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.

To our best knowledge, this is the first report of adding a non-drug GMA to restore the efficacy of infliximab. The outcomes, albeit in three cases, are relevant in therapeutic settings and should inspire further studies in a larger number of patients.

Background: This is the first report on a case of Crohn’s disease (CD), who was successfully maintained with a combination of infliximab (IFX) and selective depletion of granulocytes/monocytes by adsorption (GMA). Case: A 33-year-old female with CD activity index (CDAI) 294.2 responded to iv IFX (5mg/kg) administered at weeks 0, 2, and 6 in combination with 3000 mg/day oral 5-aminosalicylic acid (5-ASA; CDAI = 118). Then IFX at 8 week intervals was given as maintenance therapy. Two weeks before the 5th scheduled IFX, the patient worsened with an increase in stool frequency and a rise in CDAI. GMA was administered at weeks 5, 6, and 7 after her 6th iv IFX. Her CDAI decreased from 166.2 to 126.3 and 111.9 before 2nd and 3rd GMA sessions. She received her 7th iv IFX while the CDAI was 83.6. GMA course was repeated before 8th and 9th IFX. The patient remained in stable clinical and endoscopic remission without experiencing any serious side effect. After achieving mucosal healing, the patient decided to cease IFX therapy while continuing with GMA. Conclusions: IFX appears to induce and maintain remission of CD, but it may lose its efficacy after repeated administration. GMA is safe and by selectively depleting elevated/activated leukocytes may be a useful adjunct for IFX efficacy.
