Establishment of a cut-point value of serum TNF-α levels in the metabolic syndrome

Cardiovascular diseases and type 2 diabetes are the major causes of mortality in Mexico. Metabolic syndrome (MS) is a cluster of factors that increase the risk to develop such diseases. Previous studies have shown that MS is associated with high tumor necrosis factor (TNF-α) levels. In fact, TNF-α has been proposed to be a useful marker for clinical diagnosis of inflammation at an early stage. Therefore, we analyzed TNF-α concentrations in Mexican individuals with or without MS and related these levels to the associated MS components. Clinical, anthropometric, and biochemical data were analyzed in 41 healthy and 39 MS individuals. Individuals were similarly grouped by age and gender. The serum TNF-α levels measured by a highly sensitive enzyme-linked immunosorbent assay (ELISA) kit were increased significantly in MS subjects compared with healthy individuals (P<0.001). The assay showed 78.1% sensitivity and 61.5% specificity with a cut-point level of 1.36pg/mL. TNF-α levels higher than the cut-point value were correlated with insulin resistance indices. These findings support the hypothesis that serum TNF-α concentration could be a useful marker for early MS diagnosis. Nevertheless, we suggest the establishment of specific cut-point values in each studied population to evaluate potential clinical applications. © 2009 Wiley-Liss, Inc

A controlled clinical trial with pirfenidone in the treatment of pathological skin scarring caused by burns in pediatric patients

Background: The uncarboxylated osteocalcin (ucOC) has been described as a regulator of glucose metabolism in mice, and it is decreased in human type 2 diabetes mellitus (T2D). Although inversely correlated with serum glucose, insulin, and glycated hemoglobin, it is unclear if ucOC decrement is caused by diabetes or plays a role in the pathogen-esis and/or progression of the disease. Whatever the case may be, diabetes affects osteoblast gene expression, and possibly the proportion of ucOC over carboxylated OC (cOC). The association of ucOC/cOC index with glycemic status markers in patients with T2D has not been described before. Objective: The objective of this study was to assess the ucOC/cOC index and its relationship with glycemic status markers in patients with T2D. Methods: The ucOC/cOC index was determined by the quotient of ucOC and cOC serum levels in 80 T2D patients and 160 healthy subjects. The relationship between the ucOC/cOC index and glycemic status markers was evaluated. Results: The ucOC/cOC index was low and negatively correlated to fasting plasma glucose and homeostasis assessment-insulin resistance model in T2D patients. The odds ratio for T2D patients with an ucOC/cOC index below the cut-point obtained by receiver operating characteristic analysis was 12.64 (confidence interval, 5.75-27.77; P < 0.001). Conclusions: A value of ucOC/cOC index less than 0.3 is associated with markers of poor metabolic control in patients with T2D.

Stress neuropeptide levels in adults with chest pain due to coronary artery disease: potential implications for clinical assessment

: Substance P (SP) and neuropeptide Y (NPY) are neuropeptides involved in nociception. The study of biochemical markers of pain in communicating critically ill coronary patients may provide insight for pain assessment and management in critical care. Purpose of the study was to to explore potential associations between plasma neuropeptide levels and reported pain intensity in coronary critical care adults, in order to test the reliability of SP measurements for objective pain assessment in critical care
