Epilepsy and neurocysticercosis in rural areas of the Bolivian Chaco: What has changed during the last 30 years? Epilepsia Open 2024; 9:513-521. [PMID: 38016915 PMCID: PMC10984303 DOI: 10.1002/epi4.12872] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2023] [Accepted: 11/21/2023] [Indexed: 11/30/2023] Open
Abstract
OBJECTIVE Neurocysticercosis (NCC) is considered the major cause of epilepsy in endemic regions. In the rural areas of the Bolivian Chaco prevalence of NCC among people with epilepsy (PWE) was 27.4%, according to a population-based survey carried out in 1994. The aim of the study was to estimate the prevalence of Epilepsy Associated with Tonic-Clonic Seizures (EATCS) and to evaluate the prevalence of NCC among PWE in the rural communities of the Bolivian Chaco after 30 years. METHODS Twenty-two rural communities (total population 12 852) were involved in the study. PWE in the study area were ascertained by multiple sources and the diagnosis was confirmed by a neurologist. All PWE identified were invited to undergo brain CT scan examination and diagnosis of NCC was sought according to the revised Del Brutto criteria. RESULTS Seventy-eight PWE (30 men, 38.4%; mean age at onset was 12.7 ± 13.2 years) with EATCS were identified giving a crude prevalence of 6.1/1000 (95% CI: 4.7-7.3). Due to the COVID-19 lockdown, the study was interrupted in 2020 and only 36 PWE (46%) of the whole sample underwent CT scan examination. Of these, 8 (22.2%) fulfilled the criteria for NCC of whom 6 (75%) presented only single or multiple calcifications. SIGNIFICANCE This is the first study reassessing the prevalence of NCC among PWE after 30 years, in the same rural area and using a population-based design. T. solium is still endemic in the Bolivian Chaco where more than 20% of EATCS may be attributable to NCC. Our findings show a substantially unchanged prevalence of NCC over the past 30 years despite improved knowledge, underlining the need for active intervention programs to control T. solium transmission in this area. PLAIN LANGUAGE SUMMARY Neurocysticercosis is still endemic in the Bolivian Chaco. The proportion of epilepsy attributable to neurocysticercosis is about 22%. Systematic efforts towards elimination of neurocysticercosis in these areas should be implemented.

Abstract
OBJECTIVES Up to 85% of people living with epilepsy (PwE) reside in low-and middle-income countries. In sub-Saharan Africa, the lifetime prevalence of epilepsy is 16 per 1000 persons. In Northern rural Rwanda, a 47.7 per 1000 prevalence has been reported. As variations in prevalence across geographical areas have been observed, we studied the prevalence in Southern rural Rwanda using the same robust methodology as applied in the North. METHODS We conducted a three-stage, cross-sectional, door-to-door survey in two rural villages in Southern Rwanda from June 2022 to April 2023. First, trained enumerators administered the validated Limoges questionnaire for epilepsy screening. Second, neurologists examined the persons who had screened positively to confirm the epilepsy diagnosis. Third, cases with an inconclusive assessment were separately reexamined by two neurologists to reevaluate the diagnosis. RESULTS Enumerators screened 1745 persons (54.4% female, mean age: 24 ± 19.3 years), of whom 304 (17.4%) screened positive. Epilepsy diagnosis was confirmed in 133 (52.6% female, mean age: 30 ± 18.2 years) and active epilepsy in 130 persons. Lifetime epilepsy prevalence was 76.2 per 1000 (95% CI: 64.2-89.7‰). The highest age-specific rate occurred in the 29-49 age group. No gender-specific differences were noted. In 22.6% of the PwE, only non-convulsive seizures occurred. The treatment gap was 92.2%, including a diagnosis gap of 79.4%. CONCLUSION We demonstrated a very high epilepsy prevalence in Southern rural Rwanda, with over 20% of cases having only non-convulsive seizures, which are often underdiagnosed in rural Africa. In line with previous Rwandan reports, we reiterate the high burden of the disease in the country. Geographic variation in prevalence throughout Africa may result from differences in risk and aetiological factors. Case-control studies are underway to understand such differences and propose adapted health policies for epilepsy prevention.

Abstract
OBJECTIVE The objective of this study is to estimate the prevalence of epilepsy with Tonic-Clonic (TC) seizures in rural areas of the Bolivian Gran Chaco and to evaluate the usefulness of telemedicine in this context. METHODS The study was carried out in the Isozo Area, southern-eastern Bolivia. Twenty-five rural communities with a population of 8258 inhabitants were included in the survey. Trained community-health workers administered a validated single screening question to the householders (stage I). A second face-to-face questionnaire was administered to each positive subject (stage II). At stage II subjects were also screened using the smartphone app "Epilepsy Diagnosis Aid". Subjects screened positive at stage II underwent a complete neurological examination to confirm the diagnosis (stage III). Due to the COVID-19 lockdown, some subjects have been evaluated through a digital platform (Zoom®). RESULTS One-thousand two-hundred and thirteen interviews were performed at stage I, corresponding to a total screened population of 6692 inhabitants. Thirty-eight screened positive were identified at stage I and II and of these, 28 people with epilepsy were identified, giving an overall prevalence of 4.2/1000 (95% CI 2.6-5.7). Prevalence rate steeply increased with age reaching a peak of 7.9/1000 in the population aged 20-29 years without significant differences between women and men. For almost 50% of the screened positive subjects, confirmation of epilepsy by a neurologist at stage III was achieved through simple videoconsultation. After a simultaneous awareness campaign, 22 self-reported PWE requested a consultation and, among them, 11 had a diagnosis of epilepsy confirmed. SIGNIFICANCE This study shows a prevalence estimate close to those reported for LMIC. Simple videoconsultation and specific apps may be valuable tools in epidemiological research. Awareness campaigns are important allies for a full case identification, particularly in contexts where higher rates of stigma are recorded.

Community-level prevalence of epilepsy and of neurocysticercosis among people with epilepsy in the Balaka district of Malawi: A cross-sectional study. PLoS Negl Trop Dis 2022; 16:e0010675. [PMID: 36108075 PMCID: PMC9477368 DOI: 10.1371/journal.pntd.0010675] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2022] [Accepted: 07/19/2022] [Indexed: 11/18/2022] Open
Abstract
Background
Epilepsy and neurocysticercosis (NCC) prevalence estimates in sub-Saharan Africa are still scarce but show important variation due to the population studied and different screening and diagnosis strategies used. The aims of this study were to estimate the prevalence of epileptic seizures and epilepsy in the sampled population, and the proportion of NCC among people with epilepsy (PWE) in a large cross-sectional study in a rural district of southern Malawi.
Methods
We conducted a community-based door-to-door screening study for epileptic seizures in Balaka, Malawi between October and December 2012. Past epileptic seizures were reported through a 15-item questionnaire answered by at least one person per household generating five major criteria. People who screened positive were further examined by a neurologist to establish diagnosis. Patients diagnosed with epilepsy were examined and offered Taenia solium cyst antigen and antibody serological tests, and a CT scan for the diagnosis of NCC.
Results
In total, screening information on 69,595 individuals was obtained for lifetime occurrence of epileptic seizures. 3,100 (4.5%) participants screened positive, of whom 1,913 (62%) could be followed-up and underwent further assessment. Lifetime prevalence was 3.0% (95% Bayesian credible interval [CI] 2.8 to 3.1%) and 1.2% (95%BCI 0.9 to 1.6%) for epileptic seizures and epilepsy, respectively. NCC prevalence among PWE was estimated to be 4.4% (95%BCI 0.8 to 8.5%). A diagnosis of epilepsy was ultimately reached for 455 participants.
Conclusion
The results of this large community-based study contribute to the evaluation and understanding of the burden of epilepsy in the population and of NCC among PWE in sub-Saharan Africa.

Abstract
INTRODUCTION Epilepsy affects >50 million people worldwide, with 80% of them living in low- and middle-income countries (LMICs). Studies with a standardized methodology are required to obtain comparable data on epilepsy and implement health policies in order to reduce the treatment gap and improve the diagnosis and management of epilepsy. In 2000, following the guidelines of the International League Against Epilepsy (ILAE), the "questionnaire for investigation of epilepsy in tropical countries" (IENT questionnaire) was developed to promote epidemiological surveys on epilepsy using a standard methodology. This study aims to describe how, when, where, and why the IENT questionnaire has been used through epidemiological studies on epilepsy over the last 2 decades and to acquire users' opinions about the tool. METHODS Studies that used the IENT questionnaire were searched through international and local bibliographic databases, including the gray literature. An online survey was carried out, including a snowball effect. Original research studies were included. Characteristics of the studies and populations and general information on the instrument and its use were collected. RESULTS Eighty-two documents were selected referring to 61 studies that were mostly carried out on the African continent (n = 54). Most of them aimed to determine the prevalence (n = 31) and associated factors (n = 28) of epilepsy in LMICs. Among the 61 studies, 35 were population-based, and 30 included both adults and children. A methodological heterogeneity was found between studies, and in cases where the IENT questionnaire alone did not ensure complete data collection, other tools were used concomitantly (n = 40). DISCUSSION/CONCLUSION Over the last 2 decades, the IENT questionnaire has been continuously used in different LMICs. This result favors its promotion and updating, with the inclusion of new topics related to epilepsy (e.g., comorbidities, quality of life, and stigma), current ILAE guidelines, and digital versions.

Abstract
Objectives Epileptic seizures and epilepsy in urban settings of low-income and middle-income countries (LMIC) are largely under-researched, but their prevalence is necessary for good healthcare planning. This study aimed to determine the lifetime prevalence of epileptic seizures and epilepsy in urban Dar es Salaam. Methods Nearly 50,000 people in former Kinondoni district, Dar es Salaam, were screened for epileptic seizures using a set of nine questions. Answers to these nine questions were categorized into generalized, focal, and unspecified seizures. Screening positivity rates were adjusted for questionnaire inaccuracy using two scenarios to analyse true epilepsy prevalences. Results Overall, 1085 (2.23%) people fulfilled the criteria for ever having had at least one type of epileptic seizure. Two-hundred-ninety-six (0.60%) people screened positive for generalized seizures, 986 (2.02%) for focal seizures, and 32 (0.07%) for unspecified seizures. Women more commonly screened positive than men (2.61% versus 1.72%, p < 0.001), particularly for focal seizures (p < 0.001). Adjusting for different degrees of accuracy of the screening questionnaire yielded true lifetime prevalences for epilepsy of any type between 1.59% and 2.41%. We furthermore observed a considerable variation of screening positivity rates between wards in Kinondoni district (p < 0.001). Conclusion The prevalence of epilepsy, based on a questionnaire survey in urban Tanzania, was higher than previously observed, probably due to the screening questionnaire, which contained questions specifically designed to identify focal seizures. Further studies on epileptic seizures/epilepsy are needed for urban settings in LMIC, preferably with an integrated follow-up of positive cases. Data on epilepsy in urban African populations are scarce Reliable prevalence estimates for epilepsy are important for healthcare planning but difficult to obtain Epilepsy screening tools need to be developed carefully in a participatory approach Focal and non-convulsive seizures are often overlooked in studies Epilepsy prevalence in urban Tanzania is similar to other parts of Africa

Abstract
BACKGROUND We developed and validated a Spanish seizure screen for children based on a previously validated English seizure screen that could be administered by a trained research assistant in a 2-step process, approximating the clinical diagnostic process of a pediatric epilepsy specialist. This questionnaire was designed to study seizure prevalence in a research population of children at risk for epilepsy. METHODS Spanish-speaking parents of children 6 months to 17 years old were recruited from the pediatric neurology clinics at Boston Medical Center and interviewed using a computerized questionnaire. A computerized algorithm of parent responses rendered a seizure classification of positive or negative. Blinded to questionnaire results, pediatric neurologists served as the diagnostic gold standard, ranking each patient event using a 4-level scale based on clinical history and examination: (1) not likely, (2) indeterminate, (3) probable, and (4) almost certain where rankings of 3 or 4 lead to a diagnosis of seizure. RESULTS The questionnaire was completed by 163 enrolled parents. The seizure screen demonstrated a 94.2% sensitivity and 93.7% specificity for identifying seizures. The positive predictive value was 87.5%, and the negative predictive value was 97.2%. CONCLUSIONS This pediatric seizure questionnaire was both sensitive and specific for detecting clinically confirmed seizures. This tool may be useful to clinicians and researchers in screening large populations of children, decreasing the time and cost of added neurologic assessments.

Abstract
INTRODUCTION The Coronavirus disease 2019 (COVID-19) has put some health systems under pressure, especially in low- and middle-income countries. We aimed at evaluating the impact of COVID-19 emergency on the management of people with epilepsy (PWE) living in the rural communities of the Gran Chaco area of the Plurinational State of Bolivia. MATERIALS AND METHODS We selected a sample of PWE living in the rural communities of the Bolivian Chaco. A standardized questionnaire was developed, consisting of six questions addressing drug availability, drug discontinuation, personnel responsible for drug retrieval during the lockdown, and the presence of seizures in the two months preceding the interview. Questionnaires were administered by community health workers of the rural health centers in September 2020. RESULTS Seventy PWE (38 men, 54.3%; mean age 26.9 ± 16.7) were interviewed. During the lockdown the large majority of them (n = 51, 73.9%) reported an irregular medication intake mainly due to the lack of antiseizure medications in the local health posts, leading to an increase in seizure frequency. CONCLUSION The COVID-19 pandemic has unmasked the frailty of the Bolivian health system, especially for the management of chronic diseases such as epilepsy in the rural communities.

Abstract
BACKGROUND Sudden unexpected death in epilepsy (SUDEP) is a rare but fatal risk that patients, parents, and professional societies clearly recommend discussing with patients and families. However, this conversation does not routinely happen. OBJECTIVES This pilot study aimed to demonstrate whether computerized decision support could increase patient communication about SUDEP. METHODS A prospective before-and-after study of the effect of computerized decision support on delivery of SUDEP counseling. The intervention was a screening, alerting, education, and follow-up SUDEP module for an existing computerized decision support system (the Child Health Improvement through Computer Automation [CHICA]) in five urban pediatric primary care clinics. Families of children with epilepsy were contacted by telephone before and after implementation to assess if the clinician discussed SUDEP at their respective encounters. RESULTS The CHICA-SUDEP module screened 7,154 children age 0 to 21 years for seizures over 7 months; 108 (1.5%) reported epilepsy. We interviewed 101 families after primary care encounters (75 before and 26 after implementation) over 9 months. After starting CHICA-SUDEP, the number of caregivers who reported discussing SUDEP with their child's clinician more than doubled from 21% (16/75) to 46% (12/26; p = 0.03), and when the parent recalled who brought up the topic, 80% of the time it was the clinician. The differences between timing and sampling methodologies of before and after intervention cohorts could have led to potential sampling and recall bias. CONCLUSION Clinician-family discussions about SUDEP significantly increased in pediatric primary care clinics after introducing a systematic, computerized screening and decision support module. These tools demonstrate potential for increasing patient-centered education about SUDEP, as well as incorporating other guideline-recommended algorithms into primary and subspecialty cares.

Usefulness of a smartphone application for the diagnosis of epilepsy: Validation study in high-income and rural low-income countries. Epilepsy Behav 2021; 115:107680. [PMID: 33348193 DOI: 10.1016/j.yebeh.2020.107680] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/15/2020] [Revised: 11/28/2020] [Accepted: 11/28/2020] [Indexed: 11/20/2022]
Abstract
INTRODUCTION In low- and middle-income countries (LMIC), the diagnosis of epilepsy should be made by Non-Physician Health Workers (NPHW) who are widely available in these settings. Recently a smartphone app (Epilepsy Diagnosis Aid) has been developed and validated to be used by NPHW, in order to confirm the diagnosis of epilepsy. The aim of our study was to perform a validation of the app in two different contexts: a hospital-based setting of a high-income country (HIC) and a population-based setting of the rural communities of a LMIC. MATERIAL AND METHODS For the hospital-based setting, the app was administered to a sample of patients with epilepsy (PWE) and to a sample of subjects affected by syncope attending the epilepsy center of the University of Catania. For the population-based setting, performed in the rural communities of the Gran Chaco region in Bolivia,the app was administered by NPHW to a sample of PWE previously identified. Sensitivity and specificity were calculated for the diagnosis of epilepsy. RESULTS In the hospital-setting, the app was administered to 100 PWE and 20 syncopes. A probability score > 80 showed a sensitivity of 76% (95%CI 66.4-84) and a specificity of 100% (95%CI 83.2-100) for the diagnosis of epilepsy; higher values were found for active epilepsy with tonic-clonic seizures. In the rural-setting, the app was administered to 38 PWE, giving a sensitivity of 92.1% (95%CI 78.6-98.3). CONCLUSION The app for epilepsy could represent a valuable instrument, which can be easily employed by trained NPHW to diagnose epilepsy in primary health-care settings of LMIC.

Calibration of the Epilepsy Questionnaire for Use in a Low-Resource Setting. JOURNAL OF ENVIRONMENTAL AND PUBLIC HEALTH 2020; 2020:5193189. [PMID: 32934658 PMCID: PMC7479480 DOI: 10.1155/2020/5193189] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/01/2020] [Revised: 08/01/2020] [Accepted: 08/21/2020] [Indexed: 01/02/2023]
Abstract
Background. Burden of epilepsy in sub-Saharan Africa is huge in the midst of shortage of human resource in its health sector. Using skilled staff to supervise and support lower level healthcare workers providing frontline primary healthcare is a pragmatic coping solution. But, lower level health providers face enormous challenges due to absent clinical algorithms or pragmatic rapid diagnostic tests. Objective. This study aimed to determine if the use of an epilepsy questionnaire in a traditional clinical setting would improve semiological details obtained and diagnostic accuracy. Methods. A prospective study was conducted involving patients diagnosed with epilepsy each with an eye witness who had regularly witnessed the seizures. Routine seizure history from clinical documentation and an interviewer-based questionnaire were compared. The data obtained were assessed for content, accuracy, intermethod and test-retest reliability. Results. Sixty-seven patients with a median age of 24 years were recruited. Routine seizure history had obtained less semiological details with inadequate description of nonmotor manifestations and lateralizing motor details. The questionnaire-obtained history showed higher accuracy for generalized onset seizure (0.83 vs. 0.56) and focal onset seizures (0.79 vs. 0.59). The questionnaire-obtained history also had good test-retest reliability for various semiological domains except automatisms. Conclusions. Routine seizure histories are not standardized. The use of a questionnaire goes a long way in improving semiology description in a low-resource setting and guides the health provider on what details to focus on. The use of epilepsy questionnaires should, therefore, be considered to improve semiology, especially in nonspecialist settings.

Abstract
The majority of the screening questionnaires for epilepsy have been validated in hospital settings. We previously developed and used for field validation a screening tool to detect generalized tonic-clonic seizures (GTCS) in the rural communities of the Chaco region of Bolivia. The objective of the present study was to perform a hospital-based validation of the same questionnaire and to compare the levels of accuracy obtained when validated in the field or in a hospital-based context. We carried out a hospital-based validation in the Hospital Hernandez Vera of Santa Cruz, Bolivia, where we enrolled patients affected by epilepsy with GTCS and controls. Sensitivity, specificity, and positive and negative predictive values (PPV and NPV) were calculated. One hundred twenty questionnaires were administered to 59 patients (27 men [45.8%]; mean age ± SD = 32.4 ± 14.2 years) and 61 controls (27 men [44.3%]; mean age ± SD = 32.6 ± 14.3 years). We obtained levels of accuracy of 100%. Sensitivity and PPV were significantly higher than the estimates obtained in the field-validation study (sensitivity 100% vs 76.3%; PPV 100% vs 69.0%). Our screening questionnaire showed a significantly lower level of sensitivity when validated in the field, confirming that hospital-based validation can lead to an overestimation of sensitivity.

Infect Dis Poverty 2019; 8:11. [PMID: 30738437 PMCID: PMC6368958 DOI: 10.1186/s40249-019-0523-y] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2018] [Accepted: 01/23/2019] [Indexed: 12/04/2022] Open
Abstract
BACKGROUND Onchocerciasis-endemic regions are known to have a high epilepsy prevalence. Limited resources in these areas and poor access to healthcare by persons with epilepsy (PWE) result in a wide anti-epileptic treatment gap, poor seizure control and a high burden of seizure-related complications. Recent community-based surveys highlight the need for epilepsy management strategies suitable for remote onchocerciasis-endemic villages to ensure better health outcomes for PWE. In this paper, we propose a feasible approach to manage PWE in such settings. MAIN TEXT Improved management of PWE in onchocerciasis-endemic areas may be achieved by decentralizing epilepsy care. Simplified approaches for the diagnosis and treatment of epilepsy may be used by non-physicians, under the supervision of physicians or specialists. To reduce the treatment gap, a regular supply of subsidized anti-epileptic drugs (AED) appropriate for different types of onchocerciasis-associated epilepsy should be instituted. Setting up a community-based epilepsy surveillance system will enable early diagnosis and treatment of PWE thereby preventing complications. Community awareness programs on epilepsy must be implemented to reduce stigma and facilitate the social rehabilitation of PWE. Finally, strengthening onchocerciasis elimination programs by optimizing community-directed treatment with ivermectin (CDTI) and considering alternative treatment strategies might reduce the incidence of epilepsy. CONCLUSIONS A community-based approach with task-shifting of epilepsy care from specialists to non-physician health workers will reduce epilepsy-associated morbidity. Increased advocacy and collaboration with various stakeholders is needed to establish a sustainable, cost-effective chronic care model for epilepsy that will significantly improve the quality of life of PWE in onchocerciasis-endemic regions.

PLoS Negl Trop Dis 2019; 13:e0007109. [PMID: 30653519 PMCID: PMC6353216 DOI: 10.1371/journal.pntd.0007109] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2018] [Revised: 01/30/2019] [Accepted: 12/22/2018] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Epilepsy and progressively worsening severe chronic headaches (WSCH) are the two most common clinical manifestations of neurocysticercosis, a form of cysticercosis. Most community-based studies in sub-Saharan Africa (SSA) use a two-step approach (questionnaire and confirmation) to estimate the prevalence of these neurological disorders and neurocysticercosis. Few validate the questionnaire in the field or account for the imperfect nature of the screening questionnaire and the fact that only those who screen positive have the opportunity to be confirmed. This study aims to obtain community-based validity estimates of a screening questionnaire, and to assess the impact of verification bias and misclassification error on prevalence estimates of epilepsy and WSCH. METHODOLOGY/PRINCIPAL FINDINGS Baseline screening questionnaire followed by neurological examination data from a cluster randomized controlled trial collected between February 2011 and January 2012 were used. Bayesian latent-class models were applied to obtain verification bias adjusted validity estimates for the screening questionnaire. These models were also used to compare the adjusted prevalence estimates of epilepsy and WSCH to those directly obtained from the data (i.e. unadjusted prevalence estimates). Different priors were used and their corresponding posterior inference was compared for both WSCH and epilepsy. Screening data were available for 4768 individuals. For epilepsy, posterior estimates for the sensitivity varied with the priors used but remained robust for the specificity, with the highest estimates at 66.1% (95%BCI: 56.4%;75.3%) for sensitivity and 88.9% (88.0%;89.8%) for specificity. For WSCH, the sensitivity and specificity estimates remained robust, with the highest at 59.6% (49.7%;69.1%) and 88.6% (87.6%;89.6%), respectively. The unadjusted prevalence estimates were consistently lower than the adjusted prevalence estimates for both epilepsy and WSCH. CONCLUSIONS/SIGNIFICANCE This study demonstrates that in some settings, the prevalence of epilepsy and WSCH can be considerably underestimated when using the two-step approach. We provide an analytic solution to obtain more valid prevalence estimates of these neurological disorders, although more community-based validity studies are needed to reduce the uncertainty of the estimates. Valid estimates of these two neurological disorders are essential to obtain accurate burden values for neglected tropical diseases such as neurocysticercosis that manifest as epilepsy or WSCH.

Treating People With Epilepsy in Rural Low-Income Countries Is Feasible. Observations and Reflections From a "Real Life Experience" After a Long Lasting Intervention in the Rural Chaco. Front Neurol 2018; 9:855. [PMID: 30364141 PMCID: PMC6191465 DOI: 10.3389/fneur.2018.00855] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2018] [Accepted: 09/21/2018] [Indexed: 01/20/2023] Open
Abstract
Introduction: Epilepsy represents an important public health issue, in particular in low and middle-income countries where significant disparities are present in the care available for patients with epilepsy. Treatment cost and unavailability of drugs represent important barriers in treating people with epilepsy especially in rural setting. Aim of the study was to evaluate, by means of routine data, the current real-life clinical practice in epilepsy in the rural communities of the Plurinational State of Bolivia. Treatment activity followed educational campaigns and an anthropological fieldwork over more than 20 years. Material and Methods: Medical records of people with epilepsy (PWE) living in the rural communities of the Bolivian Chaco who received antiepileptic drugs (AEDs), from 2012 to 2016, and were followed-up for at least 1 year were analyzed. Treatment delivery and follow up visits were managed by a neurologist with the support of rural health care workers. Results: From 2012 to 2016, 157 PWE (76 men with a mean age of 24.2 ± 15.7) have been included in the study. Structural epilepsy was the most common type, recorded in 54 cases (34.4%) and the most common reported causes were perinatal factors, present in 11 subjects (20.0%). Almost all patients presented epilepsy with generalized tonic-clonic seizures (91.4%). The most common AED prescribed was phenobarbital followed by carbamazepine. During the follow-up, a dramatic seizures reduction was observed, with 31 subjects (19.7%) being seizures-free at the last follow-up. However, 48 subjects (30.6%) did not assume the medication regularly and 10 interrupted the drug intake. More than 20% of PWE did not receive any financial supports for AEDs. During the follow-up period 10 patients died but only in one case the death was probably caused by epilepsy. Conclusion: Our study demonstrated that PWE in rural areas of the Bolivian Chaco are willing to seek medical attention and to receive antiepileptic treatment. However, improvement in care is needed to assure compliance to AED treatment, including activity to increase awareness toward epilepsy among community members and health staff of the rural communities and to guarantee the coverage of treatment costs and drug supply.

Abstract
INTRODUCTION Epilepsy represents a major global healthcare issue, particularly in low- and middle-income countries (LMIC), where nonmedical health workers play a key role in providing care to people with epilepsy (PWE). Over the last 20 years, many projects have been carried out by our group in the Chaco region, Plurinational State of Bolivia, with the aim of enhancing knowledge about epilepsy. However, the level of knowledge of epilepsy that nonmedical health workers have reached has never been assessed until now. The main objective of our study was to assess the level of knowledge, attitudes, and practices (KAP) towards epilepsy among nonmedical health staff of the rural communities of the Chaco region in Bolivia. METHODS The study was conducted in three departments of Bolivia. The nonmedical health personnel were invited to participate in a training program. They answered a validated questionnaire to evaluate their knowledge and attitudes towards epilepsy before and after the courses. RESULTS One hundred nineteen subjects [42 men (36.2%); mean age 29.3 ± 1.1 years] were interviewed among community health workers and nurses before the courses, demonstrating a very good level of knowledge regarding epilepsy and its causes. Only 55 health workers participated in the second training module, and their answer did not significantly differ from the baseline. CONCLUSION Our study confirms the usefulness of continuous educational campaigns, especially directed to nonspecialist healthcare providers of rural communities of LMIC, as they may be the only persons responsible for providing healthcare to PWE in that setting. Moreover, the importance of the baseline assessment of KAP was highlighted in order to adapt the educational campaigns to the baseline level of knowledge found.
