micafungin and Liver-Neoplasms

There is limited information regarding antifungal-induced liver injuries, which have high mortality rates. Therefore, we used the Japanese Adverse Drug Event Report (JADER) database for signal detection associated with antifungal-induced liver injuries and medical records for risk assessment.. Reports of antifungal-induced liver injuries from JADER data were analyzed to calculate the reporting odds ratio (ROR) and 95% confidence interval (CI). A medical record-based study involving 109 adult patients treated with micafungin shows liver injury as the primary outcome in patients treated with micafungin. The albumin-bilirubin (ALBI) score was calculated based on albumin and total bilirubin levels. We selected five explanatory factors for multivariable logistic regression: alanine aminotransferase ≥20 IU/L, alkaline phosphatase ≥372 IU/L, aspartate aminotransferase ≥25 IU/L, ALBI score ≥ -1.290, and age ≥65 years.. Signal detection for micafungin was observed in both, hepatocellular and cholestatic injuries, as per data from JADER. Univariate analyses performed on medical records suggest that alanine aminotransferase (p = 0.008), aspartate aminotransferase (p = 0.036), alkaline phosphatase (p = 0.045), and ALBI score (p = 0.028) may be factors associated with micafungin-induced liver injury. Based on multivariable logistic regression, the adjusted odds ratio for micafungin-induced liver injury in patients with ALBI score ≥ -1.290 was 2.78 (95% CI: 1.014-7.605, p = 0.047), suggesting that low hepatic functional reserve could be a risk factor for micafungin-induced liver injury.. Careful monitoring of liver function may be necessary for micafungin administration in patients with low hepatic functional reserve.

Liver tumours observed in rats exposed to micafungin led to a black box warning upon approval in Europe in 2008. Micafungin's risk for liver carcinogenicity in humans has not been investigated. We sought to describe the risk of fatal hepatocellular carcinoma (HCC) among persons who received micafungin and other parenteral antifungals (PAFs) with up to 12 years of follow-up.. We assembled a US multicentre cohort of hospitalized patients who received micafungin or other PAFs between 2005 and 2012. We used propensity score (PS) matching on patient characteristics from electronic medical records to compare rates of HCC mortality identified through the National Death Index though to the end of December 2016. We computed HRs and 95% CIs.. A total of 40110 patients who received a PAF were identified; 6903 micafungin recipients (87% of those identified) were successfully matched to 16317 comparator PAF users. Ten incident HCC deaths, one in the micafungin-exposed group and nine among comparator PAF users, occurred in 71285 person-years of follow-up. The HCC mortality rate was 0.05 per 1000 person-years in micafungin patients and 0.17 per 1000 person-years in comparator PAF patients. The PS-matched HR for micafungin versus comparator PAF was 0.29 (95% CI 0.04-2.24).. Both micafungin and comparator PAFs were associated with HCC mortality rates of <0.2 per 1000 person-years. Given the very low event rates, any potential risk for HCC should not play a role in clinical decisions regarding treatment with micafungin or other PAFs investigated in this study.
