Selected AbstractsRheological determinants of red blood cell aggregation in diabetic patients in relation to their metabolic controlDIABETIC MEDICINE, Issue 2 2002K. Elishkevitz Abstract Aims To determine whether increased red blood cell adhesiveness/aggregation in diabetic patients is related to the extent of their metabolic control. Methods We measured erythrocyte adhesiveness/aggregation in a group of 85 adult patients with diabetes mellitus by using citrated venous whole blood and a simple slide test. The erythrocyte adhesiveness/aggregation was determined by measuring the size of the spaces that are formed between the aggregated erythrocytes. We divided the patients into those with either low or high erythrocyte adhesiveness/aggregation values. Results The erythrocyte adhesiveness/aggregation values of the two groups differed significantly in terms of their fibrinogen concentration, erythrocyte sedimentation rate, high sensitive C-reactive protein (CRP), total cholesterol and triglyceride concentrations. There was no difference between the two groups regarding the concentrations of HbA1c. Logistic regression was applied to construct a model to predict the belonging of a patient in the low or high erythrocyte adhesiveness/aggregation group. A linear regression was applied to construct a model to predict the erythrocyte adhesiveness/aggregation values. Both models turned out to include gender, age, fibrinogen, triglyceride, retinopathy, coronary artery disease and age and gender interaction. Neither HbA1c nor CRP entered the models. Conclusions The degree of erythrocyte adhesiveness/aggregation and several variables of the acute-phase response in patients with diabetes mellitus are not directly related to the degree of metabolic control as evaluated by means of HbA1c concentration. Diabetic patients might benefit from rheological or anti-inflammatory interventions regardless of their metabolic control. [source] Increased plasma fibrin gel porosity in patients with Type I diabetes during continuous subcutaneous insulin infusionJOURNAL OF THROMBOSIS AND HAEMOSTASIS, Issue 6 2003G. Jörneskog Summary.,Background:,Patients with Type 1 diabetes have a tighter plasma fibrin gel structure, to which impaired glycemic control might contribute. Improved glycemic control can be achieved with continuous subcutaneous insulin infusion (CSII). Objectives:,The aim of the present study was to investigate the effect of CSII on plasma fibrin gel properties and circulating markers of inflammatory activity in patients with Type 1 diabetes. Patients and methods:,Twenty-eight patients were investigated before and after 4,6 months' treatment with CSII. Fibrin gel structure formed in vitro from plasma samples was investigated by liquid permeation of hydrated fibrin gel networks. P-fibrinogen was analyzed by a syneresis method. Comparisons were made between patients with improved (> 0.5%) and unchanged (< 0.5%) glucosylated hemoglobin (HbA1c) during CSII. Results:,Eighteen patients showed improved and 10 patients unchanged HbA1c during CSII. P-fibrinogen, high sensitive C-reactive protein and serum amyloid A-antigen were not significantly changed, while fibrin gel permeability (Ks) and fiber mass,length ratio (µ) increased in both groups (P < 0.02). P-insulin and triglycerides decreased (P < 0.05) in both groups, while reductions of total cholesterol and intercellular adhesion molecule-1 were seen only in patients with improved HbA1c (P < 0.05). Absolute changes in Ks were inversely correlated to changes in plasma fibrinogen (r = 0.50; P < 0.01) and in LDL-cholesterol (r = 0.46; P < 0.05). Conclusions:,Treatment with CSII in patients with Type 1 diabetes is associated with increased plasma fibrin gel porosity. Slight attenuation of the inflammatory activity was also observed. The changes in fibrin gel porosity seem to be mainly mediated by changes in plasma fibrinogen and blood lipids, and are probably secondary to improved insulin sensitivity. [source] Short-term effects of periodontal therapy as an adjunct to anti-lipemic treatmentORAL DISEASES, Issue 7 2010Ö Fento Oral Diseases (2010) 16, 648,654 Objective:, This study was conducted to assess the effect of improved periodontal health following periodontal treatment on metabolic lipid control of patients on anti-lipemic treatment. Materials and Methods:, The study population consisted of 20 patients aged 34,62 years with diagnoses of hyperlipidemia and chronic periodontitis. All patients used statin to treat their elevated levels of low-density lipoprotein cholesterol. Blood samples were obtained for measurement of serum lipids, fasting plasma glucose, and high sensitive C-reactive protein. Periodontal parameters, including plaque index, gingival index, probing pocket depth, clinical attachment level, and percentage of bleeding on probing, were evaluated. All parameters were assessed in each subject at baseline, after 3 months as a control (at the time of periodontal treatment), and 3 months after the non-surgical periodontal treatment that included scaling and root planning. Results:, All lipid parameters decreased after the periodontal treatment, but only the decreases in total cholesterol and low-density lipoprotein cholesterol levels reached statistical significance compared to baseline (P = 0.002 and P = 0.003, respectively). Conclusion:, Improved periodontal health may influence metabolic control of hyperlipidemia and could be considered as an adjunct to the standard measures of hyperlipidemic patient care. [source] ORIGINAL RESEARCH,ERECTILE DYSFUNCTION: Independent Determinants of Coronary Artery Disease in Erectile Dysfunction PatientsTHE JOURNAL OF SEXUAL MEDICINE, Issue 4pt1 2010Shih-Tai Chang MD ABSTRACT Introduction., There is growing evidence of a link between erectile dysfunction (ED) and coronary artery disease (CAD). Aims., The purpose of this study was to explore the independent determinants of CAD in ED outpatients. Methods., This study enrolled 243 patients, ranging in age from 21 to 81 years old, suffering from ED as diagnosed by the International Index of Erectile Function (IIEF) scores. All patients underwent exercise stress tests or thallium-201 single-photon emission computed tomography perfusion imagings. Based on examination results, patients were divided into study (22 patients with a positive finding) and control groups (221 patients with a negative finding). Main Outcome Measures., The differences of demographic characteristics, biochemical profiles, pro-inflammatory and inflammatory markers, and echocardiographic characteristics between study and control group were compared. Results., The age, presence of DM and current smoking status were significant high in the study group. A significant lower high-density lipoprotein (HDL) cholesterol level, a higher percentage of HDL cholesterol level < 40 mg/dL, and a higher apo-lipoprotein B/A1, high sensitive C-reactive protein (hs-CRP) and homocysteine found in the study group. The Framingham cardiac risk scores, the ratio of mitral inflow velocity to early diastolic velocity in the annulus derived by tissue Doppler imaging (E/Et), the ratio of E/Et , 15, the value of carotid intima-media thickness (IMT), and IMT , 1 mm were higher in study group than in the control group. In stepwise multiple logistic regression analysis, a high waist-to-hip ratio (WHR), high IMT, high E/Et, hs-CRP levels, LDL cholesterol , 130 mg/dL, smoking status, and the presence of DM and metabolic syndrome (MS) were independent determinants of CAD in ED patients. Conclusions., This study first shows the independent determinants of CAD in ED outpatients. This novel finding may improve the screening of low-risk ED patients for CAD.

[source] The effects of thyroxine replacement on the levels of serum asymmetric dimethylarginine (ADMA) and other biochemical cardiovascular risk markers in patients with subclinical hypothyroidismCLINICAL ENDOCRINOLOGY, Issue 2 2005Omer Ozcan Summary Background, The relationship between subclinical hypothyroidism (SH) and cardiovascular disease (CVD) is still under debate. The purpose of the present study was to evaluate plasma total homocysteine (tHcy), high sensitive C-reactive protein (hsCRP), small dense low-density lipoprotein (sdLDL), l -arginine and asymmetric dimethylarginine (ADMA) concentrations and their relationship to nitric oxide (NO) production, measured as plasma nitrite-plus-nitrate (NOx) concentration, in patients with SH before and after thyroxine replacement therapy and compared with control group values. Design, Eighty-four women with SH and 33 healthy women as controls matched to the patient group for sex, age and body mass index (BMI), were enrolled in this study. Lipoprotein profile, tHcy, hsCRP, sdLDL, ADMA, l -arginine and NOx were measured in pre- and post-treatment blood samples. Results, The pretreatment total cholesterol (TC), LDL-C, hsCRP, ADMA and l -arginine levels were significantly higher and NOx levels were lower than in the control group. After treatment, hsCRP, ADMA and l -arginine levels were significantly reduced and sdLDL and NOx levels were significantly increased. Conclusion, The present study demonstrated an elevation of hsCRP and ADMA plasma levels of patients with SH associated with a reduction in NO production, which may contribute to some cardiovascular alterations. The elevated ADMA and hsCRP levels were reduced after thyroxine replacement. Also the sdLDL levels of SH patients were found to be lower than the control group values whereas TC and LDL were elevated. Even though we found an elevation in sdLDL levels after treatment, those values were still not higher than in the control group. [source] Nitric Oxide Metabolites Are Associated with Survival in Older PatientsJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 9 2007Toshio Hayashi MD OBJECTIVES: To assess the efficacy of various vascular endocrinological substances, such as plasma nitric oxide metabolites (NOx), as surrogate markers of survival in older patients. DESIGN: Prospective cohort, observational. SETTING: Nagoya University Hospital and related hospitals, Japan. PARTICIPANTS: One hundred fifty patients aged 70 and older, recruited consecutively from the outpatient clinics of Nagoya University Hospital and related hospitals. MEASUREMENT: Serum biochemical analyses such as albumin and total cholesterol, various prognostic markers, such as tumor necrosis factor (TNF)-,, NOx, activities of daily living (ADLs), and instrumental ADLs (IADLs) were evaluated on enrollment. ADLs, IADLs, and comorbidities, especially depression and impaired cognition, were evaluated on enrollment. The main outcome was survival rate over 2.75 years. RESULTS: Forty-nine patients died during the follow-up period. Mann-Whitney U -test showed that hemoglobin, total protein, serum albumin, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, high sensitive c-reactive protein, NOx, B-type natriuretic peptide, interleukin-6, and TNF-, levels; ADLs; cognitive impairment; and depressive status were significantly different for subjects who survived and those who died. Of the dependent variables in the Cox proportional hazards regression analyses, only ADLs, NOx, and albumin were significantly different. In the Kaplan-Meier analyses of mortality, the prognosis of patients in the third and fourth quartiles of NOx was significantly worse than that of patients in the first or second quartile. The prognosis of patients with impaired ADLs was worse than that of other patients for the overall period. CONCLUSION: Lower levels of NOx may be associated with survival in older patients. It may be an effective marker, like ADLs, which is a well-known marker. [source] | ||||||||||
