A study was completed to discover the understanding of hormonal regulation of gastric lipase secretion in children and adolescents, as this is still very limited.
Tomasik et al. (2013) <ref name="gastritis" /> investigated the hormonal regulation of human gastric lipase secretion in children and adolescents with gastritis -- the most common gastric condition, in which inflammation occurs in the lining of the stomach -- as there is little existing literature regarding this subject. HGL activity was compared across three groups: one experimental group consisting of adolescents diagnosed with Helicobacter pylori gastritis (n = 10), another experimental group consisting of adolescents with a non-H. pylori induced form of gastritis (n = 10), and one control group of healthy adolescents (n = 14). HGL activity, in addition to plasma concentrations of glucagon-like peptide-1, cholecystokinin, and glucose-dependent insulinotropic peptide, were observed through analysis of gastric juice samples that had been collected via endoscopic measurements from each patient.


The activity of human gastric lipase was compared among two experimental groups and one control group.  The control group included 14 healthy adolescents.  The experimental groups were one group of 10 patients diagnosed with ''Helicobacter pylori'' gastritis, and another group of patients exposed to other pathogens besides ''Helicobacter pylori'' to cause gastritis.  The activity of human gastric lipase was observed through endoscopic measurements within the collected gastric juice from each patient.  The plasma concentrations of glucagon-like peptide-1, cholecystokinin, and glucose-dependent insulinotropic peptide were determined in all patients as well. 
Patients whose superficial gastritis was induced by pathogens other than H. pylori exhibited lower levels of HGL activity compared to both healthy adolescents (p < .005) and those who were diagnosed with H. pylori gastritis (p < .005). Mean plasma concentrations of glucose-dependent insulinotropic peptide were lower in healthy patients (p < 0.005) than in those with non-H. pylori gastritis (p < .003) and those with H. pylori gastritis (p < 0.01).  Regulation of HGL secretion by glucagon-like peptide-1 and cholecystokinin was therefore found to be altered in adolescents with gastritis. In addition, glucose-dependent insulinotropic peptide was found to be a powerful activator of human gastric lipase activity in all experimental and control groups <ref name="gastritis" />.
 
This study suggested that the activity of human gastric lipase activity was changed in patients that were diagnosed with superficial gastritis induced by pathogens other than ''Helicobacter pylori''.  The level of activity of human gastric lipase was significantly lower in patients with superficial gastritis than in patients that were healthy (p<0.005) and were diagnosed with ''Helicobacter pylori'' gastritis (p<0.005). The mean levels of glucose-dependent insulinotropic peptide plasma concentrations were lower for patients in the control group (p<0.005) than in non-''Helicobacter pylori'' gastritis and ''Helicobacter pylori'' gastritis patients (p<0.01).  The regulation of human gastric lipase secretion by glucagon-like peptide-1 and cholecystokinin was found to be altered in those whom had gastritis. Glucose-dependent insulinotropic peptide in both healthy and gastritis-diagnosed patients was found to be a powerful controller of human gastric lipase activity <ref name="gastritis" />.
