Hymenolepis diminuta observations and paper

As described in my previous posts, I have started HDC helminth therapy on June 4th. It has now been over a month. So far I have taken HDC three times – 10 on June 4th, 10 on June 9th, and 20 on June 25th. I have also updated my NA by adding three more on July 6th. It has now been over two weeks since my last HDC dose, helminth therapy wiki suggests dosing every two weeks and adult dosing is in range 30-60 HDC bi-weekly. I am waiting for my next order of 20, the delivery has been slow, and it’s expected to arrive on Friday. After that I plan to increase the dose to 30 as is advised, 20 may be not enough of a therapeutic dose for an adult.

One important observation is that during my period, which happened soon after the third dose of HDC, I did not have to take any pain relievers. I see this as not just a coincidence because last such occurrence happened almost a year ago in July 2018, after I started NA therapy. After that one time unfortunately pain levels during periods went back to usual unbearable and as usual I would take at least two Naproxen gels, sometimes also an ibuprofen. Several times I had to leave work early or work from home. Therefore I was quite surprised that when my period occurred in the end of June the pain began as usual but did not increase to unbearable levels. I went to work as usual, I always keep Naproxen in the drawer in the office and at home, but the pain never rose to the level where I would need a pain killer. I would say that just for this benefit HDC is already worth continuing as not being crippled by pain made me feel more free. Even though it’s not my fault, I often feel guilty leaving home early or asking to work from home every month. I am also not pleased with having to take Naproxen as for me it causes acid reflux and it makes me think that I am undoing the benefits of my efforts to heal the gut.

Another observation was recently increased heat tolerance.  In beginning of July temperatures rose to over 30 degrees Celsius and there is no central AC where I live. In order to cool down the house, I usually have to install two window air conditioner units. These units were taken down for the winter, so there were several days of temperatures around 30 degrees inside. I noticed that my sleep was not as disrupted as it previously would during heat. Also in general I was not as incapacitated by the temperature, I did feel lethargic, but did not have as severe indecisiveness nor mood swings exacerbation that often occur for me during summer heat.

The new lab test results are also encouraging. Free T4 and T3 stayed at the same levels, within normal range. TSH went down to 2.0, which is below the previous value of 2.58. This is a positive result, since some research indicates that the optimal cut- off value of TSH is 2.5 MIU/L. Anti-TPO antibodies have also decreased.

On a side note, I found that someone wrote their undergrad honors thesis on Hymenolepis diminuta. “Impacts of Hymenolepis diminuta (benign helminth worm) colonization on chronic pain and the central nervous system in Sprague Dawley rats“. If I would go back in time, I would prefer to also study neuropsychology. Unfortunately in my undergrad I was calculating bond and option prices. Glad to hear whenever someone is doing research on treatments for autoimmune disorders, specifically the connection between neuropsychiatric problems and inflammation. “The results from this project partially support the tenets of the hygiene hypothesis. Though behavioral results following CCI surgeries were inconclusive, molecular investigation of cytokine levels in the hippocampus showed promotion of an anti-inflammatory cytokine milieu due to the upregulation of IL-10 and downregulation of its receptor. These promising results guide future research toward investigation of cytokine levels in other brain regions, such as the amygdala.
