Medscape reported on Thursday that higher A1c levels are associated with a greater number of deaths among people with diabetes related to cystic fibrosis. The finding concerns the form of diabetes that develops in some people with cystic fibrosis, a genetic condition affecting the lungs and other organs.
According to Medscape, the link points to blood sugar control as a factor connected to mortality in this patient group. The report frames elevated A1c — a measure of average blood glucose over time — as tied to worse survival outcomes.
The reporting did not provide further detail on the size of the study, the population examined, or the specific risk figures involved. Medscape's headline and summary present the association as the central finding, without additional data on how the relationship was measured or adjusted.
Cystic fibrosis-related diabetes is a distinct category of diabetes, separate from type 1 and type 2, and it is managed with attention to both lung health and glucose control. The Medscape report adds mortality to the outcomes linked with A1c in this group.
Because the available material is limited to the headline and summary, the precise strength of the association and the study design behind it remain unclear from this report alone.
What to watch next: whether Medscape or the underlying research team publishes fuller results, including study size and the mortality figures behind the association.
