Active clinical trials for "Pneumonia"

The goal of this clinical trial is to determine the effect of a self-instructional module regarding ventilator-associated pneumonia care bundle prevention on internship students' knowledge and clinical performance in pediatric intensive care unit.The hypotheses of this study were as follows: Internship students who are taught by VAP care bundle prevention self-instructional module exhibit higher scores in knowledge test about VAP care bundle prevention than those who are not. Internship students who are taught by VAP care bundle prevention self-instructional module exhibit higher scores in performing the VAP care bundle prevention procedure than those who are not. Internship students who are taught by VAP care bundle prevention self-instructional module exhibit more positive feedback about it than those who are not.

The group aged 18-59 years old, the group ≥60 years old, and the group aged 2-17 years old were successively assigned to the group. Subjects in each age group were randomly vaccinated with 1 dose of experimental vaccine or control vaccine in a ratio of 1:1, with 48 people in each group receiving each dose. After the safety assessment was conducted on the 8th day after the first dose, the next age group could be enrolled only if the preliminary safety assessment results met the protocol requirements. When each age group is enrolled, laboratory index screening can be conducted 3 days in advance (the validity period of laboratory index detection results is 3 days). The progression of age groups is as follows: Group 18-59 years old (48 people: 1 dose) → Group ≥60 years old (48 people: 1 dose) → Group 2-17 years old (48 people: 1 dose) Safety observation: All subjects were observed on site for 30 minutes after vaccination, abnormal laboratory indicators (blood biochemistry, blood routine) of all subjects were observed on day 4 after vaccination, and adverse events of all subjects within 0-7 days were actively followed up by the researchers, and subjects were instructed to record the body temperature measured every day and adverse events (if they occurred) in the diary card. All subjects continued to observe adverse events within 8-28 days and made relevant records. All subjects were required to continue follow-up for SAE status up to 6 months after basic immunization. Immunogenicity observation: Blood samples were collected before and 28 days after vaccination, and serum antibodies were detected by ELISA.

Statins with their powerful anti-inflammatory, immunomodulatory, and antioxidant properties make them candidate members to be used in the management of sepsis and different types of infections including pneumonia. This study aims to determine whether adjunctive statin therapy decreased day- 28 mortality among ICU patients with ventilator-associated pneumonia (VAP) & number of ventilator-free days (after successful weaning) between day 1 and both day 28.

The purpose of this study is to conduct a randomized clinical trial to compare an antibiotic strategy based on a novel diagnostic test, polymerase chain reaction (PCR) to usual care, in critically ill adults with pneumonia suspected to be caused by methicillin resistant staphylococcus aureus (MRSA). The investigators hypothesize that when automated PCR is used to guide antibiotic therapy, antibiotic exposure will be reduced in critically ill subjects with pneumonia.

This study will investigate the safety and efficacy of the administration of inhaled GM-CSF to patients with respiratory virus-associated pneumonia.

The scientific community is in search for novel therapies that can help to face the ongoing epidemics of novel Coronavirus (COVID-19) originated in China in December 2019. At present, there are no proven interventions to prevent progression of the disease. Some preliminary data on SARS pneumonia suggest that inhaled Nitric Oxide (NO) could have beneficial effects on COVID-19 due to the genomic similarities between this two coronaviruses. In this study we will test whether inhaled NO therapy prevents progression in patients with mild to moderate COVID-19 disease.

This is a Phase 2, proof of concept, randomized, placebo-controlled, multicenter study to evaluate the ability of LB1148 to attenuate pulmonary dysfunction associated with COVID-19 pneumonia. The primary objective of this study is to determine if enteral administration of LB1148 will effect disease progression in hospitalized patients with moderate to severe COVID-19 via measurement of the proportion of subjects alive and free of respiratory failure at Day 28.

The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which originated in Wuhan, China, has become a major concern all over the world. Convalescent plasma or immunoglobulins have been used as a last resort to improve the survival rate of patients with SARS whose condition continued to deteriorate despite treatment with pulsed methylprednisolone. Moreover, several studies showed a shorter hospital stay and lower mortality in patients treated with convalescent plasma than those who were not treated with convalescent plasma. Evidence shows that convalescent plasma from patients who have recovered from viral infections can be used effectively as a treatment of patients with active disease. The use of solutions enriched of antiviral antibodies has several important advantages over the convalescent plasma including the high level of neutralizing antibodies supplied. Moreover, plasma-exchange is expensive and requires large volumes of substitution fluid With either albumin or fresh frozen plasma, increasing the risk of cardiovascular instability in the plasma donor and in the recipient, which can be detrimental in a critically ill patient with COVID 19 pneumonia. The use of plasma as a substitution fluid further increases treatment costs and is associated with risk of infections, allergic reactions and citrate-induced hypocalcemia. Albumin is better tolerated and less expensive, but exchanges using albumin solutions increase the risk of bleeding because of progressive coagulation factor depletion. The aforementioned limitations of plasma therapy can be in part overcome by using selective apheresis methods, such as double-filtration plasmapheresis (DFPP)3. During DFPP, plasma is separated from cellular components by a plasma filter, and is then allowed to pass through a fractionator filter. Depending on the membrane cut-off, the fractionator filter retains larger molecules and returns fluid along with smaller molecules to the circulation. Thus, the selection of a membrane with an appropriate sieving coefficient for IgG allows to efficiently clear autoantibodies in patients with antibody-mediated diseases (e.g., macroglobulinemia, myasthenia gravis and rheumatoid arthritis) with negligible fluid losses and limited removal of albumin and coagulation factors1. In patients with severe membranous nephropathy and high titer of autoreactive, nephritogenic antibodies against the podocyte-expressed M type phospholipase A2 receptor (PLA2R), DFPP accelerated anti PLA2R depletion4. Measurement of the antibody titer in treated patient and recovered fluid showed that antibody removal was extremely effective and that large part of antibodies was removed during the first DFPP procedure. This therapeutic regimen was safe and well tolerated and easy to apply4. In an ongoing pilot study we found that the same methodological approach can be used to remove circulating antibodies from patients who recovered from COVID 19 and to infuse these antibodies in patients with active viral infection. Treatment was well tolerated and preliminary findings are encouraging. Thus, in this novel pilot study we aim to explore whether the infusion of antibodies obtained with one single DFPP procedure from voluntary convalescent donors could offer an effective and safe therapeutic option for patients with earlier stages of coronavirus (COVID-19) pneumonia requiring oxygen supply without mechanical ventilation.

Chlorhexidine is a effective strategy in reducing ventilator associated pneumonia. However, it is unclear if prophylactic 0.12% chlorhexidine oral rinse can reduce the risk of non-ventilator hospital-acquired pneumonia among hospitalized patients.

The purpose of this study is to evaluate safety, tolerability, and pharmacodynamics of MK-5475 after administration of multiple doses to participants with COVID-19 pneumonia. The primary hypothesis is that MK-5475 when administered to participants with COVID-19 pneumonia and hypoxemia improves arterial oxygenation as measured by the ratio of blood oxygen saturation to fraction of inspired oxygen (SpO2/FiO2 ratio) compared to placebo.
