ABSTRACT
BACKGROUND & AIMS: Autoimmune sclerosing cholangitis (ASC) is a childhood sclerosing cholangitis frequently associated with inflammatory bowel disease (IBD). We describe the IBD phenotype in ASC patients and associated liver disease outcomes. METHODS: Single center retrospective observational review of ASC patients, with a control population of pediatric IBD. Demographic and clinical parameters were obtained. Clinical endpoints were escalation of IBD therapy (biologic or colectomy) and transplant-free survival. RESULTS: In 93 ASC patients (53.8% female) and median follow up of 172 months: 70% had IBD, 25.8% underwent liver transplant. Median age at liver transplant was 21.7 years, at 131 months from ASC diagnosis. There was no association between presence of IBD and transplant-free survival, whilst those requiring second-line immunomodulators for ASC had poorer long-term liver prognosis. During follow-up 22 (33.8%) ASC-IBD required biologic or colectomy. On multivariate analysis ASC was associated with a lower risk of escalation of IBD therapy (HR 0.14, 95% CI 0.05-0.42; P=.001), including biologic therapy (HR 0.21, 95% CI 0.08-0.55, P=.002), but not colectomy on univariate analysis (HR 1.54, 95% CI 0.43-5.44, P=.51). CONCLUSIONS: IBD is common in ASC and during longterm follow up a third of ASC-IBD required escalation of IBD therapy; however ASC-IBD was lower risk compared to IBD alone. IBD does not appear to impact on transplant-free survival in patients with ASC, however second-line immunomodulators for ASC are associated with poorer IBD and liver outcomes.

Cellulitis of the lower limb is a common presentation in patients with diabetes. We report a case illustrating how Charcot neuropathy can be overlooked because of its resemblance to cellulitis.
ABSTRACT
AIMS: High androgen levels are presumed by many to explain the male predisposition to coronary artery disease. However, natural androgens inhibit male atherosclerosis(1). Our aim was to determine whether levels of androgens differ between men with and without coronary artery disease. METHODS AND RESULTS: Ninety male subjects (60 with positive, and 30 with negative coronary angiograms) were recruited. Early morning, fasting blood samples were taken from each patient and free, total and bioavailable testosterone, sex hormone binding globulin, oestradiol, and lipids were measured. Bioavailable testosterone was assayed using a modified technique. Free androgen index was calculated. Men with coronary artery disease had significantly lower levels of free testosterone (mean (standard deviation)); 47.95 (13.77) vs 59.87 (26. 05) pmol. l(-1), P=0.027), bioavailable testosterone; 2.55 (0.77) vs 3.26 (1.18) nmol. l(-1), P=0.005 and free androgen index; 37.8 (10. 4) vs 48.47 (18.3), P=0.005, than controls. After controlling for differences in age and body mass index the differences in free androgen index and bioavailable testosterone remained statistically significant (P=0.008 and P=0.013, respectively). CONCLUSION: Men with coronary artery disease have significantly lower levels of androgens than normal controls, challenging the preconception that physiologically high levels of androgens in men account for their increased relative risk for coronary artery disease.
