FRIDAY, Jan. 13, 2023 (HealthDay News) — Overuse of antibiotics may trigger inflammatory bowel disease (IBD), latest research suggests.
Amongst folks who were 40 or older, a latest study found that antibiotics may increase the danger for bowel diseases, akin to Crohn’s and ulcerative colitis, for one to 2 years after use. And the best risk was posed by two classes of antibiotics — nitroimidazoles and fluoroquinolones — often used to treat gut infections.
The researchers said these drugs indiscriminately goal all bacteria, not only those who cause disease.
“Antibiotics may impact the event of IBD through alteration of the microbiome,” said lead researcher Dr. Adam Faye. He’s an assistant professor at Latest York University’s Grossman School of Medicine, in Latest York City.
To cut back your risk for IBD, Faye advises using antibiotics only when needed and never for viral diseases akin to colds, flu or other respiratory and gastrointestinal illness.
“We would like patients to enhance quickly, so we could also be more apt to prescribe an antibiotic in a few of these settings, but along with exacerbating bacterial resistance patterns, that is one more reason to practice antibiotic stewardship,” Faye said. “In other words, use antibiotics when needed, but be cautious about prescribing them for an infection that may likely be self-limiting or is more likely viral.”
Overuse of antibiotics can alter the bacterial balance within the gut, called the microbiome, with serious consequences, Faye warned.
This study, nevertheless, doesn’t prove that antibiotics cause inflammatory bowel disease, only that there appears to be a connection.
For the study, Faye’s team used a Danish national medical database from 2000 to 2018 of greater than 6.1 million Danes who had not been diagnosed with IBD. In all, 91% were prescribed no less than one course of antibiotics in the course of the study period.
From 2000 to 2018, greater than 36,000 people were diagnosed with ulcerative colitis and nearly 17,000 with Crohn’s disease.
Faye’s team found that amongst individuals who had taken antibiotics, those between 10 and 40 years of age were 28% more prone to be diagnosed with IBD, as were 48% of 40- to 60-year-olds, and 47% of those of their 60s or older.
The chance was slightly higher for Crohn’s disease than for ulcerative colitis: 40% amongst those aged 10 to 40; 62% amongst 40- to 60-year-olds; and 51% amongst those of their 60s or older.
The researchers noted that the danger rose with each course of antibiotics — adding 11% to the danger for the youngest group, and 14% for the oldest.
Those that took five or more courses of antibiotics had the very best risk of developing an IBD: For those aged 10 to 40, risk jumped 69%. It doubled for those between 40 and 60, and was 95% higher for those of their 60s or older.
How much time had passed since taking antibiotics was also an element. It was as much as 66% higher in the primary two years, dropping to as little as 13% after 4 or five years.
Dr. Bethany DeVito, associate chief of ambulatory clinical gastroenterology at Northwell Health in Great Neck, N.Y., noted that the gut microbiome could be very complex.
“Any alterations within the microbiome can result in diseases in, especially, the GI tract with irritable bowel syndrome,” she said, after reviewing the findings. “There’s discuss it being a consider causing inflammatory bowel disease, due to the inflammation that may come about from altering the microbiome.”
Antibiotics can alter the microbiome and cause diarrhea, gas and bloating. So, DeVito said, the link with IBD shouldn’t be surprising.
“Only use antibiotics if you have got a transparent indication for it,” she advised. “Many patients want antibiotics for all kinds of illnesses and doctors may find it hard to withstand prescribing them.”
These requests might be annoying, and doctors must hold their ground and say no, DeVito said.
“Everyone’s on the lookout for a magic pill without realizing that there are consequences to that magic,” she said.
The study was published online Jan. 9 within the journal Gut.
