[Combination therapy for invasive aspergillosis].

Abstract

The frequency of invasive fungal infections, and specifically invasive aspergillosis, has increased in the last few decades. Despite the development of new antifungal agents, these infections are associated with high mortality, ranging from 40% to 80%, depending on the patient and the localization of the infection. To reduce these figures, several therapeutic strategies have been proposed, including combination therapy. Most of the available data on the efficacy of these combinations are from experimental models, in vitro data and retrospective observational studies or studies with a small number of patients that have included both patients in first-line treatment and those receiving rescue therapy; in addition there are many patients with possible forms of aspergillosis and few with demonstrated or probable forms. To date, there is no evidence that combination therapy has significantly higher efficacy than monotherapy; however, combination therapy could be indicated in severe forms of aspergillosis, or forms with central nervous involvement or extensive pulmonary involvement with respiratory insufficiency, etc. Among the combinations, the association of an echinocandin--the group that includes micafungin--with voriconazole or liposomal amphotericin B seems to show synergy. These combinations are those most extensively studied in clinical trials and therefore, although the grade of evidence is low, are recommended by the various scientific societies.
