Latest episode of @freelyfiltered.bsky.social is live! This one on the two RCTs of DDAVP to prevent renal biopsy bleeding. We had special guest Vandana Niyyar join us. @medpeedskidneys.bsky.social @captainchloride.bsky.social

Have a patient with DDAVP induced hyponatremia? I know every neuron in your brain says stop the DDAVP, but don't! Terrible outcomes from rapid correction of hyponatremia with that strategy.

We are discussing 2 studies on the use of desmopressin/ddAVP prophylactically to prevent post kidney biopsy bleeding.

5. Consider proactive DDAVP use

For patients at high risk of rapid overcorrection - the classic hypovolemic patient is a great example - I love a proactive DDAVP strategy (rather than reactive) 🤝

Beautifully explained in this classic @PulmCrit post: emcrit.org/pulmcrit/tak...
Taking control of severe hyponatremia with DDAVP
. Introduction with a case . Imagine an elderly patient presenting with hypovolemic hyponatremia (sodium of 115 mM) and moderate confusion.  How would you

No Disclosures - except I don’t think ddAVP does much

DDAVP 0.3-0.4 mcg/kg IV ↑ VWF & factor VIII release. VWF binds GPIIb-IIIa receptor on platelets, causing aggregation = antiplatelet reversal.

DDAVP ↑ platelet function in patients on antiplatelet like P2Y12i (PMIDs: 18068065,1434725,8330156)

Pulled up the IBCC from @pulmcrit.bsky.social for several things to show the team (hypertriG pancreatitis, DAH work up, DDAVP clamp, etc) and my residents are like what is this magic website 🤩

Is DDAVP any use before a kidney biopsy?

📍Different inclusion = different risk profiles.
Are we really comparing DDAVP performance—or just patient selection? Nice info @nephroseeker.medsky.social #NephJC

We dont hve injectible DDAVP available in India ..oral or nasal formulations only #NephJc

- TTKG
- 24 hour urine collections instead of ACR/PCR
(maybe we should move into that for stones also)
- calculating TBW and formulae for hyponatremia correction versus just giving 3% with ddAVP 🗜️

Limitations 🧩
⚠️ No p-value for interaction in subgroup
⚠️ DDAVP dosing differed
⚠️ Procedural variability (needle size, operators, passes) may confound bleeding outcomes
⚠️ Neither trial defined an “ideal” DDAVP candidate

Iron deficiency is difficult to treat without managing the primary issue. HMB can be treated with hormonal options (combined oral contraceptives or progesterone only options), or hemostatic agents (antifibrinolytics such as lysteda or amicar, DDAVP or factor products).

However, there is not consistent data to support this. Antifibrinolytics or DDAVP can be used to prevent excessive bleeding with insertion.

Expulsion is associated with high flow so controlling the first few periods (with the above) can be helpful to avoid this!

So… when should we use DDAVP? Who actually benefits?
So let’s find out with tonight´s two fresh RCTs.
Buckle up — before biopsy bleeding shows up

I really do love a nice 3% saline gtt and a DDAVP clamp. The closest you can get to “set it and forget it” with hyponatremia
March 30, 2024 at 1:32 PM
🤔 No mortality. No nephrectomies.
Transfusions and embolizations rare.
So do we need DDAVP to prevent rare events?
Do soft endpoints justify prophylaxis? #NephJC

💊 Different trials, different DDAVP strategies:
🔹Prasad et al: fixed 300 mcg intranasal dose
🔹Chakrabarti et al: weight-based 3 mcg/kg intranasal
🧬 Only Prasad tracked vWF & Factor VIII levels

So how does DDAVP skip the bleeding drama? 🩸
🧬 Desmopressin → triggers cAMP → exocytosis of vWF & FVIII from endothelium
➡️ Boosts platelet adhesion in uremic dysfunction
⏱️ Onset: 30–90 min ⏳ Duration: 4–8 h
