Neutrophil / Iymphocyte ratio, platelet / Iymphocyte ratio, mean platelet volume and C-reactive protein values in psoriatic arthritis patients

Aim: Studies have shown that neutrophil / lymphocyte ratio (NLR), platelet / lymphocyte ratio(PLR), mean platelet volume(MPV) andC-reactive protein(CRP) are higher in psoriatic arthritis patients than in the control group. In this study, NLR, PLR and MPV values ofpatients with psoriatic arthritis were calculated and if these parameters were related to CRP levels.Material and Methods: 74 psoriatic arthritis patients and 77 healthy controls without any systemic, infectious and autoimmunediseases were included in the study. Patients were divided into two groups according to their CRP values: normal (0-0.5 mg / dl) andhigh (> 0.5 mg / dl)Results: NLR, MPV and CRP values in the patient group were significantly higher than the control group. PLR value in the patientgroup was higher than the control group but the difference between them was not statistically significant. There was a statisticallysignificant relationship between CRP and NLR and MPV values in psoriatic arthritis patients.Conclusion: Since NLR and MPV were significantly higher in psoriatic arthritis patients than in the control group and there was astatistically significant relationship with CRP elevation, it was thought that they were appropriate parameters to show inflammationin patients with psoriatic arthritis.
