Insights

Bacterial ocular infections like Pseudomonas corneoscleritis and keratitis are emerging threats in patients with human immunodeficiency virus (HIV). These serious infections often resist standard antibiotic treatment, especially with neutropenia.

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Immunology

Background:

  • Patients with human immunodeficiency virus (HIV) are typically susceptible to opportunistic infections.
  • Ocular bacterial infections are uncommon in acquired immunodeficiency syndrome (AIDS) patients, with limited prior reports.
  • This study highlights a recent increase in severe bacterial ocular infections in HIV-positive individuals.

Observation:

  • Two cases of Pseudomonas corneoscleritis and one case of Pseudomonas keratitis were observed in HIV-infected patients.
  • These infections demonstrated resistance to conventional antibiotic therapies.
  • Identified predisposing factors included extended-wear soft contact lens use and exposure secondary to Bell's palsy.

Findings:

  • All three patients presented with neutropenia, a condition that may have impaired their response to treatment.
  • Two patients required enucleation due to overwhelming ocular infection.
  • Pseudomonas keratitis in HIV-infected patients is a severe condition with a poor prognosis.

Implications:

  • Early diagnosis and aggressive treatment are crucial for managing Pseudomonas keratitis in HIV patients.
  • The findings suggest a need for increased vigilance regarding bacterial ocular infections in immunocompromised populations.
  • Corneoscleritis in HIV patients, particularly with Pseudomonas, may necessitate more aggressive interventions than in immunocompetent individuals.
