Prothrombotic Changes in Patients with End-Stage Renal Disease and its Relation to Thrombotic Cardiovascular Complication
Keywords:End stage renal disease, Antithrombin, Factor XII activity, plasma Fibrinogen, coagulation parameters
Background: There is a great risk of cardiovascular disease (CVD) and vascular thrombosis in patients
with End-Stage Renal Disease (ESRD). These patients exhibit numerous abnormalities in coagulation,
fibrinolytic, inhibitory protein abnormalities in multiple levels.
Aim: To assess hypercoagulable changes by measuring the levels of Antithrombin, plasma fibrinogen
and FXII activity in patients with ESRD, and to found correlation between and hematological parameters
including: Hb level, WBC count, reticulocyte percentage and platelet count.
Method: A case control study conducted at Al-Hayat center, Al Karama teaching hospital during the period
from the 1 of February to the 30 of October 2014 and 50 patients aged < 60 years of both genders with
(ESRD) in addition to 20 apparently healthy controls were included in this study.
Results: Patients and controls were matched for age and gender. The mean hemoglobin level, total WBC
count, absolute neutrophil count, reticulocyte percentage and platelets count were significantly lower in
ESRD patients than controls, P<0.05. The mean values of the coagulation parameters, ProthrombinTtime
(PT), Activated Partial Thromboplastin Time (APTT), Plasma Fibrinogen and Factor XII activity were
significantly higher in patients than controls. Anti-thrombin activity was significantly lower in patients
group than controls, (P<0.001). Cardiovascular complications and vascular thrombosis included Deep
Venous Thrombosis( DVT), Cerebro-Vascular-Accident (CVA), Myocardial Infarction (MI), angina or heart
failure reported in 62% of the patients. Patients with cardiovascular complication and vascular thrombosis
had significantly higher PT, APTT, and factor XII activity, lower anti-thrombin activity as compared to those
without cardiovascular complication and vascular thrombosis.
Conclusion: (ESRD) patients had coagulation abnormalities render them more liable to have cardiovascular
complications and vascular thrombosis.
