RESUMEN
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.

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.
RESUMEN
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.

Few studies have investigated the influence of more full-time equivalents (FTEs) of infectious disease (ID) pharmacists on the likelihood of a post-prescription review with feedback (PPRF) intervention. This study focused on this in community hospitals before and after the Japanese medical reimbursement system was revised to introduce antimicrobial stewardship (AS) fees. We collected data for two periods: before (April 2017 to March 2018) and after (April 2018 to March 2019) AS fee implementation. The efficacy of the PPRF by the ID pharmacist was assessed based on the usage of broad-spectrum antimicrobials in days of therapy (DOT) per 100 patient-days. Further, we generated the susceptibility rate for antimicrobial-resistant organisms. The number of PPRF drugs was 2336 (2596 cases) before AS fee implementation and 2136 (1912 cases) after implementation. The overall monthly FTE for AS for an ID pharmacist increased from [median (interquartile range; IQR)] 0.34 (0.33-0.36) to 0.63 (0.61-0.63) after AS fee implementation. The DOT of the broad-spectrum antibiotics decreased from 10.46 (9.61-12.48) to 8.68 (8.14-9.18). The DOT of carbapenems and quinolones decreased significantly from 4.11 (3.69-4.41) to 3.07 (2.79-3.22) and 0.96 (0.61-1.14) to 0.37 (0.19-0.46), respectively (p < 0.05). Furthermore, the rate of levofloxacin (LVFX)-susceptible Pseudomonas (P.) aeruginosa improved from 71.5 to 84.8% (p < 0.01). We observed that increasing the FTE of ID pharmacists influences the DOTs of broad-spectrum antibiotics; a higher FTE contributes to fewer DOTs. Further, the susceptibility of P. aeruginosa to meropenem and LVFX increased as the FTE increased.

INTRODUCTION: Monoclonal antibody therapy has been reported to be highly effective for preventing hospitalisation and severe cases in patients with Coronavirus Disease 2019 (COVID-19). However, since the drug is not readily available, it is important to rapidly and appropriately identify high-risk patients who can benefit most from therapy. Therefore, we designed a risk scoring system to identify at-risk COVID-19 patients in our region during the largest surge of COVID-19, from July to September 2021. METHODS: According to the risk scores, confirmed COVID-19 patients were introduced to receive REGN-CoV-2 to our hospital by regional health centre from 18th August (Term 3). The primary outcome was the comparison of the number of hospitalisation and severe condition with other periods, the 4th wave (Term 1) and the early part of the 5th wave (Term 2) in Japan. RESULTS: During Term 3, 115 patients were stratified with the scoring system and administered REGN-COV-2. The number of hospitalisation vs severe cases were 60 (5.2%) vs 14 (1.2%), 8 (1.5%) vs 3 (0.6%) and 21 (1.2%) vs 2 (0.1%), in term 1, 2 and 3, respectively. Among those aged <60 years, compared with term 1, the relative risk of hospitalisation and severe condition were 0.25 (95% CI: 0.12-0.53) and 0.10 (95% CI: 0.01-0.80), respectively, in term 3. Drug adverse events were fever (3: 2.6%), headache (1: 0.9%) and neck rash (1: 0.9%), all events were resolved within 24 h wth no serious adverse event. CONCLUSIONS: The administration of monoclonal antibody therapy using a risk scoring system significantly reduced the number of hospitalisation and disease severity of COVID-19 without any serious adverse events and avoided regional medical collapse.

PURPOSE: In order to detect cancer therapeutics-related cardiac dysfunction (CTRCD) early, we identified which drugs were to be monitored using signal detection and the package insert, and created and applied a protocol to address this. METHODS: Adverse event data recorded in the Japanese Adverse Drug Event Report (JADER) database between April 2004 and January 2018 were used. Among small molecule tyrosine kinase inhibitors that are not described in the serious side-effects section of the package insert despite signal detection, tyrosine kinase inhibitors with severe side-effects in the background of cases reported by JADER database were selected to be monitored in clinical practice. We applied our findings clinically by creating a protocol to detect CTRCD early. All cases at Tosei General Hospital where the target tyrosine kinase inhibitors were administered from when they were first released in November 2019 were included. We compared the results from before and after we began the protocol to clarify its effects. RESULTS: We found that CTRCD was not described in the serious side-effect section of the package inserts for Bosutinib, Alectinib, and Osimertinib even though CTRCD signals were detected for them. Therefore, it is possible that we may have previously overlooked CTRCD. When we applied our protocol using Osimertinib as the target drug, we were able to detect CTRCD early in 5/21 (24%) patients. CONCLUSIONS: It was clarified that the drug identification method used in this study for early detection of adverse events leads to early detection of adverse events when applied clinically.

The presence of anaerobes in the blood stream is known to be associated with a higher rate of mortality. However, few prognostic risk factor analyses examining whether a patient's background characteristics are associated with the prognosis have been reported. We performed a retrospective case-controlled study to assess the prognostic factors associated with death from anaerobic bacteremia. Seventy-four patients with anaerobic bacteremia were treated between January 2005 and December 2014 at Aichi Medical University Hospital. The clinical information included drug susceptibility was used for analysis of prognostic factors for 30-day mortality. Multivariate logistic analyses revealed an association between the 30-day mortality rate and malignancy (OR: 3.64, 95% CI: 1.08-12.31) and clindamycin resistance (OR: 7.93, 95% CI: 2.33-27.94). The result of Kaplan-Meier analysis of mortality showed that the 30-day survival rate was 83% in clindamycin susceptible and 38.1% in clindamycin resistant anaerobes causing bacteremia. The result of log-rank test also showed that susceptibility to clindamycin affected mortality (P < 0.001). Our results indicated that malignancy and clindamycin susceptibility could be used to identify subgroups of patients with anaerobic bacteremia with a higher risk of 30-day mortality. The results of this study are important for the early and appropriate management of patients with anaerobic bacteremia.

BACKGROUND: Many case series studies have reported risk factors of infection with anaerobic bacteria, but few factor analysis studies have been conducted. OBJECTIVE: We conducted a case-control study to identify the risk factors of anaerobic bacteremia. METHODS: We compared a number of characteristics of patients with anaerobic bacteremia with those with aerobic bacteremia. Clinical information for 71 patients of anaerobic bacteremia was collected from January 1999 to December 2012 in Aichi Medical University Hospital. For each case, we identified up to four controls matched by the time of the positive blood culture. RESULTS: Multivariate logistic analyses revealed an association between anaerobic bacteremia and malignancy (OR: 3.35, 95% CI: 1.85-6.09), Douglas' pouch drains (OR: 25.90, 95% CI: 2.90-25.00) and chest drains (OR: 3.35, 95% CI: 1.19-9.43) as the primary causative disease, as well as associations between anaerobic bacteremia and the gastrointestinal tract (OR: 3.29, 95% CI: 1.38-7.81), genitourinary tract (OR: 4.98, 95% CI: 2.06-12.05), Douglas' pouch drains (OR: 16.95, 95% CI: 1.82-166.67) and chest drains (OR: 3.62, 95% CI: 1.29-10.20) as the primary causative organs. On the other hand, our study showed that having a central venous catheter was not associated with anaerobic bacteremia. CONCLUSIONS: We demonstrated an association between anaerobic bacteremia and malignancy, gastrointestinal and genitourinary tracts, patients having a Douglas' pouch drains or chest drains. These findings may be useful for developing early appropriate management for anaerobic bacteremia.

Objectives: We performed a comprehensive systematic review and meta-analysis to evaluate the clinical or microbiological outcomes and safety of a combination of daptomycin (DAP) and ß-lactams compared to DAP monotherapy in patients with blood stream infection (BSI) due to gram-positive cocci (GPC). Methods: We searched Scopus, PubMed, EMBASE, CINAHL, and Ityuushi databases up to January 30, 2023. Outcomes included all-cause mortality, clinical failure, and creatine phosphokinase (CPK) elevation. Results: Six cohorts or case-control studies fulfilled the inclusion criteria and were included in the final meta-analysis. Combination therapy of DAP and ß-lactams significantly reduced the mortality and clinical failure rate for all BSI due to GPC compared with the DAP monotherapy (mortality, odds ratio [OR] = 0.63, 95 % confidence interval [CI] = 0.41-0.98; clinical failure, OR = 0.42, 95 % CI = 0.22-0.81). In contrast, no significant difference was noted in the incidence of CPK elevation between the two groups (OR = 0.85, 95 % CI = 0.39-1.84). Conclusion: Altogether, combination therapy of DAP and ß-lactams can improve the prognosis for patients with BSI due to GPC compared with DAP alone. Therefore, it should be considered as an option for the empirical treatment of BSI caused by GPC.
RESUMEN
Although nirmatrelvir/ritonavir (NMV/r) reportedly increases blood levels of tacrolimus (TAC) due to CYP3A4 inhibition and other factors, reports on the use of NMV/r in combination with tacrolimus hydrate extended-release capsules (TAC-ER) in lung transplant patients are limited. Herein, we present a case with post-lung transplantation of elevated blood trough levels of TAC after concomitant use of NMV/r. A woman in her 60s had undergone lung transplantation. She had coronavirus disease 2019 (COVID-19) and was co-administered NMV/r and TAC-ER, with the trough level controlled at approximately 4 µg/mL. Upon the co-administration of NMV/r and TAC-ER, the patient developed diarrhea and vomiting and was hospitalized. TAC-ER was discontinued on day 6, and TAC level was measured on day 8 and had risen above 100 ng/mL. This level gradually decreased to 17.8 ng/mL on day 11 and 2.4 ng/mL on day 15; therefore, TAC-ER was resumed at 2.5 mg/day. On day 18, the TAC level was 5.2 ng/mL, which was within the target range, and the patient was discharged on day 19. This is the first report of a post-lung transplant patient co-administered TAC-ER with NMV/r, who showed abnormally high blood TAC levels above the detection limit. In patients using TAC-ER after lung transplantation, it may be useful to confirm that the TAC blood level is below the effective therapeutic range before resuming TAC-ER safely.
RESUMEN
Despite advances in medical technology, lung cancer still has one of the highest mortality rates among all malignancies. Therefore, efforts must be made to understand the precise mechanisms underlying lung cancer development. In this study, we conducted lung and gut microbiome analyses and a comprehensive lipid metabolome analysis of host tissues to assess their correlation. Alternations in the lung microbiome due to lung cancer, such as a significantly decreased abundance of Firmicutes and Deferribacterota, were observed compared to a mock group. However, mice with lung cancer had significantly lower relative abundances of Actinobacteria and Proteobacteria and higher relative abundances of Cyanobacteria and Patescibacteria in the gut microbiome. The activations of retinol, fatty acid metabolism, and linoleic acid metabolism metabolic pathways in the lung and gut microbiomes was inversely correlated. Additionally, changes occurred in lipid metabolites not only in the lungs but also in the blood, small intestine, and colon. Compared to the mock group, mice with lung cancer showed that the levels of adrenic, palmitic, stearic, and oleic (a ω-9 polyunsaturated fatty acid) acids increased in the lungs. Conversely, these metabolites consistently decreased in the blood (serum) and colon. Leukotriene B4 and prostaglandin E2 exacerbate lung cancer, and were upregulated in the lungs of the mice with lung cancer. However, isohumulone, a peroxisome proliferator-activated receptor gamma activator, and resolvin (an ω-3 polyunsaturated fatty acid) both have anti-cancer effects, and were upregulated in the small intestine and colon. Our multi-omics data revealed that shifts in the microbiome and metabolome occur during the development of lung cancer and are of possible clinical importance. These results reveal one of the gut-lung axis mechanisms related to lung cancer and provide insights into potential new targets for lung cancer treatment and prophylaxis.
RESUMEN
Tuberculous otitis media (TOM) is a rare manifestation caused by Mycobacterium tuberculosis with low incidence rates among extrapulmonary tuberculosis cases. Diagnosis is often delayed because of the presence of several clinical manifestations and the high prevalence of secondary bacterial infections. Few reports have attributed secondary bacterial infections in patients with TOM to commensal Neisseria. Thus, understanding the pathogenic mechanisms and clinical features of commensal Neisseria is important, considering its recent presentation as an infection-causing pathogen. Neisseria mucosa is a commensal inhabitant in humans and is generally considered non-pathogenic but can cause infection in rare cases. Here, we report an atypical secondary infection caused by Neisseria mucosa in an 81-year-old woman with TOM being treated for pulmonary tuberculosis. Direct purulent otorrhea smear microscopy revealed no acid-fast bacilli using Ziehl-Neelsen staining, whereas the phagocytosis of gram-negative cocci by white blood cells was confirmed using Gram staining. Otorrhea culture revealed the growth of N. mucosa. Subsequently, M. tuberculosis infection in the otorrhea was identified using a culture-based method. Vigilance is critical for the early detection of TOM to prevent further complications. This report raises awareness regarding TOM and provides insight into the pathogenicity of N. mucosa in otitis media.
RESUMEN
Endometritis occurs frequently in humans and animals, which can negatively affect fertility and cause preterm parturition syndrome. Orally administered Clostridium butyricum, a butyrate-producing gram-positive anaerobe, exhibits anti-inflammatory effects. However, the precise mechanism by which Clostridium butyricum attenuates endometritis remains unclear. This in vivo study evaluated the anti-inflammatory effects of orally administered Clostridium butyricum on uterine tissues. In addition, we conducted uterine microbiome and lipid metabolome analyses to determine the underlying mechanisms. Female Balb/c mice were divided into the following four groups (n = 5-20): (1) mock group, (2) only operation group (mice only underwent operation to exposed uterine horns from the side), (3) control group (mice underwent the same operation with the operation group + perfusion of lipopolysaccharide solution from uterine horns), and (4) Clostridium butyricum administration group (mice underwent the same operation with the control group + oral Clostridium butyricum administration from days 0 to 9). Clostridium butyricum was administered via oral gavage. On day 10, we investigated protein expression, uterine microbiome, and lipid metabolism in uterine tissues. Consequently, orally administered Clostridium butyricum altered the uterine microbiome and induced proliferation of Lactobacillus and Limosilactobacillus species. The effects can contribute to show the anti-inflammatory effect through the interferon-ß upregulation in uterine tissues. Additionally, oral Clostridium butyricum administration resulted in the upregulations of some lipid metabolites, such as ω-3 polyunsaturated fatty acid resolvin D5, in uterine tissues, and resolvin D5 showed anti-inflammatory effects. However, the orally administered Clostridium butyricum induced anti-inflammatory effect was attenuated with the deletion of G protein-coupled receptor 120 and 15-lipooxgenase inhibition. In conclusion, Clostridium butyricum in the gut has anti-inflammatory effects on uterine tissues through alterations in the uterine microbiome and lipid metabolism. This study revealed a gut-uterus axis mechanism and provided insights into the treatment and prophylaxis of endometritis.
RESUMEN
BACKGROUND: Accurate diagnosis of prosthetic joint infection (PJI) enables early and effective treatment. However, there is currently no gold standard test for microbial detection of PJI and traditional synovial fluid culture is relatively insensitive. Recently, it has been reported that sonicating fluid culture and next-generation sequencing (NGS) improve microbial detection rates. Hence, we performed a systematic review and meta-analysis to compare microbial detection rates in microbial culture methods with and without sonication versus NGS. METHODS: We systematically searched EMBASE, PubMed, Scopus, CINAHL, and Ichushi databases and other sources (previous reviews) until August 2022. We evaluated the detection rates of pathogens in NGS and microbial cultures using samples of synovial or sonicated fluid. RESULTS: Of the 170 citations identified for screening, nine studies were included. Pooled analysis indicated that NGS had the highest detection rate among the microbial detection methods (NGS vs. sonicated, odds ratios [OR] 5.09, 95% confidential interval [CI] 1.67-15.50; NGS vs. synovial, OR 4.52, 95% CI 2.86-7.16). Sonicated fluid culture showed a higher detection rate than synovial fluid culture (OR 2.11, 95% CI 1.23-3.62). CONCLUSION: NGS might be useful as a screening tool for culture-negative patients. In clinical settings, sonicated fluid culture is a practical method for diagnosing PJI.

BACKGROUND: Recombinant human soluble thrombomodulin (rhTM) is used to treat sepsis-induced disseminated intravascular coagulation (DIC). However, no consistent clinical guidelines exist regarding the administration of rhTM in patients with sepsis-induced DIC. Therefore, we conducted this meta-analysis to evaluate the efficacy and safety of rhTM therapy in patients with sepsis-induced DIC. METHODS: EMBASE, PubMed, Scopus, Ichushi, and CINAHL databases were used to search for relevant articles that met the inclusion criteria of patients with sepsis-induced DIC treated with and without rhTM through November 2022. Mortality, DIC resolution, and incidence of bleeding complications were evaluated. DIC resolution was defined as the recovery from DIC after the start of DIC treatment. RESULTS: Of the 1697 citations identified for screening, 17 studies involving 2296 patients were included. Administering rhTM significantly reduced mortality (odds ratio (OR) 0.54, 95 % confidence interval (CI) 0.42-0.71) and improved DIC resolution (OR 2.88, 95 % CI 1.83-4.52). There were no significant differences in the incidence of bleeding complications between the rhTM and control groups (OR 0.92, 95 % CI 0.66-1.28). CONCLUSIONS: Our meta-analysis revealed that rhTM could reduce mortality and improve DIC resolution without increasing the risk of bleeding in patients with sepsis-induced DIC. Our findings suggest that rhTM is a relatively effective and safe anticoagulant for the treatment of sepsis-induced DIC. SUMMARY: Recombinant human soluble thrombomodulin reduced mortality without increasing the bleeding risk in the treatment of sepsis-induced disseminated intravascular coagulation.

The human body is host to a large number of commensal microbial species such as bacteria, fungi, and viruses. Among these, the human mycobiome is often neglected as a potential cause of disease, as it is thought to be comparatively much less abundant and less diverse than the human bacteriome. Additionally, most fungi are not easily cultured, even in specific media. Hence, their study has been limited to date, mainly because of the unavailability of methods used for their detection. However, the utilization of a novel metagenomic methodology will enable the identification of well-characterized mycobiomes in several parts of the human body and broaden our knowledge of their contribution to human health and disease. In this article, we review the role of the human mycobiome in the gut, respiratory organs, skin, genital tract, and carcinogenesis, highlighting the correlations between the human mycobiome and mycobiome-associated diseases.

Molnupiravir (MOV) and nirmatrelvir/ritonavir (NMV/r) are efficacious oral antiviral agents for patients with the 2019 coronavirus (COVID-19). However, little is known about their effectiveness in older adults and those at high risk of disease progression. This retrospective single-center observational study assessed and compared the outcomes of COVID-19 treated with MOV and NMV/r in a real-world community setting. We included patients with confirmed COVID-19 combined with one or more risk factors for disease progression from June to October 2022. Of 283 patients, 79.9% received MOV and 20.1% NMV/r. The mean patient age was 71.7 years, 56.5% were men, and 71.7% had received ≥3 doses of vaccine. COVID-19-related hospitalization (2.8% and 3.5%, respectively; p = 0.978) or death (0.4% and 3.5%, respectively; p = 0.104) did not differ significantly between the MOV and NMV/r groups. The incidence of adverse events was 2.7% and 5.3%, and the incidence of treatment discontinuation was 2.7% and 5.3% in the MOV and NMV/r groups, respectively. The real-world effectiveness of MOV and NMV/r was similar among older adults and those at high risk of disease progression. The incidence of hospitalization or death was low.

Severely ill intensive care unit (ICU) patients are frequently at risk of developing methicillin-resistant Staphylococcus aureus (MRSA) infections. It is generally accepted that a trough level of >10 µg/mL teicoplanin (TEC) is appropriate for most such infections. The present study was designed to determine how TEC exposure and patient characteristics affect microbiological response in the treatment of MRSA infections. All patients studied were admitted to Aichi Medical University Hospital ICU between May 2005 and April 2010. Fifty-nine patients were prescribed TEC and 33 of those patients used to treat MRSA infection. Outcome was classified as either cure or failure, and logistic regression analysis was performed to determine which covariates, including severity, significantly influenced the microbiological response. Satisfactory outcomes were obtained in 19 of the 33 patients. Although the cured and failed groups showed adequate trough concentrations, the area under the serum concentration curve (AUC(0-24)) on the third day was significantly higher for the cured group (897.6 ± 71.7) than for the failed group (652.9 ± 83.4) (p < 0.05). The results suggested that at least 800 µg h/mL TEC AUC(0-24) were required to obtain microbiological cure. The higher AUC(0-24), the better the outcome. In our study, higher initial AUC(0-24) was associated with a better microbiological outcome, which demonstrates the importance of the loading dose of TEC, especially for ICU patients. Moreover, the present findings are useful for optimizing the individual dose of TEC using AUC(0-24) in the treatment of MRSA-infected patients.

The pharmacokinetics-pharmacodynamics (PK-PD) breakpoint of piperacillin/tazobactam (PIPC/TAZ) for hospital-acquired pneumonia (HAP) and Pseudomonas aeruginosa-induced bacteremia is controversial, since the susceptibility of P. aeruginosa to PIPC/TAZ is known to be lower than that set by the Clinical Laboratory Standards Institute (CLSI), ≤64 mg/L. The association between MIC levels and bacterial eradication after various PIPC/TAZ treatments was investigated. In all, 61 and 17 Japanese patients from the microbiology laboratory database with HAP and P. aeruginosa-induced bacteremia, respectively, who were treated with PIPC/TAZ (4.5 g, b.i.d., t.i.d., or q.i.d.) between 2008 and 2009 were retrospectively analyzed. Pertinent clinical data were retrieved from medical records. The MIC level was determined using the microdilution method. Appropriate empirical therapy with PIPC/TAZ was selected for all patients within 24 h of positive culture results. The microbiological effect after treatment was used to determine the efficacy of each PIPC/TAZ administration method. In PIPC/TAZ-treated HAP patients (4.5 g, t.i.d.), the microbiological efficacy was 93.3% (28/30) when the MIC was ≤16 mg/L, while it was 50.0 (5/9) and 0% (0/3) with MICs of 32 (p < 0.05) and 64 mg/L, respectively. In PIPC/TAZ-treated bacteremia patients (4.5 g, t.i.d. or q.i.d.), the microbiological efficacy was 100% (11/11) when the MIC was <16 mg/L, while it was 33.3 (1/3) and 0% (0/3) with MICs of 32 (p < 0.05) and ≥64 mg/L, respectively. The present CLSI susceptibility breakpoints do not necessarily predict clinical outcomes. The appropriateness evaluation of the current CLSI resistance breakpoint of PIPC/TAZ and the PK-PD breakpoint determination warrant further studies.
