First reported case of vertebral osteomyelitis due to Erysipelothrix rhusiopathiae

Disseminated Erysipelothrix rhusiopathiae with Secondary Prosthetic Hip Joint Infection: A Case of Successful Identification and Management in a Regional Hospital

CASE

This article reports a case of a 72-year-old man with bilateral total hip joint replacements who suffered cuts to his hands while butchering a wild boar. He presented to the emergency department with fevers and unilateral hip pain. Erysipelothrix rhusiopathiae (E. rhusiopathiae) was isolated on hip aspirate and blood cultures. E. rhusiopathiae is a well-recognized zoonotic infection in humans, particularly in at-risk hosts, most commonly infecting swine. Infection is spread by ingestion or through skin abrasion.

CONCLUSION

This illustrates an example of successful operative and perioperative management of prosthetic joint infection secondary to E. rhusiopathiae, particularly microbiological identification, within a multispecialty team of physicians and surgeons.

[Sacroiliitis with Erysipelothrix Rhusiopathiae revealing tricuspid endocarditis, the first case reported on the Guiana Shield: clinical case and review of the literature]

We report here an atypical case of acute sacroiliitis caused by Erysipelothrix rhusiopathiae revealing tricuspid endocarditis in a 53-year-old woman without medical history. She was admitted to Cayenne hospital because of intense right hip and thigh pain, associated with fever. A right sacroiliitis was visible on the computed tomography (CT) scan, confirmed on MRI. Transesophageal echocardiography revealed a large mobile tricuspid vegetation. Blood cultures were positive for E. rhusiopathiae. CT scan showed pulmonary alveolar opacities, consistent with septic emboli. Clinical improvement was obtained under ceftriaxone followed by ciprofloxacin for 6 weeks of treatment. We present a review of bone and joint infections caused by E. rhusiopathiae. So far, not a single case has been reported in Latin America.

Clinical manifestations, associated diseases, diagnosis, and treatment of human infections caused by Erysipelothrix rhusiopathiae: a systematic review

INTRODUCTION

Erysipelothrix rhusiopathiae is a bacillus that can cause cutaneous and systemic diseases in humans. Studies on the infection caused by this bacterium have been mostly done as case reports. This study aimed to systematically review E. rhusiopathiae infection cases published over the last 20 years.

METHODS

Science Direct, PubMed, Scopus, Google Scholar, and Web of Science were searched using appropriate keywords to find relevant studies. After assessment of the studies, 57 case reports which surveyed 62 patients were included and their data were collected and analyzed.

RESULTS

The majority of cases were adult men living in high-income countries with an animal-related job and/or a history of animal contacts. The number of cases has increased in recent years. The main underlying diseases that were associated with E. rhusiopathiae infections include hypertension, diabetes, and alcoholism. The most frequent presentations were fever, pain, local skin lesions, and heart failure/endocarditis. Two patients died, while 60 patients were recovered following antibiotic therapy, mainly with penicillin and ceftriaxone.

CONCLUSIONS

Altogether, the results indicated that E. rhusiopathiae usually infects people who come into contact with animals and causes mild to severe local or systemic infections, especially in those who have underlying diseases. Therefore, accurate and early diagnosis of E. rhusiopathiae infections by setting up appropriate laboratory tests is required.

Osteoarticular Infections Caused by Erysipelothrix rhusiopathiae: Case Report and Literature Review

We present a case of Erysipelothrix rhusiopathiae spondylodiscitis in an otherwise healthy man, occurring 1 year after exposure. The patient was cured after 6 weeks of treatment with amoxicillin followed by ciprofloxacin without surgery. Erysipelothrix rhusiopathiae can cause severe osteoarticular infections with a delayed presentation following exposure to the pathogen.

Erysipelothrix rhusiopathiae endocarditis

Erysipelothrix rhusiopathiae is a zoonotic gram positive coccobacillus. It is rarely found in humans as an occupational pathogen that mainly infects animal handlers. There are three forms of human infection: localized erysipeloid, diffuse cutaneous form and lastly, bacteremia that could progress to infective endocarditis. We present a case of a 59-year-old male who was found to have E. rhusiopathiae bacteremia that was diagnosed as aortic valve endocarditis with severe aortic regurgitation. The patient was treated with ampicillin-sulbactam then transitioned to six weeks of intravenous ampicillin. This report summarizes a rare organism that causes a serious human infection and discusses its epidemiology, clinical presentation, diagnosis and treatment options.

Native valve endocarditis caused by E rysipelothrix Rh usiopathiae: presenting with refractory heart failure and requiring surgical valve replacement-report on a rare zoonosis

Erysipelothrix Rhusiopathiae is a Gram-positive bacillus that is ubiquitous in nature. The bacterium is a zoonotic pathogen known to infect wild and domestic animals. Human infections, however, are uncommon and typically present with localised or generalised cutaneous lesions. Systemic infection in the form of bacteraemia with seeding to various organs is the least common form of the disease. Infections in humans tend to be associated with occupational exposure and close contact with animals. Clinical data of a 61-year-old male patient with Gram-positive bacilli bacteraemia and E. Rh usiopathiae-induced endocarditis are presented here. The patient presented with refractory congestive heart failure secondary to severe acute aortic regurgitation mandating surgical valve replacement. The described case has special clinical merit given the lack of fever and leukocytosis, absence of erysipeloid cutaneous manifestations and refractoriness to medical management. E. Rhusiopathiae should be considered in the differential diagnosis for Gram-positive bacilli bacteraemia and endocarditis. In the proper clinical setting, occupational exposure and animal contacts are helpful clues to raise suspicion for this bacillus. The high mortality associated with the pathogen should urge for early identification and initiation of antimicrobial treatment.

Mycobacteriumabscessus-associated vertebral osteomyelitis in an immunocompetent patient: a rare case report and literature review

Introduction

Vertebral osteomyelitis (VO) is an uncommon infection with Staphylococcus aureus as the most commonly implicated organism. VO caused by nontuberculous mycobacteria (NTM) such as Mycobacteriumabscessus (M. abscesscus) is exceedingly rare with only eight cases reported in literature.

Case presentation

We report a rare case of an 82-year-old male with a remote history of trauma who was diagnosed with NTM vertebral osteomyelitis. The patient initially underwent a vertebroplasty of T12 and kyphoplasty of L1 for pathologic compression fractures. Subsequent cultures revealed M. abscessus. The patient further underwent an anterior T12-L2 corpectomy and debridement with instrumented fusion, as well as a posterior T9-L4 instrumentation and fusion. He received multi-agent antibiotic therapy; however, was ultimately unable to tolerate the aggressive treatment regimen and his prolonged postoperative course.

Discussion

Nontuberculous mycobacteria vertebral osteomyelitis is exceedingly rare. NTM vertebral osteomyelitis is challenging to treat. Surgical management plays a limited role in early VO, but is the mainstay treatment in chronic VO. Early recognition of the condition and shared patient management with multidisciplinary teams is key to successfully treating cases of NTM VO.
