Vancomycin and Cefoxitin During Pediatric Cardiopulmonary Bypass (VANCOCEF)

January 13, 2020 updated by: Zaccaria Ricci, Bambino Gesù Hospital and Research Institute

Vancomycin and Cefoxitin Levels During Pediatric Cardiac Surgery With Cardiopulmonary Bypass

The aim of this study will be to evaluate vancomycin and cefoxitin blood levels during elective cardiopulmonary bypass (CPB) surgery in four pre-determined pediatric strata: neonates, infants, children weighting less than 40 kg and children weighting more than 40 kg.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Few data are available in current literature about pharmacokinetics (PK) of antibiotics administered as surgical prophylaxis to children scheduled for cardiac surgery with CPB. In particular, vancomycin PK during CPB has been studied only in small case series, whereas no specific study has been conducted, so far, in the specific setting of children receiving cefoxitin during CPB.

CPB affects patients' volemia and drugs PK is eventually altered. On the other side during and after surgery for heart defects, many risk factors may decrease renal and hepatic clearance, including altered renal perfusion, use of vasoactive agents, and use of concomitant nephrotoxic medications.

Primary Objective of the study will be:

• To study the pharmacokinetic profile of vancomycin and cefoxitin administered, as antibiotic prophylaxis to children undergoing elective CPB.

Secondary Objectives will be:

  • To evaluate if a significant difference in blood levels will occur in the four predetermined patients' categories.
  • To evaluate the role of hemodilution during CPB on studied antibiotics' serum concentration
  • To verify the incidence of post-operative infections in the studied population with particular attention to sensitive bacteria
  • To evaluate the impact of ultrafiltration in studied antibiotics' clearance
  • To evaluate safety of the administered antibiotics This is a prospective monocentric, open label, not controlled clinical trial.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

1 day to 18 years (ADULT, CHILD)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Children undergoing cardiac surgery requiring cardiopulmonary bypass and antibiotic prophylaxis with vancomycin and cefoxitin

Description

Inclusion Criteria:

  1. Elective cardiac surgery schedule with the planned application of CPB
  2. Parents of neonates, or their legal representative, able to consent and comply with protocol requirements.

Exclusion Criteria:

  1. Urgent or emergent surgery
  2. Antibiotic therapy (any) administered before surgery
  3. Patients receiving, before surgery, any other ofr of extracorporeal treatment (i.e extracorporeal membrane oxygenation, continuous renal replacement therapy)
  4. Previous renal or hepatic dysfunction requiring need for antibiotic posology modification.
  5. Surgery requiring antibiotic prophylaxis with different drug combinations (i.e vancomycin and gentamycin)
  6. extremely low birth weight neonates.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
vancomycin and cefoxitin pharmacokinetics
This is surgical prophylaxis and cefoxitin/vancomycin have to be administered to each patient of the study, before surgery
Other: vancomycin pharmacokinetics
vancomycin serial plasmatic and ultrafiltrate samples in order to assess plasmatic and ultrafiltrate drug concentrations
Other: cefoxitin pharmacokinetics
cefoxitin serial plasmatic and ultrafiltrate samples in order to assess plasmatic and ultrafiltrate drug concentrations

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
vancomycin and cefoxitin concentration change in serial plasmatic samples
Time Frame: samples will be withdrawn: at skin incision, 15 minutes after CPB start (CPB1), at the end of CPB (CPB2), at end of surgery.
a 4-points pharmacokinetic curve per each antibiotic will be generated by serial average plasmatic vancomycin and cefoxitin concentration assessments.
samples will be withdrawn: at skin incision, 15 minutes after CPB start (CPB1), at the end of CPB (CPB2), at end of surgery.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
differences between pre-determined subgroups (neonates, infants, children weighting less than 40 kg and children weighting more than 40 kg) in plasmatic vancomycin and cefoxitin levels change at each time point
Time Frame: samples will be withdrawn: at skin incision, 15 minutes after CPB start (CPB1), at the end of CPB (CPB2).
samples will be withdrawn: at skin incision, 15 minutes after CPB start (CPB1), at the end of CPB (CPB2).
vancomycin and cefoxitin clearance by ultrafiltration
Time Frame: Ultrafiltrate sample will be withdrawn at the end of CPB (UF1)
The clearance of vancomycin and cefoxitin in the ultrafiltrate (UF) will be evaluated. Antibiotics' sieving coefficient (SC) will be calculated from antibiotics concentrations at the following time points: UF1/[(CPB1+CPB2)/2]. Antibiotics clearance will be calculated as SC*UF rate (ml/min)
Ultrafiltrate sample will be withdrawn at the end of CPB (UF1)
