RESUMEN

BACKGROUND: Non-motor symptoms in myasthenia gravis (MG) are rarely confirmed. Although there are some small cohort studies, a large-systemic survey has not yet been performed. METHODS: We investigated the incidence and clinical characteristics of patients with MG who had taste disorders and alopecia using data of 1710 patients with MG enrolled in the Japan MG Registry 2021. RESULTS: Among them, 104 (6.1%) out of 1692 patients and 138 (8.2%) out of 1688 patients had histories of taste disorders and alopecia, respectively. Among the patients with MG, taste disorders were significantly more common in women, those with severe symptoms, refractory MG, or thymoma-associated MG, and were less common in those with ocular MG. The taste disorders often occurred after the onset of MG and often responded to MG treatments. Alopecia was more common in MG patients with a history of bulbar palsy and thymoma, and it often occurred before the onset of MG and sometimes responded to MG treatments. Multivariate logistic regression analysis revealed taste disturbance was associated with worst quantitative MG score and thymoma-associated MG; and alopecia was associated with thymoma-associated MG. CONCLUSION: Clinicians should be aware of the non-motor symptoms in MG, especially in patients with severe myasthenic symptoms and thymoma-associated MG.

RESUMEN

Background and objective Alopecia areata (AA) is a reiterative and nonscarring type of hair loss that can affect any hairy area of the body, particularly the scalp. It manifests as patchy or confluent hair loss with variations in demographics and ethnicity. There are numerous treatment options available, including topical and systemic steroids, topical minoxidil, dithranol, tacrolimus, psoralen and ultraviolet therapy (PUVA), contact immunotherapy, and oral immunosuppressive drugs. However, no previous contrast for efficacy is present between the topical betamethasone versus topical minoxidil alone in our population. This study aims to compare the efficacy of topical betamethasone dipropionate versus topical minoxidil in patients with AA. Methodology A nonrandomized controlled study was conducted at the Department of Dermatology, Jinnah Hospital Lahore, incorporating the data of patients between July 26, 2016, and January 26, 2017, after obtaining institutional ethical approval. One hundred patients with alopecia, either on the scalp or any other hairy part, from both genders, aged between 18 and 50 years, were included in the study. Two groups were created, and patients were assigned to these groups based on the clinician's choice. Group A patients were administered betamethasone dipropionate (0.05%) lotion twice daily on affected areas for 12 weeks. Group B patients were administered minoxidil (5%) solution twice daily on affected areas for 12 weeks. A four-week follow-up plan was followed. A five-point scale score system was used for alopecia grading. After 12 weeks, the hair regrowth score (RGS) was used to compare the efficacy of treatment between the two groups. Results A total of 100 patients with grades S1 to S3 AA of less than three months duration were enrolled. Two groups were created, with 50 patients in each group. The mean age in Group A was 29.08 ± 6.51 years, while in Group B, it was 29.38 ± 6.62 years. In Group A, there were 76% males and 24% females, while in Group B, there were 74% males and 26% females. Comparison of efficacy of topical betamethasone dipropionate versus topical minoxidil in patients with AA demonstrated a greater efficacy of 74% (Grade 3 and Grade 4 responses) in Group A, while in Group B, only 42% of patients showed efficacy. A statistically significant difference was found, with a P-value of 0.001. No serious side effects were noted. Conclusions Our study concluded that topical betamethasone dipropionate (0.05%) lotion has statistically significantly higher efficacy compared to topical minoxidil (5%) solution in patients with AA.

RESUMEN

Minoxidil is a widely utilized medication androgenic alopecia. An original investigation on its potential to cause hair darkening in treated people is lacking. We conducted an observational study using two face-validated questionnaires that dermatologists altered to assess minoxidil's hair discolouration risk. This Saudi Arabian survey collected data in October and November 2022. One questionnaire targeted the population, while the other targeted dermatologists. Survey 1 included 453 patients, 56.7% of whom were 18-24 and mostly female. It's interesting that 26% (n=118) detected hair greying and 14.8% (n=67) noticed other color changes. With P-values of 0.0001, longer-term minoxidil users and those with a family history of hair greying had higher hair discolouration. Dermatologists completed Survey 2 (57 participants). Nearly 60% of dermatologists have ten years of experience. 42.1% of dermatologists saw grey hair after minoxidil use. 17.5% of doctors blame minoxidil for hair graying. This observational study examined the data of over 400 patients to determine if minoxidil could cause hair discoloration. Based on the data, we hypothesize that this drug may cause hair discoloration with prolonged use and in people with a family history of hair greying.

RESUMEN

OBJECTIVE: Alopecia areata (AA) is often characterized by sudden onset of patchy hair loss. Topical corticosteroid injection is the most common treatment. This study retrospectively observed the clinical efficacy of microneedle minoxidil combined with triamcinolone acetonide in the treatment of AA. METHODS: A total of 230 patients with AA were selected. The experimental group (n = 120) received physician training and home microneedle treatment with minoxidil combined with triamcinolone acetonide once a week. Topical minoxidil and triamcinolone acetonide were used twice daily at other times. The control group (n = 110) was treated with minoxidil combined with triamcinolone acetonide, twice a day. Cure rate, response rate, SALT, dermatological Quality of Life Index (DLQI), visual analogue (VAS), and cost were assessed at weeks 4 and 12. RESULTS: Treated group SALT score(Severity of Alopecia Tool) remarkable lower than control group after treated 4 and 12 weeks. After 12 weeks treatment, DLQI score of the treated group (1.8 ± 1.67) were significantly lower than those of the control group (2.45 ± 1.88) (p < 0.05). VAS score and adverse reaction between two group showed no significant different (p = 0.823, p = 0.484 respectively). The total cost was 53.93 ± 15.85 in the treatment group and 53.26 ± 11.51 in the control group. There was no significant difference between the two groups (p = 0.72). In the treated group, the complete response rate (CR: 78.33%) and total effective rate (CR+PR: 95%) were significantly higher than those in the control group (CR: 40.91% and CR+PR: 51.82%), with statistically significant differences (p < 0.001). CONCLUSION: Microneedle introduction of minoxidil and triamcinolone acetonide in the treatment of AA is a safe, effective, economical, and convenient method, with few adverse reactions, and has a good application prospect.

RESUMEN

BACKGROUND: Stromal vascular fraction (SVF) cells derived from adipose tissue and platelet-rich plasma (PRP) are among novel treatments for androgenetic alopecia (AGA). We aimed to investigate the effect of adding SVF to PRP and compare it to administering PRP injection alone. METHODS: Eighteen patients were randomly divided into two groups of nine. The PRP group was treated with PRP at all three visits at 1-month intervals, while the SVF-PRP group received an SVF injection on the first visit and a PRP injection on the second and third visits. Each group was evaluated at baseline and 20 weeks after the therapy's initiation. RESULTS: Changes in mean hair diameter and hair count compared to baseline were significant in both groups. The PRP group experienced a greater increase in mean hair count than the SVF-PRP group, and the SVF-PRP group had a marginally greater increase in hair diameter than the PRP group. These differences were not statistically significant compared to each other. The patient and physician assessment scores exceeded the mean (on a scale from 0: poor to 3: excellent) in both groups. CONCLUSION: Adding one SVF injection to two PRP treatment sessions versus three PRP injections alone had no significant difference in evaluated variables. If additional research demonstrates the same results, we suggest that multiple SVF injection sessions may be required to produce a statistically significant difference compared to PRP injection alone. Moreover, considering lower cost and greater accessibility of PRP, it can be used before SVF in the treatment of AGA.

RESUMEN

JAK-STAT signalling pathway inhibitors have emerged as promising therapeutic agents for the treatment of hair loss. Among different JAK isoforms, JAK3 has become an ideal target for drug discovery because it only regulates a narrow spectrum of γc cytokines. Here, we report the discovery of MJ04, a novel and highly selective 3-pyrimidinylazaindole based JAK3 inhibitor, as a potential hair growth promoter with an IC50 of 2.03 nM. During in vivo efficacy assays, topical application of MJ04 on DHT-challenged AGA and athymic nude mice resulted in early onset of hair regrowth. Furthermore, MJ04 significantly promoted the growth of human hair follicles under ex-vivo conditions. MJ04 exhibited a reasonably good pharmacokinetic profile and demonstrated a favourable safety profile under in vivo and in vitro conditions. Taken together, we report MJ04 as a highly potent and selective JAK3 inhibitor that exhibits overall properties suitable for topical drug development and advancement to human clinical trials.

RESUMEN

INTRODUCTION: Alopecia areata (AA) affects approximately 2% of the general population and is associated with significant psychosocial morbidity and poor health-related quality of life. Despite the high incidence of the disease the available clinical practice guidelines to help clinicians and improve patients' care are very poor and of a low methodological quality, as compared to other high-burden dermatoses. The aim of this survey is to capture the current clinical practice in AA management, as performed by dermatologists, in two Mediterranean countries to identify potential disparities and gaps in diagnosis and treatment. METHODS: A 50-item questionnaire was created in the English language and then translated into Greek and Italian language and sent to the Greek and Italian dermatologists via email. RESULTS: A total of 490 dermatologists from Italy and 234 from Greece participated in the survey. The diagnosis of AA is usually based on history and clinical examination, supported by trichoscopy. The rate of use of severity scores and scales to evaluate impact on quality of life by dermatologists was low. Treatment of patchy AA, in both adult and pediatric populations, is based on use of topical steroids as first-line treatment. Results on special site involvement (eyebrows, beard, and ophiasis), chronic cases, and the pediatric population highlight extreme heterogeneity in treatment approach. CONCLUSIONS: Our results highlight that management of AA, in terms of diagnosis and treatment, is still challenging.

RESUMEN

INTRODUCTION: Alopecia areata (AA) is an autoimmune skin disease presenting as nonscarring hair loss. Information on the epidemiology of AA, especially the occurrence of AA and its subtypes within the general population, is scarce. The study aimed to estimate the incidence rates and prevalence of hospital-treated AA and its subtypes in Denmark and to examine the demographic and clinical characteristics of patients with AA, including comorbidities and use of prescription medications. METHODS: This was a cohort study based on data from administrative and health registers in Denmark in 1995-2016. The study included individuals who were (1) registered with a hospital inpatient or hospital-based outpatient clinic diagnosis of AA between 1995 and 2016 in the Danish National Patient Registry covering encounters at all Danish hospitals, (2) alive and resided in Denmark anytime between 1995 and 2016, (3) aged ≥ 12 years, and (4) resided uninterrupted in Denmark during the 12 months before the first AA diagnosis during the study period. RESULTS: During the study period, 2778 individuals with an incident hospital-based diagnosis of AA were identified; 63.1% were female and 28.7% of the patients were aged ≥ 50 years. Over the study period, the overall incidence rate for any hospital-treated AA per 100,000 person-years was 2.62 (95% confidence interval [CI], 2.53-2.72), and the overall prevalence in 2016 was 71.7 (95% CI 69.4-74.1) per 100,000 persons. Both incidence rate and prevalence increased over time. Prevalence of most hospital-treated comorbidities or history of medication use was below 10% and was similar in the alopecia totalis (AT)/alopecia universalis (AU) and non-AT/AU subtypes of AA. CONCLUSION: This cohort study reported incidence rates and prevalence over time and characteristics of individuals with hospital-treated AA in Denmark, which are in agreement with those previously reported in this population.

RESUMEN

We performed a Bayesian network meta-analysis to indirectly compare the relative efficacy and safety of the latest JAK inhibitors for moderate-to-severe alopecia areata (AA). 13 trials totaling 3,613 patients were included. Two low-dose groups of oral formulations (ritlecitinib 10mg and ivarmacitinib 2mg) and two topical formulations (delgocitinib ointment and ruxolitinib cream) appeared to be relatively ineffective against moderate-to-severe AA. Ranking analysis suggested that brepocitinib 30mg has the best relative effect in reducing the SALT score (sucra = 0.9831), and demonstrated comparable efficacy to deuruxolitinib 12mg (sucra = 0.9245), followed by deuruxolitinib 8mg (sucra = 0.7736). Regarding the SALT50 response, brepocitinib 30mg ranked highest (sucra = 0.9567), followed by ritlecitinib 50mg (sucra = 0.8689) and deuruxolitinib 12mg (sucra = 0.7690). For achieving the SALT75 response, deuruxolitinib 12mg had the highest probability (sucra = 0.9761), followed by deuruxolitinib 8mg (sucra = 0.8678) and brepocitinib 30mg (sucra = 0.8448). Deuruxolitinib 12mg might be the most effective therapy for patients with severe AA (sucra = 0.9395), followed by ritlecitinib 50mg (sucra = 0.8753) and deuruxolitinib 8mg (sucra = 0.8070). Deuruxolitinib 12mg/8mg demonstrated notable efficacy for moderate-to-severe AA, and is expected to be a new treatment option for AA. It was worth noting that deuruxolitinib exhibit a greater likelihood of causing adverse events in comparison to other JAK inhibitors. Ritlecitinib 50mg seemed to exhibit fewer adverse effects in the high-dose groups of oral JAK inhibitors and might be an optimal choice to balance safety and efficacy. The majority of JAK inhibitors exhibited acceptable short-term safety profiles. To enhance the applicability and accuracy of our research, further head-to-head trials with longer follow-up periods are needed. Systematic Review Registration: identifier [CRD42022368012].

RESUMEN

We report a case of persistent gynecomastia in a healthy 20-year-old man after 1 month of low-dose finasteride. Finasteride was discontinued after 2 months, and gynecomastia was unchanged 5 months after drug withdrawal. The gynecomastia regressed but did not resolve after 6 months of treatment with raloxifene, a selective estrogen receptor modulator. One year later, bilateral mammoplasty was performed to remove the remaining breast tissue. Finasteride, a 5-alpha-reductase inhibitor, is widely used for the treatment of androgenetic alopecia. Gynecomastia is an expected side effect of this therapy given its mechanism of action. However, only 8 cases of gynecomastia have been reported with low-dose (1 mg daily) finasteride treatment since its approval for androgenetic alopecia in 1997. This raises the concern that gynecomastia resulting from low-dose finasteride is significantly underreported, causing inadequately informed patients. Further, because of the risk of gynecomastia, it is important for prescribing physicians to counsel patients regarding this complication and to consider early intervention when finasteride-induced gynecomastia first arises to prevent fibrosis and thus irreversible gynecomastia.

RESUMEN

INTRODUCTION: Androgenetic alopecia (AGA) is the most prevalent cause of male hair loss, often requiring medical and/or surgical intervention. The US FDA has approved topical minoxidil and oral finasteride for male AGA treatment. However, some AGA patients fail to respond satisfactorily to these FDA-approved treatments and/or may experience side effects, based on their individual profiles. To mitigate the shortcomings of these treatments, researchers are now exploring alternative treatments such as newer 5-α reductase inhibitors (5-ARIs) and androgen receptor antagonists (ARAs). AREAS COVERED: This article reviews the safety and effectiveness of well-known 5-α reductase inhibitors (5-ARIs) like finasteride and dutasteride, as well as the newer 5-ARIs, emerging androgen receptor antagonists (ARAs), and natural products such as saw palmetto and pumpkin seed oil in the treatment of male AGA. EXPERT OPINION: Although several newer 5-ARIs, ARAs, and natural products have exhibited promise in clinical trials, additional research is essential to confirm their safety and efficacy in treating male AGA. Until additional evidence is available for these agents, the preferred treatment choices for male AGA are the FDA-approved treatments, topical minoxidil, and oral finasteride.

RESUMEN

BACKGROUND: Androgenetic alopecia (AGA) is a major cause of hair loss resulting from a complex interplay between various genes and hormones with the result being follicular miniaturization and altered hair cycle dynamics. Platelet-rich plasma (PRP) has a well-established role as adjunctive therapy in AGA but there are many limitations of it. In an attempt to overcome the shortcomings of PRP, liquid platelet-rich fibrin (PRF) was developed. AIM: This article critically reviews the protocol for the preparation and clinical outcomes of PRF. PATIENTS/METHODS: The articles published so far in the English language regarding the preparation and clinical outcomes of PRF were reviewed. RESULTS: Among five studies analyzing various centrifugation speeds and centrifugation times, three of the studies favored low-speed centrifugation, whereas two studies did not support this methodology. A horizontal centrifuge may be preferred over a fixed-angle centrifuge for PRF. Five clinical studies on the use of PRF showed a significant effect on AGA. CONCLUSION: At present, there is no consensus regarding the preparation of PRF. Most studies used fixed-angle centrifugation favored low centrifuge speed and less centrifugation time. Larger studies are needed to determine the optimal centrifugation force and time. A horizontal centrifuge may be preferred over a fixed-angle centrifuge due to the higher yield of platelets, and lesser shear trauma to the cells. In addition, larger, well-designed studies are needed to confirm the benefits of PRF over PRP.

RESUMEN

INTRODUCTION: Alopecia areata (AA) is an autoimmune disease induced by viral infection or vaccination. With the increased incidence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the incidence of AA has also increased. Recently the incidence was found to be 7.8% from a previously reported rate of 2.1%. The physical and psychological damage caused by AA could seriously affect patients' lives, while AA is a challenging dermatological disease owing to its complex pathogenesis. AREAS COVERED: This paper presents a comprehensive review of the prevalence, pathogenesis and potential therapeutic targets for AA after infection with SARS-CoV-2 or SARS-CoV-2 vaccine. EXPERT OPINION: The treatment of AA remains challenging because of the complexity of its pathogenesis. For patients with AA after SARS-CoV-2 infection or vaccination, the use of sex hormones and alternative regenerative therapies may be actively considered in addition to conventional treatments. For preexisting disease, therapeutic agents should be adjusted to the patient's specific condition.

RESUMEN

Background: Non-scarring alopecia is typically represented by two main types: alopecia areata (AA) and androgenetic alopecia (AGA). While previous observational studies have indicated a link between non-scarring alopecia and hypothyroidism, the precise causal relationship remains uncertain. To determine the potential links between non-scarring alopecia and hypothyroidism, we conducted a bidirectional two-sample Mendelian randomization (MR) analysis. Methods: We used independent genetic instruments from the FinnGen consortium for AA (682 cases, 361,140 controls) and AGA (195 cases, 201,019 controls) to investigate the association with hypothyroidism in the UK Biobank study (22,687 cases, 440,246 controls). The primary analysis was performed using the inverse variance-weighted method. Complementary approaches were employed to evaluate the pleiotropy and heterogeneity. Results: Genetically predicted AA exhibited a positive causal effect on hypothyroidism (odds ratio [OR], 1.0017; 95% confidence interval [CI], 1.0004-1.0029; P = 0.0101). Additionally, hypothyroidism was found to be strongly correlated with an increase in the risk of AA (OR, 45.6839; 95% CI, 1.8446-1131.4271, P = 0.0196). However, no causal relationship was demonstrated between AGA and hypothyroidism. A sensitivity analysis validated the integrity of these causal relationships. Conclusion: This MR study supports a bidirectional causal link between AA and hypothyroidism. Nevertheless, additional research is needed to gain a more thorough comprehension of the causal relationship between non-scarring alopecia and hypothyroidism.

RESUMEN

Androgenetic alopecia (AGA) is a prevalent disease in worldwide, local application or oral are often used to treat AGA, however, effective treatments for AGA are currently limited. In this work, we observed the promoting the initial anagen phase effect of pilose antler extract (PAE) on hair regeneration in AGA mice. We found that PAE accelerated hair growth and increased the degree of skin blackness by non-invasive in vivo methods including camera, optical coherence tomography and dermoscopy. Meanwhile, HE staining of sagittal and coronal skin sections revealed that PAE augmented the quantity and length of hair follicles, while also enhancing skin thickness and hair papilla diameter. Furthermore, PAE facilitated the shift of the growth cycle from the telogen to the anagen phase and expedited the proliferation of hair follicle stem cells and matrix cells in mice with AGA. This acceleration enabled the hair follicles to enter the growth phase at an earlier stage. PAE upregulated the expression of the sonic hedgehog (SHH), smoothened receptor, glioma-associated hemolog1 (GLI1), and downregulated the expression of bone morphogenetic protein 4 (BMP4), recombinant mothers against decapentaplegic homolog (Smad) 1 and 5 phosphorylation. This evidence suggests that PAE fosters hair growth and facilitates the transition of the growth cycle from the telogen to the anagen phase in AGA mice. This effect is achieved by enhancing the proliferation of follicle stem cells and matrix cells through the activation of the SHH/GLI pathway and suppression of the BMP/Smad pathway.

RESUMEN

BACKGROUND: Accurately identifying alopecia in claims data is important to study this rare medication side effect. OBJECTIVES: To develop and validate a claims-based algorithm to identify alopecia in women of childbearing age. METHODS: We linked electronic health records from a large healthcare system in Massachusetts (Mass General Brigham) with Medicaid claims data from 2016 through 2018 to identify all women aged 18 to 50 years with an ICD-10 code for alopecia, including alopecia areata, androgenic alopecia, non-scarring alopecia, or cicatricial alopecia, from a visit to the MGB system. Using eight predefined algorithms to identify alopecia in Medicaid claims data, we randomly selected 300 women for whom we reviewed their charts to validate the alopecia diagnosis. Positive predictive values (PPVs) were computed for the primary algorithm and seven algorithm variations, stratified by race. RESULTS: Out of 300 patients with at least 1 ICD-10 code for alopecia in the Medicaid claims, 286 had chart-confirmed alopecia (PPV = 95.3%). The algorithm requiring two diagnosis codes plus one prescription claim for alopecia treatment identified 55 patients (PPV = 100%). The algorithm requiring 1 diagnosis code for alopecia plus 1 procedure claim for intralesional triamcinolone injection identified 35 patients (PPV = 100%). Across all 8 algorithms tested, the PPV varied between 95.3% and 100%. The PPV for alopecia ranged from 94% to 100% in White and 96%-100% in 48 non-White women. The exact date of alopecia onset was difficult to determine in charts. CONCLUSION: At least one recorded ICD-10 code for alopecia in claims data identified alopecia in women of childbearing age with high accuracy.

RESUMEN

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.
