Objective:
Red blood cell distribution width (RDW) and platelet distribution width (PDW) are reported to be associated with inflammation. We aimed to determine the association between RDW and PDW with autoimmune liver disease (ALD).
Material And Methods:
We retrospectively analyzed 126 patients who were diagnosed with ALD. Sixty-nine healthy individuals represented the control group. Characteristics and laboratory parameters of the ALD patients and control subjects were compared.
Results:
The aspartate transaminase (AST) (P < 0.001), alanine transaminase (ALT) (P < 0.001), C-reactive protein (CRP) (P < 0.001), RDW (P < 0.001) and PDW (P < 0.001) levels of the ALD group were significantly higher than those of the control subjects. RDW was significantly correlated with AST (r = 0.17, P = 0.02) and CRP (r = 0.19, P = 0.01) levels. Moreover, PDW was significantly correlated with AST (r = 0.23, P = 0.002), ALT (r = 0.23, P = 0.001) and CRP (r = 0.23, P = 0.001) levels. The sensitivity and specificity of RDW higher than 13.7% level were 76% and 62%, respectively [AUC: 0.74, P < 0.001, 95% confidence interval (CI): 0.67-0.81]. The sensitivity and specificity of PDW higher than 17.9% level were 80% and 71%, respectively (AUC: 0.85, P < 0.001, 95% CI: 0.79-0.90). The sensitivity and specificity of CRP higher than 2.9 U/l level were 92% and 85%, respectively (AUC: 0.91, P < 0.001, 95% CI: 0.86-0.95).
Conclusion:
Our study demonstrates that RDW and PDW have considerable sensitivity and specificity in determining ALD.
