Treatments For Anaemia In Kidney Patients

Kidney (Renal) Disease Signs & Symptoms (ex. Peripheral Edema, Fatigue, Itchiness)

Treating anaemia by increasing the amount of haemoglobin in the blood helps to restore energy, improve stamina for exercise, and may help improve other problems, such as problems with sexual function.

Iron concentrations are often low in people with kidney disease either because their diet doesnt contain enough iron, or theres something wrong with how the body absorbs iron from the food as it is digested. Extra iron is given to provide enough for normal production of red cells and to reverse or lessen the anaemia.

In the past, blood transfusion was the only really effective treatment for renal anaemia, but it had a number of problems:

  • Each transfusion could carry a small risk of infection by viruses in the blood.
  • Some peoples immune systems could mistake the cells in the blood transfusion for an invader and react by making antibodies to them. This could result in potential difficulties:
  • matching possible future kidney transplants
  • matching blood for further transfusions.
  • Patients could have allergic reactions during transfusions.
  • Repeated transfusions could lead to iron building up in the body, particularly in the heart and liver, causing damage to these organs.
  • Blood transfusions appear to reduce the bodys immunity to infection.
  • Side effects are rare but some are important, for example:

    The best level for haemoglobin if you have kidney disease is probably low-normal or a little bit lower than normal. This relieves the symptoms of anaemia without causing complications.

    Funding routine dental care for people at all income levels could potentially become a priority as a way to prevent kidney disease, and the cost savings would be significant, she said. Its certainly cheaper to pay for preventative dental care than dialysis.

    She also noted that both kidney disease and periodontal disease disproportionately impact poorer populations.

    Periodontal disease is an inflammatory response to persistent infection, caused by bacteria getting trapped in the gums porous tissues. Just as research indicates this inflamed state can affect major organs such as the heart, possibly through bacteria in the blood stream, studies show kidneys are similarly at risk, Grubbs said. Her goal is to prove this link in longitudinal research.

    Efficacy Of Hif Prolyl Hydroxylase Inhibitors

    Roxadustat is the most advanced HIF-PHI under clinical development, which has already been approved in China and Japan. Two phase 3 studies were published in 2019 comparing roxadustat with placebo in NDD, and with epoetin alfa in DD-CKD patients in China. These studies had a relative small sample size a study population and of short duration. The former compared roxadustat with placebo, without adjuvant iron supplements, and demonstrated its efficacy in rising hemoglobin levels after 9 weeks . The latter compared roxadustat with epoetin alfa, with iron supplement only as a rescue therapy. After 26 weeks of follow up, the attained hemoglobin levels in the roxadustat group were non-inferior to those in the epoetin alfa-arm, and both groups had a similar safety profile . These results were similar to those found by a phase 3 study comparing roxadustat to ESAs in hemodialysis and peritoneal dialysis patients in Japan .

    The OLYMPUS, ALPS, and ANDES trials evaluated roxadustat vs. placebo in NDD-CKD patients . An integrated analysis showed that roxadustat was efficacious in achieving and maintaining Hb levels, with lower risk of rescue therapy. Regarding adverse events, both arms of treatment had comparable safety profiles regarding cardiovascular events and all-cause mortality .

    Why Are The Kidneys So Important

    Most people know that a major function of the kidneys is to remove waste products and excess fluid from the body. These waste products and excess fluid are removed through the urine. The production of urine involves highly complex steps of excretion and re-absorption. This process is necessary to maintain a stable balance of body chemicals.

    The critical regulation of the body’s salt, potassium and acid content is performed by the kidneys. The kidneys also produce hormones that affect the function of other organs. For example, a hormone produced by the kidneys stimulates red blood cell production. Other hormones produced by the kidneys help regulate blood pressure and control calcium metabolism.

    The kidneys are powerful chemical factories that perform the following functions:

    • remove waste products from the body
    • remove drugs from the body
    • balance the body’s fluids
    • release hormones that regulate blood pressure
    • produce an active form of vitamin D that promotes strong, healthy bones
    • control the production of red blood cells

    Below you will find more information about the kidneys and the vital role they play in keeping your body functioning.

    How Does Renin Affect The Kidneys

    Therapeutic Advances in Chronic Kidney Disease: Management ...

    4.3/5reninkidneyrenin

    Consequently, what does renin do in the kidneys?

    Renin’s primary function is therefore to eventually cause an increase in blood pressure, leading to restoration of perfusion pressure in the kidneys. Renin is secreted from juxtaglomerular kidney cells, which sense changes in renal perfusion pressure, via stretch receptors in the vascular walls.

    Likewise, how do kidneys affect blood pressure? If the kidneysblood vessels are damaged, they may stop removing wastes and extra fluid from the body. Extra fluid in the blood vessels may then raise blood pressure even more, creating a dangerous cycle.

    Also know, how does renin affect urine production?

    ANP promotes natriurisis by shutting down the renin-angiotensin-aldosterone system and causing vasodilation. As the blood vessels expand, urine excretion of sodium and water increases, stabilizing blood volume and blood pressure.

    What would happen to your blood pressure if your kidneys could not regulate the production of renin?

    Without renin, blood pressure cannot be protected in the face of sodium depletion. Conversely, in the face of salt loss, excess renin production serves only to maintain, not to increase blood pressure. It is in salt-replete humans that renin may be undesirable and contribute both to hypertension and end-organ damage.

    Managing Anemia In Patients With Chronic Kidney Disease

    Chronic anemia affects the body negatively in a number of ways and decreases an animal’s quality of life.

    Chronic kidney disease and its progression have a number of detrimental effects on an animal’s body. The kidneys play a major role in multiple metabolic and endocrine functions, including controlling red blood cell production from bone marrow. In addition, uremia from progressive renal disease can shorten red blood cell survival.

    It is estimated that 32% to 65% of cats with CKD develop anemia as their disease worsens, and that as end-stage kidney disease approaches, almost all of these animals will develop anemia.1-3 Chronic anemia affects the body negatively in a number of ways and decreases an animal’s quality of life. Thus, it is important to recognize renal anemia in cats and dogs so the appropriate therapy may be implemented and the treatable causes of anemia corrected.

    Alcohol And Kidney Disease

    Drinking alcohol heavily can have several long-term health consequences including type 2 diabetes and high blood pressure. These conditions commonly lead to kidney disease. Excessive drinking is considered to be more than four drinks per day. This doubles your risk of developing chronic kidney disease or long-term kidney damage. The risk increases if youre a smoker.

    Kidneys that have been overworked due to excess alcohol consumption dont function properly. This makes them less able to filter blood and maintain the correct water balance in the body. The hormones that control kidney function can also be adversely affected.

    Heavy drinking can also cause liver disease, which makes your kidneys have to work harder. When you have liver disease, your body doesnt balance the flow and filtering of blood as well as it should. This has a harmful effect on your overall health and can increase the chance of complications.

    Infusion Medications For Iron Deficiency Anemia In Ckd

    To date there are two primary injection treatment options for anemia in patients with CKD: Aranesp and Procrit . Both of these treatments are synthetic erythropoietic stimulators that just like natural EPO enable your bone marrow to produce red blood cells. Successful treatments with Procrit or Aranesp will raise your hemoglobin levels and can reduce the need or frequency of blood transfusions.

    Recently, the FDA has also approved Retacrit for treatment of anemia due to CKD. Its a biosimilar product to Procrit, which means that the two drugs bear no clinically meaningful difference. Biosimilars can offer a more cost-effective option than their reference product, if your healthcare provider approves the treatment.

    How Does Eating Diet And Nutrition Affect Anemia In Ckd

    You may need to change what you eat to manage your anemia and CKD. Work with your health care professional or a registered dietitian to develop a meal plan that includes foods that you enjoy eating while maintaining your kidney health and managing your anemia.

    If your body doesnt have enough iron, vitamin B12, or folate, your health care professional or a dietitian may suggest that you add more foods with these nutrients to your diet. However, some of these foods have high amounts of protein, sodium, or phosphorus, which people with CKD may need to limit. Talk with your health care professional or a dietitian before making any changes to your diet.

    Alcohol And Kidney Stones

    Even though there is no direct causality between alcoholism and kidney stones, alcohol still has an impact on the formation of kidney stones. Drinking an excessive amount of alcohol frequently increases the risk of kidney stones substantially. Beer and grain alcohol can cause kidney stones due to their high concentration of purines. Purines are chemical compounds that can lead to uric acid kidney stones. Its because of this risk that creates a connection between alcohol and kidney stones.

    Excessively drinking alcohol can also lead to severe dehydration, which is one of the many reasons behind stone formation in the kidney. Calcium oxalate stones in particular can form when someone is dehydrated. Consistently drinking alcohol can create a pattern of dehydration while increasing the chance of kidney stones.

    Another factor can also be obesity and weight gain. Regardless of whether it is mild or severe, this alone can increase a persons chance of kidney stones. In the topic of alcohol and kidney stones, alcohol can end up leading to weight gain and may evolve into obesity. This creates a massive risk of kidney stones down the line .

    Consuming too much alcohol puts someone at a high risk of stone formation, however drinking a moderate amount can be beneficial. Strangely, white wine, red wine, and some kinds of beer can actually reduce a persons risk of kidney stones. While this can be seen as a positive some may abuse alcohol at an excessive rate .

    How Do Health Care Professionals Treat Anemia In Ckd

    Health care professionals first treat any underlying conditions that may be causing the anemia, such as an iron or vitamin deficiency. If your anemia is mild and you have few symptoms, you may not need treatment at first.

    Treatments for anemia may ease your symptoms and improve your quality of life.

    Your health care professional may refer you to a hematologist or a nephrologist, a health care professional who treats people with kidney problems or related conditions.

    Why Does Anemia Occur In Patients With Ckd

    Chronic kidney disease refers to lasting damage of the kidneys in which the patient progressively loses kidney function. In advanced stages, CKD can lead to total kidney failure without the assistance of dialysis to filter the blood or in some cases a kidney transplant. Anemia occurs when damaged kidneys are unable to produce a hormone called erythropoietin , which helps your bone marrow produce red blood cells. In the absence of adequate levels of EPO, the body becomes anemic and cannot supply your body with enough oxygen.

    How Is Anaemia Diagnosed

    Anaemia is diagnosed by blood tests. These will measure your blood count , iron levels , and levels of vitamin B12 and folate . This can confirm the type and severity of anaemia.

    If you are receiving dialysis you will have regular blood tests to monitor your anaemia. If you are not having dialysis you will probably just have your blood count measured in clinic, so if you experience any of the above symptoms you should discuss them with your doctor.

    What Tests And Procedures Diagnose Chronic Kidney Disease

    Chronic kidney disease usually causes no symptoms in its early stages. Only lab tests can detect any developing problems. Anyone at increased risk for chronic kidney disease should be routinely tested for development of this disease.

    • Urine, blood, and imaging tests are used to detect kidney disease, as well as to follow its progress.
    • All of these tests have limitations. They are often used together to develop a picture of the nature and extent of the kidney disease.
    • In general, this testing can be performed on an outpatient basis.

    Urine tests

    Urinalysis: Analysis of the urine affords enormous insight into the function of the kidneys. The first step in urinalysis is doing a dipstick test. The dipstick has reagents that check the urine for the presence of various normal and abnormal constituents including protein. Then, the urine is examined under a microscope to look for red and white blood cells, and the presence of casts and crystals .

    Only minimal quantities of albumin are present in urine normally. A positive result on a dipstick test for protein is abnormal. More sensitive than a dipstick test for protein is a laboratory estimation of the urine albumin and creatinine in the urine. The ratio of albumin and creatinine in the urine provides a good estimate of albumin excretion per day.

    You Don’t Have Enough Iron And Other Nutrients

    Your body needs iron to make red blood cells.

    About half of people with late-stage CKD don’t have enough iron. If you’re one of them, it could be because:

    • You get too little iron in your diet.
    • Your body doesn’t absorb iron well.
    • You’ve lost blood from having frequent dialysis or blood tests.

    When you lose blood, you lose iron, too.

    CKD can also leave your body low in other nutrients that it needs to make healthy red blood cells, including vitamin B12 and folate .

    When Should I Call The Doctor

    KIDNEY DISEASE BLOOD TEST – What is Erythropoietin (EPO)?

    A nephrologist receives special training in kidney evaluation and treatment. You may benefit from a kidney specialists expert opinion if:

    • You have trouble keeping your blood pressure levels in a normal range, even with medication.
    • Your blood sugar levels fluctuate widely.

    Where Are My Kidneys

    The kidneys are small bean-shaped organs approximately 6 cm wide and 12 cm long and consist of two main layers an inner layer called the medulla and an outer layer called the cortex. Most people have two kidneys that are situated at the back of the abdomen on either side of the spine.

    Allopathic Solution For Kidney Disease

    There are two treatment options for end-stage kidney disease: dialysis and kidney transplant. They are:

    • People opt for dialysis as it is a system for filtering waste products and excess fluids out of the blood. There are mainly two main types of dialysis namely, hemodialysis and peritoneal dialysis.
    • In hemodialysis, the blood is filtered outside of the body with the help of an artificial machine. In peritoneal dialysis, one fills the abdominal cavity with a special solution via a catheter. The solution absorbs excess fluid and waste before its drained from the body. Such dialysis usually needs to be done several times a week, so it may affect the lifestyle. Dialysis may also increase the risk of infection.
    • A kidney transplant is mostly done when dialysis is no longer possible. It requires an appropriate kidney donor. In this process, a kidney from a living sibling or other close relative is usually best. One can also get the kidney from a deceased donor. However, a kidney may fail if the body doesnt accept the replaced kidney. How Does Kidney Failure Affect Overall Homeostasis.
