Efficacy and safety of corticosteroids and ACTH in epileptic syndromes beyond Infantile Epileptic Spasms Syndrome (IESS): A systematic review and meta-analysis. Epilepsia 2024; 65:1155-1175. [PMID: 38411568 DOI: 10.1111/epi.17918] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Revised: 02/02/2024] [Accepted: 02/02/2024] [Indexed: 02/28/2024]
Abstract
We conducted a systematic review investigating the efficacy and tolerability of adrenocorticotropic hormone (ACTH) and corticosteroids in children with epilepsies other than infantile epileptic spasm syndrome (IESS) that are resistant to anti-seizure medication (ASM). We included retrospective and prospective studies reporting on more than five patients and with clear case definitions and descriptions of treatment and outcome measures. We searched multiple databases and registries, and we assessed the risk of bias in the selected studies using a questionnaire based on published templates. Results were summarized with meta-analyses that pooled logit-transformed proportions or rates. Subgroup analyses and univariable and multivariable meta-regressions were performed to examine the influence of covariates. We included 38 studies (2 controlled and 5 uncontrolled prospective; 31 retrospective) involving 1152 patients. Meta-analysis of aggregate data for the primary outcomes of seizure response and reduction of electroencephalography (EEG) spikes at the end of treatment yielded pooled proportions (PPs) of 0.60 (95% confidence interval [CI] 0.52-0.67) and 0.56 (95% CI 0.43-0.68). The relapse rate was high (PP 0.33, 95% CI 0.27-0.40). Group analyses and meta-regression showed a small benefit of ACTH and no difference between all other corticosteroids, a slightly better effect in electric status epilepticus in slow sleep (ESES) and a weaker effect in patients with cognitive impairment and "symptomatic" etiology. Obesity and Cushing's syndrome were the most common adverse effects, occurring more frequently in trials addressing continuous ACTH (PP 0.73, 95% CI 0.48-0.89) or corticosteroids (PP 0.72, 95% CI 0.54-0.85) than intermittent intravenous or oral corticosteroid administration (PP 0.05, 95% CI 0.02-0.10). The validity of these results is limited by the high risk of bias in most included studies and large heterogeneity among study results. This report was registered under International Prospective Register of Systematic Reviews (PROSPERO) number CRD42022313846. We received no financial support.

Efficacy and Safety of Pulse Intravenous Methylprednisolone in Pediatric Epileptic Encephalopathies: Timing and Networks Consideration. J Clin Med 2024; 13:2497. [PMID: 38731025 PMCID: PMC11084200 DOI: 10.3390/jcm13092497] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2024] [Revised: 04/10/2024] [Accepted: 04/19/2024] [Indexed: 05/13/2024] Open
Abstract
Background: Epileptic encephalopathies (EE) are characterized by severe drug-resistant seizures, early onset, and unfavorable developmental outcomes. This article discusses the use of intravenous methylprednisolone (IVMP) pulse therapy in pediatric patients with EE to evaluate its efficacy and tolerability. Methods: This is a retrospective study from 2020 to 2023. Inclusion criteria were ≤18 years at the time of IVMP pulse therapy and at least 6 months of follow-up. Efficacy and outcome, defined as seizure reduction > 50% (responder rate), were evaluated at 6 and 9 months of therapy, and 6 months after therapy suspension; quality of life (QoL) was also assessed. Variables predicting positive post-IVMP outcomes were identified using statistical analysis. Results: The study included 21 patients, with a responder rate of 85.7% at 6 and 9 months of therapy, and 80.9% at 6 months after therapy suspension. Variables significantly predicting favorable outcome were etiology (p = 0.0475) and epilepsy type (p = 0.0475), with the best outcome achieved in patients with genetic epilepsy and those with encephalopathy related to electrical status epilepticus during slow-wave sleep (ESES). All patients evidenced improvements in QoL at the last follow-up, with no relevant adverse events reported. Conclusions: Our study confirmed the efficacy and high tolerability of IVMP pulse therapy in pediatric patients with EE. Genetic epilepsy and ESES were positive predictors of a favorable clinical outcome. QOL, EEG tracing, and postural-motor development showed an improving trend as well. IVMP pulse therapy should be considered earlier in patients with EE.

The Response of Synthetic Adrenocorticotropic Hormone (ACTH) Treatment in Pediatric Drug-Resistant Epilepsy Other Than Infantile Epileptic Spasms Syndrome: A Retrospective Observational Study. Cureus 2023; 15:e46431. [PMID: 37927737 PMCID: PMC10621999 DOI: 10.7759/cureus.46431] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/28/2023] [Indexed: 11/07/2023] Open
Abstract
INTRODUCTION Adrenocorticotropic hormone (ACTH) is a tropic hormone naturally secreted by the anterior pituitary gland to stimulate the secretion of cortisol and androgens. ACTH is used in non-tuberous sclerosis infantile epileptic spasms syndrome (IESS), and it has shown significant, promising results in epilepsy syndromes with possible inflammatory processes. However, many studies have also demonstrated a promising potential even in other types of drug-resistant epilepsy. Material and method: This study is a retrospective observational study that follows the clinical characteristics and outcomes of nine pediatric patients with drug-resistant epilepsy treated with short-term synthetic ACTH in Saudi Arabia. The response was assessed during the ACTH infusion and after three months. RESULTS During infusion, six of the nine (66%) patients had a short-term (within two weeks) favorable response, with a more than 50% reduction in seizure frequency. Four of the nine (44%) patients had complete responses with seizure freedom. After three months, four patients (44%) had a three-month seizure frequency reduction of more than 30% attributed to ACTH, including one patient with an IESS history who had a 70% reduction in seizure frequency. Of the four patients who had a complete response, three (75%) had a seizure relapse after tapering in the following three months. Conclusion: This case series adds to the literature to suggest ACTH treatment of drug-resistant epilepsies other than IESS might benefit some patients in the acute setting but they are less likely to maintain a sustained treatment response. Randomized and large sample size studies are necessary to assess treatment response and accurately aid in appropriate patient selection.

Abstract
Background Adrenocorticotropic hormone therapy for infantile spasms, including West syndrome, has been previously reported to induce seizures. We present the findings for a school-aged child with epilepsy who developed new focal seizures during adrenocorticotropic hormone therapy. Case presentation The Japanese patient had posttraumatic epilepsy and developed intractable focal seizures at the age of 13 years. Adrenocorticotropic hormone therapy was administered when the patient was 14 years of age. On day 10 of treatment, he developed new focal seizures, which were characterized by left arm contractions followed by movements of touching things with his right hand and writhing and rocking his body left and right and back and forth as automatisms. The focal seizures clustered for 40 minutes and disappeared after suppository administration of 10 mg diazepam. These focal seizures did not reoccur after more than 2 years of follow-up. Conclusion Adrenocorticotropic hormone-induced seizures can occur in children older than previously reported, and can occur in children with intractable seizures other than epileptic spasms.

Abstract
The transdermal route of administration of drug substances allows clinicians to obtain a therapeutic effect bypassing the gastrointestinal tract, where the active substance could be inactivated. The hormonal substance used in the study-corticotropin (ACTH)-shows systemic effects. Therefore, the study of the effect of the type of ointment base and drug concentration on the release rate and also permeation rate in in vivo simulated conditions may be a valuable source of information for clinical trials to effectively optimize corticotropin treatment. This goal was achieved by preparation ointment formulation selecting the appropriate ointment base and determining the effect of ACTH concentration on the release and permeation studies of the ACTH. Semi-solid preparations containing ACTH were prepared using Unguator CITO e/s. The release study of ACTH was tested using a modified USP apparatus 2 with Enhancer cells. The permeation study was conducted with vertical Franz cells. Rheograms of hydrogels were made with the use of a universal rotational rheometer. The dependence of the amount of released and permeated hormone on the ointment concentration was found. Based on the test of ACTH release from semi-solid formulations and evaluation of rheological parameters, it was found that glycerol ointment is the most favourable base for ACTH. The ACTH release and permeation process depends on both viscosity and ACTH concentration. The higher the hormone concentration, the higher the amount of released ACTH but it reduces the amount of ACTH penetrating through porcine skin.

Abstract
The aim of this retrospective study of children affected by epileptic encephalopathy was to evaluate seizure frequency, electroencephalographic pattern and neuropsychological status, before and after intravenous methylprednisolone therapy. Eleven children with epileptic encephalopathy were administered one cycle of intravenous methylprednisolone (15-30 mg/kg/day for three consecutive days, once a month for four months) in addition to constant dosages of their regular antiepileptic drugs. The treatment resulted in statistically significant reductions of generalized slow spike-and-wave discharges (p<0.0028) and seizure frequency (p<0.013), which persisted even after methylprednisolone pulse therapy was stopped. A globally positive outcome was noted in 9/11 patients (81.8%). This methylprednisolone treatment regimen did not cause significant or persistent adverse effects. We suggest that children with epileptic encephalopathy without an underlying structural lesion could be the best candidates for intravenous methylprednisolone pulse therapy.

Knockdown of Carboxypeptidase A6 in Zebrafish Larvae Reduces Response to Seizure-Inducing Drugs and Causes Changes in the Level of mRNAs Encoding Signaling Molecules. PLoS One 2016; 11:e0152905.

Abstract
Carboxypeptidase A6 (CPA6) is an extracellular matrix metallocarboxypeptidase that modulates peptide and protein function by removal of hydrophobic C-terminal amino acids. Mutations in the human CPA6 gene that reduce enzymatic activity in the extracellular matrix are associated with febrile seizures, temporal lobe epilepsy, and juvenile myoclonic epilepsy. The characterization of these human mutations suggests a dominant mode of inheritance by haploinsufficiency through loss of function mutations, however the total number of humans with pathologic mutations in CPA6 identified to date remains small. To better understand the relationship between CPA6 and seizures we investigated the effects of morpholino knockdown of cpa6 mRNA in zebrafish (Danio rerio) larvae. Knockdown of cpa6 mRNA resulted in resistance to the effect of seizure-inducing drugs pentylenetetrazole and pilocarpine on swimming behaviors. Knockdown of cpa6 mRNA also reduced the levels of mRNAs encoding neuropeptide precursors (bdnf, npy, chga, pcsk1nl, tac1, nts, edn1), a neuropeptide processing enzyme (cpe), transcription factor (c-fos), and molecules implicated in glutamatergic signaling (grin1a and slc1a2b). Treatment of zebrafish embryos with 60 mM pilocarpine for 1 hour led to reductions in levels of many of the same mRNAs when measured 1 day after pilocarpine exposure, except for c-fos which was elevated 1 day after pilocarpine treatment. Pilocarpine treatment, like cpa6 knockdown, led to a reduced sensitivity to pentylenetetrazole when tested 1 day after pilocarpine treatment. Taken together, these results add to mounting evidence that peptidergic systems participate in the biological effects of seizure-inducing drugs, and are the first in vivo demonstration of the molecular and behavioral consequences of cpa6 insufficiency.

Abstract
BACKGROUND Many different corticosteroid treatment schedules have been used in order to treat refractory epileptic seizures with encouraging effects on seizure reduction in many epileptic syndromes. OBJECTIVE The objective is to report our experience with a hybrid treatment regimen for refractory seizures in children with epilepsies other than West and Landau-Kleffner syndrome. We hypothesized that a pulse of corticosteroids effectively reduces seizures while low-dosage maintenance treatment reduces side effects. The results are compared with results from a review of reported corticosteroid and ACTH treatments. METHODS In this retrospective observational study, 26 children diagnosed with epilepsy with refractory seizures other than West syndrome and Landau-Kleffner syndrome were eligible for a treatment regimen consisting of three days intravenous methylprednisolone (20 mg per kilogram per day) followed by twelve weeks oral prednisolone (0.5 mg per kilogram on alternate days), concluded with a taper phase. Data on effectiveness and side effects were obtained. End-points were the percentages of patients who became seizure free or responded well. RESULTS Twenty-one patients received the study treatment. Nine (43%) responded well and 6 (29%) became seizure free. All but one patient had a relapse of seizures. Four patients had reversible adverse effects. Data extracted from the literature were consistent with a good response in 48% of 192 children treated with different corticosteroids and in 69% of 103 patients treated with ACTH. CONCLUSION This new hybrid therapy of a pulse of intravenous methylprednisolone and alternate day oral prednisolone is effective with a favourable side effect profile. Results on efficacy and safety justify a randomized controlled trial.

Abstract
INTRODUCTION In the chronic phase of Hemiconvulsion-Hemiplegia-Epilepsy (HHE) syndrome, developing epilepsy may be intractable. Herein, we report a case where adrenocorticotropic hormone (ACTH) ceased an intractable habitual partial seizure in a patient with HHE syndrome. CASE REPORT A developmentally normal one-year-old girl presented with left focal motor status epilepticus in the clinical course of rotavirus infection. She was diagnosed with HH syndrome. At 4 months after status epilepticus, she developed partial seizures that occurred daily, and which resulted in a stooped posture, head rotation to the right, and contraction of both upper limbs predominantly in the left arm. At this time, she was diagnosed with idiopathic HHE syndrome. Her seizures were not reduced by sodium valproate, clonazepam, clobazam, zonisamide, phenytoin, phenobarbital, topiramate, lamotrigine, or liposteroid. At the age of 7, ACTH therapy was performed. On the 10th day of ACTH therapy, the habitual seizure was ceased. However, partial seizures characterized by left arm contraction then developed. Treatment with 350 mg/day lamotrigine prevented this emerging seizure. She has been free of both seizure types for more than one year, with no serious adverse effects of ACTH therapy. CONCLUSION We suggest that ACTH therapy may be useful for patients with HHE, although further studies are required.

Efficacy of long term weekly ACTH therapy for intractable epilepsy. Brain Dev 2015; 37:449-54.

Abstract
BACKGROUND Adrenocorticotropic hormone (ACTH) therapy is the first-line therapy for infantile spasms, and is effective for many other intractable epilepsies. While spasms may respond to ACTH for weeks, a substantial proportion of patients develop recurrent seizures over a yearly period. To maintain efficacy, we treated two children with intractable epilepsy with weekly ACTH therapy for 1 year and described the changes in clinical seizures, electroencephalograms, developmental assessments and side effects. SUBJECTS AND METHODS A girl with infantile spasms due to lissencephaly and a boy with atypical absence seizures were studied. In both cases, seizures were frequent and resistant to antiepileptic drugs; electroencephalograms showed continuous epileptiform activities, and the patients' development was delayed and stagnant prior to ACTH treatment. The initial ACTH therapy (daily 0.015 mg/kg for 2 weeks, 0.015 mg/kg every 2 days for 1 week, 0.0075 mg/kg every 2 days for 1 week), was transiently effective in both cases. The second-round ACTH therapy consisted of the initial ACTH therapy protocol followed by weekly ACTH injections (0.015 mg/kg or 0.0075 mg/kg) for 1 year. Both cases were followed for at least 1 year after therapy. RESULTS In both patients, clinical seizures were completely controlled during and 1 year after the second-round AHCH therapy. Continuous epileptiform discharges disappeared, while intermittent interictal epileptiform discharges remained. Both patients showed some developmental gains after achieving seizure control. No serious side effects were recorded. CONCLUSION Further studies are warranted to determine if a long-term weekly ACTH is a safe and effective treatment for intractable epilepsy.

Abstract
The role of immunity and inflammation appears to be an integral part of the pathogenic processes associated with some seizures, particularly with refractory epilepsy. Prompt treatment with immunotherapy may lead to better outcomes. Immune treatment options for treatment of epilepsy include therapies such as corticosteroids, immunoglobulins, plasmapheresis, or steroid-sparing drugs such as azathioprine. Recent alternatives have included even more aggressive treatment with cyclophosphamide, anti-pre-B-lymphocyte monoclonal antibody rituximab, and monoclonal antibodies such as efalizumab or natalizumab, which are presently used for other inflammatory disorders. Randomized controlled trials of immunotherapy in presumed autoimmune epilepsy are needed to provide further support for the rapid use of immunotherapy in patients with immune mediated epilepsy.

Abstract
We describe our experience with intravenous methylprednisolone pulse therapy in older children with refractory epilepsy. Patients with refractory epilepsy, who were treated with steroids between 2005 and 2010, were retrospectively selected from the database of the pediatric epilepsy clinic at Assaf Harofeh Medical Center. Eight patients (5 boys) aged 1.1 to 9 years (5.2 ± 2.6) were identified. Intravenous methylprednisolone 30 mg/kg/d was given to all patients for 5 days in addition to a stable dosage of the regular antiepileptic drugs. Transient side effects were reported in 4 of the patients during pulse therapy. Significant clinical improvement was noted in 4 patients, accompanied by a significant reduction of the amplitude of the spike-slow wave discharges on the electroencephalogram (EEG). Children with refractory epilepsy, abnormal EEG background, and high-amplitude spike-slow wave discharges appear to be the best candidates for intravenous methylprednisolone pulse therapy.

Abstract
Refractory convulsive status epilepticus occurs when seizures are not controlled with initial benzodiazepine therapy or a subsequent anticonvulsant drug. Typically drug-induced anesthesia is then pursued with midazolam or a barbiturate. This results in prolonged, intensive care, which requires meticulous attention to medical management to minimize complications. When seizures persist other options must be considered. These include (1) other medications, (2) surgery, (3) the ketogenic diet, (4) hypothermia, (5) inhalational anesthetic agents, and (6) immune modulating therapy. This review addresses the literature related to the use of the latter (4) treatment options. I will discuss the role of each treatment and review the evidence for it's use, along with possible side-effects.

Abstract
Adrenocorticotropic hormone (ACTH) has a long track record for the treatment of infantile spasms. However, there is paucity of data on the use of ACTH in the treatment of epilepsy beyond infantile spasms. We report the use of ACTH in two children with refractory generalized epilepsy. Both patients responded well. ACTH may be considered as a useful adjunctive therapy in patients with intractable generalized seizures. Side effects and cost however, remain important concerns.

Abstract
Steroids are commonly used for the treatment of intractable epilepsy. Deflazacort has shown similar effects to prednisone, but with a less worrying adverse-effect profile. In this study, we first compared the efficacy, safety, and seizure relapse rate of deflazacort versus hydrocortisone in children affected by drug-resistant epilepsies. This was an open, non-blinded, randomized clinical study of 35 children affected by drug-resistant epilepsies. The study lasted 12 months. Group 1 (16 patients) received hydrocortisone for 6 months; group 2 (19 patients) was treated with deflazacort for the entire study period. Drug efficacy and tolerability were evaluated after 6 months of therapy. Seizure relapse rates were evaluated 12 months after the start of the study. After 6 months of therapy, hydrocortisone was effective in 44% of patients (responders, with a decrease in seizure frequency of >50%). Deflazacort was effective in 47% of patients (P=0.9). Adverse events occurred in 37% of patients using hydrocortisone and in none of those using deflazacort (P=0.002). At the end of the study, seizure relapse rate resulted significantly higher in group 1 than in group 2 (P=0.04). Hydrocortisone may be useful in the treatment of severely drug-resistant childhood epilepsies. However, its effects may be transient. Deflazacort should be considered in the therapeutic armamentarium for epileptic encephalopathies. The drug is as effective as hydrocortisone and may be used in therapy for a long period, with a less worrying adverse-effect profile.

Abstract
Refractory status epilepticus describes continuing seizures despite adequate initial pharmacologic treatment. This situation is common in children, but few data are available to guide management. We review the literature related to the pharmacologic treatment and overall management of refractory status epilepticus, including midazolam, pentobarbital, phenobarbital, propofol, inhaled anesthetics, ketamine, valproic acid, topiramate, levetiracetam, pyridoxine, corticosteroids, the ketogenic diet, and electroconvulsive therapy. Based on the available data, we present a sample treatment algorithm that emphasizes the need for rapid therapeutic intervention, employs consecutive medications with different mechanisms of action, and attempts to minimize the risk of hypotension. The initial steps suggest using benzodiazepines and phenytoin. Second steps suggest using levetiracetam or valproic acid, which exert few hemodynamic adverse effects and have multiple mechanisms of action. Additional management strategies that could be employed in tertiary-care settings, such as coma induction guided by continuous electroencephalogram monitoring and surgical options, are also discussed.
