Journal of cosmetic dermatology. 2024
Abstract
BACKGROUND Androgenetic alopecia (AGA), also referred to as male or female pattern hair loss, is the commonest cause of chronic hair loss and affects up to 80% of men by the age of 70. Despite a high prevalence, there are few approved therapies, which show minimal efficacy. OBJECTIVES This systematic review aims to evaluate the efficacy of platelet-rich plasma (PrP) in the treatment of AGA in male patients. METHODS MEDLINE, EMBASE, Cochrane (CENTRAL), CINAHL, clinicaltrials.gov, Google Scholar and the Science Citation Index database were searched to identify eligible studies. All randomized controlled trials (RCTs) and prospective cohort studies related to PrP use in AGA were included. Primary outcomes included changes in hair density and hair count. Methodological quality was assessed using bias assessment tools. RESULTS Eight RCTs and one cohort study were included in the review with a total of 291 participants. Six studies reported a statistically significant increase in hair density in the PrP group versus the control. Five studies reported a statistically significant increase in hair count with PrP. Seven studies showed moderate risk and two showed low risk of bias. CONCLUSION In a methodologically robust review on the effectiveness of PrP on male AGA, PrP demonstrated some potential to be used therapeutically. However, the low quality of evidence, moderate risk of bias, and high heterogeneity of included studies limit inferences and call for more robust designs to investigate this further.

Photodermatology, photoimmunology & photomedicine. 2024;40(1):e12944
Abstract
BACKGROUND Several treatment modalities are available for the treatment of vitiligo due to the lack of a uniformly effective therapy. Topical latanoprost 0.005% is an effective topical treatment. Fractional CO(2) laser alone or combined with platelet-rich plasma (PRP) has been proposed as effective adjunctive therapies. OBJECTIVES We aimed to compare the efficacy of topical latanoprost 0.005% (Ioprost®, Orchidia, Egypt) combined with either add-on fractional CO(2) laser or fractional CO(2) -PRP versus topical latanoprost monotherapy in the treatment of localized stable vitiligo. PATIENTS/METHODS The study included 60 patients randomly assigned into three equal groups. Group A patients received topical latanoprost drops only. Group B patients received topical latanoprost drops and fractional CO(2) laser sessions at 2-week interval for 3 months. Group C patients received topical latanoprost drops and fractional CO(2) laser sessions combined with PRP at a 2-week interval for 3 months. The mean improvement score by the physician was calculated 4 months after the start of the study. Punch skin biopsies were obtained before treatment and 4 months from the beginning of the study and stained with H&E and HMB-45 antibody for evaluation of pigmentation. RESULTS Significant clinical improvement of vitiligo lesions with significant increase of re-pigmentation were reported in the three treated groups. Latanoprost in combination with fractional CO(2) and PRP was associated with more significant therapeutic outcomes than either combined latanoprost and fractional CO(2) or latanoprost alone. CONCLUSION Fractional CO(2) laser-PRP enhances the therapeutic efficacy of latanoprost 0.005% in the treatment of localized stable vitiligo.

Abstract
BACKGROUND As the demand for non-invasive esthetic procedures to maintain a youthful appearance increases, there has been growing interest in the use of autologous platelet-rich plasma (PRP) and platelet-poor plasma (PPP) for the treatment of facial aging. However, there are few studies directly comparing the efficacy of PRP and PPP for facial rejuvenation. OBJECTIVES This study aimed to compare the efficacy of PRP and PPP for facial rejuvenation. METHODS This single-center, double-blind, randomized controlled trial was conducted from January 1, 2022, to July 31, 2022, and included ten participants who completed the follow-up. The participants were randomly assigned to receive 2.5-mL injections of PRP and PPP on different sides of the face in three sessions with 1-month intervals. The outcome was primarily determined by blinded photographic assessments and secondly by scores of the VISIA® system during the follow-up. RESULTS Both PRP and PPP treatments resulted in significant improvement in the Global Aesthetic Improvement Scales and Modified Fitzpatrick Wrinkle Scale for periocular Powered by Editorial Manager® and ProduXion Manager® from Aries Systems Corporation wrinkles, with no significant difference between the two groups. However, no improvement was observed in the Wrinkle Severity Rating Scales for nasolabial folds in either the PRP- or PPP-treated groups. Furthermore, no severe adverse events were reported. CONCLUSIONS Both PRP and PPP are effective in treating facial photoaging. PRP exhibited slightly superior efficacy in enhancing overall skin condition, while PPP was slightly more effective in improving shallow wrinkles. This study provides valuable evidence for the use of PRP and PPP in facial rejuvenation procedures.

Jin, F., Li, X., Chen, J., Liu, J., Wang, Y.
Journal of plastic, reconstructive & aesthetic surgery : JPRAS. 2024;90:305-314
Abstract
BACKGROUND NA OBJECTIVE Evaluate the safety and feasibility of platelet-rich plasma (PRP) in the treatment of giant congenital melanocytic nevi (GCMN) in children with human acellular dermal matrix (HADM) transplantation. PATIENTS AND METHODS A total of 22 children with GCMN were included in the study. They were divided into an experimental and a control group. The experimental group used the method of HADM with Razor Autologous Skin Graft combined with PRP to repair skin and soft tissue defects after giant nevus resection (Group A, n = 11). The control group was treated with HADM with Razor Autologous Skin Graft (Group B, n = 11) only. To compare the survival rate of skin grafts, we used the Vancouver Scar Scale (VSS) for the postoperative skin graft area and the Patient and Observer Scar Assessment Scale (POSAS) to compare the two groups of patients. RESULTS There was no statistically significant difference in age, gender, location of giant nevi, and pathological classification between Group A and Group (P > 0.05). The survival rate of skin grafting and the VSS and POSAS scores of scar tissue in group A were superior to those of group B (P < 0.05). CONCLUSIONS PRP has improved the survival rate of composite skin grafting in children with GCMN, and long-term satisfactory prognosis of scar healing. Therefore, we consider this treatment method a valuable contribution to clinical practice.

Kaiser, M. A., Ferrari, L. M., Gaumond, S. I., Issa, N., Jimenez, J. J., Issa, N. T.
Journal of cutaneous and aesthetic surgery. 2023;16(3):169-177
Abstract
Androgenetic alopecia (AGA) is the most common cause of alopecia in males and females. Minoxidil and finasteride are the only FDA-approved treatments for AGA. New treatments including Platelet Rich Plasma (PRP) and microneedling have shown promising results. The purpose of this literature review was to highlight recent studies examining the effects of topical minoxidil combined with PRP to minoxidil or PRP monotherapy. The method used for this paper includes a systematic review of the literature from 2010 to 2022 using the PubMed, EMBASE, and MEDLINE databases examining studies evaluating combination therapies for AGA. Three randomized control trials compared combination PRP + topical 5% minoxidil to either no treatment, 5% minoxidil, or PRP only. Two studies found increased hair growth at five months and at six months following combined therapy. Another study found an increase in hair density and improved patient satisfaction with combination therapy compared to monotherapy. A prospective study revealed that patients treated with combined 5% minoxidil, PRP, and microneedling reported the highest patient and physician satisfaction compared to minoxidil monotherapy. An observational study evaluating topical 5% minoxidil with PRP reported an increase in hair diameter after one year of combination treatment compared to minoxidil monotherapy. PRP therapy combined with minoxidil and microneedling in a retrospective study was shown to increase hair growth compared to PRP with minoxidil as well as PRP or minoxidil monotherapy. In conclusion, a variety of studies demonstrated superior treatment response with a combination of PRP and minoxidil therapy in patients with AGA. Limitations to this study include different PRP preparation protocols, few randomized control studies, and small sample sizes.

Fawzy, M., Al-Mokadem, S., Alshereef, M., Elkholy, B.
Photodermatology, photoimmunology & photomedicine. 2023
Abstract
BACKGROUND Narrowband ultraviolet B (NB-UVB) phototherapy is the cornerstone of vitiligo treatment. Its combination with other treatments usually yields a better response. Latanoprost, a prostaglandin F2α analog, and autologous platelet-rich plasma (PRP) have been reported to be effective for vitiligo. AIM: To evaluate the efficacy of NB-UVB combined with intralesional latanoprost or PRP for stable nonsegmental vitiligo (NSV). METHODS Sixty patients with stable NSV were recruited and randomly allocated to two equal groups. NB-UVB phototherapy was administered twice a week for all patients. Additionally, group A received intralesional latanoprost injections once weekly, while group B received intralesional autologous PRP injections every 2 weeks. RESULTS At 24 weeks, excellent repigmentation response was observed in 26.7% and 13.3% of patients in the latanoprost/NB-UVB and PRP/NB-UVB groups, respectively, with no significant difference in degrees of repigmentation between the two groups. However, the Vitiligo Extent Score for a Target Area (VESTA) score was significantly higher in the latanoprost/NB-UVB group (p = .032). Moreover, lesions located on nonacral skin responded significantly better than those on acral skin. Only erythema was significantly higher in the PRP/NB-UVB group, while the recurrence of depigmentation was significantly higher in the latanoprost/NB-UVB group. CONCLUSIONS Both latanoprost and PRP have the potential to be effective add-on therapies to NB-UVB phototherapy for stable NSV, with latanoprost resulting in a greater repigmentation response and PRP producing a more stable response.

Jafarzadeh, A., PourMohammad, A., Goodarzi, A.
International wound journal. 2023
Abstract
The primary objective of this study is to examine the efficiency of various regenerative medicine approaches, such as platelet-rich plasma, cell therapy, stromal vascular fraction, exosomes and stem cell-conditioned medium, in the process of healing hypertrophic and keloid scars. Major databases including PubMed, Scopus and Web of Science were systematically searched, and based on the content of the articles and the inclusion and exclusion criteria, eight articles were selected. Out of these eight articles, there were two non-randomized clinical trial studies (25%), one randomized, single-blinded comparative study (12.5%), one retrospective clinical observational study (12.5%) and four randomized clinical trial studies (50%). We employed EndNote X8 and Google Sheets to conduct article reviews and extract relevant data. Following the review phase, the studies underwent analysis and categorization. In all eight reviewed studies, the effectiveness of regenerative medicine in treating hypertrophic scars and keloids has been proven. Out of these studies, five (62.5%) focused on the effectiveness of platelet-rich plasma, two study (25%) examined the effectiveness of stromal vascular fraction and one study (12.5%) explored the efficacy of stem cell-conditioned medium. In two studies (25%), the treatment methods were added to standard treatment, while in six studies (75%), regenerative medicine was used as the sole treatment method and compared with standard treatment. The use of these treatment methods did not result in any serious side effects for the patients. Regenerative medicine is an effective method with minimal side effects for the treatment of hypertrophic scars and keloids. It can be used as a monotherapy or in combination with other treatment methods. However, further studies are needed to thoroughly evaluate the effectiveness of all sub-branches of this method.

Dermatologic surgery : official publication for American Society for Dermatologic Surgery [et al.]. 2023
Abstract
BACKGROUND Treating infraorbital dark circles is one of the commonest aesthetic demands worldwide. Autologous fat transfer is commonly used to treat dark circles by filling the grooves, without effect on skin quality. Platelet-rich plasma has been reported to improve skin quality. Autologous fat can be emulsified and filtered to produce nanofat, which is then injected superficially in the dark circles to improve skin quality and discoloration. OBJECTIVE To compare the efficacy of platelet-rich plasma versus combined fat transfer and nanofat in treating infraorbital dark circles. MATERIALS AND METHODS 30 patients with infraorbital dark circles of combined etiological factors were randomized into 2 equal groups: Group A treated with platelet-rich plasma and Group B treated with autologous fat transfer with emulsified fat injection. RESULTS Excellent and moderate responses were observed in 3 (20%) and 2 (13%) patients in group A versus 7 (46.7%) and 4 (27%) in group B, respectively. Nonresponders were 8 (53.3%) in group A and only 1 patient (6.7%) in group B. The difference was statistically significant regarding improvement (p = .048) and patient satisfaction (p = .032). CONCLUSION Autologous fat transfer with nanofat is significantly superior to platelet-rich plasma in improvement and satisfaction.

Platelet rich plasma use for treatment of acne scars: an overview of systematic reviews
Cruciani, M., Masiello, F., Pati, I., Pupella, S., De Angelis, V.
Blood transfusion = Trasfusione del sangue. 2023
Abstract
BACKGROUND A reappraisal of the conclusions of systematic reviews (SRs) and meta-analyses validity related to Platelet-rich plasma (PRP), alone or in combination with other treatments, compared to regimens PRP-free for the treatment of acne scars. MATERIALS AND METHODS An overview of SRs. The methodological quality of the reviews was assessed using AMSTAR-2 checklist; quality of the evidence of primary studies was appraised following the GRADE approach. RESULTS Fifteen SRs were included in this overview. Data were from 124 overlapping reports, based on 34 individual primary studies (10 parallel arm randomized trials, 21 split-face studies, and 3 uncontrolled studies). Most of the studies evaluated combination of PRP with microneedling or with laser therapy compared to microneedling or laser therapy without PRP. Clinical improvement (reported as degree of improvement or improvement score) and patient's satisfaction rate were significantly higher in PRP recipients compared to controls. Crusting time and duration of erythema were significantly shorter in PRP recipients compared to controls. Most of the reviews considered in this overview can be considered of low methodological quality due to the fact that several critical methodological requirements of AMSTAR-2 checklist were unmet or partially met; only 6 of the 15 reviews incorporated study quality in their conclusions, and no GRADE assessment was performed for the reported outcomes in any of the SRs. With the GRADE approach, the quality of the evidence for the outcomes analysed ranged from very low to low due to risk of bias in the primary studies, inconsistency between the studies, and imprecision. DISCUSSION The low or very low certainty of evidence does not support clear clinical decision about the PRP use in combination with microneedling or laser therapy for the treatment of acne scars. Further well-designed studies are required to improve the evidence base for PRP combination therapy for acne scars.

Thuangtong, R., Chaweekulrat, P., Thanomkitti, K., Triwongwaranat, D., Rujitharanawong, C.
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.
