Objective: To determine whether visceral adipose tissue or serum RBP-4 were related with the risk increment of insulin resistance in normal BMI PCOS patients. Methods: This was a cross-sectional study conducted in normal body mass index PCOS patients at Yasmin Clinic, RSCM, Jakarta from July 2014 until March 2015. Diagnosis of PCOS was established using Rotterrdam (2003) criteria. Insulin resistance was confirmed by using ratio of HOMA-IR >1.4. Results: Among 40 subjects, 20 subjects (50%) belong insulin resistance group. Serum RBP-4 level was higher in insulin resistance group (p=0.06). After ROC analysis was conducted, area under curve for of serum RBP-4 was 69.9% (CI 95% -3754.77 - (186.60-7696.14, p=0.061)). Cut-off level of serum RBP-4 was 23814.5 ng/mL yielded sensitivity and specificity to a level of 60% and 60%, respectively. After logistic regression were analyzed, visceral adipose tissue demonstrated substantial association with the risk increment of insulin resistance in normal BMI PCOS patients. Conclusions: Visceral adipose tissue demonstrated substantial association with the risk increment of insulin resistance in normal BMI PCOS patients, independent with serum RBP-4 levels. Key words: body mass index, diagnosis, insulin resistance, PCOS, retinol binding protein-4   Abstrak Tujuan: Untuk menentukan apakah jaringan adiposa viseral atau serum RBP-4 berhubungan dengan peningkatan risiko resistensi insulin pada Sindrom Ovarium Polikistik dengan indeks masa tubuh normal. Metode: Studi potong lintang dilakukan pada subjek SOPK dengan IMT normal di Klinik Yasmin, RSCM, Jakarta sejak Juli 2014 sampai dengan Maret 2015. Penegakan diagnosis SOPK dilakukan dengan kriteria Rotterdam (2003). Resistensi insulin dikonfirmasi dengan pemeriksaan rasio HOMA-IR > 1.4 Hasil: Diantara 40 subjek, sebanyak 20 subjek (50%) mengalami resistensi insulin. Kadar serum RBP-4 lebih tinggi pada kelompok resistensi insulin (p=0.06). Setelah dilakukan analisis Receiver Operating Curve (ROC), serum RBP-4 memiliki Area Under the Curve  (AUC) sebesar 69.9% (IK 95% -3754.77 - (186.60-7696.14, p=0,061)). Titik potong kadar serum RBP-4 adalah 23814.5 ng/mL dengan sensitivitas dan spesifisitas masing-masing 60% dan 60%. Setelah dilakukan analisis regresi logistik, jaringan adiposa viseral menunjukan asosiasi yang kuat dengan terjadinya resistensi insulin pada pasien SOPK dengan IMT normal. Kesimpulan: Jaringan adiposa viseral menunjukan asosiasi yang kuat dengan terjadinya resistensi insulin pada SOPK dengan IMT normal, independen terhadap kadar serum RBP-4.

Atherosclerotic Process

Although many preventive and treatment approaches have been proposed, cardiovascular disease (CVD) remains one of the leading causes of deaths worldwide. Current epidemiological data require the specification of new causative factors, as well as the development of improved diagnostic tools to provide better cardiovascular management. Excessive accumulation of adipose tissue among patients suffering from obesity not only constitutes one of the main risk factors of CVD development but also alters adipokines. Increased attention is devoted to bioactive adipokines, which are also produced by the adipose tissue. The retinol-binding protein 4 (RBP4) has been associated with numerous CVDs and is presumably associated with an increased cardiovascular risk. With this in mind, exploring the role of RBP4, particularly among patients with obesity, could be a promising direction and could lead to better CVD prevention and management in this patient group. In our review, we summarized the current knowledge about RBP4 and its association with essential aspects of cardiovascular disease—lipid profile, intima-media thickness, atherosclerotic process, and diet. We also discussed the RBP4 gene polymorphisms essential from a cardiovascular perspective.

Obesity and obesity-related disorders play an important role in clinical medicine. Adipose tissue, with its soluble mediators called adipocytokines, has emerged as a major endocrine organ. These adipocytokines comprise many mediators such as adiponectin, PBEF (pre-B-cell-enhancing factor)/visfatin, leptin, resistin, retinol-binding protein-4 and others. They play major roles in key aspects of metabolism, such as insulin resistance, fatty acid oxidation, inflammation and immunity. Adiponectin, a prototypic adipocytokine, is of importance in the regulation of insulin resistance, as circulating levels are decreased in obesity and diseases associated with insulin resistance. Besides its major role in regulation of insulin sensitivity, recent evidence suggests potent anti-inflammatory functions for adiponectin. These effects are paralleled by other immune-regulatory properties, such as regulation of endothelial cell function. The in vitro effects of adiponectin have been corroborated by several studies demonstrating potent in vivo anti-inflammatory effects. Many other adipocytokines, such as PBEF/visfatin, leptin, resistin or retinol binding protein-4, are involved in the physiology and pathophysiology of adipocytes, adipose tissue and related diseases. PBEF/visfatin, another recently characterized adipocytokine, has been linked to several inflammatory disease states beyond insulin resistance, such as acute lung injury or inflammatory bowel diseases. It has been recognized for many decades that obesity is accompanied by an increase in cancer and potentially some immune-mediated diseases. Understanding this new exciting world of adipocytokines will be of importance in the development of novel therapies for obesity-associated diseases.

Visfatin/Nampt, vaspin, and retinol binding protein-4 (RBP-4) play an important role in insulin resistance. The objectives of this study were to measure visfatin/Nampt, vaspin, and RBP-4 concentrations in blood, liver, muscle, subcutaneous, omental, and mesenteric adipose tissues in morbidly obese subjects and investigate their relationship to insulin resistance. Blood and tissue samples were collected from 38 morbidly obese subjects during Roux-en-Y surgery. Insulin resistance biomarkers were measured using standard kits. Visfatin/Nampt, vaspin, and RBP-4 gene expression levels in tissues were measured using real-time PCR. Their protein concentrations in blood and tissues were measured using ELISA kits. Diabetic subjects had significantly higher homeostasis model of assessment-insulin resistance and age and lower blood HDL-cholesterol concentrations than nondiabetic and prediabetic subjects. Diabetic and prediabetic subjects had significantly higher blood concentrations of visfatin/Nampt and vaspin than nondiabetic subjects. Liver RBP-4 concentrations were positively associated with blood glucose concentrations. Blood insulin resistance biomarker levels were positively associated with visfatin/Nampt concentrations in omental adipose tissue and liver, and vaspin concentrations in mesenteric adipose tissue. In conclusion, the correlations of visfatin/Nampt, vaspin, and RBP-4 with insulin resistance are tissue dependent.
