Talk:Vitamin B12 deficiency

New form of B12 deficiency discovered
Very interesting, at the preprint site MedRxiv: Transcobalamin Receptor Autoantibodies in Central Vitamin B12 Deficiency. The list of authors looks impressive, thus I guess it will be published eventually. The authors say that the newly-discovered disease is similar in its mechanisms to the autoantibody-induced form of cerebral folate deficiency. Antibodies thwart the transport of the vitamin to the central nervous system, and the blood levels of the vitamin remain misleadingly normal. Cheers, --CopperKettle (talk) 10:16, 26 August 2023 (UTC)
 * It has been published: Transcobalamin receptor antibodies in autoimmune vitamin B12 central deficiency - Pluvinage et al., 26 Jun 2024 -- Maybe it will be worthwile to mention it, or even to start a standalone article -- Cheers, --CopperKettle (talk) 05:40, 28 June 2024 (UTC)

Mycobacterium tuberculosis infection as cause of B12 deficiency
It's well established that M. Tuberculosis is dependent on vitamin B12 and deficiency of B12 in organism is common in TB patients.. Some limited studies suggest it as a biomarker of TB treatment. I sugget to mention this fact. AXO NOV (talk) ⚑ 16:46, 13 March 2024 (UTC)
