Prevalence and factors associated with depressive symptoms among patients with epilepsy in Ethiopia: a national-based systematic review and meta-analysis. Front Neurol 2024; 15:1352648. [PMID: 38500809 PMCID: PMC10946423 DOI: 10.3389/fneur.2024.1352648] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Accepted: 02/15/2024] [Indexed: 03/20/2024] Open
Abstract
Background Depression is a major public health problem and negatively affects the quality of life of patients with epilepsy. Despite multiple studies investigating the magnitude and predictors, the results have been inconsistent. Therefore, this study aimed to estimate the pooled prevalence and factors associated with depressive symptoms among patients with epilepsy in Ethiopia. Methods The primary articles were searched using databases like PubMed, Google Scholar, CINAHL, SCOPUS, EMBASE, and African Journal Online. A total of 10 primary articles that assessed the prevalence and factors associated with depressive symptoms among patients with epilepsy in Ethiopia were included. A Microsoft Excel spreadsheet was used to extract the data, which was then exported to Stata version 14 for further analysis. The statistical heterogeneity was evaluated using the I2 test. Due to heterogeneity, a random effect meta-analysis model was employed. Publication bias was checked through Egger's weighted regression test and funnel plot. Results A total of 10 primary studies with 3,532 participants were included. The pooled prevalence of depressive symptoms among patients with epilepsy was found to be 41.69% (95% CI, 37.70, 45.68). The pooled prevalence of depressive symptoms was 48.61, 42.98, 40.68, 38.27, and 34.80% in Oromia, SNNPs, Amhara, Addis Ababa, and Tigray, respectively, based on a sub-group analysis per regional state. Perceived stigma (AOR = 3.30, 95% CI: 1.40, 7.80), seizure frequency (AOR = 3.81, 95% CI: 1.03, 14.09), and perceived stress (AOR = 4.6, 95% CI: 1.05, 20.06) were factors associated with depressive symptoms. Conclusion We found that depressive symptoms affects at least four out of ten patients with epilepsy, indicating an immense burden. Depressive symptoms were extremely prevalent in those who had high levels of stigma, a monthly seizure frequency of once or more, and perceived stress. Therefore, physicians should take extra precautions when treating patients with epilepsy who have certain conditions. Systematic review registration This study was registered according to The International Prospective Register of Systemic Review (PROSPERO) with the registration ID (CRD42023484308).

Abstract
Objectives Epilepsy is a common neurological condition in low- and middle-income countries (LMICs). This study aims to systematically review, analyze, evaluate, and synthesize information on the current state of medical and surgical management and outcomes of epilepsy in LMICs. Materials and Methods Systematic searches were conducted on MEDLINE, EMBASE, World Health Organization Global Index Medicus, African Journals Online, WOS, and Scopus, covering the period from the inception of the databases to August 18th, 2021, focusing on studies reporting management and outcomes of epilepsy in LMICs. Results A total of 2298 unique studies were identified, of which, 48 were included (38035 cases). The mean age was 20.1 ± 19.26 years with a male predominance in 60.92% of cases. The type of seizure commonly reported in most of the studies was absence seizures (n = 8302, 21.82%); partial focal seizure (n = 3891, 10.23%); and generalized tonic-clonic seizures (n = 3545, 9.32%) which were the next most common types of seizures. Mesiotemporal epilepsy was less frequently reported (n = 87, 0.22%). Electroencephalogram was commonly used (n = 2516, 6.61%), followed by computed tomography scan (n = 1028, 2.70%), magnetic resonance imaging (n = 638, 1.67%), and video telemetry (n = 484, 1.27%) in the care of patients with seizures. Primary epilepsy was recorded in 582 patients (1.53%) whereas secondary epilepsy was present in 333 patients (0.87%). Carbamazepine was the most used anti-epileptic drug (n = 2121, 5.57%). Surgical treatment was required for 465 (1.22%) patients. Conclusion In LMICs, epilepsy is underreported. There is still a lack of adequate tools for the diagnosis of primary or secondary epilepsy as well as adequate access to medical management of those reported.

Abstract
Manifestation of abnormal excessive synchronous cortical activity, which is what defines epileptic seizures, is typically absent in seizures with psychological etiology, a heterogeneous set of factors that have been identified. Distinguishing psychogenic nonepileptic seizures (PNES) from epileptic seizures may be difficult at the bedside. We report a case series of PNES which presented with diagnostic dilemma. Diagnostic delay of years with PNES is common. The exact choice of treatment is often difficult and should be based on individual differences in the underlying factors. Outcome can be measured in terms of seizure occurrence (frequency, severity), but other measures might be of greater importance for the patient. Prognosis is varied but studies consistently report that 1/3rd to 1/4th of these cases become chronic.

A Physiologically Based Pharmacokinetic Model for Predicting Diazepam Pharmacokinetics after Intravenous, Oral, Intranasal, and Rectal Applications. Pharmaceutics 2021; 13:pharmaceutics13091480.

Abstract
Diazepam is one of the most prescribed anxiolytic and anticonvulsant that is administered through intravenous (IV), oral, intramuscular, intranasal, and rectal routes. To facilitate the clinical use of diazepam, there is a need to develop formulations that are convenient to administer in ambulatory settings. The present study aimed to develop and evaluate a physiologically based pharmacokinetic (PBPK) model for diazepam that is capable of predicting its pharmacokinetics (PK) after IV, oral, intranasal, and rectal applications using a whole-body population-based PBPK simulator, Simcyp®. The model evaluation was carried out using visual predictive checks, observed/predicted ratios (Robs/pred), and the average fold error (AFE) of PK parameters. The Diazepam PBPK model successfully predicted diazepam PK in an adult population after doses were administered through IV, oral, intranasal, and rectal routes, as the Robs/pred of all PK parameters were within a two-fold error range. The developed model can be used for the development and optimization of novel diazepam dosage forms, and it can be extended to simulate drug response in situations where no clinical data are available (healthy and disease).

Purinergic Signal 2021; 17:533-548. [PMID: 34495463 DOI: 10.1007/s11302-021-09818-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Accepted: 08/08/2021] [Indexed: 11/29/2022] Open
Abstract
Purinergic signaling mediated by ATP and its metabolites contributes to various brain physiological processes as well as to several pathological conditions, including neurodegenerative and neurological disorders, such as epilepsy. Among the different ATP release pathways, pannexin 1 channels represent one of the major conduits being primarily activated in pathological contexts. Investigations on in vitro and in vivo models of epileptiform activity and seizures in mice and human tissues revealed pannexin 1 involvement in aberrant network activity and epilepsy, and highlighted that pannexin 1 exerts a complex role. Pannexin 1 can indeed either sustain seizures through release of ATP that can directly activate purinergic receptors, or tune down epileptic activity via ATP-derived adenosine that decreases neuronal excitability. Interestingly, in-depth analysis of the literature unveils that this dichotomy is only apparent, as it depends on the model of seizure induction and the type of evoked epileptiform activity, two factors that can differentially activate pannexin 1 channels and trigger distinct intracellular signaling cascades. Here, we review the general properties and ATP permeability of pannexin 1 channels, and discuss their impact on acute epileptiform activity and chronic epilepsy according to the regime of activity and disease state. These data pave the way for the development of new antiepileptic strategies selectively targeting pannexin 1 channels in a context-dependent manner.

Chem Biol Interact 2021; 340:109447.

Abstract
Accumulating evidences indicate that thiamine plays a vital role in the nervous system. However, questions exist as to how it causes epilepsy, neuronal damage, and antiepileptic mechanisms. The study looked at how the thiamine supplement impacted pentylenetetrazole (PTZ)-induced seizures in rats and pentylenetetrazole-induced neurotoxicity in the SH-SY5Y cell line. We used twenty-four male rats and they were randomly divided into 4 groups as control, saline (1 mL/kg/day serum physiologic) + PTZ, thiamine (50 mg/kg/day) + PTZ, and thiamine (50 mg/kg/day) for 10 days. PTZ (45 mg/kg) was given to activate the seizure on day 10. Memory efficiency was measured by using passive avoidance. The brain levels of 8-hydroxy-2'-deoxyguanosine (8-OHdG), caspase-3, nitric oxide (NO), and cyclic guanosine monophosphate (cGMP) were analyzed by using ELISA kits. SH-SY5Y cells were treated with/without thiamine for 1 h, followed by PTZ (30 μm) at a medium level to trigger neurotoxicity. Cell viability, total antioxidant status, total oxidant status, and apoptosis were assayed in the SH-SY5Y cells. Thiamine delayed the initiation of epileptic seizures and increased memory damage. In addition, 8-OHdG, caspase-3, NO, and cGMP levels were significantly reduced in the brain and prevented pentylenetetrazole-induced neurotoxicity, apoptosis, enhanced antioxidant, and reduced oxidant in SH-SY5Y cells. Thiamine dramatically altered seizures, memory loss, oxidative stress, and apoptosis. Thiamine has a preventative effect on PTZ-induced seizures in rats and PTZ-induced neurotoxicity in SH-SY5Y neuroblastoma cells. It could prevent oxidative stress and signaling of NO/cGMP. Thiamine supplement could be used as an additional therapeutic agent in epilepsy.

Abstract
Recent studies have shown that natural antioxidant compounds have positive effects on the nervous system. Lycopene, the red pigment in tomatoes, is one of the potent natural antioxidants, and is used as supplementation because of its well-known health benefits. However, its effect on epileptic seizures and underlying mechanisms are still unclear. In this study, it was aimed to investigate the effect of lycopene on pentylenetetrazole-induced epileptic seizures in rats and to elucidate the nitric oxide pathway in this effect. In this study, thirty male Wistar albino rats were used. Animals were divided into five groups (n = 6 for each group) as control, saline (1 mL/kg/day serum physiologic), positive control (2 mg/kg/day diazepam), and lycopene (5 and 10 mg/kg/day) for ten days. Pentylenetetrazole (45 mg/kg) was given to induce a seizure in the tenth day except for the control. Passive avoidance test was carried out to evaluate memory function. Inducible nitric oxide synthase (iNOS), neuronal nitric oxide synthase (nNOS), and nitric oxide (NO) levels were measured in the cortex and hippocampal brain regions using the ELISA kits. Lycopene supplementation prolonged epileptic seizure onset times and reduced seizure stages. Besides, lycopene supplementation improved memory impairment after seizures. Moreover, lycopene significantly reduced the level of iNOS, nNOS, and NO in the brain. Lycopene supplementation significantly alleviated seizures and memory impairment. Its anticonvulsive effect could be associated with the nitric oxide pathway. Lycopene supplementation could be useful as a supportive therapeutic agent in epileptic patients.

Abstract
Benzodiazepines such as diazepam, lorazepam and midazolam remained the mainstay of treatment for acute repetitive seizures (ARS). The immediate care for ARS should often begin at home by a caregiver. This prevents the progression of ARS to prolonged seizures or status epilepticus. For a long time and despite social objections rectal diazepam gel remained only FDA-approved rescue medication. Intranasal administration of benzodiazepines is considered attractive and safe compared with rectal, buccal and sublingual routes. Intranasal delivery offers numerous advantages such as large absorptive surface area, bypass the first-pass metabolism and good patient acceptance as it is needle free and painless. Recent clinical studies have demonstrated that diazepam nasal spray (NRL-1; Valtoco®, Neurelis Inc.,San Diego, CA, USA) showed less pharmacokinetic variability and reliable bioavailability compared with the diazepam rectal gel. Diazepam nasal spray could be considered as a suitable alternative for treating seizure emergencies outside the hospital. This review summarizes the treatment options for ARS and findings from clinical studies involving intranasal diazepam for treating seizure emergencies.

Abstract
INTRODUCTION A higher rate of subtherapeutic psychotropic drug concentrations was recently found in HIV-infected versus HIV-negative patients. In this study, we sought to investigate if this trend could also apply to antiepileptic drugs. METHODS Overall, 700 HIV-infected patients were screened during the first 2 years after the introduction of our outpatient polytherapy management service (Gestione Ambulatoriale Politerapie [GAP]) in the search for subjects with antiepileptic drug trough concentration assessments. The distribution of such concentrations was compared with that in HIV-negative patients monitored over the same period. RESULTS The search identified 97 HIV-infected patients concomitantly receiving antiretroviral and antiepileptic drugs, for a total of 310 drug measurements. Overall, 30%, 64% and 6%, versus 28%, 65% and 7%, of the antiepileptic concentrations measured in HIV-infected versus HIV-negative patients (1090 patients, for a total of 3488 antiepileptic concentrations measured) were below, within, or above the therapeutic targets, respectively. The antiepileptic drug valproate was associated with the highest risk of subtherapeutic drug concentrations, with 57% and 46% of determinations below the therapeutic range in HIV-positive and HIV-negative patients, respectively. Remarkably, the concentrations of valproate were significantly lower in HIV-infected versus HIV-negative patients (47.9 ± 21.2 versus 53.9 ± 21.6 mg/L; p < 0.05). CONCLUSION In our retrospective study, most HIV-infected patients had antiepileptic drug concentrations falling within the therapeutic targets, with the exception of valproate, which was associated with a higher rate of subtherapeutic concentrations compared with other antiepileptic drugs.

Abstract
Efficacy and safety of the combination of magnesium sulfate, phentolamine and nifedipine in the treatment of patients with hypertensive disorder complicating pregnancy (HDCP) and its effect on hemodynamics and urinary protein level were investigated. One hundred and six patients with HDCP diagnosed at the Affiliated Hospital of Beihua University from February 5, 2016 to May 9, 2017 were retrospectively analyzed. Patients were divided into the magnesium sulfate group and the combination group, according to the therapeutic schemes. The efficacy 1 week later was observed. The general clinical data of the patients were recorded, and data were acquired with respect to hemodynamic indexes before and after treatment [changes of S/D ratio of umbilical artery flow, and cardiac index and total peripheral resistance (TPR)], the 24-h urinary protein level, clinical efficacy and safety [adverse drug reactions (ADR) and maternal and neonatal outcomes]. Before treatment, there was no statistically significant difference between the two groups in terms of S/D ratio of umbilical artery flow (P>0.05), while after treatment the S/D ratio was significantly lower than that before treatment in both groups (P<0.05). Before treatment, there was no statistically significant difference between the two groups in terms of cardiac index (P>0.05). TPR after treatment was significantly lower than that before treatment in both groups (P<0.001). Compared with the magnesium sulfate group, patients in the combination group had significantly lower 24-h urinary protein level after treatment (P<0.001), significantly higher total effective rate (P<0.05), significantly lower incidence rate of ADR (P<0.001), and significantly lower incidence rate of adverse maternal and neonatal outcomes (P<0.001). In conclusion, the combination of magnesium sulfate, phentolamine and nifedipine can significantly improve the hemodynamic indexes, the 24-h urinary protein level, the clinical efficacy, ADR and maternal and neonatal outcomes of patients with HDCP, therefore it is worthy of use in the clinic.

Abstract
Epilepsy is a serious neurological disorder and is characterized by recurrent and unprovoked seizures. A critical pathological factor in the seizure genesis is neuronal loss. Until now, apart from the known regulatory cell death pathways, ferroptosis is a newly discovered type of cell death with the features of iron accumulation and the excessive production of lipid reactive oxygen species (ROS). In our present work, it was illustrated that ferroptosis occurs in murine models of pentylenetetrazole (PTZ) kindling and pilocarpine (Pilo)-induced seizures. In both of these seizure models, treatment with ferroptosis inhibitor ferrostatin-1 (Fer-1) efficiently alleviates seizures. This was achieved through elevated levels of glutathione peroxidase 4 (GPX4) and glutathione (GSH) as well as inhibitions of lipid degradation products including 4-hydroxynonenal (4-HNE) and malonaldehyde (MDA), iron accumulation, and PTGS2 mRNA in the hippocampus. It was concluded that ferroptosis is involved in seizure genesis in PTZ- and Pilo-treated mice, while the suppression of ferroptosis mitigates PTZ kindling, and Pilo-induced seizures in mice.

[PMID: 31211023 PMCID: PMC6557303 DOI: 10.7717/peerj.7115] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2019] [Accepted: 05/10/2019] [Indexed: 01/07/2023] Open
Abstract
Background Epilepsy during pregnancy presents a unique set of challenges for pregnant women, the fetus, and the health care community. As research in this area advances rapidly, it is critical to keep up with the emerging trends and key turning points of the development of the domain knowledge. This study aimed to construct a series of science maps to quantitatively and qualitatively evaluate the intellectual landscape and research frontiers in the field of epilepsy during pregnancy research. Methods All publications were extracted from the Web of Science Core Collection database. Bibliometric analysis was used to analyze the scientific research outputs, including journals, countries/regions, institutions, authors (cited authors), intellectual base and research hotspots. Results A total of 2,225 publications related to epilepsy during pregnancy were identified as published between 2000 and 2018. The overall trend of the number of publications showed a fluctuating growth from 59 articles in 2000 to 198 in 2018. Neurology was the leading journal in the field of epilepsy and pregnancy research both in terms of impact factor score (8.055) and H-index value (77). The US retained its leading position and exerted a pivotal influence in this area. The University of Melbourne was identified as a good research institution for research collaboration. Prof. Pennell and Tomson have made great achievements in this area, and Prof. Tomson laid a foundation for the development of this domain. The keyword “neonatal seizures” ranked first in research hotspots, and the keyword “autism spectrum disorders (ASD)” ranked first in research frontiers. Conclusions Epilepsy during pregnancy is a fascinating and rapid development of subject matter. A more recent emerging trend focused on comprehensive management of pregnant and lactating women, evaluation of the safety and efficacy of newer antiepileptic drugs. The keywords “management issue,” “brain injury,” “meta-analysis,” “in utero exposure,” and “ASD” were the latest research frontiers and should be closely observed.

Zaporojan L, McNamara PH, Williams JA, Bergin C, Redmond J, Doherty CP. Seizures in HIV: The case for special consideration. EPILEPSY & BEHAVIOR CASE REPORTS 2018; 10:38-43. [PMID: 30013932 PMCID: PMC6022180 DOI: 10.1016/j.ebcr.2018.02.006] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/11/2017] [Revised: 02/13/2018] [Accepted: 02/26/2018] [Indexed: 12/21/2022]
Abstract
Purpose This study aimed to determine the rate, cause and management of seizures in the context of potential ART–ASD interactions in a cohort of HIV + individuals. Methods Records of 604 HIV + patients were reviewed and those reporting epilepsy/seizure diagnosis were further evaluated. Results This cohort exhibited a seizure rate of 2.4%. HIV + patients treated for epilepsy displayed low serum ASD levels and failed to achieve seizure control. They were more likely to disengage from Neurology follow-up. Conclusion For HIV + patients presenting with seizures/epilepsy the ASD prescription and the provision of supplementary support services needs to be carefully considered. ID and Neurology services should be involved in the evaluation and treatment of seizures in the context of HIV infection. ART-ASD interactions could have been the cause of ineffective treatment and other poor outcomes in this small cohort. In this group of patients it is important to apply published guidelines when it comes to making treatment decisions. Counseling and supportive services need to be provided to ensure engagement with services and adherence to treatment.
