Quantitative Relationships between Circulating Leukocytes and Certain Enteric Bacterial Infection in Children with Acute Diarrhea

Abstract

Various pathogenic microorganisms have been implicated as the cause of infectious diarrhea in children as a result of water and food contamination. The study's goal is to determine the reliability of complete blood count (CBC) in peripheral blood of children with acute diarrhea which infected by certain enteric bacteria, with an emphasis on leukocytes (WBCs). A study conducted to examine the pattern of bacterial distribution in children with acute diarrhea's stool, as well as the relationship between the presence of pathogenic bacteria in stool samples and the number of total WBCs and differential leukocyte count in peripheral blood. Samples size includes (76) of health none diarrhea and (174) diarrheal patients, statistical analysis revealed that co-infection by E. coli and Klebsiella sp. was significantly higher (P<0.001) among children which suffered by diarrhea in compare to health individuals. In addition, the logistic regression shows co-infections and infections by Klebsiella sp. (OR: 29.44, 16.288 respectively) more likelihood leads to acute diarrhea compare to E. coli infection alone (P<0.001). Neutrophils/ Lymphocyte ratio (NRL) was (2.412) times higher and neutrophils (1.069) times more in diarrheal group (P<0.001), also the AUC for NRL was 0.833(sensitivity: 81.61 and specificity: 68.42), while for percent of neutrophils was less 0.671 (sensitivity: 46.24 and specificity: 85.71). Concluded that peripheral leukocyte count, particularly the NRL index, is helpful in children with acute diarrhea and additionally that the prevalence of diarrhea is altered by different bacterial infections.
