RESUMEN
OBJECTIVE: To evaluate the efficacy of a levonorgestrel 52-mg intrauterine system (LNG 52-mg IUS) in controlling abnormal uterine bleeding and improving quality of life in women with inherited bleeding disorders. STUDY DESIGN: We assessed 20 participants laboratory diagnosed with inherited bleeding disorders, who presented with abnormal uterine bleeding and were registered in a Central Blood Center. The primary outcomes were menstrual bleeding volume and quality of life before and after LNG 52-mg IUS placement. We used the Pictorial Blood Loss Assessment Chart (PBAC) score for measuring menstrual bleeding and the Short Form-36 Health Survey to assess quality of life before and after LNG 52-mg IUS placement. We also conducted blood tests to evaluate the hematimetric level. Follow-up visits were conducted at 1, 3, 6, and 12 months after LNG 52-mg IUS placement. Statistical analyses were performed using the Friedman non-parametric test. RESULTS: The use of LNG 52-mg IUS reduced uterine bleeding in women with inherited bleeding disorders. The median PBAC score was higher before LNG 52-mg IUS placement than at 3, 6, and 12 months after placement (p < 0.001). The amenorrhea rate was 70% after 12 months. There was an improvement in all eight parameters of quality of life (p < 0.001). The mean hemoglobin, ferritin, and serum iron levels were also higher at 12 months than before LNG 52-mg IUS placement. CONCLUSION: LNG 52-mg IUS placement can effectively control abnormal uterine bleeding in women with inherited bleeding disorders and consequently improve their quality of life. IMPLICATIONS: The results from our study suggest that women with inherited bleeding disorders who present with heavy menstrual bleeding can benefit from the use of a levonorgestrel-releasing intrauterine system similar to women without bleeding disorders.

PURPOSE: Non-alcoholic fatty liver disease (NAFLD) is an insidious pathologic condition that can manifest from simple steatosis to steatohepatitis (NASH) with potential progression to cirrhosis. Like the polycystic ovary syndrome (PCOS), NAFLD is associated with obesity, diabetes mellitus, insulin resistance and metabolic syndrome. PCOS women have an increased risk of NAFLD, but it is debatable which features of PCOS, either specific (androgen excess) or unspecific (metabolic derangements) affect the NAFLD risk. METHODS: We performed a systematic review and meta-analysis of studies that addressed the association of PCOS and NAFLD. We selected 17 studies published between 2007 and 2017 that included 2734 PCOS patients and 2561 controls of similar age and body mass index (BMI). RESULTS: PCOS patients have increased prevalence of NAFLD (odds ratio 2.54, 95% confidence interval 2.19-2.95). PCOS women with hyperandrogenism (classic phenotype) have a higher prevalence of NAFLD compared to women with PCOS without hyperandrogenism, even after correction for confounding variables. Among women with PCOS, those with NAFLD have higher serum total testosterone (mean difference 0.40 nmol/L, 95% CI 0.29-0.50 nmol/L) and free androgen index (mean difference 4.46, 95% CI 3.53-5.39) than those without NAFLD. The studies that used multivariate analysis controlling for age, BMI, triglycerides, and insulin resistance index confirmed that serum androgens are independent predictors of NAFLD in women with PCOS. CONCLUSION: The prevalence of NAFLD is increased in women with PCOS and the presence of NAFLD is associated with high serum androgen levels, in addition to obesity and insulin resistance.

The rate of motile sperm recovery after cryopreservation is very variable and difficult to predict. Anti-Müllerian hormone (AMH) and inhibin B are produced by Sertoli cells and released into the seminal plasma, where they could be functional markers of spermatogenesis and sperm resistance to thermal stress. The aim of this study was to evaluate whether seminal plasma levels of AMH and inhibin B predict sperm recovery after cryopreservation. The study included 153 men enrolled prospectively during a semen analysis. The cohort was stratified by the fresh semen characteristics into: normal (n = 52), high sperm count (n = 55), asthenozoospermia (n = 23), and oligozoospermia (n = 23). The main outcome measure was motile sperm recovery rate, defined as post-thaw total motile sperm count × 100/pre-freezing total motile sperm count. In men with asthenozoospermia there was a significant correlation between motile sperm recovery rate and the pre-freezing concentrations of AMH (r = 0.522, p < 0.05) and inhibin B (0.471, p < 0.05). In this group, the areas under the receiver operating characteristic curves of AMH and inhibin B for prediction of ≥50% motile sperm recovery after cryopreservation were, respectively, 0.808 and 0.638. AMH was particularly useful, with sensitivity of 0.85, specificity of 0.80, positive predictive value of 0.84 and negative predictive value of 0.80. The sensitivity, specificity, positive, and negative predictive values of inhibin B for the same outcome were, respectively, 0.62, 0.60, 0.67, and 0.55. The median motile sperm recovery rate was 83% when seminal plasma AMH concentration was ≥0.84 ng/mL, vs. 27% when AMH concentration was <0.84 ng/mL (p < 0.05). In other patient groups, there was no correlation between the two hormone levels in seminal plasma and the motile sperm recovery rate. In conclusion, seminal plasma AMH and inhibin B concentrations correlate with and can be used to predict motile sperm recovery after semen cryopreservation in asthenozoospermic men.
