Endometriosis, a prevalent yet painful condition, often poses diagnostic challenges, sometimes taking years to identify. However, a recent study by a team of U.S. researchers suggests that a stool test could facilitate quicker and easier diagnosis of this condition.
Published in the journal Med, the research indicates that women with endometriosis exhibit notable differences in their gut microbiomes compared to those without the disease. Dr. Rama Kommagani, an associate professor at Baylor College of Medicine and corresponding author of the study, explained, “Endometriosis occurs when tissue similar to the lining of the uterus grows outside its normal location, such as on the surrounding intestine or the abdominal cavity’s lining. This aberrant growth typically leads to symptoms such as pain, inflammation, bleeding, and infertility.” He added that the average time to accurately diagnose endometriosis is approximately seven years, with many initial misdiagnoses pointing to bowel issues.
Currently, the diagnosis of endometriosis requires surgical intervention, which often coincides with treatment. Dr. Kommagani noted, “Our earlier research on mice has demonstrated that the microbiome—composed of the bacteria in the body—and their metabolites can play a role in the progression of endometriosis.” In the latest study, the team analyzed stool samples from 18 women diagnosed with endometriosis and 31 healthy women, uncovering significant disparities in bacterial composition and metabolite profiles.
The researchers identified a specific combination of metabolites unique to those with endometriosis, resembling profiles found in patients with inflammatory bowel disease. Notably, one compound, 4-hydroxyindole, emerged as a strong indicator of the condition. Dr. Chandni Talwar, the study’s first author and a postdoctoral associate at Baylor, highlighted, “This compound, produced by beneficial bacteria, was found in lower quantities in women with endometriosis compared to those without.”
Dr. Talwar further stated, “Previous studies on animal models have linked specific bacterial metabolite signatures to endometriosis. Our research is pioneering in identifying a unique metabolite profile associated with human endometriosis, enhancing our understanding of the condition and potentially leading to improved management strategies.”
In their experiments, the team administered 4-hydroxyindole to mice, observing its ability to prevent the onset or progression of endometriosis-like inflammation. “These findings are very exciting,” Dr. Talwar concluded, indicating a promising direction for future research and diagnostic techniques.
