Background: Insulin resistance is found in both psoriasis and Behçet's disease. No study has yet explored whether preptin and amylin, two hormones associated with insulin resistance, are involved in the insulin resistance observed in patients with psoriasis and Behçet's disease.
Objectives: We aimed to explore how the amounts of preptin and amylin change in psoriasis and Behçet's disease and whether they are involved in the etiopathology of these two diseases, by comparing hormone levels in patients and healthy controls.
Methods: The study registered 30 patients with psoriasis, 30 patients with Behçet's disease, and 30 healthy volunteers (as a control group). Fasting blood sugar, triglyceride, LDL, VLDL, HDL, total cholesterol, HbA1c, C-peptide, insulin, and serum preptin and amylin levels were measured in all subjects.
Results: Serum preptin and amylin levels were significantly lower in the patients with psoriasis and Behçet's disease than in the control group (P < 0.001, P = 0.004, and P = 0.008, respectively). A comparison of the serum preptin and amylin levels between the patients with psoriasis and Behçet's disease did not reveal a statistically significant difference. Serum insulin level and The homeostasis model assessment of insulin resistance (HOMA-IR) index were significantly lower in the psoriasis patient group relative to the control group (P = 0.02 and P = 0.03, respectively), while the values for the Behçet's disease group did not differ significantly from those for the control group
Conclusions: Serum levels of preptin and amylin were significantly lower in patients with psoriasis and Behçet's disease, indicating that these hormones may be a factor for development of metabolic syndrome in these two diseases.

This study was planned to test whether follicular fluid (FF) levels of patatin-like phospholipase domain containing 3-gene (PNPLA3:adiponutrin), preptin, kisspeptin, and amylin change in polycystic ovarian syndrome (PCOS). A total of 40 infertile volunteers undergoing IVF/ICSI were included in the study. They were divided into two groups as PCOS (n=20) and control group without PCOS (n=20).

BACKGROUND Preptin and amylin are pancreatic hormones which participate in glucose homeostasis. This study aimed to evaluate how serum preptin and amylin levels are altered in polycystic ovary syndrome (PCOS) patients and healthy women based on BMI groups (<25 kg/m² and ≥25 kg/m²). MATERIAL AND METHODS This was a prospective randomized control study of 40 PCOS patients and 40 healthy women who were matched with respect to BMI (<25 kg/m² and ≥25 kg/m²).

Preptin is a peptide hormone co-secreted with insulin and amylin from pancreatic β cells. It has been demonstrated to have osteogenic effects both in vitro and in vivo. In the present study, serum preptin levels were measured in pre- and postmenopausal women with similar body mass indexes (BMIs) to elucidate its link with bone mineral density (BMD).

Cytokines and Hormones That Contribute to the Positive Association between Fat and Bone.

The positive association between body weight and bone density has been established in numerous laboratory and clinical studies. Apart from the direct effect of soft tissue mass on bone through skeletal loading, a number of cytokines and hormones contribute to the positive association between adipose and bone tissue, acting either locally in sites where cells of the two tissues are adjacent to each other or systemically through the circulation. The current review describes the effects of such local and systemic factors on bone physiology.
