Introduction: Granulocyte and monocyte adsorption apheresis (GMA) is usually performed weekly for refractory skin diseases, such as generalized pustular psoriasis and psoriatic arthritis (PsA).

Methods: Four patients with PsA who were refractory to previous treatments were enrolled. They received five or ten sessions of GMA. We assessed the clinical conditions of each patient and laboratory findings before and after GMA.

Results: GMA was effective in plaque-type skin eruptions in all four patients with PsA. It was also effective in joint symptoms in three patients with PsA with mild symptoms, but was ineffective in one patient with severe joint symptoms.

Conclusion: GMA may be recommended to PsA patients with skin eruptions and mild joint symptoms.

Psoriatic arthritis (PsA) is a chronic, multi-domain immune–mediated inflammatory arthritis with a high disease burden. PsA patients have significant co-morbidities like obesity, depression, fibromyalgia which can impact disease activity assessment. The management of PsA has undergone a paradigm shift over the last decade due to the availability of multiple biologic and targeted synthetic disease modifying anti-rheumatic drugs. Despite the availability of multiple therapeutic agents, it is not uncommon to find patients not responding adequately and continuing to have active disease and/or high disease burden. In our review, we propose what is “difficult to treat PsA”, discuss differential diagnosis, commonly overlooked factors, co-morbidities that affect treatment responses, and suggest a stepwise algorithm to manage these patients.

Neutrophilic inflammation is a pervasive characteristic common to spondyloarthropathies and related disorders. This inflammation manifests as Munro’s microabscesses of the skin and osteoarticular neutrophilic inflammation in patients with psoriatic arthritis, intestinal crypt abscesses in patients with inflammatory bowel disease, ocular hypopyon in anterior uveitis, and neutrophilic macroscopic and microscopic inflammation in patients with Behçet’s disease. Strong MHC class I associations are seen in these diseases, which represent so-called MHC-I-opathies, and these associations indicate an involvement of CD8 T-cell immunopathology that is not yet well understood. In this Personal View, we highlight emerging data suggesting that the T-cell-neutrophil axis involves both a T-cell-mediated and interleukin (IL)-17-mediated (type 17) recruitment and activation of neutrophils, and also a sequestration of activated neutrophils at disease sites that might directly amplify type 17 T-cell responses. This amplification likely involves neutrophilic production of IL-23 and proteases as well as other feedback mechanisms that could be regulated by local microbiota, pathogens, or tissue damage. This crosstalk between innate and adaptive immunity offers a novel explanation for how bacterial and fungal microbes at barrier sites could innately control type 17 T-cell development, with the aim of restoring tissue homoeostasis, and could potentially explain features of clinical disease and treatment response, such as the fast-onset action of the IL-23 pathway blockade in certain patients. This axis could be crucial to understanding non-response to IL-23 inhibitors among patients with ankylosing spondylitis, as the axial skeleton is a site rich in neutrophils and a site of haematopoiesis with myelopoiesis in adults.

Adsorptive granulocyte and monocyte apheresis (GMA) is an extracorporeal treatment that selectively removes activated myeloid lineage leukocytes from peripheral blood. This technique consists of a column with cellulose acetate beads as absorptive leukocytapheresis carriers, and was initially used to treat ulcerative colitis. A literature search was conducted to extract recently published studies about the clinical efficacy of GMA in patients with different skin disorders, reporting information on demographics, clinical symptoms, treatment and clinical course. Dermatological diseases, in which GMA has been performed, include generalized pustular psoriasis, pyoderma gangrenosum, palmoplantar pustular psoriasis, Behcet’s disease, Sweet’s syndrome, adult-onset Still’s disease, impetigo herpetiformis, reactive arthritis, acne and hidradenitis suppurativa syndrome, cutaneous allergic vasculitis and systemic lupus erythematosus. In most patients, GMA was started after the failure of conventional therapeutic options and it was helpful in the majority of cases. Based on the information summarized, GMA could be considered a valid non-pharmacological treatment option for patients with several dermatological conditions, which are difficult to treat with other pharmacological preparations.

Drug therapy of immune-mediated inflammatory arthropathies is not always satisfactory, and there is a risk of adverse events. Granulocyte and monocyte/macrophage apheresis (GMA) is a non-pharmacological therapeutic option that is beneficial and very well tolerated. GMA involves passing blood through a column with cellulose acetate beads to remove increased and activated myeloid lineage cells and improve the cytokine profile. The technique reduces pain and inflammation. We present four clinical reports that illustrate the clinical uses of GMA with the medical device Adacolumn® in patients with different backgrounds and immune-mediated inflammatory arthritis. The results were positive, and no adverse events were reported..

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.

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.

Psoriatic arthritis (PsA), a chronic inflammatory arthropathy associated with psoriasis, is an intractable immune disorder and refractory to pharmacological intervention. We assessed efficacy of selective depletion of myeloid lineage leukocytes in patients with PsA in a multicenter setting. A total of 20 patients with moderate to severe PsA refractory to conventional and biological disease-modifying antirheumatic drugs were included. Eligible patients had 3 points or more in the classification criteria for PsA. Each patient received five sessions, once a week, of adsorptive granulocyte and monocyte apheresis (GMA) with the Adacolumn^® . The primary efficacy outcome was 20% or more decrease in the American College of Rheumatology score 20 (ACR20). Partial responders could receive an additional five GMA sessions. Of 20 patients, two did not complete the study, nine responded to five GMA sessions and nine 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 seven of 10 (70%) and five 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 study demonstrates that GMA with the Adacolumn was effective with good safety profile in patients with PsA refractory to pharmacologicals. The results indicate a major role for myeloid leukocytes in the immunopathogenesis of PsA. A large controlled study is warranted to fully evaluate the efficacy of Adacolumn GMA in patients with PsA.
