[The use of autologous platelet-rich plasma in the treatment of chronic pharyngitis].

The results of a prospective open cohort study of the use of platelet-rich plasma (platelet-rich plasma - PRP) in patients with chronic pharyngitis during the exacerbation of the disease are presented.

Objective: To evaluate the clinical efficacy of autologous PRP in the treatment of chronic pharyngitis.

Material and methods: Autologous PRP was injected into the posterior pharyngeal wall as a course of endopharyngeal blockages as part of the complex therapy of chronic pharyngitis. Patients in the control group received standard therapy, without the use of autologous PRP. The effectiveness of the studied technique was evaluated by statistical analysis of the intensity of symptoms of the disease, determined by patients throughout the entire period of treatment in the patient's diary, as well as by analyzing data from mass spectrometry of microbial markers and bacteriological examination of the pharyngeal mucosa, collected at the beginning of the study and 14 days after completion of the course of therapy.

Conclusion: The use of a course of endopharyngeal blockades with autologous platelet-rich plasma as part of the complex therapy of chronic pharyngitis, according to our estimates, provides a significant effect in the form of higher rates of reduction in the severity of symptoms of the disease, a significant reduction in the number of microorganisms deviating from the reference values (by 2 times or more), a decrease in the duration of the disease compared with the control group.
