The Association between Modulating Inflammatory Cytokines and Constipation of Geriatrics in Iran

Area of Science:

• Gastroenterology
• Immunology
• Geriatrics

Background:

• The relationship between intestinal microbiota and constipation is debated, particularly in the elderly population.
• Constipation is a common condition among older adults, necessitating research into its underlying mechanisms.

Purpose of the Study:

• To investigate the role of modulating inflammatory cytokines in elderly patients experiencing constipation.
• To evaluate serum levels of tumor necrosis factor alpha (TNF-α), interleukin-1 (IL-1), and interleukin-6 (IL-6) in relation to constipation in the aged.

Main Methods:

• A case-control study involving 100 participants aged 65 years and above, divided into functional constipation (case) and control groups (50 each) based on ROME III criteria.
• Comparison of baseline demographic, clinical characteristics, and serum levels of TNF-α, IL-1, and IL-6 between the groups.
• Statistical analysis using independent t-tests and Chi-square tests.

Main Results:

• Significantly higher mean serum levels of TNF-α, IL-1, and IL-6 were observed in the constipation group compared to the control group (p < 0.001 for all).
• A reverse correlation between aging and TNF-α/IL-1 levels was noted in controls, while a direct correlation between aging and TNF-α/IL-6 levels was found in the constipation group.
• These findings suggest a complex interplay between aging, inflammatory cytokines, and constipation.

Conclusions:

• A significant association exists between serum levels of inflammatory cytokines and age-related constipation in the studied Iranian population.
• The gut microbiota's diversity and abundance may influence serum inflammatory cytokine levels, potentially contributing to constipation in the elderly.
• Further research is warranted to elucidate the specific role of gut microbial diversity and abundance in this context.
