The Relationship Between the Risk of Aspiration Pneumonia and the Risk of Aspiration: Aspiration Risk and Aspiration Pneumonia Risk Are Not the Same?

Aspiration Pneumonia

Abstract

Reported risks for aspiration include cerebrovascular disease, laryngopharyngeal dysfunction, advanced age, severe dementia, Parkinson’s disease, malnutrition, the use of antipsychotic drugs, and gastroesophageal reflux. Although the aspiration risks may be included among the risks for aspiration pneumonia, the two sets of risks are not identical, and people with aspiration risk factors do not necessarily develop aspiration pneumonia. The risks for aspiration pneumonia also include factors related to the pathogens and to the host defense. Factors associated with the risk of pathogen infection include oral health, such as bacterial colonization and tooth decay, and the use of proton pump inhibitors, and host defense factors associated with the pathogenesis include advanced age, male gender, a preexisting respiratory disease, angiotensin-converting enzyme genotype, malnutrition, diabetes mellitus, and the use of immunosuppressants. Consideration of the relationships between the pathogen, host, and environment is needed for a better understanding of the mechanisms that underlie aspiration pneumonia and for developing effective strategies for its prevention.
