Insights
Protein-energy malnutrition and incomplete immunization increase the risk of severe microbial keratitis in young children. Early intervention and nutritional support are crucial for preventing vision loss and the need for corneal transplantation.
Area of Science:
- Ophthalmology
- Pediatrics
- Infectious Diseases
Background:
- Microbial keratitis is a significant cause of vision impairment in children.
- Atraumatic microbial keratitis in preschool children presents unique challenges in diagnosis and management.
- The role of nutritional status and vaccination coverage in these cases requires further elucidation.
Purpose of the Study:
- To investigate the association between protein-energy malnutrition and immunization status and the occurrence of atraumatic microbial keratitis.
- To identify risk factors contributing to the severity and outcomes of microbial keratitis in preschool children.
- To evaluate the need for surgical intervention, such as corneal transplantation, in affected children.
Main Methods:
- A retrospective case analysis was conducted on children aged 5 years or younger.
- Data on protein-energy malnutrition, immunization profile, and microbiological findings were collected.
- Outcomes, including the need for corneal transplantation, were assessed.
Main Results:
- Severe protein-energy malnutrition was significantly linked to bilateral keratitis and incomplete immunization.
- Bacterial pathogens were identified in 82% of cases, with Staphylococcus species being most common.
- Children with severe malnutrition were more likely to require corneal transplantation.
Conclusions:
- Protein-energy malnutrition and suboptimal immunization are associated with atraumatic microbial keratitis in preschool children.
- These factors contribute to disease severity and the need for corneal transplantation.
- Addressing nutritional deficiencies and ensuring complete immunization are vital for preventing severe ocular outcomes.
Purpose:
To evaluate the role of protein energy malnutrition and immunization profile in cases of atraumatic microbial keratitis in preschool children.
Design:
Retrospective case analysis.
Methods:
Case records of all children 5 years of age and younger with atraumatic microbial keratitis treated at the Dr Rajendra Prasad Centre for Ophthalmic Sciences, New Delhi, India, between January and December 2006 were reviewed retrospectively. Main parameters evaluated were age, degree of protein-energy malnutrition, immunization profile, microbiologic profile, and final outcome.
Results:
Fifty-four consecutive children were enrolled during the study period. The mean age was 33.69 ± 21.91 months (range, 3 to 60 months). Mean weight on presentation was 10.57 ± 3.87 kg (range, 4 to 17 kg), with an average protein-energy malnutrition grade of 1.77 ± 0.74. The immunization for age was complete in 43 (80%) children. Severe protein-energy malnutrition was associated with the occurrence of bilateral keratitis (P < .001) and incomplete immunization (P < .001). Positive bacterial culture results were obtained in 44 (82%) cases, with Staphylococcus species being the most prevalent isolate (33/44; 75%). Cases requiring emergency corneal transplantation (24%) were associated with severe protein-energy malnutrition (P < .00) and bilaterality (P < .00). In multivariate analyses, cases without severe protein-energy malnutrition were 36% less likely to undergo any kind of surgical intervention (odds ratio, 0.64; 95% confidence interval, 0.04 to 0.91).
Conclusions:
Our study highlights the association of protein-energy malnutrition and immunization profile with the occurrence of atraumatic microbial keratitis in preschool children. Most of these cases required corneal transplantation surgery to preserve the ocular integrity and to restore vision.
