Safety and efficacy of granulocyte/monocyte apheresis in steroid-dependent active ulcerative colitis with insufficient response or intolerance to immunosuppressants and/or biologics (ART trial): 12-week interim results

International audienceBACKGROUND AND AIMS: Patients with active, steroid-dependent ulcerative colitis with insufficient response or intolerance to immunosuppressants and/or biologic therapies have limited treatment options. Adacolumn, a granulocyte/monocyte adsorptive apheresis device, has shown clinical benefit in these patients. This study aimed to provide additional clinical data regarding the safety and efficacy of Adacolumn in this patient subgroup.METHODS: This single arm, open-label, multicentre trial (ART) was conducted at 18 centres across the UK, France and Germany. Eligible patients were 18-75 years old with moderate-to-severe, steroid-dependent active ulcerative colitis with insufficient response or intolerance to immunosuppressants and/or biologics. Patients received ≥5 weekly apheresis sessions with Adacolumn. The primary endpoint was clinical remission rate (clinical activity index ≤4) at Week 12.RESULTS: Eighty-six patients were enrolled. At Week 12, 33/84 (39.3%) of patients in the intention-to-treat population achieved clinical remission, with 47/84 (56.0%) achieving a clinical response (clinical activity index reduction of ≥3). Clinical remission was achieved in 30.0% of patients with prior immunosuppressant and biologic failure; steroid-free clinical remission and response were observed in 22.6% and 35.7% of these patients, respectively. Quality of life (Short Health Scale) significantly improved at Week 12 (p\textless0.0001). The majority of adverse events were of mild/moderate intensity.CONCLUSIONS: At Week 12, Adacolumn provided significant clinical benefit in a large cohort of steroid-dependent ulcerative colitis patients with previous failure to immunosuppressant and/or biologic treatment, with a favourable safety profile. These results are consistent with previous studies and support Adacolumn use in this difficult-to-treat patient subgrou

Is Surgery Beneficial for MEN1 Patients with Small (≤2 cm), Nonfunctioning Pancreaticoduodenal Endocrine Tumor? An Analysis of 65 Patients from the GTE

Background: The management of small, nonfunctioning pancreaticoduodenal endocrine tumors (NFPET) in multiple endocrine neoplasia type 1 (MEN1) patients is still controversial. We therefore investigated the effect of surgery on survival and tumor progression in MEN1 patients with NFPET ≤2 cm by analyzing data from the Groupe des Tumeurs Endocrines (GTE) registry. Materials and Methods: Among 579 MEN1 patients in the registry, 65 had NFPET ≤ 2 cm. Fifteen (23%) underwent pancreatectomy, 9 at least segmental pancreatectomies and 6 biopsies or enucleations (the surgery group), and 50 (77%) were followed conservatively (the no surgery group). Age at MEN1 and NFPET diagnosis was similar in both groups, as was size of the primary tumor. Seven (10.8%) patients had metastases. Five metastases were synchronous, and 2 (one in each group) were metachronous. Tumor size was similar in patients with or without metastasis. Results: There was no perioperative mortality. The average follow-up time after NFPET diagnosis was 6.7 years in the surgery group and 3.3 years in the no surgery group. Three (4.6%) patients died during follow-up, 2 due to NFPET and 1 due to thymus tumor. The 2 patients who died of NFPET had undergone pancreatic surgery at the time of NFPET diagnosis. The 2 groups did not differ significantly with respect to tumor progression [5/15 (33%) vs 6/38 (16%), P = 0.16]. Overall life expectancy of patients with NFPET ≤2 cm was not different than that of the 229 MEN1 patients in the registry without any pancreaticoduodenal tumor (P = 0.33). Conclusions: This study suggests that surgery may not be beneficial for MEN1 patients with NFPET ≤2 c

Interobserver Variation Study of the Rutgeerts Score to Assess Endoscopic Recurrence after Surgery for Crohn's Disease.

BACKGROUND: After resection surgery for Crohn's disease, recurrence of endoscopic lesions at the site of the anastomosis or in the neoterminal ileum is graded according to the Rutgeerts score (RS). The goal of this study was to test the interobserver variability for RS. METHODS: Thirteen trained endoscopists evaluated the RS on 39 videotapes of patients who had undergone resection for Crohn's disease with an ileocolonic anastomosis 6 months earlier. Videotapes were randomly assigned to endoscopists through a balanced incomplete block design. Each videotape was scored independently by four endoscopists, and each endoscopist evaluated 12 videotapes, making a total of 156 videotape assessments. Reproducibility levels of the RS were assessed through unweighted kappa estimates among multiple raters. The proportion of inappropriate therapeutic initiation was estimated by randomly selecting one endoscopist for each videorecording, assuming that the majority of endoscopists correctly classified endoscopic recurrence. RESULTS: The kappa estimates were 0.43 (95% confidence interval: 0.33-0.52) for the RS on a 5-grade scale, 0.47 (0.28-0.66) for RS /= i2, and 0.64 (0.42-0.85) for RS i2. The percentages of inappropriate therapeutic initiation were 12.8% (3.8-21.9) when initiation was triggered by a RS >/= i2 and 8.3% (1.1-15.6) when initiation was triggered by a RS > i2 (p = 0.41). CONCLUSION: The reproducibility of the RS was moderate, especially when differentiating /=i2, which may lead to incorrect therapeutic decisions in >10% of patients

Prevalence, characteristics and prognosis of MEN 1-associated glucagonomas, VIPomas, and somatostatinomas: study from the GTE (Groupe des Tumeurs Endocrines) registry.

UNLABELLED: Few studies have concerned the rare functioning endocrine pancreatic tumors associated with multiple endocrine neoplasia type 1 (MEN 1). When sporadic, these tumors have a poor prognosis. AIM: To analyze the frequency, characteristics and prognosis of MEN 1-associated glucagonomas, VIPomas and somatostatinomas recorded in the GTE (Groupe des Tumeurs Endocrines) registry. METHODS: Records of the patients whose GTE registry codes included glucagonoma, VIPoma or somatostatinoma were reviewed. The diagnosis was confirmed when there were clinical signs of a functioning tumor and/or when blood levels of the peptide were higher than twice the upper limit of normal. RESULTS: Among 580 patients with MEN 1, duodeno-pancreatic involvement was present in 307 (52.9%). Five (1.6%) had a glucagonoma, 3 (0.98%) a VIPoma and 2 (0.65%) a somatostatinoma. A clinical syndrome was present in 1 patient with glucagonoma, in the 3 with VIPomas and in 1 with somatostatinoma. Tumor size was greater than 3 cm more often for these rare tumours (67%) than in patients with other type of duodeno-pancreatic involvement (28%) (P=0.02) and visceral metastases were more frequent (40% vs 15%; P=0.056). Ten-year survival of patients with glucagonomas, VIPomas or somatostatinomas (53.8%; CI95%: 15.5-92.1) was poorer than that of patients with insulinomas (91.4%; CI95%: 83.399.5; P=0.01) or gastrinomas (81.7%; CI95%: 74.9-88.5; P=0.20) and close to that of patients with non-functioning tumors (62.2%, CI95%: 41.0-83.9; NS). CONCLUSION: Glucagonomas, VIPomas and somatostatinomas, especially the functioning type, are very rare in patients with MEN 1. Prognosis is poor, probably because of large tumor size and high rate of metastasis. Survival is similar to that in patients with non-functioning tumors
