Resistin is still a little known hormone of the adipose tissue. The potential role of resistin in the development of DM2 has been currently investigated. The aim of our study was to detect the resistin blood level in patients with DM2, depending on the duration of the disease. In so doing, a determination of resistin and insulin blood level was conducted in 305 patients with DM2, and in a control group of 32 persons. Before testing, the patients were placed into four groups, depending on the duration of type 2 diabetes. Our results indicate that the resistin level was significantly lower in the control group of patients, in comparison with the DM2 patients groups. Moreover, a significantly lower resistin level was found in group I (firstly diagnosed DM2), in comparison with the groups of patients with a different duration of DM2. No correlation between resistin level and BMI, and between resistin and insulin blood level was found. However, a tendency towards increase of resistin blood level is noticeably evident in co-relation with increment of DM2 duration. In addition, the resistin level was considerably lower in patients with no DM2, when compared with patients with diagnosed DM2. Yet, there was no significant difference in the resistin blood level depending on the sex of the patients at the same duration of DM2

Bariatric surgery is the most effective method to achieve weight loss in obese subjects. The aim of this study was to evaluate some adipocytokines and insulin, as well as parameters of metabolic syndrome of the obese patients, for three and six months after vertical banded gastroplasty, in the time of dynamic weight loss. Seven males and two females aged 28 to 49 years, with long lasting simple obesity and the presence of metabolic syndrome, were studied. After surgical treatment the values of the body mass index, waist circumference, systolic and diastolic blood pressure, total cholesterol, LDL cholesterol, triglycerides, and blood concentrations of leptin decreased significantly. Before surgical operation of all obese patients no statistically significant correlations between studied parameters were noted. Three and six months later a lot of correlations between studied parameters appeared. In conclusion, (a) vertical-banded gastroplasty is a valuable method in treatment of obese subjects, leading to a significant decrease in body weight and improvement in some parameters of metabolic syndrome in a few months after surgery, (b) adipocytokines, together with an unknown gastric factor, may be key factors in the control of some features of the metabolic syndrome.

The aim of this study was to analyze the effects of sports training on the physiological response to supra-maximal exercise during consecutive phases of the annual training cycle. The study was carried out in volleyball players at the onset of each training phase. VO2 max was determined by an indirect method using the Ästand-Rhyming nomogram and biochemical analyses were performed before and after the Wingate test. Concentrations of lactate in capillary blood were measured and levels of glucose, insulin, visfatin, resistin, thiobarbituric acid reactive substances (TBARS) of serum and the total antioxidative status of plasma were determined using venous blood.Most significant differences with respect to physiological and biochemical variables centered around the pre-competitive phase when compared to other phases of the annual training cycle. Blood visfatin concentration in highly trained volleyball players is reduced by supra-maximal exercise, whereas levels of resistin remain relatively constant at rest. With the exception of the competitive phase, values of the insulin resistance index fit within the reference range. Levels of lipid peroxidation products were inversely correlated with the insulin resistance index and resistin concentrations.The physical training during the annual cycle does not affect resistin levels, but influences insulin, glucose and visfatin concentrations, along with markers of pro-oxidant/antioxidant balance in beach volleyball players.

This study investigated associations between the growth hormone/insulin-like growth factor-1 (GH/IGF-1) axis, adiponectin, resistin and metabolic profile in 47 GH-deficient children before and during 12 months of GH treatment. 23 short age-matched children without growth hormone deficiency (GHD) or any genetic or chronic disorders were recruited as controls at baseline. Metabolic evaluation included measurements of adiponectin, resistin, IGF-1, total cholesterol (total-C), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), glucose, insulin, glycated haemoglobin (HbA1c), thyroid stimulating hormone (TSH) and free thyroxine (free T4) concentrations. The GH-deficient children had significantly higher adiponectin (p<0.05) and total cholesterol (p<0.05) levels, and a significantly lower level of resistin (p<0.05) than the controls. Resistin at 6 months of GH treatment significantly correlated with changes in height SDS in that period (r=0.35) and with the level of fasting insulin (r=0.50), the HOMA-IR (r=0.56) and the QUICKI (r=-0.53) at 12 months of therapy. Adiponectin level at 12 months of GH treatment was significantly associated with changes in HDL-C within the first 6 (r=0.73) and within 12 (r=0.56) months of therapy, while resistin significantly correlated with an increment in IGF-1 within 12 months of treatment (r=0.49) and with total-C at 12 months (r=0.56). Untreated GH-deficient children had higher adiponectin and lower resistin levels than healthy short children without GHD. Adiponectin and resistin levels did not change significantly during the first 12 months of GH therapy. Good responders to GH treatment had a tendency for higher resistin level during GH therapy, which positively correlates with the insulin resistance parameters.
