Autoimmune diseases


Hello Doctor, last year I had a health check-up due to my studies, and since I was on my menstrual period that day, I experienced hematuria.
After returning to the hospital for a follow-up, it was confirmed that there were no issues, and the cause of the hematuria was indeed contamination from menstrual blood.
However, the hospital conducted blood tests, and the results indicated that I have an autoimmune disease.
I am uncertain whether I actually have an autoimmune disease, and the nephrologist advised me to return to the rheumatology and immunology department for a follow-up in six months.
They instructed me to maintain my usual lifestyle, avoid excessive fatigue, and refrain from consuming anything that would boost my immune system.
The test results showed the following values in red: PT: 13.2, Glo: 2.5, C3: 57.7, C4: 10.7, ANA: Dense fine speckled, with a titer of 1:160.

Hello, thank you for your message.
The following test results may be related to autoimmune diseases, and if necessary, further blood tests can be arranged: C3: 57.7, C4: 10.7, ANA: Dense fine speckled with a titer of 1:160.
I'm not sure if your physician has already arranged for further blood tests.
If not, and you are concerned, I suggest that you prepare your test reports and visit the Allergy, Immunology, and Rheumatology department for consultation.
Changhua Hospital, Ministry of Health and Welfare is here to support you.

Understanding autoimmune diseases is crucial for anyone experiencing symptoms or receiving a diagnosis related to these conditions. Autoimmune diseases occur when the immune system mistakenly attacks the body's own tissues, leading to inflammation and damage. This can affect various organs and systems, resulting in a wide range of symptoms.

In your case, the presence of blood in your urine was determined to be due to menstrual contamination, which is a common occurrence and typically not a cause for concern. However, the blood tests you underwent revealed some abnormalities that prompted your healthcare provider to suggest the possibility of an autoimmune disease. The specific results you mentioned include:
- PT (Prothrombin Time): 13.2 seconds - This is a measure of how long it takes for blood to clot. While this value is important, it is not directly indicative of autoimmune disease.

- Glo (Globulin): 2.5 g/dL - This protein level can indicate various conditions, including autoimmune diseases, but must be interpreted in the context of other tests.

- C3: 57.7 mg/dL and C4: 10.7 mg/dL - These are complement proteins that play a role in the immune response. Low levels can be associated with autoimmune diseases, particularly lupus.

- ANA (Antinuclear Antibody): Dense fine speckled, 1:160 - This test is often used to screen for autoimmune diseases. A positive result can indicate the presence of an autoimmune disorder, but it is not definitive on its own.

The recommendation to follow up with a rheumatologist is appropriate, as they specialize in autoimmune diseases and can provide a more comprehensive evaluation. They may conduct further testing to clarify your diagnosis and determine the best course of action.

It's also important to note that autoimmune diseases can manifest in various ways, and symptoms can range from mild to severe. Common autoimmune diseases include rheumatoid arthritis, lupus, multiple sclerosis, and type 1 diabetes, among others. Each condition has its own set of symptoms and treatment protocols.

Regarding your question about lifestyle modifications, it is generally advisable for individuals with autoimmune diseases to maintain a balanced diet, manage stress, and engage in regular physical activity, as these factors can influence overall health and potentially mitigate symptoms. However, the idea of avoiding foods that "boost the immune system" can be misleading. Instead, focusing on a well-rounded diet rich in fruits, vegetables, whole grains, and lean proteins is beneficial.
In conclusion, while autoimmune diseases can be complex and multifaceted, understanding your specific condition and working closely with your healthcare providers is essential. They can help you navigate the challenges of living with an autoimmune disease, including managing symptoms and making informed lifestyle choices. If you have further questions or concerns, don't hesitate to reach out to your healthcare team for personalized advice and support.
