Drug-resistant epilepsy in Morocco: description, prevalence and predictive factors in Casablanca-Settat region.

Drug-resistant epilepsy (DRE) affects about one-third of people with epilepsy (PWE). Our study aims to estimate the DRE prevalence and its predictive factors in Morocco. A cross-sectional study was conducted over 18 months. PWE with clinical diagnosis of epilepsy, and with an antiseizure treatment duration >12 months were examined in the neurology, neurosurgery, psychiatry, and pediatrics departments, of different sampled clinical sectors for the Casablanca-Settat region. Sociodemographic and clinical data were collected using a questionnaire during consultations. Antiseizure multi-therapy, a seizure freedom duration <12 months, compliance, and adequate posology were the determining factors for classifying DRE. Data were analyzed using Statistical Package for Social Sciences (SPSS) software, version 21.0. Statistical significance was set at p < 0.05 and logistic regression was performed to determine the predictive factors. In our sample of 446 PWE, the median age is 25 years (IQR: 11.75-44.00). The DRE estimated prevalence was 29.4 %. Pseudo-resistant epilepsy (PRE) was 18.0 %. Multivariate logistic regression analysis reports that single marital status (ORa = 1.94; CI95%: 1.02-3.71), comorbidities and concomitant affections (ORa = 2.14; CI95%: 1.27-3.59), structural etiology (ORa = 1.96; CI95%: 1.16-3.30), pre-ictal aura (ORa = 1.90; CI95%: 1.09-3.29), inter-ictal EEG abnormalities (ORa = 2.45; CI95%: 1.24-4.84) and allopathic treatment use (ORa = 2.10; CI95%: 1.30-3.39) are the predictive factors for DRE. We report an alarming DRE prevalence. Associated factors found may contribute to the prognosis and early management. PWE awareness, facilitating healthcare access and the development of epilepsy surgery are the key points to limit DRE in Morocco and prevent its various complications, especially for the pediatric population.

Prevalence and associated factors of psychiatric comorbidities in epilepsy in the Casablanca-Settat region of Morocco: A cross-sectional study.

OBJECTIVE: To determine the estimated prevalence of anxiety, depression, and anxiety-depression syndrome (ADS) and to identify the associated factors in Moroccan people with epilepsy (PWE). METHOD: A cross-sectional study was conducted among adult PWE (June 2021-December 2022) in the Casablanca-Settat region. PWE were interviewed by completing a questionnaire collecting sociodemographic and clinical data. Anxiety and depression were assessed by the Hospital Anxiety and Depression Scale (HADS). Out of 21 points, a score ≥8 is in favor of considerable anxiety/depression symptoms and a sum of the two scores ≥15 indicates the presence of ADS. Data were analyzed using Statistical Package for Social Sciences (SPSS) 21.0. p-values ≤0.05 were considered statistically significant and logistic regression was performed to determine the associated factors. RESULTS: Among 294 PWE, the median age was 39 years (interquartile range [IQR]: 25.75-54.00). The median anxiety, depression, and ADS scores were 8 (IQR: 5.00-10.00), 7 (IQR: 4.00-10.00), and 15 (IQR: 10.00-20.00), respectively. Anxiety, depression, and ADS were revealed in 51.4%, 44.9%, and 51.0% of PWE, respectively. Depression was the only predictor for anxiety (aOR = 24.20; 95%CI: 12.45-47.01). Antiseizure polytherapy (aOR = 3.35; 95%CI: 1.72-6.54) and anxiety (aOR = 24.04; 95%CI: 12.12-47.67) were the factors associated with depression. The risk of ADS was increased by female gender (aOR = 2.83; 95%CI: 1.68-4.78), antiseizure polytherapy (aOR = 2.75; 95%CI: 1.62-4.65), structural epilepsy (aOR = 1.73; 95%CI: 1.01-2.94), and the presence of concomitant conditions with epilepsy (aOR = 1.96; 95%CI: 1.16-3.31). SIGNIFICANCE: Our study reports high psychiatric comorbidity prevalence in epilepsy, which supports the bidirectional link hypothesis. Associated factors found are important in the prognosis and prevention. PLAIN LANGUAGE SUMMARY: The neural mechanisms underlying epilepsy tend to expose PWE to psychiatric disorders. Our study aims to quantify the rate of psychiatric comorbidities and their predictive factors in Moroccan PWE. The estimated prevalences of significant symptoms of anxiety, depression, and ADS were 51.4%, 44.9%, and 51.0%, respectively. Depression was the predictor of anxiety. Antiseizure polymedication and anxiety were the associated factors with depression. The risk of SAD was increased by female gender, antiseizure polymedication, structural epilepsy, and concomitant diseases with epilepsy. Our results are important for considering the psychiatric aspect of PWE and improving their care and quality of life.

Antiseizure medication adherence and epilepsy surgery attitude in people with epilepsy in Morocco: A cross-sectional study.

We determine the proportion of non-Antiseizure Medication Adherence (non-AMA) and refusal attitude towards Epilepsy Surgery (ES) and their associated factors in Moroccan People With Epilepsy (PWE). A cross-sectional study was conducted (December 2021-December 2022) among adult Moroccan PWE. PWE were interviewed for their reactions to AMA and the ES attitude. Their medical files were processed to complete their sociodemographic and clinical data. Data were analyzed by the Statistical Package for Social Sciences (SPSS) software 21.0. A Chi-square test was performed to compare variables and multivariate logistic regression was used to highlight associations. Statistical tests were considered significant at a p-value ≤ 0.05 for a Confidence Interval (CI) of 95 %. The median age of our sample (n = 294) was 38 years (IQR: 25.00-55.00). Non-AMA was noted in 24.5 % with indifference as the main reason (55.6 %). ES refusal was found in 33.3 %, attributed mostly to apprehension (61.2 %). In the multivariate analysis, male sex (aOR = 1.94; 95 %CI: 1.03-3.64) and the existence of a family history of epilepsy (aOR = 1.96; 95 %CI: 1.02-3.75) were the factors associated with the non-AMA, whereas the use of allopathic treatments (aOR = 2.32; 95 %CI: 1.20-4.51), exclusively focal or generalized (not combined) seizures (aOR = 2.66; 95 %CI: 1.36-5.21) and the combination of a generic with the originator ASM (aOR = 2.64; 95 %CI: 1.12-6.18) were the predictive factors with the ES refusal attitude. The proportions found of non-AMA and ES refusal were relatively low compared to other studies, which may indicate the effort that medical staff have devoted recently to raising awareness of the importance of PWE's therapeutic involvement.
