There is no assessment of the reporting quality of antifungal randomized, controlled trials (RCT), upon which guidelines for the treatment of invasive aspergillosis (IA) in patients with hematological malignancy are based. Trial reports were identified through Trip, Cochrane, Medline, and Embase database searches. Report quality was assessed using the 25-item CONSORT checklist and a rating scale of 1 (strongly disagree) to 4 (strongly agree). The primary endpoint was quality as assessed by mean group-scores among papers published at the time of the most recent IA treatment guidelines...

Candida species are regular commensal in humans, but-especially in immunocompromised patients-they represent opportunistic pathogens giving rise to systemic infection. The aim of the present work was to isolate and characterize for their antifungal profile Candida species from different body sites and to analyze the biofilms produced by C. albicans and C. glabrata isolates. Eighty-one strains of Candida species from 77 patients were identified. Epidemiological study showed that the most isolated species were C...

Patients with hematological cancer have a high risk of invasive fungal diseases (IFDs). These infections are mostly life threatening and an early diagnosis and initiation of appropriate antifungal therapy are essential for the clinical outcome. Most commonly, Aspergillus and Candida species are involved. However, other non-Aspergillus molds are increasingly be identified in cases of documented IFDs. Important risk factors are long lasting granulocytopenia with neutrophil counts below 500/μl for more than 10 days or graft-versus-host disease resulting from allogeneic stem-cell transplantation...

The risk of invasive fungal infections (IFIs) is extremely high in patients with hematological malignancies due to the prolonged and profound neutropenia and immunosuppression after chemotherapy and hematopoietic stem cell transplantation. There has been increasing interest in mucormycosis despite its relatively uncommon occurrence, because occasional breakthrough infections have been observed under anti-aspergillus prophylaxis. The aggressive nature of mucormycosis easily leads to high mortality because of delays in diagnosis and incorrect treatment decisions, which are due in part to lack of adjunctive diagnostic tools and having similar clinical and radiological features with aspergillosis...

The incidence of life threatening invasive fungal infections in patients with hematological malignancies during intensive chemotherapy or after hematopoetic stem cell transplantation, patients after solid organ transplantation, ICU patients and premature infants is rising. Mortality rates of invasive fungal infections, caused by Aspergillus species or mucormycetes, may reach 100%, in spite of considerable progress in diagnosis, antifungal prophylaxis and therapy. Comprehensive, profound knowledge of specific diagnostic and current treatment algorithms is essential to improve the prognosis of patients suffering from systemic fungal infections; this article encompasses recent developments in the field of antifungal treatment...

The diagnosis of invasive fungal diseases (IFD) based on clinical, radiological, and conventional microbiological findings is not reliable and is often delayed. Non-culture-based methods with higher sensitivity and specificity may reduce diagnostic time and result in decreased IFD morbidity and mortality. These methods are now increasingly used to manage patients at risk of IFD. Among available biomarkers, fungal antigens have been investigated as an aid to early diagnosis and are predominantly used as screening tests to prompt antifungal treatment mainly in patients with hematological malignancies...

Invasive fungal diseases are major complications associated with the treatment of hematologic malignancies. The integration of host-derived biomarkers into clinical processes to predict the risk and progression of fungal disease is a promising approach in immunocompromised patients. Recent insights into human antifungal immunity have highlighted the remarkable influence of host genetics in modulating susceptibility to infection. In this chapter, we describe protocols to examine human genetic variation and to assess its functional consequences using the pattern recognition receptor PTX3 as an example...

Invasive fungal diseases (IFDs) are a major cause of morbidity and mortality in immunocompromised patients such as patients with hematological malignancies or allogeneic hematopoietic stem cell transplant recipients. Whereas the definite diagnosis of IFD requires invasive diagnostic procedures, imaging and noninvasive diagnostic assays may help in decision making with regard to the institution and the choice of antifungal agents, the duration of therapy, surgical intervention, and monitoring of fungal manifestations...

Hepatosplenic candidiasis also known as chronic disseminated candidiasis is a rare manifestation of invasive fungal infection typically observed in patients with acute leukemia in prolonged, deep neutropenia. Immune reconstitution inflammatory syndrome (IRIS) is an inflammatory disorder triggered by rapid resolution of neutropenia. Diagnosis and treatment of IRIS are still challenging due to a variety of clinical symptoms, lack of certain diagnostic criteria, and no standards of treatment. The diagnosis of IRIS is even more difficult in patients with hematological malignancies complicated by "probable" invasive fungal infection, when fungal pathogen is still uncertain...

In recent years galactomannan antigen testing (GM) and also Aspergillus PCR have become increasingly important for diagnosis of invasive aspergillosis (IA). Whether or not these tests need to be performed with bronchoalveolar lavage fluid (BALF; i.e., primary site of infection), or testing of blood samples is sufficient, remains, however, a matter of debate. We evaluated the diagnostic performance of GM ELISA, and Aspergillus PCR by using BALF samples and blood samples obtained at the same day from a total of 53 immunocompromised patients (16 with probable/proven IA and 37 with no evidence of IA according to the revised EORTC/MSG criteria; 38 patients with hematological malignancies were prospectively enrolled at the Medical University of Graz, Austria, 15 patients with mixed underlying diseases at the Mannheim University Hospital)...

Invasive fungal infection (IFI) is a major life-threatening problem encountered by patients with hematological malignancies receiving intensive chemotherapy. Empirical antifungal agents are therefore important. Despite the availability of antifungal agents for such situations, the optimal agents and administration methods remain unclear. We conducted a prospective phase 2 study of empirical 1 mg/kg/day liposomal amphotericin B (L-AMB) in 80 patients receiving intensive chemotherapy for hematological malignancies...

Invasive fungal infections (IFIs) are an important cause of morbidity and mortality in immunocompromised patients. Patients with hematological malignancies undergoing conventional chemotherapy, autologous or allogeneic hematopoietic stem cell transplantation are considered at high risk, and Aspergillus spp. represents the most frequently isolated micro-organisms. In the last years, attention has also been focused on other rare molds (e.g., Zygomycetes, Fusarium spp.) responsible for devastating clinical manifestations...
