| Abstract | ||||
| Introduction Worldwide, sepsis is one of the leading causes of morbidity and mortality. Patients are at high risk for irreversible organ failure and a lethal course. About 60 000 individuals die from sepsis annually, and survivors have a reduced quality of life. In addition, sepsis places a considerable economic burden on the society. Early and comprehensive treatment improves outcome significantly. Brain natriuretic peptides (BNPs) are powerful predictors of death and major events in patients with stable coronary disease and pulmonary embolism. Several prospective studies have been carried out to investigate the potential role of BNPs in predicting mortality in septic patients in ICUs. The aim of this prospective study was to evaluate BNP for the prediction of mortality and myocardial dysfunction in severe sepsis and septic shock. Patients and methods This prospective study was carried out on 50 patients including group I, patients with sepsis, group (II), patients with severe sepsis, and group III, patients with septic shock. This study was carried out in the ICU of the Internal Medicine Department, Al-Zahraa University Hospital, in the period between January 2013 and March 2014 with written consents from our patients according to the ethical committee of the university. BNPs were determined by enzyme-linked immunosorbent assay. Results There was a highly statistical difference in the mean±SD of the BNP levels in group III (901.77±259.6) compared with group II (610.84±102.46), value less than 0.01; also, there was a statistical difference in the BNP levels in group III (901.77±259.6) compared with group I (217.4±81.16), value less than 0.01, whereas there was a statistically significant difference in group II (610.84±102.46) compared with group I (217.4±81.16), value less than 0.05. In terms of the correlation between the BNP levels and other parameters of the patient groups, there was a highly positive significant correlation between BNP levels and the acute physiology and chronic health evaluation (APACHE II) score, the Sequential Organ Failure Assessment score, and white blood cells count. A significant positive correlation was found between BNP levels and prothrombin concentration (PC). There was a nonsignificant correlation between BNP and age, creatine phosphokinase, creatine kinase-MB, serum glutamic oxaloacetic transaminase, serum glutamic pyruvic transaminase, prothrombin time, international normalized ratio, and length of stay. Conclusion Our results suggested that an elevated BNP level may prove to be a powerful predictor of mortality in patients with sepsis. Future larger and more adequately powered prospective studies are warranted to clarify the prognostic value of BNPs in conjunction with other biomarkers. | ||||
