Relationship between Serum Leptin, Ghrelin and Dietary Macronutrients in Women with Polycystic Ovary Syndrome

چکیده
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 ghrelin in PCOS and healthy subjects. MATERIALS AND METHODS In this case-control study, we randomly choose 30 PCOS pa- tients and 30 healthy age and body mass index (BMI) matched controls. Intake of macronutrients [protein, total fat, saturated, monounsaturated and polyunsaturated fatty acids (PUFA), carbohydrate, dietary fiber] and energy were assessed using 3-day, 24-hour food recall and food frequency questionnaires (FFQ). Fasting hormonal status was measured for each participant. RESULTS PCOS women had higher levels of serum leptin, insulin, testosterone, and luteinizing hormone (LH), whereas sex hormone-binding globulin (SHBG) was lower compared to healthy women. There was no significant difference in mean ghrelin concentrations between the groups. Among PCOS women, independent of BMI and total energy intake, we observed an inverse association between leptin concentration and total dietary fat (β=-0.16, P<0.05) and saturated fatty acid (SFA) intake (β=-0.58, P<0.05). This relationship was not seen in the healthy subjects. There was no significant association between ghrelin and macronutrients in PCOS and healthy participants. CONCLUSION Certain habitual dietary components such as fat and SFA may decrease serum leptin, whereas ghrelin is not influenced by these in PCOS women. More studies are needed to better clarify the effects of dietary macronutrients on serum leptin and ghrelin.

Leptin, Ghrelin, Adiponectin, Homocysteine and Insulin Resistance Related to Polycystic Ovary Syndrome
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...

Background: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in reproductive age women. The prevalence of PCOS among Iranian women is 14.6% based on the Rotterdam definition. PCOS can increase the risk of chronic metabolic complications. Metabolic syndrome (MetS) is one of the most important of them. Insulin resistance is fundamental in PCOS and MetS pathophysiology. MetS ...

BACKGROUND Polycystic ovary syndrome (PCOS) patients are more prone to abnormal production of some regulatory peptides. In these patients, studies on the serum levels of leptin and ghrelin are controversial. This study aims to investigate serum levels of leptin and ghrelin and their correlation with metabolic and endocrine indices in PCOS. MATERIALS AND METHODS This case-control study was con...
