Investigating the effects of breast milk from mothers with metabolic diseases on infant health after dietary changes

The Role of Breast Milk Neutrophils From Mothers With Metabolic Diseases and Impact on Infant Development and Response to Pulmonary Infections

Not applicable Interventional Fundación Pública Andaluza para la Investigación de Málaga en Biomedicina y Salud · NCT06833554

This study is testing how changes in the diet of mothers with gestational diabetes or obesity affect the breast milk they produce and whether that impacts their infants' health, particularly regarding infections and development.

What this trial studies

This project aims to analyze variations in breast milk neutrophils from lactating mothers with gestational diabetes or obesity and how a dietary intervention with Omega-3 fatty acids influences these changes. The study will evaluate the incidence of respiratory infections in infants, their development, and the impact on gut microbiota and epigenetic modifications. Blood and milk samples will be collected from three groups of mothers: control, obesity, and gestational diabetes, to study neutrophil populations using flow cytometry. The research seeks to understand the role of breast milk in neonatal microbiota and immune response to lung infections.

Who should consider this trial

Good fit: Ideal candidates are lactating mothers aged 18-50 with full-term pregnancies who intend to exclusively breastfeed for at least three months.

Not a fit: Patients who have preterm pregnancies, multiple deliveries, or significant maternal health complications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance our understanding of how maternal nutrition impacts infant health and immune responses.

How similar studies have performed: While there is ongoing research into maternal nutrition and infant health, this specific approach focusing on neutrophils and dietary intervention is relatively novel.
