Dear Editor
In my recent Rapid Response there is a sentence which reads as follows:-
Microcytosis can also be a feature of vitamin B12 deficiency[2],[6], especially when the underlying cause is autoimmune gastritis[7]”
The correct version should be the following:-
“Microcytosis can also be a feature of vitamin B12 deficiency[2],[7], especially when the underlying cause is autoimmune gastritis[7]”
I would also like to take this opportunity to add that, in the context of autoimmune gastritis the association of vitamin B12 deficiency and microcytosis is attributable to coexistence of iron deficiency. Even in other instances of the association of vitamin B12 deficiency and microcytosis it is highly likely that the association is attributable to coexistence of iron deficiency and vitamin B12 deficiency.
