Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

* Nesfatin-1 is an 82-amino acid polypeptide derived from the nucleobindin 2 (NUCB2) precursor proteins.
* It is a newly identified peptide. It is released from several tissues including forebrain, hindbrain, brainstem, spinal cord and adipose tissues.
* It plays an important role in hypothalamic pathways such as feeding inhibition, locomotion, stress modulation, thermogenesis, and reproduction.
* Several studies had demonstrated that nesfatin-1 associated with body mass index (BMI), insulin resistance and inflammatory response disorders.
* Polycystic ovary syndrome (PCOS) is one of the most common causes of infertility in women. It is characterized by hyperandrogenism, multiple ovarian cysts, oligomenorrhea/amenorrhea. Many mechanisms had been reported to be responsible for the pathophysiology of PCOS. The condition is thought to be interactions between hypothalamic-pituitary-ovarian, hypothalamic-pituitary-adrenal axis and metabolic disorders.
* The circulating level of nesfatin-1 in PCOS patients is controversial. Some studies reveal lower nesfatin-1 serum levels while others reveal higher level.
* Women with PCOS may have reduced dopamine production from the hypothalamus and elevated prolactin concentrations and this mechanism may be responsible for reproductive disorder.
* In PCOS, stimulation of reactive oxygen species (ROS) generation from mononuclear cells (MNCs) by hyperglycemia . The superoxide radical in particular is a ROS that is generated by the activity of membrane-bound nicotinamide adenine dinucleotide phosphate (NADPH) oxidase.
* Dopaminergic (DA) neurons are highly susceptible to ROS. DA is relatively unstable molecule and undergoes auto-oxidative metabolism in nigro striatal tract system, leading to ROS production. Nicotinamide can reduce hypothalamic dopamine in postnatal brains results in dopamine-deficient phenotypes. Nicotinamide prevents DA release induced by long-term perinatal asphyxia.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* PCOS patients in the age range 18 - 40 years old.
* Diagnosis of PCOS is based on the 2003 ESHRE/ASRM diagnostic criteria, according to which patients who had at least two of the following conditions are accepted as having PCOS:

1. Oligo or anovulation, defined by the presence of oligomenorrhea or amenorrhea, confirmed by luteal progesterone and normal serum follicle stimulating hormone (FSH) levels (1.0-10.0 IU/L).
2. Clinical hyperandrogenism signs which was defined as the presence of at least one of the following three features: hirsutism, acne, and androgenic alopecia. Biochemical hyperandrogenism was defined as a serum testosterone (T) level \>60 ng/dL (\>2.08 nmol/L).
3. PCOS manifestation was defined as the presence of \>12 unilateral follicles 2-9 mm in size on the ovary or having the least unilateral ovary volume of 10 cm3 by ultrasonography (the measurement was performed when there was no follicle \>10 mm). Ovarian volume was calculated by the formula \[0.5× ovarian length × thickness × width\]. In the case of transabdominal ultrasonography, the presence of at least 10 unilateral antral follicles was required.

Exclusion Criteria

* Patients (age \<18 or \> 40years),
* Other endocrinology diseases as diabetes mellitus or thyroid disorders, Brain disorders as pituitary adenoma or tumour or brain tumours or masses,
* Chronic diseases such as cardiovascular, hepatic, hematologic, chronic renal failure, hypertension, and cancer,
* Use of oral contraceptives, antiandrogenics, glucocorticoids, antihypertensives, antidiabetics and anti-obesity drugs as well as the cigarettes, alcohol, and patients unwilling to participate in the study.
