Active clinical trials for "Pneumonia"

This study will evaluate how heartburn may lead to different types of inflammation in one's airways. Additionally, the study will determine whether aggressive treatment of heartburn results in improvement in both symptoms of heartburn and asthma but also in documented improvement in airway inflammation as determined by biopsy. The results of this study will be important in directing future research into the relationship between heartburn and asthma and may provide a clue whether certain subtypes of asthma may be caused primarily by gastroesophageal reflux (GER).

Respiratory failure in term newborns is associated with increased rates of death and long-term neurodevelopmental problems. This large international multicenter trial randomized newborns who had failed to respond to intensive care, including high levels of ventilator support, to receive either inhaled nitric oxide (iNO) or 100 percent oxygen to test whether iNO would decrease their risk of dying or requiring temporary lung bypass. Infants were followed during their initial hospitalization; their outcome was assessed at 18 to 24 mos of age.

The purpose of this study is to analyze in depth the relationship of myeloid cell subpopulations during infection by Severe acute respiratory syndrome coronavirus 2 (SARS-Cov2), the virus mediating Covid-19. Myeloid cells include neutrophils, monocytes and dendritic cells, each divided into subpopulations with different functions in immune defense and immune pathologies. The study is based on the following hypotheses: Infection and the interferon response to infection may induce hyperactive or immunosuppressive differentiation of myeloid cells, that may be treated by specific inhibitors. Some myeloid cell subpopulations currently identified in our laboratories might be markers for Covid-19 prognosis. Alternative receptors may be present on myeloid cells, inducing the cytokine storm, a target for therapy. The expression of Interferon (IFN) receptor and IFN responding genes on myeloid cells and on respiratory epithelial cells may correlate with prognosis and indicate potential treatment targets. Interferon responses are known to be skewed during Covid-19, but some IFN subtype polymorphisms may correlate with prognosis and these subtypes migt be supplemented or inhibited for therapy.

Exposure to molds in dwellings is a public health problem. Diagnosis of hypersensitivity pneumonitis due to mold exposure at home (domestic HP) are increasing. To perform the serodiagnosis of domestic HP a cohort constitued of proven cases and exposed healthy controls are needed. The HOME HP study aimed at obtaining a cohort of proven cases and exposed controls in order to be able to improve the serodiagnosis of domestic HP.

Assessment of cardiovascular disorders using echocardiography and arterial stiffness; comparative noninvasive assessment of volatile organic compound (eVOC) exhale breath patterns in patients with different chronic respiratory diseases with age and gender-matched healthy adults in order to identify a disease-specific exhaled eVOCs profiles and markers of respiratory and cardiovascular disorders.

The goal of this individual patient data meta-analysis is to estimate the attributed and the associated health burden related to bloodstream infections, pneumonia, skin and soft tissue infections, surgical site infections and urinary tract infections, caused by target drug-resistant pathogens, in high income countries. The main question[s] it aims to answer are: Are common infections caused by drug-resistant pathogens associated with an increased health burden, when compared with individuals with the same infection caused by a susceptible strain (attributed burden)? Are common infections caused by drug-resistant pathogens associated with an increase health burden, when compared with individuals without the infection under study (associated burden)?

The primary purpose of the study is to determine the degree of penetration of cefiderocol into infected lung tissue in hospitalized adults with bacterial pneumonia who are being mechanically ventilated.

This study compares three different therapies for treatment of refractory Pneumocystis carinii pneumonia (PCP) in patients with AIDS. "Refractory" means that the patient has failed to respond to at least 4 days of treatment with either of two standard therapies: (1) sulfamethoxazole/trimethoprim (SMX/TMP) or (2) pentamidine (PEN). This study compares therapy with trimetrexate (TMTX) and leucovorin (LCV) to standard therapy and standard therapy plus high-dose steroids (methylprednisolone). The purpose is to find better and safer forms of treatment for PCP in AIDS patients. There is at present no scientific information about the best treatment for an AIDS patient with PCP who is not improving while receiving the standard therapies (SMX/TMP or PEN). New drug treatments are available, including steroid therapy and TMTX, but there is no information proving that these new treatments work better than the standard therapies.

Open label two arms, non randomized Convalescent Plasma treatment to severe and critical pneumonia COVID-19 hospitlaized patients compared to a historical cohort with matched controls.

This is a randomized-controlled prospective study to be conducted at Danbury Hospital and Norwalk Hospital to evaluate oscillatory positive expiratory pressure (OPEP) devices for "airway clearance" (helping to clear out phlegm or mucous from your lungs and bronchial tubes) in the treatment of patients admitted to the hospital with pneumonia. Approximately 200 subjects are expected to participate in this study.
