Post Accutane Dysautonomia?

2032 views

I am a healthy 19 year old athlete, or at least I thought I was, until I began having these weird episodes where I will begin sweating, but have the chills too. My heart races and I feel spacey and out of it. It feels as though the blood is just rushing from my head to body. The episodes can last from a few minutes to a few hours and seem to come out of nowhere. The doctors that I have seen cannot find anything wrong with me, but I know this is not normal. I have also had some weird lab results, shown below.

Childhood History

I have no major medical history except for a year of amoxicillin for ear infections and Miralax for constipation as a toddler. Around the age of about 11, I developed facial tics that were resolved with diet change (gluten free) and magnesium.

I have played soccer since the age of 5 years old. I would continuously head the ball, to the point where the parents would jokingly take bets on how many times I would head the ball. Around my sophomore year in high school, I had some back pain and a chiropractor said I have mild scoliosis with a Scheuermann’s presentation. This is basically a benign flattening of the vertebra. He said exercise was important. I changed my mattress, exercised regularly, and the back pain went away. The only other thing that I deal with regularly is altered sleep. I can fall asleep OK but I wake up several times during the night and have trouble falling back asleep.

Acne, Antibiotics, and Accutane and First Episodes

During my senior year in high school I developed severe cystic acne. I tried some dietary interventions, but nothing seemed to help. I did six weeks of doxycycline, which did nothing. I then went on my first round of Accutane for about six months in the spring of 2022. The following fall of 2022, the acne returned. I went back on Accutane for another five months. I discontinued the second round of Accutane at the end of May 2023. Then, one month later, at the end of June, I had my first episode of sweating, chills, heart racing, and feeling of spaciness. It seemed to come out of nowhere. We thought it was viral. A few friends developed Epstein Barr in May and so I thought maybe I had it too, as I was in close contact with them. About a month later, I had another episode and then about two more this past summer. They seemed to be lessening in intensity and duration.

This last fall, we had bloodwork done (Figure 1.). My labs showed that I have exposure to EBV, Lyme and a couple other viruses, which according to the doctor, were not extremely elevated. My albumin, the liver enzyme AST and my progesterone were also high, while my RDW (red cell width) was low at 11.7 (12.2-15.3). My vitamin D was barely above the reference range at 33.3ng/mL (32-100), and strangely my thiamine was super high at 25.0 ng/mL (2.7-10.1) even though I do not supplement. Finally, there was evidence of a lingering respiratory infection Chlamydophila pneumoniae.

While these numbers were not a concern to the physician, these episodes I have are not normal and so something is going on.

College and More Episodes

Despite all of this, I entered college away from home and felt ok for two months. Then the night before Halloween, out of nowhere, I had another episode. This time it lasted almost two hours. I was sweating, had chills, and my heart was racing. When I feel it coming on, I have to lay down. It feels like the blood is just rushing from my head and body. This time my hands also sort of cramped/seized up, which was scary. I was not doing anything out of the ordinary. I was preparing to go on a road trip. The following night I had another smaller episode. This one didn’t last more than 10 minutes.

Why Is This Happening?

No one seems to know why this is happening. Are the abnormal labs really of no concern? How about the elevated thiamine despite not supplementing? Is there something going on there? Could I possibly have an altered thiamine transporter system or some other genetic defect that makes it difficult for me to use thiamine? Could my symptoms be spinal related? Is my autonomic nervous system altered after coming off two rounds of Accutane? This is very scary to me as a 19 year old. I would like to learn everything I can from you and all the people here sharing their stories. I do not want to get worse.

Thiamine Deficiency: A Slow Road to Dementia

‘Jo, you’ll be relieved to hear the tests are all normal.’

I’d heard this line so many times, and it wasn’t reassuring. Each time it became less likely that I had an illness that could be defined, diagnosed, and consequently cured, or even treated. If there was nothing wrong with me, why did I feel so awful? I had been gradually deteriorating over months, perhaps longer.

Fatigue and Other Seemingly Innocuous Symptoms

It’s difficult to say when I first felt unwell. One of the initial symptoms was terrific fatigue – struggling to find the energy to carry on each day at work. I was taking longer and more frequent tea breaks and relying on sugar to give me the buzz to carry on. Of course, it didn’t help that I didn’t sleep well. I would fall into a deep sleep early evening and then wake feeling strangely on edge with a racing heart, unable to sleep for most of the night. Even if I could sleep, it didn’t make me feel any better.

There were several other symptoms, which I could explain away, but one odd symptom was muscle twitches or fasciculations. These were worse when I was tired or had been more active. I also had dodgy guts – more about this later.

Even though I was exhausted I could continue working, being a mother to our four children – albeit a rather terrible one that repeatedly fell asleep in the middle of bedtime stories, until I developed brain fog. I felt like my thinking was occurring at less than half the usual speed. I struggled to hold a conversation, as this required listening, interpreting the other person’s words, formulating an answer, and talking. I would have to really concentrate to think about anything. I would forget things unless I wrote them down, which just meant I had unfinished lists scattered everywhere.

After falling on the ward where I had been working as a doctor, I finally acknowledged that I was sick, even if there was nothing apparently wrong with me. Once I stopped working, I deteriorated further, such that I was unable to recognize people and even places.

A Slow Road to Dementia

This was over 10 years ago. Clearly, I’ve improved since then. I’ve written a book to try to characterize my symptoms, explain what caused them, and why it was difficult to make a diagnosis. This seems even more pertinent since a lot of the symptoms I suffered with then resemble long Covid now.

My main concern was that I had developed dementia. I had many of the features: I struggled to remember recent events, I had problems following conversations, I was forgetting the names of friends and even commonly used objects, and I was repeating myself and having problems with thinking and reasoning. I also had difficulty recognizing where I was — this is visuospatial disorientation — a key marker of dementia.

Since the medical profession seemed to have no idea how to treat me I decided to try to work it out for myself. What choice did I have? Away from work, I had time to slowly read through medical papers, whilst I rested. I recognized that my symptoms improved after taking antibiotics for a gum infection. Any exertion made me markedly worse, but not immediately afterward, it would be the following day and last for several days. I improved if I rested. My other symptoms included pains in my hands and feet. I thought this was arthritis initially, but when I developed pins and needles and subsequently numbness, I realized this was a peripheral neuropathy – a problem with the sensory nerves in my extremities.

Some months earlier a close colleague had told me I was thiamine deficient, mainly because I had lost a lot of weight. I was taken aback, assuming he thought my diet was poor, or that I was drinking alcohol. I hadn’t drunk any alcohol for years as it made me feel rough after a few sips. I investigated thiamine deficiency and found that it causes loss of sensation as well as loss of balance; I already knew it affected memory from treating alcoholics under my care.

My friend kindly agreed to try high-dose intravenous thiamine on the ward. Neither of us really thought it would work, but it was worth a shot. I was astounded when after a few minutes of the infusion I started to be able to think clearer and even the pains in my hands and feet disappeared. I practically skipped off the ward to buy oral thiamine and dose up. Sadly, thiamine tablets didn’t work and two days later I was back on the unit begging for more shots. This thrice-weekly dosing of thiamine infusions continued for months.

The Gut Connection

I trained in Gastroenterology and General Medicine. They say doctors make the worst patients. For as long as I could remember I had suffered from intermittent severe central abdominal pains, which usually occurred after eating quickly on an empty stomach. According to my mother, I had been a colicky baby and had also returned to the hospital as a new baby with uncontrollable vomiting. Nothing abnormal was found.

In fact, not all the tests I had were normal. After several second opinions, I had a few abnormal tests. I had a CT scan of my abdomen, which showed that I had gut malrotation. The severe pains I had experienced throughout life were due to small bowel volvulus – twisting. I learned that if I stopped eating and lay down on my back the pain would gradually subside. Each time my guts twisted scar tissue formed adhesions, slowing down my gut movements.

My guts had been noticeably abnormal for many years. I had noisy guts and passed very loose, frequent motions. I don’t know many slim 20-year-olds who suffered from severe gastro-esophageal reflux as I did. As this progressed, I developed recurrent chest infections and required multiple courses of antibiotics. Eventually, I worked out that I was aspirating gut contents into my lungs each night, and I stopped eating in the evening and propped myself up with many pillows. All sorted – no more chest infections – no more antibiotics.

One of the other abnormal tests was an incredibly low vitamin D. Through late-night searches of anything vaguely relevant and my gastroenterology knowledge I worked out that a low vitamin D occurred in bacterial overgrowth. This made sense. I had developed bacterial overgrowth in my small intestines — the part of the gut responsible for the absorption of nutrients from food.

Small intestinal bacterial overgrowth or SIBO is due to an excess of bacteria in the small intestines. There are many risk factors including sluggish guts from adhesions, previous surgery, medications that slow the gut, but also multiple courses of antibiotics, poor immune system, and use of drugs that block acid production in the stomach, as well as pancreatitis. I’m sure that a diet high in sugar didn’t help.

I had another test specifically looking for bacterial overgrowth, which the nurse (a colleague I’d worked with many times) and I interpreted as abnormal. The consultant I saw thought the machine must have broken. This was frustrating; after so many normal tests to have a wildly abnormal test attributed to faulty equipment. I decided it was better to treat the patient (me) rather than a dubious test result. After starting antibiotics, I no longer needed the thiamine infusions. The diarrhea also improved.

I worked out that I had bacterial overgrowth from mal-rotated guts, obstructed from adhesions, which improved with antibiotics and were eventually treated with corrective surgery. I also had severe vitamin D deficiency, which was corrected with injections, and thiamine deficiency, which I subsequently managed with a fat-soluble thiamine analogue — benfotiamine. I found a paper online reporting thiamine deficiency in extremely obese patients who had undergone surgery on their small intestines to aid weight loss. Many of these patients had thiamine deficiency; they also had high folate, which was thought to be a marker of bacterial overgrowth. Oral thiamine had no effect on their thiamine levels, but after taking antibiotics the patients’ thiamine returned to normal. Interestingly, my folate was high.

What was less well known was that some bacteria produce an enzyme called thiaminase, which destroys thiamine. I can only assume that I had these kinds of bacteria in my gut. Interestingly these bacterial enzymes do not destroy benfotiamine.

I followed up on my theory of the underlying cause of dementia: that too many bacteria, producing a lot of thiaminase enzyme, destroy the thiamine in our food rendering us thiamine deficient. I found out that thiamine is essential for all living things, and it is necessary for the release of energy from food, particularly sugar or glucose. The brain only uses glucose as an energy supply. There are reports of low thiamine levels in the brain in patients who have died of dementia. Glucose metabolism in the brain is never normal in dementia. Benfotiamine has been shown to improve mild cognitive impairment. I speculated that this was the cause of my brain fog.

Thiamine Deficiency: The Missed Diagnosis

Why was it so difficult to make a diagnosis? I believe there are several reasons. Firstly, thiamine levels are rarely tested in the UK. Even though I had worked in the NHS for over 20 years I had never requested a thiamine test. Secondly, thiamine deficiency is known to present in widely differing ways. This is like many of the mysterious syndromes — a constellation of recognizable symptoms and signs with largely normal tests: irritable bowel syndrome, fibromyalgia, etc., and also long Covid. Thirdly, I wasn’t listened to. I’m not sure whether this is because I’m female, but I became extremely sick before anyone really tried to help, and even then I was reliant on friends I have in the medical profession.

I’m remarkably well now. I regained my memory and ability to think, although it probably took a couple of years. My guts still aren’t completely normal, but bacterial overgrowth is often a chronic condition. I still take supplements and I’m careful with my diet, avoiding sugar and alcohol. My diet is quite restrictive, but it’s worth it. I wouldn’t want to go back to how I was.

Vitamin D Plays an Integral Role in Adaptive Immunity

6367 views

Severe Adverse Reactions Include Vitamin D Deficiency and Autoimmunity

Hormones Matter researchers discovered that, inter alia, severe adverse reactions to any of the surveyed drugs trigger significant but varying autoimmune responses. Moreover, the research revealed an underlying consistency involving all reviewed drugs: vitamin D deficiency.

Vitamin D Helps Regulate the Adaptive Immune System

The adaptive immune system comprises the body’s intricate network of antibodies and special types of white blood cells (called sensitized lymphocytes ) to thwart new and previous invaders including viruses, bacteria, and drugs. When the adaptive immune system is not strong enough to endure external disruptions such as severe side effects of drugs, it can go awry by signaling antibodies and sensitized lymphocytes to attack healthy cells. This response is called autoimmunity—when the adaptive immune system’s cells do not recognize previous invaders and designate healthy cells as those invaders. In other words, the body’s immune cells attack its own healthy cells.

Scientific research over the past three decades solidifies the connection between vitamin D and autoimmunity. Vitamin D plays an integral role in the regulation of the adaptive immune system. Adequate vitamin D in our bodies can protect us from autoimmunity because adaptive immune cells contain vitamin D receptors (VDRs). These receptors are attached to the surface of the adaptive immune system’s antibodies and sensitized lymphocytes. The VDRs act as “gate keepers” by signaling what external substances, e.g., components of medications, can enter a cell. The VDRs must be replete with vitamin D to effectively regulate adaptive immunity. When the VDRs receive adequate amounts of vitamin D, they enable the adaptive immune system to function properly by attacking new and previous invaders.

When the VDRs attached to the adaptive immune system’s cells do not contain sufficient vitamin D to attack invaders, autoimmunity may kick in, causing the death of healthy immune cells. Thus, low vitamin D levels can lead to autoimmune diseases including thyroid disorders such as Hashimoto’s and demyelinating diseases including multiple sclerosis (MS).

Vitamin D and Hashimoto’s Autoimmune Thyroid Disease

The Real Women, Real Data research also uncovered another consistency among severe adverse reactions to the reviewed drugs: Hashimoto’s thyroiditis, an autoimmune disease caused by abnormal cells constantly assaulting the thyroid gland
.
Vitamin D receptors are present in the thyroid as well as the pituitary, the pea-shaped gland that controls the thyroid. Not surprisingly, low levels of serum vitamin D have been linked to Hashimoto’s thyroiditis, according to recent Turkish medical research:

Published in a 2013 issue of the journal Endocrine Practice, a study conducted at a training and research hospital in Ankara demonstrated that serum vitamin D levels of female chronic Hashimoto’s patients were significantly lower than healthy subjects. Furthermore, the researchers discovered a direct correlation between serum vitamin D levels and thyroid volume as well as an inverse correlation to the antibodies involved in the thyroid.

Researchers at Medeniyet University’s Goztepe Education and Research Hospital in Istanbul learned that 92 per cent of their 161 Hashimoto’s thyroiditis cases had serum vitamin D levels lower than 30 ng/mL (12 nmol/L), a value characterized as “insufficient.” Published in a 2011 issue of the journal Thyroid, the study reports an association between vitamin D insufficiency and Hashimoto’s thyroiditis.

Vitamin D and Demyelinating Disorders

Another disturbing outcome of the Real Woman, Real Data research is the reporting of neurological and neuromuscular symptoms, many which of are consistent with demyelinating disorders such as MS, an autoimmune disease. The development of MS occurs when a poorly functioning, adaptive immune system gradually attacks the protective covering of the nerve cells (called the myelin sheath) of the brain and spinal cord. This potentially debilitating process is called demyelination.

Scientific—primarily epidemiological—research indicates an association between vitamin D levels and the risk of developing a demyelinating disorder such as MS. VDRs exist on nerve cells and the myelin sheath. When the VDRs receive adequate amounts of vitamin D, they help protect the integrity of the myelin sheath. However, when the VDRs do not contain sufficient vitamin D, autoimmunity may occur, resulting in the death of healthy nerve cells. Numerous clinical trials are underway to assess the connection between vitamin D status and the likelihood of developing demyelinating disorders.

Low Vitamin D: The Chicken or the Egg?

The connection between low vitamin D status and the development of autoimmune disease is genuine. However, medical research has not yet determined if vitamin D deficiency plays a role in the development of autoimmune disease, if low vitamin D levels are a consequence of the disease itself, or if vitamin D deficiency acts as both a cause and effect. The authors of the aforementioned 2013 Hashimoto’s study concluded,

“Finally, our results suggested that there may be a causal relation between vitamin D deficiency and development of Hashimoto’s thyroiditis. On the other hand, there might be a possible relation between severity of vitamin D deficiency and progression of thyroid damage. However, further studies are needed especially about the effects of vitamin D supplementation on prevention and/or progression of autoimmune thyroid disease.”

Proactive Protection against Severe Adverse Reactions

We could wait years (or decades) to garner the results of further scientific studies and clinical trials to define the exact relationship between vitamin status and severe adverse reactions to vaccines and medications that culminate in autoimmune disorders. Or we could be proactive by taking daily vitamin supplements and enjoying moderate sunlight exposure to increase our vitamin D levels.

It is imperative to take enough vitamin D3 so this essential nutrient will be stored in your cells to help regulate your immune system. The greater your serum vitamin D level (easily obtained from a simple blood test called 25(OH) D, the more likely you will benefit from a stronger immune system that protects your body’s cells from attacking one another.

No one wants to endure severe adverse reactions to drugs such as Gardasil and Lupron, let alone an autoimmune disease. Attaining and maintaining adequate supplementation provides a safe, easy, and inexpensive approach to improved preventive health. By empowering yourself with adequate vitamin D, you may reap the benefits of avoiding disease and enjoying better quality of life.
