Relationship between Helicobacter pylori infection and vitiligo: a prospective study

Area of Science:

• Dermatology
• Gastroenterology
• Microbiology

Background:

• Helicobacter pylori (H. pylori) is a bacterium affecting multiple organ systems, including the skin.
• Previous studies linked H. pylori to skin conditions like psoriasis and lupus erythematosus.

Purpose of the Study:

• To investigate the potential association between H. pylori infection and vitiligo.
• To compare H. pylori prevalence in vitiligo patients versus a control group.

Main Methods:

• A prospective study involving 133 patients (68 with vitiligo, 65 with telogen effluvium).
• H. pylori infection was detected using urea breath test (UBT), and serum IgG and CagA antibodies were measured.
• Patients were assessed for dyspepsia and vitiligo disease activity.

Main Results:

• Vitiligo patients showed significantly higher rates of H. pylori positivity, CagA, and IgG compared to the telogen effluvium group.
• Dyspepsia was also more prevalent in the vitiligo group.
• No correlation was found between H. pylori status and vitiligo disease activity or subtype.

Conclusions:

• The study suggests a potential link between H. pylori infection and vitiligo.
• Further research is required to explore the role of H. pylori eradication in vitiligo management and its pathogenic mechanisms.
