Influence of hippophae rhamnoides on two appetite factors, gastric emptying and metabolic parameters, in children with functional dyspepsia

Our aim was to explore in children with functional dyspepsia the effect of hippophae rhamnoides on the levels of plasma appetite factors and on their gastrointestinal motility. A hundred and twenty children with functional dyspepsia were randomly divided into three groups: Group I (treated with hippophae rhamnoides), Group II (treated with domperidone), and Group ill (treated with hippophae rhamnoides plus domperidone). The treatment lasted for eight weeks. The levels of plasma leptin (LP) and neuropeptide Y (NPY) were measured before and after treatment. All patients underwent a gastric emptying (GE) test by ultrasound (US) to measure the rate of postprandial gastric antrum residual, at 30min, 60min, 90min and 120min. The average value of subcutaneous fat, body fat percentage, upper arm girth and body mass index (BMI) were also measured. To compare the US with the radionuclide GE test 14 healthy adults volunteers were tested by both GE techniques. We found that the levels of LP and NPY in plasma were markedly higher after treatment in Groups I and III than in Group II. The postprandial gastric antrum remains at 60min, 90min and 120min in Groups land III fell greatly and the thickness of skin fold (SF), body fat percentage and arm girth increased (P<0.05). The GE half emptying time of a mixed liquid-solid food measured by B US and by the radionuclide technique in the same individuals was similar (P>0.05). In conclusion, in children's functional dyspepsia, our study showed that hippophae rhamnoides increases the levels of appetite factors, leptin and neuropeptide Y, increases gastric emptying and gastrointestinal digestive function, children's growth and development.
