Preventing End Stage Kidney Failure Part 4

Posted on May 1, 2010 at 10:35 PM

A kidney contains about one million nephrons, which are the filtration systems of the body. They regulate the amount of water, salts, glucose, urea and other crucial minerals.

One of the most important measurements of kidney function is called the glomerular filtration rate (GFR). The glomerular filtration rate is commonly derived from a formula in which age, sex, race, and plasma creatinine are relevant variables. GFR above 90 milliliters per minute is normal, and below 15 denotes end stage kidney disease.

An issue of vicious cycle causation is elevated homocysteine in the blood, which not only contributes to atherosclerosis, but can bring on kidney failure. This cycle allows homocysteine to build up even higher, causing more atherosclerosis.

An unfortunate paradox of end stage kidney disease is that homocysteine lowering B-vitamins such as B6, folate and B12 can actually worsen it. Based on research conducted at five university medical centres.

The water solubility of B-vitamins is easily excretable in healthy people, however those with kidney failure may not be able to do so based on adverse effects observed in the research. Therefore, using heavy metal chelation such as OSR, should first be used until kidney health is strong enough to handle taking supplemental B-vitamins.

As the kidney improves with heavy metal chelation, the root of elevated homocysteine may stablize, and if it does successfully, the thyroid gland may also improve. The state of the thyroid is intimately involved in the regulation of homocysteine, thus treating the cause of homocysteine elevation maybe a key to success.

Conversely, limiting treatment to lowering homocysteine only, for chronic kidney disease does not improve outcome.

The kidney normally plays an important role in the metabolism, degradation, and excretion of several thyroid hormones. It is not surprising therefore that impairment in kidney function leads to disturbed thyroid physiology.

Failing kidney function results in all levels of hypothalamic-pituitary-thyroid axis faltering, including alterations in hormone production, distribution, and excretion. This means with an expectation of improvement of kidney function, hormone balance will improve accordingly.

If kidney health becomes severe, it may bring on secondary hyperparathyroidism, due to problems with the ability to break down and remove phosphate. A patient at this time may also need the active form of vitamin D, called calicitriol as it may lose the ability to synthesize vitamin D on its own.

Careful controlled doses of the active form of vitamin D or pre-formed, such as calcitriol and alfacalcidol can be administered to those with chronic kidney disease (CKD).

As mentioned earlier, atherosclerosis can bring on kidney failure. Atherosclerosis in the peripheral arteries implies atherosclerosis elsewhere, and in such places when poor circulation occurs in the kidneys, it is the hallmark of chronic kidney failure and, ultimately, end-stage kidney disease.

So while metal chelation and Benfotiamine can allow the kidneys to recover, amongst other important nutritional considerations depending upon the stage, there is another nutrient to help prevent the dreaded possibility of hemodialysis, the mechanical, man-made version of the kidney.

Despite the normal role that water soluble B-vitamins provide to lower homocysteine levels, they are of no use in end stage kidney disease, and as stated before, can make things only worse, despite lowering homocysteine levels.

The alternative is the use of propionyl-L-carnitine (PLC), which not only lowers homocysteine, it also lowers endothelin-1, which constricts the arteries. As the kidneys begin to deteriorate, they produce diminishing quantities of the amino acid, carnitine. Taking either acetyl-L-carnitine (ALC) or propionyl-L-carnitine (PLC) can help protect the kidney and are more bioavailable than regular L-carnitine.

An excellent addition to PLC or ALC carnitine is Lipoic acid. Lipoic acid is an ideal, natural compound that augments kidney protection. Lipoic acid is both water and fat soluble, therefore it is widely distributed in all tissue.

Lipoic acid scavenges hydroxyl radicals, hypochlorous acid and singlet oxygen while exerting transitional metal chelation. Vitamin C is often shunned in kidney treatments due to concerns over oxalate stones, so it is helpful that

lipoic acid "recycles" endogenous antioxidants such as Vitamin C and E.

Several clinical studies have shown lipoic acid as a therapeutic agent for such diverse conditions as diabetes, atherosclerosis, insulin resistance, neuropathy, which in part are all related to kidney function.

It is important to note that the synthetic antioxidant, Oxidative Stress Relief (OSR), should be taken at least 4-hours apart from lipoic acid.

In the next Daily Topic, will conclude some final treatment options and considerations to help prevent end stage kidney failure.
