Reason Evaluation of Initial Treatment Failure in Patients With CAP
Community-acquired PneumoniaThis research is to evaluate the effect of different antibiotics (Moxifloxacin Hydrochloride and Sodium Chloride Injection vs. β-lactam antibiotics for injection +/- Azithromycin for Injection) on the early deterioration or progression (<72 h of treatment) of community acquired pneumonia and to study the effect of the early deterioration or progression on the prognosis of community acquired pneumonia.
MACCE in Hospitalized Patients With Community-acquired Pneumonia
Community-acquired PneumoniaCommunity-acquired pneumonia is the most common infection leading to hospitalization in intensive care units and the most common cause of death associated with infection disease. Epidemiological studies have shown that respiratory tract infections are associated with an increased risk for the development of acute cardiovascular and cerebrovascular events. This link is further supported by studies indicating that influenza vaccination is associated with a reduced risk of hospitalization for pneumonia as well as heart disease and cerebrovascular disease. Data connecting acute respiratory tract infections and cardiovascular events stem almost exclusively from cross-sectional or retrospective studies. Thus the real incidence and the prognostic impact of AMI, as well as the pathophysiological relationship between pneumonia and cardiovascular damage is still elusive. Inflammation plays a major role in the pathogenesis of coronary artery disease. The increased concentrations of proinflammatory cytokines together with the activation of coagulation, the down-regulation of anticoagulant mechanisms and the enhanced platelet aggregation may trigger atheroma's instability, plaque rupture and thrombus formation. Inflammation and coagulopathy are also considered universal host responses to infection in patients with severe sepsis. Thus far limited data are available on the changes in these high regulated systems, together with platelet activity in patients with CAP and their potential relationship with cardiovascular risk. This project will consist in a prospective multicenter study to investigate the incidence of major adverse cardiac and cerebrovascular events (MACCE) in hospitalized patients with CAP, its prognostic relevance and the potential relationship between enhanced cardiovascular risk and the activation of inflammation, coagulation and platelet aggregation in this setting.

Observational Study of Sepsis and Pneumonia to Develop Diagnostic Tests
SepsisSepticemia4 moreWe propose to develop novel diagnostic tests for severe sepsis and community acquired pneumonia (CAP). This program, entitled Community Acquired Pneumonia & Sepsis Outcome Diagnostics (CAPSOD), is a multidisciplinary collaboration involving investigators at six organizations: NCGR; Duke University Medical Center, Durham, NC; Henry Ford Hospital, Detroit, MI; Eli Lilly and Company, Indianapolis, IN; Indiana Centers for Applied Protein Sciences, Indianapolis, IN; and ProSanos Corp., La Jolla, CA. In the United States, Community Acquired Pneumonia is the sixth leading cause of death and the number one cause of death from infectious diseases. Of the 5.6 million annual cases of CAP, 1.1 million require hospitalization for intensive therapy. Sepsis, commonly known as blood poisoning or bloodstream infection, is the tenth leading cause of death in the US and the number one cause of death in non-cardiac intensive care units. Incidence of sepsis is increasing by 9% each year and mortality rates vary between 25 and 50%. Cost to the US healthcare system exceeds $20 billion each year. In patients with suspected sepsis or early CAP, rapid identification of patients who will develop severe sepsis or CAP is critical for effective management and positive outcome. The CAPSOD study is designed to identify novel tests for early diagnosis of severe sepsis and CAP. When performed in patients at the earliest stages of disease, these tests will have prognostic value, rapidly identifying those who will have poor outcomes or complicated courses. CAPSOD will prospectively enroll patients with sepsis and CAP at Duke University Medical Center and Henry Ford Hospital. The study will use advanced bioinformatic, metabolomic, proteomic and mRNA sequencing technologies to identify specific protein changes, or biomarkers, in patient blood samples that predict outcome in sepsis and CAP. Development of biomarker-based tests will permit patient selection for appropriate disposition, such as the intensive care unit, and use of intensive medical therapies, thereby reducing mortality and increasing effectiveness of resource allocation.
Beta-Lactams Dosing In Pneumonia in ICU in Patients Treated by Continuous Renal Replacement Therapy:...
Beta-lactamContinuous Renal Replacement Therapy2 morePneumonia are the most frequent infections in ICU. Little is known about beta-lactam doses necessary for this infection for patients treated with continuous veino-veinous hemodialysis. The pharmacokinetic variability expose to over and underdosage leading to toxicity or therapeutic failure. The aim of this study is to define if beta-lactams doses used in pneumonia for patients with acute kidney injury treated with our hemodialysis conditions lead to beta-lactam therapeutic plasma levels.
Pneumonia Policy Formation in Pakistan
PneumoniaChildhood PneumoniaIn Pakistan, numerous policies have been formulated in the past on pneumonia management translated into various programs. However, despite completion, the state of pneumonia mortality remains unchanged as no sustainable solutions have been yielded by these programs. This is probably because there was no ownership of these policies and programs at the provincial, district and community level. We, therefore, plan to understand pneumonia related policy environment within Pakistan to identify gaps in this system through a two phased study. The first will be qualitative with key informant interviews conducted from relevant stakeholders, e.g, policy makers, practitioners, academicians, researchers etc., to understand how policies are conceptualized. Data will be analyzed through an integrated approach in a software. The second phase will social network research conducted by studying actors linked together by social relations. This will be achieved through net mapping exercise to understand, discuss, and visualize how various actors influence pneumonia related outcomes through technical and financial links. Data will be analyzed through the Organizational Risk Analyzer (ORA) which is a meta-network assessment and analysis tool. This study will be the first of its kind for under-five pneumonia and will guide policy makers for creating effective solutions to combat the disease.

Pneumococcal Nasopharyngeal Colonization as Predictor of Community-Acquired Pneumonia (CAP) in Adults...
Streptococcus Pneumoniae PneumoniaStreptococcus Pneumoniae Infection2 moreStreptococcus pneumoniae (pneumococcus) is a commensal bacterium, often isolated in the nasopharynx of preschool children and older adults with weakened immune systems, a pathogen that remains the leading cause of Community-Acquired Pneumonia (CAP) and invasive pneumococcal disease (IPD) such as Sepsis and Meningitis. CAP is the sixth leading cause of overall mortality and the first cause of infectious disease in Colombia and the world (Montúfar et al, 2013; GBD, 2016; WHO, 2018), and both its incidence and prevalence have remained stable over the past 3 decades. Likewise, CAP due to S. pnemoniae is the most common cause of lower respiratory tract infections in humans worldwide and is associated with high morbidity and mortality in patients who suffer from it. Pneumococcus frequently colonizes the nasopharynx of children and adults and, therefore, this condition has been postulated as a risk factor for the development of CAP. There are reports of the effect of nasopharyngeal colonization in infants, but the implications of this colonization in adults, especially adults with chronic comorbidities, are not known. Additionally, several studies point to a relationship between pathogenicity, colonization capacity, and disease severity according to the infecting pneumococcal serotype. Therefore, it is not known which pneumococcal serotypes are most frequently colonized by adults with chronic diseases (cardiovascular disease (CVD), chronic obstructive pulmonary disease (COPD), renal disease (RHD), rheumatological disease (MDR), Diabetes Mellitus (DM), among others) and the potential clinical implications of this colonization. For these reasons, this research aims to study the phenomenon of colonization by pneumococcus in patients with chronic diseases for the development of CAP, and the relationship between the virulence genes of different serotypes and the outcome in invasive pneumococcal disease (IPD). This study is based on real evidence (from clinical practice) and translational medicine, is prospective-observational, multicenter and cohort type in consecutive patients. Thus, in a first phase the clinical observation of the subjects will be carried out, a second phase of follow-up and sampling in the patients, and a third phase of molecular analysis.
Presepsin Biomarker for Ventilator-associated Pneumonia Diagnosis in COVID-19 Patients
Ventilator Associated PneumoniaCovid19This study is observational and double blind. It evaluates the validity of presepsin (a serum biomarker of bacterial infections) as early biomarker of Ventilator Associated Pneumonia. It will be measured at day 0 (ICU admission) and every 48 hours in every patient with Sars-Cov 2 interstitial pneumonia requiring invasive mechanical ventilation (see inclusion ad exclusion criteria) until Day 30, ICU discharge or ICU death. There will be no change in clinical practice and in pneumonia diagnosis. We will examine how the elevation of presepsin level could be an early marker of ventilator associated pneumonia or a marker of bacterial pneumonia at ICU admission, before the microbiological results or clinical diagnosis.
