LAS VEGAS – Diabetes and stroke are risk factors for recurrent Clostridium difficile infection (CDI), with stroke patients at about 10 times the risk of recurrence.
The underlying cause for the association is a mystery, but one-sided paralysis is one possibility. “A lot of stroke patients may be hemiplegic, and they may be bedridden, so that may be a risk factor by itself. It’s something that may need to be studied in the future,” Alan Putrus, MD, a gastroenterology fellow at St. John Providence Hospital, Detroit, said in an interview.
CDI recurrence rates range from 5% to 47%, depending on the institution. Although risk factors of initial CDI have been well defined, few studies have looked at risk factors associated with recurrence.
In order to get at the question, the researchers conducted a study of 108 initial CDIs and 113 recurrences at two urban and one suburban hospital. Patients who experienced recurrence were matched 1:1 to age- and gender-matched controls with no recurrent CDI.
CDI recurrence rates were 16.5% and 15.9% in the two urban hospitals, and 14.9% in the suburban hospital.
Logistic regression revealed risk factors associated with CDI recurrence, including diabetes (odds ratio, 1.91; 95% confidence interval, 1.05-3.47; P = .04), stroke (OR, 9.73; 95% CI, 1.15-82.35; P = .04), exposure to proton pump inhibitors in the past 3 months (OR, 1.82; 95% CI, 1.03-3.23; P = .04), and admission to an intensive care unit in the past 3 months (OR, 1.95; 95% CI, 1.0-3.83; P = .04).
The results suggest that diabetes and especially stroke may be important risk factors for CDI recurrence, and their presence should prompt physicians to alter patient care accordingly, according to Dr. Putrus.
He stressed the importance of antibiotic stewardship. “Once you find a certain bug or pathogen, try to deescalate the antibiotics as soon as you can. If a patient is diabetic, controlling their blood sugar may also help,” Dr. Putrus said.
Finally, physicians should consider whether proton pump inhibitors are really necessary. Some patients start on PPIs but remain on the drugs long after symptoms have abated. “A lot of patients just have some discomfort in their abdomen, and they never stop taking it. They keep refilling it. So that’s a problem,” said Dr. Putrus.
Dr. Putrus has declared no conflicts of interest.
