title: [Correlations between endogenous intoxication and excessive body weight].
abstract: The aim of the study was to analyze correlations between endogenous intoxication (EI) and lipid peroxidation (LP) indices in patients with cardiovascular and endocrine diseases and healthy individuals, taking into account the presence of excessive body weight (EBW), as well as to compare EI and LP indices in practically healthy people with and without excessive body weight (EBW). The subjects were 165 people, including 36 healthy individuals and 129 patients with cardiovascular and endocrine disease. The healthy ones were divided into two groups: 20 with and 16 without EBW. To evaluate the degree of EI, the concentration of middle-molecular-weight peptides (MMWP) was measured by the method offered by N. I. Gabrielyan et al. in 1984. To evaluate LP processes, serum levels of the secondary LP product, malonic dialdehyde, and two antioxidative enzymes, superoxide dismutase and catalase, were measured. The results show that treatment aimed at LP suppression is not appropriate; it should be aimed at the cause of LP activation instead, which is the increase of MMWP level due to EBW. LP activation significantly correlates with increase of MMWP blood level (p < 0.05). EBW worsens EI and activates LP in healthy people, thus being a stress factor to the organism. Increased MMWP level and LP activation in healthy individuals with EBW may be a premorbid diagnostic marker.
