Heliyon 2024; 10:e34869. [PMID: 39144941 PMCID: PMC11320484 DOI: 10.1016/j.heliyon.2024.e34869] [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: 03/16/2024] [Revised: 06/25/2024] [Accepted: 07/17/2024] [Indexed: 08/16/2024] Open
Abstract
Background Gynecological issues and sexually transmitted infections (STIs) pose significant challenges to women's health, particularly in developing nations. These challenges are exacerbated by limited access to modern reproductive healthcare facilities, economic constraints, and entrenched cultural norms. Consequently, most of the Pakistani population relies on traditional ethno-medicinal healthcare systems. This preference stems from the ease of access, affordability, widespread availability, and inherent trust placed in these alternative healthcare methods. Aim/objective The inquiry aimed to report details on the application of conventional uses of plants in the health field in rural areas that could contribute to advancing the natural discovery of drugs. The objective of this analysis is to provide researchers with information on conventional and empirical knowledge of plant species concerning women's diseases. Methodology Information on the common use of medicinal plants in treating women's diseases was gathered from electronic databases. As a keyword for the quest, ethnobotany, and ethnopharmacology were used together with gynecological complications. Result The work of the current analysis has revealed that 217 plant species belonging to 89 families have been used in Pakistan's rural communities. The majority of plant species belong to the Apiaceae family, followed by the Asteraceae, Fabaceae, Solanaceae, Rosaceae, Lamiaceae, and other families. The biological interpretation of plants used in rural communities of Pakistan revealed that herbs and trees are the dominant forms with 58 % and 23 % respectively while shrubs and sub-shrubs with a low percentage of 17 % and 2 %. In natural preparation, leaves 29 %, flowers 22 %, seeds 14 %, fruits 14 %, roots 13 %, bark 7 %, and stems 5 % were the most used parts respectively and aerial parts, dried pericarp, bulb, bud, berry, latex, wood, rhizome, husk, fruit coat, oil, resins, twigs, and shoot were also used in minimum percentage. A multitude of plant species have found extensive application in the management of diverse women's health issues. These encompass concerns such as fatigue, mood fluctuations attributed to menstrual problems, gonorrhea, complications related to pregnancy, cravings for specific foods, throbbing breast pain, abdominal and pelvic cramps, excessive vaginal discharge, mastitis, irritability, abortion-related matters, headaches, uterine hemorrhage, Menorrhagia, Amenorrhea, Menopause, Vomiting Abortion, infertility and lactation challenges, as well as the regulation of lochia flow. Conclusion This review provides remarkable information about the use of medicinal plants against women's diseases in the rural communities of Pakistan. It opens the gateway for the discovery of natural drug development.

Eur J Pharmacol 2024; 976:176667. [PMID: 38795754 DOI: 10.1016/j.ejphar.2024.176667] [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: 01/27/2024] [Revised: 04/24/2024] [Accepted: 05/22/2024] [Indexed: 05/28/2024]
Abstract
Migraine, a debilitating neurological condition, significantly affects patients' quality of life. Fenofibrate, a peroxisome proliferator-activated receptor alpha (PPAR-α) agonist approved for managing dyslipidemia, has shown promise in treating neurological disorders. Therefore, this study aims to investigate the protective effects of fenofibrate against nitroglycerin (NTG)-induced chronic migraine in rats. Migraine was induced in rats by administering five intermittent doses of NTG (10 mg/kg, i. p.) on days 1, 3, 5, 7, and 9. Rats were treated with either topiramate (80 mg/kg/day, p. o.), a standard drug, or fenofibrate (100 mg/kg/day, p. o.) from day 1-10. Fenofibrate significantly improved mechanical and thermal hypersensitivity, photophobia, and head grooming compared to topiramate. These effects were associated with reduced serum levels of nitric oxide (NO), calcitonin gene-related peptide (CGRP), and pituitary adenylate cyclase-activating polypeptide (PACAP). Furthermore, fenofibrate down-regulated c-Fos expression in the medulla and medullary pro-inflammatory cytokine contents. Additionally, fenofibrate attenuated NTG-induced histopathological changes in the trigeminal ganglia and trigeminal nucleus caudalis. These effects were associated with the inhibition of CGRP/p-CREB/purinergic 2X receptor 3 (P2X3) and nerve growth factor (NGF)/protein kinase C (PKC)/acid-sensing ion channel 3 (ASIC3) signaling pathways. This study demonstrates that fenofibrate attenuated NTG-induced migraine-like signs in rats. These effects were partially mediated through the inhibition of CGRP/p-CREB/P2X3 and NGF/PKC/ASIC3 signaling pathways. The present study supports the idea that fenofibrate could be an effective candidate for treating migraine headache without significant adverse effects. Future studies should explore its clinical applicability.

[PMID: 39013292 DOI: 10.1016/j.yebeh.2024.109897] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/08/2024] [Revised: 05/05/2024] [Accepted: 06/09/2024] [Indexed: 07/18/2024]
Abstract
OBJECTIVE To compare the effects of levetiracetam(LEV), lamotrigine(LTG), oxcarbazepine(OXC), topiramate(TPM) and valproate (VPA) on postictal state (PIS). METHODS A total of 187 epilepsy patients undergoing monotherapy were enrolled in a long-term follow-up study at the Affiliated Hospital of Yangzhou College. This included 30 patients on levetiracetam, 41 on valproate, 30 on oxcarbazepine, 28 on topiramate, and 31 on lamotrigine. A control group of 28 newly diagnosed or previously untreated epilepsy patients was also included. The Liverpool Seizure Severity Scale 2.0 (LSSS2.0) and the Seizure Severity Questionnaire (SSQ) were utilized to evaluate the patients' condition, with comparison based on the results of the postictal status items. EEG during PIS termination was assessed using the Grand Total EEG score (GTE) as an objective tool to measure the impact of Antiseizure medications (ASMs) on the post-seizure state. RESULTS The LSSS2.0 score indicated a statistically significant difference in post-seizure status score among the 5 groups (p < 0.05). The difference between the 5 groups and the control group was statistically significant (p < 0.05). Results of the SSQ demonstrated that all 5 drugs significantly reduced the post-seizure status score compared to the control group (p < 0.05). The GTE score revealed that, in the later stage of the seizure, the GTE score of the levetiracetam group, valproate group, oxcarbazepine group, and lamotrigine group significantly decreased compared to the control group (P < 0.05). There was no significant decrease in the GTE score in the topiramate group (P < 0.05). CONCLUSION Levetiracetam, lamotrigine, oxcarbazepine, topiramate, and valproate demonstrate favorable efficacy in ameliorating the severity of post-seizure condition. Further investigations are warranted to assess the potential of other widely employed anti-seizure medications in enhancing post-seizure status.

Topiramate treatment during adolescence induces short and long-term alterations in the reproductive system of female rats. Reprod Toxicol 2024; 126:108601. [PMID: 38705260 DOI: 10.1016/j.reprotox.2024.108601] [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: 11/16/2023] [Revised: 04/16/2024] [Accepted: 04/29/2024] [Indexed: 05/07/2024]
Abstract
Topiramate (TPM) is an antiepileptic drug used for treating epilepsy in children, and migraine in teenagers. In this context, preclinical studies with adult female rats observed reproductive system abnormalities following treatment with TPM. Additionally, exposure to endocrine disruptors during developmental plasticity periods, such as childhood and adolescence, may influence characteristics in the adult individual. This study evaluated whether treatment with TPM during developmental periods influences the reproductive system of female rats either immediately or in adult life. Female Wistar rats were treated with TPM (41 mg/Kg/day) by oral gavage from postnatal day (PND) 16-28, or PND 28-50, which correspond to childhood and adolescence, respectively, and euthanized either 24 h after the final administration or during adulthood. Treatment with TPM during adolescence induced short-term increase in uterus and ovary weights and reduction in endometrial stroma thickness. Adult animals treated during adolescence displayed reduced primordial ovarian follicles' numbers, and increased primary and pre-antral ovarian follicles' numbers. Treatment during childhood induced no short or long-term differences. These results indicate TPM treatment during adolescence is capable of inducing short and long-term alterations on the reproductive system of female Wistar rats.

Abstract
BACKGROUND Acupuncture has been used for the treatment of chronic migraine, but high-quality evidence is scarce. We aimed to evaluate acupuncture's efficacy and safety compared to topiramate for chronic migraine. METHODS This double-dummy randomized controlled trial included participants aged 18-65 years diagnosed with chronic migraine. They were randomly assigned (1:1) to receive acupuncture (three sessions/week) plus topiramate placebo (acupuncture group) or topiramate (50-100 mg/day) plus sham acupuncture (topiramate group) over 12 weeks, with the primary outcome being the mean change in monthly migraine days during weeks 1-12. RESULTS Of 123 screened patients, 60 (mean age 45.8, 81.7% female) were randomly assigned to acupuncture or topiramate groups. Acupuncture demonstrated significantly greater reductions in monthly migraine days than topiramate (weeks 1-12: -2.79 [95% CI: -4.65 to -0.94, p = 0.004]; weeks 13-24: -3.25 [95% CI: -5.57 to -0.92, p = 0.007]). No severe adverse events were reported. CONCLUSIONS Acupuncture may be safe and effective for treating chronic migraine. The efficacy of 12 weeks of acupuncture was sustained for 24 weeks and superior to that of topiramate. Acupuncture can be used as an optional preventive therapy for chronic migraine.

Abstract
The American Society of Addiction Medicine/American Academy of Addiction Psychiatry (ASAM/AAAP) Clinical Practice Guideline on the Management of Stimulant Use Disorder provides guidance on evidence-based strategies for the treatment of stimulant use disorders (StUDs), stimulant intoxication, and stimulant withdrawal, as well as secondary and tertiary prevention of harms associated with stimulant use. The Clinical Guideline Committee (CGC) comprised experts from ASAM and AAAP representing a range of clinical settings and patient populations. The guideline was developed following modified GRADE methodology. The process included a systematic literature review as well as several targeted supplemental searches. The CGC utilized Evidence to Decision tables to review available evidence and rate the strength of each recommendation. The clinical practice guideline was revised based on external stakeholder review. Key takeaways included: Contingency management represents the current standard of care for treatment of StUDs; Pharmacotherapies may be utilized off-label to treat StUDs; Acute stimulant intoxication can result in life-threatening complications that should be addressed in an appropriate level of care; Secondary and tertiary prevention strategies should be used to reduce harms related to risky stimulant use.

Abstract
INTRODUCTION Approximately 50% of patients that receive a CGRP(r) MoAb for the preventative treatment of migraine are expected to discontinue therapy. For patients that discontinue CGRP(r) MoAb therapy, few clinical options are available. One potential option is to switch CGRP(r) MoAbs, however, data concerning the efficacy of this intervention is scarce. AREAS COVERED This manuscript aims to summarize all available data concerning the potential efficacy of switching CGRP(r) MoAbs following previous medication discontinuation. Data was sourced by completing a database search for the terms: 'CGRP monoclonal antibody switch OR CGRP monoclonal antibody switching.' EXPERT OPINION While data considering the potential efficacy of CGRP(r) switching continues to grow, our expert opinion supports the most recent European Headache Federation statement regarding CGRP(r) MoAb prescribing practices, concluding that there remains insufficient data to determine the efficacy of this intervention. As this topic is of significant clinical importance, we recommend a call-to-action to expand on current data considering the therapeutic options for patients that discontinue CGRP(r) MoAb therapy.

Abstract
AIM The present study evaluated whether topiramate (TPM) treatment during the peripubertal period affects vascular parameters of male rats and whether oxidative stress plays a role in these changes. MAIN METHODS Rats were treated with TPM (41 mg/kg/day, gavage) or vehicle (CTR group) from the postnatal day (PND) 28 to 50. At PND 51 and 120 the rats were evaluated for: thoracic aorta reactivity to phenylephrine, in the presence (Endo+) or absence of endothelium (Endo-), to acetylcholine and to sodium nitroprusside (SNP), aortic thickness and endothelial nitric oxide synthase (eNOS) expression. In serum were analyzed: the antioxidant capacity by ferric reducing antioxidant power assay; endogenous antioxidant reduced glutathione, and superoxide anion. Results were expressed as mean ± s.e.m., differences when p < 0.05. STATISTICS Two-way ANOVA (and Tukey's) or Student t-test. KEY FINDINGS At PND 51, the contraction induced by phenylephrine in Endo+ ring was higher in TPM when compared to CTR. At PND 120, the aortic sensitivity to acetylcholine in TPM rats was reduced in comparison with CTR. The aortic eNOs expression and the aortic thickness were similar between the groups. At PND 51 and 120, TPM group presented a decrease in antioxidants when compared to CTR groups and at PND 120, in TPM group the superoxide anion was increased. SIGNIFICANCE Taken together, the treatment of rats with TPM during peripubertal period promoted permanent impairment of endothelial function probably mediated by oxidative stress.

Abstract
OBJECTIVE Topiramate is a repurposed first-line treatment for migraine prophylaxis. The aim of this systematic review and meta-analysis is to critically re-appraise the existing evidence supporting the efficacy and tolerability of topiramate. METHODS A systematic search in MEDLINE, EMBASE, Cochrane CENTRAL, and ClinicalTrials.gov was performed for trials of pharmacological treatment in migraine prophylaxis as of August 13, 2022, following the Preferred Reporting Items for Systematic Reviews (PRISMA). Randomized controlled trials in adult patients that used topiramate for the prophylactic treatment of migraine, with placebo as active comparator, were included. Two reviewers independently screened the retrieved studies and extracted all data. Outcomes of interest were the 50% responder rates, the reduction in monthly migraine days, and adverse events leading to treatment discontinuation. Results were pooled and meta-analyzed, with sensitivity analysis based on the risk of bias of the studies, the monthly migraine days at baseline, and the previous use of other prophylactic treatments. Certainty evidence was judged according to the GRADE framework. RESULTS Eight out of 10,826 studies fulfilled the inclusion/exclusion criteria, accounting for 2,610 randomized patients. Six studies included patients with episodic migraine and two with chronic migraine. Topiramate dose ranged from 50 to 200 mg/day, and all studies included a placebo arm. There was a high certainty that topiramate: 1) increased the proportion of patients who achieved a 50% responder rate in monthly migraine days, compared to placebo [relative risk: 1.61 (95% confidence interval (CI): 1.29-2.01); absolute risk difference: 168 more per 1,000 (95% CI: 80 to 278 more)]; 2) was associated with 0.99 (95% CI: 1.41-0.58) fewer migraine days than placebo; 3) and had a higher proportion of patients with adverse events leading to treatment discontinuation [absolute risk difference 80 patients more per 1,000 (95% CI: 20 to 140 more patients)]. CONCLUSIONS There is high-quality evidence of the efficacy of topiramate in the prophylaxis of migraine, albeit its use poses a risk of adverse events that may lead to treatment discontinuation, with a negative effect on patient satisfaction and adherence to care.

Life (Basel) 2023; 13:1845. [PMID: 37763249 PMCID: PMC10532729 DOI: 10.3390/life13091845] [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: 05/01/2023] [Revised: 07/31/2023] [Accepted: 08/29/2023] [Indexed: 09/29/2023] Open
Abstract
Obesity has emerged as a widespread disease with epidemic proportions, necessitating effective management to enhance the overall health outcomes of patients. Medical intervention for weight loss becomes necessary when diet and exercise prove ineffective, and topiramate emerges as a potential treatment option for this global problem. Currently approved as an anti-epileptic and migraine prophylaxis medication, topiramate is frequently utilized as adjunctive therapy for patients with mood and eating disorders, as well as for alcohol use disorders. Its multifaceted mechanisms of action contribute to reducing neuronal excitation and enhancing neuronal inhibition. Given its variety of mechanisms, topiramate shows several off-label outcomes, including weight loss, for patients prescribed this medication. Although the specific mechanism of action concerning weight loss remains uncertain, various hypotheses have been reported. Notably, topiramate may contribute to weight loss by reducing calorie intake, decreasing fat gain, and lowering triglyceride and cholesterol levels. Additionally, its impact on reward pathways associated with food could play a role. Multiple clinical studies have supported the use of topiramate as a weight-loss medication. Notably, the medication demonstrates effectiveness in reducing body weight across different dosages and sustaining weight loss over time, outperforming alternative weight loss methods. Moreover, it was generally well-tolerated in clinical studies, with few side effects observed. In conclusion, topiramate offers promising potential as a weight loss solution and can be a valuable addition to the range of treatment options for combating obesity.

Long-term efficacy and safety of erenumab in patients with chronic migraine and acute medication overuse: A subgroup analysis. Headache 2023; 63:730-742. [PMID: 37313616 DOI: 10.1111/head.14536] [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: 11/17/2022] [Revised: 05/02/2023] [Accepted: 05/03/2023] [Indexed: 06/15/2023]
Abstract
OBJECTIVE Assess the long-term efficacy and safety of erenumab in patients with chronic migraine with acute medication overuse. BACKGROUND Overuse of acute medication in patients with chronic migraine has been linked to greater pain intensity and disability and may diminish the effectiveness of preventive therapies. METHODS This 52-week open-label extension study followed a 12-week double-blind placebo-controlled study in which patients with chronic migraine were randomized 3:2:2 to placebo or once-monthly erenumab 70 mg or 140 mg. Patients were stratified by region and medication overuse status. Patients received erenumab 70 mg or 140 mg throughout or switched from erenumab 70 to 140 mg (based on protocol amendment to augment safety data at higher dose). Efficacy was assessed in patients with and without medication overuse at parent study baseline. RESULTS Of 609 patients enrolled in the extension study, 252/609 (41.4%) met the criteria for medication overuse at parent study baseline. At Week 52, the mean change in monthly migraine days from parent study baseline was -9.3 (95% confidence interval: -10.4, -8.1 days) in the medication overuse subgroup versus -9.3 (-10.1, -8.5 days) in the non-medication overuse subgroup (combined erenumab doses); proportion of patients achieving ≥50% reduction in monthly migraine days at Week 52 was 55.9% (90/161; 48.2%, 63.3%) versus 61.3% (136/222; 54.7%, 67.4%), respectively. Among baseline users of acute migraine-specific medication, the mean change in monthly migraine-specific medication days at Week 52 was -7.4 (-8.3, -6.4 days) in the medication overuse subgroup versus -5.4 (-6.1, -4.7 days) in the non-medication overuse subgroup. Most patients (197/298; 66.1%) in the medication overuse subgroup transitioned to non-overuse status by Week 52. Erenumab 140 mg was associated with numerically greater efficacy than erenumab 70 mg across all endpoints. No new safety signals were identified. CONCLUSION Long-term erenumab treatment demonstrated sustained efficacy and safety in patients with chronic migraine with and without acute medication overuse.

Abstract
Current treatment options for feline epilepsy are limited to medications that require administration of multiple doses per day or administration of a capsule or large tablet. Expanding the current treatment options could improve patient and owner compliance and optimize seizure control. Topiramate has been used sparingly in veterinary medicine, and limited pharmacokinetic studies have focused on immediate release formulations in dogs. If effective and safe, topiramate extended-release (XR) could broaden the current treatment options for feline epilepsy. The aims of this two-phase study were to establish single-dose pharmacokinetics for topiramate XR in cats, identify a dosing regimen that maintains steady-state plasma drug concentrations within a reference range extrapolated from human medicine (5-20 μg/mL), and evaluate the safety of topiramate XR in cats following multidose administration. Topiramate XR administered orally at 10 mg/kg once daily for 30 days was sufficient to achieve the desired concentrations in all cats. While no clinically apparent adverse effects were observed, four out of eight cats developed subclinical anemia, calling into question the safety of topiramate XR with chronic administration. Further studies are necessary to better understand the potential adverse effects and overall efficacy of topiramate XR for the treatment of feline epilepsy.

Abstract
INTRODUCTION Migraine prophylactic therapy has changed over recent years with the development and approval of monoclonal antibodies (mAbs) targeting the calcitonin gene-related peptide (CGRP) pathway. As new therapies emerged, leading headache societies have been providing guidelines on the initiation and escalation of such therapies. However, there is a lack of robust evidence looking at the duration of successful prophylaxis and the effects of therapy discontinuation. In this narrative review we explore both the biological and clinical rationale for prophylactic therapy discontinuation to provide a basis for clinical decision-making. METHODS Three different literature search strategies were conducted for this narrative review. These include i) stopping rules in comorbidities of migraine in which overlapping preventives are prescribed, notably depression and epilepsy; ii) stopping rules of oral treatment and botox; iii) stopping rules of antibodies targeting the CGRP (receptor). Keywords were utilized in the following databases: Embase, Medline ALL, Web of Science Core collection, Cochran Central Register of Controlled Trials, and Google Scholar. DISCUSSION Reasons to guide decision-making in stopping prophylactic migraine therapies include adverse events, efficacy failure, drug holiday following long-term administration, and patient-specific reasons. Certain guidelines contain both positive and negative stopping rules. Following withdrawal of migraine prophylaxis, migraine burden may return to pre-treatment level, remain unchanged, or lie somewhere in-between. The current suggestion to discontinue CGRP(-receptor) targeted mAbs after 6 to 12 months is based on expert opinion, as opposed to robust scientific evidence. Current guidelines advise the clinician to assess the success of CGRP(-receptor) targeted mAbs after three months. Based on excellent tolerability data and the absence of scientific data, we propose if no other reasons apply, to stop the use of mAbs when the number of migraine days decreases to four or fewer migraine days per month. There is a higher likelihood of developing side effects with oral migraine preventatives, and so we suggest stopping these drugs according to the national guidelines if they are well tolerated. CONCLUSION Translational and basic studies are warranted to investigate the long-term effects of a preventive drug after its discontinuation, starting from what is known about the biology of migraine. In addition, observational studies and, eventually, clinical trials focusing on the effect of discontinuation of migraine prophylactic therapies, are essential to substantiate evidence-based recommendations on stopping rules for both oral preventives and CGRP(-receptor) targeted therapies in migraine.

Abstract
OBJECTIVES To investigate the impact of topiramate versus flunarizine on the non-headache symptoms (NHS) of migraine, and to observe the changes of dopamine (DA) and prolactin (PRL) before and after prophylactic treatment. METHODS Sixty-six episodic migraine patients were enrolled and randomized 1:1 to receive either flunarizine or topiramate treatment. Clinical characteristics and NHS associated with migraine were investigated before and after prophylactic treatment. The DA and PRL levels were also determined before and after prophylactic treatment. RESULTS The NHS of migraine in the two groups were significantly better after treatment than before treatment in premonitory phase (PP), headache phase (HP), and resolution phase (RP). The NHS in the two groups had no significant difference in PP, HP, and RP before and after treatment. In the flunarizine group, the PRL content after treatment was significantly higher than that before treatment (t = -4.097, p < 0.001), but the DA content was decreased slightly compared with that before treatment (t = 1.909, p = 0.066). There was no significant difference in PRL content (t = 1.099, p = 0.280) and DA content (t = 1.556, p = 0.130) in topiramate group before and after treatment. CONCLUSIONS The two classical prophylactic drugs of migraine were significantly effective in treating the NHS of migraine, but there was no significant difference between the two drugs. The DA-PRL axis may be involved in the underlying mechanism of the flunarizine treatment for the NHS of migraine.

Abstract
Migraine and epilepsy are fundamentally distinct disorders that can frequently coexist in the same patient. These two conditions significantly differ in diagnosis and therapy but share some widely- used preventive treatments. Antiseizure medications (ASMs) are the mainstay of therapy for epilepsy, and about thirty different ASMs are available to date. ASMs are widely prescribed for other neurological and non-neurological conditions, including migraine. However, only topiramate and valproic acid/valproate currently have an indication for migraine prophylaxis supported by high-quality evidence. Although without specifically approved indications and with a low level of evidence or recommendation, several other ASMs are used for migraine prophylaxis. Understanding ASM antimigraine mechanisms, including their ability to affect the pro-migraine calcitonin gene-related peptide (CGRP) signaling pathway and other pathways, may be instrumental in identifying the specific targets of their antimigraine efficacy and may increase awareness of the neurobiological differences between epilepsy and migraine. Several new ASMs are under clinical testing or have been approved for epilepsy in recent years, providing novel potential drugs for migraine prevention to enrich the treatment armamentarium and drugs that inhibit the CGRP pathway.

Abstract
ABSTACT BACKGROUND: DRAGON was a phase 3, randomised, double-blind, placebo-controlled study which evaluated the efficacy and safety of erenumab in patients with chronic migraine (CM) from Asia not adequately represented in the global pivotal CM study. METHODS DRAGON study was conducted across 9 Asian countries or regions including mainland China, India, the Republic of Korea, Malaysia, the Philippines, Singapore, Taiwan, Thailand, and Vietnam. Patients (N = 557) with CM (aged 18-65 years) were randomised (1:1) to receive once-monthly subcutaneous erenumab 70 mg or matching placebo for 12 weeks. The primary endpoint was the change in monthly migraine days (MMD) from baseline to the last 4 weeks of the 12-week double-blind treatment phase (DBTP). Secondary endpoints included achievement of ≥ 50% reduction in MMD, change in monthly acute headache medication days, modified migraine disability assessment (mMIDAS), and safety. Study was powered for the primary endpoint of change from baseline in MMD. RESULTS At baseline, the mean (SD) age was 41.7 (± 10.9) years, and 81.5% (n = 454) patients were women. The mean migraine duration was 18.0 (± 11.6) years, and the mean MMD was 19.2 (± 5.4). 97.8% (n = 545) randomised patients completed the DBTP. Overall, demographics and baseline characteristics were balanced between the erenumab and placebo groups except for a slightly higher proportion of women in the placebo group. At Week 12, the adjusted mean change from baseline in MMD was - 8.2 days for erenumab and - 6.6 days for placebo, with a statistically significant difference for erenumab versus placebo (adjusted mean difference vs placebo: - 1.57 [95%CI: - 2.83, - 0.30]; P = 0.015). A greater proportion of patients treated with erenumab achieved ≥ 50% reduction in MMD versus placebo (47.0% vs 36.7%, P = 0.014). At Week 12, greater reductions in monthly acute headache medication days (- 5.34 vs - 4.66) and mMIDAS scores (- 14.67 vs - 12.93) were observed in patients treated with erenumab versus placebo. Safety and tolerability profile of erenumab was comparable to placebo, except the incidence of constipation (8.6% for erenumab vs 3.2% for placebo). CONCLUSION DRAGON study demonstrated the efficacy and safety of erenumab 70 mg in patients with CM from Asia. No new safety signals were observed during the DBTP compared with the previous trials.

Abstract
Objective To assess the prevalence and burden of autonomic symptoms in migraine, and determine the relationship with migraine frequency. Background Autonomic symptoms in migraine have been theorized to occur in the setting of inter-ictal sympathetic hypoactivity and hyper-sensitivity. There is limited data prospectively assessing cranial and extra-cranial autonomic symptoms with a validated instrument, or longitudinal data on the relationship between migraine disease activity and autonomic symptoms. Methods Patients attending a single tertiary academic center were recruited into a prospective cohort study between September 2020 and June 2022. In addition to standard clinical care, they completed several surveys including the Composite Autonomic Symptom Scale (COMPASS-31) questionnaire, a validated survey of autonomic symptoms. Results A total of 43 patients (66.7% female, median age 42, IQR 17) were included in the final analysis. There was a baseline 20 monthly headache days (MHD) (IQR 21.7), and 65.1% of the population had chronic migraine by ICHD-3 criteria. A significantly elevated weighted COMPASS-31 score was reported in 60.5% of respondents (mean 30.3, SD 13.3) at baseline. After 12 months treatment, significant improvements were reported in migraine frequency (median MHD 20-8.7) and disability (median Migraine Disability Assessment Score 67-48), but not in autonomic symptoms (mean score 30.3, SD 11.2). Conclusion Autonomic symptoms were frequently reported in patients with migraine. However, they did not correlate with headache frequency or reversion to episodic frequency. Further study is required to elucidate specific approaches and treatments for autonomic symptoms, and further evaluate the underlying pathophysiological mechanisms.

Abstract
Migraine, a primary headache disorder is a chronic and complex neurological disease that affects millions of people worldwide, impacting their quality of life. It is one of the most common reasons why individuals seek the advice of their physician, and is one of the most common referrals seen in the offices of general neurologists and headache specialists. In the past decade, there has been robust research on not only the pathophysiology of migraine but in the efforts to treat and, importantly, prevent. The introduction of calcitonin gene related peptide antagonists (CGRP-A) have opened new doors for preventive treatment options. OnabotulinumtoxinA (BoNTA) has remained a staple in the treatment of chronic migraine with data emerging with combination therapy. Neurostimulation has offered additional nonpharmacologic approaches to migraine treatment. In addition to lifestyle and behavioral modifications, these have changed the landscape of migraine prevention.

Abstract
Migraine headache is a widespread and complex neurobiological disorder that is characterized by unilateral headaches that are often accompanied by photophobia and phonophobia. Migraine is one of the leading chief complaints in the emergency department with negative impacts on quality of life and activities of daily living. The high number of emergency presentations also results in a significant economic burden. Its risk factors include family history, genetics, sex, race, socioeconomics, the existence of comorbid conditions, and level of education. Triggers include stress, light, noise, menstruation, weather, changes in sleep pattern, hunger, dehydration, dietary factors, odors, and alcohol. The International Headache Society has defined criteria for the diagnosis of migraine with and without aura. The pathophysiology of migraine headaches is multifactorial so there are a variety of treatment approaches. The current treatment approach includes abortive medications and prophylactic medications. Abortive medications include the first-line treatment of triptans, followed by ergot alkaloids, and calcitonin gene-related peptide (CGRP) receptor antagonists along with supplemental caffeine and antiemetics. Trigeminal afferents from the trigeminal ganglion innervate most cranial tissues and many areas of the head and face. These trigeminal afferents express certain biomarkers such as calcitonin gene-related peptide (CGRP), substance P, neurokinin A, and pituitary adenylate cyclase-activating polypeptide that are important to the pain and sensory aspect of migraines. In this comprehensive review, we discuss Zavegepant, a calcitonin gene-related peptide receptor antagonist, as a new abortive medication for migraine headaches.

Abstract
PURPOSE OF REVIEW The aim of this review is to aid in decision-making when choosing safe and effective options for preventive migraine medications. RECENT FINDINGS In Part 2, we have compiled clinically relevant safety considerations for commonly used migraine prophylactic treatments. Preventive treatment of episodic migraine includes nonspecific and migraine-specific drugs. While medications from several pharmacological classes-such as anticonvulsants, beta-blockers, and antidepressants-have an established efficacy in migraine prevention, they are associated with a number of side effects. The safety of migraine-specific treatments such as anti-CGRP monoclonal antibodies and gepants are also discussed. This review highlights safety concerns of commonly used migraine prophylactic agents and offers suggestions on how to mitigate those risks.

Abstract
Topiramate is an anticonvulsant drug effective against a wide range of seizures and epilepsies. The present study was conducted to investigate the possible protective effect of topiramate on indomethacin-induced gastric mucosal damage in rats. The animals were randomly distributed into four experimental groups with 10 animals in each group. Group 1 was the control group received vehicle only (DMSO at 1:4 (w/v)), group 2 was the model group received indomethacin (50 mg/kg; i.p.), and groups 3 and 4 received topiramate (100 mg/kg; i.p.) and ranitidine (100 mg/kg; i.p.), respectively, 1 h before indomethacin (50 mg/kg; i.p.). The efficacy of topiramate was compared with ranitidine. Animals were euthanized 4 h after indomethacin administration, and gastric tissues were collected for macroscopical, histopathological, and biochemical analyses. The mucosal lesions in the gastric corpus were evaluated by pathological examinations. The results revealed that the administration of indomethacin caused evident gastric mucosal damage with morphological and histological manifestation, whereas topiramate pretreatment extensively ameliorated the gastric injuries. Topiramate pretreatment also reduced the contents of tissue malonaldehyde, enhanced ferric reducing antioxidant power value and glutathione levels, and increased the activity of superoxide dismutase, catalase, and glutathione peroxidase in gastric mucosa compared to the model group. Our results indicate that topiramate might possess a protective role against indomethacin-induced gastric ulcers by inhibition of oxidative stress in gastric tissue.

Abstract
CME: Idiopathic Intracranial Hypertension Abstract. Idiopathic intracranial hypertension is a pressure-induced secondary headache disorder and optic neuropathy. It primarily affects obese women of childbearing age and poses an interdisciplinary challenge both diagnostically and therapeutically. The most common symptom of this disorder are headaches frequently accompanied by photo- and/or phonophobia, whose semiology often resembles that of migraine, followed by transient visual obscurations and pulsatile tinnitus. While protection of visual acuity and visual fields are of first therapeutical priority, adequate headache treatment also plays a key role. In the majority of cases, conservative treatment including weight loss and pharmacological therapy is sufficient. In case of a fulminant disease course or loss of visual function, interventional strategies can be applied additionally. Headache treatment is guided by the predominant semiology.

Abstract
OBJECTIVE To compare the efficacy and tolerability of combination treatment of topiramate and greater occipital nerve block to topiramate monotherapy in adult chronic migraine patients. BACKGROUND Options for the preventive treatment of chronic migraine are limited and costly. Combination treatments do not have an evidence base yet. METHODS This was a parallel group, 3 arms with 1:1:1 allocation ratio randomized controlled study in consecutive adult chronic migraine patients attending Headache Clinic in a tertiary care hospital. Patients received either topiramate monotherapy 100 mg/day (group A), or topiramate plus greater occipital nerve block with 40 mg lidocaine (2%) and 80mg (2 ml) methylprednisolone as the first injection followed by monthly injections of lidocaine for the next 2 months (group B) or topiramate plus greater occipital nerve block with 40 mg lidocaine (2%) injections monthly for 3 months (group C). The primary endpoint was the mean change in monthly migraine days at Month 3. Multiple secondary endpoints were assessed that included among others, achievement of ≥50% reduction in mean monthly headache days compared to baseline at Month 3 and assessment for any adverse events. RESULTS One hundred and twenty-five patients were randomized; 41 to group A, 44 to group B, and 40 to group C. Efficacy assessments were done for 121 patients. Patients receiving combination treatment of topiramate and greater occipital nerve block with steroids and lidocaine and greater occipital nerve block with only lidocaine compared to topiramate monotherapy showed greater reductions in monthly migraine days at Month 3 (-9.6 vs -7.3 days; p = 0.003) and (-10.1 vs -7.3 days; p < 0.001) respectively. Greater proportion of patients in both the combination treatment groups (added greater occipital nerve block with and without steroid) achieved ≥50% reduction in mean monthly headache days [71.4% vs 39%; OR (95% CI) 3.9(1.6-9.8); p = 0.004] and [62.4% vs 39%; OR (95% CI) 2.7(1.1-6.7); p = 0.034] respectively, compared to those receiving topiramate monotherapy. Adverse effects between the groups were comparable although patients receiving combination treatment with added greater occipital nerve block reported transient adverse effects like post-injection dizziness, local site swelling, and pain. No serious adverse event was reported. CONCLUSION Combination treatments of topiramate with monthly injections of greater occipital nerve block were more effective in reducing monthly migraine days in chronic migraine than topiramate monotherapy at Month 3. Combination treatments were well tolerated.

Abstract
INTRODUCTION Combination use of onabotulinumtoxinA and calcitonin gene-related peptide (CGRP) monoclonal antibodies (mAbs) has the potential to be more effective than either therapy alone for migraine prevention. METHODS This retrospective, longitudinal chart review included adults with chronic migraine treated at one clinical site with ≥ 2 consecutive cycles of onabotulinumtoxinA and ≥ 1 month of subsequent combination treatment with CGRP mAbs. Charts at time of mAb prescription (baseline) and up to four visits ~ 3, 6, 9, and 12 months post-baseline were reviewed for safety, tolerability, and outcome measures (monthly headache days [MHDs], headache intensity, and migraine-related disability [MIDAS]). RESULTS Of 300 charts reviewed, 257 patients met eligibility criteria (mean age: 50 years; 82% women). Average headache frequency was 21.5 MHDs before initiation of onabotulinumtoxinA and 12.1 MHDs before adding CGRP mAb therapy. Prescribed mAbs were erenumab (78%), fremanezumab (6%), and galcanezumab (16%). Over the entire study, patients discontinued CGRP mAb more frequently than onabotulinumtoxinA (23 vs. 3%). Adverse events occurred in 28% of patients, most commonly constipation (9%). Compared with onabotulinumtoxinA alone (baseline), MHDs decreased significantly at all visits (mean decrease: 3.5-4.0 MHDs over ~ 6-12 months of combination treatment); 45.1% of patients had clinically meaningful improvement in migraine-related disability (≥ 5-point reduction in MIDAS score) after ~ 6 months. CONCLUSIONS In this real-world study, combination treatment with onabotulinumtoxinA and CGRP mAbs was well tolerated, with no new safety signals identified, and was associated with additional clinically meaningful benefits. More real-world and controlled trials should be considered to further assess safety and potential benefits of combination treatment.

Abstract
BACKGROUND We compared the tolerability and efficacy of erenumab, a monoclonal antibody binding to the calcitonin gene-related peptide receptor, to topiramate for migraine prophylaxis in adults. METHODS HER-MES was a 24-week, randomised, double-blind, double-dummy, controlled trial conducted in 82 sites in Germany. Patients with ≥4 migraine days per month and naïve to study drugs were randomly assigned (1:1) to either subcutaneous erenumab (70 or 140 mg/month) plus topiramate placebo (erenumab group) or oral topiramate at the individual dose with optimal efficacy (50-100 mg/day) plus erenumab placebo (topiramate group).The primary endpoint was medication discontinuation due to an adverse event during the double-blind phase. The proportion of patients that achieved ≥50% reduction from baseline in monthly migraine days during the last 3 months of the double-blind phase was a secondary endpoint. RESULTS Seven hundred and seventy-seven patients were randomised (from 22 February 2019 to 29 July, 2020) and 95.1% completed the study. In the erenumab group, 10.6% discontinued medication due to adverse events compared to 38.9% in the topiramate group (odds ratio, 0.19; 95% confidence interval 0.13-0.27; p < 0.001). Significantly more patients achieved a ≥50% reduction in monthly migraine days from baseline with erenumab (55.4% vs. 31.2%; odds ratio 2.76; 95% confidence interval 2.06-3.71; p < 0.001). No new safety signals occurred. CONCLUSIONS Erenumab demonstrated a favourable tolerability and efficacy profile compared to topiramate.Trial registration: ClinicalTrials.gov NCT03828539, URL: https://clinicaltrials.gov/ct2/show/NCT03828539.

Abstract
OBJECTIVE Previous studies have demonstrated that emotional stress, changes in lifestyle habits and infections can worsen the clinical course of migraine. We hypothesize that changes in habits and medical care during coronavirus disease 2019 (COVID-19) lockdown might have worsened the clinical course of migraine. DESIGN Retrospective survey study collecting online responses from migraine patients followed-up by neurologists at three tertiary hospitals between June and July 2020. METHODS We used a web-based survey that included demographic data, clinical variables related with any headache (frequency) and migraine (subjective worsening, frequency, and intensity), lockdown, and symptoms of post-traumatic stress. RESULTS The response rate of the survey was 239/324 (73.8%). The final analysis included 222 subjects. Among them, 201/222 (90.5%) were women, aged 42.5 ± 12.0 (mean±SD). Subjective improvement of migraine during lockdown was reported in 31/222 participants (14.0%), while worsening in 105/222 (47.3%) and was associated with changes in migraine triggers such as stress related to going outdoors and intake of specific foods or drinks. Intensity of attacks increased in 67/222 patients (30.2%), and it was associated with the subjective worsening, female sex, recent insomnia, and use of acute medication during a headache. An increase in monthly days with any headache was observed in 105/222 patients (47.3%) and was related to symptoms of post-traumatic stress, older age and living with five or more people. CONCLUSIONS Approximately half the migraine patients reported worsening of their usual pain during the lockdown. Worse clinical course in migraine patients was related to changes in triggers and the emotional impact of the lockdown.

Abstract
INTRODUCTION Migraine involves neurovascular, functional, and anatomical alterations. Migraineurs experience an intense unilateral and pulsatile headache frequently accompanied with vomiting, nausea, photophobia, etc. Although there is no ideal preventive medication, frequency in migraine days may be partially decreased by some prophylactics, including antihypertensives, antidepressants, antiepileptics, and CGRPergic inhibitors. However, the mechanisms of action involved in antimigraine prophylaxis remain elusive. AREAS COVERED This review recaps some of the main neurovascular phenomena related to migraine and currently available preventive medications. Moreover, it discusses the major mechanisms of action of the recommended prophylactic medications. EXPERT OPINION In the last three years, migraine prophylaxis has evolved from nonspecific to specific antimigraine treatments. Overall, nonspecific treatments mainly involve neural actions, whereas specific pharmacotherapy (represented by CGRP receptor antagonists and CGRPergic monoclonal antibodies) is predominantly mediated by neurovascular mechanisms that may include, among others: (i) reduction in the cortical spreading depression (CSD)-associated events; (ii) inhibition of pain sensitization; (iii) blockade of neurogenic inflammation; and/or (iv) increase in cranial vascular tone. Accordingly, the novel antimigraine prophylaxis promises to be more effective, devoid of significant adverse effects (unlike nonspecific treatments), and more beneficial for the quality of life of migraineurs.

Lee H, Kim DW. Usefulness of extended-release topiramate in patients with epilepsy: A two-year retention study. J Clin Pharm Ther 2021; 46:1412-1417. [PMID: 34146432 DOI: 10.1111/jcpt.13473] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2021] [Revised: 06/03/2021] [Accepted: 06/09/2021] [Indexed: 11/29/2022]
Abstract
WHAT IS KNOWN AND OBJECTIVE Extended-release topiramate (TPM-XR) was recently approved for the treatment of epilepsy, but there is only limited real-world information on the clinical usefulness of TPM-XR in epilepsy patients. We investigated the usefulness of TPM-XR in clinical practice by analysing the retention of TPM-XR in adult epilepsy patients. METHODS We performed a single-centre retrospective study covering two years. Epilepsy patients taking TPM-XR were included in the study and classified into one of three groups: the monotherapy group, in which patients took only TPM-XR; the adjunctive therapy group, in which patients took TPM-XR concomitant with other AEDs; and the switching AED regimen group, in which patient's AED was switched from immediate-release TPM (TPM-IR) to TPM-XR. We evaluated the retention rates of TPM-XR and analysed the differences in retention rate among the three patient groups. RESULTS AND DISCUSSION We included 164 epilepsy patients who received TPM-XR for the treatment of epilepsy. The overall retention rate of TPM-XR was generally favourable: 79.1% after one year and 77.7% after two years. The switching AED regimen group had a better retention rate than the other two groups (p = 0.04), with a one-year retention rate of 90.6% and a two-year retention rate of 88.1%. WHAT IS NEW AND CONCLUSION The favourable retention rate of TPM-XR shows that TPM-XR can be an effective treatment option for epilepsy patients, as either a monotherapy or as an adjunctive therapy. Additionally, switching AED regimen to TPM-XR from TPM-IR can be considered in selected epilepsy patients with poor adherence to TPM-IR.

Abstract
Migraine is a disabling neurovascular disorder, characterized by moderate to severe unilateral headaches, nausea, photophobia, and/or phonophobia, with a higher prevalence in women than in men, which can drastically affect the quality of life of migraine patients. In addition, this chronic disorder is related with metabolic comorbidities associated with the patient's lifestyle, including obesity and diabetes mellitus (DM). Beyond the personal and socioeconomic impact caused by migraine, obesity and DM, it has been suggested that these metabolic disorders seem to be related to migraine since: (i) they are a risk factor for developing cardiovascular disorders or chronic diseases; (ii) they can be influenced by genetic and environmental risk factors; and (iii) while clinical and epidemiological studies suggest that obesity is a risk factor for migraine, DM (i.e., type 1 and type 2 DM) have been reported to be either a protective or a risk factor in migraine. On this basis, and given the high worldwide prevalence of migraine, obesity, and DM, this article provides a narrative review of the current literature related to the association between the etiology and pathophysiology of migraine and these metabolic disorders, considering lifestyle aspects, as well as the possible involvement of neurotransmitters, neuropeptides, and/or sex hormones. While a link between migraine and metabolic disorders has been suggested, many studies are contradictory and the mechanisms involved in this association are not yet sufficiently established. Therefore, further research should be focused on understanding the possible mechanisms involved.

Abstract
Epilepsy is a complex brain disorder characterized by repetitive seizure events. Epilepsy patients often suffer from various and severe physical and psychological comorbidities (e.g., anxiety, migraine, and stroke). While general comorbidity prevalences and incidences can be estimated from epidemiological data, such an approach does not take into account that actual patient-specific risks can depend on various individual factors, including medication. This motivates to develop a machine learning approach for predicting risks of future comorbidities for individual epilepsy patients. In this work, we use inpatient and outpatient administrative health claims data of around 19,500 U.S. epilepsy patients. We suggest a dedicated multimodal neural network architecture (Deep personalized LOngitudinal convolutional RIsk model-DeepLORI) to predict the time-dependent risk of six common comorbidities of epilepsy patients. We demonstrate superior performance of DeepLORI in a comparison with several existing methods. Moreover, we show that DeepLORI-based predictions can be interpreted on the level of individual patients. Using a game theoretic approach, we identify relevant features in DeepLORI models and demonstrate that model predictions are explainable in light of existing knowledge about the disease. Finally, we validate the model on independent data from around 97,000 patients, showing good generalization and stable prediction performance over time.

Evaluation of body composition in patients with migraine on prophylactic treatment with topiramate. Heliyon 2021; 7:e06865.

Abstract
Migraine is a primary headache with high prevalence in the general population but is considered a disabling medical condition. It is suggested that obesity is a risk factor for chronic migraine. Thus treatment with drugs, such as topiramate, which reduces pain and weight, is ideal for obese patients with migraine. The aim of this study was to evaluate the effects of topiramate on body composition in patients with chronic migraine and to verify whether these effects could be related to nutritional status. We studied 26 female patients with age ranging from 18 to 45 years with prophylactic treatment with topiramate (50 mg/day) for three months. Body composition indexes (body mass index, BMI; body fat, BF; fat-free mass, FFM) were obtained through anthropometric assessment. After treatment, topiramate reduced BMI (0,82 kg/m2) and in BF (3.3 %), but increased FFM (1.1 kg). When considering nutritional status, FFM was increased only in obese patients. In conclusion, our main finding is that besides the reduction in BMI and BF, topiramate led to an increase in FFM in overweight and obese patients. Our results open new perspectives for future studies on the relationship between body composition and migraine, indicating that more studies on this body compartment are needed, especially in patients with chronic migraine.

Abstract
Ischemic stroke is a leading cause of death and disability worldwide. The only pharmacological treatment available to date for cerebral ischemia is tissue plasminogen activator (t-PA) and the search for successful therapeutic strategies still remains a major challenge. The loss of cerebral blood flow leads to reduced oxygen and glucose supply and a subsequent switch to the glycolytic pathway, which leads to tissue acidification. Carbonic anhydrase (CA, EC 4.2.1.1) is the enzyme responsible for converting carbon dioxide into a protons and bicarbonate, thus contributing to pH regulation and metabolism, with many CA isoforms present in the brain. Recently, numerous studies have shed light on several classes of carbonic anhydrase inhibitor (CAI) as possible new pharmacological agents for the management of brain ischemia. In the present review we summarized pharmacological, preclinical and clinical findings regarding the role of CAIs in strokes and we discuss their potential protective mechanisms.

Abstract
Since the recognition of angiotensin-converting enzyme inhibitors (ACEIs)-induced cough, drug has been considered as a potential cause of chronic cough. This review presents recent knowledge on drug-induced coughs in patients with chronic cough. The focus is placed on ACEIs, for which there are a multitude of studies documenting their associations with cough. Additional drugs are discussed for which there are reports of cough as a side effect of treatment, and the potential mechanisms of these effects are discussed.

Abstract
Children and adolescents with recurrent or chronic pain and headache are a complex and heterogenous population. Patients are best served by multi-specialty, multidisciplinary teams to assess and create tailored, individualized pain treatment and rehabilitation plans. Due to the complex nature of pain, generalizing pharmacologic treatment recommendations in children with recurrent or chronic pains is challenging. This is particularly true of complicated patients with co-existing painful and psychiatric conditions. There is an unfortunate dearth of evidence to support many pharmacologic therapies to treat children with chronic pain and headache. This narrative review hopes to supplement the available treatment options for this complex population by reviewing the pediatric and adult literature for analgesic properties of medications that also have psychiatric indication. The medications reviewed belong to medication classes typically described as antidepressants, alpha 2 delta ligands, mood stabilizers, anti-psychotics, anti-sympathetic agents, and stimulants.

Abstract
BACKGROUND Pharmacological treatment of cluster headache constitutes the core of clinical management, but evidence is sparse. We aimed to generate insight in the existing treatment and identify associations between clinical features and treatment response. METHODS Patients aged 18-65 diagnosed with cluster headache according to the ICHD-2 completed a questionnaire followed by a structured interview. Multiple logistic regression was used to identify associations. RESULTS The population consisted of 400 patients with an episodic: chronic ratio of 1.7:1. Episodic patients were more likely to respond to triptans (odds ratio = 1.77, confidence interval: 1.08-2.91, p = 0.023) and oxygen (odds ratio = 1.64, confidence interval: 1.05-2.57, p = 0.031) than chronic. Oxygen response was less likely if pain intensity was very severe (odds ratio = 0.53, confidence interval: 0.33-2.57, p = 0.006) and the risk of a poor response increased with disease duration (odds ratio = 0.79, confidence interval: 0.65-0.96, p = 0.016). Among current users of sumatriptan injection and oxygen, the proportion achieving 100% relief was higher with sumatriptan injection (p > 0.001) than with oxygen. No associations were identified regarding verapamil. Only 57% of current users of preventive medication responded at a 50% level. CONCLUSION Episodic cluster headache is more responsive to acute therapy than chronic. Further, sumatriptan injection was more effective than oxygen and the responder-rate was limited with verapamil. More effective acute and preventive therapies are needed for cluster headache patients.

Abstract
Objective:The aim of this study is to critically analyze the evidence of the efficacy and safety of greater occipital nerve (GON) block for the preventive treatment of chronic migraine (CM).Background:A rigorous scientific assessment of efficacy and safety of the GON block for preventive treatment in CM is not available. This critical review was undertaken for this purpose.Methods:References for this review were identified by searches of articles published in the English language in PubMed between 1969 and April 15, 2020 using “greater occipital nerve block,” “chronic migraine,” “migraine,” “headache,” and “treatment” as keywords.Results:Out of potential 532 articles, 9 open-label and 4 placebo-controlled trials that studied the role of GON block for prevention of CM were identified and reviewed. Open-label trials reported a reduction of headache severity and frequency in 35–68% of patients. The beneficial effect of a single block lasted up to 4 weeks. Randomized controlled trials (RCTs) used varied methodology and techniques of GON block and the outcomes were reported at different time points. A single RCT showed a beneficial effect of the GON block at 1 week. However, the GON block was found to be safe and well tolerated.Conclusion:Long-term efficacy of GON block in CM shall need further well-designed RCTs using standardized methodology. This study, in addition, reviewed the limitations and uncertainties regarding the technique and methods of use of GON block in CM.

Abstract
Background: Chronic migraine (CM) poses a significant burden for patients, and it has multiple diagnostic and managemental challenges, particularly among primary health-care physicians (PCPs). Objectives: The objective of this study is to assess the levels of knowledge regarding CM diagnosis and management among PCPs and to explore the factors associated with poor knowledge. Methods: A cross-sectional study was conducted among PCPs working at primary health-care centers in Jeddah, Saudi Arabia. A semi-structured questionnaire comprising 20 items related to CM diagnosis and treatment was used. Results: A total of 136 PCPs responded (aged 36.4 ± 8.1, 68.4% were females). The overall median (P75) knowledge score was 13.0 (15.0), and 45.6% of the participants had adequate knowledge (score > median). The majority of respondents (>50%) could not identify the lower limits of CM duration, the necessity of identifying at least eight migraine attacks in a month, the importance of managing medication overuse, and the indication of topiramate as the most efficacious agent in CM. Young physicians (23–35 years), bachelor graduates, general practitioners (GPs), and those having ≤5 years of experience scored lower than their peers. Physicians with 6–10 years of clinical experience were independently more knowledgeable than less-experienced PCPs (odds ratio = 5.09, P = 0.006). Conclusion: Knowledge regarding CM diagnosis and treatment was inadequate among PCPs, which could detrimentally influence the patterns of referral to secondary health-care facilities. Given these observations, it is recommended to amend the academic curricula for medical students/GPs and adopt continuing medical education programs for PHPs to support their levels of knowledge.

Abstract
BACKGROUND erenumab was safe and effective in clinical trials for the prevention of migraine. However, real-life data are still lacking. Here we report the clinical experience from an Italian real-world setting using erenumab in patients with chronic migraine experiencing previous unsuccessful preventive treatments. METHODS Seventy patients with chronic migraine and failure to ≥4 migraine preventive medication classes initially received monthly erenumab 70 mg s.c. Patients without a clinically meaningful improvement, considered as a > 30% reduction in headache days per month, after ≥3 months of therapy switched to monthly erenumab 140 mg. At the first administration and after 3 and 6 months, patients underwent extensive interviews to assess clinical parameters of disease severity and migraine-related disability and impact, and validated questionnaires to explore depression/anxiety, sleep, and quality of life (QoL). Finally, the Pain Catastrophizing Scale, Allodynia Symptom Checklist-12 and MIGraine attacks-Subjective COGnitive impairments scale (MIG-SCOG) were administered. RESULTS 70% of patients were "responders" after the third administration of erenumab 70 mg, whereas 30% switched to erenumab 140 mg; 29% (6 pts) responded after the sixth administration. The headache-day frequency was reduced from 21.1 ± 0.7 to 11.4 ± 0.9 days after the third administration (p < 0.001) and to 8.9 ± 0.7 days after the sixth administration (p < 0.001). 53% and 70% of patients, respectively, showed a reduction of ≥50% of headache days/month after the third and the sixth administrations. Also improved were headache pain severity, migraine-related disability, and impact on daily living, QoL, pain catastrophizing and allodynia (all p < 0.001), quality of sleep, symptoms of depression or anxiety (p < 0.05) but not MIG-SCOG. There were no new adverse event signals. CONCLUSION These real-world data support monthly erenumab 70 or 140 mg s.c. as a safe and effective preventive treatment to reduce headache frequency and severity in chronic migraine patients experiencing previous unsuccessful preventive treatments.

Abstract
Migraine headache is a common, chronic, debilitating disease with a complex etiology. Current therapy for migraine headache comprises either treatments targeting acute migraine pain or prophylactic therapy aimed at increasing the length of time between migraine episodes. Recent evidence suggests that calcium gene-related peptide (CGRP) is a critical component in the pathogenesis of migraines. Fremanezumab, a monoclonal antibody against CGRP, was recently approved by the Food and Drug Administration (FDA) after multiple studies showed that it was well-tolerated, safe, and effective in the treatment of migraines. Further research is needed to elucidate the long-term effects of fremanezumab and CGRP-antagonists in general, and additional data is required in less healthy patients to estimate its effects in these populations and potentially increase the eligible group of recipients. This is a comprehensive review of the current literature on the efficacy and safety of fremanezumab for the treatment of chronic migraine. In this review we provide an update on the epidemiology, pathogenesis, diagnosis, and current treatment of migraine, and summarize the evidence for fremanezumab as a treatment for migraine.

Abstract
Testicular torsion is a common urologic emergency and one of the causes of genital injury in males. Hence, early diagnosis and treatment are necessary to prevent testicular damage and infertility. It has been proved that topiramate (TPM) a medication used to treat epilepsy and prevent migraines has anti-inflammatory and anti-oxidative effects. Therefore, this study was designed to determine the influence of TPM on ischemia/reperfusion injury following testicular torsion/detorsion (T/D). Thirty-six male Wistar rats were divided into three groups (n = 12 for each group) including sham operated, T/D + vehicle, T/D + TPM(100 mg/kg, 30 min before detorsion). Testicular torsion was induced for 1 h by rotating right testis 7200 in the clockwise direction. After 5 h of reperfusion the testis was removed and histological changes and biochemical markers such as superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) and levels of malondialdehyde (MDA) and reduced glutathione (GSH) were evaluated. MDA level significantly increased and GSH level significantly decreased after T/D compared to the sham group (p < 0.001). Moreover, after inducing testicular T/D, GPx, CAT and SOD activity were decreased, whereas administration of TPM significantly increased GSH level and GPx, CAT and SOD activities and decreased MDA level in testis tissue as compared to T/D group. After induction of T/D, histopathological evaluations also revealed severe testicular damages which were improved by TPM administration. Our results indicate that TPM had an ameliorating impact on ischemia/reperfusion injury in the rat model of testicular T/D. This protective effect was most likely induced by anti-oxidative properties of this drug.

Abstract
Abstract
Study Objectives
Sleep-related eating disorder (SRED) is a parasomnia characterized by partial arousals from sleep with compulsive consumption of food with impaired level of awareness and memory for the event. Small case series’ have demonstrated efficacy of topiramate in SRED. We conducted a placebo-controlled randomized clinical trial of topiramate to assess efficacy in SRED.
Methods
Thirty-four participants with an ICSD-2/ICSD-3 diagnosis of SRED with >6 months of symptoms and ≥3 sleep-related eating episodes per week were randomized to placebo or topiramate with flexible dosing to a maximum dosage of 300 mg for 13 weeks. Primary outcomes were percentage of nights with eating and Clinician Global Impression-Improvement (CGI-I). Intention-to-treat last observation carried forward (ITT LOCF) analysis was conducted.
Results
Mean age was 39.5 years, 74% were female, with mean duration of sleep-related eating of 13.7 years. SRED symptoms were significantly reduced with topiramate (74.7% to 33.2% nights/week; n = 15) compared to placebo (77.0% to 57.4%; n = 17) (p = 0.035). There were significantly more CGI-I responders on topiramate (71%) than placebo (27%) (p = 0.016). Level of wakefulness (r = −0.49) and memory for nighttime eating (r = −0.58) at baseline predicted topiramate response. The topiramate group lost significantly more weight than the placebo group (−8.5 lbs vs. +1.0 lbs, p = 0.001). The most common side effects were paresthesias and cognitive dysfunction.
Conclusions
This first randomized controlled trial demonstrating efficacy for treatment of SRED supports preliminary data on the use of topiramate for SRED. Side effects were prominent for topiramate. Limitations include a small sample size and a high drop-out rate in both study groups.

Trajectory of migraine-related disability following long-term treatment with lasmiditan: results of the GLADIATOR study. J Headache Pain 2020; 21:20.

Abstract
BACKGROUND Migraine is recognized as the second leading cause of disability globally. Lasmiditan is a novel, selective serotonin 5-HT1F receptor agonist developed for acute treatment of migraine. Here we analyzed effects of lasmiditan on migraine disability assessed with the Migraine Disability Assessment (MIDAS) scale for interim data from a long-term safety study. METHODS Completers of two single-attack parent studies were offered participation in the 1 year GLADIATOR study, that randomized participants to treatment with lasmiditan 100 mg or 200 mg taken as needed for migraine attacks of at least moderate severity. Changes in MIDAS were modeled using a mixed model repeated measures analysis. RESULTS The sample included 1978 patients who received ≥1 lasmiditan dose and were followed for a median of 288 days. Baseline mean MIDAS scores for the lasmiditan 100-mg and 200-mg groups were 29.4 and 28.9, respectively, indicating severe migraine-related disability. Relative to baseline, MIDAS total scores were significantly lower at 3, 6, 9, and 12 months for both dose groups. At 12 months, changes in MIDAS scores were - 12.5 and - 12.2 for lasmiditan 100 mg and 200 mg, respectively, with 49% and 53% of patients, respectively, achieving at least a 50% decrease in MIDAS total score. Statistically significant improvements were also seen for work and/or school absenteeism and presenteeism, monthly headache days, and mean headache pain intensity at all time points up to 1 year. Findings for patients who completed all visits versus those dropping out early were similar. Responses were generally similar for the lasmiditan 100 mg or 200 mg doses, between subgroups defined based on the number of baseline monthly migraine attacks (≤5 vs. >5), and also between subgroups defined by pain-free response (yes/no) during initial attacks. CONCLUSIONS Long-term treatment with lasmiditan was associated with significant reductions in migraine-related disability, including both work or school absenteeism and presenteeism. The similarity of responses in completers and those who dropped out suggests that selective attrition does not account for the improvements. Benefits were significant at 3 months and maintained through 12 months. TRIAL REGISTRATION clinicaltrials.govNCT02565186; first posted October 1, 2015.

Abstract
Alcohol use disorder (AUD) and chronic pain are enduring and devastating conditions that share an intersecting epidemiology and neurobiology. Chronic alcohol use itself can produce a characteristic painful neuropathy, while the regular analgesic use of alcohol in the context of nociceptive sensitization and heightened affective pain sensitivity may promote negative reinforcement mechanisms that underlie AUD maintenance and progression. The goal of this review was to provide a broad translational framework that communicates research findings spanning preclinical and clinical studies, including a review of genetic, molecular, behavioral, and social mechanisms that facilitate interactions between persistent pain and alcohol use. We also consider recent evidence that will shape future investigations into novel treatment mechanisms for pain in individuals suffering from AUD.

Abstract
OBJECTIVE To review the published findings relevant to migraine and driving performance, with an intent to encourage discussion on research which may broaden understanding in this area and help educate healthcare providers and their patients. BACKGROUND Motor vehicle crashes result in more than 35,000 deaths and more than 2 million injuries annually in the United States. Migraine is one of the most prevalent diseases in the world, and many symptoms associated with migraine attacks have the potential to negatively influence driving ability. METHODS We reviewed the published findings related to migraine and driving performance. Study findings relevant to symptoms of migraine and their potential effect on driving were also reviewed. This required a more expansive exploration of the literature beyond migraine, for example, review of the literature relating to the effect of pain, sleepiness, visual disturbances, or vertigo on driving. Finally, the potential effects of treatment for migraine on driving were reviewed. RESULTS Literature on the effect of migraine on driving performance is sparse and, in general published studies on the topic have a number of limitations. Based on review of the literature pertaining to other disorders, it seems feasible that some symptoms occurring as part of the migraine attack could impact driving performance, although formal study in this area is lacking. Many of the approved treatments for migraine have the potential to impact driving, yet this has not been specifically studied, and the extent to which these risks are communicated to patients is not clear. CONCLUSION The impact of migraine on driving performance has been largely neglected, with few studies specifically designed to address the topic, and relevant studies were generally small with limited control of confounders. This area requires more focus, given a potential for impact on road safety.

Abstract
Background: Migraine is the most common acute primary headache in children and adolescents. In 2014, topiramate became the first preventive drug for migraine, approved by the Food and Drug Administration (FDA) for adolescents. This meta-analysis was aimed to evaluate the efficacy and safety of topiramate in the prevention of pediatric migraine. Methods: We searched the PubMed, EMBASE, Cochrane Library, and Chinese National Knowledge Infrastructure (CNKI) databases up to June 2019 for eligible randomized controlled trials (RCTs). The primary outcomes were mean migraine days per month, ≥50% reduction rate, and Pediatric Migraine Disability Assessment Scale (PedMIDAS) scores. RevMan5.3 software was performed for statistical analysis. Results: Overall, 5 RCTs recruiting 531 patients (6-17 years of age) were included in the meta-analysis. The target dose of topiramate was 2 mg/kg (the maintenance phase was 12 weeks), 2-3 mg/kg, 50 mg/day, and 100 mg/day (maintaining for 16 weeks), respectively, in the included studies. Our results demonstrate that participants receiving topiramate had a significant advantage in remitting the monthly migraine days than those receiving placebo, with a mean difference (MD) of -0.78 (n = 531; 95% CI, -1.23 to -0.32; Z = 3.37; P = 0.0008). Topiramate could also reduce the mean PedMIDAS scores (n = 238; 95% CI, -16.53 to -0.49; Z = 2.43; P = 0.04). However, there was no significant difference in the percentage of patients experiencing a ≥50% reduction in monthly headache days between topiramate and placebo groups (n = 531; 95% CI, 0.94-1.77; Z = 1.58; P = 0.11). Topiramate was associated with higher rates of side effects such as weight decrease (n = 395; 95% CI, 2.73-22.98; Z = 3.81; P < 0.01) and paresthesia (n = 531; 95% CI, 3.05-13.18; Z = 4.94; P < 0.01). Conclusions: Topiramate can significantly decrease monthly headache days and migraine-related burden in migraine patients <18 years old. However, it failed to increase 50% response rate. Adverse events seem to be more frequent in topiramate-treated children.

Onabotulinumtoxin-A in Chronic Migraine: Should Timing and Definition of Non-Responder Status Be Revised? Suggestions From a Real-Life Italian Multicenter Experience. Headache 2019; 59:1300-1309.

Abstract
OBJECTIVE To clarify whether the clinical response after the first 2 cycles with Onabotulinumtoxin A can accurately predict the long-term response. BACKGROUND Onabotulinumtoxin-A (OBT-A) is an approved preventive treatment option for chronic migraine (CM). Nowadays, it remains to be clarified if the treatment has to be prolonged for at least an entire year (4 injections every 3 months - ie, quarterly, as proposed in the PREEMPT trials) or it can be halted after the second or third injection if not clinically effective. DESIGN AND METHODS We conducted a multicenter observational cohort study based on real-life data on the usage of OBT-A in CM patients from 2 Italian headache centers, Roma Campus Bio-Medico and Milano Besta, adopting the whole 4-injections protocol. We performed a retrospective analysis of medical records of consecutive patients treated in the 2 centers. The main statistical analysis aimed to evaluate longitudinal measures related to headache (monthly headache frequency, monthly number of analgesic drugs, MIDAS). We hypothesized from our clinical practice with OBT-A that only 2 cycles of treatment were not enough to actually define the non-responder status to botulinum toxin A and that probably a longer time of treatment is needed to get the condition of long-term (delayed) responder. RESULTS We considered 115 patients from the 2 centers: 53 in Roma and 62 in Milano. Regarding the main analysis, a clear improvement in each measure was obtained at the 6 months assessment and maintained up to 12 months. Comparing patients with <30% and ≥30% reduction in headache frequency between T0 and T2 or T4 (respectively, "Non-Responders" and "Responders"), we found that the agreement between the classification Responders/Non-Responders at T2 and T4 was not very high (79/104 = 76.0%, with a "moderate" Cohen's Kappa of 0.51), suggesting that the status at T4 is not fully predictable by the status at T2 (λ = 0.47). Responders for headache frequency at T4 were 54.8%. Among Responders at T2, Responders at T4 were 47/62 = 75.8% (95% CI: 64.5%, 85.5%), while among Non-Responders at T2, Responders at T4 were 10/42 = 23.8% (95% CI: 11.9%, 38.1%). Similarly, even when considering the 50% reduction in painkillers consumption or in MIDAS total score between T0 and T2 as possible prognostic factors, the changes occurring at T4 are not strongly predictable by those at T2. CONCLUSIONS A ≥30% reduction in headache frequency at T2 cut-off is not adequate in predicting a late response to treatment: more than a quarter of excluded patients would miss a clinical improvement with an ongoing treatment, while in a similar percentage of Responders the treatment would lose efficacy. Results from our real-life study suggest that we possibly have to postpone the definition of Responder/Non-Responder to OBT-A at least after 1 year of treatment (4 cycles).

Abstract
Episodic migraine is a debilitating condition. Preventive therapy is used to reduce frequency, duration, or severity of attacks. This review discusses principles of preventive treatment with a focus on preventive treatment options for people with episodic migraine. Specifically discussed is evidence and use of new migraine-specific treatment options for episodic migraine, such as calcitonin gene-related peptide monoclonal antibodies, a noninvasive transcutaneous electrical nerve stimulation device, and a single-pulse transcranial magnetic stimulator device. Also discussed are evidence-based updates from the 2012 American Academy of Neurology and the American Headache Society guidelines regarding major medication classes recommended for preventive episodic migraine treatment.
