Recalcitrant plantar warts during azathioprine therapy for Crohn's disease.

Dermatological complications of long-term immunosuppressive therapy in inflammatory bowel disease (IBD) are rarely reported. We present the case of a 29-year-old man with worsening of plantar warts while on azathioprine therapy for Crohn's disease. This case underlines the need to perform thorough skin examination of IBD patients before and during immunosuppressive therapy.

Laparoscopic ileocolic resection versus infliximab treatment of distal ileitis in Crohn's disease: a randomized multicenter trial (LIR!C-trial).

BACKGROUND: With the availability of infliximab, nowadays recurrent Crohn's disease, defined as disease refractory to immunomodulatory agents that has been treated with steroids, is generally treated with infliximab. Infliximab is an effective but expensive treatment and once started it is unclear when therapy can be discontinued. Surgical resection has been the golden standard in recurrent Crohn's disease. Laparoscopic ileocolic resection proved to be safe and is characterized by a quick symptom reduction. The objective of this study is to compare infliximab treatment with laparoscopic ileocolic resection in patients with recurrent Crohn's disease of the distal ileum with respect to quality of life and costs. METHODS/DESIGN: The study is designed as a multicenter randomized clinical trial including patients with Crohn's disease located in the terminal ileum that require infliximab treatment following recent consensus statements on inflammatory bowel disease treatment: moderate to severe disease activity in patients that fail to respond to steroid therapy or immunomodulatory therapy. Patients will be randomized to receive either infliximab or undergo a laparoscopic ileocolic resection. Primary outcomes are quality of life and costs. Secondary outcomes are hospital stay, early and late morbidity, sick leave and surgical recurrence. In order to detect an effect size of 0.5 on the Inflammatory Bowel Disease Questionnaire at a 5% two sided significance level with a power of 80%, a sample size of 65 patients per treatment group can be calculated. An economic evaluation will be performed by assessing the marginal direct medical, non-medical and time costs and the costs per Quality Adjusted Life Year (QALY) will be calculated. For both treatment strategies a cost-utility ratio will be calculated. Patients will be included from December 2007. DISCUSSION: The LIR!C-trial is a randomized multicenter trial that will provide evidence whether infliximab treatment or surgery is the best treatment for recurrent distal ileitis in Crohn's disease. TRIAL REGISTRATION: Nederlands Trial Register NTR1150.

Effects of growth hormone deficiency and recombinant growth hormone therapy on postprandial gallbladder motility and cholecystokinin release.

In addition to cholecystokinin, other hormones have been suggested to be involved in regulation of postprandial gallbladder contraction. We aimed to evaluate effects of growth hormone (GH) on gallbladder contractility and cholecystokinin release. Gallbladder and gastric emptying (by ultrasound) and cholecystokinin release were determined before and after 6 months of recombinant human GH (rhGH) therapy in 12 patients with GH deficiency, after either a mixed (n = 5) or a liquid (n = 7) meal. Basal postprandial gallbladder contraction was severely impaired (19 +/- 2 and 26 +/- 3% of fasting volume after mixed and liquid meal, respectively). Histology and cholecystokinin sulfation patterns in duodenal biopsies from two patients were normal. After 6 months of rhGH therapy, fasting gallbladder volumes increased (from 20.8 +/- 0.9 to 25.9 +/- 1.1 mL, P < 0.05) and postprandial gallbladder emptying was restored (70 +/- 6 and 70 +/- 7% of fasting volume after mixed and liquid meal, respectively), without change of gastric emptying. Cholecystokinin secretion after a mixed meal and gallbladder sensitivity to cholecystokinin were significantly enhanced during rhGH replacement compared to the basal state. Postprandial cholecystokinin release, gallbladder responsiveness to cholecystokinin, and gallbladder emptying are severely impaired in the absence of GH. Reversibility during GH suppletion suggests its involvement in regulation of gallbladder contractility.

Benign recurrent intrahepatic cholestasis progressing to progressive familial intrahepatic cholestasis: low GGT cholestasis is a clinical continuum.

Benign recurrent intrahepatic cholestasis (BRIC) is an autosomal recessive liver disease, characterised by intermittent attacks of cholestasis, which can start at any age and last for several weeks to months. Characteristically serum GGT activity is low and normal liver structure is preserved. Progressive familial intrahepatic cholestasis (PFIC) is another liver disease, characterised by severe cholestasis, starting almost invariably before 6 months of age. All patients progress to cirrhosis, liver failure and death, unless a liver transplantation is performed. We now identified four patients who presented in childhood with recurrent attacks of cholestasis, while in the course of the disease the cholestasis gradually became permanent. Although liver biopsies performed in the early stages of the disease showed normal liver architecture, late stage biopsies revealed evident fibrosis with porto-portal septa formation. In conclusion, the disease of these patients started with the clinical and histopathological characteristics of BRIC but progressed to PFIC.
