Platelets, Blood, and RSNHope or a Little Bit of This and a Little Bit of That

A reader from India asked me why I kept writing about chemotherapy. I explained that I have pancreatic cancer and that was part of my treatment. Chronic Kidney Disease patients may develop kidney cancer, although this type of cancer is not restricted to CKD patients. They also may develop another type of cancer that has nothing to do with the kidneys. Everyone’s experience with chemotherapy is different, but I thought one person’s experience was better than none. Here’s hoping you never have to deal with any kind of cancer or chemotherapy, however.

While we’re on explanations, I have a correction to make. The nurses at the Pancreatic Cancer Research Institute here in Arizona are a fount of knowledge. One of them heard me talking to my daughter about a platelet infusion and corrected me. It seems it’s a platelet transfusion, just as it’s a blood transfusion.

According to The Free Medical Dictionary at https://medical-dictionary.thefreedictionary.com/infusion

“in·fu·sion

(in-fyū’zhŭn),

  1. The process of steeping a substance in water, either cold or hot (below the boiling point), to extract its soluble principles.
  2. A medicinal preparation obtained by steeping the crude drug in water.
  3. The introduction of fluid other than blood, for example, saline solution, into a vein.”

The same dictionary, but at https://medical-dictionary.thefreedictionary.com/transfusion , tells us:

“Transfusion is the process of transferring whole blood or blood components from one person (donor) to another (recipient).”

Therein lays the difference. Platelets are part of the blood, so it’s a platelet transfusion. I’m glad that’s straightened out.

While we’re on this topic, here’s a chart of compatible blood types for transfusions… always a handy thing to have.

Blood Type of Recipient Preferred Blood Type of Donor If Preferred Blood Type Unavailable, Permissible Blood Type of Donor
A A O
B B O
AB AB A, B, O
O O No alternate types

O is the universal blood type and, as you’ve probably noticed, is compatible with all blood types. The plus or minus sign after your blood type refers to being RH negative or positive. For example, my blood type is B+. That means I have type B blood and am RH positive.

I’ve had platelet transfusions several times since I was leaking blood here and there. Nothing like eating lunch and having nasal blood drip into your salad. Ugh! You also become weak and your hemoglobin goes down. Not a good situation at all. You know I’m hoping you never need one, but who knows what can happen in the future. Just in case you’ve forgotten what platelets are, Macmillan Cancer Support at https://www.macmillan.org.uk/information-and-support/treating/supportive-and-other-treatments/supportive-therapies/platelet-transfusions.html#18772 is here to help us out.

“Platelets are tiny cells in your blood which form clots to help stop bleeding. They develop from stem cells in the bone marrow (the spongy material inside the bones). They are then released from your bone marrow into your blood and travel around your body in your bloodstream. Platelets usually survive for 7–10 days before being destroyed naturally in your body or being used to clot the blood.”

You’ll probably notice the term “RH Positive” (unless you’re RH Negative, of course) written on the platelet transfusion bag. You know I had to find out why.  Memorial Sloan Cancer Center at https://www.mskcc.org/cancer-care/patient-education/frequently-asked-questions-about-blood-transfusion offers this information about your blood that will help us understand:

“Your blood type is either A, B, AB, or O. It’s either Rh positive (+) or Rh negative (-).

Your blood type is checked with a test called a type and crossmatch. The results of this test are used to match your blood type with the blood in our blood bank. Your healthcare provider will check to make sure that the blood is the correct match for you before they give you the transfusion.”

The Mayo Clinic at https://www.mayoclinic.org/tests-procedures/rh-factor/about/pac-20394960 clarifies just what Rh Positive means:

“Rhesus (Rh) factor is an inherited protein found on the surface of red blood cells. If your blood has the protein, you’re Rh positive. If your blood lacks the protein, you’re Rh negative.

Rh positive is the most common blood type. Having an Rh negative blood type is not an illness and usually does not affect your health. However, it can affect your pregnancy. “

What I found especially interesting is that,

“If you have Rh-positive blood, you can get Rh-positive or Rh-negative blood. But if you have Rh-negative blood, you should only get Rh-negative blood. Rh-negative blood is used for emergencies when there’s no time to test a person’s Rh type.”

Thank you to Health Jade at https://healthjade.net/blood-transfusion/#Rh_Rhesus_factor for this information. This is a new site for me. You might want to take a look since their illustrations make so much clear.

Switching topics now. Are you aware of RSNHope.org? Lori Hartwell is one of the most active CKD and dialysis people I’ve met in the entire nine years I’ve been writing about CKD. For example, she has this wonderful salad bar help for the renal diet:

“Choose:  lettuce escarole, endive, alfalfa sprouts, celery sticks, cole slaw, cauliflower, cucumbers, green beans, green peas, green peppers, radishes, zucchini, better, eggs (chopped), tuna in spring water, parmesan cheese, Chinese noodles, gelatin salads, Italian low calorie dressing, vinaigrette, low fat dressing.

Avoid:  avocado, olives, raisins, tomatoes, pickles, bacon bits, chickpeas, kidney beans nuts, shredded cheddar cheese, three bean salads, sunflower seeds, Chow Mein noodles, fried bread croutons, potato salad, thick salad dressing, relishes”

What could be easier than printing this out and sticking it in your wallet? But Lori is not just about the renal diet. She also posts CKD & dialysis podcasts at KidneyTalk 24/7 Podcast Radio Show. All this and more are on the website. I must admit I look forward to the RSNHope magazine each quarter.

Say That Again

I have been uttering that phrase for years, maybe even a decade. Each time I went for a hearing test, I was told I was getting there, but I didn’t need hearing aids yet. This year it changed. I’ll bet it’s because I have CKD.

This is from SlowItDownCKD  2011:

“Research shows that hearing loss is common in people with moderate Chronic Kidney Disease. As published in the American Journal of Kidney Diseases and highlighted on the National Kidney Foundation web site, a team of Australian researchers found that older adults with moderate Chronic Kidney Disease (CKD) have a higher prevalence of hearing loss than those of the same age without CKD.”

How moderate CKD and hearing are connected is another matter, one that apparently isn’t as well documented. Here’s what I found on Timpanogos Hearing and Balance’s website at https://utahhearingaids.com/hearing-loss-likely-individuals-chronic-kidney-disease/ and the other sites I searched. This comes from the same Universtiy of Sydney study I cited in my 2011 blog.  A study that was completed in 2010… eight years ago.

“The link between hearing loss and CKD can be explained by structural and functional similarities between tissues in the inner ear and in the kidney. Additionally, toxins that accumulate in kidney failure can damage nerves, including those in the inner ear. Another reason for this connection is that kidney disease and hearing loss share common risk factors, including diabetes, high blood pressure and advanced age.”

Wait a minute. I wrote about this in SlowItDownCKD 2014, too:

“Suddenly it became clear. If toxins are – well – toxic to our bodies, that includes our ears. My old friend The Online Etymology Dictionary tells us the word toxic is derived directly from late Latin toxicus, which means ‘poisoned.’

Now I got it. Moderate CKD could be poisoning our bodies with a buildup of toxins. Our ears and the nerves in them are part of our body. Damaged nerves may cause hearing loss. I’d just never thought of it that way before. Sometimes all it takes is that one last piece of the puzzle to fall in place.

Hmmm. High blood pressure is the second most common leading cause of CKD and it can also lead to hearing loss. Let’s take a look at that.

According to WebMD

‘Certain illnesses, such as heart disease, high blood pressure, and diabetes, put ears at risk by interfering with the ears’ blood supply.’

I went right to What Is It and How Did I Get It? Early Stage Chronic Kidney Disease to figure out how since it includes a diagram from The National Institute of Diabetes and Digestive and Kidney Diseases, National Institutes of Health that demonstrates how high blood pressure is caused… and if you read on, you’ll read about the problems high blood pressure causes….and this sentence:

‘Humans have 10 pints of blood that are pumped by the heart through the arteries to all the other parts of the bodies.’

That would include the ears. Moderate CKD might mean that blood is tainted by the toxins our compromised kidneys could not rid us of.”

I was frustrated at not finding any more recent research, but sometimes you just have to take what you can get… like now.

I thought of an online hearing test I’d heard (Ouch! Poor word choice there.) about and decided to give it a try since it asked questions rather than having you listen to sounds as you would in an audiologist’s office. Here are my results from the  Better Hearing Institute at http://www.betterhearing.org/check-your-hearing

“SUMMARY

 Your hearing loss would be described as: Mild Hearing Loss. A hearing test may be necessary to monitor your hearing loss.

DETAIL REPORT

 Your Check Score: You scored 21 out of a possible 60 points. The remainder of this report will tell you what your score means.

Your Check Norm: Your score of 21 is at the 19 percentile of people with hearing loss in the United States, where low percentages mean lower hearing losses and high percentages mean more serious hearing losses compared to other people with hearing loss….

Subjective Hearing Loss Description: Based on the responses of more than 10,000 people with hearing loss and their family members, they would describe your hearing loss as: Mild Hearing Loss.

What Your Hearing Loss Means for Your Quality of Life: Research has shown that the higher your predicted hearing loss, the more likely the following quality-of-life factors may be negatively affected:

  • irritability, negativism and anger
  • fatigue, tension, stress and depression
  • avoidance or withdrawal from social situations
  • social rejection and loneliness
  • reduced alertness and increased risk of personal safety
  • impaired memory and ability to learn new tasks
  • reduced job performance and earning power
  • diminished psychological and overall health

What should you do next? Based on your score, we recommend the following: A hearing test may be necessary to monitor your hearing loss. Now hearing loss is situational, and the next step you take is dependent on your need to hear in various listening situations. Some people can live with mild hearing losses. Others, such as teachers and therapists whose auditory skills are very important for their everyday work, require corrective technology — such as hearing aids — even when their hearing loss is at mild levels. It becomes important for them to do something about their hearing loss so they can function adequately in their work environment….

Hearing Aids and Quality of Life

My audiologist will be introducing me to hearing aids in the new year. I thought I had considered all the ramifications of CKD. And, frankly, I thought I understood what was happening to my kidneys. It looks like I did understand the loss of some kidney function… just not how that would affect the rest of my body.

I don’t know whether to break out the duct tape or the crazy glue to keep this aging body in one piece. Are you laughing? Good, because I wanted to have this Chanukah blog leave you in a good mood. I know, I’ll break out the dreidles in your honor. Happy Chanukah!

Until next week,

Keep living your life!
