Background: The number of the elderly patients of ulcerative colitis (UC) is growing as the population ages. Because elderly patients with UC sometimes become refractory to treatment, it is important to select an appropriate induction therapy for elderly patients at the early phase of UC disease. To predict which therapy is effective before treatment will be useful for the decision of later therapeutic strategy. Granulocyte and monocyte adsorptive apheresis (GMA) that was developed for selective depletion of activated granulocytes and monocytes/
macrophages from peripheral blood is non-pharmacological therapy for inflammatory bowel disease. It is beneficial than the other therapy in the point that it has fewer side effects. GMA is effective and safe as induction therapy in UC, and commonly used in Asia and north Europe. GMA is one of hopeful candidate of elderly therapy. We investigated the relationship between therapeutic efficacy of GMA and age, and examined whether mRNA expressions of cytokines and chemokines in colonic mucosa showed presence of age-related change. Methods: Thirty-two active UC patients, mean age 36.7 years, range 14-70 years, were enrolled in this study. All patients received 10 or 11 times of GMA, and colonoscopies were applied before the first GMA and after the last GMA. Assessment of disease activity and colonic mucosal healing were determined based on Mayo score. In this study, elderly patients were defined as those >55 years of age. mRNA expressions of cytokines and chemokines were determined by quantitative RT-PCR using biopsy specimen of colonic mucosa. Results: There were no significant differences in sex, duration of disease, location of disease, CRP, WBC and Mayo score before the first GMA treatment between elderly group and non-elderly group. After the last GMA session, the ratios of mucosal healing in elderly group and non-elderly group were 2 of 6 (33.3%) and 16 of 26 (61.5%), respectively. In all patients, before treatment of GMA, mucosal healing group showed significantly higher mRNA expression of inflammatory cytokines and chemokines such as MIP-1β, TNFα, IL1β and IL8 in colonic mucosal tissue than that of non-mucosal healing group (P <0.05). In particular, in elderly group, the degree of mRNA expression of MIP-1β and IL23 in colonic mucosa before GMA treatment was higher in mucosal healing group than in non-mucosal healing group (P <0.05). High expressions of MIP-1β and IL23 showed sensitivity, specificity, positive predictive value and negative predictive value of 100% as a marker of mucosal healing after GMA in elderly group. Conclusion: Mucosal IL23 and MIP-1β mRNA expression before treatment in elderly were significantly higher in responder than non-responder to GMA treatment. We propose that measuring of expression of these molecules is useful to expect therapeutic efficacy of GMA in elderly patients with UC.

 She is the oldest reported case of GPP with a deficiency of interleukin-36 receptor antagonist (DITRA), although GPP in DITRA has been suggested to usually occur in younger cases with no pre-existing psoriasis vulgaris.
