Heterogeneity in patterns of progression of chronic kidney disease.

BACKGROUND: Progression of kidney disease is a deceptively simple word for a complex bio-clinical process, evidenced by the number of definitions in the literature. This has led to confusion and differences in interpretation of studies. METHODS: We describe different patterns of progression, the performance of different definitions of progression and factors associated with chronic kidney disease (CKD) progression in a public renal service in Australia, in a study of patients enrolled in the CKD.QLD Registry with a minimum of 2 years' follow up. RESULTS: Nine patterns of changing estimated glomerular filtration rate (eGFR) over two consecutive 12-month periods were identified. Most common was a stable eGFR over 2 years (30%), and the least was a sustainable improvement of eGFR over both periods (2.1%). There was a lack of congruence between the several definitions of progression of CKD evaluated. More people progressed using the definition of decline of eGFR of >5 mL/min/1.73 m2 /year (year 1 = 30.2%, year 2 = 20.7%) and the least using development of end-stage renal disease (year 1 = 5.4%, year 2 = 9.9%). Age (40-59, ≥80 years), degree of proteinuria at baseline (nephrotic range) and CKD aetiology (renal vascular disease, diabetic nephropathy) were significantly associated with eGFR decline over 2 years. CONCLUSIONS: This is one of the first demonstrations of the great variations among and within individuals in the progression of CKD over even a period as short as 2 years. Findings suggest considerable potential for renal function recovery and stability while demonstrating the importance of using identical definitions for comparisons across datasets from different sources.

Use of Complementary and Alternative Medicines (CAMs) among type 2 diabetes patients in Sri Lanka: a cross sectional survey.

BACKGROUND: The incidence of chronic illnesses has increased worldwide. Diabetes is one such illness and 80% of the diabetic population lives in the developing world. There is a rapidly growing trend towards the use of Complementary and Alternative Medical practices in Diabetes. Sri Lanka is a developing Asian nation with a rich culture of Ayurvedic and native medical culture. The objective of this study was to find the prevalence of use of CAMs in a diabetic population attending a large multiethnic diabetes facility in a University unit and to assess whether there is an increase in the incidence of hypoglycaemic episodes among users of CAMs. METHODS: A cross sectional study was performed at Teaching Hospital Peradeniya between April and August 2012. Following verbal consent, 254 type 2 adult diabetic patients attending the diabetes facility were interviewed regarding the use of CAM and hypoglycaemia using an interviewer-administered questionnaire. RESULTS: Of the 252 valid results, 192 patients (76%) admitted to the use of a CAM to reduce blood glucose. Bitter gourd, ivy gourd and crepe ginger were used by 128, 113 and 92 individuals. While 19% used a single agent, 34%, 21% and 2.4% used 2,3 and more than 3 agents. The incidence of hypoglycaemia in CAM users was 21% and 16.6% in non-users. The difference was statistically not significant. (p = 0.57) Ingestion of Costus speciosus (Crepe ginger) was associated with higher incidence of hypoglycaemia (P = 0.01).Female gender was significantly associated with CAM use (p = 0.01), while the age, duration of diabetes, presence of co-morbidities and complications of diabetes failed to show a significant association. CONCLUSION: Sri Lanka has a very high use of herbal supplementation in type 2 diabetes patients. Although the overall incidence of hypoglycaemia is not increased among CAM users, crepe ginger is associated with significant hypoglycaemia and warrants further research.
