[PMID: 38862277 DOI: 10.1016/j.surg.2024.04.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Revised: 04/04/2024] [Accepted: 04/22/2024] [Indexed: 06/13/2024]
Abstract
BACKGROUND Polymerase chain reaction is a method to detect bacterial DNA and is widely used because it delivers results within a few hours with the potential to guide postoperative antibiotic treatment. This study aims to determine if polymerase chain reaction can accurately detect bacteria in the peritoneal fluid compared with conventional culture from patients operated for acute appendicitis. METHODS This prospective cohort study included patients above the age of 18 years who underwent laparoscopic surgery for acute appendicitis. Peritoneal samples were collected before the appendectomy procedure for conventional culture and polymerase chain reaction using the BioFire Blood Culture Identification 2 Panel for comparison. During surgery, the surgeon assessed the appendicitis as either complicated or noncomplicated. RESULTS Samples from 102 patients were eligible for analysis. Twelve samples were polymerase chain reaction positive, and 14 samples were culture positive. The concordance of positive results when comparing these 2 methods was 71.4%. The most commonly found bacteria were Escherichia coli and Bacteroides fragilis. Of the 36 patients with complicated appendicitis, no bacteria were detected by either conventional culture or polymerase chain reaction in 21 (58%) of the patients. In patients with uncomplicated appendicitis, bacteria were demonstrated in 1 out of 66 (2%) patients. CONCLUSION This study suggests that polymerase chain reaction can be used to detect bacteria in the peritoneal fluid and has the potential to guide postoperative antibiotic treatment.

Abstract
The use of clinical molecular diagnostic methods for detecting microbial pathogens continues to expand and, in some cases, supplant conventional identification methods in various scenarios. Analytical and clinical benefits of multiplex molecular panels for the detection of respiratory pathogens have been demonstrated in various studies. The use of these panels in managing different patient populations has been incorporated into clinical guidance documents. The Association for Molecular Pathology's Infectious Diseases Multiplex Working Group conducted a review of the current benefits and challenges to using multiplex PCR for the detection of pathogens from gastrointestinal tract, central nervous system, lower respiratory tract, and joint specimens. The Working Group also discusses future directions and novel approaches to detection of pathogens in alternate specimen types, and outlines challenges associated with implementation of these multiplex PCR panels.

Evaluation and Clinical Impact of Biofire FilmArray Pneumonia Panel Plus in ICU-Hospitalized COVID-19 Patients. Diagnostics (Basel) 2022; 12:diagnostics12123134.

Abstract
Microbiological diagnosis by using commercial multiplex quantitative PCR systems provides great advantages over the conventional culture. In this work, the Biofire FilmArray Pneumonia Panel Plus (FAPP+) was used to test 144 low respiratory tract samples from 105 COVID-19 patients admitted to an Intensive Care Unit (ICU), detecting 78 pathogens in 59 (41%) samples. The molecular panel was evaluated by using the conventional culture (CC) as comparator, which isolated 42 pathogens in 40 (27.7%) samples. The overall percentage of agreement was 82.6%. Values of sensitivity (93%), specificity (62%), positive predictive value (50%), and negative predictive value (96%) were obtained. The mean time elapsed from sample extraction to modification of antibiotic treatment was 7.6 h. A change in antimicrobial treatment after the FAPP+ results was performed in 27% of patients. The FAPP+ is a highly sensitive diagnostic method that can be used to significantly reduce diagnostic time and that allows an early optimization of antimicrobial treatment.

Abstract
The recent development of commercial panel-based molecular diagnostics for the rapid detection of pathogens in positive blood culture bottles, respiratory specimens, stool, and cerebrospinal fluid has resulted in a paradigm shift in clinical microbiology and clinical practice. This review focuses on U.S. Food and Drug Administration (FDA)-approved/cleared multiplex molecular panels with more than five targets designed to assist in the diagnosis of bloodstream, respiratory tract, gastrointestinal, or central nervous system infections. While these panel-based assays have the clear advantages of a rapid turnaround time and the detection of a large number of microorganisms and promise to improve health care, they present certain challenges, including cost and the definition of ideal test utilization strategies (i.e., optimal ordering) and test interpretation.
