More Than a Headache: Lived Experience of Migraine in Youth.

BACKGROUND: Migraine is the leading cause of disability among adolescents and young adults. We aimed to characterize the impact of migraine on the experience of children, adolescents, and caregivers. METHODS: This descriptive qualitative study recruited youth aged four to 18 years with migraine and their caregivers from the multicenter, prospective Pediatric Migraine Registry between 2020 and 2021. Participants completed semistructured interviews targeting the lived experience of migraine. A conventional content analysis approach was used to analyze data. RESULTS: Thirty enrolled dyads (n = 30 children and adolescents, n = 29 caregivers) completed 59 interviews (n = 29 child and adolescent interviews, n = 30 caregiver interviews). Children and adolescents had a median age of 15 years and experienced a median of 13.5 headache days per month. Caregivers had a median age of 44 years and predominantly identified as mothers (n = 28). We identified three themes: (1) Impact on emotional well-being: participants described how their migraine experience included feelings of isolation, depression, and irritability alongside the need for social support; (2) Impact on daily life: participants described how symptoms and unpredictability impacted their ability to perform activities of daily living; and (3) Impact on school: participants described how migraine impacted their school experience, including threatened attendance and worsened performance. CONCLUSIONS: In this cohort of youth and their caregivers, we identified salient themes to characterize the experience of migraine. Our findings underscore the urgent need for effective migraine treatments and interventions targeting co-occurring mental health conditions, peer relationships, and school support.

Beyond pain control: Outcome and treatment preferences in pediatric migraine.

OBJECTIVE: The objective of this study was to describe treatment preferences and perceived quality of existing outcome measures among children and adolescents with migraine and their caregivers. BACKGROUND: Across disciplines, there is increasing recognition of the value of direct input from stakeholders. Little empirical work has been done to determine what outcomes matter most to pediatric patients with migraine and their caregivers. METHODS: In this qualitative study, we recruited participants from the multicenter, prospective Pediatric Migraine Registry. We used stratified purposive sampling to recruit children and adolescents of varied ages and headache frequency. Patients with migraine and their caregivers completed semistructured interviews targeting treatment preferences and perceived quality of existing outcome measures. Emergent themes and subthemes were identified using conventional content analysis. RESULTS: Thirty dyads of children/adolescents and their caregivers were enrolled and completed 59 interviews (n = 29 children/adolescent interviews and n = 30 caregiver interviews). Three themes emerged. (1) Symptom relief: Looking beyond headache resolution: Participants described the value of outcomes in addition to pain relief, including a reduction in migraine intensity and improvement in non-pain symptoms. (2) Trade-offs between side effects and relief: Participants described cost-benefit analyses that can occur with headache treatment and acknowledged the impact of drug side effects on daily life and medication adherence. (3) Child-centered treatment: Participants described medication attributes salient to the pediatric context, including age-appropriate routes of administration and adequate safety data. CONCLUSIONS: Children, adolescents, and caregivers impacted by migraine value outcomes in addition to traditionally studied migraine endpoints. Participants valued decreased pain severity, even in the absence of pain resolution. Participants also prioritized the absence of side effects and key medication attributes, including fast onset and age-appropriate routes of administration. These results highlight an opportunity to design patient-centered clinical trials, develop drugs, and support product labeling that align with the outcomes valued most by children and adolescents with migraine and their caregivers.

Reduced plasmablast frequency is associated with seronegative myasthenia gravis.

BACKGROUND: The immunopathology of autoimmune seronegative myasthenia gravis (SN MG) is poorly understood. Our objective was to determine immune profiles associated with a diagnosis of SN MG. METHODS: We performed high-dimensional flow cytometry on blood samples from SN MG patients (N = 68), healthy controls (N = 46), and acetylcholine receptor antibody (AChR+) MG patients (N = 27). We compared 12 immune cell subsets in SN MG to controls using logistic modeling via a discovery-replication design. An exploratory analysis fit a multinomial model comparing AChR+ MG and controls to SN MG. RESULTS: An increase in CD19+ CD20- CD38hi plasmablast frequencies was associated with lower odds of being a SN MG case in both the discovery and replication analyses (discovery P-value = .0003, replication P-value = .0021). Interleukin (IL) -21 producing helper T cell frequencies were associated with a diagnosis of AChR+ MG (P = .004). CONCLUSIONS: Reduced plasmablast frequencies are strongly associated with a SN MG diagnosis and may be a useful diagnostic biomarker in the future.
