International journal of trichology. 2023;15(2):50-55
Abstract
BACKGROUND Hair graft preservation is an important factor that influences graft survival in hair transplantation. OBJECTIVE To investigate the benefits of adding platelet-rich plasma (PRP), and the effect of different storage solutions and temperatures on hair follicle preservation. MATERIALS AND METHODS This randomized-controlled study included 10 androgenetic alopecia patients who underwent hair transplantation. Forty-five hair grafts were collected from each patient and then randomized to 8 different culture conditions for 7 days. Hair grafts were cultured in Williams' Medium E or Ringer's lactate solution (RLS) at either 4°C or 37°C, and with or without 10% PRP supplementation. RESULTS In vitro hair growth in Williams' Medium E was significantly greater than in RLS. The 37°C temperature condition was found to be significantly better than the 4°C condition. The growth of hair grafts cultured with PRP was not significance difference from those without PRP. However, immunofluorescence staining for cytokeratin 15 showed greater expression in hair graft cultured with PRP. CONCLUSION PRP may have a beneficial effect for preserving the viability of hair grafts. Williams' Medium E and 37°C temperature were found to be superior to RLS and 4°C relative to hair follicle growth in organ culture.

Cureus. 2023;15(5):e38696
Abstract
Background and aim Androgenetic alopecia (AGA) is a well-known hair loss disorder in both men and women affecting approximately 80% and 50% of the population, respectively. Various treatment options for AGA are available with varying efficacy. Combination therapy is a new dictum to combat AGA. Hence, this study aimed to compare the efficacy of commonly used topical therapies such as Procapil with platelet-rich plasma (PRP) and redensyl, saw palmetto (SP), and biotin (RSB) with PRP. Materials and methods This was a randomized controlled trial conducted on 54 male patients with AGA attending the outpatient department in a tertiary care hospital. Participants were randomly assigned into two equal groups (A and B). Group A participants were treated with Procapil with PRP, and group B participants were treated with redensyl, saw palmetto, and biotin with PRP at three weeks intervals for a total period of four sessions. Clinical improvement was assessed by serial hair photography by a third blinded observer and was recorded. Results A total of 54 individuals were included and were distributed into 27 each in group A and group B. AGA grading score was found significant between the groups with P < 0.05. Conclusion PRP with adjuvants redensyl, saw palmetto, and biotin can be a better alternative to the current therapies of PRP.

Abstract
OBJECTIVE To critically assess the effect and safety of platelet-rich plasma (PRP) in chronic wounds and vitiligo. METHODS A systematic literature searching was performed. Results were expressed as weight mean difference (WMD) or risk ratio (RR) with 95% confidence intervals (CIs). Pooled estimates were performed using a fixed-effects model or random-effects model, depending on the heterogeneity among studies. RESULTS A total of 27 studies were included in this meta-analysis. In patients with chronic diabetic ulcers, PRP significantly increased proportion of complete wound healing, percentage of wound area healed, and shortened the complete wound healing. In venous ulcers, PRP improved the epithelialized area and percentage of wound area healed. In vitiligo, PRP had better results in degree of improvement and mean repigmentation than controls. Regarding the safety profile, PRP did not increase the risk of infection in patients with chronic diabetic ulcers. Meta-regression revealed that source of PRP and preparation method of PRP significantly affected the proportion of complete wound healing, whereas age, gender, country, duration of wound, and wound size had no impact on this outcome. CONCLUSION PRP is effective and safe, and can be used as a potential therapeutic adjunct or alternative treatment in chronic wounds of multiple etiologies and vitiligo.

Abstract
BACKGROUND Platelet-rich plasma (PRP) has been increasingly accepted as a potential therapy in the treatment of androgenetic alopecia (AGA), However, there remains a dearth of data on the effectiveness of PRP prepared by automatic blood cell separator with a combination of topical minoxidil for the treatment of AGA. OBJECTIVE To evaluate the efficacy and safety of PRP prepared by automatic blood cell separator combined with topical 5% minoxidil therapy in male AGA. METHODS Thirty male patients with mild/moderate AGA were enrolled in a randomized double-blind controlled study. Patients were randomly divided into two treatment arms: (group A) PRP prepared by automatic blood cell separator combined with topical 5% minoxidil group; (group B) PRP prepared by automatic blood cell separator combined with a topical placebo group. Trichoscopic assessments regarding hair density/quantity and mean hair diameter were performed at baseline and follow-up. Clinical efficacy of global photography and patient satisfaction were conducted to verify the therapeutic efficacy of the treatment, and the occurrence of adverse reactions was recorded. RESULTS We detected a significant increase in all patients in hair density and quantity after PRP treatment (p < 0.05), and there was no significant difference in mean hair diameter. Although hair density/quantity was more pronounced in group A than in group B, the difference between groups was not statistically significant (p > 0.05). In terms of clinical efficacy and patient satisfaction, group A was superior to group B, and no serious adverse reactions occurred. CONCLUSION We hereby conclude that the injections of PRP prepared by an automated method are effective and safe in the treatment of mild-to-moderate male AGA patients, and its combination with topical 5% minoxidil therapy was superior to PRP monotherapy with better clinical efficacy and higher patient satisfaction.

Abstract
BACKGROUND The efficacy and safety evaluation of the transplantation of autologous fat, platelet-rich plasma (PRP) and stromal vascular fraction (SVF) in acne scars has not been completely unified. This article will analyze and process the data of the included studies through evidence-based medicine to evaluate the efficacy and safety of autologous fat grafting, PRP and SVF for acne scar treatment, so as to provide treatment basis and strategy for the clinical treatment of acne scars. METHODS We searched the PubMed, Embase, Cochrane Library databases, CNKI, Wanfang and CQVIP databases for studies published during the time between the establishment of the databases through October 2022. We included studies that report autologous fat grafting, SVF and PRP for patients with acne scars. We excluded repeated publication, researches without full text, incomplete information or inability to conduct data extraction and animal experiments, case report, reviews and systematic reviews. STATA 15.1 software was used to analyze the data. RESULTS The findings showed that fat grafting had excellent improvement, marked improvement, moderate improvement and mild improvement rates of 36%, 27%, 18% and 18%, respectively, PRP had excellent improvement, marked improvement, moderate improvement and mild improvement rates of 0%, 26%, 47% and 25%, respectively, and the SVF had excellent improvement, marked improvement, moderate improvement and mild improvement rates of 73%, 25%, 3% and 0%, respectively. Additionally, the pooled results showed that there was no significant difference between PRP treatment and pre-treatment in Goodman and Baron scale score. However, Shetty et al. reported that Goodman and Baron scale score after fat grafting was significantly lower than pre-treatment. The results also showed that after fat grafting treatment, incidence of pain after fat grafting was 70%. After PRP treatment, in addition to pain (17%), there is a higher probability of postinflammatory hyperpigmentation (17%) and hematoma (6%). After SVF treatment, the incidence of postinflammatory hyperpigmentation and hematoma was all 0%. CONCLUSION Autologous fat grafting, PRP and SVF are effective for the treatment of acne scars, and the safety of autologous fat grafting, PRP and SVF is acceptable. Autologous fat grafting and SVF may be a better treatment for acne scars than PRP. However, this hypothesis still needs to be tested in the future large randomized controlled trials.

Journal of cutaneous medicine and surgery. 2023;:12034754231191461
Abstract
Platelet-rich plasma (PRP) contains a variety of growth factors and has been widely used in maxillofacial surgery, orthopedics, plastic surgery, ophthalmology, and other fields. In recent years, with the increasing morbidity of androgenetic alopecia (AGA), the use of PRP has also increased. The objective of this article was to evaluate the efficacy and safety of PRP for AGA. We searched PubMed, Embase, Web of Science, and Cochrane Library, covering the databases from their earliest records until March 2022. We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) to explore the effects of PRP for hair density, hair count, and hair diameter in AGA. Nine trials involving 238 patients were included. The meta-analysis showed that PRP for AGA increased hair density at 3 and 6 months with statistically significant differences compared with the placebo (P < .05). PRP also increased hair count and hair diameter compared with the baseline, but there was no significant difference compared with the placebo (P > .05). Two of the 7 studies reported adverse reactions. No serious adverse reactions were found. In conclusion, PRP is an effective and safe treatment for increasing the hair density in AGA. Trial registration: The systematic review was registered with PROSPERO (CRD42022362432).

Abstract
BACKGROUND Acne scars cause significant psychosocial stress. Despite a wide armamentarium, there is a constant search for an effective modality. Autologous injectable platelet-rich fibrin (i-PRF) is a promising novel option in the management of atrophic scars. OBJECTIVE To compare efficacy of autologous i-PRF with microneedling against microneedling alone in atrophic acne scars. MATERIALS AND METHODS A split-face prospective interventional study was conducted on 40 patients with atrophic acne scars. Autologous i-PRF and normal saline were injected into each scar on right (study) and left (control) sides, respectively, followed by microneedling on both sides. Four sessions were performed at monthly intervals with follow-up at 2 months. For assessment, Goodman and Baron (GB) scale, physician subjective score, and patient satisfaction scores were used. RESULTS Mean baseline GB grade on each side was 3.45. At 24 weeks, mean GB grade was significantly reduced on the study side (1.47, SD 0.56) than control side (3.33, SD 0.53). Mean patient satisfaction score was significantly higher on the right side (5.95) compared with the left side (5.35). Rolling scars responded the best followed by boxcar and ice-pick scars. CONCLUSION Autologous i-PRF and microneedling act synergistically to improve acne scars.

Aesthetic plastic surgery. 2023
Abstract
BACKGROUND Androgenetic alopecia (AGA) is a common yet difficult-to-treat condition, which is an important psychosocial problem. Platelet-rich plasma (PRP) therapy has been considered as a promising treatment for AGA. However, the current evidence on the efficacy of PRP for treating AGA is still controversial. This study evaluated the efficacy of PRP monotherapy in the treatment of AGA. METHODS We searched PubMed, Embase, Cochrane Library and Web of Science to collect randomized controlled trials on use of PRP in AGA for a meta-analysis. RESULTS Ten trials with a total 555 treatment units were identified. The hair density in PRP group was significantly higher than control group [MD = 25.09, 95%CI: 9.03-41.15, p = 0.002], but there was no significant difference in hair diameter between two groups [SMD = 0.57, 95%CI: - 0.23 to 1.38, p = 0.16]. Subgroup analyses indicated that hair density was significantly higher among the male-only trials than in the mixed-sex samples (p = 0.02). In addition, neither the split-head design nor the year of publication affected hair density (p = 0.05, p = 0.06). However, hair density was significantly higher in trials with a sample size less than 30 (p = 0.0004). CONCLUSIONS PRP treatment increased hair density in participants with AGA, but not hair diameter. In terms of hair density, PRP elicits stronger effects in male patients. There was a trend toward differed treatment effect by gender with PRP injection, which warrants further investigation. Especially in the case of female.

Balasundaram M, Kumari R, Ramassamy S
The Journal of dermatological treatment. 2023;:1-20
Abstract
BACKGROUND Platelet-rich plasma (PRP) is an adjunctive treatment in androgenetic alopecia (AGA). Its role as a monotherapy, when compared to FDA-approved therapies in moderate grades of androgenetic alopecia is not established. OBJECTIVES We sought to study the efficacy and safety of standardized non-activated PRP preparation against topical minoxidil in AGA. METHODS Men aged 20-50 with Grade III and IV (Modified Hamilton-Norwood) AGA were randomized to receive 5% Minoxidil (x6 months) or PRP injections (monthly x3). The primary endpoints were global photographic assessment at week 24, change in target area hair counts, density, and anagen hair at week 12. Other outcomes were subjects' satisfaction and adverse events. RESULTS In total, 64 participants were randomized. At week 24, 56% responded to Minoxidil arm and 38% to PRP (p= 0.124). There was a significant increase in target area hair count and density at week 12 within the groups. The difference between the groups was not statistically significant. Adverse events occurred in 53% and 37% of the PRP and minoxidil groups, respectively. Patient satisfaction was better with Minoxidil. CONCLUSION PRP is effective in the treatment of moderate grades of androgenetic alopecia in men, although perhaps not different from minoxidil. Side effects occur more frequently with PRP.

Journal of cosmetic dermatology. 2023
Abstract
OBJECTIVE To evaluate the efficacy of platelet-rich plasma (PRP) in the treatment of androgenetic alopecia, as well as establish an effective treatment protocol and optimal PRP preparation procedure. METHODS We searched the PubMed, Scopus, Embase, Cochrane, CNKI, and Wanfang databases from inception to October 29, 2021, using PROSPERO's International Prospective Register of Systematic Reviews (registration ID: CRD42022295921). RESULTS The original literature search revealed 215 reviews; after duplication removal, 89 papers were eliminated, 95 were eliminated after reading the titles and abstracts, and eventually, 28 articles were included after reading the complete text. CONCLUSIONS PRP treatment for androgenetic alopecia is effective, and we recommend the following: (1) a PRP volume of at least 0.05 ml/cm(2) , preferably 0.1 ml/cm(2) ; (2) at least three consecutive treatments at an interval of 1 month; (3) intensive therapy is beneficial and can be provided from 3 to 6 months after continuous treatment; (4) objective indicators such as hair diameter, hair count; (5) long-term follow-up.
