Living Dangerously With Cystic Fibrosis

Some with cystic fibrosis risk it all for human connection.

March 20, 2008 — -- For Kayla Small and Maggie Marcus, being roommates is truly living dangerously.

The two college-age friends have a rare disease that means sitting side by side in a car, sharing a glass or indulging in a bar-side Generation Y-style kiss could put their lives at risk.

Small and Marcus suffer from cystic fibrosis, a genetic disease that affects about 1 in 2,500 white Americans. Other races can be affected, but the majority of cases are found among those of European descent.

CF is characterized by extremely thick mucus that clogs the lungs and digestive tract, causing respiratory and digestive problems.

The viscous sputum can make breathing difficult, but it's the ideal environment for bacteria of all kinds to thrive and form large antibiotic-resistant colonies.

Healthy people don't get sick when exposed to the bacteria of a person with CF. Trouble starts when bacteria is passed from one CF sufferer to another, and the consequences can be deadly.

CF patients generally start off with comparatively mild infections like staph, but as the disease progresses, the strains that take root become progressively more virulent.

Even with regular checkups, one can never be absolutely sure what kind of bacteria is growing at a given moment, and if a person with a particularly vicious bacteria passes it to someone who doesn't have it yet, he or she can inadvertently quicken the other's decline.

The bacteria of concern to CF patients are easily contracted, so doctors advise patients to keep a minimum safe distance of three feet between each other at all times.

"It's a struggle," said Clement Ren, director of the Cystic Fibrosis Center at the University of Rochester. "You want to provide guidelines that work but are not unreasonable. You can't put everyone in spacesuits."

Yet Small, a published writer and a Columbia University graduate, subscribes to a personal philosophy that values intimacy with others who share her experience above all else -- even if it could mean she will get sicker faster.

Bill Taub, a clinical social worker at Duke University Cystic Fibrosis Center, estimates that about 10 percent of CF patients he has worked with have expressed similar feelings.
