        Plasma Apelin, Visfatin and Resistin Levels in Patients with First Episode Psychosis and Chronic Schizophrenia

        Musa Sahpolat,Mustafa Ari,Mehmet Hanifi Kokacya 대한정신약물학회 2020 CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE Vol.18 No.1

        Objective: This study aims to investigate the possible relationship between plasma concentrations of apelin, visfatin and resistin levels of first episode psychosis patients and chronic schizophrenia patients. Methods: A total number of 29 untreated patients with first episode psychosis, 30 chronic schizophrenia and 29 randomly selected weight- and body mass index-matched healthy volunteers were included. The Diagnostic and Statistical Manual of Mental Disorders 4th edition, Positive and Negative Syndrome Scale (PANSS) and Clinical Global Impression Scale were applied to the patient groups. The enzyme-linked immunosorbent assay method was used to measure plasma apelin, visfatin and resistin levels. Results: There was no difference in age, marital status, occupation, and BMI between the groups. Plasma apelin levels were significantly higher in first episode psychosis group than chronic schizophrenia and control group. There was no statistically significant difference in plasma visfatin levels between the groups: first episode psychosis group, chronic schizophrenia and control group. Plasma resistin levels were higher in both first episode psychosis group and chronic schizophrenia group than the control group. There was no statistically significant correlation between plasma apelin and resistin levels and total PANSS scores in the group of patients. Conclusion: To our knowledge, this study is the first which investigates the plasma apelin, visfatin and resistin levels in patients with first episode psychosis and chronic schizophrenia. Based on the results of this study, apelin and resistin may be related with some central nervous system pathologies, including the severity of a psychiatric disorder.

        Elevated Monocyte to High-density Lipoprotein Ratios as an Inflammation Markers for Schizophrenia Patients

        Musa Sahpolat,Duygu Ayar,Mustafa Ari,Mehmet Akif Karaman 대한정신약물학회 2021 CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE Vol.19 No.1

        Objective: Monocyte to high density lipoprotein ratio (MHR) is a new instrument for giving notice inflammation, which plays a main role in schizophrenia. Thus, in this study, our goal was to investigate the possible association between MHR and schizophrenia. Methods: The participants of this study consisted of 75 schizophrenia patients and 74 healthy individuals (control group). The Positive and Negative Syndrome Scale was used to collect data from the patient group. Complete blood count parameters and lipid profile were analyzed in all study participants. Results: The patients with schizophrenia had higher MHR values (15.04 ± 3.31 in schizophrenia patients and 12.62 ± 2.99 in controls; p = 0.001). Monocyte counts and MHR of the schizophrenia patients were significantly higher than the control group. There was a significant and positive correlation between age, body mass index, severity of disease and MHR. Conclusion: To our knowledge, this study was the first to demonstrate inflammatory markers such as MHR levels in schizophrenia patients. Both monocyte counts and MHR values in schizophrenia patients were higher than the control group. MHR might be an available and useful inflammatory marker to evaluate inflammation in schizophrenia patients.

        The association of reproductive hormones, thyroid function, and vitamin levels with premature ejaculation: A prospective case-control study

        Yasar Pazır,Haydar Guler,Taha Burak Bulut,Emre Ari,Semih Aktas,Mustafa Kadıhasanoglu 대한비뇨의학회 2024 Investigative and Clinical Urology Vol.65 No.2

        Purpose: To investigate whether serum hormone (testosterone, prolactin, gonadotropins, and thyroid hormones) and vitamin (vitamin B12, folic acid, and vitamin D) levels are associated with premature ejaculation (PE). Materials and Methods: This prospective case-control study included 126 patients with PE (lifelong PE [LPE] in 94 and acquired PE [APE] in 32) who presented to the urology outpatient clinic between April 2016 and January 2023 and 92 healthy men as a control group. The diagnosis of PE was based on the criteria defined by the International Society for Sexual Medicine. Serum total testosterone (TT), free and bioavailable testosterone, follicle-stimulating hormone, luteinizing hormone, prolactin, thyroid-stimulating hormone, free triiodothyronine, thyroxine (fT4), vitamin B12, folic acid, and vitamin D levels were measured. Results: Serum TT, fT4, and vitamin D levels were significantly higher in patients with PE than in the control group (p=0.022, p=0.002, and p=0.044, respectively). However, the serum vitamin B12 level was significantly lower in the PE group (p=0.021). In the multivariate logistic regression analysis, only vitamin B12 was found to be an independent risk factor for PE, with an estimated odds ratio of 0.997 (95% confidence interval 0.994–0.999, p=0.036). Conclusions: This study demonstrated that lower vitamin B12 levels are associated with the presence of PE. Therefore, we believe that it would be beneficial to consider vitamin B12 levels in the evaluation of patients with PE.
