II. Epidemiology

  1. HIV and Tobacco Abuse both play major roles in the increased risk of COPD and Lung Cancer in HIV patients
    1. Collini (2016) Curr Opin Infect Dis 29(1):31-8 +PMID:26555039 [PubMed]

III. Causes: General lung findings in HIV

  1. Typical Bacterial Pneumonias are the most common Bacterial Pneumonias seen in HIV and AIDS patients
    1. Pneumococcal Pneumonia
    2. HaemophilusInfluenzae
    3. Staphylococcus aureus
    4. Pseudomonas aeruginosa (less common)
  2. Mycobacterium
    1. Tuberculosis
      1. May occur at any CD4, but especially occurs in advanced HIV with CD4 < 500
      2. Suggestive findings include cavitary lesions, fever >7 days, weight loss
      3. More common with incarceration, Homelessness, congregate housing, travel to endemic regions
    2. Mycobacterium Avium Complex or MAC (AIDS)
  3. Parasitic
    1. Toxoplasmosis
  4. Viruses (CD4 <50)
    1. Cytomegalovirus (CMV)
    2. Herpes Simplex Virus (HSV)
  5. Fungal (advanced HIV and AIDS)
    1. CD4<200
      1. Pneumocystis jiroveci Pneumonia (PCP Pneumonia)
        1. Interstitial Infiltrates AND Thrush (Odds Ratio 11.8)
        2. Other predictive findings include exertional Dyspnea, inspiratory crackles, subacute disease course
    2. CD4<50
      1. Cryptococcus
      2. Histoplasmosis
      3. Aspergillosis
      4. Candidiasis
    3. Other less common endemic fungi (consider in those living in or traveling to endemic regions)
      1. Coccidioidomycosis
      2. Blastomycosis
  6. Malignancy
    1. Kaposi's Sarcoma
    2. Non-Hodgkin's Lymphoma

IV. Causes: Cavitary Lesions

  1. Tuberculosis
  2. Aspergillus
  3. Pneumocystis jiroveci Pneumonia (Pneumocystis carinii)
  4. Pneumococcus
  5. Cryptococcus neoformans
  6. Rhodococcus equi
  7. Gram Negative Bacilli (especially Pseudomonas)

V. Causes: Nodular lesions

  1. Cryptococcus
  2. Histoplasmosis
  3. Tuberculosis
  4. Pneumocystis carinii
  5. Bacterial Pneumonia
  6. Malignancies
    1. Kaposi's Sarcoma
    2. Non-Hodgkin's Lymphoma

VI. Causes: Hilar Adenopathy

  1. Tuberculosis
  2. Kaposi's Sarcoma
  3. Non-Hodgkin's Lymphoma
  4. Pneumocystis carinii (Uncommon)

VII. Causes: Pleural Effusion

  1. Tuberculosis
  2. Fungal Pneumonia
  3. Kaposi's Sarcoma
  4. Non-Hodgkin's Lymphoma

VIII. Prevention

  1. Tobacco Cessation
  2. Pneumococcal Vaccine
  3. Influenza Vaccine
