Human Immunodeficiency Virus Infection and Acquired Immunodeficiency Syndrome / Care of the Child with HIV Infection or AIDS

NCLEX Review Guide: Care of the Child with HIV Infection or AIDS

Pathophysiology and Transmission

HIV Infection in Children

  • HIV (Human Immunodeficiency Virus) attacks CD4+ T-helper cells, progressively destroying the immune system and leading to opportunistic infections and malignancies.
  • In children, vertical transmission from mother to child accounts for 90% of pediatric HIV cases through pregnancy, labor/delivery, or breastfeeding.
  • Other transmission routes include blood transfusions, sexual abuse, and needle sharing in adolescents.

Key Points

  • Maternal viral load is the strongest predictor of mother-to-child transmission
  • Risk of transmission can be reduced to <2% with proper antiretroviral therapy

Clinical Manifestations

Signs and Symptoms

  • Failure to thrive with poor weight gain, delayed growth, and developmental delays are early indicators in infants.
  • Recurrent opportunistic infections including Pneumocystis jirovecii pneumonia (PCP), candidiasis, and cytomegalovirus.
  • Chronic diarrhea, persistent fever, and lymphadenopathy are common presenting symptoms.
  • Neurological manifestations include developmental regression, seizures, and progressive encephalopathy.

Memory Aid: "CHILD HIV"

  • Chronic infections
  • Hepatomegaly/splenomegaly
  • Immune deficiency
  • Lymphadenopathy
  • Developmental delays
  • Heart disease (cardiomyopathy)
  • Interstitial pneumonia
  • Viral load elevation

Diagnostic Testing and Monitoring

Laboratory Studies

  • HIV DNA PCR is the gold standard for diagnosis in children <18 months due to maternal antibodies crossing the placenta.
  • CD4+ count and percentage indicate immune system status, with normal values varying by age.
  • Viral load testing measures HIV RNA copies and guides treatment effectiveness.

Age-Specific CD4+ Normal Values

AgeCD4+ CountCD4+ Percentage
0-11 months>1500 cells/mm³>34%
1-5 years>1000 cells/mm³>25%
6+ years>500 cells/mm³>25%

Treatment and Management

Antiretroviral Therapy (ART)

  • Highly Active Antiretroviral Therapy (HAART) combines multiple drug classes to suppress viral replication and preserve immune function.
  • Treatment goals include achieving undetectable viral loads, maintaining/restoring immune function, and preventing disease progression.
  • Medication adherence is critical - missing doses can lead to viral resistance and treatment failure.
  1. Assess baseline laboratory values (CD4+, viral load, CBC, liver function)
  2. Initiate combination therapy with 2-3 antiretroviral medications
  3. Monitor for side effects and drug interactions
  4. Evaluate treatment response at 4-8 week intervals
  5. Adjust therapy based on viral load suppression and tolerability

Key Points

  • Start ART in all HIV-positive children regardless of symptoms or CD4+ count
  • Medication dosing is weight-based and requires frequent adjustments as child grows

Nursing Care and Interventions

Primary Nursing Considerations

  • Infection prevention through strict hand hygiene, avoiding exposure to communicable diseases, and maintaining up-to-date immunizations (live vaccines contraindicated).
  • Nutritional support with high-calorie, high-protein diet to promote growth and combat wasting syndrome.
  • Psychosocial support for child and family dealing with chronic illness stigma and disclosure issues.
  • Medication adherence education using age-appropriate strategies and pill organizers.

Clinical Scenario

A 4-year-old with HIV presents with white patches in the mouth and difficulty swallowing. The nurse should:

  • Recognize signs of oral candidiasis
  • Provide soft, cool foods and avoid acidic items
  • Administer prescribed antifungal medications
  • Monitor for systemic spread of infection

Immunization Guidelines

  • GIVE: Inactivated vaccines (IPV, DTaP, Hib, pneumococcal, influenza)
  • AVOID: Live vaccines (MMR, varicella, live influenza) unless severely immunocompromised
  • SPECIAL: Additional vaccines (pneumococcal, meningococcal) may be recommended

Commonly Confused Points

HIV vs. AIDS in Children

HIV InfectionAIDS
Positive HIV test with CD4+ >200CD4+ <200 OR AIDS-defining illness
May be asymptomaticSymptomatic with opportunistic infections
Can live normal lifespan with treatmentAdvanced stage requiring intensive management

Study Tips

  • Remember: HIV is the virus, AIDS is the syndrome that develops in advanced stages
  • Focus on infection prevention - it's the #1 priority in immunocompromised children
  • Maternal antibodies persist until 12-18 months, making early diagnosis challenging

Quick Check

  • ☐ Can you explain why live vaccines are contraindicated in HIV-positive children?
  • ☐ Do you know the difference between HIV DNA PCR and antibody testing in infants?
  • ☐ Can you identify signs of opportunistic infections in pediatric HIV patients?
  • ☐ Do you understand the importance of medication adherence in preventing resistance?

Common Pitfalls

  • Don't confuse HIV antibody tests (unreliable in infants) with HIV DNA PCR (diagnostic gold standard)
  • Remember that CD4+ normal values are age-dependent - what's normal for adults may be low for children
  • Avoid isolation unless child has active opportunistic infection requiring precautions

You're mastering complex pediatric HIV care! Remember that these children can live healthy, productive lives with proper treatment and nursing care. Your knowledge and compassion make all the difference in their outcomes. Keep studying - you've got this! 🌟
