Suppressive effect of hyperinsulinemia on serum interleukin 18 concentration in young healthy subjects

Straczkowski M. , Karczewska-Kupczewska M. , Adamska A. , Nikolajuk A. , Matulewicz N. , Zielinska M. , Gorska M. , Kowalska I.

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 ...

Plasma anti-Müllerian hormone concentration in women with polycystic ovary syndrome and type 1 diabetes mellitus

Lebkowska A. , Karczewska-Kupczewska M. , Nikolajuk A. , Adamska A. , Otziomek E. , Wolczynski S. , Gorska M. , Kowalska I.

Introduction: A high prevalence of polycystic ovary syndrome (PCOS) and hyperandrogenism has been described in adult women with type 1 diabetes mellitus (T1DM). Anti-Müllerian hormone (AMH) is secreted by granulosa cells of antral ovarian follicles and its plasma concentration is correlated with the number of small antral follicles. AMH levels are increased in women with PCOS and higher plasma concentration has been observed in prepubertal girls with T1DM. The aim of this...

Circulating interleukin 6 and soluble forms of interleukin 6 receptor and glycoprotein 130 in women with anorexia nervosa

Karczewska-Kupczewska M. , Kowalska I. , Nikolajuk A. , Adamska A. , Otziomek E. , Gorska M. , Straczkowski M.

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...

Plasma interleukin 18 in patients with polycystic ovary syndrome – relation to insulin resistance

Kowalska I , Straczkowski M , Nikolajuk A , Kozlowska A , Karczewska-Kupczewska M , Adamska A , Wolczynski S , Kinalska I , Gorska M

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...

Serum visfatin is differentially regulated by insulin and non-esterified fatty acids in healthy men

Kowalska I , Karczewska-Kupczewska M , Adamska A , Nikolajuk A , Kaminska N , Zielinska M , Otziomek E , Gorska M , Straczkowski M

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...
