8 The Story of de Mrs H In January 27 : She underwent an Allogeneic HSCT from an HLA Identical Unrelated Donor (1/1) after a myeloablative conditioning regimen combining Cyclophosphamide 12 mg/kg and TBI at 12Gy She received a gut decontamination and an antiviral prophylaxis from D-9 to D1

9 Do you prescribe an Antifungal Prophylaxis? 1) No Prophylaxis 2) Yes : - Fluconazole PO Voriconazole PO Ambisome IV Caspofungine IV Posaconazole PO

10 The story of de Mrs H We decided to give : Fluconazole PO 4 mg qd 1

12 The story of de Mrs H She well engrafted without any immediate complication and she discharged on D28 with: - Neoral PO (3 mg/kg/day day) - Fluconazole PO 4mg qd - Oracilline, Valaciclovir and Bactrim At Day 36 she developped an acute GVHD of Grade III that we treated with Methylprednisolone (2 mg/kg/day) with maintenance of Neoral 12

13 Antifungal Prophylaxis Do you maintain Fluconazole? Do you switch? For which molecule?

14 The story of de Mrs H We decided to switch to : Posaconazole PO 2mg TID The evolution of the patient was good without any complications and any breakthrough fungal infections.

26 1st case: Conclusion In acute myelogenous leukemia patients with neutropenia due to chemotherapy, posaconazole was Significantly better than pooled standard azoles for prophylaxis for Candida and Aspergillus infections Associated with a decrease in all cause mortality at day 1 In hematopoietic stem cell transplant recipients with graft versus host disease, posaconazole was Significantly better than fluconazole for prophylaxis for Candida and Aspergillus infections during the exposure period* Associated with a reduction in invasive fungal infection-related mortality Posaconazole has a safety profile comparable to fluconazole *On-treatment period.

27 2nd Case: The story of de Mrs B The similar story in the beginning but patient maintained fluconazole when she developed GVHD At D 7 : she developed a Fever,, a productive cough, a chest pain and she was hospilalized. The leucocyte count showed 118/mm 3 (16 Neutro) GM Antigenemia was positive at a level of 2.9 The Fibrinogen level was 11.7 g/l 27

29 The story of de Mrs B Scanner 29

30 It is a probable Invasive pulmonary Aspergillosis according to the EORTC criteria What do you do? - Complementary exams? - Specific Treatment? 3

31 The story of de Mrs B We do : A Bronchoalveolar Lavage which showed : - Mycellar filaments at the direct exam and culture showed an Aspergillus Fumigatus - BAL : Ag+ 31

32 Diagnosis of Proven Pulmonary Apergillosis Choice of Antifungal Treatment - Voriconazole IV then PO? - Voriconazole PO? - Caspofungine IV? - Ambisome IV? - Posaconazole PO? - Amphotericine B? - Combinations?

33 The story of de Mrs B - It is a proven IFI (IPA) - We decided to give : Ambisome IV

34 Treatment of First Line International Recommendations ECIL 27 - Voriconazole : AI - Ambisome : BI - Combinations : not recommended IDSA 28 - Voriconazole : AI - Ambisome : AI - Combinations : not recommended

35 The story of de Mrs B Ag Evolution of the Scanner over time on Ambisome IV

36 What do you do in front of IFI worsening? - A new monotherapy : - Caspofungine IV? - Voriconazole IV? - Posaconazole PO? - Other monotherapies? - A combination of antifungal molecules?
