Hope for enhanced UTI treatments to minimize bladder pain

January 29, 2020

Urinary tract infections (UTI's) are painful and usually short lived - but for millions of people this is simply not the case.

Low levels of infection can be found long after it's thought to have cleared, and research suggests this could be an unknown, but leading cause of chronic bladder dysfunction.

But the fight against pain, discomfort and a constant urge to urinate has taken a step forward with scientists identifying how the immune systems defence against bladder infection causes nerves to magnify the sensations felt by patients.

Flinders University researchers at SAHMRI in collaboration with Griffith University on the Gold Coast, have analysed how the immune system responds to urinary tract infections and the direct link this response has to magnifying bladder pain.

Clinical Pharmacology Research Fellow & Head of Bladder Research, Dr Luke Grundy, says understanding how nerves in the bladder transmit different sensations to the brain could potentially help limit bladder dysfunction in overactive bladder patients.

"We believe that chronic pain and bladder dysfunction are a failure of these nerves to reset after inflammation, so by understanding how these nerves function with a UTI and what causes them to become more sensitive over time, we can develop effective treatments."

"This is important, as many people diagnosed with an overactive bladder, a disorder that is currently considered to have no specific cause, have a history of urinary tract infections, and have been shown to have persistent low levels of UTI. This may lead to enhanced patient diagnosis and alternative treatment options for those suffering with an overactive bladder."

With the number of antibiotic resistant UTI's growing globally each year, many can no longer be treated with common antibiotics despite the fact one in every two women will develop a UTI in their lifetime.

Dr Grundy says this study provides new information into how UTI causes hypersensitivity of the nerves that carry sensation from the bladder to the brain, resulting in the symptoms of urinary frequency, urgency, and pelvic or suprapubic pain.

"Our study provides a new understanding of why some overactive bladder patients do not respond to traditional medications and continue to suffer in silence, and opens the door for the development of more specific and effective treatments in the future".

Chaired by two of Flinders University's renowned gut researchers, Professor Nick Spencer and Professor Stuart Brierley, a week long conference will delve into the latest gut / brain breakthroughs at the annual meeting of the Federation of Neurogastroenterology and Motility, from 24 to 28 March 2020.

The 4th Meeting of the Federation of NeuroGastroenterology and Motility is hosted by the Australasian NeuroGastro­enterology and Motility Association Inc, the American NeuroGastro­enterology and Motility Society, the Asian NeuroGastro­enterology and Motility Association, the European Society of Neurogastro­enterology and Motility, and the Latin-American Society of Neurogastroenterology.

What If?
There's plenty of speculation about what Donald Trump might do in the wake of the election. Would he dispute the results if he loses? Would he simply refuse to leave office, or even try to use the military to maintain control? Last summer, Rosa Brooks got together a team of experts and political operatives from both sides of the aisle to ask a slightly different question. Rather than arguing about whether he'd do those things, they dug into what exactly would happen if he did. Part war game part choose your own adventure, Rosa's Transition Integrity Project doesn't give us any predictions, and it isn't a referendum on Trump. Instead, it's a deeply illuminating stress test on our laws, our institutions, and on the commitment to democracy written into the constitution. This episode was reported by Bethel Habte, with help from Tracie Hunte, and produced by Bethel Habte. Jeremy Bloom provided original music.
