Remains a disease of?
Marginalized individuals (those who are disenfranchised by virtue of gender, race, sexual orientation, poverty, drug use, or lack of access to health care)
AIDS has killed....... people throughout the world and ..........are infected
>20 million/>60 million
It's projected that the number of deaths caused by AIDS in the next 10 years will?
Be greater that the combines fatalities in all wars of the 20th century
HIV is a fragile virus that can only be transmitted under specific conditions that allow contact with infected body fluids, including???
Blood, Semen, Vaginal fluids, Brest Milk
Infection occur after an exposure depends on ?
1. Duration and frequency of contact, 2. Volume of fluid in exposure, 3. Virulence (The ability of any agent of infection to produce diseas) and the concentration of the organism, 4. Host immune defense capability.
Once the person is infected, they have a LIFELONG ability to?
Transmit HIV to others (Few days post infection to death: HIV infected individuals can transmit HIV to others)
When are the large amounts in the blood?
2-6 days (most initial infection), and During late stages of the disease...........VIRAL LOAD IS HIGH DURING THESE TIMES
HIV cannot be spread through?
Tears, Saliva, Urine, emesis, sputum, feces, sweat, hugging, DRY KISSING, shaking hands, sharing eating utensils, attending school, working with HIV infected people, insects or formites(non-living material - necktie, stethoscope)
Why is unprotected anal sex the most risky?
Its more traumatic to the tissues and likelihood of bleeding (ouch!)
Risk is greater for the?
Receptive partner (prolonged contact with infected material - anal, vaginal, or oral sex)
Presence of blood increases the risk? When?
during menstruation, trauma to the tissues, genital lesions present from STD's
Risk of HIV infection after a?
Needle Stick. (exposure is higher with high viral load, puncture wound is deep, needle is hallow bore with visible blood, venous or arterial access with the device, or if the PT dies within 60 days.
U.S children with AIDS under 13:
90% were infected at birth (others through blood products and abuse)
What are potential influences on HIV transmission in infants?
Limit time membranes rupture before birth, mode of birth, duration of labor, exposure to cervical and vaginal secretions
ART prohylaxis AZT(zidovudine) to pregnant woman ...?....weeks of pregnancy until labor
What is recommended practice after an exposure? Mercy Policy, Iowa City for Questions, Contact Employee Health to determine risk and where to go from there. Concerns exist also about Hepatitis B and Hepatitis C exposure as well
Factors that increase risk for HIV transmission (lecture)
Prev hx of a child with HIV infection, AIDS, Preterm Birth, Low maternal CD4 count, 1st born twin, elevated maternal viral load, intrapartum blood exposure, Chorioamnionitis, failure to tx mom and fetus with AZT during prenatal period
HIV is a retrovirus discovered in 1983 (obligate parasite) it......???
must be in a living cell to replicate
HIV carries its genetic formation in?
RNA (ribonucleic acid; found in nucleus and cytoplasm of cells. Transmit genetic instructions from nucleus to cytoplasm)
So how does the HIV virus invade cells?
This is important to understand because of pharmacologic interventions!!!
HIV enters the cells after?
Binding to cell surface, then genetic material enters the cell, then Viral RNA is transcribed into Viral DNA through the assistance of TRANSCRIPTASE which is made why HIV?
HIV more specifically enters the cell when?
The gp 120 "knobs" on the virus binds of fit to specific CD4+ and chemokine receptor sites on the surface of the CD4+ T Cells (FUSION)-or knobs on
This is usually a lymphocyte
(a leukocyte or white blood cell that develops in the bone marrow - 2 forms are T-cell and B-cell)
HIV then sheds its protein coat and converts?
RNA to DNA with the assistance of REVERSE TRANSCRIPTASE (an enzyme that is made by HIV)
The Viral DNA can now enter the poor CD4+ cell's nucleus and?
With the use of INTEGRASE it becomes a permanent part of the CD4+ cell's genetic structure
Since all genetic material is replicated during cellular division, all daughter cells from the infected cells will also be infected
Because the genome (gene in the chromosome of each cell) now has a viral DNA, the cell's genetic codes CAN DIRECT CELL TO MAKE NEW HIV - small virus --> can mutate!
Production of HIV within the cell is a complicated and involved process that......?
Results in long strands of HIV RNA that must be CUT INTO appropriate lenghts
What enzyme helps cleaving or splitting these genetic strands?
Protease (one of the 1st drugs came out, worked on this enzyme)
Initial infection results in?
VIREMIA (large amounts of virus in the blood) or high viral load, very infectious time)
This is followed by a prolonged period during which?
HIV levels in the blood remains low even without treatment (happens after a few weeks and may last for 10-12 years) and few clinical symptoms are present. HIV REPLICATION IS STILL CONTINUING THOUGH! Still continuing w/o symptoms
But even without symptoms, HIV replication continues at a?
Rapid Constant rate in blood and lymph tissues early in the infection
Thus, there is a steady state of?
VIRAL LOAD (the number of copies of HIV detectable in a blood sample) that is achieved and maintained in the body of those infected for years!
In order for the body to maintain this...the body makes?
1,000,000,000 to 10,000,000,000 new viruses A DAY! Wow!
Acute illness develops?
Shortly after the virus is contracted - as the rapid rise in viral levels are present
Although HIV may remain inactive in infected cells for years, antibodies are?
Produced to its proteins - a process knows as SEROCONVERSION (detectable in blood or cells)
In the normal immune response, foreign antigens interact with B cells, which start the process of?
Why the destroy that?
Because T cells have more CD4+ RECEPTOR on their surface than other CD4+ cells, SO HIV PREFERS THESE!
The ability if HIV to destroy T cells (CD4+ cells) exceed the body's ability to replace cells
Severe immune suppression leads to?
Development of infections and cancers that cause mortality and morbidity
Infected cells fuse with other cells and can combine into a mass (syncytium) that destroys all cell involved
Initiation of destruction through the infected persons immune system and the antibodies that decrease immunity BIND AND DESTROY INFECTED CELL
2. HIV spreads throughout the body
Lymphoid tissue becomes an early reservoir for HIV/ HIV causes significant degenerative change in the lymph system/ Allows the viral particles to spill over into the blood --> leads to DECREASED IN IMMUNITY
3. HIV Spreads throughout the body
infects the monocytes/ infected monocytes move into tissues and become macrophages (phagocytic cells)/ These cells become "HIV factories" and can rupture, spreading newly formed HIV into the surrounding tissue: SKIN, CNS, LYMPH NODES, BONE MARROW, and LUNG.
Stages of HIV Infection Acute Infection
Symptoms usually occur 1-3 weeks after an initial infection and last 1-2 weeks but can persist for months./ CD4+ T cell counts temporarily fall (that dip the chart) but quickly RETURN TO BASELINE/ Most symptoms are mild - may may mistaken for a COLD or FLU/ In a few people, neurologic complications may develop(meningitis, peripheral neuropathy, facial palsy, Guillain-Barre syndrome
Stages of HIV infection Acute Infection
Seroconverting (development of HIV specific antibodies) - fever, rash, sore throat, HA, joint pain, malaise, muscle pain, Nausea, Diarrhea, and Swollen Lymph nodes.
Referred to as asymptomatic but......?
May feel......fatigue, HA, low-grade fevers, night sweats, persistant generalized lymphdenopathy (PGL) and other vague symptoms. they dont understand that they are infected
No lifestyle changes if.....?
Not aware of diagnosis/ No medical help may be sought/ Can create public health concern as they are still able to transmit HIV to others even when unaware of Dx or..........(i missed this).....
Lymphocyte T cell count drops to?
200-499 cells/uL / Viral load increase/ HIV advance to a more ACTIVE STAGE
Symptoms seen earlier get worse....
Persistent fever, frequent drenching night sweats, chronic diarrhea, recurrent HA's, fatigue severe enough to interrupt normal routines.
More localized infections
Shingles(varicella roster), Persistant vaginal....?....., Outbreaks of oral or genital herpes, and Bacterial infections
Lypmphadenopathy & Kaposi sarcoma (KS) [ cancerous tumor of the connective tissue, and is often associated with AIDS], Neurological manifestations, and Oral hairy leukoplakia.
Oropharyngeal candidiasis or Trush
Will occur in most (90%) of HIV-infected people at some time/ Whitish yellow patches IN MOUTH, ESOPHAGUS, OR GI TRACT/ Diagnosed with microscopic exam of scraping from lesion and culture
Oral Hairy Leukoplakia (look like trush, painless)
Epstein- Barr virus infection/ Painless, white, raised lesions on lateral aspects of tongue/ May be THE EARLIEST signs of HIV INFECTION/ Also an INDICATION OF DISEASE PROGRESSION
Late Chronic Infection - AIDS
Diagnosed of acquired immunodeficiency syndrome (AIDS) cannot be made until the HIV infected person meets the CDC guidelines for the case definition criteria.
Must have AT LEAST one of the criteria by CDC:
1. CD4+ T cell count drops below 200 cells/ml
2. Development of one of the opportunistic infections (Fungal, Viral....) 3. Development of one of the opportunistic cancers (KS, Burkitt's..), 4. Wasting syndrome, 5. DIMENTIA DEVELOPS
LATE CHRONIC INFECTION
These criteria are more likely to occur when the immune system becomes severely compromised/ These opportunistic conditions generally do not occur in people with FUNCTIONING IMMUNE SYSTEM/ These infections can be severe, debilitating, and life-threatening
LATE CHRONIC INFECTION
Immune system is SEVERELY COMPRIMISED/ Increased amount of HIV in the blood/ Decrease in the lymphocyte/ Advance in tx have led to significant decreases in the rates of opportunistic diseases- successful tx of HIV helps to maintain the immune system and prevent infections and cancers.

Other Opportunistic Diseases?
Lymphomas: 2 are common with AIDS (non-Hodgkin's lymphoma and CNS lymphoma or Primary Lymphoma of the brain)
40% of women with HIV have cervical dysplasia and cervical cancer, its FREQUENT and AGRESSIVE, and women with HIV should have PAP Q 6 MONTHS!
Can affect the Integumentary system, the EYE, or the GI system. Lesions on mouth, genial area or perianal mucosa, cornea or retinal lesions or pharyngeal or perioral esophageal mucosa.
Summary of HIV pathogenesis
1. HIV enters the body through sexual, parenteral, or vertical route (born with it) 2. The virus preferentially infects CD4+ T-lymphocytes, or CD4+ T cells which play a critical role in immune function 3. Viral load progressively increase as more virus is produced 4. The number of CD4+ cells progressively Decrease to a point that immune function is compromised 5. When immunosuppression becomes profound (CD4 count <200) risk of opportunistic infections and malignancies increase dramatically
Counseling session of about 30-45 minutes
Discuss why at risk and how to stay safe in the future/ Discuss the 3 month window where HIV wont be detected/ Free of charge
Confidential but name based
Under 18 years of age can have tests w/o parental notification, but if positive, parents will be notified
Diagnostic studies with HIV infection
Most usefull tests are those that detect antibodies specific to HIV
up to a 2 month time frame from infection before antibodies can be detected/ Now can be done with oral fluid and urine/ Newer tests are rapid -20 minute blood tests in the office setting- CDC recommends these
Blood tests for serum antibodies or directly to gene proteins - effective 99% for those infected 12 weeks or more
EIA (Enzyme immunoassay), abd ELISA (enzyme linked immunosorbent assay)
Diagnostic studies with HIV infection
screening tests available from the internet/ free of charge or fee associated/ OTC screening test available
Dx studies with HIV infection in the newborn
Complicated because of maternal IgG antibodies that cross the placenta after 32 WEEKS GESTATION
What are the most accurate test for THOSE UNDER 18 MONTHS?
HIV DNA PCR assay on neonatal blood/ Follow up tests at INTERVALS
CD4+ T cell count
to measure progression of HIV infection/ Decrease as the disease progresses/ Marker for decreased immune function
to assess viral activity, clinical status and disease progression/ Counts the number of viral particles in a sample of blood/ Help to determine: when to initiate therapy. efficacy of therapy and if the CLINICAL GOALS ARE BEING MET, EVEN IF THE VIRAL LOADS ARE LOW, ITS STILL ABLE TO TRANSMIT
Liver function tests?
altered, common and important for drug therapy (coinfection of hepatitis b & c.
detects drug-resistant viral mutations that are present in reverse transcriptase and protease genes.
Therapeutic Management Collaborative Care Focus

What to do in initial visit?
Gather data and establish rapport/ Psychosocial Hx and Medical Hx/ Patient education
What are some pt education?
Spectrum of THE DISEASE/ TRANSMISSION/ Improving health/ Diet review/ Family planning/contraception/ May be in state of shock, denial-process could take several months
Goals of HAART and ART?
1. Decrease the VIRAL LOAD 2. Maintain or raise CD4+ CELL count 3. Delay the development of HIV related symptoms and OPPORTUNISTIC DISEASE
Changing constantly/ The national institutes of Health (NIH) guidelines on the principles of drug therapy/ Other guidelines on the use of antiretroviral therapy also published
Resistance can happen?
rapidly if patient misses or delays dose of meds - STRICT ADHERANCE TO TX IS EXTREAMLY IMPORTANT!
Why would they use combinations of drugs from different drug groups?
Various combination attack viral replication in several different ways to : Makes is MORE DIFFICULT FOR THE VIRUS TO RECOVER and IT DECREASED LIKELIHOOD OF DRUG RESISTANCE. And also virus mutates, may have different combination, more cost effective.
Drugs used to tx HIV are?
Antiretroviral drugs (ART)/ Drugs work at various point in the HIV replication cycle
ART drug therapy can be devided into groups by action?
Nucleoside reverse transcriptase inhibitors (NRTI's), Nonnucleoside reverse transcriptase inhibitors (NNRTI's), NucleoTIDE reverse transcriptase inhibitors (NtRTI's), Protease Inhibitators (PI's) and Fusion Inhibitors (Entry Inhibitors)

Anti- inflammatory medications, Anti-infective medications, Anti-fungal medications, and Anti-viral Medications
Number of opportunistic diseases associated with HIV can be prevented through?
Use of ART, vaccines, and disease specific measures
What are the major problems with ART?
Resistance develops rapidly when they are USED ALONE OR INADEQUATE DOSES/ Need to use combination of 3 or more ART at FULL STRENGTH/ Dangerous interactions with PI's, NNRTI's and come commonly used meds, OTC meds and herbal therapy (ST JOHNS WORT INTERFERES WITH ART)
What are other issues?
Treatment protocol can reduce viral load by 90-99% in many cases, there are problems/ Some people with HIV will not experience dramatic response with ART and will cause feelings OF DESPAIR and FAULTY (why are we even trying this!)/ Many patients will not be able to use combination therapy because of? - expense, side effect, inability to adhere to REQUIRED SCHEDULES AND DIETARY CHANGES

Resistance to antiretroviral drugs is a major problem in tx HIV infection.
Ways to decrease risk for resistance?
Take at least 3 different ART drugs at a time/ Know what and how to take meds prescribed/ Take full dose on SCHEDULE/ If unable to take d/t side effects, call PCP/ understand the interactions with other meds/ understand "viral" load/ Low viral load does not mean ABSENCE OF DISEASE OF VIRUS -> STILL CAN SPREAD IT [refer page 15-23 on page 265]
Problems in developing vaccine?
HIV lives away from CIRCULATING IMMUNE FACTORS/ HIV mutates RAPIDLY/ 2 Strains of HIV (HIV 1&2) that causes AIDS and at least 9 families of HIV around the world/ Can only be tested in humans - ETHICAL ISSUES/ Vaccine will not replace current prevention methods-now need to decrease risk behaviors as no vaccine is likely to be found 100% effective/ Cultural CONSIDERATION IN OTHER COUNTRIES-FEMALE DOMINANT? LEWIS 259
4 questions to ask?
1. Have you ever had a blood transfusion or used clotting factors? 2. Have you ever shared needles, syringes, or other injecting equipment with another person? 3.
