Background
Vascular complications are the major cause of morbidity and mortality in diabetic patients. These can result from interactions between systemic metabolic abnormalities, such as hyperglycemia, dyslipidemia, genetic and epigenetic modulators, and local tissue responses to toxic metabolites.
Aim of the Work
To assess the role of PTX3 as an early marker of vascular complications in children and adolescents with type 1 diabetes mellitus and its correlation with metabolic control and its relation to hsCRP level.
Patients and Methods
Fifty adolescents with type 1 diabetes mellitus and 40 age and sex matched control group, Detailed history taking, full systemic examination were done, Patients also were investigated using HbA1c, lipid profile, ALT, Alb/Cr ratio in urine, PTX3, hsCRP and carotid intima media thickness (CIMT). An informed consent was obtained from patients, controls or their legal guardians before enrollment in the study.
Inclusion criteria
Patients with type 1 diabetes their age ranging from 5 to 18 years old with at least 5 years disease duration and on regular clinic visits and multiple daily insulin therapy .
Exclusion criteria
Patients with proven vascular complications and those with any clinical evidence of infection, hematological diseases, tumors, liver dysfunction, urinary tract disorders, connective tissue disease, or other autoimmune diseases, also patients with morbid obesity were excluded.
Results
PTX3 and hsCRP were significantly higher in patients compared to control group. A significant positive correlation between serum PTX3 and level of HbA1c%, level of Triglycerides (TG), level of Total Cholesterol was observed. Additionally, PTX3 and hsCRP levels were elevated in patients with elevated lipid profile (TG and Cholesterol) and high HbA1c% level in comparison with those with normal lipid profile and those with controlled HbA1c% level (p < 0.001). No significant difference was found between patients and control groups as regard CIMT.
Conclusion
. The increased levels of PTX3 and hsCRP in patients with uncontrolled diabetes even before development of both microvascular and macrovascular complications add a promising tool for their follow up and applying early protective measures.
