Filter by:Background: An intact hypothalami-pituitary-adrenal (HPA) axis with an effective intracellular anti-inflammatory activity of glucocorticoids is indispensable for host survival during stress upon exposure to an infectious agent. Community-acquired pneumonia (CAP) is characterized by significant mortality and increased circulating inflammatory cytokines. Despite adequate antimicrobial therapy mortality rates for CAP have not changed over several decades. The use of corticosteroids in patients with CAP is inconclusive. Study aim: To compare a 7 days treatment with prednisone and placebo in patients with community-acquired pneumonia with respect to time to clinical stability. Study hypothesis: The investigators hypothesize that use of corticosteroids will lead to a 25% relative risk reduction for death and clinical instability. Study type: randomized double blind intervention study Patients: 800 patients with community-acquired pneumonia
This study is an observational surveillance study to identify adults 50 years and older who present to a study healthcare facility with signs and symptoms of Community-Acquired Pneumonia.
The purpose of this study is to assess the efficacy of glucocorticoids as an adjuvant therapy in patients with severe community-acquired pneumonia (CAP) (Fine V). The hypothesis of the study is that glucocorticoids can modulate the excessive inflammatory response in patients with severe CAP without any significant side effects, showing a benefit in the percentage of non-response to the empiric antimicrobial treatment.
The purpose of this study is to determine whether a monotherapy with a Beta-Lactam is not inferior to an association of a Beta-Lactam and a macrolide in treating adult patients with community-acquired pneumonia.
The purpose of this study is to compare the efficacy, safety and tolerance of 2 different dose levels of oral NXL103 with oral comparator in the treatment of community acquired pneumonia in adults
Key words : serum, pleural effusion, procalcitonin, pneumonia Pneumonia is the common cause of pleural effusion (ranged 2nd) and bacterial infection is the main etiology of pneumonia. Procalcitonin, the prohormone of calcitonin, is a 116 amino-acid protein produced by C-cell of the thyroid gland. During severe infection, procalcitonin is probably produced by extra-thyroid tissues and the concentration increased rapidly in bacterial infection but remains low in viral infections. However, the exact origin and pathophysiological role of procalcitonin during sepsis is not clear and it is not a marker of infection as such, since localized infections or infections with no systemic manifestation cause a little if any increase in procalcitonin levels. This study will focus on assessing the value of procalcitonin in pleural effusion for diagnosis, severity and prognosis among community-acquired pneumonia with pleural effusion, such as in serum. 100 patients with clinical pneumonia infection score over six points diagnosed of community-acquired pneumonia and proved to have pleural effusion by chest sonography on admission will be studied prospectively. Serum and effusion procalcitonin levels will be measured initially and 3 days later after medical therapy. Bacterial pneumonia will be identified if bacteria was cultured from any one of the three kinds of specimen, including blood, pleural effusion or bronchoalveolar lavage. Then we will divide one hundred of patients into bacterial or non-bacterial groups. Finally, we will analyze demographic and procalcitonin data of serum and pleural effusion between these two groups and compare the difference between the severe or mild and response or non-response bacterial community-acquired pneumonia statistically. The aim of the study will be to verify whether procalcitonin levels measured in the serum and pleural effusion could serve as a predictor for bacterial community-acquired pneumonia with pleural effusion and the different levels will also be indicative of severity and prognosis. We hope that the predictor from pleural effusion will be more sensitive or specific than that from serum and could be detectable in localized bacterial infection.
The purpose of this study is to determine if the use of antibiotic guidelines and thus antibiotics can be improved through a description of possible barriers leading to tailored interventions.
The aim of the study is to investigate the bacterial causes in community acquired pneumonia in adults admitted to hospital in two counties in Norway and to look at possible factors that makes the patients susceptible to pneumonia.
This study will test the safety and efficacy of TG-873870(Nemonoxacin) compared with Levofloxacin in adult patients with Community-Aquired Pneumonia(CAP)
The purpose of this study is to determine the safety and efficacy of ONO-5046Na in patients with acute respiratory failure associated with community-acquired pneumonia
