Clinical characteristics of psoriatic patients with latent tuberculosis infection - 2020.

Background: Psoriasis is an immune-mediated inflammatory disease in which imbalance of the immunological response may be associated with disease severity and comorbidities. Latent tuberculosis infection (LTBI) is a growing concern for treatment of psoriasis, as the use of biologics has recently increased. Objectives: To investigate the clinical and immunological influence of LTBI on the features of psoriasis. Materials and Methods: We conducted a retrospective analysis of 300 patients with psoriasis using clinical information, including severity, comorbidities, and presence of LTBI. Serum cytokine levels were measured for immunological analysis. Results: The prevalence of psoriatic arthritis ( p = 0.001) and nail psoriasis ( p = 0.014) in patients with LTBI was significantly higher than in those without LTBI, although other data including the Psoriasis Area Severity Index showed no association. The serum levels of interleukin (IL)-6, IL-8, and IL-23A in the LTBI-positive group were higher than those in the LTBI-negative group ( p = 0.014, p = 0.025, and p = 0.004, respectively). Conclusion: LTBI may be a risk factor for the development of psoriatic arthritis during chronic inflammatory conditions induced by tuberculosis infection.
