Inflammatory Bowel Disease (IBD) is a hallmark of leukocyte infiltration, followed by the release of cytokines and interleukins. Disease progression to Ulcerative Colitis (UC) or Crohn’s Disease (CD) remained largely incurable. The genetic and environmental factors disrupt enteral bacteria in the gut, which hampers the intestinal repairing capability of damaged mucosa. Commonly practiced pharmacological therapies include 5-aminosalicylic acid with corticosteroids and tumor necrosis factor (TNF)-α. New interventions such as CDP571 and TNF-blocking RDP58 report the loss of patient response. This review discusses the non-pharmacologic selective granulocyte-monocyte-apheresis (GMA) and leukocytapheresis (LCAP) that have been proposed as treatment modalities that reduce mortality. GMA, an extracorporeal vein-to-vein technique, presents a strong safety profile case for its use as a viable therapeutic option compared to GMA’s conventional medication safety profile. GMA reported minimal to no side effects in the pediatric population and pregnant women. Numerous studies report the efficacious nature of GMA in UC patients, whereas data on CD patients is insufficient. Its benefits outweigh the risks and are emerging as a favored non-pharmacological treatment option. On the contrary, LCAP uses a general extracorporeal treatment that entraps leukocytes and suppresses cytokine release. It has been deemed more efficacious than conventional drug treatments, the former causing better disease remission, and maintenance. Patients with UC/CD secondary to complications have responded well to the treatment. Side effects of the procedure have remained mild to moderate, and there is little evidence of any severe adverse event occurring in most age groups. LCAP decreases the dependence on steroids and immunosuppressive therapies for IBD. The review will discuss the role of GMA and LCAP.

For the optimal management of refractory ulcerative colitis (UC), secondary loss of response (LOR) and primary non-response to biologics is a critical issue. This article aimed to summarize the current literature on the use of cytapheresis (CAP) in patients with UC showing a poor response or LOR to biologics and discuss its advantages and limitations. Further, we summarized the efficacy of CAP in patients with UC showing insufficient response to thiopurines or immunomodulators (IM). Eight studies evaluated the efficacy of CAP in patients with UC with inadequate responses to thiopurines or IM. There were no significant differences in the rate of remission and steroid-free remission between patients exposed or not exposed to thiopurines or IM. Three studies evaluated the efficacy of CAP in patients with UC showing an insufficient response to biologic therapies. Mean remission rates of biologics exposed or unexposed patients were 29.4 % and 44.2%, respectively. Fourteen studies evaluated the efficacy of CAP in combination with biologics in patients with inflammatory bowel disease showing a poor response or LOR to biologics. The rates of remission/response and steroid-free remission in patients with UC ranged 32%-69% (mean: 48.0%, median: 42.9%) and 9%-75% (mean: 40.7%, median: 38%), respectively. CAP had the same effectiveness for remission induction with or without prior failure on thiopurines or IM but showed little benefit in patients with UC refractory to biologics. Although heterogeneity existed in the efficacy of the combination therapy with CAP and biologics, these combination therapies induced clinical remission/response and steroid-free remission in more than 40% of patients with UC refractory to biologics on average. Given the excellent safety profile of CAP, this combination therapy can be an alternative therapeutic strategy for UC refractory to biologics. Extensive prospective studies are needed to understand the efficacy of combination therapy with CAP and biologics.

Granulocyte and monocyte adsorptive apheresis (GMA) is occasionally introduced as an alternative combination therapy after loss of response to biologics in ulcerative colitis (UC) patients. However, there have been no reports of the concomitant use of vedolizumab (VDZ) and GMA for the initial induction of UC. A 20-year-old man with refractory UC was admitted for recrudescence. VDZ monotherapy had previously been introduced but was ineffective. Therefore, he received scheduled combination of VDZ and GMA and achieved clinical remission. The combination of two different approaches to inhibit the migration of leukocytes into the inflamed tissue led to satisfactory clinical outcomes.

Based on these outcomes, combination therapy with TOF plus intensive GMA was well tolerated and may be useful for induction of clinical remission in patients with refractory UC.

Neutrophilic skin diseases are a group of disorders characterized by intense dermal infiltration of neutrophils without infection. They include a variety of diseases, such as pyoderma gangrenosum, pustular psoriasis, and palmoplantar pustulosis. We demonstrated that granulocyte and monocyte adsorption apheresis (GMA) is a useful treatment modality for such refractory skin diseases. Microarray analysis of microRNAs (miRNAs) was performed using sera of patients with neutrophilic skin diseases before and after GMA. Several miRNAs significantly increased in patients compared to control subjects. The expression of three
miRNAs decreased after apheresis, suggesting that these miRNAs might be involved in the pathogenesis of neutrophilic skin decreases. To prove the function of these miRNAs, HL-60, a human acute promyelocytic leukemia cell line, was differentiated by the treatment of alltrans retinoic acid (ATRA). When HL-60 was differentiated to neutrophilic cells, the HEstaining shows an increased cytoplasm to nucleus ratio, condensated chromatin, and nuclear segmentation. The expression of three miRNAs increased during the neutrophilic differentiation. Stimulation of ATRA-treated HL-60 by some cytokines altered miRNA expressions. Moreover, manipulation of these miRNAs changed proliferation of cultured keratinocytes. These data
suggest that miRNAs play an important role in regulating neutrophilic differentiation and proliferation of keratinocytes in case of neutrophilic disorders such as psoriasis. These miRNAs could be markers of disease severity and response of GMA.

Generalized pustular psoriasis (GPP) is a rare disease characterized by recurrent fever and
systemic flushing accompanied by extensive sterile pustules. Treatments of GPP are usually
topical corticosteroids, activated vitamin D3 ointment, ultraviolet light (UV) therapy, and
oral administration of etretinate, cyclosporine, or methotrexate. Recently, biologics such as
TNF- α; inhibitors, anti-IL-17- and anti-IL-23 antibodies are used. Pustulosis palmoplantaris
(PPP) is a chronic recurrent disorder of the palms and soles characterized by sterile intradermal
pustules. PPP often accompanies joint symptoms. In some instances, PPP is associated with
a focus of infection somewhere in the body; elimination of the infection sometimes improve
symptom. Some treatments of GPP are used for PPP. Psoriatic arthritis (PsA) is a disease
characterized by skin and nail psoriasis together with widespread musculoskeletal inflammation
such as peripheral joint disease, axial joint disease, enthesitis, and dactylitis. Treatment of
PsA is oral administration of NSAID’s, cyclosporine, methotrexate and phosphodiesterase 4
inhibitors for mild to moderate cases. Biologics; TNF- αinhibitors, anti-IL-17- and anti-IL-23
antibodies; have been approved for severe or advanced cases. Granulocyte/monocyte adsorption
apheresis (GMA) is an extracorporeal therapy designed to remove and suppress the functions
of neutrophils, macrophages and monocytes that accumulate in the inflamed tissue and are
involved in the pahogenesis. GMA may be considered as a safe treatment modality with few
side-effects for GPP, PPP and PsA. The effect and safety of GMA have been reported mostly in
case reports. Although the effect and safety of GMA were demonstrated in a multicenter study.
GMA’s utility is expected based on the mechanism of action.

The apheresis guidelines for digestive diseases are divided into the following four fields: acute liver failure (ALF); ascites; acute pancreatitis (AP); inflammatory bowel disease (IBD).

IBD: Ulcerative colitis (UC) and Crohn’s disease (CD) are the major forms of I BD. Although their etiology is still not fully understood, activated leukocytes are significant factors in their exacerbations. In Japan, granulocyte and monocyte apheresis (GMA) and leukocytapheresis (LCAP) are approved for IBD treatment. They are recommended for remission induction in UC
patients with mild-to-moderate activity, whether steroid-resistant or -dependent. Although GMA is recommended for remission induction in colonic type CD refractory to conventional therapy, its efficacy is lower than in UC patients.

Adsorptive granulocyte and monocyte apheresis (GMA) with the Adacolumn is an extracorporeal treatment, which uses cellulose acetate (CA) beads as adsorptive leucocytapheresis carriers designed to remove elevated and potentially activated myeloid lineage leucocytes. Case series studies on the clinical effectiveness of GMA on skin diseases and associated arthropathy attributable to activated myeloid lineage leucocytes returned remarkable outcome without any serious adverse events. Psoriatic arthritis (PsA) is a chronic inflammatory arthropathy associated with psoriasis. PsA is an intractable immune disorder and refractory to pharmacological intervention. Efficacy of selective depletion of myeloid lineage leucocytes in patients with PsA was assessed.in a multicenter setting. A total of 20 patients with moderate to severe PsA refractory to conventional and biological disease-modifying antirheumatic drugs were enrolled. Each patient received 5 sessions of GMA once a week. The primary efficacy outcome was 20% or more decrease in the American College of Rheumatology score 20 (ACR20). Partial responders received an additional 5 GMA sessions. Of 20 patients, 2 did not complete the study, 9 responded to 5 GMA sessions and 9 received 10 sessions. At the first evaluation 2 weeks after the last GMA session, 13 of the 20 (65.0%) patients achieved ACR20. ACR20 was maintained in 7 of 10 (70%) and 5 of 10 (50%) patients at the follow-up evaluation points 8 and 20 weeks after the last GMA session, respectively. GMA was well tolerated without any safety concern. This multicenter study demonstrated that GMA was effective with good safety profile in patients with PsA refractory to pharmacologicals, We present the results of this study and mode of action of GMA.
