Humberto Luna @renalguy.bsky.social · 08/06/2026How do you dialyze chronic HD patients at high bleeding risk? Recent surgery, upcoming surgery, active bleeding, etc At our center: short heparin-free HD when feasible, or citrate CVVHD in ICU for selected cases Do you use saline flushes, citrate IHD, heparin-coated filters, or something else? 000
Humberto Luna @renalguy.bsky.social · 03/06/2026Question for nephrologists: Who places tunneled dialysis catheters at your institution? * Nephrology * Interventional radiology * Vascular surgery At my center, nephrologists are not involved. Curious how common this is. 622
Humberto Luna @renalguy.bsky.social · 31/05/2026Preliminary IMMUPROT data from Uniklinik Halle T-cell responses appear similar in CKD patients with severe albuminuria and those with „just“ reduced eGFR. Kidney dysfunction may be more relevant for T-cell immunity than albuminuria. Further analyses are ongoing. #Nephrology #CKD 000

Reposted by Humberto LunaJAMA Network Open @jamanetworkopen.com · 19/02/2026In #ChronicKidneyDisease, higher urinary protein to creatinine ratio was more strongly associated with increased risk of cognitive impairment than lower eGFR, suggesting the importance of proteinuria in cognitive risk assessment. ja.ma/3OvDzof 054
Humberto Luna @renalguy.bsky.social · 24/07/2025Id like to hear your point of view. Would you have gone for plasma exchange despite normal haptoglobin/bilirubin and a positive Coombs test? 010
Humberto Luna @renalguy.bsky.social · 09/12/2024💡 Chronische Nierenerkrankung schwächt das Immunsystem 🛡️ – Proteinurie 🧪 könnte eine Schlüsselrolle spielen. In meiner Doktorarbeit erforsche ich, wie Proteinurie und Immunfunktion zusammenhängen, um neue Ansätze 🩺 zur Risikominimierung und Behandlung zu entwickeln 010

Humberto Luna @renalguy.bsky.social · 29/11/2024Is it too on the nose to bring my colleagues these Christmas cookies shaped like kidneys? Or should I just embrace the nephro-cheesiness? 🎄🍪 #NephrologyLife 000
Humberto Luna @renalguy.bsky.social · 26/11/2024Is copeptin the missing link in diagnosing SIADH, or is it an overhyped biomarker with limited use? How often do you use it for managing hyponatremia? Would love to hear the thoughts of @kidneyboy.bsky.social and @captainchloride.bsky.social ! 100
Humberto Luna @renalguy.bsky.social · 25/11/2024Rituximab in GPA/MPA: 375 mg/m² weekly x4 vs. 1g twice, 2 weeks apart. Is BSA dosing truly better, or does fixed dosing offer equal outcomes with more simplicity? What does your practice prefer? 010
Humberto Luna @renalguy.bsky.social · 24/11/2024When diuretics fail, the albumin-furosemide combo is often considered—but is it science or just tradition? Evidence for its routine use is shaky at best. Are we truly helping our patients or just inflating costs and risks? 161
Humberto Luna @renalguy.bsky.social · 16/11/2024This multicenter observational study recommends a sodium correction of at least 10 mmol/L in patients with severe hyponatremia who have no risk factors.
