Spectrum of Bacterial Infections in Rheumatology

Overview

Retrospective study of patients with a proved non-tuberculous osteoarticular infection (OAI) diagnosed in a rheumatology department during the years 2010-2020. The objectives are : – To describe sites, type of micro-organism, clinical data, origin of infection, therapeutic modalities et outcome – To compare OAI of urinary origin with those with another origin

Full Title of Study: “Spectrum of Bacterial Infections in Rheumatology and the Role of Urinary Tract Infection”

Study Type

  • Study Type: Observational
  • Study Design
    • Time Perspective: Retrospective
  • Study Primary Completion Date: December 31, 2021

Detailed Description

This retrospective study will be conducted on medical files. Patients will be mainly selected on : – A proved osteoarticular infection (OAI) diagnosed in the department of rheumatology of the René Dubos hospital from 1° January 2010 to 31 December 2020. – Adult patients 18 year's old or older – Infection proved by positive culture in the osteoarticular site and/or blood (with typical clinical and imaging features) The followed OAI are not included : – Infection on prosthetic joint, materiel ; post-operative OAI ; osteomyelitis – Brucellosis ; Lyme disease Patients are selected from the codification of the hospitalization ; medical files are reviewed by the investigators. OAI of urinary origin is defined either by the same micro-organism in urine and osteo-articular sample (or blood) or a bacteria in the osteo-articular sample in conjunction with : urologic pathology, recurrent urinary tract infection, urologic surgery, antibiotic therapy. – Characteristics of three populations will be compared : – – OAI of urinary origin – – OAI of another origin (skin, etc) – – OAI without known origin Characteristics include : gender, age, risk factors, site of osteo-articular infection, type of micro-organism, type of positive sample(s), blood cultures, urinary cultures, duration of symptoms, site of primary infection and/or type of contamination, biological results, echocardiography, imaging results, type of treatment (medical, surgical), outcome, duration of hospitalization, intensive unit care stay, death at hospital.

Interventions

  • Other: Groups/Cohortes
    • Retrospective study on medical file of patients with osteoarticular infections diagnose (date of the positive bacteriological sample) between January 1, 2010 and December 31, 2020

Arms, Groups and Cohorts

  • Osteoarticular infections
    • Retrospective study on medical file of patients with osteoarticular infections diagnose (date of the positive bacteriological sample) between January 1, 2010 and December 31, 2020

Clinical Trial Outcome Measures

Primary Measures

  • Identification of the spectrum of osteoarticular infections in adult, in a rheumatology department
    • Time Frame: Through study completion, an average of 1 year
    • The purpose of this database is to describe the spectrum of osteoarticular infections in adults, non-tuberculosis germs, in a rheumatology department of a CHG during the 2010s

Secondary Measures

  • Prevalence of urinary origin in osteoarticular infections in adults, compared with other origins
    • Time Frame: Through study completion, an average of 1 year
    • The second purpose of this database is to identify the characteristics of osteo-articular infections of urinary origin
