RESUMO
The safety and efficacy of micafungin were evaluated in a Japanese post-marketing survey involving 1,142 patients with deep mycosis caused by Candida or Aspergillus. The overall clinical response was 83.0%, and the respective responses for patients with candidiasis or aspergillosis were 86.3 and 70.8%. With regard to drug reactions, 562 adverse reactions were observed in 28.5% of patients. Among the 83 serious adverse drug reactions reported by 53 patients, a causal relationship with micafungin was assessed as definite or probable for 6 reactions in 5 patients. Age and baseline hepatic and renal function status did not affect the incidence of adverse reactions, although incidence increased significantly in proportion to the severity of mycosis and daily dose (p < 0.01). In multiple logistic regression analysis, neither baseline hepatic impairment nor increased daily dose of micafungin affected the incidence of hepatobiliary disorders, however, the severity of mycosis was found to correlate significantly with hepatobiliary disorders (p = 0.031). Taken together, our post-marketing findings show that micafungin is effective against deep mycosis caused by Candida or Aspergillus in patients across a range of backgrounds.
