Cyclosporine (Modified)

Cyclosporine is a vital treatment in veterinary medicine for dogs, primarily addressing immune-mediated ailments and allergic reactions. Cyclosporine is commonly prescribed to manage conditions like atopic dermatitis, characterized by itching and skin irritation due to environmental allergens. Cyclosporine is also effective in treating immune-mediated diseases like polyarthritis and inflammatory bowel disease. It is beneficial for certain autoimmune disorders where the immune system mistakenly attacks the body's own tissues. Additionally, cyclosporine aids in boosting tear production for dogs with dry eye conditions (keratoconjunctivitis sicca).

Cyclosporine does not belong to the category of steroids. It's an immunosuppressive medication that works differently from steroids. Steroids like prednisone or cortisone work by reducing inflammation through diverse mechanisms. In contrast, cyclosporine operates by suppressing the immune system's response, primarily by inhibiting the activation of specific immune cells, particularly T lymphocytes.

One of the major adverse effects of cyclosporine is its potential to cause nephrotoxicity, which refers to kidney damage or impairment. Prolonged use of cyclosporine can lead to renal dysfunction, affecting the kidneys' ability to filter waste products and maintain proper fluid balance. Regular blood tests are essential for individuals taking cyclosporine to monitor kidney function and mitigate the risk of nephrotoxicity. Adjusting the dosage as needed based on these tests helps minimize the potential adverse effect on the kidneys.

Andie Lenhard, a specialized DVM and RN from Southeastern Appalachia, highlights the multifaceted origins of dermatitis in dogs. It can arise from flea allergies, other allergic reactions, fungal or bacterial infections, and may even be associated with specific cancers or hormonal imbalances. Each root cause requires a unique and tailored treatment method. Lenhard strongly cautions against trying unproven remedies proposed by untrained sources and strongly recommends seeking professional veterinary advice. This approach ensures targeting the precise underlying causes of the condition, preventing unnecessary expenditure on ineffective medications and supplements.

Dermatitis in dogs, especially atopic dermatitis (allergic skin inflammation), is often managed rather than completely cured. The goal of treatment is to control and alleviate the symptoms, reduce flare-ups, and improve the dog's quality of life. Treatment typically involves identifying and minimizing exposure to allergens and managing secondary infections. It often includes using antihistamines, steroids, immunosuppressive drugs such as cyclosporine, and medicated shampoos to control itching and inflammation. In some cases, allergy testing and allergen-specific immunotherapy may be considered to desensitize the dog's immune system to specific allergens.

For dogs with atopic dermatitis, choosing an appropriate diet often involves exploring options like limited ingredient diets (LID) or novel protein diets. These diets aim to identify and manage potential food allergies or sensitivities associated with the condition. They often feature a single protein source or novel proteins like duck, venison, or unique fish to minimize allergic reactions. Hydrolyzed protein diets can also be beneficial to break down proteins into smaller components. Including omega-3 fatty acids from fish oil or fish-rich diets supports healthy skin and reduces inflammation. Avoiding potential trigger ingredients such as certain grains, soy, or specific proteins like beef or chicken might also be necessary.

For dogs with skin allergies, it's often recommended to avoid potential trigger ingredients that can exacerbate allergic reactions. Common food allergens in dogs include wheat, corn, soy, dairy products, beef, chicken, and certain artificial additives or preservatives. These ingredients may contribute to skin irritation and allergic responses. Additionally, avoiding table scraps and human foods with high salt or fat content is advisable for dogs with skin allergies. Opting for a balanced, hypoallergenic commercial dog food can be beneficial in managing their condition effectively.

Michael Hoover, a former veterinarian from Manchester, advises bathing your dog 1-2 times weekly with a medicated shampoo for skin needs. This routine helps address skin issues effectively and maintain the dog's cleanliness. However, if an over-the-counter (OTC) shampoo is used, Hoover recommends limiting baths to once a week. He advises that bathing every two weeks would be a preferable option when using OTC shampoos to prevent potential skin irritation or drying.

Eggs can potentially contribute to improving a dog's skin health due to their nutritional content. They are a good source of protein, vitamins, and essential fatty acids, particularly omega-3 fatty acids, which can support healthy skin and a shiny coat. Omega-3 fatty acids have anti-inflammatory properties that may help alleviate itching and reduce skin inflammation associated with conditions like atopic dermatitis.
