Megjegyzések:	Background: Obestatin is a ghrelin-associated peptide, derived from preproghrelin. Although many of its effects are unclear, accumulating evidence supports positive actions on both metabolism and cardiovascular function. To date, level of obestatin and its correlations to the lipid subfractions in non-diabetic obese (NDO) patients have not been investigated. Methods: Fifty NDO patients (BMI: 41.96?8.6 kg/m2) and thirty-two normal-weight, age- and gender-matched healthy controls (BMI: 24.16?3.3 kg/m2) were enrolled into our study. Obestatin level was measured by ELISA. Low-density lipoprotein (LDL) and high-density lipoprotein (HDL) subfractions, intermediate density lipoprotein (IDL) and very low-density lipoprotein (VLDL) levels and mean LDL size were detected by nongradient polyacrylamide gel electrophoresis (Lipoprint).Results: Serum level of obestatin was significantly lower in NDO patients compared to controls (3.01?0.5 vs. 3.29?0.6 ?g/ml, p<0.05). We found significant negative correlations between the level of obestatin and BMI (r=-0.33; p<0.001), level of serum glucose (r=-0.27, p<0.05), HbA1c (r=-0.38; p<0.001) and insulin (r=-0.34; p<0.05). Significant positive correlation was found between obestatin level and the levels of ApoA1 (r=0.25; p<0.05), large HDL subfraction ratio and level (r=0.23; p<0.05 and r=0.24; p<0.05), IDL (r=0.25 p<0.05) and mean LDL size (r=0.25; p<0.05). Serum VLDL ratio and level negatively correlated with obestatin (r=-0.32; p<0.01 and r=-0.21; p=0.05). In multiple regression analysis obestatin was predicted only by VLDL level.Conclusions: Based on our data, measurement of obestatin level in obesity may contribute to understand the interplay between gastrointestinal hormone secretion and metabolic alterations in obesity.

Cím:	Impact of selective LDL apheresis on serum chemerin levels in patients with hypercholesterolemia / Viktória E. Varga, Hajnalka Lőrincz, Noémi Zsíros, Péter Fülöp, Ildikó Seres, György Paragh, József Balla, Mariann Harangi
Dátum:	2016
Megjegyzések:	Background: Selective low-density lipoprotein (LDL) apheresis is commonly used to treat patients with familialhypercholesterolemia (FH). Chemerin is an adipokine with putative roles in the regulation of lipid metabolism.Methods: In our pilot study, we measured serum chemerin levels by enzyme-linked immunosorbent assay in sixsevere heterozygous FH patients before and after their first LDL apheresis treatments using the technique of directadsorption of lipoproteins (DALI).Results: The first treatment sessions decreased serum chemerin levels by an average of 27.26 %. While followingone patient, 12 months of regular LDL apheresis resulted in a permanent reduction in his serum chemerin level.Changes in the lipoprotein subfractions measured by gel electrophoresis (Lipoprint) correlated with the reductionof chemerin levels. Furthermore, we eluted and then measured chemerin bound to the DALI column.Conclusion: We conclude that LDL apheresis decreases the circulating level of chemerin by binding the protein tothe column and thus improves lipoprotein subfraction pattern.
