Rare Diseases Obscured by Shadows of ‘Popular’ Ills: Op-Ed
May 19, 2013
Laurie Edwards, lecturer in health and science writing at Northeastern University and author of In the Kingdom of the Sick: A Social History of Chronic Illness in America, contributed this article to LiveScience’s Expert Voices: Op-Ed & Insights.
After a lifetime of infections, hospitalizations and surgeries, a set of lab results changed everything for me. When I was 23, biopsies of my cilia (the tiny structures that line the respiratory tract) confirmed that I had a genetic respiratory disease called primary ciliary dyskinesia, or PCD. In patients with PCD, the cilia don’t beat properly, so clearing secretions is more difficult and infections and decreased oxygenation are common.
Haven’t heard of PCD? That’s no surprise; even when I’m in the hospital, I sometimes have to both spell and define it for health care professionals who don’t see it often, if ever. About 400 patients have been correctly diagnosed with PCD, though an estimated 25,000 Americans are suspected to have it.
Getting the correct diagnosis meant my label finally reflected my actual experiences of illness. Without proper treatment, the more advanced my disease became and the more disruptive my symptoms were. While the disease-specific details may differ, long diagnostic journeys are an unfortunate but inevitable reality for rare disease patients. Research suggests we wait an average of seven years to receive diagnoses.
All told, nearly 7,000 rare diseases affect some 30 million Americans, and eighty percent of them are genetic. Rare, or orphan, diseases are those that affect fewer than 200,000 patients, so there are many of us spread out across relatively small population pools. If doctors and nurses don’t always know what I have and what it means, you can imagine the blank stares I get in public or the sideways glances when people hear my “productive” cough.
Our culture celebrates cause-related marketing of popular diseases through charity events, national awareness months and consumer products. Rare disease patients are simply not going to see the type of corporate sponsorships and marketing in the name of awareness and research for cures that patients with more common conditions receive.
We do have some tools at our disposal, however. This spring marks the 13th anniversary of the Orphan Drug Act (ODA), legislation that provides necessary financial incentives for companies developing treatments for rare disease populations. Consider this: the National Organization for Rare Disorders (NORD) reports that in the decade prior to the ODA’s passage, only 10 drugs were developed. In the thirty years since, the FDA has approved 400 drugs for patient use, and an estimated 2,700 drugs are in the research pipeline.
