Summary

Recurrent Aphthous Stomatitis (RAS) severity in HIV patients correlates with immune status. Lower CD4+ cell counts and higher viral load indicate more severe RAS manifestations, particularly in AIDS patients.

Area of Science:

  • Immunology
  • Infectious Diseases
  • Oral Medicine

Background:

  • Human Immunodeficiency Virus (HIV) infection leads to immunodeficiency.
  • Immunodeficiency is linked to severe Recurrent Aphthous Stomatitis (RAS) episodes in HIV patients.

Purpose of the Study:

  • To correlate RAS manifestations with HIV-induced immunosuppression.
  • To analyze CD4+ cell counts, CD8+ cell counts, CD4+:CD8+ cell ratio, and viral load in relation to RAS severity.

Main Methods:

  • Series study involving 94 HIV-infected patients with RAS.
  • Patients were categorized into AIDS and HIV-infected groups.
  • Evaluation included CD4+, CD8+ cell counts, CD4+:CD8+ ratio, and viral load.

Main Results:

  • AIDS patients had more ulcers per outbreak (8) than HIV patients (2).
  • Major RAS patients showed lower CD4+, CD8+ cell counts, and CD4+:CD8+ ratio, with higher viral load compared to minor/herpetiform RAS.
  • No statistical difference in outcomes between minor and herpetiform RAS.

Conclusions:

  • RAS lesion emergence, especially major RAS, is directly tied to the patient's immunological status.
  • HIV-infected patients with RAS often experience nutritional deficits and lifestyle decline.
  • Diagnosing and treating RAS in HIV patients is a significant clinical challenge.
