Abstract
BACKGROUND Real-world data on tofacitinib (TOF) covering a period of more than 1 year for a sufficient number of Asian patients with ulcerative colitis (UC) are scarce. AIM To investigate the long-term efficacy and safety of TOF treatment for UC, including clinical issues. METHODS We performed a retrospective single-center observational analysis of 111 UC patients administered TOF at Hyogo Medical University as a tertiary inflammatory bowel disease center. All consecutive UC patients who received TOF between May 2018 and February 2020 were enrolled. Patients were followed up until August 2020. The primary outcome was the clinical response rate at week 8. Secondary outcomes included clinical remission at week 8, cumulative persistence rate of TOF administration, colectomy-free survival, relapse after tapering of TOF and predictors of clinical response at week 8 and week 48. RESULTS The clinical response and remission rates were 66.3% and 50.5% at week 8, and 47.1% and 43.5% at week 48, respectively. The overall cumulative clinical remission rate was 61.7% at week 48 and history of anti-tumor necrosis factor-alpha (TNF-α) agents use had no influence (P = 0.25). The cumulative TOF persistence rate at week 48 was significantly lower in patients without clinical remission than in those with remission at week 8 (30.9% vs 88.1%; P < 0.001). Baseline partial Mayo Score was significantly lower in responders vs non-responders at week 8 (odds ratio: 0.61, 95% confidence interval: 0.45-0.82, P = 0.001). Relapse occurred in 45.7% of patients after TOF tapering, and 85.7% of patients responded within 4 wk after re-increase. All 6 patients with herpes zoster (HZ) developed the infection after achieving remission by TOF. CONCLUSION TOF was more effective in UC patients with mild activity at baseline and its efficacy was not affected by previous treatment with anti-TNF-α agents. Most relapsed patients responded again after re-increase of TOF and nearly half relapsed after tapering off TOF. Special attention is needed for tapering and HZ.

Abstract
BACKGROUND Beyond systematic reviews and meta-analyses, there have been no direct studies of serological response to COVID-19 in patients with inflammatory bowel disease (IBD) across continents. In particular, there has been limited data from Asia, with no data reported from India. The ICARUS-IBD (International study of COVID-19 Antibody Response Under Sustained immunosuppression in IBD) consortium assessed serological response to SARS-CoV-2 in patients with IBD in North America, Europe, and Asia. METHODS The ICARUS-IBD study is a multicenter observational cohort study spanning sites in 7 countries. We report seroprevalence data from 2303 patients with IBD before COVID-19 vaccination between May 2020 and November 2021. SARS-CoV-2 anti-spike and anti-nucleocapsid antibodies were analyzed. RESULTS The highest and lowest SARS-CoV-2 anti-spike seropositivity rates were found in Asia (81.2% in Chandigarh and 57.9% in Delhi, India; and 0% in Hong Kong). By multivariable analysis, country (India: odds ratio [OR], 18.01; 95% confidence interval [CI], 12.03-26.95; P < .0001; United Kingdom: OR, 2.43; 95% CI, 1.58-3.72; P < .0001; United States: OR, 2.21; 95% CI, 1.27-3.85; P = .005), male sex (OR, 1.46; 95% CI, 1.07-1.99; P = .016), and diabetes (OR, 2.37; 95% CI, 1.04-5.46; P = .039) conferred higher seropositivity rates. Biological therapies associated with lower seroprevalence (OR, 0.22; 95% CI, 0.15-0.33; P < .0001). Multiple linear regression showed associations between anti-spike and anti-nucleocapsid titers with medications (P < .0001) but not with country (P = .3841). CONCLUSIONS While the effects of medications on anti-SARS-CoV-2 antibody titers in patients with IBD were consistent across sites, geographical location conferred the highest risk of susceptibility to serologically detectable SARS-CoV-2 infection. Over half of IBD patients in India were seropositive prior to vaccination. These insights can help to inform shielding advice, therapeutic choices, and vaccine strategies in IBD patients for COVID-19 and future viral challenges.

Abstract
BACKGROUND & AIM The short-term effects of teduglutide (TED) for short bowel syndrome with chronic intestinal failure (SBS-IF) in patients with Crohn's disease (CD) remain unknown. The aim of this study was to investigate the effects of TED in patients with CD on home parenteral support (PS) for SBS-IF. METHODS We retrospectively investigated the medical records of patients with CD associated with SBS-IF who initiated TED between 2020 and 2021. The primary outcomes were the change in PS volume and proportion of patients with a reduction of PS volume by ≥ 20% at week 8. Secondary outcomes were the change in PS volume in patients with CD without/with colon in continuity and adverse events during the observation period. RESULTS Eighteen patients with CD who underwent home PS for SBS-IF were included in this study. Two patients were excluded owing to intolerable abdominal pain or vomiting within 8 weeks (11%). Sixteen patients continued TED throughout the observation period. The median PS duration was 10.5 years. The median observation period was 22 weeks after starting TED. TED significantly reduced the PS volume from 15,825.0 mL/week to 10,700.0 mL/week (p = 0.0038), and the PS volume decreased by ≥ 20% in 7 patients (43.8%) at week 8. The PS volume was significantly reduced at week 4 (p = 0.0078) in 11 patients without colon in continuity but not in 5 patients with colon in continuity. Two patients successfully stopped home PS. No serious adverse events occurred. CONCLUSIONS TED administration significantly reduced PS volume at week 8 in patients with CD associated with SBS-IF, and at week 4 in patients without colon in continuity.

Abstract
INTRODUCTION Ustekinumab (UST) is an antibody to the p40 subunit of interleukins 12 and 23 in Crohn's disease (CD) patients. Few reports are available on CD in the Asian scenario. OBJECTIVE We evaluated UST's efficacy in inducing remission and its maintenance in Japanese CD patients. METHODS This retrospective study was conducted in UST-treated CD patients at our center. The primary endpoint was the clinical remission rate at week 8; the major secondary endpoints were the clinical remission rate at week 24 or 48, change in CD activity index (CDAI) and biomarkers, endoscopic efficacy, and cumulative remission maintenance rate. RESULTS The clinical remission rates at weeks 8, 24, and 48 were 44.4, 66.7, and 50.0%, respectively. Delayed response was shown by 22.2% of the patients; they achieved remission by week 24. The baseline CDAI was significantly lower in the remission group than in the nonremission group at week 8 (95% CI 0.89-0.99; p = 0.03). The cumulative remission maintenance rates at 6 and 12 months were 82.4 and 49.8%, respectively. Loss of response (LOR) was noted in 22.2% of the patients within 1 year. The endoscopic response and mucosal healing rate were 52.6 and 5.3%, respectively. Rapid improvements in serum albumin levels were observed at weeks 8 (p = 0.06), 24 (p < 0.01), and 48 (p = 0.01) from the baseline in active cases at baseline. CONCLUSIONS UST is effective for remission induction and maintenance, especially in those with lower CD activity, however, may result in delayed response or LOR.

Abstract
Background/Aims Recent genome-wide analyses have provided strong evidence concerning adverse events caused by thiopurine drugs such as azathioprine (AZA) and 6-mercaptopurine. The strong associations identified between NUDT15 p.Arg139Cys and thiopurine-induced leukopenia and severe hair loss have been studied and confirmed over the last 2 years. However, other coding variants, including NUDT15 p.Val18_Val19insGlyVal, NUDT15 p.Val18Ile, and FTO p.Ala134Thr, and a noncoding variation in RUNX1 (rs2834826) remain to be examined in detail in this respect. Therefore, we investigated the correlation between these adverse events and the 5 recently identified variants mentioned above among Japanese patients with inflammatory bowel diseases (IBD). Methods One hundred sixty thiopurine-treated patients with IBD were enrolled. Genotyping was performed using TaqMan SNP Genotyping Assays or Sanger sequencing. Results None of the 5 variants were associated with gastrointestinal intolerance to AZA. However, NUDT15 p.Arg139Cys was significantly associated with the interval between initiation and discontinuation of AZA among patients with gastrointestinal intolerance. This variant was strongly associated with early (<8 weeks) and late (≥8 weeks) leukopenia and severe hair loss. Moreover, it correlated with the interval between initiation of thiopurine therapy and leukopenia occurrence, and average thiopurine dose. NUDT15 p.Val18_Val19insGlyVal, NUDT15 p.Val18Ile, FTO p.Ala134Thr, and RUNX1 rs2834826 exhibited no significant relationship with the adverse events examined. Conclusions Of the 5 variants investigated, NUDT15 p.Arg139Cys had the strongest impact on thiopurine-induced leukopenia and severe hair loss; therefore, its genotyping should be prioritized over that of other variants in efforts to predict these adverse events in Japanese patients with IBD.

Abstract
In the inflammatory bowel disease (IBD) therapeutic settings, leukocytapheresis (LCAP), and Adsorptive Granulocyte/Monocyte Apheresis (GMA) are currently the two major cytapheresis (CAP) strategies approved and are applied to treat patients with IBD, which has become refractory to conventional pharmacological intervention. Further, based on our recently concluded prospective multi-centre studies, we can now report on the therapeutic efficacy, safety and demographic factors, which identify ulcerative colitis (UC) patients as responders, or otherwise as non-responders to CAP. Further, in Crohn's disease (CD) patients, hitherto studies have not identified CAP-responder features. Regarding the maintenance of remission after GMA-induced remission, shorter duration and corticosteroid responder background were significant factors for maintenance of remission, while corticosteroid dependent UC was associating with early relapse. Considering LCAP, intensive therapy was more effective in UC patients with high baseline clinical activity score and a higher biomarker than weekly LCAP. Additionally, we have started assessing the efficacy of CAP in patients with IBD refractory to anti- tumour necrosis factor (TNF)-a biologics, and hope our work may lead to better management of drug refractory IBD. In conclusion, demographic features, which identify a patient as a potential responder to CAP or any given therapeutic intervention should guide to stop futile use of medical resources and shorten morbidity time for non- responder patients who may opt for an alternative therapy.

Abstract
BACKGROUND & AIMS To improve the clinical course of ulcerative colitis (UC), more accurate serum diagnostic and assessment methods are required. We used serum metabolomics to develop diagnostic and assessment methods for UC. METHODS Sera from UC patients, Crohn's disease (CD) patients, and healthy volunteers (HV) were collected at multiple institutions. The UC and HV were randomly allocated to the training or validation set, and their serum metabolites were analyzed by gas chromatography mass spectrometry (GC/MS). Using the training set, diagnostic and assessment models for UC were established by multiple logistic regression analysis. Then, the models were assessed using the validation set. Additionally, to establish a diagnostic model for discriminating UC from CD, the CD patients' data were used. RESULTS The diagnostic model for discriminating UC from HV demonstrated an AUC of 0.988, 93.33% sensitivity, and 95.00% specificity in the training set and 95.00% sensitivity and 98.33% specificity in the validation set. Another model for discriminating UC from CD exhibited an AUC of 0.965, 85.00% sensitivity, and 97.44% specificity in the training set and 83.33% sensitivity in the validation set. The model for assessing UC showed an AUC of 0.967, 84.62% sensitivity, and 88.23% specificity in the training set and 84.62% sensitivity, 91.18% specificity, and a significant correlation with the clinical activity index (rs=0.7371, P<0.0001) in the validation set. CONCLUSIONS Our models demonstrated high performance and might lead to the development of a novel treatment selection method based on UC condition.

Abstract
BACKGROUND AIMS In patients with inflammatory bowel disease infected with hepatitis B virus (HBV), immunosuppressive therapy required to suppress active inflammatory bowel disease may promote HBV reactivation. METHODS A 27-year-old corticosteroid-naive woman with Crohn's disease (CD) activity index of 249.8 complicated by HBV infection was offered Entecavir to control HBV reactivation during immunosuppressive therapy for CD. The patient refused Entecavir, fearing that it might adversely affect her pregnancy outcome. Instead, we applied intensive granulocyte/monocyte adsorptive apheresis (GMA) at two sessions per week to deplete inflammatory cytokine-producing leucocytes as an immunosuppressive therapy in this case. RESULTS GMA induced stable remission (CD activity index, I 105) and endoscopic improvement without HBV reactivation or safety concern. Furthermore, CD remission was paralleled by suppression of tumor necrosis factor and interleukin as measured in serum samples. CONCLUSIONS Immunosuppressive therapy required to treat an active CD potentially can promote HBV reactivation and worsen liver function. In this study involving a CD case complicated by chronic HBV infection, intensive GMA as a non-pharmacologic treatment intervention was associated with clinical remission and endoscopic improvement without HBV reactivation. Furthermore, GMA was well-tolerated and was without any safety concern. However, suppression of tumor necrosis and interleukin-6by GMA in this clinical setting is potentially very interesting.

Abstract
AIM: To clarify the usefulness of postsurgical capsule endoscopy (CE) in the diagnosis of recurrent small bowel lesions of Crohn’s disease (CD).
METHODS: This prospective study included 19 patients who underwent ileocolectomy or partial ileal resection for CD. CE was performed 2-3 wk after surgery to check for the presence/absence and severity of lesions remaining in the small bowel, and for any recurrence at the anastomosed area. CE was repeated 6-8 mo after surgery and the findings were compared with those obtained shortly after surgery. The Lewis score (LS) was used to evaluate any inflammatory changes of the small bowel.
RESULTS: One patient was excluded from analysis because of insufficient endoscopy data at the initial CE. The total LS shortly after surgery was 428.3 on average (median, 174; range, 8-4264), and was ≥ 135 (active stage) in 78% (14 of 18) of the patients. When the remaining unresected small bowel was divided into 3 equal portions according to the transition time (proximal, middle, and distal tertiles), the mean LS was 286.6, 83.0, and 146.7, respectively, without any significant difference. Ulcerous lesions in the anastomosed area were observed in 83% of all patients. In 38% of the 13 patients who could undergo CE again after 6-8 mo, the total LS was higher by ≥ 100 than that recorded shortly after surgery, thus indicating a diagnosis of endoscopic progressive recurrence.
CONCLUSION: Our pilot study suggests that CE can be used to objectively evaluate the postoperative recurrence of small bowel lesions after surgery for CD.

Abstract
OBJECTIVE This study aimed to assess the efficacy and tolerability of leukocytapheresis (LCAP) and to investigate predictive factors for mucosal healing and a sustained clinical response in steroid-free and steroid-refractory patients with ulcerative colitis (UC). MATERIAL AND METHODS Thirty-one steroid-free or steroid-refractory patients with active UC were enrolled. Five or ten consecutive sessions of LCAP were performed in each patient. The efficacy and tolerability was then evaluated at weeks 3 and 6. Endoscopic examination was performed at week 6 to evaluate the mucosal healing, and the sustained cumulative response rate was evaluated at 12 months. RESULTS At week 6, the mean Mayo clinical activity score had decreased significantly from 8.0 to 4.6 in the steroid-free patients and from 8.3 to 3.9 in the steroid-refractory patients. Rachmilewitz's endoscopic index had also decreased significantly from 9.1 to 6.1 in the steroid-free patients and from 10.0 to 5.7 in the steroid-refractory patients. Forty-seven percent of the steroid-free patients and 33% of the steroid-refractory patients achieved mucosal healing. The peripheral platelet counts had decreased significantly at weeks 3 and 6 in the mucosal healing group, compared with the non-mucosal healing group. The patients with a more than 15% platelet reduction had a significantly higher cumulative response rate, compared with the patients without a platelet reduction (p = 0.015). CONCLUSIONS LCAP is beneficial for the induction of mucosal healing in steroid-free and steroid-refractory patients with UC. The degree of platelet reduction during LCAP might be a predictive marker for mucosal healing and a sustained clinical response.

Abstract
BACKGROUND Adsorptive granulocyte and monocyte apheresis (GMA) with an Adacolumn in patients with ulcerative colitis (UC) has been applied as a non-pharmacological treatment strategy, but the efficacy has been encouraging as well as discouraging, depending on patients' demography at entry. In this study, we looked for predictive factors for clinical response to GMA in patients with UC. METHODS In a retrospective setting, 43 outpatients who had been treated with GMA for active UC were evaluated. Patients were divided into remission group and non-remission group based on Lichtiger's clinical activity index (CAI) before and after 10, once a week GMA sessions. The efficacy was analysed in relation to patients' demographic variables. To determine predictive factors that closely related to the response to GMA, receiver operating characteristic (ROC) curve, and multiple logistic regression analyses were applied. RESULTS After 10 GMA sessions, the overall clinical remission rate (CAI < 4) was 53.5%. Multiple logistic regression and ROC analyses showed that the interval between relapse and the first GMA session was a significant and independent predictive factor for clinical response to GMA (P = 0.016); the clinical response was better in patients who received GMA immediately after a relapse and vice versa. Likewise, univariate analyses showed that, the duration of UC (P = 0.036) and the cumulative prednisolone (PSL) dose (P = 0.006) before the first GMA session were significantly greater in the GMA non-responder group as compared with the responder group. Additionally, a lower white blood cell (WBC) count at first GMA session was related to clinical response to GMA (P = 0.032). CONCLUSIONS In this study, patients with a short duration of UC and low cumulative PSL dose seemed to respond well to GMA. However, we found that the best responders were patients who received GMA immediately after a clinical relapse. Additionally, GMA was effective in patients with low WBC count at the first GMA session. The findings of this study should spare medical cost and reduce morbidity time for many patients, relevant for decision making in clinical settings.

Abstract
BACKGROUND AND AIM Topical mesalamine or corticosteroid has shown efficacy in patients with ulcerative proctitis, but patients often become refractory to these interventions. Xilei San is a herbal preparation with evidence of anti-inflammatory effects. We evaluated the efficacy of topical Xilei San in ulcerative proctitis patients. METHODS In a double blind setting, 30 patients with intractable ulcerative proctitis despite ≥ 4 weeks of topical mesalamine or corticosteroid were randomly assigned to True (n = 15) and placebo (n = 15). Patients in True received suppository Xilei San (0.1 g/dose per day of Xilei San), the other 15 received placebo suppository. The initial efficacy was evaluated on day 14. Primary endpoint of the trial was avoiding relapse during 180 days, relapse meant recurrence of active disease. Riley's index was applied for endoscopic and histological evaluations, while patients' quality of life was evaluated by an inflammatory bowel disease questionnaire. RESULTS On day 14, the number of patients who achieved remission, clinical activity index ≤ 4 in True was significantly higher versus placebo (P < 0.04). Likewise, at day 180, an 81.8% of patients in True were without relapse versus 16.7% in placebo (P < 0.001). Further, significant endoscopic (P < 0.01), histological (P < 0.02) and inflammatory bowel disease questionnaire (P < 0.04) improvements were observed in True, but not in placebo. CONCLUSIONS This is the first controlled investigation showing significant clinical and endoscopic efficacy for Xilei San in patients with intractable ulcerative proctitis. Topical Xilei San was well tolerated, and was without safety concerns.

Abstract
BACKGROUND Infliximab (IFX) is effective for remission induction and maintenance of Crohn's disease (CD). This trial assessed the efficacy of scheduled maintenance IFX monotherapy to prevent postoperative CD recurrence. METHODS Thirty-one CD patients who had ileocolic resection within the past 4 weeks were randomly assigned to scheduled IFX at 5 mg/kg intravenously every 8 weeks for 36 months (n = 15) or without IFX (control, n = 16). All patients were treated without immunomodulator or corticosteroid following surgery. The primary and secondary endpoints were remission rates at 12 and 36 months, defined as CD Activity Index (CDAI) ≤150, an International Organization for the Study of Inflammatory Bowel Disease (IOIBD) score <2, and C-reactive protein (CRP) <0.3 mg/dL. Additionally, endoscopic recurrences at 12 and 36 months were evaluated. RESULTS At 12 and 36 months, 100%, and 93.3% of patients in the IFX group were in remission (IOIBD <2), respectively vs. 68.8% and 56.3% in the control arm (P < 0.03). Similarly, 86.7% and 86.7% of patients in the IFX group maintained serological remission (CRP <0.3 mg/dL) vs. 37.5% and 37.5% in the control arm (P < 0.02). Further, the IFX group achieved higher endoscopic remission at 12 months, 78.6% vs. 18.8% (P = 0.004). However, in the Kaplan-Meier survival analysis the CDAI scores between the two arms were not significantly different either at 12 or at 36 months. No adverse event (AE) was observed. CONCLUSIONS An early intervention with IFX monotherapy should prevent clinical, serological, and endoscopic CD recurrence following ileocolic resection. Thiopurine naivety and eliminating the initial loading dose of IFX might minimize serious AEs.

Abstract
The CD4+CD25High T-cell phenotype has an essential immunoregulatory role, while the CD4+CD28null T-cell reflects immune pathology. We investigated the profiles of the CD4+CD25High and the CD4+CD28null T-cell phenotypes in patients with ulcerative colitis (UC) during active and quiescent phases as well as following colectomy. Fifty-nine UC patients, 34 active (UCa) and 25 quiescent (UCq) together with 19 healthy controls (HC) were included. Ten of 34 UCa patients underwent colectomy due to unremitting UC (UCo). Immunohistochemical phenotypic of the peripheral blood lymphocytes bearing CD4, CD25 or CD28 was done for analyzes by a multiparameter fluorescence activated cell sorting technique. The expression of the CD4+CD25High phenotype was higher in UCq (P<0.01) or UCo (P<0.01) group vs UCa group. Further, the expression of the CD4+CD28null phenotype in UCa or UCo group was higher than in the HC group (P<0.05). However, the expression of the CD4+CD28null phenotype up to 12 months after colectomy was not significantly different from the levels in the same patients during acute phase. Our impression is that a high CD4+CD25High T-cell reflects alleviation of inflammation, while the expression of the CD4+CD28null T-cell phenotype is an etiologic feature in UC patients, and is maintained after removing the affected colon.

Abstract
BACKGROUND/AIMS Infliximab (IFX), an antibody to tumor necrosis factor, (TNF)-α has efficacy in treating Crohn's disease (CD). However, knowledge of the potential effects of IFX on patients' immune profiles is lacking. The purpose of this study was to reveal the immunological effects of IFX. METHODS Twenty-two patients with a CD activity index (CDAI) of 194.2±92.9 and an average duration of disease of 3.26 months and 21 healthy controls were included. Patients were to have their first IFX remission induction therapy with 3 infusions (5 mg/kg) at weeks 0, 2, and 6. Oral 5-aminosalicylic acid was the only ongoing medication in the patient population. Blood samples at baseline, 12 hours after the first infusion and at week 14 were labeled with anti-CD4/CD25 antibodies for immunohistochemical measurement of regulatory T-cells (Treg). Serum cytokines and chemokines were measured by suspension array and ELISA. RESULTS CDAI significantly decreased prior to the second IFX infusion (p<0.001). Clinical remission rates were 77.3% and 91% by the second and third infusions, respectively. At baseline, interleukin (IL)-6 (p<0.03), IL-8 (p<0.03), IL-10 (p=0.050), IL-13 (p<0.01), transforming growth factor-β1 (p<0.01), and 'regulated on activation, normal T cell expressed and secreted' (RANTES) (p<0.01) were elevated in patients. After the initial IFX infusion, TNF-α (p<0.04), IL-6 (p<0.03), interferon (IFN)-γ (p<0.04), IFN-γ-inducible protein-10 (p<0.01), monocyte chemoattractant protein-1 (p<0.01), macrophage inflammatory protein-1β (p<0.01), and RANTES (p<0.01) were decreased. IFX infusion was associated with an increase in Treg (p<0.01) and a decrease in the Th1 (IFN-γ)/Th2 (IL-4) ratio (p<0.03). CONCLUSIONS IFX use was associated with restoration of the Th1/Th2 balance after a single infusion and seemed to promote induction of naïve Th0 lymphocytes to Treg. This knowledge should have clinical relevance.

Abstract
BACKGROUND This is the first report on a case of Crohn's disease (CD), who was successfully maintained with a combination of infliximab (IFX) and selective depletion of granulocytes/monocytes by adsorption (GMA). CASE A 33-year-old female with CD activity index (CDAI) 294.2 responded to iv IFX (5mg/kg) administered at weeks 0, 2, and 6 in combination with 3000 mg/day oral 5-aminosalicylic acid (5-ASA; CDAI = 118). Then IFX at 8 week intervals was given as maintenance therapy. Two weeks before the 5th scheduled IFX, the patient worsened with an increase in stool frequency and a rise in CDAI. GMA was administered at weeks 5, 6, and 7 after her 6th iv IFX. Her CDAI decreased from 166.2 to 126.3 and 111.9 before 2nd and 3rd GMA sessions. She received her 7th iv IFX while the CDAI was 83.6. GMA course was repeated before 8th and 9th IFX. The patient remained in stable clinical and endoscopic remission without experiencing any serious side effect. After achieving mucosal healing, the patient decided to cease IFX therapy while continuing with GMA. CONCLUSIONS IFX appears to induce and maintain remission of CD, but it may lose its efficacy after repeated administration. GMA is safe and by selectively depleting elevated/activated leukocytes may be a useful adjunct for IFX efficacy.

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
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
Low-CD25(High+)CD4(+), a subset of regulatory CD25(+)CD4(+) T cells and high-inflammatory CD28(-)CD4(+) T cells can exacerbate ulcerative colitis (UC). This study sought to investigate the frequency of CD25(High+)CD4(+) and CD28(-)CD4(+) T cells in patients with UC and the changes in these cells during Adacolumn granulocyte and monocyte adsorption apheresis (GMA). Subjects were 12 patients with active UC, 11 with quiescent UC, and 14 healthy volunteers (HVs). The mean clinical activity index was 15.7 +/- 2.2 in active UC and 4.5 +/- 1.1 in quiescent UC. Peripheral blood samples were stained with CD4, CD25, and CD28 antibodies for flow cytometry. Patients with active UC received GMA and blood samples were examined before and after the first GMA session. Patients with active UC (P < 0.04) or quiescent UC (P < 0.02) had a higher percentage of CD28(-)D4(+)T cells compared with HVs, while the percentage of CD28(+)CD4(+) T cells was lower in both UC groups compared with HVs (P = 0.03 and P < 0.02). Patients with active UC had a lower percentage of CD25(High+)CD4(+)T cells compared with quiescent UC patients (P < 0.001). A significant increase in CD25(High+)CD4(+) T cells was associated with GMA (P < 0.03). Low CD25(High+)CD4(+) and high CD28(-)CD4(+) are prominent features in UC. The increase in CD25(High+)CD4(+) T cells induced by GMA should contribute to improved immune function. Additional studies are warranted, since a low frequency of CD25(High+)CD4(+) (-) and a high frequency of CD28(-)CD4(+) (-) expressing T cells might be a predictor of clinical response to GMA.
