Causes
Feline coronaviruses are widespread and relatively harmless in their original form. They mainly infect the intestinalIntestinal refers to the intestine, the part of the digestive tract that extends from the stomach to the anus. Intestinal diseases affect the small and/or large intestine. lining of cats and can cause mild cases of DiarrheaDiarrhea refers to the condition of frequent, watery bowel movements, which can be a sign of infections, digestive disorders, or other health problems. that often go unnoticed. These harmless coronaviruses are common in many cat populations, especially in multi-cat households and catteries.

There are two main forms of FIP: the wet (effusive) and the dry (non-effusive) form. The wet form is characterized by fluid accumulation in body cavities such as the abdomenThe abdomen, also known as the abdominal cavity, is the part of the body located between the rib cage and the pelvis. It houses several important organs, including the stomach, liver, kidneys, intestines, and spleen. or chest, while the dry form causes granulomatous Inflammatory conditions in various organs. Both forms are difficult to diagnose and often lead to Death.
Symptoms
Symptoms of FIP vary depending on the form of the disease and the organs affected. In the wet form, fluid accumulation in the abdominalThe term “abdominal” refers to anything that concerns the belly or the abdomen. It is an adjectival expression used to describe the location, symptoms, or conditions that occur in the abdominal area. cavity (ascitesAscites refers to the accumulation of free fluid in the abdominal cavity, which can lead to visible abdominal distension. It can be caused by various diseases, including liver disease, cancer, or heart failure.) or chest cavity (pleural effusion) is typically the main feature. These can lead to RespiratoryRespiratory refers to breathing or the process of breathing. Respiratory diseases affect the respiratory tract and can impair the ability to breathe effectively. distress, abdominalThe term “abdominal” refers to anything that concerns the belly or the abdomen. It is an adjectival expression used to describe the location, symptoms, or conditions that occur in the abdominal area. enlargement, and discomfort.
The dry form of FIP tends to cause non-specific symptoms such as chronic Fever, Weight loss, loss of appetite, lethargy, and neurological signs like Convulsions or coordination problems. Eye changes such as uveitis can also occur.
Because the symptoms are so diverse and can also occur with other diseases, FIP is a difficult condition to diagnose. Often, the symptoms are more general in nature and develop gradually, which further complicates the diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients..
Diagnosis
The diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. of FIP is complex and often a diagnosis of exclusionA diagnosis of exclusion is a method where other potential causes of a patient's symptoms are systematically ruled out until the most likely cause remains. In dogs and cats, this method is often used for complex or unclear clinical pictures.. The first step is a thorough clinical examination, followed by blood tests that can indicate an inflammatory markerInflammatory markers are substances in the blood that increase in concentration when there are inflammatory conditions in the body. They help with the diagnosis and monitoring of inflammatory conditions in dogs and cats., anemia, or elevated globulin levels. Specific tests for coronavirus antibodies are available, but they cannot distinguish between the harmless and the mutated form.
In the case of the wet form, analyzing the accumulated fluid in the abdomen or chest can provide clues for an FIP diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients.. This fluid is often straw-yellow, viscous, and high in proteinProteins are large molecules made up of amino acids and play an essential role in almost all biological processes. They are necessary for building body tissue, the function of the immune system, and as enzymes for metabolic reactions.. A definitive diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests.

Since there is no simple test that can definitively confirm FIP, the diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. is often based on a combination of clinical findings, laboratory results, and the exclusion of other diseases.
Therapy
Until recently, FIP was considered incurable, but newer research approaches have produced promising treatments. Traditionally, FIP therapyTherapy refers to the treatment of diseases or disorders with the aim of alleviating symptoms, promoting healing, or improving quality of life. Therapies can be medicinal, surgical, or through other medical interventions. was limited to alleviating symptoms and supporting the immune systemThe immune system is the body's defense system against infectious agents such as bacteria, viruses, fungi, and parasites. It comprises a complex network of organs, cells, and molecules that work together to protect the body., often using steroidsSteroids are a group of lipids that include both hormones and certain medications. In veterinary medicine, steroids are used to treat inflammatory conditions, allergies, and autoimmune diseases in dogs and cats. and other anti-inflammatory drugsAnti-inflammatory drugs are medications that reduce inflammation. They can be divided into nonsteroidal anti-inflammatory drugs (NSAIDs) and corticosteroids and are used in dogs and cats to reduce Inflammatory conditions and Pain..
More recently, antiviral drugs such as GS-441524, a nucleoside analog, have been developed, which have led to disease remission in some cases. However, this treatment is expensive, not officially approved, and its long-term efficacy is still the subject of studies.
Since the therapyTherapy refers to the treatment of diseases or disorders with the aim of alleviating symptoms, promoting healing, or improving quality of life. Therapies can be medicinal, surgical, or through other medical interventions. is complex and intensive, it should always be accompanied by a veterinarian who has experience with FIP. TherapyTherapy refers to the treatment of diseases or disorders with the aim of alleviating symptoms, promoting healing, or improving quality of life. Therapies can be medicinal, surgical, or through other medical interventions. can take weeks to months and requires close monitoring of the cat’s health status.
Prognosis and follow-up care
The prognosis for cats with FIP was very poor for a long time, as the disease was almost always fatal. With new treatment approaches, however, the outlook for some cats has improved. There are reports of cats that have gone into remission and been able to lead a normal life after treatment with antiviral drugs.
The prognosisThe prognosis is the prediction of the likely course and outcome of a disease based on the general state of health, the nature of the disease, and the response to treatment. It can provide information on how a disease is expected to develop. depends heavily on the form of FIP (wet or dry), the affected organ, and the timing of the diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients.. Early detection and treatment can increase the chances of survival, but the disease remains a serious threat to the lives of affected cats.

Outlook on current research
Feline Infectious Peritonitis (FIP) is a fatal viral infection in cats caused by the Feline Coronavirus (FCoV). Current research is focused on understanding the mechanisms by which the harmless Feline Enteric Coronavirus (FECV) undergoes a mutation into the deadly FIP virusA virus is a microscopic infectious particle that cannot reproduce on its own and must infect a host cell to produce new virus particles. Viruses can cause a variety of diseases in humans, animals, and plants.. This mutationA mutation is a permanent change in the DNA sequence (genetic material) of an organism. In dogs and cats, mutations can lead to genetic diseases or desirable changes in certain traits. occurs in only a small percentage of infected cats, making the study of genetic, immunological, and virological factors that favor this transformation particularly important.
A significant focus of current research is the development of new diagnostic tests. Since there is currently no specific and reliable method to clearly provide a diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. for FIP in living cats, scientists are working on molecular biology techniques that could help detect the disease at an early stage. The use of advanced imaging techniques and biomarkers is also being investigated to increase diagnostic accuracy.
Furthermore, intensive work is being done on the development of vaccines against FIP. While some experimental vaccines already exist, their effectiveness has been insufficient so far. The challenge is to generate an immune responseAn immune response is the immune system's reaction to foreign substances (antigens), such as microorganisms or proteins. It involves a series of processes aimed at recognizing, fighting, and eliminating these antigens. strong enough to prevent the disease without inducing immunopathology. To this end, novel approaches are being pursued, including the use of vectorA vector is an organism that can transmit pathogens from one host to another without contracting the disease itself, such as ticks, fleas, and mosquitoes. vaccines and genetically modified viruses.
Another significant area of research is the development of antiviral therapies. Some promising approaches involve the use of protease inhibitors and nucleoside analog therapies that target the virusA virus is a microscopic infectious particle that cannot reproduce on its own and must infect a host cell to produce new virus particles. Viruses can cause a variety of diseases in humans, animals, and plants. directly to prevent its replication. InitialInitial means beginning or at the start. In medicine, it can refer to the first symptoms of a disease or the first phase of a treatment process. studies in cats show positive results, but further investigations are necessary to confirm the safety and efficacy of these forms of therapyTherapy refers to the treatment of diseases or disorders with the aim of alleviating symptoms, promoting healing, or improving quality of life. Therapies can be medicinal, surgical, or through other medical interventions..
In addition to virological and immunological aspects, the genetic predispositionA predisposition is an innate inclination or susceptibility of an organism to certain diseases or conditions. In dogs and cats, there may be a genetic predisposition to certain conditions such as hip dysplasia or certain heart diseases. of cats that could lead to FIP development is also being investigated. In the long term, this research could help develop breeding programs that reduce the risk of FIP. Genome-wide association studies are used to identify possible genetic markers that correlate with an increased susceptibility to the disease.
Collaboration between universities, research institutions, and pharmaceutical companies is crucial to accelerate progress in FIP research. By combining resources and expertise, researchers hope to provide more effective diagnostic methods, vaccines, and treatments in the near future to significantly improve the prognosisThe prognosis is the prediction of the likely course and outcome of a disease based on the general state of health, the nature of the disease, and the response to treatment. It can provide information on how a disease is expected to develop. for cats with FIP.
