Abstract:The duration of PPI therapy is significantly associated with CDI. Clinicians should strongly consider restricting PPI use given the short exposure time associated with this increased risk.
“…Their high safety, efficacy and wide distribution lead to overuse, inappropriate dosage and excessive durations of treatment. Howell et al [15] reported that increasing levels of pharmacologic acid suppression are associated with increased risks of nosocomial Clostridium difficile (CD) infection and Barletta et al [16] reported that the duration of PPI therapy is significantly associated with CD infection and suggested consideration of restricting PPI use, given the short exposure time. However, more recent studies have offered conflicting viewpoints regarding the association between PPI use and increased risk of CD infection [17][18][19] .…”

Introduction: Clostridium difficile is a common cause of nosocomial diarrhea, especially in elderly patients. This study aimed to analyze the clinical features and assess the risk factors associated with Clostridium difficile infection (CDI) in elderly hospitalized patients. Methodology: A retrospective case-control study was conducted among elderly hospitalized patients (> 60 years of age) in a Chinese tertiary hospital between 2010 and 2013. Fifty-two CDI patients and 150 randomly selected non-CDI patients were included in the study. Clinical features of CDI and non-CDI patients were compared by appropriate statistical tests. Logistic regression analyses were performed on a series of factors to determine the risk factors for CDI among the elderly hospitalized patients. Results: The elderly CDI patients showed higher leukocyte counts, lower serum albumin levels, longer duration of hospital stay, and higher mortality compared to the non-CDI patients. The proportion of patients admitted to the intensive care unit or exposed to gastric acid suppressants was also significantly different (p < 0.05) between the two groups. Multivariate analysis indicated that serum creatinine (OR 1.004; 95% CI 1.001-1.008), surgical intervention (OR 6.132; 95% CI 2.594-14.493), the number of comorbidities (OR 2.573; 95% CI 1.353-4.892), gastrointestinal disease (OR 4.670; 95% CI 2.002-10.895), and antibiotic use (OR 6.718; 95% CI 2.846-15.859) were independently associated with CDI. Conclusions: This study revealed several risk factors for CDI among elderly hospitalized patients. These findings will increase the knowledge concerning this disease and provide information regarding the control and prevention of CDI in the elderly.
“…A few studies reported no increased risk of developing CDI if patients are exposed to a PPI . However, significantly more clinical studies found the use of a PPI among hospitalized patients as a risk factor for the development of CDI …”
Hematologic malignancies and a conditioning regimen administered for HSCT were not significant risk factors for the development of CDI after HSCT. Use of corticosteroids prior to HSCT and use of proton pump inhibitors at the time of HSCT were associated with a significantly decreased risk of CDI.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
