New Nutritional Guidelines for CF

For those of you interested in the new nutritional guidelines which were launched at this year’s Australian CF conference you can download a copy of them here. [This is the final draft but final copy not yet available online].

You’ll see these new guidelines not only promote a healthier more wholistic diet than previous CF recommendations. Moving away from any fat and sugar to make the calories add up  – to an emphasis on good fats and heart health where possible. The guidelines also touch on vitamins and supplements – namely glutathione, probiotics to name a few emerging areas which have not been formally addressed before.

What is the optimal anti-pseudomonal treatment when Pa is first isolated?

Pseudomonas aeruginosa causes lung infection and chronic lung infection is still the leading cause of lung infection and morbidity in CF. So as a CF community we must be vigilant about:

  1. Infection control
  2. Surveillance
  3. Early diagnosis
  4. Early treatment

Whereas the median age for chronic infection used to be 5 years, its now around 25 years in the top US centres.

Of course the million dollar question (there are many withn pseudomonas but the one we’re most concerned with) is which is the most effective course of treatment for eradication?

While inhaled Tobramycin has been shown to transiently clear the pseudomonas from  the lower airways – it doesn’t clear the lungs of the inflammation which is a key factor in the disease progression and continues the cycle of damage.

Study # 1

In a study cited in this preso, patients were randomised to receive one of two aggressive approaches of 4 weeks inhaled Tobi vs 2 weeks of IV Tobi and Ceftazadine (which is what we do at our clinic) and then they had did a bronch wash of the lower airways (the gold standard to see what’s kicking about down there).

The results showed that there was a difference in the inflammatory markers but it appears that the conclusions drawn were that the results were not significant enough to balance out the feasability, costs and side effects of the systemic IV antibiotic treatment.

Study # 2

The next study compared the two different treatment methods in the US and the UK amongst asymptomatic children (ie. not sick but just positive culture)

Inhaled Tobramycin for 28 days (USA)

VS

Inhaled colistithemate + oral ciprofloxin for 3 months (UK)

After one year the groups had no significant differences in BMI, FEV1, pseudomonal-specific igg – none of the markers that we care about.

After 2 years, 10% of the patients had chronic pseudomonal infection in both groups.

Study # 3

Comparing two more treatment protocols:

Inhaled Tobramycin + oral ciprofloxin

VS

Inhaled colistithemate + oral ciprofloxin

Again this study resulted in no major difference in the eradication profile.

Study # 4

The Standford University team also looked at the timing approach for pseudomonal eradication protocols over a 5-10 year period with their own clinic.

Group # 1 – After a positive Pa culture, they received the initial 28 days inhaled Tobramycin followed by a cycle of treatment for the next 5-6 months (presumably month on, month off).

Group # 2 – Group # 1 – After a positive Pa culture, they received the initial 28 days inhaled Tobramycin followed by a second cycle of treatment if they continued to culture Pa in their swabs.

That group that received the “cycle of treatment” irrespective of whether they continued to test positive or negative for Pa following the initial infection.

Patients on the “cycle therapy” got their 5 rounds of antibiotic therapy post infection regardless of whether the sputum was clear or positive Pa after the initial treatment did not seem to be protected from exacerbations.

So what is the gold standard of care when it comes to Pa?

  1. Inhaled antibiotic therapy – Tobramycin twice daily for 28 days
  2. Against the use of an anti-pseudomonal drug to avoid infection
  3. Routine surveillance sputum cultures to test for pseudomonas before symptoms set in
  4. Positive pseudomonas cultures should be treated quickly (inside of 4 weeks)
  5. There is robust evidence that pseudomonas eradication treatment is effective but there is no definitive result to suggest that one method is superior to another.

2015 Australasian CF Conference

IMG_0611For those of you who couldn’t make it to the 2015 Australasian CF Conference we did our best to take some notes and capture some of the content for you.

Penny has taken some notes on the following topics:

  1. Transitioning with success
  2. Sexual health for adolescents with CF
  3. Transplants : The Work Up / What’s required
  4. Energy expenditure, hydration and nutrition in the active person with CF

You can download these here 11th Australasian CF conference 2015

Likewise I’ve taken pics of some of the key slides from the following presentations so feel free to download and have a read (more to follow):

Medicines for children with CF

Participate – Use your own knowledge to improve your childs health

I’ll post the remaining sessions as soon as I get a chance

A few notes from the latest CFRI conference in California

Screen Shot 2015-08-13 at 8.43.51 AMLast week the annual CFRI conference was held in Redwood City California. For those of you who are not familiar with CFRI, it’s a terrific organisation that funds cystic fibrosis research, provides educational and personal support, and spreads awareness of cystic fibrosis.

Their website hosts a bunch of terrific content from research paper, presentations and key learnings to events and links with other key CF networks. It’s well worth your while getting on there and having a look. They also held a pediatric conference earlier in the year which had some incredible content specifically related to pediatrics. Do yourself a favour and get onto that content when you have a moment, its positive, uplifting but really informative. You can find that here

Screen Shot 2015-08-13 at 8.44.09 AMI travelled to the most recent conference last week which was fantastic. About 200 people went, a combination of speakers that included CF doctors and program directors, a physiotherapist, a social worker, an infection control expert and CF nurse / clinic co-ordinator who has devoted her life to CF; plus about 150 CF parents.

I took a heap of notes so that I could share the content with you all. You can download my notes here.

CFRI summary notes

Please keep in mind that there was a mountain of info so I’ve done my best to try and record / remember as much as I could in each session but there may be some things missing. There’s a bit more to put down on paper but this is the majority of the sessions as I remember them.

If you have any questions please give me a shout at jen@ecooutdoor.com.au
