|---|---|---|---|---|---|
| Acute Retroviral Syndrome | Viral replication occurs during the acute infection period. Seroconversion is the development of antibodies from HIV. These symptoms may last approximately 1 to 2 weeks (sometimes several months).
🗑
|
||||
| HIV: early infection | (1) The median time between HIV infection and the development of end-stage HIV disease or AIDS in an untreated individual this is anywhere from 10 to 14 years. Asymptomatic.
🗑
|
||||
| HIV: Early Symptomatic Disease | CD4+ cell count drops below 500 cells/mm3. Idiopathic fevers, night sweats, chronic diarrhea, HA & fatigue.
physical exam may reveal persistent generalized lymphadenopathy (PGL).
🗑
|
||||
| AIDS | end-stage, or terminal phase, of the spectrum of HIV infection.
🗑
|
||||
| AIDS: Criteria for diagnosis | As HIV progresses, the CD4+ lymphocytes cell count decreases and the ratio of CD4+ to CD8+ cells (T-helper to T-suppressor cells), normally 2 to 1, gradually shifts resulting in more T-suppressor cells.
🗑
|
||||
| HIV-1 | More rapid onset
🗑
|
||||
| HIV-2 | Slower onset.
🗑
|
||||
| AIDS (Infected person's CD4+ Count) | cell count of < to 200 cells/mm3.
🗑
|
||||
| HIV: modes of transportation | Unsafe sexual practice.
Sharing needles (sharps).
Blood transfusion.
Vertical transmission.
🗑
|
||||
| HIV: The three most common modes of transmission are | (1) Anal or vaginal intercourse.
(2) Contaminated drug-injecting equipment.
(3) Transmission from mother to child.
🗑
|
||||
| Opportunistic Diseases associated with AIDS: Respiratory | Pneumocystis jiroveci pneumonia (PCP), fever, night sweats, non-productive cough, progressive shortness of breath, pneumonia, malaise, vesicular eruptions on the tracheobronchial mucosa, chest pain, hemoptysis.
🗑
|
||||
| Opportunistic Diseases associated with AIDS: Integumentary | vesicular eruptions on mouth and perianal area, shingles, Kaposi’s sarcoma, erythematous papules and nodules.
🗑
|
||||
| Opportunistic Diseases associated with AIDS: Eye | Lesions of the retina, blurred vision, loss of vision, ocular and/or corneal lesions, visual field defects.
🗑
|
||||
| Opportunistic Diseases associated with AIDS: Gastrointestinal | watery diarrhea, abdominal pain, weight loss, nausea, stomatitis, esophagitis, gastritis, colitis, bloody diarrhea, whitish-yellow patches in mouth, esophagus and GI tract.
🗑
|
||||
| Opportunistic Diseases associated with AIDS: Neurologic | cognitive dysfunction, motor impairment, fever, headache,
seizures, decrease LOC, hemiparesis, mental and motor declines with progressive multifocal leukoencephalopathy, stiff neck, personality changes, aphasia.
🗑
|
||||
| HIV disease: Pathophysiology | Requires cells for replication. Released into lymphatic system (binds to CD4+lymphocytes). Reproduces quickly.
🗑
|
||||
| Diagnostic tests for HIV | ELISA or enzyme immunoassay (EIA), antibody tests that detect the presence of HIV antibodies. CD4+ cell monitoring. Viral load monitoring.
🗑
|
||||
| CD4+ cell monitoring | Tracks progression of HIV disease. Its the best marker for immunodeficiency with HIV. Used in making decisions about drug therapy.
🗑
