Researchers find new patterns in H1N1 deaths
Date:12/23/2009

Brazilian researchers have performed the first-ever autopsy study to examine the precise causes of death in victims of the H1N1 swine flu.

"The lack of information on the pathophysiology of this novel disease is a limitation that prevents better clinical management and hinders the development of a therapeutic strategy," said lead author, Thais Mauad, M.D., Ph.D., associate professor of the Department of Pathology at So Paulo University, in Brazil.

The results of their study will be published in the January 1 issue of the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.

The researchers examined 21 patients who had died in So Paulo with confirmed H1N1 infection in July and August, 2009. Most were between the ages of 30 and 59. They found that three-quarters (76 percent) of the patients had underlying medical conditions such as heart disease or cancer, but there was no clear complicating medical condition in the remaining quarter. All presented a progressive and rapidly fatal form of the disease.

While previous data has shown that most patients with a non-fatal infection have fever, cough and achiness (myalgia), Dr. Mauad noted that "most patients with a fatal form of the disease presented with difficulty breathing (dyspnea), with fever and myalgia being less frequently present."

All patients died of severe acute lung injury, but there were three distinct patterns of the damage to their lungs, indicating that the infection killed in distinct ways. "All patients have a picture of acute lung injury," said Dr. Mauad. "In some patients this is the predominant pattern; in others, acute lung injury is associated with necrotizing bronchiolitis (NB); and in others there is a hemorrhagic pattern."

"Patients with NB are more likely to have a bacterial co-infection. Patients with heart disease and cancer are more likely to have a hemorrhagic condition in their lungs. It is
