Background:Androgenic alopecia(AGA)is the most common type of hair loss in men,and there are many studies on the treatment of hair loss by platelet-rich plasma(PRP).The human scalp contains a huge microbiome,but its role in the process of hair loss remains unclear,and the relationship between PRP and the microbiome needs further study.Therefore,the purpose of this study was to investigate the effect of PRP treatment on scalp microbiota composition.Methods:We performed PRP treatment on 14 patients with AGA,observed their clinical efficacy,and collected scalp swab samples before and after treatment.The scalp microflora of AGA patients before and after treatment was characterized by amplifying the V3-V4 region of the 16 s RNA gene and sequencing for bacterial identification.Results:The results showed that PRP was effective in the treatment of AGA patients,and the hair growth increased significantly.The results of relative abundance analysis of microbiota showed that after treatment,g_Cutibacterium increased and g_Staphylococcus decreased,which played a stable role in scalp microbiota.In addition,g_Lawsonella decreased,indicating that the scalp oil production decreased after treatment.Conclusions:The findings suggest that PRP may play a role in treating AGA through scalp microbiome rebalancing. 展开更多

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. 展开更多

Introduction: Mechanism of male androgenic alopecia (MAGA) is complex and leads to an excessive hair shedding and decreased hair density. Oral, topical, and injectable autologous treatments demonstrate ability to stimulate hair re-growth, but the response is suboptimal or plateaus off. Synthetic combination of the peptide complex and hyaluronic acid (P-HA) demonstrated hair regrowth in alopecia patients. Electronically-operated pneumatic injections (EPI) generate micro-trauma in the dermis and under wound-healing conditions may enhance regeneration effect of P-HA. Methods: Subjects seeking improvement of their male pattern hair loss (Hamilton-Norwood type 2-4) received the P-HA treatments through EPI. The course included 4 treatments every two weeks over the 8-week period. In 6 months, the hair growth was assessed comparative to baseline by global clinical photography and digital phototrichograms. The treatment safety and tolerability were documented through the whole study period. Results: Twelve men (30-45 years old) completed the treatment course with high tolerability and without adverse events. Post-treatment assessment of the previously bald areas showed improved coverage on the clinical photographs. The phototrichograms demonstrated statistically significant increase in terminal hair density by 36%, cumulative hair thickness by 37%, and follicular units by 20%;all contributing to a 38% increase in cumulated hair density (all p Conclusion: Electronic pneumatic injections are well tolerated and can be safely used for the needle-free administration of the peptide-hyaluronic acid combination in MAGA therapy. We achieved significant hair re-densification in the balding scalp. The exact role of the EPI-induced impact in the hair re-growth mechanism remains to be ascertained. . 展开更多

Aim: To compare serum gelsolin levels of women with androgenetic alopecia with PCOS and patients with non-PCOS alopecia. Materials and Methods: A total of 30 PCOS patients who applied to our dermatology clinic with the complaint of hair loss and were diagnosed with androgenetic alopecia (AGA) were included in the study. Thirty patients who were not diagnosed with PCOS but were diagnosed with AGA were considered as the control group. Patients in the control group were matched with PCOS in terms of age. AGA was diagnosed in cases of widespread thinning of the hair on the scalp and preservation of the frontal hairline. All participants underwent a complete clinical examination and blood examination. Serum gelsolin levels of both groups were measured by ELISA. Results: The number, age, and BMI values of the participants in both groups were recorded as similar. Serum total testosterone, insulin, HOMA-IR and LH values were significantly higher in the PCOS with AGA compared to the AGA without PCOS. There is no significant difference between groups in terms of serum FSH levels. Serum gelsolin levels of the PCOS group were significantly lower than the control group (160.1 ± 34.2 ng/mL vs. 188.6 ± 46.7 ng/mL, p Conclusions: Serum gelsolin levels in PCOS patients with androgenetic alopecia were found to be significantly lower than in non-PCOS alopecia patient groups. 展开更多

Objective: To determine serum pannexin-1 channel levels and their association with hair loss in women with PCOS diagnosed with female androgenetic alopecia (FAGA). Materials and Methods: Thirty-five women with PCOS who presented with diffuse and treatment-resistant progressive hair loss and were diagnosed with FAGA were included in the study. 25 patients who were diagnosed with female androgenetic alopecia but did not have PCOS were considered as the control group. PCOS and control groups were matched by age. Follicular miniaturization, displacement of terminal hairs with vellus hairs, and a diffuse decrease in hair density were accepted as FAGA in the trcihoscopy examination of the vertex and bitempoaral area. On the third day of the menstrual cycle serum FSH, LH, testosterone, PRL and insulin levels were measured. Insulin resistance was calculated with HOMA-IR. Serum pannexin-1 channel levels of each group were mesured with ELISA. Results: Serum pannexin 1 channels levels of FAGA group due to PCOS were found to be significantly higher than FAGA patients in the control group (2.72 ± 1.09 ng/mL vs 1.65 ± 0.97 ng/mL, p < 0.01). Serum LH, insulin and testosterone levels of PCOS group were significantly higher than controls. HOMA-IR values were significantly higher and >2.5 in the PCOS group compared to the controls. PRL values were similar except for one patient with elevated PRL. Serum FSH values were the same in both groups. A positive and significant correlation was found between pannexin 1 channels levels and HOMA-IR and serum testosterone levels (r = 0.650, p Conclusions: In addition to hyperandrogenemia, increased pannexin 1 channel levels may play a role in the etiology of PCOS associated FAGA, as it impairs the communication between the skin and hair follicle. 展开更多

BACKGROUND Alopecia areata(AA)is an inflammatory disease with autoimmune,environmental,and inherited components directed at the hair follicle,either limited to patchy hair loss over the scalp(Focalis,AF),total loss of scalp hair(Totalis,AT),or total loss of both scalp and body hair(Universalis,AU).Despite multiple treatment modalities,no therapy exists.Vitamin D deficiency in patients with AA/AT/AF influences disease severity and duration,inversely correlating with inflammation histologically.CASE SUMMARY Three girls presented with AT(P1),AU(P2),and AF(P3)at the ages of 1,5,and 5 years,respectively.For P1-P2,all available treatments implemented for 2 years had failed.We started an initial 6-mo repletion with oral cholecalciferol 2000/4000 IU/d,with no apparent effect.Then we attempted immunomodulation using oral calcitriol and its analog paricalcitol.On calcitriol,0.5 mcg/d P1 regrew hair within 6 mo.After 4 years,a relapse with loss of eyebrow hair was resolved after doubling the calcitriol dose to 0.5 mcg×2/d;the results have been maintained for 6 years to date.On calcitriol,0.25 mcg×3/d P2 led to the development of asymptomatic hypercalcemia-hypercalciuria,which was immediately resolved by switching to paricalcitol 2 mcg×3/d;mild tolerable hypercalciuria was maintained.Hair regrowth was observed at 6 mo,stabilizing only as fur at 12 mo.AF in P3 was resolved completely within 3 mo on a daily high dose(8000 IU)of cholecalciferol.CONCLUSION Vitamin D may have immunomodulating therapeutic impact on AT/AU/AF,which needs to be explored with further pilot clinical trials. 展开更多

Syphilitic alopecia (SA) is a rare skin manifestation in secondary syphilis and sometimes indistinguishable from other alopecia. SA is of 2 types, symptomatic and essential, and 3 clinical types, moth-eaten or patchy pattern, diffuse pattern and a combination of both. SA in our case indicated symptomatic SA with moth-eaten hairloss. A 46-year-old Japanese homosexual man experienced hairloss followed by the pruritic skin rash. Physical examination of the scalp showed diffusely spread papulosquamous erythema and incomplete hairloss around the lesions. The scalp lesions appeared as “moth-eaten alopecia”. Serological examination for syphilis and HIV were positive. Thus, SA complicated with HIV infection was diagnosed. He was treated with a single perioral dose of ampicillin for 4 weeks, then his condition improved rapidly and hair regrowth occurred. HIV-infected persons show a high incidence of syphilis. Therefore, HIV test should be considered for patients with alopecia. 展开更多

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. 展开更多

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. 展开更多

Qigong is a part of traditional Chinese medicine. According to the antique treaties, the foundations of traditional Chinese medicine are based in maintaining the harmony between Qi (energy), Jing (essence) and Shen (spirit). Alterations in this harmony can develop and determine the appearance of disease. Therapeutic effects of Qigong are helpful in the prevention and treatment of several diseases. It's main role in restoring body functions is due to the communication between internal organs, tissues and cells. The main goal of this work is to show the efficacy of Qigong in the treatment of a dermatological disease characterized by the appearance of circular or oval patches of missing hair, known as alopecia universalis. For western medicine the exact cause of this illness is not totally revealed, however, it's attributed to psycological, genetics and metabolic alterations. From the traditional Chinese medicine perspective, hair alterations are framed in the area of the water energy, represented by the kidney organ. The results of Qigong treatment suggested that the cranial hair follicles had been activated since the first treatment. As treatment progressed, the cranial hair follicles continued to grow, what's more, the brightness and pigmentation of the hair also increased. Therefore, in the clinical conditions evaluated, Qigong could be an effective alternative treatment in consideration of the visible evidence about rapid and long lasting results. Besides, we did not observe any side effects of Qigong in this case. 展开更多

Development of Dermal cell line has great scope in the field of skin related diseases and regenerative medicine. Alopecia leads to a skin disorder causing balding and its mechanism is not yet understood. In the present study, we have developed and characterized a heterogeneous population of human dermal mesenchymal-like stem cell line from scalp biopsy of androgenetic alopecia patient with a view to isolate cells from the bulge region of the hair follicle. Our study showed that the dermal cells isolated from dermis of skin showed epithelial-like cells expressing CD34 and Keratin 18, which are characteristic of bulge hair follicle cells. These cells also expressed mesenchymal phenotypes and pluripotency markers such as Oct4, Nanog and SOX2. These cells were designated as “Human Dermal Mesenchymal-like Stem Cells (hDMSCs)”. To confirm their epithelial phenotypes, we have grown these cells at low serum concentration and it was observed that 3% serum concentration provided optimum conditions for their growth and maintenance of characteristics. The hDMSCs cells are presently at passage 10. This study reports the establishment of human dermal mesenchymal-like cell line from the dermis of Alopecia patient, which may be used as an in vitro model system to study the mechanism of Alopecia and other related skin disorders. 展开更多

Studies have shown that platelet concentrates can induce the proliferation of the dermal papilla and the vascularization of the perifollicular tissue, as well as accelerate the telogen-to-anagen transition, thereby promoting the regrowth of hair improving the appearance of hair loss. Herein, we report on the application of a new, modified form of platelet concentrates, namely, concentrated growth factors (CGFs), in 15 cases of androgenetic alopecia (AGA). 15 cases of androgenetic alopecia were treated with the use of monthly, subcutaneous injections of autologous CGF in the scalp. A total of 3 injections were administered 4 weeks apart, and the patients were followed up for 6 months. Assessments were performed before the treatments and at 4, 8, 12 and 24 weeks after the first treatment. The treatment outcomes were assessed by taking macroscopic photographs and trichoscopic photomicrographs, as well as by using the Global Aesthetic Improvement Scale (GAIS) and the patient satisfaction survey. In order to determine the safety of the treatment, the injection area was observed for signs of infection or mass evaluation. The photographs showed significant improvement in hair appearance after injections of CGF. The hair photomicrographs showed that CGF promoted the regrowth of hair in balding areas, with an increased hair density and an increased ratio of terminal to vellus hair. The GAIS suggested that CGF treatments were effective in treating AGA, and the majority of patients were satisfied with their improvement. In addition, treatments resulted in a faster rate of hair growth and a decrease in the greasy and unpleasant sensation of the hair of the patients. At the last visit, none of the 15 patients reported experiencing side-effects during the follow-up period. To conclude, the application of CGF can be an effective method in the treatment of androgenetic alopecia. 展开更多

Frontal fibrosing alopecia(FFA) is a recently described form of primary cicatricial alopecia, characterized by progressive recession of the frontotemporal hairline and eyebrow loss, occurring predominantly in postmenopausal women. The incidence of FFA has increased significantly during the last decade and we may be facing an epidemic of the disease. Because this condition causes permanent hair loss, prompt diagnosis and treatment are essential for obtaining optimal outcome. This article reviews existing knowledge on epidemiology, etiopathogenesis, clinico-histological features, diagnosis,and treatment modalities of FFA. 展开更多

Background: Scarring alopecia like discoid lupus erythematosus, lichenplanopilaris and scarring folliculitis are common skin problems where differentiations between them are often difficult in many cases. Objective: To report, study and evaluate cases of lichen planopilaris and characterize the different clinical points in favor of this disease. Patients and Methods: This case series descriptive study was done at Department of Dermatology-Baghdad Teaching Hospital from January 2010 to November 2012. Sixty seven patients were included where histological and dermatological examinations were carried out to all patients regarding all relevant points related to the disease. Punch biopsies were performed from ten patients for histopathological study. Results: The mean age of onset of the disease was 36.7 ± 5 years with a mean duration of the disease being 4.4 ± 3 years. The male to female ratio was 1.4:1. The characteristic lesions were pigmented scarring moth eaten alopecia surrounded by pigmented hyperkeratotic follicular papules involving mainly the fronto-vertical and parietal scalp. Conclusions: Lichen planopilaris is a common cause of scalp scarring alopecia in adult and it has many characteristic clinical features which can facilitate differentiation from other pathologic scalp conditions like discoid lupus erythematosus. 展开更多

Background: Progressing androgenetic alopecia (AGA), in both sexes, can result in severe distress. Treatments with the capacity to slow down the progression of AGA, or even to bring it to a halt, and at the same time don’t come with side effects are consequently highly sought for. Therefore this study investigates the effect of an over-the-counter nutritional supplement and a similarly formulated topical hair lotion on the progression of AGA. Methods: Seventy-nine healthy study participants of both sexes, who were diagnosed with AGA were divided into 4 study groups. The subjects of the first group were treated with the nutritional supplement, the subjects of the second group with the topical hair lotion, the subjects of the third group with both products, and the subjects of the fourth group served as a no-treatment control. At the beginning and at the end of this nine-month study, the participants were evaluated for their hair loss status. They also answered a questionnaire for self-assessment. A part of the subjects from each study group were further analysed by phototrichography, in order to measure the number of anagen and telogen hairs. Results: It turned out that the supplement, the lotion as well as the treatment with both products not only lead to a reduction in hair loss but also to an increased anagen to telogen hair ratio, whereas no such effects could be measured for the control group. Conclusion: The results show that a systemic delivery via a nutritional supplement, as well as a follicular delivery via a topically applied lotion, both resulted in a reduced hair loss rate as well as in an increased anagen to telogen hair ratio. This demonstrates that the tested formulation is effectively slowing down the progression of AGA. 展开更多
