Abstract
OBJECTIVE: To evaluate TIMP in preterm very low birth weight (VLBW) infants, analyze risk factors, for atypical TIMP (aTIMP) scores, and explore TIMP's predictive relationship with Bayley-III at 2 years. METHOD: A prospective study of 288 VLBW infants, with TIMP assessment between 34 weeks postmenstrual age and 16 weeks age, corrected for prematurity. RESULT: aTIMP scores were observed in 58/288(20%) infants, whose mean birth weight (BW) and gestational age were 1122 ± 257 g and 29.2 ± 2.12 weeks respectively. Risk factors included BW < 750 g (OR 4.8, 95% CI 1.3-17.7) and 750-1000 g (OR 2.9, 95% CI 1.2-6.9), presence of necrotizing enterocolitis ≥ stage 2; or focal intestinal perforation (OR 4.6, 95% CI 1.4-14.4), periventricular leukomalacia (OR 22.4,95% CI 2.0-246.2), and need for intensive resuscitation at birth (OR 2.7, 95% CI 1.3-5.5). aTIMP scores correlated with Bayley-III Score <85 in motor and cognitive domains with high specificity (80-82%) and negative predictive value (85-94%). CONCLUSION: Identification of the risk factors for aTIMP scores will enable targeted intervention to optimize resources and outcomes in VLBW infants.
