Background: Hypertensive disorders of pregnancy constitute a major cause of maternal morbidity and mortality. Pre-eclampsia/eclampsia ranks second only to haemorrhage as a specific, direct cause of maternal mortality. A number of markers have been under study for the early detection of this disease. The study aims to evaluate the predictive value of sFlt-1/PlGF ratio for preeclampsia.Methods: This study was conducted in the Department of Gynaecology and Obstetrics of ASCOMS hospital, Jammu for a period of 6 months from Jan 2019 to June 2019. 50 antenatal patients attending the outpatient department with risk factors for developing preeclampsia were enrolled in the study. Their sFlT-1/PIGF ratio was determined at gestational age of 20 weeks to 37 weeks and its predictive value was evaluated.Results: In the present study, 8 patients developed preeclampsia subsequently. The mean sFlt-1/PIGF ratio values were significantly higher in the patients who developed preeclampsia (73.5) than who did not develop the disease (26.07). The positive predictive value at 1 week was 41.66% and negative predictive value was 100%. At 4 weeks, positive predictive value was 66.66% and negative predictive value was 100%.Conclusions: The present study suggests sFlt-1/PIGF ratio values are useful marker was a predictor of preeclampsia and values >38 were associated with preeclampsia. It is more useful in ruling out preeclampsia than ruling in the disease.

Abstract Background This study aims to explore whether plasma endocrine gland-derived vascular endothelial growth factor (EG-VEGF) in the first trimester can be used as a predictor of hypertensive disorders of pregnancy (HDP), and compare it with placental growth factor (PlGF) and soluble fms-like tyrosine kinase-1 (sFlt-1) to evaluate its prediction of HDP value. Methods This is a prospective cohort study that records the medical history of the pregnant women included in the study at 11–13 weeks’ gestation, and analyzes serum biochemical markers including EG-VEGF, PIGF, sFlt-1 and sFlt-1/PIGF. The predictive values of these tests were determined. We used the receiver operating characteristic (ROC) curve to find the optimal cut-off value for each biomarker and compare the operating characteristics (sensitivity, specificity). Logistic regression analysis was used to create a prediction model for HDP based on maternal characteristics and maternal biochemistry. Results Data were obtained from 205 pregnant women. 17 cases were diagnosed with HDP, the incidence rate was 8.2% (17/205). Women who developed HDP had a significantly higher body mass index (BMI) and mean arterial pressure (MAP). Serum EG-VEGF levels in the first trimester are significantly higher in pregnant women with HDP. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value(NPV) of serum EG-VEGF levels more than 227.83 pg/ml for predicting HDP were 43%, 93%, 86% and 62%, respectively. We established a prediction model in the first trimester include maternal BMI, MAP, and EG-VEGF, with an AUC of 0.8861 (95%CI: 0.7905–0.9818), which is better than using EG-VEGF alone (AUC: 0.66). Conclusion This study demonstrated that serum EG-VEGF is a promising biomarker for predicting HDP in the first trimester. It has better predictive performance compared with the currently used biomarkers like PIGF and sFlt-1. Combining maternal clinical characteristics and biochemical tests at 11–13 weeks can effectively identify women at high risk of HDP.

Abstract Introduction Thrombospondin 1, desmoplakin and stratifin are putative biomarkers for the prediction of preterm birth. This study aimed to validate the predictive capability of these biomarkers in patients at risk of preterm birth. Materials and Methods We included 109 women with symptoms of threatened spontaneous preterm birth between weeks 20 0/7 and 31 6/7 of gestation. Inclusion criteria were uterine contractions, cervical length of less than 25 mm, or a personal history of spontaneous preterm birth. Multiple gestations were also included. Samples of cervicovaginal fluid were taken before performing a digital examination and transvaginal ultrasound. Levels of cervicovaginal thrombospondin 1, desmoplakin and stratifin were quantified by enzyme-linked immunosorbent assays. The primary endpoint was spontaneous preterm birth before 34 + 0 weeks of gestation. Results Sixteen women (14.7%) delivered before 34 + 0 weeks. Median levels of thrombospondin 1 were higher in samples where birth occurred before 34 weeks vs. ≥ 34 weeks of gestation (4904 vs. 469 pg/mL, p < 0.001). Receiver operator characteristics analysis resulted in an area under the curve of 0.86 (p < 0.0001). At an optimal cut-off value of 2163 pg/mL, sensitivity, specificity, positive predictive value and negative predictive value were 0.94, 0.77, 0.42 and 0.99, respectively, with an adjusted odds ratio of 32.9 (95% CI: 3.1 – 345, p = 0.004). Multiple gestation, cervical length, and preterm labor had no impact on the results. Survival analysis revealed a predictive period of more than eight weeks. Levels of desmoplakin and stratifin did not differ between groups. Conclusion Thrombospondin 1 allowed long-term risk estimation of spontaneous preterm birth.

Background: Progressive proteinuria implies worsening of the condition in hypertensive disorders of pregnancy and hence its quantification guides clinician in making decision and planning treatment. The gold standard is 24 hour urine protein estimation. Urine sediment cytology, also known as ‘liquid renal biopsy’ identifies and analyses the extent of renal damage.Methods: Objectives of the study were to compare the efficacy of urine dipstick test to 24 hour urine protein estimation in detecting proteinuria in pre-eclampsic patients and to describe the findings in urine sediment examination in assessing proteinuria in above patients. Urine dipstick test and sediment cytology were performed on the urinary samples of 242 pregnant women with high BP recordings (BP>140/90 mm Hg) which were collected and tested in Department of Pathology, Government Medical College, Kottayam during the study period of 18 months. This was compared with 24 hour urine protein values (gold standard).Results: About 154 patients (63.63%) had significant proteinuria of more than 300mg/24hr. Dipstick method showed 78.57% sensitivity and 81.82% specificity for prediction of significant proteinuria. Positive predictive value and negative predictive value of urine dipstick test were 88.32% and 68.57% respectively. Urine sediment examination revealed the presence of casts only in 11.98% of study population. Conclusions: Diagnostic accuracy of automated urine dipstick test in assessing proteinuria was 79.75%. For grade 1 proteinuria, diagnostic accuracy was 79.81%, for Grade 2 it increased to 93.14% and for grade 3 & 4, accuracy was 98.68%. Urine sediment examination didn’t correlate with proteinuria and hence the extent of renal damage in pre-eclampsia.

The sFlt-1/PlGF ratio has high sensitivity and specificity to diagnose preeclampsia (PE) and to predict pregnancy outcome. Especially in patients with preexisting hypertension and/or proteinuria, diagnosis and management of PE is challenging. We studied the predictive value of the sFlt-1/PlGF ratio for the occurrence of adverse outcome in patients with a high prevalence of preexisting hypertension or proteinuria, clinically suspected of having PE. A sFlt-1/PlGF ratio >= 85 was considered to be a positive test. Adverse pregnancy outcome was defined as HELPP syndrome, intra-uterine growth restriction, or perinatal death. The predictive value of adverse pregnancy outcome of preeclampsia based on clinical grounds (clinical PE) or of a positive ratio was compared using a logistic regression model corrected for gestational age at testing. Results: So far 64 patients with a gestational age (GA) of 29.3 wks (range 20-37 wks) were included. 19 had preexisting hypertension, 5 had preexisting proteinuria and 6 had both conditions. At time of measurement 23 patients had clinical PE (4 with a negative ratio) and 30 patients had a positive sFlt-1/PlGF test (11 without clinical PE at testing of whom 7 developed clinical PE within 2 wks). 27% of patients had an adverse outcome of pregnancy. GA between patients with clinical PE or a positive test did not differ. Patients with clinical PE at the time of testing had an odds ratio of 2.5 (95% CI: 0.75 - 7.8) and patients with a positive test had an odds ratio of 6.8 (95% CI;2.1 - 33.9) for an adverse outcome. Patients with clinical PE had an absolute risk for an adverse outcome of 39% (9/23) compared to 46%(14/30) for patients with a positive sFlt-1/PlGF test (p=.075) In patients where the diagnosis of PE is challenging because of preexisting hypertension and/or proteinuria a positive sFlt-1/PlGF is a stronger determinant for poor pregnancy outcome than the clinical diagnosis of PE. An explanation could be that a positive ratio can select patients that will develop PE in the near future and because of misclassification of patients with preexisting hypertension and/or proteinuria.

Abstract Background In anti-cyclic citrullinated peptide antibody-positive (ACPA+) individuals without clinical synovitis (at-risk), to define the critical ultrasound (US) features sufficiently predictive for inflammatory arthritis (IA) to enable logical initiation of therapy. Methods In a single centre prospective cohort, at risk ACPA+ individuals with a new musculoskeletal symptoms underwent an US scan of 38 joints and 18 tendons at first visit. The predictive value of US abnormalities (Power Doppler (PD), Grey Scale (GS), erosion or tenosynovitis (TSV)) for progression to IA was analysed and the best predictive joints determined by Multivariable Cox Regression, adjusted for confounders. The US results were combined with clinical symptoms/findings to produce predictive models. Results Consecutive at-risk ACPA+ individuals (n = 457, mean age 50.3 years old, 74.2% women) were followed up for median of 15.4 months (range 0.1-127.4), a complete dataset with follow-up of at least 6 months was available for 319 of them. 135 (29.5%) developed IA after a median of 11.3 months (range 0.1-111.7). The negative predictive value of a US scan without any abnormality was 82%. In multivariable Cox regression, both PD and TSV were predictive of progression, with respectively hazard ratios of 1.2 (9=0.026) and 1.13 (p = 0.025). All US abnormalities had a high specificity (spec) but only moderate sensitivity (sens), PD was the most specific with a spec/sens of 0.94/0.23, followed by TSV with a spec/sens of 0.91/0.26 but the best area under the curve (AUC) of 0.599 (P = 0.0015). The addition ACPA titre (high compared to low), but not GS, improved spec/sens up to 0.92/0.34 and AUC to 0.964 (p &lt; 0.001). A selection of US and clinical data of 14 joints also improved prediction, with an AUC of 0.670 (p &lt; 0.001) and a spec/sens of 0.65/0.62. A selection of the 34 most predictive features reached the same sens/spec as the ACR/EULAR 2010 classification criteria for RA, showing a spec/sens of 0.80/0.56. Conclusion In at-risk ACPA+ individuals, the presence of sub-clinical US abnormalities are highly specific for progression to IA. The only moderate sensitivity can be improved by using joints or features selection in combination with clinical examination. These results are the first step in providing guidance for which at-risk ACPA+ individuals to treat. Disclosures L.M. Duquenne None. K. Mankia None. L. Garcia Montoya None. A. Di Matteo None. J.

SummaryIn a prospective longitudinal study, 130 primigravidae at risk for preeclampsia were examined and plasma sampling performed in 45 of them. Plasma thrombomodulin (pTM) was sequentially measured at weeks 12, 24 and 32 of gestation and after delivery in 20 primigravidae who developed either mild preeclampsia (n = 8) or gestational hyper-tension (n = 12) between weeks 32 and 39 of gestation and in 25 (age-matched) primigravidae who had uneventful pregnancies. pTM elevations were not observed until week 32 in uneventful pregnancies, but were present by week 24 (p = 0.002) in patients who later developed hypertensive complications. A net individual pTM increase ≥4.2 ng/ml between weeks 12 and 24 (more than 8 times that of normotensive primigravidae) and/or pTM level ≥47.5 ng/ml at week 32 predicted the development of hypertensive complications with 80% accuracy. Serial pTM determinations can be useful to select pregnancies who may benefit from early pharmacological intervention.
