    Study Notes

    Human Immunodeficiency Virus Infection

    • HIV infection leads to a range of clinical manifestations, with HIV-1 more common in the U.S. than HIV-2.
    • Acquired Immunodeficiency Syndrome (AIDS) is an advanced stage of HIV infection, categorized by specific criteria in children, adolescents, and adults.
    • Acute retroviral syndrome (in 50-90% of infected adults and adolescents) appears during the initial weeks, characterized by nonspecific symptoms like fever, malaise, lymphadenopathy, and rash.
    • Early symptoms in untreated children include unexplained fevers, lymphadenopathy, enlarged liver and spleen, failure to thrive, recurring oral thrush, diarrhea, parotitis (inflammation of the salivary glands), and hepatitis, CNS issues (e.g., encephalopathy, hyperreflexia, hypertonia, floppiness, developmental delays), lymphoid interstitial pneumonia, and recurring infections.
    • Timely diagnosis and treatment reduce the occurrence of AIDS-defining illnesses in children and adolescents in developed countries.
    • In the era of combination antiretroviral therapy (cART), there's been a substantial decrease in opportunistic infections (OIs).
    • Immune reconstitution inflammatory syndrome (IRIS) is a paradoxical deterioration observed shortly after starting cART, due to inflammation as the immune system recovers.

    HIV Infection in Adolescents

    • HIV infection in adolescents is primarily transmitted through sexual activity, followed by injection drug use.
    • In 2014, males in the 13-24 age group primarily acquired HIV through male-to-male sexual contact.
    • In 2010, there were approximately 40,144 adolescents (13-24 years old) living with HIV in the U.S. and associated territories.
    • A large proportion of adolescents with HIV infection are undiagnosed.
    • Most adolescents with HIV infection are asymptomatic, and unaware of infection at diagnosis.

    HIV Incubation Period

    • Untreated infants and children typically show symptoms 12-18 months after infection, while some present earlier or remain asymptomatic for several years.
    • Early presentation of symptoms can occur, but a bimodal distribution generally follows, with rapid progressors dying before age four, and slower progressors remaining asymptomatic for years.

    Diagnostic Tests for HIV

    • Serologic assays (including antigen/antibody combination immunoassays and antibody differentiation assays) are used.
    • Nucleic acid amplification assays (e.g., HIV-1 DNA/RNA assays) can detect HIV infection and measure viral load.

    Treatment and Prevention of HIV

    • Combination antiretroviral therapy (cART) is standard treatment, aimed at suppressing viral load and restoring immune function.
    • Antiretroviral prophylaxis (ARV) is crucial during pregnancy to prevent mother-to-child transmission (MTCT).
    • Cesarean delivery before labor and before rupture of membranes, and avoidance of breastfeeding are important strategies to prevent transmission.
    • Vaccination strategies are consistent with recommendations for the general population, however considerations for specific situations must be made.
    • Opportunistic infections, like Pneumocystis jirovecii pneumonia (PCP), should be addressed with prophylaxis in accordance with the CD4+ T-lymphocyte count, viral load, and other medical factors.
