SGLT2 is responsible for reabsorbing up to 90% (animal data) of the glucose filtered at the glomerulus. The remaining 10% (animal data) is reabsorbed by SGLT1 that is expressed on the luminal (brush border) surface of cells of the S3 segment of the proximal tubule
Pathophysiology of Diabetic Nephropathy and role of SGLT2
Glomerular hyperfiltration over a long period of time is associated with podocyte stress and loss.
Over a period of time podocyte loss leads to glomerulosclerosis and atrophy
"We should be paying more attention to the proximal tubule" @ChristosArgyrop
A picture says a 1000 words-- the magic word is decreasing hyperfiltration
Why? maybe.. Increase glucagon levels– increase mg absorption in the distal tubule; Decrease in insulin levels – leading to movement of Mg to extracellular volume; Hemoconcentration related?; Reduced Mg excretion-effect on ion channel 6; insulin resistant effect on mg wasting
What else can they do? Improve Anemia in CKD
More EPO production as less effect of #hif
For the #onconephrology world- basic science study canagliflozin significantly attenuates cisplatin-induced nephropathy in C57BL/6 mice and suppresses cisplatin induced renal proximal tubular cell apoptosis in vitro. journals.physiology.org/doi/full/10.11…
Large analysis showing less kidney stones @weddellite@DMalieckal --- hmmm #flozinate for stone prevention..maybe the increase urine flow, decreased uric acid levels increased fluid intake by patients given being on SGLT2i link.springer.com/article/10.100… END PART 1
1.Tweet chain alert...on GNs with #covid19 vaccine... what is the most common GN seen post COVID19 vaccine?
2. A study led by Meryl Waldman @NIH creating a registry to evaluate de novo glomerular diseases potentially attributed to COVID19 vaccines published in @ASNKidney360@ASNKidney may help answer this question journals.lww.com/kidney360/Abst…
3. An earlier study by @Tiff_Caza showed IgA nephropathy, MCD, membranous nephropathy, crescentic GN, and collapsing GN as the most common GNs-attributed to COVID19 vaccines but was limited to 29 patients only pubmed.ncbi.nlm.nih.gov/35372991/@ASNKidney360
2. AA amyloidosis has been classically been associated with -- autoimmune diseases, chronic fevers, infections but AA amyloidosis can develop in a
localized or systemic form in patients with malignant neoplastic disorders
3. We performed a descriptive literature analysis and review of AA amyloidosis with cancer and its treatment.
76 case reports and 3 case/autopsy series with adequate information were included; 2 case reports were excluded due to lack of information on the subtype of amyloidosis.
2. Glomerular diseases are rare conditions that do require special expertise and expert centers to treat patients. The @NorthwellHealth GN center run by @purvasharma and @kdjhaveri along with expert pathologists @vbijol@Yihe28745445 will help train the next generations fellows
3) We just need an example of scholarly activity in the prior 3 years (any manuscript, abstract, presentation related to oncology/onconephrology). We have tried to keep the requirements to a minimum, in order to encourage trainees to join as well.
