Platelet-rich plasma in the treatment of alopecia

Platelet rich plasma (PRP) is a promising treatment choice for patients with thinning hair. Despite excellent clinical safety and low cost, its clinical standing is still weak. The effectiveness of this method depends on its dosage, number of sessions, their intervals and technique of injection incorporated. PRP can produce particularly some phenomenal effects when applied in cosmetic dermatology. The therapeutic value of PRP is equivalent to stem cells and considered as one of the promising therapeutic agents in regenerative medicine. Harvesting of PRP plays a significant role, which is obtained from the patient's blood after centrifugation of the sample i.e., the platelet concentrates above the baseline which is the plasma fraction of the autologous blood. There are many applications of PRP in the medical field and has an incredibly significant role in dermatologic conditions e.g., tissue regeneration, wound healing, scar revision, skin rejuvenation and alopecia. In this review, we will be analyzing the authenticity of the use of PRP in the treatment of alopecia. PRP, in current scenario, is considered as a novel treatment modality. The efficacy of PRP therapy carries some deficiencies, which include lacking standard in preparation and concentration of platelets in PRP.

With the advanced and improved knowledge of bone regeneration on the molecular level, some of key molecules that alter the complicated physiological method were identified, and are already in scientific use or beneath research to enhance bone restore. Of those molecules, BMPs were the maximum considerably studied, as they are robust osteoinductive elements. They result in the mitogenesis of mesenchymal stem cells (MSCs) and different osteoprogenitors, and their differentiation in the direction of osteoblasts. Other growth factors except BMPs which have been implicated through out the bone regeneration, with one-of-a-kind features with respect of cell proliferation, chemotaxis and angiogenesis, are also being investigated or are presently getting used to reinforce bone restore, which include platelet-derived growth factor, transforming growth factor- β, insulin-like growth factor-1, vascular endothelial growth factor and fibroblast growth factor, amongst others. One present day technique to enhance bone regeneration and soft-tissue recovery with the aid of using nearby application of growth factors is the use of platelet-rich plasma, an extent of the plasma fraction of autologous blood with platelet concentrations above baseline, that is wealthy in most of the aforementioned molecules. This overview focuses and target on the biological mediators that regulates key cellular events which have a capacity to induce the method of tissue repair and regeneration.

Abstract: Platelet rich plasma (PRP) is a biological product defined as a portion of the plasma fraction of autologous blood with a platelet concentration above the baseline. The plasma occupies 55% of blood, which is rich in immunoglobulins and proteins that have a wide range of applications in various medical fields. Plasma therapy is applied to tackle various disorders or diseases as it induces the body to develop new healthy cells. It contains important components like antibodies, coagulation factor, enzymes, fibrinogen, proteins and albumin. PRP is a unique and advanced treatment which helps to increases the body’s natural healing process. Platelet lysate which is obtained from platelet rich plasma consist of various growth factors such as chemokines, cytokines, and antibacterial molecules and also has anti-inflammatory, immunomodulatory, anti-fibrotic and repairing effects. As PRP is rich in the proteins and several antibodies, it is used for various chronic therapies such as hemophilia and autoimmune disorders as well as in various severe health problems. Lyophilized Platelet-rich plasma (LPRP) therapy is currently used in various fields such as in tissue regeneration, wound healing, scar revision, skin rejuvenating effects, alopecia and for the coronavirus disease (COVID-19). It is also used to heal wounds and illnesses. LPRP therapy is gaining attraction by many health professionals as it is a safe, effective, efficient, and easy approach in procuring, preserving, and therapy.

AbstractAutologous blood-derived products such as platelet-rich plasma (PRP) are widely used to treat musculoskeletal conditions, including knee osteoarthritis (OA). However, the clinical outcomes after PRP administration are often variable, and there is limited information about the specific characteristics of PRP that impact bioactivity and clinical responses. In this study, we aimed to develop an integrative workflow to evaluate responses to PRP in vitro, and to assess if the in vitro responses to PRP are associated with the PRP composition and clinical outcomes in patients with knee OA. To do this, we used a coculture system of macrophages and fibroblasts paired with transcriptomic analyses to comprehensively characterize the modulation of inflammatory responses by PRP in vitro. Relying on patient-reported outcomes and achievement of minimal clinically important differences in OA patients receiving PRP injections, we identified responders and non-responders to the treatment. Comparisons of PRP from these patient groups allowed us to identify differences in the composition and in vitro activity of PRP. We believe that our integrative workflow may enable the development of targeted approaches that rely on PRP and other orthobiologics to treat musculoskeletal pathologies.

Background. Autologous whole blood and platelet-rich plasma (PRP) have been both suggested to treat chronic tennis elbow. The aim of the present study was to compare the effects of PRP versus autologous whole blood local injection in chronic tennis elbow. Methods. Forty patients with tennis elbow were randomly divided into 2 groups. Group 1 was treated with a single injection of 2 mL of autologous PRP and group 2 with 2 mL of autologous blood. Tennis elbow strap, stretching, and strengthening exercises were administered for both groups during a 2-month followup. Pain and functional improvements were assessed using visual analog scale (VAS), modified Mayo Clinic performance index for the elbow, and pressure pain threshold (PPT) at 0, 4, and 8 weeks. Results. All pain and functional variables including VAS, PPT, and Mayo scores improved significantly in both groups 4 weeks after injection. No statistically significant difference was noted between groups regarding pain scores in 4-week follow-up examination (P>0.05). At 8-week reevaluations, VAS and Mayo scores improved only in PRP group (P<0.05). Conclusion. PRP and autologous whole blood injections are both effective to treat chronic lateral epicondylitis. PRP might be slightly superior in 8-week followup. However, further studies are suggested to get definite conclusion.

Autologous Platelet

Introduction: Venous ulcers are wounds that are thought to occur due to improper functioning of venous valves, usually of the lower limbs. Considering that PRP is a source of growth factors, and consequently has mitogenic, angiogenic, and chemotactic properties, it represents an adjunctive treatment for recalcitrant wounds. Moreover, PRP provides the wound with adhesive proteins, such as fibrinogen, which are important in wound healing. PRP contain more amount of platelets, cytokines and growth factors which are dispersed in a very small amount of plasma which can be prepared from a sample of centrifuged autologous blood. Application of PRP has been reported to be effective in both acute as well as chronic non healing venous ulcers. Aim and Objective: To evaluate the efficacy of autologous platelet rich plasma in the management of chronic venous ulcer. Material and Method: A Prospective study conducted on 100 patients of chronic venous ulcers admitted in Sir T. Hospital Bhavnagar from June 2018 to June 2019 after fulfilled our inclusion and exclusion criteria. PRP then injected intalesionally inside and around the periphery of the wound/ulcer. This process was done once/week for 12 weeks. At every week, the area and volume of ulcer was calculated and photographs were taken. Result: All the patients showed healing of the ulcer with reduction in size of ulcer more than 90% was observed in 72 patients, followed by 80–90% reduction in wound size in 18 patients after the 12 weeks follow-up. Overall, significant reduction in size of ulcer was observed in all the treated patients. Conclusion: Autologous platelet rich plasma (PRP) as an autologous method, it is biocompatible, simple, safe, affordable and less expensive procedure in the treatment of chronic venous ulcers. PRP is found to be useful in improving and enhancing the healing process in chronic venous leg ulcers without any side effect. Keywords: Venous ulcer, Platelet rich plasma
