ABSTRACT
Nearly 10% of children and adolescents in the United States experience migraine. Pharmacologic treatment of migraine in adolescents is limited due to only few US Food and Drug Administration (FDA)-approved medications, limited efficacy, or lack of tolerability. Remote Electrical Neuromodulation (REN) is a nonpharmacologic abortive treatment for migraine, cleared by the FDA for patients aged 12 years and above. This study evaluated real-world efficacy of REN in adolescents aged 12 to 17 years. Real-world data were collected from patients aged 12 to 17 years treated with the REN device (Nerivio) from January 1, 2021, to May 31, 2022. Study's end points included consistent efficacy two hours after treatment, use of REN as a standalone versus as an adjunct therapy, treatment intensity, and safety. Of 1629 adolescents included in the study, consistent response in at least 50% of treatments at two hours posttreatment was achieved by 60.3% of patients for pain relief, 26.3% for pain freedom, 66.3% for functional disability relief, and 41.2% for functional disability freedom. Of 2365 treatments in which medication usage was reported, REN was used as standalone therapy in 64.4% of the treatments, REN was combined with over-the-counter medications in 18.6%, and it was combined with prescription medications in 17%. Mean treatment intensity from 13,716 treatments was 28.5% (±13.6%) of the max stimulator output. Only three device-related adverse events were reported, all minor. This real-world analysis demonstrates the persistent efficacy of REN for abortive treatment of migraine in adolescents, extending findings of prior clinical trials in adolescents and real-world studies in adults.

Introduction: Migraine is a chronic neurological disease that is the primary cause of years lived with disability in people under the age of 50. Remote electrical neuromodulation (REN) is a novel drug-free acute treatment of migraine, that is FDA cleared for episodic and chronic migraine. As a prescribed digital therapeutic, REN enables large-scale post-marketing research, thus providing real-world information on the use of the intervention in a wide range of populations, environments, and situations. Methods: The REN device (®Nerivio) includes a secured, personal migraine diary, which patients can use to record their symptoms before treatment and 2 h post-treatment. Real-world data on REN treatments were collected via the app from patients across the United States who used Nerivio between October 1st, 2019, and May 24th, 2021. Data analysis focused on four metrics: 1. Per-treatment patterns of REN use as a standalone treatment vs. in combination with medications. 2. Per-user intra-individual efficacy across multiple treatments. 3. Distribution of treatment intensity among users (the electroceutical equivalent to treatment dose). 4. Prevalence and severity of adverse events. Results: 1. Out of 23,151 treatments, in 66.5% of treatments REN was used as a standalone treatment, in 12.9% it was followed by over-the-counter medications, and in 20.6% followed by prescription medications. 2. Out of 2,514 patients, response in at least 50% of treatments was achieved in 66.5% of cases for pain relief, and in 22.6% for pain freedom. 3. Out of 117,583 treatments, in 80% of cases intensity levels were between 18 and 55% of the stimulator's range. The mean intensity was 34.3% of the stimulator's output (±16.6%). 4. Out of 12,368 users (121,947 treatments), there were 59 users (0.48%) who reported device related adverse events, 56 (0.45%) of which were mild, three (0.03%) were moderate, and none were severe. Conclusions: The current analysis of real-world clinical data indicates that REN provides an efficacious, stable, and safe treatment option for acute treatment of migraine in real-world settings, both as a standalone replacement of pharmaceuticals, as well as an adjunct to medications.
ABSTRACT
BACKGROUND: A family history of inflammatory bowel disease (IBD) is present in some ulcerative colitis (UC) patients. We aimed to investigate the familial occurrence of UC and its impact on disease severity. METHODS: A structured questionnaire was distributed to patients with UC. Parameters pertaining to disease severity were compared for patients with or without positive family history of IBD. RESULTS: The study group consisted of 168 UC patients with a total of 952 first degree relatives. Positive family history for IBD in a first degree relative was reported in 24 patients (14%). Six of the 336 parents (1.8%) had IBD (all with UC). There were 13 siblings with IBD (4 CD, 9 UC) out of 249 (5.4%). Seven of 376 (1.9%) offsprings had IBD (4 CD, 3 UC). Familial patients were more commonly females and have reported significantly more disease exacerbations than the sporadic group (17.7±15 versus 6.8±11, respectively, p=0.006). On multivariate analysis, familial disease was significantly and independently associated with both female sex (OR 4.1, 95% CI 1.1-14.9, p=0.04) and more exacerbations per year (annual OR 1.05, 95% CI 1.01-1.1, p=0.02). However, similar proportions of sporadic and familial patients wherever hospitalized, underwent colectomy or were treated by immune-suppressors. CONCLUSIONS: Familial occurrence of UC is not uncommon among Jewish patients in Israel. The familial-genetic component may preferentially influence disease occurrence among females, and is possibly associated with more disease flares although other parameters of disease severity do not seem to be impacted.
