Turning to kidney function — the most consistent physiologic effect.
Using iohexol clearance, dapagliflozin caused an acute dip in measured GFR.
The placebo-adjusted mGFR decline was:
– 4.2 ml/min/1.73 m² at 1 week
– 3.5 ml/min/1.73 m² at 12 weeks

Creatinine-based eGFR showed directionally similar changes, closely mirroring the early hemodynamic dip seen in native-kidney SGLT2i trials.
Crucially, this GFR dip was not accompanied by harm:
❌ No excess AKI
❌ No biochemical instability
❌ No signal for acute rejection

Participants were stable kidney transplant recipients, ≥6 months post-transplant.
Initially restricted to patients with diabetes, eligibility was later expanded to non-diabetic recipients after publication of DAPA-CKD. #NephJC

The dominant drivers of late graft failure and death are:
❤️ Cardiovascular disease (Death with a functioning graft) ⛔ Progressive graft failure from immune and non-immune injury. #NephJC

So here comes the quintessential, key unanswered question:
👉 Do SGLT2 inhibitors exert similar, altered, or entirely different physiologic effects in kidney transplant recipients—and more importantly are they safe? 📉 📈

The INFINITI trial has set out to answer this very question.
Let’s see if #Flozins can go to INFINITY AND BEYOND! (Disclaimer: Disney has not specifically endorsed #flozin use) #NephJC

🔍Proposed mechanisms of action of the #flozins include
-restoration of tubuloglomerular feedback
-intraglomerular pressure reduction
-osmotic diuresis
-improved tubular energetics.
Do these mechanisms also work in transplanted kidneys?

However, kidney transplant recipients have been excluded from all major SGLT2i outcome trials—creating a major evidence gap. For better (overly cautious) or worse, we have limited safety and efficacy data for renal transplant patients. #NephJC

Transplanted kidneys are physiologically distinct from native kidneys.
Denervated, exposed to calcineurin inhibitors, and characterized by altered sodium handling and vascular tone are just a few of the significant differences.
Can you think of others?

Welcome to #NephJC !
Let’s start with the big picture.
Transplantation remains the best RRT for survival and quality of life. Yet long-term graft survival has plateaued, with ~50% graft loss by 10 years.

concerns about flozinating in kidney transplant include:

- non hyperfiltration mechanism of injury (eg immunological + calcineurin induced)
- risk of infections - especially given short urinary tract + immunosuppression

we really need good data &. o extrapolation - let’s discuss tonight #NephJC

⏰30 min before the #NephJC chat

There has been limited research on SGLT2i in renal transplant recipients till date, and this is the compilation of currently available data. #NephJC

Are you pumped to know how and how well #Flozins work in transplanted patients?
Let's deep dive in a few minutes!

Yes. That is a bog standard vaccine trial! And 43,000 people basically leaves zero doubt about efficacy AND safety.

Oral semaglutide for weight loss was just approved with 205 patients! I get that it's had many many other trials as an injection but that's some hypocritical bullshit from the FDA

You know that coffee & dementia study that's going around?

It's hogwash.

For starters, it's not pre-registered (that I could find), which means it may have been the product of a fishing expedition looking for dementia associations.

But even if it's not ...

First blush reading all that... absolute anti vax nonsense. Perfectly acceptable for multiple other countries.

This will have yet another chilling effect on drug development pipelines.

Look at the data! It's all over the map.

If you drink half a cup per day, your risk is a little higher than none at all.

If it's 2.5 cups, risk is 20% lower.

But if it's 4.5 cups, risk is only 13% lower.

There's no universe where this makes causal sense.

Why are we still doing this? Why are we mining these noisy, inaccurate, confounded databases for associations so we can mislead people about what they ought to be eating?

I'd sure love to see @gidmk.bsky.social and @pwgtennant.bsky.social weigh in on this one.
