A 93-year-old woman was diagnosed with Lysinibacillus fusiformis bacteremia complicated with coma blisters. Initial gram staining for L. fusiformis indicated the presence of gram-negative rods; however, subsequent staining of colonies from Mueller-Hinton agar revealed the presence of gram-positive and gram-negative rods with spherical endospores, and Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (VITEK ® MS and microflex® LT/SH) definitively identified the organism as L. fusiformis. The two-week administration of piperacillin/tazobactam and ampicillin resulted in an improvement of the patient's general condition, and the skin lesions gradually improved.

We herein report a 59-year-old woman with a 2-year history of chronic bursitis of the hand who took 50 mg/day prednisolone for several autoimmune diseases. Mycobacteroides abscessus subsp. massiliense was isolated from the abscess and blood culture. Combination therapy (imipenem/cilastatin, amikacin, and clarithromycin) was administered for a month. Two months later, M. massiliense was detected from a blood culture again, and disseminated lesions were found. Clarithromycin and sitafloxacin were administered following eight weeks of the same regimen. Six months after the diagnosis, M. massiliense was isolated from a blood culture, and she expired due to multiple organ failure.

Acquired Fanconi Syndrome in a Patient with Nontyphoidal Salmonella Bacteremia. Open Access

Akihiro Ryuge, Shoji Saito, Hiroshi Morioka, Asaka Hachiya, Noritoshi Kato, Takuji Ishimoto, Tomoki Kosugi, Shoichi Maruyama

Internal medicine (Tokyo, Japan) Vol. 60 ( 5 ) page： 761 - 764 2021

Language：Japanese Publishing type：Research paper (scientific journal) Publisher：The Japanese Society of Internal Medicine

Nontyphoidal Salmonella is a common cause of bacterial gastroenteritis, occasionally causing bacteremia. We herein report the case of an 80-year-old man who presented with bacteremia and pre-renal acute kidney injury (AKI) secondary to diarrhea caused by nontyphoidal Salmonella. Despite AKI improvement on fluid administration, some serological abnormalities, such as hypokalemia, hypophosphatemia, and hypouricemia, and abnormal urinary findings emerged, including renal glycosuria and aminoaciduria. Fractional excretion of phosphate and uric acid was increased, suggesting that the serological and urinary abnormalities may have arisen from Fanconi syndrome. Physicians should consider acquired Fanconi syndrome when patients with nontyphoidal Salmonella bacteremia present with electrolyte disorders.

Journal of infection and chemotherapy : official journal of the Japan Society of Chemotherapy Vol. 25 ( 3 ) page： 215 - 217 2019.3

Publishing type：Research paper (scientific journal)

The reported number of transcatheter aortic valve replacement-associated infective endocarditis (TAVR-IE) cases has been increasing worldwide, but information about the incidence and clinical features of fungal TAVR-IE is quite limited. We present a patient who acquired TAVR-IE caused by Candida parapsilosis four month after TAVR, who was successfully treated redo-aortic valve replacement and prolonged antifungal therapy.

Active surveillance in response to the identification of a single carbapenemase-producing Escherichia coli at a Japanese university hospital. International journal

Publishing type：Research paper (scientific journal) Publisher：Elsevier B.V.

This report described the experience of active surveillance culture implemented in response to the identification of a single carbapenemase-producing Escherichia coli in a Japanese university hospital. It revealed a horizontal transmission event and an additional asymptomatic carrier of carbapenemase-producing Escherichia coli with unique drug susceptibility and resistance gene profiles. Early implementation of active surveillance culture as a part of multifaceted infection control measures appeared to be useful to control further transmission of carbapenemase-producing Escherichia coli even in the low endemic facility. Further investigations on the timing and usefulness of active surveillance culture in the control of carbapenemase-producing Enterobacteriaceae would be warranted.

BACKGROUND: Point prevalence surveys (PPSs) in Japanese hospitals have not yet been reported. The purpose of this pilot PPS study was to evaluate the epidemiology of health care-associated infections (HAIs) and antimicrobial use in a Japanese tertiary university hospital. METHODS: A 1-day, cross-sectional PPS was performed at a Japanese university hospital. Data on demographics, active HAIs, and antimicrobial use of all inpatients were collected using a data collection form. RESULTS: Of 841 patients, 85 (10.1%) had 90 active HAIs, and 308 patients (36.6%) were administered 494 antimicrobials. Among the 90 HAIs and 58 pathogens, the most frequent infection and isolated pathogen were pneumonia (20.0%) and Enterobacteriaceae (27.6%), respectively. Of the 118 antimicrobials used for treatment of HAIs, carbapenems were the most frequently administered category of antimicrobials (22.9%). In regard to antimicrobials for surgical prophylaxis, 37 of 119 (31.1%) were administered to patients on postoperative day 3 or later, and 48 of 119 (40.3%) were administered orally. CONCLUSIONS: The incidence of HAIs is higher than in other developed countries. The social and medical situation in Japan may affect patient demographics, active HAIs, and antimicrobial use. Multicenter PPSs are necessary to uncover the real epidemiology of HAIs and antimicrobial use in Japan.

Publishing type：Research paper (scientific journal)

We herein report a 52-year-old man infected with human immunodeficiency virus (HIV) who was referred to our hospital due to the development of severe neurocognitive disorders and bilateral leukoencephalopathy. He has been treated with antiretroviral agents for 17 years, but low-level viremia has been detected consistently prior to admission. Drug resistant testing of the serum and the cerebrospinal fluid (CSF) both demonstrated a M184V mutation. A brain biopsy revealed perivascular CD8(+) T-lymphocyte infiltration, leading to the diagnosis of CD8 encephalitis. The clinical symptoms improved drastically after changing to a nucleoside reverse transcriptase inhibitor sparing regimen, which subsequently decreased the HIV viral load to an undetectable level in both the serum and CSF.
