Resistin levels in the gingival crevicular fluid among diabetic and non-diabetic chronic periodontitis patients

It is of interest to document theresistin levels in chronic periodontitis patients (CP) with or without type 2 diabetes mellitus (T2DM) in the gingival crevicular fluid (GCF).The expression of resistin was significantly higher in chronic periodontitis when compared to the periodontally healthy groups. Resistin levels were high in CP and T2DM. Therefore, GCF resistin levels is of interest as a potential incendiary marker for periodontitis with T2DM.</jats:p

<i>In vitro</i> studies on inhibitory effect of proanthocyanidins in modulation of neutrophils and macrophages

141-147The role of proanthocyanidins (PC), a novel flavonoid extracted from grape seeds was studied in vitro in the modulation of neutrophil and macrophage function. We attempted to assess the levels of non-enzymatic and enzymatic mediators in the presence or absence of PC in 4-phorbol-12--myristate-13-acetate (PMA)-stimulated neutrophils isolated from humans and rats, E. coli endotoxin-stimulated macrophages and macrophages isolated from E. coli endotoxin-induced experimental periodontitis in rats. Addition of PC at a concentration of 50 µg/ml effectively blocked the release of reactive oxygen species (ROS) and reactive nitrogen species (RNS) and exhibited a marked inhibition of myeloperoxidase (MPO) and lysosomal enzymes (p<0.001), as compared to PMA-stimulated neutrophils (human and rats) and neutrophils isolated from experimental periodontitis in rats. The levels of ROS, RNS and lysosomal enzymes were found to be elevated (p<0.001) and addition of PC significantly (p as compared to those from E. coli endotoxin-stimulatedmacrophages from rats and macrophages isolated from experimental periodontitis in rats (p<0.001). Thus, the study demonstrated that PC decreased the levels of ROS and RNS and also inhibited the MPO and lysosomal enzymes activities in experimental periodontitis in rats. In addition, this study clearly indicated that PC could be developed as an effective antiinflammatory agent

Diabetes Mellitus and Periodontitis: Bidirectional Relationship

Type 2 diabetes mellitus and chronic periodontitis hold a close relationship that has been the focus of many researches. Periodontitis is a common chronic inflammatory disease characterised by destruction of the supporting structures of the teeth. Evidences stated that diabetes is a major risk factor for periodontitis; susceptibility to periodontitis is increased by approximately threefold in people with diabetes. There is a clear relationship between degree of hyperglycaemia and severity of periodontitis. The mechanisms that underpin the links between these two conditions are not completely understood, but involve aspects of immune functioning, neutrophil activity, and cytokine biology. There is emerging evidence to support the existence of a two-way relationship between diabetes and periodontitis, with diabetes increasing the risk for periodontitis, and periodontal inflammation negatively affecting glycaemic control. Oral and periodontal health should be promoted as integral components of diabetes management.</jats:p

Therapeutic effects of proanthocyanidins on the pathogenesis of periodontitis— An overview

83-93Periodontitis is a bacterially induced chronic inflammatory disease that destroys the connective tissue and bone that support teeth. Bacteria initiates periodontitis and destruction of the alveolar bone and periodontal connective tissue is clearly observed. But, the events occuring between these two points of time remain obscure and this study focusses on these aspects. The proanthocyanidins (PC) have variable pharmacological and nutraceutical benefits including improvement of ischemic cardiovascular disease, prevention of atherosclerosis and antiarthritic, anticancer and antimicrobial activities. The benefits associated with the antioxidant activity of PC have been evaluated both in vivo and in vitro. But, reports on the ameliorative effects of PC on oral diseases and specifically on periodontitis are very few. Hence, a novel attempt is made to review the possible protective effects of PC and its mechanism of action in periodontitis and also to show whether PC could be developed as a therapeutic agent for periodontitis

A Prospective Study of Urinary Albumin to Creatinine Ratio and Its Associated Causes

Urine albumin-to-creatinine ratio have predictive values for hypertension, diabetes mellitus, renal dysfunction etc. Albumin-to-creatinine ratio represents the severity of proteinuria,  indicates high probability of damage to glomerular filtration capacity of the kidney and is of great diagnostic relevance. Emerging data suggested that reduction of albuminuria leads to reduced risk of adverse renal and cardiovascular events but also steps should be taken to suppress albuminuria to prevent future renal and cardiovascular adverse events. This review discusses the association between albuminuria and adverse cardiovascular and renal outcomes in type 2 diabetes and hypertension. This study aimed to review the association between normal ranges of urine albumin-to-creatinine ratio to cardiovascular and all-cause mortality.</jats:p

Role of Adipokines in Obesity and Obesity related Metabolic Disorders

Obesity is defined as an excessive growth of adipose tissue. It is associated with over nutrition, which impairs systemic metabolic homeostasis. Adipokines secreted by adipose tissue could play an vital role in the development of obesity and associated metabolic disorders includes insulin resistance, inflammation, hypertension, cardiovascular risk etc. Adipokines will be of importance in the development of novel therapies for obesity-associated diseases. This review emphasises on obesity and the role of some Adipokines in obesity and related metabolic disorders.</jats:p
