Up to 40% of patients with chronic back pain could be cured with a course of antibiotics rather than surgery. Surgeons in the UK and elsewhere are reviewing how they treat patients with chronic back pain after scientists discovered that many of the worst cases were due to bacterial infections. Many patients with unrelenting lower back pain will no longer face major operations but can instead be cured with courses of antibiotics costing around £114 (US$170).
One of the UK’s most eminent spinal surgeons said the discovery was the greatest he had witnessed in his professional life, and that its impact on medicine was worthy of a Nobel prize.
“This is vast. We are talking about probably half of all spinal surgery for back pain being replaced by taking antibiotics,” said Peter Hamlyn, a consultant neurological and spinal surgeon at University College London hospital.
The Danish team describe their work in two papers published in the European Spine Journal.
In the first report, they explain how bacterial infections inside slipped discs can cause painful inflammation and tiny fractures in the surrounding vertebrae. The Danish team examined tissue removed from patients for signs of infection. Nearly half tested positive, and of these, more than 80% carried bugs called Propionibacterium acnes. The microbes are better known for causing acne. They lurk around hair roots and in the crevices in our teeth, but can get into the bloodstream during tooth brushing. Normally they cause no harm, but the situation may change when a person suffers a slipped disc. To heal the damage, the body grows small blood vessels into the disc. Rather than helping, though, they ferry bacteria inside, where they grow and cause serious inflammation and damage to neighbouring vertebrae that shows up on an MRI scan.
The scientists proved they could cure chronic back pain with a 100-day course of antibiotics. In a randomised trial, the drugs reduced pain in 80% of patients who had suffered for more than six months and had signs of damaged vertebra under MRI scans.
Specialists who deal with back pain have long known that infections are sometimes to blame, but these cases were thought to be exceptional. That thinking has been overturned by scientists at the University of Southern Denmark who found that 20% to 40% of chronic lower back pain was caused by bacterial infections.
In Britain today, around 4 million people can expect to suffer from chronic lower back pain at some point in their lives. The latest work suggests that more than half a million of them would benefit from antibiotics.
This new procedure could save the UK nearly $500 million/year in medical costs and could save the US several billion per year.
