Stem cell-derived extracellular vesicles for renal repair: Do cardiovascular comorbidities matter?

Stem cell-derived extracellular vesicles for renal repair: Do cardiovascular comorbidities matter? Am J Physiol Renal Physiol. 2019 Oct 21;: Authors: Eirin A, Lerman LO Abstract Extracellular vesicle (EV)-based regenerative therapy has shown promising results in preclinical models of renal disease and might be useful for patients with several forms of chronic kidney disease (CKD). However, individuals with CKD often present with comorbidities, including obesity, hypertension, diabetes, or even metabolic syndrome, which may alter the endogenous characteristics and impair the reparative capacity of stem cells and their daughter EVs. This brief review summarizes evidence of alterations in the morphology, cargo, and function of mesenchymal stem cells (MSCs) and MSC-derived EVs in the face of cardiovascular disease. We further discuss the important ramifications for their use in patients with kidney disease. PMID: 31630544 [PubMed - as supplied by publisher]

sti R Abstract Protein carbonylation is a marker of oxidative protein damage, that is likely involved in the pathogenesis of several diseases. The aim of this study was to evaluate the protein carbonyl (PC) groups in different clinical conditions. It included different groups of subjects: 81 trained subjects; 23 subjects with mild essential hypertension; 31 middle-aged subjects with metabolic syndrome (MS); 106 subjects with MS not selected for age (subdivided into two subgroups, with and without diabetes mellitus); 91 obese adults subdivided in two subgroups (BMI 30-35 Kg/m2 and BMI > 35 kg/m2); 48 subject...

This study enrolled 14983 eligible subjects stratified into metabolically healthy normal weight (MHNW), metabolically healthy overweight (MHOW), metabolically healthy obesity (MHO), metabolically unhealthy normal weight (MUNW), metabolically unhealthy overweight (MUOW), and metabolically unhealthy obesity (MUO) according to body mass index and metabolic syndrome status (ATP-III criteria). The metabolic healthy phenotype was defined as the absence of both metabolic syndrome and any known diabetes, coronary artery disease, stroke, hypertension or dyslipidemia. Early and advanced CKD were defined as eGFR

CONCLUSIONS: MS is correlated with CKD in both premenopausal and postmenopausal women, and the association is dependent on diabetes, hypertension, and hyperuricemia in premenopausal women but not in postmenopausal women. PMID: 31340922 [PubMed - in process]

Conclusion: The risk factors like high TG, low HDL, high BP, and high fasting glucose were found higher particularly in younger population which may lead to diagnosis &complications of diabetes, hypertension and lipid abnormality. Due to changing physiology in young and middle age population these individuals are moving towards metabolic syndrome easily and needs frequent monitoring, preventive checkups, and lifestyle changes to prevent complications.

Authors: Mok CC Abstract INTRODUCTION: The metabolic syndrome (MetS) is now recognized as a chronic proinflammatory and prothrombotic state that aggravates insulin resistance, oxidative injury and cardiovascular risk. MetS is more prevalent in patients with systemic lupus erythematosus (SLE), a prototype of systemic autoimmune disease associated with premature atherosclerosis that cannot be accounted by traditional vascular risk factors alone. Dysregulation of the cytokines and adipokines is a common feature in both SLE and MetS, suggesting a complex relationship among autoimmunity, obesity, inflammation and athero...

In this study, we investigated the genetic contribution to renal disease in Tiwi Islanders by conducting a GWAS, in which associations were tested between SNP genetic variants and single measure ACR levels. A number of nominally significantly associated SNPs were identified. These SNPs did not reach genome wide significance, probably due to the small sample size. The top eight SNPs were re-tested for association in a separately collected cohort from the same population. Four of these SNPs were significantly associated with ACR in the replication sample (p

Conclusion Activation of the Nrf2-dependent antioxidant system plays an important role in cell defense against oxidative stress damage, whereas the insufficiency of the Nrf2 system is associated with multiple aspects of the genesis and progression of metabolic diseases, posing a great risk to the cardiovascular system (Figure 1). The systemic increase of Nrf2 activity by several activators may be beneficial in the treatment of metabolic diseases. In addition, selective upregulation of Nrf2 genes may represent a potential therapy in obesity, diabetes and atherosclerosis. Looking to the future, experimental research that el...
