Objectives: To evaluate leptin and adiponectin as markers of undernutrition in cancer patients, and compare their performances with those of other biomarkers.
Design And Methods: This was a prospective and observational study of 132 patients with various types of cancer. Following the recommended professional criteria, we diagnosed undernutrition at the time of blood sampling for the biological analysis of leptin, adiponectin, paraoxonase (hydrolysis rate of three substrates: paraoxon (PON), phenylacetate (ARE) and thiolactone (LAC)), and the calculation of the Prognostic Inflammatory and Nutritional Index (PINI).
Attachment to carbohydrates of the histo-blood group type of several human Rotavirus strains (RVA) has recently been described. Synthesis of these ligands requires a functional FUT2 enzyme, suggesting that FUT2 null homozygote (ie, nonsecretor) individuals may not be recognized by most human RVA strains. Whereas such individuals represent 20% of the control population, this retrospective study determined that none of 51 patients infected by P[8] rotavirus strains were nonsecretors.
