ABSTRACT

OBJECTIVES@#To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China.@*METHODS@#A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups.@*RESULTS@#Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05).@*CONCLUSIONS@#There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

ABSTRACT

Objective To evaluate the value of serum aminoterminal pro-brain natriuretic peptide (NT-proBNP) and interleukin(IL)-6 levels in diagnosis and severity assessment of the preterm infants with respiratory distress syndrome(RDS).Methods Totally 150 preterm infants with RDS who were hospitalized in our center from August 2016 to March 2018 were enrolled in this study as the RDS group. These infants were further divided into grades 1,2,3,and 4 according to chest radiography. In addition,158 preterm infants without RDS hospitalized in our center during the same period were included as the controls (control group). Serum NT-proBNP and IL-6 levels were measured by ELISA on days 1,3,and 7 after birth,and their pulmonary arterial pressure (PAP) was monitored as well.Results Serum NT-proBNP and IL-6 levels in RDS group were significantly higher than those in control group on day 1 (t=-91.04,P=0.000;t=-11.03,P=0.000),day 3 (t=-89.10,P=0.000;t=-9.909,P=0.000),and day 7 (t=-87.91,P=0.000;t=-8.548,P=0.000). There were significant differences in NT-proBNP levels among grades 1,2,3,and 4 on day 1 (F=50.89,P=0.000),day 3 (F=49.16,P=0.000),and day 7 (F=45.45,P=0.000),showing an increasing trend. Serum IL-6 levels showed no significant difference among grades 1,2,3,and 4 on day 1 (F=0.89,P=0.448),day 3 (F=0.76,P=0.518),and day 7 (F=0.85,P=0.469). The PAP of the RDS group on days 1,3,and 7 was (49.3±3.7),(40.1±5.4),and (39.0±2.6)mmHg (1 mmHg=0.133 kPa),which were significantly higher than those of the control group (35.0±2.7)mmHg (t=-90.01,P=0.000),(30.0±3.1)mmHg (t=-81.90,P=0.000),(26.0±3.0)mmHg (t=-88.89,P=0.000). Thus,there was a positive correlation between NT-proBNP and IL-6 levels (r=0.876,P=0.000) and a positive correlation between NT-proBNP and PAP (r=0.916,P=0.000) in preterm infants with RDS.Conclusion Monitoring serum NT-proBN contributes to early diagnosis and disease severity assessment in preterm infants with RDS.

ABSTRACT

<p><b>OBJECTIVE</b>To study the value of amino-terminal pro-brain natriuretic peptide (NT-proBNP) in predicting symptomatic patent ductus arteriosus (sPDA) in preterm infants.</p><p><b>METHODS</b>Preterm infants born at a gestational age (GA) of ≤ 32 weeks and diagnosed with patent ductus arteriosus (PDA) by echocardiography within 48 hours after birth between June 2014 and April 2015 were selected as subjects. Their clinical manifestations were observed, and serum NT-proBNP levels were measured and echocardiography was performed at 3 and 5 days after birth. The infants were divided into sPDA group and asymptomatic PDA (asPDA) group based on their clinical manifestations and the results of echocardiography. The correlations between serum NT-proBNP level and echocardiographic indices were analyzed. Serum NT-proBNP levels were compared between the two groups. The receiver operator characteristic (ROC) curve was applied to determine the sensitivity and specificity of serum NT-proBNP in the prediction of sPDA.</p><p><b>RESULTS</b>A total of 69 preterm infants were enrolled in this study, with 13 infants in the sPDA group and 56 infants in the asPDA group. Serum NT-proBNP level was positively correlated with the diameter of the arterial duct (r=0.856; P<0.05)and the ratio of left atrial diameter to aortic root diameter (LA/AO) (r=0.713; P<0.05). At 3 and 5 days after birth, the serum NT-proBNP levels in the sPDA group were significantly higher than those in the asPDA group (P<0.05). The area under the ROC curve (AUC) for the prediction of sPDA by NT-proBNP levels at 3 days after birth was 0.949 (95% CI: 0.892-1.000; P<0.001), with a cut-off value of 27 035 pg/mL (sensitivity: 92.3%; specificity: 94.6%); the AUC for the prediction of sPDA by NT-proBNP levels at 5 days after birth was 0.924 (95% CI: 0.848-1.000; P<0.001), with a cut-off value of 6 411 pg/mL (sensitivity: 92.3%; specificity: 92.9%).</p><p><b>CONCLUSIONS</b>NT-proBNP may be a quantitative index for shunt volume. The measurement of serum NT-proBNP levels on 3 and 5 days after birth may be useful to predict sPDA in preterm infants.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study changes of plasma motilin concentration and it's effect on enteral nutrition in premature infants.</p><p><b>METHODS</b>The plasma motilin concentration of 72 premature infants was measured within 12 hours after birth before enteral feeding and on day 3 and 7 of life by using radioimmunoassay. Sixteen full-term neonates were enrolled as controls.</p><p><b>RESULTS</b>(1) The plasma concentrations of motilin in premature infants before enteral feeding after birth and on day 3 and 7 were 198.65 +/- 58.42 ng/L, 248.83 +/- 56.00 ng/L, and 376.77 +/- 139.46 ng/L, respectively, which were significantly lower than those in the control group (300.33 +/- 67.15 ng/L, 334.26 +/- 83.81 ng/L, 510.64 +/- 179.85 ng/L) (P < 0.001 or < 0.01). There was positive correlation between the concentration and gestational age, age in day and the volume of milk. On day 7 the level of motilin was higher than the pre-enteral feeding level of the full term control group. (2) The plasma motilin concentration in feeding un-tolerated premature infants group was lower than that in the normal group, especially on day 3 of life (P < 0.05). (3) Early enteral feeding could improve the plasma motilin levels, gastrointestinal motility and nutrition tolerance in premature infants.</p><p><b>CONCLUSIONS</b>The gastrointestinal functions of premature infants are adaptable to enteral nutrition. Early enteral feeding (including minimal enteral nutrition and non-nutritive sucking) can promote adaptive rapid growth and development of intestine.</p>
