Clinical manifestations of allergic reactions and immunoglobulin E levels on allogeneic freeze-dried platelet-rich plasma (PRP) application

Background: Several studies have reported that modern wound dressings offer better results. Allogeneic PRP products in the form of injections and gels are available in the market, which helps accelerate wound healing without triggering an immunological reaction. Meanwhile, this study was carried out to investigate the Allogeneic Freeze-Dried PRP form, which is more practical, efficient, and safer. This study aims to determine the effect of Allogeneic Freeze-Dried PRP on human splitthickness skin graft donor wounds on clinical manifestations of allergic reactions and levels of Immunoglobulin E (IgE).Methods: A randomized Pre- and Post-test Control-Trial Group Design was conducted on patients with split-thickness skin graft donor wounds using Allogeneic Freeze-Dried PRP dressings at Dr. Soetomo General Hospital, Surabaya. Allergic manifestations were reviewed during the observation period of up to 4 days, and IgE levels were measured pre-test and 60 minutes post-application. A statistical comparison of results was carried out between the trial and control groups that used paraffin dressings.Results: A total of 36 patients were used as subjects, with 19 (52.78%) in the trial group and 17 (47.22%) in the control group, and their parameters were generally homogeneous. There were no clinical manifestations of allergic, changes in vital signs, and significant differences in IgE levels before and after application statistically in all study subjects (p>0.05).Conclusion: Application of Allogeneic Freeze-Dried PRP to human split-thickness skin graft donor wounds did not generate clinical manifestations of allergic reactions and an increase in IgE.
