Osteomyelitis

Staphylococcal osteoarticular infections (OAIs), including prosthetic joint infections and chronic osteomyelitis, represent a major cause of morbidity. Rifampicin is a key bactericidal antibiotic effective against staphylococcal biofilm. However, its pharmacokinetics exhibit substantial inter-individual variability due to complex hepatic metabolism and drug interactions. Currently, no prospective population pharmacokinetic (PopPK) model of rifampicin combined with levofloxacin or ciprofloxacin exists in patients with OAIs. Objectives: The primary objective of this study is to develop a population pharmacokinetic model of oral rifampicin in patients undergoing medico-surgical treatment for staphylococcal osteoarticular infections. Secondary objectives include evaluating the pharmacokinetics of the partner antibiotic (levofloxacin or ciprofloxacin), investigating the correlation between antibiotic exposure metrics (AUC, Cmax, AUC/MIC) and clinical/biological tolerance, and assessing 1-year infection relapse-free survival and resistance emergence. Study Design: Prospective, single-center, interventional study with minimal risks and constraints (RIPH 2) involving 40 participants recruited at the Reference Center for Complex Osteoarticular Infections (CRIOAC).

The purpose of this trial is to determine if genex with gentamicin (genex G) an antibiotic loaded bone void filler, works to treat and is a safe option as part of the surgical treatment of osteomyelitis in the extremities.

The ACHILLS Trial is a multicentre randomised controlled feasibility study comparing partial calcanectomy with and without the use of an antibiotic-impregnated bone graft substitute (Cerament G) for treating calcaneal osteomyelitis, specifically on wound healing rates, re-infection, and overall efficacy in a sample of 30 patients over a one-year period.

The purpose of this trial is to assess the safety, tolerability and between-group effect size of STIMULAN VG (with debridement) and a course of systemic antibiotics to standard of care (debridement and systemic antibiotics only) for the treatment of osteomyelitis associated stage IV pressure ulcers.

The study is a prospective cohort study of subjects where CERAMENT G was used as part of the surgical treatment of osteomyelitis in a single stage procedure.

This is a multi- centre trial of children with bone and joint infections (BJIs) at eight major paediatric hospitals in Australia and New Zealand. The primary objective is to establish if in children with acute, uncomplicated BJIs, entirely oral antibiotic treatment is not inferior to initial intravenous (IV) treatment for 1 to 7 days followed by an oral antibiotic course in achieving full recovery 3 months after presentation. Children will be randomly allocated to the 'entirely oral antibiotic' group or the 'standard treatment' group.

This study looks at how well one antibiotic (monotherapy) works compared to two antibiotics (combination therapy) in treating bone infections caused by Pseudomonas aeruginosa. It includes 300 adult patients who had this type of infection confirmed by lab tests and medical imaging. The goal is to find out if using just one antibiotic is as effective as using two, while also looking at side effects, the need for more surgery, antibiotic resistance, and overall antibiotic use.

This study evaluates the effect of additional hyperbaric oxygen therapy after lower extremity amputation. The patients will be randomized after amputation to either a treatment group receiving hyperbaric oxygen therapy, or control group.

The purpose of this European, multicentric, prospective, non-interventional study is to document and evaluate the efficacy and safety of the treatment of severely infected patients with intravenously administered fosfomycin, including patients with osteomyelitis, complicated urinary tract infection, nosocomial lower respiratory tract infection, bacterial meningitis/central nervous system infection, bacteraemia/sepsis, skin and soft tissue infection, endocarditis or other infections, each as far as covered by the respective nationally relevant SmPC.

People with neuromotor disability (i.e. following an inborn or acquired spinal cord, cerebral or peripheral neurological lesion) are at high risk of osteomyelitis-associated pressure ulcers. The management of osteomyelitis-associated pressure ulcers is controversial. In our center, patients benefit from a one stage surgical management with bone shaving and flap covering osteitis of pressure ulcer to perform wound closing. Surgery is followed by an antibiotic treatment, secondarily adapted to intraoperative samples. The aim of this study is to describe the cohort and to identify factors associated with failure (or success) in this frail population.
