ABSTRACTDaptomycin is an attractive option for treating prosthetic joint infection, but the 6-mg/kg of body weight/day dose was linked to clinical failure and emergence of resistance. Using a methicillin-resistantStaphylococcus aureus(MRSA) knee prosthesis infection in rabbits, we studied the efficacies of high-dose daptomycin (22 mg/kg given intravenously [i.v.] once daily [o.d.]; equivalent to 8 mg/kg/day in humans) or vancomycin (60 mg/kg given intramuscularly [i.m.] twice daily [b.i.d.]), both either alone or with adjunctive rifampin (10 mg/kg i.m. b.i.d.). After partial knee replacement with a silicone implant, 107MRSA CFU was injected into the knees. Treatment started 7 days postinoculation and lasted 7 days. Positive cultures were screened for the emergence of mutant strains, defined as having 3-fold-increased MICs. Althoughin vivomean log10CFU/g of daptomycin-treated (4.23 ± 1.44;n= 12) or vancomycin-treated (4.63 ± 1.08;n= 12) crushed bone was significantly lower than that of controls (5.93 ± 1.15;n= 9) (P< 0.01), neither treatment sterilized bone (2/12 and 0/12 rabbits with sterile bone, respectively). Daptomycin mutant strains were found in 6/12, 3/12, and 2/9 daptomycin-treated, vancomycin-treated, and control rabbits, respectively; no resistant strains emerged (MIC was always <1 mg/liter). Adjunctive rifampin with daptomycin (1.47 ± 0.04 CFU/g of bone [detection threshold]; 11/11 sterile bones) or vancomycin (1.5 ± 0.12 CFU/g of bone; 6/8 sterile bones) was significantly more effective than monotherapy (P< 0.01) and prevented the emergence of daptomycin mutant strains. In this MRSA joint prosthesis infection model, combining rifampin with daptomycin was highly effective. Daptomycin mutant strains were isolatedin vivoeven without treatment, but adjunctive rifampin prevented this phenomenon, previously found after monotherapy in humans.

ABSTRACTThe empirical use of vancomycin in combination with a broad-spectrum beta-lactam is currently recommended after the initial surgery of prosthetic joint infection (PJI). However, the tolerability of such high-dose intravenous regimens is poorly known. Adult patients receiving an empirical antimicrobial therapy (EAT) for a PJI were enrolled in a prospective cohort study (2011 to 2016). EAT-related adverse events (AE) were described according to the common terminology criteria for AE (CTCAE), and their determinants were assessed by logistic regression and Kaplan-Meier curve analysis. The EAT of the 333 included patients (median age, 69.8 years; interquartile range [IQR], 59.3 to 79.1 years) mostly relies on vancomycin (n= 229, 68.8%), piperacillin-tazobactam (n= 131, 39.3%), and/or third-generation cephalosporins (n= 50, 15%). Forty-two patients (12.6%) experienced an EAT-related AE. Ten (20.4%) AE were severe (CTCAE grade ≥ 3). The use of vancomycin (odds ratio [OR], 6.9; 95% confidence interval [95%CI], 2.1 to 22.9), piperacillin-tazobactam (OR, 3.7; 95%CI, 1.8 to 7.2), or the combination of both (OR, 4.1; 95%CI, 2.1 to 8.2) were the only AE predictors. Acute kidney injury (AKI) was the most common AE (n= 25; 51.0% of AE) and was also associated with the use of the vancomycin and piperacillin-tazobactam combination (OR, 6.7; 95%CI, 2.6 to 17.3). A vancomycin plasma overexposure was noted in nine (37.5%) of the vancomycin-related AKIs only. Other vancomycin-based therapies were significantly less at risk for AE and AKI. The EAT of PJI is associated with an important rate of AE, linked with the use of the vancomycin and the piperacillin-tazobactam combination. These results corroborate recent findings suggesting a synergic toxicity of these drugs in comparison to vancomycin-cefepime, which remains to be evaluated in PJI.

Knee Joint Infection

Successful joint replacement is a life-enhancing procedure with significant growth in the past decade. Prosthetic joint infection occurs rarely; it is a biofilm-based infection that is poorly responsive to antibiotic alone. Recent interest in bacteriophage therapy has made it possible to treat some biofilm-based infections, as well as those caused by multidrug-resistant pathogens, successfully when conventional antibiotic therapy has failed. Here, we describe the case of a 61-year-old woman who was successfully treated after a second cycle of bacteriophage therapy administered at the time of a two-stage exchange procedure for a persistent methicillin-sensitive Staphylococcus aureus (MSSA) prosthetic knee-joint infection. We highlight the safety and efficacy of both intravenous and intra-articular infusions of bacteriophage therapy, a successful outcome with a single lytic phage, and the development of serum neutralization with prolonged treatment.

AbstractDiagnostic thresholds used to standardize the definition for prosthetic joint infection (PJI) have largely focused on total joint arthroplasty (TJA). Established PJI thresholds exist for serum erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) in TJA; however, they do not exist for revision hip hemiarthroplasty (rHHA). The purpose of this study was to establish thresholds for (1) ESR and (2) CRP to diagnose PJI in rHHA. Data were collected on a prospective cohort of 69 rHHA patients undergoing orthopaedic surgery between 1/2017 and 2/2019 in a single health care system. Procedures were categorized as septic or aseptic revisions using Musculoskeletal Infection Society (MSIS) criteria (2013). There were 44 ESRs (n = 28 aseptic, n = 16 septic) and 46 CRPs (n = 29 aseptic, n = 17 septic) available for analysis. Two tailed t-tests were performed to compare the mean ESR and CRP in aseptic and septic cases. Receiver operator characteristic (ROC) curves were generated to obtain diagnostic cutoff thresholds using the Youden's Index (J) for ESR and CRP. The mean ESR was 50.3 ± 30.6 mm/h versus 15.4 ± 17.7 mm/h (p < 0.001), while the mean CRP was 29.9 ± 24.8 mg/L versus 4.1 ± 8.2 mg/L (p < 0.001) for septic and aseptic revisions, respectively. The diagnostic threshold for PJI determined by the ROC curve was 44 mm/h for ESR (sensitivity = 56.3%; specificity = 100.0%; J = 0.563; area under the curve (AUC) = 0.845), while it was 12.5 mg/L for CRP (sensitivity = 70.6%; specificity = 96.6%; J = 0.672; AUC = 0.896). For patients with HHA, an ESR of 44 mm/h was and a CRP of 12.5 mg/L was highly specific for PJI. The thresholds are similar to the MSIS thresholds currently published. Larger prospective trials are needed to establish more robust and conclusive diagnostic criteria for PJI in HHA, including investigations not only of ESR and CRP but synovial white blood cell count and synovial polymorphonuclear leukocytes % as well.
