Insights
Thalidomide shows promise for treating pediatric inflammatory bowel disease (IBD) refractory to other treatments, improving remission rates. However, peripheral neuropathy is a key risk requiring careful monitoring in children and adolescents.
Area of Science:
- Pediatric Gastroenterology
- Pharmacology
- Immunology
Background:
- Thalidomide is an off-label treatment for inflammatory bowel disease (IBD).
- Its use in pediatric populations is not well-established, with contraindications for children due to unknown safety and efficacy.
- This review focuses on thalidomide's role in pediatric IBD management.
Purpose of the Study:
- To review the efficacy and safety of thalidomide for treating IBD in children and adolescents.
- To synthesize current evidence on thalidomide's effectiveness in pediatric IBD patients.
Main Methods:
- A comprehensive literature search was conducted in databases including PubMed, Embase, and Cochrane Library.
- Studies included systematic reviews, meta-analyses, randomized controlled trials (RCTs), cohort studies, case-control studies, and case series up to June 2019.
- Inclusion criteria focused on thalidomide use for IBD in pediatric populations.
Main Results:
- Seven studies (2 RCTs, 5 case series) involving 134 pediatric patients (32 with ulcerative colitis, 102 with Crohn's disease) were analyzed.
- Thalidomide demonstrated clinical remission rates of 44%-100% and steroid tapering rates of 50%-100% in refractory pediatric IBD.
- Peripheral neuropathy was the most frequent serious adverse event, appearing dose-dependent.
Conclusions:
- Thalidomide can effectively induce and maintain remission in children and adolescents with refractory IBD.
- Peripheral neuropathy is a significant adverse reaction that necessitates monitoring and preventative strategies.
- Informed consent and thorough communication with parents are crucial before initiating thalidomide therapy in pediatric patients.
What Is Known And Objective:
Thalidomide is used off-label for the treatment of inflammatory bowel disease (IBD) and not as a first-line treatment option. The instructions clearly state that thalidomide is contraindicated in children because its safety and effectiveness in children are unknown. In this article, we review the efficacy and safety of thalidomide as a treatment for IBD in children and adolescents.
Methods:
We searched PubMed, Embase, the Cochrane Library, CNKI, WanFang Data, CBM database [from the date of database establishment to June 2019] and clinical trials [systematic review and meta-analysis, randomized controlled trials (RCTs), cohort studies, case-control studies and case series studies] for studies concerning the use of thalidomide as a treatment for IBD in children and adolescents.
Results And Discussion:
Seven studies (two RCTs and five case series), which included 134 children and adolescents (32 with ulcerative colitis, 102 with Crohn's disease), met the inclusion criteria. The included studies showed that the clinical remission rate of thalidomide was 44%-100% and the steroid tapering rate was 50%-100% in children and adolescents with refractory IBD. Peripheral neuropathy was the most common major adverse reaction, and it appeared to be cumulative dose-dependent.
What Is New And Conclusion:
Thalidomide as a treatment for refractory IBD in children and adolescents can improve clinical remission and achieve longer-term maintenance of remission. Peripheral neuropathy is the main adverse drug reaction, and it can be monitored and prevented. It is necessary to fully communicate with parents and obtain informed consent before using this drug.
