Background:
Clostridium difficile infection (CDI) recurs in 20-30% of patients.
Aim:
To describe the predictors of recurrence in out-patients with CDI.
Methods:
Out-patient cases of CDI in Olmsted County, MN residents diagnosed between 28 June 2007 and 25 June 2010 were identified. Recurrent CDI was defined as recurrence of diarrhoea with a positive C. difficile PCR test from 15 to 56 days after the initial diagnosis with interim resolution of symptoms. Patients who had two positive tests within 14 days were excluded. Cox proportional hazard models were used to assess the association of clinical variables with time to recurrence of CDI.
Results:
The cohort included 520 out-patients; 104 had recurrent CDI (cumulative incidence of 17.5% by 30 days). Univariate analysis identified increasing age and antibiotic use to be associated with recurrent CDI. Severe CDI, peripheral leucocyte count and change in serum creatinine >1.5-fold were not. In a multiple variable model, concomitant antibiotic use was associated with risk of recurrent CDI (HR = 5.4, 95% CI 1.6-17.5, P = 0.005), while age (HR per 10 year increase = 1.1, 95% CI 0.9-1.3, P = 0.22); peripheral leucocyte count >15 × 10(9) /L (HR = 1.0, 95% CI 0.5-2.1, P = 0.92); and change in serum creatinine greater than 1.5-fold (HR = 0.8, 95% CI 0.4-1.5, P = 0.44) were not.
Conclusions:
Antibiotic use was independently associated with a dramatic risk of recurrent Clostridium difficile infection in an out-patient cohort. It is important to avoid unnecessary systemic antibiotics in patients with Clostridium difficile infection, and patients with ongoing antibiotic use should be monitored closely for recurrent infection.

The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.

Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
