HIV/ AIDS Flashcards
IMMUNODEFICIENCY DISORDERS
PRIMARY
- GENETIC
- MAY AFFECT PHAGOCYTIC FUNCTION, B CELLS OR T CELLS, OR THE COMPLEMENT SYSTEM
SECONDARY MORE COMMON THAN PRIMARY
- ACQUIRED
- HIV/AIDS
- RELATED TO UNDERLYING DISORDERS, DISEASES, TOXIC SUBSTANCES, OR MEDICATIONS
ACQUIRED IMMUNEDEFICIENCY SYNDROME (AIDS)
- HUMAN IMMUNE DEFICIENCY VIRUS (HIV) CAN PROGRESS TO AIDS
- MOST COMMON IMMUNE DEFICIENCY DISEASE IN THE WORLD
- SERIOUS WORLDWIDE EPIDEMIC
HEALTH PROMOTION AND MAINTENANCE
HIV USUALLY TRANSMITTED VIA:
- SEXUAL CONTACT
- PARENTERALLY
- PERINATALLY
HIV IS NOT TRANSMITTED:
- CASUALLY
- BY SHARING HOUSEHOLD UTENSILS, TOWELS, LINENS, TOILETS
- VIA MOSQUITOES OR INSECTS
TRANSMISSION OF HIV
Transmitted in body fluids of:
- BLOOD SEMINAL FLUID
- VAGINAL SECRETIONS
- AMNIOTIC FLUID
- BREAST MILK THAT CONTAIN INFECTED CELLS
risk associated with HIV infection
- Sharing infected injection drug use equipment
- Having sexual relations with infected individuals
- Infants born to mothers with HIV infection and/or who are breast-fed by HIV infected mothers
- People who received organ transplants, HIV infected blood, or blood products
Sexual transmission
- Gender transmission
- Sexual acts
- Viral load
CDC DESCRIBES ABCS OF SAFER SEX:
- A β ABSTINENCE
- B β BE FAITHFUL
- C β CONDOM USE
- TEACH SAFE SEX
PARENTERAL TRANSMISSION
- PROPER CLEANING OF βWORKSβ
β NEEDLES AND SYRINGES (clean with bleach/ water)
β OTHER DRUG PARAPHERNALIA - NEEDLE EXCHANGE PROGRAMS
BLOOD TRANSFUSION TRANSMISSION
- RISK FOR TRANSMISSION BY BLOOD TRANSFUSION REDUCED TO A NATIONAL AVERAGE OF 0.02%.
- ALL DONATED BLOOD SCREENED
- TIME LAG BETWEEN ANTIBODY PRODUCTION POST EXPOSURE CAN CAUSE FALSE NEGATIVE.
PERINATAL TRANSMISSION
- ACROSS THE PLACENTA DURING PREGNANCY
- INFANT EXPOSURE AT BIRTH TO BLOOD AND VAGINAL SECRETIONS
- EXPOSURE AFTER BIRTH THROUGH BREAST MILK
WOMEN AND HIV
- 25% OF NEW CASES
- CAUSE IS SEXUAL EXPOSURE
- POORER OUTCOMES THAN MEN
β more apt to get opportunistic diseases and late DX - GYNECOLOGIC PROBLEMS ARE USUALLY FIRST SIGN
GENETIC CONSIDERATIONS
- NON PROGRESSORS
- 1% OF THOSE WITH HIV
- ASYMPTOMATIC
- SOME MAY NOT NEED MEDS
HIV AND THE ELDERLY
- 50 YEAR OR GREATER
- EARLY MORTALITY AND MORBIDITY
- MOST PROGRAMS FOCUS ON YOUNGER AGE GROUPS
- ASSESS FOR RISKY BEHAVIORS
- DECREASED IMMUNITY
- less likely to get tested
HEALTH PROMOTION AND MAINTENANCE
- Teach everyone about transmission routes, and ways to reduce exposure.
- Teach all people regardless age, gender, ethnicity, or sexual orientation
Protecting Against HIV Infection All patients should be advised to:
- Abstain from exchanging sexual fluids (semen and vaginal fluid)
- Reduce the number of sexual partners to one
- Always use latex condoms. *If the patient is allergic to latex, nonlatex condoms should be used; however, they will not protect against HIV infection.
- Not reuse condoms
- Avoid using cervical caps or diaphragms without using a condom as well
- Always use dental dams for oralβgenital or anal stimulation.
- Avoid anal intercourse, because this practice may injure tissues; if not possible, use lubricantβthere are water and silicone-based products designed for anal sex.
- Avoid manualβanal intercourse (βfistingβ).
- Avoid sharing needles, razors, toothbrushes, sex toys, or blood- contaminated articles.
- Consider PrEP if regularly engage in high-risk behaviors.
Protecting Against HIV Infection (Continued)
Patients who are HIV seropositive should also be advised to:
- *Take ART regularly to achieve viral suppression. antiretroviral therapy
- PrEP, pre-exposure prophylaxis.
- Inform previous, present, and prospective sexual and drug-using partners of their HIV-positive status.
- If the patient is concerned for their safety, advise the patient that many states have established mechanisms through the public health department in which professionals are available to notify exposed contacts.
- Avoid having unprotected sex with another HIV-seropositive person. Cross-infection with that personβs HIV can increase the severity of infection.
- Do Not donate blood, plasma, body organs, or sperm.
PRE EXPOSURE PROPHYLAXIS (PrEP)
- NEW RESEARCH
- COMBO DRUG TRUVADA
β (EMTRICITABINE AND TENOFOVIR) - DOES NOT REPLACE SAFER SEX BUT IS USED
- TO TREAT AND PREVENT TRANSMISSION
TRANSMISSION AND HEALTH CARE WORKERS
- NEEDLE STICK (βSHARPSβ) INJURIES
- EXPOSURE OF NONINTACT SKIN/MUCOUS MEMBRANES TO BLOOD AND BODY FLUIDS
- STANDARD PRECAUTIONS IS BEST PREVENTION
- POST-EXPOSURE PROPHYLAXIS (PEP)
- SEE CHART 19-1 RECOMMENDATIONS FOR PREVENTING HIV TRANSMISSION BY HCW
Outside
- Shell has special docking features that assist in finding a host.
Inside
- Genetic material and enzymes.
LIFE CYCLE OF HIV
STEP 1-8
- ATTACHMENT/BINDING
- UNCOATING/FUSION
- DNA SYNTHESIS
- INTEGRATION
- TRANSCRIPTION
- TRANSLATION
- CLEAVAGE BUDDING
HIV CLASSIFICATION
COLLABORATIVE MANAGEMENT
- ASSESSMENT; ask pt if ok to speak in front oft of family
- HISTORY
- PHYSICAL ASSESSMENT/CLINICAL
- MANIFESTATIONS:
β INFECTIONS β OPPORTUNISTIC, PROTOZOAL, FUNGAL, BACTERIAL, VIRAL
β MALIGNANCIES β KAPOSIβS SARCOMA (KS), MALIGNANT LYMPHOMAS, INVASIVE CANCERS, HPV
β ENDOCRINE COMPLICATIONS - PSYCHOSOCIAL ASSESSMENT β SUPPORT SYSTEMS, CONFIDENTIALITY
