Prevention of renal failure: the Malaysian experience

Hooi LS, Wong HS, Morad Z

Kidney Int Suppl, 2005 Apr.
PMID: 15752245

Renal replacement therapy in Malaysia has shown exponential growth since 1990. The dialysis acceptance rate for 2003 was 80 per million population, prevalence 391 per million population. There are now more than 10,000 patients on dialysis. This growth is proportional to the growth in gross domestic product (GDP). Improvement in nephrology and urology services with widespread availability of ultrasonography and renal pathology has improved care of renal patients. Proper management of renal stone disease, lupus nephritis, and acute renal failure has decreased these as causes of end-stage renal disease (ESRD) in younger age groups. Older patients are being accepted for dialysis, and 51% of new patients on dialysis were diabetic in 2003. The prevalence of diabetes is rising in the country (presently 7%); glycemic control of such patients is suboptimal. Thirty-three percent of adult Malaysians are hypertensive and blood pressure control is poor (6%). There is a national coordinating committee to oversee the control of diabetes and hypertension in the country. Primary care clinics have been provided with kits to detect microalbuminuria, and ACE inhibitors for the treatment of hypertension and diabetic nephropathy. Prevention of renal failure workshops targeted at primary care doctors have been launched, opportunistic screening at health clinics is being carried out, and public education targeting high-risk groups is ongoing. The challenge in Malaysia is to stem the rising tide of diabetic ESRD.

Fulltext Fish oil and aspirin effects on arteriovenous fistula function: Secondary outcomes of the randomised omega-3 fatty acids (Fish oils) and Aspirin in Vascular access OUtcomes in REnal Disease (FAVOURED) trial

PMID: 30913208 DOI: 10.1371/journal.pone.0213274

BACKGROUND: Arteriovenous fistulas (AVF) for haemodialysis often experience early thrombosis and maturation failure requiring intervention and/or central venous catheter (CVC) placement. This secondary and exploratory analysis of the FAVOURED study determined whether omega-3 fatty acids (fish oils) or aspirin affected AVF usability, intervention rates and CVC requirements.
METHODS: In 567 adult participants planned for AVF creation, all were randomised to fish oil (4g/d) or placebo, and 406 to aspirin (100mg/d) or placebo, starting one day pre-surgery and continued for three months. Outcomes evaluated within 12 months included AVF intervention rates, CVC exposure, late dialysis suitability failure, and times to primary patency loss, abandonment and successful cannulation.
RESULTS: Final analyses included 536 participants randomised to fish oil or placebo (mean age 55 years, 64% male, 45% diabetic) and 388 randomised to aspirin or placebo. Compared with placebo, fish oil reduced intervention rates (0.82 vs 1.14/1000 patient-days, incidence rate ratio [IRR] 0.72, 95% confidence interval [CI] 0.54-0.97), particularly interventions for acute thrombosis (0.09 vs 0.17/1000 patient-days, IRR 0.53, 95% CI 0.34-0.84). Aspirin significantly reduced rescue intervention rates (IRR 0.45, 95% CI 0.27-0.78). Neither agent significantly affected CVC exposure, late dialysis suitability failure or time to primary patency loss, AVF abandonment or successful cannulation.
CONCLUSION: Although fish oil and low-dose aspirin given for 3 months reduced intervention rates in newly created AVF, they had no significant effects on CVC exposure, AVF usability and time to primary patency loss or access abandonment. Reduction in access interventions benefits patients, reduces costs and warrants further study.

Fulltext Renal, cardiovascular and safety outcomes of canagliflozin in patients with type 2 diabetes and nephropathy in East and South-East Asian countries: Results from the Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation Trial

AIMS/INTRODUCTION: The sodium-glucose cotransporter 2 inhibitor, canagliflozin, reduced kidney failure and cardiovascular events in the Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation (CREDENCE) trial. We carried out a post-hoc analysis to evaluate the efficacy and safety of canagliflozin in a subgroup of participants in East and South-East Asian (EA) countries who are at high risk of renal complications.
MATERIALS AND METHODS: Participants with an estimated glomerular filtration rate of 30 to <90 mL/min/1.73 m2 and urinary albumin-to-creatinine ratio of >300-5,000 mg/g were randomized to 100 mg of canagliflozin or a placebo. The effects of canagliflozin treatment on pre-specified efficacy and safety outcomes were examined using Cox proportional hazards regression between participants from EA countries (China, Japan, Malaysia, the Philippines, South Korea and Taiwan) and the remaining participants.
RESULTS: Of 4,401 participants, 604 (13.7%) were from EA countries; 301 and 303 were assigned to the canagliflozin and placebo groups, respectively. Canagliflozin lowered the risk of primary outcome (composite of end-stage kidney disease, doubling of serum creatinine level, or renal or cardiovascular death) in EA participants (hazard ratio 0.54, 95% confidence interval 0.35-0.84). The effects of canagliflozin on renal and cardiovascular outcomes in EA participants were generally similar to those of the remaining participants. Safety outcomes were similar between the EA and non-EA participants.
CONCLUSIONS: In the CREDENCE trial, the risk of renal and cardiovascular events was safely reduced in participants from EA countries at high risk of renal events.
