Assessing the Microbiological Spectrum of Dacryocystitis Patients at a Tertiary Eye Hospital: A Retrospective Study
Rawan Althaqib
Purpose
To determine the microbiological spectrum and the demographics of dacryocystitis patients.
Methods
A retrospective chart review was used to collect data on patients who presented with dacryocystitis at King Khaled Eye Specialist Hospital between (2018-2022). Data were collected on demographics, type of organism, antibiotic sensitivity, response to antibiotics therapy, management, and complications.
Results
In a total of 97 patients, gram-positive cultures predominated in all genders in both adult and pediatric age groups and accounted for 61.3% of the sample. In adults, Staphylococcus aureus is the leading gram-positive organism (25.7%) while Pseudomonas aeruginosa (7.9%) and Haemophilus influenzae (6.9%) were the most common gram-negative organisms. In pediatric cases, Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus pyogenes, and Streptococcus intermedius were equally prevalent and gram-negative infection was exclusively due to Haemophilus species (26%).
Conclusion
Comprehending the microbiologic spectrum and its trend is crucial for managing an infection and recommending suitable antibiotic therapy. Initial Empirical therapy for dacryocystitis cases is targeted toward the Gram-positive organisms due to its prevalence. Physicians need to be cautious when dealing with nonresponsive cases, as these could be signs of a gram-negative, mixed, or methicillin-resistant Staphylococcus aureus (MRSA) infection. As a result, we heartily advise cultures with sensitivity testing at the time of presentation since it will improve the response to antibiotic therapy and help mitigate antibiotic resistance. as well as conducting a local study from time to time to assess the trend in the microbiological spectrum and shift in epidemiology, along with the sensitivity to the antibiotics.
