Abstract We aimed to determine the risk of incident cancer in autoimmune hepatitis (AIH) compared to the general population and siblings. AIH was defined by the presence of a medical diagnosis of AIH and a liver biopsy in a nationwide Swedish population-based cohort study. We identified 5,268 adults with AIH diagnosed 1969-2016 and 22,996 matched general population reference individuals and 4,170 sibling comparators. Using Cox regression, hazard ratios (HRs) were determined for any incident cancer and sub-types determined from the Swedish Cancer Register. During follow-up, a cancer diagnosis was made in 1,119 individuals with AIH (17.2/1000 person-years) and 4,450 reference individuals (12.0/1000 person-years). This corresponded to an HR of 1.53 (95%CI: 1.42,1.66). Cancer risk was highest in those with cirrhosis. There was a 29.18-fold increased risk of hepatocellular carcinoma (HCC) (95%CI, 17.52,48.61). The annual incidence risk of HCC in individuals with AIH who had cirrhosis was 1.1% per year. AIH was also linked to non-melanoma skin cancer (HR=2.69) and lymphoma (HR=1.89). Sibling analyses yielded similar risk estimates for any cancer (HR=1.84) and HCC (HR=23.10). AIH is associated with an increased risk of any cancer, in particular, HCC and extra-hepatic malignancies. The highest risk for cancer, especially HCC, is in patients with cirrhosis.

Adverse Perinatal Outcomes

Abstract Background Racial disparities in adverse perinatal outcomes have been studied in other countries, but little has been done for the Canadian population. In this study, we sought to examine the disparities in adverse perinatal outcomes between Asians and Caucasians in Ontario, Canada. Methods We conducted a population-based retrospective cohort study that included all Asian and Caucasian women who attended a prenatal screening and resulted in a singleton birth in an Ontario hospital (April 1st, 2015-March 31st, 2017). Generalized estimating equation models were used to estimate the independent adjusted relative risks and adjusted risk difference of adverse perinatal outcomes for Asians compared with Caucasians. Results Among 237,293 eligible women, 31% were Asian and 69% were Caucasian. Asians were at an increased risk of gestational diabetes mellitus, placental previa, early preterm birth (< 32 weeks), preterm birth, emergency cesarean section, 3rd and 4th degree perineal tears, low birth weight (< 2500 g, < 1500 g), small-for-gestational-age (<10th percentile, <3rd percentile), neonatal intensive care unit admission, and hyperbilirubinemia requiring treatment, but had lower risks of preeclampsia, macrosomia (birth weight > 4000 g), large-for-gestational-age neonates, 5-min Apgar score < 7, and arterial cord pH ≤7.1, as compared with Caucasians. No difference in risk of elective cesarean section was observed between Asians and Caucasians. Conclusion There are significant differences in several adverse perinatal outcomes between Asians and Caucasians. These differences should be taken into consideration for clinical practices due to the large Asian population in Canada.
