The aim of the present study was to evaluate whether previous preventive treatment with onabotulinumtoxin-A might influence subsequent clinical response following a switch to anti-CGRP monoclonal antibodies (mAbs). The present retrospective study was conducted at the Headache Centre—Neurology Clinic at the Spedali Civili Hospital of Brescia between November 2018 and May 2023. The primary objective was to assess clinical outcome (monthly headache days (MHDs), monthly migraine days (MMDs), mean analgesics consumption, and clinical disability according to Migraine Disability Assessment (MIDAS)) following three months (T3) of preventive treatment with anti-CGRP mAbs comparing patients who did and those who did not previously receive treatment with Onabotulinumtoxin-A. Moreover, we aimed to evaluate whether the clinical response to anti-CGRP mAbs was affected by the number of previous Onabotulinumtoxin-A administrations. At T3, compared to Onabotulinumtoxin-A naïve patients, patients who previously received Onabotulinumtoxin-A documented fewer MMDs (3.3 ± 3.7 versus 5.2 ± 5.0; p = 0.017) and a lower MIDAS score (23.2 ± 20.9 versus 37.4 ± 39.6; p = 0.013). Patients who received at least 3 onabotulinumtoxin-A administrations documented, at T3, lower MMDs compared to those who received fewer cycles (respectively, 2.1 ± 2.7 vs. 6.5 ± 4.4; p = 0.024). In conclusion, according to our data, previous treatment with onabotulinumtoxin-A might improve subsequent response to anti-CGRP mAbs preventive treatment.

Background: The aim of the present study was to assess the migraine outcome, in particular migraine disability, in chronic (CM) and high frequency episodic migraine (HFEM) patients in treatment with galcanezumab. Methods: The present study was conducted at the Headache Centre of Spedali Civili of Brescia. Patients were treated with galcanezumab 120 mg monthly. Clinical and demographical information were collected at the baseline (T0). Data about outcome, analgesics consumption and disability (MIDAS and HIT-6 scores) were collected quarterly. Results: Fifty-four consecutive patients were enrolled. Thirty-seven patients had a diagnosis of CM, 17 of HFEM. During treatment, patients reported a significant reduction in terms of mean headache/migraine days (p < 0.001), the attacks’ pain intensity (p = 0.001) and monthly consumed analgesics (p < 0.001). The MIDAS and HIT-6 scores also documented a significant improvement (p < 0.001). At the baseline, all patients documented a severe degree of disability (MIDAS score ≥ 21). Following six months of treatment, only 29.2% of patients still documented a MIDAS score ≥ 21, with one third of patients documenting little or no disability. A > 50% MIDAS reduction, compared to baseline, was observed in up to 94.6% of patients, following the first three months of treatment. A similar outcome was found for HIT-6 scores. A significant positive correlation was found between headache days and MIDAS at T3 and T6 (T6 > T3), but not baseline. Discussion: Monthly prophylactic treatment with galcanezumab was found to be effective in both CM and HFEM, especially in reducing migraine burden and disability.

Background: Lasmiditan, an oral 5-HT1F receptor agonist, has been recently approved for acute migraine treatment. While its efficacy was confirmed in randomized clinical trials, scarce data is available regarding effectiveness and tolerability in the real-world setting. Objectives: To evaluate lasmiditan effectiveness and tolerability in the real-world setting in 16 Italian headache centers. Design: LasmiDitan as Acute migRaine Treatment (DART) study is a prospective, multicentric, observational study. Methods: We enrolled 58 participants with migraine (84.5% females, age 49.0 (45.2–52.9) years, 24.1% with chronic migraine) reporting 9.4 (7.4–11.3) monthly migraine days. Participants were instructed to treat their migraine attacks with oral lasmiditan 50 or 100 mg. Using an ad hoc electronic diary, participants prospectively collected migraine attack features at baseline and every 30 min after lasmiditan administration, up to 2 h post-dose. The primary outcome was 2-h pain freedom for the first-treated attack after lasmiditan intake. We also collected the occurrence of treatment-emergent adverse events (AE) after administration. Results: Overall, participants treated 100 attacks, of which 58 first-treated attacks. Regarding first-treated attacks, 44.8% of subjects rated migraine intensity as severe at lasmiditan intake. Pain freedom 2-h post-dosing was reported in 32.8% (19/58) of individuals and was associated with baseline pain intensity, being higher in subjects treating a mild/moderate attack (p = 0.044). Conversely, it was not influenced by timing of intake (p = 0.375), dosage (p = 0.727), or previous triptan failure (p = 0.351). Regarding all-treated attacks, pain freedom 2-h post-dosing was 37.0% (37/100). At least one AE was reported by 53.4% of participants (31/58), predominantly asthenia, dizziness, somnolence, anxiety or agitation, and paresthesia. Tolerability was rated as good-to-excellent by 51.8% of subjects. Conclusion: Our study supports clinical effectiveness of oral lasmiditan 50 and 100 mg for the treatment of acute migraine attacks. Lasmiditan effectiveness was not associated with the previous triptan failure and may therefore represent a valuable therapeutic option in subjects who did not benefit from, or have contraindications to, triptans. Trail registration: The study was preregistered on clinicaltrial.gov, NCT05903040 (https://clinicaltrials.gov/study/NCT05903040?cond=migraine&intr=lasmiditan&rank=5).

BackgroundGiven the increasing diversity among neurological patients, standardised protocols are essential for evaluating the severity and complexity of the variety of conditions. The aim of the present work was to standardise the assessment of the severity and complexity of neurological impairment in an acute setting by using a modified version of the Neurological Impairment Scale (mNIS).MethodsConsecutively hospitalised neurological inpatients underwent a multidimensional standardised assessment of multimorbidity, frailty, functional dependency and neurological impairment using mNIS and other validated scales. Inter-rater reliability of the mNIS total and subscores was evaluated. Construct validity was assessed separately in patients with cerebrovascular disease, performing correlations between corresponding subscores of mNIS, original NIS and National Institutes of Health Stroke Scale. mNIS Complexity Index (mNIS-CI) for neurological severity was used to classify patients into subtle, mild, moderate and severe impairment.Results1081 neurological patients admitted to a neurological ward from the emergency setting were enrolled. The inter-rater reliability was remarkable for mNIS total and subscores (intraclass correlation coefficient 0.90, 95% CI 0.82 to 0.95). The mNIS showed strong construct validity for total and subscores compared with other clinical scales (r 0.47–0.97, p<0.001) and 52.7% of patients scored at least one in one of the four newly listed items. The stratification of patients according to mNIS-CI exhibited high construct validity, distinguishing the extent of impairment and involved domains.ConclusionsThe mNIS is valuable for measuring neurological severity and complexity in acute inpatients and holds significant potential for application in different settings.

Background and purpose Although there is extensive evidence about the safety of monoclonal antibodies against calcitonin gene‐related peptide (anti‐CGRP mAbs) in combination with traditional drugs, scarce data are available on the safety of their combination with other mAbs. This study aimed to evaluate the 6‐month effectiveness and tolerability of anti‐CGRP mAbs in combination with other mAbs for different diseases. Methods Patients included in the Italian Headache Registry and treated concomitantly with an anti‐CGRP mAb and another mAb were included. Effectiveness outcomes for migraine included reduction from baseline of monthly headache days (MHDs), Migraine Disability Assessment (MIDAS) score, Headache Impact Test‐6 (HIT‐6) scores, and Patients' Global Impression of Change (PGIC) scale. Adverse events (AEs) were recorded. Results Thirty‐eight patients were included. In 27 patients (71.1%), the anti‐CGRP mAb was added to a previously ongoing mAb. Nine patients (23.7%) discontinued one of the two mAbs before the end of treatment (seven discontinued the anti‐CGRP mAb and two the other mAb). One patient discontinued for AEs. Anti‐CGRP mAbs were discontinued due to ineffectiveness (n = 5, 55.5%) and one each (11.1%) for clinical remission and lost to follow‐up. MHDs significantly decreased from baseline to 3 months (p < 0.0001) and 6 months (p < 0.001), as did the MIDAS and the HIT‐6 scores at 3 and 6 months (p < 0.001). For anti‐CGRP mAbs, 27.4% of patients reported PGIC ≥ 5 at 3 months and 48.3% at 6 months. Mild AEs associated with introduction of a second mAb were detected in six patients (15.8%). Conclusions In this real‐world study, anti‐CGRP mAbs showed safety and effectiveness when administered concomitantly with other mAbs.

We performed a cross-sectional study to analyze the retinal vasculature in children, adolescent, and young adults with type 1 diabetes using optical coherence tomography angiography (OCTA). Patients underwent funduscopic examination for diabetic retinopathy (DR) screening during an annual visit for the screening of diabetes-related complications which included the evaluation of glycated hemoglobin (HbA1c), microalbuminuria, lipid profile, arterial pressure, and neurological assessment. In addition, OCTA of the retinal vasculature was performed. Quantitative analysis of the OCTA images evaluated the vessel density at the superficial (SCP) and deep (DCP) capillary plexus of the retina. Structural vascular alterations were evaluated qualitatively. Results were compared to those obtained in a group of healthy age-, sex-, and pubertal stage-matched controls. The effect of age, disease duration, age at the disease onset, mean HbA1c since the onset, and lipid profile on vascular density was tested. Fifty-three patients (median age 15.5, IQR 12.4-19.4 years; 57% females) with type 1 diabetes and 48 controls were enrolled. The median (IQR) HbA1c was 7.6% (60 mmol/mol) (6.9-8.1%, 52-65 mmol/mol), and the median (IQR) duration of disease was 6.0 (3.3-10.3) years. Mean vessel density measured with OCTA was lower in patients compared to controls with the temporal sector showing the highest difference both in the SCP (0.55 vs. 0.57, p<0.001) and the DCP (0.63 vs. 0.65, p<0.001). None of the predictors was associated with the superficial and deep vascular densities. Only 2 patients had clinically detectable DR. Microvascular structural changes were found on OCTA in both of these patients and in one without funduscopic alterations. In conclusion, patients with type 1 diabetes without clinically detectable DR had decreased capillary density compared to controls on OCTA images. These findings may provide useful information for the screening and the management of patients with type 1 diabetes. Further studies are needed to confirm our results and their clinical relevance.

Background The reproducibility of patient setup for radiotherapy is based on various methods including external markers, X-rays with planar or computerized image acquisition, and, more recently, surface matching imaging. We analyzed the setup reproducibility of 16 patients affected by prostate cancer who underwent conformal radiotherapy with curative intent by using a surface image registration system. Methods We analyzed the setup reproducibility of 16 patients affected by prostate cancer candidates for conformal radiotherapy by using a surface image registration system. At the initial setup, EPID images were compared with DRRs and a reference 3D surface image was obtained by the AlignRT system (Vision RT, London, UK). Surface images were acquired prior to every subsequent setup procedure. EPID acquisition was repeated when errors > 5 mm were reported. Results The mean random and systematic errors were 1.2 ± 2.3 mm and 0.3 ± 3.0 mm along the X axis, 0.0 ± 1.4 mm and 0.5 ± 2.0 mm along the Y axis, and 2.0 ± 1.8 mm and -0.7 ± 2.4 mm along the Z axis respectively. The positioning error detected by AlignRT along the 3 axes X, Y, and Z exceeded the value of 5 mm in 14.1%, 2.0%, and 5.1% measurements and the value of 3 mm in 36.9%, 13.6% and 27.8% measurements, respectively. Correlation factors calculated by linear regression between the errors measured by AlignRT and EPID ranged from 0.77 to 0.92 with a mean of 0.85 and SD of 0.13. The setup measurements by surface imaging are highly reproducible and correlate with the setup errors detected by EPID. Conclusion Surface image registration system appears to be a simple, fast, non-invasive, and reproducible method to analyze the set-up alignment in 3DCRT of prostate cancer patients.
