Karen - 20 Oct 2005 01:19 GMT In asking the vet to replace the pred, she is suggesting aminophylline. It is two times a day. Has anyone here tried that? They seem resistant to trying the aerokat for some reason. I will be talking to her more in detail next week. Poor Pearl had blood drawn today, but the blood machine wasn't working right and the person making the appt. didn't tell me she should fast, so it was pretty much a wasted effort. Poor Pearl.

The medicine is similar (or the same as) to theophyllin. Related to caffeine. It kept me alive for years.

Aminophylline is injectable only, and is considered obsolete in humans. Theophylline is still used orally, but is definitely a third-line drug, with a narrow range between therapeutic and toxic levels.
It depends, of course, how practical inhalers are. Again, do remember that I'm extrapolating from human medicine. Pretty much the mainstay of prevention is a mixed inhaled corticosteroid with a long-acting beta-agonist such as salmeterol. Other classes of inhalable drug include cromolin and neocromil (preventive), short-acting beta-agonists like albuterol (rescue/intervention), and anticholinergics such as ipratropium (inbetween preventive and interventional).

She definitely said aminophylline. And definitely oral (although I know it is also injectible and used in crisis situations).

It can help with symptoms, but does not reduce the underlying inflammation. You need some kind of steroid for that, which is what the prednisone/prednisolone is. I can't see *replacing* an anti-inflammatory with a bronchodilator. Often both are prescribed.
Do you have any idea why your vet is resistant to inhaled therapy? Just lack of familiarity?
Poor Pearl, indeed. Purrs for a better vet visit next time.

One thing about Pearl is I do not think she is as bad as many. She doesn't have daily problems and never did. Maybe twice weekly at the worst times (except that one day when I took her in) with big stretches (probably "off season"). I just don't know what to do. I will definitely address the concern about it being damaging without the steroid.

They seem resistant [quoted text clipped - 10 lines] > *replacing* an anti-inflammatory with a bronchodilator. Often > both are prescribed. I agree. The mainstay of modern asthma therapy is preventing or mitigating the inflammation, not bronchodilation. Drawing from human medicine, there are complex ways to deal with predisone toxicity, such as supplementing with low-dose methotrexate. It's possible neocromil or cromolyn can replace corticosteroids, but definitely not a given. Cromolyns are preventive, but not strictly anti-inflammatory. Instead, they raise the sensitivity that causes inflammation. I wouldn't want to stop corticosteroids and THEN try them, but I'd add them to the corticosteroids and see if there was improvement.
Cromolyns, AFAIK, must be inhaled.

Well, the new medicine they prescribed for Nikki just before she died was theophylline; I don't know how closely related it is to aminophylline. Of course, I'll never know if it was the meds or something else - e.g. a brain tumour - that gave her the fit that she never recovered from.

I don't want to project my sense of guilt on you, but I just have to say I wish so much that I'd insisted on some sort of inhaled meds, though my vet at the time honestly stated she didn't know much about them for cats. But then hindsight is always twenty-twenty, isn't it.

Karen, I've read the entire thread and think you might be right about your vet just not being knowledgeable about inhaled meds, thus not wanting to go that route. It would seem that as the client you and Pearl have the right to insist on the route of medication. We know that aminophylline is a bronchodilator which indicates your vet is currently wanting to treat the symptoms only. Has Pearl recently had a steroid shot that might be controlling the inflammation? My thoughts are that the vet knows she's given Pearl a steroid and is now wanting to give her something to control coughing. She isn't comfortable prescribing inhaled meds so she's going with the aminophylline. When I brought Sam home from the emergency vet he was on Terbutaline which is another oral bronchodilator. I was given a prescription for Albuterol but told not to use it until he had finished taking the oral terbutaline...emphasis on do not give both at the same time. Sam had been given a steroid injection several weeks before and they did not want to give him another injection but wanted me to go ahead and begin with the Flovent as soon as I could. Both the emergency vet and my regular vet were well educated about inhaled meds so no other options were ever discussed. I was directed to the fritzthebrave web site for additional information and fortunately Sam never gave me any trouble about taking inhaled meds. Now - 10 months later - when he sees me shaking the canister of Flovent he runs to the cat tree, sits on the platform and waits for me.
I think if I were you, knowing what you know, that I would make an appointment with the vet and show up without Pearl and just discuss what you know about inhaled meds and the fact that you want Pearl to receive the safest medical treatment possible. Maybe ease her mind by having her give you a prescription for the terbutaline in the event you can't get Pearl to adapt to the mask right away. That would give you a way to treat an attack. Print out the protocol and pictures found on the fritzthebrave web site so that she can read it for herself. Order an aerokat device which takes several days to arrive and hopefully by the time you have that she will have read the material you gave her and you'll be ready to treat Pearl.
Sam started with 2 puffs of 220 mg Flovent, twice a day. He has finally reached a point where he can have 2 puffs once a day. I suspect when the weather changes and I have to turn on the heat again he may have to go back to twice a day, although I have eliminated a lot of the triggers (most importantly, I don't smoke in the house any more).
I don't know if any of this information helps, but Sam is sending extra special purrs for Pearl, which I know will help ;)
If you'd like, I'll be happy to send an email to your vet telling her about Sam's case. He was in acute respiratory distress when we landed at the emergency vet. He was cyanotic and had a collapsed lung. He was in an oxygen cage for 48 hours and within a month of using the inhaled meds his condition was manageable. During that month he required fairly regular doses of Albuterol but now I haven't given him Albuterol in 3 months!

Karen - 20 Oct 2005 21:06 GMT One thing about Pearl is I don't think her asthma is bad. At the most she has coughed say three times a week (until The day I took her to emergency, when she did have 5 bad attacks. She was definitely uncomfortable and growly.,) not daily, like some and her worst cough attacks did not include open mouth breathing. But when she has them it looks *exactly* like that video on Fritz the Brave.
The emergency vet really thought it was asthma but I think my vet got distracted from that whole issue when we found the enlarged heart. However, Pearl has been doing this since I got her 3 years ago and the xray we got of her 2.5 years ago shows a normal heart so I truly believe this was pre heart trouble. I wonder if this vet is not resisting for that reason too.
At any rate, I was "practicing" today to see how Pearl would do with something on her face and I can put an empty toilet paper roll over her nose and mouth and she is not real freaked out or anything. Pearl is not heavily "noise conscious". She has let me vacuum her body. I think it would actually be easier on her than pilling because she has SUCH a gag reflex.
I am definitely going to wait on the aminophylline and just be very forthwright that everything I have read suggests aminophylline is not good without a steroid used in conjunction with it and using the steroid is what I want to get away from! She takes oral pred, 1/2 every other day, but I actually haven't given her one now since Saturday.
After her last attack, which happened when I turned off the a/c and had the deck door open (and also had too old of filters in our HEPA room air filter), I started her up on pred 1/2 twice a day and then tapered down again. I also turned back on the a/c and got new filters. Now it is getting cold again, and I really have to turn off the a/c. So, I have a call in to talk to my vet. Unfortunately, instead of Sugar's vet, Pearl has ended up with the younger feline vet and I do think that plays into this. Thanks for you detailed post. I am lucky as I do not think Pearl is anywhere near as bad as Sam or other kitties. I don't want her getting worse either!

If your vet is confident with a diagnosis of asthma then get agreement on the severity of it, mild, moderate or severe? This will guide medication choices and prescription. Dr. Phil Padrid's inhaled medication protocol may be found at http://www.fritzthebrave.com/meds/inhaled_protocol.pdf
In general what has been said on this forum is right on: for moderate and severe asthmatics (frequent symptoms) then they should be on a regularly-provided antiinflammatory first, with help from a bronchodilator second. For moderate and severe asthmatics, relying on a bronchodilator alone doesn't protect the cat from a serious attack when the bronchodilator wears off -- the anti-inflammatory provides a measure of protection/prevention of severe attacks.
Mild seasonal/infrequent asthmatics with nonthreatening symptoms may be better off without regular anti-inflammatory drugs.
In my lay opinion, three times a week and then emergency visits sounds to me like Pearl is squarely in the realm of a moderate to severe asthmatic -- very much like Fritz! Fritz has twice daily treatment with two puffs of 220mg Flovent, and recently has also been needing Combivent once/day (a mixture of Albuterol and Ipratropium). With this he is symptom free. I wish he didn't need any bronchodilators but he gets symptomatic and moody without them - although his symptoms are not life threatening. I wish he was doing better. The good news is with the Flovent his attacks are mild and easily halted with the bronchodilator.
By the way, Flovent *is* a steroid ("glucocorticosteroid") -- the difference is that it is applied directly to the smallest chambers of the lung tissues via fine aerosolization. While larger aerosol particles impact in the larger airways, and are swallowed and processed by the liver, they are pretty much nonreactive with internal organs so have no measurable systemic effect as compared to prednisone or dexamethasone (popular oral/injected steroids). This is why Flovent is 'safer' systemically.
The enlarged heart is definitely a complicating factor and will be important in treatment choices... I'm out of my league with that. The good news is that cardiac health is much better understood by vets, and you can help educate them a little bit with the pulmonary health options, right? :)
Keep up the dialogue with the vet and feel free to print out whatever you need from fritzthebrave.com. Let us know how Pearl does.

Karen - 20 Oct 2005 23:20 GMT Wow thanks SO much for responding. I will definitely keep everyone posted.Yes, I would say she is perhaps moderate (although I *do* believe seasonality has it's place with her as well.) I *know* smoke is a trigger so she is never exposed to that, she does sneeze if the deck door is open. She blows out through her nose like a "huffing" if she is upset by another cat (which I have never seen another cat do before. I can't tell if that is part of it, or just some idiosyncratic behaviour) and she occassionally gets a little bit of goopy eye when stressed. Well, I will certainly keep everyone posted. Thanks again :)
> Hi Karen, > [quoted text clipped - 44 lines] > > James Perkins, coauthor http://www.fritzthebrave.com james@loowit.net - 21 Oct 2005 00:31 GMT Karen and Pearl,
Kathryn adds: "Asthma is a life long condition. The inflammation is ever present. It can wax and wane and appear seasonal but we should not confuse human seasonal allergies with asthma (in cats or humans). The inflammation will become symptomatic (cat coughs or wheezes or is lethargic) when the invisible inflammation rises to that crisis stage. A cat with symptoms is a cat with undercontrolled asthma.
"A cat with known asthma who has not shown signs of it in a long time is a very well controlled asthmatic and one can be fooled into thinking they are "cured". We learned the hard way with Fritz and backed down on his medication.... and after a while, he began to cough again."
So we learned our lesson and just keep treating him. He is a happy cat now, and that's a relief to all of us.
When we first learned Fritz was asthmatic it was like a mysterious death sentence. We found that comprehensive information about the disease and its treatment was lacking on the Internet, and it would have made our lives and many others' much easier... so as we pieced together a much more hopeful outlook with Fritz, we had to try and organize and share what we have learned to ease the communal suffering! It has been so rewarding to see so many others also studying and passing along accurate/helpful information and to be a part of that. Pass it on...
Cheers, James
Karen - 21 Oct 2005 01:49 GMT > Karen and Pearl, > [quoted text clipped - 25 lines] > Cheers, > James I never thought of that. And, of course, I am not home 24/7. I always thought "why does this happen on the weekends when the vet is closed", but in reality, I suppose she may have had episodes when I am gone. She has woke me up coughing occasionally. I'm very guilty of backing off on the pred because she is not coughing and goes for some time without it. The pred just scares me. She is already peeing so much because she is on lasix and enecard for the heart. The LAST thing she needs is transient diabetes from the pred. Thanks again for responding.
Howard C. Berkowitz - 21 Oct 2005 00:33 GMT Good stuff, James. Perhaps I might add a bit.
> By the way, Flovent *is* a steroid ("glucocorticosteroid") -- the > difference is that it is applied directly to the smallest chambers of [quoted text clipped - 4 lines] > dexamethasone (popular oral/injected steroids). This is why Flovent is > 'safer' systemically. You are quite right that inhaled corticosteroids (I'm using a slightly different term for reasons I'll explain in a moment) tend to have little or no systemic effect. With Flovent, there's an additional safety factor as far as side effects.
There are quite a few corticosteroid drugs. There are two subclasses of effect, glucocorticoid and mineralocorticoid. In general, these drugs are used for their glucocorticoid property, which is the anti-inflammatory action. Mineralocorticosteroid activity, among other things, causes salt and water retention, which often is an undesirable side effect but actually is desirable in some specialized conditions (e.g., adrenal insufficiency; Addison's syndrome).
Prednisone has both kinds of effect, while dexamethasone is pretty much all gluticocorticoid. Besides the type of effect, the choice of drug next involves how much activity it has per milligram or microgram of weight. This isn't too important with an oral drug like prednisone, because you can just give more pills. When the dosage is limited by physical properties, such as the amount that can go into an inhalation, joint injection, or area of skin covered, you want a highly active form, such as the fluticasone in Flovent. These forms tend to be all glutocorticoid.
Incidentally, there are combinations of fluticasone with salmeterol inhalation. Salmeterol is technically a beta-adrenergic stimulant, which is the mode of action of bronchodilators such as albuterol, but not theophylline or ipratropium (Atrovent). Salmeterol's role is preventive -- in humans, it takes 30 minutes or more to take effect, and has absolutely no role in an acute attack. It does, however, contribute to long-term prevention. Albuterol is quite appropriate to give as a "rescue" drug for attacks when on salmeterol.
> The enlarged heart is definitely a complicating factor and will be > important in treatment choices... With an enlarged heart, you want to cut down the work of pumping -- with enough load reduction, the size may come down. Fluid retention adds to the workload of pumping, so the less mineralocorticoid activity, the better for the heart. Thus, oral dexamethasone would be better than prednisone, but inhaled fluticasone, in cardiac terms, is better than both.
> James Perkins, coauthor http://www.fritzthebrave.com Thank you.

I found an interesting Time magazine article that suggests chronic inflammation may cause other problems, including heart. Not that that is here or there, she seems to have BOTH, but interesting none the less.

Fluid retention [quoted text clipped - 6 lines] > inflammation may cause other problems, including heart. Not that that > is here or there, she seems to have BOTH, but interesting none the less. Not just Time magazine, but the general medical literature, often in tantalizing ways. For example, the statin drugs, used to lower cholesterol and related compounds, appear to give additional health benefits. Part of that seems to be an anti-inflammatory effect.
I always chuckle when I see references to "strengthening the immune system", as if that's a good thing. Asthma, for example, is a disease of excessive immune response, where certain immune reactions cause the inflammation. Actually, there are several immune systems that balance one another.
But yes, the research level is moving into clinical medicine. C-reactive protein, for example, is being put into general cardiac health profiles, but also in the differential diagnosis of heart attack.

You know, I am reading "The Good Fat Cookbook" and this goes somewhat with some of the info on coconut oil being a highly beneficial fat in protecting against cardiovascular disease. It also has anti-inflammatory properties.
