Abstract

Background: Psoriasis is a prevalent inflammatory skin condition that can be recognized by silvery-white scales on plaques and erythematous papules, despite the fact that psoriasis appears to have multiple causes. Helicobacter pylori (H. pylori) has been investigated recently as a potential infectious etiological component.

Aims: The objective of the study was to evaluate the prevalence of H. pylori infection in psoriatic patients compared to that of healthy controls and determine whether the degree of psoriasis and H. pylori infection were related.

Patients and methods: The dermatology, venerology, and andrology department at South Valley University Outpatient Clinic carried out this cross-sectional study. Psoriatic patients of both sexes and ages were included. In addition to the control group, H. Pylori antigen was measured from psoriatic and control groups by using H. pylori stool antigen-enzyme linked immunosorbent assay (HpSA-ELISA), a test for H. pylori stool antigen. More than 20 ng/mL of antigen proved positive, or less than 15 ng/mL proved negative.

Results: There was a significant difference between psoriatic patients and control regarding H. pylori infection (p = 0.046): (30.66%) positive in controls, (45.33%) positive in psoriatic patients. Both groups were matched for age (p = 0.908), that is, the mean age of psoriatic patients was 37.44 ± 15.79 years, and the control group was 37.15 ± 15.15 years. Twenty-five psoriatic patients in each group: mild, moderate, and severe psoriasis according to the Psoriasis Area Severity Index (PASI) score. No significant correlation between H. pylori infection and PASI, age, or duration of illness in psoriatic patients.

Conclusions: Patients with psoriasis had greater rates of H. pylori infection but didn't affect the severity of psoriasis.

Keywords: Helicobacter pylori; PASI score; psoriasis.
