    The effects of hyperinsulinemia on cochlear functions
    (2020) Koca, Arzu Or; Koca, Huseyin Samet; Anil, Cuneyd; 33402607
    Context: Hyperinsulinemia is the most common metabolic change associated with cochleovestibular diseases. Aim: We aimed to investigate the auditory functions in hyperinsulinemic individuals. Settings and Design: A total of 164 patients were included in this case-control study. While 76 patients with insulin resistance (homeostasis model assessment of insulin resistance [HOMA-IR] of >= 2.5) constituted the case group, 88 patients with HOMA-IR values of <2.5 constituted the control group of the study. Material and Methods: The 75 g oral glucose tolerance test, blood biochemistry tests, hormonal analysis, audiological assessment, electrocochleography (EcochG), and transient evoked otoacoustic emissions (TEOAE) testing were performed. Statistical Analysis: One-way analysis of variance and Kruskal-Wallis analysis of variance were used for the comparison of the metabolic and ear parameters in the normal glucose tolerance (NGT), impaired fasting glucose (IFG), and impaired glucose tolerance (IGT) groups. The chi-square test was used to compare nominal variables. Spearman and Pearson correlation coefficients were used for the correlation analyses of continuous variables. Results: The pure tone audiometry at 0.5, 1, 2, and 4 kHz was better in the case group than in the control group. A positive correlation was found between HbA1c and right ear 0.5, 1, 4, and 8 kHz threshold values and left ear 2, 4, 6, and 8 kHz threshold values. A negative correlation was found between HbA1c and speech discrimination scores. The right ear 1.00 and 2.83 kHz TEOAE measurements in the individuals with NGT were found higher than those in patients with IGT, and the 1.42 kHz TEOAE measurements and reproducibility were found higher than those in patients with IFG. The left ear 1.00 and 1.42 kHz TEOAE measurements of the IGT patients were found lower than those of IFG and NGT patients. Conclusion: We showed that hearing was worsening in hyperinsulinemic patients and prediabetic conditions were related to hearing function impairment.

    Effect of weight loss diets on biochemical parameters and anthropometric measurements in prolactinoma patients
    (2019) Yesil, Esen; Kiziltan, Gul; Anil, Cuneyd; Ok, Mehtap Akcil; Bayraktar, Nilufer; AAZ-8170-2020
    Background: The aims of this study were to determine the effect of weight loss on biochemical parameters and anthropometric measurements in prolactinoma patients and to evaluate the effectiveness of weight loss diet along with medical treatment. Methods: Twenty-two patients with prolactinoma were divided into two groups and one of the groups was applied weight loss diet (diet group) while the other group was diet free (control group). Each participant was interviewed using a structured questionnaire. The biochemical parameters (fasting plasma glucose, fasting plasma insulin, prolactin, leptin, TSH, T4, cortisol, HbA1c, AST, ALT and blood lipids) of participants were analyzed and anthropometric measurements were taken. Results: There was a significant change in mean BMI after treatment in diet group (p=0.000). The mean level of serum prolactin decreased from 45.1 +/- 31.63 ng/dL at baseline to 12.6 +/- 8.19 ng/dL after three months in diet group (p=0.006). Despite there being no statistically significant difference between diet and control group in terms of baseline level of prolactin measurement (p=0.800), statistically significant difference between the two groups in terms of final level of prolactin measurement (p=0.027) was observed. There was a significant change in mean level of leptin after treatment in diet group (p=0.001). Conclusions: In addition to medical treatment, weight loss diets sped up the healing process for hyperprolactinemia and the reduction in body weight had positive effects on the metabolic profiles of prolactinoma patients.
