Active clinical trials for "Pneumonia"

To assess the clinical efficacy of ANG-3777 relative to the standard of care in reducing the severity and progression of pulmonary and renal dysfunction and mortality in adult patients hospitalized with COVID-19 pneumonia

Inflammatory diseases favour the onset of venous thromboembolic events in hospitalized patients. Thromboprophylaxis with a fixed dose of heparin/low molecular weight heparin (LMWH) is recommended if concomitant inflammatory disease. In severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) pneumonia an inflammation-dependent thrombotic process occurs and platelet activation may promote thrombosis and amplify inflammation, as indicated by previous experimental evidence, and the similarities with atherothrombosis and thrombotic microangiopathies. Antiplatelet agents represent the cornerstone in the prevention and treatment of atherosclerotic arterial thromboembolism, with limited efficacy in the context of venous thromboembolism. The use of acetylsalicylic acid may improve inflammation and respiratory function in humans as indicated by the results of observational studies. There are no validated protocols for thrombosis prevention in Covid-19. There is scientific rationale to consider acetylsalicylic acid for the prevention of thrombosis in the pulmonary circulation and attenuation of inflammation. This is supported by numerous demonstrations of the anti-inflammatory activity of antiplatelet agents and the evidence of improvement in respiratory function both in human and experimental pathology. The hypothesis underlying the present study project is that in Covid-19 platelet activation occurs through an inflammation-dependent mechanism and that early antithrombotic prophylaxis in non-critical patients could reduce the incidence of pulmonary thrombosis and respiratory and multi-organ failure improving clinical outcome in patients with SARS-CoV2 pneumonia. The prevention of thrombogenic platelet activity with acetylsalicylic acid could be superior to fixed dose enoxaparin alone. The proposed treatment is feasible in all coronavirus disease 2019 (COVID-19) patients, regardless of the treatment regimen (antivirals, anti-inflammatory drugs), except for specific contraindications. To this aim, the investigators a randomised, placebo-controlled, double blind, parallel arms study to investigate the potential protection of acetylsalicylic acid towards the progression of lung failure in patients admitted to a medical ward for SARS-CoV-2 pneumonia. A 15-day treatment period is considered. Primary endpoint is the occurrence of one of the following events: admission to an intensive care unit, requirement of mechanical ventilation, PaO2/FiO2 less than 150 mm Hg.

The trial aims to assess the impact of cheap, licenced and widely available investigational products on the natural history of SARS-CoV-2 infection in 2 groups of patients - those with mild or moderate pneumonia (Cohort 1) and those with severe pneumonia (Cohort 2), through randomisation to non-identical placebo or intervention arm.

The investigator's goal in this study is to determine the clinical efficacy and safety of continuous infusion in comparison with standard intermittent infusion.

The mortality of pneumonia with extensively drug resistant Acinetobacter baumannii (XDRAB) is still high, even if these patients received certain strong anti-infection treatment such us the combination of cefoperazone-sulbactam (C/S) and minocycline. Health airway lining fluid is mildly alkaline but airway acidification usually appears for the infection of XDRAB. The hypothesis is offered that the biologic activity of XDRAB might be inhibited if the circumstance including pH is changed. In the vitro study we observed that the inhibit effect of antibiotics on XDRAB growth was improved significantly by alkaline solution within the scope of physiology. So the aim of this clinical study is to explore the effects of nebulization of alkaline Solution on C/S plus minocycline on the pneumonia with XDRAB.

To investigate the non inferiority of a short lasting antibiotic treatment (3 days) when compared to a long lasting antibiotic treatment (8 days), at Day 15 after the beginning of treatment in terms of clinical efficacy, in adults admitted to emergency services for a non severe Community Acquired Pneumonia (PAC), who responded well to 3 days of beta-lactamin treatment (3GC or A/AC).

Pulmonary inflammation is an independent risk factor for disease progression in cystic fibrosis patients (CF). Yet, no effective treatment is known to reduce this detrimental inflammation. Dysbiosis of the gut microbiota has been linked to inflammation in several inflammatory diseases. As children with CF have different faecal microbiota from their healthy siblings, modulating gut microbiota by lactobacillus rhamnosus diet supplementation might be a strategy to target the inflammatory state in CF. Study subjects (CF or healthy control) will receive either placebo or lactobacillus rhamnosus once daily as dietary supplementation for 12 weeks. After a one-week washout phase, they will be switched for another 12 weeks to the other trial arm. Effect on in intestinal and pulmonary inflammation as well as clinical outcome will be studied.

Ventilator-associated pneumonia (VAP) is an important cause of morbidity and mortality in ventilated critically ill patients specially in intensive care unit (ICU). It is associated with an increased duration of mechanical ventilation, high death rates and increased healthcare costs in the development country. Although VAP is preventable and many practices have been demonstrated to reduce the incidence of this disease, the morbidity is still so high. VAP is hard to cure and the mortality is about to 40% which was reported in China in 2004. If the bacteria of multidrug-resistance(MDR) is isolated, the mortality can increase to 70%. So much more methods should be needed in treating VAP in addition to using antibiotics. Ulinastatin is a serine protease inhibitor with a molecular weight of 67,000 found in healthy human urine. It is used worldwide for patients with inflammatory disorders, including disseminated intravascular coagulation(DIC),shock, and pancreatitis . Furthermore, ulinastatin administration can help reduce sepsis, prevent multiple organ dysfunction, and modulate immune functions. Actually, three studies have showed that ulinastatin treatment is associated with reduced the levels of inflammatory factors in blood serum in patients with acute respiratory distress syndrome(ARDS).Though analyses of serum inflammatory factors such as tumor necrosis factor (TNF)-α and interleukin (IL)-6 have been used to determine the degree of systemic inflammation under various clinical conditions, they can not reflect the degrees of lung infection directly. Basing on the results of previous studies, meta analyses and system reviews, the investigators hypothesized that the anti-inflammatory function of ulinaststin may also decrease the levels of inflammatory factors in bronchoalveolar lavage(BAL) fluid in Patients with VAP. In addition there is no prospective study to investigate the role of ulinastatin in BAL. The investigator hopes that this study can approve the relationship between ulinastatin and inflammatory factors in BAL. And it can improve the processes,outcomes and costs of critical care as well.

The objective is to assess the effect of simvastatin on immunology, inflammatory, and coagulation responses, and mortality in elderly with pneumonia based. The primary outcome is mortality event. The hypothesis of this study is that simvastatin therapy will reduce mortality in elderly with pneumonia.

Evaluation the efficacy and safety profile of trimethoprim/sulfamethoxazole as Pneumocystis carinii pneumonia (PCP) prophylaxis in Patients With Connective Tissue Diseases (CTD) treated with high-dose glucocorticoids and immunosuppressive agents. Open-labeled, randomized, prospective single-center clinical trial. Observation period of 12 weeks.
