Hyperviscosity Syndrome (High Level of Plasma Proteins in the Blood) in Dogs
- Occurrence: rarer
- Location of illness: General/Whole body
Hyperviscosity syndrome in dogs is characterized by increased blood viscosity, usually due to a high level of plasma proteins. This thickening of the blood impairs normal blood flow and can lead to a variety of clinical problems.
The most important facts at a glance
Hyperviscosity syndrome in dogs is a condition in which the blood becomes thicker due to a high level of plasma proteins, especially immunoglobulins. This increased viscosity can impair blood flow and lead to various health problems. The main cause is often an excessive production of antibodies by diseases such as lymphomas or plasmacytomas. Chronic Inflammatory conditions and infections can also increase plasma protein levels.
Typical symptoms include loss of appetite, weakness, increased thirst and urination, Tendency to bleed, and breathing problems. In severe cases, Seizures, nosebleeds, and vision problems can occur. Blood tests are performed to diagnose the condition and check the protein concentration, as well as imaging procedures to detect Tumors or organ enlargements.
Treatment focuses on combating the underlying disease, often through surgery, radiation therapy, or chemotherapy. In acute cases, plasmapheresis may be necessary to remove excess proteins. Medications such as corticosteroids can also be used to reduce Inflammatory conditions and modulate the immune response.
The prognosis depends on the underlying cause. If the underlying disease is treated successfully, blood viscosity can normalize. There are no direct preventive measures, but regular veterinary check-ups and a healthy lifestyle can help minimize risks. Research focuses on developing new diagnostic and treatment methods as well as understanding the causes of this disease.
Causes
Blood viscosity refers to the thickness and stickiness of the blood, which is crucial for smooth blood flow through the vessels. In dogs affected by Hyperviscosity Syndrome, this viscosity is increased, often due to excessive production of plasma proteins such as immunoglobulins. These proteins can accumulate in the blood for various reasons.
One of the main causes of Hyperviscosity Syndrome is the excessive production of antibodies, often associated with certain cancers such as lymphomas or plasmacytomas. These conditions lead to an abnormally high number of plasma cells that produce large amounts of antibodies, which increase blood viscosity.
In addition, chronic Inflammatory conditions and infections can also lead to an increase in plasma proteins. Infections that heavily tax the immune system can stimulate excessive protein production to protect the body, which in turn increases blood viscosity.

The symptoms of Hyperviscosity Syndrome in dogs can vary widely and often depend on the underlying cause and the degree of viscosity increase. The most common signs include Lethargy and weakness, caused by reduced oxygen supply to the tissues.
Other symptoms may include neurological problems such as Seizures or Behavioral changes, which result from insufficient blood flow to the brain. Nosebleeds or Bleeding gums are also common, as the increased viscosity can lead to vascular damage.
Additionally, there may be enlargement of the lymph nodes or spleen. These symptoms are often the result of the underlying condition causing the Hyperviscosity Syndrome, such as lymphoma.
Diagnosis
Diagnosis of Hyperviscosity Syndrome typically begins with a thorough clinical examination and a detailed history of the dog. The veterinarian will look for specific symptoms and consider the animal’s medical history to identify potential causes.
A complete blood count and serum chemistry are crucial to measure the concentration of plasma proteins and assess blood viscosity. Elevated protein levels, especially immunoglobulins, may indicate the presence of Hyperviscosity Syndrome.
In addition, imaging techniques such as X-rays or ultrasounds can be used to identify possible Tumors or enlargements of organs such as the spleen or lymph nodes. In some cases, a bone marrow examination may be necessary to confirm the presence of abnormal plasma cells.
Therapy
Treatment for Hyperviscosity Syndrome aims to address the underlying cause and alleviate symptoms. If a Tumor is the cause, surgery, radiation therapy, or chemotherapy may be considered to reduce the Tumor mass and decrease plasma protein production.
Plasmapheresis can be used in acute cases to remove excess proteins from the blood and rapidly reduce viscosity. This technique can be life-saving, especially in dogs with severe neurological symptoms.
Additionally, medications such as corticosteroids can be used to reduce Inflammatory conditions and modulate the immune response. These medications help reduce plasma protein production and normalize blood viscosity.
Prognosis and follow-up care
The prognosis for dogs with Hyperviscosity Syndrome depends heavily on the underlying cause. With successful treatment of the underlying disease, such as Tumor removal, blood viscosity can normalize and the dog can live a normal life.
However, if the underlying condition is chronic or incurable, as may be the case with some cancers, the prognosis is often more guarded. The dog’s quality of life can be improved through symptomatic treatment and management, but the long-term prognosis depends on the specific disease and its Aggressiveness.
Prevention
Since Hyperviscosity Syndrome is often associated with cancers and chronic Inflammatory conditions, there are no specific preventive measures that can completely prevent the syndrome. However, regular veterinary check-ups are crucial to detect and treat potential problems early.
A balanced diet and a healthy lifestyle can strengthen the immune system and reduce the risk of infections and chronic Inflammatory conditions. In addition, it is important to minimize known risk factors for cancers by paying attention to environmental toxins and harmful substances.
Owners should watch for changes in their dog’s behavior or health and consult a veterinarian for unusual symptoms to diagnose and treat potential conditions early.
Outlook on current research
Hyperviscosity Syndrome in dogs is a complex condition characterized by a high level of plasma proteins in the blood. This increase in proteins can increase the viscosity or thickness of the blood, leading to a number of health challenges. Current research focuses on understanding the exact mechanisms that lead to this condition, as well as developing new diagnostic and treatment methods.
A significant part of the research is the investigation of the causes for the increased production of plasma proteins. Genetic factors play a role here, but also environmental factors and the presence of certain diseases, such as Tumors of the immune system, which can lead to an increase in immunoglobulins. Researchers are also investigating how Hyperviscosity Syndrome interacts with other diseases and what role it plays in the worsening of symptoms.
Another area of research focuses on optimizing diagnostic tests. Traditionally, the diagnosis is made through blood tests that measure the viscosity of the blood and determine the protein content. However, new technological advances enable more accurate and faster diagnoses that are less invasive and allow for faster treatment.
In therapy development, new drugs and treatment approaches are currently being tested that can reduce plasma protein production or alleviate the symptoms of the syndrome. These new approaches aim to improve the quality of life of affected dogs and optimize the prognosis.
In the long term, researchers hope to create a more comprehensive understanding base that will make it possible to develop preventive measures. These could help reduce the risk of developing Hyperviscosity Syndrome or mitigate its course before it leads to serious health problems.
