Studies have shown a reduced quality of life (QoL) in adults with EPP, however, data on children with the disease are lacking. Since treatment for EPP is currently not registered for children, knowledge about their QoL is of crucial importance. In this prospective, case–control study, we included children from the Netherlands and Belgium diagnosed with EPP and matched to healthy controls. Previously collected EPP quality of life (EPP-QoL) data from matched adults with EPP were used. QoL scores, utilizing the Pediatric Quality of Life Inventory (PedsQL) and the disease-specific EPP-QoL, were collected. Scores range from 0 to 100, with higher scores indicating a higher QoL. Non-parametric tests were used to compare groups. A total of 15 cases, 13 matched healthy control children, and 15 matched adults with EPP were included. Children with EPP exhibited lower median scores in the PedsQL in both physical (cases: 87.5 (interquartile range [IQR] 77.7–96.1), controls: 99.2 [IQR 94.9–100.0], <i>p</i> = 0.03) and social (cases: 77.5 [IQR 69.4–86.3], controls: 97.5 [IQR 78.8–100.0], <i>p</i> = 0.04) domains compared to healthy children, although these differences were not statistically significant after correcting for multiple testing. The overall median EPP-QoL score for children was similar to adults with EPP (children: 44.4 [IQR 25.0–54.2], adults: 45.8 [IQR 25.7–68.1], <i>p</i> = 0.68). However, within the EPP-QoL subdomain on QoL, children were found to have significantly lower median scores (children: 16.7 [IQR 0.0–33.3], adults: 33.3 [IQR 33.3–62.5], <i>p</i> &lt; 0.01). In conclusion, children with EPP experience a reduced QoL compared to both healthy children and adults with EPP.

On the other hand, the Antoni B area of some schwannomas was reported to be positive for CD34. Therefore, the definition of a hybrid tumor has not been clear. The objective of this study was to determine whether only CD34 positive findings in schwannomas could be used to define a hybrid tumor. In the analysis of our patient with schwannomatosis caused by a novel <i>LZTR1</i> germline mutation, part of the tumor had CD34 positive hypocellular regions. These regions contained no thin, wavy, nuclei, indicating an Antoni B area. Laser microdissection was used to investigate the genetic background and differences in molecular mechanisms between CD34 positive and CD34 negative regions. All mutations identified in CD34 positive regions were also found in CD34 negative regions. Our data could not clear the genetic background of Antoni B which was CD34 positive area. We then reviewed the pathologies of 66 sporadic schwannomas. Histopathological examinations of all schwannomas revealed the absence of thin, wavy, nuclei and wavy collagen bands, and no hybrid tumors were found in any of the cases. Ten of 66 patients were randomly selected for CD34 immunostaining and positivity was found in all cases.

However, it is required for the comparative study of efficacy and safety between biosimilar and originator because all biosimilars may not be identical to the originator. In this study, we compared the treatment effects and safety of biosimilar (Truxima) and originator (MabThera) rituximab in patients with pemphigus. A final cohort of 52 patients in the MabThera group and 72 patients in the Truxima group was enrolled. Except for the intravenous immunoglobulin administration rate, there were no differences in baseline characteristics between the two groups, and for the purpose of comparing efficacy, investigations into time to complete remission, total steroid intake to complete remission, and total steroid intake for 6 months following rituximab treatment revealed no significant differences between the two groups. Truxima can be considered a relatively affordable alternative treatment option for pemphigus, offering cost-effectiveness to patients who are indicated for the treatment with MabThera.</p>","PeriodicalId":54848,"journal":{"name":"Journal of Dermatology","volume":"51 8","pages":"1104-1107"},"PeriodicalIF":2.9,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1346-8138.17329","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141319431","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}
