In contrast to leptin, serum concentrations of ghrelin are not related to premenstrual syndrome.

چکیده
OBJECTIVE Premenstrual syndrome (PMS) is a disorder related to mood and appetite changes during the premenstrual phase. Unfortunately, the understanding of the pathophysiology of PMS is quite poor. Though, ghrelin and leptin play important roles in the control of food intake. The aim of this study was to evaluate leptin and ghrelin serum concentrations in PMS patients. PATIENTS AND METHODS Forty-five PMS patients diagnosed according to ICD-10 diagnostic criteria and 45 healthy women as a control group, were included in the study. These groups were matched for age, body mass index and duration of menstrual cycle. Symptoms of the patients were evaluated using "Menstrual Distress Questionnaires". Serum leptin and ghrelin serum concentrations were measured using ELISA in the postmenstrual phase (5-9 days) and 2-3 days before menstruation. Mann-Whitney U test, independent sample t-test and Wilcoxon test were used for statistical analyses. RESULTS In the PMS group, there was no difference in the serum concentrations of ghrelin; however, leptin serum concentrations were 31.05 (± 14.16) and 16.42 (± 15.81) ng/ml during the premenstrual and postmenstrual periods, respectively (p < 0.05). Ghrelin serum concentrations in the premenstrual period were 6.9 (± 9.3) ng/ml in the PMS group and 8.8 (± 9.3) ng/ml in the control group, but this difference was not statistically significant (p = 0.79). CONCLUSIONS Ghrelin serum concentrations were not associated with PMS, while leptin serum concentrations were found to be higher in the premenstrual period in PMS patients. Though, these two hormones work antagonistically to control the food intake and body weight, we suggest that this function is not relevant to PMS.

Relationship between Serum Leptin, Ghrelin and Dietary Macronutrients in Women with Polycystic Ovary Syndrome
Background Polycystic ovary syndrome (PCOS) is the most common endocrinopathy in women. It may involve an impairment in physiologic regulation of leptin and ghrelin. There is limited, controversial data on the relation of dietary components with leptin and ghrelin in PCOS, so the current study has been conducted to explore the effects of different macronutrients on serum levels of leptin and gh...

The relationship between leptin, adiponectin, ghrelin, homocysteine, insulin resistance and other biochemical factors in women with polycystic ovary syndrome (PCOS) is controversial. We review how the expanded role of these factors in reproduction might impact our understanding of PCOS. For purposes of our review, we accessed the PUBMED database during the past 10 years. Our review confirms tha...

Evaluation of Ghrelin and Leptin in Patients with Thyroid Malfunction
Introduction: Leptin and Ghrelin are hormones that have been discovered in the last decade and were shown to be involved in appetite and metabolism regulation and body weight. Thyroid hormones are also involved in general metabolism and changes in their circulating levels bring about changes in appetite and body weight. Results of animal and human studies regarding Leptinlevel and its re...
