Introduction: In recent years, the prevalence of inflammatory bowel diseases has been increasing in Japan due to the westernization of lifestyles. Many patients have been reported to have extra-intestinal manifestations (EIMs) at least once. Skin lesions occur with a high degree of frequency among EIMs, with erythema nodosum (EN) and pyoderma gangrenosum (PG) the main complications. Cytapheresis is again attracting attention as a treatment with few side effects. Methods: We investigated the therapeutic effect of cytapheresis on ulcerative colitis (UC) and cutaneous EIMs. Between 2008 and 2021, 240 patients with active UC had induction therapy by cytapheresis at our hospital. Results: Remission and response rates were 50.0% and 67.5%, respectively. Apheresis was performed on seven patients with PG and five patients with EN with a good response. Serious adverse events were not observed. Conclusion: This retrospective assessment of efficacy showed that EN and PG responded favorably to cytapheresis.

Pyoderma gangrenosum (PG), a chronic aseptic inflammatory skin disease characterized by skin ulcers with elevated and undermined borders, is resistant to conventional therapies. PG is elicited by activated neutrophils and macrophages and is often associated with systemic diseases such as inflammatory bowel disease, rheumatoid arthritis, aortitis syndrome, and hematopoietic disorders. This single-center study assessed the efficacy and safety of selectively depleting myeloid-lineage leukocytes in patients with PG. Patients with PG, aged 20 or over, received 5 or 10 treatment sessions of granulocyte and monocyte adsorption apheresis (GMA), once or twice a week. Treatment efficacy was assessed based on the rate of skin ulcer reduction, the visual analog scale of pain, and the physician’s global assessment of the skin lesions. A complete response (CR) was obtained in eight patients, a nearly complete response (nCR) in three patients, and a partial response (PR) in two patients. In four of the other six, the disease remained stable (SD) and in two we observed disease progression (PD). No severe adverse events were recorded. Our results suggest that GMA is a useful and safe treatment modality for PG.

Together with previous reports, concomitant GMA therapy with corticosteroids may be an effective treatment for PG.

Pyoderma gangrenosum (PG) is a neutrophilic dermatosis clinically characterized by the presence of painful skin ulcerations with erythematous. As it is frequently associated with inflammatory bowel diseases, including ulcerative colitis, gastroenterologists should be familiar with the disease including therapeutic options. Pyoderma gangrenosum is one of the neutrophilic dermatoses often complicated with ulcerative colitis. The corticosteroid and other immune modulator have been used for the treatment, however, as its disease mechanism has not been clarified, there is no additional option for those who showed poor response and refractory to the conventional therapies. Therefore, we have conducted a review focusing on the cytapheresis for PG in cases of inflammatory bowel diseases. A literature search was conducted to extract studies published in the last 20 years, with information on demographics, clinical symptoms, treatment, and the clinical course from a total of 22 cases reported and our recent case. In most patients, cytapheresis was associated with improvement or resolution of PG after failure of conventional therapeutic options such as corticosteroids, antibiotics, immunosuppressive agents and immunoglobulin. Based on the recent reports, we have summarized the clinical course of 23 cases and efficacy of cytapheresis..Cytapheresis is helpful in the majority of patients with PG refractory to medical treatment associated with inflammatory bowel diseases and could be further studied in a multicenter, randomized trial.

The section “Preparative and Therapeutic Hemapheresis” of the German Society for Transfusion Medicine and Immunohematology (DGTI) has reviewed the actual literature and updated techniques and indications for evidence-based use of therapeutic apheresis in human disease. The recommendations are mostly in line with the “Guidelines on the Use of Therapeutic Apheresis in Clinical Practice” published by the Writing Committee of the American Society for Apheresis (ASFA) and have been conducted by experts from the DACH (Germany, Austria, Switzerland) region.

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.

The disease was resistant to high doses of methylprednisolone and methotrexate and successfully treated by granulocyte and monocyte adsorption apheresis. To the best of our knowledge, this is the first report on the efficacy of granulocyte and monocyte adsorption apheresis in pyoderma gangrenosum in Europe.

 These results suggest that a combination of GMA and corticosteroids might be recommendable to induce the remission of serious PG complicated with UC.
