Micafungin for the treatment of proven and suspected invasive candidiasis in children and adults: findings from a multicenter prospective observational study.

Abstract

BACKGROUND:

A multicenter observational study was conducted in Italy to assess the safety of micafungin in the daily clinical practice for the treatment of proven and suspected invasive candidiasis (IC), as well as to describe rates of clinical response to micafungin treatment.

METHODS:

From October 2010 to March 2012, data from consecutive eligible neonate, pediatric, and adult patients treated with micafungin for a proven or suspected IC were collected. Patients were deemed as eligible if they or their parents signed an informed consent. The study endpoints were to assess safety of micafungin in the treatment of both proven and suspected IC, and to describe rates of clinical response to micafungin treatment. Clinical response was assessed at the end of micafungin treatment (EOMT) and defined as favorable (complete or partial resolution of signs and symptoms) or unfavorable (stability or progression).

RESULTS:

During the study period, 108 patients with proven or suspected IC were enrolled. Thirty-six out of 108 patients (33%) were < 18 year-old (median 1 year), whereas 72 (67%) were ≥ 18 year-old (median 71 years). Neonates in NICU accounted for 36% of pediatric patients, with the majority of them (54%) being extremely low birth weight (ELBW) newborns. Fifty-eight out of 108 patients (54%) received micafungin for a proven IC, whereas 50/108 patients (46%) were treated for a suspected IC. Among proven IC, candidemia accounted for the majority of events (54/58, 93%), with Candida albicans (35/58, 60%) as the most frequently isolated species. Therapy was discontinued due to occurrence of an adverse event in 4/108 subjects (4%). No pediatric patient had treatment interruption because of adverse events. A 67% favorable response rate was observed at EOMT. No age-, species-, underlying conditions- or ward-related differences of favorable response were observed. Survival at EOMT was 90% (97/108 patients), with rates of 97% (35/36) and 86% (62/72) among children and adults, respectively.

CONCLUSIONS:

Micafungin was well tolerated in a heterogeneous real world population with a bimodal age distribution. A high rate of favorable response to micafungin treatment was reported in both proven and suspected IC.
