The influences of vitamin D and omega-3 co-supplementation on clinical, metabolic and genetic parameters in women with polycystic ovary syndrome

Objective: The aim of this study was to evaluate the effect of the co-administration of vitamin D and omega-3fatty acid on clinical, metabolic and genetic parameters in women with polycystic ovary syndrome (PCOS). Methods: This randomized, double-blinded, placebo-controlled clinical trial was conducted on 60 subjects, aged 18–40 years old with PCOS. Subjects were randomly allocated to take either 50,000 IU vitamin D every 2 weeks plus 2000 mg/day omega-3 fatty acid from fish oil (n=30) or placebo (n=30) for 12 weeks. Gene expression analysis of inflammatory cytokines was conducted on peripheral blood mononuclear cells (PBMCs) of PCOS women using RT-PCR method. Results: Vitamin D and omega -3 fatty acid co-supplementation significantly decreased serum total testosterone levels (−0.2 ± 0.5 vs.+0.1 ± 0.4 ng/mL, P=0.02) compared with the placebo. In addition, vitamin D and omega-3 fatty acid co-supplementation resulted in a significant improvement in beck depression inventory (−1.4 ± 1.6 vs. −0.5 ± 0.6, P=0.01), general health questionnaire scores (−4.5 ± 4.3 vs. −1.9 ± 2.3, P=0.005) and depression anxiety and stress scale scores (−5.0 ± 5.1 vs. −2.3 ± 3.5, P=0.01) compared with the placebo. Additionally, vitamin D and omega-3 fatty acid co-administration significantly decreased serum high-sensitivity C-reactive protein (hs-CRP) (−1.2 ± 1.9 vs.+0.1 ± 0.7 mg/L, P=0.001) and malondialdehyde (MDA) levels (−0.4 ± 0.4 vs.+0.2 ± 0.6 μmol/L, P<0.001), and significantly increased plasma total antioxidant capacity (TAC) levels (+ 114.6 ± 122.2 vs. -2.4 ± 168.2 mmol/L, P=0.003) compared with the placebo. Results of RT-PCR demonstrated that vitamin D and omega-3 fatty acid co-supplementation significantly downregulated gene expression of interleukin-1 (IL-1) (P=0.03), and upregulated vascular endothelial growth factor (VEGF) (P=0.004) in PBMCs of subjects with PCOS, when compared with placebo. Conclusions: Overall, the co-administration of vitamin D and omega-3 fatty acid for 12 weeks had beneficial effects on mental health parameters, serum total testosterone, hs-CRP, plasma TAC and MDA levels, and gene expression of IL-1 and VEGF among women with PCOS

Lived experiences of patients suffering from acute Old World Cutaneous Leishmaniasis: A qualitative content analysis study from Iran

Background: The aim of this study was to explore the experiences of patients who suffer from acute cutaneous leishmaniasis in Iran, focusing on quality of life. Methods: The study was conducted at two different sites in Iran in 2010-2011. Individual in-depth interviews were conducted with six men and six women parasitologically confirmed acute cutaneous leishmaniasis. Interviews were recorded, transcribed verbatim, and translated into English. Qualitative content analysis was used for data analysis. Results: The participants, aged 23 to 63yr, had mild to severe disease. Based on the analysis four main themes were developed. "Fearing an agonizing disease" reflects patients' experiences of disease development resulting in sadness and depression, "struggling to cope" and "taking on the blame" both illustrate how patients experience living with the disease, which included both felt and enacted stigma as major social concerns. "Longing for being seen and heard" refers to patients' experiences with healthcare as well as their expectations and demands from communities and healthcare to be involved in closing the knowledge and awareness gap. Conclusion: Mental and social dimensions of cutaneous leishmaniasis were complex and adversely affected patients' lives by causing psychological burden and limiting their social interactions. Health authorities have to plan programs to increase the disease awareness to prevent the existing stigma to improve patients' social condition and medical care. © 2018, Tehran University of Medical Sciences

Calcium plus vitamin D supplementation influences biomarkers of inflammation and oxidative stress in overweight and vitamin D-deficient women with polycystic ovary syndrome: A randomized double-blind placebo-controlled clinical trial

Objective This study was conducted to determine the effects of calcium plus vitamin D supplementation on inflammatory factors and biomarkers of oxidative stress among overweight vitamin D-deficient women with polycystic ovary syndrome (PCOS). Design, Patients and Measurements This randomized double-blind placebo-controlled clinical trial was performed among 104 overweight vitamin D-deficient women diagnosed with PCOS aged 18-40 years. Participants were randomly divided into four groups. Group A received 1000 mg calcium daily and vitamin D placebo weekly (N = 26), group B 50000 IU vitamin D weekly and calcium placebo daily (N = 26), group C 1000 mg calcium daily plus 50000 IU vitamin D weekly (N = 26) and group D calcium placebo daily plus vitamin D placebo weekly (N = 26) for 8 weeks. Fasting blood samples were taken at baseline and 8 weeks after intervention to measure inflammatory factors and biomarkers of oxidative stress. Results After 8 weeks, individuals taking calcium plus vitamin D supplements had greater decreases in homoeostatic model assessment beta-cell function (HOMA-B) score (-11·1 vs -8·6, -3·4 and 13·7, respectively, P = 0·03), serum high-sensitivity C-reactive protein (hs-CRP) (-948·3 vs 802·3, -383·8 and 618·2 ng/ml, respectively, P = 0·04) and plasma malondialdehyde (MDA) concentrations (-0·6 vs -0·5, -0·1 and 0·6 μmol/l, respectively, P = 0·009), and significant increases in plasma total antioxidant capacity (TAC) (35·2 vs 21·1, 22·5 and -153·8 mmol/l, respectively, P = 0·006) and glutathione (GSH) levels (216·0 vs 3·9, -47·5 and -160·8 μmol/l, respectively, P = 0·001) compared with calcium alone, vitamin D alone and placebo groups. Calcium plus vitamin D cosupplementation did not influence plasma NO and catalase levels. Conclusions We found that calcium plus vitamin D cosupplementation for 8 weeks among overweight and vitamin D-deficient women with PCOS had beneficial effects on inflammatory factor and biomarkers of oxidative stress. © 2015 John Wiley & Sons Ltd

Zinc Supplementation and the Effects on Pregnancy Outcomes in Gestational Diabetes: A Randomized, Double-blind, Placebo-controlled Trial

Objective: The current study was designed to determine the beneficial effects of zinc intake on biomarkers of inflammation, oxidative stress, and pregnancy outcomes among pregnant women with gestational diabetes (GDM). Methods: This randomized, double-blind, placebo-controlled clinical trial was conducted among 50 women with GDM. Patients were randomly allocated to intake either 233 mg zinc gluconate (containing 30 mg zinc) (n=25) or a placebo (n=25) for 6 weeks. Fasting blood samples were taken at the fist of the study and after 6 weeks of intervention to quantify related variables. Newborn's weight, height, head circumference, Apgar score, and hyperbilirubinemia were determined. Results: The change in serum zinc levels after 6 weeks of supplementation was greater in women consuming zinc than in the placebo group (+8.5±13.5 vs. -3.6±16.2 mg/dL, P=0.006). Changes in serum high sensitivity C-reactive protein (hs-CRP) (-110.1±1 475.5 vs. +1 137.8±2 429.2 ng/mL, P=0.03) and plasma total antioxidant capacity (TAC) concentrations (+60.0±129.0 vs. -28.4±81.4 mmol/L, P=0.006) were significantly different between the supplemented women and placebo group. We did not find any significant effect of zinc administration on pregnancy outcomes. Conclusion: Taken together, zinc administration among patients with GDM was associated with decreased hs-CRP and increased TAC concentrations; however, it did not influence maternal plasma nitric oxide (NO), glutathione (GSH), malondialdehyde (MDA) levels, or pregnancy outcomes. © J.
