Association Between Plasma D Dimer in Adult CAP and Severity of Inflammatory Response and Survival

Association Between Elevated Plasma D-dimer in Adult Community-acquired Pneumonia Patients and Severity of Inflammatory Response and Survival

• Status: Recruiting
• Phase: —
• Study type: Observational
• Enrollment: 50 (estimated)
• Sponsor: Ain Shams University · Academic / Other
• Sex: All
• Age: 18 Years
• Healthy volunteers: Not accepted

Summary

This observational study aims to investigate the association between elevated plasma D-dimer levels and the inflammatory response, as well as its impact on survival in adult patients with community-acquired pneumonia. the study participants will be subjected to sampling for D-dimer and calculation of CURB-65 score. this aims to find the relation between them

Detailed description

Community-acquired pneumonia (CAP) is a common and potentially life-threatening infection that affects millions of individuals worldwide each year. D-dimer is a fibrin degradation product that is elevated in many conditions associated with inflammation and coagulation activation, including pneumonia. This is an observational study including a minimum of 50 patients with CAP Patients who will be admitted to the Chest department, or coming to the outpatient clinic at Ain-Shams University Hospitals with CAP, and have the following inclusions: 1. age ≥18 years 2. diagnosis of CAP based on clinical symptoms, laboratory findings, and radiological evidence. 3. Did not have any clinical or radiological signs suggesting COVID-19 pneumonia Exclusion criteria Patients with a history of coagulation disorders, cancer, or other chronic diseases, or refusal to participate. All patients will be subjected to the following: - 1. Full medical history, demographics 2. Thorough clinical examination. 3. laboratory values (including white blood cell count, CRP, and D-dimer), With pre and post sample known precautions (8). 4. Radiological findings (CXR). 5. Severity of illness (based on the CURB-65 score).
