So Tired, Tired Of Waiting For…

It’s the year of the dragon!  Happy Chinese New Year to those who celebrate.  I have fond memories of the parades in NYC’s Chinatown and wending our way through firecracker wielding crowds to get to our favorite restaurant on something like 19 1/2 Pell Street. Or was it Mott Street?  Crooked streets, a below street level entrance and some of the best food I’ve ever eaten.  That was pre-CKD and I wonder if my taste buds have adapted to the renal diet enough that I wouldn’t appreciate the flavor any more if I ever get back there again.  Oh well, my kids can appreciate the food for me and I’ll appreciate the rest of the experience, my usual attitude toward something that might not be available to me these days.

I’m tired these days with “iron deficiency without anemia” but I clearly remember saying no to Epogen when it was suggested to me in the early days of my CKD.  It just struck me as wrong.  It was a gut feeling: I knew nothing about it at the time.  Since then, it’s been suspected of causing cancer and I’ve written about that in a previous blog.  I’ve also written in the book about how it’s necessary to remember that your kidneys are not functioning as they should which means that medication may stay in your body longer so you’d need less of it.  Has someone heard me?  Or was it just time for the medical community to implicate the cautions I’d been suggesting?

On the 19th of this month, ran the following:

New drug labels for kidney disease patients — what do they mean?

Drugs that treat anemia are critical for many who have kidney disease


  • More than 20 million adults in the United States have chronic kidney disease.
  • Drugs that treat red blood cell deficiencies are critical for maintaining many chronic kidney disease patients’ health.
  • Experts comment on newly released federal recommendations for these drugs.

Washington, DC (January 19, 2012) — The U.S. Food and Drug Administration (FDA) recently recommended that clinicians be more conservative when they prescribe chronic kidney disease (CKD) patients with drugs that treat red blood cell deficiencies. But the drug label’s recommendations fall short, according to two commentaries appearing in an upcoming issue of the Clinical Journal of the American Society Nephrology (CJASN).

The new federal recommendations apply to erythropoiesis-stimulating agents (ESAs). Patients with CKD may need these drugs if they lose the ability to make red blood cells and become anemic, which can make them tired, weak, and short of breath. ESAs treat certain types of anemia by stimulating red blood cell production and decreasing the need for blood transfusions. Drugs in the ESA class are epoetin alfa (marketed as Epogen and Procrit) and darbepoetin alfa (marketed as Aranesp).

Clinical trials have shown that ESAs can increase the risk of patients developing heart-related problems such as strokes and heart attacks when used to intentionally increase hemoglobin  (a red blood cell component) above 13 g/dL. Because of this, the new ESA label now states that clinicians should consider starting ESA treatment when a CKD patient’s hemoglobin is less than 10 g/dL, and they should individualize dosing and use the lowest dose of ESA to reduce patients’ need for blood transfusions. In addition, if a dialysis patient’s hemoglobin level approaches or exceeds 11 g/dL (10 g/dL for a CKD patient not on dialysis), clinicians should reduce or hold the dose of ESA. (The drug label previously recommended that ESAs be dosed to achieve and maintain hemoglobin levels within a target range of 10 to 12 g/dL in CKD patients. This target range concept has been removed from the label.)

A commentary by Braden Manns, MD (University of Calgary, in Alberta, Canada) and Marcello Tonelli, MD (University of Alberta, Canada) suggests that the new guidance is not completely consistent with the evidence and that some of the guidance may prove difficult for physicians to apply in practice. “The recent FDA labeling update seems balanced, although more specific guidance to clinicians would have been helpful,” the authors wrote. They suggest that instead of recommending that physicians individualize ESA dosing and reduce it when hemoglobin exceeds 11 g/dL in dialysis patients (10 g/L in non-dialysis CKD patients), perhaps the FDA should simply have recommended targeting hemoglobin ranges of 9 to 11 g/dL in dialysis patients and 9 to 10 g/dL in non-dialysis patients.

In a second commentary, Alan Kliger, MD, Fredric Finkelstein, MD (Hospital of St. Raphael and Yale University), and Steven Fishbane, MD (Hofstra North Shore-LIJ School of Medicine) take a different angle and propose that treatments for anemia should focus on the individual needs of each patient, weighing the risks and benefits in each case. While it is important to minimize patients’ chances of developing heart-related problems, it is also important for patients to feel less tired, have more energy and vitality, and be better able to function physically. “Instead of simply targeting hemoglobin levels, we should be looking at the hemoglobin level in the context of the patients’ perception of their quality of life and use ESAs judiciously to improve these perceptions,” the authors wrote. In other words, at what hemoglobin level do anemia-related symptoms become less burdensome for each individual patient? With this information in hand, physicians and patients will be better able to balance the risks versus the benefits of treatment.

You’ve got to weigh in with your own thoughts on this drug and it’s dosage.  Yes, your doctor is the specialist for your disease, but this is your life.  Take charge of it.

On the book front, possibilities are popping up, but I like to wait until they are certainties before announcing them, so:

Until next week,

Keep living your life!This is what Early Stage Chronic Kidney Disease looked like in August, 2011.  I could swear I had a picture from last week but just can’t find it.  Thank you to my dear friend and her daughter for inviting me to the wedding in Providence, Rhode Island.  (I’d expected to cool off a bit there, but ran right smack dab into a heat wave so it wasn’t just hot as it is here, but hot and humid.  The wedding made up for that!)
