Abstract:
Objective:To analyze the prognosis and influencing factors of acute necrotizing encephalopathy (ANE) in children.Methods:Clinical data of ANE patients admitted to Pediatric Intensive Care Unit, Beijing Children′s Hospital, Capital Medical University from March 2012 to February 2019 were retrospectively analyzed.Survivors were followed up by telephone or outpatient department, and the quality of life was evaluated by pediatric overall performance category scale.The t-test or rank sum test was used for comparison between groups, and the COX risk regression was used to analyze the influencing factors of prognosis. Results:A total of 38 patients were enrolled in this study with the male-to-female ratio of 1.24∶1.00, and median age of 29.5(10.0-130.0) months.They were followed up for the median of 27(15-96) months.The overall survival rate at 7 days, 14 days and 2 months after disease onset were 57.9%, 42.1%, and 34.2%, respectively.The mortality rate at discharge was 34.2%(13/38 cases), and the cumulative mortality rate at the 1 st, 3 rd and 12 th months after discharge was all 68.4%(26/38 cases). The complete reco-very rate was 10.5%(4/38 cases) after one-year follow-up.The univariate analysis indicated that cardiopulmonary resuscitation before admission, Glasgow coma score < 5 at admission, complication with shock/cerebral hernia/multiple organ dysfunction syndrome, creatine kinase isoenzyme> 100 U/L, lactate dehydrogenase>1 000 U/L, hypoalbuminemia, hyperglycemia, hyperurea, prolonged prothrombin time and elevated international standardized ratio were risk factors for the prognosis of ANE in children ( β=3.519, 6.967, 6.803, 3.000, 6.389, 3.471, 2.252, 1.616, 2.377, 3.092, 2.713, and 4.510, respectively, all P<0.05). Meanwhile, high-dose Methylprednisolone[20-30 mg/(kg·d)] and immunoglobulin (2 g/kg, divided into 2-5 days intravenous drip) treatment were protective factors ( β=0.625, 0.405, respectively, all P<0.05). The COX multivariate analysis showed that high-dose Methylprednisolone treatment [20-30 mg/(kg·d)] was an independent protective factor for the prognosis of children with ANE [95% CI: 0.449(0.213-0.944), P=0.035]. Conclusions:Early application of high-dose Methylprednisolone and immunoglobulin may contribute to the good clinical outcome.Children with neurological sequelae should be actively treated with rehabilitation, and the quality of life may be gradually improved.
