Impact of Probiotics on Oral Microbiota in Older Adults With Dysphagia

Status Completed

Clinical Trial Summary

The overall purpose of this study is to characterize the effect of probiotics on the oral microbiota in older adults with dysphagia at risk for pneumonia.

Clinical Trial Description

The goal of this pilot study is to characterize the effects of probiotics on the oral microbiota in older patients with dysphagia at risk for pneumonia. A total of 20 participants will be recruited from the UW Health Inpatient Swallowing Consult Service. Participants will have a dysphagia diagnosis along with documented aspiration on videofluoroscopy. Each participant will receive a once daily VSL#3 probiotic blend (dissolved in thickened liquid as applicable) for 28 days. A baseline assessment will be completed to collect data on demographics, health history and behaviors, usual diet, level of oral intake, and patient-reported swallow function. Oral swab (buccal mucosa and tongue dorsum) as well as saliva sample collections will be completed. Data on adherence and adverse events will be collected weekly. Bacterial DNA will be extracted from oral samples and 16S rRNA sequencing techniques will be used to identify contents of oral microbiota at baseline, week 2, and week 4. Oral microbial composition will be compared between the time points, and treatment feasibility (recruitment and retention rates) in this population will be evaluated. ;
