Stage 3 CKD is something that has to be taken seriously. In a previous post in this same blog, we talked about the 5 stages of Chronic Kidney Disease. We understood that stage 1 and stage 2 are not that serious and that the illness can be managed with diets and good habits. We also learned that Chronic Kidney disease in these two stages is invisible and that is very hard to detect unless other tests are done. We also learned that stage 3 is divided into two stages and that is here where the thing gets really serious (especially in stage 3B) and that it will be most likely that the patient needs treatment, medications, special diets and future dialysis and specific kidney treatments. Stage 4 and 5 are the last stages where the kidney is already working under 50% and the patient will need a transplant and a serious and well-managed treatment combined with diets and medications and we learned that stage 5 is already terminal and the patient has to be managed very carefully.

Today we are going to take a look at stage 3A within a Chronic Kidney Disease, the way it should be assessed and managed, the risk factors every patient has and some tips to prevent the progression of stage 3 in CKD.

Assessment and management of Stage 3 CKD

Most Stage 3 CKD patients are not at high risk and can be managed with primary care. The objective becomes to identify the patients that are in risk of passing on to stage 3B  and its associated risks.

The most important symptoms or pointers in stage 3A of patients at risk are: When the patient´s proteinuria is ACR>70 or PCR>100; the patient has a declining GFR and he or she is at a young age. After these pointers, doctors have to ask themselves if the patient is functioning well, if the patient has a history of this illness and if there has been any urinary abnormalities or other specific indicators.

The first value that has to be determined is the creatinine levels to see if they are elevated. Then compare them with previous tests and values. If previous tests don’t exist, there has to be a 14-day gap to take another test and compare values and it has to take them to the lab as deteriorating renal function needs rapid assessment.

As for the clinical assessment, the tests focus on heart failure or direct assessment of bladder enlargement. This can be done by imaging which can indicate the level of obstruction that doctor suspect. Here urine tests become ever more important because they can indicate the amount of proteinuria by ACR/PCR that can be seen in the body and this is a reliable indicator of progressive renal disease.

Management of Stage 3 CKD

In this stage, there is always a big cardiovascular risk. The idea is that the person starts having a healthier lifestyle and quit bad habits such as smoking, and starts a discipline in their exercise and eating habits. There should also be a cholesterol lowering therapy or approach if there are already any macrovascular disease symptoms. In this stage of CKD, the patients tend to be over 60 or 70 years old and most of them do not go onto stage 4. However, there should be a close assessment and control over diseases such as heart attacks, strokes, and narrowing of other arteries.

Stage 3 CKD risk factors

When we talk about risk factors we are mainly talking about cardiovascular events. The patient has to be monitored on his or her proteinuria, hematuria, and declining GFR levels and they must be closely managed. This is an accurate indicator that the CKD is progressing. The idea of understanding these risk factors is that doctors can accurately attack the kidney disease either by reducing the risk of having cardiovascular complications or by prescribing treatments that slow down or stop the progression of CKD.

Tips to prevent stage 3 CKD

Basically, there are three ways a person can prevent the body reaching stage 3 CKD: the first one is to have a kidney-friendly diet; the next one is to have a very good discipline when it comes to medications, and the third one is to exercise.

As for a kidney-friendly diet the idea is to eat the correct amount of calories, cut down on  phosphorus-rich foods because it is very hard for the kidney to process this type of food and avoid high-potassium foods (if  there is a possibility of a dietician it is a good idea because people can understand the amount of  potassium they can take.

Medications include drugs to prevent risk factors such as blood sugar levels and blood pressure.

Exercising and non-smoking become very important at this stage just to prevent the progression of CKD and to help the patient live his life as normal as possible.

The Most Significant Early Symptoms Of Kidney Disease

Kidney disease is the 9th leading cause of death in the United States of America. According to the American Kidney Fund, around 31 million Americans suffer from chronic kidney disease and men are more likely than women to have CKD. The leading causes of kidney failure are diabetes and high blood pressure, and that is why in some cases people fail to realize they have kidney problems until it’s too late. What seems to be a symptom of a different ailment ends up becoming the main health issue with many of these patients. One of the biggest problems with kidney disease is the psychological aspect that brings with it, as patients often feel like they are losing control over their life as their body doesn’t seem to respond to them, or acts in ways they aren’t familiar with.

The kidneys are responsible for keeping the human body’s chemistry in balance, a task that truly takes a toll on these amazing organs. As resilient as they are, the kidneys often suffer due to many different reasons and eventually become overwhelmed with all the stress they must perform under.

Today in Joe Cosgrove’s Blog, we want to take the time to look at some of the most significant early signs that can let you know that you may be developing kidney disease, with the hopes that you can do something about it before treatment becomes necessary.

Changes in urine

Since the kidneys are the organs in charge of producing the urine, this byproduct will be one of the first indicators that something may be amiss. Changes in urine can be identified as those in the appearance of color and the presence of foam, and also changes in the frequency in which the patient urinates or feels the urge to do so but is unable to produce any liquid. In some cases, there may be a pain while urinating or also the presence of blood.

Shortness of breath

Shortness of breath may be present in the onset of kidney disease because the fluid buildup in the body can be so severe that it can reach the lungs, something that will undoubtedly affect a patient’s breathing. Anemia or the lack of red blood cells in the organism can be another reason why patients may feel a lot of difficulty breathing.

Trouble sleeping

If kidneys stop working correctly, they amount of toxins that build up in the body will reach dangerous levels and will start affecting the organism in many ways. Patients report having trouble sleeping due to a constant feeling of discomfort that cannot be easily identified, they simply feel like they can’t sit still and have a lot of trouble resting.

Dry skin and constant itching are also symptoms of excess toxin build up in the body. Bone disease is also something else that may be present when kidneys fail, and constant itching is a clear symptom of that complication. Most of this happens because kidneys are losing the ability to properly balance nutrients, toxins, and minerals in the body.

Swollen joints

Swollen joints and general swelling are a sign that the body is holding excess water because they kidneys are not able to properly regulate bodily fluids, so they stay inside the body longer than they need to be. All of this is a side effect of sodium retention, something that happens because they kidneys are failing, and as sodium is kept in the body, so is water because it is retained by the sodium itself.

Puffiness around the eyes

If the kidneys aren’t working correctly, then things like protein will start to leak into the urine or other areas of the body. This together with excess fluids being retained is going to start showing in the face of the patient as swelling of the eyelids and cheeks.

Poor appetite

Patients with kidney disease will not feel the need to eat as much as healthy individuals. This is rather significant since these patients will still continue to gain weight even as they eat less everyday. The lack of appetite happens due to excess toxin build up in the body.

Muscle cramps

Electrolyte imbalance can start to manifest in the muscle by cramping and general soreness of the area. Low-level calcium and an imbalance in phosphorous levels make it, so they body is not properly using the fluids that it retains, and that can create painful muscle cramps.

Dizziness and problem thinking clearly

Another one of the symptoms has to do with mental acuity and the ability to think clearly. The brain may not be getting enough oxygen, and that is how it starts to show. Patients with kidney failure may begin to feel dizzy and have flash episodes in which they faint or lose balance. The ability to think clearly and solve simple problems starts to diminish as the body deteriorates.

A Brief History of Dialysis

Dialysis is a procedure commonly used to help filter the waste present in the blood when the kidneys simply can’t do it. As a medical procedure, it has been around for more than 70 years, helping patients have normal lives or at least livable ones.

Like most medical procedures, dialysis also has a story to be told, one that dates back to the 1940’s when the first dialysis machine was invented by a Dutch physician called Willem Kolff. Since the day this first machine was invented, to nowadays, dialysis has evolved incredibly, reaching the point where many patients are able to live with it for many years and still have regular lives.

In this article, Joe Cosgrove will share a bit of history related to dialysis and the great impact is has had in medical history and the lives of millions of people in time.

The 1940s: The beginning

At the beginning of the 1940’s a physician named Dr. Willem Kolff invented a device that worked as an artificial kidney. Thanks to his invention, Kolff is considered to be the pioneer of dialysis. As a physician, Kolff spent about 10 years of his career developing an artificial kidney in the Netherlands while working at the University of Groningen Hospital. He was first inspired to create this type of artifact when visiting the University Hospital and watching how a young man would irremediably die because his kidneys couldn’t filter waste anymore.

Once motivated to create something that could help those experiencing kidney failure, Kolff decided to go to research about ways to remove waste from the blood once the kidneys stopped working. Then he found an article written by the pharmacologist John Abel in 1913 about hemodialysis in animals. Thanks to this article, Kolff dedicated himself to the cause of developing an artificial kidney for humans.

Kolff had a hard time developing this device since he was sent to a remote hospital to serve at during war. Despite the poor conditions he kept on moving forward and improvised many times with many different materials (including sausage skins) to create something that could remove waste away from the blood.

By the year 1943 and after overcoming a great share of difficulties, Kolff’s invention was finished and was tested without any success on numerous patients, until in 1945, it helped an old woman overcome a uremic coma.

The machine Kolff invented is considered to be the first dialyzer of our times and its structure remained almost untouched for ten years as the best alternative for physicians to treat patients who were suffering from kidney failure. Probably Kolff didn’t know it back then, but his machine turned out to be one of the most important medical inventions in history and helped to save the lives of thousands.

The 1950s: Evolution of the dialyzer

At the beginning of the 1950’s, Kolff’s dialyzer had already been improved and used to treat injured soldiers fighting during the war. It had also been used to treat end-stage renal disease and acute renal failure patients. However, during the middle of the 20th century, not many doctors were optimistic about the usage of Kolff’s dialyzer because they believed a human made machine couldn’t resemble the kidneys’ function and they also found it difficult for the human veins to stand such treatment in the long term.

It was in Boston where a professor named Dr. Belding Scribner came up the idea of plugging the patient to the dialyzer by using flexible tubes made of a new plastic called Teflon. This way the tubes could be introduced inside the arteries and veins, keeping the circulatory access opened thanks to the usage of a tiny device with the shape of a “U”. This u-shaped device was called The Scribner Shunt.

By using this device patient no longer needed to get a new incision when going under the dialysis treatment. Even though this method isn’t used today, it helped other doctors develop new techniques to access the circulatory system that were useful to treat those who had acute kidney failure.

The 1960s: A decade of changes

Scribner was the first person on earth to open a dialysis facility in 1962. Problems started to appear when the number of patients who wanted and needed to be treated exceeded the capacity of the clinic – with only six available machines. Scribner needed to find a way to decide which patients were getting the dialysis done since many of them actually were close to death.

By this moment, Scribner decided to create an anonymous committee of people who could make that decision for him. This committee was composed of local people and doctors who worked in the kidney fields. Although this Solomonic choice created controversy, in time this committee was seen as the first bioethics committee of all time and changed the relationship common people had with the offer of health services.

The Past 60 Years

During the past 60 years, the history of dialysis has gone under several changes, new machines have been developed, new materials have been invented and many people in the world depend on this treatment to survive. We still know medical pioneers like Kolff or Scribner that are concerned about the way medicine evolves and is being practiced.

It is always expected in the future to come for specialists to be able to create new solutions that may help patients live longer, happier and have regular lives despite the fact they need to undergo dialysis treatment several times per week. History is still being written and hopefully, the years to come will be full of great surprises in this important medical field.
