Insights

Growth disorders in children with chronic inflammatory diseases are linked to inflammatory cytokines. New biologic drugs targeting these cytokines show promise for improving growth in pediatric patients.

Area of Science:

  • Pediatric Endocrinology
  • Immunology
  • Rheumatology

Background:

  • Growth disorders are prevalent in children with chronic inflammatory diseases like inflammatory bowel disease and juvenile idiopathic arthritis.
  • Factors contributing to growth failure include poor nutrition, immobilization, medications, and disease severity.

Purpose of the Study:

  • To provide an updated review on growth disorders in pediatric chronic inflammatory diseases.
  • To emphasize the role of inflammatory cytokines in mediating growth impairment.

Main Methods:

  • Review of current scientific literature on growth disorders and inflammatory cytokines.
  • Analysis of recent studies on the impact of inflammatory cytokines on growth velocity and body composition.

Main Results:

  • Inflammatory cytokines, such as tumor necrosis factor-α and interleukin-6, are key mediators of growth failure.
  • Recent studies confirm a direct association between elevated cytokine levels and reduced growth.
  • New biologic therapies demonstrate efficacy in controlling disease activity and improving growth outcomes.

Conclusions:

  • Growth retardation is a significant challenge in pediatric chronic inflammatory diseases, with proinflammatory cytokines playing a central role.
  • Targeting inflammatory cytokines with novel therapies shows promise for enhancing growth.
  • Further research is needed to define cytokine profiles and optimize treatment strategies for affected children.

Role of Hematopoietic Growth Factors01:28

Role of Hematopoietic Growth Factors

Hematopoietic growth factors are molecules that regulate the differentiation rate of hematopoietic stem cells (HSCs). Erythropoietin (EPO), primarily produced by the kidneys, plays a crucial role in erythrocyte production. When oxygen levels in the blood are low, EPO is released into the bloodstream, reaching the bone marrow, where it stimulates HSCs to differentiate and mature into erythrocytes, which are vital for oxygen transport.
Thrombopoietin (TPO), mainly released by the liver,...
Inflammatory Bowel Disease III: Crohn's Disease01:25

Inflammatory Bowel Disease III: Crohn's Disease

Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...
Inflammatory Response01:28

Inflammatory Response

An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...
Nature and Nurture01:10

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience, such as differences...
TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors are of three kinds RI, RII, and RIII. The RI...
Chronic Inflammation: Introduction01:12

Chronic Inflammation: Introduction

Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
