Active clinical trials for "Pulmonary Aspergillosis"

Voriconazole Inhalation Powder is available on an expanded access basis to patients with pulmonary aspergillosis for up to 12 weeks. Duration of treatment may be extended on a case-by-case basis depending on drug availability and after discussion with the Sponsor.

This is a multicenter study with the aim to determine the prevalence of influenza-related invasive pulmonary aspergillosis in Swedish intensive care units and to assess the clinical impact of and risk factors for influenza-related invasive pulmonary aspergillosis

A spirometry study is performed in a patient diagnosed with allergic bronchopulmonary aspergillosis. An initial measurement is carried out and the patient is then put on a four-week physiotherapy treatment plan. Four spirometry measurements were taken to assess different variables and an improvement in all the spirometry values was established.

Invasive pulmonary aspergillosis (IPA) is an opportunistic infection that primarily affects recipients of solid organ transplants (SOTs) and patients with chemotherapy- induced neutropenia.Although both of these populations are at high risk for IPA, they differ with regards to the specific defects in host defense mechanisms that increase their risk for IPA. Chemotherapy- induced neutropenia is the principal defect affecting patients with hematologic malignancies, whereas transplant recipients tend to have dysfunctional T cells and phagocytes, as a result of immunosuppressive drug therapy. Thus, the patterns of IPA-related infection and inflammation may differ according to the type of underlying immune defect. Although the clinical and radiological features of IPA in patients with neutropenia have been extensively studied, little is known about the characteristics of IPA in SOT recipients. The investigators therefore compared the IPA- related clinical and radiological findings in SOT recipients with those of neutropenic patients.

The purpose of this study is to evaluate the diagnostic potential of biomarkers for invasive pulmonary aspergillosis in exhaled breath condensate.

This study aims to assess the value of TARC in diagnosis of allergic Bronchopulmonary Aspergillosis.

Aspergillus-specific IgG assays for the diagnosis of chronic pulmonary aspergillosis (CPA)

To investigate the relationship between cytochrome P450 (CYP) 2C19 genetic polymorphism and the steady-state blood concentration of voriconazole in Chinese patients with invasive pulmonary aspergillosis (IPA), and to assess the effects of voriconazole trough concentration on the prognosis of IPA patients.

The main aim of this study is to determine whether the levels of different inflammatory cytokines in the serum and BALF (bronchoalveolar lavage fluid) are relative to the severity and exacerbations of ABPA (allergic bronchopulmonary aspergillosis).

Invasive aspergillosis is a serious and often fatal infection in patients who are neutropenic or have undergone solid organ or stem cell transplantation. However, early diagnosis of invasive aspergillosis is a challenge. Reiss and Lehmann first described the value of serum Galactomanna (GM) for diagnosis of invasive pulmonary aspergillosis in 1979. The availability of the Platelia Aspergillus, a sandwich ELISA that has been approved by FDA in 2003 for managing patients at risk of invasive aspergillosis because of the early detection of the GM antigen. In several studies so far the specificity of the serum galactomannan assay was greater than 85%; however, variable sensitivity from 29~100% was noted over years. In addition, low values and false-negative results are seen more often in nonneutropenic and solid organ transplantation patients as opposed to severely granulocytopenic patients .There are several factors that might explain the reported difference in the performance of antigen detection, including the biological factors and epidemiological factors. In recent years, specimens of other body fluids are increasingly used for detection of Aspergillus galactomannan antigen, including urine, bronchoalveolar lavage(BAL) fluid, cerebrospinal fluid and even the tissue specimen. However, the sensitivity and specificity of the GM detection in various specimens still have considerably variation. Ultrasound-guided transthoracic aspirate is a safe and useful method for collecting specimens for accurate bacteriologic diagnosis of lung abscess and obstructive pneumonitis10. We also reported a study of diagnosis of pulmonary Cryptococosis by ultrasound guided percutaneous aspiration. We plan to perform a prospective single-center study to investigate the role of GM in the target organ (lung tissue/fluid) by using ultrasound-guided fine needle aspirate for early diagnosis invasive aspergillosis compared with the serum galactomannan.
