Liposomal amphotericin B (L-AmB) or micafungin (MCFG) has been widely used as a first-line empirical antifungal therapy for suspected fungal infection in such patients. However, there are several issues in patients receiving these agents: drug related toxicities for L-AmB and breakthrough fungal infections for MCFG. In order to make the best use of these 2 agents, we conducted a prospective study of sequential therapy from MCFG to L-AmB, and evaluated the efficacy and safety of this strategy in FN patients with hematologic malignancies. A total of 18 patients were enrolled, and 11 patients who fulfilled the protocol defined criteria were evaluated. Underlying diseases consisted of acute leukemia (n = 9), non-Hodgkin lymphoma (n = 1), and myelodysplastic syndrome (n = 1). Treatment success was achieved in 8 patients (72.7%). Drug-related adverse events occurred in 8 patients (72.7%). All of those adverse events except one case were below grade 2. Three patients required discontinuation of L-AmB. Although our empirical antifungal sequential therapy seems to be encouraging for antibiotics-refractory FN in patients with hematologic malignancies, further investigation in large-scale studies is warranted.展开更多

It is a life threatening infection causing high mortality. The clinical signs are generally compatible with the causative agent (whether there is a deep venous catheter or not). On the other hand and according to the 2012 Revised Chapel Hill Classification, granulomatosis with polyangiitis GPA is classified as a vasculitis associated with antineutrophil cytoplasmic antibodies ANCA. It is a systemic disease characterized by the anatomopathological aspect of granuloma. We report the case of a patient who presented an atypical and a very rare revealing mode of GPA which was a bronchopulmonary candidiasis complicated by candidemia. Despite its controversy, the combination in the acute phase of antifungal treatment based on intravenous voriconazole and glucocorticoid therapy has made it possible to control candidemia and calm vasculitis.展开更多

A high index of suspicion in the appropriate clinical setting with prompt diagnosis and optimal treatment is recommended. We made a systemic analysis of 82 reported cases in literature in order to improve clinical knowledge of pulmonary mucormycosis. We described a patient with localized pulmonary mucormycosis diagnosed by histological examination in our hospital. Optimal therapy consists of antifungal medication, surgical resection and control of the patient's underlying illness.展开更多
