  • Chronic endometritis and altered embryo implantation: a unified pathophysiological theory from a literature systematic review

    Giovanni Buzzaccarini, Amerigo Vitagliano, Alessandra Andrisani, Carla Mariaflavia Santarsiero, Rossana Cicinelli, Claudia Nardelli, Guido Ambrosini, Ettore Cicinelli

    Chronic endometritis (CE) is a frequent hysteroscopic and histological finding which affects embryo transfer implantation during IVF-ICSI cycles. In particular, CE impairs proper decidualization and, subsequently, implantation. Although this correlation has been clearly clarified, a pathophysiological explanation assembling all the studies performed has not been elucidated yet. For this reason, we have structured a systematic review considering all the original articles that evaluated a pathological element involved in CE and implantation impairment.

  • Middle Cerebral Artery Peak Systolic and Ductus Venosus Velocity Waveforms in the Hydropic Fetus

    Erich Cosmi, Salvatore Dessole, Luisa Uras, Giampiero Capobianco, Donato D’Antona, Alessandra Andrisani, Pietro Litta, Guido Ambrosini

    The purpose of this study was to assess whether Doppler assessment of the middle cerebral artery (MCA) peak systolic velocity (PSV) and ductus venosus (DV) velocity waveforms during sonography of hydropic fetuses may specify the cause of fetal hydrops.

  • Role of Renin-Angiotensin-Aldosterone System and Cortisol in Endometriosis: A Preliminary Report

    Chiara Sabbadin, Carlo Saccardi, Alessandra Andrisani, Amerigo Vitagliano, Loris Marin, Eugenio Ragazzi, Luciana Bordin, Guido Ambrosini, Decio Armanini

    Endometriosis is a chronic inflammatory disease associated with pelvic pain, infertility, and increased cardiovascular risk. Recent studies suggest a possible role of aldosterone as a pro-inflammatory hormone in the pathogenesis of the disease. Cortisol is also an important mediator of stress reaction, but its role is controversial in endometriosis. The aim of this study was to evaluate aldosterone and cortisol levels and blood pressure values in women with endometriosis. We measured blood pressure, plasma aldosterone, renin, cortisol, and dehydroepiandrosterone sulfate (DHEAS) in 20 women with untreated minimal or mild pelvic endometriosis compared with 20 healthy controls matched for age and body mass index. Aldosterone values were similar in the two groups, while renin was significantly lower and the aldosterone to renin ratio was significantly higher in patients with endometriosis than in controls. Systolic blood pressure was in the normal range, but significantly higher in patients with endometriosis. Morning plasma cortisol was normal, but significantly lower in patients with endometriosis compared with controls, while DHEAS to cortisol ratio was similar in the two groups. These preliminary results are evidence of increased biological aldosterone activity and dysregulation of the hypothalamic-pituitary-adrenal axis in early stages of endometriosis. These alterations could play a role in disease development, suggesting new therapeutic targets for aldosterone receptor blockers.

  • Uterine Septum with or without Hysteroscopic Metroplasty: Impact on Fertility and Obstetrical Outcomes-A Systematic Review and Meta-Analysis of Observational Research

    Marco Noventa, Giulia Spagnol, Matteo Marchetti, Carlo Saccardi, Giulio Bonaldo, Antonio Simone Laganà, Francesco Cavallin, Alessandra Andrisani, Guido Ambrosini, Salvatore Giovanni Vitale, Luis Alonso Pacheco, Sergio Haimovich, Attilio Di Spiezio Sardo, Jose Carugno, Marco Scioscia, Simone Garzon, Stefano Bettocchi, Giovanni Buzzaccarini, Roberto Tozzi, Amerigo Vitagliano

    We performed a systematic review/meta-analysis to evaluate the impact of septate uterus and hysteroscopic metroplasty on pregnancy rate-(PR), live birth rate-(LBR), spontaneous abortion-(SA) and preterm labor (PL) in infertile/recurrent miscarriage-(RM) patients. Data sources: a literature search of relevant papers was conducted using electronic bibliographic databases (Medline, Scopus, Embase, Science direct). Study eligibility criteria: we included in this meta-analysis all types of observational studies that evaluated the clinical impact of the uterine septum and its resection (hysteroscopic metroplasty) on reproductive and obstetrics outcomes. The population included were patients with a diagnosis of infertility or recurrent pregnancy loss. Study appraisal and synthesis methods: outcomes were evaluated according to three subgroups: (i) Women with untreated uterine septum versus women without septum (controls); (ii) Women with treated uterine septum versus women with untreated septum (controls); (iii) Women before and after septum removal. Odds ratios (OR) with 95% confidence intervals (CI) were calculated for the outcome measures. A p-value < 0.05 was considered statistically significant. Subgroup analysis was performed according to the depth of the septum. Sources of heterogeneity were explored by meta-regression analysis according to specific features: assisted reproductive technology/spontaneous conception, study design and quality of papers included Results: data from 38 studies were extracted. (i) septum versus no septum: a lower PR and LBR were associated with septate uterus vs. controls (OR 0.45, 95% CI 0.27−0.76; p < 0.0001; and OR 0.21, 95% CI 0.12−0.39; p < 0.0001); a higher proportion of SA and PL was associated with septate uterus vs. controls (OR 4.29, 95% CI 2.90−6.36; p < 0.0001; OR 2.56, 95% CI 1.52−4.31; p = 0.0004). (ii) treated versus untreated septum: PR and PL were not different in removed vs. unremoved septum(OR 1.10, 95% CI 0.49−2.49; p = 0.82 and OR 0.81, 95% CI 0.35−1.86; p = 0.62); a lower proportion of SA was associated with removed vs. unremoved septum (OR 0.47, 95% CI 0.21−1.04; p = 0.001); (iii) before-after septum removal: the proportion of LBR was higher after the removal of septum (OR 49.58, 95% CI 29.93−82.13; p < 0.0001) and the proportion of SA and PL was lower after the removal of the septum (OR 0.02, 95% CI 0.02−0.04; p < 0.000 and OR 0.05, 95% CI 0.03−0.08; p < 0.0001) Conclusions: the results show the detrimental effect of the uterine septum on PR, LBR, SA and PL. Its treatment reduces the rate of SA.
