Local Antibiotic Delivery for Prevention of Biomaterial Infection 

Opponent is Professor Chris Arts from Holland.

 

Orthopaedic infections, especially in combination with implants, remain a major clinical challenge. Elimination of bacteria is difficult due to the formation of a biofilm on implants, which limits the efficacy of antibiotics. Treatment requires high doses of antibiotics to achieve sufficient local concentration, which increases the risk of side effects. Challenges remain with limited local release of antibiotics, resulting in low tissue concentrations, promoting bacterial resistance and increasing the risk of recurrence. 

 

The thesis, which consists of 4 studies, shows that with a new carrier technology, antibiotics can be added to the bone mineral apatite and early infection be prevented. Furthermore, local apatite implants can recruit and bind certain systemically administered antibiotics and continue to provide protection against infection. Both early infection control and long-term protection can thereby be achieved. 

 

Lund/Malmö has a long tradition as a centre for treatment of bone and joint infections. The research was initially focused on tuberculosis, which was the most common bone infection until the 60s. With the introduction of artificial joints in 1970, registries and randomized studies from Lund regarding antibiotic prophylaxis had a major global impact. The model for collaboration with infection and orthopaedic specialists started in Lund in 1972 and has laid the foundation for modern treatment of orthopaedic infections.
