Background and aim: In this study, we aimed to investigate the neutrophil/lymphocyte (N/L) ratio, variations in leukocytes and leukocyte subtypes, and the relationship between N/L ratio and insulin resistance (IR) in obesity. Materials and Methods: Ninety six patients and 40 healthy controls were included in this study. Patients’ blood glucose levels, insulin levels, and hemogram parameters upon 8 hours of fasting were determined. Body mass index (BMI) and homeostasis model assessment insulin resistance (HOMA-IR) values were calculated. Results: Neutrophil numbers were found to be higher among IR obese patients than among non-IR obese patients. The N/L ratio was, moreover, found to be higher among IR obese patients, when compared to non IR obese. A positive correlation was found between insulin resistance and both neutrophil and WBC counts. Another positive correlation was also found between insulin levels and the N/L ratio, WBC, and neutrophil counts. Discussion: In our study, leukocyte numbers and subtypes were determined to be higher among obese individuals than among healthy individuals. The N/L ratio had increased significantly only among obese patients who have insulin resistance. Further studies are needed in order to better demonstrate the relationship between the N/L ratio and insulin resistance/inflammation.

BackgroundDiabetes mellitus is closely related to pancreas cancer. In this study we aimed to investigate the effect of hyperglycemia on tumor and inflammation markers, as well as pancreatic exocrine functions.MethodsA total of 98 consecutive diabetic patients with poor glycemic control, and 50 healthy controls were included in the study. We measured hsCRP, erythrocyte sedimentation rate (ESR), CA19-9, CEA, amylase and lipase in addition to routine biochemistry tests, before and after euglycemia was achieved.ResultsFasting blood glucose, HbA1c, CA19-9, CEA, hsCRP, ESR, triglycerides, AST, ALT, GGT, ALP, total cholesterol and LDL-C levels decreased significantly with the regulation of glycemic control. Amylase and lipase levels increased with the regulation of glycemic control. After glycemic control, CA19-9 and CEA levels were still higher, whereas amylase and lipase levels were still lower in the diabetic group compared with the control group. Basal HbA1c showed significant correlation with CA19-9, CEA, amylase and lipase.ConclusionsWe propose to repeat observations of tumor markers after hyperglycemia is resolved, in order to avoid unnecessary invasive tests. Our data also suggest that pancreatic exocrine function was improved with lowering blood glucose in a short period of time.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
