Filter by:This study will investigate the efficacy of oral gabapentin in olfactory improvement following Covid-19- associated olfactory dysfunction. This is a randomized, double-blinded, placebo-controlled trial.
The aim of this study is to assess whether the use of a therapy combining olfactory training, corticoids, and phototherapy improves the PROMS compared to the use of olfactory training and corticosteroids only. To accomplish this goal the study will consist of 40 participants. The participants must present olfactory dysfunction for at least 4 weeks after a coronavirus-19 infection. Furthermore, to be eligible each participant will need a polymerase chain reaction test with positive results for coronavirus-19.
post covid-19 smell and taste dysfunction are common globally and affect the quality of life and also have phycological impact and anxiety, also affect on economy as the patients not able to do cooking or buy prepared foods and not eaten, also not able to enter the cooking room and prepare foods for themselves, also the risk of loss of smell the fire accidents because anosmia, many forms of smell dysfunction like anosmia ,hyposmia, and dysosmia ,Phantosmia , parosmia may occurred, the same taste disorders may has many forms like Dysgeusia, phantom taste perception, hypogeusia with dysgeusia. until now no definite treatments for post covid-19 smell and taste disorders , this study is novel study as quadruple therapy Intranasal Insulin, Zinc, Gabapentin, Ice Cube Stimulation may suspect having promising results
There are very few long-term studies that analyze the immune responses in patients recovered from COVID-19 caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The main aim of this study is to analyze the clinical profile and immune responses of recovered COVID-19 patients in a representative cohort of people in the Umbria region of Italy. The participants had a history of testing positive for SARS-CoV-2 in March 2020 by Reverse Transcriptase- Quantitative Polymerase Chain Reaction (RT-qPCR). The participants were invited for voluntary participation in a seroprevalence study. This study analyzes longitudinally the presence of antibodies against SARS-CoV-2 by sequential serological tests at different time points using two FDA-approved Immunoassays. At the first serum sample collection, the participants were asked to provide information about their COVID-19 clinical history including clinical profile, co-morbidities, and treatment undertaken using a standardized questionnaire. Successive sequential serological assessments were conducted to understand the immune responses in these recovered patients. Moreover, stage two of the study involves, analysis of antibody titers in recovered vaccinated individuals and their follow-up.
The aim of our study was to compare the recovery of smell in people suffering posttraumatic olfactory impairment following a systematic olfactory rehabilitation performed by occupational therapists to natural recovery in a control posttraumatic group of patients.
Background: Many people lose their sense of smell after they have had a cold, flu or sinus infection. Recovery (if at all) generally starts with a "parosmia" phase which means every-day smells become distorted and over-poweringly objectionable, and this can lead to malnutrition and depression. We do not know much about how or why parosmia happens, but there are key foods common to those who suffer from parosmia which seem to trigger the distortion. Parosmia and COVID-19 Loss of smell has recently been recognised as an official symptom of COVID-19, and we are starting to get reports of people who have recently had COVID-19 developing parosmia. The triggers seem to be similar to those of the common cold, flu or virus infections, but the journey between loss of smell and parosmia is different. Hypotheses 1. Triggers of distortion will be the same for all parosmics. 2. There may be additional trigger foods in different cultures. Questions 1. What are the trigger foods and beverages for parosmia? 2. Are there regional/cultural variations? 3. Does Covid-19 parosmia differ from "standard" post-viral parosmia? The overall aim of the project is to understand the mechanisms involved in parosmia. The approach is to identify foods and everyday aromas associated with parosmia and to determine whether they are the same across different continents/cultures/ethnic backgrounds, and whether Covid-19 parosmia is any different to non-Covid-19 parosmia. The questionnaire will ask about Covid-19 status, ethnic background, smell loss and parosmia, and the changes that occurred between smell loss and parosmia. The participants will then answer questions on up to 15 everyday smells, some of which our preliminary evidence shows are common triggers, and others which are not. The questionnaire will be globally distributed, for example through current collaborations in the UK, US, Germany, Iran, China, Japan and Brazil. It will be completed by participants who are currently experiencing parosmia. All participants will be asked to record any foods that they find distorted and provide a list of aromas which returned undistorted.
Olfactory dysfunction is common among patients with Corona-Virus-Infection-Disease (COVID)-19, and up to 30% of patients may report persistent disorders of smell or taste as a long-term sequelae. This randomized-controlled study has addressed to compare the efficacy of neuro-protective and anti-inflammatory agents palmitoylethanolamide (PEA) and Luteolin(Treatment) with control (olfactory training) in a cohort of patients who present persistent smell disorders after resolution from Covid-19 and negative swab for 4 months at least.
Covid 19 cause an olfactory loss in more than 80% of cases. This loss most often regresses but leaves 20% of patients with an olfactory complaint, particularly with regard to the quality of daily life. The neuro-cognitive implications involved with COVID19 and the consequences of persistent olfactory loss remain unknown. The effectiveness of therapeutic management, in particular olfactory re-education, has not yet been clarified. Objectives are the assessment of patients olfactory disorders, psychiatrics and neurocognitives specificities after a COVID, before and after treatment or specific cares.
According to WHO (World Health Organisation) data, about 40% of patients with COVID-19 (Corona Virus SARS-CoV-2) have a mild course of the disease, namely, cases of mild course are of great danger from the point of view of the spread of infection, since the main source of infection is a sick person. The mild course of COVID-19 is characterized by a number of nonspecific symptoms: fever, cough, sore throat, nasal congestion, malaise, headache, muscle pain. Evidence has emerged of loss of smell as a symptom of COVID-19 infection. Anosmia/hyposmia in the absence of other respiratory diseases, such as allergic rhinitis, acute rhinosinusitis, or chronic rhinosinusitis, are considered as a clinical marker of COVID-19 infection in a pandemic.For people with a mild course of the disease, WHO recommends providing home care, and the recommendations come down to observing a sanitary-hygienic regimen and taking antipyretics if necessary. Unfortunately, the treatment of patients with a mild course is still outside the interest of medical science. In its updated strategy to curb the spread of COVID-19, WHO states the need for diagnosis, effective isolation, and treatment of patients with mild to moderate severity of the clinical course of patients.Currently, there is experience with the use of the drug Imupret for the treatment of nasopharyngitis associated with other viral pathogens, in particular Epstein-Barr virus. It was shown that the use of a Phyto preparation helps to accelerate the regression of symptoms characteristic of nasopharyngitis, as well as accelerate the elimination of the virus from the body. Obviously, the proven activity of Imupret is important in relation to the activation of factors of nonspecific immunity, which is important in confronting viruses, including COVID-19. Another obvious factor that is important for the treatment of viral diseases is the synergism of the active substances in oak bark and walnut leaves with respect to inhibition of reverse transcriptase of a wide range of respiratory viruses, as well as the anti-inflammatory effect of the drug. Confirmation of the therapeutic effect of Imupret for the treatment of nasopharyngitis associated with COVID-19 would allow the development of new therapeutic tools to combat this infection and put into practice updated WHO emphasis on national health systems: it is important to identify, treat and isolate all cases of COVID-19, including cases with mild or moderate severity of the disease.
It is a randomized controlled clinical trial study that aims to follow a sample of individuals with persistent olfactory dysfunction post-COVID-19. The aim of this study is assess the clinical outcomes of olfactory training therapy in the treatment of persistent olfactory dysfunctions after COVID-19. The sample will consist of 350 participants, being 300 individuals with persistent olfactory dysfunction post-COVID-19 and 50 healthy individuals. Volunteers' will be separated in two experimental groups (1 and 2 ) and a control group. All participants will be submitted to clinical evaluation that include the Connecticut Chemosensory Clinical Research Test (CCCRT), an olfactory test to diagnose anosmia and hyposmia, and two skull Magnetic Resonance imaging (MRI). Only participants of Experimental group 1 will be submitted to an olfactory training with essences oils. Experimental group 2 will only receive a clinical follow-up after three months and control group will be only submitted to neurological exam, olfactory test, MRI imaging and test their ability to discriminate the essence oils used in olfactory training. As a result, is expected a better understanding of the characteristics of olfactory dysfunction caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) virus infection, as well as the effectiveness and viability of using Olfactory Training as a therapeutic alternative.
