What do you feel are the potential barriers to widespread use of obinutuzumab in proliferative lupus nephritis?
1. Insurance Coverage: Oh, easy one! Since it is not FDA-approved yet for lupus nephritis (I bet it will be though... great data so far), insurance will unlikely cover it, except for a few (like Tricare, which is sometimes easier to get off-label drugs). I am fortunate to have the NIH Lupus Center c...
Would you make any dialysis prescription modifications for an ESKD patient who develops tachycardia during a hemodialysis session?
Arrhythmias that initiate during dialysis treatment are almost always due to hypokalemia. Unfortunately, changing the potassium bath after an arrhythmia has already started will likely not help. The answer to the question depends on the circumstances of the patient. If unstable, would stop dialysis....
Do you postpone hemodialysis for a period of time after stem cell transplantation in a hospitalized patient with ESKD?
No. In fact, some patients may require extra HD sessions to manage volume overload post SCT. All ESKD patients are assessed daily for HD and continue to receive thrice-weekly dialysis per routine. If they are persistently hypotensive, they are considered for transition to CRRT.
Do you avoid potassium citrate in patients with recurrent nephrolithiasis and hypocitraturia if they also take antihistamine medications?
I know of no data showing effects of antihistamine meds on urine citrate or on the effects of potassium citrate on urine citrate. I made a Perplexity search which also found no evidence - this is not a topic I have personally researched because I have never encountered clinical issues about it. So -...
Is azilsartan superior to other angiotension receptor blockers in regard to cardiorenal outcome data?
In short, there are no data. There are very few head-to-head comparisons of ARBs on hard outcomes. Azilsartan was used in SPRINT (alongside losartan and valsartan), though the secondary analyses focused on class effect as opposed to specific med-to-med comparisons within a class (DeCarolis et al., P...
Do you routinely continue dual antibiotic coverage or de-escalate to monotherapy based on peritoneal fluid culture sensitivities in patients with relapsing pseudomonas aeruginosa peritoneal dialysis peritonitis after peritoneal catheter removal?
If the peritoneal dialysis catheter has been removed then I would de-escalate to monotherapy based on the fluid culture sensitivities. Monitor clinical response and obtain new fluid samples for analysis if any concern for persistent infection.
Would you perform a kidney biopsy to rule out other etiologies before diagnosing Loin Pain Hematuria Syndrome in a patient with persistent microscopic hematuria, left flank pain, no proteinuria, normal renal function, normal cystoscopy, and normal imaging?
Probably not unless something changes.
What are your top takeaways from ASN Kidney Week 2025?
Atacicept (ORIGIN Phase 3 Trial)Result: At 36 weeks, atacicept achieved a 46% reduction in proteinuria from baseline and 42% vs placebo (p<0.0001). Safety profile was favorable, with fewer serious adverse events than placebo. First large-scale evidence that dual BAFF/APRIL inhibition can modify dis...
What would be your approach to managing severe ANCA-associated vasculitis in a patient who is also septic from a bacterial infection?
It is prudent to evaluate if the ANCA-associated vasculitis is being triggered by the underlying bacterial infection. Certain clues on the kidney biopsy including diffuse exudative as well as diffuse crescentic [of same age] pattern of injury on light microscopy, intense C3 staining on immunofluores...
Is the accuracy of continuous glucose monitors (DEXCOM or Libre) lower in patients undergoing dialysis?
The question of the accuracy of CGM in dialysis patients is an important one and has been debated for some time. CGM is a superior method for glucose management over fingersticks in most clinical settings. Patients with ESRD on dialysis in particular, can have very difficult-to-control diabetes. A r...
