Specific treatment of nephrotic syndrome depends on the disease's cause

Nephrotic syndrome

Nephrotic syndrome can occur in anyone. The syndrome arises for many reasons, including a condition known as minimal change disease in children and glomerulonephritis (kidney inflammation) in adults. Nephrotic syndrome can also be caused by infection, medication side effects, heredity, cancer, and autoimmune disorders, such as diabetes and lupus.

The role of preventive anticoagulation in nephrotic syndrome has been reported, but there is no proof that it is beneficial.

Hyperlipidemia occurs in nephrotic syndrome, and it can be controlled with lipid-lowering agents. Older studies have reported a predisposition to atherosclerosis in patients with nephrotic syndrome, but there are no data to show that lipid-lowering drugs improve renal or patient outcomes.

Specific treatment
Specific treatment of nephrotic syndrome depends on the disease's cause. In minimal-change nephropathy, glucocorticosteroids, such as prednisone, are used.[35] Children who relapse after successful use of prednisone or who do not respond to prednisone (ie, those with steroid-resistant disease) may be treated with rituximab, an antibody against B-cells. Rituximab has also been used in membranous nephropathy in adults.[36]

In some forms of lupus nephritis, prednisone and cyclophosphamide are useful.

Secondary amyloidosis with nephrotic syndrome may respond to anti-inflammatory treatment of the primary disease.

Diet and activity
The diet in patients with nephrotic syndrome should provide adequate energy (caloric) intake and adequate protein (1-2 g/kg/d). Supplemental dietary protein is of no proven value. A diet with no added salt will help to limit fluid overload.

Management of hyperlipidemia could be of some importance if the nephrotic state is prolonged. Fluid restriction per se is not required.

There are no activity restrictions for patients with nephrotic syndrome. Ongoing activity, rather than bedrest, will reduce the risk of blood clots.

How the Kidneys Work
The kidneys are a pair of bean-shaped organs located toward the back of the abdominal cavity, just above the waist. The kidneys remove waste products and extra water from the food a person eats, returning chemicals the body needs (such as sodium, phosphorus, and potassium) back into the bloodstream. The extra water combines with other waste to become urine (pee).

The main functional units of the kidneys, where the blood filtering happens, are tiny organs called nephrons. Each kidney has about a million nephrons, and each nephron has one glomerulus (singular of glomeruli) — a ball of tiny blood vessels, or capillaries. The glomerulus is the nephron's filter. This is where the process of removing waste products and fluids from the blood begins.

When the glomeruli stop filtering properly, they allow too much protein to leave the blood. Protein helps hold fluids in the blood, so when there is less protein in the blood, the fluids can move to other parts of the body and cause a type of swelling (edema) in the face, belly, hands, arms, and other extremities. When this happens, it's called nephrotic syndrome.

IgA nephropathy is a common cause of glomerulonephritis

IgA nephropathy

IgA nephropathy is a common cause of glomerulonephritis. Although it is a benign disease in most patients, chronic renal failure and ESRD occur in about 20-40% of patients within 20 years of presentation. Currently, no cure exists for IgA nephropathy, but therapies that can delay the onset of need for dialysis and transplantation are available.

Monitor patients with isolated hematuria without proteinuria or hypertension with urinalysis, renal function testing, and blood pressure measurement.
Treat hypertension early and aggressively. A reasonable goal is to aim for BP of 125/75-130/80mmhg.[6]
ACE inhibitors are the preferred agents for lowering blood pressure.

The decrease in proteinuria with ACE inhibitors may be an effect of decreasing the intraglomerular pressure and of changing the glomerular size selectivity.
Reports have demonstrated that ACE inhibitors are more effective than other antihypertensive drugs in slowing the progression of proteinuric renal disease.
The goal for proteinuria control is 500mg/day or less, so ACE inhibitors or ARBs should be started in patients with 24-hour urine protein of 500 mg or more.

Angiotensin II receptor blockers should be used for patients who cannot tolerate ACE inhibitors. ACE inhibitors and angiotensin II receptor blockers may have an additive effect in decreasing proteinuria. Whether high doses of ACE inhibitors better preserve renal function than combined therapy with ACE inhibitors and angiotensin II receptor blockers is unknown.

patients with advanced kidney failure.
Administer prednisone for 4-6 months to patients who have IgA nephropathy with preserved renal function, nephrotic syndrome, and minimal-change findings on light microscopy.

Manno et al, in a prospective, open-label, multicenter, centrally randomized, controlled trial, investigated whether the use of a corticosteroid in combination with an ACE inhibitor would be more effective in treating patients with IgA nephropathy than would an ACE inhibitor alone.[8] Results of the trial, in which 49 patients with IgA nephropathy were administered the ACE inhibitor ramipril and 48 patients were given ramipril plus prednisone, suggested that the combination treatment was more effective than the ACE inhibitor alone in discouraging progression of renal disease associated with IgA nephropathy.

How is IgA Nephropathy diagnosed?

Blood in the urine can be caused by many things. Because so few doctors are familiar with IgAN, a patient may be put through extensive urological tests to determine if there is a urinary tract infection or congenital abnormality. But if the red blood cells in the urine are examined under a microscope, they appear dysmorphic [strangely shaped]: instead of being full and round, they look as if they’d been nibbled around the edges. This is a tip-off that glomerulonephritis is involved, but it does not tell the doctor which glomerulonephritis it might be.

A physician may first believe that this is post-streptococcal glomerulonephritis [PSGN], a disease that resembles IgAN in some ways (but which, unlike IgAN, tends to resolve itself spontaneously). To assist the diagnosis, the doctor performs a variety of tests, including a complete blood count, blood-urea-nitrogen [BUN], serum creatinine, and ASO titers to rule out the possibility of post-streptococcal glomerulonephritis.

Your doctor may also order a creatinine clearance test. Based on a 24-hour urinalysis, this test ascertains how well they kidneys are performing their vital task of clearing creatinine, the end product of muscle metabolism, from the blood. The results show the kidneys’ glomerular filtration rate. This test is not diagnostic of a particular disease but, rather, of the severity of the inflammation and, possibly, the extend of damage to the kidneys. Your kidneys ordinarily filter about five ounces of blood each minute, but in IgAN, the filtration rate may decline because infiltration of the glomerular capillaries by inflammatory cells reduces the amount of surface area available for filtering work.

Causes of CKD

CKD

Causes of CKD

There are numerous causes of CKD, ranging from inflammations such as glomerulonephritis to congenital abnormalities such as certain polycystic kidney diseases. However, the most common causes of CKD are diabetes and hypertension.

Diabetes may affect the kidneys in two ways. One is by damaging the blood vessels inside the kidneys; the other is through nerve damage. If the blood vessels in the kidney are damaged, they cannot properly filter all the waste products out of the blood appropriately. If diabetes damages the nerves of the bladder this may lead to increased pressure in the bladder due to incomplete emptying. The increased pressure in the bladder can back up and result in injury to the kidneys.

Hypertension is unique in that it can cause CKD or be the result of it. Hypertension can cause damage to the arteries resulting in insufficient blood flow to the kidneys, leading to CKD. One function of the kidney is to produce hormones to help regulate blood pressure. When CKD is present, hypertension may result due to a disruption to this process.

CKD can develop at any age; however, it is more common as a person ages. Other risk factors besides certain diagnoses are patients with a family history of CKD, African Americans, Hispanics, Pacific Islanders, and Native Americans. It is important for high-risk patients to be routinely evaluated for CKD, as the signs and symptoms of the disease may go undetected until the disease has progressed.

Diagnosis and treatment of glomerulonephritis

Glomerulonephritis

Glomerulonephritis is a disease of the kidneys in which there is inflammation of the filtering units, called glomeruli. This inflammation can cause protein and red blood cells to leak into the urine while toxins normally removed by the kidney are retained in the body. Kidney failure develops when the kidney becomes less effective at filtering out waste products, water and salt from the blood.

There are many types and causes of glomerulonephritis.

Prior infection: For example, after a streptococcal infection (such as strep throat), kidney failure may develop with associated problems of high blood pressure, dark urine, and swelling in the legs. Glomerulonephritis following streptococcal bacterial infection is among the most common types of post-infectious disease, especially among children.
Autoimmune: With conditions such as systemic lupus erythematosus (SLE) or blood vessel inflammation (vasculitis), the body's immune system mistakenly attacks healthy tissue. When the kidney's filtering system is the target, glomerulonephritis may develop.
Antibody-mediated: The most common type is called IgA nephropathy. While this can be associated with liver disease, celiac disease or HIV infection, many cases are of unknown cause. Immunoglobulin A, an antibody that normally helps fight off infection, is deposited in the kidney, leading to hematuria (blood in the urine) but less commonly more serious problems.
Membranous glomerulonephritis: This condition may develop as part of lupus or on its own. The hallmark of this type of kidney disease is the leakage of protein into the urine.
Rapidly progressive glomerulonephritis: This condition may be diagnosed when there is kidney inflammation and loss of kidney function over weeks to months. Triggers include infections, autoimmune disease, and certain types of antibody-mediated kidney disease.
Idiopathic: When glomerulonephritis develops for no apparent reason it is called "idiopathic." It's possible that an undetected or undiagnosed infection or a hereditary cause led to kidney inflammation and damage.
Symptoms

If glomerulonephritis is mild, it may not cause any symptoms. In that case, the disease may be discovered only if protein or blood is found in the urine during a routine test. In other people, the first clue can be the development of high blood pressure. If symptoms appear, they can include swelling around the feet, ankles, lower legs, and eyes, reduced urination and dark urine (due to the presence of red blood cells in the urine).

High levels of protein in the urine can cause the urine to appear foamy. If severely elevated blood pressure develops, some people will have headaches (although most people with high blood pressure have no symptoms and most headaches are unrelated to blood pressure). Fatigue, nausea and tremulousness are other common symptoms of kidney failure due to glomerulonephritis. In severe cases, confusion or coma may develop.

Diagnosis

Your doctor will ask you about symptoms of a prior infection, family history, or symptoms of conditions that can affect the kidneys. For example, joint pain and rash are the most common symptoms of lupus. Your doctor will ask how often you are urinating, how much urine you are producing and the color of the urine. To check for a history of swelling, your doctor may ask whether you've noticed puffiness around your eyes, unusual tightness in your shoes or waistband or a feeling of heaviness in your legs or ankles.

During your physical examination, your doctor will measure your blood pressure, weigh you to check for weight gain resulting from water retention, and check for swelling in your legs or elsewhere. A complete physical examination is important to look for evidence of other organ involvement such as arthritis or rash.

To confirm the diagnosis of glomerulonephritis, your doctor will evaluate your kidney function through blood tests and an analysis of the urine (called a urinalysis) that detects blood, protein or signs of infection. You also may need specialized blood testing to check for specific autoimmune disease. A kidney biopsy, in which a tiny piece of kidney tissue is removed and examined in a laboratory, is the most helpful test when glomerulonephritis is suspected.

Expected Duration

How long glomerulonephritis lasts depends on its cause and on the severity of kidney damage. When glomerulonephritis follows an infection, the problem usually goes away within weeks to months. In other cases, glomerulonephritis becomes a chronic (long-lasting) condition that lasts for years and eventually can lead to kidney failure.

Treatment

When glomerulonephritis is caused by an infection, the first step in treatment is to eliminate the infection. If bacteria caused the infection, antibiotics may be given. However, children who develop the disease following a streptococcal infection often recover without any specific treatment.

When glomerulonephritis has slowed the amount of urine a person is producing, he or she may be given medications called diuretics, which help the body to rid itself of excess water and salt by producing more urine. More severe forms of the disease are treated with medications to control high blood pressure, as well as changes in diet to reduce the work of the kidneys. Some people with severe glomerulonephritis may be treated with medications called immunosuppressive drugs, which decrease the activity of the immune system. Such medications include azathioprine (Imuran), corticosteroids (Prednisone, Methylprednisolone), cyclophosphamide (Cytoxan), rituximab (Rituxan) or mycophenolate mofetil (CellCept). Plasma exchange, a procedure during which substances thought to cause inflammation and kidney damage are removed from the blood, can be helpful in certain types of autoimmune or antibody-mediated glomerulonephritis. When glomerulonephritis progresses to severe, irreversible renal failure, treatment options include dialysis or a kidney transplant.

Prevention and treatment of glomerulonephritis

Glomerulonephritis

Glomerulonephritis is a group of diseases that injure the part of the kidney that filters blood (called glomeruli). Other terms you may hear used are nephritis and nephrotic syndrome. When the kidney is injured, it cannot get rid of wastes and extra fluid in the body. If the illness continues, the kidneys may stop working completely, resulting in kidney failure.

Are there different types of glomerulonephritis?
Yes. There are two types of glomerulonephritis—acute and chronic. The acute form develops suddenly. You may get it after an infection in your throat or on your skin. Sometimes, you may get better on your own. Other times, your kidneys may stop working unless the right treatment is started quickly. The early symptoms of the acute disease are:

puffiness of your face in the morning
blood in your urine (or brown urine)
urinating less than usual.
You may be short of breath and cough because of extra fluid in your lungs. You may also have high blood pressure. If you have one or all of these symptoms, be sure to see your doctor right away.

The chronic form may develop silently (without symptoms) over several years. It often leads to complete kidney failure. Early signs and symptoms of the chronic form may include:

What causes acute glomerulonephritis?
The acute disease may be caused by infections such as strep throat. It may also be caused by other illnesses, including lupus, Goodpasture's syndrome, Wegener's disease, and polyarteritis nodosa. Early diagnosis and prompt treatment are important to prevent kidney failure.

What causes chronic glomerulonephritis?
Sometimes, the disease runs in the family. This kind often shows up in young men who may also have hearing loss and vision loss. Some forms are caused by changes in the immune system. However, in many cases, the cause is not known. Sometimes, you will have one acute attack of the disease and develop the chronic form years later.

How is a diagnosis of glomerulonephritis made?
The first clues are the signs and symptoms. Finding protein and blood cells in your urine is another sign. Blood tests will help the doctor tell what type of illness you have and how much it has hurt your kidneys.

1, the prevention of chronic glomerulonephritis, first of all to be positive prevention and treatment of acute nephritis, to avoid inadequate treatment, which is the main measures to prevent chronic nephritis acute conversion from.

2, reduce the thick greasy help wet injured spleen food intake, do regular diet, Paul acquired in order to raise a priori. Salt into the kidney, excessive eating salty foods can damage the kidneys, especially in times of acute nephritis, the appropriate limit salt intake.
Especially in patients with edema symptoms, you should limit the intake of salt, specific dosage limits should be based on the patient's specific condition, according to the patient's edema, blood pressure change as the basis. The daily food but also pay attention to balanced nutrition diversification, in order to enhance the body's resistance to disease.

3, to avoid damage to the kidney drugs, such as gentamicin, kanamycin, polymyxin and neomycin. Medicine such as Akebia, large doses of renal toxicity should be noted.

4, usually pay attention to prevent tired, to avoid the application of damage righteousness drugs and traditional Chinese medicines and kidney damage, especially to avoid the infringement of the wind, cold, wet, hot, poisonous evil. Timely treatment of exogenous disease and eliminate the infection of the mouth, hands, ears, throat, etc., chronic glomerulonephritis and disease prevention is important.
Chronic glomerulonephritis to prevent upper respiratory tract infection, tonsillitis, acute and chronic pharyngitis. For patients not infected with decreased immune function, commonly used Yupingfeng oral liquid, or Huang oral liquid. Infected patients should be treated in time, Western medicine commonly used penicillin, Chinese medicines Yinqiaosan, Banlangen granules, silver yellow oral solution.
Patients with high blood pressure, such as urine appear red blood cells may make use of Qi Ju Di Huang Wan or the Liver Yishenhuoxue and network of Chinese medicine. In patients with hypertension, should actively control blood pressure, renal hypertension is often heavy in winter, summer light, attention should be to adjust the dose.

Iga nephropathy symptoms Profile

Iga nephropathy

IgA nephropathy is a progressive condition, and it can take decades before you experience any symptoms. Sometimes, during a routine screening your doctor may detect signs of IgA nephropathy.

In many parts of the world, IgA nephropathy is the most common form of glomerulonephritis--a disease that damages the tiny filtering units of the kidney, called glomeruli. The damage caused by IgA nephropathy results from abnormal deposits of a protein called "IgA" in the glomeruli.

IgA is a protein called an antibody that helps the body fight infections. IgA nephropathy (Berger's disease) occurs when too much of this protein is deposited in the kidneys. IgA builds up inside the small blood vessels of the kidney. Structures in the kidney called glomeruli become inflamed and damaged.

IgA nephropathy (Berger's disease) is a form of mesangial proliferative nephritis.

The disorder can appear suddenly (acute), or get worse slowly over many years (chronic glomerulonephritis).


One of the kidney's most important jobs is to filter toxic waste products from the blood, and the glomeruli play a key role in this process. As more glomeruli are damaged by the IgA protein, the kidney progressively loses its ability to clear wastes from the body. In some patients with IgA nephropathy, this loss of kidney function progresses to chronic kidney failure, which requires dialysis treatment or a kidney transplant.

What are the signs and symptoms of IgA nephropathy?
The most common sign is blood in the urine. The amount of blood may be so small that it is only visible with the aid of a microscope. Another common sign is swelling of the feet.

What causes IgA nephropathy?
The causes of IgA nephropathy are not well understood. The disease seems to cluster in certain families and in certain areas of the world. It rarely occurs in people of African heritage. These facts suggest that genetic influences may play a role in the development of the disease.

How is IgA nephropathy diagnosed?
The presence of blood or protein in the urine are a possible sign of IgA nephropathy. A blood test for serum creatinine can be used to calculate glomerular filtration rate (GFR), which tells how well your kidneys are filtering wastes from the blood. To confirm this diagnosis, it is necessary to do a biopsy. The doctor removes a small piece of tissue from the kidney and examines it under a microscope to look for the characteristic IgA deposits in the glomeruli.

How is IgA nephropathy treated?
Efforts to slow the progression of kidney damage may include limiting the amount of protein in the diet and, if present, careful control of high blood pressure through diet and medication. If these treatments are not enough after a few months, then corticosteroids, such as prednisone, may also be considered. Fish oil has also been used as a treatment. Discuss the use of any supplement and medication with your doctor. For patients who develop progressive kidney failure, treatment may consist of dialysis or a kidney transplant.

The success rate of transplants is good in these patients. Even though the IgA deposits reappear in the transplanted kidney in about half the patients within one year after the operation, the signs and symptoms of the disease remain mild. Loss of a transplanted kidney to recurrent IgA nephropathy is uncommon. The milder form of the disease seen after transplantation may be due to the use of anti-rejection drugs such as cyclosporine.
