A prospective randomized clinical trial is needed to confirm our findings but in women with RIF a hysteroscopic evaluation of the uterine cavity to exclude CE should be considered and appropriate antibiotic treatment should be given before submitting the patient to a further IVF attempt.

Recurrent miscarriage (RM) is defined as 3 or more miscarriages before 20 weeks' pregnancy. In recent years, interest has been focused on chronic endometritis (CE), a subtle inflammation thought to be associated with RM. We aimed to evaluate the relationships between CE and RM. The records of 360 women with unexplained RM were retrospectively analyzed. Data from hysteroscopy, endometrial histology, endometrial culture, and polymerase chain reaction for chlamydia, performed before and after antibiotic treatment for CE, were analyzed. The occurrence of successful pregnancies within 1 year after treatment was also evaluated. Results showed that 208 (57.8%) women with RM showed CE at hysteroscopy; 190 (91.3%), positive at hysteroscopy, were also positive at histology, and 142 (68.3%) had positive cultures. Common bacteria were found in 110 (77.5%) patients. Mycoplasma and Ureaplasma were found in 36 (25.3%) patients and Chlamydia in 18 patients (12.7%). In 102 (71%) women, antibiogram-based antibiotic treatment normalized hysteroscopy, histology, and cultures (group 1); while in 40 (28.2%) patients, CE was still present at hysteroscopy (group 2). In 16 of the 66 patients positive at hysteroscopy, but not at cultures, the hysteroscopy becomes normal (group 3) after a Centers for Disease Control and Prevention-based therapy; while in 50 women, CE was still present (group 4). One year after treatment, group 1 showed a significantly higher number of pregnancies (78.4%) compared to group 2 (17.5%; P < .001) and group 4 (15.3%; P = .005). The CE is frequent in women with RM. Antibiotic treatment seems to be associated with an improved reproductive outcome.

Chronic endometritis is highly prevalent in patients with unexplained infertility. Diagnosis and treatment of chronic endometritis improve spontaneous pregnancy rate and live birth rate in such patients.

ObjectiveOvarian senescence affects many tissues and produces a variety of symptoms and signs. We hypothesized that estrogens may also influence circulating redox balance by regulating activity of the cellular antioxidative enzyme system. We aimed to explore the impact of surgical estrogen deprivation and replacement (ERT) on the glutathione balance and antioxidant enzymes expression in fertile women.Study designNineteen healthy premenopausal women who underwent total hysterectomy with bilateral salpingo-oophorectomy were evaluated at baseline, 30 days after surgery without ERT and 30 days after ERT. Redox balance was determined by measuring blood reduced (GSH) and oxidized (GSSG) glutathione, as well as the GSSG/GSH ratio. Antioxidant status was evaluated by measuring serum estrogen (E2) levels and mRNA expression of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px) and glutathione S-transferase (GST) in peripheral blood mononuclear cells.ResultsSerum E2 significantly lowered after surgery, and increased in 12 out of 19 patients after 30 days of ERT (Responders). In such patients, an increase in oxidative stress was observed after surgery that resolved after ERT. Oxidative stress was sustained by reduction in the mRNA expression of both SOD and GSH-Px, that recovered after 30 days of therapy in responders. CAT and GST mRNA expression were not modified by surgery and replacement therapy.ConclusionsMenopause is associated with significant change in antioxidant gene expression that in turn affects circulating redox state. Estrogens replacement therapy is able to prevent and counteract such modifications by acting as regulators of key antioxidant gene expression. These findings suggest that antioxidant genes are, almost in part, under the control of sex hormones, and that pathophysiology of the difference in gender disease may depend on the redox biology.

Infertile women with CE showed an abnormal percentage of endometrial lymphocyte subsets compared with unexplained infertile women suggesting that different mechanisms underlie the adverse pregnancy outcome of the two groups of patients.

Objective To evaluate the efficacy and safety of topical anaesthesia in reducing pain and incidence of vasovagal reactions during diagnostic hysteroscopy with endometrial biopsy in postmenopausal women.Design Randomised placebo-controlled double-blind study. Setting University hospital.Participants Eighty postmenopausal women undergoing diagnostic hysteroscopy and endometrial biopsy.Interventions Two millilitres of 2% mepivacaine or saline solution were injected transcervically into the uterine cavity before performing the procedures.Main outcome measures Evaluation of pain reduction on a visual analogue scale and continuous monitoring of heart rate and blood pressure. ResultsThe use of the anaesthetic significantly reduced the pain experienced at hysteroscopy and endometrial biopsy. The occurrence of vasovagal reactions was significantly lower in the anaesthetised group.Conclusions Topical anaesthesia attenuated pain and effectively prevented the occurrence of vasovagal reactions during hysteroscopy and endometrial biopsy in postmenopausal women.
