A novel look at hyponatremia in the alcoholics

Tavare and Murray in a recent NEJM image had an interesting case of hyponatremia correction. The case highlights development of central pontine myelinolysis(CPM) despite slow correction of hyponatremia.  CPM is known to occur in alcoholism, liver disease and malnourishment in the absence of hyponatremia, hypokalemia or hypophosphatemia. 

We wanted to suggest an algorithm that can be used in settings where alcoholics present with moderate to severe hyponatremia with similar symptoms as presented in this case and are at risk of CPM.  The figure below is a novel algorithm that uses brain imaging to help us guide the therapy for moderate to severe hyponatremia in alcoholics.  



If the patient is symptomatic with seizures, the correction of hyponatremia should be promptly started.  If the patient is asymptomatic  or with milder symptoms and is encephalopathic ( with several  confounding  etiologies : hyponatremia, alcoholism, liver disease), a MRI of the brain should be performed. If the MRI confirms cerebral edema, hyponatremia should be treated with the usual slow rate of correction of 6-9mmol/L per 24 hours.  If the MRI confirms CPM, the correction of hyponatremia should be put on hold.  

We hypothesize that often the hyponatremia  in alcoholics is  chronic  and correction, regardless of the rate, might cause harm in these patients.

We welcome comments from experts on this concept.

Nephrologists as Super Heroes


When somebody asks me what nephrologists are, I usually respond with ‘superheroes.’ Sure, my perspective may be a bit skewed since I write for a comic series, and yes, superheroes may not be the first thing that pops into one’s mind when discussing the kidney. But in clinical practice, nephrology is a multidisciplinary field within medicine that requires deep knowledge of numerous organ systems. Acid-base disorders, dialysis, oncology, rheumatologic diseases, and transplantation are just some of the subjects in which a budding nephrologist gains expertise. Combine this prowess with the everyday challenges of providing primary care to chronic kidney disease patients, one can’t help but think of nephrologists as ‘superheroes’ in medicine.

When intensivists are struggling with an ABG, who do they call? The nephrologist. When cardiologists are struggling with hypertension and volume management, who do they call? The nephrologist. When endocrinologists are baffled by unexplained hypercalcemia, who do they call? You get the picture. Superheroes are wanted---and needed---in order to save the day.
You would think that young residents would be clamoring to don their capes and join the field of nephrology. But on the contrary, interest in nephrology has steadily been declining in recent years. According to Dr. Warren Kupin of U-Miami, the field of nephrology is suffering from an ‘acute fellowship insufficiency’, with fewer than 50% of programs filling their open fellowship positions, and some large academic programs going without even a single fellow. This lack of interest can be attributed to perceptions that this field is too complex, or perhaps to a lack of exposure to nephrology in residency. We may see ourselves as superheroes, but in actuality we are perceived more as “mutants” by the rest of the medical profession.

The mutants of X-Men are a group of individuals that were born with superhuman powers, but needed guidance, direction and purpose in order to flourish. They were constantly being targeted for their distinct abilities and talents that no humans could ever dream of possessing. The X-Men frequently had to fight for their mere survival. While on the pathway to annihilation, a bright light shined over these mutants. A gentleman by the name of Professor X would fill the void and provide mentorship to these troubled youth. He was a scholar and a role model for his students. It was through him alone that the X-Men were able to hone their powers for the good of mankind and recruit other mutants to Xavier’s Academy for Gifted Youngsters. Had it not been for the mentorship of Professor X, the mutants would have surely fallen into extinction.
Simply stated, we need more Professor Xs in nephrology. There needs to be a drive from within the field itself to demonstrate the attractiveness of our specialty. A systematic approach towards creating interest in our field must be undertaken to draw in the next generation of renal specialists. One way to make nephrology appealing to medical students and residents is through effective mentorship and education from the people within.
            When I was in medical school, I was assigned to a nephrologist as my attending physician for much of my internal medicine rotation. This was my first real exposure to what I would come to find as my life’s calling. I was intrigued by the complexities of renal physiology and its application in practice. I was excited by the life saving procedures of catheter placement and emergent hemodialysis in the emergency room and ICU. I was challenged by the detective work involved with diagnosing glomerular diseases. Now, in fellowship, my passion for the field has been furthered by being a part of the kidney transplant team.
            It is time we all do our part and take on the tradition of actively engaging and mentoring young physicians in the field of nephrology. Medical students and residents should be encouraged to rotate through nephrology electives with inspiring clinicians and passionate educators. By motivating a new trainee to consider a career in nephrology, you become more than a role model- you become a superhero. In the words of Professor X, “when you can access all that, you’ll possess a power no one can match. Not even me.”

Nephmadness 2016 Begins today

As each of you might be aware, NephMadness (now in its 4th year) is a way to promote our field to residents and medical students while each of us learn at the same time. NephMadness celebrates all things nephrology during the entire month of March (National Kidney Month). NephMadness (brought to you by the AJKD blog, the official blog of the American Journal of Kidney Diseases) is an online game that invites everyone to predict the "winners" of competing medical concepts.
Like in March Madness, where fans try to pick the winner of the NCAA Basketball Tournament, NephMadness provides brackets for participants to fill out online (click here for the submission site) and then compete with a worldwide community of peers. Winners of each “game” are determined by a majority vote of nephrologists we call the “blue ribbon panel”


  • Dan Weiner
  • Scott Gilbert
  • Nancy Adams
  • Jeffrey Berns
  • David S. Goldfarb
  • Melanie Hoenig
  • Roger Rodby
The medical concepts—or "teams"—are divided into eight regions highlighting different aspects of nephrology. They are:
  1. Hypertension Region: Raymond Townsend
  2. International Nephrology Region: Professor Vivekanand Jha
  3. Missteps in Nephrology Region: Mark Rosenberg, MD
  4. Transplant Nephrology Science Region: Milagros (Millie) Samaniego, MD
  5. Recreational Drugs and the Kidney Region: Mark A. Perazella, MD, FACP
  6. Pediatric Nephrology Region: John D. Mahan, MD
  7. Statistics in Nephrology Region: Perry Wilson, MD MSCE
Detailed scouting reports with background information is all provided at the blog. How do you pick the winner of each match. Simple, just select the medical concept that in his/her best medical judgment holds the most significant and promising benefit for the future of nephrology, weighting evidence-based medicine over eminence-based medicine.
NephMadness begins March 10th (World Kidney Day) and entries are collected until March 23rd when the game begins at roughly the same pace as the real NCAA tournament.
Winners of the concept matchups will be determined by a blue-ribbon panel of nephrologists and physicians. Those who guess the most correct matchups correctly will have a chance to win AJKD/NephMadness swag, textbooks, and fame!
Go to www.ajkdblog.org to review the scouting reports for each concept or go to the bracket submission site to place your votes.
