Relationship between Lichen Planus and Helicobacter pylori Infection

Area of Science:

• Dermatology
• Gastroenterology
• Microbiology

Background:

• Lichen planus (LP) is a common chronic inflammatory condition affecting skin and mucous membranes.
• Helicobacter pylori (H. pylori) infection has been recently investigated as a potential contributing factor in LP.
• Understanding the etiology of LP is crucial for effective management and treatment strategies.

Purpose of the Study:

• To evaluate the potential association between oral and skin lichen planus (LP) and Helicobacter pylori (H. pylori) infection.
• To determine if H. pylori infection is an independent risk factor for developing LP.
• To contribute to the ongoing research on the multifactorial causes of LP.

Main Methods:

• A case-control study involving 30 patients with oral LP, 30 with skin LP, and 30 healthy controls.
• Helicobacter pylori infection was assessed using the urea breathing test (UBT) in all participants.
• Statistical analysis included descriptive statistics and the chi-square test to compare H. pylori prevalence.

Main Results:

• The prevalence of positive urea breathing tests (UBT) was 80% in the oral LP group, 73.3% in the skin LP group, and 66.7% in the control group.
• No statistically significant differences were observed in the rates of H. pylori infection among the three groups (P = 0.50).
• The findings indicate a similar prevalence of H. pylori across LP patients and healthy individuals.

Conclusions:

• This study found no significant association between lichen planus (LP) and Helicobacter pylori (H. pylori) infection.
• The results suggest that H. pylori infection is unlikely to be a major etiologic factor in the development of LP.
• Further research may be needed to explore other potential triggers or contributing factors for LP.
