Objective:Preterm premature rupture of membranes (PPROM) is closely related with maternal and fetal complications. Therefore, early diagnosis is extremely important to provide maternal and fetal well-being. Many inflammatory markers have been evaluated for their ability to diagnose membrane rupture at early stages. We aimed to investigate the relationship between the platelet-to-lymphocyte ratio (PLR) and preterm premature membrane rupture.Material and Methods:In this study, 121 pregnant women with PPROM and 96 age-matched pregnant women with spontaneous preterm labor who were admitted to our hospital between January 2014 and December 2015 were enrolled. Demographic data, complete blood cell count results, and neonatal outcomes were recorded.Results:The neutrophil and platelet counts were higher in the PPROM group (9948.4±3393.2 vs. 7466.1±1698.5/mm3 and 244.5±60 vs. 210.6±64.8/mm3, respectively, p<0.001). The PLR and neutrophil-to-lymphocyte ratios (NLR) were both significantly higher in the PPROM group (p<0.001). Correlation analysis revealed that the PLR was positively correlated with the NLR (r=0.10, p=0.031). The ability of the PLR to diagnose preterm premature rupture of membranes was evaluated using an ROC curve. The sensitivity and specificity of the PLR was 57.8% and 73.7%, respectively, at a threshold >117.14 (p<0.001).Conclusion:The PLR might be a cost effective, easy to use, and practical marker for the early diagnosis of PPROM, which can help to determine the appropriate waiting time for delivery and provide maternal and fetal well-being.
Epicardial fat thickness, neutrophil-to-lymphocyte ratio, and pentraxin-3 are important markers that provide an additional information beyond that provided by conventional methods in predicting presence and severity of preeclampsia.
Aim
Subclinical hypothyroidism is thought to be associated with adverse pregnancy outcomes but the data is conflicting and generally depends on antibody positivity and treatment. We evaluated the pregnancy outcomes in Turkish population with untreated, antibody negative subclinical hypothyroidism for the first time.
Methods
We searched for 30 015 patients between January 2016 and May 2017 retrospectively. Finally, a total of 930 pregnant women with untreated, antibody negative subclinical hypothyroidism and 7986 controls were included. Demographic characteristics, laboratory findings and pregnancy outcomes, including pregnancy loss, impaired glucose tolerance, gestational diabetes, hypertensive disorders of pregnancy, preterm birth, neonatal intensive care unit admission, placenta previa and abruption, cesarean delivery, low birthweight, Apgar score <7 and premature rupture of membranes were recorded.
Results
Demographic and laboratory characteristics were similar between two groups except thyroid stimulating hormone levels and previous uterine surgery rates. Subclinical hypothyroidism group had an increased risk of pregnancy loss (odds ratio [OR] 2.583; 95% confidence interval [CI] 1.982–3.365; P < 0.001), impaired glucose tolerance (OR 1.952; 95% CI 1.450–2.627; P < 0.001), hypertensive disorders of pregnancy (OR 1.476; 95% CI 1.113–1.923; P = 0.004), neonatal intensive care unit admission (OR 1.620; 95% CI 1.084–2.420; P = 0.019), placenta previa (OR 12.581; 95% CI 5.046–31.363; P < 0.001) and cesarean delivery (OR 1.263; 95% CI 1.091–1.462; P = 0.002).
Conclusion
Subclinical hypothyroidism has worse pregnancy outcomes as compared to euthyroid pregnant women even in antibody negativity. Therefore, we suggest that all pregnant women should routinely be screened in their first antenatal visits for thyroid functions.
Aim: Preterm premature rupture of membranes (PPROM) is not only the most common distinguishable cause of preterm delivery, but is also associated with adverse neonatal outcomes. We determined the platelet indices in PPROM cases and evaluated their relationship to adverse neonatal outcomes. Methods: Fifty patients with PPROM and 50 patients who experienced spontaneous preterm labor at < 37 gestational weeks were evaluated. Complete blood counts, birth weights, Apgar scores, presence of sepsis and respiratory distress syndrome (RDS) and neonatal intensive care unit admission were recorded. Results: Patients with PPROM had increased mean platelet volumes (9.40 vs 10; P = 0.01), plateletcrit (0.19 vs 0.21; P = 0.03) and a higher frequency of neonatal sepsis (18% vs 38%; P = 0.02). Platelet indices in the patient group were compared according to the development of RDS. Plateletcrit values were higher in the RDS positive group (0.23 AE 0.05 vs. 0.21 AE 0.04; P = 0.04). The cut-off value for plateletcrit was determined as > 0.22, and the probability of RDS increased 5.86 times when plateletcrit values exceeded 0.22 (odds ratio 5.86, 95% confidence interval 1.01-32.01; P = 0.04). A one-unit increase in platelet distribution width resulted in a 1.33-fold increase in the risk of RDS (odds ratio 1.33, 95% confidence interval 1.01-1.77; P = 0.04). Conclusion: Mean platelet volumes and plateletcrit significantly increased and plateletcrit had a predictive value for RDS in PPROM cases. Monitoring plateletcrit may be promising for predicting the development of RDS, one of the most common and serious complications of PPROM rupture.
