Italian multicentre study on retinopathy of prematurity 总被引:4,自引:0,他引:4
G. Chirico 《European journal of pediatrics》1997,156(12):939-943
The aim of this prospective multicentre study was to evaluate the influence of a number of perinatal factors on the development
of ROP in high risk preterm infants with gestational age ≤30 weeks. All infants consecutively born in, or transferred to,
one of the 14 participating centres from 1 January 1992 through 31 December 1993, who had a gestational age of 30 weeks or
less and no congenital anomalies and survived to the age of 6 months, were included in the study. Of the 380 infants with
mean ± SD gestational age of 28.4 ± 1.6 weeks (range 23–30 weeks) and birth weight of 1157 ± 335 g (range 485–2480 g) that
were eligible for the study, 82 (21.5%) developed ROP stage 1 or 2 and 57 (15%) ROP stage 3 or 3+. Step-wise logistic regression
analysis showed that the following factors had a significant predictive value for the development of ROP stage 3 or 3+: gestational
age (Odds Ratio (OR)=0.6144 for each increment of 1 week of gestational age), birth weight (OR=0.843 for each increment of
100 g of birth weight), prenatal steroids (OR 4.044 for lacking or incomplete prophylaxis), RDS (OR 2.294), oxygen dependency
at 60 days (OR 2.085), necrotising enterocolitis (OR 2.597).
Conclusion This study confirms the role of prematurity, low birth weight and RDS in the pathogenesis of ROP, and emphasises the importance
of prenatal steroid prophylaxis of RDS in very preterm infants. Furthermore, our data suggest that infants with oxygen dependency
at 60 days or necrotising enterocolitis are at very high risk of developing ROP.

Recombinant human erythropoietin in the treatment of infants with anaemia of prematurity 总被引:1,自引:0,他引:1
D. S. Halpérin M. Félix P. Wacker G. Lacourt J. -F. Babel M. Wyss 《European journal of pediatrics》1992,151(9):661-667
Recombinant human erythropoietin (rHuEPO) was administered subcutaneously three times a week to 18i infants with the anaemia of prematurity at doses of 75, 150, 300, or 600 units/kg per week for 4 weeks, starting at 3–4 weeks of postnatal age. A significant and dose-dependent increase in reticulocyte count was observed from a mean baseline value of 71×109/l to 200×109/l after 3 weeks of therapy, compared with a change from 69 to 97×109/l in 66 historical controls. The haematocrit value remained unchanged during rHuEPO treatment, whereas it steadily declined until 9 weeks of postnatal age in the controls. These effects were accompanined by a marked reduction in serum iron concentration and transferrin saturation in patients receiving standard-dose iron supplements, but not in those given larger doses. Only 3 of 18 patients required a red blood cell transfusion. These infants were among the most anaemic at entry into the study and 2 of them were unable to complete rHuEPO therapy, while the third developed iron deficiency anaemia. These data indicate that rHuEPO with appropriate iron supplementation may accelerate the recovery from anaemia of prematurity. Larger scale placebo-controiled studies are now needed to confirm these findings and verify their impact on transfusion requirements of premature infants. 相似文献

Aims
This retrospective, population based study was designed to investigate risk factors for development of retinopathy of prematurity (ROP) and their possible interrelationships, in neonates of gestational age (GA) < 32 weeks born in a well-defined geographical region.Study design—subjects
The study population included all preterm infants born alive with GA 24–32 weeks in Northwestern Greece during a 9-year period and hospitalised in the regional neonatal intensive care unit (NICU).Outcome measurements
The association was assessed of the presence of ROP with maternal factors: age, pathology of pregnancy, in-vitro fertilisation, multiple gestation, mode of delivery, perinatal factors: gender, antenatal steroids, transportation, resuscitation, GA, birth weight (BW), small for GA status and postnatal morbidity: chronic lung disease (CLD), intraventricular haemorrhage (IVH), necrotizing enterocolitis (NEC), respiratory distress syndrome (RDS), maximum O2 needs, hypoxic/hyperoxic episodes, patent ductus arteriosus (PDA), sepsis, using multiple logistic regression analysis.Results
Of 189 infants without congenital anomalies born at GA 24–32 weeks ROP was diagnosed in 24 (12.7%) (> grade 2: 6). Logistic regression analysis showed ROP to be strongly associated with GA, odds ratio (OR) 2.1, confidence interval (CI) 1.3–3.3, p < 0.01 and CLD, OR 10.2, CI 2.3–44, p < 0.01, respectively, independent of confounding factors. By estimating interaction on an additive scale it was shown that the combined risk effect of GA and CLD was larger than the sum of the individual risk effects, implying synergistic effect.Conclusions
ROP was closely and independently related to both low GA and the diagnosis of CLD, which were interrelated in the development of ROP. 相似文献8.

We documented the prevalence of retinopathy of prematurity (ROP) in a group of 46 infants suffering from a moderate or severe respiratory distress syndrome and treated with surfactant replacement therapy (SRT) and 61 controls admitted in the year prior to the institution of SRT. Mortality in the treatment group was lower than in the control group (15.5% versus 23.8;P=0.29). The ROP prevalence in the treatment group was 47.8% and in the control group was 47.8% and in the control group 27.9%. To analyse the contribution of SRT alone to the prevalence of ROP, multivariate analysis using logistic regression technique was used. The odds ratio for SRT was 5.2 with a 95% confidence interval of 1.3–20.7,P=0.02. The prevalence of severe ROP in the surfactant treated group was not increased compared to the control group. From our data we conclude that SRT increases the risk of developing ROP but is not associated with more severe forms of ROP. 相似文献

Aim: To explore the association of serum bilirubin level and breast milk feeding with retinopathy of prematurity (ROP) in preterm infants. Methods: We conducted a case–control study to examine the independent and combined effects of serum bilirubin and breast milk feeding on ROP risk in infants <32 weeks gestation or with birth weight <1500 g. Cases (66 infants with ROP) were matched with controls (66 infants without ROP) based on factors known to affect ROP risk. Results: When analysed using the paired t‐test, the peak bilirubin levels were lower in ROP cases than in controls (mean 7.2 vs. 7.9 mg/dL; p = 0.045). Using conditional logistic regression, we found a negative association between highest serum bilirubin level and risk of ROP (OR = 0.82 per 1‐mg/dL change in bilirubin; p = 0.06). There was no significant association between breast milk feeding and risk of ROP. Conclusion: Bilirubin may help to protect preterm infants against ROP. 相似文献

During a 30-month-period, 184 very low birth weight infants from two Liverpool neonatal intensive care units were screened for evidence of retinopathy of prematurity (ROP). Seventeen clinical variables previously considered relevant to the development of ROP, blood gas and blood pressure data over the first 7 days, and the maximum stage of ROP reached in either eye were recorded, together with the need for cryotherapy and current visual status. Ninety-two infants developed any stage of ROP and 15 required cryotherapy or became blind. Logistic regression showed that only gestational age and frequency of blood transfusion were independently associated both with the risk of occurrence of ROP and its severity. 相似文献

The major known risk factors for retinopathy of prematurity (ROP) are extremely low gestational age, exposure to high levels of oxygen early after birth (phase I) and relatively lower oxygen levels later (phase II). In this review, we summarize recent data suggesting that exposure to perinatal infection/inflammation is associated with an increased risk for ROP. Part of this effect might be due to direct exposure of the developing retina to circulating products of infection and/or inflammation. Another potential mechanism that deserves exploration is that inflammation and/or oxidative stress can modify the known increased risk of oxygen-associated ROP. Taken together, accumulating evidence suggests that prenatal, perinatal, and postnatal systemic inflammation contribute to a 'pre-phase', sensitizing the pre-ROP retina for subsequent insults, setting the stage for what are now called phase I and phase II of ROP pathogenesis. Strategies targeting inflammatory responses might help reduce the risk for ROP in extremely low gestational age newborns. 相似文献

Retinopathy of prematurity (ROP) is a disorder of the developing retinal blood vessels of the preterm infant. New recommendations for screening and treatment of ROP have been published in the past few years. Current evidence suggests that screening infants with gestational ages of 30 6/7 weeks or less (regardless of birth weight) and birth weights of 1250 g or less is a strategy with a very small likelihood that an unscreened baby would have treatable ROP. Individual centres may choose to extend birth weight screening criteria to 1500 g. Initial screening should be performed at 31 weeks' postmenstrual age in infants with gestational ages of 26 6/7 weeks or less at birth, and at four weeks' chronological age in infants with gestational ages of 27 weeks or more at birth by an ophthalmologist skilled in the detection of ROP. Follow-up examinations are conducted according to the ophthalmologist's recommendation. Infants with high-risk prethreshold ROP and threshold ROP are referred for retinal ablative therapy. Developing processes for ROP screening, documenting results and communicating results to parents as well as health professionals involved in the infant's care are important responsibilities for all nurseries providing care for preterm infants. 相似文献
