Brazilian researchers have found three distinct patterns of lung damage in patients who died of the H1N1 pandemic flu.

They also found evidence of a so-called “cytokine storm,” a runaway immune response associated with the lung damage, according to Thais Mauad, MD, PhD, of Sao Paulo University Medical School, and colleagues.

The findings come from the first autopsy series of patients who succumbed to the pandemic influenza strain, Mauad and colleagues wrote in the Jan. 1 issue of the American Journal of Respiratory and Critical Care Medicine.
