    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.

    The relationship between serum irisin levels and erectile dysfunction in diabetic men (irisin and erectile dysfunction in diabetic patients)
    (2021) Kumsar, Sukru; Cigerli, Ozlem; Hasirci, Eray; Akay, Ali F.; Peskircioglu, Levent; https://orcid.org/0000-0003-3700-4104; https://orcid.org/0000-0002-4147-2966; https://orcid.org/0000-0003-0389-9472; 33400308; AAD-5584-2021; AAI-7997-2021; S-4494-2019
    Irisin is an exercise-induced myokine that alleviates endothelial dysfunction and reduces insulin resistance in type 2 diabetes mellitus. We conducted this cross-sectional prospective study to determine the association of serum irisin levels and erectile dysfunction in type 2 diabetic patients. We compared 34 diabetic patients with erectile dysfunction with 30 diabetic patients without erectile dysfunction. In our study, serum irisin levels were found to be statistically significantly higher in diabetic patients without erectile dysfunction compared to those with erectile dysfunction (p = .016) and according to correlation analysis, irisin levels had a significantly negative correlation with the serum HbA1C value (r = -.294, p = .018). Based on the results of our study, we think that this molecule can be used in the diagnosis or treatment of erectile dysfunction in diabetic patients, if these findings are supported by larger studies.
