Added value of [F]fluorodeoxyglucose positron emission tomography/computed tomography for the diagnosis of post-operative instrumented spine infection.

Purpose: Post-operative instrumented spine infection (PISI) is an infrequent complication. Diagnosis of spinal implant infection can be difficult, especially in case of chronic infection.

Methods: This retrospective study attempts to evaluate the diagnostic performance of [F]fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) in PISI.

Absence of Decline of Kidney Function in Human Immunodeficiency Virus-Infected Patients Under Routine Clinical Management.

Background: Since the introduction of antiretroviral therapy (ART), human immunodeficiency virus (HIV)-infected patients have a drastically improved prognosis but at the same time they are also more affected by non-HIV related complications, such as chronic kidney disease. The objective of our study was to investigate the effect of proteinuria and tenofovir (TDF)-containing ART regimens on the temporal evolution of estimated glomerular filtration rate (eGFR).

Methods: Between April 2008 and October 2012, we enrolled 395 patients with a complete renal evaluation among patients from the ANRS C03 Aquitaine cohort, a prospective hospital-based cohort of HIV-1-infected patients under routine clinical management in southwestern France.

Activation, senescence and inflammation markers in HIV patients: association with renal function.

Objectives: To assess the association among immune activation, immune senescence, inflammation biomarkers and renal function measured by estimated glomerular filtration rate (eGFR) at inclusion and its evolution over a 3-year follow-up in HIV-infected patients with undetectable viral load.

Design: The Chronic Immune Activation and Senescence (CIADIS) substudy consecutively included patients between October 2011 and May 2013 enrolled in the ANRS CO3 Aquitaine observational cohort.

Methods: Biomarkers of T-cell activation, differentiation and senescence were summarized in a cellular-CIADIS weighted score and inflammation biomarkers in a soluble-CIADIS weighted score using principal component analysis.

Interest of [(18)F]fluorodeoxyglucose positron emission tomography/computed tomography for the diagnosis of relapse in patients with spinal infection: a prospective study.

Relapse after treatment of a spinal infection is infrequent and difficult to diagnose. The aim of this study was to assess the diagnostic performance of [(18)F]fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) in this setting. Thirty patients (21 men, nine women; median age 61.
