Skipped vertebral spontaneous spondylodiscitis caused by Granulicatella adiacens: Case report and a systematic literature review.

ABSTRACT:

Background

Granulicatella adiacens is a nutritional variant of streptococcus (NVS), which has been rarely reported as an etiologic agent in spondylodiscitis (SD).

Material and methods

We report a case of a 51-year-old male with from chronic low-back pain associated with right sciatica and ipsilateral monoparesis. Spinal MRI showed radiological signs on L1-L2 and L5-S1 discs consistent with SD. We also performed a systematic review of the pertinent literature in order to retrieve all the key information regarding microbiological and clinical features.

Results

Including our patients, seven cases with a mean age 56 ± 10.2 years were reported in English literature. Six patients were conservatively managed with antibiotic therapy (66%), whereas three with surgery in combination with antibiotics (33%). An endocarditis was associated in three cases, and a pacemaker infection in one. All patients received targeted antibiotic therapy resulting in a quick improvement of clinical symptoms with favorable outcome. Our case is the only with a skip spontaneous SD, which needed a surgical decompression due to the associated neurological symptoms.

Conclusions

This incidence of SD sustained by Granulicatella adiances could be underestimated due to their particular microbiological conditions requested for their cultures. However, this infection should be suspected in cases of culture-negative SD, especially when associated with endocarditis.

Gouty spondylodiscitis with lumbar vertebral body retrolisthesis: A case report.

Project description:RationaleGout occurs mainly in joints, but rarely in the spine. In the spine, urate crystals can cause intervertebral space instability but rarely lead to retrolisthesis. Here, we present an extremely rare disease with gout invaded the intervertebral disc with lumbar retrolisthesis.Patient concernsA 61-years male patient with gout history has suffered from severe low back pain and intermittent claudication. Physical examination showed the level of muscle strength of his left first toe was 3/5. Images illustrated a destruction of the intervertebral space, and a retrolisthesis at L4/5 interspace and the dural sac obviously compressed.DiagnosesCombining with lab examinations, imaging examinations, and histopathological results, the patient was diagnosed with gouty arthritis associated with lumbar spinal stenosis, L4-5 spondylodiscitis and L4 vertebral body retrolisthesis.InterventionThe patient underwent posterior decompression, reduction, and interbody fusion, and then received an aggressive postoperative rehabilitation program.OutcomesThe patient's low back pain was significantly alleviated after the operation. Postoperative X-ray shows the internal fixation was well placed and the sequence of spine was reconstructed. 12 weeks later, the lower limb symptoms of the patients were obviously improved, his muscle strength of the left first toe was 4/5, Japanese Orthopaedic Association (JOA) score was 19 and the improvement rate was 61.5%.LessonsGouty spondylodiscitis can cause intervertebral space instability. Sagittal imbalance and degeneration of disc with decreasing of segmental disc height are considered as the main factors of retrolisthesis. The appearance may lead to misdiagnose a patient with gout history with a destruction of the intervertebral space. Surgery is a compromise method for gouty spondylodiscitis patients with urgent neurological symptoms.

Aortic Endograft Infection with Mycobacterium chimaera and Granulicatella adiacens, Switzerland, 2014.

Project description:We describe an aortic endograft infection caused by Mycobacterium chimaera and Granulicatella adiacens, successfully treated with prolonged antimicrobial drug therapy after complete explantation of the infected endoprosthesis and extra-anatomical reconstruction. Whole-genome sequencing analysis did not indicate a close relationship to bacterial strains known to cause infections after cardiac surgery.

Proteomic Analysis and Virulence Assessment of <i>Granulicatella adiacens</i> Secretome.

Project description:Despite reports on the occurrence of Granulicatella adiacens in infective endocarditis, few mechanistic studies on its virulence characteristics or pathogenicity are available. Proteins secreted by this species may act as determinants of host-microbe interaction and play a role in virulence. Our aim in this study was to investigate and functionally characterize the secretome of G. adiacens. Proteins in the secretome preparation were digested by trypsin and applied to nanoLC-ESI-MS/MS. By using a combined mass spectrometry and bioinformatics approach, we identified 101 proteins. Bioinformatics tools predicting subcellular localization revealed that 18 of the secreted proteins possessed signal sequence. More than 20% of the secretome proteins were putative virulence proteins including serine protease, superoxide dismutase, aminopeptidase, molecular chaperone DnaK, and thioredoxin. Ribosomal proteins, molecular chaperones, and glycolytic enzymes, together known as "moonlighting proteins," comprised fifth of the secretome proteins. By Gene Ontology analysis, more than 60 proteins of the secretome were grouped in biological processes or molecular functions. KEGG pathway analysis disclosed that the secretome consisted of enzymes involved in biosynthesis of antibiotics. Cytokine profiling revealed that secreted proteins stimulated key cytokines, such as IL-1β, MCP-1, TNF-α, and RANTES from human PBMCs. In summary, the results from the current investigation of the G. adiacens secretome provide a basis for understanding possible pathogenic mechanisms of G. adiacens.

Enhanced propagation of Granulicatella adiacens from human oral microbiota by hyaluronan.

Project description:Host determinants for formation/composition of human oral microbiota remain to be clarified, although microorganisms entering the mouth cannot necessarily colonize the oral environment. Here we show that human oral-abundant bacteria degraded host glycosaminoglycans (GAGs) in saliva and gingiva, and certain bacteria significantly grew on hyaluronan (HA), a kind of GAGs. Microbial communities from teeth or gingiva of healthy donors assimilated HA. Metagenomic analysis of human oral microbiota under different carbon sources revealed HA-driven Granulicatella growth. HA-degrading bacterial strains independently isolated from teeth and gingiva were identified as Granulicatella adiacens producing extracellular 130 kDa polysaccharide lyase as a HA-degrading enzyme encoded in a peculiar GAG genetic cluster containing genes for isomerase KduI and dehydrogenase DhuD. These findings demonstrated that GAGs are one of the host determinants for formation/composition of oral microbiota not only for colonization but also for the adaptation to the host niche. Especially, HA enhanced the G. adiacens propagation.

Vestibular paroxysmia caused by contralateral tortuous vertebral artery: A case report.

Project description:RationaleVestibular paroxysmia (VP) is characterized by spontaneous, recurrent, short, paroxysmal attacks of vertigo with or without tinnitus.Patient concernsWe report a case of paroxysmal recurrent vertigo accompanying clicking tinnitus on the left side in a 61-year-old patient. He had undergone microvascular decompression to treat the left-side hemifacial spasm 6 years prior. The patient first developed vertigo attacks about 3 years after microvascular decompression, and the attacks increased in frequency over the last 4 months. Video-nystagmography revealed a background right-beating nystagmus which was reversed every 55 seconds, to left-beating nystagmus for 17 seconds.DiagnosisBrain magnetic resonance imaging and angiography demonstrated a compression of the cisternal segment of the left vestibulocochlear nerve between the tortuous right vertebral artery and the posterior wall of the left porus acusticus internus.Interventions and outcomesUnder the diagnosis of VP, 300 mg oxcarbazepine was administered daily, which relieved the symptoms dramatically.LessonThe neurovascular cross-compression of the vestibulocochlear nerve by the contralateral vertebral artery tortuosity can cause VP. Periodic paroxysms of right-beating nystagmus accompanying the left-side tinnitus during vertigo attacks in our patient can be explained by secondary central hyperactivity in both vestibular and cochlear nuclei following long-standing neurovascular cross-compression.
