Outcome Trajectories after Primary Perinatal Hemorrhagic Stroke.

ABSTRACT:

Background

Perinatal hemorrhagic stroke in late preterm and term neonates is understudied. We describe two-month and two-year neurological outcomes in a prospective cohort.

Methods

Neonates ≥36 weeks' gestation with spontaneous hemorrhagic stroke (parenchymal and intraventricular) presenting at age ≤28 days were enrolled between March 2007 and May 2015 at three tertiary pediatric centers. Hemorrhagic transformation of arterial ischemic stroke or cerebral sinovenous thrombosis was excluded. The Pediatric Stroke Outcome Measure (PSOM) assessed outcomes. Wilcoxon signed-rank tests evaluated change over time.

Results

Twenty-six neonates were included (median age: 1 day, interquartile range [IQR] 0 to 16; median gestational age: 38.3 weeks, IQR 37.0 to 39.0). Hemorrhage was isolated intraventricular in seven (27%), isolated intraparenchymal in six (23%), and a combination in 10 (39%). Three neonates (12%) died during hospitalization; one died later due to cardiac disease. Among 22 survivors, outcomes were assessed at a median of 2.1 months (IQR 1.7 to 3.3) in 96% and 1.9 years (IQR 1.3 to 2.0) in 73%. Median PSOM scores were 0.0 (IQR 0.0 to 1.0) and 0.25 (IQR 0.0 to 1.3), respectively. At two years, 45% of patients had no or nonimpairing deficits (PSOM <1.0), 30% had mild deficits (PSOM 1.0 to 2.0), and 5% had moderate deficits (PSOM 2.5 to 4.5). Over time, 31% worsened and 6% improved. Although total PSOM scores did not change significantly (P = 0.08), language subscores worsened (P = 0.009). No child developed epilepsy.

Conclusions

Perinatal hemorrhagic stroke survivors had favorable outcomes in early childhood; at two years moderate to severe deficits occurred in 5%. Language deficits may emerge over time, warranting close follow-up.

Project description:Background and Purpose: Hyperhomocysteinemia (Hhcy) is a well-known risk factor for ischemic stroke. However, the role of Hhcy in the clinical outcome of ischemic stroke has not been fully elucidated. In addition, previous studies have found that Hhcy was implicated in the disruption of the blood-brain barrier, which may increase the risk of hemorrhagic transformation (HT) after thrombolysis. Thus, the aim of this study was to investigate the effect of Hhcy on the clinical outcome and HT after thrombolysis in ischemic stroke patients. Methods: Patients who were diagnosed with ischemic stroke and received intravenous thrombolytic therapy between January 2016 and September 2018 were included in this study. Multivariate logistic regression analysis was used to assess the association between Hhcy, clinical outcome, and HT after thrombolysis. Furthermore, the potential interaction between Hhcy and hypertension on the clinical outcome and HT after thrombolysis was also assessed. Results: Of 568 patients, 455 (80.1%) had Hhcy, 66 (11.6%) had HT, and 219 (38.6%) had poor outcome. Patients with Hhcy had a higher incidence of poor outcome than the patients with non-Hhcy (40.9 vs. 29.2%, p = 0.022). However, there was no significant difference in the incidence of HT (11.9 vs. 10.6%, p = 0.711) between patients with Hhcy and non-Hhcy. After adjustment for major covariates, multivariate logistic regression analysis disclosed that Hhcy was independently associated with increased risk of poor outcome (OR = 1.760; 95% CI: 1.069-2.896) but was not associated with the risk of HT (OR = 1.017; 95% CI: 0.495-2.087). In addition, we found no significant interaction between Hhcy and hypertension on the clinical outcome (p = 0.513) or HT (p = 0.170) after thrombolysis. Conclusion: We found that Hhcy was an independent risk factor for poor outcome, but not an independent risk factor for HT after thrombolysis in ischemic stroke patients. In addition, there was no significant interaction of Hhcy and hypertension on the clinical outcome or HT after thrombolysis.
