A 68-year-old man developed immune-related adverse event (irAE) colitis after the initiation of nivolumab and ipilimumab combination therapy for malignant melanoma. We diagnosed the patient with grade 3 irAE colitis and started prednisolone (1 mg/kg/day). Although the symptom improved once, it worsened along with the tapering of prednisolone. Therefore, we started infliximab (IFX). However, symptoms did not improve after two doses of IFX. We discontinued IFX and initiated vedolizumab (VED). Because VED alone did not improve the symptom, we started granulocyte-monocyte apheresis (GMA). Twelve weeks after the onset, the colitis was in remission. Therefore, in addition to vedolizumab, GMA may be considered in cases refractory to treatment.

Background: This multicenter observational cohort study aimed to evaluate the utilization and short-term efficacy of advanced therapy (AT) in hospitalized patients with acute severe ulcerative colitis (ASUC).

Methods: In total, 221 patients with ASUC were enrolled between August 2020 and July 2021. The primary endpoint was clinical remission (CR, defined as a patient-reported outcome score < 2 with no blood in the stool) rate on Day 7 and 14 in hospitalized patients who received corticosteroids (CS) and AT.

Results: Among patients with ASUC, 120 and 101 patients received CS or any AT as first-line treatment, respectively. The CR rates on Day 7 and 14 were 22.5% and 35.0%, respectively, in hospitalized patients who received CS as first-line treatment. Most patients who used ATs had CS-dependent or frequent recurrences. Eight different ATs (apheresis, tacrolimus, infliximab, golimumab, tofacitinib, vedolizumab, ustekinumab, and cyclosporine) were used as first-line treatment in patients with ASUC, and the CR rates on Day 7 and 14 were 16.8% and 29.7%, respectively. Twenty-five patients received the second ATs after hospitalizations, and the CR rates on Day 7 and 14 were 0% and 12%, respectively. The CR rates on Day 14 were significantly higher in patients who changed to AT than in those whose dose of CS increased (34.0% vs 10.7%, p = 0.020) among patients who had already used CS before hospitalization.

Conclusion: Most first-use ATs were effective for patients with ASUC, while second-use ATs might have had limited benefits in inducing CR. These findings may contribute to considerations for the management of hospitalized patients.

Introduction: immune checkpoint inhibitors (ICI) are increasingly used to treat several types of cancer. These drugs lead to a wide range of toxicities. Immune-related gastrointestinal adverse events are common and potentially severe. In this manuscript, we recount the real clinical experience in a tertiary center. Methods: a retrospective and observational study was conducted in adult patients under ICI treatment. Included patients had been referred to the Gastrointestinal Service of Hospital Universitario Vall d’Hebron for evaluation of severe toxicities, from January 2017 to January 2020, for whom the clinical, epidemiological and evolutive data were collected. Results: a total of 18 patients were included. Fifty-five percent received anti-programmed cell death protein 1 (PD-1)/anti-programmed death-ligand 1 (anti PD-L1), 11 % received anti-cytotoxic T lymphocyte antigen 4 (CTLA-4) and 33 % received both treatments. The toxicities were manifested as enterocolitis, microscopic colitis and gastritis. Upper gastrointestinal endoscopy was performed in seven patients; all were proved to have histological changes on duodenum biopsies. Treatment was stopped in all patients and steroids were initiated. Sixty-six per cent achieved clinical remission with steroids. Five patients received anti-TNF treatment (infliximab). Only one of the five had responded. Two anti-TNF refractory patients received ustekinumab, with an appropriate clinical response. One patient received apheresis granulocyte as concomitant treatment. A patient with a steroid-dependent course started vedolizumab. Three patients had other immune-related adverse events. Conclusion: gastrointestinal immune-related adverse events are acquiring a higher profile in daily practice and gastroenterologists play an even greater role in the management of these patients.

Objective: Primary non-response and secondary loss of response to anti-TNF agents are common in inflammatory bowel disease. Increasing drug concentrations are correlated to better clinical response and remission rates. Combination of granulocyte-monocyte apheresis (GMA) with anti-tumor necrosis factor (TNF) agents could be an option in these patients. The objective of our study was to perform an in vitro assay to determine if the GMA device can lead to infliximab (IFX) adsorption.

Patients and methods: A blood sample was obtained from a healthy control. It was incubated with three concentrations of IFX (3, 6, and 9μg/ml) at room temperature for 10min. At that time, 1ml was collected to determine the IFX concentration. Then, 10ml of each drug concentration was incubated with 5ml of cellulose acetate (CA) beads from the GMA device at 200rpm for 1h at 37°C to simulate physiological human conditions. A second sample of each concentration was collected and IFX levels were determined.

Results: No statistically significant differences were observed in the IFX levels in the blood samples before and after incubation with the CA beads (p=0.41) and after repeated measurements (p=0.31). Mean change was 3.8μg/ml.

Conclusions: The in vitro combination of GMA and IFX did not change the circulating levels of IFX at the three concentrations tested, suggesting that there is no interaction between the drug and the apheresis device in vitro and that they might be safely combined with each other.

Although anti-tumor necrosis factor-α monoclonal antibody biological preparations (BP) agents are widely used as an established treatment tool for refractory ulcerative colitis (UC), whether leukocytapheresis /granulocytapheresis (L/G-CAP) has similar beneficial impact on the disease activity remains undetermined. Furthermore, the costs defrayed for the treatment with these 2 modalities have not been compared. We retrospectively evaluated whether L/G-CAP offered sustained beneficial effects over 2-year period. The patients who had moderately to severely active UC (Rachmilewitz clinical activity index (CAI) ≧ 5) and were treated with a series (10 sessions) of L/G-CAP (n = 19) or BP (n = 7) as an add-on therapy to conventional medications were followed. Furthermore, the cost-effectiveness pertaining to the treatment with L/G-CAP and BP was assessed over 12 months. At baseline, L/G-CAP and BP groups manifested similar disease activity (CAI, L/G-CAP; 7.0 [6.0-10.0], BP; 10.0 [6.0-10.0], P = .207). The L/G-CAP and BP treatment suppressed the activity, with CAI 1 or less attained on day 180. When the L/G-CAP group was dichotomized into L/G-CAP-high and L/G-CAP-low group based on CAI values (≥3 or < 3) on day 365, CAI was gradually elevated in L/G-CAP-high group but remained suppressed in L/G-CAP-low group without additional apheresis for 2 years. Anemia was corrected more rapidly and hemoglobin levels were higher in BP group. The cost of the treatment with L/G-CAP over 12 months was curtailed to 76% of that with BP (1.79 [1.73-1.92] vs 2.35 [2.29-3.19] million yen, P = .028). L/G-CAP is as effective as BP in a substantial number of patients over 2 years. The cost for the treatment of UC favors L/G-CAP although the correction of anemia may prefer BP. Thus, L/G-CAP can effectively manage the disease activity with no additional implementation for 2 years although further therapeutic modalities might be required in a certain population with high CAI observed on day 365.

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

Aseptic abscesses (AAs) are extraintestinal manifestations of inflammatory bowel disease (IBD). IBD-associated AAs are rare in Japan. We treated a 45-year-old man with ulcerative colitis (UC)-associated AAs. During remission, multiple progressive abscesses were detected in the spleen; he underwent splenectomy because an infectious disease was suspected. Although his condition improved temporarily after splenectomy, a large liver abscess was noted, and a diagnosis of UC-associated AAs was made. Granulocytapheresis (GCAP) and infliximab (IFX) administration resolved the abscess. This is the first reported case of UC-associated AAs in a Japanese patient treated by splenectomy, GCAP, and IFX.

A 31-year-old woman with the IL36RN gene mutation developed psoriasis at 3 years old. As she had pustular psoriasis at 16 years old, she was treated with cyclosporine (Cys), resulting in remission at 20 years old. Afterwards, she had been maintained by topical treatment for long years.During the first pregnancy at the age of 29, she developed pustular psoriasis at 29 weeks
of gestation. She received one course of granulocyte / monocyte adsorption apheresis (GMA) with Cys and prednisolone (PSL), and gave birth to a girl at 33 weeks of gestation. The baby was a low birth weight child, but is healthy and has no problems in growth and development until now. However, the patient did not sufficiently improve symptoms after delivery. We thus started the treatment with infliximab (IFX) BS at 2 months postpartum. During the second pregnancy at the age of 30, we continued the IFX-BS administration. She had erythema and pustules rapidly enlarged from 23 weeks of pregnancy. Oral administration of PSL and GMA were started. However, we switched the therapy to intensive GMA (twice in a week), because the effect was insufficient. Initially, administration of IFX-BS was scheduled to end at 30 weeks of gestation, but due to unstable symptoms, we considered it was necessary to use another biologics even after 30 weeks of gestation. We switched to non-placental certolizumab pegol (CTZ) from 26 weeks of gestation and continued the administration until delivery, and she gave birth to a girl at 35 weeks of gestation. Although the baby was a low birth weight child, there was no physical abnormality and the baby was discharged after gaining weight. After delivery, administration of CTZ was discontinued and the PSL dose was gradually reduced. However,reintroduction of biologics is under consideration, because erythema and pustules still remain.

Recently, there has been a line of evidence suggesting that biologics such as infliximab and adalimumab are effective in treating intestinal BD. Moreover, new biologics targeting proteins other than tumor necrosis factor α are emerging and are under active investigation. Therefore, in this paper, we review the current therapeutic strategies and new clinical data for the treatment of intestinal BD.
