INTERNAL MEDICINE 54 ( 21 ) 2775 - 2777 2015年

記述言語：英語掲載種別：研究論文（学術雑誌）出版者・発行元：JAPAN SOC INTERNAL MEDICINE

We herein present a rare case of Actinomyces turicensis bacteremia that was caused by pyometra. The patient was successfully treated with transvaginal drainage and antibiotic therapy. A literature review in MEDLINE showed that there have been only 8 previously reported cases of A. turicensis bacteremia. This infection frequently occurs in patients with visceral abscesses, and blood culture examinations usually reveal a polymicrobial pattern. However, the prognosis of such patients has been reported to generally be benign. Due to difficulties in performing bacterial identification and the wide-spectrum clinical pictures associated with this bacteremia, no comprehensive understanding of the clinical features of each Actinomyces species has yet been established.

Objectives: Stenotrophomonas maltophilia shows wide-spectrum resistance to antimicrobials and causes various infections in immunocompromised or critically ill patients with high mortality. In this era of antibiotics resistance, a revival of old antibiotics is now featured. We examined the clinical usefulness of latamoxef (LMOX) for the treatment of S. maltophilia infection. Patients and methods: The observational study was retrospectively performed at Okayama University Hospital (Okayama, Japan) from January 2011 to December 2013. LMOX was administered to 12 patients with S. maltophilia infection, with eleven of those patients being admitted to the intensive care unit. Results: Underlying conditions of the patients included postoperation, hematological transplantation, hepatic transplantation, and burn. Major infectious foci were surgical site infection (six cases), respiratory infection (four cases), blood stream infection (three cases), and burn site infection (one case). The doses of LMOX administered ranged from 1 g/d to 3g d for ten adult patients and from 40 mg/kg/ d to 80 mg/kg/d for two pediatric patients. Microbiologic failure was seen in five (41.7%) of 12 cases, and 30-day and hospital mortality rates were 25% and 50%, respectively. Minimum inhibitory concentrations of LMOX were higher in the deceased group (4-64 mu g/mL) than in the surviving group (1-4 mu g/ mL). Conclusion: LMOX treatment is not recommended for the treatment of S. maltophilia infection. Further investigation would be needed before its clinical use.

A 34-year-old man with 22q11.2 deletion syndrome (DiGeorge syndrome) concurrently suffered from myopathy and eosinophilic pneumonia shortly after receiving daptomycin (DAP) for right-sided infective endocarditis. The simultaneous occurrence of these phenomena in relation to DAP therapy has not been previously well described. An allergic reaction was suspected as a possible etiology of these DAP-related complications. This case highlights the need for close observation in order to detect both musculoskeletal and respiratory disorders from the start of DAP therapy. Physicians should pay more attention to this new drug, which is expected to be frequently used in various clinical settings.

INTERNAL MEDICINE 54 ( 22 ) 2939 - 2941 2015年

記述言語：英語掲載種別：研究論文（学術雑誌）出版者・発行元：JAPAN SOC INTERNAL MEDICINE

We herein report a case of Klebsiella oxytoca-producing IMP-1 that was detected as a first isolate of carbapenem-resistant Enterobacteriaceae (CRE) at our facility. Since K. oxytoca is an uncommon strain for CRE, we speculated that the resistant organism had already spread out inside the hospital. Metallo-beta-lactamases promotes antibiotic resistance in Enterobacteriaceae, which potentially yields problematic issues in clinical settings. Active surveillance of antibiotic resistant strains is important and should be repeatedly highlighted. Furthermore, appropriate methods should be established to detect highly resistant strains.

記述言語：英語掲載種別：研究論文（学術雑誌）出版者・発行元：JAPAN SOC INTERNAL MEDICINE

We report a case of nephrostomy-associated urinary tract infection caused by Elizabethkingia meningoseptica that occurred in a patient with retroperitoneal fibrosis. Though conventional identification methods failed to detect the causative organism, it was identified on the basis of the complete sequencing of 16S rRNA. Four weeks of levofloxacin and minocycline administration successfully eradicated the infection. E. meningoseptica rarely causes urinary tract infections, and we believe that this is the first such case in which the isolate was genetically confirmed. The accurate identification of the organism is necessary for the provision of appropriate treatment and to obtain a better understanding of its epidemiology and pathogenicity.

A 67-year-old man with a persistent high fever was diagnosed to have an infective aneurysm in his left internal iliac artery. A blood culture detected a gram-negative spiral rod that was first identified as Campylobacter fetus subsp. venerealis based on a matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS) analysis. However, the strain was finally confirmed to be Campylobacter fetus subsp. fetus based on a genetic analysis. The infection was successfully treated with emergency resection of the aneurysm, followed by 4 weeks of antibiotic therapy. Involvement of the peripheral artery is uncommon in cases of C. fetus-infective aneurysm. To figure out the epidemiology and pathogenicity of C. fetus infection, the accurate identification of the responsible organisms is essential.

We herein describe the first reported case of pyogenic spondylitis and diskitis caused by Helicobacter cinaedi. The results of magnetic resonance imaging and the histology of biopsied tissue were suggestive of acute infection at the lumbar spine. The pathogen was obtained by a blood culture examination and identified by 16S rRNA analysis. Eight weeks of antibiotics therapy resulted in a good clinical course. H. cinaedi infections have been increasingly reported in recent years, but the pathogen's epidemiological and pathological characteristics are still unclear. One of the difficulties in understanding the pathogenesis of H. cinaedi has been the challenges in cultivating the pathogen. Novel strategies for the diagnosis of H. cinaedi must be developed.

We herein report a heterosexual Japanese man in his forties who had been suffering from advanced dementia and personality change for 4 years. Positive results of a serological test for syphilis, Treponema pallidum hemagglutination assay, and fluorescent treponemal antibody-absorption test of both serum and cerebral spinal fluid led to the diagnosis of neurosyphilis. Jarisch-Herxheimer reaction was seen shortly after the first dose of penicillin was administered to the patient. His cognitive function did not recover after treatment. The incidence of syphilis has been reported to be increasing. Neurosyphilis should not be overlooked as an etiology for progressive dementia even in this post-antibiotic era.

A 53-year-old man with a past medical history of total arch replacement surgery and severe aortic regurgitation presented with a 1-month history of persistent general malaise, anorexia, body weight loss and night sweats. His recent history included gingival hyperplasia for 6 years, gingivitis after tooth extraction 3 years before, prolonged inflammatory status for 4 months, fundal hemorrhage and leg tenderness for 2 months. A pathogen was detected from blood culture, but conventional microbiological examination failed to identify the pathogen. The organism was eventually identified as Cardiobacterium valvarum by 16S rRNA analysis, and the patient was diagnosed with infective endocarditis and prosthetic vascular graft infection. The patient received intravenous antibiotic therapy using a combination of ceftriaxone and levofloxacin for 5 weeks and was discharged with a good clinical course.
C. valvarum is a rare human pathogen in clinical settings. Only 10 cases have been reported to date worldwide, and therefore, the clinical characteristics of C. valvarum infection are not fully known. This is a first well-described case of C. valvarum infection in Japan, and further, a first report of aortic prosthetic vascular graft infection worldwide. Identification of C. valvarum is usually difficult due to its phenotypic characteristics, and molecular approaches would be required for both clinicians and microbiologists to facilitate more reliable diagnosis and uncover its clinical picture more clearly.
