Tuberculosis May Become A Global Threat Again

Iphtashu Fitz writes "The journal Nature Medicine is due to release a report today on how highly drug-resistant strains of tuberculosis are on the verge of becoming a global epidimic. Strains of TB that are highly resistant to antibiotics are becoming increasingly prevalent in places like Russia, eastern Europe, and China, and only small changes are required to make these strains start spreading quickly. Treatment for multiple-drug-resistant strains of TB requires a carefully monitored cocktail of drugs taken for months on end, a regimin that many, especially in poorer countries are unlikely to follow to completion. The strategy used by the World Health Organization to combat TB, the "directly observed treatment, short course" or DOTS, involves using trained health workers to watch patients take their long courses of drugs, since even a little carelessness could result in TB mutating into a more drug resistant form within the patient." Oh, Alexander Fleming ? where art thou now?

    All my life I've tested negative. A few years after moving to California, the great gateway to the developing nations of Asia, things changed. Where I worked they provided free TB tests, I thought "Cool, I'll save on going to my doctor and have my folder updated for the next few years", so I took the test. A pink spot appears on my left arm, while in the midst of a critical project I'm managing and -pfft- I'm sent home until I can prove I don't have the disease. After a week of cooling my heels at home, having a chest x-ray and hand-written letter from my doctor I return to work. His assessment is I don't have tuberculosis (formerly called Consumption in the olden days), but I've been exposed to it so my immune system is on red alert. I can no long have the little poke under the skin, but from now on must do the full doctor visit thing, whatever that will entail, including deductables and co-pays. Yay.

    So someone probably coughed in an elevator, in a kitchen or whatever and myself and anyone else in the vicinity were exposed.

    I was put on Isoniazid with vitamin B6 (because Isoniazid knocks the sh!t out of your liver) for 9 grueling months. The first month I felt like I was dying. It really played havoc with mountain biking and meant no beer for 9 months, it was glorius to be off it.

    Even two years ago it was recognized that there was an epidemic of TB in the asian sub continent and many of the H1B workers to came in may not have had it full blown, but had it and were bringing it into the USA. Could very well have been one of the fine people I worked with shortly after moving to California, but by no means would the state be unique. On weekends and holidays I'm a cyclist and put in long miles with considerable effort, which means I'm pretty well in tune with how my lungs are doing. Any little change, a day more phlegmy the others makes me take notice and track whatever seems be be going on. For that I thank all the brilliant people and lobbyists who made it so much easier during the tech boom to let people into the country on a rush to fill positions in businesses (which lobbied like hell for increases in H1B and more lax health screening.)

    A little background on TB, the bug is not killed by the immune system, but isolated. If it's under control that means a little cyst-like structure is built around it which hopefully contains it the rest of the hosts life. A severe respiratory infection can weakend the immune system to the point that the bug gets out and wreaks havoc, more likely at advanced age.

      Wait a second, you didn't have TB but were put on a liver-destroying and probably resistance-breeding drug?

      As the medical establisment goes in the USA, if there's a chance you have TB, they treat you as if you did have it. This was effectively: take the treatment and you can go back to work, don't take it and take your chances unemployed. See the light?

      Also, I would assume a bug in cyst-like structure eventually dies. Can it really survive forever without food in a warm human body?

      Various organisms are capable of surviving extended periods without activity, food, warmth, etc. Some bacteria, so I've heard, can survive hundreds of years waiting for conditions to be right to shed some little shell they get by in.

      Yes, developing countries do have TB. And I am sorry to know that you contacted. However, your direct attack on H1B workers for this is just bizzare and xenophobic. How about the 8 million Mexican illegal immigrants giving you a little TB infection? Why do only H1's figure in your post? BTW, TB is a "white-man's disease" we in India were introduced to TB due some assholes coming over from the "developed" world in the 16th century.

    when we let big pharmaceutical companies take control of R&D.

    Most antibiotics today are BASED on peniciline. Truth is, these resistant TB strains are resistant against PENICILINE-based antibiotics.

    As I saw on Discovery once... There are thousands of natural antibiotics which are extremely complex. Some can be taken from cactae in South America, some can be taken from certain species of ants.

    But natural antibiotics just can't be patented (think of it as the OSS medicine), and companies don't give a sh*t about them.

      Ever heard of Tamoxifen for treatment of breast cancer? That drug was isolated from the Pacific Yew tree. Drug companies have a HUGE interest in "natural" drugs, but that does not mean they will find the cure for all diseases. It takes years to isolate and test the chemicals then more years to figure out how to make the drugs they did find in the tests. Then they have to scale the process to make tons of the drugs. Even with "fast-tracking", Parallel computing, folding algrithms,etc. you can expect 5-7 yrs from R&D to drugs you can buy.

      I know that the pharmaceutical companies are "THE MAN", and therefore evil, but let's think about what that means for a little bit. You are saying that there exists a better, non-patentable method of producing a drug. And it is not being used because the pharmaceutical companies cannot patent it and thereby ensure profitability. No one else is making drugs from those sources either - even though it is known to be non-patented. So this is virtual proof that if we weaken the patent system, we will have LESS drugs available, not more. In fact, pure logic dictates that we should allow someone to patent the unpatentable natural antibiotics - at least then they would be available!

      Like you, I don't really like the way this works. But my question is what can replace the "market force" of patent law to make pharmaceutical companies make these (and other similar) drugs? This is actually a pretty common dilemma. As a society we really need to figure out a way to make people rich for doing things that are obvious, but necessary - otherwise noone smart and experienced enough to build a company will bother.

      This is one (of many, in my opinion) of the problems with patents as they are today. Anybody have any ideas?

    Bacteria (not computer, although I suppose it could apply too) evolve regularly. Some strains of staph are now resistant to most antibiotics. I had a case of MRSA (Mesocillin Resistant Staph Aureus) two summers ago after having surgery. It was most unpleasant and only an IV-induced superdrug called Vancomycin could destroy it. So, to me it's not all that surprising that TB is making a comeback. It finally figured out how to immunize itself.

    History will show that the baby boom and X generations, who worry and fret about every little imagined risk, actually will have lived in the golden age of human health. This will be the period when antibiotics were effective and vaccines developed in the mid 20th century kept them safe from the viral diseases. Evolution will overcome all those safeguards.

    The solution is to come up with drugs and distribution methods that don't rely on patients' ability to follow difficult regimes. Eg, why not implant all the doses at once with some sort of metering device that insures that the course is followed? Otherwise, you eventually will have to enforce treatment by withholding treatment from those who can't follow the schedule.

    More Importantly, it is coming, just not how you beleive.

    While the Black Death did indeed kill less numbers, it did kill 25 million people(over 5 years), where the 1918 flu killed upwards of 40 million in about a year.

    The thing is the Black Death killed 1/3 of europe's population, fueling the greatest economic boom this planet has ever known (at least the one that didn't fall like the internet bubble).

    Upcomming in the next quarter century is the death of the Baby Boomers. When they start to pass on, they will leave behind more money and jobs than you can possibly imagine. This will fuel a new era of real money the likes of which the modern world has never experienced. Unfortunatly, the government that is in power when this begins to happen is going to get credited with the economic boom that will happen, without actually doing anything.

    Now, while the boomers don't represent 1/3 of the population, they nearly represent 1/3 of the weath, possibly causing the same sort of wealth redistribution that occured at the end of the Black Plauge. Trouble is, that the goods that North Americans will buy, will often be manufactured offshore, thereby moving the money off to other countries. Trouble with that? The governments of the last 40 years have been sucking the North American people dry, and the money that should rightly end up in the pockets of local producers, will move to their offshore competitors.

    So, When you get your inheritance, Buy North American! ... wow, neat rant ...

    I highly recomend reading Mountains Beyound Mountains: Health the World: The Quest of Dr. Paul Farmer

    He essentailly discovered that DOTS doesn't work

    In this excellent work, Pulitzer Prize-winner Kidder (The Soul of a New Machine) immerses himself in and beautifully explores the rich drama that exists in the life of Dr. Paul Farmer. A Massachusetts native who has been working in Haiti since 1982, Farmer founded Zanmi Lasante (Creole for Partners in Health), a nongovernmental organization that is the only health-care provider for hundreds of thousands of peasant farmers in the Plateau Central. He did this while juggling work in Haiti and study at the Harvard Medical School. (Farmer received his M.D. and a Ph.D. in anthropology simultaneously in 1990.) During his work in Haiti, Farmer pioneered a community-based treatment method for patients with tuberculosis that, Kidder explains, has had better clinical outcomes than those in U.S. inner cities. For this work, Farmer was recognized in 1993 with a MacArthur Foundation "genius grant," all of which he donated to Zanmi Lasante. Using interviews with family members and various friends and associates, Kidder provides a sympathetic account of Farmer's early life, from his idiosyncratic family to his early days in Haiti. Kidder also recounts his time with Farmer as he travels to Moscow; Lima, Peru; Boston; and other cities where Farmer relentlessly seeks funding and educates people about the hard conditions in Haiti. Throughout, Kidder captures the almost saintly effect Farmer has on those whom he treats. Copyright 2003 Reed Business Information, Inc.
