Abstract

Insights

Serratia marcescens caused corneal ring infiltrates in a contact lens wearer with human immunodeficiency virus (HIV-1). Intensive topical antibiotic treatment yielded favorable outcomes for this severe keratitis case.

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Microbiology

Background:

  • Contact lens wear is a significant risk factor for microbial keratitis.
  • Human immunodeficiency virus (HIV-1) infection can predispose individuals to opportunistic infections, including ocular infections.

Observation:

  • A case study identified corneal ring infiltrates in a 29-year-old male contact lens wearer with a history of HIV-1 infection.
  • The patient presented with blurred vision, redness, and ring-shaped corneal infiltrates in the left eye, with initial visual acuity of hand movement in both eyes.

Findings:

  • Corneal scrapings and contact lens cultures confirmed infection by *Serratia marcescens*.
  • The patient's corneal ulcer responded well to topical gentamycin sulfate treatment.
  • Despite treatment, the final visual acuity remained hand movement.

Implications:

  • This case highlights *Serratia marcescens* as a causative agent of corneal ring infiltrates in immunocompromised contact lens wearers.
  • Prompt diagnosis and intensive topical antibiotic therapy are crucial for managing *S. marcescens* keratitis in HIV-1 patients.
  • Contact lens hygiene and regular eye examinations are essential for individuals with HIV-1 to prevent severe ocular infections.

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

Sexually Transmitted Infections

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Endocarditis II: Clinical Features of Infective Endocarditis

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
