Orta şiddette ve şiddetli psoriasis hastalarında ustekinumab tedavisi sonrası inflamatuar belirteçlerde azalma

Abstract

Psoriasis is a chronic, inflammatory, and systemic disease. The disease activity is usually measured by Psoriasis Area and Severity Index (PASI), however, further objective laboratory tools are needed. Neutrophillymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR) and mean platelet volume (MPV) are objectively calculated markers that increase in inflammation. This study aimed to investigate the utility of these markers for follow-up of systemic inflammation and response to treatment. Material and methods: A total of 25 patients who had moderate or severe psoriasis vulgaris, who received ustekinumab treatment were retrospectively evaluated in the study. In patients, pre-treatment PASI, complete blood count parameters, serum CRP levels and NLR, PLR and MPV values in the follow up when they achieved PASI 75 and/or more improvement were recorded. Patients with an additional inflammatory disease or accompanying infection were excluded from the study. Results: While a statistically significant decline was recorded in NLR and PLR (p<0.05), no significant change was observed in MPV and CRP after the therapy success where patients achieved an improvement greater than or equal to PASI 75. Conclusion:We conclude that the correlation with the response to treatment and NLR and PLR levels show that these markers may be beneficial for assessment of disease severity either in combination with current scores or alone. These markers are cost effective predictors that can easily be measured in routine practice.
