Item Open Access A Trial of Itraconazole or Amphotericin B for HIV-Associated Talaromycosis.(N Engl J Med, 2018-03-16) Le, Thuy; Kinh, Nguyen Van; Cuc, Ngo TK; Tung, Nguyen LN; Lam, Nguyen T; Thuy, Pham TT; Cuong, Do D; Phuc, Pham TH; Vinh, Vu H; Hanh, Doan TH; Tam, Vu Van; Thanh, Nguyen T; Thuy, Tran P; Hang, Nguyen T; Long, Hoang B; Nhan, Ho T; Wertheim, Heiman FL; Merson, Laura; Shikuma, Cecilia; Day, Jeremy N; Chau, Nguyen VV; Farrar, Jeremy; Thwaites, Guy; Wolbers, Marcel; IVAP InvestigatorsBACKGROUND: Talaromyces marneffei infection is a major cause of human immunodeficiency virus (HIV)-related death in South and Southeast Asia. Guidelines recommend initial treatment with amphotericin B deoxycholate, but this drug has substantial side effects, a high cost, and limited availability. Itraconazole is available in oral form, is associated with fewer unacceptable side effects than amphotericin, and is widely used in place of amphotericin; however, clinical trials comparing these two treatments are lacking. METHODS: In this open-label, noninferiority trial, we randomly assigned 440 HIV-infected adults who had talaromycosis, confirmed by either microscopy or culture, to receive either intravenous amphotericin B deoxycholate (amphotericin) (219 patients), at a dose of 0.7 to 1.0 mg per kilogram of body weight per day, or itraconazole capsules (221 patients), at a dose of 600 mg per day for 3 days, followed by 400 mg per day, for 11 days; thereafter, all the patients received maintenance therapy with itraconazole. The primary outcome was all-cause mortality at week 2. Secondary outcomes included all-cause mortality at week 24, the time to clinical resolution of talaromycosis, early fungicidal activity, relapse of talaromycosis, development of the immune reconstitution inflammatory syndrome (IRIS), and the side-effect profile. RESULTS: The risk of death at week 2 was 6.5% in the amphotericin group and 7.4% in the itraconazole group (absolute risk difference, 0.9 percentage points; 95% confidence interval [CI], -3.9 to 5.6; P<0.001 for noninferiority); however, the risk of death at week 24 was 11.3% in the amphotericin group and 21.0% in the itraconazole group (absolute risk difference, 9.7 percentage points; 95% CI, 2.8 to 16.6; P=0.006). Treatment with amphotericin was associated with significantly faster clinical resolution and fungal clearance and significantly lower rates of relapse and IRIS than itraconazole. The patients who received amphotericin had significantly higher rates of infusion-related reactions, renal failure, hypokalemia, hypomagnesemia, and anemia than patients in the itraconazole group. CONCLUSIONS: Amphotericin was superior to itraconazole as initial treatment for talaromycosis with respect to 6-month mortality, clinical response, and fungicidal activity.

Itraconazole poorly penetrates the central nervous system, whereas fluconazole has poor activity against P. marneffei. We prospectively report management of 1 patient and retrospectively review 7 coinfection cases from Vietnam.Item Open Access Do high MICs predict the outcome in invasive fusariosis?(The Journal of antimicrobial chemotherapy, 2021-03) Nucci, Marcio; Jenks, Jeffrey; Thompson, George R; Hoenigl, Martin; Dos Santos, Marielle Camargo; Forghieri, Fabio; Rico, Juan Carlos; Bonuomo, Valentina; López-Soria, Leyre; Lass-Flörl, Cornelia; Candoni, Anna; Garcia-Vidal, Carolina; Cattaneo, Chiara; Buil, Jochem; Rabagliati, Ricardo; Roiz, Maria Pia; Gudiol, Carlota; Fracchiolla, Nicola; Campos-Herrero, Maria Isolina; Delia, Mario; Farina, Francesca; Fortun, Jesus; Nadali, Gianpaolo; Sastre, Enric; Colombo, Arnaldo L; Pérez Nadales, Elena; Alastruey-Izquierdo, Ana; Pagano, LivioBackground
Invasive fusariosis (IF) affects mostly severely immunocompromised hosts and is associated with poor outcome. Since Fusarium species exhibit high MICs for most antifungal agents, this could explain the poor prognosis. However, a clear-cut correlation between MIC and outcome has not been established.Objective
To evaluate the correlation between MIC and outcome (6 week death rate) in patients with IF.Methods
We performed a multicentre retrospective study of patients with IF who received treatment and had MIC levels determined by EUCAST or CLSI for the drug(s) used during treatment. We compared the MIC50 and MIC distribution among survivors and patients who died within 6 weeks from the diagnosis of IF.Results
Among 88 patients with IF, 74 had haematological diseases. Primary treatment was monotherapy in 52 patients (voriconazole in 27) and combination therapy in 36 patients (liposomal amphotericin B + voriconazole in 23). The MIC50 and range for the five most frequent agents tested were: voriconazole 8 mg/L (range 0.5-64), amphotericin B 2 mg/L (range 0.25-64), posaconazole 16 mg/L (range 0.5-64), itraconazole 32 mg/L (range 4-64), and isavuconazole 32 mg/L (range 8-64). There was no difference in MIC50 and MIC distribution among survivors and patients who died. By contrast, persistent neutropenia and receipt of corticosteroids were strong predictors of 6 week mortality.Conclusions
Our study did not show any correlation between MIC and mortality at 6 weeks in patients with IF.Item Open Access Itraconazole or Amphotericin B for Talaromycosis.(The New England journal of medicine, 2017-10) Brüggemann, Roger J; van de Veerdonk, Frank L; Verweij, Paul E
