Introduction:

Type 2 diabetes mellitus is characterized by hyperglycemia due to insufficient insulin production by β cells. Myeloperoxidase promotes oxidative stress during inflammation and ceruloplasmin is considered its endogenous inhibitor.

Objective:

To evaluate the relationship between ceruloplasmin and myeloperoxidase, determined simultaneously in the serum of type 2 diabetic patients.

Methods:

A total of 362 type 2 diabetic patients and 110 healthy subjects were studied. Serum ceruloplasmin activity was determined by the Siotto KM method and myeloperoxidase by the Kraeisz JE method.

Results:

72% of diabetic patients had hyperglycemia and 77% had abdominal obesity. The activities of both enzymes were significantly increased relative to the control group. The correlation coefficient of enzyme activity was low. The ORMO/CP ratio of diabetic patients exceeded that of controls. Ceruloplasmin did not inhibit myeloperoxidase.

Conclusions:

Myeloperoxidase predominated, therefore, the inhibitory effect of ceruloplasmin was not manifested. The high activity of myeloperoxidase was associated with a worsening of the clinical picture of the diabetic patient.
