Background: Concurrent extrahepatic autoimmune disease (CEHAID) associated with

Aim: Drug-induced autoimmune hepatitis (DIAIH) remains poorly characterized. Our aim was to assess natural history and outcomes in DIAIH.Methods: This was a retrospective cohort study. Results: Eighty-two patients with autoimmune hepatitis (AIH) were identified, 11 (13.4%) with DIAIH, implicated drugs being nitrofurantoin (n = 4), statins (n = 4), herbal remedies (n = 2) and diclofenac (n = 1). Female sex, acute onset, elevated serum globulins/immunoglobulin G, fibrosis stage (Ishak), cirrhosis at onset, moderate-severe portal inflammation, interface and lobular hepatitis, remission, relapse and poor outcome were similar in those with DIAIH and AIH (P > 0.05). The former were however more likely to be aged 60 years or more and take longer to relapse on immunosuppression discontinuation (P = <0.05). On Kaplan-Meier analysis, probability of poor outcome was similar in those with DIAIH and AIH (log-rank test, 0.339). On comparing those with (n = 4) and without nitrofurantoin (n = 7) DIAIH, the former were older, had longer duration of drug use prior to DIAIH diagnosis, higher fibrosis stage and were less likely to relapse upon immunosuppression discontinuation. Conclusion:Approximately 15% of patients with AIH have DIAIH with similar outcomes, although the latter are older with a propensity for late relapse, mandating long-term follow up.

Background: Abdominal wall hernia is a common surgical condition. Patients may present in an emergency with bowel obstruction, incarceration or strangulation. Small bowel obstruction (SBO) is a serious surgical condition associated with significant morbidity. The aim of this study was to describe current management and outcomes of patients with obstructed hernia in the UK as identified in the National Audit of Small Bowel Obstruction (NASBO). Methods: NASBO collated data on adults treated for SBO at 131 UK hospitals between January and March 2017. Those with obstruction due to abdominal wall hernia were included in this study. Demographics, co-morbidity, imaging, operative treatment, and in-hospital outcomes were recorded. Modelling for factors associated with mortality and complications was undertaken using Cox proportional hazards and multivariable regression modelling. Results: NASBO included 2341 patients, of whom 415 (17⋅7 per cent) had SBO due to hernia. Surgery was performed in 312 (75⋅2 per cent) of the 415 patients; small bowel resection was required in 198 (63⋅5 per cent) of these operations. Non-operative management was reported in 35 (54 per cent) of 65 patients with a parastomal hernia and in 34 (32⋅1 per cent) of 106 patients with an incisional hernia. The in-hospital mortality rate was 9⋅4 per cent (39 of 415), and was highest in patients with a groin hernia (11⋅1 per cent, 17 of 153). Complications were common, including lower respiratory tract infection in 16⋅3 per cent of patients with a groin hernia. Increased age was associated with an increased risk of death (hazard ratio 1⋅05, 95 per cent c.i. 1⋅01 to 1⋅10; P = 0⋅009) and complications (odds ratio 1⋅05, 95 per cent c.i. 1⋅02 to 1⋅09; P = 0⋅001). Conclusion: NASBO has highlighted poor outcomes for patients with SBO due to hernia, highlighting the need for quality improvement initiatives in this group. *Members of the National Audit of Small Bowel Obstruction (NASBO) Steering Group and NASBO Collaborators are co-authors of this study and are listed in Appendix S1 (supporting information) Funding information
