Relationship between blood components, inflammatory factors and bacterial spp that cause tonsillitis and dental caries in Iraqi children

Aims and Objectives: Study the correlation between anti-streptolysin O titer (ASOT) and C-reactive protein (CRP) with other related factor and the correlation between bacterial species and related with some tested parameter. Materials and Methods: A total of 120 patients were part of the study and was divided into six groups, each group had 20 patients with age range was 6–12 years. Blood sample collection about 10 ml was withdrawn from each patient via vein puncture using 10 ml disposable syringes, 5 ml for immunological study and 5 ml for hematological study. Results: The results of ASOT showed that a highly significant positive correlation with monocytes and a highly negative correlation with eosinophil. As for CRP, it was found it have a highly significant positive correlation with eosinophil, lymphocytes and have a highly negative correlation with neutrophil percentage and monocytes percentage with a positive correlation with erythrocyte sedimentation rate (ESR). Conclusion: Our study shown that ASOT are still useful diagnostic tools for tonsillitis. CRP levels in the tonsillitis patients group were significantly higher than those in other groups, whereas ESR levels in the tonsillectomy patients group were significantly higher than those in other groups.
