[Weight reduction and aspects of the metabolic syndrome].
We carried out analysis of the influence of long-term weight reduction on individual parameters of metabolic syndrome X. We enrolled the total of 30 obese patients (22 with, 8 without syndrome X). During weight reduction, the mean BMI decreased by 4.08 +/- 3.00 kg/m2 leading to significant (p < 0.001) decrease in insulinaemia from 33.4 +/- 25.9 to 21.2 +/- 19.625 mu j/ml. In patients with syndrome X, the decrease in BMI of 3.50 +/- 2.76 kg/m2 was coupled with significant (p < 0.001) decrease in insulinaemia from 39.7 +/- 27.7 to 24.0 +/- 21.725 mu j/ml. Using cluster analysis of cases syndrome X patients formed two distinctive groups with different behaviour. It seems, that diagnosis of metabolic syndrome, based on arbitrary criteria, encompasses stable patients, in our study characterized by higher age and presence of hypertension, and volatile patients, who form somewhat transition stage between simple obesity and fully developed syndrome X. Moreover, relationships between individual parameters at the beginning of the study can elucidate the environmental influences (relationship between insulinaemia and hypertension), whereas those at the end of the study represent true pathogenetic relationships (insulinaemia and glycaemia) and relationships between syndrome X constituents (hypertension, hypertriglyceridaemia and decrease in HDL cholesterol).
