Well, despite a few minor setbacks, I still managed to end the year with883 miles walked. A drop of almost 400 miles from my best walking year back in 2006, but nonetheless, still impressive when you consider what I have to work with.

Overall, my basic walking routine really hasn’t changed that much, I’m still out there walking at least 3 days a week when my lungs are behaving, and I try to hit the gym up at least once a week. I think the reason I was lagging behind in 2009, was that I was incarcerated 3 times (exacerbations and hospitalizations can really put a damper on things). That, plus I only completed 3 training cycles for the year, instead of the usual 4. One was for a full marathon ( Boston) and the other two for half marathons (ET midnight and San Rock&Roll). Those training cycles can really pile on the extra miles. Training for a full marathon for example, can easily add an additional 300 miles to the count.

I hate to admit it, but my lungs are finally starting to impact my ability to exercise and to walk long distances. It used to be that I would get 10-15 days of decent breathing in between flare-ups, even when I was training for marathons. Now it seems that every walk or gym workout that I do leaves me severely short of breath… sometimes for days. I’m not sure how much longer I’ll be able to keep this up.

Having said that, my goal for 2010 remains unchanged. I want to complete one more full marathon ( hopefully Boston) and Id also like to pass the 5,000 mile mark with my walking. After that, I’m definitely going to slow down.

And speaking of mileage; My legs, feet and lungs aren’t the only things that are suffering from wear and tear…. Check out my shoes!

[This is what the sole of my walking shoes look like after just 200 miles.]

In 2009, I went through 3 pairs of these Asics Hyperspeed 2s racing flats. Weighing only 158 grams (without the insoles) and with a low profile heel, they make excellent racewalking shoes. Unfortunately, since they’re made for speed and not distance, they wear out really fast. It’s also hard to find them now, since they’re not making them anymore.

For 2010 I’m going to try out the replacement model (the Hyperspeed 3) They’re pretty much the same shoe, though the new ones don’t seem to cup my heel as well.

No longer just reserved for severe pain control or to relieve end of life suffering, today a growing number of people with severe lung disease are using opiate medications to help quell their severe dyspnea . Well, you can now add to that list, a certain quirky little asthmatic marathon walker, by the name of Stephen.

The decision to write a post about the use of opiates to treat my breathlessness, was a tough one for me. As a responsible blogger, I always worry about the possibility of sending the wrong message, especially when it comes to the use of certain treatments and/or medications. Let me be clear in stating, that I don’t advocate the use of opiates for asthmatics in general… the risk of respiratory depression is just too high. There are however, a small percentage of people who’s obstructive lung disease is so advanced, that nothing else works in quelling their breathlessness. Though opiates should only be used as a last resort in treating dyspnea, they do offer a degree of welcome symptom relief for people like me, so I think their use is important to talk about.

For the past year Ive taking short acting opiates ( ie hydrocodone (Vicodin)and sometimes Dilaudid or Fentanyl) on an as-needed basis for bouts of prolonged moderate level breathlessness. When I say breathlessness, I’m not referring to the sudden shortness of breath that develops from acute bronchospasm or chest tightening you experience during an asthma flare. Rather, I’m talking about the type of breathlessness that’s usually associated with air-trapping and chronically low lung function. There’s a huge difference, and thankfully ,most asthmatics will never experience this second category.

Starting next month however, they (my palliative care docs), wanna put me on a 30 day trial of continuous low dose methadone (Yes, the heroin withdrawal drug). They believe, that having a constant level of opiates in the bloodstream, is more effective in relieving dyspnea, and is better tolerated, than the shorter acting compounded drugs like vicodin (vicodin has tylenol in it). My biggest concern about taking methadone or any of these morphine-like drugs, is how they will effect my ability to exercise. The experts claim that it might actually improve my exercise tolerance, because I wont “feel” as breathless. We’ll see about that.

Although physicians want to do all they can to help relieve dyspnea in their patients, fear of respiratory depression and criticism by colleagues has discouraged them from using opiates, even in treating those with end-stage disease. Thankfully, that attitude is slowly beginning to change. Opioids are very effective in relieving dyspnea, although the exact mechanism is not understood. Contrary to common belief, this effect does not result through inhibition of respiratory drive. Relief from the “work of breathing” is a function of steady-state opioid levels, much like steady-state opioid levels relieve pain. Inhibition of respiratory drive results primarily from rising opioid serum levels. Studies have demonstrated significant relief of dyspnea from opioids without significant effects on ventilation or pCO2 levels in common therapeutic doses.

For those of you who aren’t quite familiar the terminology, “dyspnea” is the subjective sensation of breathlessness or difficulty in breathing. It’s basically the experience of shortness of breath. Much like physical pain, we all perceive breathing discomfort differently. The way you perceive shortness of breath is probably different than the way I perceive it, and visa versa. Some of us have a higher tolerance for respiratory discomfort , and some lower. A million things can cause dyspnea, including chemical ,neurological and psychological abnormalities, but it’s usually a result of severe lung or heart problems. Dyspnea can me mild or severe. It can be acute ( abrupt ) or chronic ( long standing). Dyspnea is the main cause of suffering in lung disease patients, and is one of the top reasons why people seek emergency room care. Whatever the cause, dyspnea can be difficult to treat and can make your life miserable.

Why did they put ME on opiates in the first place? After all, I’m just a bad asthmatic , right?
Well, basically because we’ve tried everything else.
My lungs are so messed up , that even when my asthma is not flaring, I’m still short of breath. In fact, I’m pretty much short of breath to some degree … all the time. Because I’ve been this way for so long, for the most part it doesn’t bother me that much ….I’m used to it. But, there are other times when my dyspnea , for whatever reason, gets so out of control and so intense, that it becomes overwhelming and unbearable. Left unchecked, the resulting stress, anxiety and increased work of breathing that can emerge from these bouts, can actually fuel a full blown asthma exacerbation, leading to an unwanted date with an endotracheal tube. I actively practice all the standard treatment strategies, including daily exercise and stress reduction therapy to better manage my dyspnea. And while these more traditional therapies have probably helped me live longer and cope better with my disease, they haven’t alleviated much of the actual suffering. It’s for this reason, and under the guidance of a palliative care specialist, that I choose to take opiate medications and sometimes ativan to manage my dyspnea on a regular basis now.

Welcome to Pittsburgh, Pennsylvania for the Severe Asthma Research Program

(I just noticed what it says on the pillow)

Well, the trip was a success and the project went off without a hitch. However, the results that emerged from some of the studies they did on me , are not so good.

First , the good news…..

I finally got to meet Dr. Sally Wenzel (up close and personal you might say, considering she analyzed my DNA and probed around inside my lungs). It’s difficult for me to find just the right adjectives to describe how I feel about her, so I’ll just say … I love this women! She’s like my pulmonary physician soul mate. I admire her, not only because she’s an awesome Pulmonologist and research scientist, but mainly because of her fiery personality and the passion she has in trying to understand asthmatics and what makes us tick. And get this….she’s a good listener too! She actually cares enough about what you have to say, that she takes the time to listen. Imagine that.

I think Sally (Dr Wenzel) probably knows more about asthma pathology and the personalities of asthmatics in general, than any non-asthmatic person Ive ever met. It’s absolutely uncanny the things she knows about our disease and how we behave and live. She understands things about asthmatics that they don’t teach you in medical school. Things that you would only know by interviewing thousands of us and immersing yourself in the severe asthma culture. I could spend literally days just talking with her about this subject. We seem to teach each other. I am so lucky that I was given the opportunity to hook up with her. I think we will be friends for a long time.

The accolades don’t stop with Dr Wenzel, there were dozens of other wonderful people involved in this study as well. Here are just a few that Id like to mention by name and position.

Erin———–SARP research coordinator extraordinaire.
Cathrine RN—-Dr Wenzel’s assistant and other right hand
Mat tech——Very cool PFT tech.
Celo tech—–Just one of many super cool people on the bronch team
Trish RN——-A special Nurse. She actually called in on her day off to see how I was doing.
Lindsey RN—–Probably the sweetest Nurse Ive had the pleasure of meeting
Chuck RN——They don’t get better than this “young man”.
Rose RN——-Kind, Kind, Kind!
Michelle RN—-A Super Nurse.

To the above people , Id just like to say Thank You!
In all the years that Ive been in and out of various hospitals and clinics, Ive never come a cross a better team of compassionate and caring medical professionals like those associated with the SARP study, especially the people who took care of me in the Translational Research Care Unit at UMPC after my bronchoscopy. Kudo’s to you guys!

As for the SARP study itself, well, it’s probably the best coordinated and well thought out research experience Ive ever been a part of. With so many ancillary departments involved, like Nuclear Medicine, Pulmonary Functions and Diagnostics , it’s amazing how smooth the whole system runs. Everything is coordinated and timed down to the minute. In the bronchoscopy room, they actually had a group of lab personnel standing by in their running shoes, so that they could literally run the tissue samples over to the lab the moment they they were removed from my body. This method ensures that the samples will be ultra fresh. (I think).

Btw, if you’re not familiar with this part of the Country, the University of Pittsburgh and it’s affiliated medical schools ,hospitals and clinics, is massive in size. More like a small city, I counted at least 4 city blocks of medical buildings 2 and 3 deep. Some the size of mini skyscrapers, all connected through a series of enclosed pedestrian bridges. Pretty neat since it snows here in the winter.

Here’s an abbreviated version of my actual testing itinerary:

Wednesday Afternoon: Completed a ton questionnaires,did a verbal interview, and did pre&post bronchodilator spirometry, sputum induction attempt.
Thursday: Allergy skin testing (scratch test, not sub q), Full PFT ( lung volumes) pre&post bronchodilator.
Friday: Bronchoscopy prep, ( ie pre-medications and neb treatments), then nasal brushing, then the actual bronchoscopy with brushings and biopsy, but no lavage because of the potential side effects, more pfts
Friday Evening-Saturday,:Monitored in the hospital overnight.

As with any long distance trip , I didn’t eat or sleep very well and I’m totally worn out, but the effort of getting here to Pittsburgh to do this study was totally worth it. Definitively a positive experience and I would gladly return again if asked.

Look at all the blood they took from me

************************************************

Now for the not so good news….

Because this was the first time Ive ever had a bronchoscopy, it’s really the first time anyone has ever gotten a close-up look at the inside of my lungs. And what Dr Wenzel saw down there, wasn’t good. What she saw was lung anatomy that had undergone extensive remodeling. My airways appeared very scarred, stiff and fibrotic in nature…. seems my disease is much more advanced than previously thought. She actually found it quite amazing that I was still able to function as well as I do, let alone still alive. What was baffling to me, is that she couldn’t find any physical evidence of air-trapping or any of the other tell tale signs of COPD or emphysema that I often thought I had. It will be a few more weeks before they’ll have a final report, as they sent bits and pieces of my lung tissue and blood samples to various university labs for analysis, but suffice it to say, my long term survival isn’t looking too rosy right now.

( here’s a photo taken looking down into my left lower lung lobe)

They recommended that I seriously consider lung transplant surgery somewhere down the road. We all agreed that I’m not even close to that point right now, but that when the time comes, I shouldn’t procrastinate, as the waiting time for new lungs can take up to 3 years (asthmatics are usually put at the bottom of the list.) My one saving grace so far, is that my blood oxygenation is still relatively good(probably from all the aerobic exercise I do), and I’m still able to exercise, though that probably won’t be the case for very much longer.

Who knows, maybe someday I’ll be able to RUN the Boston marathon someday… instead of walking it!

Update as of 12-15-2009: Results from the computerized quantitative lung scans, did indeed show significant air trapping.

……………….Try saying that 5 times really fast.

Before reading this post, you might find it useful to read the first two of paragraphs in the “My Asthma” section of my blog. This will give you a little background as to why my dyspnea (shortness of breath) is so difficult to manage. Along those same lines, Rick over at the Respiratory Therapy Cave, does a great job of explaining how asthma can sometimes turn into COPD.

***************************

On Thursday I had my first appointment at this new service called “Symptom Management” . The clinic is basically an extension of the Palliative Care dept over at the UCSF Mt Zion campus. Rather than end-of-life care, this particular specialty focuses on treating the symptoms that cause suffering, i.e. breathing problems, pain, fatigue, stress, etc, regardless of the prognosis. I was referred there for my chronic and worsening dyspnea. Don’t get me wrong, I’m not giving up on traditional asthma care, but at the same time, I don’t want to fool myself. I know that this disease will eventually kill me . In the meantime I wanna stay, not only as physically active as possible, but ALSO as comfortable as possible. Which for me means breathing easier.

Most of my dyspnea (the sensation of breathlessness), stems from a condition called air-trapping. Pretty much the hallmark of obstructive lung diseases ( COPD, emyphysema and sometimes severe asthma), air- trapping occurs when airway obstruction due to chronic inflammation and/or loss of elasticity, causes air to become trapped in the lungs during exhalation. In other words…. I can’t exhale completely!
For an example of what air-trapping feels like. Take a full normal breath in, then try to exhale it out through a tiny straw (something like a coffee stirrer). See how long you can keep that up. You now have a sense of just how hard the work of breathing becomes for someone who has air-trapping . This is what my breathing feels like on a daily basis.

Things get even worse when my airways start getting twitchy, because then, in addition to the air-trapping symptoms, I also have to deal with my smaller airways closing up (bronchospasm). Having both of these 2 distinct symptoms at the same time becomes very troublesome, because it’s often difficult to tell which is causing which. Dyspnea associated with air trapping can most definitely make you feel uncomfortable, but the dyspnea that is caused by sudden or severe bronchospasm, can be potentially fatal.
In any case, the bottom line , is that dyspnea causes a lot of suffering and can make your life absolutely miserable.

For the past few years Ive been involved in several pulmonary rehab classes and research studies where they show you different techniques to help control your dyspnea. Some of what they teach helps, but most of these classes are geared towards people with COPD and Emphysema where having reactive airways ( ie bronchospasm) is usually not an issue. There are very few resources out there specifically designed to help chronic severe asthmatics deal with the complexities of the disease and type of breathlessness they experience. The only thing that’s really helped me so far, is a combination of relaxation techniques, anti-anxiety meds ( ativan) and mild opiates.

So anyways back to Thursday’s appt,

The symptom management doctor (who was really cool by the way) and I, both agreed that while my disease is pretty severe, that my quality of life is still quite good and that I should continue on with my current asthma action plan…even if it calls for future intubations! As far as my dyspnea goes, he recommended that I increase my vicodin dose to at least 4 times a day for better nighttime coverage. If that doesn’t work, he wants to try me on methadone ( yup, the drug heroin addicts use when detoxing ). I told him I would think about it, but I also made it clear that I didn’t want to take any medications that would effect my ability to exercise.
We also discussed “advance directives” and what would I want done ( or not done) , if I became critically ill and not able to communicate. For me this is mostly as issue of how long I would want to be on a ventilator, if there was no hope of recovering.

Im glad I went to this appointment. I think I came away a little less apprehensive about the whole issue of palliative care and what it implies. Anything that helps reduce the suffering that goes along with chronic disease ,is certainly worth considering as a treatment option.

In part two, I’ll talk about the impact that dyspnea and air-trapping have on my ability to exercise. For me, that’s the real dilemma.

Ever notice the time stamp on many of my blog entries? I usually compose and publish them in the early morning hours…sometimes way before dawn. You know why? Because I’m usually awake at 3 or 4 in the morning. And why am I up that early? Because Ive usually had a bad night of breathing and have to get out of bed just so I can breath.

I lead a double life. A mild to moderate asthmatic by day and a severe one by night . Starting around 6pm everyday, almost like clockwork, it’s as if someone came along and turned my bad breathing switch to the “on” position. Out of the blue, my peak flows will drop by as much as 1/3 , and as the evening progresses, so will my breathing discomfort. By the time 9 pm rolls around, I’m usually so uncomfortable, that I’ll have to down a little Ativan just to take the edge off. The drug doesn’t do anything for your breathing per se, it works by mellowing you out to the point where you basically don’t give a s**t that you’re short of breath. If the ativan doesn’t cut it , sometimes I’ll call on the big boys for help….the opiates. I hate taking narcotics for my breathing, because while they sometimes help, they also have a lot of side effects and can be very addictive.

I don’t wanna wave any red flags or sound overly dramatic, but there are times, especially during the evening hours, that my breathing gets so uncomfortable, I just want it all to end. I try to remain as calm as possible and do all the things that you’re supposed to do when your dyspnea gets outta control, but most of these stress relieving techniques, rarely work for me when my lungs get extra tight. Instead, I’ll usually go outside and sit on the front porch where there’s sometimes a breeze, and just tough it out the best I can. It’s during times like this , when all I can think of….. is not wanting to suffer with this disease anymore. It changes my personality and puts me in foul angry mood.

So why the huge daytime- to- nighttime swings? At first I thought it might have something to do with the time of day that I take my asthma meds. But thats unlikely, because I divide all of my meds into equal doses throughout the day to ensure more uniform coverage. My doctors thought that maybe I was having some sort of obstructive sleep apnea thing , but my sleep studies all came back totally negative. Then there’s the exercise issue, could too much exercise during the day make me feel like crap at night? Possibly, but again, the findings aren’t consistent. On the weekends when I generally don’t exercise, I still have the same nighttime breathing problems that I do on the days where I do exercise…sometimes even worse.

A lot of people will read this , assume that my asthma is simply not well controlled , and will recommend that I increase my bronchodilator use and/or steroid intake. The problem is, I’m already on maximal dosages of everything! , except for steroids in pill form, which for me, is not an option. My primary care doc recently recommended that I start taking a mild opiate, like vicodin, just before bedtime to see if that would quell my dyspnea enough to catch some sleep. Unfortunately, vicodin wires me.

Whether it’s full on bronchospasm or just air-trapping that brings on this distress, these bouts happen with such regularity now, that I don’t look forward to nice relaxing evenings anymore. In fact, I dread them. And except for an occasional night time stroll to take my mind off it, you’ll never see me out in public after dark.

I found this interesting article in the Chest Journal about this very same phenomena, titled “The Diurnal Rhythm of Asthma“.

OK, We can’t always have cheerful posts. I try my best to poke fun and put a positive spin on all things asthma, but lets face it, this disease sucks and can really dampen your spirits. Next week I have an appt with the Palliative care dept at UCSF, to see if they have any NEW advice to offer me, in dealing with my chronic dyspnea.

In the interest of being a responsible blogger, I must point out, that the use of opiates to treat dyspnea is usually reserved for people with terminal or end stage disease. It’s primary use is to end suffering.  Many pulmonologists would strongly discourage their asthmatic patients from taking such drugs, as they can also dangerously slow your breathing.

In case you didn’t get a chance to read the SARP’s study on asthma titled “Lung Function in Adults with Stable but Severe asthma”, here’s a postcast where they interview Ronald Sorkness, a physiologist at the University of Wisconsin and the lead author of the study.

Dr Sorkness does a great job of explaining the basics of asthma as well as the research the SARP is doing, in trying to find out what makes the severe form of the disease different from the milder forms. This is the same SARP study that I will be participating in later this year. Listen here
