Abstract
MEJIA-ORTIZ, Lizeth; ROSERO-GALINDO, Carol Yovanna; CARLOSAMA-ROSERO, Yeison Harvey and CASTILLO-GIRALDO, Andrés. Estimation of the frequency of Helicobacter pylori infection in patients with potentially malignant stomach lesions of the city of Pasto- Nariño, 2016-2019. Infect. [online]. 2022, vol.26, n.1, pp.46-53. Epub Nov 13, 2021. ISSN 0123-9392. https://doi.org/10.22354/in.v26i1.993.
Aim:
To estimate the frequency of Helicobacter pylori infection in potentially malignant stomach lesions in patients of the city of Pasto- Nariño.
Materials and methods:
Retrospective study with secondary analysis of sociodemographic and histopathological information derived from pathology reports for gastric biopsies of patients from the department of Nariño, Colombia from year 2016-2019.
Results:
Patients from the city of Pasto (n=359) presented a percentage of detection for Helicobacter pylori of 35.6% and the infection was significantly higher in men than in women (p=0.037). The average age of men positive for Helicobacter pylori was 44 years and women 47 years (p<0.001). The average age of the cases of chronic atrophic gastritis in men and women was 49 and 54 years respectively (p<0.001) and for intestinal metaplasia cases, the average age was 59 years in men and 61 years in women (p<0.001).
Conclusions:
In the present study, the detection of Helicobacter pylori was higher in the male group compared to the female group (43.2% vs 31.6% respectively). The frequency of atrophic chronic gastritis and intestinal metaplasia in men was 37.9% and 23.1% respectively; in women was 35.2% and 15.1% respectively.
