Evidence on the role of neutrophils in cardiovascular disease is less compelling. Therefore, we conducted a systematic review of the literature with the aim of identifying all the available evidence to clarify the role of neutrophils (absolute or relative count, neutrophil/lymphocyte ratio) as a prognostic risk factor in patients with ACS and/or cardiac revascularisation. All published studies evaluating the role of neutrophils as a risk factor for clinical outcomes were assessed using the MEDLINE and EMBASE databases. Study selection, data extraction and validity assessment was performed independently by two reviewers. Twenty-one studies (17 of whi...

We sought to determine cellular tumor necrosis factor-alpha (TNF-α) production from peripheral blood mononuclear cells (PBMCs) and interleukin (IL)-8 release from neutrophils (PMNs) in patients studied for suspected OSA. Thirty-six consecutive patients who underwent a nocturnal complete cardiorespiratory evaluation for suspected OSA were initially evaluated. Serum, PBMCs, and PMNs were isolated (at baseline and after 12 weeks) from patients with apnea-ipopnea index (AHI) >20 (OSA group, n = 16) and from control patients with AHI <5 (nonOSA group, n = 11). All patients continued the same pharmacological therapy for 12 weeks; the OSA group was additionally treated with nocturnal continuous positive-airway-pressure ventilation (cPAP). The two groups had similar clinical characteristics (prevalence of hypertension, dyslipidemia, diabetes, and cardio-metabolic therapies) except for obesity. Resting and stimulated TNF-α production from PBMCs and IL-8 release from PMNs were similar in the two groups. Serum cytokines resulted within the normal range. In the OSA group, cPAP was not associated with changes in cellular responses. In patients showing similar prevalence of major cardiovascular risk factors and cardio-metabolic therapies, differing for the presence or absence of OSA, cytokine productions from PBMC and PMN were similar and were not modified during cPAP therapy. Studies designed to investigate OSA-associated inflammation should carefully match the control group subjects.

Subjects at high cardiovascular risk (high-risk subjects, HRS) and healthy controls (HC) were also enrolled. To this end, patients with PAD were studied 1 month before surgery, at the time of surgery, and 3 and 6 months after surgery. Polymorphonuclear leukocytes were obtained from venous blood and evaluated for AT1R expression at messenger RNA (mRNA) and protein level and IL-8 production (by means of enzyme-linked immunosorbent assay). At baseline, AT1R membrane expression was similar in cells from patients with PAD, HRS, and HC, whereas AT1R mRNA was similar in patients with PAD and HC and higher in HRS. During the follow-up period, AT1R expression progressively decreased both on the cell membrane and at the mRNA level. Both resting and stimulated production of IL-8 was lower in patients with PAD in comparison to HC and HRS and did not change during the follow up period. In PAD patients, femoral endarterectomy is associated with reduction of AT1R expression however with no apparent effect on IL-8 production. The relevance of such effects for cardiovascular protection deserves consideration.

The aim of this study was to investigate whether baseline indexes of autonomic modulation of heart rate or baroreflex sensitivity were correlated with cardiovascular reactivity to stress. Spectral parameters of RR interval variability and the LFalpha-index were calculated in a resting condition in 53 untreated subjects (34 hypertensives; 19 normotensives). The reactivity to stress was expressed as changes of mean RR and systolic blood pressure during arithmetic mental stress testing. The cardiovascular reactivity was not correlated with either baseline spectral parameters of RR interval variability or LFalpha-index. In the multivariate analysis no confounding effect of diagnosis (hypertension vs normotension) was found. Moreover no interaction between diagnosis and both LF/HF ratio and LFalpha-index was observed. Thus, the cardiovascular response to a mental stimulus appears to prevail over the baseline pattern of cardiovascular regulation independently of the presence or absence of the hypertensive disease.

The potential modulation of pain sensitivity by thyroid hormones is largely undetermined. Moreover, a few experimental studies show that peripheral benzodiazepine receptors (PBRs), which may be altered in hypothyroidism, seem to be related with pain perception. Dental pain threshold and tolerance were evaluated in 19 patients followed for differentiated thyroid carcinoma (1) in severe short-term hypothyroidism (phase 1) and (2) during thyroid stimulating hormone-suppressive LT4 treatment (phase 2). PBR expression (cytofluorimetric evaluation) on peripheral blood mononuclear cells was also investigated in the 2 phases. Pain perception differed throughout the study, the dental pain threshold was higher in phase 1 (P<0.05) whereas pain tolerance was higher but not significantly (P=0.07). Although the systolic blood pressure was higher during hypothyroidism (P<0.01), no relationship was found between blood pressure changes and pain sensitivity variations. Moreover, the multiple regression analysis showed an independent association of the clinical phase with pain sensitivity (r=-2.61, P=0.029), while accounting for systolic blood pressure. The intensity of PBRs was significantly higher in the first phase of the study (P=0.047) whereas the ratio did not significantly differ. However, no relationship was observed between pain sensitivity and PBRs. In conclusion, in athyreotic patients, the pain sensitivity is related to the thyroid status and is independent of the increase in blood pressure induced by thyroid hormone deprivation. The PBRs do not seem to have major influence on pain sensitivity changes in hypothyroidism.

Angiotensin II (Ang II) type 1 receptor (AT1R) mediates the pro-atherogenic effects of Ang II whereas the type 2 receptor (AT2R) seems associated with atheroprotection. We sought to investigate the potential changes of AT1R-AT2R expression in human monocytes of type 2 diabetic- hypercholesterolemic patients and in hypercholesterolemic subjects, upon clinical treatment with rosuvastatin. Methods The AT1R membrane protein and mRNA AT1R and AT2R expression in monocytes were investigated in 10 type 2 diabetic-hypercholesterolemic patients and in 10 hypercholesterolemic subjects, before and after 3-month rosuvastatin treatment. Moreover, the serum cytokine levels of interferon-γ (IFN-γ) and interleukin-4 (IL-4) were detected. Results As expected, rosuvastatin was associated with a change in the ...

Despite the indication to treat in patients affected by both dyslipidemia and NAFLD, an undertreatment in statin therapy due to the potential liver damage is frequently observed. We sought to evaluate retrospectively the impact of statin on the lipid profile and on the achievement of low-density lipoprotein (LDL) cholesterol targets in relation to the National Cholesterol Education Program--Adult Treatment Panel III-cardiovascular risk in dyslipidemic patients presenting with a clinical--diagnosis of NAFLD and elevated liver enzymes before statin prescription. As a secondary endpoint, the authors investigated whether statin could be associated with changes of liver enzymes. Forty-three patients with dyslipidemic NAFLD presenting with increased values of aspartate aminotransferase and/or alanine aminotransferase and/or γ-glutamyl-transferase at baseline were analyzed retrospectively as regard the lipid profile and liver enzymes (values reported before statin and during statin therapy). Total cholesterol, LDL and triglycerides were significantly reduced at follow-up (5.4 ± 5.4 months). The LDL target was achieved at the second visit in 30 patients (69.8%).The number of patients achieving the LDL target was significantly higher in low-risk group compared with moderate- and high-risk subjects. Liver enzyme levels showed no significant changes between baseline and follow-up. Statin treatment was effective (without changes in liver enzymes) in patients with dyslipidemia and NAFLD and therefore, affected by a profound alteration in lipoprotein metabolism. The number of patients achieving LDL target was related to the Adult Treatment Panel III risk classification, being higher in patients with lower risk.

Patients accessing the ED for HF-related symptoms require fast diagnosis and early treatment. Transthoracic echocardiography has a crucial role in HF diagnosis, but requires qualified staff and adequate time for execution. The measurement of inferior vena cava (IVC) diameter has been recently proposed as a rapid, simple and reliable marker of volume overload. The aim of this systematic review was to assess the accuracy of IVC-ultrasound as a stand-alone test for HF diagnosis in patients presenting to the ED with acute dyspnoea.MethodsStudies evaluating the diagnostic accuracy of the inferior vena cava collapsibility index (IVC-CIx) for HF diagnosis were systematically searched in the EMBASE and MEDLINE databases (up to January 2018). Quality Assessment of Diagnostic Accuracy Studies 2 tool was used for the quality assessment of the primary studies. A bivariate random-effects regression approach was used for summary es...

Thus, the identification of FH patients is crucial to prevent or delay the onset of cardiovascular events, and the availability of a tool helping with the diagnosis in the setting of general medicine is essential to improve FH patient identification. This study evaluated the performance of the Dutch Lipid Clinic Network (DLCN) score in FH patients enrolled in the LIPIGEN study, an Italian integrated network aimed at improving the identification of patients with genetic dyslipidaemias, including FH. The DLCN score was applied on a sample of 1377 adults (mean age 42.9 ± 14.2 years) with genetic diagnosis of FH, resulting in 28.5% of the sample classified as probable FH and 37.9% as classified definite FH. Among these subjects, 43.4% had at least one missing data out of 8, and about 10.0% had 4 missing data or more. When analyzed based on the type of missing data, a higher percentage of subjects with at least 1 missing data in the clinical history or physical examination was classified as possible FH (DLCN score 3-5). We also found that using real or estimated pre-treatment LDL-C levels may significantly modify the DLCN score. Although the DLCN score is a useful tool for physicians in the diagnosis of FH, it may be limited by the complexity to retrieve all the essential information, suggesting a crucial role of the clinical judgement in the identification of FH subjects.
