Reviving Sternheimer stain: A single-center retrospective study to detect the diagnostic utility of urinary tract infections in the emergency department. J Infect Chemother 2024; 30:768-772. [PMID: 38387786 DOI: 10.1016/j.jiac.2024.02.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Revised: 01/26/2024] [Accepted: 02/19/2024] [Indexed: 02/24/2024]
Abstract
INTRODUCTION Qualitative urinalysis using the Sternheimer stain is a common method in Japan for identifying bacteriuria, but there is a lack of studies examining its test characteristics. In this study, we aimed to investigate the sensitivity and specificity of the Sternheimer stain for urine culture results and compare it with the sensitivity and specificity of the Gram stain. Our goal was to determine the usefulness of the Sternheimer stain in identifying bacteriuria. PATIENTS AND METHODS Among 986 patients aged 16 years or older from whom samples for both urinalysis and urine culture were obtained at the emergency room of Tenri Hospital from January 2019 to December 2019, 342 patients with pyuria, defined as the presence of 10 or more white cells per cubic millimeter in a urine specimen, who had not received prior antimicrobial therapy were included. Urine cultures were used for comparison to determine the sensitivity and specificity of Sternheimer and Gram stain in this patient group. A positive Sternheimer stain result was defined as bacteriuria ≥ (1+), and that of Gram stain was defined as ≥ 1/1 field of high-power ( × 1000) oil immersion. RESULTS Using urine culture results for comparison, the sensitivity of Sternheimer stain was 92.2%, the specificity was 48.5%, the positive likelihood ratio was 1.79, and the negative likelihood ratio was 0.16. DISCUSSION Sternheimer stain is a rapid and useful method to exclude bacteriuria in a group of patients with pyuria in the emergency department.

Abstract
Emphysematous pyelonephritis (EPN) is a necrotizing bacterial infection characterized by gas retention and a poor prognosis. We present the case of a 75-year-old man who was diagnosed early with EPN and received multidisciplinary treatment. He had poorly controlled type 2 diabetes mellitus (DM) and chronic kidney disease (CKD), and was treated with oral hypoglycemic drugs, including a sodium-glucose co-transporter-2 inhibitor. He experienced the onset of back pain in the midsection of his back, tenderness in the costovertebral angle, and a high fever (> 39 °C), accompanied by tachycardia, hypotension, and tachypnea. The patient was diagnosed with pyelonephritis and septic shock. Immediate measures encompassing empirical antibiotic therapy, administration of noradrenaline, blood glucose regulation, and urethral catheterization were implemented. However, due to the persistent fever (> 38 °C) and lack of improvement in his condition, abdominal computed tomography (CT) was repeated on the fourth day. This revealed the presence of gas around the right kidney parenchyma, leading to a diagnosis of EPN that had evolved from acute pyelonephritis. Subsequently, percutaneous drainage of the right kidney parenchyma was performed. Subsequently, multidisciplinary treatment was continued, and his condition gradually improved. Clinicians should evaluate abdominal CT when acute pyelonephritis does not improve within a few days of antibiotic therapy. Disease progression from acute pyelonephritis to EPN should be considered in patients with DM and CKD.

Abstract
Uncomplicated cystitis is affecting many women of all ages and has a great impact on the quality of life, especially in women suffering from recurrent, uncomplicated cystitis. By far the most frequent uropathogen, E. coli, may have acquired increasing resistance against a variety of oral antibiotics, which may differ between countries and regions. Therefore, local resistance data are important to be considered. On the other hand, non-antibiotic therapy has also become an option which should be discussed and offered to the patient. In patients suffering from recurrent uncomplicated cystitis, individual risk factors and possible behavioral changes should first be taken into account. Non-antimicrobial prophylactic strategies shown to be successful in well-designed clinical studies are the next options. Long term antibiotic prophylaxis, however, should only be considered as a last option. For some of those patients self-diagnosis and self-treatment may be suitable, e.g. by using a recognized questionnaire.

Abstract
The Japanese surveillance committee conducted a third nationwide surveillance of antimicrobial susceptibility of acute uncomplicated cystitis at 55 facilities throughout Japan between April 2020 and September 2021. In this surveillance, we investigated the susceptibility of Escherichia coli (E. coli), Klebsiella pneumoniae (K. pneumoniae), and Staphylococcus saprophyticus (S. saprophyticus) for various antimicrobial agents by isolating and culturing bacteria from urine samples. In total, 823 strains were isolated from 848 patients and 569 strains of target bacteria, including E. coli (n = 529, 92.9 %), K. pneumoniae (n = 28, 4.9 %), and S. saprophyticus (n = 12, 2.2 %) were isolated. The minimum inhibitory concentrations of 18 antibacterial agents were determined according to the Clinical and Laboratory Standards Institute manual. In premenopausal patients, there were 31 (10.5 %) and 20 (6.8 %) fluoroquinolone (FQ)-resistant E. coli and extended-spectrum β-lactamase (ESBL)-producing E. coli, respectively. On the other hand, in postmenopausal patients, there were 75 (32.1 %) and 36 (15.4 %) FQ-resistant E. coli and ESBL-producing E. coli, respectively. The rate of FQ-resistant E. coli and ESBL-producing E. coli in post-menopausal women was higher than that for our previous nationwide surveillance (20.7 % and 32.1 %: p = 0.0004, 10.0 % and 15.4 %; p = 0.0259). For pre-menopausal women, there was no significant difference in the rate of FQ-resistant E. coli and ESBL-producing E. coli between this and previous reports, but the frequency of FQ-resistant E. coli and ESBL-producing E. coli exhibited a gradual increase. For appropriate antimicrobial agent selection and usage, it is essential for clinicians to be aware of the high rate of these antimicrobial-resistant bacteria in acute uncomplicated cystitis in Japan.

Abstract
One complication of cutaneous ureterostomy is urinary stone formation, which may lead to recurrent pyelonephritis. Frequent catheter changes and the prophylactic administration of antibiotics are commonly used to prevent stone formation. Cranberry products have been reported to inhibit stone formation in indwelling urethral catheters. We herein examined the inhibitory effects of a cranberry product on stone formation in a case of catheter occlusion due to stone formation after cutaneous ureterostomy. The results obtained indicate the potential of cranberry products to prevent stone formation after cutaneous ureterostomy requiring catheter placement.

Abstract
INTRODUCTION This study compares the clinical and microbiological efficacy of ceftolozane/tazobactam (CTLZ/TAZ) and piperacillin/tazobactam (PIPC/TAZ) for treating complicated cystitis or acute pyelonephritis. METHODS Patients who had been treated with empiric antibiotics, CTLZ/TAZ (52 cases) or PIPC/TAZ (47 cases), due to urinary tract infections (UTIs) were eligible for this study. Patients' demographic backgrounds, types of UTIs, and causative microorganisms isolated from urine or blood bacterial cultures were collected. Short-term clinical efficacy at the end of the initial empiric therapy, long-term clinical efficacy including sequential antibiotic treatments (nonrecurrence rate within 1 month after the initial empiric therapy), and microbiological efficacy were retrospectively compared in both CTLZ/TAZ and PIPC/TAZ groups. RESULTS Complicated UTIs were present in most eligible patients, and no significant difference in the patients' background was observed between the two groups. Escherichia coli and Enterococcus faecalis were the most common microorganisms isolated from urine culture in both groups. The short-term clinical effective rate of CTLZ/TAZ and PIPC/TAZ was 80.8% and 87.2%, respectively. For long-term clinical efficacy, the nonrecurrence rate of UTIs was present in 95.1% and 89.7% of patients with CTLZ/TAZ and PIPC/TAZ, respectively. No significant difference was observed in the short- and long-term effects between the two groups. The microbiological efficacy of the CTLZ/TAZ and PIPC/TAZ groups was 72.7% and 86.0%, respectively. No significant difference in microbiological effects was also observed between the two groups. CONCLUSIONS This study demonstrated the noninferiority of CTLZ/TAZ to PIPC/TAZ, suggesting that CTLZ/TAZ is an alternative antibiotic used as empiric therapy for UTIs.

Abstract
Objectives We aimed to prospectively compare lower urinary tract symptoms in premenopausal and postmenopausal women with acute uncomplicated cystitis before and after antibiotic therapy. Materials and methods This study included adult women with acute uncomplicated cystitis who visited 4 institutions between 2019 and 2020. After registration, we administered oral antibiotics and prospectively documented the changes in lower urinary tract symptoms from the first visit to a follow-up visit at 1 week using the Core Lower Urinary Tract Symptoms Score (CLSS) questionnaire. Results After treatment, pyuria disappeared in 60 of the 66 patients (14 premenopausal and 46 postmenopausal). The CLSS total score (range) changed from 13 (3-29) to 4 (0-18) with a significant improvement in all CLSS items. At baseline, nocturia, urgency, and urgency incontinence were more prominent in postmenopausal women than in premenopausal women. In contrast, baseline urethral pain and quality of life index were more severe in premenopausal women than in postmenopausal women. After treatment, the CLSS total score was still higher in postmenopausal women, as reflected by the relatively higher scores for nocturia and urgency, irrespective of the comparable scores for urethral pain and the quality of life index in the 2 groups. Conclusions Our results suggest that if storage symptoms persist, they should be carefully interpreted according to menopausal status.

Abstract
INTRODUCTION Gram staining is a convenient method for bacterial estimation. Urine culture is typically used to diagnose urinary tract infections. Therefore, urine culture is also performed on Gram stain-negative urine specimens. However, the frequency of uropathogen identification in these samples remains unclear. METHODS From 2016 to 2019, we retrospectively compared the results of Gram staining and urine culture tests on midstream urine specimens submitted for the diagnosis of urinary tract infections to confirm the significance of urine culture on Gram stain-negative specimens. Analysis was performed according to the patients' sex and age, and the frequency of uropathogen identification in the culture was examined. RESULTS A total of 1763 urine specimens (women, 931; men, 832) were collected. Of these, 448 (25.4%) were not positive on Gram staining but were positive on culture. In specimens without bacteria on Gram staining, the frequencies of specimens with uropathogens detected on culture were 20.8% (22/160) in women aged <50 years, 21.4% (71/332) in women aged ≥50 years, 2.0% (2/97) in men aged <50 years, and 7.8% (39/499) in men aged ≥50 years. CONCLUSIONS In men aged <50 years, the frequency of uropathogenic bacteria identification by urine culture was low in Gram stain-negative specimens. Therefore, urine cultures may be excluded from this group. In contrast, in women, a small number of Gram stain-negative specimens showed significant culture results for the diagnosis of urinary tract infection. Therefore, urine culture should not be omitted in women without careful consideration.

Abstract
BACKGROUND The management of adult male urinary tract infections (mUTIs) in primary care lacks international consensus. The main objective of this study was to describe the different guidelines for the diagnosis and management of mUTIs in primary care, to assess their methodological quality, and to describe their evidence-based strength of recommendation (SoR). METHODS An international systematic literature review of the electronic databases Medline (PubMed) and EMBASE, and gray-literature guideline-focused databases was performed in 2021. The Appraisal of Guidelines for Research and Evaluation (AGREE II) assessment tool was used by 2 independent reviewers to appraise each guideline. RESULTS From 1,678 records identified, 1,558 were screened, 134 assessed for eligibility, and 29 updated guidelines met the inclusion criteria (13 from Medline, 0 from EMBASE, and 16 from gray literature). Quality assessment revealed 14 (48%) guidelines with high-quality methodology. A grading system methodology was used in 18 (62%) guidelines. Different classifications of mUTIs are described, underlining a lack of international consensus: an anatomic classification (cystitis, prostatitis, pyelonephritis) and a symptomatic classification (approach based on the intensity and tolerance of symptoms). The duration of antibiotic treatment for febrile mUTIs has been gradually reduced over the last 20 years from 28 days to 10-14 days of fluoroquinolones (FQ), which has become the international gold standard. Guidelines from Scandinavian countries propose short courses (3-5 days) of FQ-sparing treatments: pivmecillinam, nitrofurantoin, or trimethoprim. Guidelines from French-speaking countries use a watchful waiting approach and suggest treating mUTIs with FQ, regardless of fever. CONCLUSIONS This lack of scientific evidence leads to consensus and disagreement: 14 days of FQ for febrile mUTIs is accepted despite a high risk of antimicrobial resistance, but FQ-sparing treatment and/or short treatment for afebrile mUTIs is not. The definition of afebrile UTIs/cystitis is debated and influences the type and duration of antibiotic treatment recommended.

[PMID: 36837399 PMCID: PMC9958684 DOI: 10.3390/medicina59020198] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Revised: 01/16/2023] [Accepted: 01/16/2023] [Indexed: 01/20/2023]
Abstract
Urinary tract infections (UTIs) are the most prevalent complications in kidney transplant (KTx) recipients. The most frequent finding in this group of patients is asymptomatic bacteriuria (ASB). Here, we provide an overview of the available evidence regarding ASB in KTx recipients, including its etiopathology, clinical impact and management. There is a growing body of evidence from clinical trials that screening for and treating ASB is not beneficial in most KTx recipients. However, there are insufficient data to recommend or discourage the use of a "screen-and-treat strategy" for ASB during the first 1-2 months post-transplant or in the case of an indwelling urinary catheter. Despite its frequency, ASB after KTx is still an understudied phenomenon.

A systematic scoping review of faropenem and other oral penems: treatment of Enterobacterales infections, development of resistance and cross-resistance to carbapenems. JAC Antimicrob Resist 2022; 4:dlac125. [PMID: 36570688 PMCID: PMC9777757 DOI: 10.1093/jacamr/dlac125] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Accepted: 11/16/2022] [Indexed: 12/24/2022] Open
Abstract
Background Antimicrobial resistance is an urgent global healthcare concern. Beyond carbapenems as broad-spectrum, often 'last resort' antibiotics, oral penem antibiotics currently are approved only in Japan and India, used for the treatment of indications including urinary tract infections (UTIs). Exploring oral penem use to better understand the impact of antibiotic resistance on public health would help inform the management of infectious diseases, including UTIs. Scoping Review Methodology This scoping review investigated the impact of faropenem and other oral penems on Enterobacterales infection treatment and evaluated evidence for faropenem resistance and cross-resistance to carbapenems. PubMed, Embase, J-STAGE and CiNii were searched for relevant English- or Japanese-language articles published between 1 January 1996 and 6 August 2021. Key Findings From 705 unique publications, 29 eligible articles were included (16 in vitro studies; 10 clinical trials; 2 in vitro and in vivo studies; and 1 retrospective medical chart review). Limited evidence described faropenem to treat infectious disease; only four randomized clinical trials were identified. Faropenem dosing regimens varied broadly within and between indications. One study indicated potential dependence of penem efficacy on underlying antibiotic resistance mechanisms, while several studies reported UTI persistence or recurrence after faropenem treatment. In vitro MIC data suggested some potential bacterial resistance to faropenem, while limited clinical data showed resistance emergence after faropenem treatment. Preliminary in vitro evidence suggested faropenem resistance might foster cross-resistance to carbapenems. Overall, very limited clinical evidence describes faropenem for treating infectious diseases. Preclinical and clinical research investment and dedicated community surveillance monitoring is crucial for understanding faropenem treatment patterns, resistance and potential cross-resistance to carbapenems.

Distribution of extraintestinal pathogenic Escherichia coli O-serotypes and antibiotic resistance in blood isolates collected from patients in a surveillance study in Japan. J Infect Chemother 2022; 28:1445-1451.

Abstract
INTRODUCTION Invasive extraintestinal pathogenic Escherichia coli (ExPEC) disease (IED), characterised by sepsis and bacteraemia, is a major global healthcare concern worsened by emerging multidrug resistant (MDR) strains. The development of multivalent prophylactic vaccines targeting E. coli strains of IED-associated O-serotypes could address this. A better understanding of O-serotype distribution is required for this purpose. Here, we characterised O-serotype prevalence and drug resistance among ExPEC bacteraemia isolates in Japan. METHODS E. coli blood isolates from patients aged ≥60 years with bacteraemia were obtained from a retrospective surveillance study in Japan (2015-2017). O-serotyping was performed by agglutination; for isolates non-typeable by agglutination, O-genotyping was performed. Antimicrobial susceptibility was evaluated by broth microdilution using a 21-antibiotic panel. The frequency of drug resistant (DR) isolates was evaluated by antimicrobial susceptibility testing. RESULTS Of 401 ExPEC bacteraemia isolates evaluated, the most prevalent O-serotype (≥1%) was O25 (28.7% [n = 115]), followed by O1 (14.2% [n = 57]), O2 (8.5% n = 34]), O6 (5.5% [n = 22]), O75, O18, O13, O16, O15, O4, O46/O134, O86, O8 and O83 (each <5% prevalence). These 14 O-serotypes accounted for 81.5% of isolates collected. In total, 19% (n = 77) of isolates were DR ≥ 3, of which 59.7% were O25. Fluoroquinolone-resistance among all and O25 isolates was most prevalent (35.7% and 84.3%, respectively). Almost all (98%) isolates identified as O25 were of subtype O25B. CONCLUSIONS E. coli serotype O25B showed the highest prevalence and highest multidrug resistance among ExPEC bacteraemia isolates from patients ≥60 years in Japan. Our data may inform development of multivalent glycoconjugate vaccines to prevent IED.

Bacteriospermia and Male Infertility: Role of Oxidative Stress. ADVANCES IN EXPERIMENTAL MEDICINE AND BIOLOGY 2022; 1358:141-163.

Abstract
Male infertility is one of the major challenging and prevalent diseases having diverse etiologies of which bacteriospermia play a significant role. It has been estimated that approximately 15% of all infertility cases are due to infections caused by uropathogens and in most of the cases bacteria are involved in infection and inflammation leading to the development of bacteriospermia. In response to bacterial load, excess infiltration of leukocytes in the urogenital tract occurs and concomitantly generates oxidative stress (OS). Bacteria may induce infertility either by directly interacting with sperm or by generating reactive oxygen species (ROS) and impair sperm parameters such as motility, volume, capacitation, hyperactivation. They may also induce apoptosis leading to sperm death. Acute bacteriospermia is related with another clinical condition called leukocytospermia and both compromise male fertility potential by OS-mediated damage to sperm leading to male infertility. However, bacteriospermia as a clinical condition as well as the mechanism of action remains poorly understood, necessitating further research in order to understand the role of individual bacterial species and their impact in male infertility.

A global perspective on improving patient care in uncomplicated urinary tract infection: Expert consensus and practical guidance. J Glob Antimicrob Resist 2021; 28:18-29.

Abstract
BACKGROUND Uncomplicated urinary tract infections (uUTIs) are a common problem in women. Management is mainly based on empirical prescribing, but there are concerns about overtreatment and antimicrobial resistance (AMR), especially in patients with recurrent uUTIs. METHODS A multidisciplinary panel of experts met to discuss diagnosis, treatment, prevention, guidelines, AMR, clinical trial design, and the impact of COVID-19 on clinical practice. RESULTS Symptoms remain the cornerstone of uUTI diagnosis, and urine culture is necessary only when empirical treatment fails, or rapid recurrence of symptoms or AMR is suspected. Specific antimicrobials are first-line therapy (typically nitrofurantoin, fosfomycin, trimethoprim-sulfamethoxazole, and pivmecillinam; dependent on availability and local resistance data). Fluoroquinolones are not first-line options for uUTIs due primarily to safety concerns, but also rising resistance rates. High-quality data to support most non-antimicrobial approaches are lacking. Local AMR data specific to community-acquired uUTIs are needed, but representative information is difficult to obtain; instead, identification of risk factors for AMR can provide a basis to guide empirical antimicrobial prescribing. The COVID-19 pandemic has impacted management of uUTIs in some countries and may have long-lasting implications for future models of care. CONCLUSIONS The management of uUTIs in women can be improved without increasing complexity, including simplified diagnosis, and empirical antimicrobial prescribing based on patient characteristics, including review of recent antimicrobial use and past pathogen resistance profiles, drug availability, and guidelines. Current data for non-antimicrobial approaches are limited. The influence of COVID-19 on telehealth could provide an opportunity to enhance patient care in the long term.

Abstract
Purpose of review Our goal was to summarize recent evidence regarding recurrent urinary tract infections and asymptomatic bacteriuria in different adult populations. Recent findings Several research groups are focused on the description of resident bacterial flora in the bladder and urinary dysbiosis in the microbiome era. Even the definitions might change in light of these discoveries. However, the role of urinary microbiome and bacterial interference has still to be determined. Summary Systematic treatment of asymptomatic bacteriuria is not recommended and even classic indications such as asymptomatic bacteriuria in pregnant women are controversial. In fact, its treatment is associated with a higher probability of symptomatic UTI and a higher prevalence of antibiotic-resistant bacteria. Improving the diagnosis of asymptomatic bacteriuria and optimizing the management of recurrent urinary tract infections, especially through non-antibiotics measures, are needed in order to minimise antimicrobial resistance.

Effect of Antimicrobial Stewardship on Oral Quinolone Use and Resistance Patterns over 8 Years (2013-2020). Antibiotics (Basel) 2021; 10:antibiotics10111426. [PMID: 34827364 PMCID: PMC8615025 DOI: 10.3390/antibiotics10111426] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Revised: 10/28/2021] [Accepted: 11/18/2021] [Indexed: 12/24/2022] Open
Abstract
Since 2014, several global and national guidelines have been introduced to address the problem of antimicrobial resistance. We conducted a campaign in a tertiary hospital to promote appropriate quinolone use through educational lectures in 2018. The aim of this retrospective study was to evaluate the changes in the following: prescription characteristics, trend of oral quinolone use, and antibiotic susceptibility of bacteria from 2013 to 2020. Antimicrobial use was assessed as days of therapy per 1000 patient-days. We found a significant reduction in unnecessary antibiotic prescriptions between December 2013 and December 2020. Significant negative trends were detected in the use of quinolones over 8 years (outpatients, coefficient = −0.15655, p < 0.001; inpatients, coefficient = −0.004825, p = 0.0016). In particular, the monthly mean use of quinolones among outpatients significantly decreased by 11% from 2013 to 2014 (p < 0.05) and reduced further by 31% from 2017 to 2020 (p < 0.001). A significant positive trend was observed in the susceptibility of Pseudomonas aeruginosa to levofloxacin (p < 0.001). These results demonstrate that the use of oral quinolones was further reduced following educational intervention and the bacterial susceptibility improved with optimal quinolone usage compared to that in 2013.

Abstract
The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2020 (J-SSCG 2020), a Japanese-specific set of clinical practice guidelines for sepsis and septic shock created as revised from J-SSCG 2016 jointly by the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine, was first released in September 2020 and published in February 2021. An English-language version of these guidelines was created based on the contents of the original Japanese-language version. The purpose of this guideline is to assist medical staff in making appropriate decisions to improve the prognosis of patients undergoing treatment for sepsis and septic shock. We aimed to provide high-quality guidelines that are easy to use and understand for specialists, general clinicians, and multidisciplinary medical professionals. J-SSCG 2016 took up new subjects that were not present in SSCG 2016 (e.g., ICU-acquired weakness [ICU-AW], post-intensive care syndrome [PICS], and body temperature management). The J-SSCG 2020 covered a total of 22 areas with four additional new areas (patient- and family-centered care, sepsis treatment system, neuro-intensive treatment, and stress ulcers). A total of 118 important clinical issues (clinical questions, CQs) were extracted regardless of the presence or absence of evidence. These CQs also include those that have been given particular focus within Japan. This is a large-scale guideline covering multiple fields; thus, in addition to the 25 committee members, we had the participation and support of a total of 226 members who are professionals (physicians, nurses, physiotherapists, clinical engineers, and pharmacists) and medical workers with a history of sepsis or critical illness. The GRADE method was adopted for making recommendations, and the modified Delphi method was used to determine recommendations by voting from all committee members.As a result, 79 GRADE-based recommendations, 5 Good Practice Statements (GPS), 18 expert consensuses, 27 answers to background questions (BQs), and summaries of definitions and diagnosis of sepsis were created as responses to 118 CQs. We also incorporated visual information for each CQ according to the time course of treatment, and we will also distribute this as an app. The J-SSCG 2020 is expected to be widely used as a useful bedside guideline in the field of sepsis treatment both in Japan and overseas involving multiple disciplines.

Abstract
Patients with diabetes mellitus (DM) sometimes exhibited impaired immune function and aggravated infectious diseases. Urinary tract infection (UTI) is one of the major complications of DM. A systematic literature search was performed in PubMed and Cochrane Library using the following keywords: diabetes mellitus, urinary tract infection, asymptomatic bacteriuria, emphysematous pyelonephritis, emphysematous cystitis, renal papillary necrosis, and sodium-glucose co-transporter 2 (SGLT2) inhibitors. The treatment of UTI in DM patients is not different from that in non-DM patients, and asymptomatic bacteriuria should not be screened or treated. Emphysematous pyelonephritis is a life-threatening renal infection with gas in the renal parenchyma or perirenal space, and 95% of affected patients had DM. Abdominal computed tomography is useful for diagnosis and determining treatment strategies. Medical management and percutaneous drainage are standard initial treatment, and subsequent nephrectomy for non-responders is considered. Nephrectomy, as an initial treatment, should be limited to a selected group of patients with severe conditions. In contrast, antibiotics, glycemic control, and bladder drainage are adequate treatment for most cases of emphysematous cystitis. SGLT2 inhibitors significantly increased the incidence of genital tract infection, but not that of UTI, pyelonephritis, or urosepsis. Here, we present cumulative evidence about etiology and management for complicated UTI with DM, but there was little information about racial differences and further evidence focusing on Asian population will be needed.

Positive urine culture under indwelling urethral catheterization is a risk factor for febrile complications after holmium laser enucleation of the prostate (HoLEP). Low Urin Tract Symptoms 2021; 13:377-382. [PMID: 33847442 DOI: 10.1111/luts.12380] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2021] [Revised: 03/16/2021] [Accepted: 03/22/2021] [Indexed: 12/01/2022]
Abstract
OBJECTIVES To investigate the incidence of and risk factors for febrile complications (FCs) in patients undergoing holmium laser enucleation of the prostate (HoLEP). METHODS This retrospective study enrolled 847 consecutive patients who underwent HoLEP in our hospital from June 2006 to December 2018. FCs were defined as a body temperature ≥38.0°C within 30 days after surgery. The incidence of FCs was determined and possible risk factors assessed using multivariate logistic regression analysis. RESULTS Overall, 87 (10.3%) patients presented with FCs, and 6 (0.7%) had urosepsis, with no fatal complications. Multivariate logistic regression analysis revealed that patients with preoperative positive urine culture and urethral catheterization had an increased risk of FCs compared with those with a negative culture who did not need catheterization (odds ratio [OR] 2.587, 95% confidence interval [CI] 1.307-5.121). A negative urine culture with catheterization and a positive culture without catheterization were not associated with the development of FCs (OR 0.320, 95% CI 0.040-2.553 and OR 1.370, 95% CI 0.662-2.365, respectively). Other significant risk factors included preoperative serum albumin levels (OR 0.382, 95% CI 0.173-0.846) and immediate postoperative body temperature (OR 2.559, 95% CI 1.549-4.230). CONCLUSIONS FCs are relatively common among patients after HoLEP despite preoperative prophylactic antibiotic administration. Surgeons may need to consider performing screening of urine cultures prior to HoLEP, especially in patients with urethral catheterization, even if asymptomatic. If the culture is positive, prophylactic antibiotics should be tailored according to bacterial susceptibility.

Prostatic Pharmacokinetic/Pharmacodynamic Evaluation of Ampicillin-Sulbactam for Bacterial Prostatitis and Preoperative Prophylaxis. J Clin Pharmacol 2021; 61:820-831. [PMID: 33314138 DOI: 10.1002/jcph.1800] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2020] [Accepted: 12/08/2020] [Indexed: 12/23/2022]
Abstract
This study aims to define the penetration of ampicillin and sulbactam into prostate tissue, develop a prostatic pharmacokinetic model of each drug, and assess the appropriateness of ampicillin-sulbactam regimens for the treatment of prostatitis and the prophylaxis of postoperative infection, based on a pharmacokinetic and pharmacodynamic simulation. Subjects were prostatic hyperplasia patients prophylactically receiving a 0.5-hour infusion of 1.5 g (1:0.5 g) or 3 g (2:1 g) ampicillin-sulbactam before transurethral resection of the prostate. Ampicillin and sulbactam concentrations in plasma and prostate tissue were measured. The prostate tissue/plasma ratios of both ampicillin and sulbactam were approximately 0.37 (area under the drug concentration-time curve), and penetration was similar. The prostatic population pharmacokinetic model, which included a covariate analysis, adequately predicted prostate tissue concentrations in our patient population. For therapeutic use, aiming for a bactericidal target of 50% of time above minimum inhibitory concentration (T > MIC) in prostate tissue, 3 g ampicillin-sulbactam 4 times daily achieved ≥90% expected probability against only Enterococcus faecalis in typical patients with a creatinine clearance (CLcr ) of 30 mL/min. For prophylactic use, aiming for a bacteriostatic target of 30% T > MIC, 3 g ampicillin-sulbactam 4 times daily achieved ≥90% expected probability of attaining the bacteriostatic target against E. faecalis and Proteus species when CLcr was 30 mL/min. Based on prostatic simulations, the present study provides helpful recommendations for the treatment of bacterial prostatitis and preoperative prophylaxis in prostatectomy.

Abstract
The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2020 (J-SSCG 2020), a Japanese-specific set of clinical practice guidelines for sepsis and septic shock created as revised from J-SSCG 2016 jointly by the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine, was first released in September 2020 and published in February 2021. An English-language version of these guidelines was created based on the contents of the original Japanese-language version. The purpose of this guideline is to assist medical staff in making appropriate decisions to improve the prognosis of patients undergoing treatment for sepsis and septic shock. We aimed to provide high-quality guidelines that are easy to use and understand for specialists, general clinicians, and multidisciplinary medical professionals. J-SSCG 2016 took up new subjects that were not present in SSCG 2016 (e.g., ICU-acquired weakness [ICU-AW], post-intensive care syndrome [PICS], and body temperature management). The J-SSCG 2020 covered a total of 22 areas with four additional new areas (patient- and family-centered care, sepsis treatment system, neuro-intensive treatment, and stress ulcers). A total of 118 important clinical issues (clinical questions, CQs) were extracted regardless of the presence or absence of evidence. These CQs also include those that have been given particular focus within Japan. This is a large-scale guideline covering multiple fields; thus, in addition to the 25 committee members, we had the participation and support of a total of 226 members who are professionals (physicians, nurses, physiotherapists, clinical engineers, and pharmacists) and medical workers with a history of sepsis or critical illness. The GRADE method was adopted for making recommendations, and the modified Delphi method was used to determine recommendations by voting from all committee members. As a result, 79 GRADE-based recommendations, 5 Good Practice Statements (GPS), 18 expert consensuses, 27 answers to background questions (BQs), and summaries of definitions and diagnosis of sepsis were created as responses to 118 CQs. We also incorporated visual information for each CQ according to the time course of treatment, and we will also distribute this as an app. The J-SSCG 2020 is expected to be widely used as a useful bedside guideline in the field of sepsis treatment both in Japan and overseas involving multiple disciplines.

Efficacy of fosfomycin in the prevention of postoperative infection following transurethral resection of bladder tumor during periods of limited cefazolin, cefotiam, and cefmetazole supply. J Infect Chemother 2020; 27:625-631. [PMID: 33309628 DOI: 10.1016/j.jiac.2020.11.025] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2020] [Revised: 10/29/2020] [Accepted: 11/27/2020] [Indexed: 11/19/2022]
Abstract
INTRODUCTION In March 2019, cefazolin availability was limited owing to the contamination of the drug substance. In addition, there was a difficulty in supplying drugs alternative to cefazolin, such as cefotiam and cefmetazole. In our Department of Nephro-urology, we used fosfomycin-based drugs to substitute cefazolin as perioperative preventive antibacterial drugs. In this study, we aimed to evaluate the usage status of perioperative prophylactic antibacterial drugs before and after the period of limited cefazolin supply and to investigate the efficacy and safety of fosfomycin sodium in preventing infections following transurethral resection of bladder tumor. METHODS We enrolled 346 patients who underwent transurethral resection of bladder tumor in our department from April 2018 to August 2020. The patients received the following perioperative antibacterial agents: cefotiam (n = 146), fosfomycin (n = 166), and other antibacterial agents (n = 34). There was no significant difference in the median age or surgery time. RESULTS The median length of hospital stay was 6, 5, and 5 days in the cefotiam, fosfomycin, and other antibacterial groups, respectively, with significant difference. The median maximum postoperative temperature was 37.1 °C in all groups, with no significant difference. There were no differences in C-reactive protein, aspartate aminotransferase, and alanine aminotransferase levels determined by postoperative blood tests; preoperative and postoperative urinary white blood cell counts; preoperative urine bacterial counts; and surgery-related infection requiring additional antibiotic treatments among the groups. CONCLUSIONS The use of fosfomycin-based agents helped overcome the limited supply of cefazolin without worsening clinical outcomes.

Abstract
INTRODUCTION Urinary tract infections (UTIs) are extremely common. Millions of people, particularly healthy women, are affected worldwide every year. One-in-two women will have a recurrence within 12-months of an initial UTI. Inadequate treatment risks worsening infection leading to acute pyelonephritis, bacteremia and sepsis. In an era of increasing antimicrobial resistance, it is critical to provide optimized antimicrobial treatment. AREAS COVERED Literature was searched using PubMed and Google Scholar (up to 06/2020), examining the etiology, diagnosis and oral antimicrobial therapy for uncomplicated UTIs, with emphasis on urinary antimicrobial pharmacokinetics (PK) and the application of dynamic in vitro models for the pharmacodynamic (PD) profiling of pathogen response. EXPERT OPINION The majority of antimicrobial agents included in international guidelines were developed decades ago without well-described dose-response relationships. Microbiology laboratories still apply standard diagnostic methodology that has essentially remained unchanged for decades. Furthermore, it is uncertain how relevant standard in vitro susceptibility is for predicting antimicrobial efficacy in urine. In order to optimize UTI treatments, clinicians must exploit the urine-specific PK of antimicrobial agents. Dynamic in vitro models are valuable tools to examine the PK/PD and urodynamic variables associated with UTIs, while informing uropathogen susceptibility reporting, optimized dosing schedules, clinical trials and treatment guidelines.

Abstract
INTRODUCTION Nitrofurantoin is a well-established antibiotic, and is an important first-line oral treatment for uncomplicated urinary tract infections. However, little information is available with respect to its antibacterial activity in Japan, in vivo efficacy, or the in vivo biological cost of resistant strains. METHODS We compared the susceptibility of six representative antibacterial agents-nitrofurantoin, sulfamethoxazole/trimethoprim, fosfomycin, mecillinam, ciprofloxacin, and cefdinir-against E. coli clinically isolated in Japan during 2017. We evaluated the in vivo efficacy of nitrofurantoin using a model of mouse urinary tract infection caused by ciprofloxacin resistant E. coli. We obtained nitrofurantoin resistant isolates through tests generating spontaneous mutations, and assessed the in vivo fitness of nitrofurantoin resistant isolates. RESULTS The MIC90 of nitrofurantoin was 16 μg/mL, and was the lowest among the drugs tested. It was found that, in the mouse urinary tract infection model, 30 mg/kg and 100 mg/kg of nitrofurantoin reduced the count of viable bacterial cells in the kidney, while 100 mg/kg of ciprofloxacin did not. All spontaneous bacterial mutants resistant to nitrofurantoin had deletions in the nfsA gene, and we found that the resistant strain had lower growth in the mouse urinary tract infection model than in the parent strain. CONCLUSIONS We demonstrated promising in vitro and in vivo activity of nitrofurantoin against E. coli clinical isolates in Japan, and lower in vivo fitness of the resistant strain of nitrofurantoin.

Abstract
INTRODUCTION A large number of antibiotics are used for the treatment of uncomplicated cystitis owing to its high morbidity. As the administration of antibiotics for uncomplicated cystitis may be considered an example of inappropriate use, outpatient antimicrobial stewardship for this condition is important. We evaluated the current pharmacoepidemiology trends for the treatment of uncomplicated cystitis in Japan to predict stewardship strategies. METHODS This descriptive observational study analyzed data from an anonymized claims database of employees and their family members covered by the employer's health insurance. We identified female outpatients diagnosed with acute cystitis (ICD-10 code N300) aged ≥15 years and extracted oral antibiotic prescription records between 2013 and 2016. We excluded prescriptions for >7 days. RESULTS The most prescribed antibiotic category was fluoroquinolones (52.67%), followed by cephalosporins and penems (40.63%). Third-generation cephalosporins accounted for 90.91% of cephalosporin and penem prescriptions. The most common duration of antibiotic prescription was 5 days, except for first-generation cephalosporins, penem (7 days) and sulfamethoxazole and trimethoprim (3 days). CONCLUSION Fluoroquinolones and third-generation cephalosporins were prescribed to most uncomplicated cystitis cases in Japan. Although the lack of alternatives to quinolones and beta-lactams in Japan is an obstacle for antimicrobial stewardship for uncomplicated cystitis, promoting accurate diagnoses and establishing alternatives available in the Japanese market are important. Shortening the treatment duration is also an important strategy. Further research is needed on local antimicrobial resistance patterns to determine a fixed treatment strategy for uncomplicated cystitis.

Abstract
Antibiotic resistance is a threat to public health, and uncomplicated urinary tract infections (uUTIs) are an example of this concern. This systematic review (International Prospective Register of Systematic Reviews [PROSPERO] ID: CRD42020156674) is the first to determine the prevalence of Escherichia coli resistance to fluoroquinolones in women with community-acquired uUTI. PubMed and Embase searches were conducted; 38 studies fulfilled eligibility criteria and were included in the systematic review. Within Europe, ciprofloxacin resistance in E. coli isolates varied between countries and increased in some from 2006 to 2008 and 2014 to 2016, specifically in the United Kingdom (0.5% to 15.3%), Germany (8.7% to 15.1%), and Spain (22.9% to 30.8%), although methodologies and settings were often not comparable. In Asia, there was a substantial increase in ciprofloxacin resistance during 2008 to 2014 from 25% to more than 40%. In North America, resistance to ciprofloxacin also increased between 2008 and 2017, from 4% to 12%. Data exploring different age groups did not show a consistent relationship with resistance, whereas two studies found that fluoroquinolone resistance was higher in postmenopausal women than premenopausal women. One study indicated a link between fluoroquinolone resistance and uUTI recurrence. These findings may have implications for the empirical treatment of uUTI with fluoroquinolones globally, but more data are needed to fully understand regional situations and impact patient management.

Abstract
INTRODUCTION Eradication of asymptomatic bacteriuria (ASB) before urological procedures is important to reduce the risk for infectious complications after surgery. However, the appropriate regimen for antimicrobial treatment has not been fully determined. We experienced continuous (over 10 months) isolation of extended spectrum β-lactamase (ESBL)-producing fluoroquinolone-resistant Escherichia coli from urine of an asymptomatic patient. The four isolates obtained (SMESC1 to 4) were international high-risk clones of O25b:H4-ST131-H30R, and originated from one strain, as revealed by the whole genome sequences. Although the patient received meropenem (MEPM) and fosfomycin (FOM), to which the strains were susceptible before the urological procedures, they could not be eradicated. METHODS To explore the reason for the continuous isolation even after MEPM and FOM administration, antimicrobial killing of adherent and/or intracellular bacterial communities (IBC) formed by coculture of the E. coli cells and T24 bladder epithelial cells were examined. RESULTS FOM and levofloxacin did not decrease viable E. coli cells compared with gentamicin. MEPM partly decreased them, and sitafloxacin (STFX) decreased them most potently. These observations indicate that E. coli can survive in the urinary tract under antimicrobial administration, and some antimicrobials such as FOM and MEPM cannot eradicate E. coli in uroepithelial cells. Adhesion on urinary epithelial cells and/or IBC formation might result in continuous isolation from the urinary tract and recurrence of ASB and urinary tract infections. CONCLUSIONS The present study suggests that STFX is a promising optional agent for the eradication of ESBL-producing fluoroquinolone-resistant E. coli in the urinary tract before urological procedures.

Abstract
A specific antibiogram is necessary for the empiric antibiotic treatment of community-acquired urinary tract infections (UTI) because of the global spread of antimicrobial resistance. This study aimed to develop an antibiogram specific for community-acquired UTI and assess the risk factors associated with community-acquired UTI caused by antimicrobial-resistant organisms. This cross-sectional observational retrospective study included patients with community-acquired UTI caused by Gram-negative rods (GNR) who were admitted to the emergency department at a tertiary care hospital in Ibaraki, Japan, in 2017–2018. A total of 172 patients were enrolled (including 38 nursing home residents). Of the 181 GNR strains considered as causative agents, 135 (75%) were Escherichia coli, and 40 (22%) exhibited third-generation cephalosporin resistance. Extended-spectrum β-lactamase (ESBL)-producing E. coli accounted for 25/40 (63%) of resistant GNR. Overall susceptibility rate of Enterobacterales was 92%, 81%, 100%, 75%, and 89% for cefmetazole, ceftriaxone, meropenem, levofloxacin, and trimethoprim–sulfamethoxazole, respectively. Residence in a nursing home (odds ratio (OR), 2.83; 95% confidence interval (CI), 1.18–6.79) and recent antibiotic use (OR, 4.52; 95% CI, 1.02–19.97) were independent risk factors for UTI with resistant GNR. ESBL-producing E. coli was revealed to have a strong impact on antimicrobial resistance pattern. Therefore, an antibiotic strategy based on a disease-specific antibiogram is required.

Abstract
Background Wide-spectrum antibiotics have been favored to treat acute uncomplicated cystitis (AUC) for a long time, leading to the emergence of multi-drug resistant bacteria. We hypothesize that narrow-spectrum antibiotics might mitigate the issue and aim to investigate the clinical efficacy of cefaclor in patients with AUC. Methods We retrospectively reviewed the clinical data of female outpatients with AUC treated with cefaclor and evaluated the safety and clinical efficacy. Clinical cure was defined as the elimination of clinical symptom under 4 white blood cells (WBCs) per high power field on microscopy. Results Overall, 223 women with AUC were enrolled. Escherichia coli was the dominant pathogen (n = 160; 68.6%), followed by Klebsiella species and E. coli-extended spectrum β-lactamase (ESBL) (n = 19; 8.1% and n = 18; 7.7%). Overall success rate was 94.0% (n = 219) and susceptibility rate of cefazolin was 84.1%, which was close to that of levofloxacin (82.9%). Ampicillin showed the lowest rate of 63.7% with a significantly greater resistance rate of 35.3% among all antibiotics (P < 0.001). In the subgroup analysis, the success rate in patients with resistance to levofloxacin or cefazolin was 100% (n = 24) or 93.3% (n = 14). The rate in patients with resistance to both antibiotics was 60.0% (n = 9), and the pathogens in the other 40.0% (n = 6) of patients with treatment failure were E. coli-ESBL. Conclusion Cefaclor showed excellent efficacy in AUC patients, even in those with in vitro resistance to cefazolin or levofloxacin. Cefaclor may be considered as a first-line option in patients with AUC and a second-line option for those with levofloxacin treatment failure.

Clinical pharmacokinetics of flomoxef in prostate tissue and dosing considerations for prostatitis based on site-specific pharmacodynamic target attainment. J Infect Chemother 2019; 26:236-241. [PMID: 31822449 DOI: 10.1016/j.jiac.2019.08.019] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2019] [Revised: 08/22/2019] [Accepted: 08/29/2019] [Indexed: 11/18/2022]
Abstract
Flomoxef is used to treat bacterial prostatitis; however, its prostatic pharmacokinetics have not been fully clarified. Flomoxef (500 or 1000 mg) was administered to patients with benign prostatic hypertrophy (n = 54). After a 0.5-h infusion, venous blood samples were drawn at time points of 0.5-5 h, and prostate tissue samples were collected at time points of 0.5-1.5 h during transurethral resection of the prostate. The drug concentrations in plasma and prostate tissue were analyzed pharmacokinetically and used for a stochastic simulation to predict the probability of attaining pharmacodynamic target in prostate tissue. Showing dose linearity in the prostatic pharmacokinetics, flomoxef rapidly penetrated into prostate tissue, with a prostate/plasma ratio of 0.48-0.50 (maximum drug concentration) and 0.42-0.55 (area under the drug concentration-time curve). Against the tested populations of Escherichia coli, Klebsiella and Proteus species isolates, 0.5-h infusion of 1000 mg three times daily achieved a ≥90% expected probability of attaining the bactericidal target (70% of the time above the minimum inhibitory concentration [MIC]) in prostate tissue. The site-specific pharmacodynamic-based breakpoint (the highest MIC at which the target-attainment probability in prostate tissue was >90%) values were 0.25 mg/L (MIC for 90th percentile of E. coli and Klebsiella species) for 500 mg four times daily and 0.5 mg/L (MIC90 of Proteus species) for 1000 mg four times daily. These results help to fully characterize the prostatic pharmacokinetics of flomoxef, while also helping to rationalize and optimize the dosing regimens for prostatitis based on site-specific pharmacodynamic target attainment.

Higher incidence of acute kidney injury in patients treated with piperacillin/tazobactam than in patients treated with cefepime: a single-center retrospective cohort study. J Pharm Health Care Sci 2019; 5:13. [PMID: 31210955 PMCID: PMC6560868 DOI: 10.1186/s40780-019-0142-6] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2019] [Accepted: 05/21/2019] [Indexed: 12/21/2022] Open
Abstract
Background Piperacillin/tazobactam (PIPC/TAZ) and cefepime (CFPM) are commonly used for the treatment of nosocomial and healthcare-associated infections. Recent reports have suggested that the incidence of acute kidney injury (AKI) in patients treated with a combination of vancomycin (VCM) and PIPC/TAZ is higher than that in patients treated with CFPM. However, there have been few reports on a comparison of the incidences of AKI in patients treated with PIPC/TAZ monotherapy and patients treated with CFPM. In this study, we investigated whether the incidence of AKI in patients treated with PIPC/TAZ is higher than that in patients treated with CFPM. Methods This study was a single-center retrospective observational study. Patients who died during the therapeutic period, patients younger than 18 years of age, and patients undergoing hemodialysis were excluded. Primary outcomes were the incidence of AKI and the AKIN stages defined by the Acute Kidney Injury Network. Secondary outcomes were discontinuation and/or change of antibiotics and initiation of dialysis due to AKI. We also investigated the time to onset and the risk factors of AKI in this population. Results There were 163 patients in the PIPC/TAZ group and 103 patients in the CFPM group. The incidence of AKI in patients treated with PIPC/TAZ (8.6%) was significantly higher than that in patients treated with CFPM (0.9%) (odds ratio (OR), 9.53; 95% confidence interval (CI), 1.41–408; p= 0.011). AKI severity was mostly stage 1 in both groups. There was no discontinuation and/or changes of antibiotics and there was no initiation of dialysis in either group. The onset of AKI in the PIPC/TAZ group (median period of 4 days) was earlier than that in the CFPM group. PIPC/TAZ was determined to be an independent risk factor of AKI in multivariate analysis (adjusted OR, 9.56; 95% CI, 1.21–75.3; p = 0.032). Conclusions This study showed that the incidence of AKI in patients who received PIPC/TAZ was higher than that in patients who received CFPM. Furthermore, the onset of AKI was earlier in patients who received PIPC/TAZ than in patients who received CFPM. PIPC/TAZ was an independent risk factor of AKI in this study population.

Abstract
INTRODUCTION To investigate the risk factors for febrile genito-urinary tract infection (GUTI) in spinal cord injury-associated neurogenic lower urinary tract dysfunction (NLUTD) patients who perform routine clean intermittent catheterization (CIC) evaluated by urodynamic study (UDS) and cystography. PATIENTS AND METHODS Over a 3-year period, we retrospectively assessed risk factors for febrile UTI in 141 spinal cord injury patients diagnosed as NLUTD and performing routine CIC, regarding gender, UDS findings such as bladder compliance, maximum cystometric capacity, and cystography. RESULTS A total of 41 patients had febrile GUTI in the follow-up period as along with 32 cases of pyelonephritis, 10 cases of epididymitis, and 1 case of prostatitis, including patients with multiple infectious diseases. The causative bacteria were Escherichia coli (14 cases) followed by Pseudomonas aeruginosa (n = 5), Klebsiella pneumoniae (n = 4), and Klebsiella oxytoca (n = 4). Antibiotic-resistant E. coli were seen, with 36.4% instances of extended-spectrum beta-lactamase production in whole of E. coli. Male gender (p = 0.018), ASIA Impairment Scale (AIS) C or more severe (p = 0.031), the number of CIC (p = 0.034), use of quinolones (p < 0.001) and severe bladder deformity (DG 2 or more, p = 0.004) were significantly associated with febrile GUTI occurrence. CONCLUSIONS Our data demonstrated that male gender, severe bladder deformity (DG 2 or more), AIS C or more, the number of CIC, and use of quinolones were significantly associated with febrile GUTI occurrence in NLUTD patients employing routine CIC. Further prospective studies are necessary to define the full spectrum of possible risk factors for febrile GUTI in these patients.

Abstract
Urinary tract infection (UTI) in children requires early diagnosis and treatment to prevent repeated UTI and renal scarring. This study aimed to evaluate the usefulness of the point-of-care Gram stain by physicians for suspected UTI in children at Okinawa Chubu Hospital as a rapid diagnostic test.A single-center, retrospective study was undertaken between January 2011 and December 2015. Patients aged 36 months or younger who were reviewed had suspected UTI in the emergency room or outpatient clinic. Urine culture, urinalysis, and point-of-care Gram stain were performed on a single specimen. Patients with structural or functional urological defects requiring routine catheterization were excluded. We compared the diagnostic performance among the rapid diagnostic tests (i.e., pyuria, point-of-care Gram stain, or both). Kappa statistics were used to evaluate the agreement between the results of point-of-care Gram stain and morphotypes of urine culture with the 95% CI (bias corrected bootstrap interval). We also analyzed which antibiotics were more susceptible to the bacteria of urine culture results, selected by the results of point-of-care Gram stain or empirical treatment based on the Japanese guidelines by McNemar test.Of 1594 patients reviewed in the study, 1546 were eligible according to our inclusion criteria. Using urine culture as the gold standard for UTI, the sensitivity and specificity of pyuria were 73.2% and 95.1%, whereas those of the point-of-care Gram stain were 81.4% and 98.2%, respectively. The concordance rate between the morphotypes of bacteria detected by point-of-care Gram stain and those of urine culture was 0.784 (kappa coefficient) (95% CI 0.736-0.831). Furthermore, the proportion of "susceptible" in the minimum inhibitory concentration of pathogen-targeted treatment based on the point-of-care Gram stain was higher than that of empirical therapy (exact McNemar significance probability: .0001).Our analysis suggests that the point-of-care Gram stain is a useful rapid diagnostic tool for suspected UTI in young children. Pathogen-targeted treatment based on the point-of-care Gram stain would lead to better antibiotic selection compared with empirical therapy.

Abstract
The Japanese Surveillance Committee conducted a second nationwide surveillance of antimicrobial susceptibility patterns of uropathogens responsible for acute uncomplicated cystitis (AUC) in premenopausal patients aged 16-40 years old at 31 hospitals throughout Japan from March 2015 to February 2016. In this study, the susceptibility of causative bacteria (Escherichia coli, Klebsiella pneumoniae, Staphylococcus saprophyticus) for various antimicrobial agents was investigated by isolation and culturing of organisms obtained from urine samples. In total, 324 strains were isolated from 361 patients, including E. coli (n = 220, 67.9%), S. saprophyticus (n = 36, 11.1%), and K. pneumoniae (n = 7, 2.2%). The minimum inhibitory concentrations (MICs) of 20 antibacterial agents for these strains were determined according to the Clinical and Laboratory Standards Institute (CLSI) manual. At least 93% of the E. coli isolates showed susceptibility to fluoroquinolones and cephalosporins, whereas 100% of the S. saprophyticus isolates showed susceptibility to fluoroquinolones and aminoglycosides. The proportions of fluoroquinolone-resistant and extended-spectrum β-lactamase (ESBL)-producing E. coli strains were 6.4% (13/220) and 4.1% (9/220), respectively. The antimicrobial susceptibility of K. pneumoniae was retained during the surveillance period, while no multidrug-resistant strains were identified. In summary, antimicrobial susceptibility results of our second nationwide surveillance did not differ significantly from those of the first surveillance. Especially the numbers of fluoroquinolone-resistant and ESBL-producing E. coli strains were not increased in premenopausal patients with AUC in Japan.

Abstract
PURPOSE This study assessed risk factors for septic shock in patients with obstructive acute pyelonephritis (APN) associated with upper urinary tract calculi in a multi-center retrospective study. METHODS We studied 143 patients admitted to 4 hospitals in Japan with obstructive APN associated with upper urinary tract calculi. Data on gender, age, hypertension, diabetes, neurological disease or malignant disease, laboratory data (white blood cell (WBC) and C-reactive protein (CRP)), drainage, and bacterial strains including Escherichia coli in the non-septic and septic groups were collected. Risk factors for septic shock were analyzed by univariate and multivariate statistical analyses. RESULTS There were a total of 107 non-septic cases (74.8%) and 36 septic cases (25.2%). The commonest strains of urinary tract infection-causative bacteria were E. coli in the non-septic group (23 cases, 21.5%) and septic group (13 cases, 36.1%) (p > 0.05). Emergency drainage was administered in 74.8% of the non-septic group and 97.2% of the septic group (p > 0.05). Meropenem was most often used as the initial treatment in the non-septic group (20 cases, 18.7%) and septic group (22 cases, 61.1%) (p < 0.0001). Risk factors for septic shock in multivariate analyses were diabetic mellitus (odds ratio (OR) = 3.591, p = 0.0098) and CRP ≥ 10 (OR = 1.057, p = 0.0119) as significant independent factors in this multicenter study. CONCLUSIONS APN is a common infectious disease, especially in the cases with urinary tract obstruction where patients easily acquire bacteremia or sepsis. Stone-associated obstructed APN can cause fatal septic shock in cases with diabetes and CRP ≥ 10. Further prospective studies will be undertaken to draw definitive conclusions.
