- Background and objective Obstructive sleep apnoea (OSA) and hyperlipidaemia are independent risk factors for cardiovascular disease. This study investigates the association between OSA and prevalence of hyperlipidaemia in patients of the European Sleep Apnea Database (ESADA) cohort. Methods The cross-sectional analysis included 11 892 patients (age 51.9 +/- 12.5 years, 70% male, body mass index (BMI) 31.3 +/- 6.6 kg/m(2), mean oxygen desaturation index (ODI) 23.7 +/- 25.5 events/h) investigated for OSA. The independent odds ratio (OR) for hyperlipidaemia in relation to measures of OSA (ODI, apnoea-hypopnoea index, mean and lowest oxygen saturation) was determined by means of general linear model analysis with adjustment for important confounders such as age, BMI, comorbidities and study site. Results Hyperlipidaemia prevalence increased from 15.1% in subjects without OSA to 26.1% in those with severe OSA, P < 0.001. Corresponding numbers in patients with diabetes were 8.5% and 41.5%, P < 0.001. Compared with ODI quartile I, patients in ODI quartiles II-IV had an adjusted OR (95% CI) of 1.33 (1.15-1.55), 1.37 (1.17-1.61) and 1.33 (1.12-1.58) (P < 0.001), respectively, for hyperlipidaemia. Obesity was defined as a significant risk factor for hyperlipidaemia. Subgroups of OSA patients with cardio-metabolic comorbidities demonstrated higher prevalence of HL. In addition, differences in hyperlipidaemia prevalence were reported in European geographical regions with the highest prevalence in Central Europe. Conclusion Obstructive sleep apnoea, in particular intermittent hypoxia, was independently associated with the prevalence of hyperlipidaemia diagnosis.

- Background and objective OSA and PLMS are known to induce acute BP swings during sleep. Our current study aimed to address the independent effect of PLMS on BP in an unselected OSA patient cohort. Methods This cross‐sectional analysis included 1487 patients (1110 males, no previous hypertension diagnosis or treatment, mean age: 52.5years, mean BMI: 30.5kg/m2) with significant OSA (defined as AHI≥10) recruited from the European Sleep Apnoea Cohort. Patients underwent overnight PSG. Patients were stratified into two groups: patients with significant PLMS (PLMSI>25 events/hour of sleep) and patients without significant PLMS (PLMSI<25 events/hour of sleep). SBP, DBP and PP were the variables of interest. For each of these, a multivariate regression linear model was fitted to evaluate the relationship between PLMS and outcome adjusting for sociodemographic and clinical covariates (gender, age, BMI, AHI, ESS, diabetes, smoking and sleep efficiency). Results The univariate analysis of SBP showed an increment of BP equal to 4.70mm Hg (P<0.001) in patients with significant PLMS compared to patients without significant PLMS. This increment remained significant after implementing a multivariate regression model (2.64mm Hg, P = 0.044). No significant increment of BP was observed for DBP and PP. Conclusion PLMS is associated with a rise in SBP regardless of AHI, independent of clinical and sociodemographic confounders. A PLMS phenotype may carry an increased risk for cardiovascular disease in OSA patients.

- The HMr and LMr molecular forms of kininogen were found to occur in normal distribution in plasma from a patient with severe haemophilia A. Present findings indicate that lack of Factor VIII does not influence, the normal content and distribution of immunoreactive kininogens determined by single radial immunodiffusion and radioimmunoassay. The partially purified HMr and LMr kininogens were antigenically identical with the kininogens in normal human plasma determined using the monospecific antisera raised in rabbits against purified kininogen antigens. Low kallikrein activity on H-D-Pro-Phe-Arg-pNA in the haemophilic plasma was apparently due to preparative procedures. This concept is supported by the normal binding ratio of trypsin to pure α2-macroglobulin isolated from the haemophilic plasma.

- Haemorrhages represent a major complication of treatment with vitamin K antagonists. In cases of severe bleeding, a prompt effect on the increased International Normalized Ratio value is vital to achieve haemostasis. As conventional treatment, that is plasma or plasma-derived concentrates, carries the risk of blood-borne virus transmission, new treatments are needed. An open, multicentre pilot trial is currently under way to determine the effect of recombinant activated factor VII (rFVIIa; NovoSeven) administered to patients experiencing a bleeding episode after receiving vitamin K antagonists. When rFVIIa was given to a patient with a warfarin-induced nosebleed, it had an immediate haemostatic effect and the International Normalized Ratio value virtually normalized.

- Obstructive sleep apnea (OSA) and asthma are often associated and several studies suggest a bidirectional relationship between asthma and OSA. This study analyzed the characteristics of patients with suspected OSA from the European Sleep Apnea Database according to presence/absence of physician-diagnosed asthma. Cross-sectional data in 16,236 patients (29.1% female) referred for suspected OSA were analyzed according to occurrence of physician-diagnosed asthma for anthropometrics, OSA severity and sleepiness. Sleep structure was assessed in patients studied by polysomnography (i.e. 48% of the sample). The prevalence of physician-diagnosed asthma in the entire cohort was 4.8% (7.9% in women, 3.7% in men, p < 0.0001), and decreased from subjects without OSA to patients with mild-moderate and severe OSA (p = 0.02). Obesity was highly prevalent in asthmatic women, whereas BMI distribution was similar in men with and without physician-diagnosed asthma. Distribution of OSA severity was similar in patients with and without physician-diagnosed asthma, and unaffected by treatment for asthma or gastroesophageal reflux. Asthma was associated with poor sleep quality and sleepiness. Physician-diagnosed asthma was less common in a sleep clinic population than expected from the results of studies in the general population. Obesity appears as the major factor raising suspicion of OSA in asthmatic women, whereas complaints of poor sleep quality were the likely reason for referral in asthmatic men.

- Background: Recent studies show that FVIIa binds to endothelial cell protein C receptor (EPCR) on vascular endothelium; however, the importance of this interaction in hemostasis or pathophysiology is unknown. Objective, The aim of the present study is to investigate the role of FVIIa interaction with EPCR on the endothelium in mediating FVIIa transport from the circulation to extravascular tissues. Methods: Wild-type, EPCR-deficient or ECPR-over expressing mice were injected with human rFVIIa (120 μg/kg b.w.) via tail vein. At varying time intervals following rFVIIa administration, blood and various tissues were collected to measure FVIIa antigen and activity levels. Tissue sections were analyzed by immunohistochemistry for FVIIa and EPCR. Results: The data reveal that, following intravenous injection, rFVIIa rapidly disappears from blood and associates with the endothelium in an EPCR-dependent manner. Immunohistochemical analyses revealed that association of FVIIa with the endothelium was maximal at 30 min and thereafter progressively declined. FVIIa association with the endothelium was undetectable at time points exceeding 24 h post FVIIa administration. The levels of rFVIIa accumulated in tissue correlates with expression levels of EPCR in mice and FVIIa associated with tissues remained functionally active for periods of at least 7 days. Conclusions: The observation that EPCR-dependent association of FVIIa with the endothelium is most pronounced soon after rFVIIa administration and subsequently declines temporally, combined with the retention of functionally-active FVIIa in tissue homogenates for extended periods, indicates that FVIIa binding to EPCR on the endothelium facilitates the transport of FVIIa from circulation to extravascular tissues where TF resides. © 2012 International Society on Thrombosis and Haemostasis.
