Non-dipper blood pressure (NDP) as an indicator of autonomic dysfunction could be associated with hypertensive response to exercise (HRE) in diabetic patients. HRE was determined as a predictor of development of unborn hypertension. We aimed to investigate if any correlation among NDP and HRE in normotensive type 2 diabetic patients. A total of 59 consecutive type 2 diabetic patients without history of hypertension and with normal blood pressure (BP) on ambulatory blood pressure monitoring (ABPM) were enrolled to the study. We divided the study population in to two groups depending on their BP on ABPM as dipper (group 1) or non-dipper (group 2). There were 22 patients (mean age 49.5?±?7 and 10 male) in group 1 and 37 patients (mean age 53.1?±?10 and 14 male) in group 2. Daytime diastolic and mean BP of dippers and night time systolic and mean BP of non-dippers were significantly higher. HRE was not significantly different between groups (59% vs. 62%, p?=?0.820). Hemodynamic parameters during the exercise test were similar. At multivariate linear regression analysis, resting office systolic blood pressure (SBP) (r?=?0.611, p?0.001), male sex (r?=?0.266, p?=?0.002) and age (r?=?0.321, p?=?0.010) were independently correlated with peak exercises SBP. Logistic regression analyses identified the resting office SBP (OR 1.191, 95% CI 1.080–1.313; p?0.001) and age (OR 1.161, 95% CI 1.038–1.298; p?=?0.012) were independent predictors of HRE. This study revealed that HRE is not related with non-dipper BP in diabetic patients. This study could inspire to further studies to explore the main reasons of HRE in diabetes mellitus. 相似文献

Objective: Although there have been extensive investigations on neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR) and mean platelet volume (MPV) in many diseases, their roles in systemic lupus erythematosus (SLE) remain unclear. The purpose of the present study was to evaluate NLR, PLR, and MPV levels in adult SLE patients and explore their clinical significance.Methods: A retrospective study involving 154 adult SLE patients and 151 healthy controls was performed. All clinical characteristics of the SLE patients were extracted from their medical records. NLR, PLR, and MPV levels between SLE patients and healthy controls were compared, and correlations between these indexes and clinical characteristics were analyzed.Results: Increased NLR, PLR, and MPV were observed in SLE patients. NLR was positively correlated with C-reaction protein (r?=?0.509, p?<?0.01), erythrocyte sedimentation rate (r?=?0.610, p?<?0.01), and SLE Disease Activity Index (SLEDAI) scores (r?=?0.471, p?<?0.01). PLR was positively correlated with SLEDAI scores (r?=?0.44, p?<?0.01). SLE patients with nephritis had higher NLR and PLR levels than those without nephritis (p?<?0.01, p?=?0.03). In addition, an NLR level of 2.065 was determined as predictive cut-off value of SLE (sensitivity 74.7%, specificity 77.5%, AUC?=?0.828). Multiple regression analysis suggested that NLR was independently associated with SLE disease activity.Conclusions: NLR and PLR could reflect inflammatory response and disease activity in SLE patients. 相似文献

Aim of the work: To evaluate the value of three hematological indices to determine subclinical inflammation in Familial Mediterranean Fever (FMF) patients during attack-free period. Patients and methods: This study included 60 FMF patients without FMF-related symptoms or signs in the preceding month and 50 age and sex matched healthy control. Subclinical inflammation was defined as the presence of elevated C-reactive protein (CRP) > 5 mg/dL and/or serum amyloid A (SAA) levels > 6.4 mg/L in the absence of any FMF related clinical signs and symptoms. The neutrophil/lymphocyte ratio (NLR), the platelet/lymphocyte ratio (PLR) and mean platelet volume (MPV) were evaluated. Results: The median age of the patients was 32 and 80% were females. They were 12 (80%) with subclinical inflammation and 48 (80%) without. Mutations of MEFV gene were analyzed in 43 (56.6%) patients and were homozygous in 21, heterozygous in 12 and compound heterozygous in 10. The most common mutation was of M694V. The NLR and PLR were significantly higher and MPV lower in patients with inflammation (p = 0.002, p = 0.02, p = 0.03, respectively) but was comparable to the values in the control. Only NLR was significantly higher in those with inflammation compared to those without (p = 0.009) whereas MPV and PLR were similar (p = 0.45 and p = 0.22, respectively). The best cut-off value for NLR in predicting subclinical inflammation in patients was 2.94 (sensitivity 66.7%, specificity 94.9%;p = 0.009). Conclusions: Only NLR increased in FMF patients with subclinical inflammation which may be used as a marker in determining early activity or flare in addition to other markers. 相似文献

Aims: Non-dipper hypertension is associated with increased cardiovascular morbidity and mortality. Several studies have suggested that the interval from the peak to the end of the electrocardiographic T wave (Tp-e) may correspond to the transmural dispersion of repolarization and that increased Tp-e interval and Tp-e/QT ratio are associated with malignant ventricular arrhythmias. The aim of this study was to evaluate ventricular repolarization by using Tp-e interval and Tp-e/QT ratio in patients with non-dipper hypertension.Materials and method: This study included 80 hypertensive patients. Hypertensive patients were divided into two groups: 50 dipper patients (29 male, mean age 51.5?±?8 years) and 30 non-dipper patients (17 male, mean age 50.6?±?5.4 years). Tp-e interval and Tp-e/QT ratio were measured from the 12-lead electrocardiogram. These parameters were compared between groups.Results: No statistically significant difference was found between two groups in terms of basic characteristics. In electrocardiographic parameters analysis, QT dispersion (QTd) and corrected QTd were significantly increased in non-dipper patients compared to the dippers (39.4?±?11.5 versus 27.3?±?7.5?ms and 37.5?±?9.5 versus 29.2?±?6.5?ms, p?=?0.001 and p?=?0.01, respectively). Tp-e interval and Tp-e/QT ratio were also significantly higher in non-dipper patients (97.5?±?11.2 versus 84.2?±?8.3?ms and 0.23?±?0.02 versus 0.17?±?0.02, all p value <0.001).Conclusion: Our study revealed that QTd, Tp-e interval and Tp-e/QT ratio are prolonged in patients with non-dipper hypertension. 相似文献

AbstractObjective: Patients with a lack of nocturnal decline in blood pressure (BP) are at an increased risk for cardiovascular events. Mean platelet volume (MPV) and soluble CD40 ligand (sCD40L) are accepted biomarkers of platelet activation and considered as a risk factor for cardiovascular disease. The aim of this study was to determine whether MPV and sCD40L levels are higher in non-dipper hypertensive (NDHT) patients than in dipper hypertensive (DHT) patients and healthy controls.Methods: 124 consecutive patients were included to this study. Patients were divided into three groups: NDHT patient group [n?=?43; mean age 51.8?±?6.6; 31?males (72.1%)]; DHT patient group [n?=?41; mean age 50.2?±?7.3; 22?males (53.7%)]; and normotensive group [n?=?40; mean age 49.9?±?6.7; 22?males (55%)]. Physical examination, laboratory work-up and 24-h ABPM were performed for all participants.Results: The sCD40L and MPV levels were significantly higher in the NDHT group than in the DHT and normotensive groups (p?<?0.05). In correlation analysis, MPV, 24-h systolic blood pressure (SBP), 24-h diastolic blood pressure (DBP), night-time SBP and night-time DBP were positively correlated with sCD40L.Conclusion: Our study demonstrated that MPV and sCD40L levels were significantly higher in NDHT patients compared to DHT and normotensive patients. sCD40L levels were positively correlated with MPV, 24-h SBP, 24-h DBP, night-time SBP and night-time DBP. 相似文献

Objective: In this study, left atrial appendage (LAA) flow velocities of dipper and nondipper hypertensive patients were compared with normal subjects. Methods: Twenty‐three patients with nondipper hypertension (NDH), 25 patients with dipper hypertension (DH), and 25 control subjects with comparable age, gender, and body mass indices were enrolled in the study. A detailed history, physical examination, and routine laboratory tests were obtained on all participants. Standard transthoracic echocardiographic examinations were performed on each subject. In addition, LAAs of all patients were visualized using transesophageal echocardiography. LAA filling and ejection velocities were measured using pulsed‐wave Doppler with the sample volume placed in proximal third of the LAA. The mean LAA ejection velocity in patients with NDH (47.7 + 13.0 cm/sec) was found to be significantly lower relative to the DH (66.3 + 12.9 cm/sec) and the control group (81.7 + 8.0 cm/sec) (P < 0.001). The mean LAA filling velocity in patients with NDH (41.7 + 14.7 cm/sec) was also significantly lower relative to those observed in the DH 58.8 + 9.2 cm/sec) and the control group (67.2 + 7.9 cm/sec) (P<0.001). Conclusion: In NDH patients, LAA filling and ejection flow rates are decreased relative to DH patients and the control group. For patients with NDH detected using ambulatory blood pressure monitoring, more aggressive treatment approach should be considered. Maintenance of LAA function may prevent potential complications secondary to left atrial appendage dysfunction. (Echocardiography 2012;29:391‐396) 相似文献

BackgroundPrevious studies have assessed the association of neutrophil to lymphocyte ratio (NLR) with cognitive impairment (COI) in clinical settings. Whether NLR is associated with COI among free-living seniors at population level remains unknown.ObjectivesWe aimed to assess the relationship between NLR and COI among community-dwelling older adults and the predictive value of NLR for COI screening in the community.MethodsData of 4579 older adults aged 60 or older in Weitang Geriatric Diseases study, a community-based cross-sectional study conducted in Suzhou located in the east part of China, were analyzed. The NLR was calculated as the absolute neutrophil count divided by the absolute lymphocyte count. Cognitive function of the participants was assessed using the Abbreviated Mental Test.ResultsCompared to those in the first quartile of NLR, older adults in the 4th quartile of NLR had a greater risk of COI (odds ratio = 1.34, 95 % confidence interval = 1.06–1.69). Elevated NLR quartile was associated with increasing risk of COI (p value for trend = 0.02). Addition of NLR to the conventional risk factors model could improve the correct reclassification of COI about 9.0 % (p = 0.02) and integrated discrimination improvement value was 0.0012 (p = 0.09).ConclusionsWe found that elevated NLR was associated with an increased risk of COI and whether NLR may act as a clinically relevant predictor for COI among community-dwelling older adults could not be determined. 相似文献

BACKGROUND Hepatocellular carcinoma(HCC) is a frequent cause of cancer related death globally. Neutrophil to lymphocyte ratio(NLR) and albumin bilirubin(ALBI) grade are emerging prognostic indicators in HCC.AIM To study published literature of NLR and ALBI over the last five years, and to validate NLR and ALBI locally in our centre as indicators of HCC survival.METHODS A systematic review of the published literature on PubMed of NLR and ALBI in HCC over the last five years. The search followed the guidelines of the preferred reporting items for systematic reviews and meta-analyses. Additionally, we also investigated HCC cases between December 2013 and December 2018 in our centre.RESULTS There were 54 studies describing the relation between HCC and NLR and 95 studies describing the relation between HCC and ALBI grade over the last five years. Our local cohort of patients showed NLR to have a significant negative relationship to survival(P = 0.011). There was also significant inverse relationship between the size of the largest HCC nodule and survival(P = 0.009). Median survival with alpha fetoprotein(AFP) 10 KU/L was 20 mo and with AFP 10 KU/L was 5 mo. We found that AFP was inversely related to survival, this relationship was not statically significant(P = 0.132). Mean survival for ALBI grade 1 was 37.7 mo, ALBI grade 2 was 13.4 months and ALBI grade 3 was 4.5 mo. ALBI grades performed better than Child Turcotte Pugh score in detecting death from HCC.CONCLUSION NLR and ALBI grade in HCC predict survival better than the conventional alpha fetoprotein. ALBI grade performs better than Child Turcotte Pugh score. These markers are done as part of routine clinical care and in cases of normal alpha fetoprotein, these markers could give a better understanding of the patient disease progression. NLR and ALBI grade could have a role in modified easier to learn staging and prognostic systems for HCC. 相似文献

Polycystic ovary syndrome (PCOS) is associated with low-grade chronic inflammation.This was a retrospective case–control study.In the present study, the risk coefficients of neutrophil to lymphocyte ratio (NLR), high-sensitive C-reactive protein (hs-CRP), and mean platelet volume (MPV) in obese patients with PCOS were determined. This study was designed to investigate NLR, hs-CRP, and MPV levels in 68 obese patients with PCOS and 44 nonobese patients with PCOS, and our study group was matched with 47 obese and 43 nonobese controls, respectively.PCOS group had higher MPV, NLR, insulin, glucose, and HOMA-IR rates than those of the controls. Subgroup analyses revealed that the obese PCOS group had higher NLR, hs-CRP, and MPV levels compared to those of controls. The obese PCOS group had higher NLR, hs-CRP, and MPV levels compared to those of the nonobese PCOS group. The odds ratios and 95% confidence intervals of those variables (NLR, hs-CRP, MPV) were found significant (P < .05). NLR, hs-CRP, and MPV variables were found statistically significant in the analysis of receiver operating characteristics.Our study demonstrated that NLR, hs-CRP, and MPV levels are increased in patients with obese PCOS. 相似文献

ObjectivesTo investigate the role of neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) as activity markers in systemic lupus erythematosus (SLE) without nephritis and lupus nephritis (LN) patients.Patients and methodsThis study included 60 SLE patients with LN, 60 SLE patients without renal involvement and 30 healthy controls. We analyzed correlations between NLR and PLR and both disease activity and renal affection.ResultsThe NLR of SLE patients was much higher than those of the controls. Both ratios showed significantly increased values in SLE patients with active disease. NLR and PLR were positively correlated with SLEDAI, ESR, and CRP and negatively correlated with C4. SLE patients with LN had higher levels of NLR than those without nephritis. NLR showed positive correlations with BUN, serum urea, serum creatinine and 24 h urinary protein. We found NLR to be related to anti-ds-DNA level and renal biopsy classes. While PLR was related only to anti ds-DNA. The best NLR to predict SLE active disease was 2.2 and the best PLR cut-off value was 132.9.ConclusionNLR and PLR are useful inflammatory markers to evaluate disease activity in SLE patients. Also, NLR could reflect renal involvement in SLE patients and is associated with the different classes of its histological staging. 相似文献

Objective
The aim of this study was to investigate whether neutrophil to lymphocyte ratio (NLR) was an independent predictor for all-cause mortality or cardiovascular events in patients undergoing angiography or cardiac revascularization with observational studies by meta-analysis.Methods
Pubmed and Embase were searched without language restrictions for cohort studies published prior to November 2013. Citations were independently screened by 2 authors, and those meeting the inclusion criteria defined a priori were retained. Data on authors, year of publication, location, target participant, comparison of NLR, outcome assessment, number of event and sample size, duration and statistical adjustments were abstracted.Results
Eight studies were identified that reported on all-cause mortality and five studies were identified that reported on cardiovascular events. The pooled relative risk (RR) of all-cause mortality was 2.33 (95% CI 1.88–2.88) and the RR of cardiovascular events was 1.89 (95% CI 1.42, 2.52) comparing the highest with the lowest category of NLR.Conclusions
The meta-analysis indicates that NLR is a predictor of all-cause mortality and cardiovascular events. Further well-designed trials are warranted to confirm this association. 相似文献20.
目的:探讨冠心病合并高血压患者的冠状动脉病变与血压昼夜节律的关系。方法:选取2013年1月~2015年12月于我院行冠状动脉造影诊断为冠心病且合并高血压的患者154例。通过对所有患者进行24h动态血压监测,分析动态血压参数,根据夜间血压下降率分为勺形高血压组(DH组,n=71)和非勺形高血压组(NDH组,n=83)。比较两组患者基本临床资料、实验室指标。冠脉造影示管腔狭窄≥50%定义为冠脉病变,根据病变累及部位分为单支、双支(累及左主干纳入双支病变)及三支病变组。按照Gensini评分标准对每位患者的冠脉病变程度进行定量评定。结果:NDH组急性冠脉综合征发生率明显高于DH组(P<0.05)。NDH组患者夜间平均收缩压(nMSBP)、夜间平均舒张压(nMDBP)均明显高于DH组,夜间血压下降率(包括收缩压和舒张压)明显低于DH组(P<0.001)。两组患者冠状动脉病变部位比较无明显差异(P>0.05),但NDH组冠脉三支病变发生率、病变支数、Gensini积分均显著高于DH组(P<0.05)。结论:冠心病合并非勺形高血压患者相比于勺形高血压患者冠状动脉病变范围更广,病变程度更重,急性冠脉综合征发生率更高,具有更高的致死风险。 相似文献
