Acute Treatment of Migraine: Expert Consensus Statements from the United Arab Emirates (UAE).

INTRODUCTION: Migraine, characterized by recurrent headaches and often accompanied by other symptoms like nausea, vomiting, and sensitivity to light and sound, significantly impacts patients' quality of life (QoL) and daily functioning. The global burden of migraines is reflected not only in terms of reduced QoL but also in the form of increased healthcare costs and missed work or school days. While UAE (United Arab Emirates)-specific consensus-based recommendations for the effective use of preventive calcitonin gene-related peptide (CGRP)-based migraine therapies have been published previously, an absence of such regional guidance on the management of acute migraine represents a gap that needs to be urgently addressed. METHODS: A task force of eight neurologists from the UAE with expertise in migraine management conducted a comprehensive literature search and developed a set of expert statements on the management of acute migraine that were specific to the UAE context. To ensure diverse perspectives are considered, a Delphi panel comprising 16 neurologists plus the task force members was set up. Consensus was achieved using a modified Delphi survey method. Consensus was predefined as a median rating of 7 or higher without discordance (if > 25% of the Delphi panelists rate an expert statement as 3 or lower on the Likert scale). Expert statements achieving consensus were adopted. RESULTS: The Modified Delphi method was used successfully to achieve consensus on all nine expert statements drafted by the task force. These consensus statements aim to provide a comprehensive guide for UAE healthcare professionals in treating acute migraine. The statements cover all aspects of acute migraine treatment, including what goals to set, the timing of treatment, treatment strategy to use in case of inadequate response to triptans, safety aspects of combining gepants for acute attacks with preventive CGRP-based therapies, special population (pregnant and pediatric patients) considerations, and the management of the most bothersome symptoms (MBS). CONCLUSIONS: Adopting these consensus statements on the treatment of acute migraine can help enhance patient care, improve outcomes, and standardize treatment practices in the UAE. The collaborative effort of experts with diverse experiences in developing these consensus statements will strengthen the credibility and applicability of these statements to various healthcare settings in the country.

Consensus-Based Recommendations on the Use of CGRP-Based Therapies for Migraine Prevention in the UAE.

INTRODUCTION: Migraine is a common debilitating neurological disorder affecting a large proportion of the general population. Calcitonin gene-related peptide (CGRP), a 37-amino acid neuropeptide, plays a key role in the pathophysiology of migraine, and the development of therapies targeting the anti-CGRP pathway has revolutionized the field of migraine treatment. METHODS: An expert task force of neurologists in the United Arab Emirates (UAE) developed and critically assessed recommendations on the use of CGRP-based therapies in migraine treatment and management in the UAE, based on available published literature. A consensus was reached for each statement by means of an open-voting process, based on a predefined agreement level of at least 60%. RESULTS: The consensus recommendations advocate the need for guidelines for the appropriate use of CGRP-based therapies by defining patient cohorts and appropriate monitoring of therapeutic response as well as standardizing the initiation, assessment, and cessation of treatment. The consensus recommendations were primarily formulated on the basis of international studies, because of the limited availability of regional and local data. As such, they may also act as guidelines for global healthcare providers. CONCLUSIONS: These are the first consensus recommendations for the UAE that address the use of CGRP-based therapies in the treatment and management of migraine, integrating both clinical evidence and medical expertise to enhance clinical judgment and decision-making.

Intracranial hypertension with polyradiculopathy--early CSF diversion to optimize neurological recovery.

Cerebral venous sinus thrombosis (CVST) and idiopathic intracranial hypertension (IIH) are common considerations in young patients presenting with isolated intracranial hypertension. We report two patients with progressive visual failure and polyradiculopathy with areflexic quadriparesis, secondary to raised intracranial pressure (ICP). Both underwent cerebrospinal fluid diversion with complete recovery. Such a fulminant presentation of raised ICP with an excellent outcome has rarely been reported in the literature.

Frequency of Cerebral Venous Thrombosis in Dubai, UAE-A Multicenter, Retrospective Study.

Background and Purpose: Cerebral venous thrombosis (CVT), also known as cerebral dural venous thrombosis, is not a very common cause of stroke. It has a diverse clinical presentation, with multiple predisposing factors and imaging findings. The incidence of CVT varies in different studies. We hypothesized that the incidence of CVT in Dubai is more than that reported in the West owing to dehydration caused by the high atmospheric temperature. Methods: We retrospectively reviewed the medical records of all patients aged more than 13 years with appropriate International Classification of Diseases, 9th Revision, codes for the diagnosis of CVT from January 1, 2010 to December 31, 2018 from three major hospitals with an acute stroke service in Dubai, United Arab Emirates. Results: We identified 138 patients who presented with CVT. The average frequency of CVT was 6.6 per 100,000 population. Fifty percent of the patients presented between May and September, which are considered the hottest months in the UAE. Headache was the most common presentation, followed by seizures. The most important risk factors were the use of oral contraceptive pills, anemia, and polycythemia. Our study showed a higher incidence of anemia, polycythemia, thrombophilia, and abnormal CT brain findings. Conclusion: In our study, CVT was more common during the months of summer. Anemia and polycythemia were strongly associated with CVT. Public awareness about CVT, its higher incidence during summer months and strategies to avoid dehydration might be considered to reduce the incidence of CVT in summer months. However, larger studies are needed to confirm definite associations.

Iatrogenic transverse myelitis in a patient with rheumatoid arthritis.

We report the case of a 59-year-old Arab woman who was presented with acute onset of neck pain followed by quadriparesis, paraesthesias of lower limbs and incontinence of urine. Examination revealed asymmetric sensorimotor quadriparesis with sensory level at T1, establishing a clinical diagnosis of transverse myelitis. Cervical and thoracic spinal MRI showed enhancing T2/fluid attenuated inversion recovery (FLAIR) hyperintense lesion extending from C4 to C7 level in addition to long-segment lesion extending the whole of the spinal cord. She was known to have rheumatoid arthritis for the past 20 years and has been on etanercept for the past 8 years and methotrexate since past 3 years. Etanercept was stopped and she was treated with methylprednisolone followed by oral steroids and physiotherapy with which she had near complete recovery.

Rescue treatment in patients with poorly responsive Guillain-Barre syndrome.

OBJECTIVES: To evaluate the effectiveness of rescue treatment (intravenous immunoglobulin or plasma exchange) in patients with Guillain-Barre syndrome who did not respond or deteriorated after the initial management with intravenous immunoglobulin. METHODS: We performed a retrospective review of the medical records of patients who responded poorly or did not respond to intravenous immunoglobulin treatment. The disability parameters of those who received second-line treatment with intravenous immunoglobulin or plasma exchange (20 patients) were compared with those who did not receive second-line treatment (19 patients). RESULTS: There was a statistically significant improvement in disability scores at 1 month in the patients who received the rescue treatment (p = 0.033). However, there was no significant difference in the disability scores at 3 and 6 months, or in length of intensive care unit stay. CONCLUSION: Our study showed that a second course of treatment to carefully selected patients may be beneficial.

Delayed presentation of neck arteries dissection, caused by water slide activity.

A 16-year-old Korean boy presented with acute onset vertigo, dysphagia and gait ataxia of 16 hours duration. He had history of headache and neck pain along with transient vertigo during a water slide ride 12 days before presentation. CT brain showed left cerebellar and left lateral medullary infarcts. CT angiography showed left vertebral dissection with occlusion of left posterior inferior cerebellar artery. A 52-year-old Indian man, presented with acute onset global aphasia and right hemiparesis within 3 hours of onset of symptoms. He received intravenous tissue plasminogen activator (tPA) with partial improvement in his symptoms. He had headache and neck pain since 2 weeks, ever since he had a water slide ride. CT brain was normal, while the CT angiogram showed left carotid dissection. Cervical artery dissection has been reported with roller coaster rides and rarely with delayed presentations. Delayed presentation of cervical artery dissection after water rides have not been reported.

Mycoplasma pneumoniae infection presenting as stroke and meningoencephalitis with aortic and subclavian aneurysms without pulmonary involvement.

A 39-year-old Philipino man presented with acute onset fever and headache. Neurological examination was normal except for neck stiffness. There was no history of chest pain, cough or breathlessness. Cerebrospinal fluid (CSF) showed a mild increase in protein with normal sugar and lymphocytic pleocytosis. CSF PCR for herpes simplex and varicella zoster virus was negative. He developed acute right haemiplegia a week after hospitalisation. MRI showed acute infarct in the left centrum semiovale. His angiogram showed aneurysm in the left subclavian artery and aortic arch. The mycoplasma antibody test came positive with very high titres, while rest of the workup was negative. He was treated with azithromycin and his symptoms improved completely.He was asymptomatic on follow-up after a month. His repeat immunoglobulin G mycoplasma antibody titre showed elevation. Mycoplasma infection is a treatable cause of meningoencephalitis and stroke secondary to vasculitis. Arterial aneurysms are known to occur with mycoplasma infection although rare.

Cerebral venous thrombosis presenting with subdural haematoma as first presentation for systemic lupus erythematosus with negative antiphospholipid antibodies.

We report the case of a 30-year-old woman, without any previous comorbidities presenting with acute onset headache, altered sensorium and unsteadiness of gait. Neurological evaluation revealed a drowsy patient with papilloedema, bilateral lateral rectus palsy, generalised hyper-reflexia and up going plantar responses. Urgent imaging performed showed extensive cortical venous sinus thrombosis. Workup for secondary causes of cortical venous sinus thrombosis revealed very high titres of antinuclear antibody and anti-dsDNA, but negative antiphospholipid antibodies (APLA). In hospital she started developing other complications of systemic lupus erythematosus (SLE). Urine evaluation revealed proteinuria and granular casts suggestive of glomerulonephritis. Cardiac evaluation revealed moderate pericardial effusion. We have discussed neurolupus as initial presentation of SLE and the rare occurrence of major neurovascular complications without secondary APLA syndrome.
