RESUMEN

PURPOSE: Functional hypothalamic amenorrhea (FHA) is characterized by an estrogen deficiency which in turn can cause vascular dysfunction. The aim of this study is to evaluate any changes in the chorio-retinal circulation in patients affected by FHA. 24 patients with FHA and 24 age-matched controls underwent a gynecological evaluation and an OCT angiography (OCTA) to study chorio-retinal vascularization. RESULTS: OCTA in FHA patients showed an increase in vessel density in the choriocapillaris (CC) layer (both in the fovea area, at 5% p value = 0.037 and in the whole area, at 5% p value = 0.028) and an increase in vascular density in the deep fovea (DVP) (at 10% p value = 0.096) in the whole district compared to controls. Simple linear regressions show a significant negative association between CC vessel density and insulin (p = 0.0002) and glucose values (p = 0.0335) for the fovea district and a negative association between DVP vessel density and endometrial thickness (at 10%, p value: 0.095) in the whole district. CONCLUSION: Our study shows that CC vessel density is increased in women affected by FHA. This could represent a compensation effort to supply the vascular dysfunction caused by estrogen deficiency. We also found an increasing trend in vascular density in DVP associated with the decrease of endometrial thickness, an indirect sign of estrogenization. Considering that these changes occur in absence of visual defects, they could be used as a biomarker to estimate hypoestrogenism-induced microcirculation changes before clinical appearance.

RESUMEN

Functional hypothalamic amenorrhea (FHA) is characterized by estrogen deficiency that significantly impacts metabolic, bone, cardiovascular, mental, and reproductive health. Given the importance of environmental factors such as stress and body composition, and particularly considering the importance of estrogens in regulating the gut microbiota, some changes in the intestinal microenvironment are expected when all of these factors occur simultaneously. We aimed to assess whether the gut microbiota composition is altered in FHA and to determine the potential impact of hormonal replacement therapy (HRT) on the gut microbiota. This prospective observational study included 33 patients aged 18-34 yr with FHA and 10 age-matched healthy control women. Clinical, hormonal, and metabolic evaluations were performed at baseline for the FHA group only, whereas gut microbiota profile was assessed by 16S rRNA gene amplicon sequencing for both groups. All measurements were repeated in patients with FHA after receiving HRT for 6 mo. Gut microbiota alpha diversity at baseline was significantly different between patients with FHA and healthy controls (P < 0.01). At the phylum level, the relative abundance of Fusobacteria was higher in patients with FHA after HRT (P < 0.01), as was that of Ruminococcus and Eubacterium at the genus level (P < 0.05), which correlated with a decrease in circulating proinflammatory cytokines. FHA is a multidimensional disorder that is interconnected with dysbiosis through various mechanisms, particularly involving the gut-brain axis. HRT appears to induce a favorable shift in the gut microbiota in patients with FHA, which is also associated with a reduction in the systemic inflammatory status.NEW & NOTEWORTHY Our study marks the first comprehensive analysis of gut microbiota composition in FHA and the impact of HRT on it, along with biochemical, anthropometric, and psychometric aspects. Our results indicate distinct gut microbiota composition in patients with FHA compared with healthy individuals. Importantly, HRT prompts a transition toward a more beneficial gut microbiota profile and reduced inflammation. This study validates the concept of FHA as a multifaceted disorder interlinked with dysbiosis, particularly involving the gut-brain axis.

RESUMEN

BACKGROUND: Polycystic ovary syndrome (PCOS) is a low-grade inflammatory disease characterized by anovulation and hyperandrogenism, associated with insulin-resistance. The aim of our study was to investigate the effects of a treatment with alpha-lipoic acid on clinical, endocrine, and metabolic features of women affected by PCOS. METHODS: In this pilot cohort study, 60 women (30 hyperinsulinemic and 30 normoinsulinemic patients; age 15-34 years) were enrolled and clinical, hormonal, and metabolic parameters were evaluated before and after a six-months treatment with alpha-lipoic acid 800 mg/daily. Investigations were performed during the early follicular phase of the menstrual cycles (spontaneous or progestin-induced cycles): after fasting overnight for 10-12 h, blood samples were collected for hormonal and metabolic assays and oral glucose tolerance test and pelvic ultrasound were performed. Total Antioxidant Capacity was expressed as LAG time. RESULTS: The treatment was able to increase the number of menstrual cycles during the 6 months considered in all patients and to reduce BMI in the normoinsulinemic population. In hyperinsulinemic patients we observed a statistically significant reduction in AUC-I as well as an increase of total antioxidant capacity. CONCLUSIONS: The relevant results in restoring menstrual cyclicity in both groups, in addition to the antioxidant effect, confirm that hyperinsulinemia influences only the metabolic response to the treatment, without predict the ovarian function. Even if alpha-lipoic acid mechanisms of action is not clear and further studies are needed to confirm these results, it could be considered a valid therapeutic alternative to traditional drugs, without side effects as reported.

RESUMEN

PURPOSE: Patients with functional hypothalamic amenorrhea (FHA) could commonly have bone damage, often preceded by metabolic alterations due to a relative energy deficit state. To date, there are no markers capable of predicting osteopenia before it is manifested on DXA. Irisin is a myokine that promotes the differentiation of osteoblastic cells and appears to be inversely correlated with the incidence of bone fragility and fractures in postmenopausal women. The aim of this study was to measure irisin levels in FHA patients and to correlate it with bone density parameters. METHODS: Thirty-two patients with FHA and 19 matched controls underwent the same clinical and laboratory evaluation. RESULTS: Irisin and body mass index (BMI) were significantly lower in the case group than in healthy controls (2.03 ± 0.12 vs. 2.42 ± 0.09 p < 0.05 and 19.43 ± 2.26 vs. 22.72 ± 0.67 p < 0.05, respectively). Additionally, total body mass density (BMD g/cm2) was significantly lower in the case group than in the healthy controls (1.09 ± 0.08 vs. 1.14 ± 0.05, p < 0.05), without signs of osteopenia. CONCLUSIONS: The FHA group showed lower irisin levels associated with significantly reduced BMD parameters that did not reach the severity of osteopenia. Therefore, we could speculate that irisin could predict DXA results in assessing modifications of body composition parameters. Future research is warranted to study these parameters in a larger population to confirm our results, so that irisin could be used as a predictor and screening method for bone deprivation. Furthermore, irisin is strictly related to energy metabolism and could be an indirect marker of nutritional status in FHA patients, identifying earlier states of energy deficit.

RESUMEN

The objective of the study was to investigate the effects of 6 months of melatonin administration on clinical, endocrine, and metabolic features of women affected by polycystic ovary syndrome (PCOS). This is a prospective cohort study including 40 normal-weight women with PCOS between January and September 2016, enrolled in an academic research environment. Ultrasonographic pelvic examinations, hirsutism score evaluation, hormonal profile assays, oral glucose tolerance test, and lipid profile at baseline and after 6 months of melatonin administration were performed. Melatonin treatment significantly decreased androgens levels (free androgen index: P < .05; testosterone: P < .01; 17 hydroxyprogesterone: P < .01). Follicle-stimulating hormone levels significantly raised ( P < .01), and anti-Mullerian hormone serum levels significantly dropped after 6 months of melatonin treatment ( P < .01). No significant changes occurred in glucoinsulinemic and lipid parameters after treatment except a significant decrease of low-density lipoprotein cholesterol. Almost 95% of participants experienced an amelioration of menstrual cycles. Until now, only few data have been published about the role of melatonin in women with PCOS. This is the first study focused on the effects of exogenous oral melatonin administration on the clinical, endocrine, and metabolic characteristics of patients with PCOS. After 6 months of treatment, melatonin seems to improve menstrual irregularities and biochemical hyperandrogenism in women with PCOS through a direct, insulin-independent effect on the ovary. Based on our results, melatonin could be considered a potential future therapeutic agent for women affected by PCOS.

RESUMEN

The aim of our study was to investigate the effects of a combined treatment with alpha-lipoic acid (ALA) and myoinositol (MYO) on clinical, endocrine and metabolic features of women affected by polycystic ovary syndrome (PCOS). In this pilot cohort study, forty women with PCOS were enrolled and clinical, hormonal and metabolic parameters were evaluated before and after a six-months combined treatment with ALA and MYO daily. Studied patients experienced a significant increase in the number of cycles in six months (p < 0.01). The free androgen index (FAI), the mean androstenedione and DHEAS levels significantly decreased after treatment (p < 0.05). Mean SHBG levels significantly raised (p < 0.01). A significant improvement in mean Ferriman-Gallwey (F-G) score (p < 0.01) and a significant reduction of BMI (p < 0.01) were also observed. A significant reduction of AMH levels, ovarian volume and total antral follicular count were observed in our studied women (p< 0.05). No significant changes occurred in gluco-insulinaemic and lipid parameters after treatment. The combined treatment of ALA and MYO is able to restore the menstrual pattern and to improve the hormonal milieu of PCOS women, even in the absence of apparent changes in insulin metabolism.

RESUMEN

OBJECTIVE: To evaluate anti-Müllerian hormone (AMH) concentrations and antral follicle counts (AFCs) in the prediction of pregnancy outcomes after controlled ovarian stimulation among women undergoing intrauterine insemination. METHODS: A retrospective study included women with unexplained infertility aged 41years or younger who attended a fertility clinic in Italy between December 2009 and May 2014. Ovarian stimulation was achieved with recombinant follicle-stimulating hormone or highly purified human menopausal gonadotropin. Receiver operating characteristic curves were generated to predict ongoing pregnancy. The primary outcome was the association between AMH/AFC and ongoing pregnancy, and was assessed by logistic regression. RESULTS: Overall, 276 women were included, of whom 43 (15.6%) achieved ongoing pregnancy. Multivariate analysis showed that women with a serum day-3 concentration of AMH higher than 2.3ng/mL were more likely to have ongoing pregnancy than were those with a concentration lower than 2.3ng/mL (odds ratio 5.84, 95% confidence interval 2.38-14.31; P<0.001). No associations were recorded for AFCs. CONCLUSION: AMH should be used to predict the pregnancy outcome of intrauterine insemination.

RESUMEN

OBJECTIVE: Women affected by PCOS and psoriasis are more likely to have insulin-resistance, hyperinsulinemia, reduced HDL cholesterol levels and a more severe degree of skin disease than those with psoriasis alone. The mechanism underlying this association between PCOS and psoriasis is currently unknown. The aim of the present study was to evaluate the features of psoriasis and the psoriasis severity scores in the different PCOS phenotypes and in age and body mass index (BMI)-matched psoriatic control patients. STUDY DESIGN: A cross-sectional study was performed on 150 psoriatic patients: 94 PCOS and 56 age- and BMI-matched controls. PCOS patients were diagnosed and divided into four phenotypes according to Rotterdam criteria: A - patients with complete phenotype with hyperandrogenism (H) plus oligoamenorrhea (O) plus polycystic ovary (PCO) on ultrasound examination; B - patients with H plus O (without PCO); C - patients with H plus PCO (ovulatory phenotype); D - patients with O plus PCO (without H). The patient's Psoriasis Area and Severity Index (PASI) as well as the Physician's Global Assessment (PGA) were calculated. A PASI score ≥10 was correlated with common indicator of severe disease. A PGA ≥4 was considered as a condition of moderate to severe disease. RESULTS: Among the four phenotypes investigated, the group with complete phenotype (H plus O plus PCO) had a higher prevalence of patients with patient's PASI ≥10 compared to controls (Odds Ratio (OR) 4.71, 95% confidence intervals (CI) 1.59-13.95). The group with O plus PCO had a higher prevalence of patients with PGA ≥4 compared to controls (OR 26.79, 95% CI 3.40-211.02) while the ovulatory group had a lower prevalence of patients with PGA ≥4 (OR 0.06, 95% CI 0.01-0.51). CONCLUSIONS: The ovulatory phenotype displays a milder psoriasis form than other phenotypes while the phenotypes with oligoamenorrhea presented higher severity scores of disease than other phenotypes and control group.

RESUMEN

OBJECTIVE: Tubal patency in women with endometriosis has traditionally been evaluated by laparoscopy. The aim of this study was to investigate the accuracy of hysterosalpingo-contrast-sonography (HyCoSy) in the assessment of tubal patency in these women. STUDY DESIGN: A retrospective study was conducted at Physiopathology of Human Reproduction Unit. Infertile women who underwent HyCoSy and then a laparoscopy (dye test) within 6 months from the HyCoSy were included. Tubal patency was assessed by HyCoSy and the findings were compared with the results of laparoscopy, which was considered the gold standard for assessment of tubal patency. Sensitivity, specificity, positive and negative predictive values (PPV, NPV) and positive and negative likelihood ratios (Lh+, Lh-) were calculated including the 95% confidence interval (CI). RESULTS: A total of 1452 women underwent HyCoSy and 126 of them received a laparoscopy within 6 months from the HyCoSy. Of the 126 women, 42 (33.3%) had a diagnosis of pelvic endometriosis and 84 (66.7%) had no endometriosis. In the endometriosis population, HyCoSy showed a sensitivity, specificity, PPV, NPV, Lh+ and Lh- of 85% (95% CI 62-96), 93% (95% CI 82-97), 81% (95% CI 58-94), 94% (95% CI 84-98), 12.6 (95% CI 4.8-33) and 0.15 (95% CI 0.05-0.4) respectively. In the non-endometriosis group, HyCoSy showed a sensitivity, specificity, PPV, NPV, LR+ and LR- of 85% (95% CI 65-95), 93% (95% CI 87-96), 71% (95% CI 53-85), 97% (95% CI 92-99), 13.2 (95% CI 6.9-25) and 0.15 (95% CI 0.06-0.3) respectively. The diagnostic accuracy of HyCoSy was 91% in the endometriosis group and 92% in the non-endometriosis patients. CONCLUSIONS: HyCoSy showed high accuracy in evaluating tubal patency in infertile non-endometriosis women and in those affected by endometriosis.

RESUMEN

STUDY QUESTION: Is the treatment with recombinant FSH (rFSH) plus recombinant LH (rLH) more effective than highly purified (HP)-hMG in terms of ongoing pregnancy rate (PR) in women ≥35 years of age undergoing intrauterine insemination (IUI) cycles? SUMMARY ANSWER: The ongoing PR was not significantly different in women treated with rFSH plus rLH or with HP-hMG. WHAT IS KNOWN ALREADY: Although previous studies have shown beneficial effects of the addition of LH activity to FSH, in terms of PR in patients aged over 34 years having ovulation induction, no studies have compared two different gonadotrophin preparations containing LH activity in women ≥35 years of age in IUI cycles. STUDY DESIGN, SIZE, DURATION: A single-centre RCT was performed between May 2012 and September 2013 with 579 women ≥35 years of age undergoing IUI cycles. The patients were randomly assigned to one of the two groups, rFSH in combination with rLH group or HP-hMG (Meropur) group, by giving them a code number from a computer generated randomization list, in order of enrolment. The randomization visit took place on the first day of ovarian stimulation. PARTICIPANTS/MATERIALS, SETTING, METHODS: Five hundred and seventy-nine patients with unexplained infertility or mild male factor undergoing IUI cycles were recruited in a university hospital setting. All women were enrolled in this study only for one cycle of treatment. Five hundred and seventy-nine cycles were included in the final analysis. Two hundred and ninety patients were treated with rFSH in combination with rLH and 289 patients were treated with HP-hMG. The ovarian stimulation cycle started on the third day of the menstrual cycle and the starting gonadotrophin doses used were 150 IU/day of rFSH plus 150 IU/day of rLH or 150 IU/day of HP-hMG. The drug dose was adjusted according to the individual follicular response. A single IUI per cycle was performed 34-36 h after hCG injection. MAIN RESULTS AND THE ROLE OF CHANCE: The main outcome measures were ongoing PR and number of interrupted cycles for high risk of ovarian hyperstimulation syndrome (OHSS). Ongoing pregnancy rates were 48/290 (17.3%) in the recombinant group versus 35/289 (12.2%) in the HP-hMG group [(odds ratio (OR) 1.50, 95% CI 0.94-2.41, P = 0.09]. The number of interrupted cycles for high risk of OHSS was 13/290 (4.5%) in the rFSH plus rLH group and 2/289 (0.7%) in the HP-hMG group (OR 6.73, 95% CI 1.51-30.12, P = 0.013). LIMITATIONS, REASONS FOR CAUTION: One of the limitations of this study was the early closure and the ongoing PR could be overestimated. Both patient and gynaecologist were informed of the assigned treatment. WIDER IMPLICATIONS OF THE FINDINGS: Our results demonstrated the lack of differences in terms of ongoing PR between recombinant product and HP-hMG, in women ≥35 years undergoing controlled ovarian stimulation for IUI cycles. HP-hMG was safer than recombinant gonadotrophin concerning the risk of OHSS. STUDY FUNDING/COMPETING INTERESTS: None. TRIAL REGISTRATION NUMBER: NCT01604044.

RESUMEN

Psoriasis is a common, chronic, relapsing immune-mediated inflammatory disease (IMID) of the skin. IMIDs are multifactorial diseases characterized by common molecular pathways leading to a systemic inflammation. Patients with an IMID are also at higher risk of developing co-morbidities, such as adverse pregnancy outcomes, than the general population. A higher rate of pregnancy complications have been seen in inflammatory bowel disease and rheumatoid arthritis. The data for psoriasis are inconsistent but it appears that women with moderate-to-severe psoriasis may also have an increased risk of poor pregnancy outcomes. The cause of this association is unknown, although it may be related to elevated proinflammatory cytokines such as IL-6 and TNF-α, the high prevalence of comorbidities and other unhealthy behaviours, or the high prevalence of polycystic ovary syndrome (PCOS). In a recent study, PCOS prevalence in a psoriatic cohort (n = 51) was higher than in non-psoriatic women (n = 102) (47% versus 11%), and women with PCOS and psoriasis had a greater probability of insulin resistance, hyperinsulinaemia, and dyslipidaemia as well as a more severe skin condition, than those with psoriasis alone. Further studies are necessary to clarify the impact of psoriasis on pregnancy and in particular if these effects are mediated by concomitant PCOS.

RESUMEN

OBJECTIVE: To evaluate the influence of phthalates on human luteal cell function. DESIGN: Laboratory study. SETTING: University hospital. PATIENT(S): Twenty-three normally menstruating patients in the midluteal phase. INTERVENTION(S): Human luteal cells isolated from corpora lutea for primary cultures. MAIN OUTCOME MEASURE(S): Progesterone (P4) and prostaglandin release assayed by enzyme immunoassay, vascular endothelial growth factor (VEGF) secretion by enzyme-linked immunosorbent assay (ELISA), and VEGF mRNA expression by real-time polymerase chain reaction. RESULT(S): We investigated the effect of di(2-ethylhexyl)phthalate (DEHP), di-n-butyl phthalate (DBP), and butyl benzyl phthalate (BBP) on basal and hCG-induced progesterone (P4) release, as well as DEHP effect on the balance between prostaglandin (PG) E2, vascular endothelial growth factor (VEGF)-luteotrophic factors, and the luteolitic PGF2α in isolated human steroidogenc cells. Phthalates influence on VEGF expression has been also evaluated. DEHP, DBP, and BBP were able to reduce both basal and hCG-stimulated P4 as well as PGE2 release. PGF2α release was reduced after DEHP incubation. VEGF protein release was decreased by the incubation with the tested phthalates. VEGF mRNA expression was not affected by DEHP, DBP, and BBP. As expected, both hCG and cobalt chloride were able to induce P4 release and VEGF release and mRNA expression in human luteal cells respectively. CONCLUSION(S): The results show the ability of phthalates to affect luteal steroidogenesis as well as the balance between luteotrophic and luteolytic factors suggesting an interference of phthalates in human luteal function. These data may contribute to clarify the classically known impaired reproductive health observed after phthalates exposure.

RESUMEN

OBJECTIVE: To develop and validate a specific simple measure of insulin sensitivity using oral glucose tolerance test (OGTT) values for lean polycystic ovary syndrome (PCOS) women. DESIGN: Retrospective study. SETTING: Gynecologic Outpatient Clinic of University Hospital, affiliated with Unit of Gynecologic Endocrinology. PATIENT(S): Totals of 201 lean and 198 overweight/obese (ov-ob) nondiabetic PCOS patients were retrospectively selected. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): All patients underwent OGTT, euglycemic-hyperinsulinemic clamp, and androgenic and biochemical assays. The predictive performance of each insulin resistance (IR) index was analyzed with the use of receiver operating characteristic (ROC) curves. RESULT(S): Higher correlation coefficients with clamp studies were obtained with the Belfiore Area (RS=0.579) and the homeostasis-model assessment (HOMA)-M120 (RS=-0.576) in lean PCOS patients and with the Sib (RS=0.697) in ov-ob PCOS patients. The best predictive index of IR in lean PCOS was a HOMA-M120 value of ≥12.8 or more (area under the ROC curve [AUC] 92.4%). In the ov-ob PCOS population, the best predictive performance was obtained by a Sib of ≤10.2 or less (AUC 85.7%). CONCLUSION(S): IR should be assessed in all PCOS women, both lean and ov-ob subjects. The HOMA-M120 resulted as a very simple tool, validated specifically for the lean PCOS woman whose cardiometabolic impairment is more frequently misunderstood.

RESUMEN

Endocrine disruptors are well known to impair fertility. The aim of the present study was to investigate the effects of bisphenol A (BPA) and nonylphenol (p-NP) on human luteal function in vitro. In particular, in luteal cells isolated from 21 human corpora lutea progesterone, prostaglandin (PG) F2α, PGE2 and vascular endothelial growth factor (VEGF) release, as well as VEGF expression were evaluated. BPA and p-NP negatively affected both luteal steroidogenesis and luteotrophic/ luteolytic factors balance, without influencing VEGF mRNA expression. Actually, BPA and p-NP impaired human luteal cells function in vitro, underlining the already suggested correlation between phenols and reproductive failure.

RESUMEN

OBJECTIVE: To evaluate the long-term effects of drospirenone (DRSP)/ethinylestradiol (EE) alone, metformin alone, and DRSP/EE-metformin on CD4(+)CD28(null) T lymphocytes frequency, a cardiovascular risk marker, in patients with hyperinsulinemic polycystic ovary syndrome (PCOS). DESIGN: Randomized clinical trial. INTERVENTIONS: Ninety three patients with hyperinsulinemic PCOS were age matched and body mass index matched and randomized to receive a 6 months daily treatment with DRSP (3 mg)/EE (0.03 mg), or metformin (1500 mg), or DRSP/EE combined with metformin. MAIN OUTCOME MEASURES: CD4(+)CD28(null) T-cell frequencies. RESULTS: The DRSP/EE and metformin groups did not show any significant change in the CD4(+)CD28(null) frequency compared to the baseline. Interestingly, a statistically significant decrease in CD4(+)CD28(null) frequency occurred after 6 months of DRSP/EE-metformin (median 3-1.5; P < .01). Of note, this statistically significant association was confirmed after adjusting for baseline values in DRSP/EE-metformin group by analysis of covariance (P < .05). CONCLUSIONS: In women with hyperinsulinemic PCOS, combined therapy with DRSP/EE and metformin may reduce cardiovascular risk.

RESUMEN

OBJECTIVE: To define the prevalence and the features of polycystic ovary syndrome (PCOS) in patients with psoriasis. To our knowledge, the association between PCOS and psoriasis has not been explored in previous studies. Psoriasis is linked with metabolic syndrome, insulin resistance, and non-alcoholic fatty liver disease, which are features often associated with PCOS. DESIGN: A cross-sectional analysis was performed between January 2010 and April 2012. SETTING: Unit of human reproductive pathophysiology, Catholic University Hospital. PATIENT(S): We prospectively analyzed 51 patients with psoriasis and 102 healthy age- and body mass index (BMI)-matched controls. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): The prevalence and characteristics of PCOS women of reproductive age with chronic plaque psoriasis. RESULT(S): The prevalence of PCOS was greater in patients with psoriasis than in matched control subjects (47.05% and 11.76%, respectively; odds ratio, 6.66; 95% confidence interval 2.95-15.07). Among the women with psoriasis, the prevalence of Psoriasis Area and Severity Index ≥10 was higher in patients with PCOS than in subjects without PCOS (odds ratio, 3.5; 95% confidence interval 1.04-11.72). CONCLUSION(S): The prevalence of PCOS in women with psoriasis is remarkably greater than in age- and BMI-matched control women.

RESUMEN

OBJECTIVE: To study the frequency of CD4(+)CD28(null) T cells, which are aggressive T lymphocytes associated with recurrent coronary instability and type 2 diabetes mellitus, in different polycystic ovary syndrome (PCOS) phenotypes and in age- and body mass index-matched healthy women. DESIGN: Retrospective cohort observational study. SETTING: Unit of human reproductive pathophysiology, university hospital. PATIENT(S): A total of 167 PCOS patients and 102 control subjects. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): CD4(+)CD28(null) T cell frequency, high-sensitive C-reactive protein levels, and other glucose-metabolic parameters. RESULT(S): CD4(+)CD28(null) frequency was significantly higher in all PCOS groups than in control subjects. CD4(+)CD28(null) frequency was significantly higher in nonhyperandrogenic phenotype (5.7%, range 3.2-7.1) than in phenotypes with hyperandrogenism (H) + oligoamenorrhea (O) + polycystic ovary (PCO) (3.5%, range 1-5.8), H + O (3%, range 1.8-4.7), and H + PCO (2.63%, range 1.2-4.1). The relative risk of non-H phenotype for PCOS women in the highest quartile for CD4(+)CD28(null) frequency compared with PCOS women with the lowest quartile was 3.2 (95% confidence interval 1.9-5.8). CONCLUSION(S): Cardiovascular risk evaluation should be performed in all PCOS phenotypes. In particular, we demonstrated that the non-H phenotype has potentially increased cardiovascular risk in terms of CD4(+)CD28(null) frequency.

RESUMEN

OBJECTIVE: To evaluate whether unacylated ghrelin and obestatin were able to influence human luteal cell function. The effect of these two ghrelin-related peptides on progesterone (P4), prostaglandin (PG) F(2α), PGE(2), and vascular endothelial growth factor (VEGF) release and on VEGF expression in isolated human steroidogenic cells has been investigated. DESIGN: Prospective laboratory study. SETTING: University hospital. PATIENT(S): Corpora lutea were obtained from 23 normally menstruating patients in the midluteal phase of the menstrual cycle. INTERVENTION(S): Human luteal cells were isolated from corpora lutea, and primary cultures were established. MAIN OUTCOME MEASURE(S): P4 and PGs release was assayed by enzyme immunoassay, VEGF secretion by ELISA, and VEGF mRNA expression by real-time polymerase chain reaction. RESULT(S): P4 and VEGF release were significantly reduced by both unacylated ghrelin and obestatin. Moreover, the highest concentration of obestatin was able to reduce the release of PGE(2) and PGF(2α). VEGF mRNA expression was not affected by the incubation with any of these ghrelin-related peptides. As expected, CoCl(2) was able to induce VEGF release and mRNA expression in luteal cells. CONCLUSION(S): Our results suggest that, similar to ghrelin, both unacylated ghrelin and obestatin might play a role in regulating the luteal cell function that affects both luteal steroidogenesis and luteotrophic/luteolytic imbalance. These results further underline the pivotal correlation between the ghrelin system and reproduction.

RESUMEN

OBJECTIVE: The objective of this study is to determine the ability of metformin treatment in reducing the prevalence of metabolic syndrome (MS) and its hepatic involvement in young hyperinsulinaemic overweight patients with polycystic ovarian syndrome (PCOS). DESIGN: Clinical Trial. PATIENTS: We recruited 140 hyperinsulinaemic overweight women with PCOS in their reproductive age. Metformin treatment (500 mg × 3/die) was prescribed to each patient for twelve months. MEASUREMENTS: The primary outcome was to evaluate the prevalence of nonalcoholic fatty liver disease (NAFLD) and MS in hyperinsulinaemic overweight patients with PCOS. The secondary outcome was to evaluate, in the same patients, the effects of metformin therapy on endocrine, metabolic and hepatic parameters. RESULTS: At basal evaluation, NAFLD was diagnosed in 81 of 140 patients with PCOS (57·85%); MS was present only in the NAFLD group (32·09%vs 0%; P < 0·001). After twelve months, metformin is able to significantly reduce, in the same group, the prevalence of MS (28·9%vs 13·5%; P < 0·01). An improvement of hepatic parameters and a significant decrease in oligomenorrhea (85·7%vs 19%, P < 0·001) were also observed. CONCLUSIONS: Treatment with metformin is indicated in all hyperinsulinaemic overweight patients with PCOS, especially in those with NAFLD. These data appear even more interesting considering their increased risk to develop metabolic and hepatic complications.

RESUMEN

Women affected by polycystic ovary syndrome (PCOS) have an increased risk of cardiovascular disease. We demonstrated that women with PCOS showed an expansion of CD4(+)CD28(null) T cells, an aggressive population of T lymphocytes that has been recently associated with recurrent coronary instability and type 2 diabetes mellitus. This sheds new light on possible mechanisms responsible for the higher rate of cardiovascular disease among women with PCOS.
