Conservative versus early surgical treatment in the management of pyogenic spondylodiscitis: a systematic review and meta-analysis. Sci Rep 2023; 13:15647. [PMID: 37730826 PMCID: PMC10511402 DOI: 10.1038/s41598-023-41381-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Accepted: 08/25/2023] [Indexed: 09/22/2023] Open
Abstract
Spondylodiscitis is the commonest spine infection, and pyogenic spondylodiscitis is the most common subtype. Whilst antibiotic therapy is the mainstay of treatment, some advocate that early surgery can improve mortality, relapse rates, and length of stay. Given that the condition carries a high mortality rate of up to 20%, the most effective treatment must be identified. We aimed to compare the mortality, relapse rate, and length of hospital stay of conservative versus early surgical treatment of pyogenic spondylodiscitis. All major databases were searched for original studies, which were evaluated using a qualitative synthesis, meta-analyses, influence, and regression analyses. The meta-analysis, with an overall pooled sample size of 10,954 patients from 21 studies, found that the pooled mortality among the early surgery patient subgroup was 8% versus 13% for patients treated conservatively. The mean proportion of relapse/failure among the early surgery subgroup was 15% versus 21% for the conservative treatment subgroup. Further, it concluded that early surgical treatment, when compared to conservative management, is associated with a 40% and 39% risk reduction in relapse/failure rate and mortality rate, respectively, and a 7.75 days per patient reduction in length of hospital stay (p < 0.01). The meta-analysis demonstrated that early surgical intervention consistently significantly outperforms conservative management in relapse/failure and mortality rates, and length of stay, in patients with pyogenic spondylodiscitis.

Abstract
Objective To analyze the effect of percutaneous endoscopic lumbar discectomy in treating lumbar intervertebral infections. Methods A total of 13 patients with lumbar intervertebral infections who underwent percutaneous endoscopic lumbar discectomy combined with external drainage between November 2016 and December 2019 were enrolled in the present study. After the operation, sensitive antibiotics were used based on the results of the bacterial culture. If no pathogens were detected in the biopsy culture of the infected tissues, empirical antibiotics were administrated to these patients. The clinical efficacy was evaluated by using a visual analog scale (VAS), Japanese Orthopaedic Association (JOA), Oswestry Disability Index (ODI), and standard Macnab's evaluation. Postoperative computed tomography (CT) and MRI were also used to evaluate clinical efficacy. Results The follow-up time was 10–18 months, and the average time was (13.69 ± 2.63) months. Causative bacteria were isolated in 7 of 13 infected tissue biopsy cultures. Systemic antibiotics and anti-tuberculous chemotherapy were administered according to sensitivity studies for identified. There were no pathogens isolated from the other six patients. Empiric antibiotics were administrated in these patients. One week after the operation, WBC, a fractional fraction of medium granulocytes, ESR and CRP were significantly lower compared to before the operation (all P < 0.05). At the last follow-up visit, the above-mentioned markers were all within normal range, which differed compared to the pre-operative data (P < 0.05). The VAS and ODI of the patients at 1 week and 3 months after operation were significantly lower compared to preoperative data (all P < 0.05). During the last follow-up visit, seven patients were excellent, five were good, and one was poor according to standard Macnab's evaluation. No serious complications were recorded. Conclusions Percutaneous lumbar discectomy combined with external drainage resulted as an effective method for treating lumbar intervertebral infections and was associated with fewer injuries, less pain, low cost, and low recurrence rate.

Risk factors for surgical intervention in patients with primary spinal infection on initial presentation. J Neurosurg Spine 2022; 37:283-291. [PMID: 35120318 DOI: 10.3171/2021.12.spine21811] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2021] [Accepted: 12/09/2021] [Indexed: 11/06/2022]
Abstract
OBJECTIVE Treatment of primary spinal infection includes medical management with or without surgical intervention. The objective of this study was to identify risk factors for the eventual need for surgery in patients with primary spinal infection on initial presentation. METHODS From January 2010 to July 2019, 275 patients presented with primary spinal infection. Demographic, infectious, imaging, laboratory, treatment, and outcome data were retrospectively reviewed and collected. Thirty-three patients were excluded due to insufficient follow-up (≤ 90 days) or death prior to surgery. RESULTS The mean age of the 242 patients was 58.8 ± 13.6 years. The majority of the patients were male (n = 130, 53.7%), White (n = 150, 62.0%), and never smokers (n = 132, 54.5%). Fifty-four patients (22.3%) were intravenous drug users. One hundred fifty-four patients (63.6%) ultimately required surgery while 88 (36.4%) never needed surgery during the duration of follow-up. There was no significant difference in age, gender, race, BMI, or comorbidities between the surgery and no-surgery groups. On univariate analysis, the presence of an epidural abscess (55.7% in the no-surgery group vs 82.5% in the surgery group, p < 0.0001), the median spinal levels involved (2 [interquartile range (IQR) 2-3] in the no-surgery group vs 3 [IQR 2-5] in the surgery group, p < 0.0001), and active bacteremia (20.5% in the no-surgery vs 35.1% in the surgery group, p = 0.02) were significantly different. The cultured organism and initial laboratory values (erythrocyte sedimentation rate, C-reactive protein, white blood cell count, creatinine, and albumin) were not significantly different between the groups. On multivariable analysis, the final model included epidural abscess, cervical or thoracic spine involvement, and number of involved levels. After adjusting for other variables, epidural abscess (odds ratio [OR] 3.04, 95% confidence interval [CI] 1.64-5.63), cervical or thoracic spine involvement (OR 2.03, 95% CI 1.15-3.61), and increasing number of involved levels (OR 1.16, 95% CI 1.01-1.35) were associated with greater odds of surgery. Fifty-two surgical patients (33.8%) underwent decompression alone while 102 (66.2%) underwent decompression with fusion. Of those who underwent decompression alone, 2 (3.8%) of 52 required subsequent fusion due to kyphosis. No patient required hardware removal due to persistent infection. CONCLUSIONS At time of initial presentation of primary spinal infection, the presence of epidural abscess, cervical or thoracic spine involvement, as well as an increasing number of involved spinal levels were potential risk factors for the eventual need for surgery in this study. Additional studies are needed to assess for risk factors for surgery and antibiotic treatment failure.

Abstract
Mucormycosis is an extremely rare, invasive infection commonly isolated to patients with known immunosuppressed status. In the present case, a 36-year-old woman, with a history of T-cell acute lymphoblastic leukemia in remission, presented with T4 osteomyelitis and an associated epidural collection. Biopsy was consistent with mucormycosis, and the patient was recommended for surgical debridement. After declining debridement, the patient was successfully managed on a multiagent antifungal regimen consisting of intravenous amphotericin B, micafungin, and oral posaconazole. The patient was alive without clear evidence of disease at eight months, representing one of the first cases of spinal mucormycosis infection successfully treated with medical management alone. We additionally review the previous descriptions of spinal mucormycosis infections to identify those interventions most associated with successful clearance or containment of these infections.

Abstract
Objective In the present study, we aimed to describe the clinical features, diagnosis, treatment, and prognosis of spinal epidural abscess (SEA). Methods The complete clinical data of 11 SEA patients who were treated in our hospital system from January 2015 to June 2018 were retrospectively analyzed. Moreover, the clinical features, diagnosis, treatment, and prognosis of 642 SEA cases collected from the foreign literature from 2010 to 2019 were also investigated. Results Among our 11 SEA patients, nine cases had purulent inflammation, two cases had tuberculosis, two cases had infection caused by Staphylococcus aureus, one case had infection caused by Streptococcus constellatus, one case had infection caused by Klebsiella pneumoniae, five cases showed negative bacterial culture, and two cases had Mycobacterium tuberculosis. All 11 cases showed focal spinal pain, eight cases exhibited neurological deficits, and six cases experienced fever. Nine of the 11 cases involved the lumbosacral spine, one case involved the thoracic spine, and one case involved the cervical spine. Eight patients had a longer course of disease (>2 weeks), all 11 patients had vertebral osteomyelitis, and nine patients had intervertebral discitis. One patient had motor dysfunction of arms and legs, one patient had lower limb motor dysfunction, one patient had limb numbness, one patient experienced relapse after the conservative treatment, and one patient experienced relapse after the surgical treatment. The follow-up time was 15–24 months. Conclusion The classic diagnosis of triads (focal spine pain, neurological deficit, and fever) was less specific for SEA. MRI examination, blood culture, tissue culture, and biopsy could be used for the diagnosis for SEA. Suppuritis was a common cause of SEA. Early detection, early diagnosis and early treatment, as well as the selection of the most suitable treatment regimen based on comprehensive evaluation, played crucial roles in a better prognosis of SEA. There was no statistically significant difference in terms of the general condition, diagnosis, treatment and prognosis between the patients with negative and positive culture results (P>0.05). For SEA patient with negative culture, antibiotic treatment should be used empirically.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVE To develop a comprehensive understanding of the prognostic value of laboratory markers on morbidity and mortality following epidural abscess. SUMMARY OF BACKGROUND DATA Spinal epidural abscess is a serious medical condition with high rates of morbidity. The value of laboratory data in forecasting morbidity and mortality after epidural abscess remains underexplored. METHODS We obtained clinical data on patients treated for epidural abscess at two academic centers from 2005 to 2017. Our primary outcome was the development of one or more complications within 90-days of presentation, with mortality a secondary measure. Primary predictors included serum albumin, serum creatinine, platelet-lymphocyte ratio, and ambulatory status at presentation. We used multivariable logistic regression techniques to adjust for confounders. The most parsimonious set of variables influencing both complications and mortality were considered to be clinically significant. These were then examined individually and in combination to assess for synergy along with model-discrimination and calibration. We performed internal validation with a bootstrap procedure using sampling with replacement. RESULTS We included 449 patients in this analysis. Complications were encountered in 164 cases (37%). Mortality within 1-year occurred in 39 patients (9%). Regression testing determined that serum albumin, serum creatinine, and ambulatory status at presentation were clinically important predictors of outcome, with albumin more than 3.5 g/dL, creatinine less than or equal to 1.2 mg/dL, and independent ambulatory function at presentation considered favorable characteristics. Patients with no favorable findings had increased likelihood of 90-day complications (odds ratio [OR] 5.43; 95% confidence intervals [CI] 1.98, 14.93) and 1-year mortality (OR 8.94; 95% CI 2.03, 39.37). Those with one favorable characteristic had greater odds of complications (OR 4.00; 95% CI 2.05, 7.81) and mortality (OR 5.71; 95% CI 1.60, 20.43). CONCLUSION We developed a nomogram incorporating clinical and laboratory values to prognosticate outcomes after treatment for epidural abscess. The results can be used in shared-decision making and counseling. LEVEL OF EVIDENCE 3.
