Objective To investigate the clinical significance of the level of serum amylase and serum IgA and total IgE in henoch-schonlein purpura patients with gastrointestinal involvement (also known as "Henoch purpura ").
Methods Levels of serum amylase and serum IgA and total IgE in henoch-schonlein purpura patients with or without abdominal pain or patients with acute abdominal pain were compared.
Results The average level (180.3 ± 15.8 IU) of serum amylase of Henoch purpura patients was significantly higher than HSP patients without abdominal pain and acute abdominal pain patients (F=32.214, P=0.009); Ratio of cases of increased level of serum IgA in henoch purpura abdomen patients was 44.2%, and there was no significant difference with HSP patients without abdominal pain. But ratio of two groups was respectively higher than the acute abdominal pain patients group (χ2=13.73, P=0.001); Ratio of cases of increased level of serum IgE in Henoch purpura abdomen patients accounted for 40.4%, but there was no significant difference among the three group (χ2=1.80，P=0.41).
Conclusion Levels of serum amylase increase and serum IgA increase conduce to diagnose HSP patients with the onset of abdominal pain, and serum total IgE has little significance.
