Human monocytes can be divided into CD14(++)CD16(-), CD14(++)CD16(+) and CD14(+)CD16(++) cells, which differ in their functional properties. The aim of this study was to examine monocyte subset distribution, monocyte-platelet aggregate (MPA) formation and expression of CCR5, the receptor of the platelet-derived chemokine CCL5, and to determine whether these parameters are altered in individuals with coronary atherosclerosis. MethodsPeripheral blood cells from 64 healthy blood donors (HBDs) and 60 patients with stable coronary artery disease (CAD) were stained with antibodies against CD14, CD16, CD42b and CCR5 and analysed by flow cytometry. Circulating CCL5 levels were determined using an enzyme-linked immunosorbent assay. ResultsIn patients with CAD, the relative proportion of the CD14(++)CD16(-) monocyte subset was elevated (P<0.05) and of the CD14(+)CD16(++) subset was reduced (P<0.001) compared with the HBD group. Furthermore, MPA formation significantly increased in patients with CAD in all three monocyte subsets. In both study groups, the majority of CCR5(+) cells was detected in CD14(++)CD16(+) monocytes (P<0.001 versus CD14(++)CD16(-) and CD14(+)CD16(++)), although the CCR5(+) monocyte number was reduced in patients with CAD (CD14(++)CD16(-)/CD14(+)CD16(++), P<0.001; CD14(++)CD16(+), P<0.05) compared with the HBD group, particularly in those who were not taking statins. Ex vivo incubation of monocytes from HBDs with plasma from patients with CAD also decreased CCR5(+) expression (P<0.05 versus plasma from HBDs). Serum CCL5 levels were similar in both groups. ConclusionsThe increased monocyte-platelet cross-talk in patients with CAD might have contributed to atherosclerosis progression. The decreased CCR5(+) monocyte numbers in patients with CAD could have resulted from CCR5(+) cell recruitment into atherosclerotic lesions or CCR5 downregulation in response to circulating factors."],["dc.identifier.doi","10.1111/joim.12145"],["dc.identifier.gro","3142194"],["dc.identifier.isi","000329764500006"],["dc.identifier.pmid","24118494"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/5577"],["dc.language.iso","en"],["dc.notes.intern","WoS Import 2017-03-10 / Funder: University Medical Center Gottingen"],["dc.notes.status","final"],["dc.notes.submitter","PUB_WoS_Import"],["dc.relation.eissn","1365-2796"],["dc.relation.issn","0954-6820"],["dc.title","Increased proatherogenic monocyte-platelet cross-talk in monocyte subpopulations of patients with stable coronary artery disease"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original"],["dspace.entity.type","Publication"]]

We aimed to address this gab by performing an external validation of the easy \"CTEPH rule-out-criteria\" based on a normal NT-proBNP level and the absence of 3 ECG characteristics. Methods: 134 patients underwent clinical follow-up 6 months after PE. Predefined transthoracic echocardiographic (TTE) criteria were used to categorize patients as \"PH unlikely\" or \"PH possible/likely\". The latter patients underwent further (invasive) diagnostic procedures to confirm and classify the diagnosis of pulmonary hypertension. NT-proBNP and ECGs, both assessed at the day of echocardiography, were evaluated post-hoc. Results: Sixty-three patients (47%) scored none of the \"CTEPH rule-out criteria\" positive, of whom 61 had normal TTE (97%). Twenty-five patients (19%) were categorized by TTE as \"PH possible/likely\"; of those, 6 were diagnosed with CTEPH. The sensitivity of rule-out criteria for CTEPH was 100% (95%CI 56-100%; 6/6 patients identified), and for \"PH possible/likely\" on TTE 92% (95%CI 74-99%; 23/25 patients identified): 2 asymptomatic patients with estimated systolic pulmonary arterial pressure of 36 mmHg and 38 mmHg, respectively, who remained stable during further 2-year follow-up, were not identified. Inter-observer agreement for the adjudication of the ECG characteristics was excellent (kappa-statistic 0.97). Conclusions: In this external validation cohort, we confirmed the diagnostic accuracy and reproducibility of the \"CTEPH rule-out criteria\". These results provide a solid ground for future outcome trials applying this algorithm.

In ferric chloride-induced carotid artery lesions in chow-fed mice, uPA deficiency increased neointimal size (P=0.015) and luminal stenosis (P=0.014), while reducing media thickness (P=0.002). A lack of uPA also increased the size of and the luminal obstruction from atherosclerotic plaques at the coronary and brachiocephalic arteries of apoE(-/-) mice. Plaques were characterised by a higher fibrinogen/fibrin content and a decrease in cellularity and collagen content. When apoE(-/-) and DKO mice were analysed as a single group, a significant-correlation was found between the (x-actin (smooth muscle cell) and collagen content of atherosclerotic lesions (r = 0.554; P < 0.05), and a negative correlation existed between the a-actin and fibrin/fibrinogen immunopositive area (r = -0.79 1; P < 0.001).

We therefore investigated the relationship between leptin levels and clinical outcome in patients with acute pulmonary embolism (PE). DESIGN: We prospectively studied consecutive patients with confirmed acute PE admitted at the University Hospital of Goettingen (Germany) between 2003 and 2009. SUBJECTS: The study subjects were a total of 264 patients with PE (median age, 68 years; interquartile range, 53-75; 60% women; body mass index (BMI) 27 kgm(-2) (24.1-31.2)). Leptin levels were determined by a commercially available enzyme-linked immunosorbent assay. Patients were followed for an adverse 30-day outcome, that is, death, circulatory collapse with need for catecholamines, intubation or resuscitation, and for long-term survival. RESULTS: The median leptin level was 10.1 ng ml(-1) (3.7-25.2). Patients (n = 49; 18.6%) with a complicated 30-day course had significantly lower leptin levels (5.3 ng ml(-1) (1.8-19.7) compared with patients without complications (10.4 ng ml(-1) (4.7-25.5), P = 0.02). When leptin was analyzed as a continuous variable, there was a significant 36% increase in the relative risk for early complications for every decrease in the natural logarithm of leptin by one s.d. (odds ratio (OR) 1.36 (1.06-1.76), P = 0.017), independently of BMI (BMI-adjusted OR, 1.52 (1.13-2.05), P = 0.006). In addition, patients within the lowest leptin tertile had a 2.8- and 2.3-fold increased risk for 30-day-complications, compared with those in the middle (P = 0.011) and high tertile (P = 0.030), and a worse probability of long-term survival (log-rank; P = 0.018). CONCLUSION: Low plasma leptin concentration is a predictor for a complicated course and high mortality in patients with acute PE. This association is independent of known factors affecting leptin levels, including gender and obesity.

In patients with acutemyocardial infarction, H-FABP plasma concentrations rise after 30 minutes and return to normal within 20-24 hours. We tested whether the predictive value of H-FABP is affected by the duration of symptoms prior to diagnosis in patients with PE. Material and Methods: We prospectively studied 257 consecutive normotensive patients with confirmed symptomatic PE. Results: Patients with acute (<24 hours; n = 150) symptom onset presented more often with syncope (28.7% vs. 6.5%; p < 0.001) compared to patients with symptoms >= 24 hours (n = 107); other baseline characteristics, comorbidities, and risk factors were distributed equally. Patients with an adverse 30-day outcome (6.6%) had higher H-FABP levels (11.84 [3.57-19.62] ng/ml) compared to patients with a favorable course (3.42 [1.92-5.42] ng/ml; p < 0.001). However, the proportion of patients with H-FABP levels >= 6 ng/ml did not differ among patients with acute symptom onset and late presentation (p = 0.104). Only tachycardia and elevation of H-FABP were associated with an increased risk of an adverse 30-day outcome both in patients with acute symptom onset (H-FABP: OR, 5.8; 95% CI, 1.4-24.5; p = 0.016; tachycardia: 7.0 [1.4-36.0]; p = 0.018) and late presentation (H-FABP: 9.3 [2.0-43.2]; p = 0.004 and tachycardia: 12.3 [1.5-103.6]; p = 0.021). The prognostic value could further be improved by the use of a simple H-FABP-based clinical prediction score.

However, the pathways and mediators lying downstream of leptin binding to platelets remain, with few exceptions, unknown. In the present study, we sought to gain further insight into the possible role of leptin as a platelet agonist. Stimulation of platelets with leptin promoted thromboxane generation and activation of alpha(IIb)beta(3), as demonstrated by PAC-I binding. Furthermore, it increased the adhesion to immobilised fibrinogen (p < 0.001) and induced cytoskeletal rearrangement of both platelets and Meg01 cells. Leptin time- and dose-dependently phosphorylated the intracellular signalling molecules JAK2 and STAT3, although the importance of STAT3 for leptin-induced platelet activation remains to be determined. Important intracellular mediators and pathways activated by leptin downstream of JAK2 were found to include phosphaticlylinositol-3 kinase, phospholipase C gamma 2 and protein kinase C,as well as the p38 MAP kinase-phospholipase A(2) axis. Accordingly, incubation with the specific inhibitors AG490, Ly294002, U73122, and SB203580 prevented leptin-mediated platelet activation.
