Role of CBC Parameters in Early Diagnosis of Pediatric Pneumonia

Study Overview
=================
Brief Summary
-----------------
Detection of the role of Complete Blood Count (CBC) parameters in early diagnosis of pediatric pneumonia -Testing the ability of Complete Blood Count (CBC) parameters (N/L ratio, PLT /MPV ratio, MPV and other parameters) to differentiate between viral and bacterial pneumonia.

Detailed Description
-----------------
Pneumonia is the leading cause of hospitalizations and death among children with nearly 120 million new cases and one million deaths every year. Viruses are the main cause of pneumonia in infants and toddlers between 30 days and 2 years old. Children 2 to 5 years old, respiratory viruses are also common with the rise of cases related to S. pneumoniae and H. influenzae type B and other bacterial organisms. Viral pneumonia caused by , respiratory syncytial virus, which are the most common cause of community- acquired pneumonia in children younger than 5 years. Streptococcus pneumoniae is the most common bacterial cause across all age groups. Other important bacterial causes in children younger than 5 years include Hemophilus influenzae, Streptococcus pyogenes, Staphylococcus aureus, and Moraxella catarrhalis. Parapneumonic effusion/empyema (PPE/EP), necrosis of lung parenchyma (NC), and lung abscess (AB), are serious complication of pediatric pneumonia. Because of these serious complications, early diagnosis of the causative organism is very important to start the proper treatment and avoid these serious complications. Complete Blood Picture (CBC) is one of the most important preliminary routine investigations for diagnosis and monitoring of infection. Recently, CBC parameters, especially Total Leucocyte Count (TLC), ANC, and platelet count all showed significant associations with neonatal sepsis. Besides, the TLC,Absolute neutrophils count (ANC), and platelet counts had good sensitivity and specificity in diagnosing neonatal sepsis Another study have assessed the utility of C-reactive protein (CRP), White Cell Count (WCC), Neutrophil/Lymphocyte ratio (N/L), Platelets/ Mean Platelets Volume ratio (PLT/MPV ratio), Mean Platelets Volume (MPV), Monocyte Distribution Width (MDW) and many other CBC ratios to differentiate probable bacterial infections from non-bacterial infections and also assessed the severity of illness. - In this study, we are going to test the role of Complete Blood Picture (CBC) parameters and ratios as an early detection tool of bacterial and viral pneumonia. This might have a role in early prediction and diagnosis of the causative organism. Which in turn leads to rapid intervention, and better prognosis.
