Effectiveness of Autologous Platelet Concentrates in the Sinus Lift Surgery: Findings from Systematic Reviews and Meta-Analyses. Dent J (Basel) 2024; 12:101. [PMID: 38668013 PMCID: PMC11049363 DOI: 10.3390/dj12040101] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Revised: 03/20/2024] [Accepted: 04/08/2024] [Indexed: 04/28/2024] Open
Abstract
Maxillary sinus augmentation is one of the most predictable procedures for the rehabilitation of the posterior maxilla. The current overview aimed to summarize the findings provided by systematic reviews (SRs) and meta-analyses on the effectiveness of autologous platelet concentrates (APCs) in sinus lift and to assess the methodological quality of the included SRs. Three electronic databases have been explored. SRs and meta-analyses addressing the effectiveness of APCs in sinus lift technique were included. Clinical, radiographic and histomorphometric findings were considered for APCs as solely grafting materials and APCs in combination with biomaterials. Outcomes were implant survival rate (ISR), implant stability (IS), implant failure (IF), postoperative complications, histomorphometric findings, radiographic bone gain, bone volume and bone density. The methodological quality of the included SRs was assessed using the updated version of "A Measurement Tool to Assess Systematic Review" (AMSTAR-2). Thirty SRs were included. The methodological quality of the included reviews ranged from critically low (3 studies) to high (9 studies). The included SRs showed favorable clinical outcomes, short-term new bone formation and no biological complications when APCs were used both as solely graft material or in combination with other biomaterials. However, no significant additional effects in the long-term period were observed. APCs did not add any further positive effects compared to the physiological healing derived by the natural blood clot. The current overview of SRs highlighted the need for high-quality SRs evaluating the role of APCs in sinus lift though network meta-analyses, in order to identify the most powerful material for sinus lift augmentation. The use of APCs improves the healing of soft tissues and the postoperative quality of life in the short-term period. Thus, its application can be recommended.

Autologous platelet rich plasma (A-PRP) combined with pelvic floor muscle training for the treatment of female stress urinary incontinence (SUI): A randomized control clinical trial. Neurourol Urodyn 2024; 43:342-353. [PMID: 38108468 DOI: 10.1002/nau.25365] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Revised: 11/26/2023] [Accepted: 12/01/2023] [Indexed: 12/19/2023]
Abstract
IMPORTANCE Autologous platelet-rich plasma (A-PRP) injection is a novel intervention for stress urinary incontinence (SUI) in women. However, no Phase II clinical trial has compared the outcomes of A-PRP injection combined with pelvic floor muscle training (PFMT) with those of PFMT alone in these women. OBJECTIVE The primary aim was to compare the efficacy of A-PRP + PFMT versus PFMT alone in women with SUI. The secondary aim was to determine any adverse effects of A-PRP injection. DESIGN Randomized clinical trial, single-blind assessment. SETTING Urogynecology clinic at a tertiary medical center. PARTICIPANTS Women with previously untreated SUI. Women in whom there was any suspicion of urgency, those with an Overactive Bladder Symptoms Score of ≥1, and those with obesity, pelvic organ prolapse, thrombocytopenia, or coagulopathy were excluded. INTERVENTIONS Two injections of A-PRP were administered with a 1-month interval between injections in the A-PRP injection + PFMT group. Both groups received PFMT. MAIN OUTCOMES AND MEASURES The primary outcome was determined using the 1-h pad weight test (PWT). Secondary outcomes were measured using the Incontinence Quality of Life Questionnaire, item 11 on the International Consultation on Incontinence Questionnaire-Female Lower Urinary Tract Symptoms questionnaire, Patient Global Impression of Improvement, and the percentage subjective improvement score. RESULTS Data for 60 study participants were available for analysis (A-PRP + PFMT group, n = 31; PFMT group, n = 29). The 1-h PWT decreased significantly in the A-PRP + PFMT group but only slightly in the PFMT group at the 5-month follow-up. There was a statistically significant between-group difference in the 1-h pad weight of about 8 g in favor of the A-PRP + PFMT group. A statistically significant difference in symptoms of SUI measured by the questionnaires was found between the A-PRP + PFMT group and the PFMT group at the 2- and 5-month follow-up assessments. There were no reports of adverse events following injection of A-PRP. CONCLUSIONS AND RELEVANCE A-PRP + PFMT could be a treatment option for women with SUI. Large Phase III randomized controlled trials are required to confirm our findings.

Abstract
Clitoral reconstruction after female genital mutilation/cutting (FGM/C) is associated with significant post-operative pain and months-long recovery. Autologous platelet-rich plasma (A-PRP) reduces the time of healing and pain in orthopedic and burn patients and could also do so in clitoral reconstruction. In the present case, a 35-year-old Guinean woman who had undergone FGM/C Type IIb presented to our clinic for clitoral reconstruction. Her request was motivated by low sexual satisfaction and body image. We surgically reconstructed the clitoris using the Foldès method and applied plasma and glue of A-PRP. The patient was highly satisfied with the procedure. Two months post-operatively, her pain had ceased entirely and re-epithelialization was complete. We conclude that A-PRP may improve pain and healing after clitoral reconstruction. Extensive studies investigating long-term outcomes are needed.

Abstract
OBJECTIVE The aim of the present study was to evaluate the effect of autologous platelet-rich plasma (PRP) on wound healing and pain perception after cesarean section in high-risk patients. DESIGN This was a prospective randomized controlled trial. Participants/Materials, Settings, and Methods: This was a randomized controlled trial of 200 patients who came to the outpatient clinic of Menoufia University Hospital for elective cesarean surgery. The women were randomly assigned to 2 equal groups. The intervention group received PRP subcutaneous injection in the wound after surgery; however, the control group received the usual care. Outcome variables included the redness, edema, ecchymosis, discharge, approximation (REEDA) scale, Vancouver scar scale (VSS), and in addition to the visual analog scale (VAS). RESULTS From April 2018 to July 2020, the PRP group showed a greater reduction in the REEDA score compared to the control group on day 1, day 7, and this was continued till 6 months (1.51 ± 0.90 vs. 2.49 ± 1.12, p < 0.001). Compared with the control group, the PRP group had a significantly greater reduction in the VSS and VAS scores beginning on the seventh day (3.71 ± 0.99 vs. 4.67 ± 1.25, p < 0.001) and (5.06 ± 1.10 vs. 6.02 ± 1.15, p < 0.001), respectively, and continued till 6 months. LIMITATIONS Pain was not measured by the use of analgesics, and we did not investigate the effects of varying platelet concentrations, centrifuge duration, or speed. CONCLUSIONS PRP has positive effects on wound healing and pain reduction in high-risk patients undergoing cesarean section in low-resource settings.

Abstract
BACKGROUND Despite the increased popularity of platelet-rich plasma (PRP) in plastic surgery, there is no detailed analysis on the level of evidence on PRP use in plastic surgery. As the number of applications of PRP in plastic surgery increases, it is important for plastic surgeons to understand the scientific and validated evidence behind its use. Therefore, we performed a literature review to identify current level of evidence on platelet-rich plasma in plastic surgery. METHODS We performed a computerized search of platelet-rich plasma in plastic surgery using the MEDLINE, Cochran Library, and EMBASE databases. Data regarding the type of study, PRP application, and outcomes were collected. Then, the level of evidence was assigned using the American Society of Plastic Surgeons Level of Evidence Rating. RESULTS Our search identified 105 articles, and about 78.1% of studies were lower-quality studies: 37 level-III articles (35.2%), 32 level-IV articles (30.5%), and 13 level-V articles (12.4%). There were only 6 level-I articles and 17 level-II studies. Level-I studies were on facial rejuvenation using a laser, carpal tunnel release, cleft lip repair, trauma wounds, breast reconstruction using latissimus dorsi, and hair regrowth. CONCLUSIONS Our review of the literature shows that the level of evidence on PRP use in plastic surgery is low (21.9%). Nevertheless, we believe level-III to level-V studies are still valuable, as performing high-level quality studies in plastic surgery is difficult due to variability in surgical techniques, experiences, and materials.

Abstract
Background Corneal refractive surgeries cause epithelial damage and induce wound healing processes. To promote wound healing after photorefractive keratectomy, the effectiveness of an autologous platelet tissue graft was assessed. Case presentation A 45-year-old Asian male with low myopia and/or myopic astigmatism received photorefractive keratectomy in both eyes. The right eye was postoperatively treated with an autologous platelet tissue graft using the GPS III Platelet Concentration System to prepare platelet-rich plasma, while the left eye was not treated. Both eyes achieved the expected uncorrected distance visual acuity, but the platelet-rich-plasma-treated right eye obtained improved visual acuity more than 1 week before the untreated left eye. Perceived pain after photorefractive keratectomy was much lower and of shorter duration in the treated right eye than it was for the left eye. Pericorneal injection on the bulbar conjunctiva with superficial keratitis resolved earlier in the right eye than the left eye. Conclusions Autologous platelet tissue grafting using a GPS III to obtain platelet-rich plasma was effective in promoting corneal wound healing after photorefractive keratectomy. Thus, platelet-rich plasma may be beneficial for patients undergoing corneal refractive surgeries.

Abstract
The study aims to evaluate the effectiveness of local injection of autologous platelet rich plasma (A-PRP) as a treatment for women suffering from stress urinary incontinence (SUI). In a prospective intervention study, twenty consecutive women suffering from SUI were treated with A-PRP injection at anterior vaginal wall where mid-urethra locates. Self-reported questionnaires were used to measure pre-treatment, 1 month and 6 months post-treatment symptom severity. Secondary outcomes of sexual function and treatment effect sorted by age were analyzed with valid statistical methods. A-PRP is effective in relieving SUI symptoms at both 1 month and 6 months post-treatment without significant adverse reactions reported. It seems to have a trend that treatment success rate with cured and improved symptoms was slightly higher in the younger group, although it did not reach statistical significance (P = 0.07). No significant changes in sexual function before and after the treatment were reported by the patients. This pilot study is the first to report A-PRP treatment effect for SUI in women. The result suggested that A-PRP is a considerable treatment option for mild to moderate SUI cases. It also opens up further research opportunities for A-PRP’s clinical applications.

Abstract
Purpose: Despite high success rates in the treatment of urinary incontinence, complications related to the use of polypropylene (PP) meshes are still a concern, especially in vaginal prolapses surgeries. The objective of this study was to assess the effect of autologous platelet-rich plasma (PRP) coating on the integration of PP meshes implanted in the vaginal submucosa of rabbits. Materials and Methods: Thirty adult New Zealand rabbits were randomly divided into two groups (n=15): PP, implanted with conventional PP meshes; and PRP, implanted with autologous PRP coated PP meshes. Animals in both groups (n=5) were euthanized at 7, 30 and 90 days postoperatively, the vaginas extracted and sent to immunohistochemical analysis for the assessment of the pro-inflammatory agent TNF-α, anti-inflammatory agents TGF-β and IL-13, collagen metabolism marker MMP-2, and angiogenesis marker CD-31. AxioVision™ image analysis was used for the calculation of the immunoreactive area and density. Statistical analysis was performed with ANOVA followed by Tukey test (p <0.05). Results: Animals in the PRP group showed significantly increased expression of the angiogenesis agent CD-31 at all experimental times when compared to the PP group (p <0.0001). However, no differences concerning the expression of the other markers were observed between the groups. Conclusion: The addition of autologous PRP gel to PP meshes can be simply and safely achieved and seems to have a positive effect on implantation site angiogenesis. Further investigations are required to ascertain PPR coated meshes clinical efficacy in prolapses and stress urinary incontinence surgeries.

Abstract
Introduction: The platelet-rich plasma (PRP) is part of a set of biotechnologies, providing some growth factors that promote repair of different tissues. The polypropylene meshes (PPM) are applied in the correction of abdominal defects, pelvic floor and urinary incontinence, however, they induce many significant complications, as a result of an inappropriate inflammatory response. Purpose: To investigate the changes caused by PRP associated with the implantation of PPM in the abdomen of female rabbits, in the production of collagen I and III and the inflammatory infiltrate (ININ). Materials and Methods: We performed implant meshes with and without PRP in adult rabbits (n=30) and euthanasia at 7, 30 and 90 days. Two plates were prepared from each animal and analyzed in five different fields. The ININ was evaluated by quantification of inflammatory cells using hematoxylin-eosin and the collagen by Sirius red method. The results were analyzed applying the Wilcoxon, Kruskal-Wallis, Junckheere and Friedmann tests. Results: There was a significant difference in the number of inflammatory cells between the groups with and without PRP (p=0.01) at 90 days. There was increased production of collagen I, III and total with the use of PRP, at seven days. Conclusion: The PPM coating with PRP was associated with increased ININ at the implant area, and an increasing trend during the process of tissue repair. The PPM coated with PRP was related to increased concentration of collagen I, collagen III and the concentration of total collagen increased after seven days of implantation.

Abstract
Background Platelet rich plasma (PRP) has attracted attention in a number of surgical fields due to a wide variety of potential clinical benefits. Yet PRP has not gained wide popularity in aesthetic surgery as a result of uncertainty surrounding objective clinical evidence. Objectives We aim to describe the current applications, define preparation and activation, explore effectiveness, and propose a classification system to facilitate comparisons across studies. Methods A comprehensive review of the literature regarding the use of platelet rich plasma in aesthetic surgery was performed. Data gathered included: PRP application, study type, subject number, centrifugation, anticoagulation, activation, PRP composition, and outcomes. Results Thirty-eight reports were identified. Applications included injection into aging skin (29%), scalp alopecia (26%), lipofilling (21%), fractional laser (13%), and facial surgery (11%). The majority of studies (53%) were case series without controls. Leucocytes were sparsely defined (32%). The concentration of injected and/or baseline platelets was rarely clarified (18%). The mechanism of activation was described in 27 studies (71%), while anticoagulation was uncommonly elucidated (47%). While most studies (95%) claim effectiveness, objective measures were only utilized in 17 studies (47%). Conclusions Current studies produce context-dependent results with a lack of consistent reporting of PRP preparation, composition, and activation in aesthetic applications, making meaningful meta-analysis unrealistic. Thus the method of PRP preparation warrants increased attention. We recommend a set of descriptors, FIT PAAW (described below), to produce scientifically grounded conclusions, facilitating a clearer understanding of the situations in which PRP is effective.

Tehranian A, Esfehani-Mehr B, Pirjani R, Rezaei N, Sadat Heidary S, Sepidarkish M. Application of Autologous Platelet-Rich Plasma (PRP) on Wound Healing After Caesarean Section in High-Risk Patients. IRANIAN RED CRESCENT MEDICAL JOURNAL 2016; 18:e34449. [PMID: 27660723 PMCID: PMC5027131 DOI: 10.5812/ircmj.34449] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/09/2015] [Revised: 12/24/2015] [Accepted: 02/09/2016] [Indexed: 02/06/2023]
Abstract
Background Platelet-rich plasma (PRP) is a human plasma product enriched by platelets, growth factors, and fibrinogen with high hemostatic and healing properties. Objectives The aim of this study was to evaluate the effect of autologous PRP on wound healing in high-risk women undergoing cesarean sections. Patients and Methods In this balanced, randomized, and controlled trial, 140 patients were admitted to Arash women’s hospital, Tehran, Iran from May of 2013 to November of 2014 for elective cesarean surgery. The patients were randomly assigned into two groups. The intervention group received PRP after surgery, whereas the control group received the usual care. All patients were evaluated at baseline, five days, and eight weeks after the cesarean section. The primary endpoint used the REEDA scale for assessing the changes in wound healing. The secondary outcome measures used were the Vancouver scar scale (VSS) and the visual analog scale (VAS). All scale scores were analyzed using a repeated measures test for variance. Results At the end of study, the PRP group showed a greater reduction in the edema ecchymosed discharge approximation (REEDA) score compared to the control group (85.5% reduction in the PRP group; 72% in the control group) (P < 0.001). Compared with the control group, the PRP group had a significantly greater reduction in the VAN score, beginning on the fifth day after the cesarean section (-0.7, 38% reduction in PRP group; -0.8, 33% in control group) (P < 0.001), and this trend was stable at the end of the eighth week (-0.6, 54% reduction in PRP group; -0.3, 18% in control group). Furthermore, patients treated with PRP experienced a 93% reduction in the VAS score at the end of follow-up, but the control group only observed a 79% reduction (P < 0.001). Conclusions It seems that applying PRP is an effective therapeutic approach for wound healing, and faster wound healing is expected due to the presence of more platelets and growth factors.

Attachment of Primary Vaginal Fibroblasts to Absorbable and Nonabsorbable Implant Materials Coated With Platelet-Rich Plasma: Potential Application in Pelvic Organ Prolapse Surgery. Female Pelvic Med Reconstr Surg 2016; 21:190-7.

Abstract
OBJECTIVES Pelvic organ prolapse (POP) is a common condition in women. The lifetime risk of undergoing surgery to correct POP is 11%, with 30% recurrence rate. Various types of vaginal implants, absorbable and nonabsorbable, that have been introduced in pelvic floor reconstructive surgeries have numerous serious adverse effects. Platelet-rich plasma (PRP) is an autologous product that accelerates tissue healing and regeneration. We hypothesized that autologous PRP will promote human vaginal fibroblast (HVF) attachment to vaginal implants and increase their healing potential. METHODS Vaginal tissue biopsies were collected from postmenopausal patients with POP (n = 10) and asymptomatic control subjects (n = 4) during vaginal hysterectomy or repair. Primary cells were isolated and characterized by immunocytochemistry. Cell attachment and proliferation were compared between POP HVFs and control HVFs (n = 4/group). Twelve weeks after the surgery, blood samples were collected from 6 POP patients to obtain autologous PRP. Two meshes, absorbable (Vicryl) and nonabsorbable (Restorelle), were coated in PRP or control media; autologous POP HVFs (n = 6) were seeded on meshes for 2 hours. Cells attached to the meshes were fixed, stained with DAPI (4,6-diamidino-2-phenylindole dihydrochloride), and counted. RESULTS Pelvic organ prolapse HVFs were similar to control HVFs in attachment to different matrix substrates and in proliferation rate. Attachment of POP HVFs to both meshes was significantly increased after coating with PRP versus Dulbecco modified Eagle medium (Vicryl: 9875 vs. 1006 cells/cm, Restorelle: 3724 vs. 649 cells/cm; P < 0.001 for both). CONCLUSIONS In vitro, primary POP HVFs show better attachment to implant materials when treated with PRP, which may lead to reduced mesh-related complications in vivo, indicating its great potential for urogynecologic surgeries.

Growth factors, silver dressings and negative pressure wound therapy in the management of hard-to-heal postoperative wounds in obstetrics and gynecology: a review. Arch Gynecol Obstet 2015; 292:757-75. [PMID: 25864095 PMCID: PMC4560760 DOI: 10.1007/s00404-015-3709-y] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2014] [Accepted: 04/02/2015] [Indexed: 12/18/2022]
Abstract
Purpose The last two decades witnessed the development of numerous innovative regimens for the management of patients with abnormally healing and infected wounds. Growth factors, negative pressure wound therapy (NPWT) and antiseptic dressings containing silver are examples of methods with best documented efficacy, being widely used in the treatment of acute and chronic post-traumatic wounds, burns and ulcers of various etiology. As far as obstetrics and gynecology are concerned, prevention and treatment of infected, hard-to-heal postoperative wounds is of crucial importance. This article reviews the available literature to discuss the possibilities for use, efficacy and cost-effectiveness of growth factors, NPWT and silver dressings in the treatment of difficult-to-heal postsurgical wounds in obstetrics and gynecology. Materials and methods An extensive search of the English and Polish literature via PubMed and EMBASE databases was undertaken for articles published between January 1960 and April 30, 2014 to identify articles that described and assessed use, efficacy and cost-effectiveness of growth factors, silver dressings and NPWT in patients with hard-to-heal postoperative wounds following obstetric or gynecological surgery. Conclusions Literature review regarding the use of growth factors, NPWT and silver dressings suggests that these methods may play an important role in the management of wounds after invasive obstetric and gynecological procedures. Obese patients, patients after vulvectomy or prior radiation therapy may benefit most, however, due to non-numerous randomized reports, prospective studies on the use of above-mentioned methods in the treatment of postsurgical wounds following obstetric and gynecological interventions are required.

[PMID: 25386658 PMCID: PMC4227876 DOI: 10.1371/journal.pone.0112892] [Citation(s) in RCA: 29] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2014] [Accepted: 10/16/2014] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND Running economy and performance in middle distance running depend on several physiological factors, which include anthropometric variables, functional characteristics, training volume and intensity. Since little information is available about hematological predictors of middle distance running time, we investigated whether some hematological parameters may be associated with middle distance running performance in a large sample of recreational runners. METHODS The study population consisted in 43 amateur runners (15 females, 28 males; median age 47 years), who successfully concluded a 21.1 km half-marathon at 75-85% of their maximal aerobic power (VO2max). Whole blood was collected 10 min before the run started and immediately thereafter, and hematological testing was completed within 2 hours after sample collection. RESULTS The values of lymphocytes and eosinophils exhibited a significant decrease compared to pre-run values, whereas those of mean corpuscular volume (MCV), platelets, mean platelet volume (MPV), white blood cells (WBCs), neutrophils and monocytes were significantly increased after the run. In univariate analysis, significant associations with running time were found for pre-run values of hematocrit, hemoglobin, mean corpuscular hemoglobin (MCH), red blood cell distribution width (RDW), MPV, reticulocyte hemoglobin concentration (RetCHR), and post-run values of MCH, RDW, MPV, monocytes and RetCHR. In multivariate analysis, in which running time was entered as dependent variable whereas age, sex, blood lactate, body mass index, VO2max, mean training regimen and the hematological parameters significantly associated with running performance in univariate analysis were entered as independent variables, only MPV values before and after the trial remained significantly associated with running time. After adjustment for platelet count, the MPV value before the run (p = 0.042), but not thereafter (p = 0.247), remained significantly associated with running performance. CONCLUSION The significant association between baseline MPV and running time suggest that hyperactive platelets may exert some pleiotropic effects on endurance performance.

Abstract
Background Degenerative rotator cuff tears are a significant cause of shoulder pain in the aging population. Rotator cuff repair surgery may be more successful when growth factors are delivered to the repair site. This study was designed to determine the cellular processes involved in normal bone-to-tendon healing and the current approaches used for biologic augmentation of rotator cuff repair. Methods This review focuses on animal studies of rotator cuff repair and early human trials. Results Regular bone-to-tendon healing forms a fibrous junction between tendon and bone that is markedly different from the original bone-to-tendon junction. Tendon augmentation with cellular components serves as scaffolding for endogenous fibroblastic cells and a possible source of growth factors and fibroblastic cells. Extracellular matrices provide a scaffold for incoming fibroblastic cells. However, research in extracellular matrices is not conclusive due to intermanufacturer variation and the lack of human subject research. Growth factors and platelet-rich plasma are established in other fields of research and show promise, but have not yet been rigorously tested in rotator cuff repair augmentation. Conclusions Rotator cuff repair can benefit from biologic augmentation. However, research in this field is still young and has not yet demonstrated that the benefits in healing rates are significant enough to merit regular clinical use. Randomized controlled trials will elucidate the use of biologic augmentation in rotator cuff repairs.
