Assessment of oral health in elderly patients with dementia by measuring volatile sulfur compounds and its relationship with pneumonia development: A pilot study

Background: This study aimed to clarify the involvement of anaerobes in aspiration pneumonia by measuring volatile sulfur compounds (VSCs), which are metabolites of anaerobic bacteria in the mouth. Methods: This study included 84 older adult patients (mean age, 82.5 +/- 7.34 years) who had dementia and were hospitalized for more than 6 months. We measured the VSCs in the patients mouth with Oral Chroma and obtained the data of pneumonia development in the past 6 months. We also evaluated the association or correlation of VSCs and some factors which might be the risk factors of aspiration pneumonia. Results: The development of pneumonia had no significant association with the VSCs in the patient's mouth. Conclusion: The present pilot study suggests that anaerobes might not be the main causative pathogens of aspiration pneumonia in older adult patients. (C) 2021 The Japanese Respiratory Society.
