Abstract Prostanoid content prostaglandin E2 (PGE2) and thromboxane B2 (TxB2) and endocrine cells population were evaluated in jejunal biopsies from celiac children; findings were compared to active celiac patients on a challenge diet. Patients were divided as follows: Group A: 14 children with active untreated celiac disease; Group B: 7 celiac children on gluten challenge who had received diet therapy for the past 2 years; Group C: 8 normal control children. Jejunal biopsies were used for endocrine cell population measurement by immunocytochemistry, using a specific marker (chromogranin), and for prostanoid radioimmunological evaluation. The quantitative assessment of the endocrine cell population in Groups A and B revealed a significantly higher number of endocrine cells (20 +/- 11.5; 18.4 +/- 9.8 n. cell/visual field respectively) compared to Group C (8.44 +/- 2.3 n. cell/visual field) (p less than 0.05). In the jejunal extract the PGE2 content (341.8 +/- 82.3) ng/g) for Group A biopsies was significantly higher than that of Group C biopsies (93 +/- 23 ng/g) (p less than 0.05. The PGE2 content (69.4 +/- +13.2 ng/g) for Group B did not show any statistically significant change. In contrast, TxB2 content in jejunal biopsies from all three groups was not significantly different.

Abstract

Abstract Prostanoid content prostaglandin E2 (PGE2) and thromboxane B2 (TxB2) and endocrine cells population were evaluated in jejunal biopsies from celiac children; findings were compared to active celiac patients on a challenge diet. Patients were divided as follows: Group A: 14 children with active untreated celiac disease; Group B: 7 celiac children on gluten challenge who had received diet therapy for the past 2 years; Group C: 8 normal control children. Jejunal biopsies were used for endocrine cell population measurement by immunocytochemistry, using a specific marker (chromogranin), and for prostanoid radioimmunological evaluation. The quantitative assessment of the endocrine cell population in Groups A and B revealed a significantly higher number of endocrine cells (20 +/- 11.5; 18.4 +/- 9.8 n. cell/visual field respectively) compared to Group C (8.44 +/- 2.3 n. cell/visual field) (p less than 0.05). In the jejunal extract the PGE2 content (341.8 +/- 82.3) ng/g) for Group A biopsies was significantly higher than that of Group C biopsies (93 +/- 23 ng/g) (p less than 0.05. The PGE2 content (69.4 +/- +13.2 ng/g) for Group B did not show any statistically significant change. In contrast, TxB2 content in jejunal biopsies from all three groups was not significantly different.
