Summary
Urinary 3-indoxyl sulfate can indicate gut health after allogeneic stem cell transplant. This biomarker predicts lower risk of graft-versus-host disease and mortality, improving patient survival.
Area of Science:
- Hematology
- Microbiology
- Oncology
Background:
- Allogeneic hematopoietic stem cell transplantation (HSCT) is a life-saving procedure.
- Intestinal graft-versus-host disease (GVHD) and treatment-related mortality are significant complications following HSCT.
- The health of the intestinal microbiota plays a crucial role in HSCT outcomes.
Purpose of the Study:
- To identify a reliable biomarker for assessing intestinal microbiota health in the early post-HSCT period.
- To determine if this biomarker can predict clinical outcomes such as intestinal GVHD and mortality.
- To evaluate the association between the biomarker and overall survival after HSCT.
Main Methods:
- Prospective study involving patients undergoing allogeneic HSCT.
- Measurement of urinary 3-indoxyl sulfate levels within the first 10 days post-transplantation.
- Correlation analysis between urinary 3-indoxyl sulfate levels and clinical outcomes, including GVHD incidence, treatment-related mortality, and overall survival.
Main Results:
- Urinary 3-indoxyl sulfate levels serve as an early indicator of intestinal microbiota health.
- Elevated levels of urinary 3-indoxyl sulfate are associated with reduced incidence and severity of intestinal GVHD.
- Higher urinary 3-indoxyl sulfate levels correlate with decreased treatment-related mortality and improved overall survival.
Conclusions:
- Urinary 3-indoxyl sulfate is a promising, non-invasive biomarker for monitoring gut health post-allogeneic HSCT.
- This biomarker can aid in predicting and potentially mitigating adverse outcomes like GVHD and mortality.
- Monitoring urinary 3-indoxyl sulfate may facilitate personalized interventions to improve HSCT patient survival.

01:28Microbiota of the Urogenital Tract
38
The human urogenital system, once thought to be sterile in healthy individuals, is now recognized as a complex microbial habitat. Advancements in molecular sequencing techniques have revealed that even in healthy adults, the kidneys and bladder harbor microbial populations similar to those found in the distal urethra, albeit in much lower abundance. These resident microorganisms, while generally innocuous, can become opportunistic pathogens under conditions that alter the urogenital...

Urinalysis is a widely used diagnostic test that analyzes urine's physical, chemical, and microscopic characteristics. Healthcare providers use it to detect and monitor various health conditions, including renal disease, urinary tract infections (UTIs), diabetes, and metabolic or systemic disorders.Components of UrinalysisUrinalysis consists of three primary components: physical, chemical, and microscopic examination. Each provides unique insights into the urine sample and, by extension, the...

01:22Introduction to the Human Microbiota
81
Microorganisms colonize various regions of the human body, including the mouth, nasal passages, throat, stomach, intestines, urogenital tract, and skin. The total number of microbial cells is estimated to range from 10¹³ to 10¹⁴—comparable to, or exceeding, the number of human somatic cells. This host–microbiome relationship has led to the conceptualization of humans as supraorganisms, wherein microbial communities perform vital roles in development, immunity,...

A urine culture and sensitivity test is a diagnostic procedure used to identify urinary tract bacterial infections and determine the most effective antibiotics for treatment. This test is generally preferred when a patient shows manifestations of a urinary tract infection, such as frequent or painful urination, cloudy or foul-smelling urine, or lower abdominal pain.Purpose of the TestThe primary goals of a urine culture and sensitivity test are to:Determine the specific bacteria causing the...

The large intestine hosts the most densely populated microbial ecosystem in the human body. This complex community primarily consists of anaerobic bacteria, with Bacillota (formerly Firmicutes) and Bacteroidota (formerly Bacteroidetes) as the predominant groups. The distribution of these microbes varies along different sections of the large intestine, influenced by local environmental factors such as oxygen availability and nutrient composition.The cecum, located at the beginning of the large...

The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...
