A Day in the Life of a Renal Pathologist

8:30-10:00am: I get to work and have some coffee. For most physicians, this time of day is devoted to research, reading & writing, teaching conferences or even dropping the kids off at school. As the Physician Chief at Arkana, my mornings are usually filled with meetings. My meetings typically are with members of the physician team who have areas of responsibility they oversee or with the content team where we create all the content you see on Arkana’s Twitter/Facebook and Blog. One day a week I try to devote this time to my research projects.  10:00-11:00am: I attend our daily case conference...

Twitter Poll (February 12th)

Answer: C Transplant glomerulopathy (TG) is characterized by duplication of glomerular basement membrane (GBM) and is graded based on the percentage of glomerular capillary loops with GBM duplication or double contours in the most affected non-sclerotic glomerulus by LM. TG often indicates the presence of chronic antibody mediated rejection, for which there will be glomerulitis (B), C4d positivity in PTCs (C), and mesangial matrix increase (A).  These findings are not in isolation from one another, therefore, "all of the above" would also be a correct answer. The Banff Lesion Score cg is based on the presence and extent of GBM double...

Twitter Poll (February 5, 2020)

ANSWER: D 2,8-dihydroxyadeninuria (DHA) disease is a rare autosomal recessive disorder caused by complete adenine phosphoribosyltransferase (APRT) deficiency and manifests as recurrent nephrolithiasis. 2,8-DHA can lead to irreversible renal failure and frequently recurs in the transplants. For the blog: Adenine phosphoribosyltransferase (APRT) deficiency is a rare autosomal recessive inherited disorder of purine metabolism. APRT catalyzes the formation of adenosine monophosphate from adenine. In the absence of APRT activity, adenine is catabolized by xanthine oxidase to 2,8-dihydroxyadenine (DHA), which is excreted in the urine. DHA is insoluble in the urine at the physiological range of pH, which may lead to crystalluria....
