However, no relationship was found between NLR and disease severity, and anti-Dsg levels.[15] In the study of Lin et al, a low/insignificant correlation was found between PDAI and anti-Dsg1 levels, anti-Dsg3 levels, and NLR in patients with PV.[28] According to the results of our study, there was no correlation between PDAI and anti-Dsg1, anti-Dsg3 levels, and NLR; there was a significantly low correlation between PDAI and CRP. The gene discussed is DSG1; the disease is acquired polycythemia vera.
