NCT ID: NCT05760079 Withdrawn - Covid19 Clinical Trials

Lactoferrin for COVID-19-Induced Taste or Smell Abnormality

TSA
Start date: June 2022
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT03043144 Withdrawn - Malnutrition Clinical Trials

Taste And Smell TEsting in End Stage Renal Disease

TASTE ESRD
Start date: February 15, 2017
Phase: N/A
Study type: Observational

Malnutrition is an important complication of advanced kidney disease and impairment in smell and taste may affect nutritional status. This study will examine the association between impairment in smell and taste and nutritional and functional markers among patients with end stage renal disease, as well as risk factors for smell and taste impairment.
