The following article is by Dr John Cannell of the Vitamin D Council.
Dr. Gerry Schwalfenberg of the University of Alberta just published the first case report of a woman with a treacherous autoimmune disorder, idiopathic thrombocytopenic purpura or ITP, that vitamin D apparently cured.
More than 160 known autoimmune disorders exist in humans and more than 5% of the population has at least one of the disorders. They occur when your immune system malfunctions and attacks your own organs or tissues. No known cure exists. In the above publication, Dr. Schwalfenberg reviewed an extensive number of newer medical papers and concluded that, “Evidence that autoimmune disease may be a vitamin D-sensitive disease comes from many sources.”
He then reports on a 48-year-old female with one of the rarest and more perilous autoimmune disorders, ITP, which destroys platelets. Platelets help with blood clotting, and doctors follow platelet counts closely in ITP. She had been ill since 1998, had her spleen taken out to help elevate her platelet count and was on the best medicine for the disease, danazol. However, she continued to suffer from dangerously low platelet counts.
Visible symptoms of ITP include bruises, bleeding from the nostrils, bleeding at the gums, and excessive menstrual bleeding. A very low platelet count may result in blood masses in the mouth or on other mucous membranes. Bleeding time from minor cuts is usually long. Possibly fatal complications include bleeding inside the skull or brain or internal bleeding.
Knowing all the evidence that vitamin D is involved in autoimmune disorders, Dr. Schwalfenberg tested her vitamin D level in 2006 and found it to be 26 ng/ml. He started his patient on 2,000 IU of vitamin D per day. Her platelet count increased but not to normal. For the next two years, she had no symptoms of her ITP except for a moderately low platelet count. Unfortunately, a neighbor told her that 2,000 IU/day would make her toxic, so she stopped the vitamin D and her platelet count promptly fell dangerously low.
Dr. Schwalfenberg reassured her that her neighbor was incorrect and restarted her vitamin D, this time at 4,000 IU/day. She did well, and for the first time in a decade, was able to stop her danazol. She was given 10,000 IU/day of vitamin D for several days for an upper respiratory infection and her platelet count became normal for the first time in 14 years. It remains normal to this day and she is doing fine with a vitamin D level of 40 ng/ml taking 4,000 IU/day.
