  Title Association of iron status with the risk of bloodstream infections: results from the prospective population-based HUNT Study in Norway Type Journal Article

  Abstract PURPOSE: As iron is essential for both immune function and microbial growth, alterations in iron status could influence the risk of infections. We assessed the associations of iron status with risk of bloodstream infections (BSIs) and BSI mortality. METHODS: We measured serum iron, transferrin saturation (Tsat) and total iron-binding capacity (TIBC) in 61,852 participants in the population-based HUNT2 study (1995-97). Incident BSIs (1995-2011) were identified through linkage with the Mid-Norway Sepsis Register, which includes prospectively registered information on BSI from local and regional hospitals. We assessed the risk of a first-time BSI and BSI mortality with the iron indices using Cox proportional hazards regression analysis. RESULTS: During a median follow-up of 14.8 years, 1738 individuals experienced at least one episode of BSI, and 370 died within 30 days after a BSI. In age- and sex-adjusted analyses, BSI risk was increased among participants with indices of iron deficiency, serum iron </= 2.5th percentile (HR 1.72, 95% CI 1.34-2.21), Tsat </= 2.5th percentile (HR 1.48, 95% CI 1.12-1.96) or TIBC >/= 97.5th percentile (HR 1.46, 95% CI 1.06-2.01). The associations remained similar after adjusting for comorbidities and exclusion of BSI related to cancer, rheumatic illnesses and inflammatory bowel disease. BSI mortality showed similar associations. CONCLUSION: Indices of severe iron deficiency are associated with an increased risk of a future BSI.

  Title Associations of obesity and lifestyle with the risk and mortality of bloodstream infection in a general population: a 15-year follow-up of 64 027 individuals in the HUNT Study Type Journal Article
  Year 2017 Publication International Journal of Epidemiology Abbreviated Journal Int J Epidemiol  
  Volume 46 Issue 5 Pages 1573-1581  
  Keywords Bacteraemia; alcohol drinking; exercise; obesity; sepsis; smoking  
  Abstract Background: Bloodstream infections (BSI) cause considerable morbidity and mortality, and primary prevention should be a priority. Lifestyle factors are of particular interest since they represent a modifiable target. Methods: We conducted a prospective cohort study among participants in the population-based Norwegian HUNT2 Survey, where 64 027 participants were followed from 1995-97 through 2011 by linkage to prospectively recorded information on BSI at local and regional hospitals. The exposures were: baseline body mass index (BMI) measurements; and self-reported smoking habits, leisure time physical activity and alcohol intake. The outcomes were hazard ratios (HR) of BSI and BSI mortality. Results: During 810 453 person-years and median follow-up of 14.8 years, 1844 (2.9%) participants experienced at least one BSI and 396 (0.62%) died from BSI. Compared with normal weight participants (BMI 18.5-24.9 kg/m2), the age- and sex-adjusted risk of a first-time BSI was 31% [95% confidence interval (CI) 14-51%] higher at BMI 30.0-34.9 kg/m2, 87% (95% CI 50-135%) higher at BMI 35.0-39.9 kg/m2 and 210% (95% CI 117-341%) higher at BMI >/= 40.0 kg/m2. The risk of BSI mortality was similarly increased. Compared with never-smokers, current smokers had 51% (95% CI 34-70%) and 75% (95% CI 34-129%) higher risks of BSI and BSI mortality, respectively. Physically inactive participants had 71% (95% CI 42-107%) and 108% (95% CI 37-216%) higher risks of BSI and BSI mortality, respectively, compared with the most physically active. Conclusions: Obesity, smoking and physical inactivity carry increased risk of BSI and BSI mortality.

  Title Epidemiology and outcome of Staphylococcus aureus bloodstream infection and sepsis in a Norwegian county 1996-2011: an observational study Type Journal Article

  Abstract BACKGROUND: Staphylococcus aureus is one of the most common and lethal causes of bloodstream infection and the incidence is increasing. We carried out a prospective observational study of patients with Staphylococcus aureus bloodstream infection and sepsis in Nord-Trondelag county in Norway from 1996-2011. The main outcome of interest was all-cause mortality within 30 and 90 days. METHODS: Positive blood cultures were registered prospectively by the microbiology laboratory and clinical variables were retrospectively registered from patients' hospital records. The severity of sepsis was assigned according to the 2001 International Sepsis Definition Conference criteria. The association between clinical characteristics and mortality was studied using logistic regression analysis, and adjusted 30- and 90-day mortality risks were estimated. RESULTS: Among 373 patients, the median age was 74 years and 60.3% were male. 0.8% of the patients were diagnosed with MRSA. 29.8% of the patients developed severe sepsis and 12.9% developed septic shock. The all-cause mortality was 14.5%, 27.3% and 36.2% at 7, 30 and 90 days, respectively. Compared to patients with sepsis without organ failure (Mortality risk 13.3%, 95% CI 7.5-16.3%), the 30-day mortality risk was 3-fold higher among those with severe sepsis (39.9%, 95% CI 29.5-48.5%) and more than 4-fold higher for those with septic shock (57.3%, 95% CI 42.5-72.2%). The 30-day all-cause mortality varied by focus of infection, with the highest 30-day mortality risk among those with a pulmonary focus (42.4%, 95% CI 26.0-58.5%) and unknown focus of infection (38.7%, 95% CI 27.5-48.2%). The mortality risk did not differ between the first and second halves of the study period with a 30-day mortality risk of 27.3%, (95% CI 18.1-33.1%) for 1996-2003 versus 27.4% (95% CI 19.4-31.4%) for 2004-2011. The same pattern was seen for 90-day mortality risk. CONCLUSION: Staphylococcus aureus bloodstream infection carries a high case fatality rate, especially among those with severe sepsis and septic shock and among those with a pulmonary or unknown focus of infection. There was no decrease in 30- or 90-day mortality risk during the study period. This underscores the importance of continuing surveillance and efforts to improve the outcome of this serious disease.
