Prevalence of metabolic syndrome and its components in women with and without pelvic organ prolapse and its association with prolapse severity according to the Pelvic Organ Prolapse Quantification system.
No full textINTRODUCTION AND HYPOTHESIS:
Data regarding possible associations between metabolic syndrome (MS) and pelvic organ prolapse (POP) are scarce. The primary hypothesis was that the prevalence of MS and its components was higher in postmenopausal women with POP than in age-matched women without POP staged with the Pelvic Organ Prolapse Quantification system (POP-Q). The secondary aim of the study was to analyze the association between MS and its components with POP severity.
METHODS:
Presence of MS and its components [elevated triglycerides (TG), waist circumference, blood pressure, and fasting glucose (FG) and decreased high-density lipoprotein cholesterol (HDL-C)] were assessed in 122 women with POP (POP-Q stage I-IV) and 77 without (POP-Q 0). Fasting insulin resistance [homeostasis model assessment for fasting insulin resistance (HOMA-IR)] was also assessed.
RESULTS:
TG levels, FG, and HOMA index were significantly higher in POP-Q stage I-IV compared with POP-Q 0 (p = 0.04, p = 0.0005 and p = 0.04); HDL-C was significantly reduced in POP-Q stage I-IV compared with POP-Q 0 (p = 0.0003). TG levels (p = 0.0315) were significantly higher in POP-Q stage III and IV vs. POP-Q 0; FG and HOMA-IR (p = 0.0015 and p = 0.0204) were significantly higher in POP-Q stage IV vs. POP-Q 0; HDL-C (p = 0.0047) was significantly lower in all stages vs. POP-Q 0. The prevalence of MS was different between groups (p = 0.04) and higher in POP-Q IV. Elevated TG [odds ratio (OR) 4.6, 95% confidence interval (CI) 1.5-9.3, p = 0.004] and reduced HDL-C (OR 2.0, 95% CI 1.1-3.7, p = 0.0241) significantly increased the risk of POP-Q stage ≥III.
CONCLUSIONS:
MS and its components may be associated with POP. Elevated TG and reduced HDL-C are associated with POP severity
Bone Mineral Density in Women Living with Complete Androgen Insensitivity Syndrome and Intact Testes or Removed Gonads.
No full textComplete androgen insensitivity syndrome (CAIS) is due to complete androgen resistance in androgen-dependent tissues. Since androgens are involved in growth, development, and mass maintenance of the skeleton, bone health may be a relevant clinical issue for improving quality of life of women living with CAIS. Bone mineral density (BMD) in women with CAIS and intact gonads has been reported in a normal range, although exceptions are known showing a low BMD mainly at the lumbar level. In women with CAIS and removed gonads, BMD is usually reduced at both the lumbar spine and femoral neck. However, the fracture risk remains largely unknown. In women with CAIS, hormonal replacement therapy may improve BMD, but it does not normalize it. Several factors may be operative (e.g., loss of AR signaling at the bone level, gonadal removal, and age at surgery [before or after attainment of the peak bone mass], inadequate sex steroid replacement therapy, poor compliance with hormonal treatment, high serum FSH levels, lack of testicular protein hormones after gonadal removal), but they are poorly evaluated. In conclusion, the maintenance of testes may represent a strategy to improve bone health in women with CAIS, but a strict follow-up to monitor the cancer risk is mandatory mainly from their 20s onwards. Optimal sex steroid substitutive therapy in adolescence and adulthood is a key factor to improve BMD status in women with CAIS and removed gonads, but conclusive data on optimal management are lacking
Insulin-like factor 3: A novel circulating hormone of testis origin in humans
No full textInsulin-like factor 3 (INSL3) is a member of the relaxin-insulin family, and it is expressed in pre- and postnatal Leydig cells of the testis. This peptide affects testicular descent during embryonic development, and mutations in INSL3 gene or its receptor LGR8 (leucine-rich repeat-containing G protein-coupled receptor 8)/GREAT (G protein-coupled receptor affecting testicular descent) cause cryptorchidism in humans. The expression of LGR8/GREAT in different tissues and the production of INSL3 also by adult-type Leydig cells suggest additional roles of this hormonal system in adulthood. In this preliminary report we performed the first analysis in humans of INSL3 using a novel RIA kit to measure INSL3 concentrations in serum of normal men and with different testicular pathologies. The results show that INSL3 is circulating in adult men, and it is almost exclusively of testicular origin. Subjects with severe testicular damage, such as men with severe infertility, produce low amount of INSL3, and the concentrations of this hormone seem to reflect the functional status of the Leydig cells. In particular, INSL3 concentrations may be an even more sensitive marker of Leydig cell function than testosterone itself. Analysis of men treated with different combinations of hormones of the hypothalamus-pituitary-testis axis suggests that the production of INSL3 is related to LH in a manner similar to that of the LH-testosterone axis

Effects of ospemifene on vaginal epithelium of post-menopausal women.
No full textOspemifene is a selective estrogen receptor modulator used for the treatment of vulvo-vaginal atrophy (VVA) in post-menopausal women. No direct evidence of its effects on histological features of the human vagina has been reported. To evaluate the effects of ospemifene on histological parameters, glycogen content, proliferation, and estrogen receptor α expression (ERα) of vaginal epithelium in post-menopausal women. Thirty-two post-menopausal women undergoing surgical procedures were enrolled. Sixteen subjects taking ospemifene at the time of inclusion (OSP) were compared to 16 subjects not taking any hormone (CTL). Vaginal biopsies were taken from the proximal and distal vaginal wall during surgery to evaluate histology, Ki-67 and ERα expression. OSP group showed thicker vaginal epithelium (349 ± 64 vs. 245 ± 53 μm, p < .001), higher proliferation index (212 ± 47 vs. 127 ± 28 Ki-67+ cells/mm, p < .001), higher epithelial (27.3 ± 3.1 vs. 20.6 ± 2.9 score, p < .001) and stromal (26.6 ± 4.9 vs. 20.6 ± 2.6 score, p < .001) ERα expression when compared to the CTL group. In postmenopausal women affected by VVA, 1 month intake of ospemifene is associated with an increased maturation, and ERα expression of the vaginal mucosa. These changes may partially explain the improvement of symptoms of vaginal atrophy reported with this drug
Presentation of a meningioma in a transwoman after nine years of cyproterone acetate and estradiol intake: case report and literature review.
No full textThe administration of cyproterone acetate (CPA) and estradiol is a common regimen used by male-to-female transsexuals (transwoman) to adjust their body to their gender identity. Major adverse events are uncommon in these subjects in spite of long-term, high dose cross-sex steroid treatments. We describe the occurrence of a meningioma in a transwoman treated with estrogens and CPA over a period of nine years. The meningioma was revealed during a magnetic resonance imaging (MRI) scan performed as follow-up of a previous surgery for ganglioglioma. CPA intake was discontinued and tumor resection was performed. Histological diagnosis confirmed a strong progesterone receptor-positive and slight estrogen positive meningioma. After surgery, the patient continued her treatment with leuprorelina acetate and estradiol. At one-year follow-up, the MRI scan reveals no recurrence of the tumor. This is the ninth case in literature of a meningioma in a transwoman treated with estrogens and CPA, confirming a possible association between female sex steroids and meningioma. Although there is no still strong evidence of an association between meningioma and CPA, this report may suggest use of alternative treatment for transwomen. This report highlights the importance to record all the cases of meningiomas in high dose CPA-users, in order to improve dat
Structure of Epithelial and Stromal Compartments of Vulvar and Vaginal Tissue From Women With Vulvo-Vaginal Atrophy Taking Ospemifene.
No full textINTRODUCTION:
Vulvo-vaginal atrophy affects the daily lives of most post-menopausal women. We know that ospemifene intake can induce vaginal epithelial improvements within a few weeks; however, direct evidence of the effects of ospemifene on the human vulva and on connective tissue of both the vagina and vulva are lacking.
AIM:
To evaluate the changes induced by ospemifene on epithelium thickness, glycogen content proliferation index, collagen content, and type I/III collagen ratio in vulvar and vaginal tissue of post-menopausal women.
METHODS:
20 women who attended our gynecologic clinic for planned surgery were recruited for the study. 11 subjects were taking ospemifene at the time of inclusion, and 9 subjects who were not taking ospemifene were selected as control group. Vaginal and vulvar biopsies were taken during surgery. Histological features and glycogen content were evaluated by standard hematoxylin-eosin and periodic acid-Schiff staining, total collagen and collagen type I/III ratio were evaluated by hydroxyproline assay and Sirius red staining, while the expression of Ki67 was evaluated by immunohistochemistry.
MAIN OUTCOME MEASURE:
We analyzed histological features of the epithelial and stromal layer of the vaginal and vulvar vestibule mucosa.
RESULTS:
Vaginal and vulvar biopsies from women taking ospemifene showed an increased epithelium thickness, glycogen content, and proliferation index compared with the control group. Collagen content was also higher in women taking ospemifene, while an increased ratio between type I and III collagen fibers was found only at vaginal level.
CLINICAL IMPLICATIONS:
Our study shows that the effectiveness of ospemifene on vaginal tissue also extends to the vulvar vestibule.
STRENGTH & LIMITATIONS:
This study provides direct evidence of the impact of ospemifene on vaginal and vulvar tissue. A specifically designed longitudinal study may further support our findings.
CONCLUSION:
Ospemifene intake is associated with a marked improvement of various morphological and physiological features of both vaginal and vulvar vestibule epithelium, including the collagen content of the tissues
Testosterone undecanoate and testosterone enanthate injections are both effective and safe in transmen over 5 years of administration.
No full textOBJECTIVE:
To retrospectively evaluate and compare safety and efficacy of short and long-acting testosterone (T) parenteral formulations over 5 years in transmen.
DESIGN AND METHODS:
Fifty transmen between 21 and 42 years of age were enrolled. Twenty-five received T undecanoate 1000 mg IM (weeks 0 and 6 then every 12-16 weeks), and 25 received T enanthate 250 mg IM (every 3-4 weeks). Hormonal and biochemical parameters, anthropometric characteristics and blood pressure were assessed at baseline and then every 12 months. Body composition was evaluated at baseline and then after 1, 3 and 5 years of T treatment. Global satisfaction was assessed at baseline and after 1 and 5 years.
RESULTS:
Both T formulations led to amenorrhoea in all subjects within 1 year of T administration. Both T treatments led to a similar increase in haemoglobin and haematocrit which always remained within the physiological range. T administration was associated with an increase in total cholesterol, low-density lipoprotein cholesterol and triglycerides and a slight reduction in high-density lipoprotein cholesterol. Coagulative and glucidic profiles and blood pressure did not change significantly in either group. Body weight and BMI showed a slight but not significant increase in both groups, while lean mass rose significantly in both groups. Global satisfaction was increased at years 1 and 5 in both groups.
CONCLUSIONS:
Preliminary results from this pilot study suggest that administration of either TU or TE for 5 years in young transmen is both effective and safe. Our study presents the longest follow-up published so far reporting no adverse events and these data are consistent with previous reports with a shorter follow-up
