[Risk factors involved in the need for blood transfusion in very low birth weight newborns treated with erythropoietin]. / Factores de riesgo implicados en la necesidad de transfusión sanguínea en recién nacidos de muy bajo peso tratados con eritropoyetina.

OBJECTIVE: To identify and quantify risk factors related to red blood cell transfusion in premature babies weighing<1,500g who received erythropoietin (EPO). Secondly, to assess the relationship between retinopathy of prematurity and rh-EPO. MATERIAL AND METHODS: Prospective descriptive study of infants admitted to the Reina Sofía University Hospital between January 2006 and March 2009. Infants reviewed had a birth weight<1,500g and gestational age<32 weeks. Infants were administered rh-EPO 750IU/kg/week subcutaneously 3 days/week/ 6 weeks. We used univariate and multivariate logistic regressions with PASW Statistics 18 for Windows. RESULTS: Data were obtained from 110 infants, with a mean birth weight of 1154grs and mean gestational age of 29.3 weeks. Risk factors (OR; 95% CI) for being transfused were: male sex (4.41; 1.24-15.66), GA (1.64; 1.14-2.36, 1 week), Hb level on admission (1.45; 1.04-2.04; 1g/dl), late onset sepsis (7.75; 2.21-21.11), late onset treatment with rh-EPO (6.27; 1.22-32.35). All surgically treated infants with patent ductus arteriosus ligation or necrotizing enterocolitis needed transfusion. There is no relationship between rh-EPO administration and retinopathy of prematurity (ROP), but there was a relationship with transfusion. CONCLUSIONS: Premature infants with the lower gestational age, being male, a lower Hb level on admission and late onset sepsis are those with the greatest risk for blood transfusion.

[Usefulness of Clinical Risk Index for Babies based on birth weight in predicting hospital death and severe intraventicular hemorrhage in the SEN 1500 Spanish neonatal network]. / Análisis de la utilidad del Clinical Risk Index for Babies por estratos de peso como predictor de muerte hospitalaria y de hemorragia intraventricular grave en la Red Neonatal Española SEN 1500.

OBJECTIVE: To evaluate the usefulness of the Clinical Risk Index for Babies (CRIB) in predicting hospital mortality and severe intraventricular hemorrhage (IVH) in very low birth weight infants stratified by weight groups, in the Spanish neonatal network SEN 1500. PATIENTS AND METHODS: A prospective cohort study was made. Morbidity-mortality data and CRIB were collected in newborns weighing below 1500 g and admitted to 68 neonatal intensive care units between January 2002 and December 2006. Data were analyzed globally and stratified by weight groups (< 501 g, 500-750 g, 751-1000 g, 1001-1250 g, 1251-1500 g). Multivariate models were generated and ROC curves were plotted for estimating predictive values. RESULTS: A total of 10,608 patients were analyzed. The mean weight was 1116 g (SD 267), and gestational age 29.5 weeks (SD 2.9). Low birth weight for gestational age was 34.3% and the multiple birth rate 36%. Prenatal corticoids were given in 78.2%. Severe intraventricular hemorrhage was diagnosed in 8.5%. Gender, prenatal corticoids, birth weight, gestational age and CRIB proved significant for the outcomes. CRIB showed the highest predictive accuracy in all strata (P < 0.001) except in the 501-750 g group, where it was similar to gestational age. Body weight showed the lowest AUC in all groups, except in the 1251-1500 g group, where it was no different to gestational age. Gestational age and CRIB yielded greater AUC values than weight (P < 0.001) in all groups. No significant differences were found between CRIB and gestational age, except in the 751-1000 g group, where gestational age was greater (P = 0.029). CONCLUSIONS: The CRIB is the best predictor among newborns below 1500 g, except in the 501-750 g group, where CRIB is similar to gestational age. Body weight is the worst predictor, except in the group 1251-1500 g, where it is similar to gestational age. The accuracies of CRIB and gestational age in the prediction of IVH are similar, and both superior to body weight. This similarity persists in all the groups, except in the 751-1000 g interval, where gestational age is a better predictor.

[Retinopathy of prematurity. The results after a 1-year follow-up]. / Retinopatía del prematuro. Resultados tras un año de seguimiento.

OBJECTIVE: To analyze prospectively the incidence and outcome of retinopathy of prematurity (ROP) in preterm infants admitted to a neonatal intensive care unit. PATIENTS AND METHODS: A high risk group of infants with birth weights less than 1,500 g, and/or a gestational age less than 30 weeks, was studied. Ophthalmoscopic examination was performed at six weeks of age. Frequent ophthalmoscopic examinations were then performed depending on the gravity of the ROP. RESULTS: ROP was found in 14 of the 20 preterm infants (70%). Two developed stage 3 and none of them stage 4 or 5. Cryotherapy for ROP was not used. None of the infants progressed to advanced stages of ROP and complete resolution was the rule. CONCLUSION: Despite the low incidence of advanced stages of ROP in our study, we suggest that all preterm infants less than 1,500 g and/or 30 weeks of gestational age, should be screened for ROP and repeated ophthalmoscopic examination performed in order to evaluate the progression and treatment of ROP.

[Neonatal systemic candidiasis in the nineties]. / Candidiasis sistémica neonatal en los noventa.

OBJECTIVE: Retrospective study of newborns with systemic candidiasis during the period January 1990-March 1994 admitted to the Neonatology Unit at tertiary hospital. We analyzed the predisposing factors, clinical course, diagnosis, treatment and outcome. MATERIAL AND METHODS: Fourteen newborns were diagnosed of systemic candidiasis on the basis of positive blood culture associated with compatible clinical condition and/or involvement of any organ. All the patients had as predisposing factors the use of broad spectrum antibiotics, prolonged intravascular catheterization and parenteral nutrition, and 12 newborn infants had mechanical ventilation. RESULTS: Twelve newborns were preterm infants, 10 of them weighing less than 1.500 g and 2 were term infants who required abdominal surgery due to ileal atresia and omphalocele. The mean age at onset of systemic candidiasis was 40 days. Clinical presentation was indistinguishable from that of bacterial sepsis. C. albicans was isolated from the blood of 12 infants, from the urine of 6 infants and from the cerebrospinal fluid of two infants. Six infants were treated with intravenous amphotericin, one infant was treated with intravenous amphotericin B associated with oral flucytosine and two infants were treated with liposomal amphotericin. Six of the infants died one of them while still receiving antifungal therapy. CONCLUSION: Systemic candidiasis should be considered in any septic infant mainly preterm infant less than 1.500 g with predisposing risk factors. We truly believe that a high index of suspicion, rapid diagnosis, early initiation of systemic fungal therapy, and removal of indwelling catheters may markedly reduce the mortality and improve the prognosis associated with neonatal systemic candidiasis.
