Rare lung diseases and disorders


Welcome Message

Welcome to this week’s ATS focus on rare lung diseases. Rare diseases are receiving increased interest in all fields of medicine because they help discover new genomic pathways that influence more common diseases. This week’s partner is the Hermansky-Pudlak Syndrome Network (HPS Network). To date, 9 genes have been discovered in families with this syndrome (HPS-1 to HPS-9) and yet a cure remains elusive. Therefore, the missions of education, improving diagnostic delay, access to knowledgeable physicians, and accelerated research that are so important to the HPS Network are common themes with all of the rare disease communities.

Cumulatively, rare diseases are estimated to be present in 10 percent of all individuals. These 6, 000-8, 000 diseases have a genetic cause 80 percent of the time. With the pressure to control the costs of U.S. health care, the ability for clinicians to test for and diagnose rare diseases will emerge as a problem. In response to this concern, the National Institute of Health is advancing the concept of an Undiagnosed Diseases Network that is modeled on a successful program within the intramural branches. Should everyone with an undiagnosed possible rare disease get a peripheral blood mononuclear cell gene array? In our own pulmonary community, are we making enough progress understanding the genomic phenotypes of our common airways, vascular and parenchymal lung diseases?

appellPlease take this opportunity to become knowledgeable about Hermansky-Pudlak syndrome. The tireless energy of the HPS Network staff and volunteers has made this disease known in the interstitial lung disease community. There is much online that allows individuals with albinism and lung disease to “discover” their own diagnosis. However, like most rare diseases there are many details that are important to understand. Are we adequately searching for partial cutaneous albinism and platelet disorders in our idiopathic pulmonary fibrosis (IPF) patients? The next step is the translation of what our pulmonary community knows to the primary care community. Thank you for visiting this week’s Public Advisory Roundtable focus.

The Hermansky-Pudlak Syndrome Network is a not-for-profit organization founded in 1993 and incorporated in 1995. It serves patients and their families struggling with HPS from around the world. The HPS Network is a major resource for education and support for both patients and professionals.

Confirmed Variant Creutzfeldt-Jakob Disease (variant CJD) Case in Texas
Posted: June 2, 2014
Laboratory tests have confirmed a diagnosis of variant CJD (a fatal brain disorder) in a patient who recently died in Texas. The confirmation was made when laboratory results from an autopsy of the patient’s brain tested positive for variant CJD.
First described in 1996 in the United Kingdom, variant CJD is a rare, degenerative, fatal brain disorder in humans. It is believed to be caused by consumption of products from cows with the disease bovine spongiform encephalopathy (BSE, or "mad cow" disease)

Stem Cell Hysteria

Just a little reality into the stem cell HIV story

Timothy Ray Brown, an HIV-positive American living in Germany, had leukemia and was undergoing chemotherapy, when he received a transplant of stem cells from a donor carrying a rare, inherited gene mutation that seems to make carriers virtually immune to HIV infection.
The transplant appeared to wipe out both diseases, giving hope to doctors, but Dr. Anthony Fauci, director of the National Institutes of Allergy and Infectious Diseases, who has been studying HIV/AIDS for almost 30 years, said while this is an interesting proof of concept, it’s absurdly impractical

And answer your question.
ATE most commonly affects middle-aged (5-7year) male domestic variety cats. (male:female ratio 2:1 – 3:1). Most affected cats are spayed or neutered, however, analysis has not identified sterilization or lack thereof as a significant risk factor.1-2 The vast majority of cats with ATE have clinical evidence of underlying cardiac disease, however, neoplasia, aortic surgery, infectious disease, sepsis, and foreign body have all been associated with this condition. On rare occasion, a predisposing condition is not identified. ATE is seen in approximately 10-20% of cats with underlying cardiac diseases and is associated with concurrent evidence of congestive heart failure (CHF) in greater than 50% of cases
