Unsuspected human immunodeficiency virus in critically ill emergency patients
JAMA
|May 15, 1987
Summary
Three percent of critically ill emergency patients had unsuspected human immunodeficiency virus (HIV) infection. These HIV-positive individuals were actively bleeding trauma victims, highlighting the need for universal precautions for all bleeding patients.
Area of Science:
- Emergency Medicine
- Infectious Diseases
- Public Health
Background:
- Unsuspected human immunodeficiency virus (HIV) infection can pose risks in emergency settings.
- Critically ill patients may present with conditions requiring immediate intervention, complicating infection screening.
Purpose of the Study:
- To determine the prevalence of unsuspected HIV infection among critically ill emergency patients.
- To identify characteristics of HIV-seropositive patients in this population.
Main Methods:
- Anonymous serum samples from 203 critically ill or severely injured patients without a history of HIV were tested.
- Enzyme-linked immunoassay and Western blot analysis were used for HIV antibody detection.
Main Results:
- Six patients (3%) were seropositive for HIV antibody.
- All HIV-positive patients were actively bleeding trauma victims aged 25-34, representing 16% of trauma patients in this age group.
- Intravenous drug abuse history was not a reliable indicator for identifying seropositive individuals.
Conclusions:
- Universal infection-control precautions are essential for emergency department and prehospital care providers treating bleeding patients.
- These precautions should be implemented regardless of suspected HIV status due to the prevalence of unsuspected infections.

01:29Pulmonary Tuberculosis I
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

01:27Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
