Does your child have a kidney disorder? Do you know about the nephrotic syndrome? I think, you don't.
Are you child is having any problem related to kidney disorder? If maybe nephrotic syndrome. Read all the infromation realted to nephrotic syndrome.
Well, the kidney-related problems are comparatively rare, but it can be the reason of loss of valuable body protein and other sordid complications. As a mother, you require to be aware and prepared for any adverse situation. So here, we are providing all the possible related information on nephrotic syndrome in children. Keep reading continue and learn more.
What Is Nephrotic Syndrome In Children?
As we have mentioned before, Nephrotic syndrome is a kidney disorder. The kidneys begin to seep protein from the blood into the urine and do not act as they typically should . The condition happens due to some breakage done to the groups of tiny blood vessels present in the kidneys, which filter extra water and waste from the blood.
Nephrotic syndrome can affect adults as well as children. However, the disease predominantly affects children between the age of two to five. Children suffering from nephrotic syndrome are highly sensitive to infections and sometimes, their body tissues swell. The feet and ankles are first to become swollen.
:- Your child will show many symptoms of this condition. However, most symptoms can be treated with steroid-based medications. Sometimes, children suffering with nephrotic syndrome exhibit no severe symptoms and tend to be under control. However, at other times, the symptoms return with a vengeance,also referred to as a relapse. Doctors have detected that as children grow old, the relapse rate becomes less, and by the time they reach the age of 19 or 20, they hardly show any sign of the condition.
If children get the right treatment, generally steroids, the condition is curable, and children do not have to suffer kidney failure. However, if your child has hereditary nephrotic syndrome, treatment may not yield positive results, and chances are high your child will end up having kidney failure. If your child does have kidney failure, the only treatment is a kidney transplant.
Causes Of Nephrotic Syndrome In Children:
As mentioned above, this syndrome occurs due to damage to the groups of small blood vessels present in the kidneys. These blood vessels are known as glomeruli. Their primary task is to infiltrate blood while it is passing through the kidneys and to detach the crucial things that your body needs from those which it does not.
When the glomeruli are healthy, they stop albumin, a type of blood protein, from seeping into the urine that passes out from the body. However, when they are damaged, they allow excessive amounts of this essential blood protein pass out of the body through the urine which leads the development of nephrotic syndrome.
Some of the most common causes of nephrotic syndrome in children are:
1. Thickening Of Glomeruli Membranes:
A kidney condition known as membranous nephropathy occurs when the membranes inside the glomeruli thicken. Doctors believe other diseases and health conditions such as lupus, cancer, malaria and hepatitis B, lead to the thickening of these membranes. This, in turn, leads to nephrotic syndrome.
2. Blood Clots:
When a blood clot blocks a vein leading to the kidney, it can result in nephrotic syndrome. This condition is medically called renal vein thrombosis.
Childhood diabetes can damage the kidneys if it is not diagnosed. This damage is known as diabetic nephropathy. When the kidneys get damaged, it leads to nephrotic syndrome in kids.
4. Amyloid Buildup:
If your child suffers from amyloidosis, it causes severe damage to the kidneys. The filter system of the kidneys gets affected. Amyloidosis is the buildup of amyloid, a type of protein, in the organs.
5. Irregular Functioning Of The Heart:
If your child suffers from a serious heart condition, it cannot pump blood to the vital organs. Hence, kidneys do not get sufficient blood and nutrients to function optimally, resulting in nephrotic syndrome.
6. Minimal Change Disorder:
This, perhaps, is the most common reason for nephrotic syndrome in kids. This disorder happens due to excessive use of OTC medications, tumors, infections, and allergic reactions. It involves abnormal functioning of the kidneys. When the kidney tissue sample is checked under a microscope, it appears normal and healthy. However, if a problem with the kidneys exist, it is tough to determine.
7. Chronic Inflammatory Disease:
Some chronic inflammatory diseases such as systemic lupus erythematosus, can damage the kidneys, preventing them from functioning normally. When this happens in your child, it leads to nephrotic syndrome.
8. Scattering Of Glomeruli:
Scattering of glomeruli, also known as focal segmental glomerulosclerosis, occurs due to a genetic defect. It leads to scarring of the inner part of the kidneys. This condition leads to chronic nephrotic syndrome, as hereditary problems cannot be treated.
Other Causes For Nephrotic Syndrome In Children:
Sometimes nephrotic syndrome can develop in children due to other diseases or conditions like:
- Sickle cell anemia
- Glomerulonephritis (inflammation of the kidney)
- Cancers like lymphoma, leukemia and multiple myeloma
- Infections like hepatitis, untreated strep infection and HIV
- Certain medications like aspirin and NSAIDs
- Exposure to dangerous chemicals like lithium and mercury
- Inherited genetic defects
- Infections contracted at birth
Symptoms Of Nephrotic Syndrome In Children:
Following are the signs and symptoms that your child will exhibit if he suffers from nephrotic syndrome:
1. Changes In The Urine:
If your child is suffering from nephrotic syndrome, protein from the body leaks into the urine. This occurs because the kidneys do not function properly. Due to excessive protein (albumin) in the urine, the child will have frothy urine. Also, your little one will pass less urine than normal.
2. Edema Or Swelling Of Tissues:
Nephrotic syndrome causes swelling around the legs, feet, and ankles. Many times, even the face and hands can swell. The swelling occurs due to low protein content in the blood which reduces the flow of water from the tissues to the blood vessels.
When the doctor examines your child’s blood, it will have high levels of cholesterol and fats. This is a sign of nephrotic syndrome.
This is a condition in which your kid’s blood will show low levels of albumin, a necessary protein. This protein instead of being present in the blood leaks into the urine if the child is suffering from nephrotic syndrome.
5. Paleness Of The Skin:
If your child appears pale along with edema, it is a sign of nephrotic syndrome. You should never neglect it and take your child to the doctor immediately.
Your child may also show other symptoms of nephrotic syndrome, which include:
- Presence of blood in the urine
- Appetite loss
- Infections with fever
- Abdominal pain
- Elevated blood pressure.
Diagnosis Tests For Nephrotic Syndrome In Children:
When you take your child to a nephrologist, he may perform the following diagnostic tests to detect whether your child is suffering from nephrotic syndrome.
1. Blood Test:
If your child suffers from edema and looks pale, doctors will recommend to conduct a blood test. This test checks the blood for albumin and presence of cholesterol and triglycerides.
If the level of the protein is low in the blood, it is a clear sign that your child has nephrotic syndrome. Also, such a child will have high levels of cholesterol and blood triglycerides.
Sometimes, the pathologist may check the blood of blood urea or serum creatinine as well. This allows the doctor to assess the functioning of your kid’s kidneys.
2. Urine Tests:
Urine test helps the doctor to find out the level of albumin in the urine. If the protein level in the urine is high, the doctor will suggest a second test. This ensures accuracy.
A urine test also helps in finding out kidney infections, which can result in symptoms similar to nephrotic syndrome.
This test is performed using a needle and does not need any surgery. For this test, the doctor will need to take a small piece of your child’s kidney tissue as a sample for testing. This kidney sample is sent to a laboratory for testing.
A doctor will recommend a kidney biopsy only if he believes your child has severe nephrotic syndrome and other forms of treatment are not working satisfactorily.
4. Kidney Ultrasound:
This outpatient procedure allows the doctor to view images of the kidney and its insides for abnormalities. It does not require anesthesia and is completely safe and painless. So you needn’t worry.
Also, the doctor will perform a physical test by examining your child’s body and tapping specific areas of the body. Be ready with your family history, as the doctor will ask you about your family medical history.
Treatments For Nephrotic Syndrome In Children:
Nephrotic syndrome treatment in children depends on whether the syndrome is primary or secondary. The primary is when the condition develops and restricts to the kidneys. The secondary nephrotic syndrome is when the condition occurs due to some other health problem.
Usually, the first line of treatment for nephrotic syndrome in children is steroid-based medication. However, the doctor may recommend other treatments if your child develops serious side effects to the steroids.
Doctors usually recommend that children take steroid medications when they are suffering from a relapse or low urine output. It is best to take your child to a pediatric nephrologist (a kidney specialist for children) for diagnostic testing and subsequent treatment.
The treatments for managing nephrotic syndrome in kids are as follows:
Initially, the specialist may recommend your child take prednisolone for about six weeks. This is a steroid-based medication. If this happens, make sure your child takes the medication diligently as advised by the doctor.
Sometimes, the doctor may suggest an extension in the course of the medicine for another six weeks. But this time, your little one will have to take the medicine on alternate days.
Prednisolone prevents the excessive protein from leaking into the urine. It does not have a harmful side effect if your kid takes it according to the doctor’s directive. However, there are a few side effects that you may notice, but they are not of major concern, which include:
- Swelling of the cheeks
- Sudden weight gain
- Mood swings
- Unusual increase in appetite
Steroid-based medicines are most successful in dealing with nephrotic syndrome in children. They have the ability to prevent protein leakage into the urine. Also, these medications reduce the edema that your child may have.
Doctors also suggest that children suffering from nephrotic syndrome take certain vaccinations, like a pneumococcal vaccine and the chickenpox or varicella vaccine, to keep infections at bay.
However, your child should not receive vaccines like BCG, MMR, and varicella vaccine if he is taking other medications to control the symptoms of nephrotic syndrome.
3. Anticoagulants Or Blood Thinners:
These blood thinners, also known as anticoagulants, prevent the blood from clotting and significantly lower your child’s chances of developing blood clots.
Blood clots can develop when a child has nephrotic syndrome, and these clots can be life-threatening.
4. Water Tablets Or Diuretics:
Diuretics help in controlling swelling of the body tissues by increasing fluid output of the kidneys. They cut down on the buildup of fluid within the body. They also help by increasing urine production.
If your child has elevated blood pressure, diuretics can bring down the pressure, as well.
5. Immune System Controlling Medication:
If your child relapses or does not respond to corticosteroids, the doctor may put him on other medication control the working of the immune system. This medication stops the body from manufacturing antibodies, which can damage the kidneys.
In case, the doctor thinks your child is at a risk of catching an infection, he will take preventive measures by prescribing penicillin. If your child is allergic to penicillin, do inform the doctor. He will prescribe an alternative antibiotic.
7. Infusions Of Albumin:
Nephrotic syndrome results in loss of protein from the body. This protein passes out of the body through urine. If the loss of albumin from the body is severe, your child will need hospitalization to receive infusions of albumin.
The doctor will insert a cannula, which a thin plastic tube, into a vein in the arm so that the albumin can slowly transfer to the blood, boosting the level of the protein in the blood.
8. Medications To Reduce Cholesterol Levels:
Medications called statins help in lowering blood cholesterol levels. However, doctors are still puzzled whether these statins can help a person avoid heart attacks or lower the risks of dying at an early age. Nonetheless, statins will help reduce the high cholesterol levels that your child has.
9. Medications To Reduce Blood Pressure:
Medications called angiotensin-converting enzyme inhibitors help in lowering blood pressure and also reduce how much protein is leaking through the urine. These angiotensin-converting enzyme inhibitors include medicines like enalapril, benazepril, and captopril. There is another group of similar medications called angiotensin II receptor blockers which include valsartan and losartan. The doctor will decide which group is the best for your child.
There are certain additional medications that the doctor may prescribe if these treatments do not yield positive results. These medications help in reducing relapses and also control the symptoms of nephrotic syndrome.
10. Dialysis and Kidney Transplant:
In case your child does not respond to treatment, the doctor may suggest removing one or both his kidneys. This reduces the risk of blood clots. If this happens, your child will be put on dialysis that takes the function of the kidneys. This will continue until your kid receives a kidney transplant.
Your child requires just one kidney for survival. You or any other family member can donate a kidney if the need arises .
Prevention Tips For Nephrotic Syndrome In Kids:
You cannot prevent nephrotic syndrome if it is congenital or idiopathic. However, you can prevent your kid from getting relapses.
1. Preventing Colds And Other Infections:
Nephrotic syndrome is a group of symptoms and it makes your kid vulnerable to infections. Many healthcare practitioners believe a damaged immune system can result in problems for the kidneys.
You can prevent relapses in your child by protecting him from common infections. This means to maintain good hygiene and cleanliness.
2. Careful Diet Management:
A child with nephrotic syndrome is usually put on a special diet. Make sure your kid consumes a low-protein, low-sodium and low-phosphorus diet.
Since nephrotic syndrome causes edema, salty food can aggravate the swelling further. And, foods high in protein and phosphorus make renal disorders worse by burdening the malfunctioning kidneys.
3. Natural Treatments:
Even though steroid medications are highly effective in treating nephrotic syndrome in children, they, sometimes, lead to severe side effects. Hence, doctors may recommend natural therapy. These natural treatments help to repair the damage to kidneys and also help improve the functioning of the kidneys. Also, natural treatments do not have any harmful side effect.
4. Lifestyle Changes:
Many doctors recommend children suffering from nephrotic syndrome should regularly exercise to prevent relapse. However, these exercises should be mild and not very strenuous. Never send your child for a sport like taekwondo or wrestling if he has nephrotic syndrome. Instead, encourage him to take up other physical activities like swimming, jogging, hiking, and walking.
Risks And Complications Of Nephrotic Syndrome In Children:
Certain factors can increase your child’s chances of developing nephrotic syndrome. Some of them are:
Certain infections like malaria, hepatitis B, hepatitis C and HIV can increase the chances of your child getting nephrotic syndrome.
2. Other Medical Conditions:
Other health conditions such as amyloidosis, diabetes, lupus and minimal change disease also increase the chances of your kid developing nephrotic syndrome.
NSAIDs or nonsteroidal anti-inflammatory drugs which fight off infections could lead to nephrotic syndrome if you overdose your child.
There are also certain complications which your kid can experience if he has nephrotic syndrome.
Due to leakage of protein through the urine, your child will probably be malnourished and may also experience weight loss and anemia (low red blood cell content). Your child’s calcium and Vitamin D levels may also be affected.
- Blood Clots:
Nephrotic syndrome often results in the glomeruli being unable to filter blood effectively, and this increases a number of proteins leaking out through the urine. Your child’s chances of developing a blood clot are extremely high in such a case.
- Long-Term Kidney Disease:
As nephrotic syndrome impairs the functioning your kid’s kidneys, in the long run, the kidneys stop working completely. Under such circumstances, your child may require lifelong dialysis or get a kidney transplant.
- High Blood Pressure:
Since the kidneys do not function properly, it causes waste to accumulate in the blood, resulting in elevated blood pressure.
- Kidney Failure:
If the glomeruli get damaged severely, your kid’s kidney will be unable to filter the waste. This leads to the buildup of waste material in the blood. In such a case, your child will require dialysis to remove this buildup of waste and excessive fluid from the body and blood.
- High Blood Cholesterol Level:
Due to nephrotic syndrome, the albumin levels in the body get dangerously low. This causes the liver to increase production of albumin. However, the increase in the protein also causes cholesterol and triglyceride levels to elevate, resulting in high blood cholesterol.
- Increased Risk Of Infections:
As mentioned earlier, your child will be at a higher risk of getting infections if he suffers from nephrotic syndrome. Even a common cold can be dangerous for your kid.
Home Remedies For Nephrotic Syndrome In Children:
Unfortunately, there aren’t any home remedies for nephrotic syndrome. However, with a few lifestyle changes, you can improve your child’s quality of life. The most important thing is to make serious changes to your child’s diet to help the kidneys.
Some of the lifestyle changes your can incorporate are:
- Do not give your child salty foods, as this will worsen edema brought on by nephrotic syndrome.
- Try introducing lean meats into your child’s diet to keep cholesterol levels low, but help with protein and iron levels.
- Cut down on the fat and cholesterol in the food that you give your child.
As a parent, you may worry when the doctor tells you your child has nephrotic syndrome. There is a silver lining, though. The condition goes away for good by the time your child turns into a teenager and that too without damaging the kidneys. However, until this happens, make sure that you are properly following the doctor’s instructions and providing your child the right treatment he requires.
