简要总结
The main objective of our study is to evaluate the effect of combinated antioxidants therapy with Adepsique® (amitriptyline, perphenazine, and diazepam) on patients with tinnitus chronic symptoms, evaluating the levels of inflammatory cytokines and oxidative stress in blood.
The researchers intend to include 58 patients, divided into two intervention groups, who will be randomly assigned a pill with antioxidants or placebo, and the patient must eat one pill per day for 3 months.
In the study, the clinical characteristics of tinnitus, inflammatory cytokines and oxidative stress markers will be evaluated, before, during and after the intervention with antioxidant therapy. Subsequently, the clinical and sample results will be evaluated to compare the effects between them.
详细描述
Tinnitus is a pathology defined as the perception of a sound without an external acoustic stimulus. About 15 to 20% of the world population suffers from this pathology.It is classified according to the time of presentation (acute or chronic); in the existence of an internal source measurable and perceptible by the patient and the physician (objective) or where the source does not exist and is only perceived by the patient (subjective), the latter being the most common. And, in the place where they originate, exotic (outside the ear), endotic (within the auditory apparatus), and central (within the cerebral cortex without lesion of the auditory apparatus). As well as the influence it presents in daily life, being mild, moderate, severe or catastrophic.
Within the pathophysiology, the influence of different proinflammatory cytokines such as IL-6, TNF-α, β-2GP1, IL-1, among others, is described; as well as markers of oxidative stress and elevated levels of ROS, which annul defense mechanisms against oxidative damage, and induce damage to DNA, lipids, and membrane proteins.ncreased levels of nitric oxide, peroxynitrite, nuclear transcriptional factor Kappa-B (NF-κB), glutamate (N-methyl D-aspartate) receptors, and calcium cause hair cell damage. On the other hand, reduced levels of antioxidant enzymes such as superoxide dismutase, glutathione peroxidase, glutathione reductase, catalase, and glutathione transferase perpetuate cell damage.
The diagnosis is based mainly on ruling out etiological factors, associated symptoms or existing comorbidities that cause tinnitus secondarily, as well as a detailed clinical history, measurement of hearing quality, and demonstration of the imbalance of neurotransmitters and proinflammatory molecules.
Because it is a multifactorial entity, the definitive treatment has not yet been developed. Extensive pharmacological therapies, from the use of NSAIDs to antidepressant and antipsychotic drugs, have been tried with ambiguous, inconsistent and inconclusive results. Alternative therapies with multivitamins and antioxidants have shown probable utility in the treatment of tinnitus, however, the existing evidence is of poor and conflicting quality.The latter reduce oxidative stress through different means; through the destruction of free radicals by donating electrons to the unpaired states of these radicals. Another means is through the catalysis of free radicals, converting them into harmless molecules (water and oxygen). Lastly, they support reducing chronic inflammation secondarily by decreasing the rate of auditory hairy cell apoptosis.
