Last fall, the PCDF launched the "Move 4 a Cure" campaign designed to get folks moving while raising awareness and much needed funds for PCDF programs. As part of this campaign, the PCD community set a goal of $25,000 for our annual October Awareness month. Thanks to the dedicated efforts of our awesome PCD community, the group not only met, but surpassed that goal, collectively raising $26,000 for PCDF!

In total, fundraisers were held in 13 states from Alaska to Mississippi. Events included walks, runs, spinning competitions, basketball free throws, various home parties, crowd- funded online fundraisers and T-shirt sales. People of all ages participated in events. Three families sold over 500 PCD tee-shirts- that is 500 people wearing PCD conversation starters!

We were overwhelmed by the support and hard work of the PCD community and very grateful for an incerdibly supportive community.  Big or small- every event counts, every cent counts, every conversation counts. You made a difference!  Together will we continue to 'Move" towards a cure.


On behalf of the PCD Foundation Board,

Thank you for all of your hard work & efforts!

Dr. Knowles Interviewed about Rare Diseases

This is a very nice overview of history of accelerated interested in rare disease research.  Dr. Michael Knowles from UNC is quoted in reference to his role with the Genetic Disorders of Mucociliary Clearance Consortium (GDMCC, aka 'PCD study'):


Ciliary Ultrastructure: What Your Doctor Sees

Here are examples of ciliary ultrastructure analyzed from the biopsy samples taken to diagnose PCD.  To get these views, the cilia (which are microscopic) need to be sliced for cross-section. Cilia are long and thin (think blade of grass). The cross-section view would be like looking down at the inside of the grass blade after it's been cut.  


To enable cross-section slicing, the sample is preserved in a wax-like substance that hardens and tiny slices are prepared for analysis under the electron microscope. This microscope is orders of magnitude more sensitive than a regular microscope, but can still only magnify items that are 'electron dense.' We now know that certain defects (for instance, DNAH11 outer dynein arm defects) appear not to be electron dense, so they don't show up on biopsy.  We don't know how many other PCD genetic mutations may fall into this category, though, which is why the biopsy alone is not sufficient for ruling PCD out. Having a 'normal' biopsy does not necessarily mean you don't have PCD--just that you don't have PCD caused by a defect that shows up on biopsy. 

To give you an idea of the challenges faced by pathologists and doctors trying to analyze these biopsies, here is a slide showing normal ultrastructure (bottom left) and PCD with absence of dynein arms (bottom right). These slides represent the 'perfect world' of biopsy samples. They are clear, the defect is obvious and, if the defect was seen in many cilia, it would not be hard to make the call for PCD caused by absence of dynein arms. You will need to click on the link, as I could not figure out how to get the picture uploaded directly to this site:


Ciliary Ultrastructure: Normal and PCD


And here are four examples of what pathologists see in the 'real world.' 


Ciliary Ultrastructure: Abnormal


As you can see, what pathologists normally get to work with is far from ideal. The images are blurry and while these are  very defective looking cilia, the defects tend to be inconsistent within the same sample. The important point is that these ciliary samples all came from people without PCD. They represent a small sample of the temporary ciliary defects that can occur from having a respiratory infection or from exposure to an environment toxin. You can see why diagnosis of PCD via biopsy tends to be as much art as science at times. 



BESTCilia:European PCD Grant Kicks into High Gear!

The European Union is funding the Better Experimental Screening and Treatment for Primary Ciliary Dyskinesia (‘BESTCilia’) initiative, an international collaboration aimed at creating standards for diagnosis and care that can be implemented across Europe and shared with collaborators in other countries.

This initiative is headed by Dr. Heymut Omran from Muenster, Germany and includes partners from across Europe, the UK and North America, including experts from the UK, the US, Denmark, the Netherlands, Cyprus, Greece, Poland and Switzerland .  Dr. Margaret Leigh, a PCD expert from the University of North Carolina, Chapel Hill, is representing US interests.   Additionally, patient advocacy groups, including the US PCD Foundation and groups from the UK, Germany and Switzerland are active participants in this grant initiative and provide input from the patient perspective related to needs and priorities of the international PCD patient community.

On March 1 and 2nd, Michele Manion from the US PCD Foundation attended the inaugural ‘Kick-off’ Meeting for the BESTCilia group in Limassol, Cyprus.  The BESTCilia grant is divided into seven ‘work packages,’ each with specific aims related to the broad goal of improving screening and treatment for PCD.  The PCDF is participating in three packages:

1. International PCD patient registry (development and implementation)

2. Health-related quality of life tool (development and validation)

3. Dissemination of information related to BESTcilia activities

Other work packages include an ambitious effort to collect and organize anonymous data already captured at PCD centers around the world and to launch the first-ever clinical trial of a drug (azithromycin) in PCD!

It is exciting to see the goals of individual groups coalesce in an international effort on behalf of PCD.  Given that each country has a relatively small patient population, the only way we can have the numbers needed to effectively power future clinical trials is to cooperate and we are fortunate in having such fantastic international partners as we move PCD science forward!
