Clinical outcomes of COVID-19 in long-term care facilities for people with epilepsy

COVID-19 response in a long-term care facility for people with epilepsy

OBJECTIVE

To assess asymptomatic rates and severity of SARS-CoV-2 infection in people with epilepsy and their healthcare workers in a long-term care facility which had implemented weekly surveillance testing between April 2020 and June 2022.

METHODS

Questionnaires focused on objective and subjective COVID-19 symptoms for people with epilepsy residing in and their healthcare workers at the Chalfont Centre for Epilepsy in June 2022. Demographic information, comorbidities, and seizure frequency were gathered from medical records. We also collected responses on objective and subjective COVID-19 symptoms from healthcare workers who participated in a prospective study assessing the reaction to COVID-19 vaccinations (SAFER).

RESULTS

Fifty-five out of 89 (62%) residents tested positive at least once on weekly PCR testing for SARS-CoV-2 during the period of interest; 20 of those (37%) were asymptomatic. In comparison, of those 63 healthcare workers who tested positive at least once on weekly testing during the same period, only four (6%) were asymptomatic. Of the 159 healthcare workers who also participated in the SAFER study, 41 tested positive at least once, and seven (17%) were completely asymptomatic during infection with SARS-CoV-2.

SIGNIFICANCE

People with epilepsy living in a long-term care facility were more likely to present with asymptomatic SARS-CoV-2 infections than healthcare workers at the same facility. Despite possible bias in the reporting of subjective symptoms due to management-by-proxy, there is no evidence that vulnerable people living in an epilepsy long-term care facility showed reduced resilience towards infections.

PLAIN LANGUAGE SUMMARY

People with epilepsy living in care home facilities had a surprisingly high degree of asymptomatic infections with SARS-CoV-2. Very few residents had severe or fatal outcomes. This is in stark contrast to the widely reported bad outcomes for people without epilepsy in other care homes. People with epilepsy reported significantly less symptoms than their healthcare workers. No changes in seizure frequency during or after infection were observed.

Incidence, severity and outcomes of COVID-19 in age and gender matched adults with and without epilepsy in Moscow: A historical cohort study

OBJECTIVE

We hypothesized that PWE have an increased risk to acquire COVID-19. This was a historical cohort study to determine COVID-19 incidence, severity, mortality and risk factors in adults with active epilepsy (PWE) compared to residents of Moscow without epilepsy matched by age, gender, and region of residence - Moscow Community Comparisons (MCC).

METHODS

Subjects were derived from a cohort of adult PWE and a cohort of age- and gender-matched population-based MCC without epilepsy identified in 2018. Incidence of COVID-19 was compared in each cohort from 01.03.2020 through 28.02.21. Influence of age, gender, comorbidities, and for the PWE cohort, epilepsy type, seizure frequency, and number/class of antiseizure medications was evaluated using Pearson's chi-squared test and logistic regression analysis.

RESULTS

We found 887 COVID-19 positive people in the two cohorts: 156 in PWE (51.8 ± 19.7 years) and 731 in MCC (52.0 ± 17.3 years,). COVID-19 incidence was lower in PWE: 13.8 % versus 18.7 % in MCC (p = 0.0002). In PWE no specific epilepsy related variables influenced incidence. Despite no difference in severity distribution in PWE versus MCC, hospitalization rate (37.6 % versus 25.5 %, p = 0.002), disease duration (57.1 % versus 47.1, p = 0.023), and mortality (10.9% versus 4.2 %, p = 0.0009) were significantly higher in PWE. Age and number of comorbidities significantly influenced COVID-19 incidence, severity, duration, and outcomes in both cohorts.

SIGNIFICANCE

Incidence of COVID-19 in PWE in Moscow was significantly lower compared to MCC. Age and comorbidities were strongly associated with severity, duration and outcomes of COVID-19 for all infected persons. Higher mortality in PWE may be explained by a higher number of comorbidities.

Long-term analysis of the effects of COVID-19 in people with epilepsy: Results from a multicenter on-line survey across the pandemic waves

PURPOSE

The worldwide pandemic caused by SARS-CoV-2 virus posed many challenges to the scientific and medical communities, including the protection and management of fragile populations. People with epilepsy (PWE) are a heterogenous group of subjects, with different treatment regimens and severity of symptoms. During the National lockdown, in Italy many patients with chronic conditions lost their regular follow-up program. The aim of this study was to investigate the impact of COVID-19 on their health status, from the start of the pandemic (March 2020) to July 2021 and one year later.

METHODS

We proposed an online questionnaire to subjects followed up at different epilepsy centers located in Milano, Monza & Lodi, three of Lombardy, Northern Italy, the most affected areas by the pandemic. Survey evaluated age, sex, characteristics of patients, type of epilepsy and therapies, COVID-19 diagnosis, vaccines, sleep quality, and anxiety status.

RESULTS

Among 178 analyzed surveys, 37 individuals reported symptoms of COVID-19 in closed contacts, including 9 with molecular diagnosis and 16 PWE performing the nasopharyngeal swab with 3 positive cases. One year later, 35 individuals reported at least one symptom overlapping with those typical of COVID-19, 8 received COVID-19 diagnosis, among which 6 were positive for SARS-CoV-2 infection. According to the sleep quality scale assessment, most PWE (52.3%) had poor sleep quality. Assessing anxiety status, 32 (38.1%) had a pathological score.

CONCLUSION

In this multicenter study, we observed that PWE do not appear to be at a higher risk of severe COVID-19. It will be fundamental monitoring this group to assess possible differences in long-COVID-19 and/or neuro-COVID-19 prevalence. On the other hand, our survey confirmed the impact of the pandemic on anxiety and quality of sleep in PWE. Thus, it is important to promptly recognize and treat psychological distress in PWE, because it could be a risk factor in seizure aggravation and quality-of-life deterioration. Telemedicine appears to be a useful tool to support patients with chronic diseases, such as epilepsy.

Occurrence and transmission potential of asymptomatic and presymptomatic SARS-CoV-2 infections: Update of a living systematic review and meta-analysis

BACKGROUND

Debate about the level of asymptomatic Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection continues. The amount of evidence is increasing and study designs have changed over time. We updated a living systematic review to address 3 questions: (1) Among people who become infected with SARS-CoV-2, what proportion does not experience symptoms at all during their infection? (2) What is the infectiousness of asymptomatic and presymptomatic, compared with symptomatic, SARS-CoV-2 infection? (3) What proportion of SARS-CoV-2 transmission in a population is accounted for by people who are asymptomatic or presymptomatic?

METHODS AND FINDINGS

The protocol was first published on 1 April 2020 and last updated on 18 June 2021. We searched PubMed, Embase, bioRxiv, and medRxiv, aggregated in a database of SARS-CoV-2 literature, most recently on 6 July 2021. Studies of people with PCR-diagnosed SARS-CoV-2, which documented symptom status at the beginning and end of follow-up, or mathematical modelling studies were included. Studies restricted to people already diagnosed, of single individuals or families, or without sufficient follow-up were excluded. One reviewer extracted data and a second verified the extraction, with disagreement resolved by discussion or a third reviewer. Risk of bias in empirical studies was assessed with a bespoke checklist and modelling studies with a published checklist. All data syntheses were done using random effects models. Review question (1): We included 130 studies. Heterogeneity was high so we did not estimate a mean proportion of asymptomatic infections overall (interquartile range (IQR) 14% to 50%, prediction interval 2% to 90%), or in 84 studies based on screening of defined populations (IQR 20% to 65%, prediction interval 4% to 94%). In 46 studies based on contact or outbreak investigations, the summary proportion asymptomatic was 19% (95% confidence interval (CI) 15% to 25%, prediction interval 2% to 70%). (2) The secondary attack rate in contacts of people with asymptomatic infection compared with symptomatic infection was 0.32 (95% CI 0.16 to 0.64, prediction interval 0.11 to 0.95, 8 studies). (3) In 13 modelling studies fit to data, the proportion of all SARS-CoV-2 transmission from presymptomatic individuals was higher than from asymptomatic individuals. Limitations of the evidence include high heterogeneity and high risks of selection and information bias in studies that were not designed to measure persistently asymptomatic infection, and limited information about variants of concern or in people who have been vaccinated.

CONCLUSIONS

Based on studies published up to July 2021, most SARS-CoV-2 infections were not persistently asymptomatic, and asymptomatic infections were less infectious than symptomatic infections. Summary estimates from meta-analysis may be misleading when variability between studies is extreme and prediction intervals should be presented. Future studies should determine the asymptomatic proportion of SARS-CoV-2 infections caused by variants of concern and in people with immunity following vaccination or previous infection. Without prospective longitudinal studies with methods that minimise selection and measurement biases, further updates with the study types included in this living systematic review are unlikely to be able to provide a reliable summary estimate of the proportion of asymptomatic infections caused by SARS-CoV-2.

Risk of COVID-19 Infection and of Severe Complications Among People With Epilepsy: A Nationwide Cohort Study

OBJECTIVE

To evaluate whether patients with epilepsy were more susceptible to coronavirus disease 2019 (COVID-19) infection and at greater risk of severe complications when infected with COVID-19 when compared with patients without epilepsy.

METHODS

We included participants who underwent at least one SARS-CoV-2 real-time reverse transcription polymerase chain reaction test between Jan 1 and June 4, 2020 from the Korean nationwide COVID-19 dataset. Epilepsy was defined according to the presence of diagnostic code in health claims data prior to the COVID-19 diagnosis. To investigate the association between epilepsy and the susceptibility or severe complications of COVID-19, a 1:6 ratio propensity score matching (PSM) and logistic regression analysis were performed. Severe complications with COVID-19 infection were defined as a composite of the incidence of mechanical ventilation, intensive care unit admission, and death within two months after COVID-19 diagnosis.

RESULTS

Among 212,678 study participants who underwent COVID-19 test, 3,919 (1.8%) had a history of epilepsy. After PSM, there was no significant difference in COVID-19 PCR positivity according to epilepsy history [odds ratio (OR): 0.86, 95% confidence interval (CI) 0.67-1.11]. Of the 7,713 individuals with confirmed COVID-19 infection, 72 (0.9%) had a history of epilepsy. Among the COVID-19 patients, the severe complications occurred in 444 (5.8%) individuals. After PSM, the presence of epilepsy was associated with occurrence of severe complications after COVID-19 infection [OR: 2.05, 95% CI: 1.04-4.04]. Mortality following COVID-19 infection did not differ according to the presence of epilepsy history [OR: 1.55, 95% CI: 0.65-3.70].

CONCLUSIONS

The presence of epilepsy was not associated with increased susceptibility to COVID-19 infection or mortality related to the infection. However, there was an increased risk of severe complications with COVID-19 in patients with epilepsy; therefore, careful management and monitoring may be necessary.

Epilepsy is overrepresented among young people who died from COVID-19: Analysis of nationwide mortality data in Hungary

BACKGROUND

Studies examining epilepsy as a COVID-related death risk have come to conflicting conclusions. Our aim was to assess the prevalence of epilepsy among COVID-related deaths in Hungary.

METHODS

Each COVID-19 infection case is required to be reported on a daily basis to the National Public Health Center of Hungary. This online report includes the beginning and end of the infection, as well as information on comorbidities. Death during infection is regarded as COVID-related. The anonymized data of each deceased patient are published on an information website (www.koronavirus.gov.hu) and provides up-to-date information on each patient with the date of death, the patient's sex, age, and chronic illness.

RESULTS

There were 11,968 patients who died of COVID-19 in Hungary between 13 March 2020 and 23 January 2021. Among 11,686 patients with no missing values for comorbidities, 255 patients had epilepsy (2.2%). Epilepsy was much more common among those who died at a young age: 9.3% of those who died under the age of 50 had epilepsy, compared with only 1.3% in those over the age of 80. The younger an age group was, the higher was the prevalence of epilepsy.

CONCLUSION

Patients who died of COVID-19 under the age of 50 were 10 to 20 times more likely to have epilepsy than what would have been expected from epidemiological data. Our results highlight the need for increased protection of young people with epilepsy from COVID-19 infection and the development of a vaccination strategy accordingly.

COVID-19 prevalence and mortality in people with epilepsy: A nation-wide multicenter study

BACKGROUND

To assess the prevalence, severity, and mortality of COVID-19 in people with epilepsy (PWE) and evaluate seizure control in PWE during and after COVID-19.

METHODS

Retrospective, observational, multicenter study conducted in 14 hospitals. Medical records of randomly selected PWE followed at neurology outpatient clinics were reviewed. Proportion of PWE with a positive test for SARS-CoV-2 during 2020 was calculated. Risk factors associated with COVID-19 and its morbimortality were evaluated.

RESULTS

2751 PWE were included, mean age 48.8 years (18-99), 72.4% had focal epilepsy, and 35% were drug-refractory. COVID-19 prevalence in PWE was 5.53%, while in the Spanish population was 4.26%. Proportion of admissions to hospital, ICU, and deaths in PWE were 17.1%, 2%, and 4.61% of COVID-19 cases, while in Spanish population were 10.81%, 0.95%, and 2.57%, respectively. A severe form of COVID-19 occurred in 11.8%; dyslipidemia, institutionalization at long-term care facilities, intellectual disability, and older age were associated risk factors. Older age, hypertension, dyslipidemia, cardiac disease, and institutionalization were associated with mortality from COVID-19. Seizure control was stable in 90.1% of PWE during acute COVID-19, while 8.6% reported an increase in seizure frequency. During post-COVID-19 follow-up, 4.6% reported seizure control worsening.

CONCLUSIONS

COVID-19 was moderately prevalent in PWE. One out of 5 patients required medical attention and 4.6% died due to COVID-19. Older age, dyslipidemia, institutionalization, and intellectual disability were significant risk factors associated with severe COVID-19. Seizure control remained stable during COVID-19 and throughout long-term follow-up in most PWE who contracted the infection.

The impact of SARS-CoV-2 vaccination in Dravet syndrome: A UK survey

BACKGROUND

The COVID-19 pandemic led to the urgent need for accelerated vaccine development. Approved vaccines have proved to be safe and well tolerated across millions of people in the general population. Dravet syndrome (DS) is a severe, early onset, developmental and epileptic encephalopathy. Vaccination is a precipitating factor for seizures. While there is no evidence that vaccine-precipitated seizures lead to adverse outcomes in people with DS, fear surrounding vaccination can remain for caregivers of people with DS, in some cases resulting in rejection of recommended vaccinations, leaving individuals more vulnerable to the relevant infections. A greater understanding of the safety profile of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination in this vulnerable group will help provide guidance for caregivers and clinicians when considering vaccination.

METHODS

A cross-sectional survey regarding COVID-19 and SARS-CoV-2 vaccine, in people with DS, was conducted by Dravet Syndrome UK (DSUK). Concomitantly, a review of individuals with DS who had recently received the SARS-CoV-2 vaccine, and who are resident at the Chalfont Centre for Epilepsy (CCE), or attend epilepsy clinics at the National Hospital for Neurology and Neurosurgery (NHNN), was undertaken.

RESULTS

Thirty-eight people completed the DSUK survey. Thirty-seven percent of caregivers reported being concerned about someone with DS receiving the SARS-CoV-2 vaccine; with some reporting that they would decline a vaccine when offered. Seventy-seven percent had not received any advice from a healthcare professional about the SARS-CoV-2 vaccination. 18/38 were eligible for SARS-CoV-2 vaccination, of whom nine had received their first vaccine dose. Combining the results of the DSUK survey and the review of individuals monitored at CCE or NHNN, fifteen people with DS had received their first dose of the SARS-CoV-2 vaccine. 11/15 (73%) reported at least one side effect, the most common being fatigue (6/15; 40%) and fever (6/15; 40%). Three individuals (20%) reported an increase in seizure frequency after the first vaccine dose. No increase in seizure frequency or duration was reported after the second dose.

CONCLUSION

Overall, these results suggest that SARS-CoV-2 vaccines are safe and well tolerated in individuals with DS, as they are in most people without DS. In most people with DS, SARS-CoV-2 vaccine does not appear to be associated with an increase in the frequency or duration of seizures, even in those who develop fever post-vaccination. Many caregivers are concerned about a person with DS receiving a SARS-CoV-2 vaccine, with some reporting that they would decline a SARS-CoV-2 vaccine when offered. It is crucial that healthcare professionals are proactive in providing accurate information regarding the risks and benefits of vaccination in this population, given the potential for serious outcomes from infection.

Impfung zur Vorbeugung der COVID-19-Erkrankung sowie Impfpriorisierung bei Epilepsie

Der Vorstand der Deutschen Gesellschaft für Epileptologie und die Kommission „Epilepsie und Synkopen“ der Deutschen Gesellschaft für Neurologie haben die aktuelle Datenlage zur Impfung zur Vorbeugung der Corona-Virus-Krankheit 2019 (COVID-19) sowie zur Impfpriorisierung bei Menschen mit Epilepsie gesichtet, diese zusammengefasst und geben die unten genannten Empfehlungen ab.

The impact of COVID-19 in Dravet syndrome: A UK survey

Objectives

To understand the risks, impact and outcome of COVID‐19 in people affected by Dravet Syndrome (DS).

Materials and Methods

An anonymous cross‐sectional online survey was conducted between June 17 and July 13, 2020, addressed to families of people with DS.

Results

A total of 116 responses were collected, from families of children (n = 86; 74%) and adults (30; 26%) with DS. The majority (106; 91%) were shielded at the family home during lockdown. Symptoms compatible with COVID‐19 were reported in 22 (19%) individuals. Only four individuals with symptoms had a PCR swab test, none of which was positive. Only one symptomatic person had antibody testing (but not swab testing), which was positive. One person had repeatedly positive swab tests whilst in hospital for renal failure, but had no typical symptoms of COVID‐19. In 50% of people with DS who developed possible or probable COVID‐19 symptoms, seizure worsening was reported, in terms of increased seizure frequency or duration or both. Medical attention was required in 9/22 (41%), all of whom were children.

Conclusions

In this cohort of people with DS, we observed an infection rate, determined by compatible symptoms, of 19%, with no deaths and benign outcome in most cases despite the underlying complex epilepsy although children often required medical attention. Early adoption of preventative measures, including testing of symptomatic individuals, regular surveillance for people living in residential care facilities, and shielding of individuals with comorbidities increasing the risk of severe outcome, may limit the impact of COVID‐19.

Epilepsy and COVID-19: Updated evidence and narrative review

The coronavirus disease 2019 (COVID-19) outbreak started in Wuhan, China, in late 2019 and rapidly spread globally. Vaccines have recently been developed and are being administered in some countries, but their widespread use is not yet sufficient; the battle against COVID-19 is protracted and people need to adapt to living under the influence of this disease. Epilepsy is a common chronic neurological condition characterized by spontaneous recurrence of unprovoked seizures. Various effects of COVID-19 on epilepsy have been studied in recent months. As clinicians, we need to keep up with daily updates in the evidence regarding interactions between COVID-19 and epilepsy. This review article summarizes the current evidence. Prospective studies on epilepsy and COVID-19 remain lacking. Most articles have comprised case reports, case series, retrospective studies, and recommendations/opinions that do not include data. However, summarizing these articles can identify the demands for research into COVID-19 and epilepsy by clarifying what is known and what remains unclear from current research.
