Antimigration versus conventional fully covered metal stents in the endoscopic treatment of anastomotic biliary strictures after deceased-donor liver transplantation.

INTRODUCTION: Migration of fully covered metal stents (FCMS) remains a limitation of the endoscopic treatment of anastomotic biliary strictures (ABS) following orthotopic liver transplantation (OLT). The use of antimigration FCMS (A-FCMS) might enhance endoscopic treatment outcomes for ABS. METHODS: Single center retrospective study. Consecutive patients with ABS following OLT who underwent ERCP with FCMS placement between January 2005 and December 2020 were eligible. Subjects were grouped into conventional-FCMS (C-FCMS) and A-FCMS. The primary outcome was stent migration rates. Secondary outcomes were stricture resolution, adverse event, and recurrence rates. RESULTS: A total of 102 (40 C-FCMS; 62 A-FCMS) patients were included. Stent migration was identified at the first revision in 24 C-FCMS patients (63.2%) and in 21 A-FCMS patients (36.2%) (p = 0.01). The overall migration rate, including the first and subsequent endoscopic revisions, was 65.8% in C-FCMS and 37.3% in A-FCMS (p = 0.006). The stricture resolution rate at the first endoscopic revision was similar in both groups (60.0 vs 61.3%, p = 0.87). Final stricture resolution was achieved in 95 patients (93.1%), with no difference across groups (92.5 vs 93.5%; p = 0.84). Adverse events were identified in 13 patients (12.1%) with no difference across groups. At a median follow-up of 52 (IQR: 19-85.5) months after stricture resolution, 25 patients (24.5%) developed recurrences, with no difference across groups (C-FCMS 30% vs A-FCMS 21%; p = 0.28). CONCLUSIONS: The use of A-FCMS during ERCP for ABS following OLT results in significantly lower stent migration rates compared to C-FCMS. However, the clinical benefit of reduced stent migration is unclear. Larger studies focusing on stricture resolution and recurrence rates are needed.

Effectiveness and Safety of Ustekinumab in Elderly Patients with Crohn's Disease: Real World Evidence From the ENEIDA Registry.

BACKGROUND AND AIMS: Clinical trials and real-life studies with ustekinumab in Crohn's disease [CD] have revealed a good efficacy and safety profile. However, these data are scarcely available in elderly patients. Therefore, we aim to assess the effectiveness and safety of ustekinumab in elderly patients with CD. METHODS: Elderly patients [>60 years old] from the prospectively maintained ENEIDA registry treated with ustekinumab due to CD were included. Every patient was matched with two controls under 60 years of age, according to anti-tumour necrosis factor use and smoking habit. Values for the Harvey-Bradshaw Index [HBI], endoscopic activity, C-reactive protein [CRP] and faecal calprotectin [FC] were recorded at baseline and at weeks 16, 32 and 54. RESULTS: In total, 648 patients were included, 212 of whom were elderly. Effectiveness was similar between young and elderly patients during the follow-up. Steroid-free remission was similar at week 16 [54.6 vs 51.4%, p = 0.20], 32 [53.0% vs 54.5%, p = 0.26] and 54 [57.8% vs 51.1%, p = 0.21]. Persistence of ustekinumab as maintenance therapy was similar in both age groups [log-rank test; p = 0.91]. There was no difference in the rate of adverse effects [14.2% vs 11.2%, p = 0.350], including severe infections [7.1% vs 7.3%, p = 1.00], except for the occurrence of de novo neoplasms, which was higher in older patients [0.7% vs 4.3%, p = 0.003]. CONCLUSIONS: Ustekinumab is as effective in elderly patients with CD as it is in non-elderly patients. The safety profile also seems to be similar except for a higher rate of de novo neoplasms, probably related to the age of the elderly patients.

The practical utility of non-invasive indices in metabolic hepatic steatosis.

BACKGROUND: Metabolic hepatic steatosis (metHS) is the most frequent cause of chronic liver disease in our environment. The "gold standard" for its diagnosis continues to be liver biopsy, but this is an invasive technique, is not risk-free, and has great interobserver variability, so noninvasive diagnostic methods are necessary. OBJECTIVE: To determine the diagnostic accuracy of non-invasive methods based on clinical and analytical data compared to liver biopsy, and to analyse their concordance with each other in the overall cohort and in subpopulations at risk of metHS. METHODS: Prospective observational study of 245 patients aged 19-80 years diagnosed with metHS by liver biopsy. Steatosis indices were calculated: FLI (Fatty Liver Index), LAP (Liver Accumulation Product), HSI-(Hepatitis Score Index) and fibrosis indices: Non-alcoholic fatty liver disease fibrosis score (NFS), fibrosis-4 index (FIB-4) and Hepamet Fibrosis Score (HFS). RESULTS: The non-invasive steatosis indices showed high sensitivity, and those of fibrosis, high specificity. To assess steatosis, FLI was the most sensitive index in all subpopulations (89-97%), except in women. To assess fibrosis, HFS offers maximum sensitivity in diabetics (86.7%) and is the index with the highest negative predictive value overall. The COR curves for non-invasive indices in steatosis and fibrosis compared to liver biopsy showed greater areas under the curve for the fibrosis indices, with NFS and HFS offering greater diagnostic accuracy (area > 0.8, p < 0.05). HFS also offers high diagnostic sensitivity in the diabetic population. CONCLUSIONS: Non-invasive indices of steatosis are more sensitive and those of fibrosis more specific than liver biopsy. NFS and HFS offer the highest diagnostic accuracy, with HFS having the highest negative predictive value.

Gastric plasmacytoma: a rare cause of upper gastrointestinal bleeding.

A 43-year-old female presented to our department with hemoglobin of 3.4 g/dl. She denied gastrointestinal bleeding or weight loss. An upper endoscopy revealed an ulcerative lesion on the greater curvature of the gastric body with two visible clots. Two hemoclips were needed to attain hemostasis, as one of the biopsies of the tumor caused active spurting bleeding. An abdominal computed tomography (CT) demonstrated a well-circumscribed intramural mass arising in the gastric wall, measuring 65 x 50 x 90 mm, with marked internal vascularity and extraluminal component associated. The biopsies identified areas of mature and immature plasmocytes.

Prevalence and factors associated with poor sleep quality in inflammatory bowel disease outpatients.

INTRODUCTION: sleep disorders are common in the general population and have obvious repercussions on quality of life. Poor sleep quality is associated to inflammatory activity and fatigue in inflammatory bowel disease (IBD) patients. This study aimed to analyze the prevalence of poor sleep quality and the factors associated with it, in IBD outpatients. METHODS: an observational and prospective study was performed in which epidemiological, clinical and laboratory data were collected from clinical records and patients who consecutively attended an outpatient clinic. Pittsburgh Sleep Quality index (PSQI), Hospital Anxiety and Depression Scale (HADS) and International Physical Activity Questionnaire (IPAQ) were used to measure sleep quality, anxiety, depression and physical activity, respectively. Treatment optimizations, hospital admissions or surgery were prospectively verified three months after the baseline visit. RESULTS: one hundred and two patients were included and 54.9 % had poor sleep quality (PSQI score > 5). No association was found between poor sleep quality and IBD-related variables such as type of disease, ulcerative colitis (UC) extent, Crohn's disease (CD) location or behavior, time from diagnosis, treatment, prior admissions or surgery and laboratory values. Rotating night shift job (OR 6.116, 95 % CI: 1.312-28.514), HAD score for depression (OR 1.125, 95 % CI: 1.062-1.490) and frequency (days per week) of vigorous physical activity (OR 0.783, 95 % CI: 0.619-0.991) were independent predictors of poor sleep quality. A Pittsburgh questionnaire score higher than 5 was not significantly associated to treatment optimization in the total patient cohort (15.2 % vs 18.2 %, p = 0.451), in UC patients (18.2 % vs 10.7 %, p = 0.362) or CD patients (12.5 % vs 25.9 %, p = 0.198). CONCLUSIONS: poor sleep quality is present in more than half of IBD patients. Aspects not directly related to IBD are associated to poor sleep quality.
