Researcher focused on immune deficiency in CKD.

Kidneys: the only organs that can throw shade. If they’re salty, you’re in trouble! 😉
Id like to hear your point of view.

Would you have gone for plasma exchange despite normal haptoglobin/bilirubin and a positive Coombs test?

💡 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

ein typischer Tag im Labor: Forschung und Präzision. 🧪🔬 Nephrologie bedeutet nicht nur Patientenkontakt, sondern auch intensive Arbeit im Labor, um die Nieren besser zu verstehen. #Medizin #Nephrologie #Forschung

Is it too on the nose to bring my colleagues these Christmas cookies shaped like kidneys? Or should I just embrace the nephro-cheesiness? 🎄🍪 #NephrologyLife

Is 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 !

Rituximab 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?

When 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?

This multicenter observational study recommends a sodium correction of at least 10 mmol/L in patients with severe hyponatremia who have no risk factors. I would be interested to hear Dr. Joel Topf’s @kidneyboy.bsky.social opinion on the matter.

Severe Hyponatremia Correction, Mortality, and Central Pontine Myelinolysis
In clinical practice, sodium correction rates are frequently limited in patients with severe hyponatremia to prevent neurologic complications. The implications of correction rates on overall mortal...
