Pope's problems aggravated by Parkinson's

The pope’s breathing problems are not a routine complication of the flu but are worsened by his Parkinson’s disease, several doctors said.

“A normal person might get some tightness or constriction in the throat” but would not suffer spasms of the trachea, or windpipe, severe enough to necessitate hospital treatment, said Dr Jaimie Henderson, a Parkinson’s expert at Stanford University School of Medicine in the US.

The flu itself is cause enough for concern, especially considering John Paul is 84 and frail. Flu and its main complication, pneumonia, kill nearly 40,000 elderly people in the United States each year. It is not known whether the pope had a flu jab or the pneumonia vaccine.

“His age and the fact he has Parkinson’s disease puts him at higher risk of not recovering from this,” said Dr. Gary Leo of the Regional Parkinson’s Disease Centre at Aurora-Sinai Medical Centre in Milwaukee.

“There are a lot of different processes that can make Parkinson’s worse, and infections are one of them.”

The pope’s heart function was said to be normal, but he has been increasingly frail from Parkinson’s, an incurable neurological disease that gets progressively worse and weakens muscles that control breathing, swallowing and other movement.

“His breathing may not be as full because of the Parkinson’s. The chest wall doesn’t move as well. It may complicate his recovery,” Leo said.

The disease puts him at high risk of potentially fatal complications, especially infections.

“There must be a suspicion that he’s developed a complicating pneumonia,” said Dr William Schaffner, an infectious diseases expert at Vanderbilt University. That would be an “ominous” sign for his health, Schaffner said.

A key sign in the coming days, doctors said, will be whether the pope requires a plastic breathing tube down his windpipe to help him breathe. That would require sedation and usually a machine to take over breathing for him until he is strong enough to breathe on his own again.
