Poorly controlled type 2 diabetes patients with self-monitoring of blood glucose protocol have been shown to decrease high-sensitivity C-reactive protein levels….
To examine the effect of a structured SMBG protocol associated decrease in A1c on the changes in hs-CRP, Oliver Schnell, from the Helmholtz Center Munich, and colleagues conducted a randomized study on 483 poorly-controlled insulin-naïve patients with type 2 diabetes. Participants were randomized to either an active control (ACG) or structured testing (STG).
The results of the study showed that at 3, 6, 12 months, the reductions in hs-CRP for the STG group were greater than the ACG group. In patients with high cardiovascular risk, the hs-CRP was lower in the STG group than the ACG group. Both groups showed a strong relationship between decreases in hs-CRP and hemoglobin A1c.
The authors state, "Our study is the first to report a relationship between the significant glycemic outcomes of a structured SMBG intervention and changes in hs-CRP, a clinical marker of cardiovascular risk.
