Background The effects of the sodium-glucose co-transporter-2 inhibitor empagliflozin on renal and cardiovascular disease have not been tested in a dedicated population of people with chronic kidney disease (CKD). Methods The EMPA-KIDNEY trial is an international randomized, double-blind, placebo-controlled trial assessing whether empagliflozin 10 mg daily reduces risk of kidney disease progression or cardiovascular death in people with CKD. People with or without diabetes mellitus (DM) were eligible provided they had: (i) an estimated glomerular filtration rate (eGFR) ≥20, <45 mL/min/1.73m2; or (ii) an eGFR ≥ 45, <90 mL/min/1.73m2 with a urinary albumin: creatinine ratio (uACR) ≥200 mg/g. The trial design is streamlined: extra work for collaborating sites is kept to a minimum, and only essential information is collected. Results Between 15 May 2019 and 16 April 2021, 6609 people from eight countries in Europe, North America and East Asia were randomized. Mean age at randomization was 63.8 (SD 13.9) years, 2192 (33%) were female, and 3570 (54%) had no prior history of DM. Mean eGFR was 37.5 (14.8) mL/min/1.73m2, including 5185 (78%) with an eGFR < 45 mL/min/1.73m2. Median (Q1-Q3) uACR was 412 (94–1190) mg/g, with a uACR < 300 mg/g in 3194 (48%). The causes of kidney disease included diabetic kidney disease (n = 2057 [31%]), glomerular disease (n = 1669 [25%]), hypertensive/renovascular disease (n = 1445 [22%]), other (n = 808 [12%]), and unknown causes (n = 630 [10%]). Conclusions EMPA-KIDNEY will evaluate the efficacy and safety of empagliflozin in a widely generalizable population of people with CKD at risk of kidney disease progression. Results are anticipated in 2022.
Background Ileus is common after elective colorectal surgery, and is associated with increased adverse events and prolonged hospital stay. The aim was to assess the role of non‐steroidal anti‐inflammatory drugs (NSAIDs) for reducing ileus after surgery. Methods A prospective multicentre cohort study was delivered by an international, student‐ and trainee‐led collaborative group. Adult patients undergoing elective colorectal resection between January and April 2018 were included. The primary outcome was time to gastrointestinal recovery, measured using a composite measure of bowel function and tolerance to oral intake. The impact of NSAIDs was explored using Cox regression analyses, including the results of a centre‐specific survey of compliance to enhanced recovery principles. Secondary safety outcomes included anastomotic leak rate and acute kidney injury. Results A total of 4164 patients were included, with a median age of 68 (i.q.r. 57–75) years (54·9 per cent men). Some 1153 (27·7 per cent) received NSAIDs on postoperative days 1–3, of whom 1061 (92·0 per cent) received non‐selective cyclo‐oxygenase inhibitors. After adjustment for baseline differences, the mean time to gastrointestinal recovery did not differ significantly between patients who received NSAIDs and those who did not (4·6 versus 4·8 days; hazard ratio 1·04, 95 per cent c.i. 0·96 to 1·12; P = 0·360). There were no significant differences in anastomotic leak rate (5·4 versus 4·6 per cent; P = 0·349) or acute kidney injury (14·3 versus 13·8 per cent; P = 0·666) between the groups. Significantly fewer patients receiving NSAIDs required strong opioid analgesia (35·3 versus 56·7 per cent; P < 0·001). Conclusion NSAIDs did not reduce the time for gastrointestinal recovery after colorectal surgery, but they were safe and associated with reduced postoperative opioid requirement.
Background: It is well established that decreased kidney function can increase blood pressure (BP), but it is unproven whether moderately elevated BP causes chronic kidney disease (CKD) or glomerular hyperfiltration. Methods: Three hundred eleven thousand one hundred nineteen White British UK Biobank participants were included in logistic regression analyses to estimate the odds of CKD (defined as long-term kidney replacement therapy, estimated glomerular filtration rate [eGFR]<60 mL (min·1.73m 2 ), or urinary albumin:creatinine ratio ≥3 mg/mmol) associated with higher genetically predicted BP using genetic risk scores comprising 219 systolic and 223 diastolic BP loci. Analyses estimating associations with clinical categories of eGFR and urinary albumin:creatinine ratio were also conducted, with an eGFR ≥120 mL (min·1.73m 2 ) considered evidence of glomerular hyperfiltration. Results: Twenty-one thousand six hundred twenty-three participants had CKD: 7781 with reduced eGFR and 15 500 with albuminuria. One thousand eight hundred twenty-eight participants had an eGFR ≥120 mL (min·1.73m 2 ). Each genetically predicted 10 mm Hg higher systolic BP and 5 mm Hg higher diastolic BP were associated with a 37% (95% CI, 1.29–1.45) and 19% (1.14–1.25) higher odds of CKD, respectively. Associations were evident for both the reduced eGFR and albuminuria components of the CKD outcome. The odds of hyperfiltration (versus an eGFR ≥60 and <90 mL[min·1.73m2]) were 49% higher (95% CI, 1.21–1.84) for each genetically predicted 10 mm Hg higher systolic BP. Associations with CKD and hyperfiltration were similar irrespective of preexisting diabetes, vascular disease, or different levels of adiposity. Conclusions: In this general population, genetic epidemiological evidence supports a causal role of life-long differences in BP for decreased kidney function, glomerular hyperfiltration, and albuminuria. Physiological autoregulation may not afford complete renal protection against the moderate BP elevations.
