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.

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids

Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

Inflammatory Bowel Disease IV: Pharmacological Management

Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.

Drugs for Treatment of Ulcerative Colitis in IBD

Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide...

Drugs for Treatment of Diarrhea-Predominant IBS

Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...
