Detection of specific IgE antibodies to nafamostat mesilate as an indication of possible adverse effects of leukocytapheresis using nafamostat mesilate as anticoagulant.

The aim was to determine whether adverse effects of leukocytapheresis (LCAP) are related to nafamostat mesilate (NM) as an anticoagulant. Anti-NM IgE were detected in inflammatory bowel disease (IBD) patients who were administrated LCAP in our institute. Forty-nine patients (ulcerative colitis (UC)/Crohn's disease (CD): 30/19) were evaluated.

Extracorporeal monocyte granulocytapheresis was effective for a patient of erythema nodosum concomitant with ulcerative colitis.

We report an erythema nodosum (EN) patient whose condition became apparent during the clinical course of ulcerative colitis (UC). The patient relapsed frequently in spite of taking a high dose adrenocortical steroid during his morbidity period of UC. Monocyte-granulocytapheresis (M-GCAP) was combined with 5-aminosalicylic acid 2250 mg/day peroral and once a day of steroid enema.

Poorly controlled ulcerative colitis treated by colectomy during remission induced by extracorporeal leukocyte removal therapy.

Both monocyte-granulocytapheresis (M-GCAP) and leukocytapheresis (LCAP) are categorized as extracorporeal leukocyte removal therapies (ECCTs). These therapies have been recognized as efficient adjuncts for patients of steroid-resistant ulcerative colitis (UC). This study aimed to consider the adaptation and the limitation of these new therapies from the clinical standpoint based on a case of UC showing strong resistance to high-dose continuous steroid injection therapy.

A case report: first case of filtration leukocytapheresis for a patient of aortitis syndrome associated with ulcerative colitis.

An 18-year-old woman was treated with leukocytapheresis (LCAP) for her combined ulcerative colitis (UC) and aortitis syndrome (AS). Because a close relationship between these two diseases has been suspected based on their etiological and/or pathological findings, we had hypothesized that LCAP, which has satisfactory effects on inflammatory bowel disease such as UC and Crohn's disease might be effective for both her UC and her AS. After informed consent, LCAP therapy was performed once a week for a total of 7 times.
