In UC patients, elevated CMV-DNA was mainly associated with the severity of disease activity (P = 0.048), use of ASA/SASP (aminosalicylic acid/salicylazosulfapyridine) and corticosteroids therapy (P = 0.041 and P = 0.035, respectively), while other factors, such as age, sex, smoking, alcohol consumption, type of diet, fever, anemia, albumin level, disease location, treatment with immunosuppressive agents had not shown significant association (P > 0.05). Here, ALB is linked to anemia (phenotype).
