Elevated parathyroid hormone (PTH) and 1-25-D, calcium deficiency and calciphylaxis

I’m feeling so much better after only two days of calcium supplements that I feel like throwing a party. Fatigue is tiring. Replenishing supplies of a trace nutrient deficiency can help resolve symptoms so quickly that it feels like a miracle. I’ve experienced rapid resolution of symptoms in the past when I had a problem with low B1 intake [2] that was due to a low intake of everything – I had an anorexic appetite at the time which I later found may have been due to an underlying zinc deficiency.

The anorexic appetite symptom resolved when I added zinc and B6 supplements after reading about pyroluria. Pyroluria is not yet treated or accepted by most main stream health practitioners but it is believed to be due to a genetic defect affecting an enzyme that helps break down old hemoglobin for reuse and recycling. Molecules of B6 and zinc are involved in the process and in normal health would be recycled but if the person has the genetic modification than the B6 and zinc is released in urine rather than being retained for reuse. [1]

Calciphylaxis is a symptom that is not well understood but is associated with severe hyperparathyroidism. It is a rare symptom in the general population but is seen more frequently in people with end stage renal disease. When the kidneys are no longer able to make normal amounts of 1, 25 dihydroxy D the plasma calcium levels can drop. And to try to maintain normal calcium levels the body responds by having the parathyroid glands increase production of parathyroid hormone which in normal health would tell the kidneys to activate more 1, 25 dihydroxy D which would then tell the intestines to absorb more calcium and would tell the bones to release more calcium from storage. [3] But in end stage renal disease there aren’t functional kidneys and the elevated levels of parathyroid hormone can cause other symptoms like irregular or rapid heart rate or in severe cases calciphylaxis may occur.

Calciphylaxis “is a poorly understood and highly morbid syndrome of vascular calcification and skin necrosis.” [4] The word calciphylaxis may refer to the syndrome or to the patches of necrotic (decaying) tissue which may occur internally on the surface of bones or externally in patches on the surface of the skin. The decaying areas occur more commonly on the lower legs. The areas can first appear as reddish or purplish bruised areas that may feel like they have small hardened nodules under the skin. The skin surface may be itchy and eventually may break down to be an open wound that doesn’t heal easily. There is a risk of skin infections developing in the open wound which can become severe enough to cause sepsis and death as the patches of decaying skin or bone areas do not heal well.

Calciphylaxis is more of a risk with end stage renal disease but it has also been found in people who had normal vitamin D levels and normal kidney health. And “high dose vitamin D administration is capable of inducing STC (soft tissue calcification) and calciphylaxis in murine models. [56, 57] In an attempt to reestablish normal calcium-phosphate homeostasis, ESRD patients receive vitamin D analogs that could theoretically increase their risk of calciphylaxis if hyperphosphatemia and hypercalcemia ensued. [58, 59]” [3]

“Experimental sensitizing events and agents included nephrectomy and exposure to parathyroid hormone (PTH) and vitamin D. Substances used as challengers included egg albumin and metallic salts. Calciphylaxis was the end result.4  – from a 1962 study, abstract is free. [4.5]

Eczema is something I’ve had to cope with since infancy along with severe congestion problems. The images of calciphylaxis do not look quite like the itchy patches that I’ve been dealing with for a few months but they resemble the images of calciphylaxis more than they look like the patches of eczema that I’ve had off and on since infancy.

The fun thing about autoimmune disease is all the nifty weird symptoms that you get to experience – and which are so rare that many physicians don’t want to see you or the symptoms in their office –  because those unusual symptoms must be covered by some other specialist’s field. This quote said it well:  Calciphylaxis “is a poorly understood and highly morbid syndrome”. [4]  Maybe I wouldn’t want that syndrome to be my professional responsibility either, and maybe it is just too bad for me that it might be my personal responsibility whether I like it or not. However maybe I’m lucky that my professional and personal experiences have left me more informed about odd symptoms than other health professionals, and therefore I may possibly be better equipped to cope with the odd symptoms.

Thankfully just two days of calcium supplements (while continuing to avoid excess vitamin D and sunshine) have left me feeling less itchy and my open wound areas are beginning to form scabs instead of remaining open wounds with seeping plasma.

In normal physiology the activated hormone form, 1, 25 dihydroxy D, is typically found in elevated amounts only in areas of rapid growth or membrane breakdown, such as in scab formation by white blood cells, [6], and within the placenta during pregnancy. [5] – Maybe elevated 1, 25 dihydroxy D can also be an underlying problem causing calciphylaxis rather than it being due only to deficiency of the inactive vitamin 25-D or the active hormone 1, 25-D.

Yes, my vitamin 25-D level was low at 10.9 ng/mL and anything below 20-30 is considered deficient and I was recommended by my endocrinologist to take vitamin D and calcium. However my hormone 1, 25-D level was 55 pg/mL which is considered within the normal range by mainstream medicine (range: 18-72 pg/mL). Specialists in vitamin D/hormone D metabolism would consider levels of 1, 25-D above 42 pg/mL to be elevated enough to be an osteoporosis risk because above that level the bone cells start releasing calcium, phosphorus, and magnesium into the blood supply instead of absorbing the minerals from circulating plasma and storing them for increased bone strength or for later use. [7]

Calcium and magnesium are so important as electrically active ions that the body has a variety of ways to maintain the blood levels of the two minerals within a narrow range. Blood tests for calcium and magnesium levels may be normal even though there is inadequate dietary intake because the bones can act like a savings account at the bank. In normal health if the blood plasma dips a little low for calcium or magnesium, more minerals are released from the bone, and if levels are getting too elevated than more would be excreted by the kidneys, less would be absorbed by the intestines, and more would be absorbed into the bones for long term storage.

However if 1, 25-D levels are elevated above 42 pg/mL than even if calcium levels were elevated in the blood the abnormally elevated 1, 25-D level would still be telling the bones to release more calcium and for the intestines to absorb more calcium which would lead to way too much calcium for the kidneys to be able to excrete during good health let alone during renal disease (elevated blood calcium would normally signal the body to make more of the enzyme that de-activates 1, 25-D but some microbial pathogens seem to bypass our immune system by disabling our body’s ability to make that enzyme). Adequate magnesium is necessary for the kidneys to be able to excrete calcium and elevated 1, 25-D causes the intestines to preferentially absorb calcium rather than magnesium.

And it turns out that eczema is an autoimmune disease so I may have been trying to figure out how to feel healthier since I was a baby. [8]

My mother gave up trying to spoon feed me. She said I would spit food into my hand, look at it, then put it back into my mouth before swallowing. She put cookie sheets around my highchair to block the mess (and possibly the view) and left me to feed myself from a fairly early age. I still don’t like to be fed by others, whether it’s just a taste of something on a spoon, or whether it is a dietary supplement that might cause my underlying autoimmune condition to worsen.

I’m feeling less itchy and the open wound areas are beginning to heal. The tachycardia problem is better, (having a rapid heart rate with little exercise), and an internal jittery feeling is less. The problem with trying to medicate a nutrient deficiency with psychiatric drugs is that the psychiatric drug can’t take the place of a nutrient in metabolic pathways. For years now physicians, family members and friends have been encouraging me to just take the psychiatric medication as prescribed and stop complaining about psychosomatic symptoms and imaginary problems. But the psychiatric medications that were offered all had bad side effects and while some helped slow down whirling thoughts they didn’t make the thoughts less sad or negative and they didn’t take away the internal feeling of tension.

I felt like a coiled spring internally, very jittery all the time and unable to concentrate as well as normal. I knew something was wrong and I knew feeling like a coiled spring all the time wasn’t an imaginary delusion and the feeling didn’t go away with the three different anti-psychotic medications that physicians or psychiatrists had me try.

We can’t afford ineffective health care as individuals or as a global community. Harsh medications that cause side effects in humans are probably also causing side effects in the health of the environment once the chemicals become waste products. Expensive pharmaceuticals that cause side effects in patients without addressing the person’s underlying condition are primarily helping the pharmaceutical company and may be causing the person’s condition to worsen over the long term.

Low protein intake may be involved as hypoalbuminemia is a risk factor for calciphylaxis. [9 -includes images of calciphylaxis wounds.] I don’t know for sure that my weird skin patches are early stage calciphylaxis wounds but I hadn’t been eating much protein in the weeks before my bruise like symptoms became more like open painful sores and I have probably had a low calcium intake ever since I started limiting my use of dairy products. I did take calcium supplements in the past but my chronic muscle cramps became a problem and the calcium seemed to make it worse. More recently not eating much for a couple weeks would have further reduced my intake of calcium from the sources such as sesame seeds and tree nuts that I normally do eat. Just two days of calcium supplements have helped me feel calm internally instead of jittery (I’m using about 500 mg spread out through the day in low doses). I’m also eating a more adequate amount of protein and other foods and the odd skin patches have less of a burning itchy painful feeling and the areas are starting to heal rather than remain open seeping wounds.

Twenty three and a half to fifty million Americans may have one or more types of autoimmune diseases. [10] So I don’t think that I am the only one who has been regularly told that her symptoms must all be imaginary and to go see a talk therapist or to go get stronger and stronger psychiatric medications. We can’t afford ineffective health care because it doesn’t help the patient and the medications may be bad for the environment once they become waste products. Calcium is a natural mineral that is not harmful to the environment and it is inexpensive.

6/15/15 lab values:

  • Parathyroid hormone level – PTH Intact – 154.1 pg/mL — normal range: [15.0-75.0]
  • Calcium – 8.8 mg/dL — normal range: [8.4-10.2]
  • Phosphorus was not ordered but would probably be good to check.
  • Vitamin D, 25 – 10.9 ng/mL — normal is considered: [30.0-100.0]
  • Vitamin D 1, 25 – 55 pg/mL — normal is considered: [18-72]

I did schedule an appointment with a physician but it will be a few weeks and the tachycardia was not pleasant, the internal coiled spring feeling made it hard to concentrate and hard to not over react to outside events, and the open seeping sores were painful.

I don’t see why I should not try to take care of myself rather than having to follow the orders/recommendations of physicians or psychiatrists when they are working from the premise that “we don’t know what is causing your symptoms or how to cure them but we would really like you to take these harsh medications anyway because we guess that they might reduce some of your symptoms – and please just ignore the negative side effects that the medication is actually adding to your problems because we guess that the medication might help reduce some of the symptoms that you originally came to see us about.” That is an example of circular logic based on guesses and I’m not buying it anymore now than I did when I was sitting in a highchair covered with eczema, milk based formula, and baby food.

Medications can be life saving and certainly are a modern miracle but nutrients will always be our body’s building blocks. Providing medicines to reduce symptoms of nutrient deficiency will only prolong the time the body is left without adequate nutrients and some deficiencies can cause long term damage that is not reversible once the nutrient is added back to the diet. A long term deficiency of Vitamin B12 can cause irreversible nerve damage, [11], and it turns out that calcium or vitamin D deficiency can cause osteoporosis if the deficiency is chronic enough to lead to secondary hyperparathyroidism.

Additional references about risk factors for calciphylaxis in dialysis patients:                   These articles are not mentioned in the text above and the research studies are not about secondary hyperparathyroidism but they do suggest that adequate protein intake may help reduce risk for calciphylaxis and that having elevated phosphorus or alkaline phosphatase levels may increase the risk.

The study group’s parathyroid hormone and albumin levels were not found to be significantly different then the lab values of the control group of dialysis patients who did not have calciphylaxis. The conclusion includes the suggestion that “use of calcium salts as a phosphate binder” during dialysis might have something to do with the increased rate of calciphylaxis that was being seen at dialysis centers at the time.
