Paediatric rheumatology: Juvenile idiopathic arthritis--are biologic agents effective for pain?
Nature Reviews. Rheumatology
|July 4, 2013
Insights
Biologic medications effectively treat juvenile idiopathic arthritis. However, some children on anti-TNF agents experience persistent pain even with controlled disease, necessitating pain monitoring during treatment.
Area of Science:
- Pediatric Rheumatology
- Immunology
- Pharmacology
Background:
- Juvenile idiopathic arthritis (JIA) is a chronic autoimmune condition affecting children.
- Biologic medications, particularly anti-tumor necrosis factor (anti-TNF) agents, are cornerstone therapies for moderate to severe JIA.
- While effective in controlling inflammation, the impact on patient-reported pain requires further investigation.
Discussion:
- A recent study identified a subset of JIA patients on anti-TNF therapy experiencing persistent pain.
- This pain persisted despite objective measures indicating good control of the underlying autoimmune disease.
- This disconnect suggests that pain in JIA may have multifactorial origins beyond active inflammation.
Key Insights:
- Persistent pain can occur in JIA patients treated with anti-TNF biologics, irrespective of disease activity.
- Current disease control metrics may not fully capture the patient's experience of pain.
- Close monitoring of pain symptoms is crucial for comprehensive management of JIA.
Outlook:
- Future research should explore the mechanisms behind persistent pain in treated JIA patients.
- Investigating non-inflammatory pain pathways and psychological factors is warranted.
- Developing targeted pain management strategies alongside disease-modifying antirheumatic drugs (DMARDs) is essential for improving quality of life in JIA.
Abstract:
Biologic medications are highly efficacious in juvenile idiopathic arthritis. However, a recent study found that a subgroup of children treated with anti-TNF agents had persistent pain despite good disease control. This finding highlights the importance of monitoring pain symptoms during treatment with modern DMARDs.

01:24Drugs 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 (Humira),...
01:29Inflammatory 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.

01:29Drugs 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 Disease...
01:25Analgesia and Pain Management
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...
01:20The JAK-STAT Signaling Pathway
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...
01:21Drugs 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 (COX-2),...
