چکیده
BACKGROUND Pneumonia is the leading cause of death in children. Few studies have explored the predictive value of copeptin in pediatric pneumonia. AIM This study aimed to assess the role of copeptin as a marker of severity of community-acquired pneumonia (CAP). METHODS This prospective case-control study was carried out at Minia University Children's Hospital in Minia (Egypt) from January to December 2016. Eighty children aged from 2 months to 42 months were enrolled in this study and were classified into group 1 (40 children with clinical, laboratory and radiological evidence of pneumonia) and group 2 (40 apparently healthy control). Serum copeptin level was assayed for all enrolled children. RESULTS Mean serum copeptin level was significantly higher in pneumonic patients (985.7±619) pg/ml compared to controls (519±308.2) pg/ml (p<0.001). Serum copeptin was significantly elevated in survivors of pneumonia more than non-survivors (p=0.001). Also, copeptin was significantly higher in the group of non-survivors (1811.8±327.1) compared to 745.4±472.5 for survivors (p=0.01). There was a significant positive correlation between serum copeptin levels and the degree of respiratory distress (p=0.02). CONCLUSION Copeptin seems a reliable and available predictor marker for assessing the severity and prognosis of pediatric community acquired pneumonia.

BACKGROUND Community-acquired-pneumonia is the leading cause of child mortality worldwide. Very few studies have explored the predictive value of Proadrenomedullin and Copeptin in pediatric severe pneumonia and bacteremia. METHODS Proadrenomedullin and Copeptin were assessed as predictors for complicated community-acquired pneumonia (bacteremia, empyema) in 88 children aged 0 to 16 years pres...

OBJECTIVE A high genomic load of Pneumococcus from blood or cerebrospinal fluid has been associated with increased mortality. We aimed to analyse whether nasopharyngeal colonisation density in HIV-infected patients with community-acquired pneumonia (CAP) is associated with markers of disease severity or poor outcome. METHODS Quantitative lytA real-time PCR was performed on nasopharyngeal swab...
متن کاملHyperglycemia and Red Cell Distribution Width for Prediction of Mortality in Preschool Children with Community Acquired Pneumonia (CAP)
Background Community acquired pneumonia (CAP) is a major infectious cause of mortality in preschool children especially in developing countries. Red Cell Distribution Width (RDW) has been associated with poor outcomes of CAP. We aimed to determine whether admission stress hyperglycemia and RDW can predict mortality in preschool children with CAP for early identification of patients at risk of ...
