Type 2 & other diabetes

The association between inflammation and glucose levels in hospitalised patients with type 2 diabetes

Diabetes Obes MetabPublished Post hoc analysis of the DIATEC randomised controlled trial

Authors' conclusion

Elevated CRP levels only modestly increased glucose levels. This suggests that inflammation during hospitalisation has a limited effect on glucose levels in non-ICU patients with type 2 diabetes.

Study context

Population
Non-ICU hospitalised patients with T2D treated with basal-bolus insulin, managed with rtCGM or point-of-care glucose testingDIATEC trial
Participants
166 participants
Comparison
Association of daily C-reactive protein (CRP) with daily glycaemic outcomes and insulin doses

Primary result

As reported in the abstract

Association of CRP with glycaemic outcomes · daily

Change in TIR 3.9-10.0 mmol/L (70-180 mg/dL) per 100 mg/dL CRP increase: decrease, %-points

3.6

95% CI 1.2–6.1p = 0.004

Change in TIR with interaction of high CRP (>75.0 mg/dL) and high HbA1c (>51.0 mmol/mol or 6.8%): reduction, %-points

8.9

95% CI 3.8–14.1

Change in TAR >10.0 mmol/L (>180 mg/dL) per 100 mg/dL CRP increase: increase, %-points

3.3

95% CI 0.8–5.8p = 0.009

Change in mean glucose per 100 mg/dL CRP increase: increase, mmol/L (95% CI 0.02-0.4)

4.0 mg/dL 0.2

95% CI 0.4–7.0
