CORset Versus OstéoSynthese in Adult Pyogenic Spondylodiscitis
SpondylodiscitisPyogenic spondylitis in adults is usually treated by antibiotics according to bacteria evidenced in a diagnostic intervertebral disc puncture. Brace treatment is associated in patients presenting back pain and a risk for vertebral body collapse due to infection with subsequent kyphotic deformity of the thoracolumbar spine. Percutaneous minimally invasive posterior spinal instrumentation has evolved over the last decade and indications in infections arouse over the last years. This procedure is interesting as it is performed through small skin incisions only. It avoids paravertebral muscle dissection and thus limits intraoperative bleeding and access morbidity. Recent retrospective data suggests that this internal fixation represents a theoretical advantage over brace treatment by lowering back pain and increasing patient's quality of life in the short run, up to 3 months, but no randomized study was published. The patient's autonomy, including walking ability and daily activities, might improve more rapidly after a percutaneous procedure. Additionally, the sagittal alignment of the thoracolumbar spine could be better maintained by internal fixation, which might prevent progression into kyphosis and improve long-term outcome. The hypothesis is the superiority of percutaneous minimally invasive instrumentation on brace treatment in term of quality of life, back pain and quality of osseous healing.
Gene Expression Profiles in Spinal Tuberculosis.
TuberculosisSpinal15 moreTuberculosis (TB) is one of the top ten causes of death worldwide with approximately 10 million cases globally and 1.2 million deaths. Sub-Saharan Africa carries the highest burden of TB. South Africa has one of the highest HIV and TB rates worldwide with an HIV prevalence rate in adults of 19% and a TB case notification rate of 615/100,000 in 2019. Over many years, focus has been paid to pulmonary TB and extrapulmonary TB (EPTB) has received only little attention even though it accounts for almost a quatre of all TB cases. The diagnosis of EPTB remains challenging simply because sample collection requires invasive procedures in the absence of a blood-based diagnostic test. Spinal TB (spondylitis or spondylodiscitis caused by Mycobacterium tuberculosis) - often known as Pott's disease - accounts for up to 10% of EPTB and affects young children, people with HIV-coinfection and elderly, and often leads to lifelong debilitating disease due to devastating deformation of the spine and compression of neural structures. Little is known with regards to the extent of disease and isolated TB spine as well as a disseminated form of TB spine have been described. The latter presents with a spinal manifestation plus disseminations to other organs such as the lungs, pleura, lymph nodes, the GIT or urinary tract or even the brain. In the Spinal TB X cohort, the investigators aim to describe the clinical phenotype of spinal TB using whole body PET/CT and identify a specific gene expression profile for the different stages of dissemination and compare findings to previously described signatures for latent and active pulmonary TB. A blood-based test for spinal TB would lead to earlier diagnosis and treatment in all settings globally and improve treatment outcome of this devastating disease.
T2MR PCR Detection of ESKAPE Pathogens in Patients With Pyogenic Spondylodiscitis and Infective...
Osteomyelitis; VertebraEndocarditis1 moreOur prospective observational study focuses on the rapid detection of etiologic agents of pyogenic spondylodiscitis and infective endocarditis using the T2 Bacteria Panel (T2Biosystems). This diagnostic method combines polymerase chain reaction (PCR) and T2 magnetic resonance for detection of bacterial DNA from whole blood samples. It detects six pathogens known by the acronym ESKAPE (E. coli, S. aureus, K. pneumoniae, A. baumannii, P. aeruginosa, and E. faecium). In recent years, similar studies using the Bacteria Panel and Candida Panel have been performed in patients with bloodstream infections, leaving us with optimistic results.The aim of this study is to verify whether T2B can identify the etiologic agents of localized infections, specifically spondylodiscitis and endocarditis, with better sensitivity and specificity and shorter time to result compared to conventional diagnostics from blood culture. Rapid detection of pathogen may reduce time to targeted pathogen-specific antibiotic therapy and subsequently improve outcomes, shorten the treatment and contribute to slowing the development of antibiotic resistance.
Spondylodiscitis Cases at Assiut University Hospital
SpondylodiscitisThe term Spondylodiscitis (SD) involves infection of the vertebra (Spondylitis), infection of the intervertebral disc (Discitis), or both (Spondylodiscitis) Spondylodiscitis is a rare disease accounting for 2.7% of all cases of pyogenic osteomyelitis, with incidence varying from 1 per 100,000/year to 1 per 250,000/year However, there is evidence that the incidence is rising due to longer life expectancy for patients with increasing incidence of chronic debilitating disease including diabetes mellitus, malignancies ,(Human Immunodeficiency Virus (HIV)/ Acquired Immunodeficiency Syndrome (AIDs) , immunosuppressive therapy, increasing numbers of Intravenous drug users , and spinal surgeries. Pathogens can reach the spine either by: hematogenous spread, direct external inoculation, or spread from contiguous tissues harboring these pathogens. The hematogenous route is the predominant one, allowing seeding of infection from distant sites into the vertebral column. Since spondylodiscitis has not been studied in a clinical trial at our hospital, and information about this disease has come from retrospective case series and isolated cases. In this study, we present our prospectively collected patient clinical and epidemiological data in order to provide a proper management
Unilateral Posterolateral Approach for Spondylodiskitis
DiscitisThis retrospective study assess the efficacy and safety of a posterolateral unilateral approach for debridement and titanium cage insertion supplemented by contralateral transfascial screw fixation for sick patients suffering from septic thoracolumbosacral spondylodiskitis. Hematogenous pyogenic spondylodiskitis requires surgical intervention in cases of development of neurological signs, spinal instability, progressive spinal deformity and abscess. When operative treatment is indicated, an anterior approach by open thoracotomy or by a thoraco-abdominal approach or combined anterior and posterior approaches are recommended. In cases of severe sick patients anterior approach is associated with high morbidity and mortality.
Comparison of Two Antimicrobial Therapy Duration for Spondylodiscitis
Vertebral OsteomyelitisDuration of antimicrobial therapy for spondylodiscitis is not standardized; it could vary from 6 weeks to several months depending on the medical habits. The study hypothesis is that a 6 weeks antimicrobial therapy is not inferior to a 12 weeks. We run a prospective multi-centric, non inferiority open label trial, randomised in two parallel groups. The main objective is to compare the efficacy of two durations of antibiotherapy, 6 weeks versus 12 weeks, on the rate of cure in this indication. The study concerns 400 patients more than 18 years, 70 centres in France are involved. The duration of the study is 4 years.
Percutaneous Fluoroscopic vs CT Guided Core Needle Biopsy for Spinal Infection and Tumor
SpondylodiskitisSpinal TumorSpinal biopsy is important to obtain culture and histopathological diagnosis in spine infection and tumors. To date, there is no prospective randomized study comparing both techniques. Therefore, the aim of this prospective randomized trial was to evaluate the accuracy, safety and diagnostic outcome of both these techniques.A prospective randomized trial was performed in 60 patients divided equally into fluoroscopic and CT guided spinal biopsy groups. Transpedicular approach was done with 8G core biopsy needle. Specimens were sent for histopathological examinations and cultures. Diagnosis were made based on biopsy results, clinical criteria and disease progression during 6 months follow up. Radiation expose to patients and doctors were measured with optically stimulated luminescence dosimeters (OSLDs).
Conservative Versus Surgical Treatment of Native Vertebral Osteomyelitis
Vertebral OsteomyelitisSpondylodiscitis2 moreThe optimal treatment of uncomplicated native vertebral osteomyelitis (NVO) is unknown. While some authors recommend surgical treatment (consisting of spinal debridement, decompression and instrumentation using hardware implantation of hardware), others recommend conservative treatment (with antimicrobial therapy alone). In the proposed randomized controlled multicentric trial, we plan to compare the outcome of conservative vs, surgical treatment of NVO regarding (i) infection outcome (i.e. infection-free proportion of subjects), (ii) functional outcome (pain intensity, spine scores, general mobility, quality of life evaluation), and (iii) socioeconomic impact (direct and indirect costs due to NVO). A total of 350 subjects will be screened, 300 subjects will be randomized 1:1 into 2 arms: experimental (surgical treatment) and control (conservative treatment). Subjects in both groups will receive pathogen-directed antimicrobial therapy for 6 weeks. Excluded will be patients with acute neurologic impairment, extensive bone destruction, epidural/intraspinal abscess and with spinal hardware. The clinical impact of this study is enormous since it will generate evidence for rational treatment guidelines. We hypothesize that the conservative treatment of uncomplicated NVO is non-inferior to surgical therapy regarding infection outcome. If the conservative treatment of NVO demonstrate non-inferiority, patients may benefit from avoiding unnecessary surgical intervention.
The Value of PET/CT in Diagnosing Residual Disease in Patients With Spinal Infection
SpondylodiscitisMRI has shoved little correlation with the clinical finding during treatment of spondylodiscitis (infection in the vertebrae and/or discs). Since PET/CT is almost as good as MRI in diagnosing spondylodiscitis the hypothesis and this study is that PET/CT is better in predicting residual disease in patients with spondylodiscitis. Preliminary study.
Subclinical Propionibacterium Acnes Infection Estimation in the Intervertebral Disc (SPInE-ID)
InfectionIntervertebral Disc Herniation3 moreSubclinical infection of the intervertebral disc after lumbar disc herniation surgery has been correlated to chronic low back pain and vertebral endplate changes. The most commonly reported agent is Propionibacterium acnes. However, the real incidence is unclear, as it has been reported in some series ranging from 3.7% to 46%. Recently, a systematic review concluded that there is a relationship between P. acnes and endplate changes, but, there are so far no studies to verify whether the reported presence of that pathogen in the intervertebral discs is due to local infection or whether intraoperative contamination occurred during the collection of samples. Thus, the main objective of this study is to estimate the incidence of subclinical infection in patients surgically treated for lumbar disc herniation. To this end, a prospective cohort study will be conducted with a minimum of 95 patients between 18 and 65 years of age who have been submitted to surgery after failure of conservative treatment. The extruded disc will be removed and cultured for bacterial identification. As controls, the ligamentum flavum and the multifidus muscle, taken respectively before and after removal of the herniated fragment will also be cultured. Patients will be followed-up for a year and MRI will be done at the end of this period.
