Investigating the Interplay between the Gut Microbiota and Host Immunity in Gastroenteric Disorders: The Potential of Combined Drug Therapies to Restore Microbial-immune Homeostasis.
Qiao Y & Gao X • Iranian journal of allergy, asthma, and immunology • 2026
Combination drug therapy demonstrated superior efficacy over monotherapy and control in enhancing gut microbial diversity, reducing inflammatory indices, shifting immune phenotype, and improving symptom severity in patients with moderate to severe gastrointestinal disorders over 12 weeks.
Key Findings
Results
Combination therapy demonstrated superior efficacy in enhancing gut microbial diversity compared to monotherapy and control groups.
Retrospective, observational study of 100 patients with moderate to severe gastrointestinal disorders
Conditions included irritable bowel syndrome and inflammatory bowel disease
Three groups were compared: control, monotherapy, and combination therapy
Study duration was 12 weeks
Improvements were observed in alpha diversity metrics
Results
Combination therapy was associated with a decrease in inflammatory indices in patients with gastroenteric disorders.
Inflammatory indices were measured across control, monotherapy, and combination therapy groups
The combination therapy group showed greater reductions in inflammatory markers compared to other groups
The study involved 100 patients over a 12-week observation period
Results
Combination therapy produced a shift in immune phenotype in patients with gastrointestinal disorders.
Immune phenotype changes were observed alongside microbial diversity improvements
The combination therapy group had better immune responses compared with the monotherapy and control groups
Changes in immune phenotype were part of the broader microbial-immune homeostasis restoration
Results
Patients receiving combination therapy experienced significant improvements in symptom severity, pain, and general health.
Outcomes measured included symptom severity, pain, and general health
The combination therapy group had better responses compared with the other groups
Improvements were observed across the 12-week treatment period in 100 patients
Results
Regression analysis revealed that microbial diversity, immune system regulation, and inflammation had positive effects on disease symptom alleviation.
Regression analysis was used to identify factors contributing to symptom improvement
Three key factors identified: microbial diversity, immune system regulation, and inflammation
These factors were found to have positive effects on disease symptom alleviation
Findings support combination therapy as a more comprehensive treatment approach for gastroenteric diseases
