Therapeutic approach for metabolic disorders and infertility in women with PCOS.

Polycystic ovary syndrome (PCOS) is a complex endocrine disorder affecting 5-10% of women of reproductive age. It generally shows with oligo/amenorrhea, anovulatory cycles, clinical o biochemical hirsutism, polycystic ovaries and, in a significant percentage of cases, insulin resistance. PCOS is defined as a multifactorial pathology, determined by the association of many factors: genetic, endocrine and environmental. The first and most effective treatment of PCOS is to change life-style and lose weight. The use of oral contraceptives has been shown effective in reducing acne and hirsutism and regulates the menstrual cycle. For women with severe hirsutism, the addition of antiandrogens to estrogen-progestin therapy has significantly improved the results. In cases of anovulatory infertility, the drug of first choice is clomiphene citrate, followed by low-dose gonadotropins. Recently, insulin-sensitizing drugs have been widely prescribed for PCOS patients. They are particularly effective in reducing insulin resistance and improving ovulatory performance. Besides insulin-sensitizing drugs, natural substances, such as inositol, seems to have good efficacy, similar to metformin with fewer side effects. New substances that could be used include statins and natural statins, such as monakolin, alone or combined with myo-inositol. These substances do not have side effects and greatly reduce the hyperandrogenic component in these patients.

Golimumab improves health-related quality of life of patients with moderate-to-severe ulcerative colitis: Results of the go-care study.

BACKGROUND: In recent years, improvement of Health-Related Quality of Life (HRQoL) in Ulcerative colitis (UC) has become a relevant measure for treatment efficacy. METHODS: We report results from a multicenter prospective study in Italy investigating HRQoL in adult patients with UC treated with golimumab (GLM). Patients who had shown clinical response after a 6-week induction phase (w0), were followed for an additional 48 weeks (w48) (total 54-week treatment). RESULTS: Of the 159 patients enrolled 90 completed the study. Compared to values at the beginning of treatment (n = 137), significant improvements were observed for mean total Inflammatory Bowel Disease Questionnaire (IBDQ) scores at w0 (168.5) and w48 (181.7). Patients with baseline PMS above the median tended to have greater improvements in IBDQ at w0 (OR 2.037, p = 0.033) and w48 (OR 3.292, p = 0.027). Compared to beginning of GLM treatment, the mean Full Mayo Score (FMS) decreased by 5.9 points at w48, while mean Partial Mayo Score (PMS) decreased by 3.9 points at w0 and by 4.9 points at w48. CONCLUSIONS: GLM improved HRQoL, disease activity and inflammatory biomarkers in UC patients with moderate-to-severely active disease. The greater the burden of disease activity at baseline, the greater the improvement of HRQoL after 24 and 48 weeks of treatment.

A 1-year follow-up study on checkpoint inhibitor-induced colitis: results from a European consortium.

BACKGROUND: Data regarding the clinical outcome of patients with immune checkpoint inhibitor (ICI)-induced colitis are scant. We aimed to describe the 12-month clinical outcome of patients with ICI-induced colitis. MATERIALS AND METHODS: This was a retrospective, European, multicentre study. Endoscopy/histology-proven ICI-induced colitis patients were enrolled. The 12-month clinical remission rate, defined as a Common Terminology Criteria for Adverse Events diarrhoea grade of 0-1, and the correlates of 12-month remission were assessed. RESULTS: Ninety-six patients [male:female ratio 1.5:1; median age 65 years, interquartile range (IQR) 55.5-71.5 years] were included. Lung cancer (41, 42.7%) and melanoma (30, 31.2%) were the most common cancers. ICI-related gastrointestinal symptoms occurred at a median time of 4 months (IQR 2-7 months). An inflammatory bowel disease (IBD)-like pattern was present in 74 patients (77.1%) [35 (47.3%) ulcerative colitis (UC)-like, 11 (14.9%) Crohn's disease (CD)-like, 28 (37.8%) IBD-like unclassified], while microscopic colitis was present in 19 patients (19.8%). As a first line, systemic steroids were the most prescribed drugs (65, 67.7%). The 12-month clinical remission rate was 47.7 per 100 person-years [95% confidence interval (CI) 33.5-67.8). ICI was discontinued due to colitis in 66 patients (79.5%). A CD-like pattern was associated with remission failure (hazard ratio 3.84, 95% CI 1.16-12.69). Having histopathological signs of microscopic colitis (P = 0.049) and microscopic versus UC-/CD-like colitis (P = 0.014) were associated with a better outcome. Discontinuing the ICI was not related to the 12-month remission (P = 0.483). Four patients (3.1%) died from ICI-induced colitis. CONCLUSIONS: Patients with IBD-like colitis may need an early and more aggressive treatment. Future studies should focus on how to improve long-term clinical outcomes.

[Evaluation of a new association between insulin-sensitizers and α-lipoic acid in obese women affected by PCOS]. / Valutazione di una nuova associazione tra insulino-sensibilizzanti e acido α-lipoico in donne obese affette da PCOS.

AIM: Polycystic ovary syndrome (PCOS) is a multifactorial pathology affecting 7-10% of the female population. Usually occurs with oligo/amenorrhea, anovulation, hirsutism, polycystic ovaries. Hyperinsulinemia associated with insulin resistance has been causally linked to all features of the syndrome. It has been demonstrated that by reducing hyperinsulinemia, in particular with the administration of metformin, insulin-lowering agents might improve endocrine and reproductive abnormalities in PCOS patients. METHODS: Original association between myo-inositol and alpha-lipoic acid, has recently been successfully administered in women with PCOS. The α-lipoic acid is a powerful natural antioxidant and an enzyme cofactor of the mitochondrial respiratory chain, is found to be a substance capable of improving glycemic control in patients with type II diabetes. In our study we compared two groups: group A, treated with metformin (3 g) and group B treated with metformin (1.7 g), myo-inositol and alpha-lipoic acid. RESULTS: The results of this study demonstrated a good efficacy of both treatments, although in the group treated with the combination of metformin/myo-inositol/alpha-lipoic acid improvement in hyperandrogenism, BMI and HOMA index were significantly better. CONCLUSION: Thus, the association metformin/myo-inositol/alpha-lipoic acid represents an excellent therapy choice to suggest to those obese women affected by PCOS who do not want to take hormones and neither to have any severe side effect.

[Evaluation of the myo-inositol-monacolin K association on hyperandrogenism and on the lipidic metabolism parameters in PCOS women]. / Valutazione dell'associazione myo-inositolo-monacolina K sull'iperandrogenismo e sui parametri del metabolismo lipidico in donne con PCOS.

AIM: Polycystic ovary syndrome (PCOS) is a multifactorial pathology affecting 5-10% of the female population. Usually occurs with oligo/amenorrhea, anovulation, hirsutism, polycystic ovaries. Hyperinsulinemia associated with insulin resistance has been causally linked to all features of the syndrome. It has been demonstrated that by reducing hyperinsulinemia, in particular with the administration of metformin, insulin-lowering agents might improve endocrine and reproductive abnormalities in PCOS patients. METHODS: A new molecule with insulin-sensitizing properties, myo-inositol, has recently been successfully administered in women with PCOS. New associations between natural substances like myo-inositol and other components have been proposed to improve the therapeutical efficacy. Among these substances, the monacolin K, a natural statin appeared to have important actions in cholesterol synthesis. In this article we study the effect of inositol alone and the association between myo-inositol and monacolinin K in the treatment of PCOS with insulin resistance, menstrual irregularities and hirsutism. RESULTS AND CONCLUSION: The results of this study demonstrated a good efficacy of both treatments, although in the group treated with the combination of myo-inositol/monacolin K improvement in lipids and hyperandrogenism were significantly better.

Elevated ectodomain of type 23 collagen is a novel biomarker of the intestinal epithelium to monitor disease activity in ulcerative colitis and Crohn's disease.

BACKGROUND: Impaired intestinal epithelial barrier is highly affected in inflammatory bowel disease. Transmembrane collagens connecting the epithelial cells to the extracellular matrix have an important role in epithelial cell homeostasis. Thus, we sought to determine whether the transmembrane type 23 collagen could serve as a surrogate marker for disease activity in patients with Crohn's disease and ulcerative colitis. METHODS: We developed an enzyme-linked immunosorbent assay to detect the ectodomain of type 23 collagen (PRO-C23) in serum, followed by evaluation of its levels in both acute and chronic dextran sulphate sodium colitis models in rats and human inflammatory bowel disease cohorts. Serum from 44 Crohn's disease and 29 ulcerative colitis patients with active and inactive disease was included. RESULTS: In the acute and chronic dextran sulphate sodium-induced rat colitis model, the PRO-C23 serum levels were significantly increased after colitis and returned to normal levels after disease remission. Serum levels of PRO-C23 were elevated in Crohn's disease (p < 0.05) and ulcerative colitis (p < 0.001) patients with active disease compared to healthy donors. PRO-C23 differentiated healthy donors from ulcerative colitis (area under the curve [AUC]: 0.81, p = 0.0009) and Crohn's disease (AUC: 0.70, p = 0.0124). PRO-C23 differentiated ulcerative colitis patients with active disease from those in remission (AUC: 0.75, p = 0.0219) and Crohn's disease patients with active disease from those in remission (AUC: 0.68, p = 0.05). CONCLUSION: PRO-C23 was elevated in rats with active colitis, and inflammatory bowel disease patients with active disease. Therefore, PRO-C23 may be used as a surrogate marker for monitoring disease activity in ulcerative colitis and Crohn's disease.

Down-regulation of p38 mitogen-activated protein kinase activation and proinflammatory cytokine production by mitogen-activated protein kinase inhibitors in inflammatory bowel disease.

Crohn's disease and ulcerative colitis are inflammatory bowel diseases (IBD) characterized by chronic relapsing mucosal inflammation. Tumour necrosis factor (TNF)-α, a known agonist of the mitogen-activated protein kinase (MAPK) pathway, is a key cytokine in this process. We aimed first to determine whether p38 MAPK is activated in IBD inflamed mucosa, and then studied the effect of four different p38α inhibitory compounds on MAPK phosphorylation and secretion of proinflammatory cytokines by IBD lamina propria mononuclear cells (LPMCs) and organ culture biopsies. In vivo phospho-p38α and p38α expression was evaluated by immunoblotting on intestinal biopsies from inflamed areas of patients affected by Crohn's disease and ulcerative colitis, and from normal mucosa of sex- and age-matched control subjects. Both mucosal biopsies and isolated LPMCs were incubated with four different p38α selective inhibitory drugs. TNF-α, interleukin (IL)-1ß and IL-6 were measured in the organ and cell culture supernatants by enzyme-linked immunosorbent assay. We found higher levels of phospho-p38α in the inflamed mucosa of IBD patients in comparison to controls. All the p38α inhibitory drugs inhibited p38α phosphorylation and secretion of TNF-α, IL-1ß and IL-6 from IBD LPMCs and biopsies. Activated p38α MAPK is up-regulated in the inflamed mucosa of patients with IBD. Additionally, all the p38α selective inhibitory drugs significantly down-regulated the activation of the MAPK pathway and the secretion of proinflammatory cytokines.

[Treatment with carnitine, acetyl carnitine, L-arginine and ginseng improves sperm motility and sexual health in men with asthenopermia]. / Il trattamento con carnitina, acetilcarnitina, L-arginina e ginseng migliora la motilità spermatica e la salute sessuale negli uomini con astenozoospermia.

AIM: Among the factors contributing to male infertility, asthenospermia constitutes both a health and a social problem frequently associated with alterations in sexual function. Studies have shown that acetyl carnitine and L-arginine improve sperm motility and that ginseng enhances libido and sexual performance. This study examined the effect of treatment with carnitine, acetyl carnitine, L-arginine and ginseng in men with idiopathic asthenospermia and altered sexual function. METHODS: The study population was 180 patients with asthenospermia randomly assigned to two groups: group A (90 men) received treatment and group B (90 men) did not. The sperm count was 16.6 ± 3.2 x 106/mL and the total sperm motility was 26.5 ± 3.4%. RESULTS AND CONCLUSION: Sexual satisfaction was measured using the sexual satisfaction index (SSI). At the end of therapy, a significant improvement was observed in progressive sperm motility on spermiogram evaluation and in SSI scores in the treatment group.

Differential regulation of interleukin 17 and interferon gamma production in inflammatory bowel disease.

BACKGROUND AND AIMS: Interleukin 17 (IL17) is now known to be involved in a number of chronic inflammatory disorders. However, the mechanisms regulating its production in inflammatory bowel disease (IBD) are still unclear. METHODS: Endoscopic biopsies or surgical specimens were taken from inflamed and uninflamed colonic mucosa of 72 patients with IBD (38 with Crohn's disease and 34 with ulcerative colitis), and normal colon of 38 control subjects. IL17 and interferon gamma (IFNgamma) were detected by ELISA in the supernatants of biopsies cultured ex vivo, and anti-CD3/CD28-stimulated lamina propria mononuclear cells (LPMCs) incubated with IL12, IL23, IL1beta plus IL6, transforming growth factor beta1 (TGFbeta1), or anti-IL21 neutralising antibody. Intracellular flow cytometry was performed to analyse mucosal Th17 and Th1/Th17 cells. RESULTS: IL17 production by organ culture biopsies was higher in IBD inflamed mucosa than IBD uninflamed mucosa and controls, and was equivalent in amount to IFNgamma. Anti-CD3/CD28-stimulated IBD LPMCs produced higher IL17 amounts compared to controls. The percentages of Th17 and Th1/Th17 cells were increased in patients with IBD. IL23 and IL1beta plus IL6 had no effect on IBD LPMC production of IL17; however, IL12 markedly increased IFNgamma production and decreased IL17 production. TGFbeta1 dose-dependently decreased IFNgamma, but had no significant inhibitory effect on IL17 production. Blocking IL21 significantly downregulated IL17 production. CONCLUSIONS: Our findings support a role for IL12, TGFbeta and IL21 in modulating IL17/IFNgamma production in IBD. The abundant IL17 in inflamed IBD mucosa may help explain the relative lack of efficacy of anti-IFNgamma antibodies in clinical trials of Crohn's disease.

Transforming growth factor beta signalling and matrix metalloproteinases in the mucosa overlying Crohn's disease strictures.

BACKGROUND AND AIMS: In addition to its crucial role in dampening tissue-damaging immune responses in the gut, transforming growth factor beta (TGFbeta) is a potent profibrogenic agent inducing collagen synthesis and regulating the balance between matrix-degrading matrix metalloproteinases (MMPs) and their inhibitors (TIMPs). TGFbeta signalling was investigated by analysis of Smad proteins and MMPs/TIMPs in the mucosa overlying strictures in patients with Crohn's disease (CD). METHODS: Specimens were collected from macroscopically normal mucosa overlying strictured and non-strictured gut of patients with fibrostenosing CD. Isolated myofibroblasts were cultured with anti-TGFbeta blocking antibody or TGF beta 1. TGFbeta transcripts were analysed by quantitative reverse transcription-PCR (RT-PCR). Smad proteins and MMPs were determined by immunoblotting. MMP-12 activity was measured by a real-time MMP-12 activity assay. An in vitro wound-healing scratch assay was used to assess myofibroblast migration. RESULTS: TGFbeta transcripts, phosphorylated Smad2-Smad3 (pSmad2-3) and TIMP-1 proteins were higher in mucosa overlying strictures than in mucosa overlying non-strictured areas. In contrast, mucosa overlying strictured gut had lower expression of Smad7, MMP-12 and MMP-3. Myofibroblasts from mucosa overlying strictured gut showed higher TGFbeta transcripts, a greater pSmad2-3 response to TGFbeta, increased TIMP-1, lower Smad7, increased collagen production and reduced migration ability compared with myofibroblasts from mucosa overlying non-strictured gut. TGFbeta blockade increased myofibroblast MMP-12 production and migration, more obviously in myofibroblasts isolated from mucosa overlying non-strictured compared with strictured gut. CONCLUSIONS: Changes in TGF-beta signalling and MMP production were identified in the mucosa overlying strictures in CD which may give a window into the process of fibrosis.

mTOR sustains inflammatory response in celiac disease.

Celiac disease (CD) is an enteropathy triggered by the ingestion of gluten proteins in genetically predisposed individuals and characterized by excessive activation of effector immune cells and enhanced production of inflammatory cytokines. However, factors/mechanisms that amplify the ongoing mucosal inflammation in CD are not fully understood. In this study, we assessed whether mammalian target of Rapamycin (mTOR), a pathway that combines intra- and extra-cellular signals and acts as a central regulator for the metabolism, growth, and function of immune and non-immune cells, sustains CD-associated immune response. Our findings indicate that expression of phosphorylated (p)/active form of mTOR is increased in protein lysates of duodenal biopsy samples taken from patients with active CD (ACD) as compared to normal controls. In ACD, activation of mTOR occurs mainly in the epithelial compartment and associates with enhanced expression of p-4EBP, a downstream target of mTOR complex (mTORC)1, while expression of p-Rictor, a component of mTORC2, is not increased. Stimulation of mucosal explants of inactive CD patients with pepsin-trypsin-digested (PT)-gliadin or IFN-γ/IL-21, two cytokines produced in CD by gluten-specific T cells, increases p-4EBP expression. Consistently, blockade of such cytokines in cultures of ACD mucosal explants reduces p-4EBP. Finally, we show that inhibition of mTORC1 with rapamycin in ACD mucosal explants reduces p-4EBP and production of IL-15, a master cytokine produced by epithelial cells in this disorder. Our data suggest that ACD inflammation is marked by activation of mTORC1 in the epithelial compartment.

Blockade of transforming growth factor beta upregulates T-box transcription factor T-bet, and increases T helper cell type 1 cytokine and matrix metalloproteinase-3 production in the human gut mucosa.

BACKGROUND AND AIMS: The role of transforming growth factor beta (TGFbeta) in inhibiting T cell function in the normal gut has been studied in animal models. However, the impact of TGFbeta inhibition on T cells in the normal human gut remains poorly understood. The effect of TGFbeta blockade in normal intestinal biopsies grown ex vivo and lamina propria mononuclear cells (LPMCs) on T-bet, a T-box transcription factor required for T helper cell type (Th)1 differentiation, interferon gamma (IFN gamma) production, T cell apoptosis and matrix metalloproteinase (MMP)-3 production has therefore been tested. METHODS: TGFbeta transcripts were determined by quantitative reverse transcription-PCR in laser-captured gut epithelium and lamina propria. Biopsies and LPMCs were cultured with anti-TGFbeta neutralising antibody. After 24 h culture, T-bet was determined by immunoblotting, and T cell apoptosis was assessed by flow cytometry. IFN gamma, tumour necrosis factor alpha (TNFalpha), interleukin (IL) 2, IL6, IL8, IL10, IL12p70 and IL17 were measured by ELISA. MMP-3 and tissue inhibitor of matrix metalloproteinase (TIMP)-1 were assessed by immunoblotting. RESULTS: A higher number of TGFbeta transcripts was found in the lamina propria than in the epithelium in normal gut. T-bet expression was significantly higher in biopsies and LPMCs cultured with anti-TGFbeta antibody than in those cultured with control antibody. TGFbeta blockade downregulated T cell apoptosis, and induced a significant increase in IFN gamma, TNFalpha, IL2, IL6, IL8 and IL17 production. A higher expression of MMP-3, but not TIMP-1, was observed in the tissue and supernatant of biopsies treated with anti-TGFbeta antibody. CONCLUSIONS: The findings support a crucial role for TGFbeta in dampening T cell-mediated tissue-damaging responses in the human gut.

An expert consensus to standardise definitions, diagnosis and treatment targets for anti-fibrotic stricture therapies in Crohn's disease.

BACKGROUND: Fibrotic stricture is a common complication of Crohn's disease (CD) affecting approximately half of all patients. No specific anti-fibrotic therapies are available; however, several therapies are currently under evaluation. Drug development for the indication of stricturing CD is hampered by a lack of standardised definitions, diagnostic modalities, clinical trial eligibility criteria, endpoints and treatment targets in stricturing CD. AIM: To standardise definitions, diagnosis and treatment targets for anti-fibrotic stricture therapies in Chron's disease. METHODS: An interdisciplinary expert panel consisting of 15 gastroenterologists and radiologists was assembled. Using modified RAND/University of California Los Angeles appropriateness methodology, 109 candidate items derived from systematic review and expert opinion focusing on small intestinal strictures were anonymously rated as inappropriate, uncertain or appropriate. Survey results were discussed as a group before a second and third round of voting. RESULTS: Fibrotic strictures are defined by the combination of luminal narrowing, wall thickening and pre-stenotic dilation. Definitions of anastomotic (at site of prior intestinal resection with anastomosis) and naïve small bowel strictures were similar; however, there was uncertainty regarding wall thickness in anastomotic strictures. Magnetic resonance imaging is considered the optimal technique to define fibrotic strictures and assess response to therapy. Symptomatic strictures are defined by abdominal distension, cramping, dietary restrictions, nausea, vomiting, abdominal pain and post-prandial abdominal pain. Need for intervention (endoscopic balloon dilation or surgery) within 24-48 weeks is considered the appropriate endpoint in pharmacological trials. CONCLUSIONS: Consensus criteria for diagnosis and response to therapy in stricturing Crohn's disease should inform both clinical practice and trial design.

Role of macrophage metalloelastase in gut inflammation.

Matrix metalloproteinases (MMPs) are involved in a number of physiological and pathologic processes including the inflammation found in IBD. We have shown that MMP-3 is upregulated in Crohn's disease and in ulcerative colitis. This study shows a potential role for MMP-12 in these idiopathic diseases.

Impact of patient characteristics on the clinical efficacy of mongersen (GED-0301), an oral Smad7 antisense oligonucleotide, in active Crohn's disease.

BACKGROUND: In a phase 2 study, mongersen, an oral antisense oligonucleotide targeting Smad7, was effective in inducing clinical remission in approximately 60% of patients with active Crohn's disease (CD). AIM: In a post hoc analysis to evaluate those patient disease characteristics that may have influenced the efficacy and safety of mongersen therapy. METHODS: Patients with steroid-dependent/resistant, active CD were randomised to mongersen 10, 40 or 160 mg/day or placebo for 2 weeks; patients were followed for 10 weeks. Clinical remission [Crohn's Disease Activity Index (CDAI) score <150] and clinical response (CDAI score reduction ≥100 points) were assessed at weeks 2, 4 and 12 for these subgroups: disease duration <5/≥5 years, human serum C-reactive protein (hsCRP) <3/≥3 mg/L, and CDAI at baseline ≤260/>260. Additional patient baseline and disease characteristics were explored. RESULTS: Clinical remission and response rates were significantly higher in patients receiving mongersen 40 and 160 mg/day but not 10 mg/day vs. placebo and independent of disease duration and hsCRP. Patients with baseline CDAI ≤260 had significantly higher remission rates with 40 and 160 mg/day. In patients with baseline CDAI >260, remission rates were statistically greater with 160 mg/day and numerically better with 40 mg/day vs. placebo. Adverse event rates were similar across treatment groups. Mongersen was safe and well tolerated. CONCLUSIONS: Patients with higher CDAI scores achieved clinical remission most frequently with the highest mongersen dose. Disease duration and baseline human serum C-reactive protein did not appear to significantly impact efficacy of mongersen in this study (EudraCT Number: 2011-002640-27.).

Oral butyrate for mildly to moderately active Crohn's disease.

BACKGROUND: Butyrate exerts anti-inflammatory effects in experimental colitis and on Crohn's disease lamina propria mononuclear cells in vitro. AIM: To explore the efficacy and safety of oral butyrate in Crohn's disease. METHODS: Thirteen patients with mild-moderate ileocolonic Crohn's disease received 4 g/day butyrate as enteric-coated tablets for 8 weeks. Full colonoscopy and ileoscopy were performed before and after treatment. Endoscopical and histological score, laboratory data, Crohn's disease activity index and mucosal interleukin (IL)-1beta, IL-6, IL-12, interferon-gamma, tumour necrosis factor-alpha and nuclear factor-kappa B (NF-kappaB) were assessed before and after treatment. RESULTS: One patient withdrew from the study, and three patients did not experience clinical improvement. Among the nine patients (69%) who responded to treatment, seven (53%) achieved remission and two had a partial response. Endoscopical and histological score significantly improved after treatment at ileocaecal level (P < 0.05). Leucocyte blood count, erythrocyte sedimentation rate and mucosal levels of NF-kappaB and IL-1beta significantly decreased after treatment (P < 0.05). CONCLUSIONS: Oral butyrate is safe and well tolerated, and may be effective in inducing clinical improvement/remission in Crohn's disease. These data indicate the need for a large investigation to extend the present findings, and suggest that butyrate may exert its action through downregulation of NF-kappaB and IL-1beta.

Polycystic ovary syndrome (PCOS) and hyperandrogenism: the role of a new natural association.

AIM: Polycystic ovary syndrome (PCOS) affects 5-10% of women of childbearing age and manifests itself through oligomenorrhea, anovulation, hirsutism, micro-polycystic ovaries. Insulin resistance is a characteristic of PCOS patients and is more pronounced in obese patients. Insulin resistance and consequent hyperinsulinemia are related to many aspects of the syndrome such as hyperandrogenism, reproductive disorders, acne and hirsutism. In the long-term it may increase the risk of cardiovascular disease and negatively affect lipid profile and blood pressure. Changes in lifestyle and diet can partially improve these aspects. The use of insulin-sensitizing drugs such as metformin often normalises the menstrual cycle, improving hyperandrogenism and, subsequently, the response to ovulation induction therapies. New molecules have recently been marketed, that produce the same results, but without the side-effects. One of these is myo-inositol, a new insulin-sensitizing molecule which has been successfully administered to women suffering from PCOS. Associations between inositol and other compounds that can increase the therapeutic effect have been proposed. Of these, we found to be interesting the association with monacolin K, a natural statin that reduces cholesterol levels starting point of the synthesis of steroids, including androgens, and lipoic acid, known for its anti-inflammatory, antioxidant and insulin-sensitizing activity. We decided to assess the efficacy of the product. METHODS: We recruited 30 women aged between 24 and 32 years suffering from PCOS with insulin resistance, HOMA index>2.5 and no other endocrine diseases. The following were assessed: Body Mass Index (BMI), characteristics of menstrual cycles, lipid profile (total cholesterol, and HDL), androgens (total testosterone and androstenedione). The patients were also assessed for the degree of hirsutism using the Ferriman-Gallwey Score>8. The subjects were divided into two groups: Group A, treated with an association of 1 g myo-inositol, 5 mg monacolin K and 400 mg lipoic acid for 6 months; Group B, treated with a double dosage of 2 g myo-inositol, 10 mg monacolin K, 800 mg lipoic acid for 6 months. RESULTS: The results have shown good efficacy of both dosages, although women treated with a double dosage of myo-inositol, monacolin K and lipoic acid showed a significantly greater improvement in terms of lipid parameters and those connected with hyperandrogenism. CONCLUSION: This new myo-inositol, monacolin K and lipoic acid association contains appropriate substances to contrast various etiopathogenic elements responsible for the onset of PCOS and the symptoms of hyperandrogenism and dyslipidemia related to it.
