Views83PURPOSE: to evaluate the frequency of VDR gene polymorphism Fok1 in infertile women with endometriosis and Control and its relation to the disease. METHODS: a case-control study that included 147 infertile women with endometriosis and 154 fertile women without endometriosis as Control. Fok1 polymorphism (rs10735810, T2C), which promotes a T/C exchange in exon 2 of the VDR gene, was identified by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), that involves the combination of amplification by PCR and digestion with restriction endonuclease. The χ2 test was used to compare allele and genotype frequencies between groups. All p-values were two-tailed and a p-value < 0.05 was considered statistically significant. RESULTS: the TT, TC and CC genotype frequencies of VDR Fok1 polymorphism were 44.2%, 46.9% and 8.9% in infertile women with endometriosis and 41.6%, 50% and 8.4% in the Control Group. No significant difference was found (p=0.8), even when the patients were subdivided according to the stage of endometriosis (p=0.3 for minimal and mild endometriosis and p=0.2 for moderate and severe endometriosis). Alleles T and C were present, respectively, in 67.6% and 32.3% of infertile women with endometriosis (p=0.8), in 63.5% and 36.5% of women with minimal/mild endometriosis (p=0.5), in 72.5% and 27.5% of women with moderate/severe endometriosis (p=0.2), and in 66.6% and 33.4% of the Control Group. No statistically significant difference was found among any groups and the Control. CONCLUSION: the results suggest that VDR gene polymorphism Fok1 does not confer genetic susceptibility to endometriosis-associated infertility in the Brazilian population.

Views92See morePURPOSE: to evaluate the frequency of TP53 codon 72 polymorphism in infertile women with endometriosis, women with idiopathic infertility, controls and its relation to the disease. METHODS: a case-control study that included 198 infertile women with endometriosis, 70 women with idiopathic infertility and 169 fertile women without endometriosis as control. Detection of TP53 codon 72 gene polymorphism (rs1042522, Arg/C:Pro/G), that promotes a C/G exchange in the coding region of the gene, was performed by real time Polymerase Chain Reaction (PCR), using the TaqMan system of primers, that flank the implicated region and probes labeled with different fluorescent dyes, one for allele C and other for allele G. When two dyes were observed, the patient was considered to be heterozygous CG. In the presence of only one dye, the individual was considered to be homozygous CC or GG. The χ2 test was used to compare allele and genotype frequencies between groups. All p-values were two-tailed and a p-value <0.05 was considered to be statistically significant. RESULTS: we found no statistically significant difference in the distribution of TP53 codon 72 polymorphism genotypes CC, CG or GG (p=0.7) and alleles C or G (p=0.4) between infertile patients with endometriosis and controls (p=0.4), regardless of the stage of the disease. In relation to infertility, no statistically significant difference in the genotype or allele distribution (p=1.0 and p=0.9, respectively) was observed between idiopathic infertile women and controls. Considering the dominant inheritance model, again, no statistically significant difference was found even in the endometriosis (p=0.5) or the idiopathic infertility group (p=0.9) when compared to controls. Regarding the recessive inheritance model no statistically significant difference was found, with p=0.6 and p=1.0, respectively, for the endometriosis and idiopathic infertility groups. CONCLUSION: the results suggest that the TP53 codon 72 polymorphism does not confer genetic susceptibility to endometriosis and/or infertility in the Brazilian population, not even the severe form of the disease.

Views67See moreEndometriosis is characterized by the presence of endometrial tissue, localized outside the uterine cavity, such as peritoneal surface, ovaries, and rectum-vaginal septum. The prevalence is about 6 to 10%. Concerning the etiopathogenesis, the retrograde menstruation theory is accepted, although disruption in endometrial molecular biology seems to be fundamental to the development of endometriosis ectopic focuses. Women with endometriosis may be asymptomatic or may present complaints of dysmenorrhea, dispareunia, chronic pelvic pain and/or infertility. Although the definitive diagnosis of endometriosis needs a surgical intervention, mainly by laparoscopy, many findings obtained by physicalexamination and imaging and laboratory tests can predict, with a high degree of reliability, that the patient has endometriosis. The most common current treatments include surgery, ovarian suppression therapy or both. Pharmacological treatments that do not inhibit ovarian function are under investigation.

Views47See morePURPOSE: to compare serum markers of oxidative stress between infertile patients with and without endometriosis and to assess the association of these markers with disease staging. METHODS: this was a prospective study conducted on 112 consecutive infertile, non-obese patients younger than 39 years, divided into two groups: Endometriosis (n=48, 26 with minimal and mild endometriosis - Stage I/II, and 22 with moderate and severe endometriosis - Stage III/IV) and Control (n=64, with tubal and/or male factor infertility). Blood samples were collected during the early follicular phase of the menstrual cycle for the analysis of serum malondialdehyde, glutathione and total hydroxyperoxide levels by spectrophotometry and of vitamin E by high performance liquid chromatography. The results were compared between the endometriosis and control groups, stage I/II endometriosis and control, stage III/IV endometriosis and control, and between the two endometriosis subgroups. The level of significance was set at 5% (p<0.05) in all analyses. RESULTS: vitamin E and glutathione levels were lower in the serum of infertile women with moderate/severe endometriosis (21.7±6.0 mMol/L and 159.6±77.2 nMol/g protein, respectively) compared to women with minimal and mild endometriosis (28.3±14.4 mMol/L and 199.6±56.1 nMol/g protein, respectively). Total hydroxyperoxide levels were significantly higher in the endometriosis group (8.9±1.8 µMol/g protein) than in the Control Group (8.0±2 µMol/g protein) and among patients with stage III/IV disease (9.7±2.3 µMol/g protein) compared to patients with stage I/II disease (8.2±1.0 µMol/g protein). No significant differences in serum malondialdehyde levels were observed between groups. CONCLUSIONS: we demonstrated a positive association between infertility related to endometriosis, advanced disease stage and increased serum hydroxyperoxide levels, suggesting an increased production of reactive species in women with endometriosis. These data, taken together with the reduction of serum vitamin E and glutathione levels, suggest the occurrence of systemic oxidative stress in women with infertility associated with endometriosis. The reproductive and metabolic implications of oxidative stress should be assessed in future studies.

Views80See morePURPOSE: to evaluate the ovarian reserve of infertile patients with severe ovarian endrometriosis, submitted to excisional surgery of endometriomas and attended from February to November, 2008. METHODS: prospective study, including 30 patients with endometriosis grades III and IV, with severe ovarian impairment, submitted to excisional surgery of the endometriomas, and 30 patients with endometriosis grades I and II, allocated as a Control Group. The ovarian reserve was indirectly assessed, through the basal (U/L) follicle stimulating hormone (FSH), between the third and fifth days of the cycle, 12 months after the surgery. The body mass index (BMI) was calculated according to Quetelet's formula [weight (kg)/height(cm²)]. The Mann-Whitney non-parametric U test was used to compare the variables "age", "BMI" and "basal SFH" between the groups. RESULTS: there was no significant difference between the groups about age and BMI. Concerning basal FSH, in the group of patients with severe endometriosis, the average value was 7.0 U/L, while in the Control Group, it was 5.6 U/L (p=0.3), what demonstrates that the difference between the two groups was not significant. CONCLUSIONS: the surgery did not affect the ovarian reserve of patients with severe ovarian endometriosis.

Views42See morePURPOSE: the objective of the present study was the development of the Brazilian Portuguese version of Endometriosis Health Profile Questionnaire (EHP-30), the cross-cultural adaptation to Brazil and the evaluation of EHP-30 Portuguese psychometric measures in a Brazilian sample. METHODS: the original instrument in English was translated into Portuguese following international guidelines, going through all stages of translation, back-translation and comparison of the versions for cross-cultural adaptation, face and content validity. A sample of 54 patients with endometriosis was used for internal consistency analyses using the Cronbach alpha. Test-retest reliability was evaluated through the intraclass correlation coefficient (ICC). In order to evaluate the convergent construct validity, the correlation between EHP-30 Portuguese and WHOQOL-Bref and Beck Depression Inventory (BDI) was tested. RESULTS: internal consistency presented alpha values of 0.8 to 0.9 suggesting homogeneity between questions. The test-retest reliability presented ICC of 0.8 to 0.9 showing instrument stability. In the construct validation, strong correlations were demonstrated of the EHP-30 Portuguese self-image scale with physical (-0.6) and psychological domains (-0.6) of WHOQOL-Bref, and EHP-30 Portuguese social support scale with BDI (0.5), confirming good correlation with other quality of life evaluation instruments. CONCLUSIONS: the EHP-30 Portuguese was found to be an easy, quickly applied instrument, and well-accepted by the patients. It presented good psychometric properties with appropriate reliability measures (internal consistency and test-retest reliability) and construct validity. These results show that EHP-30 Portuguese is an adequate instrument for quality of life evaluation in Brazilian women with endometriosis, both in clinical and research setting.

Views98See morePURPOSE: to evaluate the sensitivity, specificity, positive and negative predictive value of double contrast barium enema (DCBE) for the diagnoses of rectum and sigmoid endometriosis. METHODS: prospective transversal study including 37 patients with suspicion of deep endometriosis. Patients were submitted to DCBE, according to the standard technique described in the literature, and then, to laparoscopy. The results of laparoscopy and the DCBE images were interpreted and compared, based on the histological evaluation. Statistical analysis was done by association (χ2 test) and agreement analyses (Kappa's test). RESULTS: patients' average age was 35.8±4.4 years old (age group from 28 to 48 years), 85.6% of them being white and 14.4%, black women. Deep endometriosis was confirmed by laparoscopy and histological exam in all the studied patients. Intestinal endometriosis was confirmed by histological exam in 27 women (72.9%) of them. DCBE demonstrated suggestive radiologic signs of intestinal infiltration by endometriosis in 24 women (64.9%) and no signs in 13 women (35.1%). The method sensitivity was 67.5%, specificity 53.8%, positive predictive value, 77.8% and negative predictive value, 70%. Among the 24 abnormal exams, 16 (43.2%) presented radiologic speculum-type image, 16 (43.2%), an image compatible with stenosis, and four (10.8%), double contour. CONCLUSIONS: the DCBE presents high sensitivity and high positive predictive value, in the diagnosis of the rectum and sigmoid endometriosis. Radiologic images speculum and stenosis-type present high sensitivity and positive predictive value for the intestinal infiltration by endometriosis.

Views110See morePURPOSE: to evaluate the meiotic spindle and the chromosome distribution of in vitro mature oocytes from stimulated cycles of infertile women with endometriosis, and with male and/or tubal infertility factors (Control Group), comparing the rates of in vitro maturation (IVM) between the two groups evaluated. METHODS: fourteen patients with endometriosis and eight with male and/or tubal infertility factors, submitted to ovarian stimulation for intracytoplasmatic sperm injection have been prospectively and consecutively selected, and formed a Study and Control Group, respectively. Immature oocytes (46 and 22, respectively, from the Endometriosis and Control Groups) were submitted to IVM. Oocytes presenting extrusion of the first polar corpuscle were fixed and stained for microtubules and chromatin evaluation through immunofluorescence technique. Statistical analysis has been done by the Fisher's exact test, with statistical significance at p<0.05. RESULTS: there was no significant difference in the IVM rates between the two groups evaluated (45.6 and 54.5% for the Endometriosis and Control Groups, respectively). The chromosome and meiotic spindle organization was observed in 18 and 11 oocytes from the Endometriosis and Control Groups, respectively. In the Endometriosis Group, eight oocytes (44.4%) presented themselves as normal metaphase II (MII), three (16.7%) as abnormal MII, five (27.8%) were in telophase stage I and two (11.1%) underwent parthenogenetic activation. In the Control Group, five oocytes (45.4%) presented themselves as normal MII, three (27.3%) as abnormal MII, one (9.1%) was in telophase stage I and two (18.2%) underwent parthenogenetic activation. There was no significant difference in meiotic anomaly rate between the oocytes in MII from both groups. CONCLUSIONS: the present study data did not show significant differences in the IVM or in the meiotic anomalies rate between the IVM oocytes from stimulated cycles of patients with endometriosis, as compared with controls. Nevertheless, they have suggested a delay in the outcome of oocyte meiosis I from patients with endometriosis, shown by the higher proportion of oocytes in telophase I observed in this group.
