PREVALENCE OF PERIPHERAL ARTERIAL DISEASE AMONG HEMODIALYSIS PATIENTS

Abstract

Background: Peripheral arterial disease (PAD) is common in patients with end-stage renal disease on hemodialysis, but is frequently underdiagnosed. The risk factors for PAD are well known within the general population, but they differ somewhat in hemodialysis patients. This study aimed to determine the prevalence of PAD and its risk factors in patients on hemodialysis. Objective: To assess the prevalence of peripheral arterial disease in end stage renal disease patients on hemodialysis. Patients and Methods: This was across-sectional study carried out at Hemodialysis Unit of Al-Hussein University Hospital over a period of six month; from September 2019 to April 2020, and conducted on 80 hemodialysis patients. Demographic data and clinical information were recorded. Laboratory data including CBC, calcium, phosphate, total cholesterol, triglyceride, high-density lipoprotein, and iron profile were evaluated. The ankle-brachial index was measured in all patients. PAD was diagnosed if ankle-brachial index 0.9. Results: As regard description of demographic data, the mean age of all studied patients was 45.3 ± 8.8 years with minimum age of 24 years and maximum age of 62 years. There were 43 males (53.8%) and 37 females (46.3%). Thirty-five patients (43.7%) were diabetic, and 48 patients (60%) were hypertensive. According to laboratory profile, the mean of WBCs, Hb, platelets, serum calcium, PO4, and iPTH were 6.5 x10³/ul, 10.4 g/dl, 228.2 x10³/ul, 8.3 mg/dl, 9.4 mg/dl and 477.2 ug/ml respectively. Regarding lipid profile, the mean of total cholesterol, HDL and triglyceride were 214.7 mg/dL, 41.9 mg/dL,and 172.2 mg/dL, respectively. Regarding to iron profile, the mean of iron serum, ferritin and TIBC were 62.7 mg/dl, 603.3 ng/ml and 236.7 mg/dl, respectively. According to ABI, there were 22 patients (27.5%) ≤ 0.9, while there were 58 patients (72.5%) > 0.9. The prevalence of peripheral arterial disease among HD patients was 27.5%. Conclusions: High prevalence of peripheral arterial disease in CKD patients on hemodialysis and Ankle –brachial index was clearly more sensitive than physical examination in detecting of peripheral arterial disease in CKD patients on hemodialysis.
