Clinical practice guidelines on the management of status epilepticus in adults: A systematic review.

OBJECTIVE: Status epilepticus (SE) is the second most common neurological emergency in adults. Despite improvements in the management of acute neurological conditions over the last decade, mortality is still durably high. Because a gap has emerged between SE management based on clinical practice guidelines (CPGs) and actual clinical practice, we conducted a systematic review of CPGs, assessing their quality, outlining commonalities and discrepancies in recommendations, and highlighting research gaps. METHODS: We searched the PubMed and EMBASE databases and other gray literature sources (nine among guideline registries, evidence-based medicine databases, point-of-care tools; seven websites of governmental organizations and international neurologic societies) in December 2021 (updated in November 2023). The units of analysis were CPGs that included recommendations on the diagnostic and/or therapeutic management of SE in adults. The quality of the CPGs was assessed using the AGREE II tool. RESULTS: Fifteen CPGs were included. The "Applicability" domain was assigned the lowest median score of 10%. The domains "Stakeholder Involvement", "Rigor of Development," and "Editorial Independence" were as well generally underrated. Recommendations on general and diagnostic management and on organizational interventions were fragmented and scattered. Recommendations on pre-hospital and hospital treatment of early-onset and refractory SE were broadly agreed, whereas there was less agreement on the treatment model and medications for established SE and super-refractory SE. SIGNIFICANCE: The CPGs for the management of SE developed in recent years are flawed by several methodological issues and discrepancies in the coverage of important topics. The gap between CPG-based management of SE and actual clinical practice may be due in part to the inherent limitations of the CPGs produced so far.

Impact of regulatory restrictions on the use of valproic acid in women of childbearing age: An Italian study.

OBJECTIVE: Due to significant risks to the offspring after intrauterine exposure, the European Medicines Agency issued recommendations in 2014 and 2018 restricting the use of valproate (VPA) in women of childbearing age (WOCA). We aimed to evaluate their impact in the Emilia-Romagna region (ERR) of Northern Italy. METHODS: Using administrative databases, we identified all the ERR residents who received antiseizure medication (ASM) prescriptions from 2010 to 2020. Time series of incidence rates by sex and age group were evaluated for all ASMs. Focusing on VPA, an interrupted time series analysis was applied to assess the impact of the restrictions in WOCA with epilepsy (WOCA-E) and WOCA with psychiatric disorders (WOCA-P). We then evaluated the chronological order of ASM prescriptions with regard to the position of VPA. RESULTS: Incidence rates of VPA prescriptions overall decreased over time. A significant decrease was observed only for females. The effect was stronger for WOCA, after both the first (incidence rate ratio [IRR] = .85, 95% confidence interval [CI] = .75-.96) and the second restriction (IRR = .67, 95% CI = .55-.82). The decrease was significant after the second restriction both for WOCA-E (IRR = .43, 95% CI = .27-.68) and for WOCA-P (IRR = .49, 95% CI = .35-.70), as well as VPA as a first prescription in both populations. VPA prescriptions as further choice did not show the same trend. SIGNIFICANCE: After the regulatory restrictions, an overall significant decline in the use of VPA in WOCA was observed in ERR. The second restriction has been effective in consolidating the prescription trend. However, VPA appears still to be a commonly used drug in WOCA when other ASMs have failed.

Neurological Manifestations of Long COVID: A Single-Center One-Year Experience.

Purpose: We report our single-center experience on the neurological manifestations of long COVID. Patients and Methods: This is a retrospective observational study. All consecutive patients referred to the neurological long COVID outpatient clinic of our institute from January 21 2021 to December 9 2021 underwent a general neurological objective examination. Treatments and investigations (brain MRI, neuropsychological evaluation, or others) were prescribed on an individual basis as per standard clinical practice. A follow-up visit was performed when appropriate. Descriptive statistics were presented as absolute and relative frequencies for categorical variables and as means, median, and ranges for continuous variables. Results: One hundred and three patients were visited (mean age 50.5 ±36 years, 62 females). The average time from acute COVID-19 infection to the first visit to our outpatient clinic was 243 days. Most patients presented with a mild form of acute COVID-19, with only 24 cases requiring hospitalization. The neurological symptoms mostly (n=70/103, 68%) started during the acute phase (before a negative swab for SARS-CoV-2). The most frequent acute manifestations reported, which lately became persistent, were fatigue (n=58/103, 56%), olfactory/taste dysfunction (n=58/103, 56%), headache (n=47/103, 46%), cognitive disorders (n=46/103, 45%), sleep disorders (n=30/103, 29%), sensitivity alterations (n=29/103, 28%), and dizziness (n=7/103, 7%). Tremor was also reported (n=8/103, 7%). Neuropsychological evaluation was performed in 30 patients and revealed alterations in executive functions (n=6/30, 20%), memory (n=11/30, 37%), with pathological depressive (n=9/30, 30%) and anxiety (n=8/30, 27%) scores. Brain MRIs have been performed in 41 cases, revealing nonspecific abnormal findings only in 4 cases. Thirty-six patients underwent a follow-up, where a general improvement was observed but rarely (n=2/36) a complete recovery. Conclusion: The majority of patients presenting persistent neurological symptoms (most frequently fatigue, cognitive disorders, and olfactory dysfunctions) developed a previous mild form of COVID-19. Further studies are required to develop therapeutic strategies.

Epilepsy With Auditory Features: From Etiology to Treatment.

Epilepsy with auditory features (EAF) is a focal epilepsy belonging to the focal epileptic syndromes with onset at variable age according to the new ILAE Classification. It is characterized by seizures with auditory aura or receptive aphasia suggesting a lateral temporal lobe involvement of the epileptic discharge. Etiological factors underlying EAF are largely unknown. In the familial cases with an autosomal dominant pattern of inheritance several genes have been involved, among which the first discovered, LGI1, was thought to be predominant. However, increasing evidence now points to a multifactorial etiology, as familial and sporadic EAF share a virtually identical electro-clinical characterization and only a few have a documented genetic etiology. Patients with EAF usually have an unremarkable neurological examination and a good response to antiseizure medications. However, it must be underscored that total remission might be lower than expected and that treatment withdrawal might lead to relapses. Thus, a proper understanding of this condition is in order for better patient treatment and counseling. Further studies are still required to further characterize the many facets of EAF.

The Impact of the COVID-19 Pandemic on People With Epilepsy. An Italian Survey and a Global Perspective.

Objectives: We explored the impact of the coronavirus disease-19 (COVID-19) emergency on the health of people with epilepsy (PwE). We also investigated their attitude toward telemedicine. Methods: The PubMed database up to September 10, 2020 was searched for questionnaire-based studies conducted in PwE during the COVID-19 emergency, and the literature retrieved was reviewed. In addition, all patients who had a telephone consultation with our center between May 7 and July 31, 2020 were invited to fill in a 57-item online questionnaire focusing on epilepsy and comorbidities, any changes in lifestyle or clinical conditions and any emergency-related problems arising during the COVID-19 emergency, and their views on telemedicine. Associations between variables were detected through X 2 test and Fisher's exact test. Univariate and multivariate logistic regression models were used to evaluate the effects of different factors on clinical conditions. Results: Twelve studies met the literature search criteria. They showed that the rate of seizure worsening during the emergency ranged from 4 to 35% and was mainly correlated with epilepsy severity, sleep disturbances and COVID-19-related issues. Our questionnaire was filled in by 222 PwE or caregivers. One hundred (76.6%) reported unchanged clinical conditions, 25 (11.3%) an improvement, and 27 (12%) a deterioration. Reported clinical worsening was associated with a psychiatric condition and/or medication (OR = 12.59, p < 0.001), sleep disorders (OR = 8.41, p = 0.001), limited access to healthcare (OR = 4.71, p = 0.016), and experiencing seizures during the emergency (OR = 4.51, p = 0.007). Telemedicine was considered acceptable by 116 subjects (52.3%). Conclusions: Most PwE did not experience a significant change in their clinical conditions during the COVID-19 emergency. However, severity of epilepsy, concomitant disability, comorbid psychiatric conditions, sleep disorders and limited access to healthcare may affect their health.
