In recent years many studies have shown a relationship between Helicobacter Pylori (HP) infection and a range of skin conditions. Based on this findings, the authors have analized a possible association between HP infection with chronic idiopathic urticaria, psoriasis,

alopecia areata, lichen planus, rosacea, atopic dermatitis and nodular prurigo. The results of this case-control study show, that although this bacteria contribute to worsening symptoms, HP infection may not be incriminated as a risk factor for developing these skin diseases. HP seroprevalence in patients with skin diseases, was higher than in control group, but the results in this study haven’t had a statistical significance. The dermatologic symptoms were more pronounced in HP infected patients than those without HP infection.

Further studies are necessary to establish the role of HP eradication in dermatologic therapy.
