Performance of a rapid molecular test to detect Chlamydia trachomatis and Neisseria gonorrhoeae in women with pelvic inflammatory disease / Realización de una prueba molecular rápida para detectar Chlamydia trachomatis y Neisseria gonorrhoeae en mujeres con enfermedad inflamatoria pélvica

Objective: The aim of this study was to investigate the prevalence of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) in women with pelvic inflammatory disease (PID) and the usefulness and cost-effectiveness of a rapid molecular test for the diagnosis and clinical management of PID. Methods: This observational study included 75 patients with mild-to-moderate PID (n=33), severe PID (n=29) and non-specific lower abdominal pain (NSAP) (n=13). CT/NG infections were analyzed using a standard and a rapid test. A cost analysis was carried out. Results: Samples of 19 patients (25.3%) were CT/NG positive. Concordance between rapid and standard tests was 100%. No significant differences were observed in the incidence of CT/NG in mild-to-moderate compared to severe PID. Costs differed according only to disease severity. Conclusions: Rapid molecular tests could help with the diagnosis of PID in sexually active women in clinical settings in which a standard technique is not available.(AU)

Circulating Neutrophil Extracellular Traps Are Elevated in Patients With Deep Infiltrating Endometriosis.

Neutrophil extracellular traps (NETs) have been described to be related to the pathogenesis of inflammatory and autoimmune conditions. Endometriosis is currently considered a chronic inflammatory condition. Therefore, we performed a preliminary case-control study to compare the circulating plasma NET levels in patients with surgically confirmed endometriosis (E group, n = 82) and those of patients without surgical findings of endometriosis (C group, n = 35). Venous blood samples were obtained at the time of surgery. Circulating plasma NET levels were assessed as histone-DNA complexes (ie, nucleosomes) by a quantitative sandwich enzyme-linked immunosorbent assay. The results were expressed in arbitrary units. Circulating plasma NET levels were significantly higher in the E group compared with the C group (median [25th; 75th percentiles]): E group: 0.734 [0.484; 1.363]; C group: 0.541 [0.411; 0.653]; P = .005). The subanalysis of E group patients with deep infiltrating endometriosis (DIE group) or without DIE (non-DIE group) showed that plasma NET levels were higher in the DIE group ( P = .02). No differences were observed in NET levels among patients with and without severe pelvic pain or in patients with and without infertility, regardless of the presence of endometriotic lesions. Therefore, our study shows significantly higher NET levels in patients with endometriosis, which seem to be attributed to increased levels in the subgroup of patients with DIE, suggesting that the presence of elevated circulating plasma NET levels may reflect an inflammatory status in this gynecological condition. Further research is warranted to confirm our findings and to assess the exact role of NETs in the pathophysiological mechanisms of endometriosis.

Total Circulating Microparticle Levels After Laparoscopic Surgical Treatment for Endometrioma: A Pilot, Prospective, Randomized Study Comparing Stripping with CO2 Laser Vaporization.

STUDY OBJECTIVE: To evaluate serial generation of microparticles (MPs) after laparoscopic stripping or CO2 laser vaporization in the surgical treatment of patients with ovarian endometrioma (OE). DESIGN: A prospective, randomized, blinded, pilot study (Canadian Task Force classification I). SETTING: Tertiary care university hospital from December 2014 to July 2016. PATIENTS: Thirty women with unilateral OE undergoing laparoscopic surgery. INTERVENTION: Patients were randomly selected to undergo either CO2 laser vaporization (L group) or laparoscopic stripping (S group) of OE. MEASUREMENTS AND MAIN RESULTS: Blood samples were collected before surgery and at 2 hours, 24 hours, 1 month, and 3 months after surgery. An MP generation curve after OE surgery was created. MP generation was greater in the S group than in the L group at all time points evaluated. The MP generation curve showed a significantly higher area under the curve after excisional surgery (p <.05). CONCLUSION: The higher MP levels in the S group suggest an increased inflammation and procoagulant response after this procedure.

Contribution of Amniotic Fluid along Gestation to the Prediction of Perinatal Mortality in Women with Early Preterm Premature Rupture of Membranes.

INTRODUCTION: To evaluate the largest vertical pocket (LVP) of amniotic fluid as a time-dependent factor to predict perinatal mortality in women with early preterm premature rupture of membranes (EPPROM). MATERIAL AND METHODS: Observational cohort study of singleton pregnancies with EPPROM <24 weeks. Termination of pregnancy (TOP) was considered if the LVP was <2 cm at 7 days. The maternal and neonatal characteristics of ongoing pregnancies were recorded. Prediction of perinatal mortality was estimated based on the influence of the LVP as a time-dependent factor after adjustment for maternal age, prior invasive procedure, and gestational age at EPPROM. RESULTS: Of 104 women, 39 requested TOP. Neonatal survival to discharge was 40%, increasing to 74% if pregnancies achieved 24 weeks. LVP at admission <1 cm, latency to delivery, and gestational age at delivery were independent predictors of perinatal mortality. When evaluating the LVP at different time points of gestation, the highest perinatal mortality risk was established at 2 weeks (odds ratio 14.67, p < 0.001) after membrane rupture, being 5.75 (p = 0.05) the week after and 10.93 (p = 0.037) beyond 2 weeks of EPPROM. DISCUSSION: When LVP measurement, gestational age at EPPROM, maternal age, and prior invasive procedure were considered, we found that the worst prognosis related to perinatal mortality was at 2 weeks after EPPROM.

Bowel Preparation Improves the Accuracy of Transvaginal Ultrasound in the Diagnosis of Rectosigmoid Deep Infiltrating Endometriosis: A Prospective Study.

STUDY OBJECTIVE: To compare the accuracy of transvaginal ultrasound (TVUS) with and without bowel preparation (BP) to detect and describe intestinal nodules of deep infiltrating endometriosis (DIE) with laparoscopic findings. DESIGN: A prospective study of paired data (Canadian Task Force classification II.1). SETTING: A tertiary university hospital from November 2014 to November 2015. PATIENTS: A cohort of women awaiting surgery for endometriosis. INTERVENTIONS: The wall of the rectum and the lower sigmoid colon of the patients were evaluated by 2 TVUSs: the first ultrasound was performed without previous BP, and the second was done after a 3-day low-residue diet and two 250-mL enemas 12 hours and 3 hours before TVUS. MEASUREMENTS AND MAIN RESULTS: The presence or absence of rectosigmoid nodules visualized by TVUS with and without BP was compared with laparoscopic results. Forty patients with a mean age of 36.8 ± 5.0 years were included in the study. By comparing the surgical findings histologically confirmed (the presence or absence of bowel nodules and localization) with those of the 2 TVUSs with and without BP, the sensitivity, specificity, and Cohen kappa were 100%, 96%, and 0.95 and 73%, 88%, and 0.61, respectively. Laparoscopy showed that up to 37.5% of patients (15/40) presented bowel involvement. Variables were clearly more evaluable with than without BP. CONCLUSION: TVUS with BP has a higher accuracy than TVUS without BP. BP allows and facilitates the detection of more rectal nodules of DIE in patients with suspected endometriosis and surgical criteria.

Endometriotic Pain Is Associated with Adenomyosis but Not with the Compartments Affected by Deep Infiltrating Endometriosis.

BACKGROUND: The identification of presurgical clinical markers may be helpful to allow the staging of endometriosis severity. It has been suggested that pain characteristics orientate the gynecologist about the anatomical involvement of endometriosis. The study was performed to analyze the correlation between pain symptoms and the anatomical location of endometriosis. METHODS: One hundred fifty-five consecutive patients with a complete removal of deep infiltrating endometriosis (DIE) were included. Prior to surgery, data on patient and disease characteristics were obtained. The intensity of the pain symptoms was registered using a Visual Analogue Scale. The endometriotic lesions were categorized according to the Enzian morphological classification. Correlation and multivariate analysis were performed to assess the potential associations between pain characteristics (dysmenorrhea, pelvic pain, dyschezia, dyspareunia or dysuria) and the location of endometriosis or other disease-related characteristics (hematuria, rectal bleeding or adenomyosis). RESULTS: Pelvic pain was significantly associated with the presence of adenomyosis. Dyschezia was correlated with rectal bleeding and dysuria with the presence of hematuria. No relationship was found between other kinds of pain and the morphological location of endometriosis or other disease-related characteristics. CONCLUSION: Our data suggest that pelvic pain is correlated with the presence of adenomyosis in women with DIE. Further studies are required.

Markers of deep infiltrating endometriosis in patients with ovarian endometrioma: a predictive model.

OBJECTIVE: The purpose of the study was to develop an easily applicable predictive model to predict deep infiltrating endometriosis in patients with ovarian endometrioma. STUDY DESIGN: We performed a retrospective analysis of 178 consecutive women with ovarian endometrioma who underwent surgery, with histological confirmation and complete removal of endometriosis in the Hospital Clinic of Barcelona. Several markers were prospectively obtained and compared between the group of patients presenting deep infiltrating endometriosis associated with ovarian endometrioma and women with only ovarian endometrioma. Multiple logistic regression analysis was performed to create a model to predict the presence of deep infiltrating endometriosis and internal validation was later performed. RESULTS: Of the 178 patients studied, 80 (45%) were classified in the ovarian endometrioma group and 98 (55%) in the group of patients presenting deep infiltrating endometriosis associated with ovarian endometrioma. The independent variables to predict deep infiltrating endometriosis were: at least one previous pregnancy, a past history of surgery for endometriosis and the mean endometriosis-associated pelvic pain score. The area under the ROC curve was 0.91 (95% confidence interval: 0.86-0.94), with an optimal cut-off of the predicted probability of 0.54. The sensitivity of the model was 80% and the specificity 84%. CONCLUSIONS: This model predicts the development of deep infiltrating endometriosis in patients with ovarian endometriomas allowing prioritization of women for referral to specialized centers.

Pertussis vaccination during pregnancy: Antibody persistence in infants.

Maternal pertussis vaccination is associated with higher levels of pertussis antibodies at birth. We assessed the persistence of pertussis antibodies until primary vaccination in infants whose mothers received Tdap (tetanus, diphtheria, acellular pertussis) vaccine during pregnancy. Infants were born at the Hospital Clinic of Barcelona (Spain) in November 2014. Anti-PT IgG was determined by ELISA at delivery, between the first and second month of life, and estimated at 2months of age. The study included 37 infants whose mothers received Tdap between 21 and 38weeks of gestation. Infants presented a decline in GMC of anti-PT IgG between peripartum and follow-up levels, 52.7 (95% CI 34.7-80.2) versus 7.5 (95% CI 4.2-13.3) at 2months of age (p<0.001). The median half-life of maternal antibodies was 47days. More than half (51.4%) the infants presented detectable anti-PT IgG before the start of primary infant vaccination.
