Abstract:
We examined microbic infections and topical immunity in 36 AIDS patients with rhinosinusitis (AIDS CDC stage IV b-d) who had an average serum CD4 count of 90/microliters. We also examined the presence of the HIV genome in nasal mucous. Microbiological examination revealed an increased number of fungal infections in addition to bacterial infections with multiresistant strains. There was no evidence of CD4-T cells or HIV reverse transcriptase. The size of study was too small to permit generalised conclusions about the infectious risk of nasal mucous.
Insights
AIDS patients with advanced rhinosinusitis showed increased fungal and drug-resistant bacterial infections in nasal mucous. Further research is needed to understand the infectious risk in these patients.
Area of Science:
- Immunology
- Microbiology
- Infectious Diseases
Context:
- Investigating microbic infections and topical immunity in individuals with advanced Acquired Immunodeficiency Syndrome (AIDS).
- Focusing on patients diagnosed with rhinosinusitis, specifically at CDC stage IV b-d.
- Assessing the immunological status with an average serum CD4 count of 90 cells/microliter.
Purpose:
- To examine the types of microbic infections present in the nasal mucous of AIDS patients with rhinosinusitis.
- To investigate the presence of the Human Immunodeficiency Virus (HIV) genome within the nasal mucous.
- To evaluate topical immunity markers, including CD4-T cells and HIV reverse transcriptase, in the nasal environment.
Summary:
- Microbiological analysis revealed a higher prevalence of fungal infections alongside bacterial infections, including multidrug-resistant strains, in the nasal mucous of the studied AIDS patients.
- No evidence of CD4-T cells or HIV reverse transcriptase was detected in the nasal mucous samples.
- The study included 36 AIDS patients with rhinosinusitis and an average CD4 count of 90/microliter.
Impact:
- Highlights the potential for opportunistic fungal and multidrug-resistant bacterial infections in the sinonasal tract of advanced AIDS patients.
- Suggests a potential disconnect between systemic viral load and local mucosal immunity within the nasal passages.
- Underscores the need for larger studies to establish definitive conclusions regarding the infectious risks associated with nasal mucous in this vulnerable population.
