An observational study in Legionnaires' Disease, sponsored by University of Pennsylvania. Completed at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2024-07-24.
Sponsored by University of Pennsylvania · Observational
The goal of this study is to determine whether survivors of Legionnaires' disease suffer smell loss. A quantitative olfactory test will be performed by the participants. Such testing will require approximately 20-30 minutes of the participant's time. The participants will take the University of Pennsylvania Smell Identification Test (UPSIT), a scratch-and-sniff test to assess their ability to identify odors in a forced- choice format. Volunteers will also complete a questionnaire asking personal history, demographic questions, and medical history.
The subjects to be tested in this study represent two different populations. The first is a group of who have survived Legionnaires' disease. The second group will be healthy men and women over the age of 18 years.
Exclusion Criteria:
Volunteers who have been diagnosed/survivors of Legionnaire's Disease
Other: The University of Pennsylvania Smell Identification Test (UPSIT)
Volunteers who are healthy.
Other: The University of Pennsylvania Smell Identification Test (UPSIT)
This standardized test, the most widely used olfactory test in the world, is derived from basic psychological test measurement theory and focuses on the comparative ability of subjects to identify odorants at the suprathreshold level. The UPSIT consists of four envelope-sized booklets, each containing ten "scratch and sniff" odorants embedded in 10- 50-µm polymer microcapsules positioned on brown strips at the bottom of the pages of the booklets.
Score on the University of Pennsylvania Smell Identification Test
The number of correct odor identification responses out of 40 from the standardized University of Pennsylvania Smell Identification Test. The total number of correct responses will then be compared to standard norms of correct responses based on demographic information such as age and sex. Comparing the scores to the standard norms collected will indicate whether a volunteer is normosmic, hyposmic, or anosmic.
Time frame: 20-30 Minutes
Questionnaire Responses
These are various demographic and medical history questions regarding exposure to Legionella Pneumonia and current experiences post diagnosis and treatment.
Time frame: 20-30 Minutes
