Abstract

BACKGROUND: Obesity is closely related to chronic, low grade systemic inflammation (metaflammation) and it leads to further metabolic complications such as hypertension, atherosclerosis, and type 2 diabetes due to the adipocytokine imbalance. This study was carried out to assess the correlation between progranulin, granulin, adiponectin and visceral adipose tissue-derived serine protease inhibitor (Vaspin) with metaflammation (high sensitivity C-reactive protein (hs-CRP)) in centrally obese men.METHODS: This study was observational with a cross sectional design involving 60 men aged 30-60 years, consisted of 43 obese men (waist circumference (WC) ≥90 cm) and 13 non obese men (WC <90 cm), with no hypertension, and no renal dysfunction. Anthropometric parameters, creatinine, serum glutamic oxaloacetic transferase (SGOT), serum glutamic piruvic transferase (SGPT) and hs-CRP levels were measured. Serum concentrations of progranulin, granulin, adiponectin and Vaspin were measured by ELISA.RESULTS: This study showed in obese men a significant correlation between hs-CRP and Vaspin (r=0.305; p=0.046), non-significant correlation between hs-CRP and progranulin (r=0.048; p=0.758), between hs-CRP and granulin (r=-0.223; p=0.150), also between hs-CRP and adiponectin (r=-0.121; p=0.439). Similar patterns were observed between adipokines level and WC. There were 3 patterns showing increase or decrease of adipokines value with WC between 80-86 cm; subsequently the pattern tended to become flat with WC between 86-105 cm, then showing increase or decrease of adipokines value with WC >105 cm.CONCLUSION: We found metaflammation (hs-CRP) was significantly correlated with Vaspin, but not with progranulin, granulin and adiponectin, in obese men. We suggest the possibility of a dynamic expression of adipokines related to WC that are subjected to adipocytes hypertrophy-hyperplasia phenomenon.KEYWORDS: progranulin, granulin, adiponectin, Vaspin, hs-CRP, metaflammation, central obesity

Abstract

BACKGROUND: MicroRNAs (miRNAs) are ~22-nucleotide noncoding RNAs with critical functions in multiple physiological and pathological processes. An explosion of reports on the discovery and characterization of different miRNA species and their involvement in almost every aspect of cardiac biology and diseases has established an exciting new dimension in gene regulation networks for cardiac development and pathogenesis.CONTENT: Alterations in the metabolic control of lipid and glucose homeostasis predispose an individual to develop cardiometabolic diseases, such as type 2 diabetes mellitus and atherosclerosis. Work over the last years has suggested that miRNAs play an important role in regulating these physiological processes. Besides a cell-specific transcription factor profile, cell-specific miRNA-regulated gene expression is integral to cell fate and activation decisions. Thus, the cell types involved in atherosclerosis, vascular disease, and its myocardial sequelae may be differentially regulated by distinct miRNAs, thereby controlling highly complex processes, for example, smooth muscle cell phenotype and inflammatory responses of endothelial cells or macrophages. The recent advancements in using miRNAs as circulating biomarkers or therapeutic modalities, will hopefully be able to provide a strong basis for future research to further expand our insights into miRNA function in cardiovascular biology.SUMMARY: MiRNAs are small, noncoding RNAs that function as post-transcriptional regulators of gene expression. They are potent modulators of diverse biological processes and pathologies. Recent findings demonstrated the importance of miRNAs in the vasculature and the orchestration of lipid metabolism and glucose homeostasis. MiRNA networks represent an additional layer of regulation for gene expression that absorbs perturbations and ensures the robustness of biological systems. A detailed understanding of the molecular and cellular mechanisms of miRNA-mediated effects on metabolism and vascular pathophysiology could pave the way for the development of novel diagnostic markers and therapeutic approaches.KEYWORDS: microRNA, lipid metabolism, glucose homeostasis, vascular endothelium, vascular smooth muscle, atherosclerosis

Abstract

BACKGROUND: There is a prevalence increase of overweight and obesity in Indonesia. Central obesity can lead a variety of chronic diseases through the inflammatory process. There are some markers for low-grade chronic inflammatory, such as cathepsin S, high sensitivity C-reactive protein (hs-CRP), interleukin-1- beta (IL-1β). To our current interest that central obesity can lead to various chronic diseases through the inflammatory process, we conducted a study to investigate correlation of Cathepsin S, hs-CRP, IL-1β in men with central obesity.METHODS: A cross-sectional study was conducted. Seventy-eight selected subjects were examined to collect anthropometric data and prepared for sample collection. Collected samples were processed for the following biochemical analyses: fasting glucose, high density lipoprotein (HDL)-cholesterol, triglyceride, serum glutamic oxaloacetic transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), cathepsin S, hs-CRP, and IL-1β. Data distribution and variable correlation were then statistically analyzed.RESULTS: There were significant correlations between waist circumference (WC) and cathepsin S (p=0.030; r=0.214), hs-CRP and cathepsin S (p=0.007; r=0.276), triglyceride and IL-1β (p=0.019; r=-0.235), WC and systolic blood pressure (SBP) (p=0.003; r=-0.312), WC and fasting glucose (p=0.000; r=0.380), WC and body mass index (BMI) (p=0.000; r=0.708).CONCLUSION: Our study showed that cathepsin S was correlated with central obesity, suggesting that cathepsin S could be a potential inflammatory marker in central obesity in the future.KEYWORDS: obesity, inflammation, hs-CRP, cathepsin S, IL-1β, waist circumference

Abstract

BACKGROUND: Obesity is now recognized as the main cause of the worldwide epidemic of type 2 diabetes. Obesity-associated chronic inflammation is a contributing key factor for type 2 diabetes and cardiovascular disease. Numbers of studies have clearly demonstrated that the immune system and metabolism are highly integrated.CONTENT: Macrophages are an essential component of innate immunity and play a central role in inflammation and host defense. Moreover, these cells have homeostatic functions beyond defense, including tissue remodeling in ontogenesis and orchestration of metabolic functions. Diversity and plasticity are hallmarks of cells of the monocyte-macrophage lineage. In response to interferons (IFNs), toll-like receptor (TLR), or interleukin (IL)-4/IL-13 signals, macrophages undergo M1 (classical) or M2 (alternative) activation. Progress has now been made in defining the signaling pathways, transcriptional networks, and epigenetic mechanisms underlying M1, M2 or M2-like polarized activation.SUMMARY: In response to various signals, macrophages may undergo classical M1 activation (stimulated by TLR ligands and IFN-γ) or alternative M2 activation (stimulated by IL-4/IL-13); these states mirror the T helper (Th)1–Th2 polarization of T cells. Pathology is frequently associated with dynamic changes in macrophage activation, with classically activated M1 cells implicate in initiating and sustaining inflammation, meanwhile M2 or M2-like activated cells associated with resolution or smoldering chronic inflammation. Identification of the mechanisms and molecules that are associated with macrophage plasticity and polarized activation provides a basis for macrophage centered diagnostic and therapeutic strategies.KEYWORDS: obesity, adipose tissue, inflammation, macrophage polarization

Abstract

BACKGROUND: Preeclampsia is still a significant problem worldwide. Of the many suggested mechanisms of its pathogenesis, the latest one is the balance of angiogenic factor and its relationship with hypoxia factors. The objective of this study was to observe changes or dynamic process of soluble fms-like tyrosine kinase 1 (sFlt1) as anti-angiogenic factor and hypoxia inducible factor 1-alpha (HIF-1α) as hypoxia marker in normotensive pregnancy and preeclampsia in mid-term and full-term pregnancies.METHODS: A cohort study was conducted on 36 normotensive subjects, first examination was conducted at 20-28 weeks of gestation. Then second examination was conducted at the time of preeclampsia diagnosed or full-term pregnancy. Preeclampsia was characterized by hypertension of systolic blood pressure ≥140 mmHg, diastolic blood pressure ≥90 mmHg, with two readings separated in 4-6 hours period, and/or proteinuria with urine dipstick of ≥1+ or ≥300 mg per 24 hours. Examinations of sFlt-1 and HIF-1α were done by enzyme-linked immunosorbent assay method. Statistical analysis was done using a significance level of p<0.05.RESULTS: Concentration of sFlt-1 was elevated in normotensive pregnancy and preeclampsia. Higher sFlt-1 concentration elevation was seen in preeclamptic group comparing to normotensive group, although not significant. This finding was related to the fact that investigated subjects were mostly developing mild preeclampsia merely. Comparing to normotensive group, preeclamptic group had higher HIF-1α concentration-per-week elevation, but not significant. There was a positive correlation between concentrations of sFlt-1 and HIF-1α, but not significant.CONCLUSION: sFlt-1 concentration elevation was correlated with preeclampsia. Therefore comparing to averages, changes of sFlt-1 concentrations were more important. Concentrations of HIF-1α and sFlt-1 were positively correlated.KEYWORDS: sFlt-1, HIF-1α, preeclampsia, normotension

Abstract

BACKGROUND: Surfactant replacement therapy is a recognized treatment for respiratory distress syndrome (RDS) in the newborns. Over the past 30 years, human and animal trials have been performed regarding administration of aerosolized surfactant to the injured lung, however the result has been unsatisfactory when compared with instilled surfactant delivery via endotracheal tube (ETT). This review aims to investigate the current issues, challenges and future recommendation of aerosolized surfactant therapy.CONTENT: Five randomized clinical trials in humans and 13 animal trials met the inclusion criteria and were reviewed. Most animal trials agree that this method of treatment is feasible. However, human trials presented conflicting results, and generally showed it to be ineffective. When compared with surfactant delivery via ETT, aerosolized surfactant is less effective in improving respiratory function.SUMMARY: The current data from human trials does not support the implementation of aerosolized surfactant therapy to treat newborns with RDS. Further research is necessary to improve nebulization, delivery, distribution and deposition in the lung, to investigate aerosolized surfactant delivery via ETT and to determine the appropriate dose.KEYWORDS: surfactant, aerosol, prematurity, respiratory distress syndrome

Abstract

BACKGROUND: Vascular calcification may be an important risk factor of cardiovascular disease in Chronic Kidney Disease (CKD). The pathobiology of vascular calcification in CKD is complex and involves some factors including inflammation, oxidative stress and balancing of calcification regulators. The aim of the study was to investigate the interaction between 8-isoprostane with calcification regulators such as matrix gla protein (MGP) and bone morphogenetic protein (BMP)-2 with vascular calciication in CKD.METHODS: A cross-sectional study was performed on 63 subjects undergoing haemodialysis maintenance for more than 3 months. Abdominal aortic calcification (AAC) was measured using a lateral abdominal X-ray for calcification in abdominal aorta, which is related to severity of calcific deposits at lumbar vertebral segment (L)1-L4. Serum levels of 8-isoprostane, MGP and BMP-2 were measured by enzyme-linked immunosorbent assay method.RESULTS: Results showed that 8-isoprostane levels were correlated with BMP-2 (r=0.266, p=0.018) and MGP levels (r=0.410, p≤0.001). MGP/BMP-2 levels ratio was correlated with AAC score (r=0.279, p=0.013). Subjects were then stratified into 3 groups based on AAC score: 0, 1-6 and ≥7. The highest mean of MGP levels was in AAC score 1-6 group, and the highest mean of 8-isoprostane levels was in AAC score ≥7. In the group of AAC score 0, 8-isoprostane levels were correlated with MGP levels (r=0.499, p=0.001) and MGP/BMP-2 levels ratio (r=0.291, p=0.034). In AAC score 1-6 group, 8-isoprostane levels were correlated with BMP-2 (r=0.661, p=0.005) and MGP levels (r=0.569, p=0.017). In AAC score ≥7 group, MGP levels were positively correlated with AAC score (r=0.608, p=0.041). With multivariate logistic regression analyses, we identified that increased MGP/BMP-2 levels ratio (OR=12.436; 95% CI=1.595-96.971) was an independent predictor in aortic calcification event.CONCLUSION: We concluded that regulators of calcification including calcification inhibitor and promoter related to oxidative stress, were associated with vascular calcification in CKD. MGP levels were increased in the early of calcification and MGP/BMP-2 levels ratio was a strong predictor for vascular calcification in CKD.KEYWORDS: vascular calcification, CKD, oxidative stress, 8-isoprostane, MGP, BMP-2

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
