Active clinical trials for "Pneumonia"

The purpose of the study is to assess whether lung ultrasound is able to detect lung injury after lung resection surgery.

This is a non-randomized single arm clinical study to observe the effect of Yinhu Qingwen Granule in the relief of fever and improvement of related-symptoms of patients with viral pneumonia.

This study will examine the effectiveness of a new laboratory method for detecting pneumocystis organisms in a salt-water (saline) oral wash. Pneumocystis infection in people with weakened immunity especially patients with HIV infection or cancer, organ transplant recipients and people receiving immune suppressing therapy can cause life-threatening pneumonia. Currently, pneumocystis infection is diagnosed by sputum analysis or bronchoalveolar lavage. For the sputum analysis, patients are induced to produce a sputum sample (liquid discharge from the lung) using a saline mist; however, many hospitals lack the expertise to perform this procedure. The second method, bronchoalveolar lavage, involves inserting a flexible tube into the lung and injecting saline to produce a specimen for diagnosis. This method, however, is time-consuming and can be uncomfortable. New techniques may allow the use of an oral wash to diagnose pneumocystis, even though an oral sample contains far fewer organisms than are obtained with the current methods. This study will examine whether new techniques, such as nucleic acid amplification, may enable a simple oral wash to be used effectively for diagnosis of pneumocystis infection. Patients 3 years of age and older with weakened immunity who have acute pneumonia may be eligible for this study. In addition, people at increased risk of infection with pneumocystis, including health care professionals, family members of patients, and other patients in health care facilities, may participate. Participants will have a medical history and review of medical records to determine their health status and determine if they have had recent respiratory problems or documented PCP. They will then provide an oral wash sample. For this procedure, subjects first rinse their mouth well. Then, they vigorously swish 50 milliliters of saline for 5 to 10 seconds and immediately repeat the procedure to provide two specimens. Washes may be requested daily, weekly, monthly, or for a period of time to be specified. Participants will also have two tubes of blood drawn (total of 20 milliliters, or 4 teaspoons) to test for evidence of pneumocystis. Although no other tests are required for this protocol, participants may be asked to provide optional add'l samples, as follows: If a sputum or bronchoalveolar lavage sample is required in the course of the patient s clinical mgmt, enough material will be obtained, if possible, for research purposes as well as what is needed for routine care. An induced sputum sample may be requested just for this protocol. For this procedure, a mask with a saline mist is placed over the face, inducing a cough that, it is hoped, will produce sputum from the lungs.

The purpose of this study is to investigate inherited genetic factors that play a role in the development of familial pulmonary fibrosis and to identify a group of genes that predispose individuals to develop pulmonary fibrosis. Finding the genes that cause pulmonary fibrosis is the first step at developing better methods for early diagnosis and improved treatment for pulmonary fibrosis. The overall hypothesis is that inherited genetic factors predispose individuals to develop pulmonary fibrosis.

This is an observational study in 750 individuals aged 14 years or older, diagnosed with Community Acquired Pneumonia (CAP) who meet all eligibility criteria in Coccidioides endemic regions. This study is designed to provide data on the prevalence of primary pulmonary coccidioidomycosis among persons presenting with CAP in endemic regions. Among individuals diagnosed with primary pulmonary coccidioidomycosis, we aim to describe the clinical course, predictors of the clinical course and compare the response to prescribed antifungal therapy versus no antifungal therapy. The hypothesis for patients with primary pulmonary coccidioidomycosis is that early treatment with antifungal therapy is effective in reducing the frequency, severity and associated adverse outcomes of infection with recently acquired coccidioidomycosis pneumonia. The study will be divided into Step 1 and Step 2. Step 1 will identify which subjects have primary pulmonary coccidioidomycosis based on the case definition for the protocol and Step 2 will follow subjects who meet the case definition and will observe their clinical management and clinical outcomes. Subjects will enroll in Step 1 within 28 days of symptom onset. In Step 1, blood work for serologic determination of Coccidioides infection will be drawn at the time of enrollment (Day 1), and again 21 days later if a positive result is not reported at Day 1. Subjects with a diagnosis of primary pulmonary coccidioidomycosis confirmed by positive serologic testing during Step 1 will enter Step 2 within 21 days of a positive test result; subjects with a negative serology at Day 1 and Day 22 will not be followed further. Subjects referred to the study after a diagnosis of primary pulmonary coccidioidomycosis confirmed by positive serologic testing will also be allowed to enter Step 2 directly within 21 days of a positive test result and within 7 weeks of symptom onset, as long as they meet study enrollment criteria. The primary objective is to assess the prevalence of primary pulmonary coccidioidomycosis (PPC) in subjects with community acquired pneumonia (CAP) in coccidioidomycosis endemic areas.

This nasopharyngeal (NP) carriage surveillance study was requested by the European Agency for the Evaluation of Medicinal Products as a post-licensing commitment to determine whether the use of the pneumococcal conjugate vaccines (PCVs) including 7 then 13 valents (introduced in 2001 and 2010, respectively) caused a shift in the distribution of Streptococcus pneumoniae serotypes in children with acute otitis media and modified the resistance of this bacterial species to antibiotics.

Novel coronavirus pneumonia (NCP) and acute respiratory distress syndrome (ARDS) are both associated with the prevailing upper respiratory tract infections caused by the RNA-containing SARS-CoV2 virus of the genius Betacoronavirus of the Coronaviridae family. As both the viral infiltration and infection progress, the host immune system response can be one of a rapidly developing fatal cytokine storm. In the ARDS or NCP ensuing progression, the patient often succumbs to the effects of the hyper pro-inflammatory response, hence contributing to the associated increased mortality as a result of the cytokine storm and associated pathogenesis.

This study looks at the side effects of chemotherapy and radiation (chemoradiation) followed by immunotherapy in patients with non-small cell lung cancer, with a particular focus on lung inflammation (pneumonitis). By collecting blood, stool and saliva samples, and data from lung function tests, researchers may be able to create a database of information about treatment and side effects in patients with non-small cell lung cancer who are receiving chemoradiation followed by immunotherapy. The information gained from this study may also help researchers find signs of problems with lung function earlier rather than later, since lung function is checked more often than routine care. This may improve how quickly these issues can be treated, and future patients may benefit from what is learned.

Establishment of a study network and patient cohort for pediatric CAP

Thoracic imaging, either with chest X-ray (CXR) or computed tomography (CT), is an essential part of the diagnosis of coronavirus disease-19 (COVID-19) in patients admitted to hospital with fever or respiratory symptoms. Inspite of the results of PCR tests are the gold standard, the sensitivity of CT for diagnosing COVID-19 is 97%. The specific epidemic contingency makes CT an accurate tool to stratify patients based on imaging patterns, predicting poor outcomes and the need for ventilation. Lung ultrasound (LUS) is widely used in emergency departments because it is broadly available, low-cost, and has a high accuracy for diagnosing pulmonary diseases. Despite the diagnostic power of LUS and its influence on decision-making and therapeutic management, there are still significant barriers to the widespread use of this tool. The advantages of LUS are more obvious in older patients with multimorbidity and restricted mobility, for whom high-quality CXR and CT scans are difficult to obtain. In the hands of experienced clinicians, LUS diagnostic accuracy for bacterial pneumonia is similar to chest CT. However, a correlation between LUS and CT findings in patient urgently hospitalized for severe COVID-19 pneumonia remains to be determined. COVID-19 leads to an aggressive inflammatory response that is actually the reaction of the immune system. Some patients exhibit pneumonia in both lungs, multi-organ failure, and even death. Individuals who have severe health conditions, like cancer, cardiovascular diseases, diabetes, and pulmonary diseases, are at higher risk of COVID-19 infection. Also, this dysregulated immune response resulting in excessive production of inflammatory cytokines and chemokines (as IL-1ra, IL-6, IP-10, G-CSF, MCP-1, MIP-1α and TNF) causes the development of cytokine release syndrome (CRS) which is considered as pathologic underpinning for disease progression and lead to severe collateral tissue damage. IL-6 may serve as a predictive biomarker for disease severity as its elevated levels were reported in several studies of COVID-19 infection. Also IL-6 levels were correlated with mortality in COVID-19 patients. IL-6 blockade is a promising strategy for COVID-induced CRS. In particular, clinical epidemiological studies are needed to determine if IL-6 and/or other inflammatory cytokine levels predict subsequent development and persistence of long COVID 19 viral pneumonia.
