Abstract:
Listeria monocytogenes is a known cause of gastroenteritis. Invasive disease can follow bacteremia causing meningoencephalitis, endocarditis and spontaneous miscarriages in immunocompromised patients and pregnant women respectively. We present the first case in England of endogenous endophthalmitis caused by L. monocytogenes following acute gastroenteritis in an immunocompetent host. A 50-year-old South Asian female presented with acute painful unilateral visual loss occurring shortly after an episode of self-limiting gastroenteritis. On examination, the eye was very inflamed with a hypopyon uveitis. A vitreous biopsy confirmed growth of L.monocytogenes serotype 1/2a. Diagnostic delay commonly occurs in endogenous endophthalmitis and exacerbates an already poor visual prognosis. Listeria spp. must be considered in ocular inflammation following gastroenteritis. The intraocular inflammation subsided but surgical intervention was required to remove vitreous debris and improve visual acuity.
Insights
This study reports the first case in England of endogenous endophthalmitis, a severe eye infection, caused by Listeria monocytogenes following gastroenteritis in an immunocompetent individual. Prompt diagnosis and treatment are crucial for preserving vision.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Microbiology
Background:
- Listeria monocytogenes commonly causes gastroenteritis.
- Invasive disease can lead to serious complications like meningoencephalitis and endocarditis, particularly in immunocompromised individuals and pregnant women.
- Endogenous endophthalmitis is a rare but severe intraocular infection.
Purpose of the Study:
- To report the first case in England of endogenous endophthalmitis caused by Listeria monocytogenes in an immunocompetent host.
- To highlight the importance of considering Listeria monocytogenes in cases of ocular inflammation following gastroenteritis.
- To emphasize the need for prompt diagnosis and management to improve visual prognosis.
Main Methods:
- Case presentation of a 50-year-old female with acute unilateral visual loss.
- Clinical examination revealing severe intraocular inflammation with hypopyon uveitis.
- Vitreous biopsy for microbiological confirmation of Listeria monocytogenes (serotype 1/2a).
Main Results:
- The patient presented with acute painful unilateral visual loss after self-limiting gastroenteritis.
- Vitreous biopsy confirmed the presence of Listeria monocytogenes.
- Intraocular inflammation subsided with treatment, but surgical intervention was necessary for visual recovery.
Conclusions:
- Listeria monocytogenes can cause endogenous endophthalmitis in immunocompetent individuals following gastroenteritis.
- Diagnostic delay in endogenous endophthalmitis negatively impacts visual outcomes.
- Ocular inflammation post-gastroenteritis warrants consideration of Listeria spp.
