Insights

Serum prohepcidin (SP) is elevated in children with solid tumors (ST) and inflammatory bowel disease (IBD), potentially indicating inflammation and leading to anemia. SP levels are lower in iron deficiency anemia (IDA).

Area of Science:

  • Pediatric Hematology
  • Oncology
  • Gastroenterology

Background:

  • Prohepcidin regulates iron metabolism.
  • Limited research exists on prohepcidin's role in pediatric solid tumors (ST), inflammatory bowel disease (IBD), and iron deficiency anemia (IDA).

Purpose of the Study:

  • To investigate serum prohepcidin levels in children with ST, IBD, and IDA compared to healthy controls.
  • To explore correlations between prohepcidin and markers of inflammation and iron status in these pediatric conditions.

Main Methods:

  • Serum prohepcidin (SP), soluble transferrin receptor (sTfR), serum ferritin (SF), serum iron (SI), transferrin saturation (TS), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) were measured.
  • Levels were compared across groups: ST (n=16), IBD (n=15), IDA (n=14), and controls (n=18).

Main Results:

  • Mean SP was significantly higher in children with ST and IBD compared to those with IDA and controls.
  • SP showed significant correlations with SF in ST and IBD, and with ESR and CRP in IBD and ST, respectively.
  • In IDA, SP was correlated with TS but not with SF or sTfR.

Conclusions:

  • Elevated SP may serve as a clinical indicator of inflammation in pediatric ST and IBD.
  • Increased SP in ST and IBD might contribute to anemia by hindering iron utilization.
  • Decreased SP levels are characteristic of IDA and correlate with transferrin saturation.

Serum Laboratory Studies, Stool Test, Breath Test

Gastrointestinal (GI) diagnostic studies are pivotal in confirming, ruling out, diagnosing, or staging various diseases, including cancers. Following diagnosis, allocating time for discussions with the patient and providing informational resources is crucial. Diagnostic assessments of the GI tract often occur in outpatient settings like endoscopy suites or GI labs. Preparation for these tests may include dietary restrictions, fasting, liquid bowel preparations, laxatives, enemas, and the...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess the...

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 Bowel Disease IV: Clinical Manifestations

Inflammatory bowel disease (IBD) encompasses two major chronic disorders—ulcerative colitis and Crohn’s disease—each characterized by relapsing episodes of gastrointestinal inflammation. Although they share certain clinical features, their patterns of involvement and manifestations differ in ways that aid diagnosis and guide management.Ulcerative ColitisUlcerative colitis is limited to the colon and rectum and involves continuous inflammation of the mucosal layer. The disease course is marked...

Inflammatory Bowel Disease II: Crohn's Disease

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
