Recomendaciones de un panel de expertos sobre la utilidad de fidaxomicina para el tratamiento de las infecciones causadas por Clostridium difficile

INTRODUCTION: Clostridium difficile infections have a high recurrence rate, which can complicate the prognosis of affected patients. It is therefore important to establish an early detection and an appropriate therapeutic strategy. The objective of this manuscript was to gather the opinion of an expert group about the predictive factors of poor progression, as well as when to use fidaxomicin in different groups of high-risk patients. METHODS: A scientific committee of three experts in infectious diseases reviewed the most recent literature on the management of C. difficile infections, and the use of fidaxomicin. They developed a questionnaire of 23 items for consensus by 15 specialists in this type of infection using a modified Delphi method. RESULTS: The consensus reached by the panelists was 91.3% in terms of agreement. The most important agreements were: recurrence is a risk criterion per se; fidaxomicin is effective and safe for the treatment of infections caused by C. difficile in critical patients, immunosuppressed patients, or patients with chronic renal failure; fidaxomicin is recommended from the first episode of infection to ensure maximum efficacy in patients with well-contrasted recurrence risk factors. CONCLUSIONS: The experts consulted showed a high degree of agreement on topics related to the selection of patients with poorer prognosis, as well as on the use of fidaxomicin in groups of high-risk patients, either in the first line or in situations of recurrence.
