Background: Leptin resistance which leads to excessive circulating leptin levels is thought to affect ovarian function. This study aimed to study the correlation between serum leptin levels with insulin resistance in patients with polycystic ovary syndrome.Materials and Methods: This cross-sectional study was undertaken in several teaching hospitals in Makassar, Indonesia. We included patients diagnosed with polycystic ovary syndrome (PCOS) aged 18-40 years old. Serum leptin levels were examined in all eligible subjects using the enzyme-linked immunosorbent assay (ELISA) method. The results obtained were further analyzed statistically.Results: Approximately 53 PCOS subjects were included in this study, 25 subjects with insulin resistance and 28 subjects without insulin resistance. After examining serum leptin levels, we found that leptin is directly proportional to insulin resistance (p<0.001). We even found a strong positive correlation between serum leptin levels with homeostatic model assessment for insulin resistance (HOMA-IR) levels (r=0.659; p<0.001). Leptin was found to be independent of HOMA-IR, not influenced by confounding factors such as body mass index (BMI) (p=0.090).Conclusion: There was a significant correlation between serum leptin levels and HOMA-IR values in PCOS patients. This correlation was found to be significant regardless of patient's BMI, therefore is considered to have a direct effect on insulin resistance in PCOS.Keywords: polycystic ovary syndrome, leptin, insulin resistance, HOMA-IR
Tujuan: Menganalisis perbandingan ekspresi KISSPEPTIN-10 antara pasien tidak preeklamsia, preeklamsia berat, dan preeklamsia berat dengan komplikasi. Metode: Penelitian ini menggunakan desain kontrol kasus yang dilakukan pada ibu hamil preeklamsia berat dengan dan tanpa komplikasi sebagai kelompok kasus dan ibu hamil tidak preeklamsia berat sebagai kontrol di RSUP dr. Wahidin Sudirohusodo dan rumah sakit jejaring Fakultas Kedokteran Universitas Hasanuddin. Pengambilan sampel dilakukan dengan consecutive sampling. Kriteria inklusi yaitu ibu hamil dengan preeklamsia berat dan preeklamsia berat dengan komplikasi. Kriteria eksklusi yaitu pasien dengan hipertensi kronik, penyakit tiroid, dan penyakit ginjal sebelum kehamilan dan plasenta previa. Ekspresi KISSPEPTIN-10 diukur secara imunohistokimia dari plasenta saat melahirkan. Data dianalisis dengan uji chi square dan uji Kruskal Wallis. Data dianalisis dengan program SPSS. Hasil: Hasil ini diperoleh 88 subyek penelitian yang terdiri atas 30 pasien kelompok tidak preeklamsia, 30 pasien kelompok preeklamsia berat dan 28 pasien kelompok preeklamsia berat dengan komplikasi. Ekspresi KISSPEPTIN-10 berbeda signifikan antara kelompok tidak preeklamsia berat, preeklamsia berat, dan preeklamsia berat dengan komplikasi (p<0,05). Kesimpulan: Semakin tinggi ekspresi KISSPEPTIN-10 sejalan dengan semakin beratnya derajat preeklamsia berat.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
