Our findings on the serum ALB and Hb levels in recurrent UC patients were consistent with those of Ishida et al. [18] These authors reported that the average serum ALB concentration was 40.3 ± 4.9 g/L, and the average Hb concentration was 128.7 ± 19.7 g/L in active UC patients, suggesting a shared state of compromised nutritional status and the presence of anemia [18]. Here, GSTM1 is linked to anemia.
