Patient Prefer Adherence
August 2016
Objectives: Nonadherence to antihypertensive medications has not been assessed in the Saudi population. The aim of this study was to address and evaluate the magnitude of nonadherence among hypertensive patients and the risk factors associated with it.
Methods: A cross-sectional survey was conducted on hypertensive patients who attended the general internal medicine clinics at King Abdulaziz Medical City, Riyadh, Saudi Arabia, using a questionnaire that was modified after reviewing the literature.
Background: In patients with SCD, the spleen commonly enlarges during the first two decades of life but then undergoes autosplenectomy due to repeated attacks of vaso-occlusion and infarction. This, however, is not the case in Saudi patients with SCD, where splenomegaly sometimes persists into adult life.
Patients And Methods: Ultrasonography was used to evaluate spleen size in 363 Saudi patients with SCD (340 SCD and 23 sickle I(2)-thalassemia).
