The altered gut flora in obesity can also contribute to metabolic dysregulation and systemic inflammation. However, it remains unclear how dysregulation of systemic inflammation in obesity affects the gut microbiome. We hypothesized that colchicine’s systemic anti-inflammatory effects in obesity would be associated with improvements in gut microbial diversity. Methods: This study was a secondary analysis of a double-blind randomized placebo-controlled trial, in which 40 adults with obesity, high CRP (≥ 2.0 mg/L), insulin resistance (HOMA-IR ≥ 2.6 mg/L), and metabolic syndrome (MetS) were randomized to three months of colchicine 0.6mg or placebo tablets twice daily. Serum and stool samples were collected at baseline and final visit. Gut microbiota composition was characterized from stool DNA by dual-index amplification and sequencing of 16S ribosomal RNA. Results: Pre- and post-intervention stool samples were available for 15 colchicine- and 12 placebo-treated subjects. Circulating hsCRP, interleukin-6, resistin, white blood count, and neutrophils were significantly decreased in the colchicine arm as compared to placebo. However, changes in stool…
How strong is the evidence?
Evidence Hub reads this as a secondary / pooled analysis, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 40 participants or records.
