Key clinical point: Patients with migraine who achieved ≥ 50% reduction in headache days at 6 months (responders) with anti-calcitonin gene-related peptide (CGRP) monoclonal antibodies (mAb) showed an even greater reduction in the number of days per month with photophobia, phonophobia, and aura ratios.

Major finding: Monthly headache days reduced significantly by 9.4 days/month (P < .001) and 2.2 days/month (P = .004) among responders and non-responders, respectively, with responders having additional significant reductions in photophobia (−19.5%; P < .001), phonophobia (−12.1%; P = .010), and aura (−25.1%; P = .008) ratios. Higher basal photophobia ratios were predictors of increased response rates between months 3 and 6 (incidence risk ratio 0.928; P = .040).

Study details: This prospective observational study included 158 patients with migraine treated with anti-CGRP mAb, of whom 43.7% were responders.

Key clinical point: No appreciable association was observed between a history of migraine or its subtypes and an increase in the risk for COVID-19, including hospitalization for COVID-19, in older women.

Major finding: No significant association was observed between a history of migraine and the risk of developing COVID-19 (odds ratio [OR] 1.08; 95% CI 0.95-1.22) or being hospitalized for COVID-19 (OR 1.20; 95% CI 0.86-1.68) among older women. Similarly, other migraine statuses, including migraine with aura, showed no association with the risk for COVID-19.

Study details: This prospective cohort study included 16,492 women (age ≥ 45 years) enrolled in the Women’s Health Study, of whom 28.9% had a history of migraine and 7.7% reported positive SARS-CoV-2 test results, a diagnosis of COVID-19, or hospitalization for COVID-19.

Key clinical point: Absence of cutaneous allodynia was a predictor of treatment response following withdrawal therapy in patients with chronic migraine and medication overuse, with the predictive value being even more pronounced when compared with cephalic or extracephalic allodynia.

Major finding: The chances of reversion from chronic to episodic migraine were ~2.5 times higher in patients without vs with cutaneous allodynia (odds ratio [OR] 2.45; P = .042), with the predictive values of absence of allodynia being even more pronounced when compared with patients having cephalic (OR 4.16; P = .024) or extracephalic (OR 7.32; P = .003) allodynia.

Study details: This study, conducted as part of the Chronification And Reversibility of Migraine study, included 173 patients with chronic migraine and medication overuse, of whom 129 had cutaneous allodynia.

Key clinical point: A history of migraine was significantly associated with an increased risk for cervical artery dissection (CeAD), with the risk being predominantly driven by migraine without aura.

Major finding: The risk for CeAD was 1.74-fold higher in patients with vs without migraine (adjusted odds ratio [aOR] 1.74; 95% CI 1.38-2.19), with the risk being pronounced in migraine without aura (aOR 1.86; 95% CI 1.55-2.24) but not in migraine with aura (aOR 1.15; 95% CI 0.71-1.88).

Key clinical point: Early wearing-off effect (WOE) is common in patients with chronic migraine (CM) receiving onabotulinumtoxinA (OnabotA) and more frequent after the first cycle of OnabotA, with depression and anxiety disorders being clinical predictors of the WOE.

Major finding: Early WOE was reported more frequently after the first vs second treatment cycle of OnabotA (35.6% vs 23.8% of patients), with depression and anxiety disorders being significant clinical predictors of WOE (odds ratio 3.4; 95% CI 1.22-10.84; P = .028).

Study details: Findings are from a prospective real-life study including 59 patients with CM and insufficient response, absence of tolerability, or contraindications to previous migraine therapies who initiated prophylactic treatment with OnabotA, 40.6% of whom reported a WOE.

Disclosures: This study received no external funding. The authors declared no conflicts of interest.

Key clinical point: Ubrogepant shows similar efficacy and no new safety concerns for the treatment of perimenstrual migraine (pmM) and non-pmM attacks.

Major finding: At 2 hours post dose, pain freedom (P = .054) and pain relief (P = .683) were similar between pmM and non-pmM attacks treated with 50 mg ubrogepant. Absence of migraine-associated symptoms (photophobia and phonophobia) and functional disability was not significantly different between pmM and non-pmM attacks treated with 50 mg ubrogepant, with similar findings observed for 100 mg ubrogepant. Nausea and dizziness were reported in < 6% of participants overall in both the 50 mg and 100 mg ubrogepant groups.

Study details: This post hoc analysis of a long-term safety extension trial included 734 women with migraine, of whom 278 and 716 were treated with ubrogepant (50 mg or 100 mg) for ≥ 1 pmM and non-pmM attacks, respectively.

Disclosures: This study was funded by Allergan (prior to its acquisition by AbbVie). Four authors declared being employees of or holding stocks in AbbVie, and the other authors declared ties with various sources, including AbbVie.

Key clinical point: In patients with migraine, COVID-19 vaccination worsened the overall migraine symptoms in the first month post-vaccination; however, COVID-19 infection solely increased the number of acute medication intake days in the first month following infection.

Major finding: COVID-19 vaccination led to a significant increase in the number of monthly migraine days (MMD), monthly headache days (MHD), and monthly acute medication days (MAMD) by 1.06, 1.52, and 0.72, respectively (all P < .001) in the first month post-vaccination. COVID-19 infection solely increased MAMD by 1.11 (P = .027) in the first month following infection, with no significant effects on MMD and MHD.

Study details: This longitudinal cohort study identified 547 patients with migraine, of whom 147 were included in the vaccine analysis and 59 in the infection analysis.

Disclosures: This study did not receive any funding. BWH van der Arend and GM Terwindt declared receiving independent support and consultancy or industry support from various sources. The other authors declared no conflicts of interest.

Key clinical point: Pain in the lower limbs of children and adolescents, often referred to as ‘growing pain’ (GP) by pediatricians and orthopedists, can be a precursor of or a comorbidity linked to migraine.

Major finding: Overall, 76% vs 22% of children and adolescents with vs without GP experienced a primary headache disorder fulfilling the International Classification of Headache Disorders-3 diagnostic criteria for migraine (P < .001). GP persisted in 14% of patients who initially had GP and appeared in 39% of patients who were previously asymptomatic (P = .026).

Study details: This cross-sectional, prospective study included 78 children and adolescents without any headache complaints who were aged between 5 and 10 years and were born to mothers with migraine, of whom 42 experienced GP and 36 patients did not experience GP.

Key clinical point: Pain in the lower limbs of children and adolescents, often referred to as ‘growing pain’ (GP) by pediatricians and orthopedists, can be a precursor of or a comorbidity linked to migraine.

Major finding: Overall, 76% vs 22% of children and adolescents with vs without GP experienced a primary headache disorder fulfilling the International Classification of Headache Disorders-3 diagnostic criteria for migraine (P < .001). GP persisted in 14% of patients who initially had GP and appeared in 39% of patients who were previously asymptomatic (P = .026).

Key clinical point: Patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) who respond to salvage chemotherapy immediately before chimeric antigen receptor (CAR) T-cell therapy administration have better survival outcomes than those with stable or progressive disease, irrespective of the administration timing.

Major finding: Patients who did vs did not respond to salvage chemotherapy immediately before receiving CAR T-cell therapy had significantly longer overall survival rates (P < .001). The number of prior lines of salvage chemotherapy or before CAR T-cell infusion was not significantly associated with overall survival (P = .28).

Study details: This single-center, retrospective study included 76 autologous stem cell transplantation-eligible patients with relapsed or refractory DLBCL who received second-line salvage chemotherapy with curative intent, of whom 30 patients achieved partial or complete response and 34 patients (with or without response) eventually received CAR T-cell therapy.
