Background
Granulocyte and Monocyte Adsorption Apheresis (GMA) is one of the valuable non-immunosuppressive therapies in the treatment of ulcerative colitis (UC). However, due to the limited number of facilities where GMA can be performed, there are few reports on the combined effects of GMA and prednisolone (PSL), the frequency of GMA implementation or predictive factors for the effectiveness. In this study, we examined the combined effect of GMA and PSL as a remission induction therapy, the frequency of GMA and predictive factors.

Methods
A retrospective observational study was conducted at Kushiro Rosai Hospital. We analyzed clinical data from UC patients who underwent GMA from February 2015 to May 2023.

Results
The study included 54 patients (30 males and 24 females), with a median age of 48 years and a median disease duration of 2 years. The median Lichtiger-CAI (L-CAI) was 8. There were 43 patients of pancolitis. There were 51 biologics-naïve patients and 3 biologics-experienced patients. Concomitant medications included 5-ASA agents in 21 patients, immunomodulators in 7 patients, and PSL in 31 patients. The median CRP was 1.19 mg/dl and the median albumin was 3.5 g/dl. Adverse events were observed in 3 patients (fatigue, dizziness, palpitations). The median number of GMA sessions was 10, with 33 patients undergoing twice weekly and 9 patients three times weekly. The clinical remission rate was 80% (43/54), and the clinical response rate was 89% (48/54), with a significant improvement in the median L-CAI from 8 to 3 before and after GMA (P<0.001). In the comparison between the PSL concomitant group and the non-PSL group, the clinical remission rate was 83.9% (26/31) in PSL group and 73.9% (17/23) in non-PSLgroup (P=0.369). The clinical response rate was significantly higher in the PSL group (87% (27/31)) than in non-PSL group (52.2% (12/23)) (P=0.004). There was no significant difference in the clinical remission/response rate between the group that underwent GMA twice a week (76.9% (30/39)/84.6% (33/39)) and three times a week (77.8% (7/9)/77.8% (7/9)). In univariate analysis, biologics-naïve was extracted as a contributing factor to clinical remission. The cumulative remission rate at 52 weeks was 72% overall. There was no significant difference in the cumulative remission rate between the PSL group (76.8%) and the non-PSL group (67.6%) (P=0.524). There was also no significant difference between the twice-weekly group (75%) and the three-times-weekly group (57.1%) (P=0.236). Conclusion GMA for UC was found to be useful and safely performed as a remission induction therapy. Concomitant use of PSL increased the clinical response rate. The frequency of GMA showed that three times per week was as effective as two times per week.

Aim: Granulocyte and monocyte apheresis (GMA) is a potential therapeutic option when combined with various drugs for treatment of ulcerative colitis (UC). In this study, we analyze the efficacy and safety of GMA combined with vedolizumab (VDZ) during induction in patients with moderate-severe UC and incomplete response to steroids.

Patients and methods: Single-center retrospective review of patients receiving GMA+VDZ. Data on the disease and previous treatments were collected. Clinical response was classified as no response, response without remission, and remission. Available data on biochemical and endoscopic response were included. Adverse events (AEs) were recorded.

Results: The study population comprised 6 patients with UC who had received GMA+VDZ during induction after failure of an anti-TNF agent. The median number of GMA sessions was 5 (IQR 4-5; 3-10). All the patients received VDZ 300mg iv at 0, 2, and 6 weeks, and 5 (83%) received an additional dose at week 10. During maintenance, all the patients continued VDZ iv every 8 weeks. The median follow-up was 57.6 months (IQR: 39-74). Four of the 6 patients achieved clinical remission after GMA+VDZ and continued in deep remission until the end of follow-up. A median, non-significant decrease of 1378μg/g (IQR: 924-5778μg/g) was observed for calprotectin and 42.2mg/l (IQR: 15.3-113.5) for CRP vs. baseline. No patient underwent colectomy. No treatment-related AEs were observed.

Conclusions: GMA+VDZ during induction can be effective and safe in selected patients with moderate-severe UC and partial response to steroids.

Granulocyte and monocyte adsorption apheresis (GMA) is an extracorporeal circulation therapy that removes activated granulocytes and monocytes, which can be easily introduced in clinics and hospitals where hemodialysis is performed. Its safety profile  allows for its administration without screening and for its concomitant use with other therapies, indicating that GMA can be a good additional option for GPP treatment. However, the evidence for its efficacy and safety is limited because of the rarity of GPP. Furthermore, its immediate impact on GPP has not been assessed yet. Therefore, we report our real-world experience of 14 patients with GPP treated with GMA after systemic treatment.GMA can be administered with other systemic therapies, including biologics and conventional therapy (objective A). Furthermore, its good safety profile allows GMA administration to a wide range of patients, including elderly patients and those with complications, possible active infection, or malignancy (objectives B and C). Moreover, our study revealed an immediate significant improvement in BT, accompanied by slight decreases in the WBC count and CRP level, indicating that GMA contributes to the rapid suppression of acute inflammation in patients with GPP.
