Anti-müllerian hormone is the best predictor of poor response in ICSI cycles of patients with endometriosis.

PURPOSE: To correlate ovarian reserve (OR) markers with response in assisted reproduction techniques (ART) and determine their ability to predict poor response among patients with endometriosis (EDT). METHODS: We evaluated ART cycles of 27 women with EDT and 50 with exclusive male factor. Basal follicle stimulating hormone (FSH) and anti-müllerian hormone (AMH) levels were determined. Ovarian response to gonadotropin stimulation was assessed and correlation coefficients calculated between the variables and reserve markers. Areas under the curve (AUC) determined ability of tests to predict poor response. RESULTS: AMH was significantly correlated with response in both groups and it was the only marker with significant discriminative capacity to predict poor response among EDT (AUC = 0.842; 95% CI: 0.651-0.952) and control group (AUC = 0.869; 95% CI: 0.743-0.947). CONCLUSION: Infertile patients with endometriosis can benefit from the pre-therapeutic assessment of OR markers. However, regardless of disease presence, only AMH predicts poor response to stimulus.

Serological testing for celiac disease in women with endometriosis. A pilot study.

PURPOSE OF INVESTIGATION: Celiac disease (CD) involves immunologically mediated intestinal damage with consequent micronutrient malabsorption and varied clinical manifestations, and there is a controversial association with infertility. The objective of the present study was to determine the presence of CD in a population of infertile women with endometriosis. METHODS: A total of 120 women with a diagnosis of endometriosis confirmed by laparoscopy (study group) and 1,500 healthy female donors aged 18 to 45 years were tested for CD by the determination of IgA-transglutaminase antibody against human tissue transglutaminase (t-TGA) and anti-endomysium (anti-EMA) antibodies. RESULTS: Nine of the 120 women in the study group were anti-tTGA positive and five of them were also anti-EMA positive. Four of these five patients were submitted to intestinal biopsy which revealed CD in three cases (2.5% prevalence). The overall CD prevalence among the population control group was 1:136 women (0.66%). CONCLUSION: This is the first study reporting the prevalence of CD among women with endometriosis, showing that CD is common in this population group (2.5%) and may be clinically relevant.

Metabolic and cardiovascular impact of oral contraceptives in polycystic ovary syndrome.

Chronic anovulation, polycystic ovarian morphology and hyperandrogenism are the diagnostic criteria for polycystic ovary syndrome (PCOS). Metabolic disturbances are more common in PCOS women who are prone to develop metabolic syndrome and to present higher levels of some cardiovascular disease risk marker. Oral contraceptives are widely used in PCOS, but conflicting data have been reported regarding their impact on carbohydrate and lipid metabolism on PCOS women. This paper presents a critical evaluation of combined oral contraceptives (COCs) metabolic effect - carbohydrate metabolism and insulin sensitivity, lipid metabolism, haemostasis, body weight, arterial pressure and cardiovascular impact - on PCOS women. Because of the paucity of data on the impact of COCs on cardiovascular and metabolic parameters in PCOS patients, most of there commendations are based on studies involving ovulatory women. The use of low-dose COCs is preferable in PCOS, especially among patients with glucose intolerance, insulin resistance and uncomplicated diabetes mellitus. Although reported as a side effect of COCs, marked weight gain has not been confirmed among users. However, when arterial hypertension or elevated risk for thromboembolism is present, progestogen-only hormonal contraceptives should be used instead of COCs. Regarding dyslipidaemia, COCs reduce low-density lipoprotein and total cholesterol and elevate high-density lipoprotein and triglycerides, and therefore are not recommended for women with high triglycerides levels. The choice of a COC, which alleviates the PCOS-induced hyperandrogenism without significant negative impact on cardiovascular risk, is one of the greatest challenges faced by gynaecologists nowadays.

Reliability and validity of tissue volume measurement by three-dimensional ultrasound: an experimental model.

OBJECTIVE: To determine the validity and the intra- and interobserver reliability of volume measurements of an endometrium-like model using a three-dimensional (3D) ultrasound rotational technique. METHODS: A 3D ultrasound dataset was obtained from a sample of bovine liver containing a portion of chicken chest muscle (CCM). The process was repeated seven times using pieces of CCM of different sizes, resulting in seven datasets. Each portion of CCM was then placed in a water-filled volume-scaled tube and the 'actual' volumes were calculated by water displacement. For each dataset, ten volumes were calculated by each of two observers using a (VOCAL) with a 15 degrees rotational step. Reliability was assessed by calculating intraclass correlation coefficients (ICC) and validity by examining the percentage difference from the actual volume using limits of agreement. RESULTS: The volume measurement of organic tissues using the 3D ultrasound rotational method was highly reliable (intraobserver ICC, 0.998 for Observer 1 and 0.997 for Observer 2; interobserver ICC, 0.997) and valid (the bias and 95% limits of agreement of the percentage difference from the actual volume was only 0.57 (-3.07 to 4.21) % for Observer 1 and - 0.17 (-4.34 to 4.0) % for Observer 2). CONCLUSIONS: The 3D sonographic measurement, using VOCAL with a 15 degrees rotational step, of small and irregular tissues is reliable and valid, suggesting that it is a useful technique for measurement of the endometrial volume and other volumes of similar size.

Effect of metformin on the clinical and metabolic assessment of women with polycystic ovary syndrome.

A longitudinal prospective study was conducted in 21 women with polycistic ovary syndrome (PCOS), aged 27.20 +/- 5.02 years and treated with metformin (1500 mg/day)for 8 weeks. The patients were assessed for spontaneous menstruation, weight, body mass index (BMI), waist circumference, waist/hip ratio (WHR), glucose and insulin concentrations under fasting conditions and after a 75-g glucose tolerance test, lipid profile, testosterone, androstenedione, dehydroepiandrosterone sulfate, sex-hormone binding globulin (SHBG), and insulin-like growth factor (IGF)-I. Spontaneous menstruation was observed in 81% of the women treated with metformin, with no changes in weight or BMI. Waist measurement and the WHR were reduced. The quantitative insulin sensitivity check index (QUICKI) improved from 0.33 +/- 0.03 to 0.35 +/- 0.04 (p < 0.005), and serum total cholesterol and low-density lipoprotein-cholesterol were reduced, while high-density lipoprotein-cholesterol was increased. Serum testosterone concentrations were also reduced. There were no differences in serum triglycerides, SHBG or IGF-I. The occurrence of spontaneous menstruation and changes in the pattern of body fat distribution, the reduction in serum testosterone concentrations, the improvement in lipid profile and the reduction of insulinemia with the use of metformin permit us to conclude that treatment with this drug is of benefit to women with PCOS.

Effect of inseminated volume on intrauterine insemination.

PURPOSE: Intrauterine insemination (IUI) is a method for the treatment of marital infertility involving the intrauterine or fallopian deposition of washed spermatozoa, depending on the amount of inseminated semen. In view of the divergent opinions about the inseminated volume, the objective of this study was to compare the two techniques (3.0 mL or 0.5 mL) in two groups of patients. METHODS: We performed 164 cycles of ovulation induction followed by IUI. The patients were divided into two groups according to the technique used. Group low volume--50 cycles and 0.5 mL of inseminated semen; Group high volume--114 cycles and 3.0 mL of inseminated semen. The cycle was monitored on the basis of endometrial thickness and follicular development measured by transvaginal ultrasound. Human chorionic gonadotrophin (hCG) was administered in the presence of a follicle measuring 18 mm in mean diameter. The procedure was performed after sperm washing using a discontinuous PureSperm gradient, 40 h later. RESULTS: We obtained a similar clinical pregnancy rate for the two groups (14.0% for Group low volume and 15.7% for Group high volume). There was one abortion in each group. We detected no interference by any etiology of infertility or by the total motile recovered sperm with pregnancy rate. CONCLUSIONS: The results did not demonstrate superiority of one method over the other, with both therapeutic alternatives being satisfactory for the treatment of infertile couples.

Familial risk among patients with endometriosis.

PURPOSE: The objective of the present study was to determine the prevalence of endometriosis among the relatives of patients with confirmed endometriosis. METHODS: We analyzed the prevalence of endometriosis among first-, second-, and third-degree relatives in a group of 101 patients with varying symptoms related to endometriosis seen at two public hospitals and submitted to laparoscopy and/or laparotomy. The control group consisted of 43 women submitted to laparoscopy without a diagnosis of endometriosis. RESULTS: Among the patients with endometriosis, we detected nine families with a positive history of endometriosis, comprising one mother, six sisters, three aunts, and two cousins, as opposed to no case among the controls. CONCLUSIONS: These data confirm a familial tendency for endometriosis and suggest that this disorder has a genetic basis.

Insulin secretion in obese and non-obese women with polycystic ovary syndrome and its relationship with hyperandrogenism.

Insulin resistance has been reported to be associated with hyperandrogenism and polycystic ovaries. To study the prevalence of insulin resistance in patients with polycystic ovary syndrome (PCO) and the correlation between hyperinsulinemia and hyperandrogenism, 48 patients were divided into four groups: group 1, non-obese ovulatory women (n = 10); group 2, obese ovulatory women (n = 9); group 3, non-obese women with PCO (n = 14); group 4, obese women with PCO (n = 15). Each patient was submitted to an oral glucose tolerance test (OGTT). Glucose, insulin, androstenedione and testosterone levels were determined and the blood glucose and insulin response of women with PCO and normal women were compared. Glucose intolerance was observed in group 3 (28.6%) and group 4 (40%) but not in groups 1 or 2, and hyperinsulinemia was observed in group 2 (66.7%), group 3 (64.3%) and group 4 (86.6%). There was a correlation between androstenedione and testosterone levels and insulinemia in group 4. There was also a high prevalence of insulin resistance in patients with PCO regardless of obesity, and hyperandrogenism-aggravated insulin resistance.

[AIDS and HIV infection among homosexual and bisexual men in Belém, Pará, Brazil, 1988-1990]. / SIDA e infecção pelo HIV em homossexuais e bissexuais masculinos em Belém, Pará, Brasil, 1988-1990.

During three years (1988-1990) blood samples from 307 people were taken to test antibodies for Human Immunodeficiency Virus type 1 (HIV-1) in homo and bisexual males living in Belém, being 149 (48.5%) of the former and 158 (51.5%) of the later. All patients requested examinations spontaneously to find out their status. The ages of tested people ranged from 16 to 64 years old. Serologic diagnosis was made using an enzyme immunoassay (Abbott, São Paulo-Brasil) for screening and an indirect immunofluorescence test (FIOCRUZ, Rio de Janeiro-Brasil) for confirmation. If results were conflicting with these tests, western blot (Du Pont CO. Wilmington-USA) was performed to obtain a definitive result. Sixty-eight (22.1%) of all sera were positive. Although, the positivity in the homosexual group (26.2%) was more higher than in the bisexual group (18.3%). The positivity rate in both groups was directly proportional with the increase of age. Of course, people with less than 20 years old had only 3% of positivity, while between 20-29 had 18.1%, 30-39 had 34.5%, 40-49 had 40% and 50-59 had 50%. The projected curve of positivity, is progressive, that is to say, the risk of homo/bisexual males increases with age and is probably related to increased sexual activity. We conclude that more than one quarter of homosexual men are infected with HIV-1 in Belém.
