A New Year, New Kidney Disease Information

Happy New Year! Or, at least, that’s what I’m hoping for. I fervently believe the more you know, the better you can handle whatever’s happening in your world. That’s why, today, I’m exploring yet another term pertaining to kidney disease that I hadn’t been aware of. Oh my, how many, many types of kidney disease am I (and possibly you) unaware of?  

This one is membranous glomerulonephritis. I sort of-maybe-suspected what it might be, but I wanted to know for sure so I turned to Healthline – who bestowed a couple of awards on this blog a few years ago – at https://www.healthline.com/health/membranous-nephropathy for something more in the way of a definition. 

“Your kidneys are made up of a number of different structures that aid in the removal of wastes from your blood and the formation of urine. Glomerulonephritis (GN) is a condition in which changes in the structures of your kidney can cause swelling and inflammation. 

Membranous glomerulonephritis (MGN) is a specific type of GN. MGN develops when inflammation of your kidney structures causes problems with the functioning of your kidney. MGN is known by other names, including extramembranous glomerulonephritis, membranous nephropathy, and nephritis.” 

It’s hard to know where to start in exploring this disease. Let’s take the easy way and start with a definition of nephritis from… ta da, you guessed it – my all-time favorite dictionary, the Merriam Webster at https://www.merriam-webster.com/dictionary/nephritis.  

“acute or chronic inflammation of the kidney caused by infection, degenerative process, or vascular disease” 

I’m going back to the beginning of my blog journey to What Is It and How Did I Get It? Early Stage Chronic Kidney Disease for the following definitions. 

“Acute: Extremely painful, severe or serious, quick onset, of short duration; the opposite of chronic. 

 Chronic: Long term; the opposite of acute.” 

By the way, you can click on the title of the book if you’re interested in purchasing it from Amazon. 

So, basically, nephritis means a kidney problem. But membranous glomerulonephritis is something more specific in that it is a kind of GN or glomerulonephritis. Back to the dictionary for the definition of glomerulonephritis: 

“acute or chronic nephritis that involves inflammation of the capillaries of the renal glomeruli, has various causes (such as streptococcal infection, lupus, or vasculitis) or may be of unknown cause, and is marked especially by blood or protein in the urine and by edema, and if untreated may lead to kidney failure” 

Ah, so now we know what part of the kidneys are involved. Do you remember what the glomeruli are? Just in case you don’t, here’s how ‘s Lexicon at https://www.lexico.com/en/definition/glomerulus  defines this plural noun: 

“a cluster of nerve endings, spores, or small blood vessels, in particular a cluster of capillaries around the end of a kidney tubule, where waste products are filtered from the blood.” 

Now we’re getting somewhere. Let’s keep digging. Membranous glomerulonephritis is a specific GN. I went directly to MedlinePlus, which is part of the National Institutes of Health, which in turn is part of The U.S. National Library of Medicine at https://medlineplus.gov/ency/article/000472.htm

“Membranous nephropathy is caused by the thickening of a part of the glomerular basement membrane. The glomerular basement membrane is a part of the kidneys that helps filter waste and extra fluid from the blood. The exact reason for this thickening is not known. 

The thickened glomerular membrane does not work normally. As a result, large amounts of protein are lost in the urine. 

This condition is one of the most common causes of nephrotic syndrome. This is a group of symptoms that include protein in the urine, low blood protein level, high cholesterol levels, high triglyceride levels, and swelling. Membranous nephropathy may be a primary kidney disease, or it may be associated with other conditions. 

The following increase your risk for this condition: 

Cancers, especially lung and colon cancer 

Exposure to toxins, including gold and mercury 

Infections, including hepatitis B, malaria, syphilis, and endocarditis 

Medicines, including penicillamine, trimethadione, and skin-lightening creams 

Systemic lupus erythematosus, rheumatoid arthritis, Graves disease, and other autoimmune disorders 

The disorder occurs at any age, but is more common after age 40.” 

Being only a bit more than a year out from cancer, I was getting nervous so I went to the National Kidney Foundation at https://www.kidney.org/atoz/content/membranous-nephropathy-mn for a list of symptoms. 

“Swelling in body parts like your legs, ankles and around your eyes (called edema) 

Weight gain 

Fatigue 

Foaming of the urine caused by high protein levels in the urine (called proteinuria) 

High fat levels in the blood (high cholesterol) 

Low levels of protein in the blood” 

These symptoms struck me as so common that I wanted to know just how usual membranous glomerulonephritis was. After checking numerous sites, the consensus I found was that this is not a common disease. Thank goodness! 

Even though it’s not common, we still might want to know what to do if we were diagnosed with membranous glomerulonephritis, especially since I discovered that this may be considered an autoimmune disease. This is how the Mayo Clinic suggested the disease be treated: 

“Treatment of membranous nephropathy [Gail here: That’s a synonym for membranous glomerulonephritis.] focuses on addressing the cause of your disease and relieving your symptoms. There is no certain cure. 

However, up to three out of 10 people with membranous nephropathy have their symptoms completely disappear (remission) after five years without any treatment. About 25 to 40 percent have a partial remission. 

In cases where membranous nephropathy is caused by a medication or another disease — such as cancer — stopping the medication or controlling the other disease usually improves the condition.” 

There is much more detailed treatment information on their website at mayoclinic.in/354QFPU.    

That is a bit more reassuring. Thank you to all the readers who use terms I hadn’t heard of before and/or ask questions about topics that are new to me. May this year be kinder to us than the last one. 

Until next week, 

Keep living your life! 

Learning Every Day

 Chronic Kidney Disease is all over my world. You know when you have your ears open for a certain term, you seem to hear it all the time? That’s what my life has been like for the last dozen years. When I noticed a comment in a Facebook kidney disease support group about Action myoclonus–renal failure (AMRF) syndrome, I was stunned. Here was yet another possible kidney disease I’d never heard of. 

As defined by MedlinePlus, a division of the National Health Institutes (which is a division of the U.S. National Library of Medicine) at http://bit.ly/2KY6EI8,  

“Action myoclonus–renal failure (AMRF) syndrome causes episodes of involuntary muscle jerking or twitching (myoclonus) and, often, kidney (renal) disease. Although the condition name refers to kidney disease, not everyone with the condition has problems with kidney function.” 

I was intrigued and wanted to know more. So, I did what I usually do when that happens. I poked around everywhere I could think of on the internet. My first hit was on The National Center for Biotechnology Information (NCBI), which is part of The U.S. National Library of Medicine at https://www.ncbi.nlm.nih.gov/books/NBK333437/

“Action myoclonus – renal failure (AMRF) syndrome typically comprises a continuum of two major (and ultimately fatal) manifestations: progressive myoclonic epilepsy (PME) and renal failure; however, in some instances, the kidneys are not involved. Neurologic manifestations can appear before, simultaneously, or after the renal manifestations. Disease manifestations are usually evident in the late teens or early twenties. In the rare instances in which renal manifestations precede neurologic findings, onset is usually in late childhood / early adolescence but can range to the fifth or sixth decade.” 

Uh-oh, epilepsy. One of my children has that. Luckily for her, she doesn’t have CKD. But we still need more information… or, at least, I do. For instance, how does the illness progress? 

Rare Disease InfoHub at http://bit.ly/37Qgo0h answered this particular question. 

“The movement problems associated with AMRF syndrome typically begin with involuntary rhythmic shaking (tremor) in the fingers and hands that occurs at rest and is most noticeable when trying to make small movements, such as writing. Over time, tremors can affect other parts of the body, such as the head, torso, legs, and tongue. Eventually, the tremors worsen to become myoclonic jerks, which can be triggered by voluntary movements or the intention to move (action myoclonus). These myoclonic jerks typically occur in the torso; upper and lower limbs; and face, particularly the muscles around the mouth and the eyelids. Anxiety, excitement, stress, or extreme tiredness (fatigue) can worsen the myoclonus. Some affected individuals develop seizures, a loss of sensation and weakness in the limbs (peripheral neuropathy), or hearing loss caused by abnormalities in the inner ear (sensorineural hearing loss). Severe seizures or myoclonus can be life-threatening.” 

But we haven’t looked at the kidneys yet. How are they involved in those who develop kidney problems from this rare disease? Let’s go back to MedlinePlus to see what we can find. Don’t be surprised that the answer is fairly general: 

“When kidney problems occur, an early sign is excess protein in the urine (proteinuria). Kidney function worsens over time, until the kidneys are no longer able to filter fluids and waste products from the body effectively (end-stage renal disease).” 

Do you remember what proteinuria is? Here’s a reminder from my first CKD book – What Is It and How Did I Get It? Early Stage Chronic Kidney Disease – in case you’ve forgotten: 

“Protein in the urine, not a normal state of being” 

Hmmm, proteinuria is exactly what it sounds like. That got me to thinking: How does the protein get into the urine in the first place? 

“Protein gets into the urine if the kidneys aren’t working properly. Normally, glomeruli, which are tiny loops of capillaries (blood vessels) in the kidneys, filter waste products and excess water from the blood. 

Glomeruli pass these substances, but not larger proteins and blood cells, into the urine. If smaller proteins sneak through the glomeruli, tubules (long, thin, hollow tubes in the kidneys) recapture those proteins and keep them in the body. 

However, if the glomeruli or tubules are damaged, if there is a problem with the reabsorption process of the proteins, or if there is an excessive protein load, the proteins will flow into the urine.” 

Thank you to a trusted site, The Cleveland Clinic at http://cle.clinic/3nTjLZI for helping us out here.

The important point here is that proteinuria, or albumin as it is often called, prevents the substances that belong in your blood stream from fully remaining there to help you: 

“Blood contains two main kinds of proteins: albumin and globulins. Blood proteins help your body produce substances it needs to function. These substances include hormones, enzymes and antibodies. 

Usually, the amount of total protein in your blood is relatively stable.” 

I’d gone back to the reliable Cleveland Clinic for this information. 

I don’t know about you as you read today’s blog, but I found writing it exhausting. Of course, that may be due to the fact that Christmas Eve and Christmas Day have just passed. I’m not quite as vigilant as I usually am about the renal diet during certain celebrations. Considering that Bear’s Lutheran and I’m Jewish, that was a lot of celebrating. I see my exhaustion as an endorsement to get right back on the kidney diet. 

Here’s hoping your Chanukah, Christmas, Boxing Day, and Kwanza were as happy as you’d hoped under the restrictions of small group gatherings, six foot distancing, and mask wearing. We stayed home alone using the phone and Facetime to be with family.  

It was… different. But more importantly, it was safe. Keep in mind that you’re already immuno-compromised simply by having CKD. If you no longer have a spleen like me (Thanks, pancreatic cancer.), you’re even more immunocompromised. Hugs are the best, but they could be deadly for us. Stay safe. 

Until next week, 

Keep living your life!
