17 Clinical Trials for Various Conditions
Persistent smell loss that can include diminished or distorted smell function is a common symptom of long COVID syndrome. There are limited treatment options for long COVID-related smell loss. This study aims to determine the efficacy of two at-home treatments, smell training and non-invasive trigeminal nerve stimulation. This study requires participants to conduct daily at-home treatment sessions, attend three in-person study visits at the MUSC Department of Psychiatry and Behavioral Sciences, and complete electronic questionnaires over the 12-week trial, and again at the six-month timepoint. Participants in this trial may benefit directly with an improvement in sense of smell. However, participation may also help society more generally, as this study will provide new information about long COVID-related smell loss and its treatment.
The purpose of this study is to determine if a trial of directed high-dose nasal steroids improves residual smell loss in patients with chronic rhinosinusitis following sinus surgery. Other outcomes of this study include: identifying the differences in sinus airflow between patients who improve following nasal steroid treatment and those who do not, and to see if, in patients who improve following surgery, the improvement remains throughout follow-up.
The goal of this observational study is to learn what can predict the return of the sense of smell in patients with chronic rhinosinusitis with nasal polyps being treated with dupilumab. The main questions it aims to answer are: 1. Does obstruction of the olfactory cleft predict return of the sense of smell? 2. Do electrophysiological signals generated by breathing and sniffing behavior predict return of the sense of smell? Participants starting dupilumab will undergo assessment for their degree of olfactory cleft obstruction, and an electrophysiologic assessment of their olfactory cleft and be followed over 6 months of treatment with dupilumab.
The goal of this clinical trial is to learn if ScentCare, a novel olfactory training device and accompanying companion web-based application, will lead to improved olfactory and well-being outcomes in elderly patients with Olfactory Dysfunction (OD). The main question it aims to answer is: - What effect does the olfactory training device (ScentCare) and accompanying companion web-based application have on olfaction? Researchers will compare ScentCare to solving Sudoku puzzles to see the effects of olfactory training using this novel device on olfaction. Previous studies have used Sudoku puzzles when studying the effect of smell training. Since smell training is thought to work by stimulating and engaging higher order cognition, Sudoku is a suitable activity for participants in the control group since it serves as a correlate with similar degree of stimulation. Participants will: * Use ScentCare (intervention) or solve Sudoku puzzles (control) twice daily for 3 months. * Visit the clinic twice, once upon enrollment and once three months later. * Complete a formal smell test using Sniffin' Sticks smell test at the beginning of the study and again at the end of the study (3 months) during the initial and follow up visit. * Complete questionnaires at the beginning of the study and again at the end of the study (3 months) during the initial and follow up visit.
Randomized, double-blinded, placebo-controlled trial to determine the safety and efficacy of CYR-064.
This is a phase II randomized, double-blinded, placebo-controlled study to evaluate the efficacy of topical intranasal treatment of beclomethasone vs. placebo for improved olfactory function.
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.
To capture the natural history of COVID-19 associated olfactory dysfunction as measured by two patient reported outcome measures (SNOT-22, QOD-NS) and a 6-week BSIT with a comparison to an intervention arm receiving daily omega-3 supplements.
Olfactory dysfunction is a defining symptom of COVID-19 infection. As the number of total, confirmed COVID-19 cases approached 19 million in the United States, it is estimated that there will be 250,000 to 500,000 new cases of chronically diminished smell (hyposmia) and loss of smell (anosmia) this year. Olfactory dysfunction is proposed to worsen numerous common co-morbidities in patients and has been shown to lead to a decreased quality of life. There are very few effective treatments for hyposmia or anosmia, and there is no gold standard of treatment. One proposed treatment option is smell training, which has shown promising yet variable results in a multitude of studies. It garners its theoretical basis from the high degree of neuroplasticity within the olfactory system, both peripherally and centrally. However, due to a relative inadequacy of proper studies on olfactory training, it is unknown what the most efficacious method in which to undergo the training is. This study proposes two novel procedural modifications to smell training in an attempt to enhance its efficacy. The investigators propose using a bimodal visual-olfactory approach, rather than relying on olfaction alone, during smell training, as well as using patient-preferred scents in the training that are identified as important by the study participant, rather than pre-determined scents with inadequate scientific backing. The investigators hypothesize that by utilizing bimodal visual-olfactory training and patient-selected scents, the olfactory training will be more efficacious and more motivating for participants.
The purpose of this study is to evaluate the performance of a non-invasive olfactory device as a rapid indicator of COVID-19 in positive subjects.
Post-acute sequelae of SARS-CoV-2 infection can cause multiple system function disorders, and complicated symptoms last for an extended period. The virus can cause this continued infection, or the virus causes immune system function disorder and post-infectious autoimmune disease. The clinical symptoms can be smell loss, taste loss to liver function disorder, kidney function failure, different. No matter how complicated the systems showed in the clinic, all of the symptoms are due to the specific cells being damaged. Our clinical study is focused on recovering the damaged structure and function of the cells that could restore the organ function back to normal or close to normal
Directly examine whether early (6-month) imaging with DaTscan and \[¹⁸F\] AV-133 will provide an early signal of disease progression in recently diagnosed untreated PD patients.
The Parkinson Progression Marker Initiative (PPMI) is a longitudinal, observational, multi-center natural history study to assess progression of clinical features, digital outcomes, and imaging, biologic and genetic markers of Parkinson's disease (PD) progression in study participants with manifest PD, prodromal PD, and healthy controls. The overall goal of PPMI is to identify markers of disease progression for use in clinical trials of therapies to reduce progression of PD disability.
The purpose of this research study is to evaluate the use of NAC in the treatment of anosmia (a loss of the sense of smell). This drug is already approved by the Food and Drug Administration (FDA) for oral or pulmonary (lung) inhaled use for other medical conditions. However, there is research evidence that the medication may promote nerve recovery (help nerves work better after they are damaged). Since anosmia involves nerve problems, we believe the nasal spray may help treat anosmia. The medication has been in use for many years for other conditions, without safety problems.
Background: People with hearing, balance, and taste, smell, voice, speech, language, and other Ear, Nose, and Throat (ENT) disorders may seek treatment at the National Institute on Deafness and Other Communication Disorders (NIDCD). Some of these people may benefit from enrolling in the NIDCD intramural research program to receive their care. Enrolling will also allow investigators to collect participants clinical data and specimens for future research. Objective: This natural history study has 2 goals: (1) to collect data and specimens that may be used for research; and (2) to evaluate participants who may be candidates for other research studies. Eligibility: People aged 2 years or older with a hearing, balance, and communication disorder. Those at risk or who are suspected of having such a disorder are also eligible. Design: Participants will be screened. Their medical records will be reviewed. Participants will agree to have their medical data used for research. Specimens such as blood or other tissue samples may also be used for research. All data and specimens will be collected during their routine care visits. All tests done will be the normal care for each participant s condition. No tests will be done solely for research. Some of these tests may require blood or tissue samples. Some may use special tools to test hearing and balance. Some may test heart or lung function. These tests may also include different types of imaging scans. All tests will be explained. Participants may ask questions at any time. Participants may remain in this study for up to 2 years. If they need further care, they may sign a new consent. ...
Background: Many disorders of the head and neck can affect a person s hearing; balance; smell; taste; swallowing; voice; or speech. These disorders include cancers and genetic and inflammatory diseases. To find better ways to diagnose and treat these disorders, researchers need to study tissues and other biological samples from people who have them. Objective: To collect biological samples for a repository that will be used for research. Eligibility: People of any age with a disorder of the head and neck that requires the taking of biological samples. The conditions may be any that affect hearing; balance; smell; taste; swallowing; voice; or speech. Design: Part 1: Participants will give permission for their leftover tissue samples to be used for research. These are tissue samples from the head and neck that were collected in the course of routine tests and care or other research studies. Information on each participant s age, diagnosis, and previous treatments will also be collected. Part 2: Some participants may be asked for more samples. All those aged 3 years or older will have a physical exam. They will provide blood and saliva samples. A cotton swab or brush will be used to collect cells from the inside of the cheek. Participants 18 years or older may have additional tests. They may provide nasal secretions: A piece of gelfoam or a sponge will be placed in the nose to soak up secretions for 5 to 10 minutes. They may have biopsies: Small samples of tissue will be cut from the skin and the tissue lining the mouth. Samples may be used for genetic testing.
The purpose of this study is to determine the impact of a twice daily at-home olfactory training program with a twenty scent, essential oil-based smell test in patients with olfactory dysfunction.
