ANXA5 and systemic lupus erythematosus: There are significant differences of apoptosis markers in annexin V of leukocytes (SLE vs. SJS, p = 0.029), neutrophils (SLE vs. SJS, p = 0.004), and monocytes (SLE vs. SJS, p = 0.036) during the post hoc analysis, despite no difference in absolute numbers of leukocytes, neutrophils, and monocytes between SLE and SJS patients.
