CDI is a common complication in SOTR. Recurrence may occur after treatment of the initial episode. However, the clinical risk factors of the recurrence of CDI in SOTR are not well defined.
SOTR transplanted at our center with Clostridium difficile positive PCR(Cepheid Xpert) from January 2011 to December 2014 were identified from the Clinical Microbiology Laboratory database. Multivariable risk factors analysis was performed using logistic regression. The primary outcome was recurrent CDI within 8 weeks of treatment discontinuation.
200 SOTR were diagnosed with CDIs. The median age of the cohort was 56(range 20 to 81)years and transplant types were kidney (n=65), liver (n=71), lung (n=39), heart (n=14), kidney/pancreas (n=8), liver/kidney (n=2) and heart/lung (n=1). CDI occurred at a median of 235.5 days post-transplant. 81 patients received Metronidazole alone. The primary outcome occurred in 16 %(32/200) patients. Factors predictive of recurrence are shown below
|Non Recurrence N=168||Recurrence N=32|
Univariate p value
|OR(95% CI)||Multivariate p value||OR(95%CI)|
|Recent hospital stay||103(61.3%)||26(81.3%)||0.031||2.73(1.07-7.00)||0.211|
|3rd, 4th generation Cephalosporins||33(19.6%)||12(37.5%)||0.027||2.46(1.09-5.52)||0.210|
. Proton pomp inhibitor(PPI) usage was associated with higher rate of recurrence. Severity of CDI was associated with less rate of recurrence. The use of metronidazole alone in the treatment of CDI was not associated with recurrence. Recurrence was associated with longer duration of hospital stay [30.2(55.6) vs 55.9(61.4) days; p=0.03 ] and higher rate of readmission within 30 days[43(25.6%) vs. 19(59.4%) ;p<0.001].
Our study showed that recurrent CDI occurred in 16% of SOTR. In our multivariate analysis, only PPI usage was a risk factor for recurrence. Also recurrence was associated with longer hospital stay and higher rate of readmission within 30 days.
