Active clinical trials for "Pneumonia"

Pneumonia is one of the top causes of death in children aged below 5. More than 10% of children with severe pneumonia die. We are not sure that the currently recommended antibiotics used in children with pneumonia are the most effective. No studies have been carried out to find out whether children with pneumonia should be given intravenous (IV) fluids or nasogastric (NG) feeds. The SEARCH trial aims to find out which antibiotics and modes of feeding are the most effective in treating children with severe pneumonia and therefore helping reduce mortality.

Pneumonia is a major infectious cause of death worldwide and imposes a considerable burden on healthcare resources. Sphingosine-1-phosphate (S1P) is a bioactive sphingolipid and involved in many physiological processes including immune responses and endothelial barrier integrity. In term of endothelial barrier integrity, S1P plays a crucial role in protecting lungs from pulmonary leak and lung injury. Because of the involvement in lung injury, S1P could be the potential biomarker of pneumonia. Recently, our pilot study suggested that patients with CAP have significantly higher plasma S1P levels than healthy individuals. Interestingly, our observational study also showed significantly elevated S1P level in the patients who were treated with methylprednisolone during the hospitalization. Based on the above evidence, we hypothesize that S1P plays an important role in the pathobiology of pneumonia. Moreover, S1P is not only a useful biomarker for diagnosis of CAP, but also can be an indicator for using corticosteroids adjuvant therapy.

This is a phase 1, open-label, non-comparative, multicenter clinical study to evaluate the safety, tolerability, and pharmacokinetics of ceftolozane/tazobactam (MK-7625A) in pediatric participants with nosocomial pneumonia (NP).

The primary objectives of this study are to assess the safety, tolerability, and pharmacokinetics (PK) of cefiderocol after single-dose administration in hospitalized pediatric participants 3 months to < 12 years of age with suspected or confirmed aerobic Gram-negative bacterial infections and after multiple-dose administration in hospitalized pediatric participants 3 months to < 18 years of age with suspected or confirmed complicated urinary tract infection (cUTI), hospital-acquired bacterial pneumonia (HABP), or ventilator-associated bacterial pneumonia (VABP).

Since december 2019, acute respiratory disease due to 2019 novel coronavirus (2019-nCoV) emerged in Wuhan city and rapidly spread throughout China. There is no confirmed antivirus therapy for 2019-nCoV infection. Natural killer (NK) cells are innate lymphocytes that may serve as useful effectors against danger infection. The purpose of this clinical investigation is to evaluate the safety and efficiency of NK Cells in combination with standard therapy for pneumonia patients infected with 2019-nCoV.

A randomized, double-blind, single-center and controlled study comparing the efficacy and safety of intravenous administration of tranexamic acid to reduce blood loss in simultaneous bilateral total knee arthroplasty.

This trial will evaluate whether empirical treatment against cytomegalovirus and tuberculosis improves survival of HIV-infected infants with severe pneumonia.

Severe Community-acquired pneumonia (SCAP) is a leading global infectious cause of intensive care unit (ICU) admission (approximately 20%-30%), and the primary reason of mortality and morbidity in immunocompromised patients. There is a global increase of patients with distinct immunocompromised conditions due to the advance of cancer treatment, increasing biologics, and immunosuppressants for autoimmune diseases and growing organ transplant recipients, and it has been estimated that patients with immunocompromised conditions account for approximately 35% of all intensive care unit (ICU) admissions. Immunocompromised patients with SCAP have more factors to complicate with sepsis, respiratory failure, acute respiratory distress syndrome, and the mortality rate can be up to 50%. With the aim to apply early accurate antimicrobial therapy to improve clinical prognosis of SCAP patients with immunocompromised conditions, timely identification of pathogen is particularly important. Conventional microbiological diagnostic methods such as standard microbiologic cultures, microscopy, polymerase chain reaction (PCR), respiratory virus multiplex PCR, as well as pathogen-specific antigens and antibody assays, are currently commonly used to detect pathogens, although they have various limitations. However, conventional antimicrobial therapy depends on the results of conventional diagnostic methods, which may delay timely accurate antimicrobial therapy at the initial stage, and the mortality of immunocompromised patients with SCAP may be increased. Metagenomic next-generation sequencing (mNGS), which can determine pathogens more quickly (usually within 24h) and accurately comparing with conventional diagnostic methods by analyzing cell-free nucleic acid fragments of pathogens using appropriate lower respiratory tract (LRT) specimen, is increasingly used in severe respiratory infectious disease, especially among immunocompromised patients. This study aims to determine whether mNGS (using LRT specimen) guided antimicrobial treatment improves clinical prognosis of SCAP patients with immunocompromised conditions when compared with conventional antimicrobial treatment.

The goal of this randomized, controlled, open-labeled interventional clinical trial is to test the efficacy and safety of umbilical cord mesenchymal stem cells (UC-MSCs) in the treatment of severe and critical COVID-19 patients. The main questions it aims to answer are: 1. The efficacy of UC-MSCs in the treatment of severe and critical COVID-19 patients. 2. The safety of UC-MSCs in the treatment of severe and critical COVID-19 patients. 3. The potential immune mechanisms of UC-MSCs in the treatment of severe and critical COVID-19 patients. Participants will receive standard therapy, Paxlovid treatment or the UC-MSCs treatment. For the standard treatment, it will be conducted according the 9th edition of Chinese guidelines for COVID-19 infection. For UC-MSCs treatment, participants will be given UC-MSCs instillation at the first and fourth day after assignment. Blood examples will be taken at indicated time for arterial blood gas analysis and other tests. And participants should also objectively report their symptoms change and other information related to the treatment as listed the research protocol.

The goal of this randomized, controlled, open-labeled interventional clinical trial is to test the efficacy and safety of umbilical cord mesenchymal stem cells (UC- MSCs) in the treatment of severe and critical COVID-19 patients with refractory hypoxia even after sufficient standard treatment according to the tenth edition of Chinese guidelines for COVID-19 infection. The main questions it aims to answer are: 1. The efficacy of UC-MSCs in the treatment of severe and critical COVID-19 patients with refractory hypoxia. 2. The safety of UC-MSCs in the treatment of severe and critical COVID-19 patients. 3. The potential immune mechanisms of UC- MSCs in the treatment of severe and critical COVID-19 patients. Participants will receive standard therapy, or the UC-MSCs treatment. For the standard treatment, it will be conducted according the 10th edition of Chinese guidelines for severe or critical COVID-19 infection.
