- PURPOSEWe aimed to determine the incidence, risk factors and outcome of acute kidney injury (AKI) in Finnish ICUs.METHODSThis prospective, observational, multi-centre study comprised adult emergency admissions and elective patients whose stay exceeded 24 h during a 5-month period in 17 Finnish ICUs. We defined AKI first by the Acute Kidney Injury Network (AKIN) criteria supplemented with a baseline creatinine and second with the Kidney Disease: Improving Global Outcomes (KDIGO) criteria. We screened the patients' AKI status and risk factors for up to 5 days.RESULTSWe included 2,901 patients. The incidence (95 % confidence interval) of AKI was 39.3 % (37.5-41.1 %). The incidence was 17.2 % (15.8-18.6 %) for stage 1, 8.0 % (7.0-9.0 %) for stage 2 and 14.1 % (12.8-15.4 %) for stage 3 AKI. Of the 2,901 patients 296 [10.2 % (9.1-11.3 %)] received renal replacement therapy. We received an identical classification with the new KDIGO criteria. The population-based incidence (95 % CI) of ICU-treated AKI was 746 (717-774) per million population per year (reference population: 3,671,143, i.e. 85 % of the Finnish adult population). In logistic regression, pre-ICU hypovolaemia, diuretics, colloids and chronic kidney disease were independent risk factors for AKI. Hospital mortality (95 % CI) for AKI patients was 25.6 % (23.0-28.2 %) and the 90-day mortality for AKI patients was 33.7 % (30.9-36.5 %). All AKIN stages were independently associated with 90-day mortality.CONCLUSIONSThe incidence of AKI in the critically ill in Finland was comparable to previous large multi-centre ICU studies. Hospital mortality (26 %) in AKI patients appeared comparable to or lower than in other studies.

- BACKGROUND: Urine neutrophil gelatinase-associated lipocalin (uNGAL) is increasingly used as a biomarker for acute kidney injury (AKI). However, the clinical value of uNGAL with respect to AKI, renal replacement therapy (RRT), or 90-day mortality in critically ill patients is unclear. Accordingly, we tested the hypothesis that uNGAL is a clinically relevant biomarker for these end points in a large, nonselected cohort of critically ill adult patients. METHODS: We prospectively obtained urine samples from 1042 adult patients admitted to 15 Finnish intensive care units. We analyzed 3 samples (on admission, at 12 hours, and at 24 hours) with NGAL ELISA Rapid Kits (BioPorto (R) Diagnostics, Gentofte, Denmark). We chose the highest uNGAL (uNGAL24) for statistical analyses. We calculated the areas under receiver operating characteristics curves (AUC) with 95% confidence intervals (95% CIs), the best cutoff points with the Youden index, positive likelihood ratios (LR+), continuous net reclassification improvement (NRI), and the integrated discrimination improvement (IDI). We performed sensitivity analyses excluding patients with AKI or RRT on day 1, sepsis, or with missing baseline serum creatinine concentration. RESULTS: In this study population, the AUG of uNGAL24 (95% CI) for development of AKI (defined by the Kidney Disease: Improving Global Outcomes [KDIGO] criteria) was 0.733(0.701-0.765), and the continuous NRI for AKI was 56.9%. For RRT, the AUG of uNGAL24 (95% CI) was 0.839 (0.797-0.880), and NRI 56.3%. For 90-day mortality, the AUG of uNGAL24 (95% CI) was 0.634 (0.593 to 0.675), and NRI 15.3%. The LR+ (95% CI) for RRT was 3.81 (3.26-4.47). CONCLUSION: In this study, we found that uNGAL associated well with the initiation of RRT but did not provide additional predictive value regarding AKI or 90-day mortality in critically ill patients.

- Background Food allergies can substantially burden patients and families by negatively affecting finances, social relationships, and personal perceptions of health. This study was performed under the Finnish Allergy Programme aimed at reducing avoidance diets to foods in schoolchildren by 50%. The main goal of this study was to investigate how many children could be freed from diet restrictions in a Finnish school district through a diagnostic algorithm including component-resolved diagnostics and food challenge. The secondary aim was to provide a crude estimate of the burden of the elimination food diets in the region, and the savings associated with the proposed intervention. Methods A total of 205 children on a food avoidance diet according to the school register because of food allergy were invited into the study. One hundred and fifty-seven children were interviewed, tested for IgE to extracts and allergen components and food challenged in respective order. Results After two years, 12 children still had an avoidance diet and three of them were treated successfully with sOTI; the rest suspended their avoidance diet (n = 134) or dropped out of the study (n = 11). The cost of the elimination diets was estimated in 172 700euro per year at start and 13 200euro per year at the end of the study; total savings were 128 400euro yearly. Conclusions The results demonstrate a 65% reduction of avoidance diets to foods in school-aged children, exceeding the 50% aim of the Finnish Allergy Programme. Therefore, it is possible to actively reduce the number of food allergy diagnoses that remain unmonitored in the society through a tailored diagnostic work-up.
