- ItemOpen AccessInvestigating kidney disease clinical epidemiology using routinely collected administrative data and proteomics(2024) Aylward, Ryan Edward; Rayner, BrianData collected routinely during healthcare visits and additional biospecimens collected as part of cohort study activities are invaluable to better understand kidney disease epidemiology. This thesis explores the detection and characterization of acute kidney injury (AKI), chronic kidney disease (CKD), acute-on-chronic kidney disease (A-on-CKD) and kidney disease progression using rule-based laboratory- and database-embedded algorithms and proteomic analysis. The research includes three components. Firstly, an internal validation of the National Health Services England (NHSE) AKI detection algorithm-generated alerts received by the United Kingdom Renal Registry. Secondly, a description of the clinical epidemiology of AKI, CKD and A-on-CKD in Cape Town, South Africa, within the Provincial Health Data Centre, a health information exchange that houses administrative and clinical data about clients accessing public healthcare in the province. Lastly, proteins and biological pathways in association with CKD progression in older European adults were investigated (European Quality Study). The implementation of the NHSE AKI detection algorithm in English laboratories was largely successful, though further investigation is required for alerts in people with CKD and alerts from a few outlying laboratories. Overall, the epidemiological findings in Cape Town shed light on the burden and characteristics of AKI, CKD and A-on-CKD in the region and challenges to research with routinely collected data in complex health systems like South Africa. In the EQUAL study, three proteins were associated with eGFR decline, potentially serving as markers of CKD progression and targets for treatment. In conclusion, the digitome (administrative data) and proteome provided unique opportunities for detecting and understanding kidney disease, but limitations such as misclassification, missing data and inability to establish causal relationships were identified, requiring future refinements.
- ItemOpen AccessA practical approach to the nutritional management of chronic kidney disease patients in Cape Town, South Africa(BioMed Central, 2016-07-08) Ameh, Oluwatoyin I; Cilliers, Lynette; Okpechi, Ikechi GBackground: The multi-racial and multi-ethnic population of South Africa has significant variation in their nutritional habits with many black South Africans undergoing a nutritional transition to Western type diets. In this review, we describe our practical approaches to the dietary and nutritional management of chronic kidney disease (CKD) patients in Cape Town, South Africa. Discussion: Due to poverty and socio-economic constraints, significant challenges still exist with regard to achieving the nutritional needs and adequate dietary counselling of many CKD patients (pre-dialysis and dialysis) in South Africa. Inadequate workforce to meet the educational and counselling needs of patients, inability of many patients to effectively come to terms with changing body and metabolic needs due to ongoing kidney disease, issues of adherence to fluid and food restrictions as well as adherence to medications and in some cases the inability to obtain adequate daily food supplies make up some of these challenges. A multi-disciplinary approach (dietitians, nurses and nephrologists) of regularly reminding and educating patients on dietary (especially low protein diets) and nutritional needs is practiced. The South African Renal exchange list consisting of groups of food items with the same nutritional content has been developed as a practical tool to be used by dietitians to convert individualized nutritional prescriptions into meal plan to meet the nutritional needs of patients in South Africa. The list is currently utilized in counselling CKD patients and provides varied options for food items within the same group (exchangeable) as well as offering ease for the description of suitable meal portions (sizes) to our patients. Summary: Regular and continuous education of CKD patients by a multi-disciplinary team in South Africa enables our patients to meet their nutritional goals and retard CKD progression. The South African renal exchange list has proved to be a very useful tool in meeting this need.
