Objectives The incidence of Clostridium difficile infection (CDI) in adults with malignancy is 7%-14% compared with 1%-2% in the general hospitalized population. Despite the increased incidence of CDI in this population, a major concern is the propensity of CDI to recur, leading to delays in therapy impacting outcomes. We conducted a retrospective case-control study to identify risk factors for recurrent CDI (rCDI) and to determine the impact of rCDI on adult patients with a haematological malignancy. Methods Adult haematology patients with CDI from June 2010 to December 2014 were divided into two groups: rCDI and non-rCDI. Multivariable models using logistic regression were constructed to identify risk factors for rCDI. Results A total of 100 patients in our study yielded a 41% recurrence rate. CDI impacted chemotherapy significantly more in the rCDI group (53.7% versus 11.9%, P

Background Despite fungal prophylaxis, invasive mold infections (IMIs) are a significant cause of morbidity and mortality in patients with acute myeloid leukemia (AML) receiving remission induction chemotherapy. The choice of antifungal prophylaxis agent remains controversial, especially in the era of novel targeted therapies. We conducted a retrospective case–control study to determine the incidence of fungal infections and to identify risk factors associated with IMI. Methods Adult patients with AML receiving anti-Aspergillus prophylaxis were included to determine the incidence of IMI per 1000 prophylaxis-days. Patients without and with IMI were matched 2:1 based on the day of IMI diagnosis, and multivariable models using logistic regression were constructed to identify risk factors for IMI. Results Of the 162 included patients, 28 patients had a possible (n = 22), probable, or proven (n = 6) diagnosis of IMI. The incidence of proven or probable IMI per 1000 prophylaxis-days was not statistically different between anti-Aspergillus azoles and micafungin (1.6 vs 5.4, P = .11). The duration of prophylaxis with each agent did not predict IMI occurrence on regression analysis. Older age (odds ratio [OR], 1.04; 95% confidence interval [CI], 1.004–1.081; P = .03) and relapsed/refractory AML diagnosis (OR, 4.44; 95% CI, 1.56–12.64; P = .003) were associated with IMI on multivariable analysis. Conclusions In cases that preclude use of anti-Aspergillus azoles for prophylaxis, micafungin 100 mg once daily may be considered; however, in older patients and those with relapsed/refractory disease, diligent monitoring for IMI is required, irrespective of the agent used for antifungal prophylaxis., The risk for proven or probable breakthrough invasive mold infections (IMI) in acute myeloid leukemia (AML) patients undergoing induction chemotherapy was not different between patients receiving micafungin or anti-aspergillus azoles. Older patients and those with relapsed or refractory AML were at the highest risk of breakthrough IMI.
