We present the case of a 28 year old lady with refractory Crohn's Disease treated with infliximab throughout her pregnancy. Her baby was born healthy and received a Bacillus Calmette-Guérin (BCG) vaccine aged 3 months. Soon after this the infant became unwell and died aged 4.5 months. At post-mortem the cause of death was attributed to an unusual complication of the BCG vaccine, known as disseminated BCG. BCG vaccination is contraindicated in individuals who are receiving immunosuppressive drugs. We recommend physicians should exercise caution before such vaccines are used in infants born to mothers taking anti-TNF therapies or other potentially immunosuppressive IgG1 antibodies.

PDT is minimally invasive but shows a considerable postinterventional cholangitis rate. PDT has the potential to result in a changeover of current palliative treatment of BDC.

In uncontrolled clinical studies, ursodeoxycholic acid (UDCA) had a beneficial effect on nonalcoholic steatohepatitis (NASH). However, a large controlled trial using UDCA (13-15 mg/ kg/day) was unable to confirm these results. Accordingly, a randomized, placebo-controlled study was initiated with a high dose of UDCA (23-28 mg/kg/day). The allocation of patients and the evaluation of liver histology were performed according to a modified Brunt score and the nonalcoholic fatty liver disease activity score (NAS). With the modified Brunt score, 185 patients with histologically proven NASH were randomized [intention to treat (ITT)], and 147 were treated per protocol (PP). With the NAS, 137 patients were confirmed to have NASH, 48 had borderline NASH, and 1 did not have NASH. The treatment time was 18 months. At entry, the treatment groups were comparable. A second biopsy sample was obtained from 139 of 185 patients (NAS: 107/137). The primary criterion for evaluation was a change in the liver histology; the secondary criteria were single histological variables and liver biochemistry. Significant differences in the overall histology could not be detected between the two treatment groups with the modified Brunt score (P 5 0.881) or NAS (P 5 0.355). Only lobular inflammation improved significantly (P for the modified Brunt score 5 0.011, P for NAS 5 0.005). In subgroup analyses, significant improvements in lobular inflammation were also observed in males, younger patients up to 50 years of age, slightly overweight patients, and patients with hypertension and an increased histology score. The fibrosis score did not change (P for ITT 5 0.133, P for PP 5 0.140). With the exception of cglutamyl transferase, UDCA did not improve laboratory data. Conclusion: High-dose UDCA failed to improve the overall histology in patients with NASH in comparison with placebo.
