Brief Summary

This pilot randomized controlled trial tested the feasibility of yoghurt supplementation (400 mL/day for 3 days) in critically ill adults receiving nasogastric feeds. Twelve patients were enrolled, with high adherence and no safety concerns reported. Yoghurt intake was associated with a significant reduction in systemic inflammation markers, particularly the neutrophil-to-lymphocyte ratio (NLR), and modest shifts in gut microbiome composition. Beneficial commensals such as Lactiplantibacillus plantarum and Bifidobacterium adolescentis were enriched, while opportunistic pathogens like Klebsiella pneumoniae and Clostridioides difficile were depleted. Microbial network analysis revealed increased connectivity and stability in the yoghurt group. Overall, yoghurt supplementation was feasible, safe, and showed preliminary biological signals of modulating inflammation and microbial ecology, supporting the rationale for a larger multicentre trial.

Outcome Measures

Primary Outcomes (1)

  • Change in neutrophil-to-lymphocyte ratio (NLR) from baseline to post-intervention

    NLR is a widely used marker of systemic inflammation in critically ill patients. The primary outcome is the change in NLR between baseline and post-intervention in the yoghurt-supplemented group compared with the control group.

    Baseline and after 3 days of intervention

Secondary Outcomes (3)

  • Change in albumin-globulin (A/G) ratio

    Baseline and after 3 days of intervention

  • Changes in gut microbiome composition and diversity

    Baseline and after 3 days of intervention

  • Microbial network connectivity and host-microbe associations

    Baseline and after 3 days of intervention

Study Arms (2)

Yoghurt Supplementation with Standard Feeding

EXPERIMENTAL

Participants receive standard nasogastric enteral feeding supplemented with 400 mL/day of plain yoghurt (OMFED, Bhubaneswar, India) administered once daily for three consecutive days. The intervention is designed to evaluate feasibility, safety, and preliminary effects on systemic inflammation and gut microbiome composition in critically ill adults.

Dietary Supplement: Yoghurt

Standard Feeding without Yoghurt

NO INTERVENTION

Participants receive standard nasogastric enteral feeding alone, without yoghurt supplementation. This control arm allows comparison of systemic inflammatory markers and gut microbiome changes relative to the yoghurt-supplemented group.

Interventions

YoghurtDIETARY_SUPPLEMENT

Participants receive standard nasogastric enteral feeding supplemented with 400 mL/day of plain yoghurt (OMFED, Bhubaneswar, India) administered once daily for three consecutive days. The intervention is designed to assess feasibility, safety, and preliminary effects on systemic inflammation and gut microbiome composition in critically ill adults.

Model Details: This was a single-centre, double-blind, randomized controlled pilot trial with two parallel arms. Critically ill adults receiving nasogastric feeds were assigned to either standard feeding plus yoghurt supplementation (400 mL/day for 3 days) or standard feeding alone. Randomization was computer-generated, and blinding was maintained for participants, investigators, and laboratory staff.
