Social Distancing in Chronic Migraine during the COVID-19 Outbreak: Results from a Multicenter Observational Study

Background: The restrictions taken to control the rapid spread of COVID-19 resulted in a sudden, unprecedented change in people’s lifestyle, leading to negative consequences on general health. This study aimed to estimate the impact of such changes on migraine severity during 2020 March–May lockdown. Methods: Patients affected by migraine with or without aura, diagnosed by expert physicians, completed a detailed interview comprehensive of: assessment of migraine characteristics; measure of physical activity (PA) levels; measure of the intake frequency of main Italian foods; the Insomnia Severity Index (ISI) questionnaire investigating sleep disorders. Results: We included 261 patients with a mean age of 44.5 ± 12.3 years. During social distancing, 72 patients (28%) reported a headache worsening, 86 (33%) an improvement, and 103 (39%) a stable headache frequency. A significant decrease of the PA levels during COVID-19 quarantine in the whole study sample was observed (median total metabolic equivalent task (METs) decreased from 1170 to 510; p < 0.001). Additionally, a significant difference was reported on median ISI scores (from 7 to 8; p < 0.001), which were increased in patients who presented a stable or worsening headache. Conclusions: Our study confirmed that the restrictions taken during the pandemic have affected the practice of PA levels and sleep quality in migraine. Hence, PA and sleep quality should be assessed to find strategies for an improvement in quality of life.

Association between response to triptans and response to erenumab: real-life data

BackgroundTriptans and erenumab are both migraine-specific agents acting on the calcitonin gene-related peptide pathway. Therefore, response to triptans might be associated with response to erenumab.Main bodyIn our study, consecutive patients referring to the Headache Centers of the Abruzzo region from January 2019 to March 2020 and treated with erenumab were interviewed about past use and efficacy of triptans. Triptan users were classified as ‘triptan responders’ if they were headache-free 2 h after treating ≥3 migraine attacks with ≥1 triptan. We considered patients as ‘erenumab responders’, if they had a ≥ 50% mean reduction in monthly migraine days between the 4th and the 6th month from treatment start compared with baseline. Of 91 triptan users, 73 (80.2%) were triptan responders and 58 (63.7%) were erenumab responders. The odds ratio of being erenumab responder was 3.64 (95% CI, 1.25–10.64) for triptan users as compared to non-users. (P = 0.014). Besides, starting erenumab improved triptan response in both erenumab responders and non-responders.ConclusionsOur data of an association between response to triptans and response to erenumab can be useful for patient advice and to improve the understanding of migraine pathophysiology and treatment.

Background

Initial evidence have shown the short-term efficacy of sTMS in the acute and preventive treatment of migraine. It is unknown whether this treatment approach in the long-term is effective and well tolerated in difficult-to-treat migraine.

Methods

This is a prospective, single centre, open-label, real-world analysis conducted in difficult-to-treat patients with high-frequency episodic migraine (HFEM) and chronic migraine (CM) with and without medication overuse headache (MOH), who were exposed to sTMS therapy. Patients responding to a three-month sTMS treatment, continued the treatment and were assessed again at month 12. The cut-off outcome for treatment continuation was reduction in the monthly moderate to severe headache days (MHD) of at least 30% (headache frequency responders) and/or a?≥?4-point reduction in headache disability using the Headache Impact test-6 (HIT-6) (headache disability responders).

Results

One hundred fifty-three patients were included in the analysis (F:M?=?126:27, median age 43, IQR 32.3–56.8). At month 3, 93 out of 153 patients (60%) were responders to treatment. Compared to baseline, the median reduction in monthly headache days (MHD) for all patients at month 3 was 5.0?days, from 18.0 (IQR: 12.0–26.0) to 13.0?days (IQR: 5.75–24.0) (P =?0.002, r =???0.29) and the median reduction in monthly migraine days (MMD) was 4.0?days, from 13.0 (IQR: 8.75–22.0) to 9.0 (IQR: 4.0–15.25) (P =?0.002, r =???0.29). Sixty-nine out of 153 patients (45%) reported a sustained response to sTMS treatment at month 12. The percentage of patients with MOH was reduced from 52% (N =?79/153) at baseline to 19% (N =?29/153) at month 3, to 8% (N =?7/87) at month 12. There was an overall median 4-point reduction in HIT-6 score, from 66 (IQR: 64–69) at baseline to 62 at month 3 (IQR: 56–65) (P <?0.001, r =???0.51). A total of 35 mild/moderate adverse events were reported by 23 patients (15%). One patient stopped sTMS treatment due to scalp sensitivity.

Conclusions

This open label analysis suggests that sTMS may be an effective, well-tolerated treatment option for the long-term prevention of difficult-to-treat CM and HFEM.

     

InterMiG: international differences in the therapeutic approach to migraine patients in specialized headache centers

BackgroundThere is currently a wide therapeutic arsenal for migraine patients, without a single first-line preventive drug and we choose the different available alternatives taking into account comorbidities, national guidelines, previous treatments and personal experiences.Our objective was to evaluate the differences in the use of migraine treatments between neurologists from different countries.MethodsThis is a multi-centre observational study carried out by neurologists from specialized headache units in seven countries, retrospective with consecutive inclusion of all patients presenting with a migraine diagnosis, over a period of three months.ResultsA total of 734 patients were recruited but only 600 were considered in the analysis in order to homogenize the patient cohorts from countries: 200 Spain (ES), 100 Italy (IT), 85 Russia (RUS), 80 Germany (DE), 60 Portugal (PT), 45 Poland (PL) and 30 Australia (AU). 85.4 % of patients were women with a mean age of 42.6 ± 11.8 years. Considering previous and current preventive treatment, the order of use was: antidepressants (69.3 %), antiepileptic drugs (54.7 %), beta-blockers and antihypertensive drugs (49.7 %), OnabotulinumtoxinA (44.0 %) and others (36.2 %).Statistically significant differences were found between all pharmacological classes: antidepressants were commonly used in all countries, with the exception of Poland (AU: 76.7 %, IT: 71.0 %, DE: 60.0 %, PL: 31.1 %, PT: 71.7 %, RUS: 70.6 %, ES: 78.5 %; p < 0.0001); antiepileptic drugs were more frequently prescribed in Portugal, Australia and Spain (AU: 73.3 %, IT: 40.0 %, DE: 37.5 %, PL: 48.9 %, PT: 85.0 %, RUS: 29.4 % and ES: 69.0 %; p < 0.0001); beta-blockers and antihypertensive drugs were frequently used in all countries except Italy (AU: 60.0 %, IT: 14.0 %, DE: 53.8 %, PL: 48.9 %, PT: 68.3 %, RUS: 49.4 % and ES: 59.0 %; p < 0.0001); BTX-A were predominately used in Spain, Italy and Australia (AU:56.7 %, IT:58.0 %, DE:20.0 %, PL: 42.2 %, PT: 26.7 %, RUS: 24.7 % and ES: 58.5 %; p < 0.0001) and others were most frequently used in Poland (AU: 0.0 %, IT: 19.0 %, DE: 42.5 %, PL: 95.6 %, PT: 31.7 %, RUS: 3.5 % and ES: 49.5 %; p < 0.0001). If only patients without comorbidities are considered (200/600), statistically differences between countries persist in all preventive treatments.ConclusionsThere is heterogeneity in the choice of preventive treatment between different countries. Prospective comparative studies of the different oral and subcutaneous alternatives would help to create a global therapeutic algorithm that would guarantee the best option for our patients.     

Cognitive,adaptive and behavioral profile in Sotos syndrome children with 5q35 microdeletion or intragenic variants

Sotos syndrome (SoS) is a congenital overgrowth syndrome with variable degree of intellectual disability caused in the 90% of cases by pathogenetic variants of the Nuclear receptor binding SET Domain protein1 (NSD1) gene. NSD1 gene functions can be abrogated by different genetic alterations (i.e., small intragenic pathogenic variants like deletions/insertions, nonsense/missense pathogenic variants, partial gene deletions and whole deletions or microdeletion of 5q35 chromosomal region). Therefore, correlation of the genotype–phenotype with a possible contribution of more implicated genes to the medical, cognitive and behavioral profile is a topic of great interest. Although a more severe learning disability has been described in individuals with 5q35 microdeletion when compared to individuals with NSD1 intragenic pathogenic variants a fully delineated cognitive and behavioral phenotype has not been described yet. The importance of providing clinical characterization in relation to the genotype comes from the necessity to early identify children more at risk of developing psychopathological disorders. We characterize the cognitive, adaptive and behavioral phenotype of a pediatric sample of 64 individuals affected by SoS, performing a standardized neuropsychological evaluation. Secondly, we compare cognitive-behavioral profiles of SoS individuals carrying and not carrying the 5q35 microdeletion. SoS participants were characterized by a mild cognitive impairment of both Intellectual Quotient and adaptive skills in association to borderline symptoms of attention deficit. Our results suggest that the 5q35 microdeletion is associated with lower scores specifically concerning the cognitive, adaptive functioning and behavioral domains. However, longitudinal studies are necessary to confirm these findings and delineate a developmental trajectory of SoS.
