title: Cardiovascular and cerebrovascular comorbidities in hemodialysis patients from the Gulf Cooperation Council countries enrolled in the dialysis outcome and practice pattern study phase 5 (2012-2015).
abstract: To determine the prevalence of cardiovascular comorbidities and their active risk factors in the selected hemodialysis centers in the Gulf Cooperation Council (GCC) countries, the Dialysis Outcome and Practice Pattern Study (DOPPS) was performed on 40 dialysis centers in the six GCC countries from June 2012 to May 2015. There were 21 dialysis centers from Saudi Arabia, nine from the United Arab Emirates (UAE), four from Kuwait, four from Oman, two from Qatar, and one from Bahrain. There were 922 patients participating in the study; 419 patients from Saudi Arabia, 144 from the UAE, 164 from Kuwait, 89 from Oman, 58 from Qatar, and 25 from Bahrain. Baseline data and laboratory investigations were obtained from every study patient, and the patients with any new events, change of dialysis prescription, or death were reported to the DOPPS main center during follow-up. The median age of the patients in the GCC centers was 55 years (range 32- 80 years), and the median percentage of males was 57%. The most common cause of chronic kidney disease among the study patients was diabetes mellitus (median: 43%) followed by hypertension (median: 29%) and glomerulonephritis (median: 9%). Hypertension (median 90%) and diabetes mellitus (median 52%) were the most common predisposing comorbidities to cardiovascular events in the study patients. The median ratios of patients with coronary artery disease, peripheral vascular disease, and congestive heart failure were 34%, 23%, and 24%, respectively. The median ratio for cerebrovascular comorbidities was 9%. The median prevalence of the factors that may predispose to the cardiovascular and cerebrovascular comorbidities such as gender of the patients, adequacy of dialysis, diabetes, hypertension, hypercholesterolemia, levels of anemia, parathormone levels, and calcium and phosphorus levels in the GCC countries were comparable with those in the previous DOPPS in other countries.
