I just got back Wednesday from seeing Dr. Klimas at her new
private clinic (the one not associated with Univ of Miami). Here's a summary of my visit:
The day started off poorly with me sleeping through my alarm and being woken up by the hotel's fire alarm going off. I had to scramble to get my stuff together and missed out on a shower and brushing my teeth (I hope that this is not what Dr. Klimas and company will remember me for).
Thankfully I did make it to the app't on time. Hannah, the office manager, greeted me and I sat and waited. A physician's assistant took me into a private room and we went over my history for about an hour. She asked a lot of questions, very comprehensive. This was mostly about when my "fatiguing illness" started, what the onset was like, my symptoms, how long they had been present, how much they affected my daily activities, etc. After this the PA met with Dr. Klimas for maybe 10 or 15 minutes, then I met one-on-one with Dr. Klimas. This was a real trip after having seen so many of her lectures and videos online. It was like meeting a ME/CFS rock star! She was also much taller than I expected, probably about 5'9 or 5'10 (although wearing heels).
We talked some about the recent XMRV/MLV research (she brought it up, not me, I was trying to give her a break from it as I imagine she's constantly bombarded by patients about it). She talked a little about the recent XMRV conference in Maryland and mentioned that she spent much of it sitting next to Dr. Harvey Alter, the author of the infamous PNAS paper that found MLV's in 86% of the ME/CFS patients. She drew a diagram explaining that the two MLV's they found in the most patients were very similar to XMRV, but not identical. She also mentioned, and this was the first I had heard of this, that the antiretrovirals that were found to be effective against XMRV in vitro were not working (or not working as well, I'm not sure which) against the MLV's that Dr. Alter, et al found.
Next we discussed autonomic nervous system dysfunction and orthostatic intolerance. Before going to the app't I was asked to do a blood pressure and pulse log three times day for seven days. I found that upon waking up in the morning my resting pulse was about 65, but around 100 after being upright for just 5 or 10 minutes with minimal activity. This is called POTS, and was confirmed by the physician assistant on the day of appointment. So I was officially diagnosed with that. Now Dr. Klimas explained something very interesting to me which I had not heard before. That with POTS your body is releasing little bursts of adrenaline to get the heart rate up when standing, and that this is having an stimulating effect on the immune system. So just being upright is revving up the already in-overdrive immune response. No wonder I feel so lousy when standing up! Treating POTS/OI can make a big difference in calming the overactive immune response that is at the heart of ME/CFS symptoms.
So the treatment for POTS/OI to try is Florinef. I had a great response to taking buffered salt tablets some months ago but the effect wore off after about a month. She said this is normal as the salt initially tricks the kidneys but that they eventually compensate. Florinef on the other hand should be able to sustain the effect that I experienced. Since I'm on Florinef she ordered my serum potassium to be checked monthly, the reason for which I've forgotten. She also mentioned that if the Florinef does what it is supposed to, that is to raise my blood volume, I should put on about 2 1/2 lbs. She said that with some patients this is a turn off and they won't try it (that weight conscious?!?). She wanted also to do a tilt table test to see if I had neurally mediated hypotension (NMH), but I had already had six vials of blood drawn and wasn't feeling up for it (nor did I particularly want to pay the additional $300+ it costs). So we skipped it. It's possible that the Florinef will not be enough and will need to add a beta blocker in addition later.
Next we discussed sleep. One thing I had been wondering about was whether it's important to sleep before midnight. I had read from a couple different sources that your body only produces certain hormones in the hours asleep before that time. According to Dr. Klimas it is not important, only that you are consistent and go to sleep at same time each night. I mentioned that Benadryl helps me to sleep so she prescribed a med called doxepin which she described as a more powerful anti-histamine that was also part tricyclic antidepressant(?). She said this helps to get you into SWS (slow wave sleep). I mentioned hearing good things about Xyrem and she agreed it's a very powerful and effective drug but said that you have to be careful about using it when something less potent (and a lot less expensive! -- Xyrem costs $2000+/month) may do the job as well.
Towards the end I asked her about Low Dose Naltrexone (LDN). It didn't seem like she was going to mention it but then when I brought it up she was very enthusiastic, said it was an amazing medication and would prescribe it for me to try. I lamented the lack of clinical trial with LDN despite all the reports of it helping in various immune disorders and she said this actually has an advantage: the price stays low! As soon as the drug companies get involved it will be rebranded/reformulated and the price will shoot up.
She mentioned cognitive therapy being important and having its place in treatment. She discussed Dr. Gupta's amgydala retaining program and said it can be helpful. She used an analogy to describe that some people have laid tracks down in their brains from all the anxiety they've experienced from being sick and that rewiring those 'roads' can change your stress response and therefore affect your body's autonomic/immune reaction to stress.
Before I left she wanted me to have an IV infusion of saline (1 liter). I had never had an IV before so was a bit wary. I sat out in one of the comfy massage chairs in the waiting area and had the IV started. During this time (took about an hour) another patient was sitting across the room and Dr. Klimas came out. She sat down and all three of us started conversing. Dr. Klimas even had time to recommend some local sites to visit since I had the following day free. Interestingly the saline seems to have made a big difference for me. Usually after any sort of travel I come back home and crash for several days but this time I was able to get right back into the swing of things. I may look into getting saline IV on a semi-regular basis.
Overall Dr. Klimas was very positive and encouraging. She mentioned that's she been a HIV physician for 25 years and was there when all the AIDS patients were dying and then saw the corner turn in the mid-90's when the effective HAART drug cocktails came online. She said she feels CFS is close to turning the corner also, and that a lot may change in the next one or two years. Interestingly she said that the XMRV/MLV tests are not ready for primetime but that she is banking the blood of all her patients to be tested when the tests are reliable.
