Introduction

Progranulin is a novel growth factor that has several physiological and pathological roles such as cell growth, tumourigenesis, embryogenesis, wound healing, and inflammation.

Aim

To compare the pre-treatment and post-treatment serum levels of the angiogenic factor vascular endothelial growth factor (VEGF), pro-inflammatory cytokine tumor necrosis factor  (TNF-), and progranulin in peptic ulcer (PU) patients with a healthy control group.

Material and methods

Serum VEGF, TNF-, and progranulin levels were studied with ELISA in 42 PU patients (antral ulcer (AU): 22, duodenal ulcer (DU): 20) and 15 healthy controls.

Results

The serum progranulin levels before treatment were 4237.35 ±1091.30 pg/ml in the patients with AU, 4682.64 ±1501.46 pg/ml in the patients with DU, 3055.66 ±626.88 pg/ml in the control group, and 4460 ±1315 pg/ml in the ulcer (AU and DU) group. The serum progranulin levels were 3607.7 ±869.4 pg/ml in the AU group, 4286.5 ±1208.78 pg/ml in the DU group, and 3947.1 ±1094.64 pg/ml in the ulcer group after the treatment. When comparing pre-treatment serum progranulin levels of the AU group, DU group, and ulcer group with the control group there were statistically significant differences (p < 0.001, p < 0.0001, p < 0.0001, respectively).

Conclusions

The disappearance of the difference in terms of post-treatment serum levels of progranulin between the AU group and the control group suggests that serum levels of progranulin can be used as a biomarker of gastric ulcer healing.
