Cognitive and Immunologic Profiles of Patients With Olfactory Dysfunction After Smell Training (CIPOD)
A research study to assess the baseline olfactory function, mental health status, clinical severity, and immunological profile in patients with smell loss. The impact of a 3-month olfactory training program on smell function, immunological changes, and mental health in patients with smell loss will be evaluated.
The primary purpose of this study is to investigate tissue and blood samples to identify molecules that may be related to smell loss, ultimately aiming to develop future treatments for this condition and correlate with cognition.

Interventie / Behandeling
Gedetailleerde beschrijving
Adult patients with chronic rhinosinusitis (CRS) with nasal polyps and those experiencing loss of smell will be recruited for the study, along with healthy control participants. We will exclude individuals with unilateral nasal polyps, autoimmune diseases, ciliary disorders, cystic fibrosis, or smell loss due to tumors or trauma.
Assessments will be conducted at baseline and again three months after smell training to evaluate changes in olfactory function. Control patients will only undergo baseline testing with no follow-up assessments needed.

Maatregel Beschrijving |
Tijdsspanne |
|---|---|---|
|
Primary Outcome Measure 1: Baseline olfactory function measured by UPSIT score
Tijdsspanne: Baseline
|
At baseline, participants will complete the University of Pennsylvania Smell Identification Test (UPSIT), a standardized 40-item scratch-and-sniff odor identification test. Scores range from 0 to 40, with higher scores indicating better olfactory function. Unit of Measure: Score on a scale from 0 to 40. |
Baseline
|
|
Primary Outcome Measure 2: Baseline quality-of-life impact of olfactory dysfunction measured by QOD-NS score
Tijdsspanne: Baseline
|
At baseline, participants will complete the Questionnaire of Olfactory Disorders-Negative Statements (QOD-NS), which measures the negative psychosocial impact of olfactory dysfunction. Scores range from 0 to 48, with higher scores indicating greater negative impact of smell loss on quality of life. Unit of Measure: Score on a scale from 0 to 48. |
Baseline
|
|
Primary Outcome Measure 3: Baseline cognitive function measured by MMSE score
Tijdsspanne: Baseline
|
At baseline, participants will complete the Mini-Mental State Examination (MMSE), an 11-question cognitive screening tool. Scores range from 0 to 30, with higher scores indicating better cognitive function. Unit of Measure: Score on a scale from 0 to 30. |
Baseline
|
|
Primary Outcome Measure 4: Baseline nasal cytokine concentration
Tijdsspanne: Baseline
|
At baseline, nasal secretions will be collected from the middle meatus using a polyvinyl alcohol (PVA) sponge and analyzed for cytokine concentrations by multiplex immunoassay. Each cytokine concentration will be reported separately and will not be combined with questionnaire or cognitive assessment scores. Unit of Measure: pg/mL for each cytokine concentration reported separately. |

|
Change from baseline to Month 3 in olfactory function will be assessed using the University of Pennsylvania Smell Identification Test (UPSIT), a standardized 40-item scratch-and-sniff odor identification test.
Scores range from 0 to 40, with higher scores indicating better olfactory function.
Unit of Measure: Change in score on a scale from 0 to 40.
