Influência da adiposidade global e da adiposidade abdominal nos níveis de proteína C-reativa em mulheres idosas

Metabolic syndrome and C-reactive protein in bank employees

BACKGROUND

The ultrasensitive C-reactive protein (us-CRP) is used for the diagnosis of cardiovascular disease, but it is not well described as a marker for the diagnosis of metabolic syndrome (MS).

METHODS

An observational and transversal study of bank employees evaluated anthropometric, hemodynamic, and biochemical data. CRP values were determined using commercial kits from Roche Diagnostics Ltd, and MS criteria were analyzed according to National Cholesterol Education Program's - Adult Treatment Panel III (NCEP/ATP III).

RESULTS

A total of 88 individuals had MS, and 77.3% (n=68) of these showed alterations of us-CRP (P=0.0001, confidence interval [CI] 0.11-0.34). Individuals with MS had higher mean values of us-CRP in global measures (P=0.0001) and stratified by sex (P=0.004) than individuals without the syndrome. This marker exhibited significant differences with varying criteria for MS, such as waist circumference (P=0.0001), triglycerides (P=0.002), and diastolic blood pressure (P=0.007), and the highest levels of us-CRP were found in individuals with more MS criteria.

CONCLUSION

us-CRP was strongly associated with the presence of MS and MS criteria in this group of workers. us-CRP is a useful and effective marker for identifying the development of MS and may be used as a reference in routine care.

Comparison of Inflammatory, Metabolic, and Anthropometric Parameters in Elderly Women With and Without Insulin Resistance

The objective of the present study was to investigate the relationship between inflammatory, metabolic, and anthropometrical parameters of elderly women with insulin resistance (IR) and without insulin resistance (WIR). One hundred and seventy-two elderly women aged 67.5 (± 5 years) were submitted to anthropometrical analysis, by dual energy X-ray absorptiometry, and biochemistry tests such as lipidogram, fasting blood glucose, glycosylated hemoglobin, insulin, C-reactive protein, Interleukin-6, tumor necrosis factor-alpha, and Interferon-gamma. Body mass index, waist circumference, waist-to-hip ratio, body fat mass, triglycerides, very low density lipoprotein, fasting glucose, and insulin were significantly higher, while lean body mass was lower ( p < 0.05), in elderly with IR as compared to WIR. There was no significant difference between groups in the inflammatory parameters. Elderly women with IR present increased anthropometrical and metabolic parameters that predispose them to several chronic nontransmissible diseases. Additional inflammatory parameters should be used in elderly women to define an optimal relationship with insulin resistance in clinical practice.
