Asian birth cohort studies on allergic diseases: The A2BC network initiative.

The Asia Allergy Birth Cohort (A2BC) network consolidates data from multiple independently established birth cohorts across Asia to enhance research on host-environment interactions in allergic diseases. These cohorts, established at different times with various methodologies, are reliable data sources. Our aim is to introduce the content, variables, and outcomes of these cohorts while highlighting their differences, laying the groundwork for future collaborative research.

Anaphylaxis post-COVID-19 vaccinations in Singapore.

Introduction: Anaphylaxis was the first serious adverse event (AE) of special interest surfaced in Singapore following coronavirus disease 2019 (COVID-19) vaccination. Individuals who developed physician-diagnosed severe allergic reactions to the mRNA vaccines would be medically ineligible for mRNA vaccines and offered non-mRNA alternatives. This paper describes anaphylaxis reports received by the Health Sciences Authority (HSA) and presents a review of individuals who received heterologous COVID-19 vaccination.

Maternal and Infant Dietary Patterns Are Not Related to Food Allergy Risk in Singapore Children: GUSTO Cohort Study.

Background: We previously reported that delayed allergenic food introduction in infancy did not increase food allergy risk until age 4 y within our prospective cohort. However, it remains unclear whether other aspects of maternal or infant diet play roles in the development of childhood food allergy.

Objectives: We examined the relationship between maternal pregnancy and infant dietary patterns and the development of food allergies until age 8 y.

Growing Up in Singapore with allergies - Lessons learnt from the GUSTO & S-PRESTO cohorts.

Healthcare systems across the world face major challenges due to allergic diseases, known to affect people of all ages. In Singapore, two prominent cohort studies, Growing Up in Singapore Towards healthy Outcomes (GUSTO) and the Singapore PREconception Study of long-Term maternal and child Outcomes (S-PRESTO), have made notable advancements to our knowledge and understanding of allergic diseases. These cohorts, which comprised of healthy mother-infant dyads recruited from the healthy Singapore population, have shed light on the complex connections between factors influencing health in early life, preconception and pregnancy, on the pathogenesis of allergic disorders in offspring.

Clinical predictors of wheeze trajectories and associations with allergy in Asian children.

Background: Childhood wheezing is a highly heterogeneous condition with an incomplete understanding of the characteristics of wheeze trajectories, particularly for persistent wheeze.

Objective: To characterize predictors and allergic comorbidities of distinct wheeze trajectories in a multiethnic Asian cohort.

Methods: A total of 974 mother-child pairs from the prospective Growing Up in Singapore Towards healthy Outcomes (GUSTO) cohort were included in this study.
