Phagocytic and bactericidal activity of granulocytes in diabetic children
Insights
Diabetic children’s granulocytes show normal staphylococcus absorption but reduced ability to kill bacteria. This suggests impaired immune function in pediatric diabetes, impacting infection defense.
Area of Science:
- Immunology
- Pediatrics
- Endocrinology
Background:
- Granulocytes are key immune cells involved in fighting bacterial infections.
- Pediatric diabetes mellitus can affect various bodily functions, including immune responses.
Purpose of the Study:
- To evaluate the phagocytic and bactericidal activity of granulocytes in children with and without diabetes.
- To assess the influence of specific antigens and antitoxins on these granulocyte functions.
Main Methods:
- Study included 30 diabetic children and 40 healthy children aged 6-18 years.
- Assessed granulocyte phagocytosis (staphylococcus absorption) and bactericidal activity (intercellular killing).
- Tested the effects of candidal antigen, tuberculin antigen, and staphylococcal antitoxin.
Main Results:
- Granulocytes from diabetic children exhibited normal staphylococcus absorption capacity.
- A significant decrease in the intercellular killing of bacteria was observed in granulocytes from diabetic children.
- Antigen and antitoxin influences were also tested, with specific outcomes detailed in the full study.
Conclusions:
- Children with diabetes have impaired bactericidal activity of granulocytes, despite normal phagocytic capacity.
- This suggests a compromised immune defense mechanism in pediatric diabetes, potentially increasing infection risk.
Abstract:
Phagocytic and bactericidal activity of granulocytes were estimated in granulocytes of normal and diabetic children. The influence of candidal, tuberculin antigens, and staphylococcal antitoxin on these parameters was also tested. Thirty diabetic and forty healthy children made up the study group. Their ages were 6-18 yr. The disease duration was from 1 to 12 yr. Granulocytes from diabetic children demonstrated a normal ability to absorb staphylococcus. On the other hand, the capacity for intercellular killing of bacteria by granulocytes of diabetic children was decreased.
