Abstract

BACKGROUND: Myocardial infarction is one of the coronary artery diseases caused by plaque rupture, plaque erosion or calcified nodules, with the occurence of thrombus formation and artery occlusion. YKL-40 has a functional role in plaque fibrous formation because of its high expression during fibrosis development, vascular smooth muscle cells differentiation, elevated matrix turnover and tissue remodelling in old myocardial infarction, whereas CD40 ligand, which is stored in the cytoplasm of resting platelets, rapidly presents on the surface. After cleavage, a soluble functional CD40 ligand (sCD4OL) is generated. The aim of this study was to assess the association between YKL-40 and sCD4OL in old myocardial infarction.METHODS: This study used the cross sectional study design. Fifty six patients with old myocardial infarction were selected based on their electrocardiographical results. Among these patients, 23 subjects had hypertension and 15 subjects had hsCRP >3-l0 mg/L. YKL-40 and sCD40L were measured by ELISA method.RESULTS: There was no significant correlation between YKL-40 and sCD40L (r=0.078; p=0.569) in old myocardial infarction and in subjects with hsCRP >3-10 mg/L (r=0.524; p=0.045). However, significant positive correlations Were found in subjects with hypertension (r=0.447; p=0.029).CONCLUSIONS: Our findings showed that YKL 40 correlated significantly with sCD4OL in subjects with hypertension.KEYWORDS: myocardial infarction, ruptured plaque, coronary artery disease, YKL-40, soluble CD40 ligand

Abstract

BACKGROUND: Mesenchymal stromal cells are multipotent cells considered to be of great promise for use in regenerative medicine. However, the cell dose may be a critical factor in many clinical conditions and the yield resulting from the ex vivo expansion of mesenchymal stromal cells derived from bone marrow may be insufficient. Thus, alternative sources of mesenchymal stromal cells need to be explored.CONTENT: There are multiple extra-embryonic tissues emerging during gestation including umbilical cord blood (UCB), amniotic fluid (AF), Wharton’s jelly, the amniotic membrane and the placenta, which are all discarded following birth. Fetal stem cells from these sources actually represent a new class of stem cells developmentally and operationally located between the state of embryonic stem cells and adult stem cells, sharing and exhibiting features of pluripotency and multipotency, without necessarily implying that they can generate every type of tissue.SUMMARY: Fetal stem cells have been recently isolated from several tissues (amniotic fluid, umbilical cord, Wharton’s jelly, amnion and placenta). They are derived either from the fetus proper or from the supportive extra-embryonic structures. They represent ideal sources for regenerative medicine since they are easily accessible, exhibit high proliferation rates, do not form teratomas and present no ethical reservations like embryonic stem cells (ESC). Their functional features indicate that they actually represent intermediates between ESC and adult stem cells.KEYWORDS: mesenchymal stem cells, fetal stem cells, amniotic fluid, umbilical cord, placenta, wharton’s jelly

Abstract

BACKGROUND: Central obesity is associated with various chronic metabolic disorders characterized by abnormal cytokine production, increased acute phase reactants, and activation of inflammatory signaling pathways. This study was aimed to investigate the association of waist circumference, chemerin, and retinol binding protein (RBP)-4 with inflammation in men with central obesity.METHODS: The research was conducted with a crosssectional design involving 68 centrally obese male subjects aged 30 to 60 years old, with waist circumference (WC) >90 cm. All subjects fulfilled the inclusion and exclusion criteria. Anthropometric parameters, fasting glucose, creatinine, SGOT, SGPT and hsCRP were measured. Serum concentrations of chemerin and RBP4 were measured by ELISA.RESULTS: The trend lines showed that chemerin, RBP4, and hsCRP increased with WC. Pearson correlation test showed a positively significant correlation between WC and hsCRP (r=0.242, p<0.05); and also between chemerin and hsCRP (r=0.244, p<0.05) and RBP4 (r=0.321, p<0.01). Subjects were stratified into four groups based on their chemerin and RBP4 levels (high chemerin/high RBP4, high chemerin/low RBP4, low chemerin/high RBP4, or low chemerin/low RBP4). Subjects who were in the high chemerin/low RBP4 group were more likely to have high level of inflammation (47.6%), but subjects with high chemerin/high RBP4 showed low level of inflammation (42.9%) as compared with the other three groups.CONCLUSIONS: We concluded that increased WC was correlated with elevated levels of chemerin, RBP4, and hsCRP. High chemerin was correlated with increased level of RBP4 as well as with high level of inflammation.KEYWORDS: waist circumference, chemerin, RBP4, hsCRP, inflammation

Abstract

BACKGROUND: Uric acid is the end product of purine metabolism. Hyperuricemia can occur because of decreased excretion, increased production and/or a combination of both mechanisms. Elevation of uric acid in the blood (>5.5 mg/dL) in children is associated with the occurrence of essential hypertension. The relevance of pediatric hyperuricemia into adult hypertension have been widely studied.CONTENT: The high percentage of children and adolescents with metabolic syndrome who had an elevated concentration of uric acid could be of great concern if it were concluded that uric acid was an independent risk factor for cardiovascular disease. The minimum age that has shown blood pressure is significantly associated with adult life is unknown. There are a number of possible explanations for the phenomenon of blood pressure tracking, including hyperuricemia. Several pathophysiological mechanisms increase uric acid with cardiovascular damage through proliferation of vascular smooth muscle cells, stimulate inflammatory path, and then prothrombotic effects triggered by the activation of platelets. Once vascular lesion has appeared, then arises the sodium-sensitive hypertension, although uric acid levels have returned to normal. Persistant mechanism of sodium sensitivity is caused by renal ischemia that leads to activation of the renin-angiotensin system, renal vasoconstriction and increased reabsorption of salt. This supports better understanding of the link between childhood hyperuricemia and adulthood hypertension.SUMMARY: Childhood hyperuricemia is an independent risk factor of hypertension and is ‘linked to’ adult blood pressure.KEYWORDS: uric acid, hyperuricemia, primary hypertension, children, adult

Abstract

BACKGROUND: Obesity is a major health problem in the world today. Obesity is closely associated with insulin resistance and type 2 diabetes. Epidemiological studies have shown that obese persons are in a state of insulin resistance, however, most of them do not progress to type 2 diabetes. This occurs because the beta cell function is still good enough for maintaining normal glucose level. Obestatin and visfatin are cytokines that are known to have a role in beta cell function. The aim of this study was to assess the relationship between visfatin and obestatin and Homeostasis Model Assessment of beta cell function (HOMA-β) and Homeostasis Model Assessment of insulin resistance (HOMA-IR).METHODS: This was a cross-sectional study involving 80 central obesity men with waist circumference >90 cm, age 30-65 years old. Visfatin and obestatin were measured by ELISA method. Beta pancreas cell dysfunction and insulin resistance were calculated by HOMA model.RESULTS: Our study showed a correlation between visfatin and HOMA-β (r=0.244 and p = 0.029) and visfatin with HOMA-IR (r=0.287 and p=0.001) and no correlation was found between obestatin with HOMA-β (r=0.010 and p=0.990) and obestatin with HOMA-IR (r=0.080 and p=0.480). We also found visfatin and obestatin concentrations were fluctuative depending on the measurements of the waist circumferences.CONCLUSIONS: High visfatin and low obestatin concentration were independently associated with increased beta pancreas cell dysfunction and insulin resistance.KEYWORDS: obesity. visfatin, obestatin, beta cell dysfunction (HOMA-β), insulin resistance (HOMA-IR)

Abstract

BACKGROUND: Central obesity is the accumulation of visceral (intra-abdominal) fat and is strongly known to be associated with insulin resistance and type 2 diabetes mellitus (T2DM). Obesity can cause adipocyte hypertrophy that results in dysregulation of adipokine expression. The abnormal function of adipocytes may play an important role in the development of a chronic low-grade proinflammatory state associated with obesity. Adiponectin, retinol binding protein (RBP)-4 and fetuin-A play a role in the pathophysiology of insulin resistance. Expression of fetuin-A is increased due to fat accumulation in the liver. Elevated concentration of fetuin-A in the circulation can impair insulin signaling in muscle and liver as well as suppress adiponectin secretion, although its molecular mechanism is still unclear. The aim of this study was to identify the relationship of fetuin-A, adiponectin, RBP-4 and hsCRP with insulin resistance in obese non diabetic men.METHODS: This was an observational study with a cross-sectional design. The study subjects were 64 men with non diabetic abdominal obesity, characterized by waist circumference of 98.47 ± 5.88 cm and fasting blood glucose of 85.75±8.36 mg/dL.RESULTS: This study showed that fetuin-A was positively correlated with HOMA-IR in obese non diabetic men with insulin resistance (r = 0.128; p = 0.570), although not significant. Fetuin-A was found to be correlated with adiponectin, RBP-4 and hsCRP (r=0.150; p=0.233; r=0.050; p=0.711; r=-0.04; p=0.445), although not significant.CONCLUSIONS: The concentration of fetuin-A showed a tendency to be positively correlated with HOMA-IR and with RBP-4 in obese non diabetic men, although statistically not significant. The concentration of fetuin-A showed a tendency to be negatively correlated with adiponectin and hsCRP although statistically not significant. There was no interrelationship between fetuin-A, adiponectin, RBP-4, hsCRP and HOMA-IR. Elevated concentrations of fetuin-A were noted in obese subjects, which in turn might impair insulin signaling. This finding might suggest that fetuin-A may represent a new target for the prevention of insulin resistance. Further studies might be needed on obese population with fatty liver.KEYWORDS: fetuin-A, adiponectin, RBP-4, hsCRP, insulin resistance

Abstract

BACKGROUND: Inflammation is a central feature of the atherosclerotic process particularly in obesity. hsCRP, a marker of inflammation, may be directly involved in all phases of atheroslerosis by complement activation, apoptosis, vascular cell activation, monocyte recruitment, lipid accumulation and thrombosis. Inflammation has a causal relationship with cysteine proteases including cathepsin S. Therefore, cathepsin S is considered as a molecular link between obesity and atherosclerosis. An imbalance between elastolytic cysteine proteases, cathepsin S and its inhibitor, cystatin C, is involved in the pathogenesis of atherosclerosis. Some studies have shown that increased circulating levels of cathepsin S, hsCRP and cystatin C in inflammatory conditions contribute to atherosclerosis. This study was conducted to investigate the associations between ox-LDL and cathepsin S, and cystatin C and hsCRP in men with central obesity.METHODS: This was a cross-sectional study involving 71 male subjects with central obesity (waist circumference ≥90 cm), with no renal dysfunction, aged 30-60 years.RESULTS: Cathepsin S did not have a significant correlation with ox-LDL (r=0.158, p=0.096). ox-LDL had positive correlation with cystatin C (r=0.156; p=0.029) and hsCRP (r=0.204; p=0.045), and cathepsin S/cystatin C ratios (r=0.360; p=0.024) at level >91 U/L (median ox-LDL).CONCLUSIONS: There were associations between ox-LDL and cystatin C, hsCRP and cathepsin S/cystatin C ratios in men with central obesity.KEYWORDS: obesity, inflammation, atherosclerosis, hsCRP, cystatin C, cathepsin S, ox-LDL

Abstract

BACKGROUND: Osteoprotegerin (OPG) is produced by a variety of tissues including those of the cardiovascular system. Recent clinical studies have suggested a significant correlation between elevated OPG serum level and cardiovascular mortality. Since coronary artery calcification (CAC) is positively associated with cardiovascular disease (CVD) events, we carried out a study to investigate whether OPG serum level is associated with the severity of CAC in non diabetic centrally obese men.METHODS: A cross sectional study was done on seventy non diabetic centrally obese men. CAC score was determined by using dual source computed tomography (DSCT). OPG serum level was measured by enzyme-linked immunosorbent assay (ELISA) method. Statistical analysis was done with SPSS for windows ver 16. ANOVA was performed to analyze mean, maximum, minimum value, and standard deviation. Spearman correlation test was performed to determine the correlation between OPG serum level and CAC score. Significance value was defined as alpha level=0.05 based on two-tailed tests.RESULTS: OPG serum level was significantly correlated with CAC score. The severity of CAC increased with the increase of OPG level. Age was significantly correlated with OPG serum level and CAC score.CONCLUSIONS: Our data show that serum OPG level was associated with the severity of CAC, which highlights that OPG could be involved in the progression of CAC in non diabetic obese men.KEYWORDS: obesity, vascular calcification, osteoprotegerin, coronary artery calcification
