The Role of Cow's Milk Protein Sensitization through TH-1 and TH-2 Lymphocyte Activity and Allergic and Environmental Risk Factors in the Occurrence

Introduction

Allergies have become a growing concern in recent decades, with a significant increase in prevalence among children, particularly infants. One of the primary causes of allergies in children is the sensitization of allergens, including cow's milk protein. The complex interactions between genetic factors, allergen exposure, and environmental factors play a crucial role in the development of allergic mechanisms. Meni, an initial symptom of respiratory disorders, often occurs due to allergic reactions. Children from families with a history of allergic diseases have a higher risk of experiencing this condition than children without a history of allergies in their families.

The Importance of Understanding Allergic Mechanisms

Allergic mechanisms involve the activation of immune cells, including TH-1 and TH-2 lymphocytes. TH-1 cells play a role in cell-mediated immunity, while TH-2 cells are involved in the production of IgE antibodies, which are responsible for triggering allergic reactions. The imbalance between TH-1 and TH-2 activity has been linked to the development of allergic diseases. Understanding the role of TH-1 and TH-2 lymphocytes in allergic mechanisms is essential for the development of effective treatments and prevention strategies.

Research Purpose and Methodology

This study aims to explore the role of sensitization of cow's milk allergens in the activity of TH-1 and TH-2 lymphocytes as well as allergic risk factors related to the environment and wheezing events in infants aged up to 1 year. The study was conducted at the General Hospital Dr. Zainoel Abidin Banda Aceh using an analytical observational design with a cohort approach. Samples were taken with consecutive techniques based on a single sample formula to estimate the proportion of the population, producing 71 samples that met the inclusion criteria. The examination was carried out with a skin puncture test as a diagnostic procedure by an allergic and immunological specialist, as well as taking peripheral blood for the analysis of IL-5 and IFN-γ levels at the Prodia Jakarta laboratory. Monitoring was carried out regularly to evaluate allergic complaints for one year.

Research Results

From 71 subjects followed to the age of 12 months, a wheezing incident was 64.8%. Subjects with low allergic risk reached 67.6%, while high allergic risk was 32.4%. Bivariative analysis shows a significant relationship between IL-5 levels and skin skewer test results. Allergic risk factors, cow's milk test results, IFN-γ levels, IL-5 levels, and father's smoking habits (indoor) have all significant relationships with wheezing complaints. However, the history of labor, history of breastfeeding, and sex do not show a significant relationship.

Discussion

The results showed that there were differences in IL-5 levels and the results of the skin puncture test in groups with wheezing symptoms and without wheezing. This difference shows that TH-2 activity, which is characterized by an increase in IL-5 levels, plays an important role in the development of allergic symptoms in infants. In multivariate analysis, IFN-γ levels, IL-5 levels, and father's smoking habits have proven to have a significant effect on the event of wheezing.

This finding also shows a shift in allergic patterns in Aceh, where the symptoms of wheezing began to appear at the age of 4-6 months as an early sign of asthma and dermatitis. IL-5 levels above 0.6 pg/ml show a reliable TH-2 profile in determining allergies, with an area under the curve (AUC) of 86%.

Conclusion

This study confirms a significant relationship between IL-5 levels and the results of skin skewers tests, as well as risk factors for allergic to wheezing incidence. Different IL-5 levels between Menyi and Non-Meni Groups and the influence of father's smoking habits are important determinants in the management and prevention of allergies in infants. This finding emphasizes the importance of monitoring and handling allergic risk factors in the environment to reduce the event of wheezing in infants.

Implications for Public Health

The findings of this study have significant implications for public health. The identification of risk factors for allergic diseases, including cow's milk protein sensitization, TH-1 and TH-2 lymphocyte activity, and environmental factors, can inform the development of effective prevention and treatment strategies. The results of this study highlight the importance of monitoring and handling allergic risk factors in the environment to reduce the event of wheezing in infants. This can be achieved through education and awareness programs, as well as the implementation of policies and interventions that promote a healthy environment for infants.

Future Research Directions

This study provides a foundation for future research in the field of allergy and immunology. Further studies are needed to explore the mechanisms underlying the development of allergic diseases, including the role of TH-1 and TH-2 lymphocytes. Additionally, research is needed to identify effective prevention and treatment strategies for allergic diseases, including the use of immunotherapy and other interventions. The findings of this study also highlight the need for further research on the impact of environmental factors on the development of allergic diseases.

Limitations of the Study

This study has several limitations. The sample size was relatively small, and the study was conducted in a single hospital setting. Additionally, the study relied on a single diagnostic procedure, the skin puncture test, which may not be sensitive enough to detect all cases of allergic disease. Further studies are needed to confirm the findings of this study and to explore the mechanisms underlying the development of allergic diseases.

Conclusion

In conclusion, this study provides new insights into the role of cow's milk protein sensitization through TH-1 and TH-2 lymphocyte activity and allergic and environmental risk factors in the occurrence of wheezing in infants. The findings of this study highlight the importance of monitoring and handling allergic risk factors in the environment to reduce the event of wheezing in infants. This study provides a foundation for future research in the field of allergy and immunology and has significant implications for public health.
Frequently Asked Questions (FAQs) about the Role of Cow's Milk Protein Sensitization in Allergic Diseases

Q: What is cow's milk protein sensitization?
