妊娠32週齢以下の早産児における気管支肺異形成(BPD)発症の出生後危険因子を同定する。 2017年中にSoochow大学小児病院の新生児集中治療室(NICU)に入院した72名の早産児(BPDを有する30名、BPDを有さない42名の対照者)を、この前向き縦断研究に登録した。周産期臨床データ,新生児重症度スコア(NCIS),異なる可溶性 B7-H3(sB7-H3),生後数日ごとのインターロイキン-18(IL-18)レベルを収集した.多重ロジスティック回帰分析を用いて臨床データに基づいてBPD発症の早期予測モデルを構築した。また、モデルの感度と特異度をROC曲線で評価した。 電解質障害,血行動態学的に有意な動脈管閉鎖不全症(hs-PDA),生後40日以上で経腸栄養により120kcal/kg.d.を達成した年齢がBPD発症と関連していることが明らかになった。血清sB7-H3、IL-18、NCISはBPD群で非BPD群と比較して有意に高かった(<0.05)。BPD 群では,生後 1 日目,7 日目,14 日目,28 日目の経腸栄養およびカロリー摂取量が非 BPD 群に比べて有意に低かった.危険因子を重ロジスティック回帰で解析し,sB7-H3(7日目),IL-18(14日目),NCIS,臨床危険因子を組み合わせた予測モデルをROC曲線で評価した. BPDの原因は多因子性の産後危険因子であることが示唆された。また、sB7-H3(7日目)、IL-18(14日目)、NCIS、臨床的危険因子(電解質異常、hs-PDA、生後40日以上で経腸栄養120kcal/kg.dを達成した年齢)の組み合わせは、BPD発症の最適な予測モデルとなる可能性がある。
To identify postnatal risk factors for bronchopulmonary dysplasia (BPD) development in preterm infants with gestational age ≤32 weeks. Seventy-two preterm infants(30 with BPD and 42 non-BPD controls) admitted in the neonatal intensive care unit (NICU) of the Children's Hospital of Soochow University during 2017 were enrolled in this prospective longitudinal study. Perinatal clinical data, a neonatal critical illness score (NCIS), different soluble B7-H3(sB7-H3), and interleukin-18 (IL-18) levels by days after birth were collected. An early predictive model for BPD development was established based on clinical data using multiple logistic regression analysis. And the sensitivity and specificity of the model were assesed by ROC curve. Electrolyte disturbances, hemodynamically significant patent ductus arteriosus (hs-PDA), and the age that infants achieved 120 kcal/kg.d via enteral feeding ≥40 days after birth were found to be associated with the BPD pathogenesis. Serum sB7-H3, IL-18, and NCIS were significantly higher in the BPD group compared to the non-BPD group ( < 0.05). BPD group had significantly lower enteral fluid and caloric intake compared to the non-BPD group at 1, 7, 14, and 28 days after birth. The risk factors were analyzed by multiple logistic regression and a predictive model of a combination of sB7-H3 (day 7), IL-18 (day 14), NCIS, and clinical risk factors was evaluated via ROC curve with an area under the curve (AUC) of 0.960 having sensitivity of 86.7% and a specificity of 97.6%, respectively. The causes of BPD are multifactorial postnatal risk factors. And the combination of sB7-H3 (day 7), IL-18 (day 14), NCIS, and clinical risk factors (electrolyte disturbances, hs-PDA, and the age that infants achieved 120 kcal/kg.d via enteral feeding ≥40 days after birth) might be served as an optimal predictive model for the occurrence of BPD.
