Drug Resistant Bacteria

Manuka honey could provide the key to a breakthrough treatment for cystic fibrosis patients following preliminary work by experts at Swansea University. Dr. Rowena Jenkins and Dr. Aled Roberts have found that using Manuka honey could offer an antibiotic alternative to treat antimicrobial resistant respiratory infections, particularly deadly bacteria found in Cystic Fibrosis (CF) infections.

Using lung tissue from pigs, experts treated grown bacterial infections mimicking those seen in CF patients with Manuka honey. The results showed that it was effective in killing antimicrobial resistant bacteria by 39% compared to 29% for antibiotics, whilst improving the activity of some antibiotics that were unable to function effectively by themselves, honey and antibiotics combined killed 90% of the bacteria tested.

Life threatening inherited diseases

CF is one of the UK’s most common life-threatening inherited diseases; so with around 10,400 people in the UK suffering according to the CF Trust. A government review led by Lord Jim O’Neill also highlighted the threat of antimicrobial resistance; so estimating that a continue rise in resistance by 2050 would lead to 10 million people dying every year from antimicrobial resistant infections.

A problem that CF patients suffer from are chronic and long-lasting respiratory infections; which often prove fatal due to the presence of certain bacteria; so that are resistant to many (if not all) the antibiotics that doctors currently have at their disposal. Bacteria that cannot be remove from the lungs through antibiotic treatment can; so as a last resort, be remove by providing patients with newly transplant lungs.

This has some associate risks, however, as the bacteria that cause the original infection can still be found in the upper airway; also migrate into the new lungs, thus making the transplant ineffective. Some patients have a worse prognosis as they are infect with deadly types of bacteria; so such as Pseudomonas and Burkholderia cepacia complex; which are difficult to kill (due to multiple antibiotic resistance) and cause extensive damage to the lungs.

Patient can prevent

In some instances, merely their presence within a patient; which can prevent them from receiving life saving lung transplants. The effectiveness of antibiotics against these deadly infections is a huge concern; so making the need to find suitable, non-toxic alternatives; which are effective at killing the bacteria a top priority.

Honey has been use for thousands of years as a medicinal product. More recently, research has shown that Manuka honey is capable of killing antibiotic resistant bacteria present in surface wounds. Funding from The Waterloo Foundation and The Hodge Foundation has allow research to look at it as an antibiotic alternative in CF infections.

The preliminary results are very promising and should these be replicate in the clinical setting then this could open up additional treatment options for those with cystic fibrosis infections. The synergy with antibiotics and absence of resistance seen in the laboratory has allow us to move into the current clinical trial, investigating the potential for Manuka honey as part of a sinus rinse for alleviating infection in the upper airway.
