Coxiella Burnetii Endocarditis: Can Positron Emission Tomography be an Alternative to Diagnosis?

Marjorie Hayashida Mizuta et al. Cristhian Espinoza Romero Santiago Castro Vintimilla Tatiana de Carvalho Andreucci Torres Leal … Paulo Rogério Soares Alexandre de Matos Soeiro

Introduction

Coxiella burnetii infective endocarditis (IE) represents a rarely reported zoonosis in Brazil. It is estimated that Coxiella burnetii is responsible for up to 5% of all IE cases worldwide. The disease affects mostly valvulopathy patients and immunocompromised subjects.

Different from the classical acute and sub-acute endocarditis, the clinical picture is frustrating, and, because this is an obligate intracellular microorganism, hemocultures (HMC) are predominantly negative, which makes the clinical suspicion more difficult.

Molecular Imaging in the Diagnosis of Infectious Endocarditis – the Role of PET and SPECT

Domenico Albano et al. Francesco Bertagna Raffaele Giubbini

Abstract

18-fluorine-fluorodeoxyglucose positron emission computed tomography (18F-FDG PET/CT) and singlephoton emission computed tomography (SPECT) using radiolabeled white blood cells (WBC) are non-invasive techniques widely used in the diagnosis of infections, like endocarditis. The aim of our paper was to provide a systematic review of the published data on the use of 18F-FDG PET/CT and SPECT in infective endocarditis (IE). A comprehensive literature search of the PubMed/ MEDLINE, Scopus, Embase and Cochrane library databases was conducted to find relevant published articles about the diagnostic performance of SPECT using WBC and 18F-FDG PET/CT in the diagnosis of infectious endocarditis. Twenty papers were included, with a total of 1,154 patients (166 studies with WBC SPECT and 988 with 18F-FDG PET/CT). From the analyses of the studies, the following results were obtained: both SPECT and PET/CT had good diagnostic accuracy in the study of endocarditis. 18F-FDG PET/CT had good specificity (85.8%) and lower sensitivity (68%), with high heterogeneity among the studies; WBC SPECT/ CT had an overall sensitivity of 80% and specificity of 98%. Specific preparations for PET/CT can affect the diagnostic accuracy of the test. Both 18F-FDG PET/CT and WBC SPECT are useful for the diagnosis of IE, and WBC SPECT appears to be slightly more specific than 18F-FDG PET/CT. A specific diet could influence the diagnostic performance of PET/CT.
