Hi Guys
I have had such an extraordinary week chatting with you on this forum that my head is buzzing with PA questions!
I am having a PA review and research day today.
I am revisiting "What you need to know about PERNICIOUS ANAEMIA AND B12 DEFICIENCY" by our wonderful Martyn Hooper. The following paragraph on page 143 struck a cord in relation to this week's exchanges about frequency of self-treatment:
"In other words, the patients who were given large doses initially needed large doses for maintenance, while those who were started off on small doses only needed small doses in the future. Now why could that be? Often when modern-day patients ask for more frequent injections they are told that 'the more you receive the more you want' which, as far as I've [Martyn Hooper] been able to discover is based on no scientific evidence, but is a way of telling the patient that he or she is imagining that they need more injections. But the 1958 paper was not based on patient's feeling of wellbeing but instead on close inspection of the patient's blood. And patients who were given large doses initially needed large doses for maintenance, not to feel well, but to prevent their blood deteriorating. Why this was the case is not explained by the researchers and I [Martyn Hooper] haven't been able to find any papers that re-examine this phenomenon." Note my (wwwdot) emphasis in bold type and addition in [].
(The 1958 paper is Darby WJ, Bridgeforth EB, Le Brocquy J, Clark SL Jr, De Oliveira JD, Kevany J, McGanity WJ, Perez C. Vitamin B12 requirements of adult man. American Journal of Medicine 1958; 25(5):726-732)
This certainly puts our recent discussions and experimentation with frequency of injections into context.
