ANA index and HIV
I had an ANA test at the Rheumatology and Immunology Department of Taoyuan Hospital, Ministry of Health and Welfare, with a result of 1:1280.
All detailed examinations were normal, but I am experiencing pain in my left knee and finger joints, as well as dry mouth and dry eyes.
The doctor has currently prescribed Belimumab and Pain Stop tablets for 28 days, one tablet per day.
My question is about the relationship between the ANA index and HIV.
After having sexual relations with a sex worker on May 1, I experienced symptoms of urethritis, which was cured after a week of antibiotics.
However, I am concerned whether the elevated ANA index is related to HIV.

Dear readers:
Regarding the question of whether a high ANA index is related to HIV, the response is as follows.
[Interferents and Unrelated Health Conditions] An assessment of the impact of interferents and unrelated health conditions on the specificity of this assay was conducted by testing 321 serum/plasma specimens from individuals with various health conditions unrelated to HIV-1 infection, as well as 119 specimens with added interferents.
The results are shown in Table 10.
Among the specimens that yielded false-positive results, one specimen was positive for Epstein-Barr virus (EBV), hepatitis B virus (HBV), and rheumatoid factor, while another came from a multiparous woman.
Additionally, three specimens from individuals infected with hepatitis A virus (HAV) also showed false positives.
Furthermore, an evaluation of the effect of anticoagulants on specificity was performed by collecting venous whole blood from 24 HIV-negative subjects.
The specimens were treated with three types of anticoagulants (EDTA, sodium heparin, and sodium citrate) and stored under refrigeration (2–8°C), at room temperature (18°C), or in a temperature gradient (30–33°C) for more than 7 days.
Specimens stored at 2–30°C for 5 days did not exhibit any anticoagulant-specific effects, as detailed in Table 10.

The connection between Antinuclear Antibody (ANA) levels and HIV risk is a complex topic that requires a nuanced understanding of both immunology and infectious diseases. ANA is a type of antibody that the immune system produces, which can indicate autoimmune disorders when present at elevated levels. A high ANA titer, such as 1:1280, can suggest the presence of autoimmune conditions like lupus, rheumatoid arthritis, or Sjögren's syndrome, especially when accompanied by symptoms like joint pain and dryness of the eyes and mouth, as you described.
However, it is important to clarify that elevated ANA levels are not directly indicative of HIV infection or risk. HIV (Human Immunodeficiency Virus) primarily affects the immune system by targeting CD4 T cells, leading to a progressive decline in immune function if left untreated. While individuals with HIV may exhibit various immune system abnormalities, including the production of autoantibodies, a high ANA level alone does not imply that one is at risk for HIV.
Your concern about the relationship between your recent sexual encounter and the elevated ANA levels is understandable, especially given the context of your symptoms and the history of urethritis. It is crucial to note that while certain infections can trigger autoimmune responses, the presence of ANA does not confirm or rule out an HIV infection. The symptoms you experienced after your encounter, such as urethritis, could be due to a sexually transmitted infection (STI) or other causes unrelated to HIV.
To assess your risk for HIV, it is essential to consider factors such as the nature of the sexual encounter, the use of protection, and the HIV status of your partner. If you have concerns about potential HIV exposure, the best course of action is to undergo HIV testing. Testing is the only definitive way to determine your HIV status, and it is recommended to do so at least 2-4 weeks after potential exposure for accurate results.
Regarding your current treatment with medications like Belimumab (likely what you meant by "必賴克瘻") and pain relief medications, these are typically used to manage autoimmune conditions and may help alleviate your symptoms. It is essential to follow your doctor's recommendations and monitor your symptoms closely. If you experience any new or worsening symptoms, or if you have ongoing concerns about your health, do not hesitate to reach out to your healthcare provider.
In summary, while elevated ANA levels can indicate an autoimmune process, they do not have a direct correlation with HIV risk. It is crucial to address your concerns through appropriate testing and consultation with your healthcare provider, who can provide tailored advice based on your specific health situation. Regular follow-ups and open communication with your doctor will help ensure that both your autoimmune symptoms and any potential infectious risks are managed effectively.
