Treating Pernicious Anaemia
Until the 1920’s people who were diagnosed with Pernicious Anaemia died, often after many years of suffering. The first treatments used liver therapy. Patients were fed raw, or very lightly cooked liver several times a day. The liver could be fried, grilled or made into liver drinks. Later, liver injections became available and in the late 1940’s artificially produced B12 became available.
Injections are still the preferred method of treating Pernicious Anaemia.
Here’s what the new Guidelines for Cobalamin (B12) and Folate Disorders issued by the British Committee for Standards in Haematology say:
…the efficacy and cost–effectiveness of oral treatment in wider population-based settings has yet to be established. There are arguments against the use of oral cobalamin in initiation of cobalamin therapy in severely deficient individuals who have poor absorption, especially due to pernicious anaemia.
High dose oral cobalamin would be a reasonable alternative as maintenance in patients unable to tolerate intramuscular injections provided there is good compliance with treatment. On the other hand, some patients may prefer intramuscular injection therapy in order to assure effective treatment.
The frequency of injections varies from country to country. In the UK this is usually a 1mg/ml injection every three months though many doctors prescribe more frequent injections.
Those injections used to be given every month in the 1960’s but this was changed to every two months in the 1970’s and to every three months in 1984.
The frequency of injections is the most common cause of complaint by members of this society and when doctors refuse to prescribe more frequent injections the patient often has to find alternative sources in order to supplement more frequently.
Nobody knows why some patients need more frequent injections than others though there are a number of hypotheses as to why this is so. This society is currently working with a team of researchers to investigate this thoroughly.
BE AWARE – taking supplements that contain B12 will affect any tests ordered by your doctor to assess your B12 status. You should not take any supplement before having your B12 assessed and/or having the test to find out if you have the Intrinsic Factor Antibody.
