D’immunity

I can just see your faces now. Huh? What is that? The concept makes sense, but the word doesn’t. Do you remember my mentioning that one of the joys of being a writer is that you make up words? Well, that’s one I made up right after my doctor talked with me about vitamin D and immunity. He was talking about warding off a reoccurrence of cancer, but when I started researching I found that it has to do with all immunity.

Wait a minute. Just as I keep reminding you that I’m not a doctor and never claimed to be one, it’s important you realize that when I use the word ‘research,’ I mean searching the web and whatever journals or texts I have available. I am not a researcher in the true sense of the word. My favorite dictionary, The Merriam-Webster at https://www.merriam-webster.com/dictionary/research can help us out here:

1: careful or diligent search

2: studious inquiry or examination especially investigation or experimentation aimed at the discovery and interpretation of facts, revision of accepted theories or laws in the light of new facts, or practical application of such new or revised theories or laws

3: the collecting of information about a particular subject”

(‘Er’ is a suffix that means ‘one who,’ so a researcher is one who researches.) Most of us think of a researcher as the second definition. I think of myself as the third definition.

Okay, now that’s cleared up let’s get back to the miraculous vitamin D and your immunity. ScienceDaily at https://www.sciencedaily.com/releases/2019/04/190417111440.htm tells us,

“The University of Edinburgh team focused on how vitamin D affects a mechanism in the body’s immune system — dendritic cells’ ability to activate T cells.

In healthy people, T cells play a crucial role in helping to fight infections. In people with autoimmune diseases, however, they can start to attack the body’s own tissues.

By studying cells from mice and people, the researchers found vitamin D caused dendritic cells to produce more of a molecule called CD31 on their surface and that this hindered the activation of T cells.

The team observed how CD31 prevented the two cell types from making a stable contact — an essential part of the activation process — and the resulting immune reaction was far reduced.

Researchers say the findings shed light on how vitamin D deficiency may regulate the immune system and influence susceptibility to autoimmune diseases.

The study, published in Frontiers in Immunology, was funded by the Medical Research Council, Biotechnology and Biological Sciences Research Council, Natural Environment Research Council and Wellcome.”

If you’re like me, you’ll need help with some of these terms.

Dendritic cells are:

“a branching cell of the lymph nodes, blood, and spleen that functions as a network trapping foreign protein,”

according to Dictionary.com at https://www.dictionary.com/browse/dendritic-cell.

Let’s take a look at T cells now. I was comfortable with MedicineNet at https://www.medicinenet.com/script/main/art.asp?articlekey=11300’s definition:

“T cell: A type of white blood cell that is of key importance to the immune system and is at the core of adaptive immunity, the system that tailors the body’s immune response to specific pathogens. The T cells are like soldiers who search out and destroy the targeted invaders.

Immature T cells (termed T-stem cells) migrate to the thymus gland in the neck, where they mature and differentiate into various types of mature T cells and become active in the immune system in response to a hormone called thymosin and other factors. T-cells that are potentially activated against the body’s own tissues are normally killed or changed (“down-regulated”) during this maturational process.”

I’m sure my doctor had been telling me about this during the course of my treatment, but last week – now that I’ve been declared cancer free – immunity became a big issue to me and I finally listened with both ears. Maybe you should, too, since we’re in the middle of the Corona Virus Pandemic.

Let’s get some more information about vitamin D and your immunity. Healthline at https://www.healthline.com/nutrition/vitamin-d-coronavirus#effect-on-immune-health gives us another view of vitamin D and the immune system:

“Vitamin D is necessary for the proper functioning of your immune system, which is your body’s first line of defense against infection and disease.

This vitamin plays a critical role in promoting immune response. It has both anti-inflammatory and immunoregulatory properties and is crucial for the activation of immune system defenses ….

Vitamin D is known to enhance the function of immune cells, including T-cells and macrophages, that protect your body against pathogens….

In fact, the vitamin is so important for immune function that low levels of vitamin D have been associated with an increased susceptibility to infection, disease, and immune-related disorders ….

For example, low vitamin D levels are associated with an increased risk of respiratory diseases, including tuberculosis, asthma, and chronic obstructive pulmonary disease (COPD), as well as viral and bacterial respiratory infections….

What’s more, vitamin D deficiency has been linked to decreased lung function, which may affect your body’s ability to fight respiratory infections….”

I caught a word or two in that explanation that we may need defined.

Vocabulary.com at https://www.vocabulary.com/dictionary/pathogen informs us that a pathogen is,

“… is a tiny living organism, such as a bacterium or virus, that makes people sick. Washing your hands frequently helps you avoid the pathogens that can make you sick.”

How about macrophages? I went to News Medical Life Sciences at for their definition.

“Macrophages are important cells of the immune system that are formed in response to an infection or accumulating damaged or dead cells. Macrophages are large, specialized cells that recognize, engulf and destroy target cells. The term macrophage is formed by the combination of the Greek terms “makro” meaning big and “phagein” meaning eat.”

This must be what my doctor was talking about re cancer.

On another note: I am 73, still undergoing chemotherapy, and have Chronic Kidney Disease. Please be kind to me and others like me by wearing your mask, even if you hate it or think it makes you look weak. You could be saving my life.

Until next week,

Keep living your life!

Saving CKD Lives

Last week, I wrote about Covid-19 and a little about precautions explaining why we – as Chronic Kidney Disease patients – need to take extra care. A reader in Ireland was shocked that this was all we had in the way of protecting ourselves (as much as possible) from contacting the virus here in the United States. The precautions weren’t that much different than the precautions for everyone else.

There are a few things going on here. First is that we have no leadership from Mr. Trump who seems to have decided this is not his responsibility. That leaves us with the governors of each of the fifty United States and, in some cases, the mayors of individual cities in each of these states to lead us. They may have very different ideas.

There is this post I found on Facebook that exemplifies our situation in the U.S. Unfortunately, it is not attributed to anyone. I would love to give credit where credit is due.

“WE ARE NOT IN THE SAME BOAT …

I heard that we are all in the same boat, but it’s not like that. We are in the same storm, but not in the same boat. Your ship could be shipwrecked and mine might not be. Or vice versa.

For some, quarantine is optimal. A moment of reflection, of re-connection, easy in flip flops, with a cocktail or coffee. For others, this is a desperate financial & family crisis.

For some that live alone they’re facing endless loneliness. While for others it is peace, rest & time with their mother, father, sons & daughters.

With the $600 weekly increase in unemployment some are bringing in more money to their households than they were working. Others are working more hours for less money due to pay cuts or loss in sales.

Some families of 4 just received $3400 from the stimulus while other families of 4 saw $0.

Some were concerned about getting a certain candy for Easter while others were concerned if there would be enough bread, milk and eggs for the weekend.

Some want to go back to work because they don’t qualify for unemployment and are running out of money. Others want to kill those who break the quarantine.

Some are home spending 2-3 hours/day helping their child with online schooling while others are spending 2-3 hours/day to educate their children on top of a 10-12 hour workday.

Some have experienced the near death of the virus, some have already lost someone from it and some are not sure if their loved ones are going to make it. Others don’t believe this is a big deal.

Some have faith in God and expect miracles during this 2020. Others say the worst is yet to come.

So, friends, we are not in the same boat. We are going through a time when our perceptions and needs are completely different.

Each of us will emerge, in our own way, from this storm. It is very important to see beyond what is seen at first glance. Not just looking, actually seeing.

We are all on different ships during this storm experiencing a very different journey.”

Let’s take a look at the Chronic Kidney Disease boat to see what I can find out for us. I immediately went to the National Kidney Foundation at https://www.kidney.org/coronavirus/kidney-disease-covid-19. If you’ve read last week’s blog, then you already know we are more vulnerable to Covid-19 and why.

Are there special precautions that someone with kidney disease should take?

Older adults and people with kidney disease or other severe chronic medical conditions seem to be at higher risk for more serious COVID-19 illness. If you are at higher risk of getting very sick from COVID-19, you should:

  • Stock up on supplies
  • Take everyday precautions to keep space between yourself and others
  • When you go out in public, keep away from others who are sick, limit close contact
  • Wash your hands often
  • Avoid crowds as much as possible
  • During an outbreak in your area, stay home as much as possible.

Please remember that if you are on dialysis, you should not miss your treatments. Contact your clinic if you feel sick or have any questions or concerns.

If you have a kidney transplant, it is important to remember to keep taking your anti-rejection medicines, maintain good hygiene and follow the recommendations from your healthcare team. Contact your healthcare team with any questions or concerns….

Should CKD patients wear masks in public?

It is best to stay home, unless you need to attend a dialysis treatment. If you must go out in public, ask your healthcare provider if it is necessary as a CKD patient to wear a face mask since each individual case is different.

The Centers for Disease Control and Prevention (CDC) recommends face masks for those who are infected with COVID-19, have symptoms of COVID-19, or taking care of someone with COVID-19.

The CDC also recommends wearing cloth face coverings to slow the spread of COVID-19 in areas where community-based transmission is significant. These homemade cloth face coverings are not masks and do not replace the President’s Coronavirus Guidelines. (Gail here: As you can see, Trump doesn’t have much more to offer than what we already know. To be fair, this site hasn’t been updated since March 16th, over a month ago. Wait a minute! Why isn’t this site updated daily?)

Tips for using a mask include a snug but comfortable fit covering the bridge of the nose and the entire mouth. Also, be sure to be laundered [sic] the cloth mask after use each outdoor use, ideally without damage to the shape or structure of the mask. … The CDC also recommends coffee filters as an alternative. Use of any mask is in addition to practicing social distancing or at least 6 feet from others to limit coronavirus spread. All patients at high risk, such as immunosuppressed transplant recipients or people receiving dialysis should follow the directions of their clinicians regarding the type of face covering that should be used outside of a clinic setting.

When in public it is important to practice social distancing by staying 6 feet away from other people and to also avoid touching your face. Wash your hands immediately after you have been in public.”

This is still paltry information at best. Emedicine at https://www.emedicinehealth.com/script/main/art.asp?articlekey=228849 gives us just a bit more insight about patients on dialysis according to the CDC:

“The CDC (Centers for Disease Control and Prevention) guidance recommends that for medically stable patients facilities give the option of waiting in a personal vehicle or outside the facility and to be contacted by mobile phone when they are ready to be seen.

  • Dialysis facilities should have space allocated to allow patients who are ill to sit separately from other patients by at least 6 feet.
  • Patients experiencing respiratory symptoms should promptly be taken to appropriate treatment areas to reduce time in waiting areas.
  • For those with symptoms, ideally, dialysis treatment should be provided in a separate room from other patients, with the door closed.
  • If a separate room is not available, the masked patient should be treated at a corner or end-of-row station not near the main traffic flow. A separation of at least 6 feet should be maintained between masked, symptomatic patients and other patients during treatment.
  • Use of hepatitis B isolation rooms should only be considered for patients with respiratory symptoms if the patient has hepatitis B or if no patients treated at the facility have hepatitis B.

Healthcare personnel caring for patients with undiagnosed respiratory infections should further observe standard contact and droplet precautions with eye protection unless a suspected diagnosis such as tuberculosis requires airborne precautions, according to the guidance.

Precautions should include using gloves, facemasks, eye protection, and isolation gowns.”

And transplantees? I am so frustrated by the lack of more concrete information that might be more helpful than that given to non-kidney patients. UNOS (United Network for Organ Sharing) at https://optn.transplant.hrsa.gov/governance/policy-notices/ offers the following information:

COVID-19 Policy Actions Implemented

The table below contains information for actions taken to address OPTN operational issues in the COVID-19 crisis.

Policy Summary Documents & supporting resources Effective date
Policy 1.4.F: Updates to Candidate Data during 2020 COVID-19 Emergency This emergency policy will allow transplant programs to refresh candidate clinical data with data obtained through previous testing in order to maintain current waitlist priority.

This policy prevents candidates who cannot undergo routine testing due to the COVID-19 crisis from being adversely affected on the waitlist.

OPTN Policy Notice March 17, 2020
Policy 3.7.D: Applications for Modifications of Kidney Waiting Time during 2020 COVID-19 Emergency This emergency policy allows transplant programs to submit a waiting time modification application to retroactively initiate waiting time for affected candidates.

This policy prevents potential non-dialysis candidates who meet creatinine clearance or glomerular filtration rate (GFR) criteria from being disadvantaged because they cannot obtain other testing required.

OPTN Policy Notice April 3, 2020
Policy 18.1: Data Submission Requirements
Policy 18.2: Timely Collection of Data
Policy 18.5.A: Reporting Requirements after Living Kidney Donation
Policy 18.5.B: Reporting Requirements after Living Liver Donation
This emergency policy change relaxes requirements for follow-up form submission.

The intent of the policy is to prevent unnecessary exposure risk to transplant recipients and living donors, and also to alleviate data burden for centers in the midst of COVID-19 crisis.

 

Longer blog or not today – and it is much longer – I wish you all would adhere to these conditions. Are they restricting? Possibly. Are they uncomfortable? Could be. Are they lifesaving? It seems they are. Be safe.

Until next week,

Keep living your life!
