Objective: To evaluate the predictive value of separate and combined tests using cell-free fetal DNA (cffDNA), cell-free total DNA (cfDNA), and biochemical markers for the early detection of pregnancies with hypertensive disorders.Methods: A nested case-control study was conducted with 135 singleton pregnancies including 17 gestational hypertension cases, 34 preeclampsia (PE) cases, and 84 controls. We performed real-time quantitative PCR to measure levels of DSCR3 and RASSF1A as cffDNA markers and HYP2 as a cfDNA marker in the first and early second trimesters. Levels of pregnancy-associated plasma protein A (PAPP-A), α-fetoprotein, β-human chorionic gonadotropin, unconjugated estriol, and inhibin A were also determined.Results: Compared with controls, the median levels and multiples of the median (MoM) values of HYP2 were significantly higher in the PE and hypertensive disorders of pregnancy (HDP) groups at 6-14 and 15-23 weeks. Frist-trimester PAPP-A MoM was significantly lower in PE and HDP than in controls. For PE and HDP, the best model included the first-trimester DSCR3, HYP2, and PAPP-A MoM values achieving detection rates of 67 and 58% at a fixed 10% false-positive rate, respectively [area under the receiver operating characteristic curve 0.832 (95% CI 0.689-0.928) for PE; 0.751 (0.607-0.863) for HDP].Discussion: The study demonstrates the potential utility of combined first-trimester cffDNA, cfDNA, and PAPP-A for the early prediction of PE.

Background/Aims: The purpose of this study was to identify predictive markers for tubo-ovarian abscess (TOA) through a comparison of clinical and laboratory data in patients diagnosed with pelvic inflammatory disease (PID). Methods: We reviewed the medical charts of 499 females who were admitted to hospital with clinical, surgical, imaging-based diagnoses of PID between 2001 and 2011. The patients were divided into the following two groups: (1) PID with TOA and (2) PID without TOA. Results: The TOA and non-TOA groups were comprised of 69 and 430 females, respectively. Mean age, history of intrauterine device (IUD) insertion and inflammatory markers, including erythrocyte sedimentation rate, C-reactive protein (CRP) and CA-125 levels, were higher in the TOA group than the non-TOA group. Independent factors that predicted TOA were older age, IUD insertion, increased CRP and CA-125, and chlamydia infection. CA-125 was found to have the highest predictive value for TOA. TOA size was associated with increased surgical therapy compared to patients with smaller abscesses. Conclusions: Increased age, IUD insertion, chlamydia infection, and increased CRP and CA-125 level were the independent factors predictive of TOA in acute PID. These predictive values will be expected to help decrease gynecological morbidity by early diagnosis and appropriate treatment of TOA. [ABSTRACT FROM AUTHOR]
