pediatric septic shock study 3 (infant; subclass A) / pediatric septic shock study 3 (infant)

Relative Expression (log2-ratio):2.1728745
Number of Samples:8 / 30
Experimental pediatric septic shock study 3 (infant; subclass A)
Whole blood samples obtained from infants (1 month – 1 year) with septic shock subclass A. The samples were obtained within 24 hours of admission to the pediatric intensive care unit. Two children did not survive. The subclass A was defined based on an empiric, discovery oriented expression filter and unsupervised hierarchical clustering. Patients in subclass A (when all age groups were pooled) had a significantly higher illness severity level (PRISM III score = 20.5, intra-quartile range (IQR) 12.5 – 32.5), a greater degree of organ failure – maximum number of organ failures 3 (IQR 3 - 4), and a higher mortality rate, a significantly higher incidence of documented Gram-positive bacterial infection and were significantly younger compared with other subclasses.
Control pediatric septic shock study 3 (infant)
Whole blood obtained from infants (1 month – 1 year) with septic shock. The samples were obtained within 24 hours of admission to the pediatric intensive care unit (day 1). Five children did not survive.
