Beskrivelse
Inclusion Criteria:
- Preterm infants with a gestational age between 28 and 37 weeks (inclusive of 28 weeks)
- Documented history of neonatal intravenous antibiotic exposure for at least 5 consecutive days during the neonatal period (e.g., in the NICU).
- Corrected age of 6 months ± 7days at the time of enrollment.
- No systemic antibiotic usage within 14 days prior to screening.
- Legal guardians are willing to sign the informed consent form and comply with the 6-month intervention and follow-up schedule.
Exclusion Criteria:
- Severe congenital malformations, chromosomal abnormalities, or inherited metabolic diseases (e.g., Down syndrome).
- Severe neurological disorders or structural brain injuries (e.g., Grade III/IV intraventricular hemorrhage, cystic periventricular leukomalacia, or hydrocephalus requiring a shunt).
- Severe chronic diseases affecting growth and development (e.g., congenital heart disease requiring surgery, short bowel syndrome, or severe sequelae of necrotizing enterocolitis).
- Concurrent participation in other interventional clinical trials.
- Planned long-term use of other commercial probiotic/prebiotic supplements outside the study protocol during the intervention period.
- High risk of loss to follow-up (e.g., expected relocation).

Eksperimentel: Probiotic Intervention Group
Preterm infants in this group will receive standard care plus a daily oral probiotic mixture for 6 months.
|
Daily oral administration of a probiotic mixture containing Bifidobacterium animalis subsp.
lactis Bb-12 and Lacticaseibacillus rhamnosus LGG at a dose of 3 x 10^9 CFU/day for 6 months.
|
|
Ingen indgriben: Standard Care Group
Preterm infants in this group will receive routine neonatal follow-up and standard infant feeding practices without additional probiotic supplementation for 6 months.

|
Mean Neurodevelopmental Assessment Score
Tidsramme: Baseline and 6 months post-intervention
|
Neurodevelopmental status evaluated using the Gesell Developmental Schedules (yielding Developmental Quotients [DQs]) or the Ages & Stages Questionnaires, Third Edition (ASQ-3). The reported value in the results data table will be the mean score of the participants in each group.

Tidsramme |
|---|---|---|
|
Change from Baseline in Gut Microbiota Alpha Diversity (Chao1 and Shannon Index Values)
Tidsramme: Baseline and 6 months post-intervention
|
Evaluation of longitudinal changes in gut microbiota alpha diversity based on 16S ribosomal RNA (16S rRNA) gene sequencing.
The results data table will report the mean change from baseline in Chao1 and Shannon indices (dimensionless scores).
|
Baseline and 6 months post-intervention
|
|
Relative Abundance of Specific Gut Microbiota Taxa
Tidsramme: Baseline and 6 months post-intervention
|
The percentage of key bacterial groups (specifically targeting the supplemented strains Bifidobacterium and Lacticaseibacillus) relative to total sequences, determined via 16S rRNA gene sequencing.
The results data table will report the mean relative abundance percentage (%)
|
Baseline and 6 months post-intervention
|
|
Concentration of Fecal Short-Chain Fatty Acids (SCFAs)
Tidsramme: Baseline, 3 months and 6 months post-intervention
|
Concentrations of specific fecal short-chain fatty acids (including acetate, propionate, and butyrate) quantified using gas chromatography-mass spectrometry (GC-MS) targeted metabolomics.
The results data table will report the mean concentration in micromoles per gram (umol/g) of wet feces.
|
Baseline, 3 months and 6 months post-intervention
|
|
Concentration of Systemic Inflammatory Markers
Tidsramme: Baseline, 3 months and 6 months post-intervention
|
Circulating levels of specific systemic inflammatory mediators (specifically Interleukin-6 [IL-6] and Tumor Necrosis Factor-alpha [TNF-ɑ]) measured in blood samples using Enzyme-Linked Immunosorbent Assay (ELISA) to evaluate host-microbe signaling pathways.
The results data table will report the mean concentration in picograms per milliliter (pg/mL)
