In conclusion, our patient’s case indicates that GMA for a patient with both active UC and COVID-19 is a safe treatment option for active UC that could lead other patients in this condition to remission.

In conclusion, our experience with the current case suggests that GMA may be useful as remission induction therapy for patients with underlying disorders who have a low
BMD and who cannot be treated with steroids. We recommend further investigations be conducted to establish a detailed consensus concerning the appropriate timing and patient selection for GMA therapy

In summary, we demonstrated the utility of FC as a biomarker for assessing ER after GMA and predicting CR at the early phase during GMA in patients with active UC. Assessing the baseline characteristics alone before GMA was not sufficient to predict CR. Our findings will benefit patients with active UC by allowing them to avoid undergoing unnecessary invasive procedures and will help establish new GMA therapeutic strategies.

Active UC is associated with gut microbiota dysbiosis. GMA therapy exerts a strong regulatory effect on the gut microbiota in patients with UC.

Our results suggest that CAP effectively induces and maintains steroid-free remission in refractory UC and re-induces steroid-free remission in patients achieving steroid-free remission after the first course of CAP.

The results support the hypothesis that patients with active UC have a better chance of clinical remission if GMA is administered as an adjunctive therapy. As regards the frequency of AEs, we found no statistically significant difference between the two groups. With regard to remission maintenance, GMA was identified as an effective alternative therapeutic option

An 18-year-old woman was admitted to our hospital with fever, diarrhea and painful skin ulcers in both pretibial areas starting 19 days earlier. The skin lesions appeared deep necrotic ulcers with violaceous undermined borders. She had been diagnosed as ulcerative colitis and primary sclerosing cholangitis (PSC) 6 and 5 years before, respectively, and had stopped having regular check-up and refused medication for years. Her clinical history and skin lesions led us to suspect of pyoderma gangrenosum (PG). The skin biopsy showed aseptic abscess formation with neutrophils infiltration in the dermis without bacteria. Thus, she was diagnosed with PG. 1 mg/kg/day of prednisolone was administered and ten sessions of granulocyte and monocyte adsorption apheresis (GMA) were started. Magnetic resonance cholangiography showed multifocal bile duct strictures due to PSC. Total colonoscopy revealed ulcerative pancolitis with spared normal mucosa in the rectum. After the treatments, her symptoms and the skin lesion improved dramatically. She was discharged on the 45th day with 25 mg/day of prednisolone. In conclusion, this is the first reported case of PG with PSC-associated colitis that showed dramatic response to the concomitant GMA therapy with corticosteroids. Together with previous reports, concomitant GMA therapy with corticosteroids may be an effective treatment for PG.

Background: Granulocyte and monocyte adsorptive apheresis (GMA) is non-pharmacological therapy which selective depletion of activated granulocytes and monocytes/macrophages from peripheral blood, and it is used as induction therapy for IBD. However, its therapeutic mechanism has not been well characterized. Recently, mucosal healing has been emerged as a therapeutic goal for IBD. It has been reported that growth factors play a role in improvement of mucosal repair and regeneration in animal colitis models, and tight junction proteins which impact mucosal permeability play a crucial role in mucosal healing. We investigated that changes in mRNA expression levels of these molecules in colonic mucosa of ulcerative colitis (UC) patients before and after GMA treatment in order to obtain further understanding of GMA therapeutic mechanisms. Methods: Thirty-two active UC patients (Mayo score ≥ 5 and Mayo endoscopic score ≥ 2) were enrolled in this study. All UC patients received 10-11 times of GMA, and colonoscopies were applied before the first GMA (preGMA) and after the last GMA (post-GMA). Assessment of GMA therapeutic efficacy and colonic mucosal healing were determined based on Mayo score. Growth factors such as EGF and HGF, and tight junction proteins such as occludin and ZO-1 mRNA expressions were determined by quantitative RT-PCR using biopsy specimen of colonic mucosa. Results: After GMA treatment, 11 patients (34.4%) achieved clinical remission, 17 patients (53.1%) showed clinical response and 4 patients (12.5%) showed non-response. All patients of the clinical remission group achieved mucosal healing, whereas none of patients in non-response group achieved mucosal healing. Baseline characteristics such as sex, location of disease, CRP, WBC and Mayo score were not significantly different according to GMA efficacy. In both pre-GMA and post-GMA, the clinical remission group showed significantly higher expressions of occludin, ZO-1 and EGF mRNA in mucosal tissue than those of the nonresponse group (P <0.05). Post-GMA, HGF mRNA expression tended to be lower in the remission group than those in non-response group. In the non-response group, levels of occludin and ZO-1 mRNA significantly decreased post-GMA compared to their pre-GMA levels (P <0.05), but they were not decreased in the clinical remission group. In contrast, HGF mRNA level decreased post-GMA compared to its pre-GMA level in the remission group, but it was not decreased in the non-response group. Conclusion: In UC patients who achieved clinical remission by GMA, expressions of EGF and tight junction molecules were higher significantly, and mRNA level of HGF decreased after GMA treatment. These results suggest that these molecules play an important role in mucosal healing, and could be helpful for choosing patients who are respond to GMA before treatment

To our knowledge this is the first report of adding GMA to restore the efficacy of infliximab in patients with LoR.  However, the efficacy outcomes following addition of a non-drug GMA to infliximab is potentially very interesting in therapeutic settings and should inspire further studies

Remission induction was more challenging in elderly UC patients. However, CAP was safe and effective for remission induction as a non-pharmacological treatment, even in elderly UC patients, after the incorporation of practical measures. Optimized and contrived CAP is still useful as the sole or concomitant treatment.
