  3. 3. Human Immunodeficiency Virus • Nurses: Largest group of healthcare workers to occupationally acquire HIV • 2007 Deaths: 2.1 million people (decline) • U.S. Health Problem – African-Americans: HIV infection rate 8 times higher than whites – 2003 • 2nd leading death cause in African-American males, ages 35-44 • 3rd leading death cause in African-American females, ages 35-44 Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins

  7. 7. HIV Replication; Transmission ● Transmission: Body fluids − Blood − Semen − Vaginal secretions − Breast milk ● Specific behaviors increase risk Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
  8. 8. Human Immunodeficiency Virus • Pathophysiology and Etiology – Infected CD4 cells are unable to recognize foreign antigens – Viral cells continue parasitic replication, resulting in decreased CD4 cell count • >10 billion viral particles released daily • Frequent mutations complicate drug therapy • Render vaccine development virtually impossible • New strains Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
  9. 9. Human Immunodeficiency Virus • Prevention Strategies – Prevention guideline compliance • No sex with strangers; Mutually monogamous sex – uninfected partner • Use condoms effectively • No IV, psychostimulant drug use – Use standard precautions – Immediately report needlesticks • Get prophylactic treatment Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
  10. 10. Acquired Immunodeficiency Syndrome • Is End Stage HIV Infection – Immunodeficiency develops – Mortality from opportunistic infection; Cancers • Progression Related to – Viral concentration in blood – Subtype, strain of infecting HIV – CD4 cell status • Few Long-term Survivors Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins

Medical Management • Antiretroviral Drug Therapy – Initiation controversy; Very expensive – Reverse transcriptase inhibitors • NRTIs + NNRTIs: Cripple viral copying • Nucleotide analogues: Activate immediately on entering CD4 cell – Protease inhibitors: Interfere with viral copy maturation – Entry inhibitors: Block proteins or surface coreceptors of the CD4 T-cell lymphocyte • HAART Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins

  16. 16. Medical Management • Adjunct Drug Therapy – Hydroxyurea: Interferes with viral replication – IL-2: Boosts immune defenses against HIV • AIDS Vaccines: In clinical trials; Success unlikely due to frequent viral mutations • Drug resistance development due to noncompliance – Medication compliance difficult • Numerous medications taken simultaneously ATC requiring near-perfect compliance • Undesirable GI side effects Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
