Increased antinuclear (anti-Sm) antibodies in infertile patients with peritoneal endometriosis.

Objective: The aim of this study is to evaluate the intensity of five antibodies against extractable nuclear antigens (ENA: RNP, ScL-70, SS-B, SS-A, and Sm) in infertile patients with endometriosis.

Methods: We investigated infertile women with minimal/mild endometriosis (n=43) and fertile women (n=46).

Results: The intensity of immunoreactions was also similar for anti-RNP and anti-SS-A antibodies.

Transforming growth factor beta-1 (TGF-β1) expression in patients with adenomyosis.

Objective: To compare Transforming growth factor beta-1 (TGF-β1) expression in patients with and without adenomyosis.

Methods: A prospective design was performed including 49 patients submitted to hysterectomy. Immunohistochemistry was performed on anatomopathological samples staged in paraffin blocks from patients with and without adenomyosis.

Follicular fluid concentration of soluble Human-G Leukocytic Antigen (sHLA-G) in in vitro fertilization cycles of women with and without peritoneal endometriosis.

Objective: The objective of this research is to investigate the association between the concentrations of soluble human leukocyte G antigen (sHLA-G) in the follicular fluid (FF) in infertile patients with peritoneal endometriosis submitted to in vitro fertilization.

Methods: We performed a cross-sectional study, including ninety-six women undergoing in vitro fertilization (IVF) ageing ≤ 40 years. Infertile patients were classified into two groups: with endometriosis diagnosed by laparoscopy and without endometriosis due to tubal factor.

The Graduated Embryo Score of Embryos from Infertile Women with and without Peritoneal Endometriosis.

Objective:  To determine embryo quality (mean graduated embryo score [GES]) in infertile patients with endometriosis undergoing in vitro fertilization with embryo transfer (IVF-ET) compared with infertile patients without endometriosis.

Methods:  A case-control study was performed comparing 706 embryos (162 patients) divided into 2 groups: 472 embryos derived from patients without endometriosis ( = 109, infertile patients with tubal infertility) and 234 embryos from patients in the study group ( = 53, infertile patients with peritoneal endometriosis). All patients were subjected to IVF using an oestradiol-antagonist-recombinant follicle-stimulating hormone (FSH) protocol for ovarian stimulation.

Randomized controlled trial comparing embryonic quality in rFSH versus hMG in the IVF protocol with GnRH Antagonist.

Objective: The aim of the present study is to investigate embryo quality (score) after controlled ovarian stimulation for IVF using rFSH or hMG with the GnRH antagonist protocol.

Methods: Open, randomized, single center study. The patients were randomized to receive rFSH or hMG according to randomized cards inside a black envelope with the name of the respective treatment following a computer generated list (85 patients were allocated to rFSH group and 83 patients to hMG group).

PIWIL2 is overexpressed in adenomyotic lesions of women with diffuse adenomyosis.

Purpose: Adenomyosis has been studied throughout the years, however, its aetiology and physiopathology are still unknown. The aim of this study was to identify the presence of PIWI proteins in women with adenomyosis.

Methods: We included 72 participants to be part of this study and were divided into two groups based on their anatomopathological diagnosis, control (n = 36) or adenomyosis (n = 36).

Diclofenac versus a combination of hyoscine and diclofenac for outpatient hysteroscopy: A placebo controlled randomized clinical trial.

Objective: to compare the effect of administering diclofenac sodium and/or oral hyoscine in pain perception during and after outpatient diagnostic hysteroscopy without anesthesia.

Study Design: a randomized, double-blind placebo-controlled clinical trial was performed in an University Hospital. We included 217 patients submitted to office hysteroscopy for the following indications: diagnosis of abnormal uterine bleeding, endometrial polyps, submucous myomas, infertility and recurrent miscarriage.

Correlations among algometry, the visual analogue scale, and the numeric rating scale to assess chronic pelvic pain in women.

Objective: To investigate the correlation between the numerical rating scale, visual analogue scale, and pressure threshold by algometry in women with chronic pelvic pain.

Study Design: This was a cross-sectional study. We included 47 patients with chronic pelvic pain.

LH (Trp8Arg/Ile15Thr), LHR (insLQ) and FSHR (Asn680Ser) polymorphisms genotypic prevalence in women with endometriosis and infertility.

Purpose: To verify if polymorphisms of LH (Trp8Arg/Ile15Thr), LH receptor (insLQ), and FSH receptor (Asn680Ser) are associated with endometriosis and infertility.

Methods: This is a prospective case-control study. Sixty-seven patients with endometriosis and infertility (study group) and 65 healthy fertile patients (control group) were enrolled in the study between July 2010 and July 2013.

Serum prolactin and CA-125 levels as biomarkers of peritoneal endometriosis.

Background/aims: To evaluate serum prolactin and CA-125 levels as biomarkers for the diagnosis of peritoneal endometriosis.

Methods: A prospective study was performed. Blood samples were drawn from a peripheral vein during the secretory phase of the menstrual cycle (day 19-21 prior to the surgery) to analyze through relative operating characteristic curve the serum prolactin and CA-125 levels for diagnosis of peritoneal endometriosis.

ESR1 rs9340799 is associated with endometriosis-related infertility and in vitro fertilization failure.

Estrogen receptor alpha has a central role in human fertility by regulating estrogen action in all human reproductive tissues. Leukemia inhibitory factor (LIF) expression, a cytokine critical for blastocyst implantation, is mediated by estrogen signaling, so we hypothesized that ESR1 gene polymorphisms might be candidate risk markers for endometriosis-related infertility and in vitro fertilization (IVF) failure. We included 98 infertile women with endometriosis, 115 infertile women with at least one IVF failure and also 134 fertile women as controls.

Office hysteroscopy study in consecutive miscarriage patients.

Objective: To assess the prevalence of uterine anatomical abnormalities found by office diagnostic hysteroscopy in a population of patients experiencing more than two consecutive miscarriages and compare the prevalence of uterine abnormalities between patients with two miscarriages and those with three or more consecutive miscarriages.

Methods: A cross-sectional study of 66 patients with two or more consecutive miscarriages diagnosis was conducted. Patients were divided into two groups: Group A (up to two miscarriages, 23 patients), and Group B (3 miscarriages, 43 patients).

There is no complete linkage between the polymorphisms N680S and T307A of the follicular stimulating hormone receptor gene in fertile women.

Purpose: We conducted a cross-sectional study to evaluate the linkage of FSHR T307A and N680S in a group of fertile women.

Methods: Peripheral blood was obtained from 51 fertile women. DNA extraction and isolation were performed.

[Follicle stimulating hormone as predictor of mobile spermatozoa in testicular biopsy of azoospermic patients].

Objective: To define predictive factors of mobile spermatozoa recovery in azoospermic patients.

Methods: Testicular volume, serum follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL) and testosterone levels were assessed in 60 azoospermic patients. Patients underwent bilateral testicular biopsy with local anesthesia.
