AB  - This study examines the relationship between erythrocyte phospholipid FA composition and insulin sensitivity in obese patients on a typical Serbian diet. In 30 patients, two insulin sensitivity groups were formed and their FAs analyzed. The shares of 22:5n-3, 22:6n-3, and total n-3 PUFAs, as well as a measure of Delta 5 desaturase activity (the 20:4n-6/20:3n-6 ratio) were lower in the insulin resistance group compared to the normal glucose tolerance group. The fasting insulin level and HOMA value were inversely related to the percentage of 22:5n-3, 22:6n-3, and total n-3 PUFAs. Our data indicate that the percentage of n-3 PUFAs in erythrocyte phospholipids is linked with insulin sensitivity parameters in obese patients.
AB  - Masnokiselinski sastav membrana, koji se bar delimično može modifikovati dijetarnim unosom masnih kiselina, igra važnu ulogu u senzitivnosti na insulin. Cilj ove studije bio je ispitivanje veze između senzitivnosti na insulin i masnokiselinskog sastava fosfolipida eritrocita kod gojaznih osoba. Trideset umereno gojaznih/gojaznih nedijabetičara sa hiperlipoproteinemijama (ukupni holesterol  gt  5.2 mmol/l, LDL-holesterol  gt  3.4 mmol/l) podeljeni su u dve grupe, koristeći HOMA vrednost kao parametar senzitivnosti na insulin: grupu sa normalnom tolerancom na glukozu (NTG) i grupu sa rezistencijom na insulin (IR). Ukupni lipidi eritrocita su estrahovani i fosfolipidi izolovani tankoslojnom hromatografijom. Posle metilovanja masne kiseline analizirane su gasno-tečnom hromatografijom. Zastupljenost 22:5n-3 (p  lt  0.01), 22:6n-3 (p  lt  0.01), ukupnih n-3 polinezasićenih masnih kiselina (p  lt  0.001) i odnos zastupljenosti 20:4n-6/20:3n-6 (pokazatelja aktivnosti delta-5 desaturaze) (p  lt  0.05) su sniženi u IR grupi u poređenju sa NGT grupom. Nivo insulina natašte i HOMA vrednost inverntno su povezani sa zastupljenošću 22:5n-3 (p  lt  0.05), 22:6n-3 (p  lt  0.01) i ukupnim n-3 polinezasićenim kiselinama (p  lt  0.01). Naši rezultati pokazuju da je nivo n-3 masnih kiselina u fosfolipidima eritrocita povezan sa senzitivnošću na insulin kod gojaznih osoba na ishrani tipičnoj za podneblje Srbije.

AB  - Background Blood cholesterol levels are affected by diet and in particular by the type of fat intake. We originally showed that a significant but variable amount of cholesterol is firmly bound to haemoglobin (Hb) yielding the Hb-lipid adduct (Hb-Ch) in erythrocytes isolated from normo-lipidemic males. Aim of the study To establish whether dietary lipids affect the level of Hb-Ch in human erythrocytes. Methods Seventy-four healthy free-living adults were separated according to their serum cholesterol levels into two groups: normo-cholesterolemic (LDL cholesterol  lt  3.4 mmol/l and total cholesterol  lt  5.2 mmol/l) (NC) and hyper-cholesterolemic (LDL cholesterol  gt = 3.4 mmol/l) (HC). Habitual dietary information was used to classify subjects in both study groups into sub-groups of low-fat ( lt = 30% total energy as fat) and high-fat consumers ( gt  30% total energy as fat). The NC low-fat consumers were placed on a high-lipid (high-fat and high-cholesterol) diet whereas the HC subjects with high-fat intake were assigned to a low-lipid (low-fat and low-cholesterol) diet. Both types of dietary intervention were allowed to continue for 6 weeks. The main variable under scrutiny was the Hb-Ch concentration. Results In both study groups low-fat intake subjects had low levels of Hb-Ch (approx. 0.35 mmol/l RBC) compared with high-fat intake subjects (approx. 0.60 mmol/l RBC), and serum cholesterol was not correlated with Hb-Ch. The two dietary interventions produced substantial changes in the Hb-Ch level that paralleled variation in the serum cholesterol concentration. A high-lipid diet (35% fat, 15% saturated; 580 mg cholesterol) increased Hb-Ch (by approximately 47%, P  lt  0.001) in subjects with low Hb-Ch at onset, whereas a low-lipid diet (28% fat, 9% saturated; 280 mg cholesterol) decreased Hb-Ch (by approximately 40%, P  lt  0.001) in subjects with high Hb-Ch at onset. Conclusion High consumption of dietary lipids, including saturated fat and cholesterol, has an important influence on the level of Hb-Ch in human erythrocytes.
