Risk factors for suicidal tendency in people with epilepsy in China: a case-control study.

People with epilepsy (PWE) have an increased suicide prevalence. This study aimed to identify the risk factors for suicidal tendency among PWE in West China. A nested case-control study was designed in a cohort of patients with epilepsy (n = 2087). In total, 28 variates were calculated. In the univariate analysis, unemployment, low income, seizure frequency, seizure-free time, infectious or structural etiology, levetiracetam or phenobarbital use, anxiety, depression, and stigma were associated with suicidal tendency. A multivariate analysis indicated that unemployment (odds ratio [OR] 5.74, 95% confidence interval [CI] 2.13-15.48), levetiracetam use (OR 2.80, 95%CI 1.11-7.05), depression (C-NDDI-E score ≥ 13; OR 3.21, 95%CI 1.26-8.21), and stigma (SSCI score ≥ 16; OR 6.67, 95%CI 1.80-24.69) were independently associated with suicidal tendency. Conditional inference tree analysis indicated that SSCI and C-NDDI-E scores could effectively identify patients with suicidal tendency. Thus, this study suggests that unemployment, levetiracetam use, depression, and stigma are independent risk factors for suicidal tendency in PWE in China.

Hydrocephalus in Guillain barre syndrome: A case report and review of the literature.

RATIONALE: Guillian-Barré syndrome (GBS) is a devastating autoimmune disorder characterized by progressive ascending weakness, areflexia with or without autonomic and sensory disturbances. Hydrocephalus is a rare but well-documented complication in patients with GBS. However, due to the rarity of this condition, no treatment guideline for GBS with hydrocephalus is currently available. PATIENT CONCERNS: We describe a 23-year old woman with a history of bilateral limbs pain followed by dysarthria, dysphagia, severe quadriplegia 0/5, areflexia, loss of consciousness and dysautonomia. Neuroimaging studies revealed enlarged lateral ventricles; while Electromyography demonstrated demyelination and nerve injury. Lumbar puncture results showed elevated protein level 2.6 g/L; normal glucose and cell count. DIAGNOSIS: GBS with hydrocephalus. INTERVENTIONS: The patient was started on intravenous immunoglobulin for 5 consecutive days followed by endotracheal intubation and supportive therapy including osmotherapy and CSF drainage. OUTCOMES: At 2 months after admission, the patient stopped choking and had a significant improvement in muscles' strength (grade 4) and pain; then was discharged. On 1 year post-discharge follow-up, CT has revealed a significant improvement of hydrocephalus, and the patient has completely returned to the normal baseline. LESSONS: Respiratory failure is the strongest predictor of concurrent hydrocephalus in patients with GBS. The prognosis of hydrocephalus in patients with GBS is usually good, and it can be medically treated; thereby shunt surgery is rarely required.

Clinical Features, Radiological Characteristics, and Outcomes of Patients With Intracranial Alveolar Echinococcosis: A Case Series From Tibetan Areas of Sichuan Province, China.

Objectives: Intracranial alveolar echinococcosis (IAE), a zoonotic disease, is a critical health problem in the Tibetan region. We aimed to describe the clinical and radiological characteristics and outcomes among patients with IAE. Methods: We screened patients diagnosed with IAE between March 2015 and May 2019 at the Ganzi Tibetan Autonomous Prefecture People's Hospital. Detailed demographics, clinical characteristics, neuroimaging features, and outcomes were recorded. Results: A total of 21 patients with an average age of 44.1 ± 12.7 years were included. Thirteen (61.9%) patients were male. The most common chief neurological complaint was headache (n = 17, 81.0%), followed by dizziness, seizure, visual disturbances, hemiparesis, disturbed consciousness, and dysphasia. All the patients had coexisting liver localizations. The typical neuroimaging features of IAE on cerebral magnetic resonance imaging scans showed obvious low-signal shadow with multiple small vesicles inside the lesions on T2-weighted images and FLAIR images. The pathological HE staining demonstrates vesicular lesions with several internal sacs. For hepatic alveolar echinococcosis (AE), the hepatic portal was invaded in six (28.6%) patients, and the portal vein (n = 5, 23.8%) was the mostly commonly involved vessel. As for treatment, 11 patients (52.4%) had poor compliance with albendazole. The duration of patients taken albendazole ranged from 2 months to 3 years. Cerebral AE surgery was performed in 11 patients, five of them underwent partial resection of AE lesions, and six patients received total resection. One patient with primary IAE underwent radical surgery. Ten patients (47.6%) died during the follow-up for a mean of 21.7 ± 11.9 (3-46) months. In total, 28.9% of the patients died within 5 years, and 71.6% died within 10 years. The median interval between the date of diagnosis as AE and death was 84 (19-144) months. Conclusion: Despite substantial advances in diagnostic and therapeutic methods, the treatment of IAE remains difficult and results in unsatisfactory outcomes. The major critical issue is surgical treatment of IAE although the disease is disseminated. Besides, lifelong albendazole would be indicated, but most patients had poor medication compliance. It is important to educate patients about the necessity of medical treatment.

Epilepsy in China: Factors influencing marriage status and fertility.

PURPOSE: To investigate the current status of marriage and fertility of patients with epilepsy (PWE) and characterize its influencing factors. METHODS: A total of 1,823 adult patients (males age 22 years or older, females age 20 years or older) were included in this study. Data concerning sociodemographic and clinical characteristics were collected. Descriptive analyses, followed by univariate and multivariate logistic regression analyses were utilized to examine factors associated with marriage and fertility of PWE. Marital status of PWE was compared with Chinese population. Standardized marriage rate (SMR) for age and sex was estimated based on the 2010 sixth national population census. RESULTS: 1,132 patients (62.1%) were married and 823 (45.1%) had a history of fertility. Patients had lower marriage rates than Chinese population (62.1% vs 78.4%). Patients with adult-onset epilepsy (>18 years) had a significantly higher rate of marriage and fertility (p ＜ 0.001) compared to those with childhood-onset epilepsy (≤18 years). Employed patients had higher marriage rates than unemployed patients (64.9% vs 58.6%, p = 0.006), with only male patients being significantly affected by employment status (p ＜ 0.001). Multiple logistic regression revealed that age, age at first seizure onset, and employment status were related to both marriage and fertility. CONCLUSION: Epilepsy had negative effects on marriage and fertility status. Marriage and fertility rates were lower in patients with Childhood-onset epilepsy (≤18 years). Furthermore, employment status mainly affected the marriage rate of male patients.

Comparison of Standard and Intensified Regimens for HIV-Negative Adults With Tuberculous Meningitis in West China: A Retrospective Observational Study.

Background: Tuberculous meningitis (TBM) is an extremely devastating inflammation of the central nervous system; however, no available optimum treatment can effectively control the disease so far. Method: The medical records of TBM patients from May 2011 to August 2016 in West China hospital were retrospectively analyzed. Patients were divided into three groups based on their treatment regimens {Group1: 4 standard therapy; Group2: 3 standard drugs + Levofloxacin; Group3: 4 standard therapy + Levofloxacin (G3a)/ Moxifloxacin (G3b)}. Using the intention-to-treat analysis, eventually, the treatments' efficacy and safety were compared among all groups. Results: Two hundred two patients with TBM were enrolled and followed up for at least 2 years. Among them, 99 patients were in G1; 18 in G2; and 85 in G3 (Moxifloxacin=39/ Levofloxacin=49). One hundred fifteen (56.9%) patients were males, and the median age was 42 years. At admission, 74 patients (36.6%) were in stage I, 102 (50.5%) in stage II and 26 (12.9%) in stage III. The most common symptoms were headache in 194 (96.0%) patients, fever in 162 (80.2%), vomiting in 120 (59.7%), neck stiffness in 104 (51.5%), and malaise in 96 (47.5%). The overall outcome at 1 year showed that 47 patients (47.5%) in G1, 10 patients (55.6%) in G2 and 48 patients (56.5%) in G3 had good outcome; however, there was no significant difference among all groups (P = 0.397); at 2 years there was also no difference among treatment groups (P = 0.295). However, in Group3b 22 patients (56.4%) at 1-year and 26 (66.7%) at 2-year follow up had a full recovery, which is significantly superior to other treatment groups, the P value at 1 and 2 years was 0.002 and 0.027, respectively. Conclusion: The overall outcome in patients with TBM at 1 and 2 years follow up did not show any statistically significant difference between the standard chemotherapy and other intensified regimens. Furthermore, Hydrocephalus (OR = 3.461, 95% CI: 1.349-8.882, P = 0.010) was the only independent risk factor for a poor outcome.

Factors associated with seizure-related motor vehicle accidents among patients with epilepsy in West China.

PURPOSE: This study was conducted to investigate the relevant demographics and clinical factors contributing to seizure-related motor vehicle accidents in west China. METHODS: All driving patients who visited our epilepsy clinic in the West China Hospital, between October 2012 and October 2016, were invited to participate. Data on social demographics, clinical features, and motor vehicle accidents were collected during structured interviews. Binary logistic regression was used to identify factors associated with seizure-related motor vehicle accidents. RESULTS: In total, 519 patients reported driving after being diagnosed with epilepsy. Among them, thirty-nine (7.5%) patients experienced at least one seizure-related motor vehicle accidents. Patients who had seizure-free intervals ≥2 years had a 89% reduced chance of crashing compared to patients with shorter intervals. Logistic regression revealed that the interval of seizure freedom (B = -0.384, P = 0.007), number of antiepileptic drugs (AEDs) taken (B = 0.400, P = 0.041), and type of motor vehicle (B = 0.798, P = 0.021) were independently associated with seizure-related motor vehicle accidents. CONCLUSION: The interval of seizure freedom, number of AEDs taken, and type of motor vehicle should be considered when counseling patients with epilepsy on driving. A longer seizure-free interval suggested a compromised risk of seizure-related motor vehicle accidents.

Paraneoplastic cerebellar degeneration associated with cerebellar hypermetabolism: Case report.

RATIONALE: Paraneoplastic cerebellar degeneration (PCD) is an immune-mediated neurological deficit affecting the cerebellum. Anti-Yo antibody positive PCD is a rare occurrence most likely associated with gynecologic or breast malignancies. The identification of the underlying tumor is a diagnostic challenge in many of these patients. PATIENT CONCERNS: We present a 68-year-old woman with acute symptoms of PCD as a first sign of underlying occult malignancy. Further investigation revealed a positive anti-Yo antibody. Although brain magnetic resonance imaging (MRI) was unremarkable, positron emission tomography (PET)/computed tomography (CT) revealed intense hypermetabolism of cerebellum and diffused hypometabolism in the rest of brain. On 1-year follow-up, despite the primary malignancy is still unknown, her symptoms improved significantly after immunotherapy. DIAGNOSES: Paraneoplastic cerebellar degeneration. INTERVENTIONS: The patient was given IV methylprednisolone 500 mg once a day for 5 consecutive days, followed by oral prednisone 60 mg once a day for 3 months. OUTCOMES: The patient's symptoms were gradually improved during the hospitalization period. On one year follow up, she was able to walk independently and perform some simple tasks. LESSONS: Cerebellar hypermetabolism in PCD suspected patients may help confirming the diagnosis in an earlier stage and may predict a better outcome after immunotherapy.

Allergy in patients with anti-N-methyl-d-aspartate receptor encephalitis.

BACKGROUND AND OBJECTIVE: Allergy is a potential outcome of dysregulated immune system. Previous studies have shown the association of allergy and autoimmune diseases, however, there is few study to investigate the relationship between allergy and anti-N-methyl-d-aspartate receptor (anti-NMDAR) encephalitis. Thus, we investigate the rate of allergy in patients with anti-NMDAR encephalitis and analyze the risk factors. METHOD: The rate of allergy was investigated in patients with anti-NMDAR encephalitis and was compared with patients with virus encephalitis. The clinical cutaneous characters were described in details. All patients with anti-NMDAR encephalitis were divided into allergic and nonallergic group. Clinical factors were compared in the two groups, and logistic regression model was also used to analyze possible risk factors of allergy. RESULTS: Patients with anti-NMDAR encephalitis had a higher rate of allergy than those with viral encephalitis (22.1% vs 9.2%, odds ratio (OR)=3.23, confidence interval (CI)=1.40-7.42, P=0.006). In patients with anti-NMDAR encephalitis, allergic patients exhibited longer days in hospital (30days vs 22days, P=0.005) and higher occurrence of decreased consciousness (81.5% vs 58.9%, P=0.031), higher rate of complications (77.8% vs 57.9%, P=0.046) and abnormal electroencephalography (EEG) (100% vs 78.6%, P=0.021) than patients without allergy. Cerebrospinal fluid (CSF) antibody titers of allergic patients during the disease course were also higher than nonallergic patients (P=0.004). However, further logistic regression analysis did not reveal independent predictors of allergy. CONCLUSIONS: Patients with anti-NMDAR encephalitis show higher allergic rate than those with virus encephalitis. Patients with allergy show higher CSF antibody titers and greater illness severity. However, the final outcome of anti-NMDAR encephalitis was not influenced.

Suicidality is a common and serious feature of anti-N-methyl-D-aspartate receptor encephalitis.

We aimed to assess suicidality risk amongst people who had had anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis. All people with a definitive diagnosis of anti-NMDAR encephalitis in West China Hospital between June 2012 and February 2017 were identified and their notes were retrospectively reviewed. Demographic and clinical characteristics and risk predictors for suicidality were summarized; those with suicidality were compared to those without. 17 of 133 people (13%) presented with suicidality symptoms: 7 (5%) with suicidal ideation; 8 (6%) who attempted suicide; and 2 (1.5%) who completed suicide. Median age was 27 (16-78) years, most were female [13 (76%)]. Compared with those with no suicidality, psychiatric symptoms as the initial symptoms were more frequent in those who reported suicidality (p = 0.039); insomnia, aggression, mania, depression and delusion were also more common (p < 0.05). The use of antidepressants (p < 0.001) and recurrence of encephalitis (p = 0.020) were higher in people with suicidality than in those without. Other characteristics were not significantly different in those who had suicidality and those who did not. Suicidality is a common and potentially lethal risk for people with anti-NMDAR encephalitis. Those presenting with psychiatric symptoms as the initial symptom and with insomnia, aggression, mania, depression and delusion should be carefully screened for suicidality. Closely monitoring people who have been treated with antidepressants is necessary.
