RESUMO

Objective: In autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) defects in the autoimmune regulator gene lead to impaired immunotolerance. We explored the effects of immunodeficiency and endocrinopathies on gynecologic health in patients with APECED. Design: Cross-sectional cohort study combined with longitudinal follow-up data. Methods: We carried out a gynecologic evaluation, pelvic ultrasound, and laboratory and microbiologic assessment in 19 women with APECED. Retrospective data were collected from previous study visits and hospital records. Results: The study subjects' median age was 42.6 years (range, 16.7-65.5). Sixteen patients (84%) had premature ovarian insufficiency, diagnosed at the median age of 16.5 years; 75% of them used currently either combined contraception or hormonal replacement therapy. In 76% of women, the morphology and size of the uterus were determined normal for age, menopausal status, and current hormonal therapy. Fifteen patients (79%) had primary adrenal insufficiency; three of them used dehydroepiandrosterone substitution. All androgen concentrations were under the detection limit in 11 patients (58%). Genital infections were detected in nine patients (47%); most of them were asymptomatic. Gynecologic C. albicans infection was detected in four patients (21%); one of the strains was resistant to azoles. Five patients (26%) had human papillomavirus infection, three of which were high-risk subtypes. Cervical cell atypia was detected in one patient. No correlation between genital infections and anti-cytokine autoantibodies was found. Conclusions: Ovarian and adrenal insufficiencies manifested with very low androgen levels in over half of the patients. Asymptomatic genital infections, but not cervical cell atypia, were common in female patients with APECED.

RESUMO

Although carbohydrate antigen 19-9 (CA 19-9) may be elevated in benign diseases, elevated CA 19-9 may cause a fear of cancer and unnecessary follow-up studies. Research on how to approach systematically in this case is very limited. The purpose of this study was to analyze the clinical features and the causes of CA 19-9 elevation without evidence of malignant or pancreatobiliary diseases. We retrospectively reviewed the medical records of patients who had CA 19-9 elevation (≥80 U/mL) and were found to be unrelated to cancer after follow-up. After exclusion, 192 patients were included in this study. The median level of CA 19-9 was 136.5 U/mL. The causes of CA 19-9 elevation were determined in 147 (76.6%) patients, and that was unknown in 45 (23.4%). The estimated causative diseases were hepatic diseases in 63 patients, pulmonary diseases in 32, gynecologic diseases in 38, endocrine diseases in 13, and spleen disease in 1. Of 45 patients with unknown cause, 35 had normalization of CA 19-9 and 10 had persistently elevated CA 19-9. In conclusion, CA 19-9 elevation without malignancies or pancreatobiliary diseases should be systematically evaluated and followed up. We suggest an algorithm to investigate the causes and follow up these patients.

RESUMO

BACKGROUND/AIM: Many studies have shown an antiproliferative, anti-inflammatory, anti-angiogenetic, and apoptosis-inducing effect of Vitamin D. A vitamin D deficiency has been associated with an increased risk for different types of cancer. This study examined vitamin D 25(OH)D levels in gynaecological cancers in comparison with benign gynaecological diseases. PATIENTS AND METHODS: Serum 25(OH)D levels in 688 gynaecological patients (488 with malignant, 200 with a benign gynaecological disease) were assayed between 2009 and 2015 using an electrochemiluminescence immunoassay. RESULTS: In total, the 25(OH)D levels in cancer patients were lower, but not significantly lower than those in cancer-free patients. Significant results were shown regarding seasonal effects for patients with breast-, endometrial and ovarian cancer. No significant effects occurred with regard to menopause status, nicotine, or grade in relation to 25(OH)D levels. CONCLUSION: 25(OH)D levels seem to influence gynaecological cancers.

RESUMO

Iron deficiency anemia (IDA) is a common micronutrient deficiency worldwide, and an important health problem especially in women of reproductive age. This study aimed to determine the relationship between IDA and sexual satisfaction and function among reproductive-aged Iranian women. In this study, 129 women (52 with IDA and 77 non-IDA) with age 18-45 in Mahshahr, Iran were recruited. Data was gathered by a demographic questionnaire, Female Sexual Function Index (FSFI) and Larson Sexual Satisfaction Questionnaire. Data were analyzed using an independent t-test, Mann-Whitney test, Chi-square, and correlation coefficient test. The results of this study showed that the means of hemoglobin (Hb), hematocrit (HCT), serum iron and ferritin were significantly lower in the IDA group than those in the non-IDA group (p<0.01). All dimensions of sexual function and satisfaction were significantly lower in women with IDA compared to the healthy women (p<0.001). Also, all blood indices for IDA had a significant relationship with all sexual function components and sexual satisfaction (p = 0.01) except for pain with Hb and ferritin. Health care providers should provide screening, education, and counseling about anemia and sexual function in reproductive age women.

RESUMO

BACKGROUND: There is currently no reliable serum biomarker for ovarian clear cell carcinoma (CCC), a highly lethal histological subtype of epithelial ovarian cancer (EOC). Previously, using a proteome-based approach, we identified tissue factor pathway inhibitor 2 (TFPI2) as a candidate serum biomarker for CCC. In this study, we sought to evaluate the clinical diagnostic performance of TFPI2 in preoperative prediction of CCC. METHODS: Serum TFPI2 levels were measured in serum samples from a retrospective training set consisting of patients with benign and borderline ovarian tumors, EOC subtypes, and uterine diseases. Via receiver operating characteristic (ROC) analyses, we compared the diagnostic performance of TFPI2 with that of CA125 in discrimination of patients with ovarian CCC from other patient groups. The observed diagnostic performances were examined in a prospective validation set. RESULTS: The 268-patient training set included 29 patients with ovarian CCC. Unlike CA125, which was also elevated in patients with endometriosis and several EOC subtypes, serum TFPI2 levels were specifically elevated only in ovarian CCC patients, consistent with the mRNA expression pattern in tumor tissues. The area under the ROC curve (AUC) of serum TFPI2 was obviously higher than that of CA125 for discrimination of CCC from other ovarian diseases (AUC = 0.891 versus 0.595). Applying a cut-off value of 280 pg/mL, TFPI2 could distinguish early-stage (FIGO I and II) CCC from endometriosis with 72.2% sensitivity, 93.3% specificity, and 88.8% accuracy. Similar results were confirmed in an independent 156-patient prospective validation set. CONCLUSIONS: TFPI2 is a useful serum biomarker for preoperative clinical diagnosis of CCC.

RESUMO

BACKGROUND: This study investigated the clinical value of HE4 in distinguishing malignant and benign gynecological diseases of patients in southern China. METHODS: Preoperative serum CA125 and HE4 concentrations were tested in samples of women with malignant or benign gynecological diseases using fully automated methods (Abbott ARCHITECT) and validated cutoff values. RESULTS: For the discrimination of ovarian cancer from benign gynecological diseases, in premenopausal women, the sensitivity and specificity were 89.8% and 67.5% for CA125, 68.5% and 97.8% for HE4, and 88.9% and 78.6% for ROMA, whereas in postmenopausal women, the sensitivity and specificity were 86.6% and 88.9% for CA125, 57.3% and 100% for HE4, and 85.4% and 94.4% for ROMA. For the discrimination of endometrial cancer from benign gynecological diseases, in premenopausal women, the sensitivity and specificity were 20.3% and 67.5% for CA125, 56.8% and 97.8% for HE4, and 74.3% and 78.6% for ROMA, whereas in postmenopausal women, the sensitivity and specificity were 17.8% and 88.9% for CA125, 31.5% and 100% for HE4, and 32.9% and 94.4% for ROMA. CONCLUSIONS: We showed that HE4 had better specificity than CA125 in discriminating ovarian cancer, and endometrial cancer from benign gynecological diseases in southern China population.

RESUMO

Cancer of the reproductive tract is an important cause of morbidity and mortality among women worldwide. In this study we evaluated the influence of diagnostic categories, age and reproductive factors on antioxidant enzymes and lipid hydroperoxides in the blood of gynaecological patients diagnosed with endometrial polyp, myoma, hyperplasia simplex, hyperplasia complex and endometrial adenocarcinoma. Multivariate regression analysis was used to assess the association of diagnosis, age, parity, abortions and abnormal uterine bleeding with the examined parameters. Diagnosis provided the best predictive model for superoxide dismutase, catalase and glutathione peroxidase activities, and also for the lipid hydroperoxide level. Abortions fitted the best predictive model for superoxide dismutase activity. A significant correlation was also found between the predictor variables themselves. This study showed that reproductive and other factors may be associated, at least partially, with antioxidant capacity and ability to defend against the oxidative damage in gynaecological patients with various diagnoses.

RESUMO

We examined the serum concentration of human epididymis protein (HE4) in patients with benign gynecological diseases complicated with chronic renal deficiency and its significance in the differential diagnosis of benign and malignant gynecological diseases. Serum HE4 and cancer antigen 125 concentrations were detected by chemiluminescence. Clinically or pathologically confirmed gynecological diseases were grouped and retrospectively analyzed, including 50 cases of gynecological benign diseases, 35 cases of non-mucinous epithelial ovarian carcinoma, 36 cases of endometrial adenocarcinoma, 15 cases of gynecological benign diseases patients complicated with chronic renal deficiency, 15 cases of gynecological diseases without chronic renal deficiency, and 30 normal controls. Serum HE4 values in the ovarian cancer group, endometrial cancer group, gynecological benign diseases with chronic renal deficiency group, and chronic renal deficiency group were significantly increased compared with the benign gynecological diseases and normal control groups, showing a significant difference (P < 0.001). A comparison of 4 groups with high HE4 showed that the HE4 level in the 2 groups with renal deficiency were higher than those in the ovarian cancer and endometrial cancer groups, but the difference was not significant (P > 0.05); there was no significant difference between 2 groups with renal deficiency (P > 0.05). Serum concentration of HE4 was high in patients with chronic renal deficiency, which should be distinguished during differential diagnosis of gynecological benign and malignant tumors in patients with chronic renal deficiency to avoid misdiagnosis.

RESUMO

OBJECTIVE: Elevated serum IgG4 levels are an important hallmark for diagnosing IgG4-related disease (IgG4-RD), but can also be observed in other diseases. This study aimed to compare two different testing methods for IgG4: ELISA and nephelometric assay. Both assays were used to measure serum IgG4 concentrations, and to assess the prevalence of high serum IgG4 levels in both IgG4-RD and non-IgG4-RD diseases. METHODS: A total of 80 serum samples were tested using the nephelometric assay and ELISA method that we established. Serum IgG4 concentrations were determined by ELISA for 957 patients with distinct diseases, including 12 cases of IgG4-RD and 945 cases of non-IgG4-RD. RESULTS: IgG4 levels from 80 selected serum samples examined by ELISA were in agreement with those detected using the nephelometry assay. Meanwhile, the serum IgG4 concentrations measured by ELISA were also consistent with the clinical diagnoses of patients with IgG4-RD during the course of disease. The Elevated levels of serum IgG4 (>1.35 g/L) were detected in all IgG4-RD (12/12) patients, and the prevalence of high IgG4 serum levels was 3.39% in non-IgG4-RD cases. Among them, the positive rates of serum IgG4 were 2.06% in patients with carcinoma and 6.3% in patients with other non-IgG4 autoimmune diseases. CONCLUSION: Our established ELISA method is a reliable and convenient technique, which could be extensively used in the clinic to measure serum IgG4 levels. High levels of IgG4 were observed in IgG4-RD. However, this phenomenon could also be observed in other diseases, such as carcinomas and other autoimmune diseases. Thus, a diagnosis of IgG4 disease cannot only be dependent on the detection of elevated serum IgG4 levels.

RESUMO

BACKGROUND: Proper folliculogenesis is fundamental to obtain a competent oocyte that, once fertilized, can support the acquisition of embryo developmental competence and pregnancy. MicroRNAs (miRNAs) are crucial regulators of folliculogenesis, which are expressed in the cumulus-oocyte complex and in granulosa cells and some can also be found in the bloodstream. These circulating miRNAs are intensively studied and used as diagnostic/prognostic markers of many diseases, including gynecological and pregnancy disorders. In addition, serum contains small amounts of cell-free DNA (cfDNA), presumably resulting from the release of genetic material from apoptotic/necrotic cells. The quantification of nucleic acids in serum samples could be used as a diagnostic tool for female infertility. METHODS: An overview of the published literature on miRNAs, and particularly on the use of circulating miRNAs and cfDNA as non-invasive biomarkers of gynecological diseases, was performed (up to January 2014). RESULTS: In the past decade, cell-free nucleic acids have been studied for potential use as biomarkers in many diseases, particularly in gynecological cancers, ovarian and endometrial disorders, as well as in pregnancy-related pathologies and fetal aneuploidy. The data strongly suggest that the concentration of cell-free nucleic acids in serum from IVF patients or in embryo culture medium could be related to the ovarian hormone status and embryo quality, respectively, and be used as a non-invasive biomarker of IVF outcome. CONCLUSIONS: The profiling of circulating nucleic acids, such as miRNAs and cfDNA, opens new perspectives for the diagnosis/prognosis of ovarian disorders and for the prediction of IVF outcomes, namely (embryo quality and pregnancy).

RESUMO

The aim of this study is to evaluate the diagnostic performance of human epididymis protein 4 (HE4), cancer antigen 125 (Ca125) and the risk of ovarian malignancy algorithm (ROMA) in discriminating ovarian cancer from other benign gynaecological diseases. Serum levels of HE4 and Ca125 were measured in 119 women with benign gynaecological diseases, 29 patients with primary ovarian cancer, 32 patients with ovarian cancer on chemotherapy treatment (18 of them with progressive disease), 6 patients treated and free of disease and 32 healthy women. Sensitivity, specificity, positive and negative predictive values and positive and negative likelihood ratios (LR ±) were calculated. Receiver operator characteristic (ROC) curves were constructed, and the areas under the curve (AUC) were calculated. High serum levels for HE4, Ca125 and ROMA were observed in cancer patients. HE4 was elevated in 12.6 %, Ca125 in 21 % and ROMA in 9.2 % in the benign group, but HE4 was not elevated in endometriosis. The AUC values for HE4, Ca125 and ROMA were 0.92, 0.911 and 0.945 respectively. The sensitivity for discriminating ovarian cancer from benign gynaecological diseases was 86.2 % for HE4 and Ca125 and 93.1 % for ROMA. The specificity was 87.4, 78.9 and 90.7 % for HE4, Ca125 and ROMA. The overall positive likelihood ratio (LR+) was 6.84 for HE4, 4.1 for Ca125 and 10.01 for ROMA. In premenopausal women, LR + was 11.86 for HE4, 5.11 for ROMA and 2.02 for Ca125. HE4 might be significant in the differential diagnosis of ovarian cancer. HE4 seems to be superior to Ca125 in terms of diagnostic performance of all premenopausal women. ROMA could help to discriminate in cases with any doubt with a high diagnostic accuracy.

RESUMO

OBJECTIVE: This study measured the human epididymis protein 4 (HE4) and CA125 levels in Chinese women with benign gynecological disorders. MATERIAL AND METHODS: Sera were obtained from Chinese women prior to surgery for a pelvic mass and HE4 and CA125 levels were determined. The proportions of patients with HE4 and CA125 levels were compared. RESULTS: There were 68 Chinese women with benign diseases. HE4 levels were less elevated than CA125 (1% V.S. 29%, P<0.001). The significant difference was observed in patients with endometriosis/endometriomas in which HE4 was not elevated patients and CA125 was elevated in 53% (P<0.001). Serum HE4 level was not elevated in patients with cystadenoma (0% V.S. 23%, P<0.001) and in patients with germ cell tumors (0% V.S. 5%, P<0.001). CONCLUSION: HE4 was less elevated and more suitable as a biomarker than CA125 in chinese women with benign disease.

RESUMO

BACKGROUND: Human HIV-1 TAT interactive protein 2 (HTATIP2/TIP30) is an evolutionarily conserved gene that is expressed ubiquitously in human tissues and some tumor tissues. This protein has been found to be associated with some gynecological cancers; as such, this study aimed to investigate blood HTATIP2/TIP30 levels in patients with ovarian cancer. METHODS: Twenty-three women with ovarian cancer and 18 patients with various non-cancerous gynecological complaints (for example, dysfunctional uterine bleeding, fibroids, and urinary incontinence) were included in the study. The pathological diagnosis of ovarian cancer was adenocarcinoma. HTATIP2/TIP30 concentration in the patients' blood samples was determined using ELISA kits. RESULTS: The HTATIP2/TIP30 level was significantly higher in the cancer group than in the control group (1.84 ± 0.82 versus 0.57 ± 0.13 ng/ml, mean ± SD). CONCLUSIONS: We demonstrated the potential role of HTATIP2/TIP30 in ovarian cancer for the first time, thereby enlightening future studies targeting HTATIP2/TIP30 in ovarian cancer treatment, diagnosis, and prevention.

RESUMO

Anti-mullerian hormone (AMH) is a glycoprotein produced by granulosa cells of primary, pre-antral and small antral ovarian follicles and its clinical applicability has been recently demonstrated by several studies. Prediction of the response to ovarian stimulation for in vitro fertilization corresponds to the most frequent utilization of AMH in clinical practice, being routinely assessed in many services to identify subgroups of women susceptible to a poor response or to Ovarian Hyperstimulation Syndrome. There are great perspectives that AMH may be applicable to the individual determination of risk for iatrogenic gonadal injury in women with neoplasms who will be submitted to chemotherapy. It is also probable that AMH assessment will be included in protocols for the investigation of amenorrhea and oligomenorrhea, since AMH levels are increased in Polycystic Ovary Syndrome, reduced in premature ovarian failure and normal in other conditions such as hyperprolactinemia and hypogonadotropic hypogonadism. It is possible that AMH will be utilized in the future for the prediction of age at menopause and of reproductive prognosis, providing solid bases for pre-conceptive and contraceptive counseling.

RESUMO

O hormônio antimülleriano (AMH) é uma glicoproteína produzida pelas células granulosas de folículos ovarianos primários, pré-antrais e pequenos folículos antrais e ultimamente sua aplicabilidade clínica tem sido demonstrada através de diversos estudos. A predição da resposta à estimulação ovariana para fertilização in vitro corresponde a sua mais frequente utilização na prática clínica, sendo rotineiramente realizada em muitos serviços para identificar subgrupos de mulheres suscetíveis a má resposta ou a Síndrome da Hiperestimulação Ovariana. Existem perspectivas de que o AMH possa ser aplicável na individualização do risco de injúria gonadal iatrogênica em mulheres portadoras de neoplasia que serão submetidas a quimioterapia. Também é provável que as dosagens de AMH sejam incluídas nos protocolos de investigação de amenorreias e oligomenorreias, uma vez que seus níveis encontram-se elevados em pacientes portadoras da Síndrome dos Ovários Policísticos, reduzidos em casos de falência ovariana prematura e normais em outras condições como a hiperprolactinemia e o hipogonadismo hipogonadotrófico. É possível que futuramente o AMH venha a ser utilizado na predição da idade de menopausa e do prognóstico reprodutivo da mulher, fornecendo bases sólidas ao aconselhamento conceptivo e contraceptivo.

RESUMO

OBJECTIVES: Under a constant inspired concentration, the uptake of a volatile anesthetic into the arterial blood should mainly be governed by alveolar ventilation, according to the assumption that the patient's cardiac output remains stable during anesthesia. We investigated whether ventilation volume affects the rate of desflurane uptake by examining arterial blood concentrations. METHOD: Thirty female patients were randomly allocated into the following three groups: hyperventilation, normal ventilation and hypoventilation. Hemodynamic variables were measured using a Finometer, inspiratory and end-tidal concentrations of desflurane were measured by infrared analysis, and the desflurane concentration in the arterial blood (Ades) was analyzed by gas chromatography. RESULTS: During the first 10 minutes after the administration of desflurane, the Ades was highest in the hyperventilation group, and this value was significantly different from those obtained for the normal and hypoventilation groups. In addition, hyperventilation significantly increased the slope of Ades-over-time during the first 5 minutes compared with patients experiencing normal ventilation and hypoventilation, but there were no differences in these slopes during the periods from 5-10, 10-20 and 20-40 minutes after the administration of desflurane. This finding indicates that there were no differences in desflurane uptake between the three groups after the first 5 minutes within desflurane administration. CONCLUSIONS: Hyperventilation accelerated the rate of the rise in Ades following desflurane administration, which was time-dependent with respect to different alveolar ventilations levels.

RESUMO

OBJECTIVE: The human epididymis protein 4 (HE4) is a novel biomarker for ovarian cancer. This study measured the HE4 and CA125 levels in women with benign gynecological disorders. STUDY DESIGN: Sera were obtained from women prior to surgery for a pelvic mass and HE4 and CA125 levels were determined. The proportions of patients with elevated biomarker levels were compared. RESULTS: There were 1042 women with benign disease. HE4 levels were less often elevated than CA125 (8% vs 29%, P < .001). A marked difference was observed in patients with endometriosis in which HE4 was elevated in 3% of patients and CA125 in 67% (P < .0001). Serous ovarian tumors were associated with elevated levels of HE4 in 8% of patients and CA125 in 20% (P = .0002); uterine fibroids in 8% vs 26% (P = .0083); dermoids in 1% vs 21% (P = .0004); and inflammatory disease in 10% vs 37% (P = .014). CONCLUSION: HE4 is elevated less frequently than CA125 in benign disease, particularly in premenopausal patients.

RESUMO

The aim of this study is to evaluate a new tumour marker, HE4, in comparison with CA 125 and the Risk of Ovarian Malignancy Algorithm (ROMA) in healthy women and in patients with benign and malignant gynaecological diseases. CA 125 and HE4 serum levels were determined in 66 healthy women, 285 patients with benign gynaecological diseases (68 endometriosis, 56 myomas, 137 ovarian cysts and 24 with other diseases), 33 patients with non-active gynaecological cancer and 143 with active gynaecological cancer (111 ovarian cancers). CA 125 and HE4 cut-offs were 35 U/mL and 150 pmol/L, respectively. ROMA algorithm cut-off was 13.1 and 27.7 for premenopausal or postmenopausal women, respectively. HE4, CA 125 and ROMA results were abnormal in 1.5%, 13.6% and 25.8% of healthy women and in 1.1%, 30.2% and 12.3% of patients with benign diseases, respectively. Among patients with cancer, HE4 (in contrast to CA 125) had significantly higher concentrations in ovarian cancer than in other malignancies (p < 0.001). Tumour marker sensitivity in ovarian cancer was 79.3% for HE4, 82.9% for CA 125 and 90.1% for ROMA. Both tumour markers, HE4 and CA 125 were related to tumour stage and histological type, with the lowest concentrations in mucinous tumours. A significantly higher area under the ROC curve was obtained with ROMA and HE4 than with CA 125 in the differential diagnosis of benign gynaecological diseases versus malignant ovarian cancer (0.952, 0.936 and 0.853, respectively). Data from our population indicate that ROMA algorithm might be further improved if it is used only in patients with normal HE4 and abnormal CA 125 serum levels (cancer risk for this profile is 44.4%). ROMA algorithm in HE4 positive had a similar sensitivity and only increases the specificity by 3.2% compared to HE4 alone.
