Specificity, Sensitivity and Usefulness Of Neutrophil Lymphocyte Ratio In The Follow-Up Of Patients After Helicobacter Pylori Eradication Treatment

Objective: The aim of this study is to determine the sensitivity and specificity of the NLR ratio in order to assess treatment effectiveness in the follow-up of patients who are endoscopic H. pylori-positive and administered eradication therapy. Materials and Methods: The Endoscopy Unit at Istanbul Medipol University Pendik Hospital evaluated 386 individuals who underwent upper gastrointestinal endoscopy. Neutrophil and lymphocyte counts, as well as neutrophil-to-lymphocyte ratios (NLR), were compared in HP positive and negative patients. H. pylori eradication was performed on 205 HP-positive patients using a 2-week triple therapy. All patients had a complete blood count done at the same time, and NLR was computed and compared between the eradicated and non-eradicated groups. Results: H. pylori eradication was accomplished in 100 (48.7%) of the patients, whereas the stool antigen test was positive in 105 (51.3%) of the patients. There was a statistically significant difference in neutrophil counts (P
