Higher systemic inflammatory status and cardiovascular risk associated with Charcot arthropathy unrelated to infection or extremity amputation.

PURPOSE

People with diabetes and Charcot arthropathy have higher mortality than people with diabetes without this complication. Are the causes of this higher mortality exclusively infectious or of a cardiovascular origin? We aimed to study aspects related to cardiovascular risk and inflammation in a population of people with type 2 diabetes with and without Charcot arthropathy.

METHODS

A cross-sectional study was performed in people with diabetes and Charcot Eickenholtz III arthropathy, matched for sex and age, with two groups of people with diabetes without Charcot arthropathy with and without peripheral sensory-motor neuropathy, in the absence of active infection. All participants underwent clinical and laboratory evaluation at the time of the interview, and their cardiovascular risk was calculated according to the United Kingdom Prospective Diabetes Study (UKPDS) calculator.

RESULTS

We evaluated 69 people with type 2 diabetes (21 with Charcot arthropathy, 24 with diabetic peripheral neuropathy and 24 without this neuropathy), with a mean age between 57 and 61 years and with a diabetes duration of more than 10 years. Patients with Charcot arthropathy had a longer duration of diabetes; more frequency of dyslipidemia; and higher levels of uric acid, microalbuminuria and C-reactive protein than the other two groups. A total of 73.9% of the people evaluated had high or very high cardiovascular risk according to the UKPDS score.

CONCLUSION

The people with type 2 diabetes presenting Charcot arthropathy had greater values of systemic inflammatory parameters, even in the chronic phase of the complication, with a higher risk of mortality unrelated to infections.
