ABSTRACT

The incidence of spinal infections,a relatively rare infectious disease,is on the rise due to the empirical use of antibiotics that increases the chances of infection with drug-resistant bacteria,as well as advances in testing technology that have led to an increase in detection rates.Identifying the type of pathogen to target antibi-otics is the key to treatment.However,conventionaldetection methods have low detection rates and are time-consum-ing,which are not conducive to the rapid and accurate diagnosis of spinal infection.Metagenomics next-generation sequencing(mNGS)is a detection technique that can sequence all nucleic acid fragments in samples,the emer-gence of which subverts traditional detection methods and plays an important role in the diagnosis and treatment of spinal infections.This article summarizes the application of mNGS in the diagnosis and treatment of spinal infection.

ABSTRACT

Objective To explore the efficacy of T-cell spot test of tuberculosis infection(T-SPOT.TB)in the differential diagnosis of spinal tuberculosis(STB),and optimize diagnostic efficacy through the optimal cut-off value of receiver operating characteristic(ROC)curve.Methods Clinical data of patients with spinal infection in a hospi-tal from January 2010 to May 2019 were collected,including preoperative T-SPOT.TB test results,white blood cell count,C-reactive protein,erythrocyte sedimentation rate,procalcitonin,and tuberculosis antibodies,etal.Clinical diagnosis was conducted based on diagnostic criteria.The sensitivity and specificity of T-SPOT.TB in preoperative diagnosis of STB and other spinal infection was analyzed,and the diagnostic efficacy of the optimized T-SPOT.TB indicators was evaluated.Results A total of 132 patients were included in this study,out of whom 78 patients(59.09%)were diagnosed with STB,and 54(40.91%)were diagnosed with non-tuberculosis(non-TB)spinal in-fection.The sensitivity and specificity of T-SPOT.TB in differential diagnosis of STB were 67.68%and 66.67%,respectively.Univariate logistic regression analysis showed that compared with non-TB spinal infection,the OR va-lue of T-SPOT.TB test in diagnosing STB was 4.188(95%CI:1.847-9.974,P<0.001).The optimized T-SPOT.TB evaluation index through ROC curve to determine the optimal cut-off values of ESAT-6,CFP-10,and CFP-10+ESAT-6 for differential diagnosis of STB and non-TB spinal infection were 12.5,19.5,and 36,respec-tively,and area under curve(AUC)values were 0.765 6,0.741 5,and 0.778 6,respectively,all with good diag-nostic efficacy.CFP-10+ESAT-6 had the highest AUC.CFP-10+ESAT-6 specific spot count had higher efficacy in the diagnosis of STB,with a diagnostic accuracy of 75.56%,higher than 67.42%of pre-optimized T-SPOT.TB.Conclusion T-SPOT.TB test has high diagnostic efficacy in differentiating STB from non-TB spinal infection.Posi-tivity in T-SPOT.TB test,especially with spot count of CFP-10+ESAT-6 over 36,indicates a higher likelihood of STB.

ABSTRACT

Fundamento: La espondilodiscitis es un proceso infeccioso del cuerpo vertebral y del disco intervertebral. Presenta una etiología multifactorial y requiere un abordaje multidisciplinario. El menor número corresponde a la columna cervical. El tratamiento quirúrgico se sugiere en pacientes con defecto neurológico, deformidad y fallo de la terapia conservadora. Objetivo: Describir las características clínicas, radiológicas y el tratamiento quirúrgico de un paciente con espondilodiscitis cervical. Presentación del caso: Paciente masculino de 48 años con antecedentes de diabetes mellitus tipo 2. Presentó ántrax nucal y fue tratado con antimicrobianos. Al año volvió a consulta con entumecimiento en el brazo derecho, que luego se generalizó hacia las otras extremidades. Se diagnosticó espondilodiscitis cervical a nivel C6-C7. Se decidió aplicar tratamiento quirúrgico mediante corporectomia de C6 y C7, con injerto tricortical de cresta ilíaca, y colocar placa de titanio desde C5 a D1. Se aisló Staphylococcus aureus en el disco intervertebral, por lo cual se trató con antibiótico específico durante 6 semanas. Conclusiones: La espondilodiscitis cervical es la infección espinal de más baja incidencia. Su aparición tardía en un paciente inmunocompetente después de una infección de piel, resulta muy inusual. El manejo quirúrgico mediante descompresión y fijación con lámina y tornillos de titanio, junto con el tratamiento antibiótico, resultó en una excelente evolución posoperatoria.


Instroduction: Spondylodiscitis is an infectious process of the vertebral body and the intervertebral disc. It has multifactorial etiology which requires a multidisciplinary approach. The smallest number corresponds to the cervical spine. Surgical treatment is suggested in patients with neurological defect, deformity and failure of conservative therapy. Objective: To describe the clinical and radiological characteristics and the surgical treatment of a patient with cervical spondylodiscitis. Case report: We report the case of a 48-year-old male patient with a history of type II diabetes mellitus. He presented nuchal anthrax and he was treated with antimicrobials. A year later, he returned to the consultation with numbness in his right arm and later it spread to the other extremities. Cervical spondylodiscitis is diagnosed at C6-C7 level. It was decided to apply surgical treatment by C6 and C7 corporectomy with iliac crest tricortical graft and place a titanium plate from C5 to D1. Staphylococcus aureus was isolated from the intervertebral disc and specific antibiotic treatment was continued for 6 weeks. Conclusions: Cervical spondylodiscitis is the spinal infection with the lowest incidence. Its late appearance in an immunocompetent patient after a skin infection is highly unusual. Surgical management by means of decompression and fixation with blade and titanium screws, together with antibiotic treatment, resulted in an excellent postoperative evolution.

ABSTRACT

@#Abstract: To report a case of Aspergillus salwaensis-induced spinal infection and its laboratory detection. The inflammatory granulation and necrotic tissue samples of a patient with spinal infection were collected from, the Affiliated Hospital of Chengde Medical College on June 17, 2020 for direct smear microscopy and culture, and the isolated strain was identified by microscopy by smear staining, matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF-MS), molecular identification and in vitro antifungal susceptibility test. The patient was 62 years old female and presented with recurrent chest and back pain with no obvious cause. The initial diagnosis was spinal infection, after 7 days of treatment with levofloxacin, the effect was not good. Surgery was then performed remove the lesion via posterior thoracic debridement, and fungal hypha was observed under microscope in tissue specimens. The isolated strains had no typical structure, MALDI-TOF-MS was used for identification for many times, but there was no identification result. After 7 days of fluconazole treatment, the patient's condition improved, and her chest and back pain were alleviated compared to before surgery. The patient was discharged and followed up in the outpatient department, the fungus was later identified as Aspergillus salwaensis by sequence analysis of the internal transcribed spacer (ITS) gene sequencing, and the patient's antifungal medication was changed to voriconazole after with the attending physician. The patient consciously recovered well with no pain in the operative area and normal spinal activity at 1 year follow-up. The possibility of spinal fungal infection should be considered in patients with back pain without a clear cause and poor response to routine antibiotic treatment. Direct smear report of microscopic results are very important for guiding clinical antibiotic selection for rare filament fungi with atypical colony and microscopic morphology and unsuccessful MALDI-TOF-MS identification, molecular biological methods such as ITS sequence analysis can be helpful for early identification of the fungal species, improving identification speed.

ABSTRACT

Objective:To investigate the efficacy of metagenomic next generation sequencing (mNGS) in the etiological diagnosis of patients with spinal infection, so as to provide reference for timely diagnosis and treatment.Methods:A total of 40 patients with suspected spinal infection admitted to the Department of Infectious Diseases in Henan Provincial People′s Hospital from January 2020 to July 2022 were included. The results of tissue culture, histopathological examination and tissue mNGS detection were analyzed retrospectively. According to the clinical diagnose, the patients were divided into the spinal infection group (28 cases) and the non-spinal infection group (12 cases). The positive rate, sensitivity and specificity of mNGS and tissue culture in the pathogen detection of patients with spinal infection were compared. McNemar test was used for statistical analysis.Results:There were 23 males and 17 females in 40 patients. The positive rate of mNGS was higher than that of tissue culture (75.0%(30/40) vs 12.5%(5/40)), and the difference was statistically significant ( χ2=0.08, P<0.001). Based on clinical diagnostic criteria, the sensitivity of mNGS in the diagnosis of spinal infection was higher than that of tissue culture (82.1% vs 17.9%), with a statistically significant difference ( χ2=0.02, P<0.001), while the specificity compared to the tissue culture (33.3% vs 100.0%), the difference was not statistically significant ( P>0.05). Conclusions:mNGS has a high pathogen detection rate and sensitivity in the etiological diagnosis of patients with spinal infection, which could provide clinical guidance for the diagnosis and treatment of patients with spinal infection.

ABSTRACT

Postoperative infection from total knee arthroplasty (TKA) is an issue drawing great attention, which can manifest as a local or general infection. Its development into sepsis has also occasionally been reported. Such sepsis is a critical complication that can spread to various parts of the body, which can ultimately lead to mortality. However, the cases where infection has spread to the spine do not have clear clinical signs, making diagnosis difficult. These cases are not found in the literature. Therefore, this is a case study on both postoperative infection from TKA that has developed into sepsis and spread to the spine.

ABSTRACT

OBJECTIVE: Infectious spinal disease is regarded as an infection by a specific organism that affects the vertebral body, intervertebral disc and adjacent perivertebral soft tissue. Its incidence seems to be increasing as a result of larger proportion of the older patients with chronic debilitating disease, the rise of intravenous drug abuser, and the increase in spinal procedure and surgery. In Korea, studies assessing infectious spinal disease are rare and have not been addressed in recent times. The objectives of this study are to describe the epidemiology of all kind of spinal infectious disease and their clinical and microbiological characteristics as well as to assess the diagnostic methodology and the parameters related to the outcomes. METHODS: A retrospective study was performed in all infectious spinal disease cases presenting from January 2005 to April 2010 to three tertiary teaching hospitals within a city of 1.5 million in Korea. Patient demographics, risk factors, clinical features, and outcomes were assessed. Risk factors entailed the presence of diabetes, chronic renal failure, liver cirrhosis, immunosuppressants, remote infection, underlying malignancy and previous spinal surgery or procedure. We comparatively analyzed the results between the groups of pyogenic and tuberculous spinal infection. SPSS version 14 statistical software was used to perform the analyses of the data. The threshold for statistical significance was established at p<0.05. RESULTS: Ninety-two cases fulfilled the inclusion criteria and were reviewed. Overall, patients of tuberculous spinal infection (TSI) and pyogenic spinal infection (PSI) entailed 20 (21.7%) and 72 (78.3%) cases, respectively. A previous spinal surgery or procedure was the most commonly noted risk factor (39.1%), followed by diabetes (15.2%). The occurrence of both pyogenic and tuberculous spondylitis was predominant in the lumbar spine. Discs are more easily invaded in PSI. At initial presentation, white cell blood count and C-reactive protein levels were higher in PSI compared to TSI (p<0.05). Etiological agents were identified in 53.3%, and the most effective method for identification of etiological agents was tissue culture (50.0%). Staphyococcus aureus was the most commonly isolated infective agent associated with pyogenic spondylitis, followed by E. coli. Surgical treatment was performed in 31.5% of pyogenic spondylitis and in 35.0% of tuberculous spondylitis cases. CONCLUSION: Many previous studies in Korea usually reported that tuberculous spondylitis is the predominant infection. However, in our study, the number of pyogenic infection was 3 times greater than that of tuberculous spinal disease. Etiological agents were identified in a half of all infectious spinal disease. For better outcomes, we should try to identify the causative microorganism before antibiotic therapy and make every effort to improve the result of culture and biopsy.

ABSTRACT

OBJECTIVE: To study practical guidelines and strategies in the treatment of cervical osteomyelitis. METHODS: We retrospectively reviewed 14 patients who underwent surgical treatment for cervical osteomyelitis from May 2000 to July 2008. We investigated their clinical course, antibiotic regimen, surgical methods, and laboratory and radiologic findings including X-ray, CT and MRI. RESULTS: 5 patients had primary spondylodiscitis, 5 patients had post operative spondylodiscitis and 4 patients had tuberculosis in cervical spine. The causative microorganisms were MRSA (5), P. aeruginosa (1), Methicillin resistant coagulase negative streptococcus (1), P. aeruginosa changed to MRSA (1), and 2 patients showed no growth on culture studies. Patients were treated 13.8 weeks (range, 5.4-25.8) with IV antibiotics and then treated for 58.2 days (range, 13-106) with oral antibiotics. Antituberculotic medications were used for a mean of 383.8 days. Patients were treated with anterior debridement and fusion (5), irrigation and debridement (5), simultaneous cervical anterior interbody and transthoracic thoracic interbody fusion (1). 3 patients underwent the planned 2-staged operation, which included an anterior debridement with or without fusion for the 1st operation and posterior instrumentation for 2nd operation. 10 patients (71.4%) had neurologic deficits at the time of diagnosis and 7 patients (70%) among them improved post-operatively. CONCLUSION: Anterior cervical spine surgery is the preferable treatment option in patients with neurological deterioration, extensive bony destruction with expected kyphotic deformity, and uncontrolled infection being managed only with antibiotics. Antibiotics are also important for thorough treatment.

ABSTRACT

Introducción: la discitis es una de las formas de presentación de los procesos infecciosos en el raquis. La de origen hematógeno es más frecuente en los niños y de modo raro aparece en el adulto asociada a una inmunodepresión, porque en esta edad ocurre generalmente como complicación de un proceder quirúrgico sobre el disco intervertebral. Objetivo: establecer las características clínicas e imaginológicas y el tratamiento de esta afección en el adulto. Descripción: se presentó un paciente masculino de 35 años de edad con antecedentes de salud anterior, que comenzó a presentar dolor en columna lumbar e impotencia funcional absoluta. Se realizaron estudios de laboratorio y de imágenes. Los parámetros hematológicos inclinaban al diagnóstico de un proceso infeccioso y la resonancia magnética nuclear evidenció una discitis. El tratamiento consistió en la administración de antibióticos e inmovilización. Conclusiones: el paciente presentó mejoría de los síntomas a las 72 h, con alivio total del dolor a las 2 semanas. Los resultados hematológicos mejoraron paulatinamente hasta alcanzar la normalidad a los 3 meses. Los estudios de imágenes fueron normales a los 6 meses y el paciente se incorporó a sus actividades habituales. la discitis hematógena en el adulto, aunque infrecuente, debe ser sospechada en todo paciente con síntomas dolorosos del raquis de posible origen infeccioso, que no responde a tratamiento médico y mucho más si concomita con algún grado de inmunodepresión(AU)


Introduction: Discitis is one of the forms of presentation of infectious processes of the spine. Discitis of hematogenous origin is more common in children. In adults it is a rare condition associated to immunosuppression, since it generally occurs as a complication of intervertebral disk surgery. Objective: Determine the clinical and imaging characteristics as well as the treatment of this condition in adults. Description: A male 35-year-old patient with a disease history presents with lumbar pain and total functional impotence. Laboratory and imaging studies were conducted. Hematological parameters pointed to an infectious process, and nuclear magnetic resonance imaging revealed a discitis. Treatment consisted of antibiotics and immobilization. Conclusions: The patient showed symptom improvement at 72 hours, with total pain relief at 2 weeks. There was gradual improvement in hematological results, which reached normal levels at 3 months. Imaging studies were normal at 6 months, and the patient resumed his daily routine. Adult hematogenous discitis, though infrequent, should be suspected in any patient with spinal pain symptoms of possible infectious origin not responding to clinical treatment, particularly when it is concomitant with some degree of immunosuppression(AU)


Introduction: la discite est l'une des formes de présentation caractérisant les processus infectieux au niveau du rachis. L'infection hématogène est la plus fréquente chez les enfants, mais rare chez les adultes si associée à une immunodépression, car à l'âge adulte, elle survient généralement comme une complication d'un geste chirurgical sur un disque intervertébral. Objectif: établir les caractéristiques cliniques et par image, et le traitement de cette affection chez l'adulte. Description: un patient du sexe masculin, âgé de 35 ans, avec une histoire médicale connue, ayant une douleur lombaire et un dysfonctionnement absolu, s'est présenté en consultation. Des examens de laboratoire et d'imagerie ont été réalisés. Les résultats hématologiques ont évoqué une infection, et la résonance magnétique nucléaire a mis en évidence une discite. Le traitement a consisté à l'administration des antibiotiques et à l'immobilisation. Conclusion: les symptômes du patient ont résolu à 72 h, la douleur s'est atténuée à 2 semaines. Les résultats hématologiques ont amélioré peu à peu lors de 3 semaines. Les examens d'imagerie sont revenus à la normale à 6 mois, et le patient s'est réincorporé à sa vie quotidienne. La discite hématogène chez l'adulte, quoique rare, doit être soupçonnée chez tout patient ayant une douleur de possible origine infectieuse au niveau du rachis et ne répondant pas au traitement médical, nettement plus si une certaine immunodépression est concomitante(AU)

ABSTRACT

OBJECTIVE: The safety and efficacy of various fusion substitutes in pyogenic osteomyelitis has not been investigated. We evaluated and compared the cadaveric allograft and titanium cages used to reconstruct, maintain alignment and achieve fusion in the management of pyogenic spinal infection. METHODS: There were 33 patients with pyogenic osteomyelitis underwent fusion in this study. Fifteen of the 33 patients were operated on by fusion with allografts (cadaveric patella bones) and 18 of those were operated with titanium mesh cages filled with autologous cancellous iliac bone. After the affected disc and vertebral body resection with pus drainage, cadaveric allograft or titanium cages were inserted into the resected space. Posterior transpedicular screw fixation and rod compression in resected space, where cadaveric allograft or titanium cages were inserted, was performed to prevent the malposition in all patients except in 1 case. Recurrent infection was identified by serial erythrocyte sedimentation rate and cross reactive protein follow-up. Osseous union and recurred infection available at a minimum of 2 years following operation was identified. The amount of kyphosis correction and the subsidence were measured radiographically. RESULTS: Spinal fusion was achieved in 29 of 33 patients. In the cadaveric allograft group, 93.3% of patient (14 of 15) showed the osseous union while 83.3% of patient (15 of 18) in the titanium cage group showed union. Subsidence was noted in 12 of the patients. Twelve patients (36.3%) showed unsettling amounts of subsidence postoperatively whereas 46.6% of patients in the cadaveric allograft group and 37.7% of patients in the titanium cage group showed similar subsidence, respectively. There were statistical difference in the fusion rate (p=0.397) and subsidence rate (p=0.276) between the two groups. There was significant statistical difference in the postoperative improvement of segmental kyphosis between the two groups (p=0.022), that is the improvement in sagittal alignment was greater in the titanium cage group than in the cadaveric allograft group. There was no case of recurred infection. CONCLUSION: The cadaveric allograft and titanium cages are effective and safe in restoring and maintaining sagittal plane alignment without increased incidence in infection recurrence in pyogenic osteomyelitis. The postoperative improvement of segmental kyphosis was better in the cage group.

ABSTRACT

PURPOSE: Pyogenic spinal infection encompasses a broad range of clinical entities, treatment and prognosis. We compared the symptoms and treatment efficacy of patients with single and combined spinal infections. MATERIALS AND METHODS: Between June 2001 and November 2006, 30 patients with pyogenic spinal infections were treated in our hospital and outcomes were evaluated through ESR, CRP, and clinical improvement. Groups 1 and 2 represented patients with single lesions and patients with combined lesions, respectively. RESULTS: Group 1 included 7 men and 8 women, and the preoperative mean ESR and CRP were 62.7 mm/hr and 5.7 mg/dl. The most common clinical presentation was back pain. Nine patients in group 1 underwent operation, and two underwent instrumentation. Group 2 included 4 men and 11 women, and the preoperative mean ESR and CRP were 78.5 mm/hr and 16.7 mg/dl. The most common clinical presentations were back pain and fever. Thirteen patients in group 2 underwent operation, and six underwent instrumentation. There were more underlying diseases in group 2. CONCLUSION: There were more underlying diseases and higher preoperative inflammatory-reactive laboratory findings in patients with combined spinal infections. Careful attention must be directed to treatment in order to secure favorable clinical outcomes in patients with combined infections.

ABSTRACT

OBJECTIVE: The purpose of the study was to determine the clinical effects of anterior radical debridement on a series of patients with spontaneous spinal infection. METHODS: We retrospectively analyzed the clinical characteristics of 32 patients who underwent surgical treatment from January 2000 to December 2005 in our department. The average follow-up Period was 33.4 months (range, 6 to 87 months). Thirty-two patients presented with the following : 23 cases with pyogenic spondylitis, eight with tuberculous spondylitis and one with fungal spondylitis. The indications for surgery were intractable pain, failure of medical management, neurological impairment with or without an associated abscess, vertebral destruction causing spinal instability and/or segmental kyphosis. RESULTS: The study included 15 (46.9%) males and 17 (53.1%) females ranging in age from 26 to 75 years (mean, 53.1 years). Diabetes mellitus (DM) and pulmonary Tbc were the most common predisposing factors for pyogenic spondylitis and tuberculous spondylitis. Staphylococcus aureus (13%) was the main organism isolated. The most prevalent location was the lumbar spine (75%). Changes in the pain score, Frankel's classification, and laboratory parameters demonstrated a significant clinical improvement in all patients. However, there were recurrent infections in two patients with tuberculous spondylitis and inappropriate debridement and intolerance of medication and noncompliance. Autologous rib, iliac bone and allograft (fibular) were performed in most patients. However, 10 patients were grafted using a titanium mesh cage after anterior radical debridement. There were no recurrent infections in the 10 cases using the mesh cage with radical debridement. CONCLUSION: The findings of this study indicate that surgery based on appropriate surgical indications is effective for the control of spinal infection and prevention of recurrence with anterior radical debridement, proper drug use and abscess drainage.

ABSTRACT

OBJECTIVE: This study is performed to evaluate the clinical manifestations and prognostic factors among patients with pyogenic spinal infections. METHODS: The records and radiologic data of 27 patients treated between 2001 and 2003 were retrospectively evaluated. RESULTS: All patients (mean age, 55.2yrs) were treated with i.v. antibiotics and 13(48.1%) required surgical treatment. Mean follow up duration was 38.9 weeks. The sixteen patients(59.2%) had previous surgical procedure on spine and six patients(22.0%) had local injections. The ten patients had predisposing factor (such as, diabetes mellitus, UTI, liver cirrhosis, septic condition). The most common symptoms are lower back pain and motor weakness. Causative organisms determined only in ten patients(37%) and Staphylococcus aureus(50%) was most common. C-reactive protein(CRP) and white blood cell(WBC) count were more correlated with clinical outcome than erythrocyte sedimentation rate(ESR). CONCLUSION: CRP and WBC level can be significant parameters of treatment and prognosis in pyogenic spinal infection.

ABSTRACT

Although the prevalence of infectious disorders has been decreased, tuberculous infections are still common in this country. Therefore epidemiological data for the correct diagnosis of some spinal infections and proper selection of susceptible antibiotics are necessary. We presented a series of 40 patients with primary spinal infection dated from January 1990 to December 1994. Tuberculosis was the most common infection constituting 85% of this series, while pyogenic infection constituted only 10%, and primary discitis shared 5%. In a half of the tuberculous spondylitis, there were histories of previous tuberculosis except the vertebrae. We could identify the pathogenic organisms in only 47.5% o the cases(in 4 of 6 pyogenic infection and 15 of 34 tuberculous infection). Since it is difficult to differentiate the pyogenic and tuberculous infections by clinical or radiological features alone, some pyogenic infections might have been regarded as tuberculous, although the pyogenic spinal infections are rare. Nevertheless the tuberculous spinal infection outnumbered pyogenic ones in this country, which is similar to the patterns of other third-world countries. Therefore, correct identification of the microbial agent is important not only for the proper treatment but also to evaluate the patients of primary spinal infections in this country.
