Management Of Acute Hematogenous Osteomyelitis Research Articles

Ten-year Review of Acute Pediatric Hematogenous Osteomyelitis at a New Zealand Tertiary Referral Center.

Acute hematogenous osteomyelitis (AHO) remains a cause of severe illness among children with the possibility of long-term consequences for growth and development. Recent research has highlighted an unusually high burden of disease in the New Zealand population compared with other Western regions. We have sought to identify trends in presentation, diagnosis, and management of AHO, with added focus on ethnicity and access to health care. A 10-year retrospective review of all patients <16 years with presumed AHO presenting to a tertiary referral center between 2008 and 2018 was performed. One hundred fifty-one cases met inclusion criteria. The median age was 8 years with a male predominance (69.5%). Staphylococcus aureus was the most common pathogen using traditional laboratory culture method (84%). The number of cases per year decreased from 2008 to 2018. Assessment using New Zealand deprivation scores showed Māori children were most likely to experience socioeconomic hardship ( P ≤0.01). Median distance traveled by families to first hospital consult was 26km (range 1 to 178km). Delayed presentation was associated with need for prolonged antibiotic therapy. Incidence of disease varied by ethnicity with 1:9000 cases per year for New Zealand European, 1:6500 for Pacific, and 1:4000 for Māori. Overall recurrence rate was 11%. The incidence of AHO in New Zealand is concerningly high within Māori and Pacific populations. Future health interventions should consider environmental, socioeconomic, and microbiological trends in the burden of disease. Retrospective study, Level III.

Diagnosis, treatment approaches and modalities of acute hematogenous osteomyelitis in children: a literature review

Acute hematogenous osteomyelitis (AHO) in children is a serious condition that affects the bones and is caused by different organisms. Reliable history, physical examination, basic laboratory tests, and radiological imaging studies lead to early detection and a significant reduction in morbidity and mortality. In contrast, long-term complications and morbidity are mainly due to delays in diagnosis and inadequate management. This literature review aimed to provide an evidence-based, comprehensive summary of AHO in children regarding the definition, epidemiology, risk factors, causes, pathogenesis, clinical picture, and differential diagnosis, specifically focusing on diagnosis and management. Most updated knowledge from the current literature reviews, systematic reviews, and practical guidelines have been summarized by targeting literature search on PubMed and Google Scholar, including articles published until November 2021. Despite the morbidity and frequency of AHO in children, it was found that there are low numbers of high-quality, updated data in this regard, especially the diagnosis and management of AHO in children. For this reason, the authors have provided an updated comprehensive summary of AHO in children to contribute to filling the research gap on this important topic.

1333. Prognostic Factors Associated with Complications of Acute Hematogenous Osteomyelitis in Children

Abstract Background The clinical presentation and management of acute hematogenous osteomyelitis (AHO) in children can vary significantly. Scores to predict acute complications utilize prolonged fever after antibiotics, bone abscess, suppurative arthritis, disseminated infection and delayed source control. By contrast, elevated CRP after 48-96 hours of therapy, disseminated disease and bone debridement are predictive of chronic complications. Such scoring systems have undergone limited validation. We examined factors associated with acute and chronic AHO complications at our center to identify other variables that may enhance published scores. Methods A retrospective chart review was conducted of all children 6 mo-18 years with AHO and with acute symptoms of &amp;lt; 14 days at Texas Children’s Hospital from January 2012 through December 2020. An acute complicated course was defined as treatment failure within 6 weeks of starting antibiotics, &amp;gt; 2 bone debridements, prolonged admission ( &amp;gt;14 days) and acute avascular necrosis. Chronic complications included growth arrest or limb leg discrepancy, pathologic fracture, avascular necrosis, chronic osteomyelitis or frozen joint. Statistical analysis was completed using STATA 17. Results 418 patients met the inclusion criteria. 106 (25.4%) had an acute complicated course. 51 (13.5%) of 377 followed had a chronic complication. Clinical factors associated with acute and chronic complications were very similar. Factors associated with either an acute complicated course (Figure 1) or chronic orthopedic complications (Figure 2) included: older age, tibia involvement, infection due to S. aureus/MRSA, presence of multifocal or disseminated infection, DVT, fever &amp;gt; 48 hours of antibiotic therapy, admission laboratory values including higher absolute neutrophil count (ANC) and higher CRP, ICU admission, associated suppurative arthritis, bacteremia, bone abscess, surgical debridement and delayed source control. Conclusion In children with AHO, risk factors for acute and chronic complications are highly similar. Older age, tibia involvement, MRSA, higher ANC and bacteremia were linked to complications in our population and will be assessed in current clinical scoring systems which may help guide management.

Clinical Practice Guideline by the Pediatric Infectious Diseases Society and the Infectious Diseases Society of America: 2021 Guideline on Diagnosis and Management of Acute Hematogenous Osteomyelitis in Pediatrics.

This clinical practice guideline for the diagnosis and treatment of acute hematogenous osteomyelitis (AHO) in children was developed by a multidisciplinary panel representing Pediatric Infectious Diseases Society (PIDS) and the Infectious Diseases Society of America (IDSA). This guideline is intended for use by healthcare professionals who care for children with AHO, including specialists in pediatric infectious diseases, orthopedics, emergency care physicians, hospitalists, and any clinicians and healthcare providers caring for these patients. The panel's recommendations for the diagnosis and treatment of AHO are based upon evidence derived from topic-specific systematic literature reviews. Summarized below are the recommendations for the diagnosis and treatment of AHO in children. The panel followed a systematic process used in the development of other IDSA and PIDS clinical practice guidelines, which included a standardized methodology for rating the certainty of the evidence and strength of recommendation using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach. A detailed description of background, methods, evidence summary and rationale that support each recommendation, and knowledge gaps can be found online in the full text.

Epidemiology and Management of Acute Hematogenous Osteomyelitis, Neonatal Osteomyelitis and Spondylodiscitis in a Third Level Paediatric Center.

Acute hematogenous osteomyelitis (AHOM) is a rare pathology in pediatric population. The aim of this study is to analyse the epidemiological data and the management, compared to European Society for Paediatric Infectious Disease (ESPID, European Society for Pediatric Infectious Diseases) guidelines 2017 of 216 children with AHOM, divided in three cohorts (neonatal-onset osteomyelitis, those with vertebral involvement and other types of osteomyelitis). We conducted a retrospective single center study, evaluating data from all the children (aged 0–18 years) consecutively admitted to the Meyer Children’s Hospital, during a period of ten years (1 January 2010–31 December 2019). Isolation of pathogen was possible in 65 patients and S. aureus was the most frequently involved (43/65 children). Magnetic Resonance Imaging (MRI, magnetic resonance imaging) was performed in 201/216 cases and was compatible with osteomyelitis in 185/201 of these children (92.03%). In the neonatal-onset osteomyelitis group the percentage of diagnostic ultrasound for osteomyelitis was 36.36% significantly higher than the other groups. The median duration of total antibiotic therapy was 37.5 days. In total, 186/199 children recovered without complications. The present study delineates three heterogeneous cohorts of patients. S. aureus is confirmed as the first pathogen for isolation in all three groups analysed. MRI represent a gold standard for diagnosis. Longer duration of antibiotics treatment was performed in neonatal and spondylodiscitis group, compared to the other types of osteomyelitis.

&lt;p&gt;Acute Hematogenous Osteomyelitis in Children: Clinical Presentation and Management&lt;/p&gt;

Acute hematogenous osteomyelitis (AHO) is a common invasive infection encountered in the pediatric population. In addition to the acute illness, AHO has the potential to create long-term morbidity and functional limitations. While a number of pathogens may cause AHO, Staphylococcus aureus is the most common organism identified. Despite the frequency of this illness, little high-quality data exist to guide providers in the care of these patients. The literature is reviewed regarding the epidemiology, microbiology and management of AHO in children. A framework for empiric therapy is provided drawing from the available literature and published guidelines.

The Role of Surgery in the Management of Acute Hematogenous Osteomyelitis

The Role of Surgery in the Management of Acute Hematogenous Osteomyelitis

Role of Operative or Interventional Radiology-Guided Cultures for Osteomyelitis.

Acute hematogenous osteomyelitis (AHO) is a severe infection in children. Drainage of purulent collections in bones provides specimens for culture as well as therapeutic benefit. Interventional radiology (IR)-guided procedures may serve as a less invasive means of culture in select patients. We examined the impact of IR and surgically obtained cultures in the diagnosis and management of AHO. A retrospective review of cases of AHO was performed from 2011 to 2014. Patients with chronic disease, orthopedic hardware, puncture wounds, or an infected contiguous focus were excluded. A total of 250 cases met inclusion criteria. Blood cultures were positive in 107 of 231 cases (46.3%), and 123 of 150 patients had positive cultures (82%) obtained by orthopedic surgery. Of these 123 patients, 62 (50.4%) had organisms identified only through operating room (OR) cultures. Of the 66 patients who had cultures obtained by IR, 34 (51.5%) had positive IR cultures. For those with positive IR cultures, 18 (52.9%) had negative blood cultures. Among the 80 patients with negative blood culture and positive OR/IR culture, the results changed antibiotic therapy in 68 (85%) patients. IR or OR culture was the only means of identifying a pathogen in 80 of 216 cases (37%), and in >80% changed medical management. IR can be used effectively to obtain bone cultures in children with AHO not requiring open surgical drainage. Further research is needed to better understand the optimal utilization of IR and OR culture in pediatric AHO.

Advances in the Diagnosis and Management of Pediatric Osteomyelitis

Acute hematogenous osteomyelitis is a common disease that affects previously healthy children of all age groups. Despite its importance, there are limited data in the current literature to guide many aspects of the diagnosis and therapy of this infection. Over the last decade, our understanding of the etiology of this infection has changed, with increased recognition of Kingella kingae and the dramatic increase in community-associated Methicillin-resistant Staphylococcus aureus (CA-MRSA) infections. There is a need for the optimization of diagnostic strategies, such as MRI and serum inflammatory markers. Several recent studies have examined treatment strategies, including a rapid transition to oral antimicrobial therapy and a shortened overall course of therapy. Many new therapeutic options are on the horizon that will likely impact the management of this and other childhood bacterial infections. This review summarizes recent investigations into the optimal diagnosis and management of acute hematogenous osteomyelitis in children.

Clinical Indications for Repeat MRI in Children With Acute Hematogenous Osteomyelitis

At our center and at others, some children with acute hematogenous osteomyelitis (AHO) are evaluated with multiple magnetic resonance imagings (MRIs) during their treatment. Do these serial MRI studies have a role in the management of AHO? We examine several clinical indications for ordering a repeat MRI and whether the imaging study resulted in a change in management. A total of 59 children (60 cases) with AHO were imaged with more than 1 MRI. We retrospectively reviewed the MRI studies and hospital records to investigate whether the results of the MRIs prompted a change in clinical management (surgical exploration or drainage, biopsy, change in the course of antibiotics). We investigated several clinical indicators including C-reactive protein (CRP) levels, time since index study, anatomic location of infection, and blood cultures. Differences in the proportion of patients with specified clinical characteristics, whose repeat MRI resulted in a change in management, were assessed by the use of χ² analysis. The median age of our patient population was 8.4 years; a total of 104 repeat MRI studies were undertaken on 59 children. Eleven (10.6%) of these studies prompted a change in patient treatment. Statistically significant indications for repeat MRI in changing clinical management included failure to improve clinically in 10 studies (21%, P<0.001), persistently elevated or increasing CRP levels in 11 MRI studies (52%, P<0.001), and the repeat study occurring within 14 days of the diagnostic MRI in 8 studies (29%, P=0.003). The results of our study showed that additional MRI studies provide information that affected patient management in only a limited number of cases. Although repeat MRI does not have a role in routine surveillance in children with AHO undergoing treatment, it can be a useful adjunct to clinical evaluation in patients who do not respond to therapy or who have a persistently elevated CRP level.

Management of acute hematogenous osteomyelitis in children

In children, osteomyelitis is primarily hematogenous in origin and acute in nature. The principal cause of osteomyelitis in children is Staphylococcus aureus, and both the epidemiology and pathogenesis of S. aureus infections, including osteomyelitis, have changed in recent years owing to the emergence of community-associated methicillin-resistant S. aureus. This review focuses on advances in the diagnosis and overall management of acute hematogenous osteomyelitis in children with these changes in mind.

Decline of Bone and Joint Infections Attributable to Haemophilus Influenzae Type b

Haemophilus influenzae has been a major cause of infectious diseases in children and has been attributed as a significant cause of septic arthritis and osteomyelitis in children. With the advent of widespread vaccination, the incidence of Haemophilus influenzae meningitis and other infections has been well documented. This is thought to be the first report that documents the effect of vaccination on bone and joint infections. One hundred sixty-five cases of acute hematogenous osteomyelitis or septic arthritis treated at the Department of Orthopaedics at Vanderbilt University in the years before and after the advent of the Haemophilus influenzae vaccine to assess whether vaccination affected the incidence of these diseases. The data indicate that the Haemophilus influenzae vaccine has reduced to near 0 the incidence of bone and joint infections because of Haemophilus influenzae. These findings suggest that coverage of Haemophilus influenzae as part of the empiric antibiotic coverage may be no longer needed in the management of acute hematogenous osteomyelitis and septic arthritis in children.

Pediatric Hematogenous Osteomyelitis: New Trends in Presentation, Diagnosis, and Treatment.

The character of acute hematogenous osteomyelitis (AHO) in North American children has changed significantly during the past several decades. Although the typical clinical picture of established acute osteomyelitis in children (illness, dehydration, and an acutely painful limb) is still seen, more subtle presentations appear more frequently. Children often present with subacute osteomyelitis. Less common variants include Brodie's abscess, subacute epiphyseal osteomyelitis, and chronic recurrent multifocal osteomyelitis. Some patients present with a bone lesion that may be confused with other disease entities, including neoplasms. Biopsy is often needed to clarify the diagnosis. With the trend toward more invasive procedures in the neonatal intensive care unit, neonatal osteomyelitis is also seen more frequently. Advances in imaging technology, particularly improvements in technetium bone scanning and the advent of magnetic resonance imaging, have contributed to more precise diagnosis and better management of AHO. With the increased concern about medical economics, the recent trend toward decreasing the duration of intravenous antibiotic treatment of these infections appears to be appropriate as long as certain criteria are met. Neither surgery nor antibiotics alone will be associated with successful treatment in all cases, and this fact may explain the rare but continued morbidity that is still seen in children with AHO.
