Tinnitus and Treatment With umPEA-LUT
Summary
Tinnitus can have different causes. From a peripheral point of view, the sensation of hearing a not present sound can be indicative of damage in the cells of the cochlea. Damage at this level can arise from traumatic, vascular, toxic origins or be caused by systemic pathologies. However, all the previous causes have a common denominator, the presence of reactive oxygen species (ROS), in the cochlea which determines the damage and the consequent death of the hair cells into the ear. The sound (tinnitus) that the patient perceives is generated by the spontaneous movement of the cilia of the hair cells; this phenomenon arises when these cells begin to be damaged. Tinnitus can be also caused by a retrocochlear disorder such as damage of the auditory nerve (inflammatory and tumor cause). In case of an inflammatory origin, the factors released during inflammation can locally damage the nerves and spread into the cochlea destroying the hair cells. Tinnitus can also originate from damage in the central auditory pathway. In this case, the problem persistent. It is important to keep in mind that although initially the tinnitus may originate from a damage inside the cochlea, after 6 months of persistence chronicizes causing an activation (without stimulus) of the upper auditory areas. This zone of "hypersensitivity" is therefore responsible for chronic tinnitus. In addition to the overmentioned medical causes, tinnitus can also be sign of psychiatric/psychological disorders, in those cases in whom there is an involvement of the hypothalamus, as showed by neuropsychological studies. Tinnitus can be temporary and disappear spontaneously or, in the most of cases, be persistent and extremely annoying/stressful for the patient. At night in particular, in the absence of noise, the patient suffers more the presence of this ghost sound, which in some occasions prevents sleep. Insomnia negatively impacts on tinnitus increasing its duration and intensity, thus establishing a perpetual cycle of stress into the brain. The latter phenomenon worses and chronicizes the symptom . Stress causes inflammation with ROS increase, which can affect both the peripheral and central auditory pathways. Recently, it has been shown that tinnitus can be a symptom of neuro-inflammatory pathologies such as, for example, Multiple Sclerosis. The effects of inflammation on the hair cells are identifiable only through electrophysiological studies or from the temporal bone. Keeping on mind inflammation and neuro-inflammation and considering the exchange between cerebrospinal fluid and perilymph , we speculate that the use of a molecule capable of reducing inflammation and modulating the action of mast cells and microglia, could be an effective tool to resolve tinnitus; moreover, thanks to its powerful action at the level of neuro-inflammation, it could reduce the hyper-activity in the upper auditory tracts, thus reducing/abolishing noise. umPeaLut combines palmitoylethanolamide, which modulates the activity of mast cells, macrophages and microglia and luteolin, a bioflanoid extracted from fruits with anti-oxidant properties, able to improve microcirculation. Because the alterations of the ear microcirculation can be an additional cause of tinnitus, we believe that luteolin content can be an ulterior benefit. Although various attempts have been made to use a mono-molecule, recent studies have shown that combination of several elements could reduce tinnitus ; PeaLut, in its ultra-micronized form with high bioavailability, could be the perfect solution. This study aims at evaluating the efficacy of umPEALUT as a therapeutic treatment of tinnitus in a sample of adults.
