Transforming growth factor beta-1 (TGF-ß1) expression in patients with adenomyosis.

Objective: To compare Transforming growth factor beta-1 (TGF-ß1) 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. The sample contained 28 adenomyosis cases and 21 controls. Student's t-test and multivariate logistic regression tests were used for statistical analysis. Associations were considered significant at p < 0.05. Results: We found no significant association between adenomyosis and: smoking (p = 0.75), miscarriage (p = 0.29), number of previous pregnancies (p = 0.85), curettage (p = 0.81), pelvic pain (p = 0.72) and myoma (p = 0.15). However, we did find a relationship between adenomyosis and abnormal uterine bleeding (AUB) (p = 0.02) and previous cesarean section (p = 0.02). The mean TGF-ß1 intensity (mean ± SD) in the ectopic endometrium of women with adenomyosis showed no significant association (184.17 ± 9.4 vs.184.66 ± 16.08, p = 0.86) from the topic endometrium of women without adenomyosis. Conclusion: TGF-ß1 expression was not increased in the ectopic endometrium of women with adenomyosis.

The graduated embryo score of embryos from infertile women with and without peritoneal endometriosis / Escore embrionário graduado em embriões de mulheres inférteis com e sem endometriose peritoneal

Abstract 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 (n= 109, infertile patients with tubal infertility) and 234 embryos from patients in the study group (n= 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. Themean GESwas performed to evaluate all embryos at 3 points in time: 16 to 18 hours, 25 to 27 hours, and 64 to 67 hours. Embryo evaluation was performed according to the following parameters: fragmentation, nucleolar alignment, polar body apposition, blastomere number/morphology, and symmetry. The primary outcomemeasure was the mean GES score.We also compared fertilization, implantation, and pregnancy rates. Results Although the number of embryos transferred was greater in patients with endometriosis than in the control group (2.38 ± 0.66 versus 2.15 ± 0.54; p= 0.001), the meanGESwas similar inbothgroups (71 ± 19.8 versus 71.9 ± 23.5; p= 0.881). Likewise, the fertilization ratewas similar in all groups, being 61% in patients with endometriosis and 59% in the control group (p= 0.511). No significant differences were observed in the implantation (21% versus 22%; [p= 0.989]) and pregnancy rates (26.4% versus 28.4%; p= 0.989). Conclusion Embryo quality measured by the mean GES was not influenced by peritoneal endometriosis. Likewise, the evaluated reproductive outcomes were similar between infertile patients with and without endometriosis.

Resumo Objetivo Determinar a qualidade do embrião (média de escore embrionário graduado [EEG]) em pacientes inférteis com endometriose submetidas à fertilização in vitro com transferência de embrião (FIV-TE) em comparação com pacientes inférteis sem endometriose. Métodos Realizamos um estudo de caso-controle comparando 706 embriões (162 pacientes) divididos em dois grupos: 472 embriões derivados de pacientes sem endometriose (n = 109, pacientes inférteis com infertilidade tubária) e 234 embriões de pacientes do grupo de estudo (n= 53, inférteis pacientes com endometriose peritoneal). Todos os pacientes foram submetidos à fertilização in vitro usando um protocolo follicle-stimulating hormone (FSH) recombinante de estradiol-antagonista para estimulação ovariana. A média do EEGfoi realizada para avaliar todos osembriõesemtrêsmomentos: de 16 a 18 horas, 25 a 27 horas e 64 a 67 horas.A avaliaçãoembrionária foi realizada de acordo comos seguintes parâmetros: fragmentação, alinhamento nucleolar, aposição do corpo polar, número de blastômeros/morfologia e simetria. A medida de desfecho primário foi o escore médios embrionário (EEG). Também avaliamos como desfechos secundários as taxas de fertilização, implantação e gravidez. Resultados Embora o número de embriões transferidos tenha sido maior em pacientes com endometriose do que no grupo controle (2,38 ± 0,66 versus 2,15 ± 0,54; p = 0,001), o EEGmédio foi semelhante nos dois grupos (71 ± 19,8 versus 71,9 ± 23,5; p = 0,881). Da mesma forma, a taxa de fertilização foi semelhante em todos os grupos, sendo 61% nos pacientes com endometriose e 59% no grupo controle (p = 0,511). Não foram observadas diferenças significativas nas taxas de implantação (21% versus 22%; [p = 0,989]) e nas taxas de gravidez (26,4% versus 28,4%; p = 0,989). Conclusão A qualidade embrionária medida pelo EEGmédio não foi influenciada pela endometriose peritoneal. Da mesma forma, os resultados reprodutivos avaliados foram semelhantes entre pacientes inférteis com e sem endometriose.

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). Inclusion criteria were patients with IVF indication and normal ovarian reserve. Embryo evaluation was performed on day three, after fertilization based on the Graduated Embryo Score (GES). RESULTS: There were no relevant differences in demographic characteristics. There was no difference in pregnancy rates with 27 (31%) and 25 (30.1%) pregnancies for rFSH and hMG, respectively (p=0.87). The total embryo score was the same for both groups, but the best embryo score was significant higher for the rFSH group (77.33±34.0 x 65.07±33.2 p=0.03). The total number of embryos was statistical different, also in favor of the rFSH group (4.17±3.1 x 3.26±2.4 p=0.04). CONCLUSION: The total embryo score was the same for both groups, but the best embryo score was significantly higher for the rFSH group. Moreover, rFSH was associated with an increased number of embryos.

Alterations in expression of endometrial milk fat globule-EGF factor 8 (MFG-E8) and leukemia inhibitory factor (LIF) in patients with infertility and endometriosis.

OBJECTIVE: The aim of this study was to compare the endometrial expression of milk fat globule-EGF factor 8 (MFG-E8), its receptor integrin αvß3, and leukemia inhibitory factor (LIF) in patients with endometriosis and infertility and in healthy fertile patients during the window of implantation. METHODS: Five patients with peritoneal endometriosis and infertility (case group) and four healthy fertile patients (control group) were recruited. All patients were either diagnosed with or ruled out for endometriosis by laparoscopic surgery; the case group underwent surgery for infertility investigation and the control group for tubal ligation. Endometrial biopsies were performed in all patients during the window of implantation (LH+8 to LH+10), and then the samples were analyzed by immunochemistry for MFG-E8, integrin αvß3, and LIF. RESULTS: In patients with endometriosis and infertility, expression of MFG-E8 was significantly increased in the glandular epithelium when compared to healthy fertile patients (p<0.001). Moreover, LIF expression was lower in patients with endometriosis and infertility (p<0.05). Nevertheless, we found no difference in integrin αvß3 expression between the groups (p=0.084). CONCLUSION: This study showed for the first time that MFG-E8 expression is impaired in the endometrium of patients with endometriosis and infertility during the window of implantation. Moreover, LIF is also diminished in the endometrium of these patients as shown before.

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. All patients had their endometriosis diagnosis made or excluded by laparoscopic surgery; study group was submitted to the surgery for infertility investigation and control group for tubal ligation. Day-3 serum hormones were collected from all patients. Analysis of nucleotide mutations for LH polymorphisms (Trp8Arg and Ile15Thr), LHR polymorphism (insLQ), and FSHR polymorphism (Asn680Ser) were performed by PCR. RESULTS: Day-3 FSH, estradiol and LH serum levels were not different between the groups, while CA-125 was higher in patients with endometriosis and infertility. All polymorphisms studied were in Hardy-Weinberg equilibrium. The prevalence of insLQ was significantly higher in patients with endometriosis and infertility (P = 0.005). Allele occurrence in control group was 0.10 versus 0.25 in infertile endometriosis group (P = 0.001). There was no difference regarding Trp8Arg/Ile15Thr (P > 0.05) and Asn680Ser (P > 0.05) prevalence between groups. CONCLUSION: This is the first time that prevalence of insLQ was shown to be higher in patients with endometriosis and infertility than in healthy fertile patients. There was no difference in LH and FSHR polymorphisms' prevalence between groups.

Frequent polymorphisms of FSH receptor do not influence antral follicle responsiveness to follicle-stimulating hormone administration as assessed by the Follicular Output RaTe (FORT).

PURPOSE: To verify whether carriers of common single-nucleotide polymorphisms (SNPs) of the FSH receptor (FSHR) show reduced responsiveness of antral follicles to FSH administration as assessed by the FORT. METHODS: We performed a prospective study in a university hospital. Study population consisted of 124 Caucasian IVF-ET candidates. FSHR 307Ala and 680Ser variants were analyzed in haplotypes and as separated genes. Serum FSH, estradiol (E(2)), and anti-Müllerian hormone (AMH) were measured on cycle-day 3. Antral follicle (3-8 mm) count (AFC) and preovulatory follicle (16-22 mm) count (PFC) were performed, respectively, at the achievement of pituitary suppression (before FSH administration) and on the day of hCG administration. Antral follicle responsiveness to FSH administration assessed by the FORT (PFCx100/AFC). RESULTS: Data concerning baseline and IVF-ET parameters were similar between SNPs carriers and controls. Moreover, FORT was similar for different haplotypes Thr307-Asn680 (45.9%) and Ala307-Ser680 (39.4%) and 307Thr/Ala-Ala/Ala (41.1%; 5.0-91.6%) versus 307Thr/Thr (44.4%; 17.3-83.3%) and in 680Asn/Ser-Ser/Ser (40.0%; 5.0-91.6%) versus 680Asn/Asn (42.2%; 8.3-90.0%) carriers. CONCLUSIONS: Antral follicle responsiveness to FSH, as far as measured by the FORT, is not influenced by the presence of SNPs of FSHR 307Ala and 680Ser.

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). They underwent an outpatient diagnostic hysteroscopy study, with either congenital or acquired abnormalities of the uterine cavity being identified. RESULTS: Uterine changes were found in 22 (33.3%) patients, with 9 cases of congenital changes [arcuate uterus (4 cases), septate uterus (2 cases), and bicornuate uterus (1 case)], and 13 patients with acquired changes [intrauterine adhesions (7 cases), endometrial polyp (4 cases), and uterine leiomyoma (2 cases)]. No significant differences were found between the groups as regarding both acquired and congenital uterine changes. A positive correlation was found between anatomical changes on hysteroscopy and number of miscarriages (r = 0.31; p = 0.02). CONCLUSION: Patients with more than two miscarriages have a high prevalence of uterine cavity abnormalities diagnosed by hysteroscopy; however there are no differences in prevalence or distribution of these lesions related to the number of recurrent miscarriages.

Histeroscopia ambulatorial em casos de abortamento consecutivo / Office hysteroscopy study in consecutive miscarriage patients

OBJETIVO: Avaliar a prevalência de alterações anatômicas uterinas diagnosticadas através da histeroscopia ambulatorial em uma população de pacientes com mais de dois abortamentos consecutivos. Comparar a prevalência de alterações uterinas entre as pacientes com dois abortos em relação as pacientes com três ou mais abortamentos de repetição. MÉTODOS: Foi realizado um estudo transversal em 66 pacientes com diagnóstico de dois ou mais abortamentos de repetição. As pacientes foram divididas em dois grupos: Grupo A (até dois abortamentos, 23 pacientes) e Grupo B (três ou mais abortamentos, 43 pacientes), sendo submetidas à histeroscopia diagnóstica ambulatorial em que foram identificadas alterações congênitas e adquiridas da cavidade uterina. RESULTADOS: Foram encontradas em 22 (33,3 por cento) pacientes alterações uterinas, sendo em nove casos alterações congênitas [útero arqueado (quatro casos), septo uterino (dois casos) e útero bicorno (um caso)] e em 13 pacientes alterações adquiridas [sinéquia (sete casos), pólipo endometrial (quatro casos) e mioma uterino (dois casos). Não houve diferença significativa entre grupos em relação às alterações uterinas adquiridas e congênitas. Foi encontrada uma correlação positiva entre alterações anatômicas na histeroscopia e número de abortamentos (r = 0,31; p = 0,02). CONCLUSÃO: As pacientes com mais de dois abortamentos apresentam uma alta prevalência de alterações uterinas diagnosticadas por histeroscopia. No entanto não há diferença na prevalência ou na distribuição das lesões em relação ao número de abortamentos.

T helper (Th)1, Th2, and Th17 interleukin pathways in infertile patients with minimal/mild endometriosis.

In the present study, interleukin (IL)-10, IL-12, IL-17, and IL-23 levels were measured in serum and peritoneal fluid of women with minimal or mild endometriosis and compared with levels in controls without endometriosis. Higher IL-23 levels were encountered in the peritoneal fluid of women with endometriosis, suggesting a possible role of this cytokine in these women's infertility.

References to alcohol consumption and alcoholism in medical records of a general hospital of Porto Alegre, Brazil--a comparison between samples with a 20 year gap.

Two samples of inpatients (493 and 158 subjects, respectively) of a large teaching hospital, collected using the same methodology and with a 20-year time frame, were analyzed aiming at finding information about alcohol consumption, abuse or dependence in the subjects' medical charts. Items reviewed were: the list of medical problems; hospital intake form; daily nursing review; medical anamnesis; pre-surgery records, and discharge forms. Only 54% and 50% of each sample, respectively, had some type of reference to alcohol consumption; when references were present, they were in most part incomplete, possibly reflecting distortions in the process of gathering information about alcohol consumption that involves the client and the health professionals. The authors discuss potential reasons for this, suggesting that lack of training of medical personnel in the identification of alcoholism, as well as prejudice towards its recovery, may be some of the underlying causes.
