Association Between Irisin, Inflammatory Markers and Metabolic Status in Obese Children With Type 2 Diabetes Mellitus

Mexican children and adolescents previously diagnosed with type 2 diabetes mellitus according to the American Diabetes Association (ADA) criteria were recruited and compared to healthy controls. The participants will undergo: * vital signs measurement (systolic and diastolic blood pressure, heart rate, respiratory rate) * anthropometric variables measurement (BMI, weight, waist circumference, hip circumference, body fat %) * laboratory studies: glucose, triglycerides, HDL-c, C reactive protein, irisin After statistical analyses the investigators will compare the relationship of irisin and the inflammatory profile and the anthropometric parameters of diabetic patients versus lean controls.
