Acquired Immunodeficiency Syndrome, also known as AIDS, is a transmissible infection caused by the Human Immunodeficiency Virus (HIV), which can be treated with antiretroviral therapy, immunomodulation and opportunistic infections. 1. Antiviral therapy: “Cocktail” mixed therapy, i.e. highly effective combined antiretroviral therapy, using protease inhibitors and reverse transcriptase inhibitors. Commonly used drugs include zidovudine, lamivudine, efavirenz, lopinavir, ritonavir and so on. 2. Immunomodulation: use recombinant human interferon α2a, recombinant human interleukin-2, intravenous input of human immunoglobulin and other drugs to regulate the immune function and enhance the body’s immune ability. 3. Treatment of opportunistic infections: common infections include Pneumocystis carinii infection, cryptosporidiosis, tuberculosis, respiratory tract infections, etc., which need to be treated with appropriate sensitive drugs for the pathogenic microorganisms. It is recommended that patients consult a doctor in time for early treatment and use medication under the guidance of a doctor.
