[The role of measuring galactomannan in the modern therapy of invasive aspergillosis]

SINKÓ János

[Invasive aspergillosis is a life threatening mycosis prevalent in groups of patients with specific risk factors. To establish the diagnosis a specimen for histological examination has to be obtained. However, the vast majority of patients are not suitable for biopsy or this procedure can only be performed late in the course of the disease. Current diagnostic workup is based on high resolution thoracic CT scans and serum galactomannan antigen testing. Antigen detection can either be used for screening to detect early phase infection or to prove the full-blown disease. Here clinical aspects of galactomannan antigen testing and its role in current management of aspergillosis are reviewed.]

[Empirical versus preemptive antifungal therapy of invasive fungal infections in patients with oncohaematological diseases]

RÓKUSZ László

[Fungal infections present a significant problem among immunocompromised patients. The essence of empirical antifungal therapy is to collect data, physical signs and symptoms that confirm the clinically suspected invasive fungal infections and enable initiation of antifungal therapy. With the improvement of early diagnosis of invasive fungal infactions, the diagnosisdrived application of antifungal preparations has been re-evaluated. However, no consensus exists to date regarding preemptive antifungal therapy. After evaluating the benefits and potential side effects of the therapy, the relevant centers decide whether the preemptive or the empirical method should be preferred.]

[Treatment of invasive fungal infections: present and future]

SINKÓ János

[In immunocompromised patients morbidity and mortality caused by invasive fungal infections is increasing. It is difficult to establish early diagnosis of mycosis by laboratory tests currently available. Antifungal drugs are often toxic, their spectrum of action is limited and their cost is substantial. In the search for alternative therapeutic modalities, antifungal compounds were synthesised against several targets of the fungal cell. At present, the following drugs have almost completed drug registration procedures: voriconazole, posaconazole and ravuconazole from the new azol group, a candin named caspofungin, and the polyene liposomal nystatin. Nikkomycin Z, sordarins and some other compounds are also seem to be promising. In addition to new antifungal drugs, substantial improvement in the outcome of invasive fungal infections requires extended diagnostic capabilities, as well as a reappraisal of our principles of prophylaxis and treatment.]

[Pulmonary abnormalities in haematological malignancies - The role of imaging in differential]

GYŐRI Gabriella, MAGYAR Péter, KOVÁCS Balázs, BÉRCZI Viktor, BALASSA Katalin, DEMETER Judit

[Patients with hematological malignancies may develop a wide range of pulmonary abnormalities due to the hematological disease itself as well as in response to therapy. Immunosuppression and intensive chemotherapy induced severe neutropenia hold a high risk of infection. Infectionrelated morbidity and mortality are still high. One of the most common infectious complications is invasive mycosis, which is lethal in a high percentage of cases if not treated immediately and adequately. Non-infectious complications, such as secondary pulmonary lymphoma, thromboembolism, hemorrhage or drug induced fibrosis may develop during the course of the disease. Sometimes it is difficult to make a definitive diagnosis. As invasive methods (bronchoscopy, bronchoalveolar lavage, biopsy) are mostly contraindicated in these patients with severe neutropenia and thrombocytopenia, imaging techniques are especially important. It is a great challenge to differentiate infectious and noninfectious processes. CT and HRCT play an essential role in differential diagnosis. An early and accurate diagnosis is sometimes the only chance for survival.]

[Increasing importance of invasive fungal diseases]

PRINZ Gyula, SINKÓ János

[INTRODUCTION - Invasive mycoses are life-threatening fungal infections affecting patients with severe underlying conditions or impaired immune system. According to epidemiological studies, the incidence of invasive mycosis is increasing in several patient groups. CASE REPORT - In patients who require ICU care, the majority of invasive mycoses are caused by Candida species. A shift has been observed within the spectrum of pathogenic species. In patients undergoing chemotherapy for acute leukemia and in recipients of allogenic stem cell transplantation, however, an increased morbidity and mortality of invasive aspergillosis have been observed. The authors discuss current issues regarding the diagnosis and treatment of invasive fungal diseases on the basis of case reports. CONCLUSION - Invasive mycoses are lifethreatening infections affecting patients with severe underlying conditions. While the opportunities of state-of-the-art medicine are expanding, the incidence and significance of these infections increases. If detected and treated in time with appropriate antifungal agents, these infections can be efficiently treated.]
