Abstract
Leukocytes are thought to play an important role in the pathogenesis of inflammatory bowel diseases; granulocyte-monocyte adsorptive (GMA) apheresis, an extracorporeal technique aimed at removing activated circulating leukocytes from the blood, may represent a safe and effective therapeutic tool in these patients. The Italian Registry of Therapeutic Apheresis performed an observational, multicentric study involving 24 Gastroenterology Units. In this study, laboratory data and clinical outcomes of 230 patients (148 males, mean age 43.5 years) affected with ulcerative colitis (UC, n = 194) or Crohn's disease (CD, n = 36) who underwent one or more cycles of GMA were analyzed. Each cycle consisted of five GMA treatments. The patients were followed up for a mean of 8.7 (min. 3 to max. 12) months. At 3 months, positive outcome was achieved in 77.7% of UC patients (72.0% remission, 5.7% clinical response) and 61.3% of CD patients (54.8% remission, 6.5% clinical response). The cumulative proportion of positive outcome at 12 months was 87.1% for UC patients (83.7% remission, 3.4% clinical response) and 77.4% for CD patients (74.2% remission, 3.2% clinical response). No single clinical or laboratory parameter among those analyzed (age, sex, disease characteristics, history of smoking, medication history, baseline values of clinical activity index (CAI)/Crohn's disease activity index (CDAI), hemoglobin, white blood cells count, and erythrocyte sedimentation rate) was independently associated with clinical outcome. The procedure was well tolerated with no significant adverse effects registered.

Abstract
BACKGROUND AND AIMS Severe alcoholic hepatitis (SAH) is an inflammatory response with multiple morbidity factors like leucocytosis, hepatomegaly, renal failure, hepatic encephalopathy, endotoxemia, and has a high mortality rate. Accordingly, identifying therapeutic interventions that can support prognosis is the goal of research. METHODS Questionnaires were sent to 1234 medical institutions asking for information on patients with SAH during 2004 to 2008 including patients' demography, disease profile and the therapeutic interventions patients had received during hospitalization. RESULTS Twenty-nine hospitals had treated SAH patients, and provided full demographic data on 62 patients. Twenty-seven patients had received no treatment, 10 patients had received granulocytes/monocytes apheresis (GMA) to deplete elevated myeloid linage leucocytes, the rest had received one or more of the following treatments, corticosteroids, plasma exchange (PE) and haemodialysis (HD). Further, 23 patients had died and 39 had survived within 100 days of hospitalization. Serum creatinine (Cr) was higher in patients who had died vs patients who had survived (P=0.026). Likewise, patients with white blood cells (WBC) ≥ 10(4)/μL had higher mortality rate vs patients with WBC<10(4)/μL (P=0.039). GMA in patients with WBC ≥ 10(4)/μL showed 100% prognosis vs patients with WBC ≥ 10(4)/μL who did not receive GMA (P=0.0007). Corticosteroids, PE and HD did not significantly impact prognosis of SAH patients. CONCLUSIONS Our perception is that, patients with elevated myeloid leucocytes benefit most from GMA, while PE appears to support patients with coagulation deficiency or high plasma bilirubin and HD has indication in patients with high Cr.

Abstract
PURPOSE The use of selective leukocytapheresis for the treatment of ulcerative colitis (UC) has been evaluated in several open and controlled trials, with varying outcomes. A meta-analysis was performed to better assess the efficacy and safety of selective leukocytapheresis as supplemental therapy compared with conventional pharmacotherapy in patients with UC. METHODS All randomized trials comparing selective leukocytapheresis supplementation with conventional pharmacotherapy were included from electronic databases and reference lists. A meta-analysis that pooled the outcome effects of leukocytapheresis and pharmacotherapy was performed. A fixed effect model or random effect model was selected depending on the heterogeneity test of the trials. RESULTS Nine randomized controlled trials met the inclusion criteria contributing a total of 686 participants. Compared with conventional pharmacotherapy, leukocytapheresis supplementation presented a significant benefit in promoting a response rate (OR, 2.88, 95% CI: 1.60-5.18) and remission rate (OR, 2.04; 95% CI, 1.36-3.07) together with significant higher steroid-sparing effects (OR, 10.49; 95% CI, 3.44-31.93) in patients with active moderate-to-severe UC by intention-to-treat analysis. Leukocytapheresis was more effective in maintaining clinical remission for asymptomatic UC patients than conventional therapy (OR, 8.14; 95% CI, 2.22-29.90). The incidence of mild-moderate adverse effects was much less frequent in the leukocytapheresis groups than conventional pharmacotherapy groups (OR, 0.16; 95% CI, 0.04-0.60). Few severe adverse events were observed. CONCLUSIONS Current data indicate that leukocytapheresis supplementation may be more efficacious on improving response and remission rates and tapering corticosteroid dosage with excellent tolerability and safety than conventional pharmacotherapy in patients with UC. In addition, more high-quality randomized controlled trials are required to confirm the higher efficacy of leukocytapheresis in patients with UC.

Daily granulocyte and monocyte adsorptive apheresis in patients with active ulcerative colitis: a prospective safety and feasibility study. J Gastroenterol 2011; 46:1003-9. [PMID: 21681409 DOI: 10.1007/s00535-011-0428-4] [Citation(s) in RCA: 12] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/16/2011] [Accepted: 05/08/2011] [Indexed: 02/04/2023]
Abstract
BACKGROUND This prospective study was to assess the safety and feasibility of daily granulocyte and monocyte adsorptive apheresis (GMA) therapy in patients with active ulcerative colitis (UC). METHODS Thirty consecutive patients with moderately or severely active UC received daily GMA treatment (5 sessions over 5 consecutive days) with the Adacolumn. Adverse events (AE), patient tolerability, and clinical symptoms were monitored daily. RESULTS Sixteen patients (53%) experienced AE during at least one GMA session. The most frequent AE was mild headache followed by fatigue and fever. None of the AE was serious, and all patients completed the 5 consecutive GMA sessions. Clinical symptoms (stool frequency and/or rectal bleeding) were improved in 21 patients (70%) during the course of GMA therapy. Clinical remission defined as normal stool frequency and no rectal bleeding was achieved in 7 patients (23%) after 5 GMA sessions. Seven of 20 patients (35%) with moderately active disease achieved clinical remission, whereas none of the 10 patients with severely active disease achieved clinical remission. Total and differential leukocyte counts, platelet count, and hemoglobin level did not significantly change, but C-reactive protein level significantly decreased during the course of GMA therapy. CONCLUSIONS This is the first report on daily GMA in the treatment of patients with UC. Daily GMA was safe and well tolerated without serious AE. Furthermore, daily GMA was associated with rapid improvement of clinical symptoms in patients with moderately active UC. However, controlled trials are warranted to assess a definite efficacy for daily GMA therapy.

Abstract
Granulocyte and monocyte adsorption apheresis (GMA) is one therapeutic option for induction of remission in patients with inflammatory bowel diseases. Recently intensive GMA (2 sessions per week) was reported to be strikingly better than weekly GMA, both in remission rate and time to remission. Here we report two cases of Crohn's disease refractory to weekly GMA who responded to intensive GMA. One patient had not received immunosuppressive therapy while the other had been refractory to combination therapy with infliximab and azathioprine. Intensive GMA induced remission in these 2 patients. Intensive GMA may represent a therapeutic choice for remission induction and maintenance with infliximab.

Abstract
Patients with active inflammatory bowel disease (IBD) have elevated and activated myeloid leucocytes which infiltrate the colonic mucosa in vast numbers. Myeloid leucocytes such as the CD14(+) CD16(+) monocytes are major sources of tumour necrosis factor (TNF)-α, and therefore selective granulocyte/monocyte (GM) adsorption (GMA) should promote remission or enhance efficacy of pharmacological therapy. However, studies in IBD have reported both impressive as well as disappointing efficacy outcomes, indicating that patients' demographic factors might determine responders or non-responders to GMA. Nonetheless, this non-drug intervention has an excellent safety profile, and therapeutic GMA is expected to expand. In this review, attempts have been made to compile an update on the mode of actions (MoA) of the Adacolumn GMA. The MoA of GMA appears to be more than adsorption of excess neutrophils and TNF-producing CD14(+) CD16(+) monocytes per se. Adsorbed GMs release interleukin (IL)-1 receptor antagonist, hepatocyte growth factor and soluble TNF receptors, which are anti-inflammatory. Additionally, a sustained increase in lymphocytes including the regulatory CD4(+) CD25(+) T cells (lymphocyte sparing) is seen post-GMA. The impact of GMA on the immune system is potentially very interesting in the context of treating immune-related diseases. Future studies are expected to add intriguing insights to the MoA of GMA.

Abstract
BACKGROUND AND OBJECTIVE This study evaluated the feasibility and safety of granulocytapheresis (GCAP) in inducing and maintaining remission in refractory Crohn's disease. The relationship between the clinical outcomes and the location (ileal or ileocolonic) of disease was also assessed. PATIENTS We evaluated 16 patients with ileal location (group A), 14 with ileocolonic location (group B). The patients underwent five sessions (1 session/wk) of GCAP (Adacolumn(TM)). CDAI was measured at the end of the GCAP, at 6, 9 and 12 months. RESULTS AND CONCLUSIONS No major complications were observed. At the end of GCAP, 19 (63.3%) patients showed a clinical remission: 10 (62.5%) in group A versus 9 (64.2%) in group B. At 6 months, 16 (53.3%) of the cases had maintained remission: 9 (56.2%) in group A versus 7 (50.0%) in group B. At 9 months, 13 (43.3%) patients had maintained remission: 7 (43.7%) in group A versus 6 (42.8%) in group B. At 12 months, 12 (40%) patients were still in clinical remission: 7 (43.7%) in group A versus 5 (35.7%) in group B. Risk of relapse was not related to disease location. The procedure was well tolerated and feasible in an important percentage of Crohn's disease patients.

Abstract
BACKGROUND During active ulcerative colitis (UC), vast numbers of granulocytes, monocytes/macrophages (GM) infiltrate the mucosal tissue and can potentially exacerbate inflammation and injury. Accordingly, we were interested to see if selective depletion of GM by adsorption (GMA) impacts mucosal healing (MH) in UC patients. METHODS In all, 124 patients with clinically and endoscopically active UC received 5 or 10 GMA sessions at one or two sessions/week. The endoscopic severity of mucosal inflammation at entry and 1 week after the last GMA session were scored as follows: 0 = normal mucosa and inactive disease; 1 = mild inflammation; 2 = moderate inflammation; 3 = severe inflammation. Likewise, a score 0 or 1 at post-GMA course was defined as MH. RESULTS At entry the endoscopic severity of the mucosal inflammation was 2 in 100 patients (81%) and 3 in 24 patients (19%). Following the course of GMA, 56 patients (45%) achieved clinical remission (normal stool frequency and no rectal bleeding). Thirty-four of these 56 responders achieved MH; 32 (94%) of the 34 patients with MH had an endoscopic score of 2 (moderate inflammation) at entry. The maintained clinical remission rate was significantly higher in the 34 patients who achieved MH as compared with 22 patients who achieved clinical remission without MH (P = 0.0005). CONCLUSIONS MH is achieved more frequently in patients with moderate than with severe endoscopic severity at entry. Further, patients with MH have a reduced risk of future clinical relapse as compared with patients who achieve remission without MH.

Abstract
BACKGROUND AND OBJECTIVE Elevated/activated myeloid leucocytes, like the CD14(+)CD16(+) monocytes are sources of TNF-α, and therefore, selective depletion of these cells by granulocyte/monocyte (GM) adsorption (GMA) should promote remission or enhance drug efficacy. However, studies in ulcerative colitis (UC) reported contrasting efficacy, from an 85% to statistically insignificant level. We investigated patients' demography in responders and non-responders. METHODS In 120 UC patients, 61 steroid naive and 59 steroid dependent, we looked for entry clinical or endoscopic features to identify responders (or non-responders) to GMA. Patients received up to an 11 Adacolumn GMA sessions over 12 weeks. Patients were clinically and endoscopically evaluated, allowing each patient to serve as her/his own control. Immunohistochemistry on colonic biopsies was to reveal the impact of GMA on leucocyte infiltration of the mucosa. RESULTS Entry average clinical activity index (CAI) was 12.6, 10-16. An 80 of 120 patients responded (CAI≤4); 45 steroid naïve (73.8%) and 35 steroid dependent (59.3%). Over 900 biopsies were processed. Infiltrating leucocytes were overwhelmingly polymorphonuclear and macrophages around and within crypt abscesses. There was a marked reduction of infiltrating leucocytes in responders. Most non-responders had extensive colonic lesions with virtually no mucosal tissue left at the lesions. CONCLUSIONS Steroid naïve patients with short duration of UC were the best responders, while patients with deep colonic lesions and extensive loss of the mucosal tissue were non-responders.

Abstract
The American Society for Apheresis (ASFA) Apheresis Applications Committee is charged with a review and categorization of indications for therapeutic apheresis. Beginning with the 2007 ASFA Special Issue (fourth edition), the subcommittee has incorporated systematic review and evidence-based approach in the grading and categorization of indications. This Fifth ASFA Special Issue has further improved the process of using evidence-based medicine in the recommendations by refining the category definitions and by adding a grade of recommendation based on widely accepted GRADE system. The concept of a fact sheet was introduced in the Fourth edition and is only slightly modified in this current edition. The fact sheet succinctly summarizes the evidence for the use of therapeutic apheresis. The article consists of 59 fact sheets devoted to each disease entity currently categorized by the ASFA as category I through III. Category IV indications are also listed.

Abstract
INTRODUCTION Monocytes/macrophages accumulate in the rheumatoid (RA) synovium where they play a central role in inflammation and joint destruction. Identification of molecules involved in their accumulation and differentiation is important to inform therapeutic strategies. This study investigated the expression and function of chemokine receptor CCR9 in the peripheral blood (PB) and synovium of RA, non-RA patients and healthy volunteers. METHODS CCR9 expression on PB monocytes/macrophages was analysed by flow cytometry and in synovium by immunofluorescence. Chemokine receptor CCR9 mRNA expression was examined in RA and non-RA synovium, monocytes/macrophages from PB and synovial fluid (SF) of RA patients and PB of healthy donors using the reverse transcription polymerase chain reaction (RT-PCR). Monocyte differentiation and chemotaxis to chemokine ligand 25 (CCL25)/TECK were used to study CCR9 function. RESULTS CCR9 was expressed by PB monocytes/macrophages in RA and healthy donors, and increased in RA. In RA and non-RA synovia, CCR9 co-localised with cluster of differentiation 14+ (CD14+) and cluster of differentiation 68+ (CD68+) macrophages, and was more abundant in RA synovium. CCR9 mRNA was detected in the synovia of all RA patients and in some non-RA controls, and monocytes/macrophages from PB and SF of RA and healthy controls. CCL25 was detected in RA and non-RA synovia where it co-localised with CD14+ and CD68+ cells. Tumour necrosis factor alpha (TNFα) increased CCR9 expression on human acute monocytic leukemia cell line THP-1 monocytic cells. CCL25 induced a stronger monocyte differentiation in RA compared to healthy donors. CCL25 induced significant chemotaxis of PB monocytes but not consistently among individuals. CONCLUSIONS CCR9 expression by monocytes is increased in RA. CCL25 may be involved in the differentiation of monocytes to macrophages particularly in RA.

Abstract
Background Patients with IBD and chronic inflammation refractory to conventional therapy often demonstrate higher risk of serious complications. Combinations of immunosuppression and biological treatment as well as surgical intervention are often used in this patient group. Hence, there is need for additional treatment options. In this observational study, focused on re-treatment and long-term results, Granulocyte/Monocyte Adsorption (GMA, Adacolumn®) treatment has been investigated to study efficacy, safety and quality of life in IBD-patients with chronic activity. Methods Fifteen patients with ulcerative colitis and 25 patients with Crohn's disease, both groups with chronically active inflammation refractory to conventional medication were included in this observational study. The patients received 5-10 GMA sessions, and the clinical activity was assessed at baseline, after each completed course, and at week 10 and 20 by disease activity index, endoscopy and quality of life evaluation. Relapsed patients were re-treated by GMA in this follow-up study up to 58 months. Results Clinical response was seen in 85% and complete remission in 65% of the patients. Ten patients in the UC-group (66%) and 16 patients in the CD-group (64%) maintained clinical and endoscopic remission for an average of 14 months. Fourteen patients who relapsed after showing initial remission were re-treated with GMA and 13 (93%) went into a second remission. Following further relapses, all of seven patients were successfully re-treated for the third time, all of three patients for the fourth time and one for a fifth time. Conclusions IBD-patients with chronic inflammation despite conventional therapy seem to benefit from GMA. Re-treatment of relapsing remission patients seems to be effective.

Adsorptive depletion of alpha4 integrin(hi)- and CX3CR1hi-expressing proinflammatory monocytes in patients with ulcerative colitis. Dig Dis Sci 2010; 55:1886-95. [PMID: 19908144 DOI: 10.1007/s10620-009-0974-2] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2009] [Accepted: 08/28/2009] [Indexed: 02/06/2023]
Abstract
BACKGROUND Two main functionally distinct monocytes phenotypes are known: the CD14(hi)CD16(-) "classical" and the CD14(+)CD16(+) "proinflammatory" phenotypes. The latter phenotype is elevated in patients with ulcerative colitis (UC) and is suspected to have a major role in the immunopathogenesis of UC. AIM To selectively deplete circulating proinflammatory CD14(+)CD16(+) monocyte phenotype. METHODS Seven corticosteroid-naïve patients with UC (clinical activity index = 8.7 +/- 1.3) and seven healthy subjects were included. In patients with UC, granulocyte/monocyte adsorption (GMA) was done with an Adacolumn that selectively adsorbs leucocytes of the myeloid lineage. Blood from all subjects at baseline and from the patients immediately after the first GMA session was processed. Isolated monocytes were subjected to fluorescence-activated cell sorter analyses. RESULTS The seven UC patients achieved remission (CAI <or=4) after 5-10 GMA sessions. GMA induced a strong fall in the ratio (%) of CD14(+)CD16(+) to CD14(hi)CD16(-) monocytes, from 10.0 +/- 1.4 to 3.0 +/- 0.9. Further, expressions of alpha4 integrin (374.8 +/- 26.1 mean fluorescence intensity, MFI) and CX(3)CR1 (49.5 +/- 4.6 MFI) were significantly high on CD14(+)CD16(+)monocytes as compared with on CD14(hi)CD16(-) monocytes (169.2 +/- 17.2 and 33.2 +/- 3.6 MFI, respectively). Additionally, GMA significantly increased the ratio of the CD14(hi)CD16(-)CCR2(low) "immature" monocytes from 3.74 +/- 0.62 to 8.11 +/- 0.56 MFI. CONCLUSIONS We found high expressions of alpha4 integrin and CX(3)CR1 on monocytes in patients with active UC, known to promote the extravasation of CD14(+)CD16(+) monocytes into the mucosa. GMA effectively depletes CD14(+)CD16(+) monocytes and concomitantly increases CD14(hi)CD16(-)CCR2(low) "immature" monocytes; thus GMA was associated with the emergence of less inflammatory monocyte phenotype in circulation.

Abstract
The preliminary studies for developing a second generation granulocytapheresis (G-CAP) column were made. In the past, the G-CAP column has been used for the treatment of ulcerative colitis and rheumatoid arthritis. However, recent clinical studies have revealed that the therapeutic effects of the G-CAP column are not significant compared with those of the sham column. These results were considered to be due to insufficient reduction of granulocytes. Thus, development of a better granulocyte removal column was attempted. Realizing that white cells adhered on small-diameter synthetic fibers of 1-2 microm, small diameter cotton fibers were subjected to the studies of their granulocyte-removing capabilities. Three types of cotton, Pakistani, Australian and Egyptian cottons, were evaluated using normal human blood in vitro. Miniature columns were made of each fiber, and CBC and WBC differentiation was compared between pre- and post-filtered blood. The Egyptian cotton removed leukocytes, especially granulocytes, the most efficiently of the three types of cotton. The Egyptian cotton's granulocyte adhesion properties were not altered after different chemical treatments. A 4-ml column of packaged Egyptian cotton with a density of more than 0.125 g/ml could remove granulocytes effectively up to 80 ml of blood passages. Based upon these studies, second generation G-CAP could be carried out with Egyptian cotton fibers as a scaled-up clinical module.

Abstract
OBJECTIVES Granulocyte and monocyte adsorptive apheresis (GMA) has shown efficacy in patients with active ulcerative colitis (UC). However, with routine weekly treatment, it may take several weeks to achieve remission, and to date, the efficacy of a more frequent treatment schedule remains unknown. The aim of this study was to assess the clinical efficacy and safety of intensive GMA treatment in patients with active UC. METHODS This was an open-label, prospective, randomized multicenter study to compare an intensive, two GMA sessions per week, with the routine, one GMA session per week. A total of 163 patients with mild-to-moderately active UC were randomly assigned to routine weekly treatment or intensive treatment. The maximum number of sessions of GMA permitted was 10. However, when patients achieved remission, GMA was discontinued. Remission rate at the end of the study, time to remission, and adverse events were assessed in both groups. RESULTS Of the 163 patients, 149 were available for efficacy analysis as per protocol, 76 were in weekly GMA, and 73 were in intensive GMA. At the end of the study period, clinical remission was achieved in 41 of 76 patients (54.0%) in weekly GMA and in 52 of 73 patients (71.2%) in intensive GMA (P=0.029). The mean time to remission was 28.1+/-16.9 days in the weekly GMA treatment group and 14.9+/-9.5 days in the intensive GMA group (P<0.0001). Intensive GMA was well tolerated without GMA-related serious adverse side effects. CONCLUSIONS Intensive GMA in patients with active UC seems to be more efficacious than weekly treatment, and significantly reduced the patients' morbidity time without increasing the incidence of side effects.

Abstract
Ulcerative colitis is a chronic inflammatory disease that affects the colon and rectum. Its pathogenesis is probably multifactorial including the influx of certain cytokines into the colonic mucosa, causing disease activity and relapse. The hypothesis of removing such cytokines from the circulation by leukocytapheresis was implemented to reduce disease activity, maintain remission, and prevent relapse. Many recent reports not only in Japan, but also in the West, have highlighted its beneficial effects in both adult and pediatric patients. Large placebo-controlled studies are needed to confirm the available data in this regard. In this article, we shed some light on the use of leukocyte apheresis in the management of autoimmune diseases, especially ulcerative colitis.

Abstract
BACKGROUND/AIM The Adacolumn selectively depletes granulocytes and monocytes/macrophages, which are thought to be part of the immunopathogenesis of ulcerative colitis. This work aims at evaluating the safety and clinical efficacy of the Adacolumn in patients with ulcerative colitis in large population-based data sets. METHODS The Adacolumn post marketing surveillance in Japan was undertaken on 697 patients in 53 medical institutions over 7 years from 29 October 1999 to 28 October 2006. Clinical efficacy and safety data were provided by patients' physicians in the participating institutes. RESULTS Safety was evaluated in all the 697 patients and efficacy in 656 patients. At entry, 92% of the patients were on salicylates, 74% on prednisolone and only 9% on immunomodulators. Approximately 40% of patients had severe ulcerative colitis and over 70% had ulcerative colitis that was refractory to conventional medications. There was no serious adverse events; mild to moderate adverse events were seen in 7.7% of the patients. The overall response (remission or significantly improved) was 77.3%; the remission rate based on clinical activity index was 71.1%, while 17.1% remained unchanged and 5.6% worsened. Patients were subgrouped into severe, moderate and mild ulcerative colitis based on clinical activity index (n=578), the response rates were 63.2%, 65.7% and 80.4%, respectively (P<0.001). Endoscopic assessment of efficacy showed very significant mucosal healing, Matts' endoscopic index improved from 3.2+/-0.04 to 2.1+/-0.7 (n=219, P<0.001); reduction in prednisolone dose (P<0.0001); leucocyte count (n=358, P<0.0001) and C-reactive protein (n=314, P<0.0001). Patients who received > or =6 Adacolumn sessions (n=319) did better than patients who received < or =5 sessions (n=188, P=0.004) and multivariate logistic regression analysis revealed that baseline granulocyte count was the strongest predictor of clinical response to Adacolumn (P=0.0191, odds ratio 1.151). CONCLUSION This post marketing surveillance provides the largest ever efficacy and safety data on the Adacolumn therapeutic leucocytapheresis in patients with ulcerative colitis. As a non-pharmacologic treatment for patients with active ulcerative colitis most of whom were refractory to conventional drug therapy, the observed efficacy was very significant. Baseline granulocyte count was convincingly an independent predictor of clinical response.

Abstract
BACKGROUND The purpose of the study was to collect data on granulocyte-monocyte adsorptive apheresis (GMA) for the treatment of corticosteroid-dependent (SD) or corticosteroid-resistant (SR) inflammatory bowel disease (IBD) in children from 3 Nordic countries to evaluate its efficacy and safety and to assess practical issues. METHODS Retrospective data on 37 children treated with GMA were collected. In all, 22 children had ulcerative colitis (UC), 13 Crohn's disease (CD), and 2 had indeterminate colitis (IC). Their mean age was 13.2 years, range 5-17 years, and mean duration of disease was 2.4 years, range 1 month to 6 years. Indication for treatment in the UC group was SD in 11 cases, SR in 6 cases, and other reasons in 5 cases. The corresponding numbers in the CD group were SD in 8 cases, SR in 2 cases, and other reasons in 3 cases. In the IC group, 1 had SD and 1 was refractory to steroids, azathioprine, and infliximab. Efficacy was evaluated by severity indices: the Pediatric Ulcerative Colitis Activity Index (PUCAI) and the Pediatric Crohn's Disease Activity Index (PCDAI) and tapering of corticosteroids. RESULTS PUCAI and PCDAI decreased significantly in both groups after 3 months (P = 0.0007, P = 0.025). The dosage of corticosteroid was significantly reduced in the UC group by the end of GMA (P = 0.004) and this response continued after 3 months. Relapse was seen in 2 patients with UC and 3 patients with CD after 3 months follow-up. CONCLUSIONS GMA seems to be an effective and safe treatment in 81% of the SD or SR pediatric IBD patients, especially in those with UC.

Abstract
INTRODUCTION Patients who have undergone kidney transplantation and suffer from hepatitis C (HCV) cannot be treated with standard therapy (pegylated interferon combined with ribavirin) due to the risk of acute rejection. Furthermore, immunosuppressive therapy facilitates the progression of infection and chronic hepatopathies. Monocytes and macrophages are known to produce extrahepatic breeding sites that spread disease. Our aim was to reduce macrophages, granulocytes, monocytes, proinflammatory cells, and viremia levels using an extracorporeal device: Adacolumn Leukocyte Apheresis (Otzuka Electronics, Japan). METHODS The Adalcolumn filter is filled with 2-mm cellulose acetate beads immersed in sterile saline solution. These carriers absorb granulocytes and monocytes/macrophanges through their FCR receptors. Six patients affected by viral genotype 1b underwent five 1-hour treatments for 5 consecutive days. RESULTS Viremia was reduced in Patients 1, 2, 4, and 6 in association with decreased pro-inflammatory cytokine levels and a normal CD4/CD8 T-cell ratio, after 3 months. Subjects 1 and 3 showed inverted CD4(+)/CD8(+) T-cell ratios, which changed at 4-month follow-up in only patient 1. Subject 5 did not show any changes. CONCLUSIONS The treatment was safe without hemodynamic or infectious complications, suggesting that this method could be used in a greater number of patients to evaluate amelioration of increased viremia.

Abstract
Regulatory T cells (T(reg)) have an essential role in maintaining immune tolerance in the gut. The functional CD4(+) T(reg) express the transcription factor forkhead box protein 3 (FoxP3) or a CD25(high) in humans. Further, depletion of elevated granulocytes/monocytes by extracorporeal adsorption (GMA) induces immunomodulation in patients with ulcerative colitis (UC). We investigated the impact of GMA on T(reg). Thirty-one UC patients, clinical activity index (CAI) 12.1 +/- 2.97, refractory to conventional medications including intravenous corticosteroid and 13 healthy controls (HC), were included. Patients received five GMA sessions over 5 weeks. Biopsies from the rectal mucosa and blood samples at baseline and post-GMA were immunostained with anti-CD4/FoxP3 and anti-CD4/CD25 antibodies for immunohistochemistry and flow cytometry. Following GMA, 22 of 31 patients achieved remission (CAI <or= 4, P < 0.01) and their endoscopic activity index decreased from 10.6 +/- 2.32 to 4.75 +/- 1.48 (P = 0.003). The circulating CD4(+)CD25(high+) T(reg) level was low and increased markedly in responders (P < 0.02). In the nine non-responders, the baseline CD4(+)CD25(high+) T(reg) level was about 50% of the level in the responders (P < 0.03) or in the HC (P < 0.01), and all nine had to undergo colectomy. Conversely, the number of CD4(+)/FoxP3(+) mucosal T(reg) in GMA responders decreased significantly after the fifth GMA session compared with the baseline level (P < 0.05). It is believed that the CD4(+) T(reg) has an essential role in the control of immune pathology in UC patients and a net influx of these cells from the circulation into the mucosa may proceed to suppress inflammation. GMA can impact the circulating as well as the mucosal levels of T(reg).

Abstract
BACKGROUND/AIMS Cytapheresis (CAP) is a novel strategy for ulcerative colitis (UC). However, there is insufficient data on the long-term outcome of UC patients who achieve remission by CAP. This study involved patients with severe UC who refracted to intravenous (iv) corticosteroid. METHODS Forty-seven UC patients who had received CAP therapy for the first time within 1 year after UC diagnosis were followed for 36 months. One of the inclusion criteria was a clinical activity index (CAI) of >/=7 points at the end of a 2-week iv course of corticosteroid therapy. CAP therapy consisted of ten sessions over 10 weeks. RESULTS CAP induced clinical remission (CAI</=4) in 70.2% patients (33/47). The number of submissions for colectomy was higher for severe UC at entry (CAI>/=12, n=25) than for moderately severe UC at entry (7</=CAI<12, p=15; p<0.02). The cumulative rates of avoiding surgery and relapse were 54.5% and 24.2%, respectively, at 36 months in patients who responded to CAP therapy. This was similar to that of iv cyclosporine reported recently. CONCLUSIONS This study suggest that CAP is an effective therapy in patients who are refractory to conventional medications including iv corticosteroid. Increased remission rates should be expected in refractory patients with moderately severe UC.

Abstract
BACKGROUND Cytokines have validated roles in the immunopathogenesis of inflammatory bowel disease (IBD). This study was to investigate the expressions of tumor necrosis factor (TNF)-alpha, interleukin (IL)-6, IL-8, and IL-10 mRNAs in the colonic mucosa of patients with ulcerative colitis (UC) during active and quiescent UC. METHODS At colonoscopy, biopsies were taken from inflamed and non-inflamed mucosa of patients with steroid-naive UC (n = 15), non-IBD inflammatory colitis controls (ICC, n = 6), and non-colitis controls (NCC, n = 14). The presence of extensive mononuclear cells and neutrophils infiltrate in the lamina propria, cryptitis, and epithelial damage defined an inflammatory lesion in the mucosa. Quantitative cytokine mRNA expressions in biopsies were measured by real-time polymerase chain reaction (PCR). RESULTS Of 15 UC patients, 3 remitted with 5-aminosalicylate and 11 received granulocytapheresis; of these, 10 remitted. At baseline, IL-6, IL-8, TNF-alpha, and IL-10 mRNAs were high in inflamed mucosa compared with NCC (P < 0.01). In active UC, IL-6, IL-8 and IL-10 mRNAs were high compared with non-inflamed mucosa (P = 0.03, P = 0.03, P < 0.05, respectively). Both TNF-alpha mRNA (P = 0.03) and IL-6 mRNA (P = 0.04) were higher in UC compared with ICC. Even in non-inflamed mucosa, IL-8 and TNF-alpha mRNA expressions were high compared with NCC. Both IL-6 and IL-8 mRNAs decreased to normal levels after granulocytapheresis. CONCLUSIONS During active UC, all 4 cytokine mRNA levels were high; only IL-6 and IL-8 mRNAs decreased to normal levels during remission. IL-8 mRNA was high even at sites of endoscopically quiescent UC during active disease. Steroid naïve patients respond well to granulocytapheresis.

Abstract
AIM To evaluate granulocytapheresis (GCAP) in active ulcerative colitis (UC), with particular attention to the long-term effects of such treatment. METHODS We included 80 patients with UC. Activity of the disease was evaluated by clinical activity index and endoscopic index. Patients were randomly divided in two groups: Group A received a five-session (1 session/week) treatment with GCAP, Group B were treated with i.v. or i.m. methylprednisolone (MP). Concomitant therapy with oral 5-aminosalicylic acid (5-ASA) 2.4 g/day was maintained in both groups. Subjects who achieved a remission were clinically and endoscopically followed for 12 months after the end of GCAP or MP. RESULTS Remission was observed in 72.5% of those treated with GCAP versus 50% of those treated with MP. After a 12-month follow up, a sustained remission was recorded in 40% of those treated with GCAP and in 25% of those treated with MP. During the GCAP only a transient mild headache was recorded in 10% of patients, whereas side-effects were observed in 50% of those treated with MP (P < 0.05). CONCLUSION GCAP results were superior to MP for the treatment of UC, even though no statistically significant difference was observed. Side-effects in the GCAP group were significantly lower than in the MP group. This new therapeutic approach seems able to maintain the condition of remission for a longer time after a flare. In fact, the patients who had obtained a remission after a course of CGAP showed fewer relapses during the follow up compared to the patients treated with MP.

Abstract
BACKGROUND We assessed whether selective granulocyte and monocyte/macrophage adsorption apheresis maintained clinical remission in asymptomatic inflammatory bowel disease (IBD) patients at significant risk of clinical relapse. METHODS Sixty asymptomatic patients (age 18-70 years) with IBD (in clinical remission) with fecal calprotectin over 250 microg/g (which defines those at risk of clinical relapse with >80% specificity and sensitivity) were recruited for this open-label, prospective, randomized, controlled study. Twenty-nine underwent selective leukocytapheresis, undergoing 5, once weekly, out-patient sessions. Thirty-one had unchanged maintenance treatment and acted as controls. Follow-up for a clinical relapse was 6 months. The secondary outcome variable was the time to relapse. RESULTS The number of patients who remained in clinical remission at 6 months was significantly lower in controls (32.3%) than in the apheresis (72.4%) group (P = 0.0023, Fisher's exact test). The time to first relapse was significantly earlier in the control group (99 +/- 73 days) as compared with the apheresis group (161 +/- 44 days) (log-rank test; P = 0.0004). Mild and transient headache was reported by 16 of the 29 (55%) for up to 3 hours, but no serious side effects were observed. CONCLUSIONS This study represents a new approach to the treatment of IBD by targeting a group of asymptomatic patients for treatment who are at significant risk of relapse based on high fecal calprotectin concentrations. Selective leukocytapheresis significantly reduced the number of, and increased the time to, clinical relapse in these patients without serious side effects.

Abstract
In recent years, considering the role of inflammatory processes and the involvement of the immune system in ulcerative colitis, granulocytapheresis, a technique for removing circulating leukocytes and preventing their migration into the intestinal mucosa, has been proposed for the treatment of acute ulcerative colitis. Initially introduced for the treatment of patients who did not respond to conventional therapy only, this new therapy may become a useful and safe method to induce clinical remission in patients with acute disease. This article will review the clinical applications and issues concerning the use of granulocytapheresis in ulcerative colitis.

Abstract
Granulocyte and monocyte adsorption apheresis (GCAP) is a useful strategy for intractable ulcerative colitis, but its mechanisms of therapy is not fully explained. Previously, depleting activated granulocytes and monocytes (GMs) and modifying product of proinflammatory cytokines had been proposed. In addition, activated GMs are releasing anti-inflammatory cytokines, interleukin-1 receptor antagonist (IL-1ra) that may contribute to the clinical efficacy of GCAP therapy. Hence, to investigate contribution of IL-1ra as well as to confirm clinical efficacy of this therapy based on clinical activity index (CAI), we performed a multicenter study. Twenty-five of 38 (65.8%) patients achieved remission state (CAI < or = 4) and two of 38 (5.3%) revealed clinical improvement. Almost effective cases significantly decreased CAI even at 3rd session of GCAP. Plasma level of IL-1ra from outflow of the GCAP column at 30 min was significantly increased rather than inflow. Median exact elevated level of IL-1ra was 221 pg/ml and median of increasing ratio was 1.6 times. Furthermore, the responsive patients, who well released the IL-1ra at outflow more than 100 pg/ml compared with inflow, tended to show clinical effectiveness. While, the increased ratio of IL-1ra in effective cases did not differ from ineffective cases, and there were no significant relationship with improvement of CAI score. These conflict results suggest that the increase of IL-1ra at outflow is not a direct factor to the clinical improvement, but the induction of clinical improvement is accompanied by the release of IL-1ra. The IL-1ra may be involved in the multiple steps for the improvement induced by GCAP.

Abstract
Cellular apheresis is now established as a rational therapeutic procedure in certain inflammatory and autoimmune diseases, particularly in inflammatory bowel diseases, but the efficacy of this procedure can not be fully explained solely on the basis of removal of granulocytes and monocytes. It is suggested that a selective modulator increase of regulatory T cells contributes to beneficial effect of adsorptive leukocytapheresis in patients with these pathologies. Though currently applied as second-line medication, it could be considered in the future as an effective alternative to the use of immune suppressive regimens or biological agents and taken into account to establish a tailor's patient therapy in inflammatory and autoimmune conditions.

Abstract
BACKGROUND The aetiology of ulcerative colitis is inadequately understood, and drug therapy has been empirical rather than based on sound understanding of disease aetiology. This has been a major factor for refractoriness and adverse drug effects as additional complications. However, ulcerative colitis by its very nature is exacerbated and perpetuated by inflammatory cytokines, which are released by peripheral granulocytes and monocytes as well. Additionally, active ulcerative colitis is often associated with elevated peripheral granulocytes and monocytes with activation behaviour and are found in vast numbers within the colonic mucosa. Hence, from the clinicopathologic viewpoint, granulocytes and monocytes are appropriate targets for therapy in ulcerative colitis. Based on this thinking, an Adacolumn has been developed for depleting excess granulocytes and monocytes by adsorption. METHODS By colonoscopy, biopsy and histology, we investigated the impact of granulocyte and monocyte adsorption (GMA) on the mucosal level of granulocytes and monocytes in patients with active ulcerative colitis. Forty-five patients (26 steroid naïve and 19 steroid-dependent), mean age 44.7 yr, were included. Twenty patients had total colitis and 25 had left-sided colitis. Each patient was given up to 11 GMA sessions over 12 weeks. No patient received additional medications within 4 weeks (steroid) to 8 weeks (other immunosuppressants) prior to entry or during the GMA course. Colonoscopy together with biopsy was done at entry and within 2 weeks after the last GMA session. RESULTS At entry, the mean clinical activity index was 12.6; range 10-16. A total of 400 colonic biopsies were examined, which revealed massive infiltration of the colonic mucosa by granulocytes, and GMA was associated with striking reduction of granulocytes in the mucosa. At week 12, 33 of 45 patients (73.3%, P<0.01) had achieved clinical remission (the mean clinical activity index <or= 4). Colonoscopy revealed that most non-responders had deep colonic ulcers and extensive loss of the mucosal tissue. The response rate in steroid naïve subgroup was 22 of 26 patients (84.6%, P<0.005) and in steroid-dependent was 11 of 19 (57.9%, P<0.05 and P=0.02154 for steroid naïve vs. steroid-dependent). Patients who achieved remission could continue with their salicylates. On average, remission was sustained for 7.8 months in all 33 responders. CONCLUSIONS This is the first report showing a striking difference in clinical response to GMA between steroid naïve and steroid-dependent patients. Further, patients with deep colonic ulcers together with extensive loss of the mucosal tissue are not like to respond to GMA.

Abstract
BACKGROUND & AIMS Activated granulocytes and monocytes/macrophages are implicated in the pathogenesis of ulcerative colitis. Open-label studies and clinical experience in Japan and Europe have suggested that granulocyte/monocyte apheresis is safe and effective in treating ulcerative colitis. METHODS We evaluated the efficacy of granulocyte/monocyte apheresis in a randomized, double-blind, sham-controlled trial in patients with active moderate-to-severe ulcerative colitis (Mayo score 6-11) in community-based and tertiary care centers. As intervention, we used granulocyte/monocyte apheresis with the Adacolumn Apheresis System (JIMRO, Ltd, Takasaki, Japan) or sham apheresis in a 2:1 ratio for 9 weeks of treatment in a North American pivotal study (N = 168) and in a smaller, companion study of identical design conducted in Europe and Japan (N = 47). RESULTS In the pivotal study, clinical remission rates (Mayo score 0-2, with scores of 0 on rectal bleeding and 0 or 1 on endoscopic examination) were 17% and 11% for the granulocyte/monocyte apheresis (n = 112)- and sham-treatment groups, respectively (n = 56; P = .361). Clinical response (Mayo score reduction of >/=3 points from baseline) was observed in 44% and 39% of patients, respectively (P = .620). Similar changes were observed for the apheresis- and sham-treatment groups for endoscopic remission and response, and changes in Mayo and quality-of-life scores. The companion study and pooled data from both studies also yielded similar results. CONCLUSIONS In this study, granulocyte/monocyte apheresis was well tolerated but did not demonstrate efficacy for induction of clinical remission or response in patients with moderate-to-severe ulcerative colitis.

Abstract
Leukocytapheresis is a controversial nonpharmacologic treatment for IBD, in which white blood cells--the effector cells of the inflammatory process--are mechanically removed from the circulation. Current controversy centers on the uncontrolled nature of the leukocytapheresis trials performed and their use of different outcome measures in patient groups that have very variable disease activity and severity. Nonetheless, the efficacy data obtained are generally quite consistent: an excellent response (remission >80%) has been achieved in corticosteroid-naïve patients with ulcerative colitis and an average remission rate of more than 50% has been achieved in patients who have steroid-dependent or refractory ulcerative colitis. Interestingly, the largest randomized, double-blind, sham-controlled study of granulocyte-monocyte apheresis in patients with moderate to severe ulcerative colitis failed to demonstrate efficacy for the induction of clinical remission or response. Regardless, leukocytapheresis seems to be remarkably safe. The precise positioning of leukocytapheresis in the treatment of ulcerative colitis is uncertain at present and will vary according to geography and patient preference for a safe, nonpharmacologic treatment. Further efficacy studies are required to assess what the optimal number and frequency of treatments is, in addition to the need for head-to-head comparisons with established drugs.

Abstract
(Table is included in full-text article.)The development of biologicals such as infliximab to intercept TNF-alpha validates the current perception that certain cytokines are major factors in the immunopathogenesis of inflammatory bowel disease (IBD), ulcerative colitis and Crohn's disease. Furthermore, major sources of inflammatory cytokines include activated peripheral granulocytes and monocytes (GM), which in patients with IBD are elevated with increased survival time and are found in vast numbers within the inflamed intestinal mucosa. Hence, elevated GM should be appropriate targets of therapy in IBD. Accordingly, in recent years technologies such as the Adacolumn have been developed for selective depletion of elevated GM by extracorporeal adsorption (GMA). Published data show that GMA in patients with steroid-dependent or steroid-refractory IBD is associated with striking efficacy and tapering or discontinuation of steroids, whereas in steroid-naïve patients GMA spared patients from steroids. Likewise, GMA at appropriate intervals in patients at a high risk of clinical relapse significantly suppressed relapse, thus sparing the patients from the morbidity associated with active IBD. First ulcerative colitis episode, steroid naivety and short disease duration seem to be good predictors of response to GMA and on the basis of our experience, GMA seems to have an excellent safety profile.

Abstract
BACKGROUND AND AIM Several uncontrolled studies have reported on the efficacy of adsorptive depletion of peripheral blood granulocytes and monocytes/macrophages (GM) in patients with moderate or severe ulcerative colitis. This study was to compare the efficacy and safety of intensive GMA with intensive intravenous prednisolone in patients with severe ulcerative colitis. METHODS Seventy patients with clinical activity index 10-23 were randomly assigned to intensive GMA with the Adacolumn, at 2 sessions/week in the first 3 weeks and then 1 session/week for up to 11 sessions (n = 35) or intravenous prednisolone, 40-60 mg/day for 5-10 days (n = 35). No patient received immunomodulators within 8 weeks prior to entry. Clinical response based on intention to treat was assessed at weeks 2, 6 and 12. RESULTS Four patients in the prednisolone group and two patients in the GMA group discontinued in week 1. At weeks 2, 6 and 12, the remission (clinical activity index < or = 4) rates (%) in the GMA group were 17.1, 54.4, 74.3, respectively. The corresponding values in the prednisolone group were 25.7, 51.4 and 48.6. Further, at week 12, 27 patients (77%) in the GMA group and 5 patients (14%) in the prednisolone group were steroid free (P = 0.0076). In the GMA group, flushing and light-headedness were observed in 5 patients versus typical steroid side effects in 29 patients of the prednisolone group. CONCLUSIONS In this clinical response to GMA was comparable or better than prednisolone. Further, the response to GMA was slower than to intravenous prednisolone, but was more sustainable than the latter.

Abstract
BACKGROUND In human blood, two monocyte populations exist, CD14(++)CD16(-) classical monocytes and CD14(+)CD16(+) proinflammatory monocytes, which account for about 10% of total monocytes, but can expand to promote inflammatory conditions. CD14(+)CD16(+) monocytes produce large amounts of inflammatory cytokines including TNF-alpha and IL-1. Adacolumn adsorptive carriers adsorb from the blood in the column most of the monocytes/macrophages and granulocytes and this has been associated with clinical efficacy in patients with active inflammatory bowel disease (IBD). This study was to investigate the CD14(+)CD16(+) monocyte profile in patients with IBD and the impact of Adacolumn on this proinflammatory phenotype. METHODS A total of 58 patients with ulcerative colitis (UC, N = 37) or Crohn's disease (CD, N = 21) together with 11 healthy controls were included in this study. Peripheral blood CD14(+)CD16(+) monocytes were determined by three-color immunofluorescence and flow cytometry. RESULTS The percentage of CD14(+)CD16(+) monocytes in patients with active CD was significantly (P= 0.0089) higher than the level in the control group, in patients with quiescent CD (P= 0.0419) or quiescent UC (P= 0.0063). Further, the percentage of CD14(+)CD16(+) monocytes in patients with active UC who were on prednisolone (PSL) was less than the level in those not on PSL (P < 0.0001), thus PSL might have a suppressive effect on CD14(+)CD16(+) monocytes. Patients with active IBD were each given up to 10 Adacolumn granulocye/monocyte adsorption (GMA) sessions over an 8-wk period. The percentage of CD14(+)CD16(+) monocytes decreased dramatically (P= 0.0077 in UC and P= 0.0117 in CD) compared with entry levels. CONCLUSIONS A significant reduction in peripheral CD14(+)CD16(+) monocytes by GMA should mitigate the inflammatory drive and contribute to the clinical efficacy of this procedure. Reduction of CD14(+)CD16(+) monocytes by corticosteroids was also seen. Hence, corticosteroids should enhance the efficacy of GMA. This is the first report on CD14(+)CD16(+) monocytes being decreased by Adacolumn GMA in patients with IBD.

Abstract
The objective of this study is to evaluate the cellular mechanism underlying filtration leukocytapheresis (LCAP) therapy for the treatment of rheumatoid arthritis (RA). Thirteen patients with refractory RA each underwent three sessions of LCAP. Before (pre-) and after (post-) the completion of the first LCAP session, peripheral blood was sampled and analyzed for neutrophil surface markers using flow cytometry. The surface antigens of peripheral blood mononuclear cells (PBMCs) and neutrophils obtained at pre- and post-LCAP were then analyzed using a fluorescence-activated cell sorter. The American College of Rheumatology's criterion of a 20% improvement was achieved in six patients, but not in the other seven patients, after LCAP therapy. The post-LCAP number of blood band form neutrophils with a bone marrow phenotype (CD49d(dim+), low density) was higher among the responders than among the nonresponders, suggesting an association between the clinical response and the recruitment of bone-marrow-derived neutrophils. After the nonspecific absorption of WBCs during a 1-h Cellsorba procedure, the number of PBMCs was consistently decreased, although the number of neutrophils that were affected by removal plus recruitment varied in a manner that was independent of efficacy. In contrast, the emergence of immature neutrophils in the peripheral blood was characteristic of the effective therapies. These cells were found after the 1st session of responders and also found following sessions of LCAPs. Immature neutrophils, which may be recruited from the bone marrow in the peripheral blood after the first session of LCAP, can predict the clinical efficacy of subsequent LCAP sessions.

Abstract
Granulocyte and monocyte adsorption apheresis (GCAP) has recently shown remarkable effects on ulcerative colitis, which is characterized by inflammation and neutrophil infiltration. Pustular psoriasis often shows histological findings of neutrophilic pustules in the epidermis, and in Japan is usually treated with etretinate or immunosuppressive agents. However, there are some resistant cases to these therapies. We performed GCAP on one patient with generalized pustular psoriasis (patient 1) and on one patient with acrodermatitis continua, a subtype of pustular psoriasis limited to acral lesions (patient 2). Patient 1, a 44-year-old woman suffering from alcoholic liver cirrhosis and osteoporosis as a result of the liver cirrhosis, received two GCAP sessions because cyclosporine was ineffective. Patient 2, a 66-year-old man with hypertension who had suffered from a brain infarction 4 years before, had five GCAP sessions because etretinate was ineffective. GCAP remarkably improved the skin lesions in both patients. No adverse effects were observed either during or after treatment. From these findings, GCAP could be an effective therapy for refractory cases of pustular psoriasis.

Abstract
Ulcerative colitis (UC) is a chronic inflammatory bowel disorder characterized by exacerbations and remissions. Some UC patients remain refractory to conventional medical treatment while, in others, the effectiveness of drugs is limited by side-effects. Recently, cyclosporine and leukocyte removal therapy have been used for refractory UC patients. To predict the efficacy of these therapies is important for appropriate selection of treatment options and for preparation for colectomy. Endoscopy is the cornerstone for diagnosis and evaluation of UC. Endoscopic parameters in patients with severe or refractory UC may predict a clinical response to therapies, such as cyclosporine or leukocyte removal therapy. As for the patients with quiescent UC, relapse of UC is difficult to predict by routine colonoscopy. Even when routine colonoscopy suggests remission and a normal mucosal appearance, microscopic abnormalities may persist and relapse may occur later. To more accurately identify disease activity and to predict exacerbations in UC patients with clinically inactive disease is important for deciding whether medical treatment should be maintained. Magnifying colonoscopy is useful for the evaluation of disease activity and for predicting relapse in patients with UC.

Abstract
AIM: To investigate if the clinical efficacy of granulocytes and monocytes by adsorption (GMA) is associated with an increased frequency of peripheral regulatory T cells (Tregs), as these cells have proven to be successful in suppressing inflammatory bowel disease (IBD) in animal models.
METHODS: We report four cases of corticosteroid-dependent ulcerative colitis (UC) and two Crohn’s disease (CD) cases with severe cutaneous lesions who received GMA therapy. The frequency of CD4+ CD25high (Tregs) in peripheral blood was analyzed by flow cytometry and the expression of FoxP3 and TGF beta in purified CD4+ T cells was determined by real time PCR prior to and one month after the last apheresis session, and at the time of endoscopic and clinical assessing.
RESULTS: Increased expression of Fox P3 mRNA was found in all five patients who responded to cytapheresis with remission of clinical symptoms, mucosal inflammation and cutaneous lesions, and an increased frequency of circulating Tregs was found in four patients. These changes were not observed in the patient with UC who did no respond to GMA. Variations in TGF-β (mRNA) did not parallel that of FoxP3 mRNA.
CONCLUSION: The clinical efficacy of GMA on IBD and related extra intestinal manifestations was associated with an expansion of circulating CD4+ CD25+ Tregs and higher expression of FoxP3 in CD4+ T cells. Accordingly, an elevated CD4+ CD25+ FoxP3 may be a valuable index of remission in patients with IBD and other chronic relapsing-remitting inflammatory conditions during treatment with GMA.

Abstract
Granulocytapheresis (GCAP) therapy is a newly developed therapeutic modality for inflammatory bowel diseases such as ulcerative colitis and Crohn's disease. Pyoderma gangrenosum (PG) is a chronic inflammatory skin disease characterized by the appearance of erythematous macules and plaques with pustules or nodules that rapidly progress to ragged, undermined multiple ulcers. We attempted GCAP therapy in a patient with PG resistant to prednisolone and various other immunosuppressants. GCAP therapy was initiated at three- to four-day intervals and a good response from all skin lesions, with eventual total epithelialization, was observed after 10 sessions of this therapy. Furthermore, circulating levels of inflammatory cytokines such as interleukin-8 (IL-8) and granulocyte colony stimulating factor (G-CSF) also decreased after the GCAP therapy. Our results suggest that GCAP is a safe and useful tool for the treatment of intractable PG, and that IL-8 and G-CSF are likely to be involved in the pathogenesis of PG.

Abstract
SUMMARY: Although inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn's disease (CD), is a chronic recurrent disease with unknown etiology. Recent immunological studies suggest close relation to autoimmune status featured by antibodies against colonic epithelial cells. For patients with IBD, 5-aminosalycilates are often used in case of mild disease, and corticosteroids are standard therapy for moderate-to-severe disease. However, we often encounter patients who are resistant to or dependent of conventional therapy, which are likely to lead to future problems in quality of life due to adverse effects of drugs used, especially corticosteroids. Extracorporeal leukocyte removal therapy (cytapheresis) is one of the adjunctive therapies for IBD patients refractory to steroids. By removing circulating activated leukocytes, especially granulocytes and lymphocytes, impaired immune response is suppressed. In the present article recently published studies are reviewed in order to reflect the current state of the art in the use of cytapheresis for treating IBD, especially UC and CD. Although there are only few randomized controlled trials, clinical experience so far suggests that cytapheresis has superior efficiency than conventional therapies in steroid-resistant moderate-to-severe UC. Moreover, cytapheresis features its safety characteristic compared with other conventional medications for severe UC, cytapheresis is regarded as safe treatment regimen.

Abstract
BACKGROUND To clarify which types of cells produce interferon-gamma-inducible protein 10 (IP-10) and whether IP-10 is associated with the development of ulcerative colitis (UC), we investigated IP-10 production in UC patients. METHODS Serum IP-10 levels were measured using enzyme-linked immunosorbent assay in 29 patients with active and 21 with inactive UC and in 20 controls. The production of IP-10 by granulocytes and monocytes adsorbed to G-1 beads was examined. In 21 active UC patients treated with granulocyte and monocyte/macrophage adsorptive apheresis (GMA), serum IP-10 levels were measured before and after treatment. IP-10-positive cells in UC mucosa were also examined immunohistochemically using tissues obtained by surgical resection and colonoscopic biopsies. RESULTS Serum IP-10 levels in active UC patients were significantly higher than those in inactive patients, although even in the latter the levels were increased compared with those in controls. IP-10 production by granulocytes and monocytes in active UC patients was significantly higher than that in controls. Furthermore, the number of IP-10-positive cells was elevated in the colonic mucosa of patients with active UC, and one of the main subpopulations of IP-10-positive cells was granulocytes. Serum IP-10 levels decreased following GMA treatment in responders, but not in nonresponders. Interestingly, serum IP-10 levels before GMA were higher in responders than in nonresponders. In parallel with the serum levels, IP-10-positive cells also decreased following GMA treatment. CONCLUSIONS Serum IP-10 levels reflected UC disease activity, and the source of IP-10 was granulocytes and monocytes. Furthermore, serum IP-10 levels may be a marker for the responsiveness of patients to GMA treatment.

Abstract
Pyoderma gangrenosum presents with chronic skin ulcers and is histologically characterized by neutrophil infiltration throughout the dermis. It is also occasionally associated with ulcerative colitis, a type of inflammatory bowel disease, against which granulocyte and monocyte adsorption apheresis (GCAP) has recently shown remarkable efficacy. We performed GCAP on three refractory cases of pyoderma gangrenosum with painful bilateral leg ulcers and hereby report the results obtained. Patient 1 was a 43-year-old woman with a four-year history of recurrent painful skin ulcers treated with prednisolone and cyclosporine. Patient 2 was a 29-year-old woman who had been suffering from pyoderma gangrenosum with severe pain for two weeks, associated with an 11-year history of ulcerative colitis treated with prednisolone and salazosulfapyridine. Patient 3 was a 63-year-old man with a three-year history of recurrent ulcers with pain, suffering from rheumatoid arthritis treated with prednisolone and cyclophosphamide. The sizes of the lesions were reduced in all three patients following a weekly GCAP treatment for 10 or 11 consecutive weeks, and the re-epithelialization of ulcers were additionally observed in two patients. The pain disappeared dramatically in all three patients following two sessions of GCAP therapy. No adverse effects were observed for up to at least eight months after treatment. We therefore considered GCAP as one effective alternative to currently existing therapies, with regards to refractory cases of pyoderma gangrenosum.

Abstract
The etiology of inflammatory bowel disease (IBD) is not completely understood, thus current therapies have been empirical and directed at treating symptoms rather than addressing the cause. In IBD, the overexpression of proinflammatory cytokines, such as tumor necrosis factor-alpha, interleukin-1beta, interleukin-6, leads to a persistent intestinal inflammatory response that damages the intestinal mucosa. Recent advances in pharmacologic therapies that target specific cytokines, chemokines, and adhesion molecules have proved successful in alleviating symptoms for some patients. There are 2 selective adsorption apheresis devices that remove leukocytes from whole blood, which are currently available in Japan and Europe-the Cellsorba leukocytapheresis column and the Adacolumn adsorptive extracorporeal granulocyte/monocyte apheresis device. The purported mechanisms of action of these devices have been extensively reviewed and are believed to exert an immunomodulatory and/or anti-inflammatory effect on patients with systemic inflammatory disease. The clinical trials presented here indicate that selective leukocyte apheresis effectively removes activated granulocytes and monocytes/macrophages from peripheral blood while maintaining an excellent safety profile. Despite these findings, large controlled trials of selective leukocyte apheresis in the treatment of IBD are needed to determine the true efficacy of this approach.
