Efficacy and safety of caspofungin in critically ill patients. ProCAS Study.
(57/75)
INTRODUCTION: Caspofungin is an echinocandin with proven efficacy in invasive candidiasis (IC) and invasive aspergillosis (IA). ProCAS is a study sponsored by the Working Group of the Infectious Diseases of the Spanish Society of Intensive Care Medicine, which analyzes the effectiveness and safety of caspofungin in routine clinical practice conditions in the critically ill. METHODS: A prospective, multicenter, observational study designed to estimate the clinical effectiveness and safety of caspofungin acetate in the treatment of IC and IA in patients refractory to or intolerant of conventional antifungal therapy. The assessment of effectiveness both clinic and the microbiological was carried out at the end of the treatment with caspofungin. RESULTS: We included 98 patients, 62 IC proven, 25 probable and 11 IA probable, from 24 centers during 2005 and 2006. Treatment with caspofungin monotherapy was performed in 89.8% of cases and as first line therapy in 54.1%. The favorable clinical response obtained for IC, probable IC, and probable IA was 91.9, 84, and 81.8%, respectively. The microbiological response was favorable in 74.6, 68, and 54.6% for proven cases of IC, probable IC, and probable IA, respectively. No serious adverse effects were observed. CONCLUSIONS: In routine clinical practice conditions, caspofungin is effective and safe for the treatment of invasive fungal infections (IC/IA). The efficacy and safety profile was similar to that observed in published clinical trials. (+info)

Treatment of invasive fungal infections in high risk hematological patients. The outcome with liposomal amphotericin B is not negatively affected by prior administration of mold-active azoles.
(64/75)
There are concerns of a reduced effect of liposomal amphotericin B (L-AmB) given sequentially after mold-active azoles due to a possible antagonism in their antifungal mechanism. To investigate this possible effect in the clinic, we retrospectively studied 182 high risk hematologic patients with invasive fungal infections (IFI) who were treated with L-AmB. Overall, 96 patients (52.7%) had possible, 52 (28.6%) probable and 34 (18.7%) proven IFI according to EORTC classification. Most had suspected or proven invasive aspergillosis. We compared patients with prior exposure to mold-active azoles (n=100) to those having not (n=82). The group with prior mold-active azoles included more patients with poor risk features for IFI as acute myeloid leukemia (p<0.05) and prolonged neutropenia (p<0.05). A favorable response in the IFI, defined as a complete or partial response, was achieved in 75% and 74.4% of patients in the whole cohort, and in 66% and 74.4% of patients with probable or proven IFI in the two groups. None of these differences were significant. Multivariate analysis showed that refractory baseline disease and renal dysfunction were adverse factors for response in the IFI (p<0.05). Survival was poorer for patients with prior broad spectrum azoles (p<0.05), and for those who did not recover from neutropenia (p<0.05). In conclusion, the effectiveness of treatment of breakthrough fungal infection with L-AmB is not likely to be affected by prior exposure to mold-active azoles prophylaxis, but survival largely depends on host and disease factors.
