MOLECULAR MECHANISMS OF NOCICEPTION IN CHRONIC PROSTATITIS

Abstract

Introduction. The need to understand the pathophysiology of prostatitis is determined by its prevalence, usually chronic progressive course, significant impact on quality of life, fertility and sexuality. The modern arsenal of medicines allows us to achieve a clinically significant effect. Along with this, non-pharmacological methods are widely used to increase the effectiveness of treatment. However, despite significant successes in the treatment of prostatitis, the problems of insufficient efficiency remain unsolved by modern urology, and it is extremely difficult to help these patients. Understanding the pathophysiology of the disease has always been the key to successful diagnosis and treatment. That is why it is important to determine the mechanisms of development of painful manifestations of prostatitis. The aim. To describe the main molecular mechanisms of tissue damage reception, in particular of the prostate gland, which are perceived as pain sensations. Materials and methods. An evaluation of modern literature devoted to the mechanisms of creation of nerve impulses due to damage and inflammation of the prostate gland was carried out. The search was conducted in the MEDLINE and databases of the National Library of Ukraine named after V.I. Vernadsky. Results. The main molecular mechanisms of nociception in chronic prostatitis have been determined. A review of modern literature devoted to the study of pain mechanisms as a biologically significant signal of damage at the molecular level of reception is presented. Attention is focused on the features of nociception in prostatitis, its connection with the production of inflammatory mediators, possible mechanisms of hyperalgesia and allodynia. As a result of stress and tissue damage, the production and release of inflammatory mediators such as interleukins, interferon, prostaglandins, bradykinin, adenosine triphosphate, protons and nerve growth factor increase. These mediators activate pain receptors located on nerve endings and are ion channels of various types: transient receptor potential, acid, purinergic, and potassium ion leak channels. Conclusions. The presented literature data describe the mechanisms of nociception, hyperalgesia and allodynia in chronic prostatitis, the understanding of which can be the basis for the development of new methods of diagnosis and treatment.
