Characterization of distinct microbiota associated with androgenetic alopecia patients treated and untreated with platelet-rich plasma(PRP)

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.

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.

Psychological stress impact neurotrophic factor levels in patients with androgenetic alopecia and correlated with disease progression

BACKGROUND Androgenetic alopecia(AGA)is a common form of hair loss that can be influenced by psychological factors.AIM To investigate the impact of mental stress on neurotrophic factors in patients with AGA and correlate the findings with the progression of AGA.METHODS A total of 120 patients with AGA were analyzed in this study,which were divided into a non-stress group(n=30)and a stress group(n=90)on the basis of the presence or absence of psychological stress confirmed by Depression Anxiety Stress Scale-21 scale.The baseline demographic characteristics,serum cortisol levels,hair growth parameters,neurotrophic factors,and AGA progression scores between the non-stress and stress groups were compared.Correlation analyses were conducted to assess the relationships among stress,neurotrophic factors,hair loss progression,and AGA progression.RESULTS This study revealed significantly higher cortisol levels throughout the day in the stress group than in the non-stress group.The stress group exhibited lower levels of nerve growth factor,brain-derived neurotrophic factor,and glial cell linederived neurotrophic factor and higher expression levels of neurotrophin(NT)-3 and NT-4 than the non-stress group.Hair parameters indicated lower hair diameter,decreased hair density,and more severe AGA grading in the stress group,whereas follicle count and terminal/vellus hair ratio showed no significant differences between the two groups.After 1 year of treatment with 5%minoxidil,efficacy was observed to be lower but AGA progression was notably more pronounced in the stress group than in the non-stress group.Disease progression was positively correlated with high stress and NT-4 levels.CONCLUSION This study provides compelling evidence of the influence of mental stress on neurotrophic factors and its correlation with the progression of AGA.The findings underscore the need for a comprehensive approach to the management of AGA that considers the physiological and psychosocial aspects.Further research is warranted to validate the findings and explore targeted therapeutic interventions for individuals with stress-related AGA.

Re-Densification Effect of Pressure-Injected Peptide-Hyaluronic Acid Combination on Male Androgenic Alopecia

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. .

Serum Gelsolin Levels in PCOS-Related Androgenetic Alopecia

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.

Defective Expression of the Gap Junction Protein Pannexin-1 Channel Contributes to the Formation of PCOS-Realted Androgenetic Alopecia

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.
