Abstract

Introduction: Essential hypertension is an important health condition responsible for conditions such as heart attack, stroke, and kidney disease. Traditional risk factors and their control are important for reducing mortality. Inflammation caused by organ damage plays a role in the undesirable outcomes of hypertension. Biomarkers, such as the systemic immune-inflammatory index (SII), are predictors, but their relationship with risk factors is poorly understood.

Objective: To evaluate the correlation between the SII and risk factors in patients with hypertension.

Methods: This cross-sectional study was conducted in 2020 in Bahia with hypertensive patients from an outpatient clinic. We collected demographic and clinical data such as age, body mass index, and the following biomarkers: low-density lipoprotein level, glomerular filtration rate, interleukin 6 level, C-reactive protein level, neutrophil/lymphocyte ratio (NLR), hemogram, creatinine level, urea level, ferritin level, and vitamin D level.

Results: A total of 61 patients, most of them black women, participated in the study. The prevalence of type 2 diabetes was 19%, and there was no prevalence of stroke or heart attacks. According to the Framingham risk index, a large part of the sample presented high and very high risks. The bivariate analysis between SII and NLR was positive. Multivariate analysis showed that age, renal function, and NLR were positively correlated with the SII. The patients' Framingham risk did not correlate with the SII.

Conclusions: Inflammation is important for vascular damage in arterial hypertension caused by increased oxidative stress. We evaluated SII and NLR as indices of correlation with risk factors. The SII is a lowcost tool that can be used to screen for chronic conditions, such as hypertension. In summary, higher SII was positively associated with older age and worse renal function in patients with high-risk hypertension.

高危高血压患者的全身免疫炎症指数:一项横断面研究
简介:原发性高血压是一种重要的健康状况,可导致心脏病、中风和肾病等疾病。传统的危险因素及其控制对降低死亡率很重要。由器官损伤引起的炎症在高血压的不良后果中起作用。生物标志物,如全身免疫炎症指数(SII),是预测因子,但它们与危险因素的关系尚不清楚。目的:探讨高血压患者SII与危险因素的相关性。方法:这项横断面研究于2020年在巴伊亚州门诊的高血压患者中进行。我们收集了人口统计学和临床数据,如年龄、体重指数和以下生物标志物:低密度脂蛋白水平、肾小球滤过率、白细胞介素6水平、c反应蛋白水平、中性粒细胞/淋巴细胞比率(NLR)、血象、肌酐水平、尿素水平、铁蛋白水平和维生素D水平。结果:共有61例患者参与了研究,其中大多数为黑人女性。2型糖尿病的患病率为19%,没有中风或心脏病发作的患病率。根据Framingham风险指数,很大一部分样本存在高风险和极高风险。SII与NLR的双变量分析呈正相关。多因素分析显示,年龄、肾功能、NLR与SII呈正相关。患者的Framingham风险与SII无关。结论:炎症在氧化应激引起的高血压血管损伤中起重要作用。我们评估了SII和NLR作为与危险因素相关的指标。SII是一种低成本的工具,可用于筛查慢性疾病,如高血压。综上所述,高SII与高危高血压患者的年龄和肾功能恶化呈正相关。
