Abstract:

Objective

To investigate the clinical characteristics of patients with concurrent gastric and colonic polyps and their relationship with different subtypes of Helicobacter pylori (Hp) infection.

Methods

Total of 300 patients who underwent gastroscopy and colonoscopy in the Department of Gastroenterology, Shanghai Shibei Hospital from October 2018 to October 2023 were enrolled. According to the results of gastrointestinal endoscopy, the patients were divided into concurrent gastric and colonic polyp group (92 cases), isolated gastric polyp group (106 cases) and isolated colonic polyp group (102 cases). The clinical data, gastrointestinal endoscopy findings, Hp infection rate and subtype distribution were compared among the three groups. The independent influencing factors for gastric polyps combined with colorectal polyps of different pathological types, as well as for Hp infection in these patients were analyzed by multivariate Logistic regression analysis. The multiplicative interaction between clinical factors and Hp infection in patients with concurrent gastric and colonic polyps were analyzed by an unconditional Logistic regression model, and additive interaction was analyzed by an interaction calculation table.

Results

Gender (χ2=7.133, P=0.028), age (F=65.696, P=0.015), body mass index (BMI) (F=27.501, P=0.036), smoking history (χ2=6.765, P=0.034), drinking history (χ2=7.797, P=0.020), Hp infection (χ2=10.460, P=0.005), fatty liver (χ2=6.031, P=0.049), diabetes mellitus (χ2=6.427, P=0.040), interleukin-6 (IL-6) (F=12.675, P=0.023) and transforming growth factor-α (TGF-α) (F=33.368, P=0.030) among the three groups were all with significant differences. Results of multivariate Logistic regression analysis showed that age (OR=2.503, 95%CI: 2.121-3.689, P=0.023), drinking history (OR=3.553, 95%CI: 2.868-4.712, P=0.009), Hp infection (OR=3.217, 95%CI: 2.614-4.386, P=0.014), fatty liver (OR=1.631, 95%CI: 1.328-2.512, P=0.036) and diabetes mellitus (OR=2.612, 95%CI: 2.181-3.711, P=0.021) were independent influencing factors for different pathological types of gastrointestinal polyps. The distribution of Hp subtypes was significantly different among the three groups (χ2=14.700, P=0.001). The infection rate of type Ⅰ Hp was significantly higher in concurrent gastric and colonic polyp group (68.52%) than that of isolated gastric polyp group (41.03%) and isolated colonic polyp group (30.95%) (χ2=6.983, P=0.008; χ2=13.359, P=0.001). Results of Logistic regression analysis revealed that age (OR=2.411, 95%CI: 1.866-3.598, P=0.012), drinking history (OR=2.315, 95%CI: 1.645-3.487, P=0.016), fatty liver (OR=2.132, 95%CI: 1.431-3.065, P=0.031) and diabetes mellitus (OR=2.268, 95%CI: 1.513-3.251, P=0.024) were all independent risk factors for Hp infection in patients with concurrent gastric and colonic polyps. Interaction analysis indicated that age (ORmultiplicative=5.136, 95%CImultiplicative: 1.358-15.842, Pmultiplicative=0.007; ORadditive=8.624, 95%CIadditive: 3.499-13.652, Padditive=0.003), drinking history (ORmultiplicative=4.954, 95%CImultiplicative: 1.006-12.834, Pmultiplicative=0.008; ORadditive=8.239, 95%CIadditive: 3.289-15.421, Padditive=0.004), fatty liver (ORmultiplicative=4.536, 95%CImultiplicative: 1.123-10.348, Pmultiplicative=0.009; ORadditive=8.892, 95%Cadditive : 1.869-17.212, Padditive=0.002), diabetes mellitus (ORmultiplicative=5.360, 95%CImultiplicative: 1.286-16.532, Pmultiplicative=0.006; ORadditive=8.627, 95%CIadditive: 1.217-15.964, Padditive=0.003) and type Ⅰ Hp infection exhibited multiplicative and additive interactions in the development of concurrent gastric and colonic polyp.

Conclusions

Age, drinking history, fatty liver and diabetes mellitus are independent influencing factors of Hp infection in patients with gastric polyp and colonic polyp, and there is a synergistic interaction between the above factors and type Ⅰ Hp infection in the occurrence of the disease. In clinical practice, colonoscopy is recommended for patients with such gastric polyp to early detect and intervene possible coexisting colonic lesions.
