Aim: Hypoxic-ischemic encephalopathy is associated with damage to deep gray matter; however, white matter involvement has become recognized. This study explored differences between patients and clinical controls on diffusion tensor imaging, and relationships between diffusion tensor imaging and neurodevelopmental outcomes. Method: Diffusion tensor imaging was obtained for 31 neonates after hypoxic-ischemic encephalopathy treated with therapeutic hypothermia and 10 clinical controls. A subgroup of patients with hypoxic-ischemic encephalopathy (n = 14) had neurodevelopmental outcomes correlated with diffusion tensor imaging scalars. Results: Group differences in diffusion tensor imaging scalars were observed in the putamen, anterior and posterior centrum semiovale, and the splenium of the corpus callosum. Differences in these regions of interest were correlated with neurodevelopmental outcomes between ages 20 and 32 months. Conclusion: Therapeutic hypothermia may not be a complete intervention for hypoxic-ischemic encephalopathy, as neonatal white matter changes may continue to be evident, but further research is warranted. Patterns of white matter change on neonatal diffusion tensor imaging correlated with neurodevelopmental outcomes in this exploratory pilot study.

Early neurological assessment in infants with hypoxic ischemic encephalopathy (HIE) treated with hypothermia has not been systematically explored. The aims of the present study were to assess whether the Hammersmith Infant Neurological Examination (HINE) is a good tool to predict later neurodevelopmental outcomes at 2 year from birth in this population of infants. A total of 41 term born infants with HIE treated with hypothermia performed the HINE at 12 months and a neurodevelopmental assessment at 24 months. All the infants who had a global HINE score between 67 and 78 were able to walk independently at 2 years and reported a normal developmental quotient; language disorders were observed in a limited number of infants. HINE scores <67 were always associated with motor impairment. In conclusion, the HINE confirms its role as one of the early neurological examination tools for the diagnosis of high risk infants, even in infants with HIE treated with hypothermia. These results can be useful for clinicians involved in the follow up of these infants for early identification of motor disabilities and in planning appropriate intervention.

Background: Among term infants, hypoxic-ischemic encephalopathy due to acute perinatal asphyxia remains an important cause of neurodevelopmental deficits in childhood. Treatment is currently limited to supportive intensive care, without any specific brain-oriented therapy. Objective: To determine whether the risk of death or moderate/severe neurodevelopmental impairment in term infants with hypoxic-ischemic encephalopathy increases with relatively high skin or rectal temperature between 12 and 72 hours of birth. Materials and Methods: This was a prospective observational study. Asphyxiated newborns who came within 12 hours of birth were enrolled in this study. Both axillary and rectal temperature were recorded 6 hourly for 72 hours and each infant`s temperature for each site were rank ordered. Then mean of all axillary and rectal temperatures of each neonate was calculated. Outcomes were related to temperatures in logistic regression analyses for the elevated/relatively high temperatures and normal/low temperatures group, with adjustment of the level of encephalopathy and gender. Results: The mean axillary temperature was 36.07 ± 6.10C and in 25.71%, 11.92% and 6.32% cases axillary temperatures were >370C, >37.50C and >380C respectively. The mean rectal temperature was 36.8 ± 60C, and in 43.53%, 30.02% and 19.97% cases rectal temperatures were >370C, >37.50C and >380C respectively. Mean ambient temperature was 26.170C. There was significant correlation between axillary and rectal temperatures (r=0.889). For elevated temperature, the odds of death or moderate to severe impairment increased 8.9-fold (CI 0.906–88.18) and the odds of death alone increased 4.6-fold (CI 0.373–56.83). The odds of impairment increased 1.84-fold (CI 0.45– 7.50). Conclusion: Relatively high temperature during usual care after hypoxic-ischemia in term neonates was associated with adverse neurodevelopmental outcomes. J Enam Med Col 2019; 9(3): 160-165

Introduction: Accurately diagnosing and treating infants with mild forms of hypoxic ischemic encephalopathy (HIE) is important, as the majority of neonates with signs and symptoms of HIE after birth do not meet clinical criteria for moderate or severe disease. Emerging evidence, however, suggests that infants with mild HIE (mHIE) have an increased risk for neurodevelopmental impairment (NDI). Methods: This retrospective descriptive study examined all inborn infants ≥35 week’s gestational age at a single, level III neonatal intensive care unit (NICU) in California between January 1, 2012, and December 31, 2015. International Classification of Diseases codes were used as a proxy to identify neonates with mHIE but who did not receive therapeutic hypothermia (TH). Short- and long-term neurodevelopmental outcomes were documented, including abnormal (1) brain magnetic resonance imaging within 10 days of birth suggestive of HIE, (2) electroencephalogram with electrographic seizures, (3) neurologic discharge examination, or (4) NDI following NICU discharge. Results: Over the 4-year study period, 25 infants met inclusion criteria. Eight of 25 (32%) infants demonstrated neurologic impairment, defined by an abnormality in at least one of the four categories. The remaining 17 infants were without documented evidence for adverse outcomes. Conclusion: Our results indicate that children with mHIE are at significant risk for neurologic injury and may benefit from more aggressive interventions. Further prospective studies should be completed to determine the efficacy of TH in this specific patient population.

Troponin I is a biomarker for cardiac injury in children. The role of troponin I in neonatal Hypoxic–Ischemic encephalopathy (HIE) may have valuable clinical implications. Troponin I levels were measured within 6 h of birth to determine their relationship to HIE stage, short-term cardiac functional outcomes, and neurodevelopmental outcomes at 1 year. Seventy-three patients were divided into two groups: mild HIE and moderate to severe HIE. Troponin I levels within 6 h of birth were obtained in 61 patients, and were significantly higher in patients with moderate to severe HIE than in patients with mild HIE (Mann–Whitney U test, U = 146, p = 0.001). A troponin I cut-off level of ≥60 pg/mL predicted moderate to severe HIE with a specificity of 81.1% and a negative prediction rate of 76.9%. A troponin I cut-off level of ≥180 pg/mL was significantly (χ2 (1, n = 61) = 33.1, p = 0.001, odds ratio 96.8) related with hypotension during first admission and significantly (χ2 (1, n = 61) = 5.3, p = 0.021, odds ratio 4.53) related with abnormal neurodevelopmental outcomes at 1 year. Early troponin I level may be a useful biomarker for predicting moderate to severe HIE, and initialization of hypothermia therapy.

AbstractHypoxic-ischemic encephalopathy (HIE) is a major cause of morbidity and mortality in neonates. Hypoxic-ischemic encephalopathy occurs as a result of a perinatal hypoxic-ischemic event just prior to or during delivery. Therapeutic hypothermia using whole body cooling is the current treatment of choice to reduce brain injury and improve long-term neurodevelopmental outcomes for neonates with HIE. All English language articles published since 2005 in PubMed and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) were analyzed for existing evidence-based methods for whole body cooling. Whole body cooling is effective in the treatment of HIE in term and near-term neonates. Further research is needed to investigate the use of adjunctive therapies in conjunction with whole body cooling for improved neuroprotection.

Background/Aim. The use of color Doppler neurosonography (cD-US) allows simultaneous examination of parenchymal and vascular cerebral structures. Evaluation of cerebral blood flow velocities (CBFV) and vascular resistance are important in assessment of cerebral circulation in neonates with hypoxic ischemic encephalopathy (HIE). The aim of this study was to evaluate the predictive value of cD-US for abnormal neurodevelopmental outcome in the neonates with HIE. Methods. A total of 90 neonates (>32 weeks gestational age) with HIE were enrolled prospectively. All the neonates with HIE were categorized into three grades according to the Sarnat and Sarnat clinical staging system: mild HIE, moderate HIE, and severe HIE. cD-US was performed simultaneously during the first 24 h of life. Neurodevelopment outcome was assessed at 12 months of age in all the neonates. Resluts. The values of CBFV and the values of index resistance (RI) correlated with the severity of HIE (p < 0.0001) and subsequent neurodevelopmental outcome (p < 0.001). We detected a significant difference in values of CBFV and in values of RI between preterm and full-term neonates (p < 0.01). The cut-off value of RI for poor neurodevelopmental outcomes was 0.81. Conclusions. cD-US could be very useful and safe diagnostic tool for assessing severity of HIE and subsequent adverse neurodevelopmental outcome.
