The electronic surveillance system Hema e-Chart allowed us to prospectively collect data and to perform an analysis of invasive fungal infections (IFI) diagnosed in febrile patients as well as the procedures allowing their diagnosis and outcome according to the treatment given. Every patient admitted to 26 Italian Haematology Units with a new diagnosis of haematological malignancy and who was a candidate for chemotherapy was consecutively registered between March 2007 and March 2009. In all, 147 haematological patients with mycoses were identified. Yeasts were found in 23 infections; moulds were diagnosed in 17 proven, 35 probable and 72 possible mycoses. Galactomannan (GM) antigen was the most important test to diagnose probable mould infection; it was positive (cut-off >0.5) in 27 (77%) probable and in nine (53%) proven mould infections. Among patients with probable/proven mould infection who received no prophylaxis or non-mould-active prophylaxis with fluconazole, more patients (n = 26, 78.8%) had GM antigen positivity compared with patients (n = 10, 52.6%) given prophylaxis with mould-active drugs (p <0.05). First-line antifungal therapy was effective in 11/23 (48%) yeast infections and in 37/52 (71.2%) proven/probable mould infections. Twenty patients (14%) died within 12 weeks. The fungal attributable mortality was 30.4% and 17.3% in yeast and proven/probable mould infections, respectively. Among risk factors only age was independently associated (p 0.013) with mortality; sex, underlying haematological malignancy, previous prophylaxis and presence of neutropenia at diagnosis were not significant. A diagnosis of mould infection seemed to have a trend for a better outcome than the diagnosis of yeast infection (p 0.064).
电子监测系统 Hema e-Chart 允许我们前瞻性地收集数据,并根据所给予的治疗方法,对发热患者中诊断出的侵袭性真菌感染 (IFI) 以及诊断和预后相关的程序进行分析。2007 年 3 月至 2009 年 3 月,26 家意大利血液学单位连续登记了每一位新诊断为血液恶性肿瘤且适合化疗的入院患者。共发现 147 例血液病患者合并真菌感染。23 例感染中发现酵母菌;17 例确诊、35 例疑似和 72 例可能真菌感染中诊断为霉菌。半乳甘露聚糖 (GM) 抗原是诊断疑似霉菌感染最重要的检查;27 例(77%)疑似霉菌感染和 9 例(53%)确诊霉菌感染 GM 抗原阳性(临界值 >0.5)。在未接受预防治疗或未接受氟康唑非霉菌活性预防治疗的疑似/确诊霉菌感染患者中,GM 抗原阳性的患者(n = 26,78.8%)多于接受霉菌活性药物预防治疗的患者(n = 10,52.6%)(p <0.05)。一线抗真菌治疗对 23 例酵母菌感染中的 11 例(48%)和 52 例确诊/疑似霉菌感染中的 37 例(71.2%)有效。20 例患者(14%)在 12 周内死亡。真菌相关性死亡率在酵母菌感染和确诊/疑似霉菌感染中分别为 30.4%和 17.3%。在所有危险因素中,只有年龄与死亡率独立相关(p 0.013);性别、基础血液恶性肿瘤、既往预防治疗和诊断时中性粒细胞减少无显著相关性。霉菌感染的诊断似乎比酵母菌感染的诊断有更好的预后趋势(p 0.064)。
