During the past couple of months several people have asked me for the contact details for Prof. Dr. Kenny De Meirleir and his Himmunitas Foundation as they do not have a website yet. The information may be incomplete because I had to rely on my own limited experience and information found on forums.
Himmunitas Foundation
The Himmunitas Foundation is a privately run clinic for the biomedical treatment of ME/CFS and is set up as a non-profit organization. The Himmunitas Foundation is housed in a nondescript building in Neder-Over-Heembeek near Brussels (Belgium), which it shares with 2 other companies.
Who’s Who at Himmunitas
- Prof. Dr. Kenny De Meirleir, MD, PhD: World-renowned ME/CFS clinical/research leader at the Free University of Brussels in Belgium, co-editor of the Journal of Chronic Fatigue Syndrome, co-developer of the Canadian Consensus Document for ME/CFS, and author of more than 600 articles. An article by Cort Johnson can be found on ME/CVS.net: Dr. Kenny De Meirleir – Man on the Move for ME/CFS (Dutch website, scroll down for the original English article)
- Christine Tobback, dietitian specialised in food intolerances and pseudo-allergies. Website: Optinutrics
- Dr. Kris Vollon, orthomolecular doctor.
Tests
The tests are done at the clinic after which the samples are send to labs in Belgium, Germany, USA, … The number and the type of tests will be determined during your first consult with Prof. Dr. De Meirleir. I had to go to the clinic four times over a period of a month to get all the tests done, but for foreign patients they do all the tests in two consecutive days.
There is a hotel nearby that they recommend, the EuroVolleyCenter. I have stayed there myself on two occasions when I had to be at the clinic at 8 am — Brussels has the worse traffic jams in Belgium — and it is conveniently close to the clinic. They even provide transport to the clinic.

Disclaimer
A lot of people found and are still finding the information I provide here, the contact information for the Himmunitas clinic of prof. dr. De Meirleir, useful. I had to look it up myself to make an appointment and go there, so I might as well share it. However, this is not a recommendation to go to the Himmunitas clinic. I have been a patient of De Meirleir for 7 months (of treatment, if you start counting from the first visit then it is 1 year). I got worse, a lot worse. It was only after quitting that I became a bit better again. So, I cannot recommend the treatment. My 2 cents are to think it through because it is very expensive and to consider the following 2 observations (to the best of my knowledge):
- He will order a lot of tests and not all of them will be medically significant; meaning other doctors, even those unprejudiced towards ME/CFS, will not consider them useful or of any value.
- There is no biomedical (evidence-based or science-based) treatment for ME/CFS. Yes, he is a medical doctor and a professor, but the treatment is to be considered alternative (unproven at best) or even experimental.
Take care.

Thank you very much for all these informations!
Thank you so much
Did the treatment work for you?
How are you doing now?
Was it expensive?
@Krista,
No the treatment didn’t work, it made me much worse. After 7 months of treatment and a lot of money I quit. It took the best part of this year to recover from treatment.
@Johan
I am so sorry to hear that. I read good and bad comments of the treatment. I want to make an appoitment but I still hesitate…..
@Krista,
I understand, it is a lot of money and doing nothing feels too much like giving up, at least to me. If I wouldn’t have done it, I would probably be still considering making an appointment as well – as in not to leave a stone unturned. Looking back I don’t regret the tests (in general, some were useless), but I should have followed my instinct and quit after the 3rd month of treatment as things didn’t add up. It is not an easy decision to make and I live in Belgium, it was an hour and half drive.
Hi Johan……thanks for sharing and informing us about your experience with it,i would like to know if your treatment was with gcmaf..??…
there is Spanish guy who is taking it after Meirleir appointment and he says he’s improving a lot……¿¿?
thank you……
@Amaia,
No, I wasn’t treated with GcMAF. I sometimes hear from ME/CFS patients who know patients (indirectly) who improved on GcMAF, but the 5-6 patients I know (directly) who got treated with it experienced no improvement. I recently saw a message on Facebook that GcMAF is not without side-effects. There are 2 things to consider here:
I have been consulting Dr. De Meirleir for a little less than a year now, and have -like others before me- come to the conclusion that it isn’t worth the effort, and certainly not the money. The tests are exorbitantly expensive, not refunded by national health insurance, and, as Johan said, not always relevant. The test reports seem to mean something to DM himself, though he always tells me he has to ‘interpret’ them, but not to other doctors. He constantly contradicts himself, saying one thing during the consultation, and recommending something else in his written recommendation to my GP. He knows his own ‘stuff’ about immunity, but completely ignores all other health aspects or issues. His recommendation for thyroid hormone, for example, would have killed me. Luckily, I was on the case and consulted my endocrinologist. There is no room for dialogue, true consultation or asking questions, not even a proper anamnesis. Symptoms have to be indicated by ticking boxes on a preprinted form, which he then silently reads in the presence of the patient, rather than -God forbid- asking the patient directly. His manner is aloof, sometimes even rude, and does not inspire confidence. I suspect him of seeing his patients, not as human beings, but as potential creatures for experiments and a source of income. During my last consultation, he roundly asked me ‘so what do you want from me?’, because I had the temerity of not getting better from his treatment. He then prescribed another series of tests amounting to 730 Euros (including a 280 Euro stool analysis, which my GP can have done at a fraction of the cost). When I explained I didn’t have that kind of money, I was told simply that ‘the Professor could not help me any more’.
Fine by me, I don’t want to be ‘helped’ in this way. The only good thing about seeing DM is that when I have to see the national health doctor to prove disablement and incapacity to work, I can honestly say I have tried everything possible to get better.
@Esther,
I like this quote:
It almost sounds like a rite of passage, but you are right. After quitting his treatment I no longer asked myself the questions “What if this doctor has a treatment?”, “Maybe I should make an appointment with that doctor?”, “Should I see that therapist?”, “Should I try this treatment?” …. I had CBT, I tried out dozens of CAM treatments and now I have done the so-called biomedical approach which in reality isn’t biomedical but experimental.
I’m trying to remember – doesn’t Dr. DeMeirleir own or part-own a commercial lab? Are the tests he orders done by this lab?
@Michelle,
Yes, details are a bit hazy, but he (co)founded RedLabs that does a lot of his tests, he also (co)founded the lab for the neurotoxic metabolite urine test and I have seen his name mentioned with VIP Dx as well.
Hi Johan! I am sorry for your experience. Sometimes we find what we need, through what “we do not need”. I have been through many treatments, before finding tools that work for me. My son, has the same illness, yet needs different treatments. I am interested, if anyone on this board is open to discussing;what tests are being done at this clinic? Specifically what blood tests and what treatment methods are being offered? Thank You. Julia
@Julia,
I haven’t mentioned all the tests I have done in detail, but to give you an idea I will refer you to this article: First Visit to Himmunitas and Prof. Dr. De Meirleir
I can see the potential link with Biochemsitry. I bet this will be huge with these diseases in the future.
It looks as if NO infectious pathogens are being tested for. Shame. We know the underlying factor is infectious pathogens.
I am glad it helps for some people.
@Julia,
He does test for some pathogens: EBV, HHV-6, …
