Assessing the Long-Term (48-Week) Effectiveness, Safety, and Tolerability of Fremanezumab in Migraine in Real Life: Insights from the Multicenter, Prospective, FRIEND3 Study.

INTRODUCTION: Long-term (1-year) fremanezumab treatment proved to be effective, safe, and well tolerated in individuals with migraine and < 2 medication clusters in a randomized controlled trial (RCT). We aimed to assess real-world evidence (RWE), long-term effectiveness, tolerability, and safety of fremanezumab in people with high-frequency episodic migraine (HFEM) or chronic migraine (CM) with > 3 treatment failures and various comorbidities. METHODS: A 48-week, prospective, multicenter (n = 26), cohort study assessed fremanezumab's effectiveness, safety, and tolerability in consecutive adults with HFEM or CM with > 3 treatment failures. Primary endpoint was variation from baseline in monthly migraine days (MMD) in HFEM and monthly headache days (MHD) in CM at weeks 45-48. Secondary endpoints were changes in monthly analgesic medications, Numerical Rating Scale (NRS), Headache Impact Test (HIT-6), and the Migraine Disability Assessment Scale (MIDAS) scores and ≥ 50%, ≥ 75%, and 100% responder rates. RESULTS: Of 533 participants who had received ≥ 1 fremanezumab dose, 130 were treated for ≥ 48 weeks and considered for effectiveness analysis. No participant missed any treatment dosage every other consecutive month during the 12-month period. PRIMARY ENDPOINT: fremanezumab significantly (p < 0.001) reduced both MMD (- 6.4) in HFEM and MHD (- 14.5) in CM. Secondary endpoints: a significant reduction (p < 0.001) was observed in monthly analgesic medications (HFEM - 6.0; CM -16.5), NRS (HFEM - 3.4; CM - 3.4), HIT-6 (HFEM - 16.9; CM - 17.9) and MIDAS score (HFEM - 50.4; CM - 76.6). The ≥ 50%, ≥ 75%, and 100% response rates to fremanezumab were 75.5%, 36.7%, and 2% in HFEM and 71.6%, 44.4%, and 3.7% in CM. Corresponding response rates were 60.5%, 37.2%, and 2.3% in individuals with psychiatric comorbidities, 74.2%, 50%, and 4.8% in CM with medication overuse, and 60.9%, 39.1%, and 4.3% in CM with medication overuse and psychiatric comorbidities. Mild and transient treatment-emergent adverse events occurred in 7.8% of the participants. No subject discontinued the treatment for any reason. CONCLUSION: This RWE study documents that long-term fremanezumab treatment is highly effective and remarkably well tolerated in subjects with HFEM or CM with multiple (> 3) therapeutic failures, even in the presence of concomitant medication overuse, psychiatric comorbidities, or both. The effectiveness-to-tolerability ratio appears to be better in RWE than in RCTs.

Erenumab and Possible CGRP Effect on Chronotype in Chronic Migraine: A Real-Life Study of 12 Months Treatment.

The introduction of monoclonal antibodies (mAbs) directed against the calcitonin gene-related peptide (CGRP), or its receptor (CGRPr), revolutionized migraine management due to their high efficacy and few side effects. Data suggest that the CGRP may even be implicated in circadian rhythm, but studies about the effect of anti-CGRP treatments on sleep are still lacking. The aim of the present study was to assess the effect of erenumab (70 and 140 mg per month), a human mAb directed against CGRPr, on chronotype in chronic migraineurs; secondly, we assessed its efficacy, safety, and the effects on anxiety and depression. Sleep was evaluated using self-administrable questionnaires investigating chronotype, sleep quality, and daytime sleepiness. Migraine diaries and several self-administrable questionnaires regarding headache impact and psychological correlates were evaluated every 3 months during 12 months of treatment. Eighty-eight patients were included; most of them showed a significant reduction in headache frequency and an improvement in psychological symptoms. Moreover, an initial change in chronotype was observed at the three-month assessment from a morning chronotype to an intermediate one; a similar trend remained in the other evaluations, even if it did not reach a statistical significance. Lastly, patients who responded to the treatment showed a progressive sleep efficiency reduction. The present real-life study hypothesized the influence of erenumab on chronotype, representing a link between circadian rhythm, CGRP, and migraine.

Early and sustained efficacy of fremanezumab over 24-weeks in migraine patients with multiple preventive treatment failures: the multicenter, prospective, real-life FRIEND2 study.

BACKGROUND: To verify the long-term (24-week) efficacy, safety, and tolerability of fremanezumab in real-life patients with high-frequency episodic migraine (HFEM: ≥ 8 days/month) or chronic migraine (CM: ≥ 15 days/month), and multiple preventive treatment failures. METHODS: This is a prospective, cohort, real-life study at 28 headache centers on consecutive patients affected by HFEM or CM with multiple preventive treatment failures who were prescribed subcutaneous fremanezumab (225 mg monthly/675 mg quarterly) for ≥ 24 weeks. Primary endpoint was the change in monthly migraine days (MMDs) in HFEM and monthly headache days (MHDs) in CM at weeks 21-24 compared to baseline. Secondary endpoints encompassed changes in monthly analgesic medications, ≥ 50%, ≥ 75%, and 100% responder rates, and variation in NRS, HIT-6 and MIDAS scores at the same time interval. Changes in MMDs/MHDs, monthly analgesic medications, ≥ 50%, ≥ 75%, and 100% responder rates, and variation in NRS and HIT-6 scores at week 4 were also monitored. RESULTS: Four hundred ten patients who had received ≥ 1 dose of fremanezumab were considered for safety analysis while 148 patients treated for ≥ 24 weeks were included in the efficacy analysis. At weeks 21-24, fremanezumab significantly (p < 0.001) reduced MMDs, MHDs, monthly analgesic medications and NRS, HIT-6, and MIDAS scores in both HFEM and CM compared to baseline. The proportions of ≥ 50%, ≥ 75% and 100% responders at weeks 21-24were 75.0%, 30.8%, 9.6% (HFEM), and 72.9, 44.8 and 1% (CM). A significant (p < 0.001) decrease in MMDs, MHDs, monthly analgesic medications and NRS, HIT-6, and MIDAS scores in both HFEM and CM was already present at week 4. The proportions of ≥ 50%, ≥ 75%, and 100% responders at week 4 were 67.6%, 32.4%, 11.8% (HFEM) and 67.3%, 40%, 1.8% (CM). CM remitted to episodic migraine and medication overuse to no-medication overuse in 83.3 and 75% of patients at week 24, and in 80 and 72.4% at week 4. Adverse events were rare (2.4%), mild and transient. No patient discontinued treatment for any reason. CONCLUSIONS: Fremanezumab is characterized by an early and sustained efficacy in HFEM and CM patients with multiple preventive treatment failures in real-life, revealing an optimal safety and tolerability profile.

Sleep and sleep-modifying factors in chronic migraine patients during the COVID-19 lockdown.

AIMS: The objective of the present study was to evaluate sleep features and sleep-modifying factors in patients with chronic migraine (CM) during the first Italian COVID-19 lockdown. MATERIAL AND METHODS: The study was based on an e-mail survey addressed to CM patients of our headache center. The survey investigated demographic, life-style, sleep, psychological, and migraine features during the first COVID-19 lockdown period and the month before. The outcomes were sleep quality (measured using PSQI) and variation in sleep quality, duration, and latency. RESULTS: Ninety-two patients were included. The mean PSQI was 11.96. Sleep quality was improved in 14.1%, stable in 47.8%, and worsened in 38.0%. Sleep latency was reduced in 5.4%, stable in 46.7%, and increased in 47.8%. Sleep duration was reduced in 29.3%, stable in 34.8%, and increased in 35.9%. Significant associations were found with age, work/study, remote working, job loss, meal quality change, smoking variation, COVID-19 province prevalence, home-inhabitant relationship, ratio of house size/number of people, stress, state anxiety, anxiety/depression variation, future concern variation, computer hours, internet hours, and television hours. CONCLUSION: The study described sleep features of chronic migraineurs during COVID-19 lockdown, pinpointing the main factors involved in sleep quality and sleep changes. Our findings revealed that migraineurs' sleep was closely linked with life-style and psychological features. Several modifiable factors came to light and they should be considered in order to develop an optimal management of CM. An appropriate and more aware treatment of sleep problems could be a way to improve migraineurs' life.

Chronic migraine in the first COVID-19 lockdown: the impact of sleep, remote working, and other life/psychological changes.

AIMS: The objective of this study was to evaluate the impact of the first Italian COVID-19 lockdown on patients with chronic migraine (CM). MATERIAL AND METHODS: The study was based on an e-mail survey addressed to CM patients of our headache center. The survey evaluated demographic, life style, sleep, psychological, and migraine features during the COVID-19 lockdown period and the month before. The outcomes were migraine impact on daily life and variation in attack frequency, attack duration, migraine pain intensity, migraine symptomatic drugs use per week, and efficacy. RESULTS: Ninety-two patients completed the survey. During the lockdown period, attack frequency was stable in 40,2%, increased in 33,7%, and reduced in 26,1% of patients; attack duration was stable in 55,4%, increased in 23,9%, and reduced in 20,7%. Migraine pain was stable or reduced in 65,2% and increased in 34,8%; number of symptomatic drugs per week was stable in 50%, reduced in 29,3%, and increased in 20,7%; migraine drug efficacy was stable in 73,9%, reduced in 17,4%, and increased in 8,7%. Patients had a HIT-6 score of 64,63 ± 8,81. Significant associations were found with remote working, smoke, education, discontinuation of the therapy performed within headache center, migraine familiarity, sleep, anxiety, perceived stress, concern about future, and COVID-19. CONCLUSION: During the lockdown, approximately half of the patients had a clinical stability, a quarter an improvement, and another quarter a worsening. We identified different migraine-influencing elements; in particular, the remote working could represent an easy way to ameliorate migraineurs' life.

Favourable course in a cohort of Parkinson's disease patients infected by SARS-CoV-2: a single-centre experience.

The COVID-19 outbreak has had a dramatic impact on the healthcare system due to the rapid, worldwide spread of the virus, highlighting several considerations on the best management of infected patients and also potential risks and prognostic factors in patients with pre-existing chronic diseases exposed to the virus. Neurodegenerative disorders are known to be chronic, disabling diseases that imply a higher vulnerability to infections, and for this reason, it has been suggested that SARS-CoV-2 infection may have a worse course in these patients. In the present study, we report our experience with 12 patients affected by Parkinson's disease (PD) who became infected with SARS-Cov-2 due to a COVID-19 outbreak in a care residency, and thus hospitalised in our COVID hospital. Most of the PD patients had a long disease duration and multiple comorbidities even though SARS-CoV-2 manifestations were mild, and none required intensive care. Despite lung conditions, most of our PD patients had mild symptoms: 7 patients were clinically asymptomatic (58.3%); 3 patients had fever, cough, and myalgia (25%) and 2 patients had dyspnoea (16%) that needed high-flow oxygen therapy. Few complications related to PD were seen. All patients were discharged after a mean hospitalisation period of 30 days. Mortality rate during hospitalisation was zero. Our findings suggest that SARS-CoV-2 infection does not have a poor prognosis in patients with PD. More extensive data and evaluations, however, are needed to confirm our data, and caution is warranted.

[Negative emotions in headache patients.] / Le emozioni negative nei soggetti cefalalgici.

INTRODUCTION: Several studies highlighted the presence of anxiety, depression and anger in headache patients, however the results are not always consistent. The aim of this work was to explore the link between the different components of anger, the level of depression, trait and state anxiety, and the diagnostic parameters such as frequency and duration of the headache attacks. MATERIALS AND METHODS: Eighty patients referred to the Headache center of Messina University Hospital G. Martino, aged between 16 and 70 years (M=40.60; DS=14.64) were evaluated with the State-Trait Anger Expression Inventory (STAXI-2), the State-Trait Anxiety Inventory (STAI), and the Beck Depression Inventory (BDI). RESULTS: Findings showed a significant positive relation between anger expression-in and the duration of the attacks (r=.488; p<.021) and between the level of depression and the frequency of the attacks (r=.323; p<.045). CONCLUSION: It is possible to suppose that targeted psychological and psychiatric treatments might directly affect on the symptomatology, improving the quality of life of patients.

Chronic inflammatory demyelinating polyneuropathy as a possible novel component of autoimmune poly-endocrine-candidiasis-ectodermal dystrophy.

We describe two unrelated boys with autoimmune poly-endocrine-candidiasis-ectodermal dystrophy syndrome (APECED) who, in addition to manifesting the most common symptoms (chronic mucocutaneous candidiasis, hypoparathyroidism and Addison's disease), developed progressive muscular weakness in both the proximal and distal limbs, sensory loss and absent tendon reflexes. Electrophysiological studies disclosed a reduction of nerve conduction velocity in both patients that was consistent with the diagnosis of chronic inflammatory demyelinating polyneuropathy (CIDP).This diagnosis was supported by histological demyelination in nerve biopsy specimens with patchy CD4, CD8 and CD68-positive cell infiltration in the first patient and increased protein content in the cerebrospinal fluid in the second patient. Our cases represent the first report of an association between APECED and CIDP, in which peripheral nerve demyelination may represent a novel disease component in APECED. Our findings highlight the need to explore apparently rare manifestations in patients with APECED.

Hypnic headache responsive to low-dose topiramate: a case report.

This is a clinical report of a 63-year-old woman, with a 3-year history of severe episodes of hypnic headache responding to low-doses of topiramate (25 mg at bedtime). Topiramate has been used at the dosage of 100 mg/day for hypnic headache prevention in one recent case report with benefit. This report confirms the efficacy of topiramate in hypnic headache even using low-dose regimen therapy.

Identification of the infant-type R631C mutation in patients with the benign muscular form of CPT2 deficiency.

Carnitine palmitoyltransferase 2 (CPT2) deficiency is the most common defect of mitochondrial fatty acid oxidation; three different clinical phenotypes have been described but the adult form, involving exclusively the skeletal muscle, is the most frequent. We describe herein 3 families where 4 individuals manifested with the adult form of CPT2 deficiency. CPT2 gene molecular analysis identified the homozygous R631C mutation, so far only reported in severe infantile cases. Our data evidenced that R631C mutation is not exclusively detected in the infantile form but it may be present in a wider spectrum of CPT2 phenotypes. These findings indirectly suggest that other modulators may influence clinical severity of CPT2 deficiency.

Osteosclerotic myeloma with spinal leptomeningitis and severe polyneuropathy: A case report.

Osteosclerotic myeloma is a rare plasma cell disorder often associated with a polyneuropathy. We describe a young patient with progressive polyneuropathy associated with vertebral bone marrow lesions and unusual meningeal infiltration at cauda level. The diagnosis of osteosclerotic myeloma was confirmed by bone marrow biopsy findings including the chromosome 13q14 deletion in 37% of the cells. Leptomeningeal involvement was demonstrated by spine magnetic resonance imaging with gadolinium administration and fat-suppression technique.
