NR 507 WEEK 1 DISCUSSION- PATHOPHYSIOLOGY
AND CLINICAL ASPECTS OF HIV A+ GRADED
SOLUTIONS 2026
Pathophysiological Mechanisms of HIV
HIV, a retrovirus, targets the immune system by infecting CD4+ T- Cells, resulting in immune
suppression. After binding to CD4 receptors, the virus enters the cells, integrates into the host’s
DNA replicates, and cause cell death. This ongoing depletion of CD+ cells diminishes immune
defenses, allowing opportunistic infections and unseals conditions to develop as immunity
weakens. As CD4+ counts decline and viral load increase, individuals may progress to Acquired
Immunodeficiency Syndrome (AIDS), a severe form of immunodeficiency (Fauci & Lane,
2020).
Explanation if Wilbur’s Clinical Manifestations
Wilbur’s flat, purple rash could indicate Kaposi’s sarcoma, a common AIDS- associated
malignancy due to immunosuppression. Additionally, the white coating on his tongue suggests
oral candidiasis (thrush), common in immunocompromised patients and a sign of advanced HIV.
His frequent illness and stem from recurrent infections linked to immune systems weakening,
aligning with HIV progression (CDC, 2021).
Analysis if Clinical Findings in Relation to HIV
Wilbur’s symptoms support HIV diagnosis, as clinical manifestations align with advanced HIV
stages, particularly opportunistic infections like thrush and AIDS-defining illness like Kaposi’s;
sarcoma. These findings likely indicate a significantly reduced CD4+ count suggestive of
advanced HIV or possible AIDS.
Diagnostic Tests for HIV
Rapid HIV antibody tests are used to detect HIV antibodies, while P24 antigen testing directly
detects the virus, facilitating early diagnosis (CDC, 2021). Additionally, a CD4+ T-Cell count
below 200 can confirm AIDS, while viral load testing measures the viruses’ activity, aiding in
diseases progression assessment and treatment monitoring (Fauci & Lane, 2020). Oral swabs for
Candida and skin biopsies for suspected Kaposi’s sarcoma are also common for evaluating
opportunistic infections in advanced HIV cases (CDC, 2021).
Anticipated Test Results
For Wilbur, a positive HIV antibody or antigen test, a low CD4+ count, and a high viral load
would support a diagnosis of advanced HIV. The presence of Candida or Kaposi’s sarcoma
would further confirm immune compromise, supporting HIV related complications.
