Plurality-dependent risk of severe intraventricular hemorrhage among very low birth weight infants and antepartum corticosteroid treatment.

OBJECTIVE: This study was undertaken to compare the effect of antenatal corticosteroid therapy on the risk for severe intraventricular hemorrhage (IVH grade III-IV) in preterm singleton and multiple very low birth weight (VLBW) infants. STUDY DESIGN: The occurrence of severe IVH was recorded in 5022 singleton, 2032 twin, and 582 triplet infants, delivered at 24 to 32 weeks' gestation, registered in the Israeli National VLBW infant database. Antenatal corticosteroid therapy was defined as complete, partial, or none. RESULTS: The incidence of IVH grade III-IV ranged from 6.8% among singletons receiving complete course to 29.3% in triplets without antenatal corticosteroid treatment. Complete treatment significantly reduced the incidence of IVH in all plurality groups. The adjusted risk for IVH among multiple infants who received a complete course compared with singletons was not significantly different, odds ratio (OR) 1.3, 95% CI 1.0-1.7 for twins and OR 1.5, 95% CI 0.9-2.3 for triplets. CONCLUSION: Complete course of antenatal corticosteroid therapy was independently associated with decreased risk for severe IVH in singleton and in multiple preterm VLBW infants.

The use of piperacillin/tazobactam (in association with amikacin) in neonatal sepsis: efficacy and safety data.

Piperacillin/tazobactam (P/T) has been used in NICU since 1999 as part of the empirical treatment for presumed sepsis. We studied the microbiological and clinical efficacy and safety of P/T use in newborns with sepsis, using a retrospective analysis of medical records of all newborns treated with P/T (in association with amikacin) during 1999-2003. P/T plus amikacin was used for 353 episodes of presumed sepsis occurring in 252 newborns: 105 episodes occurred in 100 newborns treated for 5-14 d while in 248 (70%) episodes the treatment was discontinued after 2-3 d. 123 pathogens were isolated from the blood cultures (40 in the 5-14 d group and 83 in those treated for 2-3 d only). There were 56 Gram-negative, 55 Gram-positive and 12 Candida spp. isolates. Klebsiella spp. (40%) and E. coli (30%) were the most commonly isolated Gram-negative pathogens; coagulase-negative Staphylococcus (CONS) represented 95% of the Gram-positive pathogens isolated. Pathogen eradication was achieved within 48-72 h of therapy in 93% Gram-negative organisms. There were no clinical, laboratory or cranial ultrasound adverse effects associated with P/T use. We conclude that P/T in association with amikacin is microbiologically and clinically efficacious and safe in the treatment of sepsis in newborns.

The fear of necrotizing enterocolitis versus achieving optimal growth in preterm infants--an opinion.

UNLABELLED: Very-low-birthweight (VLBW) infants suffer marked growth delay despite well-intentioned efforts at combining enteral and parenteral nutrition. Fear of necrotizing enterocolitis (NEC) has traditionally influenced neonatologists toward delaying and progressing slowly with enteral feeding, while supporting the infant with parenteral nutrition. Current evidence suggests significant benefits of enteral feeding that is started early and advanced at rates of 20-35 ml/kg/d. CONCLUSION: We conclude that fear of inadequate growth should replace the fear of NEC in guiding nutritional strategies for these infants.

Early weight gain does not decrease the incidence of low birth weight and small for gestational age triplets in mothers with normal pre-gestational body mass index.

OBJECTIVE: To examine if the recommended weight gain of >680 g/week during the first 24 weeks of pregnancy decreases the frequency of adverse birth weight outcomes in triplet mothers with a normal pregravid BMI. STUDY DESIGN: Retrospective observational study of a large sample of triplet mothers with a normal (19.8-26) pregravid BMI. Adequate, average, and inadequate weight gains were defined as >680, 500-680, and <500 g/week. Outcome measures were the incidence of >or=1 SGA infant and total triplet birth weight <4500 g. RESULTS: Of the 1166 triplet mothers, 208 (17.8%) gained >680 g/week during their pregnancy. This presumed adequate weight gain did not reduce the incidence of SGA triplets or that of total birth weight <4500 g, irrespective of parity. These adverse birth weight outcomes were 2 to 3.5 times lower among multiparous compared to nulliparous mothers. CONCLUSION: Early weight gain of >680 g/week in triplet mothers with a normal pre-pregnancy BMI is not associated with a decrease in the incidence of adverse outcomes. Weight gain recommendations in triplet pregnancies should be realistic and associated with a low risk-benefit ratio.

Plurality-dependent risk of respiratory distress syndrome among very-low-birth-weight infants and antepartum corticosteroid treatment.

OBJECTIVE: The purpose of this study was to determine the effect of antenatal corticosteroids on the incidence of respiratory distress syndrome in singleton infants and multiple infants who weigh <1500 g and are delivered at 24 to 32 weeks of gestation. STUDY DESIGN: The incidence of respiratory distress syndrome was established in 4754 singleton infants, 2460 twin infants, and 906 triplet infants. RESULTS: The incidence of respiratory distress syndrome ranged from 58.2% among singleton infants who received a complete course of antenatal corticosteroid to 81.5% in triplets without any treatment. Complete treatment significantly reduced the incidence of respiratory distress syndrome, compared with partial or no treatment (odds ratio, 0.2-0.6). The adjusted risk for respiratory distress syndrome among infants who received a complete course of antenatal corticosteroids compared with singleton infants increased with plurality (odds ratio, 1.4 and 1.8 for twins and triplets, respectively). CONCLUSION: The effect of corticosteroids decreased with increasing plurality. Irrespective of plurality, a complete course of antenatal corticosteroids significantly reduced the incidence of respiratory distress syndrome, whereas partial treatment had the same effect as no treatment.

Neonatal morbidity of very low birth weight infants from multiple pregnancies.

The epidemic of multiple births has translated into a marked rise in very low birth weight infants, who are at risk for major neonatal morbidity and mortality. Gestational age-adjusted comparisons of outcome between singletons and multiples have shown conflicting results. Comparisons that corrected for relevant confounding variables show that twins and singletons have similar risks for early morbidity and mortality. Very low birth weight triplets may have increased risk for neonatal mortality, however. Second-born very low birth weight twins seem to be at risk for increased respiratory morbidity, even in the era of routine antenatal corticosteroids and postnatal surfactant therapy.

Early adequate maternal weight gain is associated with fewer small for gestational age triplets.

OBJECTIVE: To examine whether the recommended weight gain during the first 24 weeks reduces the frequency of SGA triplets. STUDY DESIGN: We used data collected by the Women's Health Division of Matria Healthcare, Inc (Marietta, GA). We studied the frequency of SGA triplets (birth weight <10th percentile by triplet standards) by weight gain, parity, and pregravid BMI category. Adequate weight gain was defined as >16.2 kg at 24 weeks and BMI categories were defined as underweight (<19.8), normal (19.8-26), and obese (BMI>26). RESULTS: We studied 2890 triplet sets. Adequate weight gain reduces the frequency of SGA triplets, irrespective of pregravid BMI category and parity, except for obese nulliparous women. However, the reduced frequency of SGA infants was significant only in underweight nulli-paras (OR 0.3, 95% CI 0.1, 0.9). CONCLUSION: Higher pregravid BMI and parity seem to reduce the occurrence of SGA triplets. However, lean mothers, especially nulliparas, may be the most important target population for nutritional intervention in triplet pregnancies.

Prenatal and postnatal steroid therapy and child neurodevelopment.

In recent years, scientific evidence has accumulated on the potential neuro-toxic effects of perinatal steroid therapy on the incompletely developed brain; therefore, much effort has been directed toward finding the optimal regimen that may reduce lung disease without incurring significant brain injury in fetuses and preterm infants. Current recommendations of the NIH endorse a single course of prenatal steroids in cases of imminent preterm delivery. Postnatal steroid therapy should be limited, according to the American Association of Pediatrics Guide-lines, to selected clinical cases after the first week of life. These cautions aim to decrease possible harmful effects that could affect short- and long-term neuro-developmental outcome in this high-risk population.

The analysis of the influence of birth order and other factors in multiple birth data.

We compare three methods which can be used to analyse the influence of birth order and other factors on health outcomes in multiple birth data. We consider marginal models based on generalized estimating equations (GEE) and two kinds of conditional models; conditional logistic regression (CLR) and mixed effects models (MEM). Although the models may be written similarly, there are differences in both the interpretation and the numerical values assigned to the parameters. Our main conclusion is that GEE and MEM are preferable to CLR since they provide more flexibility in dealing with missing values and covariates. The choice between GEE and MEM is less obvious and depends on the data, the parameter of interest and statistical power.

Current dilemmas in postnatal steroid therapy for chronic lung disease in preterm infants.

Postnatal steroid therapy has been widely used for the prevention and treatment of chronic lung disease in preterm infants. Recently, evidence has accumulated to suggest that the risks of therapy may outweigh the possible benefits. In 2002, the American Academy of Pediatrics and the Canadian Paediatric Society issued guidelines for steroid use. While clarifying a confusing situation, these guidelines have given rise to much controversy. This review will summarize current information on the clinical trials of steroids and also consider the issues surrounding the guidelines.

Neonatal and long-term outcomes of very low birth weight infants from single and multiple pregnancies.

The revolution in artificial reproductive technologies has resulted in a dramatic rise in the incidence of multiple pregnancies. Many of these infants are born prematurely, often extremely so. Consequently, perinatal morbidity and mortality are highly correlated with plurality. The primary mechanism for this increased risk is prematurity. Studies of the relationship between plurality and outcome are frequently hampered by major differences in case mix between singletons, twins and high multiples. For example, high multiples tend to receive earlier prenatal care, receive more antenatal steroids, are more often delivered by Caesarean section and more often suffer from respiratory distress syndrome. However, recent studies that appropriately account for relevant confounding variables have suggested that very low birth weight infants from high multiple pregnancies are at excess risk for mortality when compared with twins and singletons. This article reviews the current available evidence.
