Background: H.pylori colonized gastric mucosal
epithelium will virtually develop gastritis and had the
capacity to persist for decades. Pathogenesis is
dependent upon strain, virulence host genetic
susceptibility, and environmental cofactors. Leptin is
a member of the class 1 cytokine family so altered
leptin production during ifnect and inflammation that
leptin part of the cytokine cascade ,which
orchestrates the defense mechanism.
Objective: Examin the effect of H.pylori infection
on serum leptin level.
Methods: One hundred and thirty(130) Patients
attending the Endoscopic Unit at "Gastroenterology
and Hepatology Teaching Hospital/ Baghdad Medical
City"were included in this study with ages range
from 18 years to 65 years are the source of specimens
to undergo oesophageal gastroduodenoscopy (OGD)
compared with twenty healthy control the study
began from April 2009 to the end of March 2010
were eligible for this study.Tow types of samples
were taken, biopsy for rapid urease test and
histopathological examination to detect H.pylori and
blood sample for estimation of serum leptin by
ELISA test.
Results: The results show significant increase in
serum leptin concentration(P<0.001)in gastritis
patients caused by H.pylori compared with patients
control and healthy control.
Conclusion: Increase of serum leptin concentration
explained the role of leptin in the immune response to
H.pylori infection that leptin consider as member of
cytokine
