Overweight Polycystic Ovary Syndrome Patients Research Articles

The effect of Bushenhuoxue nutritional decoction in the treatment of overweight patients with polycystic ovarian syndrome.

To assess the effect of Traditional Chinese Medicine (TCM) nutrition treatment (Bushenhuoxue nutritional decoction) in overweight patients with polycystic ovary syndrome (PCOS). Retrospective analysis of 96 overweight patients with PCOS who received treatment in our hospital from October 2020 to June 2022 was done. Among them, 46 patients received routine drug treatment and daily dietary intervention (control group), while 50 patients received additional TCM nutrition support in addition to routine treatment (observation group). Glucose and lipid metabolism indicators and hormone levels were compared between the two groups before and after the treatment. Ovulation rate, pregnancy rate, and adverse reactions were compared between both groups one year after the treatment. After treatment, the improvement of glucose and lipid metabolism indicators and hormone levels in the observation group was significantly better than in the control group (P<0.05). After treatment, the TCM syndrome scores of the two groups were lower than that before treatment (P < 0.001), and the TCM syndrome scores of the observation group was lower than that of the control group (P < 0.001).Ovulation and pregnancy rates were significantly higher in the observation group compared to the control group at 1-year follow up (P<0.05), and the incidence of adverse reactions in the observation group was significantly lower than that in the control group (P<0.05). Combined with conventional drug treatment, TCM nutrition treatment can significantly improve glucose and lipid metabolism, hormone levels, and TCM syndrome of overweight PCOS patients, increase the ovulation and pregnancy rates, and reduce potential adverse reactions.

Lipid accumulation product is an effective predictor of metabolic syndrome in non-obese women with polycystic ovary syndrome.

To explore the correlation of lipid accumulation product (LAP) with metabolic syndrome (MS) and to assess the predictive value of LAP for MS risk in polycystic ovary syndrome (PCOS) with different body mass index (BMI). A total of 242 PCOS patients and 150 controls were recruited and divided into normal-weight, overweight, and obese groups, then further divided into MS and without MS subgroups. Clinical and anthropometric variables and laboratory results were recorded. LAP was calculated from waist circumference (WC) and triglyceride using sex-specific formulae. Logistic regression analysis and receiver operating characteristic (ROC) curve were applied to determine and analyze the predictive value of LAP for MS. The prevalence of MS among PCOS patients was 45.04%, which was significantly higher than that of the controls (10%). Stratified by BMI, the incidence of MS in the normal-weight, overweight, and obese PCOS groups were 15.58%, 41.43%, and 71.58%, respectively. Logistic regression analysis indicated that LAP was an independent risk factor for MS in both normal-weight and overweight groups; however, the results were not significant in the obese group. ROC curve analysis showed that LAP had an outstanding discrimination index for MS in normal-weight (AUC=0.960, cut-off value=42.5) and overweight (AUC=0.937, cut-off value=47.93) PCOS patients, with a sensitivity of 0.917/0.931 (normal-weight/overweight) and a specificity of 0.969/0.854 (normal-weight/overweight), respectively. Normal-weight and overweight PCOS patients also have a fairly high incidence of MS and should receive as much attention as obese patients. Compared to applying multiple clinical indicators, LAP is more convenient and facilitates acquiring early and accurate diagnoses of MS among non-obese PCOS patients using fewer MS markers.

Observational study of usage of a combination of inositols with alpha-lactalbumin (Ovamystic) in the treatment of menstrual irregularity in PCOS

This observational study aimed at evaluating the effects of Ovamystic in groups of women with menstrual irregularities in Polycystic Ovary Syndrome (PCOS), treated at Mahavir Hospital and Manish IVF Center Surendranagar, Gujarat. : The study involved 126 normal weight or overweight PCOS patients aged 18 to 30 years, with menstrual irregularity and anovulation &amp;#62; 12 months. Patients were administered orally chewable tablets of Ovamystic (myo-inositol 1100mg + D-chiro-inositol 27.6mg + alpha-lactalbumin 50mg + chromium picolinate 400mcg + vitamin D2 400IU) twice daily for 6 months. The primary outcome was measured in terms of certain parameters like changes in body mass index (BMI), change in ovarian volume, and change in frequency and duration of menstrual cycle (M-SCORE). Alpha-lactalbumin is effective in increasing myo-inositol intestinal absorption, which is very useful in reducing the therapeutic failure of myo-inositol in some patients (inositol resistant subjects).: Recovery was general, and its relevance was higher when the starting point was further away from the normal range. The most important results with Ovamystic were obtained in correcting the menstrual irregularity, and also decreasing ovarian volume and BMI. No significant adverse effects were detected in this group of patients, and Ovamystic had good tolerability and compliance. This observational study demonstrated that Ovamystic improves important parameters in PCOS patients characterized by different metabolic profiles like BMI, menstrual irregularities, and ovarian volume.

Marrow adipose tissue is increased in overweight and obese women with PCOS independently of hyperandrogenism related obesity and metabolic disorders.

This study aimed to investigate the increase in bone marrow adipose tissue (BMAT) in overweight and obese women with polycystic ovary syndrome (PCOS) and its relationship with hyperandrogenism, obesity, and metabolic disorders. The study included 87 overweight or obese women with PCOS (mean age 29 ± 4 years), as well as 87 age-matched controls recruited from a separate population study. All PCOS patients were measured for anthropometric features, abdominal adipose tissue areas, BMAT, biochemistry, and sex hormones. BMAT was compared between the PCOS patients and controls. In PCOS patients, subgroup comparisons of BMAT and its associations with body adiposity indices, biochemistry, and sex hormones were analyzed. The odds ratios (ORs) of elevated BMAT (defined as BMAT ≥ 38%) were calculated. On average BMAT was increased by 5.6% ( ± 11.3%) in PCOS patients compared to controls. BMAT were significantly higher in the upper tertiles of total cholesterol (TC) and low density lipoprotein-cholesterol (LDL-C). BMAT was not correlated with abdominal adiposity indices or biochemistry except for LDL-C (r = 0.253-0.263, p = 0.014-0.018). LDL-C was not significantly different between the normal and abnormal androgen PCOS subgroups (p = 0.10-0.887). LDL-C, follicle stimulating hormone (FSH), and total testosterone (TT) were risk factors for elevated BMAT, with ORs of 1.899 (p = 0.038-0.040), 1.369 (p = 0.030-0.042), and 1.002 (p = 0.040-0.044) for each unit increase, respectively. BMAT was increased in overweight and obese PCOS patients, but the increase in BMAT was not associated with the hyperandrogenism related obesity or metabolic disorders.

The Nutritional Intervention Improves the Metabolic Profile of Overweight and Obese PCOS Along with the Differences in Gut Microbiota.

Previous studies had shown that the gut microbiota of polycystic ovary syndrome (PCOS) patients had significant differences from those of healthy individuals, which may play an important role in the pathogenesis of PCOS. Lifestyle intervention, such as nutritional intervention, could improve the metabolic profiles and PCOS-like phenotypes of PCOS patients. Meanwhile, nutritional intervention could rapidly alter and reshape the distribution of gut microbiota in individuals. Therefore, we sought to investigate the differences in gut microbiota in overweight and obese PCOS patients with or without nutritional intervention. Thirty-six overweight and obese PCOS patients were finally enrolled in the study. Eighteen individuals who refused nutritional intervention (RNI) were collected as the RNI group. Eighteen individuals who received the nutritional intervention were collected as the pre-NI group before the nutritional intervention. And they were also collected as the NI group after the nutritional intervention for 4-12weeks. Significant decreases in BMI, FBG, TC, TG, APO A1, and APO B were observed when comparing the NI group with the pre-NI and RNI groups after the nutritional intervention for 4-12weeks. Meanwhile, the differences in the phylum Firmicutes, Bacteroidetes, and the species Eubacterium rectale, Flavonifractor plautii, and Bacteroides vulgatus between the NI and the RNI groups were observed, which may be potentially linked to the improved inflammatory state and PCOS-like phenotypes of overweight and obese PCOS individuals.

Impact of body mass index and vitamin D on serum AMH levels and antral follicle count in PCOS.

To investigate the effects of body mass index (BMI) values and 25(OH) vitamin D levels determined by Endocrine Society on serum Anti Mullerian Hormone (AMH) and antral follicle count (AFC) in women with polycystic ovary syndrome (PCOS). Sixty infertile women with PCOS and 30 age-matched women with unexplained infertility (UEI), were included. Patients in PCOS and control groups were divided into three subgroups according to their BMI values as normal, overweight and obese. Each BMI group was divided into three subgroups according to vitamin D levels. While AMH and vitamin D levels were determined at first admission, AFC was measured on the third day of cycle. BMI, AFC, and AMH levels of women with PCOS were significantly higher than the UEI group. AMH values of women with PCOS with normal BMI were found to be significantly higher than UEI controls with normal BMI. AMH values of overweight and obese PCOS patients and controls were similar. As BMI values of the PCOS group increased, vitamin D levels decreased significantly. Vitamin D levels of the patients in the PCOS group were found to be significantly lower than the control group. When evaluated according to BMI, the vitamin D levels of normal, overweight and obese women with PCOS were significantly lower than the UEI. Rising BMI in PCOS leads to a significant decrease in vitamin D and AMH. Deficiency, insufficiency or normality of vitamin D do not affect the main markers of ovarian reserve.

A Study on the Association between Subclinical Hypothyroidism and Polycystic Ovary Syndrome

Background: Polycystic ovary syndrome (PCOS) and hypothyroidism are endocrine and metabolic disorders. Hypothyroidism has been found to be related to changes in blood lipids and insulin insensitivity. However, the relationship between subclinical hypothyroidism (SCH) and endocrine disorders in PCOS patients remains unclear. The incidence of SCH in PCOS patients is increasing. Metabolomics methods have been used to investigate the differences in metabolites and metabolic pathways between normal body weight and overweight (not obese) PCOS patients with SCH. Understanding the association between PCOS and SCH can guide diagnosis and treatment. Methods: We performed an untargeted serum metabolomics analysis in 62 PCOS patients. From 38 PCOS patients with SCH, 24 were selected and divided into the overweight (n = 13) and normal weight (n = 11) groups. Differential metabolites were identified using ultra-high-performance liquid chromatography–quadrupole time-of-flight mass spectrometry analysis. The significance of metabolites was evaluated by calculating the variable importance in projection score (&gt; 1 and P &lt; 0.01) from partial least squares discriminant analysis (PLS-DA) and orthogonal PLS-DA models. Kyoto Encyclopedia of Genes and Genomes pathway analysis was conducted to investigate the metabolomic pathways. P &lt; 0.05 (Fisher’s exact test) was considered statistically significant. Results: In PCOS patients with SCH, significant differences in body weight, right ovary volume, homeostasis model assessment for insulin resistance value, insulin level at 2 h after a meal, and triglyceride level were observed between the overweight and normal weight groups. Twenty-six different metabolites were identified, mainly fatty acids and phosphatidylcholines, to have significantly levels in overweight patients with SCH. Moreover, 18 enriched metabolic pathways were identified, mainly biosynthesis of fatty acids and unsaturated fatty acids, digestion and absorption of proteins, aminoacyl-tRNA biosynthesis, and ATP-binding cassette (ABC) transporters. Conclusion: The interaction between body mass index and thyroid-stimulating hormone affects the metabolic status of PCOS patients. Overweight PCOS patients with SCH may have the worst metabolic status. The overweight and normal weight groups showed differences in glycerol phospholipid, sterol lipid, phosphatidylcholine, and androsterone sulphate levels. PCOS with SCH affects endocrine metabolism and ester metabolism through fatty acid biosynthesis, protein digestion and absorption, and ABC transporters.

Effect of orlistat during individualized comprehensive life-style intervention on visceral fat in overweight or obese PCOS patients

Objective To investigate the effect of orlistat combined with drospirenone/ethinylestradiol tablets (DRSP/EE) on the visceral fat area (VFA) compared to DRSP/EE-alone in overweight or obese patients with polycystic ovary syndrome (PCOS). Methods 90 PCOS patients [body mass index (BMI) ≥24kg/m2] were recruited for a prospective, open-label, 1:2 paired 3-monthly study. All were included during the per-protocol defined recruitment time and numbered according to the entry-order: group-1: No.1-60, orlistat plus DRSP/EE; group-2: No.61-90, DRSP/EE-alone. Both groups received the same comprehensive intervention in terms of individualized, standardized management and lifestyle monitoring such as diet and exercise. Primary study-endpoint was VFA, secondary endpoints were anthropometric indices, sex hormones and glucolipid metabolism. Within- and between-group analyses were performed. Results VFA [cm2] in group-1 after treatment decreased significantly (p = 0.001), and the between-group comparison was highly significant (p = 0.001). Body weight, hip circumference (HC), BMI, body fat (BF), free testosterone (FT) and low-density lipoprotein-cholesterol (LDL-C) significantly decreased in both groups (within-group analysis); the decrease in group-1 was significantly greater than in group-2 (p < 0.05). Systolic and diastolic blood pressure (SBP/DBP) and fasting plasma glucose (FPG) in group-1 were significantly decreased, significantly more in group-1 than in group-2 (p < 0.05). Conclusion This study is the first to investigate the effect of orlistat combined with DRSP/EE in overweight or obese PCOS patients compared with using DRSP/EE-alone. Orlistat combined with DRSP/EE was better than using DRSP/EE-alone in reducing VFA, body weight, FT, BP and FPG, which provides evidence for the choice of rational drug use in clinical practice.

Effect on the cardiovascular independent risk factor lipoprotein(a) in overweight or obese PCOS patients with ethinyl-estradiol/drospirenone alone or plus orlistat

Objective This study aimed to assess the effect on the cardiovascular independent risk factor Lipoprotein(a) [Lp(a)] in overweight or obese polycystic ovary syndrome (PCOS) patients with ethinyl-estradiol/drospirenone (EE/DRSP) alone or plus orlistat. Methods In this randomized controlled prospective study, 66 PCOS patients with overweight or obesity were matched according to age and BMI. All participants were randomly divided into two groups to receive EE/DRSP plus Orlistat (n = 33) or EE/DRSP alone (n = 33) for 3 months. Changes in cardiovascular risk factors including Lp(a), CRP, LDL-C, anthropometric assessments, variations in sex hormones related parameters, and in glucolipid metabolic index were evaluated after the intervention. Results Lp(a) and CRP were significantly decreased at 3 months only in the EE/DRSP plus Orlistat group. There were significant reductions in LDL-C, weight, BMI, waist circumference (WC), body fat percentage (BFP), FT in both groups compared to baseline. However, these reductions were significantly greater in EE/DRSP plus Orlistat group. The levels of HDL-C, TG, and SHBG significantly increased, while TT and LH significantly decreased in both groups over time. TC, FINS, FPG were not significantly changed in both groups after the intervention. Conclusions This is the first study found that EE/DRSP plus Orlistat could significantly decrease Lp(a) in overweight or obese PCOS patients. This result can be assessed as particularly important, because Lp(a) is well-known as an independent risk factor predicting an increased risk of cardiovascular diseases (CVDs).

Advanced therapy of overweight or obese polycystic ovary syndrome: a prospective study

ObjectiveTo investigate the effects of orlistat combined with drospirenone/ethinylestradiol tablets (DRSP/EE) on anthropometric indices, sexual hormones, hepatorenal function parameters of overweight or obese patients with polycystic ovary syndrome (PCOS). Methods75 overweight or obese PCOS patients [body mass index (BMI) ≥ 24 kg/m2] were recruited within the Department of Gynecological Endocrinology, Beijing Obstetrics and Gynecology Hospital, Capital Medical University, from April 2019 to January 2020, for a prospective, randomized, open-labelled comparing study. They were numbered one by one according to the order of recruitement and randomly divided into two groups, group 1 included 50 patients, orlistat plus DRSP/EE; group 2 included 25 patients treated with DRSP/EE alone. Both groups got the same comprehensive intervention in terms of individualized, standardized managment and monitoring of life-style like diet and exercise. The changes of anthropometric indices, sexual hormones, hepatorenal function parameters before and after three months of treatment in the two groups were compared . ResultsAfter three months of treatment, body weight, waist circumference (WC), hip circumference (HC) and BMI of both groups were significantly decreased (P < 0.05). The decrease of body weight, WC, HC and BMI in group 1 was significantly greater than those in group 2 (P < 0.05). Free testosterone and sex hormone–binding globulin in both groups were significantly changed (P < 0.05). There was no significant difference in the hepatorenal function parameters between the two groups after three months treatment (P > 0.05). ConclusionTo our knowledge our study is the first to investigate the effects of orlistat combined with DRSP/EE in overweight or obese PCOS patients comparing with the effect of using DRSP/EE alone. Orlistat combined with DRSP/EE was better than use DRSP/EE alone in getting weight loss, which provides an evidence for the choice of rational drug use in clinical practice.

Mediterranean Diet Combined With a Low-Carbohydrate Dietary Pattern in the Treatment of Overweight Polycystic Ovary Syndrome Patients.

ObjectivesTo determine the therapeutic effect of a Mediterranean diet (MED) combined with a low-carbohydrate (LC) dietary model in overweight polycystic ovary syndrome (PCOS) patients.MethodsIn this 12-week randomized controlled clinical trial, 72 overweight patients with PCOS were randomly assigned to one of two energy-restricted dietary models: the MED/LC diet or the Low fat (LF) diet. After the intervention, the number of the two groups returned to normal menstruation was counted. Body weight, body mass index (BMI), waist circumference, waist-hip ratio (WHR), body fat percentage (BF%), serum fasting insulin(FINS), fasting plasma glucose(FPG), insulin resistance index (HOMA-IR), quantitative insulin sensitivity index (QUIKI), total cholesterol (TC) and high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), triglyceride (TG), total testosterone (TT), luteinizing hormone (LH), follicle-stimulating hormone (FSH), and prolactin (PRL) were compared between 2 groups before and after intervention.ResultsMED/LC group had more significant reduction trend in weight (−6.10 ± 1.52 kg vs −4.79 ± 0.97 kg, P < 0.05), BMI (−2.12 ± 0.57 kg/m2 vs −1.78 ± 0.36 kg/m2, P < 0.05), WC (−6.12 ± 5.95 cm vs −3.90 ± 1.58 cm, P < 0.05), WHR (−0.06 ± 0.02 vs −0.03 ± 0.02, P < 0.05), BF% (−2.97% ± 1.78% vs −1.19% ± 0.91%, P < 0.05), TT (−0.20 ± 0.24 ng/mL vs 0.08 ± 0.11 ng/Ml, P < 0.001), LH (−5.28 ± 3.31 mIU/mL vs −3.39 ± 3.64 mIU/mL, P < 0.05), and LH/FSH (−1.18 ± 0.75 vs -0.66 ± 1.05, P < 0.05) compared with the LF group. In addition, FPG (0.05 ± 0.38 mmol/mL vs -0.50 ± 1.01 mmol/mL, P < 0.001), FINS (−4.88 ± 6.11 μU/mL vs −8.53 ± 5.61 μU/mL, P < 0.01), HOMA-IR index (−1.11 ± 1.51 vs −2.23 ± 0.25, P < 0.05), and QUIKI index (0.014 ± 0.016 vs 0.028 ± 0.019, P < 0.05) decreased significantly in the MED/LC group compared with the LF group. Comparing the changes in lipid parameters between the two groups (LF vs MED/LC), significant differences in TG (−0.33 ± 0.32 mmol vs −0.76 ± 0.97 mmol, P < 0.05), TC (−0.40 ± 1.00 mmol vs −1.45 ± 2.00 mmol, P < 0.05), and LDL-C (−0.41 ± 1.05 mmol vs −0.73 ± 0.76 mmol, P < 0.05) were observed.ConclusionThe results of this study suggest that the MED/LC diet model is a good treatment for overweight PCOS patients, significantly restoring their menstrual cycle, improving their anthropometric parameters and correcting their disturbed endocrine levels, and its overall effectiveness is significantly better than the LF diet model. Therefore, this study recommends that the MED/LC diet model can be used in the clinical treatment of patients with overweight PCOS.

Correlation of Serum Homocysteine Levels and Hyperinsulinaemia with Body Mass Index in Polycystic Ovarian Syndrome.

ABSTRACTBackground:Polycystic ovary syndrome (PCOS) is one of the most common endocrinopathies affecting women in reproductive age group. The interrelationship of serum homocysteine, homoeostatic assessment of insulin resistance (HOMA-IR) and body mass index amongst overweight, obese and non-obese PCOS patients is not fully established.Aims:We aimed to study the correlation of serum homocysteine levels and hyperinsulinaemia with body mass index (BMI) in PCOS patients.Study Setting and Design:This was a case–control study in which 35 women with PCOS and 35 non-PCOS women acting as controls were enrolled.Materials and Methods:Cases were identified by Rotterdam's criteria. (IR) indices, HOMA determination and serum homocysteine levels were determined and their correlation with BMI was studied.Statistical Analysis Used:Student's t-test and analysis of variance test were used for statistical analysis. The Pearson correlation coefficient was then used to estimate the correlation.Results:On overall evaluation, a significant positive correlation of fasting insulin, HOMA-IR and serum homocysteine) was observed (P < 0.05), however, on evaluating the correlation of these markers independently in cases and controls, only fasting insulin and HOMA-IR showed a significant correlation. In a multivariate model where PCOS was considered a dependent variable with age, fasting glucose, HOMA-IR, serum homocysteine and body mass index as the independent variables, only serum homocysteine levels were found to be significantly associated with the dependent variable (odds ratio = 1.172; 95% confidence interval = 1.032–1.330).Conclusion:PCOS women had significantly higher mean fasting glucose, fasting insulin, HOMA-IR and homocysteine levels as compared to non-PCOS controls. Mean HOMA-IR, homocysteine and fasting insulin levels showed a significant incremental trend with increasing BMI category in overall evaluation as well as in cases and controls independently.

Adropin levels and its associations as a fat-burning hormone in patients with polycystic ovary syndrome: a correlational meta-analysis

Aims Adropin is a peptide hormone with potential implications in patients with polycystic ovary syndrome (PCOS). The aim of this meta-analysis was to compare the circulating (serum/plasma) and follicular fluid adropin levels between human PCOS patients and non-PCOS controls. Methods Relevant studies were retrieved by online database and manual searching. The standardized mean differences (SMDs) with 95% confidence intervals (CIs) were obtained by a random-effects meta-analysis. Meta-analysis of correlations was performed for the associations of adropin with anthropometric, lipid, insulin resistance and hormonal covariates. The funnel plot analysis with Begg’s and Egger’s tests was used for publication bias. Results A total of 9 studies were included in this meta-analysis. The results indicated that the adropin levels were significantly decreased in PCOS patients as compared to non-PCOS controls (SMD = −1.87, 95% CI = −2.55 to −1.18, p < .0001). This decrease was more evident in overweight PCOS patients than their normoweight counterparts (SMD = −0.55, 95% CI = −0.80 to −0.30, p < .0001). A one-study leave-out sensitivity analysis indicated that no single study had a significant influence on the overall outcome, suggesting the robustness of this meta-analysis. There were significant associations of decreased adropin levels with the body mass index, dyslipidemia and insulin resistance in PCOS. Conclusion Adropin levels are significantly reduced in PCOS patients compared to controls, and this decrease was more evident in overweight PCOS patients.

The relationship between glomerular filtration rate, and metabolic and inflammatory parameters in obese and non-obese patients with polycystic ovary syndrome

AimTo investigate the relationship between glomerular filtration rates (GFR), and homeostasis model assesment of insulin resistance (HOMA-IR), C-reactive protein (CRP) and neutrophil to lymphocyte ratio (NLR) in patients with polycystic ovary syndrome (PCOS). Material and methodsThirty-one overweight and obese PCOS patients with body mass index (BMI)≥25kg/m2 and 25 non-obese PCOS patients with BMI<25kg/m2 were included into patients’ group, while 23 overweight and obese, and 25 non-obese age-and BMI-matched healthy individuals (aged between 18 and 40 years), were enrolled as controls. Levels of serum creatinine, glucose, insulin, CRP, and complete blood count were measured. eGFR, HOMA-IR and NLR were also calculated. ResultsIn PCOS group, HOMA-IR (p=0.001), CRP (p=0.025) and waist hip ratio (WHR) (p=0.011) were higher than controls. In obese PCOS sub-group, HOMA-IR (p=0.004) and WHR (p=0.002) were higher than obese controls. In non-obese PCOS sub-group, HOMA-IR (p=0.001) were higher than non-obese controls. In obese PCOS sub-group; HOMA-IR (p=0.001) and CRP (p=0.001) levels were significantly higher than non-obese PCOS sub-group. In terms of other parameters, no significant difference was found between the groups. The analysis showed a negative correlation between GFR, and BMI and HOMA-IR in PCOS group, between GFR, WHR and insulin levels in obese PCOS sub-group, and between BMI, and HOMA-IR and NLR in non-obese PCOS sub-group. ConclusionAlthough HOMA-IR and CRP were higher in PCOS group, there was no difference in NLR and GFR levels between those with PCOS and controls.

In obese PCOS sub-group; HOMA-IR (p=0.001) and CRP (p=0.001) levels were significantly higher than non-obese PCOS sub-group. In terms of other parameters, no significant difference was found between the groups. The analysis showed a negative correlation between GFR, and BMI and HOMA-IR in PCOS group, between GFR, WHR and insulin levels in obese PCOS sub-group, and between BMI, and HOMA-IR and NLR in non-obese PCOS sub-group. ConclusionAlthough HOMA-IR and CRP were higher in PCOS group, there was no difference in NLR and GFR levels between those with PCOS and controls.

Effect of d-chiro-inositol and alpha-lipoic acid combination on COH outcomes in overweight/obese PCOS women

Insulin resistance (IR) plays a central role in the onset of polycystic ovary syndrome (PCOS). Insulin so insulin-sensitizing like inositols have been proposed as first line therapy. Among them d-chiro-inositol (DCI) seems to improve glucose metabolism and to increase ovulation frequency. Other studies have demonstrated that alpha-lipoic acid (ALA), with its antioxidant role, can also improve endocrine and metabolic profile of PCOS patients especially with familial diabetes. This a retrospective observational study with the aim to evaluate possible advantages of an integrative preparation combining DCI 500 mg and ALA 300 mg in overweight/obese PCOS patients with or without diabetic relatives who underwent IVF. Twenty PCOS patients who were taking the integrative preparation underwent controlled ovarian hyperstimulation in our center. The group with diabetic relatives tended to have a lower dose of gonadotropin, shorter stimulation days, higher number of MII oocytes, and higher number of fertilized oocytes. A combined regimen of DCI and ALA could be an interesting strategy in overweight PCOS patients with familial diabetes underwent ART.

IL-18 and IL-18 binding protein concentration in ovarian follicular fluid of women with unexplained infertility to PCOS during in vitro fertilization

The correlation between the concentration of interleukin (IL) 18 in follicular fluid and the pathogenesis of Polycystic Ovary Syndrome (PCOS) is unclear. Therefore, we tested the IL-18 and IL-18 binding protein (IL-18BP) levels in follicular fluid (FF) and serum in PCOS women undergoing reproductive measures and to explore their possibly correlation with PCOS. Serum and pooled follicular fluid levels of IL-18, IL-18BP and IL-18/IL-18BP ratios were evaluated in sixty patients with PCOS and sixty women with unexplained infertility undergoing in vitro fertilization. The FF IL-18 levels were increased in PCOS group than the CON group (p < 0.01), and the IL-18 levels were significantly higher in the FF than in serum in PCOS group. Furthermore, the elevated FF IL-18 levels have no correlation with the serum IL-18 levels. Additionally, the expression of IL-18 in the follicular fluid of the overweight PCOS patients was increased compared to the normal weight PCOS patients, while in the overweight patients, FF IL-18 was significantly higher in the PCOS group than in the control group. The FF IL-18 and IL-18BP may have a local involvement in the pathogenesis of PCOS. The PCOS itself and overweight will aggravate the local inflammatory response in the ovary. Further studies are needed to elucidate this issue.

A prospective randomized comparative study of comprehensive intervention using Orlistat to reduce visceral fat of overweight or obese PCOS patients

Objectives: To investigate the effect of comprehensive intervention using Orlistat to reduce visceral fat and total body fat in overweight or obese patients with polycystic ovary syndrome (PCOS)

The serum level of irisin, but not asprosin, is abnormal in polycystic ovary syndrome patients

Polycystic ovary syndrome (PCOS) is a disorder characterized by hyperandrogenism, oligo- or anovulation, and/or polycystic ovary. It frequently presents with dyslipidemia and insulin resistance. Recent studies have shown that the white adipose tissue-derived asprosin is elevated in humans with insulin resistance. Because many PCOS patients have a propensity to develop dyslipidemia and/or insulin resistance, asprosin metabolism could be dysregulated in PCOS patients. Accordingly, we investigated serum levels of asprosin, irisin, GIP, androgens, LH, glucose, insulin, and lipids as well as HOMA-IR, QUICKI and ISI Matsuda in a cohort of 444 PCOS patients and 156 controls. Patients were stratified based on metabolic syndrome risk factors (ATPIII [+] and [−] groups), or BMI (overweight and lean groups). The irisin level was significantly correlated with body weight, SBP, DBP, Ferriman–Gallwey score, and levels of TSH, triglycerides, glucose and insulin in the overall population, and was elevated in ATPIII(+) and overweight PCOS patients compared to corresponding controls. By contrast, asprosin levels in PCOS, ATPIII(+), or overweight patients were similar to those of corresponding controls. This finding indicated that the regulation of irisin, but not asprosin, metabolism is abnormal in PCOS patients, and this metabolic characteristic is distinctly different from that of diabetes patients.

The effectiveness of metformin, oral contraceptives, and lifestyle modification in improving the metabolism of overweight women with polycystic ovary syndrome: a network meta-analysis.

We designed a network meta-analysis that investigated relatively different interventions that included the effects of metformin, oral contraceptives, and lifestyle modification on the metabolic parameters of patients with polycystic ovary syndrome. In addition, we searched for eligible interventions that improved the metabolism of glucose and lipids. We searched the PubMed, EMBASE, and Cochrane Central databases from inception to May 2018. Publication types that were categorized as randomized controlled trials met our inclusion criteria. The main outcome included the homeostasis model assessment of insulin resistance, total cholesterol, low-density lipoprotein cholesterol, and total triglycerides. We performed both a pairwise meta-analysis and a network meta-analysis to evaluate the mean difference value and 95% credibility intervals, and we calculated the surface cumulative rank curve. There were a total of 12 kinds of interventions: metformin, 2 mg cyproterone acetate plus 0.05 mg ethinylestradiol (EE/CA), 0.15 mg desogestrel plus 0.03 mg ethinylestradiol (EE/DSG), and 3 mg drospirenone plus 0.03 mg ethinylestradiol (EE/DRSP), lifestyle, exercise, diet, metformin + lifestyle, metformin + diet, EE/CA + lifestyle, metformin + EE/CA, and EE/DRSP + lifestyle from the 20 eligible RCTs that were included in this study. Our meta-analysis results showed that metformin + lifestyle (MD = -2.04, 95% CrI = -3.64 to -0.41), EE/CA + lifestyle (MD = -2.23, 95% CrI = -4.11 to -0.35), and EE/DRSP + lifestyle (MD = -2.59, 95% CrI = -4.66 to -0.50) resulted in lower in the levels of total cholesterol. Women treated with metformin + lifestyle (MD = -1.82, 95% CrI = -2.88 to -0.79), EE/CA + lifestyle (MD = -2.25, 95% CrI = -3.58 to -1.08), or EE/DRSP + lifestyle (MD = -2.29, 95% CrI = -3.69 to -1.07) exhibited significantly lower low-density lipoprotein cholesterol when compared with the placebo group. There was no significant difference between any of the interventions compared with a placebo in the levels of homeostasis model assessment of insulin resistance and total triglycerides. The surface cumulative rank curve revealed that metformin + lifestyle might be the best intervention with respect to the improvement of the homeostasis model of assessment insulin resistance and EE/DRSP + lifestyle appeared to be the best intervention for the reduction of total cholesterol and low-density lipoprotein cholesterol. Moreover, the metformin + diet intervention was more effective in reducing the level of total triglycerides. For overweight polycystic ovary syndrome patients, our evidence revealed that EE/CA and EE/SRSP combined with metformin or lifestyle changes can reduce the adverse effects on glucose and lipid metabolism of the use of oral contraceptive agents alone. Conventional PCOS treatments, such as metformin, EE/CA, and EE/DRSP, combined with lifestyle control can be particularly effective in improving the homeostasis model assessment of insulin resistance and lipid metabolism.
