Early results for Crohn's cure

The Guardian reports that initial results from the first ever controlled stem cell trial (blogged previously in 2007, before the trial started) are very encouraging, with the leader of the trial expressing an expectation that half of the subjects will be cured.

Given the potentially fatal side-effects of the treatment it will only be an option for those most severely afflicted:

The stem cell treatment, which takes two years, is very painful for patients, and involves risks including bleeding, infection and a 1-2% chance of death. The stem cell transplantation is used to kill off the patient's old bone marrow that produces the harmful cells which cause the Crohn's and generate new healthy cells.


In reality it's far too early to consider a cure for Crohn's, especially as we still do not know the cause of the disease. Only long-term follow-ups of the stem cell trial participants will indicate its success as a cure. However, given the dangers in this treatment it is still not an option for the majority of sufferers, and so the research continues.

Infliximab and Azathioprine combo works best

In October last year I noted a report that Infliximab worked better than Azathioprine, and their combination worked better than Azathioprine alone. A new report in Forbes about a larger, lengthier study confirms the earlier report, and finds that the combination of drugs is significantly more effective than either alone.

After 50 weeks, 72.2 percent of patients who'd received the infliximab/azathioprine drug combination were in steroid-free remission, compared to 60.8 percent who'd received infliximab alone and 54.7 percent who had taken azathioprine alone, according to a Digestive Disease Week news release.


Of additional interest is that the subjects of the study commenced their medication regimes earlier in the disease's progression than is usual. The success of this treatment may influence when these drugs are used in future.

Would you like some worms with that?

Bearing in mind that "the plural of anecdote is not data", CBS has a report on a couple of Crohn's patients who attribute their reduced symptoms to self-administered hookworms. As it is not an approved therapy in the US it is quite an adventure to obtain.

Aglietti, who calls himself a gastrointestinal ecologist, takes clients across the border where he gives them a band aid to put on their arm.

On the gauze on the band aid, there is hookworm larvae.

Scots said he experienced some itching where the band aid was, which he understood, was the larvae making their way into the blood stream.

What happens next is the hookworms then travel from the blood stream into the lungs, where once there, causes the patient to naturally cough. Patients then cough the microscopic helminthes up into the throat, then swallow them, and this is how hookworms get to the intestines, where they latch on, and they begin to mature.


There are few ongoing studies into the use of hookworms to treat Crohn's. If it was shown to be successful then scientists would try to isolate the mechanism of its action. This should lead to a safer treatment using controlled medications, rather than live animals. I'm sure that would be much easier to swallow for many people.
