There is as yet inadeqaute data from randomised controlled trials.
Treatment with HAART and ACE inhibitors/Angiotensin receptor blockers has been shown to be beneficial and should be given to all patients unless otherwise contra-indicated. General renoprotective measures and the treatment of the complications of nephrotic syndrome and kidney failure are adjunctive.
Corticosteroid treatment can be useful in patients who do not respond to the above treatment. There is some evidence that ciclosporin might be helpful in selective cases, however further trials are required on both steroids and ciclosporin before these drugs can become standardised treatment if at all.
Perhaps the most difficult aspect of membranous glomerulonephritis is deciding which people to treat with immunosuppressive therapy as opposed to simple "background" or anti-proteinuric therapies. A large part of this difficulty is due to a lack of ability to predict which people will progress to end-stage renal disease, or renal disease severe enough to require dialysis. Because the above medications carry risk, treatment should not be initiated without careful consideration as to risk/benefit profile. Of note, corticosteroids (typically Prednisone) alone are of little benefit. They should be combined with one of the other 5 medications, each of which, along with prednisone, has shown some benefit in slowing down progression of membranous nephropathy. It must be kept in mind, however, that each of the 5 medications also carry their own risks, on top of prednisone.
The twin aims of treating membranous nephropathy are first to induce a remission of the nephrotic syndrome and second to prevent the development of endstage renal failure. A meta-analysis of four randomized controlled studies comparing treatments of membranous nephropathy showed that regimes comprising chlorambucil or cyclophosphamide, either alone or with steroids, were more effective than symptomatic treatment or treatment with steroids alone in inducing remission of the nephrotic syndrome.
The disease can be treated only to slow down the development, by use of cyclosporine A and ACE inhibitors, but not stopped or cured.
Treatment of secondary membranous nephropathy is guided by the treatment of the original disease. For treatment of idiopathic membranous nephropathy, the treatment options include immunosuppressive drugs and non-specific anti-proteinuric measures. Recommended first line therapy often includes: cyclophosphamide alternating with a corticosteroid.
Studies on the treatment of cryofibrinoginemic disease have involved relatively few patients, are limited primarily to case reports, and differ based on whether the disease is primary or secondary. In all cases of cryofibrinogenemic disease, however, patients should avoid the exposure of afflicted body parts to cold weather or other environmental triggers of symptoms and avoid using cigarettes or other tobacco products. In severe cases, these individuals also risk developing serious thrombotic events which lead to tissue necrosis that may result in secondary bacterial infections and require intensive antimicrobial therapy and/or amputations. Careful treatment of these developments is required.
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.
Treatment of secondary cryofibrinoginemic disease may use the same methods used for treating the primary disease wherever necessary but focus on treating the associated infectious, malignant, premalignant, vasculitis, or autoimmune disorder with the methods prescribed for the associated disorder. Case report studies suggest that: corticosteroids and immunosuppressive drug regimens, antimicrobial therapy, and anti-neoplastic regimens can be effective treatments for controlling the cryfibrinoginemic disease in cases associated respectively with autoimmune, infectious, and premalignant/malignant disorders.
The treatment of kidney damage may reverse or delay the progression of the disease. Kidney damage is treated by prescribing drugs:
- Corticosteroids: the result is a decrease in the proteinuria and the risk of infection as well as a resolution of the edema. Prednisone is usually prescribed at a dose of 60 mg/m² of body surface area/day in a first treatment for 4–8 weeks. After this period the dose is reduced to 40 mg/m² for a further 4 weeks. Patients suffering a relapse or children are treated with prednisolone 2 mg/kg/day till urine becomes negative for protein. Then, 1.5 mg/kg/day for 4 weeks. Frequent relapses treated by: cyclophosphamide or nitrogen mustard or cyclosporin or levamisole. Patients can respond to prednisone in a number of different ways:
- Corticosteroid sensitive patient or early steroid-responder: the subject responds to the corticosteroids in the first 8 weeks of treatment. This is demonstrated by a strong diuresis and the disappearance of edemas, and also by a negative test for proteinuria in three urine samples taken during the night.
- Corticosteroid resistant patient or late steroid-responder: the proteinuria persists after the 8-week treatment. The lack of response is indicative of the seriousness of the glomerular damage, which could develop into chronic kidney failure.
- Corticosteroid tolerant patient: complications such as hypertension appear, patients gain a lot of weight and can develop aseptic or avascular necrosis of the hip or knee, cataracts and thrombotic phenomena and/or embolisms.
- Corticosteroid dependent patient: proteinuria appears when the dose of corticosteroid is decreased or there is a relapse in the first two weeks after treatment is completed.
The susceptibility testing in vitro to glucocorticoids on patient's peripheral blood mononuclear cells is associated with the incidence of not optimal clinical responses: the most sensitive patients in vitro have shown a higher incidence of corticodependence, while the most resistant patients in vitro showed a higher incidence of ineffective therapy.
- Immunosupressors (cyclophosphamide): only indicated in recurring nephrotic syndrome in corticosteroid dependent or intolerant patients. In the first two cases the proteinuria has to be negated before treatment with the immunosuppressor can begin, which involves a prolonged treatment with prednisone. The negation of the proteinuria indicates the exact moment when treatment with cyclophosphamide can begin. The treatment is continued for 8 weeks at a dose of 3 mg/kg/day, the immunosuppression is halted after this period. In order to be able to start this treatment the patient should not be suffering from neutropenia nor anaemia, which would cause further complications. A possible side effect of the cyclophosphamide is alopecia. Complete blood count tests are carried out during the treatment in order to give advance warning of a possible infection.
The objective of this treatment is to treat the imbalances brought about by the illness: edema, hypoalbuminemia, hyperlipemia, hypercoagulability and infectious complications.
- Edema: a return to an unswollen state is the prime objective of this treatment of nephrotic syndrome. It is carried out through the combination of a number of recommendations:
- Rest: depending on the seriousness of the edema and taking into account the risk of thrombosis caused by prolonged bed rest.
- Medical nutrition therapy: based on a diet with the correct energy intake and balance of proteins that will be used in synthesis processes and not as a source of calories. A total of 35 kcal/kg body weight/day is normally recommended. This diet should also comply with two more requirements: the first is to not consume more than 1 g of protein/kg body weight/ day, as a greater amount could increase the degree of proteinuria and cause a negative nitrogen balance. Patients are usually recommended lean cuts of meat, fish, and poultry. The second guideline requires that the amount of water ingested is not greater than the level of diuresis. In order to facilitate this the consumption of salt must also be controlled, as this contributes to water retention. It is advisable to restrict the ingestion of sodium to 1 or 2 g/day, which means that salt cannot be used in cooking and salty foods should also be avoided. Foods high in sodium include seasoning blends (garlic salt, Adobo, season salt, etc.) canned soups, canned vegetables containing salt, luncheon meats including turkey, ham, bologna, and salami, prepared foods, fast foods, soy sauce, ketchup, and salad dressings. On food labels, compare milligrams of sodium to calories per serving. Sodium should be less than or equal to calories per serving.
- Medication: The pharmacological treatment of edema is based on the prescription of diuretic drugs (especially loop diuretics, such as furosemide). In severe cases of edema (or in cases with physiological repercussions, such as scrotal, preputial or urethral edema) or in patients with one of a number of severe infections (such as sepsis or pleural effusion), the diuretics can be administered intravenously. This occurs where the risk from plasmatic expansion is considered greater than the risk of severe hypovolemia, which can be caused by the strong diuretic action of intravenous treatment. The procedure is the following:
- Hypoalbuminemia: is treated using the medical nutrition therapy described as a treatment for edema. It includes a moderate intake of foods rich in animal proteins.
- Hyperlipidaemia: depending of the seriousness of the condition it can be treated with medical nutrition therapy as the only treatment or combined with drug therapy. The ingestion of cholesterol should be less than 300 mg/day, which will require a switch to foods that are low in saturated fats. Avoid saturated fats such as butter, cheese, fried foods, fatty cuts of red meat, egg yolks, and poultry skin. Increase unsaturated fat intake, including olive oil, canola oil, peanut butter, avocadoes, fish and nuts. In cases of severe hyperlipidaemia that are unresponsive to nutrition therapy the use of hypolipidemic drugs, may be necessary (these include statins, fibrates and resinous sequesters of bile acids).
- Thrombophilia: low molecular weight heparin (LMWH) may be appropriate for use as a prophylactic in some circumstances, such as in asymptomatic patients that have no history of suffering from thromboembolism. When the thrombophilia is such that it leads to the formation of blood clots, heparin is given for at least 5 days along with oral anticoagulants (OAC). During this time and if the prothrombin time is within its therapeutic range (between 2 and 3), it may be possible to suspend the LMWH while maintaining the OACs for at least 6 months.
- Infectious complications: an appropriate course of antibacterial drugs can be taken according to the infectious agent.
In addition to these key imbalances, vitamin D and calcium are also taken orally in case the alteration of vitamin D causes a severe hypocalcaemia, this treatment has the goal of restoring physiological levels of calcium in the patient.
- Achieving better blood glucose level control if the patient is diabetic.
- Blood pressure control. ACE inhibitors are the drug of choice. Independent of their blood pressure lowering effect, they have been shown to decrease protein loss.
Management of sickle nephropathy is not separate from that of overall patient management. In addition, however, the use of ACE inhibitors has been associated with improvement of the hyperfiltration glomerulopathy. Three-year graft and patient survival in kidney transplant recipients with sickle nephropathy is lower when compared to those with other causes of end-stage kidney disease.
Although plasma exchange/infusion (PE/PI) is frequently used, there are no controlled trials of its safety or efficacy in aHUS. Even though PE/PI often partially controls some of the hematological manifestations of aHUS in some patients, its effectiveness has not been demonstrated in terms of inducing total disease remission. PE/PI is associated with significant safety risks, including risk of infection, allergic reactions, thrombosis, loss of vascular access, and poor quality of life. Importantly, terminal complement activation has been shown to be chronically present on the surface of platelets in patients with aHUS who appear to be clinically well while receiving chronic PE/PI.
Before the introduction of eculizumab (INN and USAN, trade name Soliris), a monoclonal antibody that is a first-in-class terminal complement inhibitor, management options for patients with aHUS were extremely limited. Guidelines issued by the European Paediatric Study Group for HUS recommend rapid administration of plasma exchange or plasma infusion (PE/PI), intensively administered daily for 5 days and then with reducing frequency. However, the American Society for Apheresis offers a "weak" recommendation for plasma exchange to treat aHUS, due to the "low" or "very low" quality of evidence supporting its use. Although some patients experienced improvements in red blood cell and platelet counts, plasma therapies generally did not result in full remission.
The best treatment is prevention in patients with a known predisposition. This includes preventing unnecessary trauma or surgery (including ear piercing, elective mole removal), whenever possible. Any skin problems in predisposed individuals (e.g., acne, infections) should be treated as early as possible to minimize areas of inflammation.
Treatment of a keloid scar is age dependent. Radiotherapy, anti-metabolites and corticoids would not be recommended to be used in children, in order to avoid harmful side effects, like growth abnormalities.
In adults, corticosteriods combined with 5-FU and PDL in a triple therapy, enhance results and diminish side effects.
Further prophylactic and therapeutic strategies include pressure therapy, silicone gel sheeting, intra-lesional triamcinolone acetonide (TAC), cryosurgery, radiation, laser therapy, IFN, 5-FU and surgical excision as well as a multitude of extracts and topical agents.
Surgical excision is currently still the most common treatment for a significant amount of keloid lesions. However, when used as the solitary form of treatment there is a large recurrence rate of between 70 and 100%. It has also been known to cause a larger lesion formation on recurrence. While not always successful alone, surgical excision when combined with other therapies dramatically decreases the recurrence rate. Examples of these therapies include but are not limited to radiation therapy, pressure therapy and laser ablation. Pressure therapy following surgical excision has shown promising results, especially in keloids of the ear and earlobe. The mechanism of how exactly pressure therapy works is unknown at present but many patients with keloid scars and lesions have benefited from it.
Should keloids occur, the most effective treatment is superficial external beam radiotherapy (SRT), which can achieve cure rates of up to 90%.
Additionally, intralesional injection with a corticosteroid such as Kenalog does appear to aid in the reduction of inflammation and pruritus.
Cryotherapy or cryosurgery is an application of extreme cold to treat keloids. This treatment method is easy to perform and has shown results with least chance of recurrence.
Therapy involves both preventive measures and treatment of specific bleeding episodes.
- Dental hygiene lessens gingival bleeding
- Avoidance of antiplatelet agents such as aspirin and other anti-inflammatory drugs (NSAIDs) such as ibuprofen and naproxen, and anticoagulants
- Iron or folate supplementation may be necessary if excessive or prolonged bleeding has caused anemia
- Hepatitis B vaccine
- Antifibrinolytic drugs such as tranexamic acid or ε-aminocaproic acid (Amicar)
- Desmopressin (DDAVP) does not normalize the bleeding time in Glanzmann's thrombasthenia but anecdotally improves hemostasis
- Hormonal contraceptives to control excessive menstrual bleeding
- Topical agents such as gelfoam, fibrin sealants, polyethylene glycol polymers, custom dental splints
- Platelet transfusions (only if bleeding is severe; risk of platelet alloimmunization)
- Recombinant factor VIIa, AryoSeven or NovoSeven FDA approved this drug for the treatment of the disease on July 2014.
- Hematopoietic stem cell transplantation (HSCT) for severe recurrent hemorrhages
Focal segmental glomerulosclerosis (FSGS) is a cause of nephrotic syndrome in children and adolescents, as well as a leading cause of kidney failure in adults. It is also known as "focal glomerular sclerosis" or "focal nodular glomerulosclerosis". It accounts for about a sixth of the cases of nephrotic syndrome. (Minimal change disease (MCD) is by far the most common cause of nephrotic syndrome in children: MCD and primary FSGS may have a similar cause.)
Membranoproliferative glomerulonephritis ("MPGN"), also known as mesangiocapillary glomerulonephritis, is a type of glomerulonephritis caused by deposits in the kidney glomerular mesangium and basement membrane (GBM) thickening, activating complement and damaging the glomeruli.
MPGN accounts for approximately 4% of primary renal causes of nephrotic syndrome in children and 7% in adults.
It should not be confused with membranous glomerulonephritis, a condition in which the basement membrane is thickened, but the mesangium is not.
In children and some adults, FSGS presents as a nephrotic syndrome, which is characterized by edema (associated with weight gain), hypoalbuminemia (low serum albumin, a protein in the blood), hyperlipidemia and hypertension (high blood pressure). In adults, it may also present as kidney failure and proteinuria, without a full-blown nephrotic syndrome.
Transplant glomerulopathy, abbreviated TG, is a disease of the glomeruli in transplanted kidneys. It is a type of renal injury often associated with chronic antibody-mediated rejection. However, transplant glomerulopathy is not specific for chronic antibody-mediated rejection; it may be the result of a number of disease processes affecting the glomerular endothelium.
Several treatments are available, and successful control of the disease is common.
Not everyone needs treatment immediately. Treatment is usually given when the symptoms of the disease interfere with the patient's everyday life, or when white blood cell or platelet counts decline to dangerously low levels, such as an absolute neutrophil count below one thousand cells per microliter (1.0 K/uL). Not all patients need treatment immediately upon diagnosis.
Treatment delays are less important than in solid tumors. Unlike most cancers, treatment success does not depend on treating the disease at an early stage. Because delays do not affect treatment success, there are no standards for how quickly a patient should receive treatment. However, waiting too long can cause its own problems, such as an infection that might have been avoided by proper treatment to restore immune system function. Also, having a higher number of hairy cells at the time of treatment can make certain side effects somewhat worse, as some side effects are primarily caused by the body's natural response to the dying hairy cells. This can result in the hospitalization of a patient whose treatment would otherwise be carried out entirely at the hematologist's office.
Single-drug treatment is typical. Unlike most cancers, only one drug is normally given to a patient at a time. While monotherapy is normal, combination therapy—typically using one first-line therapy and one second-line therapy—is being studied in current clinical trials and is used more frequently for refractory cases. Combining rituximab with cladribine or pentostatin may or may not produce any practical benefit to the patient. Combination therapy is almost never used with a new patient. Because the success rates with purine analog monotherapy are already so high, the additional benefit from immediate treatment with a second drug in a treatment-naïve patient is assumed to be very low. For example, one round of either cladribine or pentostatin gives the median first-time patient a decade-long remission; the addition of rituximab, which gives the median patient only three or four years, might provide no additional value for this easily treated patient. In a more difficult case, however, the benefit from the first drug may be substantially reduced and therefore a combination may provide some benefit.
HIV-associated nephropathy (HIVAN) refers to kidney disease developing in association with HIV infection. The most common, or "classical", type of HIV-associated nephropathy is a collapsing focal segmental glomerulosclerosis (FSGS), though other forms of kidney disease may also occur with HIV. Regardless of the underlying histology, renal disease in HIV-positive patients is associated with an increased risk of death.
HIVAN may be caused by direct infection of the renal cells with the HIV-1 virus, with resulting renal damage through the viral gene products. It could also be caused by changes in the release of cytokines during HIV infection. Usually occurs only in advanced disease and approximately 80% of patients with HIVAN have a CD4 count of less than 200. HIVAN presents with nephrotic syndrome and progressive kidney failure. Despite being a cause of chronic kidney failure, kidney sizes are usually normal or large.
Cladribine (2CDA) and pentostatin (DCF) are the two most common first-line therapies. They both belong to a class of medications called purine analogs, which have mild side effects compared to traditional chemotherapy regimens.
Cladribine can be administered by injection under the skin, by infusion over a couple of hours into a vein, or by a pump worn by the patient that provides a slow drip into a vein, 24 hours a day for 7 days. Most patients receive cladribine by IV infusion once a day for five to seven days, but more patients are being given the option of taking this drug once a week for six weeks. The different dosing schedules used with cladribine are approximately equally effective and equally safe.
Relatively few patients have significant side effects other than fatigue and a high fever caused by the cancer cells dying, although complications like infection and acute kidney failure have been seen.
Pentostatin is chemically similar to cladribine, and has a similar success rate and side effect profile, but it is always given over a much longer period of time, usually one dose by IV infusion every two weeks for three to six months.
During the weeks following treatment the patient's immune system is severely weakened, but their bone marrow will begin to produce normal blood cells again. Treatment often results in long-term remission. About 85% of patients achieve a complete response from treatment with either cladribine or pentostatin, and another 10% receive some benefit from these drugs, although there is no permanent cure for this disease. If the cancer cells return, the treatment may be repeated and should again result in remission, although the odds of success decline with repeated treatment. Remission lengths vary significantly, from one year to more than twenty years. The median patient can expect a treatment-free interval of about ten years.
It does not seem to matter which drug a patient receives. A patient who is not successfully treated with one of these two drugs has a reduced chance of being successfully treated with the other. However, there are other options.
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.
Asymptomatic individuals with intracranial stenosis are typically told to take over the counter platelet inhibitors like aspirin whereas those with symptomatic presentation are prescribed anti-coagulation medications. For asymptomatic persons the idea is to stop the buildup of plaque from continuing. They are not experiencing symptoms; however if more build up occurs it is likely they will. For symptomatic individuals it is necessary to try and reduce the amount of stenosis. The anti-coagulation medications reduce the likelihood of further buildup while also trying to break down the current build up on the surface without an embolism forming. For those with severe stenosis that are at risk for impending stroke endovascular treatment is used. Depending on the individual and the location of the stenosis there are multiple treatments that can be undertaken. These include angioplasty, stent insertion, or bypass the blocked area.
The first step in treating Reinke’s edema is to eliminate or control those risk factors that are causing the disease. This includes the cessation of smoking, the control of gastric reflux using antacids and/or Proton Pump Inhibitors (PPIs), and the discontinuation of activities that cause vocal distress. Those experiencing a hoarseness of the voice may choose to undergo voice therapy to improve the voice’s quality and range. Most cases of Reinke’s edema are caused by the long term usage of cigarettes. In this case, it is important to make lifestyle changes to stop smoking. While this will not resolve or improve the edema, the cessation of smoking will halt the disease's progression.
If the elimination of risk factors is not sufficient to improve the patient’s symptoms, surgery may be required. The most common type of surgery performed today for Reinke's edema is called surgical microlaryngoscopy. Most procedures follow the microflap technique set in place by Hirano. During surgery, an incision is made into the vocal cord using either microscissors or a CO laser. A flap of mucosa is lifted and the affected tissue is removed using suction or a microdebrider. The flap is then re-draped and trimmed to the appropriate size.
Most cases of Reinke’s Edema are bilateral - effecting both vocal cords - rather than unilateral. In the case of bilateral edema, the surgeon must choose whether to operate each side of the vocal cord in two separate surgeries or to operate both sides in a single surgery. The complication associated with removing tissue from both sides in a single surgery is that the raw, cut ends of the vocal cords may form an anterior glottis web, in which the two sides grow together in a continuous sheet. Other complications of surgery include tissue scarring due to damage to the vocal ligament during the incision and vocal cord stiffening due to over-suctioning of the superficial lamina propria (Reinke’s space).
While surgical microlarynscopy has its associated risks, if left untreated, Reinke’s edema can lead to a variety of long-term complications. Besides dysphonia (impaired speech), the most serious of these complications is airway obstruction due to severe inflammation of the vocal cords. The risk of complications has decreased drastically with the creation of new tools, such as the CO laser for surgical microlaryngoscopy. Before the Hirano microflap method was developed in 1895, vocal stripping was the most common procedure used to correct Reinke's Edema. Vocal stripping was often performed without magnification and with a monocular laryngoscope, instead of a binocular scope. This led to major complications such as vocal ligament scarring.
Women are more likely than men to undergo surgery due to a greater change in vocal pitch and quality. Surgery is capable of restoring the voice, with the condition that smoking is not resumed after surgery. Post-operative voice therapy is also advised to restore the voice's strength. Reinke's edema is not a fatal pathology unless the tissue becomes precancerous.
Affected male and carrier female dogs generally begin to show signs of the disease at two to three months of age, with proteinuria. By three to four months of age, symptoms include for affected male dogs: bodily wasting and loss of weight, proteinuria & hypoalbuminemia. Past nine months of age, hypercholesterolemia may be seen. In the final stages of the disease, at around 15 months of age for affected males, symptoms are reported as being renal failure, hearing loss and death. Since the condition is genetically dominant, diagnosis would also include analysis of the health of the sire and dam of the suspected affected progeny if available.
