BONNEAU, Graciela A et al. Insulin resistance and its relationship with adiponectin in posadas-misiones hospital staff. Rev. cienc. tecnol. [online]. 2013, n.19, pp.77-82. ISSN 1851-7587.

The initial disturbance of insulin resistance appears to focus on adipose tissue, which is a dynamic organ involved in many physiological and metabolic processes. It expresses and secretes a variety of active peptides, adipocytokines. The aim of this study was to determine the prevalence of insulin resistance and its relationship with circulating adiponectin as a marker of adipose tissue metabolism in an urban population represented by staff member from two public hospitals in Posadas, Misiones. We evaluated the 176 employees of two public hospitals in Posadas, Misiones, 117 women and 59 men, aged 49.01 ± 9.33 years. Individuals with diabetes, hypothyroidism or hyperthyroidism, infectious disease, renal or hepatic neoplasms and pregnant women were excluded. A blood sample with 8 hrs. fasting was carried out. Blood glucose: enzymatic colorimetric method according to Trinder. Insulin was determined by a chemiluminescent immunometric assay on a solid phase 2000-.Siemmens Immulite. Adiponectin was detected with monoclonal antibodies (ALPCO immunoassays). All samples were processed with calipers, normal and pathological commercial and internal and external quality controls. Epi Info 6.04d was used for data analysis. The frequency of insulin resistance found in the population studied was 17.2% and 45.7% with decreased concentrations of adiponectin. We found a highly significant association of serum adiponectin with insulin resistance (p <0.001) which also independently predicts the event in women (p <0.001). In our public hospital staff population one in five individuals presents insulin resistance. Adiponectin could independently explain it, only in women.
