Introduction: Autologous platelet-rich plasma (PRP) has been a growing trend in the field of medicine due to its broad range of application and is considered safe from bloodborne diseases. Furthermore, various studies have tried to optimize the use of autologous PRP through various preparation protocols, including PRP activation. However, most of the studies available have not evaluated the safety for intravenous delivery of PRP, especially autologous activated PRP (aaPRP). Therefore, this study aimed to evaluate the safety of intravenous delivery of aaPRP.Methods: Blood was drawn from each patient and aaPRP was isolated through calcium activation and light irradiation. Each aaPRP was administered intravenously to all patients. Adverse events were documented and analyzed.Results: Six hundred eleven patients participated in this study with a total of 4244 aaPRP therapies. Quality control of autologous aaPRP showed no platelets present after both calcium activation and light irradiation. No adverse events such as allergic reaction, infection, and coagulation problems were observed on all patients over the course of the study.Conclusion: Our results showed that intravenous administration of autologous aaPRP is safe even in patients with various pathological conditions.
In most people, COVID-19 presents as a mild disease. However, in many people, especially those with comorbidities, profound inflammation manifesting as a cytokine storm may lead to acute respiratory distress syndrome and multi-organ failure. This novel study reports two severe COVID-19 patients from Koja Regional Hospital: a male aged 52 and a female aged 65. Both patients had poor prognoses based on prognostic biomarkers, disseminated intravascular coagulation, nosocomial infections, and were reintubated more than once. Both patients were treated with adjunct autologous activated platelet-rich plasma -a safe and promising therapy -and were ultimately discharged. Thus, this study reports the potential of autologous activated platelet-rich plasma as supportive therapy for severe COVID-19 patients.
Introduction and Aim: Activated autologous platelet-rich plasma (aaPRP) is becoming a popular therapy to accelerate healing in the field of plastic surgery. Platelets, which are abundant in aaPRP, can release many growth factors including platelet-derived growth factor (PDGF) and vascular endothelial growth factor (VEGF). This study aims to examine the plasma levels of PDGF and VEGF in healthy subjects after intravenous administration of aaPRP.
Materials and Methods: Nine healthy patients with no prior history of metabolic disease were divided into two groups (control and experiment group). The treatment group which consists of six patients received intravenous aaPRP treatment. The preparation of aaPRP starts with the collection of 24 mL of whole blood in sodium citrate tubes followed a two-step centrifugation procedure and subsequent chemical activation. aaPRP was then administered intravenously to patients. Meanwhile, the control group received no intervention. Venous blood samples were taken before and one week after the treatment and the plasma PDGF and VEGF levels were determined by enzyme-linked immunosorbent assay (ELISA).
Results: The treatment group showed statistically significant increase in VEGF after 7 days compared to before aaPRP administration. However, the change in PDGF levels of the treatment group was unnotable.
Conclusion: The present findings indicate that intravenous administrations of activated aaPRP may increase plasma VEGF level up to 1 week after aaPRP administration.
