Background and Aims: Previous studies have shown suboptimal screening for hepatitis D virus (HDV) among patients with chronic hepatitis B (CHB). This study presents the cascade of care for HDV infection in a major secondary referral centre in Southern Stockholm, Sweden. Methods: HBsAg+ve patients attending Karolinska University Hospital (KUH) from 1992 to 2022 were identified. The prevalence of anti‐HDV and/or HDV RNA positivity, interferon (IFN) therapy and maintained virological responses (MVR) after HDV treatment were assessed. Also, time to anti‐HDV testing was analysed in relation to liver‐related outcomes with logistic regression. Results: Among 4095 HBsAg+ve persons, 3703 (90.4%) underwent an anti‐HDV screening; within a median of 1.8 months (range 0.0–57.1) after CHB diagnosis. This screening rate increased over time, to 97.9% in the last decade. Overall, 310 (8.4%) were anti‐HDV+ve, of which 202 (65.2%) were HDV RNA+ve. Eighty‐five (42%) received IFN, and 9 (10.6%) achieved MVR at the last follow‐up. The predictive factors for anti‐HDV screening were Asian origin, diagnosis after the year 2012, HIV co‐infection (negative factor) and HBV DNA level < 2000 IU/mL in univariable analysis, while HIV co‐infection was the only remaining factor in multivariable analysis. Delayed anti‐HDV test >5 years was independently associated with worsened liver‐related outcomes (adjusted odds ratio = 7.6, 95% CI 1.8–31.6). Conclusion: Higher frequency of HDV screening than previously published data could be seen among CHB patients at KUH in a low‐endemic setting. Receiving a delayed screening test seems to be associated with worse outcomes, stressing the need of a strategy for timely HDV diagnosis. [ABSTRACT FROM AUTHOR]

Background & Aims: Mutations in the HFE gene can lead to hereditary haemochromatosis (HH) and have been suggested to increase the risk of extra‐hepatic diseases, especially breast and colorectal cancer. Here we investigated long‐term outcomes of Swedish patients with HFE mutations. Methods: We identified 3645 patients with a homozygous p.C282Y (62%) or a compound heterozygous p.C282Y/p.H63D (38%) mutation from eight centres in Sweden between 1997 and 2017. These were matched 1:10 by age, sex and county of residence to reference individuals from the general population. We ascertained incident outcomes until the end of 2017 by linkage to national registers. Studied outcomes were HH, cirrhosis, hepatocellular carcinoma (HCC), breast cancer (in women), colorectal cancer, type 1 and 2 diabetes, hypothyroidism, Parkinson's disease and mortality. Cox proportional hazards regression was used to estimate hazard ratios for these outcomes. Results: Median age at diagnosis was 52 years, 44% were females. During a mean follow‐up of 7.9 years, we found an increased risk for HCC, HH, cirrhosis, type 2 diabetes, osteoarthritis and death. Excess mortality was only seen in men. No increased risk was seen for colorectal or breast cancer. Liver‐related outcomes were rare, with a cumulative incidence of <1%. Conclusions: Individuals found to be HFE mutation carriers in a university hospital setting had an increased risk for mortality in men, along with increased risks of cirrhosis, HCC, diabetes type 2, and osteoarthritis. In general, the absolute risk for adverse outcomes was low and no increased risk for colon or breast cancer was observed. [ABSTRACT FROM AUTHOR]

Background & Aims: Patients with non‐alcoholic fatty liver disease (NAFLD) are at an increased risk for cardiovascular disease (CVD). It is unclear whether histological variables may help predict CVD risk. We evaluated histology and traditional CV risk factors as predictors of CVD outcomes in a large NAFLD cohort. Methods: We included 603 biopsy‐proven NAFLD patients free of baseline CVD and matched these (1:10, by age, sex and municipality) to 6269 population controls. All individuals were cross‐linked to national registries to ascertain incident CVD events, defined as acute ischaemic heart disease or stroke. The presence of CV risk factors and liver histology were available in NAFLD patients only. Cox regression models were used to estimate hazard ratios (HR) for incident CVD. Results: During a mean follow‐up of 18.6 years, 168 (28%) of NAFLD patients and 1325 (21%) of controls experienced a CVD event (HR 1.54, 95%CI 1.30‐1.83). Within the NAFLD cohort, age, male sex, type 2 diabetes, smoking and triglycerides were associated with risk of CVD. Taking these CV risk factors into account, no histological parameter, including presence of NASH and fibrosis stage, were associated with incident CVD. Conclusions: Patients with NAFLD are at an increased risk for CVD compared to matched controls, but histological parameters do not seem to independently predict this risk. [ABSTRACT FROM AUTHOR]

Abstract: Background & Aims: Prognostication in hepatocellular carcinoma (HCC) is demanding. Not only tumour extent and performance status are to be considered, but also liver function, which is often limiting for both survival itself and for treatment possibilities. This study was conducted to assess whether patient‐reported questionnaires containing general and liver‐specific questions could improve prognostication of survival. Methods: 185 patients with hepatocellular carcinoma in Norway and Sweden were prospectively included. Patients completed the quality‐of‐life questionnaires EORTC QLQ C30 and HCC18, and clinical, radiological and laboratory parameters were registered. Multivariate Cox regression and Harrell's C‐statistics were used to identify the model that best predicted mortality. Results: Quality‐of‐life data were prognostic for overall survival. Fatigue and nutrition scales were prognostic in the multivariable analyses alone and in combination with clinical parameters. The prognostic value of established scoring systems was increased by the addition of QoL data. The best prognostic power was achieved by combining HCC18 nutrition scale with selected background parameters. Conclusion: Quality‐of‐life questionnaires can prognosticate mortality in HCC patients. When combined with established scoring systems, both the general cancer questionnaire EORTC QLQ C30, and the additional liver cancer‐specific HCC18 increased the prognostic accuracy slightly.
