ACTA ENDOCRINOLOGICA (BUC)

Background. Plasma level of ghrelin is possibly reduced in Helicobacter pylori infection and may account for the resultant failure to thrive. Objective. To investigate relationships between Helicobacter pylori infection, and plasma level of ghrelin, anthropometric measurements, appetite, educational and economical status of parents. Methods. Ninety-four children were screened for Helicobacter pylori infection with C-14 urea breath test. Anthropometric measurements were performed in Helicobacter pylori (+) and (-) groups. Plasma ghrelin was measured. Parents were asked to fill out the questionnaire prepared by the researcher on the number of family members, parents’ level of education, monthly income and children’s status for appetite. Results. Plasma ghrelin was lower in Helicobacter pylori (+) group (20.00 ± 22.10 ng/mL), compared to Helicobacter pylori (-) group (79.72 ± 78.13 ng/mL). The percentiles of measurements for height, weight and body mass index were higher in Helicobacter pylori (-) group. Results of C-14 urea breath test were negatively correlated with height, weight and body mass index; however, no correlation was detected between the results of C-14 urea breath test, and plasma ghrelin, number of family members, levels of parents’ education and income. A negative correlation was observed between the results of C-14 urea breath test and appetite. Conclusions. Helicobacter pylori infection is considered to play a restricting role in growth potential by decreasing ghrelin level in children. Moreover, the existence of a negative correlation between the results of C-14 UBT, and weight, height and body mass index suggests a possible link between Helicobacter pylori infection and poor growth.
