ARTICLE HIGHLIGHTS
Research background
Psoriasis is a multifactorial autoimmune disease, and it has been suggested that bacterial infection can contribute to the initiation or development of this disease.
Research motivation
We performed this study to discover the association between infection with Streptococcus pyogenes (S. pyogenes) as potential factors and risk of develop to psoriasis.
Research objectives
The objective of this study was to determine the impact of S. pyogenes infection and susceptibility to psoriasis using available case-control studies.
Research methods
We used a computer-assisted comprehensive literature search to obtain relevant case-control regarding to the possible connection between S. pyogenes infection and psoriasis. Finally, the impact of infection with S. pyogenes and susceptibility to psoriasis was measured using odds ratio (OR) with 95% confidence intervals (CIs).
Research results
The rate of infection with S. pyogenes in psoriatic patients vs healthy individuals was 33.4% and 16.2%, respectively. Furthermore, there is a significant association between S. pyogenes infection and development of psoriasis (OR: 6.58; 95%CI: 3.64-11.87; P = 0.001)
Research conclusions
Infection with S. pyogenes is a risk factor for susceptibility to psoriasis.
Research perspectives
Further long-term cohort studies are needed to investigate the relationship between S. pyogenes infection and psoriasis. Also, studies are needed to evaluate the clinical efficacy of the treatment of S. pyogenes infection in decreasing the number of psoriatic events.
