Filter by:This research study is a randomized controlled trial in pediatric and young adult patients who have lost their sense of smell due to COVID-19 viral infection. The goals are: 1. to learn more about the effects of smell retraining therapy on smell loss following COVID-19 and 2. to determine if budesonide-saline irrigations make smell retraining therapy more effective.
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.
ivermectin is FDA approaved antiparasitic drug which is also claimed to be having potent in vitro antiviral effect,so we are tryying to study itsovid19 anosmia effect upon releiving post covid19 anosmia
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.
The loss of smell and taste is a prominent symptom of COVID-19. Studies found that patterns of smell loss due to Covid-19 infection differ from that of other respiratory viruses being much more profound in the Covid-19 patents and did not associate with runny, congested, or blocked-up nose. The researchers suggest that smell and taste testing can be used for fast COVID-19 screening. Studies found that the Covid-19 virus has similarities with severe acute respiratory syndrome coronavirus (SARS-CoV), which has been reported to enter the brain, via smell receptors in the nose. The sudden onset and relatively fast recovery in some patients suggest that COVID-19 anosmia is not caused by damage to the central nervous system but rather by the loss of smell information before it gets to the brain (smell receptors). They also found that it has different behavior from other respiratory viruses as it causes over-reaction of the immune system (or a cytokine storm). Trials to treat post-COVID anosmia using local steroid applications, sniffing of strong odors or scents or use of different vitamins (for several weeks to months) did not provide rapid, satisfactory or even significant recovery of olfactory dysfunction. Fortunately, the olfactory neurons can regenerate, however, studies reported variable prognoses, some patients recovered within weeks which others may have persistent deficits for months or even a year. In this study, the researchers hypothesize that cerebrolysin, a drug of neurotrophic and neuroprotective properties, can be used to treat patients with persistent post-COVID anosmia or ageusia or promote functional recovery of smell and taste deficits.
Anosmia is a symptom present in 40 to 80% of patients and usually only lasts 1 to 2 weeks. However, in nearly one in five patients, it can last beyond or even several months with consequences in terms of undernutrition and depression. However, olfactory rehabilitation is a technique validated in post-infectious anosmia since 2014 and recommended by international learned societies to accelerate recovery with nearly 63% improvement in anosmia In the context of the health crisis linked to the coronavirus, approximately 1 million French people will have persistent anosmia following an infection with COVID-19. A web-application to support the olfactory coaching of anosmic patients and help with follow-up seems relevant to promote recovery and the proper conduct of this coaching. covidanosmie.fr is a web application dedicated to olfactory rehabilitation, accessible free of charge.
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.
Evidence of COVID-19 related anosmia and dysgeusia continues to accumulate daily. Currently, up to 80% of patients report subjective olfactory dysfunction (OD), and prevalence using objective olfactory testing could be even higher. We propose a phase II single-site, double-blinded, placebo-controlled randomized clinical trial to determine the efficacy and safety of intranasal theophylline, a known phosphodiesterase inhibitor in the treatment of asthma, as a possible treatment for COVID-19 related OD. Theophylline has shown benefit in similar clinical trials for post-viral OD.
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.
The main aim of this study is to determine the effects of short-term treatment with hesperidin on COVID-19 symptoms in comparison with a placebo. Treatment effects will be observed through a symptoms diary that will be completed by participants throughout the study and by taking the oral temperature daily.
