Smell Changes & Efficacy of Nasal Theophylline

Olfactory DisorderAnosmia3 more

This study evaluates the efficacy and safety of nasal theophylline irrigation in treating smell loss related to a viral respiratory infection. Half the participants will undergo nasal theophylline irrigation treatment while the other half will undergo placebo nasal irrigation with saline alone. All participants will have their sense of smell tested before and after 6 weeks of treatment. All participants will also be regularly asked about any potential side effects related to treatment. In addition, the first 10 participants will have their blood drawn to measure their theophylline level after 1 week of starting treatment to ensure it is not abnormally elevated.

The Effect of Chinese Herbal Medicine as an Adjuvant Therapy in the Treatment of Traumatic Anosmia...

Traumatic Anosmia

Objective: To investigate the effect of Chinese herbal medicine (CHM) as an adjuvant therapy in the treatment of traumatic anosmia. Methods: Patients with a clear history of loss of smell after head injury, and whose phenyl ethyl alcohol (PEA) odor detection threshold remained -1 after treatment with steroid, zinc, and olfactory training (OT) for one month, were included in this study between September of 2018 and November of 2020. They were randomly divided into 2 groups, with patients in the CHM group taking CHM (tailored Guizhi decoction) and performing OT, and those in the OT group receiving OT only for 6 months. After 3 months' and 6 months' treatment, the olfactory function was evaluated by both the PEA threshold test and the traditional Chinese version of the University of Pennsylvania Smell Identification Test (UPSIT-TC). Magnetic resonance imaging was performed to measure the volume of olfactory bulbs after 6 months' treatment.

Olfactory Disfunction and Co-ultraPEALut

AnosmiaCovid193 more

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.

Visual-OLfactory Training in Participants With COVID-19 Resultant Loss of Smell

AnosmiaCovid195 more

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.

Lactoferrin for COVID-19-Induced Taste or Smell Abnormality

Covid19Taste Disorder6 more

Common side effects of corona virus disease 2019 (COVID-19) include disruptions in taste and smell function, which may persist for prolonged periods of time following recovery and resolution of COVID-19 infection. These disruptions not only reduce the hedonic pleasure derived from eating, but may also be detrimental to quality of life and could pose additional health risks (malnutrition) among patients with chronic illness or those enduring long-term complications from their previous COVID-19 infection. Previous studies conducted among patients with cancer experiencing taste and smell abnormalities have indicated improvement in taste and smell function following daily lactoferrin supplementation. Lactoferrin is a natural transferrin protein that scavenges and chelates iron byproducts produced as a function of lipid oxidation in the oral cavity following inflammation, infection, or toxicity of chemosensory tissues. The purpose of this pilot investigation is to assess the feasibility and preliminary effectiveness of lactoferrin supplementation (750mg per day for 30 days) for the treatment of taste and smell disturbances following COVID-19 infection. Approximately 40 patients who experienced disruptions in taste and smell following infection with COVID-19 will be recruited. Participants will complete baseline assessments (questionnaires, blood draw) and will be given 90 lactoferrin tablets (provided by Jarrow Formulas) in order to take 3 tablets per day for 30 days.
