micafungin and Multiple-Organ-Failure

Although frequently used in treating intensive care unit (ICU) patients with sepsis, empirical antifungal therapy, initiated for suspected fungal infection, has not been shown to improve outcome.. To determine whether empirical micafungin reduces invasive fungal infection (IFI)-free survival at day 28.. Multicenter double-blind placebo-controlled study of 260 nonneutropenic, nontransplanted, critically ill patients with ICU-acquired sepsis, multiple Candida colonization, multiple organ failure, exposed to broad-spectrum antibacterial agents, and enrolled between July 2012 and February 2015 in 19 French ICUs.. Empirical treatment with micafungin (100 mg, once daily, for 14 days) (n = 131) vs placebo (n = 129).. The primary end point was survival without proven IFI 28 days after randomization. Key secondary end points included new proven fungal infections, survival at day 28 and day 90, organ failure, serum (1-3)-β-D-glucan level evolution, and incidence of ventilator-associated bacterial pneumonia.. Among 260 patients (mean age 63 years; 91 [35%] women), 251 (128, micafungin group; 123, placebo group) were included in the modified intent-to-treat analysis. Median values were 8 for Sequential Organ Failure Assessment (SOFA) score, 3 for number of Candida-colonized sites, and 99 pg/mL for level of (1-3)-β-D-glucan. On day 28, there were 82 (68%) patients in the micafungin group vs 79 (60.2%) in the placebo group who were alive and IFI free (hazard ratio [HR], 1.35 [95% CI, 0.87-2.08]). Results were similar among patients with a (1-3)-β-D-glucan level of greater than 80 pg/mL (n = 175; HR, 1.41 [95% CI, 0.85-2.33]). Day-28 IFI-free survival in patients with a high SOFA score (>8) was not significantly different when compared between the micafungin vs placebo groups (HR, 1.69 [95% CI, 0.96-2.94]). Use of empirical micafungin decreased the rate of new invasive fungal infection in 4 of 128 patients (3%) in the micafungin group vs placebo (15/123 patients [12%]) (P = .008).. Among nonneutropenic critically ill patients with ICU-acquired sepsis, Candida species colonization at multiple sites, and multiple organ failure, empirical treatment with micafungin, compared with placebo, did not increase fungal infection-free survival at day 28.. clinicaltrials.gov Idenitfier: NCT01773876.

The potential interest of antifungal treatment of non-immunocompromized patients with sepsis, extra-digestive Candida colonization and multiple organ failure is unknown. It represents three-quarters of antifungals prescribed in Intensive Care Units. It may allow early treatment of invasive fungal infection in the incubation phase but expose patients to unnecessary antifungal treatments with subsequent cost and fungal selection pressure. As early diagnostic tests for invasive candidiasis are still considered to be insufficient, the potential interest in this strategy needs to be demonstrated.. This prospective multicenter, double blind, randomized-controlled trial is conducted in 23 French Intensive Care Units. All adult patients, mechanically ventilated for more than four days with sepsis of unknown origin and with at least one extradigestive fungal colonization site and multiple organ failure are eligible for randomization. Patients with proven invasive candidiasis are not included. After a complete mycological screening, patients are allocated to receive micafungin 100 mg intravenously once a day or placebo for 14 days. We plan to enroll 260 patients. The main objective is to demonstrate that micafungin increases survival of patients without invasive candidiasis at day 28 as compared to placebo. Other outcomes include day 28 and 90 survival and organ failure evolution. Additionally, pharmacokinetics of micafungin in enrolled patients will be measured and evolution of fungal biomarkers and susceptibility profiles of infecting fungi will also be followed.. This study will help to provide guidelines for treating non-immunocompromized patients with fungal colonization multiple organ failure and sepsis of unknown origin..

Echinocandins are first-line therapy in critically ill patients with invasive Candida infection (ICI). This study describes our experience with micafungin at Surgical Critical Care Units (SCCUs).. A multicenter, observational, retrospective study was performed (12 SCCUs) by reviewing all adult patients receiving 100 mg/24h micafungin for ≥72h during ad-mission (April 2011-July 2013). Patients were divided by ICI category (possible, probable + proven), 24h-SOFA (<7, ≥7) and outcome.. 72 patients were included (29 possible, 13 probable, 30 proven ICI). Forty patients (55.6%) presented SOFA ≥7. Up to 78.0% patients were admitted after urgent surgery (64.3% with SOFA <7 vs. 90.3% with SOFA ≥7, p=0.016), and 84.7% presented septic shock. In 66.7% the site of infection was intraabdominal. Forty-nine isolates were recovered (51.0% C. albicans). Treatment was empirical (59.7%), microbiologically directed (19.4%), rescue therapy (15.3%), or anticipated therapy and prophylaxis (2.8% each). Empirical treatment was more frequent (p<0.001) in possible versus probable + proven ICI (86.2% vs. 41.9%). Treatment (median) was longer (p=0.002) in probable + proven versus possible ICI (13.0 vs. 8.0 days). Favorable response was 86.1%, without differences by group. Age, blood Candida isolation, rescue therapy, final MELD value and %MELD variation were significantly higher in patients with non-favorable response. In the multivariate analysis (R2=0.246, p<0.001) non-favorable response was associated with positive %MELD variations (OR=15.445, 95%CI= 2.529-94.308, p=0.003) and blood Candida isolation (OR=11.409, 95%CI=1.843-70.634, p=0.009).. High favorable response was obtained, with blood Candida isolation associated with non-favorable response, in this series with high percentage of patients with intraabdominal ICI, septic shock and microbiological criteria for ICI.

Scedosporium prolificans (S. prolificans) is a type of mold, which rarely affects immunocompromised people. We treated a 71-year-old woman with acute myeloid leukemia (AML-M5a) with low-dose cytarabine, acralubicin, and filgrastim as the induction therapy. On day 7 after the initiation of chemotherapy, she became febrile and agranulocytic, and developed anal pain ; therefore, we discontinued the chemotherapy on day 8. Broad-spectrum antibiotics, micafungin, and then liposomal amphotericin B were ineffective. The serum concentration of β-D-glucan was 525 pg/mL. She died of multiple organ failure on day 17. S. prolificans was detected from the blood culture on day 13. Physicians should consider Scedosporium spp. infection when principal antifungal agents are ineffective and fungal infection is strongly suspected.

Invasive rhinocerebral mucormycosis is a rare and often fatal opportunistic fungal infection. It is encountered in immunocompromised hosts exemplified by those with diabetes, human immunodeficiency viruses and particularly haematologic malignancies typically after high-dose chemotherapy and stem cell transplantation. In contrast to the more usual outcome with rapid progression and death. We now describe a successful eradication attributable to the use of a newly available antifungal agent.. Haematology department and bone marrow transplantation unit.. Two patients are contrasted. The first with acute leukaemia developed rapidly progressive facial swelling with mucormycosis proven on biopsy. Treatment over 2 months with maximally tolerated doses of amphotericin failed to halt intracranial extension and death resulted. The second, presented with acute lymphoblastic leukaemia in August 1997, underwent successful autologous bone marrow transplantation in February 1998. Relapse followed in March 1999 and after reinduction and consolidation receive a matched unrelated volunteer allograft in September 1999. A second recurrence was documented in April 2000 and in spite of achieving remission he developed a fever that was managed empirically with intravenous amphotericin and, on discharge, oral itraconazole. Left-sided facial swelling expanded rapidly and biopsy showed extensive invasion of the maxillary sinus with mucormycosis. FK463 was added on 5 June 2000 with gradual reduction in facial pain and within 1 month all clinical signs and resolved. Serial biopsies that included histopathologic investigation and microbiologic cultures confirmed eradication of the invasive mucor. In view of the potential danger of recrudescence this treatment regimen was continued through further chemotherapy and, once again disease-free, a second matched unrelated volunteer allograft took place in August 2000. Full reassessment at the time failed to demonstration any residual fungus. Engraftment was confirmed but neutropenic sepsis resulted in severe inflammatory response syndrome with progression to multiple organ dysfunction to which he succumbed without any evidence of leukaemic or systemic mycosis.. Echinocandin FK463 is of documented value in managing invasive candidiasis and aspergillosis. This is believed to be the first case of successful outcome with one of the angiotrophic zygomycetes.
