SummaryWhile splenectomy is an effective therapy for primary immune thrombocytopenia (ITP), possible complications and observed noncomplete response (CR) in one-third of patients demonstrate the need for further research into potential pre-surgical predictors of outcomes. Past investigations into platelet sequestration studies, a hypothesized predictive test, have adopted heterogeneous methods and varied widely with regard to power. By studying patients with primary ITP who underwent autologous 111 In-labelled platelet sequestration studies at Barts and The London NHS Trust between 1994 and 2008, we evaluated the effectiveness of sequestration site in predicting short, medium, and long-term CR (platelet count >100 · 10 9 /l) to splenectomy through multivariate (gender, age at splenectomy, and mean platelet lifespan) logistic regression modelling. In total, 256 patients with primary ITP underwent scans; 91 (35AE5%) proceeded to splenectomy. Logistic regression revealed significant adjusted odds ratios for CR of 7AE47 (95% confidence interval [CI], 1AE89-29AE43) at 1-3 months post-splenectomy, 4AE85 (95% CI, 1AE04-22AE54) at 6-12 months postsplenectomy, and 5AE39 (95% CI, 1AE34-21AE65) at last follow-up (median: 3AE8 years [range: 0AE5-13AE1 years]) in patients with purely or predominantly splenic versus mixed or hepatic sequestration. These findings demonstrate the utility of autologous 111 In-labelled platelet sequestration studies as an adjunct predictive instrument prior to splenectomy.
NSAID- related enteropathy is common and often presents subclinically. The most common presentation is anaemia, which may be less common in those on cyclo-oxygenase (COX)-2 inhibitors than nonselective NSAIDs. PPI use worsens NSAID enteropathy with more occult bleeding and ulceration and has been linked to gram-negative intestinal dysbiosis. If NSAID cessation is not possible, COX-2 inhibition without PPI therapy should be considered in patients with upper gastrointestinal risk factors. Mucoprotective agents such as misoprostol and rebamipide show promise and probiotics may have a future role.
Background Endoscopically defined mucosal healing in Crohn’s disease is associated with improved outcomes. Panenteric capsule endoscopy enables a single non-invasive assessment of small and large bowel mucosal inflammation. Aims and methods: This multicentre observational study of patients with suspected and established Crohn’s disease examined the feasibility, safety and impact on patient outcomes of panenteric capsule endoscopy in routine clinical practice. The potential role in assessment of disease severity and extent by a comparison with existing clinical and biochemical markers is examined. Results Panenteric capsule endoscopy was performed on 93 patients (71 with established and 22 with suspected Crohn’s disease). A complete examination occurred in 85% (79/93). Two cases (2.8%) of capsule retention occurred in patients with established Crohn’s disease. Panenteric capsule resulted in management change in 38.7% (36/93) patients, including 64.6% (32/48) of those with an established diagnosis whose disease was active, and all three patients with newly diagnosed Crohn’s disease. Montreal classification was upstaged in 33.8% of patients with established Crohn’s disease and mucosal healing was demonstrated in 15.5%. Proximal small bowel disease upstaged disease in 12.7% and predicted escalation of therapy (odds ratio 40.3, 95% confidence interval 3.6–450.2). Raised C-reactive protein and faecal calprotectin were poorly sensitive in detecting active disease (0.48 and 0.59 respectively). Conclusions Panenteric capsule endoscopy was feasible in routine practice and the ability to detect proximal small bowel disease may allow better estimation of prognosis and guide treatment intensification. Panenteric capsule endoscopy may be a suitable non-invasive endoscopic investigation in determining disease activity and supporting management decisions.
Non-steroidal anti-inflammatory drugs (NSAIDs) are used commonly but can cause foregut symptoms, peptic ulcer disease and small bowel enteropathy. Such iatrogenic injury can be complicated by gastrointestinal bleeding and perforation. Limiting NSAID use or co-administration with proton pump inhibitors (PPIs) reduce dyspepsia, peptic ulcer disease and rates of complications. Selective cyclo-oxygenase (COX)-2 inhibitors are as effective as adding PPIs in preventing upper and lower gastrointestinal complications. COX-2 inhibitors are suggested in those with high cardiovascular risk and the addition of PPI in those with high risk of bleeding. Where required, COX-2 inhibitor monotherapy may be preferred in unexplained iron deficiency anaemia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
