Xacrel, the Iranian-made OCR biosimilar, requires further investigation for its effectiveness in MS treatment.

Long-term satisfaction was sustained in both groups (100% of r-IPG carriers and 75.7% of nr-IPGs, <i>p</i> = 0.001). In r-IPGs, 97.7% recharged the battery easily, and recharging time did not impact everyday life. The percentage of malfunctioning problems (32.6%) in the r-IPG group was in line with previous observations on short-term follow-ups. The size of the IPG was considered too big for 16.2% and 4.2% for nr-IPGs and r-IPGs (<i>p</i> = 0.086), and concerns of interventions for IPG replacements were still present in the nr-IPG group (48.6%). The total amount of days of hospitalization (19.6 ± 9.9 vs. 9.3 ± 4.8, <i>p</i> < 0.001) and the number of complications after the first implant (13 vs. 5, <i>p</i> < 0.05) and during subsequent admissions for IPG substitutions (4 vs. 0, <i>p</i> < 0.05) were higher for the nr-IPGs.</p><p><b>Conclusions:</b> The overall level of long-term satisfaction with IPGs is consistent over time regardless of type. R-IPGs reported no discomfort with recharging even in the long-term evaluation. IPG replacement surgeries and sizes are still a concern, especially for the nr-IPG carriers, but did not affect a high level of sustained satisfaction. Resource burden remains higher for nr-IPGs even in the long term.</p>","PeriodicalId":6939,"journal":{"name":"Acta Neurologica Scandinavica","volume":"2025 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/ane/6097313","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144681317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
