GPT and systemic lupus erythematosus: Plasma CMV DNA viral load ≥ 1,600 copies/mL [odds ratio (OR) 4.411, 95% CI 1.871–10.402, p = 0.001], current glucocorticoids dose (equivalent to prednisolone) ≥60 mg/d (OR 2.155, 95% CI 1.071–4.334, p = 0.031), and elevated alanine transaminase (OR 3.409, 95% CI 1.563–7.435, p = 0.002) were significant clinical clues indicating CMV disease in SLE.
