Abstract
Polycystic ovary syndrome (PCOS), is a health problem observed in women of reproductive age. Different diets, physical activity recommendations and lifestyle changes can be effective in dealing with the symptoms of PCOS. Nutrition is indeed an essential part of the treatment of the disease as it directly affects body weight loss, insulin resistance, lipid profile, hormones, and dermatological complaints such as acne. Polyphenols, simply classified as flavonoids and non-flavonoids, are bioactive components found in plant-based foods. The most common polyphenols in the diet are flavanols, flavonols, flavanone, anthocyanins. In particular, polyphenols which are compounds naturally found in foods, have antioxidant, anticancer, anti-inflammatory, antimutagenic benefits along with many other ones. In the treatment of PCOS, polyphenols may help reduce the symptoms, improve insulin resistance and poor lipid profile, and cure hormonal disorders. It has been reported that polyphenols are influential in menstrual cycle disorders and enable a decrease in body weight, hyperandrogenism, estrogen, testosterone, luteinizing hormone (LH)/follicle stimulating hormone (FSH) ratios and LH. For adequate daily intake of polyphenols, which are found in high amounts in fruits and vegetables, at least 5 portions of fruits and vegetables should be consumed in addition to a healthy nutrition pattern. In this review, the effects of various polyphenols on polycystic ovary syndrome are discussed.

Ann Med Surg (Lond) 2024; 86:3378-3384. [PMID: 38846853 PMCID: PMC11152844 DOI: 10.1097/ms9.0000000000001732] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Accepted: 01/08/2024] [Indexed: 06/09/2024] Open
Abstract
Objective Infertility and the pathogenesis of polycystic ovarian syndrome (PCOS) are both influenced by insulin resistance and dyslipidemia. Presumably, adding coenzyme Q10 (CoQ10) to these patients' diets will be beneficial. Therefore, this study aimed to examine the effects of CoQ10 supplementation on metabolic profiles in women candidates for in-vitro fertilization (IVF). Trial design and methods For this randomized, double-blinded, parallel, placebo-controlled clinical experiment, 40 PCOS-positive infertile women who were IVF candidates were included. They ranged in age from 18 to 40. The 20 participants in the two intervention groups received either CoQ10 or a placebo for 8 weeks. The expression of glucose transporter 1 (GLUT-1), peroxisome proliferator-activated receptor gamma (PPAR-γ), low-density lipoprotein receptor (LDLR), as well as metabolic profiles such as insulin metabolism and lipid profiles were evaluated. Quantitative RT-PCR determined the expression of GLUT-1, PPAR-γ, and LDLR on peripheral blood mononuclear cells. Lipid profiles and fasting glucose were assessed using enzymatic kits, and insulin was determined using Elisa kit. Results In comparison to the placebo, CoQ10 supplementation significantly reduced blood insulin levels (-0.3±1.0 vs. 0.5±0.7, P=0.01) and insulin resistance (-0.1±0.2 vs. 0.1±0.2, P=0.01), and increased PPAR-γ expression (P=0.01). In infertile PCOS patients' candidates for IVF, CoQ10 supplementation showed no appreciable impact on other metabolic profiles. Also, CoQ10 supplementation revealed no significant impact on GLUT-1 (P=0.30), or LDLR (P=0.27) expression. Within-group changes in insulin levels (P=0.01) and insulin resistance (P=0.01) showed a significant elevation in the placebo group. When we adjusted the analysis for baseline BMI, baseline values of variables, and age, our findings were not affected. Conclusions Eight weeks of CoQ10 supplementation demonstrated positive benefits on PPAR-γ expression, insulin resistance, and serum insulin in infertile PCOS women candidates for IVF.

Lee YM, Kim Y. Is Curcumin Intake Really Effective for Chronic Inflammatory Metabolic Disease? A Review of Meta-Analyses of Randomized Controlled Trials. Nutrients 2024; 16:1728. [PMID: 38892660 PMCID: PMC11174746 DOI: 10.3390/nu16111728] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2024] [Revised: 05/28/2024] [Accepted: 05/29/2024] [Indexed: 06/21/2024] Open
Abstract
This review aimed to examine the effects of curcumin on chronic inflammatory metabolic disease by extensively evaluating meta-analyses of randomized controlled trials (RCTs). We performed a literature search of meta-analyses of RCTs published in English in PubMed®/MEDLINE up to 31 July 2023. We identified 54 meta-analyses of curcumin RCTs for inflammation, antioxidant, glucose control, lipids, anthropometric parameters, blood pressure, endothelial function, depression, and cognitive function. A reduction in C-reactive protein (CRP) levels was observed in seven of ten meta-analyses of RCTs. In five of eight meta-analyses, curcumin intake significantly lowered interleukin 6 (IL-6) levels. In six of nine meta-analyses, curcumin intake significantly lowered tumor necrosis factor α (TNF-α) levels. In five of six meta-analyses, curcumin intake significantly lowered malondialdehyde (MDA) levels. In 14 of 15 meta-analyses, curcumin intake significantly reduced fasting blood glucose (FBG) levels. In 12 of 12 meta-analyses, curcumin intake significantly reduced homeostasis model assessment of insulin resistance (HOMA-IR). In seven of eight meta-analyses, curcumin intake significantly reduced glycated hemoglobin (HbA1c) levels. In eight of ten meta-analyses, curcumin intake significantly reduced insulin levels. In 14 of 19 meta-analyses, curcumin intake significantly reduced total cholesterol (TC) levels. Curcumin intake plays a protective effect on chronic inflammatory metabolic disease, possibly via improved levels of glucose homeostasis, MDA, TC, and inflammation (CRP, IL-6, TNF-α, and adiponectin). The safety and efficacy of curcumin as a natural product support the potential for the prevention and treatment of chronic inflammatory metabolic diseases.

Abstract
The nuclear factor κappa B (NF-κB) signaling plays a well-known function in inflammation and regulates a wide variety of biological processes. Low-grade chronic inflammation is gradually considered to be closely related to the pathogenesis of Polycystic ovary syndrome (PCOS). In this review, we provide an overview on the involvement of NF-κB in the progression of PCOS particularly, such as hyperandrogenemia, insulin resistance, cardiovascular diseases, and endometrial dysfunction. From a clinical perspective, progressive recognition of NF-κB pathway provides opportunities for therapeutic interventions aimed at inhibiting pathway-specific mechanisms. With the accumulation of basic experimental and clinical data, NF-κB signaling pathway was recognized as a therapeutic target. Although there have been no specific small molecule NF-κB inhibitors in PCOS, a plethora of natural and synthetic compound have emerged for the pharmacologic intervention of the pathway. The traditional herbs developed for NF-κB pathway have become increasingly popular in recent years. Abundant evidence elucidated that NF-κB inhibitors can significantly improve the symptoms of PCOS. Herein, we summarized evidence relating to how NF-κB pathway is involved in the development and progression of PCOS. Furthermore, we present an in-depth overview of NF-κB inhibitors for therapy interventions of PCOS. Taken together, the NF-κB signaling may be a futuristic treatment strategy for PCOS.

Abstract
Background and aim: A large number of recent studies have reported on the use of antioxidants in patients with polycystic ovary syndrome (PCOS). This study aimed to evaluate the antioxidant effects on PCOS. Methods: We searched PubMed, Embase, Web of Science, and The Cochrane Library to identify randomized controlled trials investigating the use of antioxidants in treating PCOS. Statistical analysis was performed using Review Manager 5.4. Stata17.0 software was used to conduct sensitivity analyses. Results: This meta-analysis included 49 articles and 62 studies. The sample comprised 1657 patients with PCOS from the antioxidant group and 1619 with PCOS from the placebo group. The meta-analysis revealed that the fasting blood glucose levels [standardized mean difference (SMD): -0.31, 95% confidence interval (CI): -0.39 to -0.22, P < 0.00001], the homeostatic model assessment of insulin resistance (SMD: -0.68, 95% CI: -0.87 to -0.50], P < 0.00001), and insulin levels (SMD: -0.68, 95% CI: -0.79 to -0.58, P < 0.00001) were significantly lower in patients with PCOS taking antioxidants than those in the placebo group. Further, total cholesterol levels (SMD: -0.38, 95% CI: -0.56 to -0.20, P < 0.001), low-density lipoprotein cholesterol levels (SMD: -0.24, 95% CI: -0.37 to -0.10, P = 0.0008), and very low-density lipoprotein levels (SMD: -0.53, 95% CI: -0.65 to -0.41, P < 0.00001) were lower in patients with PCOS taking antioxidant supplements compared with the placebo group. Total testosterone (TT) level (SMD: -0.78, 95% CI: -1.15 to -0.42, P < 0.0001), dehydroepiandrosterone level (SMD: -0.42, 95% CI: -0.58 to -0.25, P < 0.00001), and mean standard deviation modified Ferriman-Gallway (MF-G scores) (SMD: -0.63, 95% CI: -0.98 to -0.28, P = 0.0004) were lower in patients taking antioxidant supplements. C-reactive protein (CRP) levels (SMD: -0.48, 95% CI: -0.63 to -0.34, P < 0.000001), body mass index [mean difference (MD): -0.27, 95% CI: -0.50 to -0.03, P = 0.03], weight (MD: -0.73, 95% CI: -1.35 to -0.11, P = 0.02), and diastolic blood pressure (MD: -3.78, 95% CI: -6.30 to -1.26, P = 0.003) were significantly lower. Moreover, the levels of sex hormone-binding protein (SMD: 0.23, 95% CI: 0.07-0.38, P = 0.004), high-density lipoprotein cholesterol (SMD: 0.11, 95% CI: 0.01-0.20, P = 0.03), total antioxidant capacity (SMD: 0.59, 95% CI: 0.31-0.87, P < 0.0001), and quantitative insulin sensitivity index (SMD: 0.01, 95% CI: 0.01-0.02, P < 0.00001) were higher in patients with PCOS who took antioxidant supplements compared with the placebo group. Antioxidant supplements did not affect other analyzed parameters in these patients, including follicle-stimulating hormone, free androgen index, nitric oxide, glutathione, malondialdehyde, and diastolic blood pressure. Conclusions: Antioxidants are beneficial in treating PCOS. Our study might provide a new treatment strategy for patients with clinical PCOS. We hope that more high-quality studies evaluating the effects of antioxidants on patients with PCOS will be conducted in the future.

Abstract
Background Prior studies have reported that curcumin is inversely associated with reduced markers of atherosclerosis risk, including carotid intima-media thickness (CIMT). This study was designed to assess the effects of curcumin on CIMT and pulse wave velocity (PWV) in diabetic hemodialysis (HD) patients. Methods This randomized, double-blinded, placebo-controlled trial was conducted on 39 diabetic HD patients. People were assigned to receive curcumin or placebo (starch) for 24 weeks. Individuals in the curcumin group (n = 26) received 80 mg/day. CIMT and PWV levels were taken at baseline and after 24 weeks of intervention. Results After 24 weeks of intervention, curcumin intake did not affect mean levels of left (P = 0.83) and right (P = 0.47) CIMT and maximum levels of left (P = 0.84) and right (P = 0.11) CIMT, and PWV (P = 0.12) compared to the placebo. Furthermore, within-group difference demonstrated a significant reduction in mean levels of PWV (P = 0.01) in the curcumin group. We did not observe any significant change in C-reactive protein (CRP) concentrations after curcumin intake (P = 0.69). Conclusions Curcumin intake did not affect mean levels of left and right CIMT and maximum levels of left and right CIMT, PWV, and CRP levels compared to the placebo. Additionally, within-group difference demonstrated a significant reduction in mean levels of PWV in the curcumin group.This trial was registered at www.irct.ir as http://www.irct.ir: IRCT20200527047584N1.

Abstract
Lamotrigine (LTG) is an antiepileptic drug with possible adverse effects on the female reproductive system. Curcumin was declared to improve ovarian performance. Therefore, this study aimed to clarify ovulatory dysfunction (OD) associated with LTG and the role of curcumin in ameliorating this dysfunction. Adult female Wister albino rats were assigned into four groups: negative control (received saline), positive control (received curcumin only), LTG, and LTG with curcumin groups. Drugs were administered for 90 days. The hormonal profile, including testosterone, estrogen, progesterone, luteinizing hormone, and follicle-stimulating hormone, in addition to the lipid profile and glycemic analysis, were tested. Oxidative stress biomarkers analysis in the ovaries and uterus and peroxisome proliferator-activated receptor-γ (PPAR-γ) gene expression were also included. Histopathological examination of ovarian and uterine tissues and immunohistochemical studies were also performed. Curcumin could improve the OD related to chronic LTG intake. That was proved by the normalization of the hormonal profile, glycemic control, lipidemic status, oxidative stress markers, and PPAR-γ gene expression. The histopathological and immunohistochemical examination of ovarian and uterine tissues revealed an improvement after curcumin administration. The results describe an obvious deterioration in ovarian performance with LTG through the effect on lipidemic status, PPAR-γ gene, and creating an oxidative stress condition in the ovaries of chronic users, with a prominent improvement with curcumin addition to the treatment protocol.

Abstract
Copper (Cu) is an essential micronutrient for the correct development of eukaryotic organisms. This metal plays a key role in many cellular and physiological activities, including enzymatic activity, oxygen transport, and cell signaling. Although the redox activity of Cu is crucial for enzymatic reactions, this property also makes it potentially toxic when found at high levels. Due to this dual action of Cu, highly regulated mechanisms are necessary to prevent both the deficiency and the accumulation of this metal since its dyshomeostasis may favor the development of multiple diseases, such as Menkes' and Wilson's diseases, neurodegenerative diseases, diabetes mellitus, and cancer. As the relationship between Cu and cancer has been the most studied, we analyze how this metal can affect three fundamental processes for tumor progression: cell proliferation, angiogenesis, and metastasis. Gynecological diseases are characterized by high prevalence, morbidity, and mortality, depending on the case, and mainly include benign and malignant tumors. The cellular processes that promote their progression are affected by Cu, and the mechanisms that occur may be similar. We analyze the crosstalk between Cu deregulation and gynecological diseases, focusing on therapeutic strategies derived from this metal.

Effects of curcumin/turmeric supplementation on glycemic indices in adults: A grade-assessed systematic review and dose-response meta-analysis of randomized controlled trials. Diabetes Metab Syndr 2023; 17:102855. [PMID: 37748368 DOI: 10.1016/j.dsx.2023.102855] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/26/2022] [Revised: 09/07/2023] [Accepted: 09/10/2023] [Indexed: 09/27/2023]
Abstract
INTRODUCTION Glycemic control is of utmost importance both as a preventive measure in individuals at risk of diabetes and in the management of patients with disturbed glycemia. Turmeric/curcumin has been extensively studied in this field. In the present systematic review and meta-analysis, we aimed at investigating the impact of turmeric/curcumin supplementation on glycemic control. METHODS Major online databases (PubMed, Scopus, Web of Science, Cochrane Library and Google Scholar) were systematically searched from inception up to October 2022. Relevant randomized controlled trials (RCTs) meeting our eligible criteria were included. Weighted mean differences (WMDs) with confidence intervals (CIs) were expressed using a random-effect model. Subgroup analyses were conducted to find the sources of heterogeneities. To detect risk of bias in the included studies, we used the Cochrane risk-of-bias tool. The registration number was CRD42022374874. RESULTS Out of 4182 articles retrieved from the initial search, 59 RCTs were included. Our findings suggested that turmeric/curcumin supplementation was significantly effective in improving fasting blood sugar (WMD: 4.60 mg/dl; 95% CI: 5.55, -3.66), fasting insulin levels (WMD: 0.87 μIU/ml; 95% CI: 1.46, -0.27), hemoglobin A1c (HbA1c) (WMD: 0.32%; 95% CI: 0.45, -0.19), and homeostatic model assessment of insulin resistance (HOMA-IR) (WMD: 0.33; 95% CI: 0.43, -0.22). CONCLUSION Our results indicate that turmeric/curcumin supplementation can be considered as a complementary method in the management of disturbed glycemia.

Abstract
PURPOSE OF REVIEW Polycystic ovarian syndrome (PCOS) is a common endocrine disease characterized by ovulatory dysfunction, hyperandrogenism, and polycystic ovarian morphology and causing various reproductive, metabolic, cardiovascular, oncological, and psychological complications. Recent meta-analyses and systemic reviews showed that PCOS increases the risk factor for various cardio-metabolic complications like insulin resistance, type II diabetes mellitus, dyslipidemia, metabolic syndrome, hypertension, and endothelial dysfunction. In addition to these, it was suggested that chronic low-grade inflammation and oxidative stress are the underlying mechanisms of PCOS-mediated metabolic consequences and might trigger cardio-metabolic risk in women with PCOS. At this point, there is substantial evidence to suggest that various non-nutrient food components modulate cardio-metabolic health together with inflammation and oxidative stress. RECENT FINDINGS Increasing the intake of dietary polyphenols might reduce oxidative stress and inflammation and thus alleviate the risk of metabolic, endothelial, and cardiovascular disorders. Nowadays, there are an increasing number of studies related to the effects of dietary polyphenols on PCOS and its accompanying cardio-metabolic disturbances. Currently, there is a cumulative number of studies connected to the effects of dietary polyphenols on PCOS and accompanying cardio-metabolic disturbances. However, there is a lack of knowledge in combining the probable mechanisms of dietary polyphenols on PCOS and related cardio-metabolic consequences. Thus, the effects of dietary polyphenols on PCOS and accompanying cardio-metabolic disturbances need to be discussed and evaluated with underlying mechanisms. Consequently, this review was written to reveal the potential effects of dietary polyphenols on PCOS and related metabolic and cardiovascular risk factors in all their aspects.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:6534. [PMID: 37569074 PMCID: PMC10418663 DOI: 10.3390/ijerph20156534] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/18/2023] [Revised: 07/19/2023] [Accepted: 07/27/2023] [Indexed: 08/13/2023]
Abstract
Polycystic ovarian syndrome (PCOS) is an endocrine condition that impacts nutritional status, metabolic, and hormonal function in females of reproductive age. This condition is associated with increased androgen production (hyperandrogenism) and decreased insulin sensitivity, which often leads to insulin resistance and hyperinsulinemia. This increase in androgen production and insulin resistance is strongly associated with a high incidence of obesity, type-2 diabetes mellitus (T2DM), cardiovascular diseases (CVD), and certain types of gonad-related cancers among females who suffer from this condition. As research continues to grow, it has been demonstrated that PCOS is a complex condition, and some of its characteristics vary among the females that have this disorder. However, it has been suggested that oxidative stress and low-grade chronic inflammation could play an important role in the development of PCOS. Current evidence suggest that phytochemicals could potentially help with weight-loss by reducing oxidative stress and low-grade inflammation, as well as aid in metabolic and hormonal regulation due to their antioxidant properties. Some of the bioactive compounds found in plants that have shown positive effects in the attenuation of PCOS include flavonoids, polyphenols, phytoestrogen, and polyunsaturated fatty acids (PUFAs). Thus, a review of the current literature published on PCOS and phytochemicals was conducted in PubMed, Google Scholar, and the Academy of Nutrition and Dietetics databases for articles published between 2013 and 2023 with a study duration of 1 to 3 months and adequate sample sizes. The main purpose of this review of literature was to investigate the metabolic effects of phytochemical compounds and phytochemical-rich diets on females with PCOS by comparing the results of several randomized clinical trials.

Abstract
Polycystic ovary syndrome (PCOS) is a common hormonal disorder among women (4%-20%) when the ovaries create abnormally high levels of androgens, the male sex hormones that are typically present in women in trace amounts. The primary characteristics of PCOS include oxidative stress, inflammation, hyperglycemia, hyperlipidemia, hyperandrogenism, and insulin resistance. Generally, metformin, spironolactone, eflornithine and oral contraceptives are used to treat PCOS, despite their several side effects. Therefore, finding a potential candidate for treating PCOS is necessary. Curcumin is a major active natural polyphenolic compound derived from turmeric (Curcuma longa). A substantial number of studies have shown that curcumin has anti-inflammatory, anti-oxidative stress, antibacterial, and anti-apoptotic activities. In addition, curcumin reduces hyperglycemia, hyperlipidemia, hyperandrogenism, and insulin resistance in various conditions, including PCOS. The review highlighted the therapeutic aspects of curcumin against the pathophysiology of PCOS. We also offer a hypothesis to improve the development of medicines based on curcumin against PCOS.

Abstract
INTRODUCTION Numerous approaches have been assigned to treat dyslipidemia (DLP). Turmeric/curcumin have been widely investigated with this regard. In the current study, we explored the effect of curcumin/turmeric supplementation on lipid profile. METHODS Online databases were searched up to October 2022. The outcomes included triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-c), high-density lipoprotein cholesterol (HDL-c), apolipoprotein B (Apo-B), and apolipoprotein A (Apo-A). We used the Cochrane quality assessment tool to evaluate the risk of bias. The effect sizes were estimated as weighted mean difference (WMD) and 95% confidence intervals (CIs). RESULTS Out of 4182 articles retrieved from the initial search, 64 randomized clinical trials (RCTs) were included in the study. Between-study heterogeneity was significant. Meta-analysis showed that turmeric/curcumin supplementation exerts statistically significant improvements on blood levels of TC (WMD = -3.99mg/dL; 95% CI = -5.33, -2.65), TG (WMD = -6.69mg/dL; 95% CI = -7.93, -5.45), LDL-c (WMD = -4.89mg/dL; 95% CI = -5.92, -3.87), and HDL-c (WMD = 1.80mg/dL; 95% CI = 1.43, 2.17). However, turmeric/curcumin supplementation was not associated with improvements in blood levels of Apo-A or Apo-B. The studies did not thoroughly address the issues of potency, purity, or consumption with other foods. CONCLUSION Turmeric/curcumin supplementation seems to be effective in improving blood levels of TC, TG, LDL-c, and HDL-c; but may not be capable of improving their pertinent apolipoproteins. Since the evidence was assessed to be low and very low concerning the outcomes, these findings should be dealt with caution.

Abstract
The past couple of decades in particular have seen a rapid increase in the prevalence of type 2 diabetes mellitus (T2DM), a debilitating metabolic disorder characterised by insulin resistance. The insufficient efficacy of current management strategies for insulin resistance calls for additional therapeutic options. The preponderance of evidence suggests potential beneficial effects of curcumin on insulin resistance, while modern science provides a scientific basis for its potential applications against the disease. Curcumin combats insulin resistance by increasing the levels of circulating irisin and adiponectin, activating PPARγ, suppressing Notch1 signalling, and regulating SREBP target genes, among others. In this review, we bring together the diverse areas pertaining to our current understanding of the potential benefits of curcumin on insulin resistance, associated mechanistic insights, and new therapeutic possibilities. Teaser: Current approaches to manage insulin resistance are not highly efficacious, which necessitates additional therapeutic options; curcumin combats insulin resistance by improving the levels of circulating irisin and adiponectin, upregulating and activating PPARγ, and suppressing Notch‑1 signalling.

Abstract
Polycystic ovary syndrome (PCOS) is a reproductive endocrine disease characterized by menstrual disorders, infertility, and obesity, often accompanied by insulin resistance and metabolic disorders. The pathogenesis of PCOS is relatively complex and has a certain relationship with endocrine disorders. The increase of androgen and luteinizing hormone (LH) is the main cause of a series of symptoms. Traditional Chinese medicine (TCM) has obvious advantages and significant curative effects in the treatment of this disease. It can effectively reduce the insulin level of PCOS patients, regulate lipid metabolism, and increase ovulation rate and pregnancy rate and has fewer side effects. This article reviews the efficacy and safety of Chinese herbs and other TCM (such as acupuncture) in the treatment of PCOS and its complications in recent years, as well as the effect and mechanism on cellular endocrine, in order to provide a new clinical idea for the treatment of PCOS.

Abstract
An increase in life expectancy leads to a greater impact of chronic non-communicable diseases. This is even more remarkable in elder populations, to whom these become main determinants of health status, affecting mental and physical health, quality of life, and autonomy. Disease appearance is closely related to the levels of cellular oxidation, pointing out the importance of including foods in one's diet that can prevent oxidative stress. Previous studies and clinical data suggest that some plant-based products can slow and reduce the cellular degradation associated with aging and age-related diseases. Many plants from one family present several applications that range from the food to the pharmaceutical industry due to their characteristic flavor and scents. The Zingiberaceae family, which includes cardamom, turmeric, and ginger, has bioactive compounds with antioxidant activities. They also have anti-inflammatory, antimicrobial, anticancer, and antiemetic activities and properties that help prevent cardiovascular and neurodegenerative diseases. These products are abundant sources of chemical substances, such as alkaloids, carbohydrates, proteins, phenolic acids, flavonoids, and diarylheptanoids. The main bioactive compounds found in this family (cardamom, turmeric, and ginger) are 1,8-cineole, α-terpinyl acetate, β-turmerone, and α-zingiberene. The present review gathers evidence surrounding the effects of dietary intake of extracts of the Zingiberaceae family and their underlying mechanisms of action. These extracts could be an adjuvant treatment for oxidative-stress-related pathologies. However, the bioavailability of these compounds needs to be optimized, and further research is needed to determine appropriate concentrations and their antioxidant effects in the body.

Abstract
Polycystic ovary syndrome (PCOS) constitutes the most common endocrine disorder in women of reproductive age. Patients usually suffer from severe menstrual irregularities, skin conditions, and insulin resistance-associated health conditions. Peroxisome proliferator-activated receptors (PPARs) are nuclear receptor proteins that regulate gene expression. In order to investigate the role of PPARs in the pathophysiology of PCOS, we conducted a literature review using the MEDLINE and LIVIVO databases and were able to identify 74 relevant studies published between 2003 and 2023. Different study groups reached contradictory conclusions in terms of PPAR expression in PCOS. Interestingly, numerous natural agents were found to represent a novel, potent anti-PCOS treatment alternatives. In conclusion, PPARs seem to play a significant role in PCOS.

Abstract
Turmeric (Curcuma longa) has been used for thousands of years for the prevention and treatment of various chronic diseases. Curcumin is just one of >200 ingredients in turmeric. Almost 7000 scientific papers on turmeric and almost 20,000 on curcumin have been published in PubMed. Scientific reports based on cell culture or animal studies are often not reproducible in humans. Therefore, human clinical trials are the best indicators for the prevention and treatment of a disease using a given agent/drug. Herein, we conducted an extensive literature survey on PubMed and Scopus following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The keywords "turmeric and clinical trials" and "curcumin and clinical trials" were considered for data mining. A total of 148 references were found to be relevant for the key term "turmeric and clinical trials", of which 70 were common in both PubMed and Scopus, 44 were unique to PubMed, and 34 were unique to Scopus. Similarly, for the search term "curcumin and clinical trials", 440 references were found to be relevant, of which 70 were unique to PubMed, 110 were unique to Scopus, and 260 were common to both databases. These studies show that the golden spice has enormous health and medicinal benefits for humans. This Review will extract and summarize the lessons learned about turmeric and curcumin in the prevention and treatment of chronic diseases based on clinical trials.

Abstract
BACKGROUND Curcumin supplementation may promote weight loss and ameliorate obesity-related complications through its antioxidative and anti-inflammatory properties. OBJECTIVE An umbrella review and updated meta-analysis of randomized controlled trials (RCTs) was conducted to evaluate the effect of curcumin supplementation on anthropometric indices. METHODS Systematic reviews and meta-analyses (SRMAs) of RCTs were identified from electronic databases (Medline, Scopus, Cochrane, and Google Scholar) up to 31 March, 2022, without language restriction. SRMAs were included if they assessed curcumin supplementation on any of the following: BMI, body weight (BW), or waist circumference (WC). Subgroup analyses were performed, stratifying by patient types, severity of obesity, and curcumin formula. The study protocol was a priori registered. RESULTS From an umbrella review, 14 SRMAs with 39 individual RCTs were included with a high degree of overlap. In addition, searching was updated from the last search of included SRMAs in April 2021 up to 31 March, 2022, and we found 11 additional RCTs, bringing the total up to 50 RCTs included in the updated meta-analyses. Of these, 21 RCTs were deemed of high risk of bias. Curcumin supplementation significantly reduced BMI, BW, and WC with mean differences (MDs) of -0.24 kg/m2 (95% CI: -0.32, -0.16 kg/m2), -0.59 kg (95% CI: -0.81, -0.36 kg), and -1.32 cm (95% CI: -1.95, -0.69 cm), respectively. The bioavailability-enhanced form reduced BMI, BWs, and WC more, with MDs of -0.26 kg/m2 (95% CI: -0.38, -0.13 kg/m2), -0.80 kg (95% CI: -1.38, -0.23 kg) and -1.41 cm (95% CI: -2.24, -0.58 cm), respectively. Significant effects were also seen in subgroups of patients, especially in adults with obesity and diabetes. CONCLUSIONS Curcumin supplementation significantly reduces anthropometric indices, and bioavailability-enhanced formulas are preferred. Augmenting curcumin supplement with lifestyle modification should be an option for weight reduction. This trial was registered at PROSPERO as CRD42022321112 (https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42022321112).

Effects of curcumin/turmeric supplementation on obesity indices and adipokines in adults: A grade-assessed systematic review and dose-response meta-analysis of randomized controlled trials. Phytother Res 2023; 37:1703-1728. [PMID: 36882287 DOI: 10.1002/ptr.7800] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Revised: 02/11/2023] [Accepted: 02/22/2023] [Indexed: 03/09/2023]
Abstract
In the present study, we explored the effect of curcumin/turmeric supplementation on anthropometric indices of obesity, leptin, and adiponectin. We searched PubMed, Scopus, Web of Science, Cochrane Library, and Google Scholar up to August 2022. Randomized clinical trials (RCTs) investigating the impact of curcumin/turmeric on obesity indices and adipokines were included. We applied the Cochrane quality assessment tool to evaluate the risk of bias. The registration number is CRD42022350946. Sixty eligible RCTs, with a total sample size of 3691 individuals were included for quantitative analysis. We found that supplementation with curcumin/turmeric significantly reduced body weight (WMD: -0.82 kg, 95% CI: -1.30, -0.35; p = 0.001), body mass index (WMD: -0.30 kg/m2 , 95% CI: -0.53, -0.06, p = 0.013), waist circumference (WMD: -1.31 cm, 95% CI: -1.94, -0.69, p < 0.001), body fat percentage (WMD: -0.88%, 95% CI: -1.51, -0.25, p = 0.007), leptin (WMD = -4.46 ng/mL; 95% CI: -6.70, -2.21, p < 0.001), and increased adiponectin (WMD = 2.48 μg/mL; 95% CI: 1.34, 3.62, p < 0.001). Overall, our study shows that supplementation with curcumin/turmeric significantly improves anthropometric indices of obesity and adiposity-related adipokines (leptin and adiponectin). However, due to high between-studies heterogeneity, we should interpret the results with caution.

Abstract
Medicinal properties of turmeric (Curcuma longa L.), a plant used for centuries as an anti-inflammatory, are attributed to its polyphenolic curcuminoids, where curcumin predominates. Although "curcumin" supplements are a top-selling botanical with promising pre-clinical effects, questions remain regarding biological activity in humans. To address this, a scoping review was conducted to assess human clinical trials reporting oral curcumin effects on disease outcomes. Eight databases were searched using established guidelines, yielding 389 citations (from 9528 initial) that met inclusion criteria. Half focused on obesity-associated metabolic disorders (29%) or musculoskeletal disorders (17%), where inflammation is a key driver, and beneficial effects on clinical outcomes and/or biomarkers were reported for most citations (75%) in studies that were primarily double-blind, randomized, and placebo-controlled trials (77%, D-RCT). Citations for the next most studied disease categories (neurocognitive [11%] or gastrointestinal disorders [10%], or cancer [9%]), were far fewer in number and yielded mixed results depending on study quality and condition studied. Although additional research is needed, including systematic evaluation of diverse curcumin formulations and doses in larger D-RCT studies, the preponderance of current evidence for several highly studied diseases (e.g., metabolic syndrome, osteoarthritis), which are also clinically common, are suggestive of clinical benefits.

Abstract
BACKGROUND Considering the high prevalence of polycystic ovary syndrome (PCOS) in women of reproductive age and the metabolic disorders associated with it, this study was conducted to determine the effects of curcumin on metabolic indices and androgen level (primary outcomes), and menstruation characteristics, and hirsutism (secondary outcomes) in women with PCOS. METHODS This triple-blind randomized controlled trial was conducted on women with PCOS who visited the health centers at Eslamshahr County (Tehran Province-Iran) from 2020 to 2022. The participants were allocated into two groups (curcumin and placebo) using block randomization method. The treatment group received two 500 mg edible curcumin tablets together at the same time per day for twelve weeks while the control group received placebo tablets similar to curcumin. Biochemical parameters such as Fasting Blood Insulin (FBI), Fasting Blood Sugar (FBS), triglyceride, total cholesterol, Low Density Lipoprotein- cholesterol (LDL-C), High Density Lipoprotein- cholesterol (HDL-C) were measured before intervention and then 3 months after the intervention. Sex Hormone Binding Globulin (SHBG) and testosterone serum levels were measured 3 months after the intervention. Questionnaires regarding the menstrual cycle characteristics and the Ferriman-Gallwey score were also filled for evaluating hirsutism before the intervention as well as 3 months after the intervention. The independent t-test, Mann-Whitney U test, and ANCOVA were used to analyze the data. RESULTS There was no statistically significant difference between the two groups in terms of socio-demographic and the baseline levels of measured outcomes. After 12 weeks of intervention, the mean serum FBS levels in the curcumin group were significantly lower than in the placebo group (mean difference: 6.24; 95%confidence interval: -11.73 to -0.76; P = 0.027) but there was no significant difference between the two groups in terms of triglyceride (P = 0.351), cholesterol (P = 0.528), LDL (P = 0.064), HDL (P = 0.306), FBI (p = 0.929), SHBG (p = 0.682), and testosterone (p = 0.133) serum levels. After the intervention, amenorrhea and oligomenorrhea frequency in the curcumin group was significantly lower than in the placebo group (13% vs. 22%, P = 0.038). There was no significant difference in terms of duration of menstruation (P = 0.286) and hirsutism (P = 0.630) between the two groups. CONCLUSION Curcumin decreased FBS levels and improved menstruation characteristics (amenorrhea, oligomenorrhea, and menstrual irregularities) in women with PCOS but did not affect other metabolic, hormonal, and hirsutism indices. More studies using a larger sample size are required for a definitive conclusion.

Abstract
This systematic review aimed to evaluate the efficacy of phytochemicals on lipid parameters in patients with hypertriglyceridemia (HTG). A comprehensive search was performed in PubMed/Medline, Scopus, ISI Web of Science, and Google Scholar from inception up to October 2021 to recognize randomized controlled trials (RCTs) assessing the effects of phytochemicals on lipid profiles in patients with HTG. Forty-eight RCTs including 53 arms and comprising 3,478 HTG patients met the eligibility criteria. Phytochemicals significantly reduced the serum levels of triglycerides in 32 out 53 arms, total cholesterol in 22 out of 51, low-density lipoprotein cholesterol in 21 out of 48, very low-density lipoprotein cholesterol in 1 out of 5, apolipoprotein B in 2 out of 4, and lipoprotein(a) levels in 2 out of 4 arms. Furthermore, phytochemicals supplementation increased the levels of high-density lipoprotein cholesterol in 15 out of 48 arms. In brief, phytochemicals supplementation might have beneficial effects on HTG. In most of the studies, phytochemicals had a favorable effect on at least one of the lipid parameters.

Abstract
Objective: The effect of antioxidant supplements on glucose metabolism and lipid profiles in polycystic ovary syndrome (PCOS) remains controversial. This systematic review and meta-analysis aimed to evaluate whether antioxidant supplements improve glucose metabolism and lipid profiles in women with PCOS to provide optimal nutritional supplement advice in clinical practice. Methods: The search was conducted across multiple medical databases from inception to January 1, 2022 and performed following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. A random effects model was used to calculate the overall effects. Results: Eighteen trials (1113 participants) were included. Antioxidant supplements significantly improved insulin resistance (95% CI, -0.62, -0.30; p < 0.00001; I2 =48%), fasting insulin (95% CI, -0.80, -0.44; p < 0.00001; I2 = 48%), and fasting plasma glucose (95% CI, -0.54, -0.21; p < 0.00001; I2 = 38%) in patients with PCOS. However, antioxidant supplements were found to not improve most indices of lipid profiles in PCOS except triglyceride. Conclusions: Antioxidant supplements are an effective intervention for relieving insulin resistance but do not significantly improve lipid metabolism in women with PCOS.

Abstract
Salt-induced renal metabolism dysfunction is an important mechanism of salt-sensitive hypertension. Given that the gut-liver axis is the first hit of a high-salt diet (HSD), we aimed to identify the extra-renal mechanism from hepatic metabolism and gut microbiota, and attempted to relieve the salt-induced metabolic dysfunctions by curcumin. Untargeted metabolomics analysis was performed to identify the changes in hepatic metabolic pathways, and integrated analysis was employed to reveal the relationship between hepatic metabolic dysfunction and gut microbial composition. HSD induced significant increase in fumaric acid, l-lactic acid, creatinine, l-alanine, glycine, and l-cysteine levels, and amino acids metabolism pathways associated with glycolysis were significantly altered, including alanine, aspartate, and glutamate metabolism; glycine, serine, and threonine metabolism, which were involved in the regulation of blood pressure. Integrated multi-omics analysis revealed that changes in Paraprevotella, Erysipelotrichaceae, and genera from Clostridiales are associated with metabolic disorders. Gene functional predication analysis based on 16S Ribosomal RNA sequences showed that the dysfunction in hepatic metabolism were correlated with enhanced lipopolysaccharide (LPS) biosynthesis and apoptosis in gut microbes. Curcumin (50 mg/kg/d) might reduce gut microbes-associated LPS biosynthesis and apoptosis, partially reverse metabolic dysfunction, ameliorate renal oxidative stress, and protect against salt-sensitive hypertension.

Abstract
As an important part of the human intestinal microecology, the intestinal flora is involved in a number of physiological functions of the host. Several studies have shown that imbalance of intestinal flora and its regulation of the intestinal barrier, intestinal immune response, and intestinal flora metabolites (short-chain fatty acids and bile acids) can affect the development and regression of female reproductive disorders. Herbal medicine has unique advantages in the treatment of female reproductive disorders such as polycystic ovary syndrome, endometriosis and premature ovarian insufficiency, although its mechanism of action is still unclear. Therefore, based on the role of intestinal flora in the occurrence and development of female reproduction-related diseases, the progress of research on the diversity, structure and composition of intestinal flora and its metabolites regulated by botanical drugs, Chinese herbal formulas and active ingredients of Chinese herbal medicines is reviewed, with a view to providing reference for the research on the mechanism of action of Chinese herbal medicines in the treatment of female reproductive disorders and further development of new herbal medicines.

Abstract
Objective This investigation was conducted to analyze and evaluate the impact of Chinese herbal medicine on glucolipid metabolism in women with polycystic ovary syndrome (PCOS). Methods We used manual and computer-aided search methods, and the search scopes included Chinese databases (China National Knowledge Infrastructure, Wanfang, the China Science and Technology Journal Database, and the Chinese Biomedical Literature Database) and English databases (PubMed, Embase, Web of Science, and the Cochrane Library). We searched these eight databases for randomized controlled trials investigating the effects of Chinese herbal medicine on glucolipid metabolism in women with PCOS, with the retrieval deadline being June 2021. Two reviewers screened, selected, and extracted data and verified the results independently. The NoteExpress software was used to manage and screen the literature, the risk of bias assessment tool was used to evaluate the methodological quality of the included studies, and the RevMan 5.4 software was used for meta-analysis. Results A total of 13 trials were included, including 825 patients with PCOS. Because the drugs used in the control group were different, we divided the results into two parts, with four trials using placebo and nine trials using metformin as the control. The results of the meta-analysis showed that fasting insulin (MD = −2.45, 95% CI = [−4.74, −0.17], P = 0.04), 2 h fasting plasma glucose (MD = −0.33, 95% CI = [−0.64, −0.02], P = 0.04), serum total cholesterol (MD = −0.38, 95% CI = [−0.58, −0.18], P = 0.0002), triglycerides (MD = −0.36, 95% CI = [−0.58, −0.14], P = 0.001), and low-density lipoprotein cholesterol (MD = −0.58, 95% CI = [−0.75, −0.41], P < 0.00001) were significantly improved in the Chinese herbal medicine group compared with the placebo group. In addition, compared with metformin, body mass index (MD = −1.04, 95% CI = [−1.55, −0.53], P < 0.0001), serum total cholesterol (MD = −0.27, 95% CI = [−0.46, −0.07] P = 0.007), and low-density lipoprotein cholesterol were significantly reduced (MD = −0.12, 95% CI = [−0.22, −0.02], P = 0.02) and high-density lipoprotein cholesterol (MD = 0.09, 95% CI = [0.02, 0.17], P = 0.01) was significantly improved after treatment with Chinese herbal medicine. Conclusion Compared with the placebo group, Chinese herbal medicine had positive effects on glucolipid metabolism in women with PCOS. Chinese herbal medicine had a positive effect on lipid metabolism when the control group was metformin, but no effect on glucose metabolism. These findings need to be verified in high-quality, large-sample, randomized controlled trials in the future.

Abstract
Peroxisome proliferator-activated receptors (PPARs) are members of the ligand-dependent nuclear receptor family. PPARs have attracted wide attention as pharmacologic mediators to manage multiple diseases and their underlying signaling targets. They mediate a broad range of specific biological activities and multiple organ toxicity, including cellular differentiation, metabolic syndrome, cancer, atherosclerosis, neurodegeneration, cardiovascular diseases, and inflammation related to their up/downstream signaling pathways. Consequently, several types of selective PPAR ligands, such as fibrates and thiazolidinediones (TZDs), have been approved as their pharmacological agonists. Despite these advances, the use of PPAR agonists is known to cause adverse effects in various systems. Conversely, some naturally occurring PPAR agonists, including polyunsaturated fatty acids and natural endogenous PPAR agonists curcumin and resveratrol, have been introduced as safe agonists as a result of their clinical evidence or preclinical experiments. This review focuses on research on plant-derived active ingredients (natural phytochemicals) as potential safe and promising PPAR agonists. Moreover, it provides a comprehensive review and critique of the role of phytochemicals in PPARs-related diseases and provides an understanding of phytochemical-mediated PPAR-dependent and -independent cascades. The findings of this research will help to define the functions of phytochemicals as potent PPAR pharmacological agonists in underlying disease mechanisms and their related complications.

Edible Bioactive Film with Curcumin: A Potential "Functional" Packaging? Int J Mol Sci 2022; 23:ijms23105638. [PMID: 35628450 PMCID: PMC9147907 DOI: 10.3390/ijms23105638] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Revised: 05/11/2022] [Accepted: 05/16/2022] [Indexed: 02/04/2023] Open
Abstract
Edible packaging has been developed as a biodegradable and non-toxic alternative to traditional petroleum-based food packaging. Biopolymeric edible films, in addition to their passive protective function, may also play a bioactive role as vehicles for bioactive compounds of importance to human health. In recent years, a new generation of edible food packaging has been developed to incorporate ingredients with functional potential that have beneficial effects on consumer health. Curcumin, a bioactive compound widely used as a natural dye obtained from turmeric rhizomes (Curcuma longa L.), has a broad spectrum of beneficial properties for human health, such as anti-inflammatory, anti-hypertensive, antioxidant, anti-cancer, and other activities. To demonstrate these properties, curcumin has been explored as a bioactive agent for the development of bioactive packaging, which can be referred to as functional packaging and used in food. The aim of this review was to describe the current and potential research on the development of functional-edible-films incorporating curcumin for applications such as food packaging.

Abstract
Despite continuous advances in pharmacotherapy, atherosclerotic cardiovascular disease remains the world's leading killer. Atherosclerosis relates not only to an increased level of cholesterol, but involves the development of atherosclerotic plaques, which are formed as a result of processes including inflammation and oxidative stress. Therefore, in addition to the classical risk factors for ASCVD (such as type 2 diabetes, overweight, obesity, hypertension and metabolic syndrome), residual risk factors such as inflammation and oxidative stress should also be reduced. The most important intervention in ASCVD is prevention, which includes promoting a healthy diet based on products of natural origin. Curcumin, which is often present in the diet, has been demonstrate to confer several benefits to health. It has been shown in numerous clinical trials that curcumin exhibited anti-diabetic, lipid-lowering, antihypertensive, antioxidant and anti-inflammatory effects, as well as promoting weight loss. All this means that curcumin has a comprehensive impact on the most important risk factors of ASCVD and may be a beneficial support in the treatment of these diseases. Recently, it has also been shown that curcumin may have a beneficial effect on the course of SARS-CoV-2 infection and might be helpful in the prevention of long-COVID complications. The aim of this review is to summarize the current knowledge regarding the safety and efficacy of curcumin in the prevention and treatment of cardiometabolic diseases.

Abstract
Purpose
This paper aims to assess the impact of curcumin supplementation body mass index and glycemic indices in women with polycystic ovary syndrome (PCOS).
Design/methodology/approach
A systematic search of the literature was conducted in PubMed, Scopus and ISI web of science to identify all randomized controlled trials (RCTs) published from the earliest record up to February 2021. The authors used a random-effects model to estimate pooled effect sizes.
Findings
A total of four potentially related clinical trials met the inclusion criteria which included a total of 198 participants. Random-effects meta-analysis showed significant effects of curcumin on fasting blood sugar (FBS) (−3.62 mg/dl, 95% CI [−5.65, −1.58], p-value < 0.001, I2 = 0.0%), insulin level (−1.67 µU/mL, 95% CI [−3.06, −0.28], p-value = 0.018, I2 = 0.0%) and homeostasis model of assessment insulin resistance (HOMA-IR) (−0.42, 95% CI [−0.76, −0.09], p-value < 0.01, I2 = 0.0%). No evidence of publication bias was discovered in the meta-analyses.
Originality/value
Present systematic review and meta-analysis of RCTs showed beneficial effects of curcumin consumption on FBS, insulin level and HOMA-IR in patients with PCOS. However, further large-scale studies are needed to confirm these results.

An overview of the therapeutic effects of curcumin in reproductive disorders with a focus on the antiinflammatory and immunomodulatory activities. Phytother Res 2022; 36:808-823. [PMID: 35041229 DOI: 10.1002/ptr.7360] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2021] [Revised: 12/07/2021] [Accepted: 12/08/2021] [Indexed: 12/24/2022]
Abstract
Curcumin, the polyphenolic compound obtained from turmeric, has several pharmacological properties. These properties include antioxidant, antimicrobial, anti-angiogenic, anticarcinogenic, antiinflammatory, and immunomodulatory activities. Therefore, the clinical efficacy of this substance has been largely investigated for curing numerous disorders. Based on a growing body of literature, this review aimed to investigate curcumin's molecular and clinical effects on reproduction and related disorders. Curcumin in the female reproductive system attenuates folliculogenesis, promotes apoptosis of oocytes and blastocyst, and decreases embryo implantation and survival. Curcumin at <100 mg concentration shows protective effects against testicular injury. The concentration of >250 mg of curcumin exhibits immobilizing action on sperms, and at 500 mg concentration completely blocks pregnancy. Curcumin inhibits vaginal infections, attenuates the severity of the premenstrual syndrome, ameliorates inflammatory conditions in polycystic ovary syndrome, improves preeclampsia, and prevents ectopic endometrial lesions. Taken together, curcumin, because of the numerous biological activities, low level of toxicity, and lower adverse effects compared to the synthetic drugs, could be considered as a protective agent for preserving the semen quality parameters, a contraceptive, and chemotherapeutic or chemopreventive agent, as well as an appropriate agent for the treatment of female reproductive disorders.

Curcumin in Combination with Aerobic Exercise Improves Follicular Dysfunction via Inhibition of the Hyperandrogen-Induced IRE1 α/XBP1 Endoplasmic Reticulum Stress Pathway in PCOS-Like Rats. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2022; 2021:7382900. [PMID: 34987702 PMCID: PMC8720591 DOI: 10.1155/2021/7382900] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Revised: 10/22/2021] [Accepted: 11/26/2021] [Indexed: 01/03/2023]
Abstract
Combining diet with exercise can improve health and performance. Exercise can reduce androgen excess and insulin resistance (IR) in polycystic ovary syndrome (PCOS) patients. Curcumin is also presumed to improve the follicle development disorder. Here, we investigated the effects of a combination therapy of oral intake of curcumin and exercise on hyperandrogen-induced endoplasmic reticulum (ER) stress and ovarian granulosa cell (GC) apoptosis in rats with PCOS. We generated a PCOS model via continuous dehydroepiandrosterone subcutaneous injection into the necks of Sprague Dawley rats for 35 days. PCOS-like rats then received curcumin treatment combined with aerobic (treadmill) exercise for 8 weeks. We found that compared to control rats, the ovarian tissue and ovarian GCs of hyperandrogen-induced PCOS rats showed increased levels of ER stress-related genes and proteins. Hyperandrogen-induced ovarian GC apoptosis, which was mediated by excessive ER stress and unfolded protein response (UPR) activation, could cause follicle development disorders. Both curcumin gavage and aerobic exercise improved ovarian function via inhibiting the hyperandrogen-activated ER stress IRE1α-XBP1 pathway. Dihydrotestosterone- (DHT-) induced ER stress was mitigated by curcumin/irisin or 4μ8C (an ER stress inhibitor) in primary GC culture. In this in vitro model, the strongly expressed follicular development-related genes Ar, Cyp11α1, and Cyp19α1 were also downregulated.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is a multi-factorial heterogeneous syndrome that has both adverse reproductive and metabolic implications for affected women and its management is a challenging clinical problem. Curcumin, as a phenolic compound with potent anti-inflammatory and antioxidant properties exerting positive effects on the lipid profile and insulin resistance, appears to be a valuable treatment regimen for patients with PCOS. OBJECTIVE This study aimed to evaluate the efficacy and safety of curcumin in the treatment of PCOS. METHODS Chinese databases (Chinese National Knowledge Infrastructure, China Biology Medicine Databases, VIP database, Wanfang Database, and Chinese Clinical Trial Registry) and English databases (PubMed, Web of Science, Embase, Cochrane Library, Scopus and Clinical trials) were thoroughly investigated through screening randomized controlled trials on curcumin in PCOS published from the date of inception to May 2022. Standardized data search and abstraction were conducted following the preferred reporting items for systematic reviews and meta-analysis (PRISMA) statement. Quantitative and qualitative analyses were performed. Heterogeneity was assessed using I2 statistics. RESULTS A total of 447 patients from seven randomized controlled trials were included in the meta-analysis. Results showed that the ingestion of curcumin decreased body mass index (WMD -0.267, 95% CI -0.450 to -0.084, P = 0.004, I2 = 0.0%), fasting plasma glucose (WMD -3.618, 95% CI -5.165 to -2.071, P < 0.001, I2 = 20.4%), insulin (WMD -1.834, 95% CI -2.701 to -0.968, P < 0.001, I2 = 8.4%), homeostatic model assessment for insulin resistance (WMD -0.565, 95% CI -0.779 to -0.351, P < 0.001, I2 = 0.0%), total cholesterol (WMD -15.591, 95% CI -27.908 to -3.273, P = 0.013, I2 = 68.9%), C-reactive protein (WMD -0.785, 95% CI -1.553 to -0.017, P = 0.045, I2 = 23.9%), and increased the quantitative insulin sensitivity check index (WMD 0.011, 95% CI 0.005 to 0.017, P = 0.001, I2 = 39.6%). As for safety, the treatment group did not cause significant adverse reactions than that in the control group. CONCLUSION In light of presented findings, curcumin has beneficial effects on serum markers of inflammation, weight loss and glucose and lipid metabolism in patients with PCOS. The incidence of adverse reactions does not increase with the application of curcumin. However, a larger, more definitive study is needed to further investigate these results.

Abstract
In recent years, epidemiological studies have suggested that metabolic disorders are nutritionally dependent. A healthy diet that is rich in polyphenols may be beneficial in the treatment of metabolic diseases such as polycystic ovary syndrome, metabolic syndrome, non-alcoholic fatty liver disease, cardiovascular disease, and, in particular, atherosclerosis. Curcumin is a polyphenol found in turmeric and has been reported to have antioxidant, anti-inflammatory, hepatoprotective, anti-atherosclerotic, and antidiabetic properties, among others. This review summarizes the influence of supplementation with curcumin on metabolic parameters in selected metabolic disorders.

Abstract
Cardiovascular diseases are the leading causes of the death around the world. An elevation of the low-density lipoprotein cholesterol (LDL-C) level is one of the most important risk factors for cardiovascular diseases. To achieve optimal plasma LDL-C levels, clinal therapies were investigated which targeted different metabolism pathways. However, some therapies also caused various adverse effects. Thus, there is a need for new treatment options and/or combination therapies to inhibit the LDL-C level. Dietary polyphenols have received much attention in the prevention of cardiovascular diseases due to their potential LDL-C lowering effects. However, the effectiveness and potential mechanisms of polyphenols in lowering LDL-C is not comprehensively summarized. This review focused on dietary polyphenols that could reduce LDL-C and their mechanisms of action. This review also discussed the limitations and suggestions regarding previous studies.

Abstract
Polycystic ovary syndrome (PCOS) is one of the most important gynecological disorders of women in the age of reproduction. Different hormonal and inflammatory cross-talks may play in the appearance of its eventual complications as a leading cause of infertility. Excessive production of reactive oxygen species over the power of the antioxidant system as oxidative stress is known to contribute to a variety of diseases like PCOS. Thus, the utilization of antioxidants can be efficient in preventing or assistant in treating these diseases. In this review, we describe the clinical trial studies that have examined the efficiency of antioxidant strategies against PCOS and the possible underlying mechanisms. The investigations presented here lead us to consider that targeting oxidative stress pathways is probably a powerful promising therapeutic approach towards PCOS. There is preparatory evidence of the effectiveness of antioxidant interventions in ameliorating some of the PCOS complications, including metabolic and hormonal disorders. Due to limited data and relatively few clinical trials, many of these interventions need further investigation before they can be considered effective agents for routine clinical use.

Abstract
Polycystic ovary syndrome (PCOS) is a heterogeneous condition that affects women of reproductive age. It is associated with menstrual disturbances, hyperandrogenism, and polycystic ovaries. In addition to this, it results in altered anthropometric parameters, insulin resistance, and subsequently untoward cardio-metabolic sequelae. Therapeutic approaches that target weight loss and improve insulin sensitivity are used to address the metabolic complications in PCOS. Curcumin is a phytochemical which exhibits anti-inflammatory and anti-oxidant properties, and therefore, its use in PCOS has been a subject of substantial interest and research. The aim of this study was to synthesize the existing evidence on the effects of curcumin on glycaemic and lipid parameters in PCOS. We searched PubMed, Embase, Web of Science, Scopus, and ClinicalTrials databases from inception to June 07, 2021. Only randomized controlled trials (RCT) presenting sufficient data on glycemic and lipid parameters in patients with PCOS at baseline and the end of the follow-up period in each group were included. Meta-analysis of five RCTs showed a significant reduction on fasting glucose (WMD: - 3.68 mg/dL, 95% CI: - 5.11, - 2.25, p < 0.00001, I2 = 18%), insulin levels (WMD: - 1.72 µUI/mL, 95% CI: - 2.53, -0.92, p < 0001, I2 = 41%), and HOMA-IR index (WMD: - 0.94, 95% CI: - 1.73, - 0.16, p = 0.02, I2 = 90%) after curcumin therapy. None of the lipid indices were significantly altered by curcumin. Curcumin administration in PCOS resulted in significant improvement in glycaemic parameters; however, no significant changes were seen in lipid parameters with its use.

Abstract
This review aims to evaluate if there are clinical benefits of curcumin (CUR) in patients with polycystic ovary syndrome (PCOS). Electronic databases (PubMed, EMBASE, Scopus, Web of Science, Cochrane Central, and Google Scholar) were systematically searched to identify only randomized clinical trials (RCTs) that assessed CUR in patients with PCOS from inception to May 5, 2021. Five RCTs were included with a total of 296 patients, with 148 among the CUR groups and 148 patients among the control group. Revised Cochrane risk-of-bias tool for randomized trials was used to assess the risk of bias, three RCTs provided a low risk of bias and two provided a high risk of bias. Compared with the control group, CUR was associated with a statistically significant improvement in the glycemic control including fasting blood glucose (MD = -3.67; 95% CI = [-5.25, -2.08], p < .00001), insulin level (MD = -1.91; 95% CI = [-2.97, -0.84], p = .0005), homeostasis model assessment of insulin resistance (MD = -0.55; 95% CI = [-0.83, -0.27], p = .0001), and quantitative insulin sensitivity check index (MD = 0.01; 95% CI = [0.00, 0.02], p = .0005). The mean difference in total cholesterol was also statistically significant (MD = -15.55; 95% CI = [-30.33, -0.76], p < .04). The rest of the secondary outcomes, including LDL, HDL, sex hormone, body weight, and CRP, were not statistically significant. This review concluded that among patients with PCOS, the use of CUR demonstrated a significant difference from the control group for glycemic control. Those findings suggest that CUR confers clinical benefits in patients with PCOS. However, due to the limited number of the included studies, further high-quality studies are needed to establish the clinical efficacy of the CUR.

Potential Health Benefits of Curcumin on Female Reproductive Disorders: A Review. Nutrients 2021; 13:nu13093126. [PMID: 34579002 PMCID: PMC8471428 DOI: 10.3390/nu13093126] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2021] [Revised: 09/03/2021] [Accepted: 09/04/2021] [Indexed: 12/11/2022] Open
Abstract
Curcumin is one of the main polyphenolic compounds in the turmeric rhizome. It possesses antioxidant, anti-inflammatory, anti-cancer, anti-arthritis, anti-asthmatic, anti-microbial, anti-viral and anti-fungal properties. This review aims to provide an overview of the potential health benefits of curcumin to treat female reproductive disorders, including polycystic ovary syndrome (PCOS), ovarian failure and endometriosis. Comprehensive information on curcumin was retrieved from electronic databases, which were MEDLINE via EBSCOhost, Scopus and Google Scholar. The available evidence showed that curcumin reduced the high level of androgen in PCOS. Studies in rodents suggest that curcumin resulted in the disappearance of cysts and the appearance of healthy follicles and corpora lutea. Furthermore, animal studies showed curcumin improved the overall function of the ovary in ovarian diseases and reversed the disturbance in oxidative stress parameters. Meanwhile, in vitro and in vivo studies reported the positive effects of curcumin in alleviating endometriosis through anti-inflammatory, anti-proliferative, anti-angiogenic and pro-apoptotic mechanisms. Thus, curcumin possesses various effects on PCOS, ovarian diseases and endometriosis. Some studies found considerable therapeutic effects, whereas others found no effect. However, none of the investigations found curcumin to be harmful. Curcumin clinical trials in endometriosis and ovarian illness are still scarce; thus, future studies need to be conducted to confirm the safety and efficacy of curcumin before it could be offered as a complementary therapy agent.

Abstract
Cardiovascular disease (CVD) is a major cause of death worldwide. Lipid abnormalities are one of the major risk factors for CVD. Curcumin is a natural polyphenol with lipid-lowering properties. Therefore, we carried out a systematic review to summarize the randomized controlled trials (RCTs) investigating the effect of curcumin on lipid profile in patients at risk of CVD. A comprehensive systematic search was conducted in PubMed, Scopus, Web of Science, and Google Scholar up to March 1, 2020, to identify controlled clinical trials assessing the effects of curcumin on lipid profile in patients at risk of CVD. From 1051 initially identified studies, 22 met the eligibility criteria. Curcumin supplementation significantly reduced at least one of the lipid profile indices (triglycerides, total cholesterol, low-density lipoprotein-cholesterol, and high-density lipoprotein-cholesterol) in 15 studies and improved more than one index in five studies. However, curcumin had no effect on any of lipid profile indices in seven studies. Overall, studies using a bioavailable formulation of curcumin had a better impact on the lipid profile. The findings of this systematic review showed that curcumin supplementation significantly reduced at least one of the lipid profile indices in more than two-thirds of the included studies. Curcumin might be used as an accessible, inexpensive, and safe agent to reduce risk of CVD. More randomized, clinical controlled trials are needed to verify these results.

The Effect of Curcumin Supplemsentation on Anthropometric Indices in Overweight and Obese Individuals: A Systematic Review of Randomized Controlled Trials. ADVANCES IN EXPERIMENTAL MEDICINE AND BIOLOGY 2021; 1291:121-137.

Abstract
BACKGROUND Curcumin is an active molecule present in turmeric and is the main therapeutic compound. There is growing evidence that curcumin could affect various anthropometric indices. We performed a systematic review to evaluate the efficacy of curcumin supplementation on anthropometric indices in obese and overweight individuals. METHODS A comprehensive search was conducted in PubMed, Scopus, Web of Science, and Google Scholar from inception up to February 2020 to identify randomized controlled trials investigating the effect of curcumin supplementation on anthropometric indices including body weight, body mass index (BMI), waist circumference (WC), hip circumference (HC), arm circumference (AC), waist-hip ratio (WHR), total body fat (TBF), and visceral fat (VF) in obese and overweight individuals. The Jadad scale was used to assess the quality of the included studies. RESULT Twenty-eight randomized controlled trials, comprising 2168 participants, were included in the systematic review. The results of 16 papers indicated that curcumin reduced at least one of the anthropometric indices among individuals with a BMI ≥ 25 kg/m2. Nevertheless, 12 articles showed that curcumin supplementation was not effective in any of the measured anthropometric factors. The included trials exhibited substantial heterogeneity in terms of the treatment protocol, follow-up duration, curcumin dosage, and background diseases of the participants. CONCLUSION Clinical trials that have independently examined the effects of curcumin in obese or overweight individuals are limited. However, available studies indicate that curcumin has beneficial impacts on various anthropometric indices. Further trials with longer duration of interventions are needed to confirm these findings.

Abstract
Polycystic ovarian syndrome (PCOS) is a combination of various symptoms like anovulation, hirsutism, chronic amenorrhea, infertility, obesity and polycystic ovaries. It affects over 7 million women worldwide. The current strategy to treat this disorder is based on the use of drugs that provide symptomatic relief. Most of these, however, exhibit numerous side effects and are not able to ameliorate all the signs and symptoms of PCOS. As dysbiosis is considered as one of the prime underlying causes of PCOS, restoration of eubiosis was considered as a plausible way to treat it. Bacteriotherpeutics like probiotics, synbiotics and even fecal microbiota transplant (FMT) have shown considerable effectiveness in PCOS. Of these baceteriotherapeutic options, FMT is considered to be the most holistic as it encompasses the bacteriome, virome, fungome, archaeome and even parasitome while both probiotics as well as synbiotics mainly comprise bacteria. Repeated FMT, however, is not a pragmatic option because of its inconvenience, lack of standardization, involved risk and scepticism amongst patients and physicians. If the eubiosis ushered by FMT is sustained for a long time, the repeated administrations of FMT can be avoided and maintenance therapy with any agent that can maintain the eubiotic condition can be adopted. Role of curcumin on gut microbiota is widely known. It is largely attributed to the ability of certain microbes to consume polyphenols as substrates and its positive effect on bacterial consumption of nutrients such as sugars. Based on various mechanisms and studies, a new hypothesis is being proposed wherein FMT and curcumin combination is predicted to be an effective and sustained treatment of PCOS with much lower rates of remission.

Abstract
BACKGROUND Polycystic ovarian syndrome (PCOS) is characterised by both metabolic and reproductive disorders, and affects 5% to 15% of women of reproductive age. Different western medicines have been proposed for PCOS-related subfertility, such as oral contraceptives, insulin sensitisers and laparoscopic ovarian drilling (LOD). Chinese herbal medicines (CHM) have also been used for subfertility caused by PCOS for decades, and are expected to become an alternative treatment for subfertile women with PCOS. OBJECTIVES To assess the efficacy and safety of Chinese herbal medicine (CHM) for subfertile women with polycystic ovarian syndrome (PCOS). SEARCH METHODS We searched the Cochrane Gynaecology and Fertility Group Specialised Register, CENTRAL, MEDLINE, Embase and six other databases, from inception to 2 June 2020. In addition, we searched three trials registries, the reference lists of included trials and contacted experts in the field to locate trials. SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing CHM versus placebo, no treatment or conventional (western) therapies for the treatment of subfertile women with PCOS. DATA COLLECTION AND ANALYSIS Two review authors independently screened trials for inclusion, assessed the risk of bias in included studies and extracted data. We contacted primary study authors for additional information. We conducted meta-analyses. We used the odds ratios (ORs) to report dichotomous data, with 95% confidence intervals (CIs). We assessed the certainty of the evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methods. MAIN RESULTS We included eight RCTs with 609 participants. The comparisons in the included trials were as follows: CHM versus clomiphene, CHM plus clomiphene versus clomiphene (with or without ethinyloestradiol cyproterone acetate (EE/CPA)), CHM plus follicle aspiration plus ovulation induction versus follicle aspiration plus ovulation induction alone, and CHM plus laparoscopic ovarian drilling (LOD) versus LOD alone. The overall certainty of the evidence for most comparisons was very low. None of the included studies reported the primary outcome, live birth rate. Most studies reported the secondary outcomes, and only one study reported data on adverse events. In trials that compared CHM to clomiphene (with or without LOD in both study arms), we are uncertain of the effect of CHM on pregnancy rates (odds ratio (OR) 1.41, 95% confidence interval (CI) 0.63 to 3.19; I2 = 28%; 3 studies, 140 participants; very low certainty evidence). Results suggest that if the chance of pregnancy following clomiphene is assumed to be 21.5%, the chance following CHM would vary between 14.7% and 46.7%. No study reported data on adverse events. When CHM plus clomiphene was compared to clomiphene (with or without EE/CPA), there was low certainty evidence of a higher pregnancy rate in the CHM plus clomiphene group (OR 3.06, 95% CI 2.05 to 4.55; I2 = 10%; 6 studies, 470 participants; low certainty evidence). Results suggest that if the chance of pregnancy following clomiphene is assumed to be 31.5%, the chance following CHM plus clomiphene would vary between 48.5% and 67.7%. No data were reported on adverse events. In trials that compared CHM plus follicle aspiration and ovulation induction to follicle aspiration and ovulation induction alone, we are uncertain of the effect of CHM on pregnancy rates (OR 1.62, 95% CI 0.46 to 5.68; 1 study, 44 women; very low certainty evidence). Results suggest that if the chance of pregnancy following follicle aspiration and ovulation induction is assumed to be 29.2%, the chance following CHM with follicle aspiration and ovulation induction would vary between 15.9% and 70%. Reported adverse events included severe luteinised unruptured follicle syndrome (LUFS) (Peto OR 0.60, 95% CI 0.06 to 6.14; 1 study, 44 women; very low certainty evidence), ovarian hyperstimulation syndrome (OHSS) (Peto OR 0.16, 95% CI 0.00 to 8.19; 1 study, 44 women; very low certainty evidence) or multiple pregnancy (Peto OR 0.60, 95% CI 0.06 to 6.14; 1 study, 44 women; very low certainty evidence). These results suggest that if the chances of LUFS, OHSS, and multiple pregnancy following follicle aspiration and ovulation induction are assumed to be 8.3%, 4.2%, and 8.3% respectively, the chances following CHM with follicle aspiration and ovulation induction would be 0.5% to 35.8%, 0% to 26.3% and 0.5% to 35.8% respectively. In trials that compared CHM plus LOD to LOD alone, we are uncertain if CHM improves pregnancy rates (OR 3.50, 95% CI 0.72 to 17.09; 1 study, 30 women; very low certainty evidence). Results suggest that if the chance of pregnancy following LOD is assumed to be 40%, the chance following CHM with LOD would vary between 32.4% and 91.9%. No data were reported on adverse events. We are uncertain of the results in the comparison groups for all outcomes. The certainty of the evidence for all other comparisons and outcomes was very low. The main limitations in the evidence were failure to report live birth or adverse events, failure to describe study methods in adequate detail and imprecision due to very low event rates and wide CIs. AUTHORS' CONCLUSIONS There is insufficient evidence to support the use of CHM for subfertile women with PCOS. No data are available on live birth. We are uncertain of the effect of CHM on pregnancy rates for there is no consistent evidence to indicate that CHM influences fertility outcomes. However, we find that the addition of CHM to clomiphene may improve pregnancy rates, but there is very limited, low certainty evidence for this outcome. Furthermore, there is insufficient evidence on adverse effects to indicate whether CHM is safe. In the future, well-designed, carefully conducted RCTs are needed, with a particular focus on the live birth rate and other safety indexes.

Abstract
Polycystic ovarian syndrome (PCOS) is the most common endocrine-metabolic disorder affecting a vast population worldwide; it is linked with anovulation, mitochondrial dysfunctions and hormonal disbalance. Mutations in mtDNA have been identified in PCOS patients and likely play an important role in PCOS aetiology and pathogenesis; however, their causative role in PCOS development requires further investigation. As a low-grade chronic inflammation disease, PCOS patients have permanently elevated levels of inflammatory markers (TNF-α, CRP, IL-6, IL-8, IL-18). In this review, we summarise recent data regarding the role of mtDNA mutations and mitochondrial malfunctions in PCOS pathogenesis. Furthermore, we discuss recent papers dedicated to the identification of novel biomarkers for early PCOS diagnosis. Finally, traditional and new mitochondria-targeted treatments are discussed. This review intends to emphasise the key role of oxidative stress and chronic inflammation in PCOS pathogenesis; however, the exact molecular mechanism is mostly unknown and requires further investigation.

Abstract
Polycystic ovary syndrome (PCOS) is a touchy clinical and public health problem worldwide, which adversely affects women's health and health-related comorbidities for lifetime, and represents a tremendous burden for both the family of the patient and for society. According to the diagnostic criteria used and the population studied, the prevalence rate of PCOS is between 6% and 21%. However, current conventional modern medicines for PCOS are only moderately effective at controlling the signs and symptoms, while they are not thoroughly able to prevent complications. Therefore, many patients have turned to complementary and alternative medical (CAM) treatments. CAM use is wide spread among patients with PCOS, and more than 70% of patients use CAM at one point during their diseases. The patients' primary motivations include dissatisfaction with available medications, perceive higher risk of drug side effects and crushing health burden and economic costs, desire for symptom relief, pursuit of shortening the course of disease, and the belief that CAM therapy is in accordance with the patients' values and beliefs. At present, several CAM methods have been used in women with PCOS, which has achieved obvious effects. However, biologically plausible mechanisms of the action of traditional Chinese medicine- (TCM-) associated CAM for PCOS have not been systematically reviewed. This review briefly summarizes the current progress of the impact of herbal medicine on the outcomes of PCOS and introduces the mechanisms.

Effects of Curcumin on Glycemic Control and Lipid Profile in Polycystic Ovary Syndrome: Systematic Review with Meta-Analysis and Trial Sequential Analysis. Nutrients 2021; 13:684. [PMID: 33669954 PMCID: PMC7924860 DOI: 10.3390/nu13020684] [Citation(s) in RCA: 33] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2021] [Revised: 02/09/2021] [Accepted: 02/18/2021] [Indexed: 12/11/2022] Open
Abstract
The therapeutic effects of curcumin for polycystic ovary syndrome (PCOS) remain inconclusive. The present study aims to evaluate the effects of curcumin on glycemic control and lipid profile in patients with PCOS. PubMed, Embase, Scopus, Web of Science, and Cochrane Library were searched from the inception through 28 November 2020. Randomized control trials (RCTs), which enrolled adult patients with PCOS, compared curcumin with placebo regarding the glycemic control and lipid profile, and reported sufficient information for performing meta-analysis, were included. Three RCTs were included. Curcumin significantly improves fasting glucose (mean difference (MD): -2.77, 95% confidence interval (CI): -4.16 to -1.38), fasting insulin (MD: -1.33, 95% CI: -2.18 to -0.49), Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) (MD: -0.32, 95% CI: -0.52 to -0.12), and quantitative insulin sensitivity check index (QUICKI) (MD: 0.010, 95% CI: 0.003-0.018). It also significantly improves high-density lipoprotein (MD: 1.92, 95% CI: 0.33-3.51) and total cholesterol (MD: -12.45, 95% CI: -22.05 to -2.85). In contrast, there is no statistically significant difference in the improvement in low-density lipoprotein (MD: -6.02, 95% CI: -26.66 to 14.62) and triglyceride (MD: 8.22, 95% CI: -26.10 to 42.53) between curcumin and placebo. The results of the fasting glucose, fasting insulin, HOMA-IR, QUICKI, and total cholesterol are conclusive as indicated by the trial sequential analysis. Curcumin may improve glycemic control and lipid metabolism in patients with PCOS and metabolic abnormality without significant adverse effects. Further studies are advocated to investigate the potential effects of curcumin on hyperandrogenism.
