We compared ibuprofen and indomethacin for the treatment of patent ductus arteriosus (PDA) in preterm infants. A retrospective comparative study was conducted at a pediatric tertiary center in preterm infants diagnosed with PDA. Infants born from January 2000 to June 2003 were treated with indomethacin, whereas infants born from July 2003 to November 2005 were treated with ibuprofen. The two treatment groups were compared. Demographic data and clinical, laboratory, and outcome data were collected from the medical files. Seventy-three infants were included in the ibuprofen group and 46 in the indomethacin group. No significant difference in efficacy was found between indomethacin and ibuprofen. Compared with ibuprofen, indomethacin treatment was associated with significantly higher mean creatinine levels and a higher percent of infants with creatinine >1.2 mg/dL, hyponatremia <120 mmol/L, and platelet level <100,000 platelets/mL(3). There were no significant differences in bilirubin levels, incidence and grade of intraventricular hemorrhage, necrotizing enterocolitis, retinopathy of prematurity, rate of surgical duct ligation, sepsis, length of hospital stay, or mortality. Indomethacin and ibuprofen are equally effective for PDA closure in premature infants. Treatment with ibuprofen is safer, decreasing the risk of renal failure, thrombocytopenia, and hyponatremia.

This study sought to expand current knowledge on the clinical and epidemiological characteristics of persistent coagulase-negative Staphylococcus (CoNS) bacteremia in very-low-birth-weight (VLBW) infants. Background and disease-related data were collected prospectively on 143 VLBW infants diagnosed with CoNS bacteremia at a pediatric tertiary medical center in 1995-2003. Findings were compared between those with persistent (positive blood cultures for >72 h under appropriate treatment ) and nonpersistent disease. Fifty-eight infants (40.6%) were found to have persistent bacteremia. There were no between-group differences in maternal characteristics, mode of delivery, newborn characteristics, dwell time of central venous and umbilical catheters, complications of prematurity, or mean hospital stay. The persistent bacteremia group had significantly higher rates of hypothermia at presentation (37.9% vs. 17.6%, p < 0.04), creatinine >1.2 mg% on treatment day 7 (13.7% vs. 2.4%, p < 0.02; transient phenomenon), and endocarditis (p < 0.03); one infant had an aortic thrombus. Predominantly breast-fed infants had a higher rate of negative cultures within 72 h of appropriate treatment than predominantly formula-fed infants (60% vs. 19%, p < 0.02). In conclusion, persistence of CoNS bacteremia is common in VLBW infants. Endocarditis should be excluded in all infants with persistent disease. Breast-feeding is associated with a shorter disease duration.

AIMVancomycin is widely used to treat late onset coagulase-negative Staphylococcus (CoNS) sepsis in very low birth weight (VLBW) infants. Although vancomycin is associated with a risk of toxicity and bacterial resistance, the appropriate duration of use has not been established. This study sought to investigate the association between the duration of vancomycin therapy and clinical outcome in VLBW infants with CoNS sepsis. METHODSThe files of all VLBW infants treated for CoNS sepsis at a tertiary paediatric medical centre from 1995-2003 were reviewed for clinical data, laboratory variables and outcome. Only patients with two positive diagnostic blood cultures were included. The findings were analyzed by duration of vancomycin treatment after the last positive blood culture. RESULTSThe study cohort included 126 infants, 48 treated for 5 days, 32 for 6-7 days, 31 for 8-10 days and 15 for >10 days. There were no differences among the groups in perinatal characteristics, central catheter dwell time, laboratory data including haematologic, renal and liver function tests, or rate of complications of prematurity. Five infants were diagnosed with infective endocarditis or aortic thrombi and were treated for >10 days. CoNS sepsis recurred in two infants (1.6%). No toxicity of vancomycin treatment was observed.
