RESUMO
AIMS: Although therapeutic drug monitoring (TDM) of voriconazole is performed in outpatients to prevent treatment failure and toxicity, whether TDM should be performed in all or only selected patients remains controversial. This study evaluated the association between voriconazole trough concentrations and clinical events. METHODS: We investigated the aggravation of clinical symptoms, incidence of hepatotoxicity and visual disturbances, change in co-medications and interaction between voriconazole and co-medications in outpatients receiving voriconazole between 2017 and 2021 in three facilities. Abnormal trough concentrations were defined as <1.0 mg/L (low group) and >4.0 mg/L (high group). RESULTS: A total of 141 outpatients (578 concentration measurements) met the inclusion criteria (treatment, 37 patients, 131 values; prophylaxis, 104 patients, 447 values). The percentages of patients with abnormal concentrations were 29.0% and 31.5% in the treatment and prophylaxis groups, respectively. Abnormal concentrations showed 50% of the concentrations at the first measurement in both therapies. Aggravation of clinical symptoms was most frequently observed in the low treatment group (18.2%). Adverse events were most common in the high group for both therapies (treatment, hepatotoxicity 6.3%, visual disturbance 18.8%; prophylaxis, hepatotoxicity 27.9%). No differences were found in changes to co-medications and drug interactions. In the prophylaxis group, prescription duration in the presence of clinical events tended to be longer than in their absence (47.4 ± 23.4 days vs 39.7 ± 21.9 days, P = .1132). CONCLUSIONS: We developed an algorithm based on clinical events for appropriate implementation of TDM in outpatients. However, future interventions based on this algorithm should be validated.

INTRODUCTION: Baloxavir marboxil (BXM), a newly developed cap-dependent endonuclease inhibitor, is widely used to treat influenza virus infections in inpatients and outpatients. A previous meta-analysis included only outpatients and patients suspected of having an influenza virus infection based on clinical symptoms. However, whether BXM or oseltamivir is safer and more effective for inpatients remains controversial. Therefore, we conducted a systematic review and meta-analysis validating the effectiveness and safety of BXM versus oseltamivir in inpatients with influenza virus. METHODS: The Scopus, EMBASE, PubMed, Ichushi, and CINAHL databases were systematically searched for articles published until January 2023. The outcomes were mortality, hospitalization period, incidence of BXM- or oseltamivir-related adverse events, illness duration, and changes of virus titers and viral RNA load in patients with influenza virus infections. RESULTS: Two randomized controlled trials with 1624 outpatients and two retrospective studies with 874 inpatients were enrolled. No deaths occurred in outpatients treated with BXM or oseltamivir. Among inpatients, BXM reduced mortality (p = 0.06) and significantly shortened hospitalization period (p = 0.01) compared to oseltamivir. In outpatients, BXM had a significantly lower incidence of adverse events (p = 0.03), reductions in influenza virus titers (p < 0.001) and viral RNA loads (p < 0.001), and a tendency to be a shorter illness duration compared with that of oseltamivir (p = 0.27). CONCLUSIONS: Our meta-analysis showed that BXM was safer and more effective in patients than oseltamivir; thus, supporting the use of BXM for the initial treatment of patients with proven influenza virus infection.

BACKGROUND: The use of antibiotic-loaded bone cement (ALBC) as a mean for preventing deep surgical site infections (SSI) after total joint replacement is controversial. Therefore, we have conducted a meta-analysis to evaluate the prophylactic effect of ALBC for SSI prevention in patients undergoing arthroplasty. This study was conducted to revise treatment guidelines for MRSA infections in Japan. METHODS: PubMed (Medline), Scopus, Embase, Web of Science and Cochrane library were searched for relevant articles comparing preventive effect of ALBC for patients undergoing primary total joint arthroplasty by August 2022. Primary outcome was the incidence of deep SSI. Subgroup analyses by type of surgery (total hip (THA) or knee (TKA) arthroplasty) and by causative pathogen (methicillin-resistant Staphylococcus aureus (MRSA)) were performed. RESULTS: Of the 3379 studies identified for screening, six studies involving 5745 patients were included. The use of ALBC significantly reduced the incidence of deep SSI in overall patients (risk ratio [RR] 0.60, 95% confidential interval [CI] 0.39-0.92), but the evidence level was very low. There was no significant preventive effect for ALBC compared with non-ALBC in both THA and TKA (THA, RR 0.52, 95% CI 0.23-1.16; TKA, RR 0.64, 95% CI 0.38-1.06), and for preventing MRSA-SSI (RR 0.27, 95% CI 0.03-2.41). CONCLUSIONS: Although the overall preventive effect of ALBC was significant, the evidence level was very low. Thus, the routine use of ALBC as a mean to prevent SSI in arthroplasty may not be suggested.

BACKGROUND: We investigated whether the initial voriconazole (VRCZ) dosing design, as determined using simulation software with a population pharmacokinetic model of Japanese patients, impacts the effectiveness and safety when compared with VRCZ initiation according to the package insert. METHODS: In this single-center retrospective observational study, we employed records from Tosei General Hospital (a 633-bed hospital), dated April 2017 to September 2023. Eligible patients were divided into the software-based simulation group, comprising patients administered initial VRCZ dosage adjustment by pharmacists using software-based simulation, and the standard therapy group, whose dosage was administered by a physician following the package insert recommendations without simulation. The primary objective of this study was to determine the efficacy of VRCZ first-dose design in reducing the incidence of hepatotoxicity and visual symptoms. RESULTS: The median ages of enrolled participants (n = 93) were 75 (68-79) and 72 (65-78) years in the software-based simulation and standard therapy groups, respectively. Regardless of formulation, initial trough concentrations were lower in the VRCZ software-based first dosage adjustment group and higher rate within the appropriate range (1-4 µg/mL). The incidence of all-grade hepatotoxicity or visual symptoms was significantly lower in the software-based simulation group. The log-rank test revealed a significant impact on the occurrence of ≥grade 2 hepatotoxicity in the software-based first dosage adjustment group compared to that in the standard therapy group. CONCLUSIONS: The initial VRCZ dosing design using simulation software improved the achievement of appropriate initial trough concentrations and resulted in fewer occurrences of hepatotoxicity (≥grade 2) when compared with the standard therapy.
RESUMO
INTRODUCTION: While respiratory syncytial virus (RSV) is one of the most common pathogens in adults admitted to the ICU due to respiratory diseases, no reports regarding the occurrence rate of RSV infections in adults in Japan during the COVID-19 pandemic exist. PATIENTS AND METHODS: We conducted this retrospective study to examine the exact occurrence rate of RSV infections in adults. We reviewed all patients (≥18 years) with any respiratory symptoms who received quantitative polymerase chain reaction (PCR) using nasopharyngeal samples for respiratory viruses by GeneLEAD at the Aichi Medical University Hospital between November 2022 and November 2023. RESULTS: A total of 541 adult patients who underwent PCR test were enrolled in this study. RSV was identified in 18 cases (3.3 %); 8 (1.5 %) upper and 10 (1.8 %) lower respiratory tract infections. Influenza A and SARS-CoV-2 were found in 10 (1.8 %) and 61 (11.3 %), respectively. Patients with RSV infections and COVID-19 had more comorbidities than those with Influenza virus infections. As for RSV-associated with lower respiratory tract infection cases, 10 developed acute respiratory failure, resulting in 1 fatal case due to pneumonia and 1 died of septic shock due to ileus. The 30-, 90-day mortality rates were 1 (6 %) and 2 (11 %) respectively. CONCLUSION: About 3 % of adults had RSV infections during the COVID-19 pandemic. The outcomes of RSV infections in adults were similar to those by COVID-19. Those with comorbidities should have a preventive method against RSV infections, the same as for COVID-19.
RESUMO
BACKGROUND: Isavuconazole is a novel triazole antifungal agent. However, the previous outcomes were highlighted by statistical heterogeneity. This meta-analysis aimed to validate the efficacy and safety of isavuconazole for the treatment and prophylaxis of invasive fungal infections (IFIs) compared with other antifungal agents (amphotericin B, voriconazole and posaconazole). METHODS: Scopus, EMBASE, PubMed, CINAHL and Ichushi databases were searched for relevant articles that met the inclusion criteria through February 2023. Mortality, IFI rate, discontinuation rate of antifungal therapy and incidence of abnormal hepatic function were evaluated. The discontinuation rate was defined as the percentage of therapy discontinuations due to adverse events. The control group included patients who received other antifungal agents. RESULTS: Of the 1784 citations identified for screening, 10 studies with an overall total of 3037 patients enrolled. Isavuconazole was comparable with the control group in mortality and IFI rate in the treatment and prophylaxis of IFIs, respectively (mortality, odds rate (OR) 1.11, 95% confidential interval (CI) 0.82-1.51; IFI rate, OR 1.02, 95% CI 0.49-2.12). Isavuconazole significantly reduced the discontinuation rate in the treatment (OR 1.96, 95% CI 1.26-3.07) and incidence of hepatic function abnormalities in the treatment and prophylaxis, compared with the control group (treatment, OR 2.31, 95% CI 1.41-3.78; prophylaxis, OR 3.63, 95% CI 1.31-10.05). CONCLUSIONS: Our meta-analysis revealed that isavuconazole was not inferior to other antifungal agents for the treatment and prophylaxis of IFIs, with substantially fewer drug-associated adverse events and discontinuations. Our findings support the use of isavuconazole as the primary treatment and prophylaxis for IFIs.

BACKGROUND: Chronic endometritis is a persistent inflammatory condition of the endometrium that negatively affects pregnancy outcomes. The Centers for Disease Control and Prevention guidelines recommend oral antibiotic treatment for chronic endometritis. However, a recent randomized controlled trial concluded that it was unclear whether antibiotic treatment improved pregnancy outcomes. Hence, we performed a systematic review and meta-analysis to validate the impact of oral antibiotic treatments on pregnancy outcomes among patients with chronic endometritis. METHODS: We systematically searched the PubMed, Scopus, Ichushi, CINAHL, and EMBASE databases until May 2021. We compared the pregnancy outcomes in patients with chronic endometritis with and without antibiotic treatment. We then focused on the implantation rate, intrauterine pregnancy rate, and live birth rate to evaluate pregnancy outcomes. RESULTS: Seven studies were included in the meta-analysis. Three hundred seventy-two patients were treated with antibiotics, while 1024 patients were not treated with antibiotics. Various antibiotic regimens were administered during the study period [14-21 days]. Antibiotic treatments for chronic endometritis did not increase the implantation rate (odds ratios [OR] 1.02, 95% confidence interval [CI], 0.78-1.33), intrauterine pregnancy rate (OR 1.08, 95% CI 0.72-1.63), or live birth rate (OR 1.13, 95% CI 0.65-1.97). CONCLUSIONS: Our meta-analysis proved that oral antibiotic treatment did not improve pregnancy outcomes in patients with chronic endometritis. Accordingly, further studies are needed to elucidate the treatment to improve pregnancy outcomes.

INTRODUCTION: Despite the advance in antibiotics and widespread chest tube drainage, acute empyema still shows a high mortality rate, accounting for 10-25%. We experienced a case of acute empyema caused by A. hydrophila, which is extremely uncommon, and reviewed all previously published articles. CASE PRESENTATION: A 76-year older man with a medical history of liver cirrhosis (LC) due to chronic hepatitis C and hepatic cell carcinoma was admitted to our institute. Elevated inflammatory reaction and effusions on chest CT were seen, and he was suspected of having acute empyema. Although an empiric antibiotic therapy of meropenem with chest tube drainage was performed as an initial treatment, he died within 8 hours of admission. Postmortem, both blood and left pleural fluid cultures yielded Aeromonas hydrophila. The final diagnosis was acute empyema caused by A. hydrophila. We reviewed previously reported empyema caused by Aeromonas species cases (4 A. hydrophila, and 1 A. veronii) in 4 previous reports written in English, including ours. Of 5, all were male, and the mean age was 52 years (range 27-76 years). All patients had LC due to alcohol or viral infections. As for antibiotics initially prescribed, third-generation cephalosporins were most frequently used in 3/5 (60%). Thoracentesis was performed in all patients (100%). As for prognosis, 2 (40%) survived, and 3 (60%) died. CONCLUSION: Physicians should be aware of the possibility of acute empyema caused by A. hydrophila among patients with chronic hepatic disease.

While acute empyema is a critical infectious disease showing a high mortality rate, there are no prognostic tools to evaluate the disease severity and prognosis for patients. We conducted a retrospective cohort to determine whether quick Sequential Organ Failure Assessment (qSOFA) and SOFA score can predict the disease severity and prognosis of acute empyema. A total of 53 patients were enrolled in the study. The mean age was 69 years and 41 patients (77%) were male. Twenty-two patients (42%) had multiple underlying diseases with the Charlson comorbidity index ≥3. The-30 days, and in-hospital deaths were 7 (13%) and 10 (19%), respectively. The area under the ROC curve of SOFA score and CCI for 30-day and in-hospital deaths were 0.814 (p = 0.073) and 0.752 (p = 0.082), 0.848 (p = 0.07) and 0.762 (p = 0.011), respectively. Univariate analysis showed that qSOFA ≥2 and SOFA score ≥2, isolation of potentially drug-resistant (PDR) pathogen, high CCI (≥3), performance status of 2-4, surgical intervention, and anaerobic bacteria involvement were prognostic factors. Of these, multivariate logistic regression analysis showed that qSOFA ≥2 and SOFA score ≥2 (p = 0.011), isolation of PDR pathogen (p = 0.005), and high CCI (≥3) (p = 0.015) were independently poor prognostic factors. We concluded that qSOFA and SOFA scores could predict the disease severity and prognosis in acute empyema. Additionally, isolation of PDR pathogens and high CCI could be poor prognostic factors for patients.

INTRODUCTION: Patients with nursing and healthcare-associated pneumonia (NHCAP) commonly receive empiric antibiotic therapy according to the guideline's recommendation corresponding to the patient's deteriorated conditions. However, it is unclear whether guideline-concordant treatment (GCT) could be effective or not. PATIENTS AND METHODS: To evaluate the efficacy and validity of GCT according to the current guideline for pneumonia, we conducted this retrospective study. NHCAP patients who were admitted to our institute between 2014 and 2017 were enrolled. Based on the initial antibiotic treatment, these patients were divided into two groups, the GCT group (n = 83) and the non-GCT group (n = 146). Propensity score matching (PSM) was used to balance the baseline characteristics and potential confounders between the two groups. After PSM, patients' characteristics, microbial profiles, and clinical outcomes were evaluated. RESULTS: Both groups were well-balanced after PSM, and 78 patients were selected from each group. There were no differences in patients' characteristics or microbial profiles between the two groups. As for outcomes, there were no differences in 30-day, in-hospital mortality rate, duration of antibiotic treatment, or admission. The severity of pneumonia was more severe in patients with the GCT group than those with the non-GCT group. Anti-pseudomonal agents as initial treatment were more frequently seen in patients with the GCT group than those in the non-GCT group. CONCLUSION: Unlike previous studies, GCT's recommendation for management of pneumonia by the JRS in 2017 would appear to be valid and does not increase the mortality rate.

INTRODUCTION: The pandemic of a novel coronavirus disease 2019 (COVID-19) caused by a severe acute respiratory coronavirus 2 (SARS-CoV-2) infection has been problematic worldwide. A new SARS-CoV-2 diagnostic test (SmartAmp) was licensed in Japan in July 2021. This method, which enables us to diagnose COVID-19 as well as a gene mutation on the virus, is promising to reduce medical costs and staff labor. PATIENTS AND METHODS: To analyze the diagnostic accuracy of the SmartAmp assay for diagnosing COVID-19, we performed this retrospective study at our institute during April and May 2021. We compared the results of the SmartAmp assay and real-time reverse transcription-polymerase chain reaction (rRT-PCR) using a saliva sample from individuals suspected as having COVID-19. RESULTS: Out of 70 samples tested, the SmartAmp assay had 50 (71%) positive and 20 (29%) negative results. Using rRT-PCR as a reference, the diagnostic accuracy displayed a sensitivity of 84%, a specificity of 95%, a positive predictive value of 97.7%, and a negative predictive value of 70.4%. On the other hand, false-negative cases were found in 7 (10%), and there was no significant difference of Ct-value between true positive and false negative cases (Mean Ct-value 25.2 vs. 27.5 cycles, p = 0.226 by Mann-Whitney U test). CONCLUSION: The SmartAmp assay is a valuable method to diagnose COVID-19 rapidly. However, the negative predictive value is not high enough to diagnose the disease, so that negative results should be considered for rRT-PCR testing if patients are suspected of having COVID-19.

The current guidelines suggest that hospital rooms previously occupied with Clostridioides difficile infection (CDI) patients should be decontaminated with recommended decontamination methods because C. difficile can persist on surfaces despite adherence to the recommended procedures. Recently, ultraviolet (UV) light and hydrogen peroxide have increasingly been used as innovative decontamination methods. Hence, we conducted a systematic review and meta-analysis to investigate which decontamination methods are effective in reducing environmental C. difficile contamination. We systematically searched the EMBASE, PubMed, CINAHL, Scopus, and Ichushi until March 11, 2021. We evaluated the efficacy of decontamination methods in terms of the frequency of C. difficile contamination on high-touch surfaces in hospital rooms and the incidence of hospital-acquired C. difficile infection. Among the 15 studies retrieved in our meta-analysis, eight evaluated decontamination methods with the frequency of C. difficile detection among samples after disinfection procedures, and eight reported the number of hospital-acquired CDI cases. Pooled analysis indicated that hydrogen peroxide significantly reduced the frequency of environmental C. difficile contamination, compared with hypochlorite (odds ratios [OR]: 0.12; 95% confidence interval [CI]: 0.07-0.23). Additionally, hydrogen peroxide reduced the incidence of hospital-acquired CDI compared to other methods (OR: 0.52; 95% CI: 0.28-0.96). Decontamination with UV significantly reduced the incidence of hospital-acquired CDI compared to hypochlorite (OR 0.52, 95% CI 0.28-0.96). The use of hydrogen peroxide and UV can help prevent environmental C. difficile contamination and transmission in healthcare facilities.

BACKGROUND: Candidemia has emerged as an important nosocomial infection, with a mortality rate of 30-50%. It is the fourth most common nosocomial bloodstream infection (BSI) in the United States and the seventh most common nosocomial BSI in Europe and Japan. The aim of this study was to assess the performance of the Sequential Organ Failure Assessment (SOFA) score for determining the severity and prognosis of candidemia. METHODS: We performed a retrospective study of patients admitted to hospital with candidemia between September 2014 and May 2018. The severity of candidemia was evaluated using the SOFA score and the Acute Physiology, Age, Chronic Health Evaluation II (APACHE II) score. Patients' underlying diseases were assessed by the Charlson Comorbidity Index (CCI). RESULTS: Of 70 patients enrolled, 41 (59%) were males, and 29 (41%) were females. Their median age was 73 years (range: 36-93 years). The most common infection site was catheter-related bloodstream infection (n=36, 51%).The 30-day, and in-hospital mortality rates were 36 and 43%, respectively. Univariate analysis showed that SOFA score ≥5, APACHE II score ≥13, initial antifungal treatment with echinocandin, albumin < 2.3, C-reactive protein > 6, disturbance of consciousness, and CCI ≥3 were related with 30-day mortality. Of these 7, multivariate analysis showed that the combination of SOFA score ≥5 and CCI ≥3 was the best independent prognostic indicator for 30-day and in-hospital mortality. CONCLUSIONS: The combined SOFA score and CCI was a better predictor of the 30-day mortality and in-hospital mortality than the APACHE II score alone.

INTRODUCTION: There has been no consensus on whether and how long add-on drugs for augmentation therapy should be continued in the treatment of depression. METHODS: Double-blind randomized controlled trials that examined the effects of discontinuation of drugs used for augmentation on treatment outcomes in patients with depression were identified. Meta-analyses were performed to compare rates of study withdrawal due to any reason, study-defined relapse, and adverse events between patients who continued augmentation therapy and those who discontinued it. RESULTS: Seven studies were included (n=841 for continuing augmentation therapy; n=831 for discontinuing augmentation therapy). The rate of study withdrawal due to any reason was not significantly different between the 2 groups (risk ratio [RR]=0.86, 95% confidence interval [CI]=0.69-1.08, p=0.20). Study withdrawal due to relapse was less frequent in the continuation group than in the discontinuation group (RR=0.61, 95% CI=0.40-0.92, p=0.02); however, this statistical significance disappeared when one study using esketamine as augmentation was excluded. Analysis of the data from 5 studies that included a stabilization period before randomization found less frequent relapse in the continuation group than in the discontinuation group (RR=0.47, 95% CI=0.36-0.60, p<0.01). This finding was repeated when the esketamine study was excluded. DISCUSSION: No firm conclusions could be drawn in light of the small number of studies included. Currently available evidence suggests that add-on drugs, other than esketamine, used for augmentation therapy for depression may be discontinued. This may not be the case for patients who are maintained with augmentation therapy after remission.

BACKGROUND: The incidence of linezolid-induced myelosuppression in pediatric patients was reported at large difference among prospective studies, with a range of 0-24%. Additionally, there is little study which evaluated the impact of linezolid administration period on myelosuppression in pediatric patients, while it is one of the most frequent reason that linezolid therapy has to be discontinued in adult patients. Here, we performed a systematic review and meta-analysis to reveal the incidence of linezolid-induced thrombocytopenia and anemia, and impact of the administration period of linezolid on myelosuppression based on individual data analysis of pediatric patients. METHODS: We systematically searched the Scopus, EMBASE, Cochrane Central Register of Controlled Trials, PubMed, and CINAHL until April 2020. We investigated the incidence of linezolid-induced thrombocytopenia and anemia using pooled analysis, and evaluated the impact of linezolid administration period on myelosuppression using meta-analysis. RESULTS: Thirteen studies with 969 pediatric patients were identified. The pooled incidences of thrombocytopenia and anemia were 9% (95% confidence interval (CI), 3-18%) and 4% (95% CI, 0-12%), respectively. Our meta-analysis showed the extension of linezolid administration period (more than 14 days) resulted in higher incidence of thrombocytopenia (OR 4.86, 95% CI 1.10-21.55) and anemia (OR 4.57, 95% CI 0.13-160.49). CONCLUSIONS: The incidence of linezolid-induced myelosuppression in pediatric patients was less than 10%. However, our meta-analysis revealed linezolid administration period for more than 14 days was one of risk factors associated with linezolid-induced myelosuppression. Therefore, especially for pediatric patients treated with linezolid for more than 14 days, careful monitoring of myelosuppression is required.

BACKGROUND: Current guidelines recommend echinocandins for the initial treatment of candidemia. However, polyenes are often chosen in clinical settings because of their fungicidal and anti-biofilm effects. Therefore, we performed a systematic review and meta-analysis to evaluate whether echinocandins are superior to polyenes in terms of mortality for the initial treatment of candidemia. METHODS: We systematically searched the Scopus, EMBASE, Cochrane Central Register of Controlled Trials, PubMed, and CINAHL databases until July 1, 2020. We compared the mortality rates of patients who received echinocandins and polyenes. As a subgroup analysis, we compared the mortality rates following the use of echinocandins versus liposomal amphotericin B. RESULTS: Fifteen studies involving 854 patients were included. Various Candida species were detected, and the rates of resistance of echinocandins and polyenes against the overall detected isolates were 1.0% and 0%, respectively. The overall mortality recorded in 15 studies was 41.0%, and the mortality was significantly higher for polyenes than echinocandins (odd ratios [OR] 1.68, 95% confidential interval [CI] 1.17-2.42). Furthermore, liposomal amphotericin B showed higher mortality in the initial treatment than echinocandins (OR 1.42; 95% CI 0.84-2.39). CONCLUSIONS: We revealed an association between echinocandin treatment and reduced mortality in the initial treatment of candidemia when causative fungi were not considered. Our findings partially support current guidelines recommending echinocandins for the treatment of candidemia.

BACKGROUND: Only a single meta-analysis has reported the clinical benefit of fluoroquinolones (FQs) for Legionella pneumonia; however, there is no robust data available to confirm this result, based on current guidelines. METHODS: We performed a systematic review and meta-analysis comparing FQs with macrolides (MCs) on their efficacy and safety in Legionella pneumonia, using studies published until January 2020. The outcomes included mortality (overall; 30-day), clinical cure, time to apyrexia, length of hospital stay, and adverse events. RESULTS: Five RCTs and twelve retrospective studies were identified. Clinical cure was comparable between the treatment groups (risk rate (RR) 1.07, 95% confidential interval (CI) 0.86-1.31). Mortality was significantly higher for MCs than for FQs (overall, odd rate (OR) 0.59, 95% CI 0.35-0.98; 30-day, OR 0.41, 95% CI 0.20-0.85). FQs significantly reduced the length of hospital stay, compared to MCs (mean difference -3.58, 95% CI -5.48-1.69). Other outcomes were not significantly different between the treatment groups (time to apyrexia; mean difference -1.83, 95% CI -5.15-1.5, adverse events; OR 0.61, 95% CI 0.33-1.15). In subgroup analyses, levofloxacin significantly reduced the length of hospital stay over two specific MCs (azithromycin and clarithromycin) (mean difference -3.03, 95% CI -5.33-0.72), whereas mortality was not significantly different between the treatment groups (overall, OR 0.49, 95% CI 0.19-1.24; 30-day, OR 0.38, 95% CI 0.13-1.13). CONCLUSIONS: FQs exhibited superior effects in terms of mortality and length of hospital stay in Legionella pneumonia. These results support current guidelines recommending FQs for the treatment of Legionella pneumonia.

INTRODUCTION: Aspiration pneumonia (AP) accounts for 5.0-53.2% of hospitalized pneumonia and the treatment commonly used is by broad-spectrum antibiotics to cover anaerobes. Since ceftriaxone (CTRX) could generally cover oral streptococcus and anaerobes implicated in AP, it could be a useful option in the treatment of AP, instead of piperacillin-tazobactam/(PIPC/TAZ) or Carbapenems. PATIENTS AND METHODS: For the purpose of examining whether CTRX is as effective as broad-spectrum antibiotics for the treatment of AP, this retrospective study included consecutive community-onset patients who were admitted to our institute between 2014 and 2017. These patients were divided into two groups, a CTRX group (n = 25) and a PIPC/TAZ or carbapenems group (n = 97) based on the initial antibiotic treatment. Propensity score matching (PSM) was used to balance the potential confounders, and 23 patients were selected from each group. Patients among CTXR group received CTRX, while those among PIPC/TAZ or carbapenems group received PIPC/TAZ, or carbapenems and/or other agents. RESULTS: Both groups were well-balanced after PSM. There were no differences in 30-day mortality, duration of hospital stay or antibiotic treatments in the between them. The medical costs were much more expensive in the PIPC/TAZ or carbapenems group than in the CTR group (35,582 v. s. 8678 Japanese yen, p < 0.001). CONCLUSION: CTRX is one of the most useful antibiotic treatment for AP, which is not inferior to broad-spectrum antibiotic treatment. In addition, usage of CTRX in the treatment of AP is more economical than broad-spectrum antibiotic treatment, and could contribute to reduction of medical costs.

INTRODUCTION: While the early diagnosis of necrotizing fasciitis (NF) is crucial and could lead to a favorable outcome, it is difficult to differentiate NF from cellulitis, resulting in delay for the appropriate treatment. PATIENTS AND METHODS: For the purpose of examining which diagnostic tools could correctly differentiate NF from cellulitis, we conducted this case-control study. We retrospectively reviewed all patients who were diagnosed with NF at our institute during 2014-2019. The patients who were diagnosed with cellulitis were randomly selected during the study period as the control group. The severity of NF is evaluated by serum-procalcitonin (PCT), LRINEC score, NTSI assessment and SIARI score. RESULTS: A total of 25 NF patients were enrolled in this study. The median age was 68 years (range 39-79) and 18 (72%) were male. Comparing NF and cellulitis groups, NF group showed a higher LRINEC score and serum PCT than cellulitis group did, even though there was no statistical significance in serum PCT. With respect to the diagnostic value for differentiating NF from cellulitis, the area under the ROC curve for of serum PCT and LRINEC scores were 0.928 [95% confidential interval (CI) 0.864-0.992, p < 0.001] and 0.846 (95% CI 0.757-0.936, p < 0.001). The appropriate serum-PCT cutoff value was 1.0 and had a sensitivity of 88%, a specificity of 89%, a positive predictive value of 81%, and a negative predictive value of 93%. CONCLUSION: Serum-PCT could be a useful diagnostic marker for differentiating diagnosis of NF from cellulitis.

INTRODUCTION: While necrotizing fasciitis (NF) is a rare but rapidly progressive devastating soft tissue infectious disease showing a high in-hospital mortality rate of 20-30%, there are no evidence-based predictive tools. PATIENTS AND METHODS: For the purpose of examining which predictive tools could correctly reflect the severity and prognosis of NF, we retrospectively reviewed all patients who were diagnosed with NF at our institute. The disease severity was evaluated by quick SOFA (qSOFA), SOFA score, SIRS score, APACHE II score, LRINEC score and the combined score of qSOFA and CCI. RESULTS: A total of 27 patients were enrolled in this study. The median age was 68 years (range 39-96 years). With respect to the predictive values for in-hospital mortality among NF patients, the area under the ROC curve for qSOFA, SOFA score, APACHE II score, the combined score of qSOFA and CCI were 0.653 (p = 0.192), 0.588 (p = 0.12), 0.709 (p = 0.075) and 0.782 (p = 0.016) respectively. A univariate analysis showed that the combined score of qSOFA and CCI≥5 and the initial treatment failure were poor prognostic indicators for the in-hospital death among NF patients. The appropriate cut-offs of qSOFA and CCI were based on the Youden Index. CONCLUSION: We concluded that the combined score of qSOFA and CCI could reflect the severity and prognosis of NF for in-hospital death.
