RESUMO

OBJECTIVES: To compare seizure burden between newborn infants treated with therapeutic hypothermia (TH) and those that were not and to compare the need for antiseizure medications (ASM) in a cohort of infants who were diagnosed with neonatal hypoxic-ischemic encephalopathy (HIE). METHODS: This was a retrospective cohort study on infants born after 35 weeks' gestation, diagnosed with moderate to severe HIE, monitored with amplitude-integrated electroencephalography (aEEG) and eligible for TH. Infants born before the implementation of TH in 2008 were compared with infants born thereafter who received TH. Seizure burden was assessed from aEEG as total time in minutes of seizures activity per hour of recording. Other clinical and demographic data were retrieved from a prospective local database of infants with HIE. RESULTS: Overall, 149 of 207 infants were included in the study: 112 exposed to TH and 37 not exposed. Cooled infants had a lower seizure burden overall (0.4 vs 2.3 min/h, P < 0.001) and were also less likely to be treated with ASM (74% vs 100%, P < 0.001). In multivariable regression models, not exposed to TH, having a depressed aEEG background, and having higher Apgar scores were associated with higher seizure burden (incidence rate ratio: 4.78 for noncooled infants, P < 0.001); also, not exposed to TH was associated with a higher likelihood of multidrug ASM (odds ratio: 4.83, P < 0.001). CONCLUSIONS: TH in infants with moderate to severe HIE is associated with significant reduction of seizure burden and ASM therapy.

RESUMO

OBJECTIVES: In a prospective study, we examined the effect of treatment with recombinant tissue plasminogen activator (r-TPA) on survival and morbidity in a series of high-risk children with infectious endocarditis (IE) after prolonged treatment with indwelling catheters. We hypothesized that r-TPA is an adjunctive therapy for dissolution of infected thrombi in drug-resistant IE. STUDY DESIGN: In the prospective 3-year study (1998-2001), we identified high-risk children with chronic illness and prolonged treatment with indwelling catheters who developed IE and overwhelming sepsis. Patients were allocated to receive r-TPA after persistent and enlarging intracardiac vegetations and failure to respond to conventional medical management. Complications associated with treatment, survival, and cardiac morbidity were observed. RESULTS: Seven infants were treated prospectively with r-TPA. All infants responded promptly to treatment, with resolution of the intracardiac vegetations within 3 to 4 days of commencement and without any adverse complications. All patients survived without long-term cardiac morbidity. CONCLUSION: Recombinant tissue plasminogen activator may offer a safe alternative to surgical intervention in the high-risk infant with IE.

RESUMO

Increased survival of extremely low birth weight infants depends on the use of indwelling catheters. These catheters expose the infant to the risk of thrombus formation and line infection. When intracardiac thromboses become infected, the entity is indistinguishable from infective endocarditis and exposes the infant to prolonged sepsis and risk of disseminated infected emboli. Despite prolonged antiinfective therapy and removal of the infected line, resolution of the sepsis and dissolution of the vegetations is frequently not achieved. We describe 2 cases of infective endocarditis in extremely low birth weight infants successfully treated with recombinant tissue plasminogen activator in addition to prolonged antiinfective therapy. Blood cultures became sterile and vegetations disappeared within days of commencing treatment, and there were no systemic complications. A literature search detailed in the article confirms the poor outcome associated with infectious endocarditis in preterm infants. Tissue plasminogen activator may play an important role when standard care has failed.
