Angiotensin blockade in diabetic patients decreases insulin resistance-associated low-grade inflammation.
Insulin-resistant states, such as metabolic syndrome and diabetes mellitus type 2 (DM2), have been associated with chronic low-grade systemic inflammation. Elevated levels of interleukin-6 (IL-6), monocyte chemoattractant protein (MCP-1) and C-reactive protein (hs-CRP), are found in patients with type 2 diabetes with and without complications. Angiotensin II (Ang II), a potent vasopressor, seems to regulate also the expression of the above inflammatory mediators acting as proinflammatory cytokine. In this study, we examined the effects of candesartan, an angiotensin receptror blocker, in the chronic low-grade inflammation observed in DM 2. ⋯ Candesartan could decrease the low-grade inflammation of type 2 DM as shown by the decrease of inflammatory mediators. Thus, angiotensin receptor blockers could be useful for treating patients with DM2 not only for their antihypertensive capacity but also for their anti-inflammatory actions.

Asymmetric dimethylarginine (ADMA) concentrations are increased in critically ill patients and may play a role in multiple organ failure. However, plasma ADMA concentrations during the development of the inflammatory response have not been documented. We measured plasma ADMA, as well as urinary excretion of its major metabolite dimethylamine, and nitrate as a marker of nitric oxide synthase (NOS) activity, in a cohort of patients undergoing elective knee arthroplasty that is known to provoke a significant inflammatory response. ⋯ Plasma ADMA concentration decreases rapidly and transiently during the first 48h of acute inflammation. This appears not be caused by increased catabolism and may reflect increased cellular partitioning. This may serve to regulate NOS activity and prevent harmful increases in inducible NOS in situations where it is not appropriate.

Randomized Controlled TrialRandomized placebo controlled trial of furosemide on subjective perception of dyspnoea in patients with pulmonary oedema because of hypertensive crisis.
To compare the administration of furosemide with placebo on the subjective perception of dyspnoea in patients with acute pulmonary oedema because of hypertensive crisis. Design Randomized, controlled and double-blinded clinical trial. ⋯ The subjective perception of dyspnoea in patients with hypertensive pulmonary oedema was not influenced by the application of a loop-diuretic. Therefore, additional furosemide therapy needs to be scrutinized in the therapy of these patients.

ReviewGenetics of type 2 diabetes: pathophysiologic and clinical relevance.
Recent genome-wide association studies enlarged our knowledge about the genetic background of type 2 diabetes. ⋯ Future studies need to target the issue of hidden heritability and to detect the causal gene variants within the identified gene loci. Improved understanding of the genetic contribution to type 2 diabetes may then help addressing the questions whether genotyping is useful to predict individual diabetes risk, identifies individual responsiveness to preventive and therapeutic interventions or at least allows for breaking down type 2 diabetes into smaller, clinically meaningful subtypes.

Coffee consumption is inversely associated with type 2 diabetes in Chinese.
Coffee consumption has been shown to be inversely associated to type 2 diabetes mellitus (T2DM), but evidence in Chinese populations is limited. We investigated the relationship between coffee consumption and T2DM in a population-based cohort of middle-aged Chinese. ⋯ Coffee intake is inversely associated with T2DM in Chinese. Coffee may be a protective agent for T2DM in Chinese.
