Top in endocrinology: Low vitamin D can dampen vaccine response; HbA1c values questioned

Adults with vitamin D deficiency had lower COVID-19 vaccine antibody titers than adults with normal vitamin D levels 9 months after vaccination, according to a brief report in Endocrine.
Researchers suggested supplementing vitamin D before vaccination if patients are deficient to improve their long-term response to the shot.
It was the top story in endocrinology last week.
The second top story was about a retrospective study that found that Black patients with diabetes have a higher HbA1c than white patients with the same mean glucose. One researcher told Healio that relying solely on elevated HbA1c levels could lead to premature diagnoses of diabetes or overtreatment.
