Razões neutrófilos/linfócitos e plaquetas/linfócitos em pacientes diabéticos com ou sem disfunção renal

Abstract

AIMS: To compare the neutrophil/lymphocyte ratio (NLR) and the platelet/lymphocyte ratio (PLR) between patients with and without type 2 diabetes mellitus and between diabetic patients with and without renal dysfunction.METHODS: A cross-sectional retrospective study was performed at the Laboratory of Clinical Analyzes of the Hospital das Clínicas of the Federal University of Goiás between January and December 2016. Data from patients aged 40 years or older were included in the study. Those with a blood glucose ≥200 mg / dL and/or glycated hemoglobin ≥6.5% formed the diabetic group, and those who did not present these criteria for diabetes formed the control group, being matched by age and sex. The diabetic group was classified in one group with renal damage and another without renal damage, according to the 24-hour microalbuminuria. Calculations for NLR and PLR were performed from the absolute number of neutrophils, lymphocytes and platelets, and the medians were compared.RESULTS: A total of 122 subjects were included in the study, among which 52.5% were between 40 and 64 years of age and 63.9% were male. The median NLR was 2.1 (min 0.8 - max 5.3) in the diabetic group and 1.9 (min 0.6 - max 6.2) in the control group (p=0.16). The median PLR was 120.5 (min 63.5 - max 206.6) in the diabetic group and 119.7 (min 40.4 - max 215.1) in the control group (p=0.19). Considering the age group, there was no difference in the median NLR or PLR among the diabetic group and the control group; however, the NLR was higher for individuals 65 years of age or older, regardless of whether they were diabetic (median 2.2, min 1.0 - max 3.8, p=0.01) or not (median 2.4, min 0.9 - max 3.6, p=0.001). Among the participants, 38 patients presented renal damage, 24 (63.1%) of the diabetic group and 14 (36.9%) of the control group. The median NLR and PLR were similar among diabetic patients with renal damage, diabetics without renal damage and control group.CONCLUSIONS: NLR and PLR were similar between the diabetic group and the control group, as well as among diabetics with or without renal damage. RNL was higher for individuals 65 years of age or older, regardless of whether they were diabetic or not.
