District general hospital networks can provide safe and effective hepatitis C treatment: results of a 5-year audit.

INTRODUCTION: Chronic hepatitis C treatment is well described in randomized-controlled trials (RCTs). We aimed to determine whether these findings can be extrapolated to treatment programmes delivered by nurse specialists in district general hospitals (DGHs). MATERIALS AND METHODS: Within the Dorset viral hepatitis network, chronic hepatitis C patients were treated in three DGHs by nurse specialists working under the supervision of four lead clinicians. Between January 2007 and January 2012, standard of care was ribavirin and pegylated interferon-α2a administered for 24 weeks (G2/3) and 48 weeks (G1/4). Retrospective analysis of the network's database was carried out and comparisons were made with a multicentre RCT. RESULTS: In total, 242 completed patient episodes were available for analysis. Ninety per cent (219) were treatment naive. G1 patients represented 49% (107) of this cohort; 2% (six) were hepatitis B/HIV coinfected and 97% (212) were Whites. Overall, 11% (23) were lost to follow-up within 24 weeks of completing treatment. On the basis of the intention to treat, the sustained virological response rates were 45 (48/107), 60 (63/105) and 57% (4/7) for patients infected with hepatitis C virus G1, G2/3 and G4, respectively. These results are comparable with RCT data (P=0.4973, 0.1359 and 0.9552). Treatment was discontinued in 3.7% (eight) of patients because of a laboratory abnormality and 9.6% (21) because of other medical complications or side-effect intolerance. These proportions are similar to those observed in the RCT (P=0.0873 and 0.5613). CONCLUSION: Specialist nurses supported by a network of DGHs can deliver a high-quality hepatitis C service across a broad geographical area.

A case-control study of childhood environmental risk factors for the development of inflammatory bowel disease.

OBJECTIVE: To clarify the relationship between childhood environment and the risk of subsequent development of Crohn's disease or ulcerative colitis. DESIGN AND OUTCOME MEASURES: A case-control study, assessing the risk of inflammatory bowel disease in relation to a series of historical and serological markers of childhood circumstance, analysed using the maximum likelihood form of conditional logistic regression. SETTING: District general hospital (secondary care institution). PARTICIPANTS: Subjects with Crohn's disease (n = 139) or ulcerative colitis (n = 137) aged between 16 and 45 years, each matched for sex and age with an outpatient control. RESULTS: Helicobacter seroprevalence was substantially reduced in Crohn's disease (OR 0.18; 95% CI, 0.06-0.52) but not in ulcerative colitis (OR 0.91; 95% CI, 0.38-2.16). In ulcerative colitis, a strong negative association with childhood appendectomy was confirmed (OR 0.05; 95% CI, 0.01-0.51). Crohn's disease was associated with childhood eczema (OR 2.81; 95% CI, 1.23-6.42) and the frequent use of a swimming pool (OR 2.90; 95% CI 1.21-6.91). There was no association between hepatitis A seroprevalence and either disease. CONCLUSION: The findings are consistent with the hypothesis that improved childhood living conditions are associated with increased risk of Crohn's disease. The study confirms that the negative association between appendectomy and ulcerative colitis relates primarily to events in childhood. Overall, the findings strongly support the assertion that childhood environment is an important determinant of the risk of inflammatory bowel disease in later life, with quite distinct risk factors for ulcerative colitis and Crohn's disease.
