In each IBD subgroup, IL-5RA expression was positively correlated with PCDAI, platelet count, ESR, hsCRP, and fecal calprotectin and negatively correlated with hemoglobin and albumin in CD; it was negatively correlated with peripheral eosinophil count and fecal calprotectin in UC and negatively correlated with hemoglobin in IBD-U (Table 3). Here, ALB is linked to inflammatory bowel disease.
