Safety and efficacy of tofacitinib in 97 alopecia areata patients.

BACKGROUND: Alopecia areata (AA) is a recurrent immune-mediated disorder causing hair loss without any scarring being present. It affects hairs on the head or other parts of the body and can occur at any age and in both genders. It seems that AA is associated with a higher rate of psychological disorders resulting from hair loss and the esthetic and social repercussions of it. Common treatments like corticosteroids do not work for every patient and recent treatment options focusing on the immunologic mechanisms like tofacitinib have shown some promising results. METHODS: It's a retrospective study on patients with AA, AT, AU taking oral tofacitinib as a treatment for at least 6 months. Scalp hair loss was assessed before treatment and at each visit using the Severity of Alopecia Tool (SALT) score. RESULTS: Of 97 cases, 69.1% demonstrated over 50% SALT score improvement, with 44.3% having 90% or more decrease in SALT score. Patients who suffered from patchy AA were more responsive compared to patients with AT and AU subtypes and had a greater percent change in SALT score. Tofacitinib was tolerated quite well and no significant adverse events were reported. CONCLUSIONS: Tofacitinib should be taken into consideration as an efficacious treatment option for patients with AA, AT and AU.

Clinical and demographic characteristics associated with nail involvement in alopecia areata: A cross-sectional study of 197 patients.

Background and Aims: Alopecia areata (AA) is an immune-mediated nonscarring alopecia. Nail changes are a common disfiguring feature of AA with an average prevalence of 30%. We aimed to evaluate the frequency of different types of nail changes and determine demographic and clinical associations. Methods: This cross-sectional study included 197 AA patients. Demographic and clinical variables including the Severity of Alopecia Tool (SALT) score, type of AA, and nail changes were evaluated. Results: Among 197 AA patients with a mean age of 28.95 ± 14.45 years, 50.3% were female. Nail changes were detected in 165 patients (83.8%). The most frequent nail abnormalities were pitting (53.3%), linear line (46.7%), and distal notching (26.9%). AA patients with nail abnormalities were significantly younger than patients without nail changes (25.31 ± 14.96 vs. 32.22 ± 9.77 years; p < 0.001). Considering age groups, younger children (less than 10 years) were more likely to have nail changes than adults (97.1% vs. 76.5%; p < 0.001). The prevalence of linear line (69.6%) and distal notching (46.4%) were significantly higher in the universalis variant compared to other variants (p < 0.001). Pitting (54.5%), distal notching (43.9%), and koilonychia (12.1%) were the most common nail changes in severe forms compared to mild-to-moderate forms (p < 0.009). Conclusions: Our study revealed that young patients with severe disease are prone to nail abnormalities. Pitting, distal notching, and linear line were the most common nail changes. Of note, koilonychia, leukonychia, and red spots lunula are more expected in more severe AA.

Effects of age and sex on the comorbidities of alopecia areata: A cross-sectional hospital-based study.

Background and Aims: Alopecia areata (AA) is a common autoimmune nonscarring hair disorder with strong genetic links. It seems to be associated with several comorbidities affecting the AA treatment plan. On the other hand, the prevalence of comorbidities in different populations can be different based on genetic differences. This study aimed to clarify the association between age and sex with various comorbidities in AA patients. Methods: This cross-sectional study was conducted on 402 patients suffering from AA referred to our hospitals between 2018 and 2021. The clinical records of the patients were reviewed, including demographic and clinical information. Results: The most common diseases associated with AA were anxiety (36%), dermatitis (30%), hypothyroidism (9%), hyperlipidemia (5%), and vitamin D deficiency (4%). The most common comorbidities in AA patients over 18 years were allergic rhinitis, psychological problems, diabetes, hypertension, and hypothyroidism (p < 0.05). Hypothyroidism was more common in female patients than in male patients (p = 0.002). In contrast, hyperlipidemia was more common in male patients than in female patients (p = 0.024). There was a significant association between the severity of AA and hyperlipidemia and vitiligo (p = 0.003 and 0.045). Conclusion: Sex and age could affect comorbidities. The prevalence of hypothyroidism was higher in our study; it was higher in women than in men. Thyroid function tests were recommended for AA patients.

Hearing impairment in patients with alopecia areata.

Background Alopecia areata is an autoimmune disease that damages hair follicles and follicular melanocytes can be involved in the autoimmune process. Therefore, similar to vitiligo, there may be a relationship between sensorineural hearing loss and alopecia areata. Aims/objectives This study aimed to investigate potential hearing impairments in patients with alopecia areata. Methods A total of 42 subjects with alopecia areata and 42 healthy individuals enrolled in this cross-sectional study. The hearing was evaluated by vestibular evoked myogenic potential, otoacoustic emission and pure tone audiometry tests in the patients and control subjects. Results A normal otoacoustic emission was reported in 59.5% and 100% of subjects with alopecia areata and the controls, respectively (P = 0.02). Higher speech recognition thresholds (P = 0.02) and speech discrimination scores were reported more in subjects with alopecia areata than in controls (P < 0.001); however, the most comfortable level of speech was not significantly different between the groups (P = 0.06). The greatest increase in the hearing threshold was recorded at a frequency of 8000 Hz, while at frequencies of 500 and 1000 Hz, the patients and controls did not significantly differ (P > 0.05). About 6 (14.3%) and 2 (4.8%) of patients with unilateral and bilateral involvement, respectively, demonstrated no vestibular evoked myogenic potential response in the alopecia areata group. The patients and controls did not significantly differ in terms of amplitudes of the vestibular evoked myogenic potential test (P = 0.097). Limitation Small sample size and qualitative measurement of otoacoustic emission were limitations of our study. Conclusion Hearing loss was more common in alopecia areata patients than in healthy individuals. Follicular melanocytes may be involved in the alopecia areata inflammatory process, and destroying melanocytes may impact hearing function in the inner ear. However, there was no significant relationship between the duration and severity of alopecia areata and hearing loss.

Dermatologists Communication Skills and Performance From Point of View of Patients.

INTRODUCTION: Effective communication is an important issue in patient-doctor interaction which is even more important regarding chronic disorders which need a strong relationship between patient and clinician for better compliance and optimal control disease. OBJECTIVES: This study was aimed to develop the best cultural adapted Persian version of the 28-item Calgary- Cambridge Observation Guide (CCOG) questionnaire. METHODS: In this descriptive-analytic study, data collected from 400 patients attending the outpatient dermatology clinics of 3 major hospitals in Tehran using the modified Persian version of CCOG questionnaire, both before and after being visited by dermatologists. RESULTS: The difference of CCG scores for all of questions, except for questions number 1,16 and 22, was statistically significant. The highest score, both before and after visiting, attained by question regarding being respectful. The lowest scores for necessary behavior and the adequate amount of execution were related to questions number 3 (Introducing self) and 4 (Introducing role), respectively. Age and educational level of patients were significantly correlated with their expectations regarding communication skills of clinician. CONCLUSIONS: This study showed the acceptable validity of modified Persian version of CCOG-24 item questionnaire. Our findings also demonstrated that there was a significant difference between what patients expected from a dermatologist and the manner they actually were treated regarding physician communication skills.

Is the severity of alopecia areata associated with arterial stiffness?

Background: This study aimed to evaluate the severity of alopecia areata (AA) associations with metabolic syndrome, body composition evaluated by bioimpedance techniques, and arterial stiffness based on pulse-wave velocity analysis. Materials and Methods: This cross-sectional study was conducted on patients referred to AA Clinic at Razi Hospital in 2021 and 2022. Patients with AA with the Severity of Alopecia Tool (SALT) score above 20% and receiving no systemic therapy were included. Patient demographic and clinical information, symptoms of metabolic syndrome, and bioimpedance factors were collected, and the relationship between disease severity, metabolic syndrome, and bioimpedance indicators was evaluated. Results: In this study, 59 patients were examined, with 26 (44.07%) being female and 33 (55.93%) being male. The mean age of the patients was 37.42 years (standard deviation [SD] =11.28). The severity of the disease was assessed using the SALT score, with the mean severity in terms of the percentage being 69.83% (SD = 28.57%). In the regression model, SALT score was independently related to the severity of vascular stiffness after adjusting for the effect of other variables (beta = 0.033, 95% CI = 0.009-0.057, P = 0.046). Moreover, SALT score was significantly related to metabolic syndrome after adjusting for the effect of other variables (OR = 1.035, 95% CI = 1.012-1.059, P = 0.002). Conclusion: This study found that AA severity is associated with a higher chance of having metabolic syndrome and arterial stiffness which may lead to cardiovascular diseases in patients with AA, and screening patients regarding cardiometabolic diseases is mandated.

Treatment satisfaction and response in patients with severe alopecia areata under treatment with diphenylcyclopropenone.

Background and Aims: Alopecia areata (AA) is an autoimmune disease of hair follicles. Treatments currently include topical and intralesional corticosteroids and contact immunotherapy; however, the overall prognosis is usually unfavorable. In severe AA, topical immunotherapy with diphenylcyclopropenone (DPCP) is preferred. Since its effectiveness is heterogeneous and there are several side effects, we decided to measure the patients' satisfaction using the "Version II of the Treatment Satisfaction Questionnaire for Medication," which investigates satisfaction with effectiveness, side effects, convenience, and global satisfaction. Methods: We examined 100 patients under treatment with DPCP for treatment response, asked them to respond to the questionnaire, and calculated their overall scores out of 400. We then investigated the association between the patients' characteristics with their treatment response and satisfaction. Results: The overall satisfaction of patients was 257/400. We observed a significant association between patients' satisfaction scores on effectiveness and global satisfaction with their response to treatment (p < 0.001). The patients' satisfaction with the treatment's convenience had a significantly positive association with the age of receiving the diagnosis (p = 0.028). The overall treatment satisfaction was significantly associated with treatment response (276 vs. 213, p = 0.000). Conclusion: Although there are currently no gold standard treatments for severe AA, DPCP demonstrated a 71% response to treatment, and patients with response were significantly more satisfied with their treatment.

Topical treatment adherence and associated factors in patients with psoriasis: A single center, cross-sectional study.

Topical medications are one of the main treatments for psoriasis. Adherence to treatment is an important factor in achieving successful control of disease. The aim of this study was to evaluate adherence to topical drugs and identify possible associated factors in in patients with psoriasis. Ninety-three patients were evaluated by a two-part questionnaire; the first part examined demographic, socioeconomic and disease-related factors while the second part, the ECOB questionnaire (Elaboration d'un outil d'evaluation de l'observance des traitements medicamenteux), examined adherence to topical drugs. The mean self-reported adherence to topical treatment in this study, was 50.5%. Severe disease, involvement of lower extremity, and positive family history of psoriasis were associated with poor adherence to treatment. Patients with a history of diabetes mellitus had better adherence to treatment. In this study adherence to topical treatment was low and had no significant relationship with most of the studied demographic and socioeconomic factors.

A prospective comparative study of two regimens of diphenylcyclopropenone (DPCP) in the treatment of alopecia areata.

BACKGROUND: Alopecia areata (AA) is a chronic disorder and the best treatment regimen for it is unknown. Currently, one of the best documented treatment modalities for AA is topical immunotherapy. AIM: To evaluate the safety and efficacy of a novel method (multi-concentration patch test) versus standard protocol for topical immunotherapy. METHODS: A prospective randomized clinical trial was conducted on 30 patients with Alopecia areata, half of them received DPCP with a novel method using multi-concentration patch test to determine the optimal initiating concentration of DPCP (case group) and the other half experienced immunotherapy according to the standard protocol (control group). Percentage of hair regrowth after 6 months of treatment and the incidence of drug-related adverse effects were evaluated and compared between the two groups. (IRCT registration code: IRCT20141209020250N5). RESULTS: Absolute and relative hair regrowth percentages were reported 25% and 41.49% in case group and 8.2% and 14.21% in control group respectively. Considerable response (more than 75% hair regrowth) was observed in 4 (26.6%) patients in case and 1 (6.6%) patient in control group. The clinical response was initiated about 7 weeks sooner in case compared to the control group (14 versus 7.38 weeks, P: 0.001). Overall, clinical response was higher in patients received new protocol, compared to control group. Moreover, patients who experienced new protocol had a higher level of treatment satisfaction in comparison with patients having standard protocol (P: 0.012). CONCLUSION: This study revealed the effectiveness and safety of the novel multi-concentration patch test DPCP therapy for AA and its priority to conventional method, at least in terms of shortened duration of DPCP immunotherapy.

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.

A randomized trial of diphenylcyclopropenone (DPCP) combined with anthralin versus DPCP alone for treating moderate to severe alopecia areata.

BACKGROUND: Alopecia areata (AA) is a chronic autoimmune disorder. Finding the best treatment regimen for it remains a challenge. Currently, one of the best documented treatment modalities for AA is topical immunotherapy. AIM: To evaluate the safety and efficacy of combined DPCP and anthralin versus standard protocol (DPCP alone). METHODS: A prospective randomized clinical trial was conducted on 50 patients with Alopecia areata who received DPCP alone (group D) or in combination with anthralin (group D/A). Percentage of hair regrowth after 6 months of treatment and the incidence of drug-related adverse effects were evaluated and compared between the two groups. RESULTS: Complete hair regrowth was observed among three patients in each group (18.75% in Group D and 15.79% in Group D/A) after 6 months. Moreover, 25% and 31% of patients in group D and 21% and 47% of patients in group D/A had > 75% and > 50% hair regrowth respectively at the end of the study (P-value: 0.696). In addition, earlier age of onset, chronicity of lesions, nail involvement, facial hair loss and extensive lesions at baseline were associated with poor clinical outcome. CONCLUSION: DPCP and anthralin was as effective as DPCP alone and anthralin did not add to the effect of DPCP in treating AA.

Illness perception in patients with Alopecia areata under topical immunotherapy.

Alopecia areata (AA) is a chronic autoimmune-mediated disorder. There is little research on how AA patients conceptualize their disease. The purpose of this study was to investigate the perception and attitude of patients with AA about their illness. The cross-sectional study was performed on 102 patients with AA referred to our alopecia clinic. Patients between 16 and 60 years were enrolled in the study. A questionnaire including demographic and clinical characteristics and Illness Perception Questionnaire-Revised (IPQ-R) was administered to each patient. More than half of patients (55%) experienced their illness as a long-lasting (17.3 ± 5.5, median reference score = 18), and timely variable (13.4 ± 2.8, median reference score = 12) disorder. Patients perceived that their illness negatively affects their lives (18.9 ± 4.8, median reference score = 18) and are considered an effective role for themselves in controlling disease (20.3 ± 4.9, median reference score = 18). Moreover, patients had a fairly good accepting of their illness (13.4 ± 2.8, median reference score = 15). We observed significant negative effects of illness on the patient's emotions (21.5 ± 5.5, median reference score = 18). We also found that men had a stronger belief in personal control compared with women (21.5 ± 4.8 vs 19.5 ± 4.8; P = .03). A positive correlation was observed between educational status and illness coherence (r = .21; P = .03). Most patients with AA considered undesirable consequences of their illness. High scores of negative affective symptoms indicate the harmful effects of this disease on patients' lives leading to problems of mental health.

Utility of Dermoscopic Evaluation in Predicting Clinical Response to Diphencyprone in a Cohort of Patients with Alopecia Areata.

BACKGROUND: Alopecia areata (AA) is a chronic and inflammatory disease of hair follicles, causing nonscarring alopecia. While the various types of treatment have been investigated, the definite cure for AA has not been established yet. OBJECTIVES: The objective of this study is to evaluate the clinical and dermoscopic features of patients with AA to identify the factors with prognostic values in diphenylcyclopropenone (DPCP) response rate. METHODS: Eighty patients with AA were included, and baseline hair loss was calculated based on the severity alopecia tool (SALT) score. The characteristic dermoscopic features of AA were evaluated by two skilled dermatologists separately at baseline, 12 and 24 weeks afterward. RESULTS: The mean SALT score in the 1st, 12th, and 24th week was 77 ± 24.7, 80 ± 27, and 71 ± 35.6, respectively, which were not significantly different over this time period (P = 0.085). SALT score correlated negatively with the short vellus hair/field (ρ = -0.361, P = 0.02), broken hair/field (ρ = -0.317, P = 0.044), and tapering hair/field (ρ = -0.388, P = 0.012) in the 1st week. Forty-one patients continued treatment courses over 24 weeks. Six patients had good response, 11 achieved partial response, and 24 had no hair regrowth. Statistically significant correlation was observed between treatment response and duration of disease (P = 0.04), frequency of relapses (P = 0.033), type of alopecia, and number of black dots (P = 0.028). The mean for all dermoscopic findings showed descending process during our three follow-up sessions which was statistically significant for black dot (P = 0.015) and broken hair (P = 0.006). CONCLUSION: The number of black dot per field initially was negatively correlated to DPCP therapy and the frequency of dermoscopic findings reduced during the treatment process.

Estimated cut-off values for pemphigus severity classification according to pemphigus disease area index (PDAI), autoimmune bullous skin disorder intensity score (ABSIS), and anti-desmoglein 1 autoantibodies.

BACKGROUND: Pemphigus is a potentially fatal disease if left untreated. Valid scoring systems and defined cut-off values for classification of patients would help with better management through specified pharmaceutical and non-pharmaceutical treatments. METHODS: In this study, pemphigus patients who were receiving immunosuppressive treatments and had recent disease relapse were recruited for examination of pemphigus disease area index(PDAI), autoimmune bullous skin disorder intensity score (ABSIS), physician global assessment (PGA), autoimmune bullous disease quality of life (ABQoL), anti-desmoglein 1 (anti-Dsg1), and anti-Dsg3 autoantibody titers from December-2017 to February-2018. Cut-off values were estimated using model-based clustering classification and the 25th and 75th percentiles approach, performed separately for the exclusive cutaneous, exclusive mucosal, and mucocutaneous groups. RESULTS: In the 109 included patients, the 25th and 75th percentiles cut-offs were 6.2 and 27 for PDAI score, and 4 and 29.5 for ABSIS score. The model-based analysis resulted in two groups (cut-point:15) for PDAI score, and three groups (cut-points:6.4 and 31.5) for ABSIS score. The groups were significantly different for the PDAI, ABSIS, PGA, and ABQoL values. Based on anti-Dsg1 autoantibody values, the model-based analysis cut-point was 128 and the 25th and 75th percentiles cut-offs were 98 and 182. Anti-Dsg3 autoantibody values did not differentiate between pemphigus severity classes. CONCLUSIONS: Estimated cut-off values based on the anti-Dsg1 level, PDAI, and ABSIS scoring systems could be used to classify patients into different severity grades for better management and prognosis.
