Active clinical trials for "Aspergillosis"

Corticosteroids exposure is a common risk factor for invasive fungal infections. Systemic corticosteroid therapy treats several medical conditions, including rejection in solid organ transplant recipients, malignancy, and autoimmune or inflammatory diseases. Corticosteroid exposure is a well-known risk factor for developing PJP. Still, it remains unclear how prior corticosteroid exposure influences the presentation, severity, and mortality of opportunistic fungal infections. The investigators aim to prospectively characterize the corticosteroid use as a dose response to inform risk of invasive fungal infections.

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.

This study will establish a non-invasive diagnostic approach and evaluate clinical outcomes for children at high-risk for pulmonary invasive fungal infection (PIFI).

To assessed the current situation and outcome of critically ill patients with invasive aspergillus infection.

The purpose of this study is to identify the number of individuals with severe CoVID who require ventilator support and who develop serious fungal infections. The study is an observational study, meaning that we are not providing any intervention that does not involve usual standard of care. Our chief goal is to find evidence of fungal infection by using traditional, approved methods of diagnosis, but by applying these methods in the same way and frequency among all study participants. We will be looking especially for evidence of a fungal infection known as Aspergillus, which can causes a serious lung infection called invasive aspergillosis (IA).

This trial is aimed to study the immunological and pathological characteristics of influenza versus non-influenza severe community-acquired pneumonia patients in ICU.

A prospective multi-center observational study to assess the incidence of influenza-associated pulmonary aspergillosis (IAPA) in ICU patients and to identify host- and pathogen related risk factors for IAPA in EORTC negative ICU patients with severe influenza.

The purpose of the trial is to evaluate the safety and efficacy of a new antifungal with a novel mechanism of action in immunocompromised adults with invasive aspergillosis.

This study tests the effects of an experimental drug PC945 in people with cystic fibrosis whose lungs are infected by the fungus Aspergillus fumigatus. PC945 may be useful in treating patients infected with Aspergillus fumigatus as, unlike the usual treatments, it is inhaled into the lung and has been designed to stay there and treat the infection. Participants will continue to be treated with their usual cystic fibrosis treatment and will also receive PC945. The amount of fungus in the patients' phlegm will be measured over the course of the study. The study will take place at multiple sites in UK and will include approximately 18 participants. The maximum study duration will be about 16 weeks.

The purpose of this study is to evaluate the safety and effectiveness of micafungin in combination with AmBisome as first-line therapy in the treatment of invasive aspergillosis.
