Electroencephalographic Findings, Antiepileptic Drugs and Risk Factors of 433 Individuals Referred to a Tertiary Care Hospital in Ethiopia

Background

Little is known about the characteristics of electroencephalogram (EEG) findings in epileptic patients in Ethiopia. The objective of this study was to characterize the EEG patterns, indications, antiepileptic drugs (AEDs), and epilepsy risk factors.

Methods

A retrospective observational review of EEG test records of 433 patients referred to our electrophysiology unit between July 01, 2020 and December 31, 2021.

Results

The age distribution in the study participants was right skewed unipolar age distribution for both sexes and the mean age of 33.8 (SD=15.7) years. Male accounted for 51.7%. Generalized tonic clonic seizure was the most common seizure type. The commonest indication for EEG was abnormal body movement with loss of consciousness (35.2%). Abnormal EEG findings were observed in 55.2%; more than half of them were Interictal epileptiform discharges, followed by focal/or generalized slowing. Phenobarbitone was the commonest AEDs. A quarter (20.1%) of the patients were getting a combination of two AEDs and 5.2% were on 3 different AEDs. Individuals taking the older AEDs and those on 2 or more AEDs tended to have abnormal EEG findings. A cerebrovascular disorder (27.4%) is the prevalent risk factor identified followed by brain tumor, HIV infection, and traumatic head injury respectively.

Conclusions

High burden of abnormal EEG findings among epileptic patients referred to our unit. The proportion of abnormal EEG patterns was higher in patients taking older generation AEDs and in those on 2 or more AEDs. Stroke, brain tumor, HIV infection and traumatic head injury were the commonest identified epilepsy risk factors.

Perceptions Regarding the SARS-CoV-2 Pandemic's Impact on Neurocritical Care Delivery: Results From a Global Survey

BACKGROUND

The SARS-CoV-2 (COVID-19) pandemic has impacted many facets of critical care delivery.

METHODS

An electronic survey was distributed to explore the pandemic's perceived impact on neurocritical care delivery between June 2020 and March 2021. Variables were stratified by World Bank country income level, presence of a dedicated neurocritical care unit (NCCU) and experiencing a COVID-19 patient surge.

RESULTS

Respondents from 253 hospitals (78.3% response rate) from 47 countries (45.5% low/middle income countries; 54.5% with a dedicated NCCU; 78.6% experienced a first surge) participated in the study. Independent of country income level, NCCU and surge status, participants reported reductions in NCCU admissions (67%), critical care drug shortages (69%), reduction in ancillary services (43%) and routine diagnostic testing (61%), and temporary cancellation of didactic teaching (44%) and clinical/basic science research (70%). Respondents from low/middle income countries were more likely to report lack of surge preparedness (odds ratio [OR], 3.2; 95% confidence interval [CI], 1.8-5.8) and struggling to return to prepandemic standards of care (OR, 12.2; 95% CI, 4.4-34) compared with respondents from high-income countries. Respondents experiencing a surge were more likely to report conversion of NCCUs and general-mixed intensive care units (ICUs) to a COVID-ICU (OR 3.7; 95% CI, 1.9-7.3), conversion of non-ICU beds to ICU beds (OR, 3.4; 95% CI, 1.8-6.5), and deviations in critical care and pharmaceutical practices (OR, 4.2; 95% CI 2.1-8.2). Respondents from hospitals with a dedicated NCCU were less likely to report conversion to a COVID-ICU (OR, 0.5; 95% CI, 0.3-0.9) or conversion of non-ICU to ICU beds (OR, 0.5; 95% CI, 0.3-0.9).

CONCLUSION

This study reports the perceived impact of the COVID-19 pandemic on global neurocritical care delivery, and highlights shortcomings of health care infrastructures and the importance of pandemic preparedness.

Regional and national differences in stroke thrombolysis use and disparities in pricing, treatment availability and coverage

BACKGROUND

Major disparities have been reported in recombinant tissue Plasminogen Activator (rtPA) availability among countries of different socioeconomic status.

AIMS

To characterize variability of rtPA price, its availability, and its association with and impact on each country's health expenditure (HE) resources.

METHODS

We conducted a global survey to obtain information on rtPA price (50mg vial, 2020 US Dollars) and availability. Country-specific data, including Low, Lower Middle (LMIC), Upper Middle (UMIC) and High-Income Country (HIC) classifications, and Gross Domestic Product (GDP) and HE, both nominally and adjusted for purchasing power parity (PPP), were obtained from World Bank Open Data. To assess the impact of rtPA cost, we computed the rtPA price as percentage of per capita GDP and HE and examined its association with the country income classification.

RESULTS

rtPA is approved and available in 109 countries. We received surveys from 59 countries: 27 (46%) HIC, 20 (34%) UMIC and 12 (20%) LMIC. Although HIC have significantly higher per capita GDP and HE compared to UMIC and LMIC (p<0.0001), the median price of rtPA is non-significantly higher in LMICs [USD 755, IQR (575-1300)] compared to UMICs [USD 544, IQR (400-815)] and HIC [USD 600, IQR (526-1000)]. In LMIC, rtPA cost accounts for 217.4% (IQR (27.1-340.6%) of PPP-adjusted per capita HE, compared to 17.6% (IQR [11.2-28.7%], p<0.0001) for HICs.

CONCLUSIONS

We documented significant rtPA availability and variability in its price among countries. Relative costs are higher in lower income countries, exceeding the available HE. Concerted efforts to improve rtPA affordability in low-income settings are necessary.

Stroke services in Africa: What is there and what is needed

BACKGROUND

Over the past few years, the incidence and prevalence of stroke has been rising in most African countries and has been reported as one of the leading causes of morbidity and mortality. To study this problem, we need to realize the quality and availability of stroke care services as a priori to improve them.

METHODS AND RESULTS

In this study, we investigated the availability of different stroke-related services in 17 countries from different African regions. An online survey was conducted and fulfilled by stroke specialists and included primary prevention, acute management, diagnostic tools, medications, postdischarge services, and stroke registries. The results showed that although medications for secondary prevention are available, yet many other services are lacking in various countries.

CONCLUSION

This study displays the deficient aspects of stroke services in African countries as a preliminary step toward active corrective procedures for the improvement of stroke-related health services.

Antiepileptic Drug Treatment Outcomes and Seizure-Related Injuries Among Adult Patients with Epilepsy in a Tertiary Care Hospital in Ethiopia

Objective

Anti-epileptic drugs (AEDs) are the primary therapeutic modalities for epilepsy management. However, one-third of epileptic patients continue to experience seizure even with appropriate AED use. Patients with epilepsy are at increased risk for seizure-related injury and they have higher incidences of home, street and work accidents. There is a paucity of data on AED use pattern and treatment outcomes among patients with epilepsy in the tertiary hospitals of Ethiopia. Therefore, the aim of this study was to assess AED use pattern, treatment outcome, and prevalence of seizure-related injury among patients with epilepsy in Tikur Anbessa specialized Hospital (TASH), Ethiopia.

Patients and Methods

An institution-based cross-sectional study was carried out on 291 patients with epilepsy attending the neurology clinic of TASH. A semi-structured questionnaire and data abstraction format were used to collect data through patient interview and medical chart review. Binary logistic regression was utilized to identify the associated factors of treatment outcome.

Results

About 172 (59%) of the patients were taking a single AED, in which phenobarbital, 195 (67%), and phenytoin, 97 (33.3%), were the most frequently prescribed AEDs as monotherapy and combination therapy. Headache, depressed mood and epigastric pain were frequently reported as adverse drug reactions. Seizure-related injury was reported among 78 (26.8%) patients and head injury 15 (5.2%), desntal injury 15 (5.2%), soft tissue injury 14 (4.8%) and burns 10 (3.4%) were the commonest. About two-thirds (191, 65.6%) of the study participants had uncontrolled seizure. Medication adherence and multiple AEDs were significantly associated with treatment outcome.

Conclusion

All the study participants were put on old generation AEDs with phenobarbital being the most frequently used. About two-thirds of the patients had uncontrolled seizure and seizure-related injury is still a serious concern among patients with epilepsy.

Drug therapy problems and treatment satisfaction among ambulatory patients with epilepsy in a specialized hospital in Ethiopia

Objective

Epilepsy management especially in developing country is challenging. Seizures recurrence can be caused by both drug and non-drug related problems such as inadequate antiepileptic regimens, adverse drug reaction and poor adherence. Patient treatment satisfaction also affects the treatment out comes by improving medication adherence. This study aimed to assess drug therapy problems (DTPs) and treatment satisfaction among ambulatory epileptic patients at Tikur Anbessa Specialized Hospital.

Methods

A prospective cross-sectional study was conducted on 291 epileptic patients. Data was collected through patient interview and medical charts review. DTPs were identified based on the standard treatment guidelines and Micromedex® was used as drug interaction checker. Cipolle DTPs classification was used to classify the DTPs and Treatment Satisfaction with Medicine Questionnaire (SATMED-Q) was used to assess treatment satisfaction. Binary logistic regressions were utilized to identify the associated factors.

Results

Phenobarbital 195 (67%) and phenytoin 97 (33.3%) were the most frequently prescribed antiepileptic medications as monotherapy or combination therapy. Only 54 (18.6%) of the study participants had controlled seizure. DTP was found in 205(70.4%) of the study participants. From 352 DTPs identified, adverse drug reaction 146 (41.5%) was the leading DTPs followed by ineffective drugs 98 (27.8%) drug interaction 45 (12.8%) and inappropriate dose 42(11.9%). Headache, depression and epigastric pain were frequently reported adverse drug reaction. Among the study participants 167 (57.3%) were adherent to their medications. The number of medications taken by the patients had significant association with occurrence of DTPs, whereas source of medication and seizure free periods were found to have significant association with poor adherence. The global patient satisfaction was (67.4%) and lower satisfaction rate was found with regard to impact on daily activities (62.0%), treatment effectiveness (64.7%) and medical care (65.9%).

Conclusion

Prevalence of DTPs among ambulatory epileptic patients was high and about half of the patients were nona-dherent for their medication. The overall treatment satisfaction of the patients was suboptimal.

Ethiopian teachers: their knowledge, attitude and practice towards epilepsy

BACKGROUND

In Ethiopia where the burden of epilepsy is highest among school age children and teenagers, and where people with epilepsy (PWE) and their relatives suffers from high level of perceived stigma, there had not been any study that assessed the knowledge, attitude and practice of teachers towards PWE. This study aims to assess and understand the social and demographic determinants of knowledge, attitude and practice of teachers towards PLW in Addis Ababa, Ethiopia.

METHODS

Multistage cluster sampling procedure was used to identify twenty schools from three sub cities of Addis Ababa, Ethiopia. Standardized self administered questionnaire was used to collect data from 845 volunteer teachers in the pre identified schools. Frequencies were used to characterize the demographic variables while multiple response frequencies were used to characterize the multiple response variable sets. Non-parametric statistical methods were used to describe the association among the demographic variables of interest and the count sums of multiple response variables which were grouped into biologically and culturally plausible responses.

RESULTS

The most common biologically plausible responses were: brain diseases (26.5 %) from causes, allow my offspring to play with PWE (19.1 %) from attitude, protect the subject from injury (20.4 %) from first aid measures and seek help from medical doctors (52.2 %) from epilepsy treatment. On the contrary, the most common culturally plausible responses were: psychiatric illness (12.9 %) from causes, epilepsy be cured before attendance to school (21.6 %) from attitude, smelling the smoke of struck match (14.2 %) from first aid measures and Holy water treatment (20.3 %) from epilepsy treatment suggestions. The biologically and culturally plausible responses were negatively correlated. Level of education was positively associated with biologically plausible responses while teaching experience was negatively correlated with culturally plausible responses.

CONCLUSION

A high percentage of teachers in Addis Ababa considered epilepsy as a psychiatric illness closely linked to insanity. This explains their suggestions of Holy water treatment and Church healing sessions as epilepsy remedies. This is in agreement with Ethiopian culture, in which evil spirit and insanity are believed to be better treated by religious remedies than with modern medical treatments. Incorporating special needs educational training courses in the curriculum of teachers training may help them shift their knowledge, attitudes and practices from that of the culturally plausible to biologically plausible one.

Impact of an educational comic book on epilepsy-related knowledge, awareness, and attitudes among school children in Ethiopia

INTRODUCTION

Epilepsy is of worldwide public health importance because it is common, often accompanied by physical and cognitive disabilities, and is widely stigmatized. The incidence of epilepsy in Ethiopia was reported to be 64/100,000 population and a prevalence of 520/100,000 population. A minority of subjects is treated, and religious and sociocultural beliefs influence the nature of treatment and care. One approach to support the development of positive attitudes toward individuals with disabilities is through the use of comics. Comics have been effective in creating awareness and educating about epilepsy.

MATERIAL AND METHODS

We conducted a cross-sectional study among randomly selected students from two preparatory schools (one from a city and the other from a rural area) in June 2014. We collected information using a structured KAP questionnaire before and after reading a comic book. The comic book relevance was assessed by 40 health professionals.

RESULT

One hundred sixteen students from urban and 110 from rural high schools were enrolled in the present study with an age distribution of 31.9% in 16-17years, 48.7% in 18-19years, and 19.5% in 20+years. Thirty percent of the urban school was male compared with sixty-five percent of the rural school. The comic book was recommended as useful educational material to be distributed among school children by 90% of interviewed health professionals (internists, neurologist, psychiatrists, residents, GPs, and nurses).

CONCLUSION

The comic book was appreciated by the Ethiopian high school students. After brief exposure to the comic book, students could extract a great deal of information, it could change misconceptions and provide correct information about epilepsy, and can be an effective approach to epilepsy awareness creation. Health professionals found the comic book to be very informative and recommended its distribution to students, teachers, nurses, libraries, and community/religious leaders. Illustrations were Ethiopian-oriented.
