The Pathogenesis and Treatment Progress of Androgenic Alopecia

Androgenic alopecia, also known as seborrheic alopecia, is the most common hair loss disorder in dermatology clinics, mainly characterized by hair follicle miniaturization and progressive hair loss. The etiology and pathogenesis of androgenic alopecia are not clear, but may be related to heredity and androgen metabolism. Currently, minoxidil and finasteride are the only two drugs approved by the U.S. Food and Drug Administration (FDA) for AGA treatment, other treatments include oral minoxidil, hair transplantation, low energy laser therapy (LLLT), platelet-rich plasma (PRP), Chinese medicine microneedles, and combination therapy. With the development of medicine and science, we have ushered in the era of biologics and targeted therapy. In recent years, a variety of signaling pathways for androgenic alopecia have been found, which may provide a basis for targeted therapy for androgenic alopecia.

Hair regrowth following fecal microbiota transplantation in an elderly patient with alopecia areata: A case report and review of the literature

BACKGROUND Alopecia areata is a hair loss disease associated with genetics,autoimmunity,and other factors.There is an intriguing link between alopecia areata and gut dysbiosis.Fecal microbiota transplantation(FMT)has been recommended to treat Clostridium difficile(previously known as Clostridioides difficile)infection,and has also shown potentials in the treatment of inflammatory bowel disease,irritable bowel syndrome,and non-alcohol fatty liver disease.CASE SUMMARY An 86-year-old man,with a history of sigmoid colon carcinoma,suffered from recurrent abdominal pain and distension,and diarrhea for six months,with inappetence.At admission,he was also diagnosed with depression.Upon physical examination,the patient presented with a 1.5 cm×2.0 cm alopecia areata on his right occiput.Due to the negative results of laboratory testing,capsule endoscopy,and colonoscopy,the patient was diagnosed with noninfectious diarrhea,depressive disorder,and patchy alopecia areata.Considering that noninfectious diarrhea in the elderly patient was mainly caused by gut dysbiosis,he was given six rounds of FMT.His diarrhea improved remarkably one month after FMT,with improved appetite and disappearance of abdominal pain,distension,and depressive symptoms.Surprisingly,he reported new hair growth on the affected region of his scalp,with some of his white hair gradually turning to black,without taking any other therapies for alopecia areata before and after FMT.CONCLUSION FMT might act as a potential therapy for patients who suffer from alopecia areata.Large and well-designed studies are required to confirm the role of FMT in alopecia areata.

Cure of alopecia areata after eradication of Helicobacter pylori:A new association?

Alopecia areata is a disease of the hair follicles, with strong evidence supporting autoimmune etiology. Alopecia areata is frequently associated with immune-medi- ated diseases with skin manifestations such as psoriasis and lichen planus, or without skin manifestations such as autoimmune thyroiditis and idiopathic thrombocytopenic purpura. Helicobacter py/ori （H. pylorl） infection is present in around 50% of the world＇s population and has been associated with a variety of immune-mediated extra-digestive disorders including autoimmune thyroid- itis, idiopathic thrombocytopenic purpura, and psoriasis. A case of a 43-year old man with an 8-too history of alopecia areata of the scalp and beard is presented. The patient was being treated by a dermatologist and had psychiatric support, without any improvement. He had a history of dyspepsia and the urea breath test confirmed H. pylori infection. The patient went into remission from alopecia areata after H. pylori eradication. If such an association is confirmed by epidemiological studies designed for this purpose, new therapeutic options could be available for these patients, especially in areas where infection with H, pylori is highly prevalent.

Breeding and preliminarily phenotyping of a congenic mouse model with alopecia areata

In the current study, the alopecia areata gene was introduced into the C57BL/6 （B6） mouse through repeated backcrossing/intercrossing, and the allelic homozygosity of congenic AAtJmice （named B6.KM-AA） was verified using microsatellites. The gross appearance, growth characteristics, pathological changes in skin, and major organs of B6.KM-AA mice were observed. Counts and proportions of CD4＋ and CD8＋ T lymphocytes in peripheral blood were determined by flow cytometry. Results show that congenic B6.KM-AA mice were obtained after 10 generations of backcrossing/intercrossing. B6.KM-AA mice grew slower than B6 control mice and AA skin lesions were developed by four weeks of age. The number of hair follicles was reduced, but hair structures were normal. Loss of hair during disease progression was associated with CD4＋ and CD8＋ T lymphocytes infiltration peri- and intrahair follicles. No pathological changes were found in other organs except for the skin. In the peripheral blood of B6.KM-AA mice, the percentage of CD4＋ T cells was lower and percentage of CD8＋ T cells higher than in control mice. These findings indicate that B6.KM-AA mice are characterized by a dysfunctional immune system, retarded development and T-cell infiltration mediated hair loss, making them a promising new animal model for human alopecia areata.

TREATMENT OF 42 CASES OF ALOPECIA AREATA WITH PLUM-BLOSSOM NEEDLE

Professor Yanping Bai’s experience in treating alopecia areata

To summarize and analyze Professor Bai Yanping’s clinical experience in treating alopecia areata.Prof.Bai thinks the etiology of alopecia areata is a combination of liver-kidney depletion,qi and blood deficiency,qi stagnation and blood stasis,always along with wind-heat,damp-heat,blood heat and insomnia.It is indispensable to enrich and nourish the liver and kidney,supplement and nourish the qi and blood,invigorate blood and dissolve stasis,and at the same time,the usage of messenger drug and plum-blossom needle is important and formula has to vary from person to person on the basis of commonality.

Targetoid Polycyclic Concentric Hair Regrowth Pattern Is a Sign of Immunological Recovery in Alopecia Areata

Background: Alopecia areata is a common autoimmune disease, where there are many topical and systemic therapies, during which hair growth appears in a uniform pattern. In certain cases, hair regrowth takes a polycyclic pattern simulating a target, so called targetoid phenomena. Objective: To screen all cases of treated alopecia areata for hair targetoid regrowth pattern. ?Methods: This is an observational study, was conducted in Dermatology Department of Baghdad Teaching Hospital in Iraq, during the period, August 2017 to October 2017. All cases treated for alopecia areata with IM triamcinolone 20 - 40 mg injection every 2 weeks with topical clobetasone ointment and zinc sulfate 2 mg/kg/day for 2 months, were examined for the targetoid concentric hair regrowth pattern. Result: Among all cases of alopecia areata, seven patients were recorded to have the targetoid concentric hair pattern, which seen 2 - 4 weeks after therapy, their ages ranged from 4 to 25 years old with a mean 14.5, all of them were males. All these patients returned back with hair growth in a form of rings of hair growth alternating with rings of little or no hair growth forming a typical picture of target. Conclusion: Targetoid polycyclic concentric hair regrowth pattern is an important phenomenon seen in patients receiving treatment for alopecia areata, which is a good sign of recovery where its etiopathogenesis could not well be elucidated but alternating immunological reactions could explain this targetoid pattern.

HLA antigens in individuals with down syndrome and alopecia areata

AIM: To describe human leukocyte antigen(HLA) alleles in individuals with Down syndrome and alopecia areata. METHODS: A cross-sectional study was conducted, which evaluated 109 individuals. Ten with down syndrome(DS) and alopecia areata(AA), ten with DS without AA and ten with AA without DS, and their fami-lies. The individuals were matched by gender and age. The following data were computed: gender, age, ethnic group, karyotype, clinical presentation and family history of alopecia areata. Descriptive analysis: measures of central tendency and frequency distribution. Inferential analysis: Fisher's exact test to compare categorical data between the three groups and Kruskal-Wallis ANOVA test for numerical data.RESULTS: Seventy per cent of evaluated individuals in the DS and AA group were male; presented mean age of 18.6(SD ± 7.2) years and 70% were Caucasian. We observed involvement of the scalp, with a single lesion in 10% and multiple in 90% of subjects. It was observed that there is no significant difference in the frequency distributions of the alleles HLA loci A, B, C, DRB1 and DQB1 of subjects studied. However, according to Fisher's exact test, there is a trend(P = 0.089) of DS group to present higher proportions of HLA-A 36 and HLA-B 15 than the AA group and AA and DS group.CONCLUSION: There was a tendency for the DS group, to present proportion of HLA-A 36 and HLA-B 15 higher than the AA group and group of individuals with AA and DS. However, there was no significant difference in the frequency distribution of the alleles.

朱仁康治疗斑秃经验

斑秃是皮肤科门诊中最常见的脱发疾病之一,本病影响美观,愈后容易复发,给部分患者带来严重心理负担。朱仁康认为斑秃多由情志异常引起气血失和,继而引动内风所致。治风先治血,强调从血论治,临证根据斑秃病情进展,辨证治疗分三期三证:急性进展期多属血热生风证,以凉血为主;缓解恢复期多属血虚生风证,以养血为主;慢性期及全秃、普秃多属血瘀生风证,以活血为主。

巴瑞替尼治疗新冠疫苗接种后弥漫性斑秃一例

本文报道一例巴瑞替尼成功治疗新冠疫苗接种后发生弥漫性斑秃的患者,给予巴瑞替尼每日4 mg,治疗6个月后停药,新生白色短发,停药1个月后,白发转为黑发。停药后随访10个月,至今仍未复发。

基于“形气神一体观”探讨斑秃的诊疗思路

形气神一体观是中医整体观念的表现,也是中医独特地从物质形态、能量功能、精神思维三个层面探索人体的认知体系。斑秃作为临床常见的心身疾病,从形、气、神的视角出发,认为该病的发生与形质病变、气化失常、神志异常有关。“形质病变”是斑秃最突出的外在表现,脱发或被毛区的毛发损伤均可归于不同程度的“形变”,而该类“形变”的微观基础是玄府的病理变化,故“玄府形变”为斑秃发生的病理基础;“气化失常”是斑秃发生的中心环节,包括先后天脏腑虚衰和人体气机失常;神志异常古称“神不使”,贯穿于疾病的始终,是斑秃发生的关键因素。因此,斑秃的发生发展多由形、气、神三个层次的结构功能紊乱所致。本文从形气神一体观来诊疗斑秃,并依此提出急以固形、缓以治气、统以调神的治疗原则,以期为临床治疗斑秃提供又一新的思路。
