Enterovirus infection during pregnancy is inversely associated with atopic disease in the offspring.

BACKGROUND: Prenatal environment has been shown to influence child's risk of atopic diseases. Laboratory-confirmed data about the role of maternal infections during pregnancy is scarce. OBJECTIVE: The aim of this study was to determine the associations between serologically confirmed maternal infections during pregnancy and atopic disease in the offspring. METHODS: This was a nested case-control study within a prospective birth cohort study. Altogether 202 atopic case children and 333 matched non-atopic control children were included. Atopic outcome was defined as having an atopic disease and IgE sensitization by the age of 5 years. We analysed serologically acute enterovirus (EV), influenza virus A (IAV) and Mycoplasma pneumoniae (M. pneumoniae) infections during pregnancy, and mother's seropositivity against human cytomegalovirus (CMV) and Helicobacter pylori. RESULTS: Maternal EV infection during pregnancy was inversely associated with atopic outcome in the offspring (odds ratio 0.43; 95% confidence interval: 0.23-0.80, P = 0.008). Acute IAV or M. pneumoniae infections or seropositivity against CMV or Helicobacter pylori were not associated with the atopic outcome. CONCLUSIONS AND CLINICAL RELEVANCE: Our results suggest that maternal EV infections during pregnancy are inversely associated with atopic disease in the offspring. Our finding provides further support to the previous studies suggesting an important role of the in utero environment in the development of atopic diseases.

Treatment trends and outcomes of hepatocellular carcinoma in a single center for 35 years.

BACKGROUND: Hepatocellular carcinoma (HCC) is one of the leading causes of cancer mortality. The aim of this study was to examine the trends of HCC treatment and the outcomes in a single tertiary center for 35 years. METHODS: Two hundred seventy-three consecutive HCC patients between 1983-2018 were identified from Oulu University Hospital records. Primary outcomes of the study were postoperative complications within 30 days after the operation, and short- (30- and 90-day) and long-term (1, 3 and 5-year) survival. RESULTS: Of the 273 patients, 49 underwent surgical resection, 25 local ablation, 48 angiological treatment and 151 had palliative treatment. The rate of surgery declined over time, while other invasive treatments increased. Major complications occurred in 14 (28.6%) patients after surgical resection, in 2 (8.0%) patients after local ablation and in 13 (27.1%) patients after angiological treatment (P=0.022). Recurrence and local recidives were observed especially in local ablation group and in angiological treatment group (P<0.001). Overall survival rates in surgical resection group were at 30 and 90 days, 1-, 3- and 5-years 95.9%, 95.9%, 85.1%, 59.0% and 51.2%. In local ablation group, respective overall survival rates were 100.0%, 100.0%, 86.1%, 43.1% and 18.8%, and in angiological group 95.8%, 93.6%, 56.1%, 26.3% and 6.6%. In cox regression model adjusted for confounding factors, mortality hazard was lowest after surgical resection. Prognosis was poor in palliative group. CONCLUSIONS: Based on this Northern Finland population, the surgical resection of HCC has acceptable complication rate compared to other treatments; and yields the best long-term survival. Overall prognosis of HCC remains poor.
