Travel Bugs

Been to Vancouver?
   

It used to be that a trip to Florida was a big deal, and a vacation in Europe a once in a lifetime occurrence.  No longer. Now it seems that every week I hear of patients packing up and flying off to climb Kilimanjaro or trek to Machu Picchu. There has been a recent surge in people heading off to Thailand and Vietnam.  All very exciting, but it seems few ever consider their medical condition before they book their exotic voyages.  They're are often disappointed and even mad at me when I suggest that more first-worldly destinations might be preferable.  Not long ago I had to convince a young woman who had just started on cyclophosphamide and high dose prednisone for a Wegener's vasculitis that Laos was not the optimal travel destination for her.  Three days later she called back to say he was going after all because he was feeling much better on the prednisone. 

There are many reasons for her and other rheumatological patients to be cautious in their globetrotting:

First of all, you are much more likely to get sick in a third world country.  30-50% of travelers to these places develop gastroenteritis and the risk is highest amongst the immunosuppressed . Even simple meds like proton pump inhibitors for reflux can increase the risk.  There are also many other nasty bugs out there, all more likely to infect patients on immunosuppressors.

You can't get all the vaccinations necessary if you are taking biologics or other immunosuppressors.  Yellow Fever, for example is a live vaccine and therefore contraindicated.  Fortunately, many countries deny entry without these vaccinces, preventing immunosuppressed patients from even getting in.

Tuberculosis.  As anybody who has taken a biologic knows, TB is a big concern and all patients are screened before treatment is started.  If their PPD test is positive, we treat them before starting.  This cures the infection that was there, but doesn't prevent a new infection from occurring, something that is a lot more likely to happen in a third world country.

If you do get sick, what kind of medical care is available.  I have no idea what the situation is in the vacation regions of Thailand.  It may be fine for all I know, but what I have noticed is that the traveling patients of mine don't know either.  

Even if there is medical care available, who's going to pay.  Some of my patients aren't aware that their insurance has specific clauses concerning prior illnesses.  Here, most insurances won't cover your illness or complications if there has been any modification in therapy in the three months prior to departure.

So now I include travel recommendations with my normal biologic blurb.  Florida sounds nice.  France is lovely.  Been to Vancouver?

Fox-The Lupus of News

Dr. Jon Stewart
 
 Strangely, immunology was put to good comedic use last night, and that's not something I get to say very often. Jon Stewart takes on Fox News, nothing new there.  He suggests that Fox has detected a liberal pathogen at the other news stations, but that their reaction to it is over the top.  They are producing way too many antibodies.  Fox is the Lupus of News

The Stabbing Pain of Gout

Gout hurts.  I've never had the mispleasure of an attack but it apparently feels as bad as it looks.  Literature is rife with descriptions of the pain, but the most convincing I've heard to date came recently from a patient lying in the cardiac unit, foot red and swollen.  "I came in with a heart attack, I was bayoneted in the Korean war, but neither compares to the pain I'm having in that foot!"    

Colchicine Gouging. It Ain't All Bad.

  The FDA in the States continues it's purge of previously grandfathered drugs.  Quinine and Darvon first and now colchicine.  Colchicine had until now kept under the radar, possibly because it has been used, in some form or another , for hundreds or even thousands of years. For all we know, dinosaurs may have munched on the stuff for their gout. The FDA though, obviously not history buffs, would have none of it. But one company was on the ball. URL Pharma, in anticipation of the recall, undertook it's own studies of the drug and was able to acquire exclusive marketing rights for the drug.  Now rebranded as Colcrys, it will cost about $5 per pill, something like 10 times the regular price of the old stuff, and can continue to gouge users for 3 years.  Americans are not amused, with good reason, but there is a good side to this story.  The research done by the company actually produced important, treatment altering, and in the long term, money-saving information. (Cautionary note: I haven't actually seen the study published anywhere, but the results are available via the FDA)

Until now the time tested but obviously not scientifically tested dose of colchicine in acute gout was 1.2 mg, followed hourly until the patient got relief or developed GI side effects.  In a hospital setting this meant that nurses had to check on patients hourly to reassess the situation.  Not infrequently this was impossible and the dosing never actually took place. Even when successful, the prescribed endpoint was when the patient developed  diarrhea.  So often you had a elderly, lame patient in bed with severe diarrhea.  Not a good scene.  Half the time the colchicine wasn't even stopped, the diarrhea being ascribed to C difficile or other causes.  This new study, however puts an end to all that.  They found that 1.2mg followed one hour later by a second dose of .6 was all that was needed.  Nurses around the world are rejoicing.

A second important clarification was dosing in renal failure patients.  In those with a creatinine clearance of less than 30 ml/min, acute gout patients should not have a repeat dose within two weeks.  For dialysis patients, a single dose of .6mg is recommended.  Longer term treatment of renal patients is not discussed but FMF patients with renal failure are given a recommendation of .3 mg/day.

Lastly, it is noted that there is a very strong interaction with clarithromycin as well as lesser problems with other drugs metabolized by the CYP3A4 and P-gp systems.

So there you have it.  Short term pain, at least for Americans, or at least for Americans who don't live near the border, but long term gains for all.  

Chronic Fatigue Patients Not Welcome

Well I guess that they don't read my blog down at the Canadian Blood Services.  Back in February I bemoaned the fact that the exciting news of a viral cause of chronic fatigue syndrome (XMRV virus) and possibly fibromyalgia had been dashed by the inability of other labs to replicate the findings.  It seemed like a long shot anyway, but still it was disappointing.  But now we hear that the Canadian service responsible for blood collecting is the first in the world to put patients with CFS on their not-welcome list, specifically because they are worried about viral transmission of the disease through blood transfusions. Not terribly scientific but I guess it's hard to blame them for being a bit jittery.  Canada was a little slow with HIV/hepatitis C  testing back in the eighties, and many people were infected through blood product use.  In fact, the new Canadian Blood Services arose from the ashes of the previous collectors, the Red Cross, relieved of their duties because of those infections.  I wouldn't be surprised if the French do the same.  People there went to prison for the same reason.  At first I thought that this would mean a big drop in donations, given that so many people have CFS and fibromyalgia, or at least enough to fatigue to think that they may have the disease.  But then again, if you're dead tired all of the time, I don't think you're thinking of giving blood all too often.  And who knows, science seems to be making quick work of this virus theory anyway.  It might not be too long before the gang at the Canadian Blood Services can relax once again.

 

Rheumatologists: The Miley Cyruses of Medicine

Just saw the premiere of what promises to be a pretty bad medical drama, Miami Medical.  It's set in a trauma hospital where the best of the best trauma surgeons work.  We know that because the head nurse tells a newcomer that "trauma surgeons are the rock stars of medicine, and here, we have the Rolling Stones". Yikes!

Pretty traumatic start I'd say, but it did get me to thinking about what kind of musicians rheumatologists would be.  My first thought was Leonard Cohen, slower paced but much more intellectual.  Thoughtful and nuanced.  He also went bankrupt which states fairly well where rheumatologists fall on the pay scale of things.  But then I remembered, I really don't like Leonard Cohen.  

Besides, rheumatology isn't old and slow moving.  In fact, it's one of the youngest specialties around.  In this neighbourhood it only became a stand-alone internal medicine subspecialty in the 70's.  And it's exciting.  I don't think there is a specialty around that's seen the kind of progress we've seen in the last five to ten years.  So no, no Leonard Cohen.  Rheumatologists are the Mylie Cyruses of medicine.  Young, perky and adorable.  And I've got video to back me up.
