Community-Acquired Pneumonia (CAP)

Community-acquired pneumonia (CAP) refers to infectious parenchymal lung inflammation acquired outside hospital settings. In China, its incidence is 7.13 per 1000 person-years, with over 10 million new cases annually. Elderly CAP patients carry a higher mortality risk. The predominant pathogens of CAP in China are Mycoplasma pneumoniae and Streptococcus pneumoniae, followed by Haemophilus influenzae, Staphylococcus aureus and other pathogens. Commonly used antibacterial agents include macrolides, penicillins, cephalosporins, respiratory quinolones and tetracyclines. Nevertheless, drug resistance is prevalent nationwide. Specifically, the resistance rate of Mycoplasma pneumoniae to macrolides ranges from 54.9% to 71.7%, while that of Streptococcus pneumoniae reaches as high as 77.2% to 93.8%. Therefore, novel antibacterial agents covering common pathogens with low cross-resistance are urgently needed. Lefamulin is the first systemic pleuromutilin antibacterial agent for human use. It binds to the peptidyl transferase center of bacterial 50S ribosomal subunit via dual A/P sites to inhibit bacterial protein synthesis. It features low cross-resistance and low potential to induce drug resistance, and exerts broad-spectrum antibacterial activity against common typical and atypical pathogens (including multi-drug resistant strains) causing CAP. Multiple Phase III randomized controlled trials have verified that lefamulin achieves favorable early clinical response (ECR) and investigator-assessed clinical response (IACR) in CAP patients, providing solid evidence-based support for its clinical application. As a safer and more effective therapeutic option for CAP, lefamulin has been recommended by domestic and international clinical guidelines and expert consensus. This study aims to evaluate the safety and efficacy of lefamulin in real-world clinical treatment among Chinese patients with CAP.

This study aims to establish a standardized, synchronized data collection system for pediatric symptom questionnaires, cough sounds, and breath sounds, and to construct a multimodal database of pediatric respiratory diseases including both disease cases and healthy controls. Using the final research labels determined by clinicians' diagnoses, health status assessments, and research team review as the reference standard, this study will develop and validate a multimodal assisted diagnostic model for common pediatric respiratory diseases based on symptom questionnaires, cough sounds, and breath sounds. The study will primarily evaluate the diagnostic performance of the model in distinguishing healthy children from children with respiratory diseases, screening for asthma and asthma-related cough, and identifying pneumonia, tracheitis/bronchitis, upper airway-related diseases, and common causes of chronic cough. It will also assess the incremental value of cough sounds and breath sounds beyond symptom questionnaire information.

The goal of this clinical trial is to learn if icosapent ethyl (Vascepa) works to lessen the amount of inflammation in adults diagnosed with Community-Acquired Pneumonia (CAP). The main question it aims to answer is: What is the effect of taking Vascepa on inflammation in the arteries in patients with CAP? Researchers will compare the drug Vascepa to a placebo (a look-alike submstance that contains no drug) to see if Vascepa works to reduce inflammation in patients with CAP. Participants wil: * take Vacscepa or a placebo twice a day for 6 months * Visit the clinic 3 times (baseline, 30 days, and 6 months) for checkups and tests

The goal of this clinical trial is to learn if NRICM102 (a Traditional Chinese Medicine) works to treat community-acquired pneumonia (CAP) in adults when added to standard antibiotic therapy. It will also learn about the safety of NRICM102. The main questions it aims to answer are: 1. Does NRICM102 help participants reach clinical stability faster compared to placebo? 2. What medical problems do participants have when taking NRICM102? Researchers will compare NRICM102 to a placebo (a look-alike substance that contains no drug) to see if NRICM102 works as an add-on treatment for community-acquired pneumonia. Participants will: 1. Take NRICM102 or a placebo (2 sachets, 3 times daily) in addition to standard intravenous antibiotic treatment for 7 days 2. Be hospitalized and visited by the study team on Day 1, Day 4, and Day 8 for vital sign monitoring, symptom assessments, laboratory tests, and chest X-ray examinations 3. Be contacted by telephone on Day 30 to check if they were readmitted to the hospital after discharge

In North America, up to 5% of preschoolers develop community-acquired pneumonia (CAP) every year. Pneumonia is the second-leading reason for paediatric hospitalization in both Canada and the US; approximately 20% of children hospitalized with CAP may need intensive care, which can result in significant morbidity. Given this burden of disease, it is critical that CAP is managed appropriately. Specific therapy for CAP is dependent on microbiologic aetiology, as bacterial disease will improve with antibiotic treatment.

Aim: Demonstrate the equivalent efficacy and superior safety of Ceftriaxone 1 gram daily compared with Ceftriaxone 2 grams daily among hospitalized patients with community-acquired pneumonia who are not admitted to the intensive care unit.\<p\> Hypothesis: Among hospitalized patients outside of the intensive care unit with community-acquired pneumonia who are prescribed Ceftriaxone, a dosage of 1 gram daily will be associated with an equivalent rate of clinical cure and fewer adverse events than a dosage of 2 grams daily.

The goal of this cluster randomized controlled trial is to determine the optimal treatment for community aquired pneumonia (CAP). The study compares the effects and side effects of hydrocortisone and prednisolone in patients above 18 years old diagnosed with severe CAP. The main question is whether there is a difference in all cause mortality within thirty days. Participants will be randomized to receive treatment with either hydrocortisone or prednisolone.

This is a multicenter, randomized controlled trial designed to evaluate the impact of tNGS in patients with community-acquired pneumonia who experience initial treatment failure.

The goal of this clinical trial is to determine if a "watch and wait" antibiotic strategy, called Safety Net Antibiotic Prescribing (SNAP), can safely reduce unnecessary antibiotic use while ensuring that children diagnosed with community-acquired pneumonia get better from their illness. The main aims of this study are: * To compare the effectiveness of SNAP versus immediate antibiotic prescribing in children with mild community-acquired pneumonia (CAP) * To identify which patient groups benefit most from the SNAP strategy * To identify factors that shape implementation of each prescribing strategy. Researchers will compare the SNAP strategy (where parents or guardians are instructed to give antibiotics only if their child is not improving after 72 hours, or sooner if they are worsening) to the immediate antibiotic prescribing strategy (where parents or guardians are instructed to give the antibiotics right after their healthcare visit) to see if one strategy is more effective than the other. Participants will be randomly assigned to either the immediate antibiotic group or the SNAP group at enrollment. Participation lasts 14 days with follow-up surveys at 4, 7, and 14 days after enrollment.

Antimicrobial resistance (AMR), considered one of the greatest global threats by the WHO, justifies the development of initiatives to promote appropriate antibiotic use-especially in primary care, where most antibiotics in France are prescribed and where misuse remains common. We are proposing a cluster-randomized controlled trial to evaluate the effectiveness of a bimodal intervention combining: (1) improved communication about the circulation of respiratory viruses, and (2) strengthened collaborative practices between general practitioners and pharmacists through a multidisciplinary protocol aimed at verifying that prescribed treatment durations comply with guidelines. The study will include six primary care practices (24 physicians), with three practices in each study arm. The aim of this project is to assess whether the bimodal intervention can reduce the duration of antibiotic treatments for upper and lower respiratory tract infections. The first component (a "viral infection prescription" tool) focuses on reducing unnecessary treatment initiation, while the second (pharmacist-led review) aims to shorten excessive prescription durations.

This multicentric, prospective study aims at: evaluating the prevalence, etiology, characteristics, and 1one-year outcomes of immunocompromised patients hospitalized for Community-Acquired Pneumonia (CAP); conducting biochemical, microbiological and genetic analysis on collected samples.

Community-acquired pneumonia (CAP) is among the most common reasons for emergency department (ED) visits. A clear understanding of the likely pathogens is essential for the rapid institution of adequate antimicrobial therapy. Due to the indistinguishable clinical symptoms between viral and bacterial pathogens, patients with viral respiratory infection are usually under-evaluated while unnecessary antibacterial agents are more likely to be administered. With the development of highly sensitive end-to-end point-of-care (POC) multiplex PCR system, rapid diagnosis of respiratory pathogens for CAP in the ED becomes possible. Our previous NTUH-VGH cooperative research project demonstrated POC respiratory viral testing' in conjunction with procalcitonin test can reduce the length of hospital stay and antibiotic consumption. However, viral testing alone cannot guide precision antimicrobial treatment. A complete pneumonia pathogen testing panel should include bacteria, virus, atypical pathogens, and resistant genes. In addition, such test need to be completed within about time at a reasonable cost. The difficult missing has been recently achieved. The BIOFIRE®FILMARRAY® Pneumonia Panel is the only FDA approved mPCR test that can test 18 bacteria (11 Gram negative, 4 Gram positive and 3 atypical), 7 antibiotic resistance markers, and 9 viruses in one test within 45 minutes. Currently, the world is eagerly to learn how this new diagnostic technology can transform the clinical management of pneumonia. With this in mind, the aim of this study is to evaluate the impact of POC pneumonia pathognome wide testing on the antimicrobial use and outcome of patients. We will perform an open label pragmatic parallel comparison between patients with/without the test. The results will inform the pneumonia guideline. Subsequent health economic analysis based on this study will be important to the reimbursement policy of the health insurance of Taiwan.
