Abstract
INTRODUCTION A target trough concentration (Cmin) of teicoplanin ≥ 15-20 mg/L between the fourth and sixth day has been suggested for severe infections or management of febrile neutropenia (FN). Owing to no reports discussing the impact of early target attainment on treatment outcomes, this study aimed to evaluate the dose-Cmin relationship and clinical outcome and estimate the optimal early target Cmin for FN in patients with hematological malignancies. METHODS This single-center, prospective study enrolled patients with hematological malignancies who were treated with teicoplanin either as an empirical antibiotic for FN or as targeted treatment for Gram-positive bacteria. Blood samples were collected on day three (48 h) post-loading doses, day 5 (96 h), and day 8 (when applicable) and determined by ultrahigh-pressure liquid chromatography-triple quadruple mass spectrometry. A total of 117 samples from 47 patients with FN (27 men, 20 women) were consecutively analyzed. A two-tailed α value of 0.05 was considered statistically significant. RESULTS The mean Cmin values at 48 h, 96 h, and on day 8 were 23.4, 21.4, and 27.8 mg/L, respectively. The patients achieving Cmin ≥ 20 mg/L at 48 h had a higher likelihood of treatment success. The areas under the receiver operating characteristic curves were 0.71 for clinical efficacy and the cutoff value of Cmin at 48 h was 18.85 mg/L (95% confidence interval 0.55-0.87; P = 0.018). CONCLUSIONS The Cmin of teicoplanin after completion of loading doses could predict the treatment response, with a target concentration ≥ 18.85 mg/L.

Beyond One-Size-Fits-All: Tailoring Teicoplanin Regimens for Normal Renal Function Patients Using Population Pharmacokinetics and Monte Carlo Simulation. Pharmaceutics 2024; 16:499. [PMID: 38675160 PMCID: PMC11053983 DOI: 10.3390/pharmaceutics16040499] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2024] [Revised: 03/31/2024] [Accepted: 04/03/2024] [Indexed: 04/28/2024] Open
Abstract
In patients with normal renal function, significant teicoplanin dose adjustments are often necessary. This study aimed to develop a population pharmacokinetic (PK) model for teicoplanin in healthy adults and use it to recommend optimal dosage regimens for patients with normal renal function. PK samples were obtained from 12 subjects and analyzed using a population approach. The derived parameters informed Monte Carlo simulations for dosing recommendations. The PK profile was best described using a three-compartment model, in which the estimated glomerular filtration rate calculated via the CKD-EPI equation and adjusted for body surface area was identified as a significant covariate affecting total clearance. For pathogens with a minimum inhibitory concentration of 1 mg/L, a loading dose (LD) of 14 mg/kg administered every 12 h for four doses, followed by a maintenance dose (MD) of 16 mg/kg administered every 24 h, is recommended. These findings indicate the need for dosage adjustments, such as increasing the LD and MD or decreasing the dosing interval of MD in patients with normal renal function. Because of the long half-life of teicoplanin and the requirement for long-term administration, therapeutic drug monitoring at strategic intervals is important to avoid nephrotoxicity associated with elevated trough concentrations.

Abstract
Background Owing to its low risk of adverse effects, teicoplanin has been extensively used in patients with infections caused by MRSA. To promote the better management of patients receiving teicoplanin, we have updated the guidelines for therapeutic drug monitoring (TDM). Methods The guidelines were developed by a committee following the methodology handbook published by the Japanese Medical Information Distribution Service. Nine clinical questions were selected. The committee conducted a systematic review and meta-analysis to establish evidence-based recommendations for the target trough concentration (Cmin). An initial electronic database search returned 515 articles, and 97 articles qualified for a full review. Four and five studies were included for the efficacy evaluation of cut-off Cmin values of 15 and 20 mg/L, respectively. Results Compared with Cmin < 15 mg/L, a target Cmin value of 15–30 mg/L resulted in increased clinical efficacy in patients with non-complicated MRSA infections (OR = 2.68; 95% CI = 1.14–6.32) without an increase in adverse effects. Although there was insufficient evidence, target Cmin values of 20–40 mg/L were suggested in patients with complicated or serious MRSA infections. A 3 day loading regimen followed by maintenance treatment according to renal function was recommended to achieve the target trough concentrations. Because of the prolonged half-life of teicoplanin, measurement of the Cmin value on Day 4 before reaching steady state was recommended. Conclusions The new guideline recommendations indicate the target Cmin value for TDM and the dosage regimen to achieve this concentration and suggest practices for specific subpopulations.

Front Med (Lausanne) 2021; 8:748769. [PMID: 34926498 PMCID: PMC8671752 DOI: 10.3389/fmed.2021.748769] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2021] [Accepted: 11/05/2021] [Indexed: 11/22/2022] Open
Abstract
Objectives: Our ex vivo study was designed to determine the sequestration of teicoplanin, tigecycline, micafungin, meropenem, polymyxin B, caspofungin, cefoperazone sulbactam, and voriconazole in extracorporeal membrane oxygenation (ECMO) circuits. Methods: Simulated closed-loop ECMO circuits were prepared using 2 types of blood-primed ECMO. After the circulation was stabilized, the study drugs were injected into the circuit. Blood samples were collected at 2, 5, 15, 30 min, 1, 3, 6, 12, and 24 h after injection. Drug concentrations were measured by high-performance liquid chromatography-tandem mass spectrometry. Control groups were stored at 4°C after 3, 6, 12, and 24 h immersing in a water bath at 37°C to observe spontaneous drug degradation. Results: Twenty-six samples were analyzed. The average drug recoveries from the ECMO circuits and control groups at 24 h relative to baseline were 67 and 89% for teicoplanin, 100 and 145% for tigecycline, 67 and 99% for micafungin, 45 and 75% for meropenem, 62 and 60% for polymyxin B, 83 and 85% for caspofungin, 79 and 98% for cefoperazone, 75 and 87% for sulbactam, and 60 and 101% for voriconazole, respectively. Simple linear regression showed no significant correlation between lipophilicity (r2 = 0.008, P = 0.225) or the protein binding rate (r2 = 0.168, P = 0.479) of drugs and the extent of drug loss in the ECMO circuits. Conclusions: In the two ECMO circuits, meropenem and voriconazole were significantly lost, cefoperazone was slightly lost, while tigecycline and caspofungin were not lost. Drugs with high lipophilicity were lost more in the Maquet circuit than in the Sorin circuit. This study needs more in vivo studies with larger samples for further confirmation, and it suggests that therapeutic drug concentration monitoring should be strongly considered during ECMO.

Abstract
BACKGROUND The concurrent use of vancomycin and piperacillin/tazobactam increases the risk of acute kidney injury (AKI) compared with vancomycin use with other anti-pseudomonal β-lactams (OAPBs). Teicoplanin is a glycopeptide antibiotic with lower nephrotoxicity than that of vancomycin. Whether the concomitant use of teicoplanin and piperacillin/tazobactam also increases the risk of AKI remains unknown. OBJECTIVES To evaluate the AKI risk between teicoplanin-piperacillin/tazobactam and teicoplanin-OAPBs. METHODS This was a retrospective, propensity score-matched cohort study. Adult patients receiving teicoplanin-based combination therapy were included. OAPBs included cefepime, cefoperazone/sulbactam, ceftazidime, doripenem, imipenem/cilastatin and meropenem. Propensity score matching was performed to balance demographic and confounding factors. The primary endpoint was AKI during combination therapy. RESULTS After propensity score matching, 954 patients (teicoplanin-piperacillin/tazobactam: teicoplanin-OAPBs, 1:3 matched, 243 pairs in total) were included for analysis. The mean age was 66.3 years in the matched cohort and 17.1% of patients had shock. Use of nephrotoxic medications (45.7% versus 48.7%) and baseline renal function (78.88 ± 31.26 versus 81.05 ± 31.53 mL/min/1.73 m2) were similar in the two groups. The median teicoplanin dose was 10.7 mg/kg in both groups. The groups did not differ significantly in terms of AKI risk (14.8% versus 14.2%, P = 0.815). However, the time to AKI appeared shorter in the teicoplanin-piperacillin/tazobactam group (4.64 ± 2.33 versus 6.29 ± 4.72 days, P = 0.039). CONCLUSIONS The combination of teicoplanin and piperacillin/tazobactam was not associated with an increased risk of AKI compared with teicoplanin and OAPBs.

Abstract
BACKGROUND The optimal loading dose of teicoplanin in patients receiving venoarterial extracorporeal membrane oxygenation (VA-ECMO) has never been determined by therapeutic drug monitoring. This study investigated the appropriateness of proposed loading dose regimens of teicoplanin when administered to patients receiving VA-ECMO by using a previously proposed loading dosage and measuring the teicoplanin trough concentration (Ctrough). METHODS Patients who initiated teicoplanin therapy while receiving VA-ECMO were enrolled. Every included patient received four loading doses of teicoplanin at a dose of 12 mg/kg. The first three doses were administered 12 h apart, and the fourth dose was administered 24 h after the third dose. Blood samples were collected before administering the maintenance dose (i.e., the fifth dose), and the teicoplanin Ctrough was measured. Serum teicoplanin levels were determined using an Agilent 1290 ultra-high performance liquid chromatography system. RESULTS The teicoplanin Ctrough was successfully tested in 11 patients. Their median age was 68.2 years, and 81.8% of them were men. The median of each loading dose was 11.6 (range, 10.7-12.8) mg/kg. The median teicoplanin Ctrough was 22.01 (range, 14.85-44.84) mg/L. All patients had a Ctrough of more than 10 mg/L, whereas 90.9% (10/11) of the patients achieved a Ctrough of more than 15 mg/L. CONCLUSION The loading dosage consisting of four doses of teicoplanin administered within the first 72 h at a dose of 12 mg/kg/dose could achieve an adequate therapeutic Ctrough of teicoplanin in patients receiving VA-ECMO.

Abstract
Teicoplanin is used for the treatment of Methicillin-resistant Staphylococcus aureus infection. It has been demonstrated that conventional loading regimen was insufficient for teicoplanin to achieve target trough plasma concentration (Cmin > 10 mg/L). Therefore, a Chinese expert group recommended an optimal loading dose regimen of teicoplanin to treat severe Gram-positive infection. However, there was no report about the teicoplanin concentration, and the safety and efficacy of teicoplanin therapy in Chinese patients since the consensus was published. The objective of this study was to compare the teicoplanin Cmin and clinical response in critically ill Chinese patients after the administration of conventional or optimal loading regimen, and to reveal the potential factors that may affect teicoplanin Cmin in addition to loading regimen. Fifty-five patients were retrospectively divided into two groups based on teicoplanin loading regimen: (a) CD group (conventional loading dose group, n = 18, loading dose was 400 mg); (b) OD group (optimal loading dose group, n = 37, loading dose was 800 mg). Initially, three loading doses were administered every 12 hours, while the fourth loading dose was injected 24 hours after the third dose. The maintenance dose was 400 mg (CD group) or 800 mg (OD group), respectively. The mean teicoplanin Cmin on day 2 and day 4 in the OD group was significantly higher than those in the CD group, which were 14.75 ± 5.93 mg/L vs 8.26 ± 4.87 mg/L (P < .001) and 14.90 ± 5.20 mg/L vs 9.13 ± 4.75 mg/L (P = .019), respectively. The percentages of patients in the OD group achieving the target teicoplanin Cmin on day 2 and day 4 were also significantly higher than those in the CD group, which were 83.7% vs 33.3% (P < .001) and 82.4% vs 28.6% (P = .0013), respectively. Furthermore, multivariate linear regression analysis showed that body-weight exerted significant effect on teicoplanin Cmin in the OD group. The percentage of favourable clinical response in the OD group was significantly higher than that in the CD group (83.8% vs 55.6%, P = .025). There was no difference between teicoplanin adverse effects in the two groups. The study demonstrated that the optimal loading dose regimen of teicoplanin can rapidly reach target Cmin , and result in a good clinical efficacy and low adverse effect in critically ill Chinese patients.

Basic Clin Pharmacol Toxicol 2018; 123:594-601. [PMID: 29702731 DOI: 10.1111/bcpt.13029] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2018] [Accepted: 04/16/2018] [Indexed: 12/26/2022]
Abstract
This study used high-performance liquid chromatography to measure 202 teicoplanin plasma trough concentrations (Cmin ) in 114 haematological malignancy patients with febrile neutropenia. Patients were divided into two groups according to the mean initial dose (MID) over the first 3 days of treatment: (i) MID = 533.33 mg/day (loading dose group, 400 mg q12h for three doses followed by 400 mg qd, n = 62) and (ii) MID < 533.33 mg/day (unloaded or underloaded group, n = 52). During the first 3 days after treatment, the overall Cmin was higher in group 1 than in group 2 (10.96 ± 5.44 mg/L versus 6.31 ± 3.73 mg/L, mean ± S.D.; p = 0.002), as was the qualifying rate of Cmin > 10 mg/L (54.5% versus 11.1%, p = 0.001), and the probability of Cmin < 5 mg/L was lower in group 1 than in group 2 (13.6% versus 40.7%, p = 0.037). After 3 days, the average Cmin and qualifying rates did not differ significantly between the two groups, and the average Cmin was <10 mg/L in both groups. Binary logistic regression analysis revealed that creatinine clearance (p = 0.004) and MID (p = 0.010) could affect Cmin during the first 3 days of treatment and that age (p = 0.022) only could affect Cmin after 3 days. In conclusion, it is necessary to apply loading dose to achieve teicoplanin Cmin > 10 mg/L rapidly and, from a pharmacokinetic/pharmacodynamic perspective, 600 mg is recommended as loading and maintenance dose for these patients when AUC24 /minimum inhibitory concentration > 345.

Abstract
In the treatment of severe MRSA infections such as endocarditis, more than 20 mg/L of plasma trough concentration (C(min)) is recommended for teicoplanin; however, in the treatment of common MRSA infections, recommended C(min) remains more than 10 mg/L. In this study, we set C(min) as 15-30 mg/L to obtain a favorable clinical outcome in the treatment of common MRSA infections, and investigated the optimal loading regimen that achieved the target C(min) in patients with normal renal function. Seventy-eight patients received the high-dose regimen A (6 mg/kg every 12-h for initial two days) and 60 patients received the high-dose regimen B (the first five loading doses of 10-12 mg/kg at 12-h intervals for initial three days, followed by 6 mg/kg once daily). The mean C(min) on the 4th day was 13.7 ± 5.3 mg/L in regimen A, and 20.0 ± 6.6 mg/L in regimen B (P < 0.001), and the proportion of patients achieving the 15-30 mg/L was 25.6% and 68.3% (P < 0.001). Clinical response at end-of treatment were 66.7% and 85.0% (P = 0.014). The patients of initial C(min) with ≥15 mg/L had tended to be higher clinical response than those with <15 mg/L (80.9% vs 68.6%, P = 0.084). There were no significant differences in the occurrence of adverse effects in regimen A and B (nephrotoxicity; 1.3% vs 3.3%, P = 0.413, hepatotoxicity; 5.1% vs 3.3%, P = 0.608). In conclusion, to obtain C(min) 15-30 mg/L, the first five loading doses of 10-12 mg/kg at 12-h intervals was required in patients with normal renal function.

Abstract
Background The present study was designed to investigate whether teicoplanin minimum inhibitory concentrations (MICs) of methicillin-resistant Staphylococcus aureus (MRSA) isolates play a role in the prognosis of patient with teicoplanin-treated MRSA bloodstream infection (BSI). Methods Between 1 January 2006 and 31 December 2009, adult patients with teicoplanin-treated MRSA BSI in two Taiwan medical centers were retrospectively enrolled. Their blood MRSA isolates were submitted for determination of MICs to various antibiotics and multi-locus sequence types. All-cause mortalities on Days 14 and 30, as well as clinical response at the end of teicoplanin therapy were treated as endpoints. Results Two hundred seventy adult patients were enrolled and 210 blood MRSA isolates were available. Independent risk factors for un-favorable outcome at the end of teicoplanin therapy included septic shock (p < 0.0001) and an elevated C-reactive protein level (p = 0.0064). The independent risk factors for all-cause Day 14 mortality (13.0%) included the presence of auto-immune diseases (p = 0.0235), septic shock (p = 0.0253) and thrombocytopenia (p = 0.0018). The independent risk factors for all-cause Day 30 mortality (26.3%) included age (p = 0.0102), septic shock (p < 0.0001) and thrombocytopenia (p = 0.0059). Conclusions The current study didn’t find a significant role for teicoplanin MICs in the prognosis of adult patients with teicoplanin-treated MRSA BSI.

Abstract
BACKGROUND A trough concentration of >20 mg/L is considered the optimal dosage of teicoplanin required to ensure early therapeutic effects against methicillin-resistant Staphylococcus aureus (MRSA) infections including those in patients who develop febrile neutropenia after chemotherapy. This study determines appropriate initial doses during the first 2 days of administration and evaluates the therapeutic target teicoplanin trough concentration. METHOD A 2-day regimen was evaluated in patients treated with 600 mg and 1200 mg or 1200 mg and 600 mg (total 1800 mg, Group 1), 800 mg and 800 mg (total 1600 mg, Group 2), and 800 mg and 400 mg (total 1200 mg, Group 3) of teicoplanin on Days 1 and 2, respectively. We also compared the efficiency and adverse effects at trough concentrations of 15-20 mg/L (Group A, n = 28) with >20 mg/L (Group B, n = 27) of teicoplanin, and also compared them with those on the similar concentrations of vancomycin (Groups C and D, n = 50 and 34, respectively). RESULTS The mean trough concentrations of teicoplanin on Days 4 or 5 were 22.2, 17.5, and 16.2 mg/L in Groups 1, 2, and 3, respectively. The clinical efficiency was 85.7%, 81.5%, 92.0%, and 91.5%, in Groups A, B, C, and D, respectively. The rates of adverse effects were not high in teicoplanin (nephrotoxicity, 7.1% and 3.7%, and hepatotoxicity, 14.3% and 11.1% in Groups A and B, respectively). However, more adverse effects tended to arise in patients who received vancomycin in nephrotoxicity (14.0% and 11.8%, in Groups C and D, respectively). CONCLUSION These results suggest that the 2-day regimens with total 1800 mg achieved the most effective therapeutic trough plasma concentration of teicoplanin (20 mg/L). However, 15-20 mg/L might also be an effective trough target for initial teicoplanin treatment. These teicoplanin regimens might be safer in terms of renal function than vancomycin.

Relationship of teicoplanin MICs to treatment failure in teicoplanin-treated patients with methicillin-resistant Staphylococcus aureus pneumonia. JOURNAL OF MICROBIOLOGY, IMMUNOLOGY, AND INFECTION = WEI MIAN YU GAN RAN ZA ZHI 2012; 46:210-6. [PMID: 22999099 DOI: 10.1016/j.jmii.2012.06.010] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/09/2012] [Revised: 06/14/2012] [Accepted: 06/28/2012] [Indexed: 02/06/2023]
Abstract
BACKGROUND/PURPOSE The objective of this study was to determine the predictive value of teicoplanin minimal inhibitory concentrations (MICs) for treatment failure among patients with methicillin-resistant Staphylococcus aureus (MRSA) pneumonia. METHODS In this study, all patients with ≥1 tracheal aspirates or sputum cultures positive for MRSA admitted to the hospital between April 2011 and September 2011 were reviewed. We enrolled patients who are ≥18 years of age, with a diagnosis of pneumonia, and with a receipt of teicoplanin therapy throughout the course. The relationship between teicoplanin Etest MICs and treatment outcomes of MRSA pneumonia was analyzed to identify the breakpoint of teicoplanin MICs influencing treatment outcomes. RESULTS Of the 80 patients enrolled, 31 had a lower teicoplanin MIC level (<2.0 mg/L) and 49 had a higher MIC level (≥2.0 mg/L) for MRSA. The lower MIC group had a higher clinical resolution rate in 14 days [24 (77.4%) vs. 23 (46.9%), p = 0.007] and a lower treatment failure rate at the end of teicoplanin treatment [4 (12.9%) vs. 18 (36.7%), p = 0.020]. A comparison between the treatment success and failure groups showed that the former had a longer duration of teicoplanin use (18.76 ± 10.34vs.12.41 ± 5.65 days; p = 0.014). Results of a multivariate analysis showed that teicoplanin MICs ≥ 2.0 mg/Land shorter duration of teicoplanin therapy were independent risk factors for treatment failure. CONCLUSION A higher teicoplanin MIC value (≥2.0 mg/L) may predict the treatment failure among patients with teicoplanin-treated MRSA pneumonia.
