Clinico-Etiological Profile of Pediatric Refractory Status Epilepticus at a Public Hospital in India

Reducing epilepsy diagnostic and treatment gaps: Standardized paediatric epilepsy training courses for health care professionals

AIM

To evaluate improvement in knowledge and clinical behaviour among healthcare professionals after attendance at paediatric epilepsy training (PET) courses.

METHOD

Since 2005, 1-day PET courses have taught evidence-based paediatric epilepsy management to doctors and nurses in low-, middle-, and high-income countries. A cohort study was performed of 7528 participants attending 252 1-day PET courses between 2005 and 2020 in 17 low-, middle-, and high-income countries, and which gathered data from participants immediately after the course and then 6 months later. Training outcomes were measured prospectively in three domains (reaction, learning, and behaviour) using a mixed-methods approach involving a feedback questionnaire, a knowledge quiz before and after the course, and a 6-month survey.

RESULTS

Ninety-eight per cent (7217 of 7395) of participants rated the course as excellent or good. Participants demonstrated knowledge gain, answering a significantly higher proportion of questions correctly after the course compared to before the course (88% [47 883 of 54 196], correct answers/all quiz answers, vs 75% [40 424 of 54 196]; p < 0.001). Most survey responders reported that the course had improved their epilepsy diagnosis and management (73% [311 of 425]), clinical service (68% [290 of 427]), and local epilepsy training (68% [290 of 427]).

INTERPRETATION

This was the largest evaluation of a global epilepsy training course. Participants reported high course satisfaction, showed knowledge gain, and described improvements in clinical behaviour 6 months later. PET supports the global reduction in the epilepsy 'treatment gap' as promoted by the World Health Organization.

Hospital-Based Prevalence, Electroencephalogram (EEG), and Neuroimaging Correlation in Seizures Among Children in Odisha, India

Background: Febrile seizures are very common in pediatric practice. We need to differentiate between febrile seizures and other seizures due to central nervous system (CNS) infection by various means of investigation. Though approximately 30% of patients with febrile seizure have later epilepsy and the risk is around 20% even if electroencephalogram (EEG), and neuro-imagings are normal. But data regarding this is laking in developing countries like India.

Aim: The primary objective of this study is to determine the hospital-based prevalence among various types and etiologies of seizures in children admitted to the pediatric department in a teaching hospital of a developing country, India. Besides, the different types of seizures were correlated with the EEG and neuroimaging findings along with the acute onset of seizures among children.

Methods: In this prospective observational study, children from two months to 15 years of age admitted to the Pediatrics Department, KIMS, Bhubaneswar in India between September 2017 and September 2019 were taken. The patients having seizures were included in the study based on the inclusion criteria. Neurological and systemic examinations of the children were recorded and the neuroimaging reports were analyzed.

Results: A total of 19,553 patients aged two months to 15 years were admitted during the study period. Of that, 1,192 cases were diagnosed with febrile and unprovoked seizures. It was observed that the hospital-based prevalence of seizures among children in Odisha was 6%. Besides, it is found that generalized seizure disorder was the most common among the children. It was found that abnormal EEG, magnetic resonance imaging (MRI), and computed tomography (CT) brain in 60% (202/340), 49% (113/230), and 47% (136/288) of cases, respectively. MRI is a better modality of investigation in partial seizure cases 22 (64%) to detect CNS abnormality. Also, MRI of the brain is better in evaluating CNS abnormality in complex febrile cases 4 (31%) than CT brain (0%).

Conclusion: The study concluded that EEG must be the standard modality of test for patients' diagnosis of seizure in children with seizures. CT/MRI scan can give a better supplement to the results but MRI findings are more accurate in cases of complex febrile seizures.

Utility of the END-IT Score to Predict the outcome of Childhood Status Epilepticus: A Retrospective Cohort Study

Introduction:

Scoring systems to predict outcomes in pediatric status epilepticus (SE) are limited. We sought to assess usefulness of the END-IT score in pediatric SE.

Methodology:

We conducted a retrospective study at a tertiary hospital in New Delhi, India. Children aged 1 month–18 years who presented with seizure for ≥5 min/actively convulsing to emergency were enrolled. END-IT score was calculated and correlated with outcome at discharge using Pediatric Overall Performance Category (POPC) scale, in-hospital mortality, and progression to refractory and super-refractory SE (SRSE).

Results:

We enrolled 140 children (mean age 5.8 years; 67.1% males). Seven children died and 15 had unfavorable outcomes. The predictive accuracy of END-IT at a cutoff of > 2: for unfavorable outcome (POPC score ≥3) was: sensitivity 0.73 (95% CI: 0.45–0.92), specificity 0.94 (95% CI: 0.89–0.98), PPV 0.61 (95% CI: 0.36–0.83), NPV 0.97 (95% CI: 0.92–0.99), positive likelihood ratio (13.09), F1 score (0.666); for death: sensitivity 0.86 (95% CI: 0.42–0.99), specificity 0.91 (95% CI: 0.85–0.95), PPV 0.33 (95% CI: 0.13–0.59), NPV 0.99 (95% CI: 0.96–1.00), F1 score (0.48); for RSE: sensitivity 0.80 (95%CI: 0.28–0.99), specificity 0.90 (95% CI: 0.83–0.94), PPV 0.22 (95% CI: 0.06–0.48) NPV 0.99 (95% CI: 0.96–1.00), F1 score (0.35); for SRSE: sensitivity 0.67 (95% CI: 0.22–0.96) specificity 0.75 (95% CI: 0.66–0.82), PPV 0.22 (95% CI: 0.06–0.48) NPV 0.98 (95% CI: 0.94–0.99), F1 score (0.33).

Conclusion:

We demonstrate utility of the END-IT score to predict short-term outcomes as well as progression to refractory and SRSE for the first time among children with SE.

Clinical Feature and Outcome of Childhood Status Epilepticus in a Teaching Hospital, Odisha, India

Objectives

The main aim is to find out the clinical feature and outcome of status epilepticus (SE) in children managed in a teaching hospital. The secondary aim is to identify the risk factors influencing the adverse outcomes.

Methods

In this prospective cohort, children aged 1 month to 14 years with SE as per the International League Against Epilepsy’s new guideline (2016) who presented to the emergency department during the period of November 2017 to October 2019 were enrolled. Clinical profile, treatment, and outcome of cases (n = 94) were noted.

Results

The majority of children, 60 (63.82%), were less than five years of age. Prior history of seizures was present in 33 (35.1%) cases, whereas 61 (64.9%) cases presented with SE as the first episode of seizure. In 14 (42.4%) previous seizure cases, SE was due to drug default. No response to first-line antiepileptic drug (AED) was seen in 84 (89.37%) cases. Acute symptomatic etiology was the commonest etiology of SE in 64 (68%) cases, of which neuro-infections accounted for 44 (46.80%) cases. Longer duration (>60 minutes) of status (p < 0.01), ventilator support (p < 0.0001), and circulatory impairment (p < 0.0001) were attributable risk factors for mortality. A total of 28 children died (mortality rate, 29.8%), and 11 showed the persistence of their neuro-deficit.

Conclusions

Neuro-infection is the most common etiology of SE in children. Longer duration of SE, more lag time for receiving the first AED, respiratory failure, and presence of shock are independent predictors for poor outcome. Hence, cessation of convulsion at the earliest leads to improved outcomes.
