Treating proteinuria mainly needs proper diagnosis of the cause.
The most common cause is diabetic nephropathy; in this case, proper glycemic control may slow the progression. Medical management consists of angiotensin converting enzyme (ACE) inhibitors, which are typically first-line therapy for proteinuria. In patients whose proteinuria is not controlled with ACE inhibitors, the addition of an aldosterone antagonist (i.e., spironolactone) or angiotensin receptor blocker (ARB) may further reduce protein loss. Caution must be used if these agents are added to ACE inhibitor therapy due to the risk of hyperkalemia.
Proteinuria secondary to autoimmune disease should be treated with steroids or steroid-sparing agent plus the use of ACE inhibitors.
Early and aggressive treatment is required to control the disorder. Diuretic medications help rid the body of excess fluid. ACE inhibitor medications (like Captopril and others) and non-steroidal anti-inflammatory drugs (like indomethacin) are used to slow the spilling of protein (albumin) in the urine. Antibiotics may be needed to control infections. Patients may also take iron supplements, potassium chloride, thyroxine and other vitamins to replenish what minerals the kidneys have leaked out.
Most patients will undergo regular and frequent albumin infusion (often daily) to replace what kidneys have lost. Infusions are performed via IV so a central venous catheter will need to be surgically inserted into patients chest or groin.
Dietary modifications may include the restriction of sodium and use of dietary supplements as appropriate for the nature and extent of malnutrition. Fluids may be restricted to help control swelling.
Many patients have a gastrostomy tube (g-tube) inserted for medication and/or feeds. Some patients develop oral aversions and will use the tube for all feeds. Other patients eat well and only use the tube for medicine or supplemental feeds. The tube is also useful for patients needing to drink large amounts of fluids around the time of transplant.
Patient will require removal of the kidneys (one at the time or both), dialysis, and ultimately a kidney transplant.
Corticosteroids such as prednisone are often prescribed along with a blood pressure medication, typically an ACE inhibitor such as lisinopril. Some nephrologists will start out with the ACE inhibitor first in an attempt to reduce the blood pressure's force which pushes the protein through the cell wall in order to lower the amount of protein in the urine. In some cases, a corticosteroid may not be necessary if the case of minimal change disease is mild enough to be treated just with the ACE inhibitor. Often, the liver is overactive with minimal change disease in an attempt to replace lost protein and overproduces cholesterol. Therefore, a statin drug is often prescribed for the duration of the treatment. When the urine is clear of protein, the medications can be discontinued. Fifty percent of patients will relapse and need further treatment with immunosuppressants, such as cyclosporine and tacrolimus.
Minimal change disease usually responds well to initial treatment and over 90% of patients will respond to oral steroids within 6–8 weeks, with most of these having a complete remission. Symptoms of nephrotic syndrome (NS) typically go away; but, this can take from 2 weeks to many months. Younger children, who are more likely to develop minimal change disease, usually respond faster than adults. In 2 out of 3 children with minimal change disease; however, the symptoms of NS can recur, called a relapse, particularly after an infection or an allergic reaction. This is typical and usually requires additional treatment. Many children experience 3 to 4 relapses before the disease starts to go away. Some children require longer term therapy to keep MCD under control. It appears that the more time one goes without a relapse, the better the chances are that a relapse will not occur. In most children with minimal change disease, particularly among those who respond typically, there is minimal to no permanent damage observed in their kidneys.
With corticosteroid treatment, most cases of nephrotic syndrome from minimal change disease in children will go into remission. This typically occurs faster, over 2 to 8 weeks, in younger children, but can take up to 3 or 4 months in adults. Typically, the dose of corticosteroids will initially be fairly high, lasting 1or 2 months. When urine protein levels have normalised, corticosteroids are gradually withdrawn over several weeks (to avoid triggering an Addisonian crisis). Giving corticosteroids initially for a longer period of time is thought to reduce the likelihood of relapse. The majority of children with minimal change disease will respond to this treatment.
Even among those who respond well to corticosteroids initially, it is common to observe periods of relapse (return of nephrotic syndrome symptoms). 80% of those who get minimal change disease have a recurrence. Because of the potential for relapse, the physician may prescribe and teach the patient how to use a tool to have them check urine protein levels at home. Two out of 3 children who initially responded to steroids will experience this at least once. Typically the steroids will be restarted when this occurs, although the total duration of steroid treatment is usually shorter during relapses than it is during the initial treatment of the disease.
There are several immunosuppressive medications that can be added to steroids when the effect is insufficient or can replace them if intolerance or specific contraindications are encountered.
Congenital nephrotic syndrome can be successfully controlled with early diagnosis and aggressive treatment including albumin infusions, nephrectomy, medications and ultimately a kidney transplant. Most children live fairly normal life post-transplant but will spend significant time hospitalised pre-transplant and have numerous surgeries to facilitate treatment.
Due to the protein (albumin) losses many patients have reduced muscle tone and may experience delays in certain physical milestones such as sitting, crawling and walking. Similarly many patients experience growth delays due to protein loss. Delays vary from mild to significant but most patients experience growth spurts once they receive their transplanted kidney. Physical therapy may be useful for the child to strengthen muscle tone.
Undiagnosed cases are often fatal in the first year due to blood clots, infections or other complications.
Available treatments address the symptoms of CCD, not the underlying defect. Early diagnosis and aggressive salt replacement therapy result in normal growth and development, and generally good outcomes. Replacement of NaCl and KCl has been shown to be effective in children.
A potential treatment is butyrate.
Osmotic nephrosis refers to structural changes that occur at the cellular level in the human kidney. Cells, primarily of the straight proximal tubule, swell due to the formation of large vacuoles in the cytoplasm. These vacuoles occur in the presence of large amounts of certain solutes circulating in the tubules. However, despite the condition's name, the solutes do not cause change through osmotic forces but through pinocytosis. Once inside the cytoplasm, pinocytic vacuoles combine with each other and with lysosomes to form large vacuoles that appear transparent under microscopic examination.
There may be no symptomatic presentation with this condition, or it may confused with other nephrotic conditions such as Tubular calcineurin-inhibitor toxicity. Affected cells of the proximal tubule may be passed in the urine, but a kidney biopsy is the only sure way to make a diagnosis.
Responsible exogenous solutes include sucrose-containing IVIg, mannitol, dextran, contrast dye, and hydroxyethyl starch. Prevention includes standard preventions for iatrogenic kidney damage. Osmotic nephrosis is usually reversible but can lead to chronic renal failure.
The long-term use of lithium, a medication commonly used to treat bipolar disorder and schizoaffective disorders, is known to cause nephropathy.
Nephropathy can be associated with some therapies used to treat cancer. The most common form of kidney disease in cancer patients is Acute Kidney Injury (AKI) which can usually be due to volume depletion from vomiting and diarrhea that occur following chemotherapy or occasionally due to kidney toxicities of chemotherapeutic agents. Kidney failure from break down of cancer cells, usually after chemotherapy, is unique to onconephrology. Several chemotherapeutic agents, for example Cisplatin, are associated with acute and chronic kidney injuries. Newer agents such as anti Vascular Endothelial Growth Factor (anti VEGF) are also associated with similar injuries, as well as proteinuria, hypertension and thrombotic microangiopathy.
Treatment of LPI consists of protein-restricted diet and supplementation with oral citrulline. Citrulline is a neutral amino acid that improves the function of the urea cycle and allows sufficient protein intake without hyperammonemia. Under proper dietary control and supplementation, the majority of the LPI patients are able to have a nearly normal life. However, severe complications including pulmonary alveolar proteinosis and renal insufficiency may develop even with proper treatment.
Fertility appears to be normal in women, but mothers with LPI have an increased risk for complications during pregnancy and delivery.
Nephrosis is any of various forms of kidney disease (nephropathy). In an old and broad sense of the term, it is any nephropathy, but in current usage the term is usually restricted to a narrower sense of nephropathy without inflammation or neoplasia, in which sense it is distinguished from nephritis, which involves inflammation. It is also defined as any purely degenerative disease of the renal tubules. Nephrosis is characterized by a set of signs called the nephrotic syndrome. Nephrosis can be a primary disorder or can be secondary to another disorder. Nephrotic complications of another disorder can coexist with nephritic complications. In other words, nephrosis and nephritis can be pathophysiologically contradistinguished, but that does not mean that they cannot occur simultaneously.
Types of nephrosis include amyloid nephrosis and osmotic nephrosis.
In terms of treatment/management for those with Mulibrey nanism should have routine medical follow-ups, additionally the following can be done:
- Growth hormone treatment
- Regular pelvic exams
- Pericardiectomy
There is no cure for Salla disease. Treatment is limited to controlling the symptoms of this disorder. Anti-convulsant medication may control seizure episodes. Physical therapists can assist an affected individual to build muscle strength and coordination.
Minimal change disease has been called by many other names in the medical literature, including minimal change nephropathy, minimal change nephrosis, minimal change nephrotic syndrome, minimal change glomerulopathy, foot process disease (referring to the foot processes of the podocytes), nil disease (referring to the lack of pathologic findings on light microscopy), nil lesions, lipid nephrosis, and lipoid nephrosis.
No treatment is available to cure or slow down the progression of aspartylglucosaminuria. Bone marrow transplants have been conducted in hope that the bone marrow will produce the missing enzyme. The results of the tests thus far have shown to be inconclusive.
Proteinuria is the presence of excess proteins in the urine. In healthy persons, urine contains very little protein; an excess is suggestive of illness. Excess protein in the urine often causes the urine to become foamy, although foamy urine may also be caused by bilirubin in the urine (bilirubinuria), retrograde ejaculation, pneumaturia (air bubbles in the urine) due to a fistula, or drugs such as pyridium.
Since ear infections and respiratory infections are common for children diagnosed with aspartylglucosaminuria, it is best to have regular checkups for both the ears and the respiratory tract.
Extreme sensitivity to the sun’s rays may develop; the best way to protect an individual diagnosed with aspartylglucosaminuria is to have them wear sunglasses, hats or caps to protect their eyes.
Epilepsy and insomnia can both be treated with medication.
It will be beneficial to children who are diagnosed with AGU to receive an education from a school with special teaching.
The infant is intubated post delivery to stabilize the respiratory problems experienced. Often the skin condition becomes less severe resolving itself to flaky dry skin as the individual grows. No intervention is usually required and the condition becomes less severe as the patient grows. The dry skin symptoms can be managed with topical ointments or creams and the individual remains otherwise healthy.
Treatment for Ullrich congenital muscular dystrophy can consist of physical therapy and regular stretching. Respiratory support may be needed at some point by the affected individual.
Though cardiac complications are not a concern in this type of CMD, in regards to respiratory issues ventilation via a tracheostomy is a possibility in some cases.
The preferred treatment of congenital glaucoma is surgical not medical. The initial procedures of choice are goniotomy or trabeculotomy if the cornea is clear, and trabeculectomy ab externo if the cornea is hazy. The success rates are similar for both procedures in patients with clear corneas. Trabeculectomy and shunt procedures should be reserved for those cases in which goniotomy or trabeculotomy has failed. Cyclophotocoagulation is necessary in some intractable cases but should be avoided whenever possible because of its potential adverse
effects on the lens and the retina.
There are no life-threatening complications after the perinatal period (around the time of birth) and the skin conditions persist but to a lesser degree of severity. Individuals have a favourable prognosis as symptoms can be managed and past the infancy stage are not life-threatening. The red skin edema improves after a three-week period but the ichthyosis scaling persists. Asthma has been recorded in some cases later on in the individual's life and sign of atopic dermatitis persist, follicular hyperkeratosis and small amounts of scaling at the scalp that goes on into adulthood but otherwise the individual continues a healthy life.
No cures for lysosomal storage diseases are known, and treatment is mostly symptomatic, although bone marrow transplantation and enzyme replacement therapy (ERT) have been tried with some success. ERT can minimize symptoms and prevent permanent damage to the body. In addition, umbilical cord blood transplantation is being performed at specialized centers for a number of these diseases. In addition, substrate reduction therapy, a method used to decrease the production of storage material, is currently being evaluated for some of these diseases. Furthermore, chaperone therapy, a technique used to stabilize the defective enzymes produced by patients, is being examined for certain of these disorders. The experimental technique of gene therapy may offer cures in the future.
Ambroxol has recently been shown to increase activity of the lysosomal enzyme glucocerebrosidase, so it may be a useful therapeutic agent for both Gaucher disease and Parkinson's disease. Ambroxol triggers the secretion of lysosomes from cells by inducing a pH-dependent calcium release from acidic calcium stores. Hence, relieving the cell from accumulating degradation products is a proposed mechanism by which this drug may help.
Currently, there are no treatments for any of the congenital myopathies. Depending on the severity, there are different therapies available to help alleviate any pain and aid patients in performing varying activities. For example, many congenital myopathy patients are involved in physical or occupational therapy in an attempt to strengthen their skeletal muscles. Orthopedic surgery is usually necessary to correct skeletal deformities secondary to muscle weakness, such as scoliosis. Survival is typically determined by the level of respiratory muscle insufficiency.
Liver transplantation has proven to be effective for ATTR familial amyloidosis due to Val30Met mutation.
Alternatively, a European Medicines Agency approved drug Tafamidis or Vyndaqel now exists which stabilizes transthyretin tetramers comprising wild type and different mutant subunits against amyloidogenesis halting the progression of peripheral neuropathy and autonomic nervous system dysfunction.
Currently there are two ongoing clinical trials undergoing recruitment in the United States and worldwide to evaluate investigational medicines that could possibly treat TTR.
In terms of the management of congenital muscular dystrophy the American Academy of Neurology recommends that the individuals
need to have monitoring of cardiac function, respiratory, and gastrointestinal. Additionally it is believed that therapy in speech, orthopedic and physical areas, would improve the persons quality of life.
While there is currently no cure available, it is important to preserve muscle activity and any available correction of skeletal abnormalities (as scoliosis).Orthopedic procedures, like spinal fusion, maintains/increases the individuals prospect for more physical movement.
The prognosis of this sub-type of MD indicates that the affected individual may eventually have feeding difficulties. Surgery, at some point, might be an option for scoliosis.
Scoliosis which is a sideways curve of the persons vertebrate, is determined by a variety of factors, including the degree (mild or severe), in which case if possible a brace might be used by the individual
