Objective: We intend to assess the utility of the high-sensitivity C-reactive protein (hs-CRP) as a marker of cardiovascular risk in obese children and adolescents. Methods: The study included children and adolescents between 6 and 18 years of age with a body mass index (BMI) higher than 2 SDS. All the patients had their blood pressure taken and hs-CRP, hepatic function, lipid profile and uric acid were determined after 12 h of fasting. Likewise, an oral glucose tolerance test was performed, determining basal glucose and insulin levels, and after stimulus. We considered the presence of metabolic syndrome when the obese children and teenagers showed at least two of the following conditions: decreased high density lipoprotein (HDL)-cholesterol, hypertriglyceridemia, hypertension or alteration in glucose metabolism. Results: Out of the 115 obese children studied, 24% showed signs of metabolic syndrome. Those with metabolic syndrome presented higher levels of hs-CRP (mean: 3.8 mg/l; 95% CI: 2.8-4.8) in comparison with the obese patients who did not show signs of metabolic syndrome (mean: 2 mg/l; 95% CI: 1.5-2.5). After a multivariate analysis, the variables that appear to influence the changes in hs-CRP were BMI, triglycerides and HDL-cholesterol levels. Conclusion: The hs-CRP is a useful tool for early diagnosis of cardiovascular risk in obese children and teenagers.European Journal of Endocrinology 159 R1-R4

Severe hypernatraemia is described as a rare cause of rhabdomyolysis and renal failure. In critically ill patients, it is important to have a high index of suspicion for rhabdomyolysis and performing serial determinations of creatine phosphokinase for early detection and treatment.
