Message from the Chief

Dear Division Members,

I am pleased to announce the launch of our new division newsletter, which will be a quarterly publication dedicated to sharing updates, insights, and news from our division with all members.

These are exciting times in Nephrology, with the advent of new diagnostic tools and novel therapies. As we continue to grow, it is important to stay connected and informed about how our division is contributing to these exciting developments within our field. The newsletter will serve as a platform to showcase the latest research and discoveries, new clinical programs, recent accomplishments of our members and provide resources and opportunities to enhance our professional growth and development.

We are committed to ensuring that the newsletter is engaging, informative, and reflective of the diverse interests and perspectives of our members. In future editions, we will have a spotlights dedicated to specific faculty members, fellows or administrators, and will get updates on graduates of our program.

Structures of LRP2 reveal a molecular machine for endocytosis

Structures of full-length native mouse LRP2 reveal that it is a homodimer that undergoes dramatic pH-dependent structural transitions that renders it ligand-receptive at the cell surface and ligand-shedding in endosomes. Beenken et al., 2023, Cell 186, 821–836

Clinical and Genetic Characteristics of CKD Patients with High-Risk APOL1 Genotypes

In this genetically matched cohort, high-risk APOL1 genotypes were associated with an increased risk of kidney failure and eGFR decline rate, with a graded risk between specific high-risk genotypes and a lower rate of monogenic kidney disease. Rare missense variants in the inflammasome pathway may act as genetic modifiers of APOL1 effect on kidney disease. Elliot et al., J Am Soc Nephrol. 2023 Feb 9.

Comprehensive Associations between Acidosis and the Skeleton in Patients with Kidney Disease

Metabolic acidosis is associated with multiple impairments in bone quality. Future work should examine whether correction of acidosis improves bone quality and strength in patients with CKD. Levy et al., J Am Soc Nehprology. April 2023

CRC Nephrology News

All of Us Research Program

AllofUs Research Program is an essential part of the Nephrology Division clinical research portfolio. The Program is a momentous effort to advance individualized prevention, treatment, and care for people of all backgrounds. People ages 18 and older, regardless of health status, can enroll. The overall aim is to enroll 1 million or more volunteers and oversample communities that have been underrepresented in research to make the program the largest, most diverse resource of its kind. Dr. Gharavi is the Principal Investigator for the NYC AllofUs Consortium (NYCC). Maria Morban, CRC, leads All of Us recruitment in the Division. Total enrollments in NYCC is 31, 402 (the goal is to enroll 93,000). 15, 651 participants are enrolled at Columbia, including 668 from Nephrology. In July, Maria enrolled 13 participants and was able to follow up on 9 previously enrolled.

Please, refer your patients to this study,. Feel free to email Maria at mm4345@cumc.columbia.edu if you have any questions.

IgAN Walk 6.11.23

On June 11th members of Dr. Kiryluk’s and Dr. Gharavi’s labs went to South New Jersey to participate in the IgAN annual walk. Special “thank you” goes to German Varela and Maayan Sofer, who prepared all the supplies. We recruited 21 people, including transplant patients and many family members. It was such a pleasure to reconnect with our former recruits and their family members. Sarath Krishna Murthy, the CPMG Director of Bioinformatics, took a part in the 5K run, and did very well! Nick Steers was in charge of answering science-related questions, and the participants kept him busy all the time!
Thank you to everyone who took a part in it: 

(German Varela, Estephany Disla, Maayan Sofer, Maria Morban, Vanna Nicasio, Sharvari Pathak, Jenna Simpson, Rachel Mufson, Nikita Toma, Kelsey Stevens, Nick Steers, Sarath Krishna Murth, Vita Kolupaeva)


eMERGE IV Update

eMERGE IV (Electronic Medical Records and Genomics Phase IV) Study (Dr. Krzysztof Kiryluk is one of the Principal Investigators) has now approached 50% target with nearly 1,200 participants enrolled; first genomic risk reports are now being returned to the participants and their physicians. It is an amazing milestone! Congratulations! German Varela and Estefhany Disla, CRCs, enroll patients not only in Nephrology, but all over the campus, even traveling to the Tarrytown clinic. The recruitment will continue over the next 12 months, so it’s not too late to participate or refer your patients for this exciting study!
