Clinical Trial Summary

The National Registry of Epilepsy in Mexico aims to be an observational, multicenter, and nationwide study about Epilepsy in Mexico. This project is proposed as the first registry about the diagnosis and treatment of epilepsy in Mexico. The participation of major health institutions, both public and private, of each state to ensure that the registry is representative of the country is planned.

Clinical Trial Description

Introduction Epilepsy is a brain chronic condition characterized by the recurrence of unprovoked motor and non-motor seizures. A seizure can be defined as the transient appearance of signs and/or symptoms due to excessive abnormal neuronal activity in the brain.

The International League against Epilepsy (ILAE) proposes that epilepsy should be considered a brain disease based on at least one of the following conditions: (1) at least two unprovoked (or reflex) seizures occurring more than 24 hours apart; (2) one unprovoked (or reflex) seizure and a probability of further seizures similar to the general recurrence risk (at least 60%) after two unprovoked seizures, occurring over the next ten years; (3) diagnosis of an epilepsy syndrome.

Epilepsy is one of the most common neurological diseases worldwide, affecting around 60 million people of all ages around the world. The risk of premature death in people with epilepsy is up to three times that of the general population. The lives of people with epilepsy are often impacted by stigma, discrimination, and human rights violations.

Nearly 80% of people with epilepsy live in low- and middle-income countries (LMIC), where treatment gaps exceed 75% in most low-income countries and 50% in most middle-income countries. Unfortunately, the lack of epidemiological registries about this disease makes early diagnosis and effective treatment difficult, thus increasing its prevalence.

Design and methods The National Registry of Epilepsy in Mexico aims to be an observational, multicenter, and nationwide study about Epilepsy in Mexico. This project is proposed as the first registry about the diagnosis and treatment of epilepsy in Mexico. The participation of major health institutions, both public and private, of each state to ensure that the registry is representative of the country is planned. It seeks for wide geographical distribution to compare the quality of care between the different geographical areas of the country.

Data will be registered in an electronic case report form (CRF) stored in a centralized database in which all the necessary data for the study will be included. The study variables will be (1) demographic, (2) from diagnosis and its clinical manifestations, (3) results of laboratory tests and cabinet examinations, (4) treatment, previous and current, (5) clinical variables of concomitant diseases and factors that trigger or precipitate seizures, (6) frequency and number of seizures, and (7) type of medical care. Data collection will be performed from the usual clinical practice through the participating researchers themselves, the patient's medical history at the time of inclusion in the study, and data from the patients through a mobile app during the follow-up period, developed following updated information from the Clinical Guidelines of the Epilepsy Priority Program published in 20194 which are adhered to the current concepts of ILAE.

Demographic and clinical data will be obtained (focal or generalized, motor or non-motor seizures) and the general medical condition of the patient will be evaluated as stated in the Clinical Guideline of the Epilepsy Priority Program4 from the usual clinical visits and during the 6-month follow-up. According to the incidence of epilepsy reported worldwide and considering the Mexican population treated in the participating hospitals, the inclusion of at least 15,000 patients is estimated.

Objectives To know the current status of the diagnosis and treatment of epilepsy in Mexico in order to identify the clinical characteristics, treatment trends, and evolution during the 6-month follow-up, as well as the adherence to current clinical practice guidelines.

Inclusion and exclusion criteria Candidates for the registry are those patients of any gender, older and any age who present an Epilepsy diagnosis according to the current definition of the ILAE 2014.

Sites The Epilepsy Comprehensive Care Centers (CAIE), members of the Epilepsy Priority Program (PPE) of the Healthcare Sector in Mexico will participate, all with knowledge and experience in the diagnosis and treatment of patients with epilepsy.

Data analysis Descriptive and differential statistics will be used according to the observation obtained. For continuous variables, mean, standard deviation (SD), standard error of the mean (SEM), 95% confidence interval (CI 95%) minimum, percentile 25 (P25), median or percentile 50 (P50), percentile 75 (P75) and maximum, number of patients (n) and number of lost data will be obtained as descriptive statistics. For categorical variables, % will be obtained from the total and number of patients (n) in each category. Lost data will be treated as a new category.

Differences between continuous variables with normal distribution will be examined by Student's t-test. The Wilcoxon Sum-Rank Test will be used when continuous variables have failed in normality tests. To analyze categorical variables, chi-square will be used by the Fisher exact test or Yates correction. A two-tailed test with a value of p <0.05 will be considered statistically significant. ;
