Clinical characteristics of antiNmethylaspartate receptor encephalitis in children / 中南大学学报(医学版)

OBJECTIVES@#To analyze the clinical characteristics and prognosis of children with anti-N-methyl--aspartate receptor (NMDAR) encephalitis and to provide a basis for early clinical identification of this disease.@*METHODS@#The clinical data of 42 cases of anti-NMDAR encephalitis at Department of Pediatrics, Second Xiangya Hospital, Central South University from January 2015 to March 2018 were collected. The clinical features and followed-up outcomes were analyzed retrospectively.@*RESULTS@#There were 15 cases (35.7%) of males and 27 cases (64.3%) of females in 42 children, with a ratio of 1꞉1.8. They were aged from 4 months to 17 years, with an average of (9.20±4.66) years. The most common initial symptoms were seizures (47.6%, 20/42) and mental behavior disorder (35.7%, 15/42). During the course of the disease, 85.7% patients(36/42) had mental and behavior disorder, 85.7% patients (36/42) had epilepsy, 76.2% (32/42) had speech disorder, 66.7% patients (28/42) had dyskinesia, 66.7% patients (28/42) had the decreased level of consciousness, 61.9% patients (26/42) had autonomic instability, and 57.1% (24/42) patients had sleep disorder. All the children had positive antibody against NMDA receptor resistance encephalitis in cerebrospinal fluid. Head MRI showed the abnormal incidence was 50.0% (21/42), and the lesions involved in parietal lobe, frontal lobe, temporal lobe, occipital lobe, midbrain, thalamus, basal ganglia and optic nerve. There was a patient with optic nerve damage combined with myelin oligodendrocyte glycoprotein (MOG) antibody positive. Forty cases were examined by electroencephalogram (EEG), 92.5% cases (37/40) were abnormal, mainly showing diffuse slow waves, and δ brushes could be seen in severe cases. And there was 1 patient (2.4%) complicated with mesenteric teratoma. The mRS score (2.14±1.46) at discharge was significantly lower than the highest mRS score (3.88±1.38) during hospitalization (<0.05). After 3-39 months of follow-up, mRS score at 3 months after discharge was only 0.81±1.29, which was still improved compared with that at discharge, 76.2% cases (32/42) experienced complete or near-complete recovery (mRS score≤2), and 4.8% (2/42) cases relapsed. There was no mortality; the initial time of immunotherapy and the highest mRS score in the course of the disease were the factors affecting the prognosis. The earlier the starting time for immunotherapy and the lower mRS score in the course of the disease were, the better the prognosis was.@*CONCLUSIONS@#Seizures, mental and behavior disorder, dyskinesias, speech disorder and autonomic instability are common clinical manifestations of anti-NMDAR encephalitis in children. The effect of immunotherapy is significant, and the time to start immunotherapy and the severity of the disease are important factors affecting the prognosis. Anti-NMDAR encephalitis can be combined with other autoantibodies, but its clinical significance and mechanism need further study.

Analysis of the Risk Factors for Hypertension in Patients with Chronic Kidney Disease Stage 5 / 华中科技大学学报(医学版)

Objective To analyze the risk factors for hypertension in patients with chronic kidney disease stage 5(CKD5) . Methods The basic information of 390 CKD5 patients complicated with hypertension was collected for univariate analysis ,in‐cluding gender ,age ,primary disease ,dialysis method ,body mass index(BMI) ,complications(hyperlipidemia ,high uric acid ,car‐diac insufficiency) ,level of education ,parathyroid hormone(PTH)level.Univariate variables that showed statistical significance were then subjected to the multivariate analysis(Logistic regression)to identify the risk factors for hypertension in CKD5 pa‐tients.The defined daily dose(DDD)that satisfied the criteria interms of different stages was evaluated.Results Overall hyper‐tension control rate was 22.8%.Univariate analysis showed that the following variables were significantly associated with hy‐pertension in CKD5 patients :>40 years old ,male ,diabetic nephropathy ,hypertensive nephropathy ,hemodialysis ,hyperlipemia , high uric acid level ,and high PTH level(P0.05) ,and DDD at stage 2 and 3 was increased signifi‐cantly when compared with that at 0 and 1 standard(P<0.05).Conclusion Overall hypertension control rate is very low in pa‐tients with CKD5.Diabetics ,hyperlipidemia ,high PTH level are independent risk factors for hypertension in patients with CKD5.

Syncope and epilepsy / 中华实用儿科临床杂志

Syncope and epilepsy are common pediatric clinical symptoms and causes of paroxysmal loss of consciousness.They can be manifested as a sudden attack,transient and reversible loss of consciousness,easily leading to misdiagnosis in clinics.The etiology and pathogenesis of syncope and epilepsy are completely different,and the principle of treatment is also different.Therefore,in clinics,making an early diagnosis and differential diagnosis between syncope and epilepsy has an important significance to improve the treatment and the prognosis of the patients.
