Introduction: Anorexia nervosa (AN) is an eating disorder, resulting in sustained low weight and marked decrease in fat mass. Interleukin 6 (IL-6) may play a role in appetite, energy expenditure and body weight control in central nervous system. IL-6 acts through binding with membrane receptor (IL-6R) and activates glycoprotein 130 (gp130) signaling. Both IL-6R and gp130 are present in the blood in the soluble forms (sIL-6R and sgp130, respectively). sIL-6R sensitizes cells to...

Introduction: Visfatin is a protein secreted by adipose tissue which was discovered as a protein with insulin-mimetic properties. Experimental and clinical studies demonstrated that visfatin can be involved in the pathogenesis of insulin resistance. It was demonstrated that plasma visfatin is elevated in insulin resistant states i.e. obesity, type two diabetes mellitus, PCOS. In vitro study showed that insulin inhibits visfatin release from adipocytes. The aim of the pr...

Introduction: Interleukin 18 (IL-18) is a proinflammatory and proatherogenic cytokine which is associated with obesity, insulin resistance and cardiovascular disease. It is supposed that insulin has anti-inflammatory action. The aim of the present study was to estimate serum IL-18 concentration in young healthy population, its regulation by hyperinsulinemia and relationship with insulin sensitivity and glucose and lipid oxidation.Methods: We studied 36 h...

Introduction: Numerous studies indicate an association between low-grade chronic inflammation and predisposition to type 2 diabetes and atherosclerosis. IL12 is a proinflammatory cytokine with proatherogenic properties. IL12 is a disulfide-linked, 70 kDa (p70) heterodimeric glycoprotein composed of a 40 kDa (p40) subunit and a 35 kDa (p35) subunit. Many data reported higher levels of p40 subunit than total IL12. The aim of the present study was to investigate the influence of ...

Aim of the study: Polycystic ovary syndrome (PCOS) is common disease affecting women in reproductive age which leads to anovulation. In pathogenesis of PCOS insulin resistance plays an important role. The aim of the present study was to look for possible relationship between interleukin 18 (IL-18) and insulin resistance in patients with PCOS.Material and Methods: The study was done in 76 patients with PCOS and 40 women without menstrual disturbances. The...
