Vogesella urethralis-induced aspiration pneumonia and bacteremia in an elderly man: a first case report and literature review.

ABSTRACT:

Background

Vogesella species are common aquatic Gram-negative rods that were first reported in 1997. Vogesella urethralis bacterium was first isolated from human urine in 2020. Only two cases of disease caused by Vogesella species have been reported with no case of Vogesella urethralis-caused disease being reported as yet. Herein, we report a case of aspiration pneumonia and bacteremia caused by Vogesella urethralis.

Case presentation

An 82-year-old male patient was admitted with dyspnea, increased sputum production, and hypoxia. Gram-negative rods were isolated from the blood and sputum cultures of the patient. He was diagnosed with aspiration pneumonia and bacteremia. Initially, Vogesella urethralis was wrongly identified as Comamonas testosteroni based on fully automated susceptibility testing; however, additional 16S rRNA gene sequencing identified the causative as Vogesella urethralis. The patient was treated with piperacillin and tazobactam. Unfortunately, he developed aspiration pneumonia again and died during hospitalization.

Conclusions

Since no database exists for rare bacteria in traditional clinical microbiology laboratories, 16S rRNA gene sequence analysis is useful. We report the first case of Vogesella urethralis-induced aspiration pneumonia and bacteremia.

Project description:IntroductionInjection laryngoplasty is a common procedure for patients with vocal fold dysfunction, but the literature on its benefits has been mainly focused on those related to structural lesions or laryngeal nerve involvement. Stroke patients may be at increased risk of aspiration due to insufficient vocal fold motion. However, how injection laryngoplasty can be of benefit in stroke patients has not been reported yet.Patient concernsSix chronic stroke patients with long-standing swallowing difficulties and who showed severe aspiration despite long-term swallowing rehabilitation.DiagnosisLaryngoscope evaluation revealed insufficient glottic closure as the cause of aspiration.InterventionsInjection laryngoplasty was done per-orally under local anaesthesia with calcium hydroxylapatite (Radiesse Voice, 1-1.5 mL) in an office setting. Respiratory pressures and peak cough flows were assessed at baseline and at 2 weeks follow-up.OutcomesAt 2 weeks, the mean peak cough flow (Δ = +95.09 L/min) increased significantly after the procedure. The maximal expiratory (Δ = +18.40 cm H2O) and inspiratory (Δ = +20.20 cm H2O) pressures also improved, indicating that injection laryngoplasty was effective in augmenting respiratory and cough parameters. All cases showed improvement in the Functional Oral Intake Scale (Δ = +4). Feeding tubes were successfully removed.ConclusionInjection laryngoplasty proved to be both successful and safe in improving glottic closure with immediate results in those who had failed to show a positive response after long-term swallowing rehabilitation. The positive and dramatic clinical outcomes were observed through changes in the coughing force. Our case series support the use of injection larygnoplasty as a powerful adjunctive treatment method to prevent aspiration pneumonia in post-stroke patients with vocal fold insufficiency. Pre- and post-injection peak cough flow changes may reflect improvement in glottic closure and indicate the safety of swallowing with reduced risk of aspiration.
