Filter by:Background: - The immune system is made up of special cells, tissues, and organs that fight infections. Problems with this system may lead to frequent, severe, or unusual fungal infections. These infections are often difficult to treat. Researchers want to collect blood and tissue samples from people who have unusual, persistent or severe fungal infections or immune problems that increase the risk of these infections. Objectives: - To collect medical information and samples for a long-term study of people with immune system problems that lead to fungal infections. Eligibility: - People with a history of fungal infections caused by immune system problems. - Parents, children, and siblings of this group. - Healthy volunteers not related to the first two groups. Design: - This long-term study may last for up to 10 years. Those in the study may need to provide new information about every 6 months. The procedures for each person may vary with the particular diagnosis and the extent of fungal infection. Healthy volunteers may have only one or two visits. - At the first visit, those in the study will have a full medical history and physical exam. They will also provide blood. - Research procedures may include the following: - Saliva, urine or stool testing - Mouthwash collection for DNA testing - Collection of cheek cells, nail clippings, or vaginal fluid - Tests of leftover tissue or body fluid from previous medical procedures - Skin or oral mucous membrane biopsy - Collection of white blood cells - Followup visits will involve a physical exam and updated medical history. Blood, saliva, urine, or nail clipping samples may be taken for ongoing studies. Any additional tests or exams required by the study doctors may also be done. - Participants may withdraw from the study pool at any time.
In this study we will measure the concentration of the drug called voriconazole which is used to fight infections caused by fungus in children who usually are cancer patients and have their immune system down. Since we know the dose in adults, and we think we know the matching doses in the young patients ages 2 to less than 15 years old, we will compare the amount of drug that goes into the system with what we know works in adults. We give the drug by a needle directly into the blood, then few days later we stop that and give the drug by mouth. Meanwhile, we draw a little bit of blood at certain times to measure the drug in it.
The purpose of this study is to evaluate the efficacy and safety of itraconazole monotherapy in patients with ABPA.
SEIFEM 2010 study is a prospective, multicenter registry designed to identify and analyze risk factors for developing an invasive fungal infection in patients with newly diagnosed Acute Myeloid Leukemia, with particular interest on pre-hospital risk factors (i.e. those related to normal activities of daily life, such as occupation, location and type of residence, consume of tobacco, alcohol and others).
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.
The purpose of this study is to determine whether there itraconazole is effective in the treatment of chronic cavitary pulmonary aspergillosis
The purpose of this study is to evaluate the diagnostic potential of biomarkers for invasive pulmonary aspergillosis in exhaled breath condensate.
The purpose of this study is to see if giving people with CF and ABPA enough vitamin D to make their blood levels of the vitamin higher, will reduce the allergic response in their body and make the symptoms caused by ABPA better.
The purpose of this study is to evaluate the therapeutic effectiveness of combination antifungal therapy (CAT) of voriconazole plus micafungin versus voriconazole plus placebo equivalent as primary therapy for invasive aspergillosis (IA) in patients with hematological cancer.
This study aims to compare the safety, tolerability, and efficacy of voriconazole and anidulafungin in combination versus voriconazole alone in pediatric subjects aged 2 to 17 years with invasive aspergillosis.
