The role of second trimester uterine artery Doppler in predicting obstetric and neonatal outcomes in abnormal first trimester maternal serum pregnancy-associated plasma protein-A and free ß-human chorionic gonadotropin values.

AIM: This study aims to determine whether second-trimester uterine artery (UtA) Doppler combined with first-trimester abnormal pregnancy-associated plasma protein-A (PAPP-A) and ß-human chorionic gonadotropin (ß-Hcg) levels predicts adverse obstetric and neonatal outcomes. MATERIALS AND METHODS: This study of 289 pregnant women included 196 with normal PAPP-A and free ß-HCG values (control group) and 93 with abnormal values (study group) in the first-trimester screening test. Second-trimester UtA Doppler sonography was done in these pregnancies. The perinatal prediction and screening potential of UtA Doppler pulsatility index (PI) parameters were examined in the study group. RESULTS: UtA PI >95 percentile increased birth before the 37th week by 4.46 times, birth before the 34th week by 7.44 times, preeclampsia risk by 3.25 times, fetal growth restriction (FGR) risk by 4.89 times, and neonatal intensive care unit (NICU) admission rates by 3.66 times in the study group (p < 0.05 for all). UtA PI >95 percentile had 49.2% sensitivity and 82.1% specificity for birth before 37 weeks. For birth before 34 weeks, sensitivity was 80.0% and specificity 65.0%. FGR has 70.5% sensitivity and 67.1% specificity. Screening for preeclampsia has 66.6% sensitivity and 61.9% specificity. CONCLUSION: Adding UtA Doppler in the second trimester to pregnancies with abnormal PAPP-A and/or free ß-Hcg values in the first trimester may be a useful screening method for adverse outcomes.

In premature rupture of membranes, maternal serum delta neutrophil index may be a predictive factor for histological chorioamnionitis and affect fetal inflammatory markers: A retrospective cross-sectional study.

PROBLEM: We aimed to investigate the predictive value of delta neutrophil index (DNI) for histological choriomanionitis (HCAM) and the effect of maternal inflammatory markers on neonatal outcomes and fetal inflammatory parameters. METHOD OF STUDY: In this retrospective cross-sectional study, 68 pregnant women without HCAM (group 1) and 46 pregnant women diagnosed with HCAM (group 2) were divided into two groups. Demographic stories of the groups; maternal hematological parameters; maternal DNI and systemic inflammatory index (SII) values; outcomes of newborns; fetal inflammatory markers were recorded and compared between groups. RESULTS: Maternal DNI, and SII levels were significantly higher in group 2 (p value < .05 for all). Admission to the neonatal unit (NICU) was higher in group 2 than in group 1 (p = .0001). We found that fetal inflammatory markers were significantly higher in group 2 (p values .001 for CRP, .0001 for DNI, and .002 for leukocyte). Maternal DNI was determined to be significantly diagnostic at a value of ≥1.3 in HCAM (p = .001). We observed that SII had a significant predictive value of 953036.6 (p = .019) for NICU admission. There is also a positive correlation between fetal inflammatory markers and maternal inflammatory markers. CONCLUSIONS: We found that maternal inflammatory markers are high in HCAM, maternal DNI can predict patients who will develop HCAM, maternal SII value can predict NICU admission, fetal inflammatory markers are high in HCAM, and these markers are affected by maternal inflammatory markers.

Comparison of the ratio of second trimester fetal biometric measurements to fetal nasal bone length in fetuses with normal karyotype and trisomy 21.

AIM: In this study, we compared the ratio of second trimester fetal biometric measurements to nasal bone length (NBL) in fetuses with normal karyotype and trisomy 21 to determine their diagnostic prognostic value. MATERIALS AND METHODS: The study included 148 pregnant women who obtained second-trimester ultrasonographic fetal anatomy and had amniocentesis (AS) for fetal karyotyping. The fetal karyotype results divided the groups into normal and trisomy 21 fetuses. Age, obstetric history, first and/or second trimester screening test risk ratios, fetal biometric measurements, and NBL mm, median (MoM) multiples, and percentile values were recorded and compared between groups. RESULTS: BPD/NBL ratios above 9.26 predict trisomy 21 in fetuses with 77.6% sensitivity and 86.1% specificity (p = 0.001). HC/NBL ratios above 34.50 predict trisomy 21 in fetuses with 77.8% sensitivity and 88.8% specificity (p = 0.001). FL/NBL ratios above 6.02 predict trisomy 21 in fetuses with 69.6% sensitivity and 72.2% specificity (p = 0.001). HL/NB ratios above 6.56 predict trisomy 21 in fetuses with 95.5% sensitivity and 47.2% specificity (p = 0.001). The NBL MoM value demonstrated a high diagnostic accuracy for normal-karyotype fetuses (p = 0.021). CONCLUSION: We found that BPD/NBL, HC/NBL, FL/NBL, and HL/NBL ratios differed between fetuses with a normal karyotype and those with trisomy 21, specifically the HC/NBL ratio, which predicted trisomy 21 with good diagnostic accuracy. In identifying normal-karyotype fetuses, the NBL MoM was highly accurate.

The role of haptoglobin in the diagnosis of preeclampsia and HELLP syndrome and in predicting neonatal outcomes.

OBJECTIVE: The study aimed to determine whether maternal serum haptoglobin values could have an effect on predicting diagnosis and neonatal outcomes in preeclampsia and HELLP syndrome. MATERIALS AND METHODS: Hundred sixteen pregnant women who met the inclusion criteria were included in the study. To evaluate whether serum haptoglobin level in maternal blood could be used in early diagnosis of preeclampsia and HELLP syndrome, 49 pregnant women diagnosed with preeclampsia and 13 pregnant women diagnosed with HELLP syndrome were included in the study group, and 54 healthy pregnant women in the control group. The groups were compared regarding maternal serum haptoglobin level, platelet count, ALT, AST, LDH, and uric acid levels. Moreover, the age, obstetric histories, and newborn outcomes of all pregnant women were recorded and compared between groups. RESULTS: The mean haptoglobin values were 0.29 ± 0.23 g/L in the HELLP syndrome group, 1.01 ± 0.52 g/L in the preeclampsia group, and 1.16 ± 0.37 g/L in the control group. The mean haptoglobin result was lower in the HELLP syndrome group compared to the preeclampsia and control groups (p < 0.001). While the differences between HELLP syndrome and the control and preeclampsia groups were statistically significant, no significant difference was determined between the preeclampsia and control groups. There was a significant positive correlation between haptoglobin value with the week of delivery, umbilical cord pH value, and the first and fifth-minute Apgar scores (p < 0.05). CONCLUSION: It was concluded that haptoglobin values could be used together with other biochemical parameters to diagnose HELLP syndrome and predict newborn outcomes.

Are serum delta neutrophil index and other inflammatory marker levels different in hyperemesis gravidarum?

AIM: Hyperemesis gravidarum (HEG) is a condition characterized by nausea and vomiting, fluid electrolyte and acid-base imbalance, dehydration, weight loss, and ketonuria in early pregnancy. The relationship of HEG with inflammation has been studied in many studies. This study aimed to investigate the role of serum delta neutrophil index (DNI), a new inflammatory marker, and other inflammatory markers in demonstrating the disease's presence and severity in HEG patients. MATERIAL AND METHOD: This retrospective study was conducted by accessing the electronic data of 79 pregnant women diagnosed with HEG in a tertiary center between 2017 and 2022 and 100 healthy pregnant women. The demographic characteristics of the study and control groups, as well as the hematological parameters in the complete blood count and the levels of inflammatory markers, were recorded. RESULTS: There was no significant difference between the groups regarding hematological parameters, DNI, platelet-lymphocyte ratio, monocyte-lymphocyte ratio, and systemic inflammation index (p > 0.05). Neutrophil count and neutrophil-lymphocyte ratio (NLR) were higher in the HEG group compared to the control group (p < 0.05). CONCLUSION: This is the first study to determine the relationship between HEG and serum DNI, a new inflammatory marker. We found that serum DNI values in HEG patients were not different from normal pregnancies and did not reflect the presence and severity of the disease. We also found that inflammatory markers other than the NLR were not different from normal pregnancies in HEG patients.

Are the serum delta neutrophil index and systemic inflammatory index useful as predictive parameters for preeclampsia and HELLP syndrome?

OBJECTIVE: We aimed to determine whether the serum delta neutrophil index and other systemic inflammatory index parameters can have an auxiliary effect in the diagnosis when used with other bio chemical markers in preeclampsia and HELLP syndrome and to determine the role of inflammation in the pathogenesis of these diseases. MATERIALS AND METHODS: 121 pregnant women who met the inclusion and exclusion criteria were included in the study. 52 pregnant women diagnosed with preeclampsia and 19 pregnant women diagnosed with HELLP syndrome were included in the study group, and 50 healthy pregnant women were included in the control group. Demographic data, hematological and bio chemical parameters, and inflammatory markers (serum delta neutrophil index - DNI - and systemic inflammatory index parameters) of the groups were recorded and compared between groups. RESULTS: In terms of neutrophil lymphocyte ratio, platelet lymphocyte ratio, and DNI, the HELLP group was different from both groups. The control and preeclampsia groups were similar. In terms of monocyte-to-lymphocyte ratio, the preeclampsia group was different from both groups. The control and HELLP groups were similar. In terms of the systemic inflammatory index, all groups were similar. CONCLUSION: In our study, we found that when maternal serum DNI values are used together with other bio chemical parameters, it can help in the diagnosis of preeclampsia and HELLP syndrome, and inflammation may play a role in the pathogenesis of these diseases.
