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. 3 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 4 Natural History of HIV Infection Without the Use of Antiretroviral Tx 1200 Primary Infection 1100 Death Opportunistic Diseases 1000 106 Clinical latency 900 CD4 + T Lymphocyte Count (cells/mmm3) 107 800 Constitutional Symptoms 700 105 600 104 500 400 300 103 200 100 102 0 0• 3• 6• 9• 12 Weeks 1• 2• 3• 4 5• 6• 7• 8 9• 10• 11 Years Source: Fauci, A., Pantaleo, D., Stanley S., Weismann, D.

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 9 HIV test and counseling 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 13 性病之診斷分類及治療 性病之分類 • • • • • 尿道炎及子宮頸炎 陰部潰瘍 鼠蹊淋巴腫 陰部新生物 全身性感染 男性尿道炎 • 症狀 – 分泌物、小便疼痛、尿道口癢 • 病原菌 – – – – – Neisseria gonorrhoeae Chlamydia trachomatis Ureaplasma urealyticum ?
