    Assessment of Irisin, Adiponectin and Leptin Levels in Patients with Schizophrenia
    (2018) Erzin, Gamze; Topcuoglu, Canan; Kotan, Vahap O.; Bayram, Senol; Fountoulakis, Kostas; 29219062
    Background: The patients with schizophrenia are at increased risk for problems regarding metabolic parameters due to their lifestyle and antipsychotic treatment. Objective: In this study, we aimed to evaluate the levels of adiponectin, leptin, irisin in patients with schizophrenia who were nondiabetic, nonobese and under antipsychotic treatment. Method: 5 ml sample of venous blood was collected from each participant. Blood cells were separated from the serum. The serum samples were stored in a -80 degrees C freezer. Biochemical analyses were performed on these samples. Adiponectin, leptin and irisin levels were measured by Enzyme Linked Immunosorbent Assay method. Results: The study included 88 subjects. Of them, 44 were patients with schizophrenia and 44 were healthy controls. There were no statistically significant results when the c-reactive protein, adiponectin, leptin and irisin levels were compared between the schizophrenia and the control group (p>0.05). Conclusion: In our study, adiponectin, leptin and irisin levels in patients with schizophrenia did not present a statistically significant difference from healthy controls. Therefore, there is a need for studies including more participants to investigate the level of irisin in patients with schizophrenia.

    Exogenous Recombinant Adiponectin Improves Survival in Experimental Abdominal Sepsis
    (2014) Salman, Bulent; Yilmaz, Tonguc Utku; Tezcaner, Tugan; Demir, Ebru fluoglu; Pasaoglu, Ozge Tugce; 25337421
    Background: Adiponectin, which has anti-inflammatory features, is an important substance in several metabolic mechanisms. Aims: The aim of this study is to evauate the effects of exogenous intraperitoneal administration of adiponectin on the survival, intrabdominal adhesion and inflammatory cytokine levels in an experimental sepsis model. Study Design: Animal experimentation. Methods: Ninety rats were divided into a control group, adiponectin group and sham group. A cecal puncture abdominal sepsis model was performed in the adiponectin and control groups. Every three hours, exogenous adiponectin was administrated to the adiponectin group. At the 3(rd) and 24(th) hours, 10 rats were sacrified in each group in order to measure plasma tumor necrosis factor-alpha (TNF-alpha), interleukin (IL) 10, soluble intracellular adhesion molecule (ICAM)-1, IL-6 and macrophage inhibitory factor levels, and the activity of nuclear factor (NF)-kappa B. The remaining rats were followed for survival. Results: The plasma levels of TNF-alpha, soluable ICAM-1, IL-6, and macrophage inhibitory factor were significantly higher in the control group than in the adiponectin and sham group (p<0.05). The increase in inflammatory cytokines with time was more prominent in the control group. The activity of NF-kappa B in the control group was higher than in the adiponectin group (p<0.05). The survival rate of the adiponectin group was higher than in the control group. Conclusion: Administration of exogenous adiponectin to the peritoneum in abdominal sepsis increased survival and decreased intrabdominal adhesions by decreasing the inflammatory response.
