Serum trace elements profile in the pediatric inflammatory bowel disease progress evaluation.

INTRODUCTION

Inflammatory bowel disease (IBD), a chronic inflammatory disorder of gastrointestinal tract, arises from complex interaction between genetics, environment, gut microbiota and mucosal immune response. Along with clinical, endoscopic and radiological evaluation various biomarkers are needed as an additional diagnostic tool, as well as to predict disease course and therapeutic outcomes.

AIM

The aim of this study was to evaluate clinical value of essential trace elements (ETEs) serum concentration profile in the assessment of pediatric IBD diseases development.

MATERIALS AND METHODS

Concentration of five ETEs: iron (Fe), zinc (Zn), copper (Cu), manganese (Mn) and selenium (Se) in serum of 41 children with newly diagnosed IBD (27 CD and 14 UC) and 20 healthy controls were determined by inductively coupled plasma mass spectrometry (ICP-MS) and atomic fluorescence spectrometry (AFS) at the moment of diagnosis and after one year of treatment.

RESULTS

The obtained results revealed significant differences in serum concentration profile of studied ETEs' for IBD pediatric patients and healthy controls. Decrease of iron, zinc and selenium and increase of copper and manganese serum concentration were observed in IBD patients at the time of diagnosis. The changes were reversible and after one year of treatment the studied ETEs serum concentration profile resembled much more that observed for healthy controls. Correlations between studied ETEs levels within cases (IBD, CD, UC) were also found to be different from those in healthy controls (HC).

CONCLUSION

Although much more studies are required on the subject our results demonstrate a clinical value of ETEs serum concentration profile in pediatric IBD patients regarding disease development.
