What this trial studies

This observational study aims to gather information on the causes and progression of postpartum mastitis to develop evidence-based clinical guidelines and treatment plans, particularly regarding antibiotic use. Researchers will compare breastfeeding women with and without mastitis to analyze differences in microbial composition in milk and on the skin. The study will also investigate whether clinical symptoms differ between inflammatory and infectious mastitis and explore the impact of antibiotic treatment on bacterial composition. By collecting milk samples and questionnaires, the study seeks to fill existing knowledge gaps in mastitis management.

Who should consider this trial

Good fit: Ideal candidates for this study are pregnant mothers over 18 who can understand information in Norwegian or English and are willing to participate in questionnaires and provide biological samples.

Not a fit: Patients who are not pregnant or do not meet the language comprehension requirements may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment and prevention strategies for postpartum mastitis, benefiting breastfeeding mothers and their infants.

How similar studies have performed: While there is ongoing research into mastitis, this study's specific approach to examining microbial composition and its relationship to mastitis is relatively novel.
