Abstract

BACKGROUND : Serum Pentraxin3 Level As A recent Biomarker Of Diabetic Retinopathy In Egyptian patients with diabetes.
OBJECTIVE : To evaluate the association between elevated levels of plasma pentraxin 3 and the development and/or progression of diabetic retinopathy.
METHODS : and methods: This case control study was carried out in internal medicine department, outpatient clinic of internal medicine and outpatient clinic of ophthalmology, at Zagazig university Hospital, 2018. Serum PTX3 level, HsCRP, HbA1c, lipid profile, serum creatinine were determined in 20 normal subjects, 20 patients with prediabetes, 20 patients with diabetes without diabetic retinopathy (DR), 20 patients with non-proliferative diabetic retinopathy (NPDR) and 20 patients with proliferative diabetic retinopathy (PDR).
RESULTS : Serum PTX3 level significantly increased in patients with DR more than patients without DR with cut off point 1150 pg/ml, sensitivity 93.3%and specificity 72%. Serum HsCRP level significantly increased in patients with DR more than patients without DR with cut off point of 7.60 pg/ml has sensitivity 93.3% and specificity 68%.. Combined use of PTX3 and HsCRP decreases sensitivity to 76.7%, but combined use increases specificity to 90%.Significant relation between poor glycemic control and development of DR and its severity as showed by HbA1c.
CONCLUSIONS : Serum PTX3 levels mayt have significant role in the development of DR and its severity. Serum HsCRP increased with DR progression. Poor glycemic control significantly associated with high incidence of diabetic retinopathy and its severity. Longer diabetes duration is associated with progression of DR.
