  • Research summary

    It has been claimed that:

    (1) poorly controlled diabetic patients, as judged by high HbA1c levels, have low red blood sialic acid levels and high young red cell (reticulocyte) counts, and
    (2) red cell sialic acid levels decrease with age.

    As part of another study, we have demonstrated a mechanism that might explain these results. However, the previous reports studied only relatively low numbers of patients and we have doubts about some technical aspects of the published studies. We therefore wish to see if we if we can replicate and extend the data. We will measure HbA1c levels and reticulocyte counts in up to 500 individuals, sialic acid levels in a subset of these, and red cell sialic acid levels in a further 100 individuals. We will analyse only samples that are to be discarded after having full blood counts performed in the diagnostic clinical haematology laboratory.
