[PMID: 35146837 DOI: 10.1111/ped.15033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2021] [Revised: 08/30/2021] [Accepted: 10/13/2021] [Indexed: 11/28/2022]
Abstract
BACKGROUND Candida urinary tract infections (UTIs) are common nosocomial infections among critically ill patients hospitalized in pediatric intensive care Units (PICU). We aimed to report outcomes of critically ill pediatric patients who received micafungin for hospital acquired Candida UTIs. We analyzed treatment success rates and success rates among different Candida species. METHODS This retrospective cohort study included patients who received micafungin for Candida UTI as first choice in our PICU between January 2017 and July 2018. Data, including demographic and clinical features, were retrospectively collected from medical files of the patients. Treatment efficacy was defined as resolution of clinical symptoms and a negative culture for Candida at day 14 after initiation of micafungin treatment. RESULTS Twenty-four pediatric patients (median age 5.72 years, range, 2 months-16 years) were included in the present study. Fourteen (58.3%) patients had urinary catheters at the time of Candida isolation. Resolution of symptoms and a negative culture at day 3 of micafungin treatment were achieved in 17 (70.8%) and 14 (58.3%) patients, respectively. Moreover, 19 (79.2%) patients had a normal urine analysis and negative culture 14 days after initiation of micafungin treatment. Treatment responses did not statistically differ between Candida species. CONCLUSIONS Micafungin is safe and efficacious in critically ill pediatric patients with Candida UTIs. Its efficacy in our pediatric population was as comparable to that observed in adult studies, therefore, it should be considered as an effective therapeutic option in Candida UTIs of critically ill pediatric patients.

Abstract
BACKGROUND Invasive fungal infections are responsible for significant morbidity and mortality. Safety and effectiveness of antifungal agents is a particular concern in pediatric populations, where data are often limited. Micafungin is an echinocandin with demonstrated antifungal activity against a wide spectrum of Candida spp.; this subanalysis of data from the MYRIADE study describes the use of micafungin and its therapeutic outcomes in pediatric patients, in normal clinical practice. METHODS MYRIADE was an observational, multicenter, national, prospective, longitudinal study conducted from January 2010 to December 2012, in patients treated with micafungin using a prophylactic or curative strategy, across 17 sites [oncohematology (n = 8), neonatal intensive care units (ICUs) (n = 5) and pediatric ICUs (n = 4)]. The treatment regimen, the achievement of the therapeutic objective and the tolerance were reported. RESULTS The study population consisted of 110 pediatric patients (31 neonates, 24 children <2 years old and 55 children ≥2 to <16 years old). The therapeutic objective was achieved in 49/64 (76.6%) oncohematology patients, 28/29 (96.6%) neonatal ICU patients and 12/14 (85.7%) pediatric ICU patients. Twenty-four (21.8%) children developed an adverse event (AE); more AEs were observed in oncohematology patients compared with ICU patients [17 (26.1%) vs. 7 (15.6%)]. Only one serious AE, reported in an oncohematology patient, was considered related to micafungin. CONCLUSIONS In the first large observational study of micafungin treatment or prophylaxis conducted under real-world conditions in France, micafungin was effective and well tolerated for prophylaxis of invasive fungal infections in pediatric oncohematology patients and for curative purposes in pediatric and neonatal ICU patients.

Abstract
OBJECTIVE The aim of this meta-analysis was to assess the efficacy and safety of treatment with echinocandins compared with amphotericin B in paediatric patients with invasive candidiasis. METHODS PubMed, Embase and Cochrane databases were searched up to August 2018. Only randomized controlled trials (RCTs) evaluating echinocandins and amphotericin B in the treatment of paediatric patients with invasive candidiasis were included. The outcomes were clinical responses and adverse effects. RESULTS Five RCTs of 354 patients (191 patients in the echinocandins group and 163 patients in the amphotericin B group) were included in this study. Overall, no significant differences in clinical response were found between echinocandins and amphotericin B (odds ratio [OR], 1.38; 95% confidence interval [CI], 0.68-2.80; I2 = 39%). Similar results were also observed in the high-risk group (OR, 3.10; 95% CI, 0.10-97.23; I2 = 76%), the low-risk group (OR, 1.29; 95% CI, 0.36-4.62; I2 = 21%) and the neutropenia group (OR, 1.56; 95% CI, 0.75-3.26; I2 = 0%). The risk of discontinuing treatment because of adverse effects was significantly lower in the echinocandins group than in the amphotericin B group (OR, 0.30, 95% CI, 0.12-0.76; I2 = 0%). CONCLUSIONS There were no differences in efficacy between the echinocandins group and the amphotericin B group in the treatment of invasive candidiasis in paediatric patients. However, the echinocandins group had a significantly lower risk of discontinuing treatment than the amphotericin B group.

Abstract
Micafungin is used off-label in the United States to treat invasive candidiasis in neonates. We used an established pharmacokinetic model to determine micafungin exposures for 46 courses in 39 hospitalized infants. In this small cohort of infants, micafungin exposure was not associated with laboratory markers of liver toxicity, death or failure of microbiologic clearance.

Abstract
BACKGROUND Amphotericin B deoxycholate (AmB-D) is standard of care treatment for neonatal invasive candidiasis (IC). Micafungin (MCA) has broad-spectrum fungicidal activity against Candida spp. We compared the efficacy and safety of intravenous MCA with intravenous AmB-D and assessed the pharmacokinetics of MCA in infants >2-120 days of age with proven IC in a phase 3, randomized, double-blind, multicenter, parallel-group, noninferiority study (NCT00815516). METHODS Infants were randomized 2:1 to MCA (10 mg/kg/d) or AmB-D (1 mg/kg/d) for ≥21 days. Primary efficacy endpoint was fungal-free survival (FFS) 1 week after last study drug dose. MCA population pharmacokinetics included simulated area under the curve (AUC) at steady state and maximum plasma concentration after 2-hour infusion. AUC pharmacodynamic target exposure was 170 µg·h/mL. RESULTS Thirty infants received MCA (n = 20) or AmB-D (n = 10). The trial was terminated early because of slow recruitment. FFS was observed in 12 of 20 [60%; 95% confidence interval (CI): 36%-81%] MCA-group infants and in 7 of 10 (70%; 95% CI: 35%-93%) AmB-D-group infants. The most common treatment-emergent adverse events were anemia [MCA: n = 9 (45%); AmB-D: n = 3 (30%)] and thrombocytopenia [n = 2 (10%) and n = 3 (30%), respectively]. Model-derived mean AUC at steady state for MCA was 399.3 ± 163.9 µg·h/mL (95% prediction interval: 190.3-742.3 µg/mL); steady state and maximum plasma concentration after 2-hour infusion was 31.1 ± 10.5 µg/mL (95% prediction interval: 17.0-49.7 µg/mL). MCA exposures were above the AUC pharmacodynamic target exposure. CONCLUSIONS Within the study limitations, infants with IC treated with MCA achieved similar FFS compared with AmB-D. Both agents were safe and well tolerated.

Abstract
Candidiases are the most recurrent fungal infections, especially among immunosuppressed patients. Although Candida albicans is still the most widespread isolated species, non-Candida albicans Candida species have been increasing. The goal of this work was to determine the susceptibility of C. glabrata biofilms to echinocandins and to evaluate their effect on the biofilm matrix composition, comparing the results with other Candida species. Drug susceptibilities were assessed through the determination of minimum inhibitory concentration (MIC), minimum fungicidal concentration (MFC) and minimum biofilm eradication concentration (MBEC) of caspofungin (Csf) and micafugin (Mcf). The β-1,3 glucans content of the matrices was assessed after contact with the drugs. The data suggest that, generally, after contact with echinocandins, the concentration of β-1,3 glucans increased. These adjustments in the matrix composition of C. glabrata biofilms and the chemical differences between Csf and Mcf, seem responsible and may determine the effectivity of the drug responses.

Abstract
INTRODUCTION The high morbidity and mortality associated with invasive fungal infections (IFIs) provide the rationale for antifungal prophylaxis in immuno-compromised pediatric patients undergoing hematopoietic stem cell transplantation (HSCT). Caspofungin and micafungin are antifungal agents of interest for prophylaxis of IFIs because of their potency against Candida and minimal toxicity or interactions with other drugs. Few studies have demonstrated the safety and efficacy of such echinocandins as prophylaxis for IFIs in patients undergoing HSCT. METHODS This retrospective cohort study compared caspofungin and micafungin for prevention of IFIs in 93 pediatric patients undergoing HSCT for oncological or non-oncological disease. The observation began with the first dose of antifungal agent and ended 3 months after transplantation. RESULTS Patients in the micafungin group had a higher overall treatment success rate of 87.2 versus 84.8% in the caspofungin group, but the difference was not significant. There were no statistically significant differences in the incidence or type of proven/probable IFIs between the 2 groups. The low incidence of death did not differ statistically between the groups. Patients in the caspofungin group presented more frequently with fever, during and after neutropenia. In both groups, we observed an expected worsening of blood chemistry parameters. There were no adverse events definitely attributable to the two antifungal agents. CONCLUSION These results demonstrate good efficacy and tolerability for caspofungin and micafungin. However, better results with respect to the incidence and resolution of fever in the micafungin group may suggest its use in preference to that of caspofungin.

Abstract
Intravenous micafungin (Mycamine®; Funguard®), an echinocandin, is approved in the EU for the treatment of invasive candidiasis in children (including neonates) and adolescents (<16 years of age) and as prophylaxis against Candida infections in patients undergoing haematopoietic stem cell transplantation (HSCT) or who are expected to have neutropenia for ≥10 days. This narrative review focuses on the use of micafungin in paediatric indications approved in the EU, which may vary from those approved elsewhere in the world. Micafungin has a broad spectrum of in vitro activity against clinically relevant isolates of Candida spp. (including fluconazole-resistant Candida glabrata isolates), a low propensity for emergence of resistant isolates and a convenient once-daily regimen. In paediatric substudies and a small multinational, phase 3 trial in neonates with proven invasive candidiasis, intravenous micafungin was effective and generally well tolerated in the treatment of candidaemia and other types of invasive candidiasis and as prophylaxis against fungal infections in patients undergoing HSCT. Hence, micafungin remains an important option for the prophylaxis and treatment of invasive Candida infections in paediatric and adult patients.
