Research Center for Biochemistry and Nutrition in Metabolic Diseases, Kashan University of Medical Sciences, Kashan, I.R. Iran.

Background: Data on the effects of omega-3 fatty acid supplementation on clinical symptoms and metabolic profiles in patients with endometrial hyperplasia (EH) are limited. This intervention was performed to assess the effects of omega-3 fatty acid supplementation on clinical symptoms and metabolic profiles in patients with endometrial hyperplasia (EH).

Methods: This randomized, double-blind, placebo-controlled trial was conducted among 40 women diagnosed with simple endometrial hyperplasia (EH). EH diagnosis was performed based on specific diagnostic procedures of biopsy. Participants were randomised into two groups to intake 1,000 mg omega-3 fatty acid supplements from flaxseed oil ( = 20) or placebo ( = 20), twice a day for 12 weeks. Fasting blood samples were taken at baseline and after the 12-week intervention to determine related markers.

Results: Compared with the placebo, omega-3 fatty acid supplementation significantly decreased fasting plasma glucose (FPG) (-7.1 ± 9.6 vs. +2.0 ± 4.9 mg/dL, = 0.001), serum insulin levels (-1.5 ± 4.6 vs. +1.6 ± 3.9 μIU/mL, = 0.02) and homeostasis model of assessment-insulin resistance (HOMA-IR) (-0.4 ± 1.1 vs. +0.4 ± 1.0, = 0.02). In addition, a significant increase in plasma total antioxidant capacity (TAC) (+102.6 ± 69.6 vs. +5.0 ± 37.1 mmol/L, < 0.001) and total glutathione (GSH) levels (+63.6 ± 84.9 vs. -3.0 ± 69.4 μmol/L, = 0.01) were seen following the supplementation of omega-3 fatty acid compared with the placebo. Omega-3 fatty acid supplementation had no significant effect on regression, lipid profiles, and other biomarkers of inflammation and oxidative.

Conclusions: In conclusion, we found that omega-3 fatty acid administration for 12 weeks to subjects with EH significantly improved FPG, insulin, HOMA-IR, TAC and GSH levels, but did not influence regression, lipid profiles, and other biomarkers of inflammatory and oxidative stress.

The Effects of Folic Acid Supplementation on Recurrence and Metabolic Status in Endometrial Hyperplasia: A Randomized, Double-Blind, Placebo-Controlled Trial.

Arch Iran Med 2018 10 1;21(10):452-459. Epub 2018 Oct 1.

Research Center for Biochemistry and Nutrition in Metabolic Diseases, Kashan University of Medical Sciences, Kashan, I.R. Iran.

Background: Data on the effects of folic acid supplementation on clinical symptoms and metabolic profiles of patients with endometrial hyperplasia (EH) are limited. This investigation was performed to evaluate the effects of folic acid supplementation on clinical symptoms and metabolic status of patients with EH.

Methods: This randomized, double-blind, placebo-controlled trial was conducted among 60 women diagnosed with EH. Diagnosis of EH was made based on biopsy results. Participants were randomly allocated to 2 groups to take 5 mg/d folic acid supplements (n = 30) or placebo (n = 30) for 12 weeks.

Results: After the 12-week intervention, folic acid supplementation significantly decreased fasting plasma glucose (β -3.99 mg/ dL; 95% CI, -7.39, -0.59; P = 0.02), serum insulin levels (β -2.82 µIU/mL; 95% CI, -4.86, -0.77; P = 0.008), homeostasis model assessment for insulin resistance (β -0.68; 95% CI, -1.20, -0.17; P = 0.009), triglycerides (β -16.47 mg/dL; 95% CI, -28.72, -4.22; P = 0.009) and very-low-density lipoprotein (VLDL) cholesterol (β -3.29 mg/dL; 95% CI, -5.74, -0.84; P = 0.009), and significantly increased the quantitative insulin sensitivity check index (β 0.01; 95% CI, 0.004, 0.03; P = 0.01) compared with the placebo. Additionally, folic acid intake resulted in a significant reduction in serum high sensitivity C-reactive protein (hs-CRP) (β -0.36 mg/L; 95% CI, -0.52, -0.21; P < 0.001) compared with the placebo. Folic acid supplementation did not affect other metabolic parameters.

Conclusion: In conclusion, we found that folic acid administration for 12 weeks to subjects with EH improved glycemic control, triglycerides, VLDL-cholesterol and hs-CRP levels, but did not influence recurrence and other metabolic profiles.

Ann Nutr Metab 2018 21;72(2):151-160. Epub 2018 Feb 21.

Research Center for Biochemistry and Nutrition in Metabolic Diseases, Kashan University of Medical Sciences, Kashan, Iran.

Objective: This study was conducted to evaluate the effects of vitamin D supplementation on the recurrence and metabolic status of patients with cervical intraepithelial neoplasia grade 2 or 3 (CIN2/3).

Methods: This randomized, double-blind, placebo-controlled trial was carried out among 58 women diagnosed with CIN2/3. Participants were randomly assigned into 2 groups to receive either 50,000 IU vitamin D3 (n = 29) or placebo (n = 29) every 2 weeks for 6 months.

Results: The recurrence rate of CIN1/2/3 was 18.5 and 48.1% in the vitamin D and placebo groups respectively (p = 0.02). When we excluded CIN1, the recurrence rate of CIN2/3 became nonsignificant. Vitamin D supplementation significantly decreased fasting plasma glucose (-7.8 ± 9.2 vs. -1.1 ± 8.6 mg/dL, p = 0.006) and insulin levels (-3.2 ± 4.8 vs. -0.9 ± 3.4 µIU/mL, p = 0.03), and significantly increased quantitative insulin sensitivity check index (0.01 ± 0.02 vs. 0.002 ± 0.01, p = 0.02) compared with the placebo. Additionally, there was a significant decrease in high-sensitivity C-reactive protein (-815.3 ± 1,786.2 vs. 717.5 ± 1,827.3 ng/mL, p = 0.002) and a significant increase in total antioxidant capacity (113.4 ± 137.4 vs. -53.7 ± 186.7 mmol/L, p < 0.001) following the supplementation of vitamin D compared with the placebo.

Conclusions: Vitamin D3 supplementation for 6 months among women with CIN2/3 had beneficial effects on CIN1/2/3 recurrence and metabolic status; however, it did not affect CIN2/3 recurrence.

Eur J Clin Invest 2018 Mar 8;48(3). Epub 2018 Feb 8.

Department of Gynecology and Obstetrics, School of Medicine, Kashan University of Medical Sciences, Kashan, Iran.

Background: This study was conducted to determine the effects of fish oil administration on gene expression related to insulin, lipid and inflammation in women with polycystic ovary syndrome (PCOS).

Materials And Methods: This randomized, double-blind, placebo-controlled trial was conducted among 40 subjects with PCOS, aged 18-40 years. Subjects were randomly allocated into two groups to take either 1000 mg omega-3 fatty acids from fish oil (n = 20) or placebo (n = 20) twice a day for 12 weeks. Gene expression related to insulin, lipid and inflammation was quantified in peripheral blood mononuclear cells (PBMC) of PCOS women with RT-PCR method.

Results: Our study demonstrated that after the 12-week intervention, compared with the placebo, fish oil supplementation upregulated gene expression of peroxisome proliferator-activated receptor gamma (PPAR-γ) (P < .001) in PBMC of subjects with PCOS. In addition, compared to the placebo, taking fish oil supplements downregulated gene expression of interleukin-1 (IL-1) (P = .02) and interleukin-8 (IL-8) (P = .01) in PBMC of subjects with PCOS. We did not observe any significant effect of fish oil supplementation on gene expression of lipoprotein(a) [LP(a)], low-density lipoprotein receptor (LDLR), glucose transporter 1 (GLUT-1), tumour necrosis factor alpha (TNF-α) and transforming growth factor beta (TGF-β) in PBMC of subjects with PCOS.

Conclusions: Overall, fish oil supplementation for 12 weeks to subjects with PCOS significantly improved gene expression of PPAR-γ, IL-1 and IL-8, but did not influence gene expression of LP(a), LDLR, GLUT-1, TNF-α and TGF-β.

Exp Clin Endocrinol Diabetes 2018 Apr 8;126(4):222-228. Epub 2017 Nov 8.

Research Center for Biochemistry and Nutrition in Metabolic Diseases, Kashan University of Medical Sciences, Kashan, I.R. Iran.

Objective: This study was conducted to evaluate the effects of flaxseed oil omega-3 fatty acids supplementation on metabolic status of patients with polycystic ovary syndrome (PCOS).

Methods: This randomized double-blind, placebo-controlled trial was conducted on 60 women with PCOS according to the Rotterdam criteria aged 18-40 years old. Participants were randomly assigned into two groups to receive either 1,000 mg flaxseed oil omega-3 fatty acids (n=30) or placebo (n=30) twice a day for 12 weeks. Metabolic, endocrine, inflammatory factors were quantified at baseline and after the 12-week intervention.

Results: After the 12-week intervention, compared to the placebo, flaxseed oil omega-3 supplementation significantly decreased insulin values (-2.6±7.7 vs.+1.3±3.9 µIU/mL, P=0.01), homeostasis model of assessment-estimated insulin resistance (-0.7±1.7 vs.+0.3±0.9, P=0.01), mF-G scores (-1.2±1.7 vs. -0.1±0.4, P=0.001), and increased quantitative insulin sensitivity check index (+0.01±0.02 vs. -0.01±0.02, P=0.01). In addition, supplementation with flaxseed oil omega-3 resulted in significant decreases in serum triglycerides (-5.1±20.9 vs.+9.7±26.1 mg/dL, P=0.01), VLDL-cholesterol (-1.0±4.2 vs.+1.9±5.2 mg/dL, P=0.01) and high-sensitivity C-reactive protein (hs-CRP) (-1.6±3.1 vs.+0.2±1.5 mg/L, P=0.004) compared to the placebo. We did not see any significant effect of flaxseed oil omega-3 supplementation on hormonal and other lipid profiles, and plasma nitric oxide levels.

Conclusions: Overall, flaxseed oil omega-3 supplementation for 12 weeks in women with PCOS had beneficial effects on insulin metabolism, mF-G scores, serum triglycerides, VLDL-cholesterol and hs-CRP levels, but did not affect hormonal and other lipid profiles, and plasma nitric oxide levels.

The Effect of Zinc Supplementation on Expressed Levels of Peroxisome Proliferator-Activated Receptor Gamma and Glucose Transporter Type 1 Genes in Newborns of Women with Gestational Diabetes Mellitus.

Biol Trace Elem Res 2017 Feb 22;175(2):271-277. Epub 2016 Jun 22.

Research Center for Biochemistry and Nutrition in Metabolic Diseases, Kashan University of Medical Sciences, Kashan, Iran.

The current study was designed to determine the beneficial effects of zinc supplementation on expressed levels of peroxisome proliferator-activated receptor gamma (PPAR-γ) and glucose transporter type 1 (GLUT1) genes in newborns of women with gestational diabetes mellitus (GDM). This randomized, double-blind, placebo-controlled clinical trial was performed among 40 women with GDM. Patients were randomly allocated to intake either 233 mg zinc gluconate (containing 30 mg zinc) (n = 20) or a placebo (n = 20) for 6 weeks. PPAR-γ and GLUT1 mRNA levels were quantified in umbilical cord blood of newborns of women with GDM. After 6 weeks of intervention, the change in serum zinc levels was greater in women consuming zinc than in the placebo group (+11.1 ± 13.4 vs. -4.8 ± 17.3 mg/dL, P = 0.002). Quantitative results of RT-PCR demonstrated that compared with the placebo, zinc supplementation resulted in a significant increase of expressed levels of PPAR-γ mRNA (P < 0.001) and GLUT1 mRNA (P < 0.001) in umbilical cord blood of newborns of women with GDM. Taken together, the current study demonstrated that zinc supplementation for 6 weeks among GDM women increased the mRNA levels of PPAR-γ and GLUT1 in their newborns compared with the placebo group.
