[Pyogenic spondylitis after Corynebacterium striatum blood stream infection following allogeneic hematopoietic stem cell transplantation for malignant lymphoma].

Patient 1 was a 70-year-old woman with refractory diffuse large B-cell lymphoma who received allogeneic peripheral blood stem cell transplantation from an HLA-haploidentical related donor. Upper back pain appeared on day63, and Th8-Th9 pyogenic spondylitis was diagnosed based on magnetic resonance imaging (MRI). Blood culture on day14 identified Corynebacterium striatum as the causative bacteria of blood stream infection (BSI). The pyogenic spondylitis resolved after treatment with daptomycin for 2 months. Patient 2 was a 65-year-old man with relapsed angioimmunoblastic T-cell lymphoma who received bone marrow transplantation from an HLA-DR single-antigen-mismatched unrelated donor. Lower back pain appeared on day30, and L4-L5 pyogenic spondylitis was diagnosed based on MRI. Blood culture was negative. Daptomycin and clindamycin were selected for treatment based on the drug susceptibility of bacteria that had caused pre-engraftment BSI (Escherichia coli on day3 and Corynebacterium striatum on day9), and the pyogenic spondylitis resolved after 6 months of this treatment. Pyogenic spondylitis should be considered in the differential diagnosis of back pain accompanied by BSI before engraftment in allogeneic hematopoietic stem cell transplant recipients.

Bacterial and Viral Infectious Disease of the Spine.

Spinal infections are a diverse group of diseases affecting different compartments of the spine with variable clinical and imaging presentations. Diagnosis of spinal infections is based on a combination of clinical features, laboratory markers, and imaging studies. Imaging plays a pivotal role in the diagnosis and management of spinal infections. The characteristic imaging manifestations of bacterial and viral infections in the spine are discussed with key teaching points emphasized.

Application of Metagenomic Next-Generation Sequencing in Suspected Spinal Infectious Diseases.

OBJECTIVE: This study aimed to explore the clinical efficacy of metagenomic next-generation sequencing (mNGS) in diagnosing and treating suspected spinal infectious diseases. METHODS: Between October 2022 to December 2023, a retrospective analysis was performed on patient records within the Department of Spinal Surgery at Guilin People's Hospital. The analysis included comprehensive data on patients with presumed spinal infectious diseases, incorporating results from mNGS tests conducted externally, conventional pathogen detection results, laboratory examination results, and imaging findings. The study aimed to assess the applicability of mNGS in the context of suspected spinal infectious lesions. RESULTS: Twenty-seven patients were included in the final analysis. Pathogenic microorganisms were identified in 23 cases. The included cases encompassed 1 case of tuberculous spondylitis, 1 case of fungal infection, 3 cases of Brucella spondylitis, 3 cases of viral infection, 9 cases of bacterial infection, and 6 cases of mixed infections. Pathogenic microorganisms remained elusive in 4 cases. The application of the mNGS method demonstrated a significantly elevated positive detection rate compared to conventional methods (85.19% vs. 48.15%, P < 0.05). Moreover, the mNGS method detected a greater variety of pathogen species than traditional methods (Z = 10.69, P < 0.05). Additionally, the mNGS method exhibited a shorter detection time. CONCLUSIONS: mNGS demonstrated significantly higher detection rates for bacterial, fungal, viral, and mixed infections in cases of suspected spinal infectious diseases. The clinical implementation of mNGS could further enhance the efficiency of diagnosing and treating suspected spinal infectious diseases.

Relationship between TLR-2 level and clinical or radiological severity on patients with tuberculosis spondylitis in Dr. Wahidin Sudirohusodo hospital Makassar.

Spinal tuberculosis or TB spondylitis is one of the most common types of extra pulmonary tuberculosis, which is about 15% of all cases. It causes severe morbidity, neurological deficits, and severe deformities in the patients. The growth of Mycobacterium tuberculosis in culture specimens obtained from infected tissue is the single gold standard diagnostic test for spinal TB. Toll-like receptor (TLR) is one of the important receptors in the first-line defence system against microbes. TLR-2 and TLR-4 are known to be associated with tuberculosis infection. Based on this background, the researchers were interested in examining the relationship between TLR-2 levels and the clinical and radiological severity of TB spondylitis patients. A cross-sectional study was conducted with patients diagnosed with tuberculosis spondylitis at Dr Wahidin Sudirohusodo Makassar. Patients diagnosed with TB spondylitis confirmed by blood tests, GeneExpert, and magnetic resonance imaging without prior treatment were included. Data analysis were conducted by using descriptive analysis and one-way ANOVA for bivariate analysis. The mean value of TLR2 levels in TB spondylitis patients was 9.1 g/dL. TLR2 levels in paraesthesia were significantly higher than normal (P < .05). Similar trend were analyzed on the motor neurologic status with TLR2 levels in paraparesis were significantly higher than those in normal (P < .05). There is a significant relationship between the TLR2 levels in TB spondylitis and their impaired motor and sensory function. Spinal destruction has been shown to provide significant relationship with TLR2 value in spondylitis TB.

Clinical profile, diagnosis, treatment, and outcome of patients with tubercular versus nontubercular causes of spine involvement: A retrospective cohort study from India.

Background: In tuberculosis (TB) endemic areas, other pyogenic causes of spine involvement may be missed. The study aimed to describe TB and non-TB causes of spine involvement and identify features that can help in differentiating them. Methods: A retrospective cohort study was conducted to screen the clinical records of all admitted patients (Kasturba Hospital, Manipal) in 2018-20 for a diagnosis of spondylitis and/or sacroiliitis. The clinical features, radiological findings, laboratory parameters, treatment details, and outcomes were compared among those diagnosed with confirmed TB, confirmed brucellosis, or confirmed pyogenic infection. A scoring system was also developed to differentiate spondylodiscitis due to tuberculous and pyogenic causes. The qualitative variables were compared using the Chi-square test, while quantitative variables were compared using the one-way analysis of variance test. Results: Of 120 patients with spine infections, a total of 85 patients were confirmed with the microbiological diagnosis of interest. Involvement of the thoracic spine, longer duration of illness, and caseous granulomatous reaction on histopathology was more common in TB patients. Male gender, involvement of lumbar vertebra, and neutrophilic infiltrate on histopathology were more common in brucellosis patients. Male gender, diabetes mellitus, involvement of lumbar vertebra, neutrophilic infiltrate on histopathology, leukocytosis, and increased C-reactive protein were more commonly seen in patients with pyogenic infection. The scoring system had a sensitivity and specificity of 75% and 91%, respectively, when used to differentiate TB from pyogenic infection. Conclusions: In resource-limited settings, suggestive findings can be used to decide empiric therapy.

Tuberculous spondylitis following intravesical Bacillus Calmette-Guérin therapy for bladder cancer surgically treated through the anterior approach.

Intravesical BCG therapy is commonly used to treat superficial bladder cancer. Although various complications associated with this therapy have been reported, tuberculous spondylitis is uncommon. Here, we report a rare case of tuberculous spondylitis that occurred after intravesical BCG therapy for bladder cancer. A man in his 80s received BCG immunotherapy for bladder cancer and developed low back pain after treatment. Remarkably, he presented with neurological symptoms. Spondylitis was suspected on imaging. CT-guided biopsy was performed to confirm the diagnosis. Consequently, Mycobacterium bovis was identified as the causative pathogen by multiplex PCR. Multidrug therapy, administered for several months, was ineffective. Therefore, surgery was performed through an anterior approach. The symptoms, including low back pain, improved and postoperative C reactive protein tests were within the normal range. Tuberculous spondylitis following BCG therapy should be considered in cases with a history of bladder cancer treatment.

A rare case of thoracic brucellosis misdiagnosed as malignant tumor and literature review.

Brucellosis remains a major public health problem worldwide. It is commonly found in most developed and developing countries, such as the Mediterranean region, the Middle East, and Latin America. In China, brucellosis is mainly distributed in some of the northern provinces and is relatively rare in Shandong province. Brucellosis has a variety of clinical manifestations, with fever, sweating, fatigue, and migratory joint pain being the most common. Because of the non-specific clinical symptoms, brucellosis is often misdiagnosed as other diseases. Here, we report a rare case of brucellosis of thoracic vertebrae misdiagnosed as thoracic malignant tumor and present a review of related literature.

Differentiating brucella spondylitis from tuberculous spondylitis by the conventional MRI and MR T2 mapping: a prospective study.

BACKGROUND: Brucella spondylitis (BS) and tuberculous spondylitis (TS), caused initially by bacteremia, are the two leading types of granulomatous spinal infections. BS is easy to miss or may be misdiagnosed as TS. Our purpose aims to differentiate BS from TS in conventional MR imaging and MR T2 mapping. METHODS: We performed on 26 BS and 27 TS patients conventional MR imaging and MR T2 mapping. We analyzed the features in conventional MR imaging and measured T2 values of the lesion vertebrae (LV) and unaffected adjacent vertebrae (UAV) in BS and TS patients, respectively. RESULTS: There were no significant differences in sex, age, national between BS and TS. There was significantly lower severity of vertebral destruction, vertebral posterior convex deformity, dead bone, and abscess scope in BS when compared to TS (p < 0.001, p = 0.048, p < 0.001, p < 0.001, respectively). The vertebral hyperplasia was significantly higher in BS when compared to TS (p < 0.001). The T2 value of the LV with BS was markedly higher than that in the UAV with BS and that in the LV and UAV with TS (p < 0.001, p < 0.037, p < 0.001, respectively). The T2 value of the LV with TS was significantly higher than that of the UAV in TS and BS (p < 0.001, p < 0.001, respectively). There were no significant differences in the T2 value of the UAV between BS and TS (p = 0.568). CONCLUSIONS: The qualitative and quantitative evaluation may differentiate BS from TS. The conventional MR imaging helps to distinguish BS from TS by several distinctive features. MR T2 mapping has the additional potential to provide quantitative information between BS and TS.

Klebsiella sp.-related infectious spondylitis in a bearded dragon (Pogona vitticeps).

BACKGROUND: Spondylitis is an inflammation of the vertebrae that leads to a destructive process with exuberant new bone formation. Osteomyelitis can produce a distortion of the bone architecture, degenerative joint changes and ankyloses of adjacent vertebrae. In reptiles, intervertebral discs are absent, so the term discospondylitis is not used. In lizards, vertebral lesions have not been well studied. The present paper describes the first case of Klebsiella sp.-related spondylitis in a pet lizard (Pogona vitticeps). CASE PRESENTATION: A 2-year-old, female bearded dragon (Pogona vitticeps) was presented for clinical examination due to a decreased activity level, decreased appetite and constipation. Blood tests showed no remarkable alterations. The haemogram showed normal parameters with relative lymphocytosis, although the absolute number of lymphocytes did not differ from the reference values. A computed tomography scan revealed a mixed osteolytic-proliferative bone lesion diffusing to the first and last tracts of the pre-sacral vertebrae together. A small amount of material obtained from the spinal swelling was sampled with an aseptic technique for bacterial culture, which was positive for Klebsiella sp. The antibiogram revealed sensitivity to enrofloxacin, marbofloxacin, and chloramphenicol and intermediate sensitivity to gentamicin. Complete return to spontaneous feeding was achieved 15 days after the beginning of antibiotic and anti-inflammatory therapy. CONCLUSIONS: In veterinary medicine, spondylitis represents a well-known disease in small companion animals. In mammals, the most common aetiologic agents are fungi and bacteria. Antibiotic therapy was set based on the antibiogram, and marbofloxacin was chosen at a dosage of 10 mg/kg subcutaneously (SC) once per day (SID). After only 7 days of antibiotic therapy, the clinical condition improved significantly; the patient started feeding and drinking spontaneously and gained weight. This case should remind clinicians of the importance of always performing antibiograms before choosing any antibiotic therapy. Considering reptiles, there have been few papers about spinal diseases, mostly regarding snakes and a few about Iguana iguana. Relative to other species of saurians, the literature remains lacking.

The Association of Spondylitis and Aortic Aneurysm Disease.

OBJECTIVES: The aim of this study is to assess any relation between spondylitis and aortic aneurysmal disease by reviewing the current literature. METHODS: A systematic search was undertaken using MEDLINE, EMBASE and CENTRAL databases till May 2019, for articles reporting on patients suffering from spondylitis and aortic aneurysm. RESULTS: The most involved aortic segment was infrarenal aorta (56.9%). The lumbar vertebrae were more frequently affected (79.7%). Commonest symptoms were back pain (79.1%), fever (33.7%) and lower limb pain (29.1%). 55.8% of cases were diagnosed using computed tomography. The pathology was attributed to infectious causes in 25.1% of cases. 53.4% of patients were treated only for the aneurysm, 27.9% for both pathologies, while two patients solely for the vertebral disease. Endovascular aneurysm repair was chosen in 12.8% of cases. The 30-day mortality was 8.1% (7/86); mostly from vascular complications. CONCLUSIONS: A synchronous spondylitis and aortic aneurysm may share common etiopathology, when an infectious or inflammatory cause is presented. The lumbar vertebrae are more frequently affected. Low quality data do not allow safe conclusion to suggest the best treatment option.

Surgical management for lumbar brucella spondylitis: Posterior versus anterior approaches.

ABSTRACT: There has been no ideal surgical approach for lumbar brucella spondylitis (LBS). This study aims to compare clinical efficacy and safety of posterior versus anterior approaches for the treatment of LBS.From April 2005 to January 2015, a total of 27 adult patients with lumbar brucella spondylitis were recruited in this study. The patients were divided into 2 groups according to surgical approaches. Thirteen cases in group A underwent 1-stage anterior debridement, fusion, and fixation, and 14 cases in group B underwent posterior debridement, bone graft, and fixation. The clinical and surgical outcomes were compared in terms of operative time, intraoperative blood loss, hospitalizations, bony fusion time, complications, visual analog scale score, recovery of neurological function, deformity correction.Lumbar brucella spondylitis was cured, and the grafted bones were fused within 11 months in all cases. It was obviously that the operative time and intraoperative blood loss of group A were more than those of group B (P = .045, P = .009, respectively). Kyphotic deformity was signifcantly corrected in both groups after surgery; however, the correction rate was higher in group B than in group A (P = .043). There were no significant differences between the two groups in hospitalizations, bony fusion time, and visual analog scale score in the last follow-up (P = .055, P = .364, P = .125, respectively).Our results suggested that both anterior and posterior approaches can effectively cure lumbar brucella spondylitis. Nevertheless, posterior approach gives better kyphotic deformity correction, less surgical invasiveness, and less complications.

A case report of endocarditis and spondylitis caused by Brucella melitensis biovar 3.

BACKGROUND: This case report describes the clinical process of a shepherd who suffered brucellosis-related endocarditis (BE) and spondylitis (BS) and was infected with Brucella melitensis biovar 3 (B. melitensis biovar 3). CASE PRESENTATION: A 55-year-old male patient was admitted to The First Affiliated Hospital of Shihezi University on October 11, 2018, due to over 3 months of intermittent fever, back pain, and heart trouble. The Rose Bengal Plate test was positive, the standard agglutination test titer for brucellosis was 1/800, and the blood culture was positive for B. melitensis biovar 3. Three instances of transthoracic echocardiography examination at days 1, 25, and 376 after admission to the hospital and magnetic resonance imaging (MRI) and computed tomography (CT) checks at days 5 and 38 revealed that the size of the vegetation on the posterior leaflet of the mitral valve increased from 0.7 × 1.4 cm to 1.2 × 1.5 cm and that the left atrium and ventricle were enlarged. The MRI and CT results showed hyperplasia of the second and third vertebra, a cold abscess formed on both sides of the psoas major muscles, and the vertebra hyperplasia became aggravated at a later time point. The patient's situation deteriorated, and heart failure was discovered on October 22, 2019. At the moment of submission of this manuscript, the patient remains in bed at home because of severe debility caused by brucellosis. CONCLUSIONS: This is the first reported case of endocarditis combined with spondylitis caused by B. melitensis biovar 3 in a shepherd. Brucellosis infection can cause work-power losses because of misdiagnosis or a lack of proper treatment. Early diagnosis and treatment are essential for a successful outcome.

Tuberculosis spondylitis in patients on hemodialysis: Clinical features, risk factors, and outcomes in 12 patients.

The aim of this study was to investigate the clinical features, risk factors and outcomes of tuberculosis spondylitis (TBS) in patients on hemodialysis (HD). We systematically reviewed medical records from 12 HD patients with TBS admitted to our hospital from April 2008 to April 2018. A total of 120 age- and sex-matched HD patients without infections were randomly selected as controls. The incidence of TBS in our patient group was 1.5/1000 per year. The average duration from initial symptoms to diagnosis was 45.4 days (range, 11-180 days). Neurosurgery was performed in 4 (33.3%) patients. TBS was cured or improved in 11 (91.7%) patients. HD patients with TBS had significantly lower albumin and Hb levels than controls (P = .03 and P = .01). These findings indicated that lower albumin and Hb levels were possible risk factors for TBS in patients on HD, most HD patients with TBS had a good outcome after anti-TB therapy with or without surgery.

Pyogenic Spondylitis with Rapid Bone Destruction After Chemoradiotherapy for Tongue Cancer: A Case Report and Literature Review.

Radiation therapy is a frequently used effective treatment for head and neck cancer. It has several adverse effects of which osteomyelitis is a late complication of radiotherapy. Although uncommon, when it occurs in the vertebral body, it results in pyogenic spondylitis, which can be fatal. We report a case of pyogenic spondylitis, observed 2 years and 5 months after chemoradiotherapy following surgery for the treatment of tongue cancer. The initial symptoms were fever and posterior cervical pain. Initial CT images showed no abnormality in the cervical spine. However, when CT and MRI were followed over time, bone destruction and abscess formation were observed at the C3 and C4 vertebral endplates. Hence, CT-guided puncture d rainage was performed from the anterior neck. The collected pus was d iagnosed as Class II pyogenic spondylitis by cytology and the culture test revealed the presence of Streptococcus agalactiae. The infection was successfully treated by drainage and antibacterial chemotherapy.

Bacillus Calmette-GuÉrin-Associated Cervical Spondylitis in a 3-Year-Old Immunocompetent Girl.

Bacillus Calmette-Guérin (BCG)-associated osteomyelitis is a rare adverse event following BCG vaccination, and there have been no previous reports of BCG-associated cervical spondylitis. Here, we describe the case of a 3-year-old immunocompetent girl who developed BCG-associated cervical spondylitis and was successfully treated by prompt surgical drainage of the abscess and administration of isoniazid and rifampicin for 9 months without sequelae.

Cervical spinal tuberculosis combined with brucellosis.

INTRODUCTION: In some developing countries, tuberculosis and brucellosis, which are commom causes of spinal infections, are still common infectious diseases. However, co-occurrence of spinal tuberculosis and brucellosis is rare. METHODOLOGY: We report a case a 47-year-old male engaged in aquaculture with a medical history of numbness, weakness, fever, and night sweats in both upper limbs for about 10 days. Serum agglutination test (SAT) for Brucella revealed brucella infection. Cervical computed tomography (CT) scan and magnetic resonance imaging (MRI) suggested C6, C7 vertebral destruction and corresponding segmental nerve compression. Based on preoperative clinical symptoms and auxiliary examination, brucellar spondylitis was first suspected. According to the postoperative pathological examination, the patient was finally diagnosed as cervical spinal tuberculosis combined with brucellosis. RESULTS: The preoperative symptoms of the patient decreased significantly after surgery, and the patient recovered and leaved hospital within two weeks of starting treatment. At the 6-month follow-up, the patient's clinical symptoms completely disappeared, and all laboratory tests returned to normal. CONCLUSION: Cervical spinal tuberculosis combined with brucellosis is a relatively rare condition. In areas with high rates of tuberculosis and brucellosis, we should conduct comprehensive examinations to avoid misdiagnosis and missed diagnosis.

Safety and efficacy of polyetheretherketone (PEEK) cages in combination with one-stage posterior debridement and instrumentation in Lumbar Brucella Spondylitis.

OBJECTIVE: The aim of this study was to explore the efficacy and safety of surgical treatment of lumbar brucella spondylitis with PEEK cages combined with one-stage posterior debridement and instrumentation. METHODS: We performed a retrospective study for adult patients with lumbar brucella spondylitis. Medical records, imaging studies and laboratory data were collected, back pain was measured by employing the visual analog scale (VAS) and the neurological status was evaluated by using the American Spinal Injury Association (ASIA) scale. RESULTS: A total of 61 consecutive patients (42 males and 19 females) were enrolled with the mean age at presentation of 56.33 ±â€¯9.16 years old. L3-4 and L4-5 were the most infected levels with the ratios of 21.31 % and 19.67 % respectively. Moreover, 12 (19.67 %) patients suffered multiple-level infection and 5 (5/12, 41.67 %) of them had non-contiguous spondylitis. In addition, epidural masses were found in 26 (42.62 %) cases and psoas abscesses were found in 14 (22.95 %) cases. The number of operative segment depended on operation indications (failure of conservative measures, instability, kyphosis, intractable pain and/or neurological impairment). VAS scores were significantly improved at 6-weeks and the last follow-up. Among the 23 (37.70 %) patients with neurological deficits, 19 (19/23, 82.61 %) obtained a full recovery and 4 (4/23, 17.39 %) had been improved incompletely during the last follow-up. All patients exhibited satisfactory bone fusion during the last follow-up. Local infection of surgical site was identified in 6 (9.84 %) cases and no other surgery-related complications were found. CONCLUSION: Use of PEEK cages for interbody fusion is feasible and safe in patients suffering from lumbar brucella spondylitis.

Case report: Candida krusei spondylitis in an immunocompromised patient.

BACKGROUND: Invasive infections with Candida krusei are uncommon and rarely complicated by spondylitis. Previous described cases were solely treated with antimycotic therapy, despite guidelines recommending surgical interventions. CASE PRESENTATION: We describe a case of C. krusei spondylitis in a patient treated with chemotherapy for acute myeloid leukemia. After induction chemotherapy, the patient developed a candidemia, which was treated with micafungin. One month after the candidemia, the patient was admitted with severe lumbar pain. Spondylitis of the L4 and L5 vertebra was diagnosed on MR-imaging, with signs suggesting an atypical infection. The patient was treated with anidulafungin combined with voriconazole. Despite maximal conservative management symptoms gradually worsened eventually requiring surgical intervention. CONCLUSIONS: In contrast to previous case reports, antimycotic treatment alone could be insufficient in treating C. krusei spondylitis.
