Abstract
BACKGROUND Caveolae are a prominent microdomain in endothelial cells and appropriate localization in caveolae is fundamental for endothelial nitric oxide synthase (eNOS) activity. Since the Glu298Asp variant in the eNOS gene alters caveolar localization of the corresponding enzyme, we tested the interaction between this variant and the rs4730751 polymorphism of the caveolin-1 (CAV-1) gene as related to arterial remodeling in end-stage renal disease (ESRD) patients. METHODS One hundred and thirty-three ethnically homogeneous ESRD patients underwent carotid ultrasonographic studies to measure intima-media thickness (IMT) and carotid cross-sectional area (CSA). Genotyping was performed by high-throughput allelic discrimination assays on real-time PCR. RESULTS Arterial remodeling was associated to the number of G alleles of CAV-1 polymorphism, GG homozygotes displaying an IMT and a CSA that were, respectively, 16% and 21% higher than those in patients without the risk allele (P < 0.012). In multiple linear regression analyses including the CAV-1 and the eNOS polymorphisms and adjusting for classical risk factors and risk factors peculiar to ESRD both polymorphisms were independent correlates of IMT (CAV-1: β = 0.20, P = 0.01; eNOS β = 0.25, P = 0.001) and CSA (CAV-1: β = 0.20, P = 0.01: eNOS β = 0.13, P = 0.09). Furthermore, strong interactions emerged between the two polymorphisms for explaining the variability in IMT (P = 0.001) and in CSA (P = 0.038) in these patients. CONCLUSION Overall these findings form preliminary evidence that disturbed interaction between CAV-1 and eNOS may be of relevance for arterial disease in ESRD and perhaps in other human diseases.

Abstract
BACKGROUND We investigated the relationship between fibrinogen and echocardiographic measurements of left ventricular (LV) geometry and LV function in a group of 192 patients with end stage renal disease (ESRD). RESULTS Patients in the third fibrinogen tertile had higher mean wall thickness (MWT), relative wall thickness (RWT) and left ventricular mass index (LVMI) and lower LV end diastolic diameter and LV ejection fraction than those in the other tertiles. On multivariate analysis fibrinogen resulted to be an independent correlate of MWT (P = 0.001) and RWT (P = 0.0001) and the first factor in rank explaining the variance in LV ejection fraction (P = 0.0001). Left ventricular concentric hypertrophy was more prevalent (P = 0.001) in patients in the third fibrinogen tertile (n = 35, 54%) than in those in the second (n = 24, 37%) and first (n = 13, 21%) tertiles. In a multiple logistic regression model patients in the third tertile of fibrinogen had a risk for left ventricular concentric hypertrophy that was 3.56 (95% CI: 1.56-8.14) fold higher than in those in the first tertile (P = 0.003). CONCLUSIONS Elevated fibrinogen is independently associated with LV concentric hypertrophy and systolic dysfunction in ESRD patients. These relationships may contribute to the negative prognostic impact of elevated fibrinogen levels in ESRD.

Abstract
BACKGROUND Whether hypertension and left ventricular hypertrophy (LVH) are more prevalent in CAPD than in haemodialysis (HD) patients is still under discussion. METHODS To examine this problem we compared a group of 51 CAPD patients, with a group of 201 HD patients. The evaluation included the measurement of atrial natriuretic peptide (atrial natriuretic factor (ANF)), taken as indicator of volume status, and echocardiographic measurements. RESULTS CAPD patients were older, had been treated for a shorter time, and had lower serum albumin and phosphate than HD patients. Plasma ANF was higher (P<0.01) in CAPD (median 33.8 pmol/l (interquartile range 18.2-63.0)) than in HD patients (22.7 pmol/l (14.9-38.7)). Similarly, the left atrial volume was substantially higher (P<0.0001) in CAPD patients (49+/-22 ml) than in HD patients (37+/-17 ml), while the left ventricular end-diastolic diameter was similar in the two groups (CAPD 51+/-7 mm; HD 50+/-7 mm). Furthermore, left ventricular hypertrophy was more severe (P<0.0001) in CAPD (157+/-37 g/m(2)) than in HD patients (133+/-39 g/m(2)). The proportion of CAPD patients requiring antihypertensive drugs was markedly higher than that of HD patients (65 vs 38% P<0.001). Multivariate modelling showed that volume expansion and pressure load as well as serum albumin were independent predictors of left ventricular mass. CONCLUSIONS Left ventricular hypertrophy is more severe in long-term CAPD patients than in HD patients. This finding is associated with evidence of more pronounced volume expansion, hypertension, and hypoalbuminaemia. Volume and pressure load along with factors associated with hypoalbuminaemia may aggravate LVH in uraemic patients on CAPD.

Abstract
OBJECTIVE To assess the relationship between advanced glycation end products (AGE) and cardiovascular damage in end-stage renal diseases. METHODS Ninety-one hemodialysis patients who had been on dialysis treatment for at least six months were recruited for the study. Each patient underwent echocardiography and an echo-color Doppler study of the carotid arteries. We measured plasma pentosidine and related it to intima media thickness, atherosclerotic plaques and parameters of left ventricular geometry. RESULTS Pentosidine was higher in patients treated by low-flux dialysis (31.0+/-16.6 pmol/mg protein) than in those treated by high-flux dialysis (25.4+/-7.6 pmol/mg protein), but this difference was of marginal statistical significance (P=0.08). On multivariate analysis, plasma IgG (beta=0.24, P=0.02) was the only independent correlate of plasma pentosidine. Intima media thickness and the number of atherosclerotic plaques were unrelated to plasma pentosidine. Mean wall thickness (beta=0.18, P<0.05), relative wall thickness (beta=0.20, P<0.05) and left ventricular end-diastolic volume (beta= -0.23, P<0.01) were independently related to plasma pentosidine. CONCLUSIONS Pentosidine, a reliable marker of "carbonyl stress", is unrelated to intima media thickness and to the number of atherosclerotic plaques, but it is related to alterations in heart geometry. These data suggest that the effect of carbonyl stress on the cardiovascular system is complex and that the effects of AGE on the heart may be dissociated from those on the arterial system.

Abstract
BACKGROUND In the general population, the plasma concentrations of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) are useful to predict left ventricular hypertrophy (LVH) and LV systolic dysfunction. Whether these cardiac hormones have a similar diagnostic potential in dialysis patients is unknown. METHODS We studied the diagnostic value of ANP and BNP for alterations in LV mass and function in a cohort of 246 dialysis patients without clinical evidence of heart failure. RESULTS Both ANP and BNP were independently related to left ventricular mass (P < 0.0001) as well as to ejection fraction (P < 0.0001). In an analysis based on a prospectively defined threshold (95th percentile of the normal range), BNP had a significantly higher (P < 0.01) sensitivity (88%) than ANP (51%) for the diagnosis of LVH, but the positive predictive value of the two peptides was very similar (92 and 87%, respectively, P = NS). However, the negative predictive value of BNP for excluding LVH was 22% higher than that of ANP (53 vs. 31%, P = 0.05). Both natriuretic peptides had a high sensitivity for the detection of LV dysfunction (87 and 94%), but their positive predictive value was low (25 and 15%). Importantly, both ANP and BNP proved to be very useful for excluding this alteration (negative predictive value 97 and 96%, respectively). An analysis based on the "best cut-offs" of each peptide as identified on the basis of the ROC curves augmented the positive and negative prediction values of BNP for the diagnosis of LVH to 95 and 61%, respectively. This approach also raised the BNP-positive prediction value for the identification of LV dysfunction to 31% but did not modify the diagnostic potential of ANP (either for LVH or for LV dysfunction). CONCLUSIONS Measuring the plasma concentration of cardiac natriuretic hormones, particularly BNP, may be useful for the identification of dialysis patients with LVH or for excluding systolic dysfunction.

Abstract
OBJECTIVE Nocturnal hypoxemia has recently been proposed as a cardiovascular risk factor in patients with chronic renal failure. In this study we have tested the hypothesis that this disturbance is associated with left ventricular hypertrophy (LVH) in dialysis patients. METHODS During a mid-week non-dialysis day, 38 hemodialysis patients underwent continuous monitoring of arterial O2 saturation (SaO2) during night-time as well as 24 h ambulatory blood pressure monitoring and echocardiography. RESULTS Eighteen patients had one or more episodes of O2 desaturation during night-time (average: 21 episodes; range 1 to 120) while the other 20 had no episode. Neither day-time arterial pressure nor heart rate were significantly associated with nocturnal hypoxemia. However there was a significant correlation between the night/day systolic ratio and the severity of hypoxemia during night-time (r = 0.36, P = 0.03). On multivariate analysis, nocturnal hypoxemia proved to be the stronger independent predictor of relative wall thickness, mean wall thickness and left ventricular mass index, suggesting that nocturnal O2 desaturation is linked to concentric hypertrophy and to concentric geometry of the left ventricle. Accordingly, the proportion of patients with such geometric alteration was higher (chi2 = 4.1, P = 0.04) in patients with a pulse oximetry severity score > 50th percentile [15 of 19 (79%)] than in those below this threshold [nine of 19 (47%)]. CONCLUSIONS Nocturnal hypoxemia is an important correlate of LVH in hemodialysis patients. Such an association is largely independent of arterial pressure. These data further underscore the importance of disturbed respiratory control as a cardiovascular risk factor in dialysis patients.

Abstract
BACKGROUND Autonomic dysfunction and sleep apnoea are frequent complications of chronic renal failure. Since nocturnal hypoxaemia in sleep apnoea dampens autonomic reflexes, we postulated that altered autonomic control is in part linked to nocturnal hypoxaemia in uraemic patients. METHODS To test the hypothesis we performed continuous monitoring of O(2) saturation during night by pulse oximetry (Ohmeda-Biox) as well as echocardiography, 24-h ambulatory blood pressure monitoring, and standard tests of autonomic function in 50 patients on chronic dialysis (40 on haemodialysis and 10 on CAPD). For haemodialysis patients all studies were performed during a mid-week non-dialysis day. RESULTS Twenty-five patients had at least one episode of nocturnal hypoxaemia (median 13, interquartile range 4-31) while the other 25 patients had no episodes at all. Minimal and average SaO(2) were strongly interrelated (r = 0.64, P = 0.0001). In a multiple regression model, besides age, average nocturnal SaO(2) was the only independent predictor of the parasympathetic function. Similarly, average nocturnal SaO(2) was the only independent predictor of the autonomic response to standing. Sex, 24-h mean arterial pressure, body mass index, haematocrit, serum albumin, serum parathyroid hormone and duration of dialysis treatment had no independent effect on the autonomic tests. Interestingly, the average nocturnal SaO(2) and the interaction between the responses to the autonomic tests were independently related to posterior-wall thickness. This interaction term represented also the stronger independent predictor of the relative wall thickness of the left ventricle. In a multiple logistic regression model the interaction parasympathetic-sympathetic function was the only independent predictor of concentric remodelling or hypertrophy, while average nocturnal SaO(2) entered into this model (P = 0.03) only after exclusion of the autonomic function interaction term. CONCLUSIONS Thus, altered cardiovascular autonomic control appears to be linked to nocturnal hypoxaemia and to concentric hypertrophy or remodelling in dialysis patients. Since nocturnal hypoxaemia is an established cardiovascular risk factor, altered autonomic control is a potential mechanism whereby hypoxaemia may trigger cardiovascular events in dialysis patients. It remains to be seen whether the link between nocturnal hypoxaemia and autonomic dysfunction is a causal one.

Abstract
Hepatocyte growth factor (HGF) is a pleiotropic cytokine involved in tissue protection and repair in the endothelium and various organ systems. The serum concentration of this protein is markedly increased in patients with chronic renal diseases, but the clinical and pathophysiological correlates of this substance in renal failure are scarcely understood. Serum HGF, lipid, albumin, hemoglobin, C-reactive protein (CRP), and immunoglobulin G (IgG) were measured in fasting conditions in a cohort of 244 dialysis patients. In addition, the relationship between HGF and severity of carotid atherosclerosis was studied in a subgroup of 105 patients. The entire cohort was followed up for a median of 31 months (interquartile range, 21 to 34 months). Serum HGF level was directly related to duration of dialysis treatment, CRP level, age, IgG level, and hemoglobin level and inversely related to systolic and diastolic arterial blood pressure. In a multiple regression model, only duration of dialysis treatment (r = 0.38), age (r = 0.26), hemoglobin level (r = 0.17), IgG level (r = 0.15), and CRP level (r = 0.14) were independent correlates of serum HGF level (R = 0.54; P < 0.0001), suggesting that increased levels of serum HGF may be the expression of a chronic inflammatory process. HGF levels were greater in hemodialysis than continuous ambulatory peritoneal dialysis patients, independent of the type of dialysis membrane, and slightly increased in patients seropositive for hepatitis C virus. In the subgroup of patients who underwent echo color Doppler studies, serum HGF level was an independent correlate of intima media thickness (IMT; partial r = 0.23; P = 0.02). In the entire cohort, increased HGF levels predicted shorter survival in a multivariate Cox regression model. These results support the hypothesis that in patients with chronic renal failure, increased serum HGF level is linked to an inflammatory state. The relationships between HGF level and survival and IMT suggest that this cytokine might be a marker of a process that has a major impact in the high mortality and morbidity of the dialysis population.

Abstract
OBJECTIVE To investigate the relationship between inflammatory processes and atherosclerosis in uraemic patients on chronic dialysis. DESIGN A cross-sectional study in 138 dialysis patients (92 on haemodialysis and 46 on continuous ambulatory peritoneal dialysis). METHODS Serum C-reactive protein (CRP), IgG anti-Chlamydia pneumoniae antibodies, lipoprotein (a), fibrinogen and plasma homocysteine as well as the intima-media thickness and the number of atherosclerotic plaques of the carotid arteries (by Echo-Colour-Doppler) were measured in each patient RESULTS One hundred and eight patients had at least one plaque and 26 had more than six plaques. Serum CRP was above the upper limit of the normal range (5 mg/I) in 85 of 138 patients (62%). IgG anti-Chlamydia pneumoniae antibodies were detectable in 64% of patients (high level in 24%, intermediate in 33% and low in 7%) and undetectable in the remaining 36% of patients. In a multiple regression model age (beta=0.35), serum CRP (beta=0.23), plasma homocysteine (beta=0.19), duration of dialysis (beta=0.19) and pulse pressure (beta=0.18) were independent predictors of intima-media thickness (R=0.54, P < 0.0001). Similarly, age (beta=0.33), serum CRP (beta=0.29), plasma homocysteine (beta=0.20) and serum albumin (beta=-0.18) were independent correlates of the number of atherosclerotic plaques (R = 0.55, P < 0.0001 ). Furthermore, in smokers, the interaction serum CRP-IgG anti-Chlamydia pneumoniae antibodies was the stronger independent predictor (beta=0.43, P=0.0001) of the number of atherosclerotic plaques while no such relationship (P=0.73) was found in non-smokers. CONCLUSIONS In patients on chronic dialysis treatment CRP is independently associated to carotid atherosclerosis and appears at least in part to be explained by IgG anti-Chlamydia pneumoniae antibodies level. These data lend support to the hypothesis that inflammation plays a role in the pathogenesis of atherosclerosis in these patients.

Abstract
OBJECTIVE Arterial hypertension is an established risk factor for left ventricular hypertrophy (LVH) in the uremic population. However, whether 24-h monitoring is a better predictor of LVH than clinic blood pressure and routine pre-dialysis measurements in these patients is still undefined. METHODS This problem was studied in 64 nondiabetic hemodialysis patients without heart failure. The echocardiographic study as well as the clinic and 24-h ambulatory blood pressure (BP) measurements were performed during the day off-dialysis. Pre-dialysis arterial pressure was calculated as the average value of the 12 routine recordings taken during the month preceding the study. RESULTS In multivariate models, including also sex, body mass index, hematocrit and serum cholesterol, pre-dialysis systolic, diastolic and pulse pressures were the only independent BP determinants of heart geometry. Twenty-four hour ambulatory BP monitoring (ABPM) did add significant (but weak) information to the prediction of left ventricular internal dimension, i.e. it increased by 9% (P = 0.01) the variance already explained by pre-dialysis diastolic BP and other significant covariates. However, 24-h ABPM did not add any significant and independent explanatory information to the corresponding pre-dialysis measurements for the posterior wall and interventricular septum measurements, and for left ventricular mass (-0.6 to +3.9%; average +1.1%). CONCLUSIONS In dialysis patients, pre-dialysis BP is at least as strong a predictor of left ventricular mass as 24-h ambulatory monitoring. Thus, the average of 12 routine pre-dialysis measurements may be used to predict heart geometry in dialysis patients without any loss of information in comparison with 24-h ambulatory monitoring.

Abstract
AIM To investigate the relationship between carotid atherosclerosis and some major cardiovascular risk factors in uremic patients on chronic dialysis. METHODS A cross-sectional study was carried out in 119 unselected dialysis patients (89 on hemodialysis and 30 on chronic ambulatory peritoneal dialysis, CAPD). Fasting blood sampling for serum lipids, albumin, hemoglobin, and echo-colour-Doppler evaluation of common carotid arteries were performed in all patients (during the non-dialysis day in hemodialysis patients). In hemodialysis patients BP was measured before and after dialysis; in CAPD patients home BP values were recorded during the month before the study day. RESULTS Ninety-five patients had at least one plaque and 57 had at least four plaques. Thirty-eight had mild and eleven severe carotid stenosis. In multiple regression models, the mean internal diameter of carotid arteries was explained (R=0.52, P=0.0001) by systolic pressure (r=0.39), serum cholesterol (r=-0.28), age (r=0.27) and smoking (r=0.24) while the degree of carotid stenosis was predicted (R=0.39, P=0.0001) by age (r=0.36) and smoking (r=0.25). The number of atherosclerotic plaques was explained (R=0.51, P=0.0001) by age (r=0.36), smoking (r=0.25) and pulse pressure (r=0.20), serum albumin just failing to reach statistical significance (P = 0.06). However, serum albumin was a significant and independent predictor of the number of atherosclerotic plaques (r=-0.26) in hemodialysis patients (n=89). Sex, diabetes, Kt/V, duration of dialysis treatment, hemoglobin, serum calcium and phosphate did not add any predictive power to the models. CONCLUSIONS In dialysis patients arterial pressure and smoking are associated with carotid atherosclerosis. Serum albumin appears to serve as an independent predictor of carotid atherosclerosis.

Abstract
It is well established that nocturnal hypoxemia in sleep apnea causes an inversion of the circadian arterial pressure rhythm and triggers nocturnal hypertension. Since sleep apnea is very frequent in dialysis patients, we hypothesized that nocturnal hypoxemia may be a factor that contributes to alter the 24-hour arterial pressure profile in these patients. To test the hypothesis 32 dialysis patients underwent 24-hour blood pressure (BP) monitoring and continuous monitoring of arterial O2 saturation during the night-time. Hemodialysis patients were studied during the non-dialysis day. All patients underwent an echocardiographic study. Thirteen patients had no episode of nocturnal hypoxemia (group I), 7 had at least one episode overnight but less than 2 episodes/hr (group II) and 12 had > or = 2 episodes/hr (group III). The average daytime systolic pressure was similar in the three groups. However, the average nocturnal systolic pressure fell in the first group (-2.5 +/- 4.2%) and rose in the second (+2.0 +/- 3.6%) and in the third (+3.9 +/- 2.2%) group (one way ANOVA, P < 0.005). The relative wall thickness of the left ventricle (RWT) was significantly (P < 0.05) higher in group III than in group I, and in the aggregate (N = 32) there was an inverse relationship between average nocturnal SaO2 and RWT (r = -0.43, P = 0.015). The proportion of patients with concentric remodeling or concentric hypertrophy was higher (P = 0.05) in the group with a more severe degree of nocturnal hypoxemia (group III, 8 of 12) than in the other two groups (group I, 3 of 13; group II, 2 of 7). Nocturnal hypoxemia is associated with the "non-dipping" arterial pressure profile in dialysis patients. Disturbed respiratory control during the night may represent an important cardiovascular risk factor in dialysis patients.

Abstract
The aim of the study was to investigate the release of endothelin-1 (ET-1) in normal and varicose saphenous veins at baseline and after venous stasis test. Ten patients (eight women and two men, mean age 43 +/- 4) with primarily varicose great saphenous veins and ten controls (eight women and two men, mean age 42 +/- 6) were recruited. After 30 minutes of resting in supine position, venous occlusion in a leg was performed with a sphygmomanometer provided to keep the pressure in the cuff intermediate between systolic and diastolic blood pressure for 10 minutes. Blood samples were taken from the great saphenous vein just above the medial malleolus at baseline and 10 minutes after venous stasis was begun. Plasma ET-1 was determined by a radioimmunoassay system. Results are expressed as mean +/- SD. Plasma ET-1 concentration was higher in varicose than in normal saphenous veins (4 +/- 0.1 pmol/L vs 2.6 +/- 0.1 pmol/L, P < 0.001), and it significantly increased (P < 0.001) in both groups after venous stasis when compared with baseline (6.8 +/- 0.9 pmol/L and 3.6 +/- 0.1 pmol/L in varicose and normal saphenous veins, respectively). Absolute increase in plasma ET-1 was significantly greater in varicose than in normal saphenous veins (2.8 +/- 0.9 pmol/L vs 1.0 +/- 0.2 pmol/L, P < 0.01). In conclusion, increased local ET-1 release in varicose saphenous veins could be a marker for venous endothelial activation/damage and/or contribute to promote the morphologic alterations of the varicose vein wall by stimulating smooth muscle cell proliferation. On the other hand, increased ET-1 release could contribute to counterbalancing the varicose venous relaxation and to increasing preload in varicose patients via ET-1-induced venoconstriction.

Abstract
Popliteal cysts presenting as thrombophlebitis are unusual diseases of the popliteal fossa and are commonly associated with rheumatoid arthritis or meniscal tears. The authors report the case of a 38-year-old man with Reiter's syndrome in which a synovial cyst of the popliteal space, mimicking symptoms suggestive of deep venous thrombosis, complicated the course of the arthritis. Clinical and diagnostic features of this rare popliteal pathology are discussed and the usefulness of noninvasive diagnostic methods for detecting this disease, in particular that of echotomography, is emphasized. The authors stress the importance of a correct diagnosis in order to avoid the risks of an erroneous anticoagulant treatment.
