Insights
Recurrent urinary tract infections (UTIs) may have a genetic component. Identifying specific genes could help predict risk in adults and their children, improving UTI management.
Area of Science:
- Urology
- Genetics
- Immunology
Background:
- Urinary tract infections (UTIs) are common, affecting up to 50% of women and 10% of children, with 30-40% recurrence.
- Recurrent UTIs can lead to significant morbidity and frequent medication use.
- Emerging research suggests a genetic predisposition to recurrent UTIs.
Purpose of the Study:
- To investigate the potential genetic factors contributing to recurrent urinary tract infections.
- To identify specific genes associated with susceptibility to recurrent UTIs.
- To explore the implications of genetic components for diagnosing at-risk individuals and predicting familial risk.
Main Methods:
- Investigated 14 candidate genes for their association with recurrent UTIs in humans.
- Analyzed the potential role of specific genes in altering the host's response to UTIs.
Main Results:
- Six out of 14 investigated genes showed a potential association with recurrent UTI susceptibility.
- Genes such as HSPA1B, CXCR1 & 2, TLR2, TLR4, and TGF-beta1 appear linked to altered host responses in UTIs.
Conclusions:
- A genetic component may predispose individuals to recurrent urinary tract infections.
- Identifying these genetic markers could enable early diagnosis and risk prediction for recurrent UTIs.
- Further research into these genes can advance understanding and management of recurrent UTIs.
Abstract:
Urinary tract infections (UTIs) are a frequent cause of morbidity in children and adults and affect up to 10% of children; its recurrence rate is estimated at 30-40%. UTI may occur in up to 50% of all women in their lifetimes and frequently require medication. Recent advances have suggested that a deregulation of candidate genes in humans may predispose patients to recurrent UTI. The identification of a genetic component of UTI recurrences will make it possible to diagnose at-risk adults and to predict genetic recurrences in their offspring. Six out of 14 genes investigated in humans may be associated with susceptibility to recurrent UTI in humans. In particular, the HSPA1B, CXCR1 & 2, TLR2, TLR4, TGF-beta1 genes seem to be associated with an alteration of the host response to UTIs at various levels.
