Postencephalitic epilepsy in dogs with meningoencephalitis of unknown origin: Clinical features, risk factors, and long-term outcome.

ABSTRACT:

Background

Although the presence of seizures in dogs with meningoencephalitis of unknown origin (MUO) has been associated with shorter survival times, data regarding the prevalence and risk factors for postencephalitic epilepsy (PEE) is lacking.

Objectives

To describe the clinical features, prevalence, risk factors, and long-term outcome of PEE in dogs with MUO.

Animals

Sixty-one dogs with presumptive diagnosis of MUO based on the clinicopathological and diagnostic imaging findings.

Methods

Retrospective study. Cases were identified by search of hospital medical records for dogs with suspected or confirmed MUO. Medical records of dogs meeting inclusion criteria were reviewed. Signalment, seizure history, clinicopathologic, and magnetic resonance imaging (MRI) findings were recorded.

Results

Among 61 dogs at risk of PEE, 14 (23%) dogs developed PEE. Three of 14 dogs with PEE (21%) developed drug-resistant epilepsy. Dogs with PEE were younger (P = .03; OR_adjusted = 0.75; 95% confidence interval [CI], 0.58-0.98) and had significantly shorter survival times (log-rank test P = .04) when compared to dogs that did not develop epilepsy. The risk factors associated with the development of PEE were the presence of acute symptomatic seizures (ASS; P = .04; OR_adjusted = 4.76; 95% CI, 1.11-20.4) and MRI lesions in the hippocampus (P = .04; OR_adjusted = 4.75; 95% CI, 1.07-21.0).

Conclusions and clinical importance

Dogs with MUO and seizures at the early stage of the disease (ASS) seem to be at a higher risk of developing PEE.

Project description:Since prediction of long-term seizure outcome using preoperative diagnostic modalities remains suboptimal in epilepsy surgery, we evaluated whether interictal spike frequency measures obtained from extraoperative subdural electrocorticography (ECoG) recording could predict long-term seizure outcome. This study included 61 young patients (age 0.4-23.0 years), who underwent extraoperative ECoG recording prior to cortical resection for alleviation of uncontrolled focal seizures. Patient age, frequency of preoperative seizures, neuroimaging findings, ictal and interictal ECoG measures were preoperatively obtained. The seizure outcome was prospectively measured [follow-up period: 2.5-6.4 years (mean 4.6 years)]. Univariate and multivariate logistic regression analyses determined how well preoperative demographic and diagnostic measures predicted long-term seizure outcome. Following the initial cortical resection, Engel Class I, II, III and IV outcomes were noted in 35, 6, 12 and 7 patients, respectively. One child died due to disseminated intravascular coagulation associated with pseudomonas sepsis 2 days after surgery. Univariate regression analyses revealed that incomplete removal of seizure onset zone, higher interictal spike-frequency in the preserved cortex and incomplete removal of cortical abnormalities on neuroimaging were associated with a greater risk of failing to obtain Class I outcome. Multivariate logistic regression analysis revealed that incomplete removal of seizure onset zone was the only independent predictor of failure to obtain Class I outcome. The goodness of regression model fit and the predictive ability of regression model were greatest in the full regression model incorporating both ictal and interictal measures [R(2) 0.44; Area under the receiver operating characteristic (ROC) curve: 0.81], slightly smaller in the reduced model incorporating ictal but not interictal measures (R(2) 0.40; Area under the ROC curve: 0.79) and slightly smaller again in the reduced model incorporating interictal but not ictal measures (R(2) 0.27; Area under the ROC curve: 0.77). Seizure onset zone and interictal spike frequency measures on subdural ECoG recording may both be useful in predicting the long-term seizure outcome of epilepsy surgery. Yet, the additive clinical impact of interictal spike frequency measures to predict long-term surgical outcome may be modest in the presence of ictal ECoG and neuroimaging data.

Project description:Although male predominance was documented in previous studies on cryptococcal meningoencephalitis (CM), there has been no statistical study about female CM patients despite recently noticeable increase in female prevalence. In the current study, we aimed to investigate the independent gender-specific contributing risk factors for onset of CM and factors related to survival time in female patients by chosen statistical tools.There have been 108 patients diagnosed with CM from July 1, 1998 to June 30, 2013 in Nanfang Hospital that were included in our study. This 15-year retrospective study compared demographic and clinical features of 31 female patients with 77 males. Multivariate analysis was performed for detection of the contributors to the onset of CM in female patients. The independent variables for multivariate analysis were selected according to statistical significance in univariate analysis. Furthermore, Cox regression model was used to evaluate the factors related to survival length.Use of corticosteroids or other immunosuppressants (32.3% versus 11.7%; p = 0.011) and history of systemic lupus erythematosus (SLE) and other autoimmune diseases (29% versus 3.9%; p < 0.001) were more common in females, but only the history of SLE or other autoimmune diseases was significant (OR 10.59, 95% CI 1.49-74.77, p = 0.02) by multivariate analysis. The ratio of cerebrospinal fluid (CSF) glucose-to-blood glucose was related to the survival time (p = 0.03, 95% CI 0-0.71).The results showed that the history of SLE or other autoimmune diseases rather than chronic use of corticosteroids and/or immunosuppressants was the independent gender-specific contributing risk factor in female CM patients. Therefore, more attention should be made to the prevention of infection from the genus Cryptococcus spp. in female patients with SLE or other autoimmune diseases. In addition, decreased ratio of CSF glucose-to-blood glucose before antifungal therapy predicted the worse prognosis.
