescent groups with AA and vitiligo and to evaluate the levels of anxiety and depression in their parents.

METHODS

This study included 31 patients with AA and 29 patients with vitiligo, aged seven to 17 years, and their parents. Age- and gender-matched 30 controls and their parents were included. The patients and controls completed the Revised Child Anxiety and Depression Scales-Child version (RCADS-C), and their parents completed the parent version (RCADS-P). The parents also completed the Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI). In addition, the stressful event history of all cases was noted.

RESULTS

Stressful event history was higher in the vitiligo group compared to the AA group, and it was higher in the AA and vitiligo groups compared to the control group. Separation anxiety, generalized anxiety, social phobia, and major depressive disorder (MDD) scores were higher in the AA group than controls according to the RCADS-C. According to the RCADS-P, panic disorder (PD), MDD, and total anxiety scores were higher in the AA group. Only the PD and MDD scores were higher in the vitiligo group than those of the controls based on the RCADS-P. Lastly, no significant difference was observed between the three groups concerning the parents' BAI and BDI scores.

CONCLUSIONS

Stressful events were more common in pediatric patients with vitiligo than those with AA. Anxiety symptoms were more prevalent in patients with AA than those with vitiligo.

Psychosocial and psychiatric comorbidities and health-related quality of life in alopecia areata: A systematic review

BACKGROUND

Alopecia areata (AA) is an immune-mediated disease resulting in nonscarring hair loss. Systematic reviews on the psychosocial and psychiatric comorbidities, health-related quality of life, and interventions targeting psychosocial well-being are limited.

OBJECTIVE

To conduct a systematic review of the psychosocial comorbidities, health-related quality of life, and treatment options targeting psychosocial well-being in adult and pediatric AA patients.

METHODS

A systematic review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines within the PubMed database. Specific search terms included, but were not limited to, alopecia areata, psychosocial, psychiatry, and quality of life. Studies were then evaluated for their design and categorized into corresponding levels of evidence according to the guidelines adapted from the Oxford Center for Evidence Based Medicine.

FINDINGS

Seventy-three reports met inclusion criteria, involving approximately 414,319 unique participants. AA patients were found to have psychiatric comorbidities, particularly anxiety and depression. Health-related quality of life is reduced in AA patients, but data on pediatric AA quality of life are limited. Psychotherapy is often recommended as adjuvant treatment.

CONCLUSION

AA has substantial psychosocial impact on patients and results in reduced health-related quality of life. Addressing this should be an active part of treatment.

Cross-sectional study of blood biomarkers of patients with moderate to severe alopecia areata reveals systemic immune and cardiovascular biomarker dysregulation

BACKGROUND

Although there is increased understanding of the alopecia areata (AA) pathogenesis based on studies in scalp tissues, little is known about its systemic profile.

OBJECTIVE

To evaluate the blood proteomic signature of AA and determine biomarkers associated with increased disease severity.

METHODS

In a cross-sectional study, we assessed 350 inflammatory and cardiovascular proteins using OLINK high-throughput proteomics in patients with moderate to severe AA (n = 35), as compared with healthy individuals (n = 36), patients with moderate to severe psoriasis (n = 19), and those with atopic dermatitis (n = 49).

RESULTS

Seventy-four proteins were significantly differentially expressed between AA and control individuals (false discovery rate, <.05) including innate immunity (interleukin [IL] 6/IL-8), T helper (Th) type 1 (interferon [IFN] γ/CXCL9/CXCL10/CXCL11), Th2 (CCL13/CCL17/CCL7), Th17 (CCL20/PI3/S100A12), and cardiovascular-risk proteins (OLR1/OSM/MPO/PRTN3). Eighty-six biomarkers correlated with AA clinical severity (P < .05), including Th1/Th2, and cardiovascular/atherosclerosis-related proteins, including SELP/PGLYRP1/MPO/IL-18/OSM (P < .05). Patients with AA totalis/universalis showed the highest systemic inflammatory tone, including cardiovascular risk biomarkers, compared to control individuals and even to patients with atopic dermatitis and those with psoriasis. The AA profile showed some Th1/Th2 differences in the setting of concomitant atopy.

LIMITATIONS

Our analysis was limited to 350 proteins.

CONCLUSION

This study defined the abnormalities of moderate to severe AA and associated circulatory biomarkers. It shows that AA has systemic immune, cardiovascular, and atherosclerosis biomarker dysregulation, suggesting the need for systemic treatment approaches.

Alopecia Areata: Factors That Impact Children and Adolescents

Research suggests that several factors affect children and adolescents with alopecia areata (AA). While hair loss is mostly associated with individuals undergoing chemotherapy, AA also causes individuals to lose the hair on their scalp and elsewhere on the body. This loss can be particularly devastating to children and adolescents, and can affect them socially, as well as psychologically. A mixed method research design was used to combine survey data with interview transcripts and field notes to capture a more detailed picture of AA and its effect on children and adolescents. The data reported here were extracted from a larger study utilizing nine demographic items, four independent variable items (gender, age, duration of diagnosis, age of onset), and 27 dependent variable items regarding impact factors. Subsequently, six follow-up interview questions were used with a small group for additional context. An exploratory factor analysis revealed five impact factors: Confidence/Self-Esteem, Psychological Effects, Appearance/Acceptance, Socialization, and Communication. Female participants reported significantly greater difficulty adjusting and managing AA than did their male counterparts. While most participants revealed a positive attitude about themselves, the majority were affected psychologically by this condition. Open communication with family and friends gave comfort and support to the vast majority.

Interactions between Posttraumatic Stress Disorder and Alopecia Areata in Child with Trauma Exposure: Two Case Reports

Alopecia areata (AA) is a dermatologic disease that can be seen in all age groups with nonscarring hair loss. While the causes of AA are suggested to be the role of genetic, psychological stresses, cellular and humoral immunity, and endocrine and neural factors, the underlying cause is not fully known. Psychiatric diseases are frequently reported in many studies in patients with AA. In this report, children with AA and psychiatric evaluation of them and the prominence of psychiatric evaluation in AA were discussed; AA and posttraumatic stress disorder were reviewed in the light of the relevant literature.

Health-related quality of life (HRQoL) among patients with alopecia areata (AA): A systematic review

Alopecia areata (AA) is a common skin disease that is frequently emotionally devastating. Several studies have examined the effect of AA on health-related quality of life (HRQoL). We performed a systematic review of all published studies of HRQoL in patients with AA. Eleven studies met inclusion criteria, incorporating data from 1986 patients. Patients with AA consistently demonstrate poor HRQoL scores, with greater extent of scalp involvement associated with lower HRQoL. HRQoL experienced by patients with AA is similar to that seen in patients with other chronic skin diseases including atopic dermatitis and psoriasis.

Psychiatric morbidity and quality of life in skin diseases: A comparison of alopecia areata and psoriasis

BACKGROUND

Alopecia areata (AA) and psoriasis are associated with various psychiatric comorbidities. Both greatly affect the quality of life (QOL) of patients and psychiatric comorbidities can further worsen it. Thus there is need to recognise psychiatric comorbidities and treat them in these patients.

AIMS

To determine the psychiatric morbidity and the QOL in these patients to study the factors affecting them.

METHODOLOGY

50 patients each of psoriasis and AA were included. 50 people accompanying these patients served as control group. They were diagnosed for psychiatric disorders by clinical interview. Scales used were severity of alopecia tool for AA, psoriasis area and severity index for psoriasis, WHO-QOL scale, Hamilton Rating Scale for anxiety and depression.

RESULTS

22% and 38% patients in AA and psoriasis group respectively suffered from psychiatric disorder, depression was present in 18% and 24% of patients and 4% and 12% had anxiety disorders in respective groups. The control group had only 6% of psychiatric comorbidities. QOL scores had negative correlation with Hamilton-A, Hamilton-D and severity of psoriasis scores and they were statistically significant but not with severity of AA.

CONCLUSION

Thus AA and psoriasis patients had more prevalence of psychiatric comorbidities and it had bearing on their QOL.

Reliability and validity assessment of the revised Symptom Checklist 90 for alopecia areata patients in China

No study has tested the reliability and validity of the revised Symptom Checklist 90 (SCL-90-R) for patients with alopecia areata (AA), and few have used it to evaluate the mental health of AA patients. To assess the psychological status in Chinese AA patients using the SCL-90-R, and to evaluate its reliability and validity, the psychological status of 168 patients and 100 controls was evaluated with the Chinese-version SCL-90-R. From this study, we found that The Global Severity Index and nine subscale scores on the SCL-90-R were significantly higher in AA patients than that in the controls. Moreover, The Global Severity Index and nine subscale scores on the SCL-90-R were associated with disease duration, age of onset, sex and type of AA. In addition, the SCL-90-R presented good internal consistency (whole scale α = 0.98 and split-half coefficient = 0.95). The intercorrelations between the nine subscales and their correlations with the total scale were 0.58-0.93. Factor analysis produced 22 factors with eigenvalues more than 1.0; the first factor explained 33.88% of the variance. Only hostility and paranoid ideation merged into one factor. Taken together, our data indicated that Chinese AA patients demonstrate greater psychopathology than healthy controls. The SCL-90-R can be used to assess global psychological distress in AA patients with good reliability and validity.

Serum cytokine levels and anxiety and depression rates in patients with alopecia areata

OBJECTIVE

Alopecia areata (AA) is a disease characterized by patchy hair loss. Although the etiopathogenesis of AA is still unclear, it has been hypothesized that immune system dysfunction and stress are involved. The aim of this study was to evaluate possible associations between AA and depression, anxiety and serum levels of cytokines interleukin (IL)-1β, IL-6, IL-8 and IL-10.

MATERIALS AND METHODS

Forty-three patients who were diagnosed with AA were prospectively enrolled into the study. Thirty age- and sex-matched healthy individuals were included as the control group. The Hamilton Rating Scale for Depression and the Hamilton Rating Scale for Anxiety were used. For children between the ages of 7 and 16, the Children's Depression Inventories was completed. Serum levels of the cytokines IL-1 β, IL-6, IL-8, and IL-10 were analyzed by ELISA.

RESULTS

No significant differences were observed between patients and controls with respect to serum cytokine levels (p>0.05). Depression rates were found to be 50% and 30% in AA patients and controls, respectively (p<0.05). Similarly, anxiety rates were found to be 63% and 23.3% in AA patients and controls, respectively (p<0.05).

CONCLUSION

Depression and anxiety were found more frequent in AA patients than healthy individuals. Therefore, when considering management therapy, an entire psychiatric evaluation should also be performed. However, no differences were found in serum cytokine levels of patients and controls.

A review of psychiatric disorders comorbidities in patients with alopecia areata

This is a review of psychiatric problems in patients with alopecia areata (AA). The electronic database of MedLine/PubMed was searched using the determined keywords. The rate of depression in children and adolescents with AA is up to 50%. Stressful life events are associated with AA. A rate of 39% for generalized anxiety disorders was reported. AA is highly associated with obsessive compulsive disorder (35.7%) in children and adolescents. Schizophrenia tended to be less seen in AA patients.

Psychiatric symptomatology and health-related quality of life in children and adolescents with alopecia areata

BACKGROUND

There is a very limited amount of data available regarding the relationship between alopecia areata (AA) and psychiatric morbidity and quality of life (QoL) in children and adolescents.

OBJECTIVES

The aim of this study was to determine the psychiatric state and health-related quality of life (HRQL) of children and adolescents with AA, as well as their relationships with clinical parameters.

METHODS

The sample consisted of 74 children with AA aged 8-18 years. Questionnaires were used to evaluate the psychiatric status and HRQL of the patients. The study and control groups were divided into child and adolescent groups to exclude the effect of puberty on psychological condition.

RESULTS

In the child group, patients had higher state anxiety and trait anxiety scores; they also had lower parent-rated psychosocial and total area HRQL scores than the controls did. In addition, the depression score was prone to show a positive relationship with having AA in the children. In the adolescent group, however, only the state anxiety score had a significant association with AA. All of the parent-rated HRQL scores were also prone to being lower compared with controls in this age group. Regarding determinants of HRQL, prolonged disease duration and later disease onset had positive effects, whereas severity of scalp involvement, trait anxiety and depression had negative effects, for the sample as a whole.

CONCLUSIONS

Alopecia areata is associated with poor psychiatric status and QoL, especially in childhood. The impact of the disease on QoL occurs through both clinical and psychiatric parameters.

Examining the relationship between alopecia areata, androgenetic alopecia, and emotional intelligence

BACKGROUND

Emotional stress has been associated with the development of alopecia areata (AA) and androgenetic alopecia (AGA). Emotional intelligence (EI), a component of general intelligence, is thought to govern the recognition, expression, and control of stress and other emotions. People with low EI are unable to adequately control stress in everyday life.

OBJECTIVE

To investigate EI differences between AA and AGA patients and a control population.

METHODS

Thirty-five AGA patients and 42 AA patients, with patchy (n  =  28), ophiasis (n  =  5), totalis (n  =  5), and universalis (n  =  4) distribution of hair loss, completed a 133-item Emotional Quotient-Inventory (EQ-I ) psychometric assessment. Scores were compared between AA, AGA, and 77 control subjects obtained from the North American normative population sample on which the psychometric instrument was normed.

RESULTS

Statistically significant differences were found in EI between AA patients and controls with the EQ-I Stress Tolerance scale (p  =  .005). AGA patients also differed significantly from the controls but to a lesser degree compared toAA patients. In overall EI, there were no apparent differences between AGA and AA patients.

CONCLUSIONS

AA and AGA patients exhibit a mild depressive reaction to their condition, with AA patients demonstrating a significantly stronger deficiency in coping with stress than AGA patients. The data support a psychosomatic contribution to AA. Referral of patients for EI assessment and psychosocial counseling could help reduce stress.

Current treatment strategies in pediatric alopecia areata

Alopecia areata (AA) is a non-scarring autoimmune disease of the hair follicle that can present at any age. Pediatric cases are commonly seen in a dermatology clinic, and management can potentially be challenging, with a small proportion of cases experiencing a chronic relapsing course marked by distressing hair loss that can bring about significant psychosocial morbidity. We review the established treatments for pediatric alopecia areata, alongside second and third line therapies that have shown to be efficacious. We also offer a treatment algorithm as a guide to the treatment of pediatric AA.

The -2T/C polymorphism in the adrenocorticotropin receptor gene affects stress perception of patients with alopecia areata

BACKGROUND

Altered hypothalamic-pituitary-adrenal (HPA) axis response involved in the pathogenesis of stress-associated alopecia areata (AA) has been reported. A novel polymorphism -2T>C of the adrenocorticotropin receptor (ACTHR) can result in an insufficient HPA response to stress; therefore, the functional polymorphism may underlie a role in stress-associated AA.

OBJECTIVE

To investigate the relationship between psychosocial factors and the risk of developing AA and to detect the association between the -2T>C polymorphism of ACTHR and AA.

METHODS

Stressful situations were evaluated using Holmes and Rahe's social readjustment rating scale. The ACTHR -2T>C polymorphism was examined in 263 patients with AA and 241 controls.

RESULTS

Significant elevation of psychological stress experienced by some patients with AA compared with controls (Z = 6.628, P < 0.01). The frequency of the ACTHR C allele showed a significant difference between patients with AA and controls (P = 0.004). Allele C is the risk allele with a dominant model as the -2C allele occurred more often in patients with AA (P = 0.001). There were significant differences between patients with AA with a severe stress attack versus patients with AA with no obvious stress (P < 0.001), whereas the genotype frequencies were not correlated with the type, duration of disease, and age at onset. Notably, the C allele carrier was significantly associated with stress risk in both AA and controls (P = 0.002, OR = 1.576, 95% CI: 1.148-2.162; P = 0.042, OR = 1.529, 95% CI: 1.022-2.288).

CONCLUSIONS

These findings suggest AA in some patients may be associated with stress. The ACTHR gene -2T>C variant may be one important factor that influences stress perception of patients with AA.

Concomitant presentation of alopecia areata in siblings: a rare occurrence

Alopecia areata (AA) is one among the many causes of non-scarring alopecia in children. Family history has been noted in 10-20% of cases, but concomitant presentation in siblings is extremely rare. The patterns and associations of childhood AA are similar to adults; however, there are some differences which are being highlighted in this article.

Psychiatric comorbidities in patients with alopecia areata in Taiwan: a case-control study

BACKGROUND

Alopecia areata (AA) may be related to stress and has been reported to be associated with psychiatric disorders. Nevertheless, a nationwide study of the relationship between AA and comorbid psychiatric diseases has not been conducted, and the effect of onset age has rarely been reported.

OBJECTIVES

To analyse the associations between AA and various psychiatric disorders using a nationwide database in Taiwan.

METHODS

Data were obtained from the National Health Insurance Research Database of Taiwan from 2000 to 2009. In total, 5117 patients with AA and 20 468 age- and gender-matched controls were enrolled.

RESULTS

Patients with AA tended to have more coexisting anxiety and less comorbid schizophrenia. Differences in ages of onset revealed differences in comorbidities. An increased risk of depression [odds ratio (OR) 2·23; 95% confidence interval (CI) 1·09-4·54] was found in patients with AA aged < 20years. An increased rate of anxiety (OR 1·43; CI 1·15-1·77) was observed with AA onset between the ages of 20 and 39years. The highest odds of obsessive-compulsive disorder (OR 3·00; CI 1·11-8·12) and anxiety (OR 2·05; CI 1·56-2·68) were observed in patients with AA aged 40-59years. Moreover, about 50% of psychiatric disorders occurred earlier than AA.

CONCLUSIONS

AA is related to various psychiatric disorders. Onset age of AA is an important factor in the association with different comorbid psychiatric diseases. In addition to cosmetic impact, which may bring about anxiety or depression, stress neuroendocrine immunology may play an important role in the pathogenesis of both AA and psychiatric disorders.

Prevalence of nail biting and its association with mental health in a community sample of children

Background

This study evaluates onychophagia or nail biting (NB) prevalence and association with mental health of a community sample of children from Shiraz, Iran.

Findings

The parents of 743 primary school children, selected by random sampling, reported NB behavior of their children and themselves. Children's mental health problem was assessed using the Strengths and Difficulties Questionnaire (SDQ). 22.3% (95% CI: 19.3 to 25.3) of children had NB behavior in the last three months (girls: 20.1% (95% CI: 15.9 to 24.2). The rate in boys was 24.4% (95% CI: 20.1 to 28.7). 36.8% of the children with NB had at least one family member with nail biting. Older age was associated with a higher prevalence of NB while a higher score on the prosocial score was associated with a lower prevalence of NB.

Conclusions

NB is a very common behavior in both genders in children and their family members. Children with NB have less prosocial ability than those without it.

Psychiatric characterization of children with genetic causes of hyperandrogenism

OBJECTIVE

Very little is known about the mental health status in children with genetic causes of hyperandrogenism. This study sought to characterize psychiatric morbidity in this group.

DESIGN/METHODS

Children (8-18 years) with the diagnosis of classic congenital adrenal hyperplasia (CAH) or familial male precocious puberty (FMPP) underwent a semi-structured psychiatric interview, the Kiddie Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version. According to sex and the literature, incidence of identified psychopathology was compared between the two endocrinological groups. We evaluated 72 patients: 54 CAH (21 females) and 18 FMPP.

RESULTS

Twenty-four (44.4%) CAH patients and 10 (55.6%) FMPP patients met the criteria for at least one lifetime psychiatric diagnosis. Attention-deficit hyperactivity disorder (ADHD) was present in 18.2% of CAH males, 44.4% of FMPP males, and one case (4.8%) in CAH females. A high rate of anxiety disorders was also found in all the three groups (17-21%). Relative to females with CAH, the FMPP patients exhibited higher rates of ADHD. Age at diagnosis and the treatment modalities were not associated with psychopathology. Rates of psychiatric disorder, specifically ADHD and anxiety disorders, were higher than in the general population.

CONCLUSION

Although anxiety disorders may occur at an increased rate in children with chronic illness, androgens may contribute to higher risk for psychopathology in pediatric patients with genetic cause of excess androgen. Early diagnosis and treatment of childhood hyperandrogenism is essential for optimal development. The results suggest that assessment for psychiatric disorders should be part of the routine evaluation of these patients.

[Long-term follow-up of the efficacy of methotrexate alone or in combination with low doses of oral corticosteroids in the treatment of alopecia areata totalis or universalis]

BACKGROUND

Treatment of severe and chronic forms of alopecia areata (AA) totalis remains difficult. It has been suggested that methotrexate (MTX) is an efficacious treatment for AA totalis. The aim of our study was to assess the long-term safety and efficacy of MTX in patients with chronic severe forms of AA totalis.

PATIENTS AND METHODS

Thirty-three patients (24 women and nine men) with AA totalis or universalis were included. Mean disease duration was 7.7 years and these patients had not responded to prior standard treatment. The initial weekly dosage of MTX was 15 mg (n=2), 20mg (n=16) or 25mg (n=15). Nineteen patients (58%) were treated with MTX and low doses of corticosteroids (prednisone 10-20mg/d), while 14 patients (42%) received MTX alone. The primary end-point was complete hair regrowth under treatment.

RESULTS

Twenty-one patients had total hair regrowth and 13 patients were considered as treatment failures, with 10 of these having partial regrowth and three having no regrowth. Complete regrowth was seen in 12 of 19 patients (63%) on combined treatment and in eight of 14 patients (57%) on MTX alone. The onset of hair regrowth was noted after a median delay of 3 months. At the end of the study, after a median of 30 months' follow-up, the median cumulative dose of MTX was 1.8 g (400mg-5.5 g). Relapse was observed on corticosteroid dose reduction or withdrawal in 16 of the 20 patients in whom total hair regrowth initially occurred. Regrowth after treatment of relapse was seen in 14 of these 16 patients (87%). Seven patients experienced adverse events consisting of transient elevated transaminases (n=4), persistent nausea (n=2) and lymphocytopenia (n=1).

CONCLUSION

MTX alone or in combination with low doses of oral corticosteroids resulted in complete hair regrowth in about half of these patients presenting AA totalis or universalis. Lasting improvement required continuous treatment in most cases.
