The high platelet counts as predictor for early foetal demise

First trimester sCD40L levels associated with adverse neonatal outcomes in euthyroid pregnant women with positive TPOAb

Backgrounds

It remained unclear whether isolated positive thyroid peroxidative antibodies (TPOAb) were associated with adverse maternal and neonatal outcomes. The purpose of this study was to observe adverse neonatal outcomes among euthyroid pregnant women with positive TPOAb and to investigate the underlying risk factors.

Methods

Euthyroid pregnant women with TPOAb positivity were enrolled and followed up in our study. Adverse neonatal outcomes such as preterm birth, low birth weight, and fetal macrosomia were observed. Clinical data in the first trimester were collected and compared between groups with or without adverse neonatal outcomes. Maternal serum soluble CD40 ligand (sCD40L) was also measured at the same time.

Results

A total of 176 euthyroid pregnant women with TPOAb positivity were finally enrolled and analyzed in our study. Thirty-nine (22.16%) euthyroid women with TPOAb positivity were found to have adverse neonatal outcomes. Thirteen participants received assisted reproductive technology (ART) in our study, and seven participants were in the adverse neonatal outcome group. Preterm birth, low birth weight, and fetal macrosomia were the most common comorbidities. The proportion of receiving ART and the levels of sCD40L and platelet were significantly higher in the adverse neonatal outcome group (all P < 0.05). Multivariate regression analysis showed that sCD40L and receiving ART were the independent risk factors for adverse neonatal outcomes. The odds ratio values of sCD40L higher than 5.625 ng/ml were 2.386 [95% confidence interval (CI) = 1.017 to 5.595; P = 0.046] for overall adverse neonatal outcome, 3.900 (95% CI = 1.194 to 12.738; P = 0.024) for preterm birth, and 3.149 (95% CI = 0.982 to 10.101; P = 0.054) for low birth weight.

Conclusions

Approximately one of the four euthyroid women with TPOAb positivity might have adverse neonatal outcomes. Measurement of sCD40L in first trimester might have a predictive value for adverse neonatal outcomes in euthyroid pregnant women with positive TPOAb.

Predicting miscarriage using systemic immune-inflammation index

AIM

To evaluate the clinical significance of the systemic immune-inflammation index (SII) for patients who had miscarriages.

MATERIALS

The retrospective study included 709 pregnant women who had a miscarriage (nonviable intrauterine pregnancy up to 20 weeks of gestation) and 676 women who carried a viable intrauterine pregnancy up to 20 weeks of gestation-serving as the control group. The study and the control group were compared in terms of demographic characteristics, laboratory test results, and SII values. Furthermore, laboratory test results and SII values were compared between patients in the study group and the control group with a history of genital bleeding (threatened abortion).

RESULTS

The mean gestational week of pregnancy was 9.5 ± 3 for the control group and 8.3 ± 2.5 for the study group (p = 0.150). The SII values were higher in the study group than in the control group (p = 0.030). In all participants with a clinical history of genital bleeding, the leukocyte count, neutrophil count, neutrophil-to-lymphocyte ratio (NLR), and SII values were higher in the miscarriage group than the group with viable fetus (p = 0.031, p = 0.003, p = 0.002, p < 0.001). Based on a receiver operating characteristic (ROC) curve analysis, the SII cutoff value for miscarriage was 883.95 (10⁹ /L) (62.6% sensitivity, 62% specificity) in patients with a clinical history of threatened abortion.

CONCLUSION

High SII values in early pregnancy may be used as an additional marker for the prediction of miscarriage, in pregnant women with threatened abortion. Further prediction models including maternal risk factors and multiple markers may be more valuable for clinical practice.
