What Is the Diagnostic Accuracy of Alpha-Defensin and Leukocyte Esterase Test in Periprosthetic Shoulder Infection?

Clin Orthop Relat Res 2019 Apr 3. Epub 2019 Apr 3.

N. U. Ecker, A. Koniker, T. Gehrke, A. Zahar, M. Citak, Helios ENDO-Klinik Hamburg, Department of Orthopaedic Surgery, Hamburg, Germany A. Koniker, J. Salber, Ruhr-University Bochum, Department of General Surgery, Bochum, Germany M. Hentschke, MVZ Labor Dr. Fenner und Kollegen, Hamburg, Germany.

Background: The diagnosis of periprosthetic joint infection (PJI) after total shoulder arthroplasty (TSA) is challenging, especially in patients with Cutibacterium (formerly Propionibacterium) acnes infection. Despite the increasing number of patients with PJI of the shoulder, there are still no robust data regarding diagnostic tests in detecting shoulder PJI.

Questions/purposes: (1) What are the sensitivity, specificity, and negative- and positive-predictive values for the alpha-defensin enzyme-linked immunosorbent assay test in detecting PJI after TSA? (2) What are the diagnostic accuracies in detecting shoulder PJI for synovial alpha-defensin, leukocyte esterase Test, and serum C-reactive protein (CRP)?

Methods: All patients with painful TSA, who underwent joint aspiration to validate or exclude a PJI, between July 2015 and February 2018 were enrolled in this single-center study. Read More

Intervertebral disc penetration by antibiotics used prophylactically in spinal surgery: implications for the current standards and treatment of disc infections.

Eur Spine J 2019 Apr 1;28(4):783-791. Epub 2018 Dec 1.

Central European Institute of Technology (CEITEC), Masaryk University, Kamenice 753/5, 625 00, Brno, Czech Republic.

Purpose: The presence of Propionibacterium acnes in a substantial component of resected disc specimens obtained from patients undergoing discectomy or microdiscectomy has led to the suggestion that this prominent human skin and oral commensal may exacerbate the pathology of degenerative disc disease. This hypothesis, therefore, raises the exciting possibility that antibiotics could play an important role in treating this debilitating condition. To date, however, little information about antibiotic penetration into the intervertebral disc is available. Read More

Importance of Propionibacterium acnes hemolytic activity in human intervertebral discs: A microbiological study.

PLoS One 2018 29;13(11):e0208144. Epub 2018 Nov 29.

Central European Institute of Technology (CEITEC), Masaryk University, Brno, Czech Republic.

Most patients with chronic lower back pain (CLBP) exhibit degenerative disc disease. Disc specimens obtained during initial therapeutic discectomies are often infected/colonized with Propionibacterium acnes, a Gram-positive commensal of the human skin. Although pain associated with infection is typically ascribed to the body's inflammatory response, the Gram-positive bacterium Staphylococcus aureus was recently observed to directly activate nociceptors by secreting pore-forming α-hemolysins that disrupt neuronal cell membranes.

High prevalence of bacteria in clinically aseptic non-unions of the tibia and the femur in tissue biopsies.

Eur J Trauma Emerg Surg 2018 Sep 25. Epub 2018 Sep 25.

Department of Traumatology and Orthopedic Surgery, Cologne-Merheim Medical Center (CMMC), University Witten-Herdecke (UWH), Ostmerheimerstr. 200, 51109, Cologne, Germany.

Purpose: There are several hints that bacterial colonization might be an often overseen cause of non-union. Modern procedures like PCR have been reported to diagnose bacterial colonization with a high degree of accuracy. While PCR is not ubiquitously available, we hypothesize that biopsies from the non-union site are comparable to PCR results reported in the literature. Read More
