Abstract

BACKGROUND: The epidemic of obesity and type 2 diabetes presents a serious challenge to scientific and biomedical communities worldwide. There has been an upsurge of interest in the adipocyte coincident with the onset of the obesity epidemic and the realization that adipose tissue plays a major role in the regulation of metabolic function.CONTENT: Adipose tissue, best known for its role in fat storage, can also suppress weight gain and metabolic disease through the action of specialized, heat-producing adipocytes. Brown adipocytes are located in dedicated depots and express constitutively high levels of thermogenic genes, whereas inducible ‘brown-like’ adipocytes, also known as beige cells, develop in white fat in response to various activators. The activities of brown and beige fat cells reduce metabolic disease, including obesity, in mice and correlate with leanness in humans. Many genes and pathways that regulate brown and beige adipocyte biology have now been identified, providing a variety of promising therapeutic targets for metabolic disease.SUMMARY: The complexity of adipose tissue presents numerous challenges but also several opportunities for therapeutic intervention. There is persuasive evidence from animal models that enhancement of the function of brown adipocytes, beige adipocytes or both in humans could be very effective for treating type 2 diabetes and obesity. Moreover, there are now an extensive variety of factors and pathways that could potentially be targeted for therapeutic effects. In particular, the discoveries of circulating factors, such as irisin, fibroblast growth factor (FGF)21 and natriuretic peptides, that enhance brown and beige fat function in mice have garnered tremendous interest. Certainly, the next decade will see massive efforts to use beige and brown fat to ameliorate human metabolic disease.KEYWORDS: obesity, white adipose tissue, brown adipose tissue, beige adipose tissue, adipose organ, thermogenesis, energy expenditure

Abstract

BACKGROUND: Abortion remains a problem in the obstetric care as it is one of the causes of maternal and fetal death. Bleeding or miscarriage threat in the first trimester comprises 20% to 25% of all pregnant women, and 50% of them will end as spontaneous abortion. The major cause of maternal death in abortion is hemorrhage. Some recent studies have indicated that MMP-9 is important in the process of embryo implantation into the endometrium and spontaneous abortion occurs when there is an overwhelming increase of MMP-9. This data indicate the importance of a further research to elucidate the role of MMP-9 in spontaneous abortion.METHODS: This was a cross sectional study, included 70 pregnant women with gestational age <20 weeks who came for examination and treatment at the Department of Obstetrics and Gynecology, Medical Faculty of Padjadjaran University/Hasan Sadikin Hospital, Bandung. RESULTS: There were differences in the MMP-9 levels in spontaneous abortion compared to normal pregnancy and MMP-9 had a cut-off point >1221.7 with the sensitivity of 48.6% specificity of 80%, and accuracy of 60.9%.SUMMARY: The MMP-9 level in spontaneous abortion was higher than in normal pregnancy.KEYWORDS: MMP-9, spontaneous abortion, normal pregnancy

Abstract

BACKGROUND: Identifying risk factors for acute coronary syndrome (ACS) is important for both diagnostic and prognostic purposes. Abnormal platelet parameters, mainly platelet count (PC), mean platelet volume (MPV) and platelet distribution width (PDW) are thought to be among these risk factors because platelet activation plays a pivotal role in ACS. PDW is a more specific marker of platelet activation, since it does not increase during simple platelet swelling. In this study, the comparison of risk factors along with the PDW between Non ST-Elevation ACS (NSTEACS) and ST-Elevation ACS (STEACS) were investigated.METHODS: This is a cross-sectional study, patients with ACS that admitted at dr.Wahidin Sudirohusodo General Hospital Makassar since December 2014 to March 2015 who undergo coronary angiography were enrolled. All data variables were taken according to the medical record. PDW was taken on first blood examination at hospital admission. Data was significant if p-value <0.05 and was processed with SPSS version 16.RESULTS: A total of 63 patients were enrolled. There were significantly higher PDW (p=0.047) in STEACS group (13.7±2.0 fL) than in NSTEACS group (12.6±2.3 fL). There were a significant positive correlation between PDW value and SYNTAX scores (Pearson, r=0.552, p=0.000). Cardiovascular risk factors such as history of ACS before (p=0.049 & OR=10.216) and dyslipidemia (p=0.049 & OR=3.915) along with PDW (p=0.003 & OR=1.733) were significant predictor of the incidence of multivessel disease in patient with ACS.CONCLUSION: An increased PDW may predicting more severe disease in ACS based on incidence of STEACS and multivessel disease more often and higher SYNTAX score.KEYWORDS: platelet distribution width, PDW, acute coronary syndrome, ACS, multivessel disease, SYNTAX

Abstract

BACKGROUND: Thrombus is a main cause of cardiac death. Therefore identifying which coronary artery plaque is vulnerable to rupture is a critical step for cardiac intervention to prevent future cardiac events. Systemic biochemical markers are used for predicting rupture of coronary plaque or identifying stenotic coronary artery plaque(s) vulnerable to rupture.METHODS: Blood samples of 2x24 locations (2x10 controls, 2x12 stable plaques and 2x2 unstable plaques) of 13 patients to undergo stent placement were taken from an artery which showed no stenosis (control), 70% or more stenosis of stable plaques and unstable plaques, respectively. The blood samples were taken by using microcatheter distally and proximally. Concentrations of MPO, MMP-9, SPLA2 and CD40L of each sample were assayed.RESULTS: Concentration of MMP-9 in unstable coronary artery plaque (94.7+14.4 ng/ml) significantly increased compared with that of stable coronary artery plaque (71.0+67.8 ng/ml, p=0.024). SPLA2 concentration significantly decreased in unstable coronary artery plaque (45.9+14.0 pg/ml) compared with that of stable coronary artery plaque (80.9+39.3 pg/ml, p=0.015). Nine of ten studied subjects showed an average of 14.5% (range: 0.0-28.8%) decrease of the SPLA2 concentration in stable plaques compared with that of the non-stenotic coronary artery.CONCLUSION: MMP-9 increased in unstable coronary artery plaque compared with that of stable coronary plaque. Unstable coronary artery plaques absorbed SPLA2 from the vasculars more than the stable plaques and control plaques. MMP-9 and SPLA2 may be used as markers of stability of a plaque in coronary artery in relation to its rupture potential.KEYWORDS: stable and unstable plaque, myeloperoxidase, matrix metalloproteinase-9, secretory phospholipase A2, CD40 Ligand

Abstract

BACKGROUND: Obesity is closely associated with atherosclerosis risk and cardiovascular disease. Novel cardiovascular risk biomarkers such as Urine Albumin/Creatinine Ratio (UACR), High Sensitivity C-Reactive Protein (hsCRP) and N-Terminal pro Brain Natriuretic Peptide (NT-proBNP) have been observed to predict cardiovascular disease in the general population. The aim of this study was to observe the correlation of UACR, hsCRP and NT-proBNP with atherosclerosis (OxLDL) in centrally obese men.METHODS: The study was observational with a cross sectional design done on 76 male subjects aged 30–50 years with central obesity and mean of age of 37 years. Urine albumin was determined by PEG enhanced immunoturbidimetric assay, urine creatinine by Jaffe without deproteinase, hsCRP by chemiluminescent immunometric assay, NT-proBNP by electrochemiluminescence (ECLIA) and OxLDL by ELISA.RESULTS: There was significant correlation between hsCRP and OxLDL (r=0.230, p=0.046). There was no significant correlation between UACR and OxLDL (r=-0.138, p=0.236), neither between Log NT-proBNP and OxLDL (r=-0.173, p=0.136).CONCLUSIONS: Atherosclerosis was significantly correlated with hsCRP (low grade inflammation).KEYWORDS: NT-proBNP, UACR, hsCRP, OxLDL, atherosclerosis

Abstract

BACKGROUND: Maternal circulating leptin, placental leptin gene expression and protein levels are increased in preeclampsia as compared with those in normal pregnancy. Increased serum leptin levels in preeclampsia which correspond with increased gestational age can be used independently or with other parameters as a marker for the severity of preeclampsia. The advantages of this examination in identifying preeclampsia severity are its simplicity, fast result, low cost and applicability.METHODS: A cross-sectional study was conducted in delivery room, polyclinic of Dr. M. Djamil Hospital, and Biomedical Laboratories of Medical Faculty of Andalas University from December 2013 to April 2014. The samples were collected from 68 women with singleton pregnancy in their third trimester (>28 weeks) presenting to the polyclinic and the delivery room of Dr. M. Djamil hospital. Differences in maternal serum leptin between preeclampsia and normal pregnancy were determined using t-test and Wilcoxon test for data with and without normal distribution, respectively, where p<0.05 indicating a significant results.RESULTS: The mean maternal serum leptin levels in normal pregnancy and preeclampsia were 1588.7964 ± 8.01074 ng/mL and 1608.1725 ± 6.69579 ng/mL, respectively. Thus, there is a statistically significant difference in mean maternal serum leptin levels between the normal pregnancy and preeclampsia (p<0.05).CONCLUSION: There are significant differences in maternal serum leptin levels between women with normal pregnancy and preeclampsia.KEYWORDS: leptin, preeclampsia, pregnancy

Abstract

BACKGROUND: Obesity is closely associated with atherosclerosis. Obesity and atherosclerosis are closely associated with inflammatory disease. Atherosclerosis constitutes a multifactorial disorder affecting the arterial wall, which is initiated by dyslipidemia and excerbated by inflammation. Plasma levels of lipoprotein-associated phospholipase A2 (Lp-PLA2) and oxidized low density lipoprotein (ox-LDL) have been identified as risk factors for cardiovascular disease.  Lp-PLA2 is the sole enzyme responsible for the hydrolysis of oxidized phospholipids (oxPL) on LDL particles in atherosclerosis plaque. Plasma level of oxLDL is associated with inflammation and plays an important role in the development of atherosclerosis. The aim of this study was to assess the correlation between Lp-PLA2 and atherosclerosis (oxLDL) in centrally obese men.METHODS: This was a cross-sectional study involving 71 men with central obesity with waist circumference >90 cm, aged 30-60 years old. Lp-PLA2 measurement was done by sandwich enzyme immunoassay. oxLDL measurement was done by ELISA method. RESULTS: Results of this study showed that central obesity correlated positively with oxLDL (r=0.258; p=0.040) and Lp-PLA2 >422 ng/mL correlated positively with oxLDL (r=0.331; p=0.042).CONCLUSIONS: We conclude that there is a correlation of Lp-PLA2 with atherosclerosis (oxLDL) in men with central obesity.KEYWORDS: obesity, Lp-PLA2, oxLDL, atherosclerosis

Abstract

BACKGROUND: Gamma glutamyltransferase (GGT) was reported recently to be associated with inflammation, oxidative stress and increased amino acid. However, role of GGT in insulin resistance pathomechanism is not exactly known. Therefore correlation of GGT with inflammation, oxidative stress and elevated amino acid, in men with central obesity need to be confirmed.METHODS: A cross-sectional study was designed. Men with central obesity were recruited and selected. Anthropometric parameters, creatinine, hs-CRP, fasting glucose, fasting insulin, glutathione peroxidase (GPx) activity, GGT, plasma total cysteine (tCys) and fatty liver were measured. Subjects were then divided in 4 groups based on waist circumference (WC) and fatty liver: Group I: WC ≤100 cm, without fatty liver; Group II: WC ≤100 cm, with fatty liver; Group III: WC >100 cm, without fatty liver; Group IV: WC >100 cm, with fatty liver. All biochemical characteristics in each group were then statistically analyzed.RESULTS: Seventy-two men with central obesity were selected. Numbers of subjects in each group were: Group I: n=33; Group II: n=5; Group III: n=17; Group IV: n=17. We found significant difference of HOMA-IR between Group I and IV, significant correlation between GGT and HOMAIR, and significant negative correlation between tCys with HOMA-IR in Group IV.CONCLUSION: GGT was significantly correlated with HOMA-IR in men with WC >100 cm and fatty liver. Further investigation with more subjects is necessary to determine clear GGT cut-off to distinguish subjects with fatty liver and insulin resistance.KEYWORDS: GGT, hs-CRP, GPx, tCys, HOMA-IR, insulin resistance

Abstract

BACKGROUND: Neopterin is a soluble biomarker of monocyte activation and its increased concentration might be expressed in atherosclerosis. Until recently, there has been lacking of information on the prognostic role of neopterin in acute coronary syndromes (ACS). The study was aimed at measuring the associations between elevated serum neopterin and increased risk of cardiovascular (CV) events in ACS.METHODS: This was a prospective cohort study, recruited 71 ACS patients from January 31 through August 31, 2007 in Sanglah Hospital of Udayana School of Medicine, Denpasar – Bali. Cardiovascular events, such as: CV death, recurrent myocardial infarction, stroke and recurrent myocardial ischemia were previously defined. Relative risk and survival rate were measured successively by Cox proportional model and Kaplan-Meier curve.RESULTS: Of 71 ACS patients aged 56.8 ± 9.5 years, 21 (29.5%) subjects underwent CV events. Overall mean followup was 151.6 (95% CI: 129.7 – 173.5) days. Baseline characteristic were similarly distributed between groups with the highest quartile neopterin level (≥ 14.7 nmol/L) than those with lowest quartile (≤ 6.2 nmol/L). Patients with the highest quartile had the worst survival curve than those with the lowest quartile (log-rank test; P = 0.047). On Cox proportional model, relative risk of highest quartile group was 5.84 (95% CI: 1.19 – 28.47; P = 0.029) compared to lowest quartile, after being adjusted with other predictors.CONCLUSIONS: Elevated serum neopterin is associated with increased risk of CV events in acute coronary syndromes.KEYWORDS: neopterin, cardiovascular events, acute coronary syndromes

Abstract

BACKGROUND: The investigation of novel circulating serum and plasma biomarkers in patients with cardiovascular disease has been accelerating at a remarkable pace. New markers or tests are often presented too early to the medical profession, potentially leading to overuse and, thus, extra burden and costs to patients, the healthcare industry, and the economy. The challenge for clinicians and medical researchers is how to optimally apply existing and new markers/tests.CONTENT: Biomarkers are biological parameters that can be objectively measured and quantified as indicators of normal biologic processes, pathogenic processes, or responses to a therapeutic intervention. Typically thought of as disease process screening, diagnosing, or monitoring tools, biomarkers may also be used to determine disease susceptibility and eligibility for specific therapies. Cardiac biomarkers are protein components of cell structures that are released into circulation when myocardial injury occurs. They play a pivotal role in the diagnosis, risk stratification, and treatment of patients with chest pain and suspected acute coronary syndrome (ACS) as well as those with acute exacerbations of heart failure.SUMMARY: Active investigation has brought forward an increasingly large number of novel candidate markers but few have withstood the test of time and become integrated into contemporary clinical care because of their readily apparent diagnostic, prognostic, and/or therapeutic utility. With regard to the more novel biomarkers, careful thought is needed with regard to the appropriate target populations for discovery and validation, as well as the criteria used to sort out the contenders from the pretenders.KEYWORDS: biomarker, cardiovascular disease, atherosclerosis, acute myocardial infarction, heart failure, risk stratification, diagnosis, prognosis
