Tear electrophoretic changes in Nigerian children after measles
Insights
Measles infection alters tear protein patterns in Nigerian children, indicating inflammation. Malnutrition in recovering children revealed an additional tear protein peak, identified as serum transferrin.
Area of Science:
- Ophthalmology
- Pediatrics
- Immunology
Background:
- Measles infection can cause ocular complications.
- Tear protein analysis offers insights into ocular health.
- Nutritional status may influence disease recovery and protein profiles.
Purpose of the Study:
- To investigate changes in tear protein electrophoresis during and after measles infection in Nigerian children.
- To identify specific protein alterations associated with measles and malnutrition.
Main Methods:
- Tear electrophoresis on cellulose acetate support was performed on 56 Nigerian children (32 with measles, 24 controls).
- Electrophoresis on polyacrylamide cellulose gel and immunoelectrophoresis were used for further protein identification.
Main Results:
- Children with measles showed tear protein patterns consistent with inflammation, most severe in the first week post-infection.
- Patterns began recovering by the third week.
- Malnourished children four weeks after measles exhibited an additional protein peak, identified as serum transferrin.
Conclusions:
- Measles infection significantly alters the normal tear protein pattern, reflecting inflammatory processes.
- Serum transferrin elevation in tear fluid is associated with malnutrition in children recovering from measles.
- Tear protein electrophoresis is a valuable tool for assessing ocular health in pediatric infectious diseases.
Abstract:
At the laboratory of the National Centre of Ophthalmology, Paris, tear electrophoresis on cellulose acetate support was studied in 56 Nigerian children--32 during and shortly after measles infection and 24 healthy controls. The controls had a normal pattern, while those with measles had patterns consistent with inflammation, most severe in the first week but showing varying degrees of recovery by the third week. Four weeks after measles all cases suffering from malnutrition had patterns with an additional peak. This was shown on further investigation by electrophoresis on polyacrylamide cellulose gel and immunoelectrophoresis to be due to serum transferrin. The normal protein pattern of tears is shown to be altered during and after measles infection.
