Problem here is - especially in places like ours (India), affordability remains a problem - with the amount they spend on a biopsy they could afford 6 months of non immune therapy - so our biopsies are probably- At diagnosis and then only when absolutely indicated #NephJC

Fascinating finding: many patients lost chimerism but stayed IS-free. 🤔 This suggests chimerism is a transient 'switch' to turn on tolerance, not the long-term mechanism itself. We urgently need to identify that mechanism for safer weaning protocols. #NephJC

T0h A Chimera was an ancient beast with 🦁,🐐, and 🐍 parts. In modern times, genetic chimerism has been used to create immune tolerance. Infusion of donor hematopoietic stem cells & the presence of the cells in the recipient's blood stream, has been shown to induce functional tolerance. #NephJC

T0f Immune tolerance is defined as “a state of indifference or non-reactivity towards a substance that would normally be expected to excite an immunological response.” This is one potential strategy that would allow withdrawal of immunosuppressive medications. #NephJC

The guidelines point out literature that home BP seems prognostically similar to ABPM and better for repeatability/longitudinal monitoring. We still use ABPM a lot, but for situations where we need more detailed data (BP lability, new target organ damage, unclear if home BPs are accurate) #nephjc

Everything said and done - although eGFR diff may signal ominous outcomes - practically speaking following one eGFR over time and seeing the eGFR fall predicts outcomes better than anything else ! And that’s what would be feasible across economies ! #NephJC

T3c 🤔Does mGFR = eGFR? Nope 📉Imprecision: eGFR fluctuates when measured repeatedly 🔁 📊Systematic Bias: nonlinear relationship between the filtration marker & how GFR is mathematically represented (over-simplification) 🧮 Does this matter clinically since it is only an “estimate”? #NephJC

This is a really good point. Both eGFRs can be distant from mGFR, or one closer than the other. Isn’t correlation with mGFR more important than eGFRdiff? Maybe, but that’s not what this study was examining #NephJC

That’s impressive. So is eGFRdiff just another marker for “inflammation”? High=less inflamed, low/negative=more inflamed with worse outcomes. #NephJC

The results beg a huge question - the patients who belonged the negative quintile and had the worst outcomes - also had poorer mGFR (48ml/min mean) (Iothalamate) - (Vs 68 in the positive group) so what part of the poor outcomes were because of their low GFR per se? #NephJC
