Life Cycle of HIV-1
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Stages of HIV Disease
• Primary infection
• HIV asymptomatic
• HIV symptomatic
• AIDS
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Primary Infection
• AKA acute HIV infection/acute HIV syndrome
• Part of CDC category A
• Symptoms: none to flu-like syndrome
• Window period: lack of HIV antibodies
• Period of rapid viral replication and dissemination
through the body
• Viral set point: balance between amount of HIV and the
immune response
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
HIV Asymptomatic
• CDC category A
• More than 500 CD4+ T lymphpocytes/mm3
• Upon reaching the viral set point, chronic asymptomatic
state begins
• Body has sufficient immune response to defend against
pathogens
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
HIV Symptomatic
• CDC category B
• 200–499 CD4+ lymphpocytes/mm3
• CD4 T cells gradually fall
• The patient develops symptoms or conditions related to
the HIV infection, which are not classified as category C
conditions
• Patients who are once treated for a category B condition
are considered category B
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
AIDS
• CDC category C
• Less than 200 CD4+ lymphocytes/mm3
• As levels drop below 100 cell/mm3 the immune system is
significantly impaired
• Development of listed conditions
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Treatment
• Treatment and protocols are continually evolving
• Antiretroviral agents
– Nucleoside reverse transcriptase inhibitors (NRTIs)
– Non-nucleoside reverse transcriptase inhibitors (NNRTIs)
– Protease inhibitors (PIs)
– Fusion inhibitors
– Use of combination therapy
• Management also focuses upon the treatment of specific
manifestations and conditions related to the disease
