Summary
Background
Crohn's disease recurs in the majority of patients after intestinal resection.
Aim
To compare the relative efficacy of thiopurines and anti‐TNF therapy in patients at high risk of ...disease recurrence.
Methods
As part of a larger study comparing post‐operative management strategies, patients at high risk of recurrence (smoker, perforating disease, ≥2nd operation) were treated after resection of all macroscopic disease with 3 months metronidazole together with either azathioprine 2 mg/kg/day or mercaptopurine 1.5 mg/kg/day. Thiopurine‐intolerant patients received adalimumab induction then 40 mg fortnightly. Patients underwent colonoscopy at 6 months with endoscopic recurrence assessed blind to treatment.
Results
A total of 101 patients 50% male; median (IQR) age 36 (25–46) years were included. There were no differences in disease history between thiopurine‐ and adalimumab‐treated patients. Fifteen patients withdrew prior to 6 months, five due to symptom recurrence (of whom four were colonoscoped). Endoscopic recurrence (Rutgeerts score i2–i4) occurred in 33 of 73 (45%) thiopurine vs. 6 of 28 (21%) adalimumab‐treated patients intention‐to‐treat (ITT); P = 0.028 or 24 of 62 (39%) vs. 3 of 24 (13%) respectively per‐protocol analysis (PPA); P = 0.020. Complete mucosal endoscopic normality (Rutgeerts i0) occurred in 17/73 (23%) vs. 15/28 (54%) (ITT; P = 0.003) and in 27% vs. 63% (PPA; P = 0.002). The most advanced disease (Rutgeerts i3 and i4) occurred in 8% vs. 4% (thiopurine vs. adalimumab).
Conclusions
In Crohn's disease patients at high risk of post‐operative recurrence adalimumab is superior to thiopurines in preventing early disease recurrence.
An estimated 210,000 people were living with hepatitis C virus (HCV) infection in Australia at the end of 2001, and the number of people developing cirrhosis was projected to increase 4-fold by 2020. ...Eighty percent of prevalent and 90% of incident HCV infections are related to injection drug use. Current injection drug use was an exclusion criterion for access to government-funded treatment for HCV infection until May 2001. Despite the removal of this barrier to treatment access for current injection drug users (IDUs), the number of IDUs receiving treatment remains extremely low. Treatment outcomes among IDUs with chronic HCV infection treated at 2 public hospital—based hepatitis clinics are presented. These data demonstrate that IDUs who continue to inject infrequently during treatment for HCV infection can achieve a sustained virological response. Further studies are under way to examine outcomes of treatment for HCV among clients undergoing treatment for drug dependency who have chronic HCV infection and among current IDUs with acute and newly acquired HCV infection.
