Cilostazol is Effective to Prevent Stroke-Associated Pneumonia in Patients Receiving Tube Feeding.

Stroke-associated pneumonia (SAP) is a frequent complication in acute ischemic stroke (IS) patients, especially those receiving tube feeding (TF). In this retrospective study, we investigated whether or not cilostazol, a pluripotent phosphodiesterase III-specific inhibitor with anti-platelet and vasculogenic effects, can prevent SAP in these patients and reduce their duration of stay in intensive care unit/hospitalization. We recruited 158 IS patients receiving TF. Patients' characteristics (including age, gender, past history), National Institute of Health Stroke Scale and serum albumin level on admission, concomitant medications associated with SAP prevention (including cilostazol), and stroke characteristics (bilateral subcortical white matter lesion, brainstem involvement, large infarction, and asymptomatic hemorrhagic infarction) were compared between the SAP(-) and SAP(+) groups. Cilostazol was more frequently used in the SAP(-) group (20.8% vs. 6.1%, p < 0.05). Duration of intensive care unit was longer in patients with SAP (9 ± 8 vs. 6 ± 6 days, p < 0.05). However, the length of stay in an intensive care unit and duration of hospitalization were not reduced due to the prevention of SAP by cilostazol treatment. Cilostazol administration was associated with reduced SAP incidence in acute IS patients receiving TF.
