2 Human Immunodeficiency Virus/ Acquired Immunodeficiency Syndrome
HIV/AIDS Human Immunodeficiency Virus/ Acquired Immunodeficiency Syndrome

3 What Is HIV/AIDS? Acquired immunodeficiency syndrome (AIDS) is caused by the human immunodeficiency virus (HIV). HIV attacks and destroys white blood cells, causing a defect in the body’s immune system. The immune system of an HIV-infected person becomes so weakened that it cannot protect itself from serious infections. When this happens, the person clinically has AIDS. AIDS may manifest as early as 2 years or as late as 10 years after infection with HIV.

4 Clinical Spectrum of AIDS
Group 1: Acute infection 0-3 weeks Window period: Seroconversion 3-12 weeks Group 2: Asymptomatic infection 0-10 years Group 3: Persistent generalized LAP Group 4: Other HIV-related diseases Constitutional diseases Neurological disorders Opportunistic infections Secondary neoplasms Other conditions

6 Signs and Symptoms of AIDS
Fever of unknown origin Enlarged lymph glands Skin rashes and cough Persistent diarrhea Severe weight loss Skin lesions Loss of appetite and fatigue

9 Diagnosis of HIV Mainly serological
Through antibody testing with ELISA; if positive, confirmation by Western Blot Culture of blood and tissues RT-PCR：mainly for follow up

12 HIV test and counseling

13 Treatment of HIV Infected Patients
At present, no drug or therapy can cure AIDS Availability of anti-AIDS vaccines appears unlikely in the near future A combination of three antiretrovirals (ARVs) is the gold standard for treatment ARVs are not universally available, are very expensive and must be administered correctly

25 尿道炎治療後症狀 若治療後，尿道炎症狀持續，該怎麼辦： 追出性伴侶，並給予治療 重新確認尿道炎的存在 若無尿道炎存在，只需加強病人信心即可
若仍有尿道炎存在，可給予metronidazole 2 gm PO stat 慢性攝護腺炎 (不可能)

26 陰道分泌物之鑑別診斷 白帶 (bacterial vaginosis) 念珠菌陰道炎 (Candida vaginitis)
