Using a novel subcutaneous dosing schedule, ustekinumab was successful in improving clinical, laboratory, and endoscopic markers of disease activity in patients with severe, refractory CD.

This study describes the advantages and disadvantages of several forms of enteral nutrition for patients with severe head injury (Glasgow Coma Scale Score [GCS], <12). Included in the study are nasoenteric nutrition delivery using blind, endoscopic, percutaneous endoscopic gastrostomy (PEG) and PEG with jejeunostomy (PEG/J), and open jejeunostomy tube placement methods. These methods are compared with parenteral delivery of nutrition. The study constituted a retrospective analysis of the success rate of early enteral feedings by blind, endoscopic PEG and PEG/J and by open jejeunostomy placement of small-bowel feeding tubes for 57 patients with severe head injury. The delivery cost of enteral nutrition per intensive care unit day was compared to the delivery cost of parenteral nutrition per intensive care unit day in the same group of patients. Fifty-three percent of patients were adequately maintained nutritionally with nasoenteric delivery alone and did not require parenteral feeding. The average number of days for initiation of either enteral or parenteral feedings was 1.8 +/- 0.2 days from injury [standard error of mean (SEM); range, 0-10 days]. An average of 3.3 days (range, 0-23 days) was required for feeding tube placement in all patients. For 70% of patients, tube placement was completed within 48 h after injury. Full-strength, full-rate enteral feedings were achieved by a mean of 4.9 days after injury. A total of 128 feeding tubes were placed while the patients were in the intensive care unit (ICU; 2.2 +/- 0.2 tubes per patient). Blind placement of feeding tubes into the small bowel was rarely achieved without repositioning. Endoscopic tube placement into the duodenum was achieved in 50% of patients, into the jejunum for 33% of patients, and into the stomach for 18% of patients. While in the intensive care unit, patients received an average of 77 +/- 2% of their measured energy expenditure (range, 57-114%). Eleven percent of patients experienced severe gastrointestinal problems. Other problems were associated with the inability to achieve or maintain access: dislodged tubes (30%), clogged or kinked tubes (21%), and mechanical access problems (7 %). Seventy-one percent of patients in barbiturate coma were able to tolerate early nasoenteric feedings. Aspiration pneumonitis occurred equally among patients fed nasogastrically and those fed nasoenterically. The overall aspiration rate was 14%. The cost of acute enteral feeding was $170 per day and that for parenteral feeding, $308 per day. We conclude that blind transpyloric feeding tube placement is difficult to achieve in patients with severe head injury; endoscopically guided placement is a better option. Endoscopic feeding tube placement most consistently allows for early enteral nutritional support in severe head injured patients. Limitations include the inability to establish and/or maintain enteral access, increased intracranial pressure, unstable cervical spinal injuries, facial fractures, and dedication of the physician to tube placement and monitoring.

Background In inflammatory bowel disease (IBD), including Crohn’s disease (CD) and ulcerative colitis (UC), nonadherence to biologic therapy increases risk of disease flare. The aim of this study was to identify risk factors for nonadherence. Methods This was a single-center retrospective study evaluating patients with IBD treated at a tertiary care center and prescribed self-injectable biologic therapy using the center’s specialty pharmacy. Adherence was defined using medication possession ratio (MPR). Nonadherence was defined as MPR &lt;0.86. Results Four hundred sixty patients (n = 393 with CD and n = 67 with UC) were evaluated with mean MPR (interquartile range) equaling 0.89 (0.48–1). Overall, 69% of patients were adherent (defined as MPR ≥0.86), 66% of patients with CD and 87% of patients with UC. In univariate analysis, several factors increased risk of nonadherence: CD diagnosis, insurance type, psychiatric history, smoking, prior biologic use, and narcotic use (P &lt; 0.05). In multivariable analysis, Medicaid insurance (odds ratio [OR], 5.5; 95% confidence interval [CI], 1.85–15.6) and CD diagnosis (OR, 2.8; 95% CI, 1.3–6.0) increased risk of nonadherence. In CD, as the number of risk factors increased (narcotic use, psychiatric history, prior biologic use, and smoking), the probability of nonadherence increased. Adherence was 72% in patients with 0–1 risk factors, decreasing to 62%, 61%, and 42% in patients with 2, 3, and 4 risk factors, respectively (P &lt; 0.05). Conclusions This study identified risk factors for nonadherence to biologic therapy. In patients with CD, the probability of nonadherence increased as the number of risk factors increased.

Since 1964 only nine cases of multiple myeloma occurring in the setting of inflammatory bowel disease have been reported. Although this occurrence may be a mere unfortunate coincidence, there are sound pathophysiological reasons for such an event. The possibility that chronic inflammatory conditions, immunomodulator therapy, and infliximab can predispose to multiple myeloma and lymphoma is reviewed. We discuss in detail the only reported case of multiple myeloma arising in the setting of infliximab treatment for Crohn's disease. It is highly probable that infliximab therapy had a causal role in our patient developing multiple myeloma. The pathogenesis of multiple myeloma arising in the setting of infliximab therapy may be related to decreased apoptosis of plasma cell populations. Since it is possible that a causal association exists between infliximab therapy and multiple myeloma, additional screening measures may be required in patients with Crohn's disease on infliximab.

IVIg is safe and effective in the short-term management of patients with IBD when standard therapies are contraindicated.
