The Role of Neutrophil-Lymphocyte Ratio and Platelet-Lymphocyte Ratios in Predicting H Pylori Positivity and Severity in Patients with Chronic Gastritis

Objective: Chronic gastritis is one of the most common diseases in the World. It is estimated that more than half of the World's population will have chronic gastritis at any time in life. H pylori are the most common cause of chronic gastritis. In the previous studies, WBC, neutrophil, lymphocyte, PLT, and mean platelet volume (MPV) values and their ratios are used as inflammatory indicators. Neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR) is among the most critical indicators. This study aimed to show whether there is a relationship between H pylori positivity and severity and these parameters in patients who underwent Upper Gastrointestinal system endoscopy.
Method: The files of 1689 patients who underwent upper gastrointestinal endoscopy were scanned for this study. According to laboratory results and pathology reports, the patients were divided into H pylori positivity and non-H pylori positivity. The hemogram results of the patients in both groups were examined, and neutrophil, lymphocyte, thrombocyte values were recorded. NLR and PLR were calculated.
Results: 722 (42.7%) of the patients were male, and 967 (57.3%) were female. While H pylori were positive in 838 (49.6%) patients, 851 (50.4%) patients did not have H pylori positivity. Among H pylori-positive patients, 407 patients (48%) had mild, 280 (33%) moderate H pylori positivity, and 151 patients (19%) had severe H pylori positivity. When the patients were divided into mild, moderate, and severe groups according to H pylori positivity, NLR and PLR were statistically significantly lower as H pylori severity increased. On the other hand, when both groups were compared according to H pylori positivity, no statistically significant difference was found between the two groups in terms of age, albumin, AST, ALT, WBC, Neutrophil, PLT, NLR, PLR values.
Conclusions: Our study found that NLR and PLR values were statistically significantly lower as H pylori severity increased. Therefore, when we evaluate our results in light of the literature, we assume that it is more appropriate to use PLR and NLR values together rather than separately as inflammatory markers regarding H pylori severity.
