SGLT2 Inhibitor Protected for Kidneys in Hospitalized COVID Sufferers
Taking sodium-glucose cotransporter-2 (SGLT2) inhibitor dapagliflozin (Farxiga) did now not hinder renal outcomes for sufferers hospitalized with COVID-19, primarily based on a secondary prognosis of the DARE-19 trial.
Among sufferers with cardiometabolic threat factors, these taking dapagliflozin observed a identical prevalence for a composite kidney final consequence of acute kidney injure (AKI), kidney replacement therapy, or dying (HR 0.74, 95% CI 0.50-1.07), reported Hiddo Lambers Heerspink, PhD, PharmD, of the College of Groningen in The Netherlands, and colleagues.
This composite final consequence happened in 8% of the dapagliflozin sufferers and 10% of the placebo crew, the crew wrote in CJASN, Scientific Journal of the American Society of Nephrology.
The threat for this composite kidney final consequence did now not differ between baseline estimated glomerular filtration price (eGFR), both:
- <60 mL/min/1.73 m2: HR 0.91 (95% CI 0.49-1.69)
- ≥60 mL/min/1.73 m2: HR 0.65 (95% CI 0.40-1.05)
Taking a be taught about more closely at merely AKI — defined as a doubling of serum creatinine for the length of index hospitalization or investigator-reported serious adversarial tournament of AKI after discharge — these on dapagliflozin did now not gaze an elevated threat versus placebo. Regardless of baseline eGFR or treatment, the bulk of sufferers who developed AKI while hospitalized therefore died.
The antidiabetic agent used to be also neatly tolerated amongst hospitalized COVID sufferers, no subject baseline eGFR. Genuinely, fewer sufferers on dapagliflozin tended to experience serious adversarial events, at the side of AKI and these that led to dying, though this used to be a non-most primary distinction.
Diabetic ketoacidosis did now not happen in any sufferers with chronic kidney disease, but did happen in two sufferers with an eGFR ≥60 mL/min/1.73 m2.
“These fresh data from DARE-19 enhance the protection of dapagliflozin in acutely ill sufferers hospitalized with COVID-19 even in these with reduced kidney feature who’re at in particular excessive threat of acute kidney injure,” Heerspink talked about in an announcement.
Writing in an accompanying editorial, Katherine Tuttle, MD, of Windfall Scientific Research Heart in Spokane, Washington, talked about that DARE-19 used to be “a particular trial from the perspective of the protection of the expend of an SGLT2 inhibitor while experiencing acute illness in sufferers with both preserved or reduced kidney feature,” in particular close to AKI threat.
Nonetheless, she also identified that the definition of inpatient AKI used to be “stringent,” categorized as a doubling of serum creatinine the same to the Kidney Illness Improving Global Outcomes standards of stage 2. Ensuing from this, smaller and more acute drops in kidney feature would maintain likely been missed, potentially underpowering this prognosis, Tuttle talked about.
“Even if DARE-19 could presumably were underpowered to evaluate threat of AKI in hospitalized sufferers with COVID-19, the signal used to be in the true course and primarily based on the 25% lower threat of AKI considered in experiences of nonhospitalized individuals with diabetes, cardiovascular disease, or CKD [chronic kidney disease],” she wrote, at the side of that future experiences must still middle of attention on answering this lingering predict.
Namely for sufferers with CKD or heart failure, hospitalization is also “a golden 2d for implementation of an SGLT2 inhibitor in acceptable sufferers,” Tuttle suggested. “This could per chance be a key technique to enhance the dismally low implementation rates of SGLT2 inhibitors for kidney and heart protection in ethical sufferers.”
The trial itself could presumably were underpowered to evaluate AKI threat since the main outcomes had been geared toward assessing organ dysfunction and restoration.
As previously reported at the American College of Cardiology 2021 meeting, time to fresh or worsened organ dysfunction or dying from COVID-19 used to be non-most primary for dapagliflozin versus placebo (HR 0.80, 95% CI 0.58-1.10). Dapagliflozin also wasn’t vastly different from placebo when it got right here to COVID restoration (catch ratio 1.09, 95% CI 0.97-1.22) — defined as a substitute in medical space by day 30.
DARE-19 randomized 1,250 grownup sufferers who had been hospitalized with COVID-19 and had an oxygen saturation of ≥94% on supplemental oxygen. All sufferers also had a history of at the least one cardiometabolic threat ingredient equivalent to hypertension, form 2 diabetes, atherosclerotic cardiovascular disease, heart failure no subject ejection allotment, and/or CKD with an eGFR of 25-59 ml/min/1.73 m2.
At baseline, 18% of sufferers had an eGFR below 60 ml/min/1.73 m2.
Heerspink’s crew renowned an lickety-split low price of organ dysfunction and dying for the length of the trial, but added that “the subgroup analyses desires to be interpreted with warning, in express given the diminutive amount of events for the duration of the subgroups on the premise of baseline eGFR.”
