The H1N1 influenza pneumonia as early complication after heart transplantation--experience from the Dubrava University Hospital, Zagreb, Croatia.

In April 2009, a novel influenza A (H1N1) virus was initially detected, and only after two months World Health Organization declared pandemic, while virus became globally present. We report here a confirmed case of patient suffering from H1N1 influenza pneumonia in an early period after heart transplantation. Complications of influenza A and B include viral pneumonia, secondary bacterial pneumonia and possibly acute allograft rejection in the setting of weaning of immunosuppression.
