How Can I Live Well With Kidney Failure

How do your kidneys work? – Emma Bryce

Doing well with kidney failure is a challenge. You will feel better if you

  • stick to your treatment schedule
  • review your medicines with your health care provider at every visit and take your medicines as prescribed
  • work with a dietitian to develop an eating plan that includes foods you enjoy eating while also helping your health
  • stay activetake a walk or do some other physical activity that you enjoy
  • stay in touch with your friends and family

Treatment with dialysis or transplant will help you feel better and live longer. Your health care team will work with you to create a treatment plan to address any health problems you have. Your treatment will include steps you can take to maintain your quality of life and activity level.

Your eating plan plays an important role. When you have kidney failure, what you eat and drink may help you maintain a healthy balance of salts, minerals, and fluids in your body.

What Are Dialysis And Hemodialysis

Dialysis cleanses the body of waste products by body by use of filter systems. There are two types of dialysis, 1) hemodialysis and 2) peritoneal dialysis.

Hemodialysis uses a machine filter called a dialyzer or artificial kidney to remove excess water and salt, to balance the other electrolytes in the body, and to remove waste products of metabolism. Blood is removed from the body and flows through tubing into the machine, where it passes next to a filter membrane. A specialized chemical solution flows on the other side of the membrane. The dialysate is formulated to draw impurities from the blood through the filter membrane. Blood and dialysate are never touched in the artificial kidney machine.

For this type of dialysis, access to the blood vessels needs to be surgically created so that large amounts of blood can flow into the machine and back to the body. Surgeons can build a fistula, a connection between a large artery and vein in the body, usually in the arm, that allows a large amount of blood to flow into the vein. This makes the vein swell or dilate, and its walls become thicker so that it can tolerate repeated needle sticks to attach tubing from the body to the machine. Since it takes many weeks or months for a fistula to mature enough to be used, significant planning is required if hemodialysis is to be considered as an option.

Kidney Failure Definition And Facts

  • Kidneys are the organs that filter waste products from the blood. They are also involved in regulating blood pressure, electrolyte balance, and red blood cell production in the body.
  • Symptoms of kidney failure are due to the build-up of waste products and excess fluid in the body that may cause weakness, shortness of breath, lethargy, swelling, and confusion. Inability to remove potassium from the bloodstream may lead to abnormal heart rhythms and sudden death. Initially, kidney failure may cause no symptoms.
  • There are numerous causes of kidney failure, and treatment of the underlying disease may be the first step in correcting the kidney abnormality.
  • Some causes of kidney failure are treatable and the kidney function may return to normal. Unfortunately, kidney failure may be progressive in other situations and may be irreversible.
  • The diagnosis of kidney failure usually is made by blood tests measuring BUN, creatinine, and glomerular filtration rate .
  • Treatment of the underlying cause of kidney failure may return kidney function to normal. Lifelong efforts to control blood pressure and diabetes may be the best way to prevent chronic kidney disease and its progression to kidney failure. As we age, kidney function gradually decreases over time.
  • If the kidneys fail completely, the only treatment options available may be dialysis or transplant.

The Facts About Chronic Kidney Disease

  • 37 million American adults have CKD and millions of others are at increased risk.
  • Early detection can help prevent the progression of kidney disease to kidney failure.
  • Heart disease is the major cause of death for all people with CKD.
  • Glomerular filtration rate is the best estimate of kidney function.
  • Hypertension causes CKD and CKD causes hypertension.
  • Persistent proteinuria means CKD is present.
  • High risk groups include those with diabetes, hypertension and family history of kidney failure.
  • African Americans, Hispanics, Pacific Islanders, American Indians and Seniors are at increased risk.
  • Two simple tests can detect CKD: blood pressure, urine albumin and serum creatinine.

Uremic Compounds Involved In The Acute

The group of uremic compounds involved in the acute-phase processes includes those which can be associated with a generalized increase in the inflammatory response in patients with decreased renal function. Impaired renal function may enhance the overall inflammatory response because of the decreased renal clearance of compounds with antioxidant, anti-inflammatory and vasodilating properties, which in health can be filtered by the glomeruli , such as proinflammatory cytokines, 1-acid glycoprotein, neopterin and calcitonin. There is increasing evidence confirming the role of impaired intestinal barrier function and potential toxins either produced in the intestine or introduced with the ingested food via the intestine . Declining renal function may also affect the level of several acute-phase proteins with large molecules which are directly or indirectly involved in inflammation.

In patients with CKD, inflammation may be closely related to accelerated atherogenesis, protein-energy malnutrition and anemia via different mechanisms. Inflammation plays a key role in mediating CKD progression in response to infectious and noninfectious kidney damage. Increased levels of inflammatory markers predict poor outcome in patients with ESRD and chronic renal failure .

Ordering Takeout With Confidence

Many restaurants are now closed to enforce social distancing, but take-out is still available from many eateries. Here are some ideas for making ordering take-out easy even with your special kidney diet. Start by knowing your diet well and asking your dietitian for any tips or advice. If you have sodium, potassium, phosphorus, or protein restrictions, this information will help you make good decisions based on your specific dietary needs.

Plan ahead

Choose a restaurant where it will be easiest to select foods best suited for your diet. Restaurants where food is made to order are the best choice.

Making your selections

Look over the menu carefully. Ask for more details about items you do not know about. When you place your order explain that you are following a special diet. Make special requests about the way your food is prepared as follows:

Side dishes:

  • If you need to restrict potassium, choose starches and vegetables that are lower in potassium, such as rice, noodles and green beans.
  • If your meal does not include a good choice for your diet, request a substitute.
  • Ask that sauces be omitted or served in a separate container.

Acquired Diseases Affecting Both The Kidney And The Nervous System

Vasculitides, paraproteinaemias, and granulomatous conditions, by their nature, involve more than one organ system and several present with both renal and neurological syndromes. The syndromes are dealt with in other papers in the current series ofNeurology and Medicine, and are therefore only summarised in table .

What Is Kidney Disease

Kidney Disease and Dialysis | Health | Biology | FuseSchool

Kidney disease can affect your bodyâs ability to clean your blood, filter extra water out of your blood, and help control your blood pressure. It can also affect red blood cell production and vitamin D metabolism needed for bone health.

Youâre born with two kidneys. Theyâre on either side of your spine, just above your waist.

When your kidneys are damaged, waste products and fluid can build up in your body. That can cause swelling in your ankles, nausea, weakness, poor sleep, and shortness of breath. Without treatment, the damage can get worse and your kidneys may eventually stop working. Thatâs serious, and it can be life-threatening.

Classification Of Uremic Compounds

Based on 85 studies published in the years 1968-2002 and evaluating over 500,000 patients, the European Uremic Toxin Work Group listed substances with presumed or proven biological activity, the accumulation of which in the body resulted from end-stage renal failure. Newly identified substances are added to the list on an ongoing basis providing an increasingly complex picture of their potential toxicity .

Uremic retention solutes present a great variety of properties which makes their accurate classification extremely difficult. They make up a group with numerous members that differ in their water solubility, protein-binding capacity, molecular weight, pattern of removal by dialysis, biological properties and potential to produce clinical symptoms. In published studies, molar concentrations of uremic retention solutes ranged from a few picomoles per liter to micromoles per liter . The highest mass concentration was detected for acute-phase macromolecule 1-acid glycoprotein . The most common classification of uremic compounds into 3 groups proposed by EUTox is by molecular weight, protein-binding capacity and removal pattern by dialysis .

The Effect Of Kidney Failure On The Brain And Nervous System

Kidney Failure From Drinking Alcohol

Uremia

DialysisWhen urea is removed from the blood too quickly during dialysis, a net movement of fluid into the brain seems to occur. This is quite rare and causes headache, double vision, nausea and vomiting. Tremors and seizures may follow.

Dialysis dementia is a progressive disease found in some patients on long-term haemodialysis. The cause of this disease is still controversial, but thought to be due to the deposition of aluminum in the brains of those patients. In order to avoid this complication the water used for dialysis is purified by a process called reverse osmosis. The intake of aluminum-containing phosphate binders is also limited.

Central Nervous System Infections

Renal transplant recipients are predisposed towards developing CNS infection primarily because of drug induced suppression of cell mediated immunity. Other predisposing factors include uraemia, hyperglycaemia, and indwelling catheters. Infections of the CNS, often fungal in type, have been reported in up to 45% of transplant patients coming to postmortem.

The timing of the infection after transplantation may give a clue to the nature of the likely pathogens. Broadly speaking, three phases exist. In the first of these, the first month after transplantation, CNS infection is actually very uncommon. When it does occur, infection is usually either acquired from the donor kidney, is related to the surgical procedure itself, or was present before transplantation. Pathogens are typically those found in the general, non-immunosuppressed population.

The second phase extends from 1 to 6 months after transplantation. A combination of immunosuppressive drugs and the immunomodulating effect of common viruses means that immunosuppression is at its peak and the risk of CNS infection is greatest. Viruses and Epstein-Barr virus ) and opportunistic organisms predominate.

Does Acute Kidney Injury Affect Other Organs

Acute Kidney Injury is a common and serious condition with no specific treatment. AKI has been estimated to cost the NHS in the UK alone between £451-626 million per year. Recovery from a single episode of AKI is known to then increase risk of being diagnosed with chronic kidney disease later in life. However, many patients that recover from AKI also appear to be a greater risk of developing certain diseases of other organs distant or remote from the kidney such as the lung or liver. Why acute damage to the kidney may affect other organs is not known but it is thought that other organs may become infiltrated with inflammatory cells which affect their function in the longer term. Nearly all experimental studies to date on the remote effects of AKI have been conducted in laboratory rodents , which may not be clinically valid. Whilst clinical studies are preferred for investigating human disease humans are, after all, the best experimental animal model for humans clinical studies of AKI are often confounded by multiple comorbidities and tissue sampling of remote organs like the lung is difficult, risky and usually unethical. Epidemiological studies can suggest associations between AKI and effects on remote organs, but will not help understand the cause of the problem. Pigs are excellent biomedical models for human disease, especially renal disease. Here, we used a large animal model of AKI to investigate any potential remote effects.

An Ideal Parameter Or Panel Of Parameters To Assess The Toxicity Of Retained Compounds

In health, the renal glomerular filter cleanses the body of molecules with weights up to 58 kDa. All substances retained in the body as a result of renal dysfunction are potential uremic toxins. A retained substance to be classified as uremic toxin must meet the following criteria :

The chemical structure and composition should be identifiable and the substance should be quantifiable in biological fluids using a recognized methodology.

Concentrations in the biological fluids or tissues of patients with renal dysfunction should significantly exceed those in nonuremic subjects.

Increases in the concentration in the blood or tissue should correlate with the clinical manifestations.

The association between the biological activity and the clinical manifestations should be demonstrable in in vivo, ex vivo and in vitro test systems.

The following two sections outline areas in need of elucidation through further studies.

How Kidney Disease Causes Heart Problems

On the other hand, kidney disease often leads to cardiac problems. It does this in two major ways.

First, chronic kidney disease commonly produces salt and water retention, which can place significant strain on the heart. If any degree of underlying heart disease is present, whether it is CAD, heart valve disease or cardiomyopathy , this increase in the bodys fluid volume can cause cardiac function to deteriorate and can lead to overt heart failure.

Second, chronic kidney disease is a major risk factor for developing CAD, and for worsening any underlying CAD that might be present. People with chronic kidney disease who also have CAD tend to have significantly worse symptoms, and worse outcomes, than people who have CAD without kidney disease.

What Is Kidney Failure

Kidney failure means one or both kidneys can no longer function well on their own. Sometimes, kidney failure is temporary and comes on quickly. Other times, it is a chronic condition that can get worse slowly over a long time.

Kidney failure may sound serious, and it is. But treatments such as dialysis and kidney transplant help many people with limited kidney function continue to live fulfilling lives.
