Hypertrophic gastritis in dogs: A comprehensive analysis

Hypertrophic gastritis is one of the lesser-known, yet serious diseases in dogs that can have a significant impact on the health and quality of life of our pets.

Definition and introduction of hypertrophic gastritis in dogs

Hypertrophic gastritis is a specific form of chronic gastritis in dogs, characterized by significant thickening of the gastric mucosa and the formation of pronounced rugae. It is a rare disease, the etiology of which is often unclear, but in some cases can be attributed to prolonged inflammation, interstitial edema, and cystic glandular formations.

Rugae hyperplasia – what is it?

Rugae hyperplasia refers to an increased formation of cell tissue in the gastric folds (rugae) and is a characteristic feature of hypertrophic gastritis in dogs. This section provides a more detailed explanation of rugae hyperplasia in dogs with hypertrophic gastritis.

What are Rugae?

The rugae are folds in the stomach wall that allow the stomach to expand and contract. They play a crucial role in the mechanics of digestion, as they aid the movement and mixing of stomach contents.

Hyperplasia of the rugae

In rugae hyperplasia, the cell tissue in these folds proliferates. This leads to a thickening of the stomach wall and can impair normal stomach function. The hyperplasia can be distributed throughout the entire stomach or limited to specific areas, such as the pyloric antrum or the pylorus.

Effects on the dog

Hyperplasia of the rugae can cause various symptoms and complications in dogs. The thickening of the stomach wall can disrupt normal gastric emptying and restrict stomach motility. In severe cases, this can lead to vomiting, weight loss, anemia, and other health problems.

Causes and treatment

Hyperplasia of the rugae can be caused by chronic inflammation, tumors, and other pathological conditions. The exact causes of hypertrophic gastritis and the associated hyperplasia of the rugae are often unclear and can be varied.

The treatment of rugae hyperplasia primarily aims to address the underlying cause and alleviate symptoms. This may include medication, surgery, or dietary adjustments, depending on the severity and extent of the condition. In any case, early diagnosis and individualized treatment are crucial to ensure the animal's well-being.

Etiology of hypertrophic gastritis in dogs

The causes of hypertrophic gastritis are varied and can be of a very different nature:

• Chronic inflammation and uremiaThese can lead to the development of the disease in the long term.
• HypergastrinemiaProlonged disturbances in stomach acid production and elevated stomach pH can lead to increased gastrin production, which secondarily triggers hypertrophic gastritis.
• Tumor-induced gastritisTumors, especially pancreatic tumors and mast cell tumors, can cause hypertrophic gastritis by producing gastrin-like substances.

Clinical signs and symptoms of hypertrophic gastritis in dogs

The symptoms are often subtle and can be confused with other forms of chronic gastritis. These include:

• Vomiting
• weight loss
• Hypoalbuminemia
• anemia

In advanced cases, gastric emptying disorders, gastric dilatation, and morphological pyloric stenosis may occur.

Diagnostics and differential diagnoses of hypertrophic gastritis in dogs

An accurate diagnosis is essential and requires a thorough examination. Differential diagnoses include stomach tumors and other forms of chronic gastritis. Various diagnostic methods, such as ultrasound and endoscopy, are helpful in establishing a correct diagnosis.

Detailed explanation of the diagnosis of hypertrophic gastritis in dogs

To diagnose hypertrophic gastritis in dogs and differentiate it from other gastrointestinal diseases, a series of diagnostic procedures and tests must be performed. The diagnostic process should be systematic and comprehensive to obtain an accurate picture of the disease and ensure the best possible treatment.

1. Clinical examination of hypertrophic gastritis in dogs

First, the veterinarian conducts a thorough clinical examination, taking the animal's medical history and assessing its overall condition. This can provide clues to possible causes and the severity of the illness.

2. Blood test

A complete blood count and biochemical profile are important to identify inflammation, anemia, and other disorders that may be associated with hypertrophic gastritis. Additionally, gastrin levels in the blood can be measured to detect hypergastrinemia.

3. Urine analysis

A urinalysis can help to rule out or confirm kidney dysfunction and uremia, which can lead to hypertrophic gastritis.

4. Imaging Techniques

• Ultrasound examinationThis allows visualization of the stomach wall and can reveal changes such as thickenings or tumors.
• X-ray imagesThey can help identify obstructions, enlargements, and other abnormalities of the stomach.
• EndoscopyThis offers the possibility to directly view the mucous membrane of the stomach and allows biopsies to be taken for further examination.

5. Biopsy and histopathology

Tissue samples (biopsies) of the stomach, collected during an endoscopy, are examined microscopically to determine the type of cell changes, the extent of inflammation, and the presence of tumors.

6. Bacteriological examination

A culture of the gastric mucosa can be performed to determine the presence of bacterial infections that may be contributing to gastritis.

Diploma

After a thorough medical history, clinical examination, and performance of the diagnostic tests mentioned above, the veterinarian can make a diagnosis and create an appropriate treatment plan. Early diagnosis and treatment are crucial to prevent the progression of the disease and improve the dog's quality of life.

Therapeutic measures – hypertrophic gastritis in dogs

Treatment primarily focuses on addressing the underlying disease and providing symptom-based relief. In many cases, dietary modifications and, if necessary, immunosuppressants such as prednisolone are indicated. If pyloric stenosis is present, surgical intervention is often required to remove obstructing mucosal folds.

Detailed explanation of treatment options for hypertrophic gastritis in dogs

The treatment of hypertrophic gastritis in dogs depends largely on the underlying cause of the disease and can therefore vary. The focus is on alleviating symptoms and, if possible, addressing the root cause.

Dietary measures

An important part of the treatment is adjusting the dog's diet. A special diet containing easily digestible proteins and carbohydrates is often necessary. Low-fat, high-fiber, and hypoallergenic diets can help alleviate symptoms and protect the gastrointestinal tract.

Drug therapy

In many cases, medication may be necessary to control and treat the symptoms. This includes:

• ImmunosuppressantsPrednisolone can be administered in certain doses to reduce inflammation. Dosage should be according to veterinary recommendations and the manufacturer's information.
• ProkineticsMedications such as metoclopramide can help with gastric emptying disorders by accelerating gastric emptying.
• Antibiotics: If a bacterial infection is confirmed, the use of antibiotics may be necessary.

Small calculator for determining the correct amount of prednisolone

This calculator is only a guideline – the final amount and medication will be determined by your individual needs. Veterinarian!

This example uses a dosage of 0.5 mg prednisolone per kg of body weight. Please note that the dosage must be determined individually by a veterinarian based on the severity of the illness and the animal's overall health. It is important to strictly adhere to the dosage and duration of treatment as prescribed by the veterinarian to avoid side effects and complications.

Surgical interventions

If pyloric stenosis is present, surgical intervention is often unavoidable. This involves removing obstructing mucosal folds and/or performing a pyloroplasty to facilitate the drainage of stomach contents.

There are several surgical approaches to treating pyloric stenosis. The most common is laparoscopy, in which small incisions are made to insert an endoscope and open the pylorus. Another option is open surgery, which involves a larger incision to gain direct access to the pylorus. The choice of procedure depends on the severity of the stenosis and the individual needs of the patient. After surgery, careful monitoring and follow-up care are essential to prevent complications and support the healing process.

Supportive therapy

Additionally, supportive therapies such as fluid therapy and nutritional therapy may be necessary, especially if the dog is severely dehydrated or requires nutritional support.

Preventive measures

Although hypertrophic gastritis is often triggered by internal factors, preventive measures such as a balanced diet, regular veterinary check-ups and avoiding stress can help reduce the risk of developing the disease.

Important information about medication

It is important to emphasize that the manufacturer's information must be followed when administering medication and that the dosage instructions should not be exceeded in order to ensure the animal's safety.
