70% Ethanol for Decontamination of CVL Exposed to Calcineurine Inhibitors Version 1.0, 1/9/2014 (70% EtOH)

January 28, 2016 updated by: Rajinder Bajwa, Nationwide Children's Hospital
This is for a study for patients that will be undergoing hematopoietic stem cell transplant (HSCT). For HSCT, patients will need a double lumen central venous line (CVL). One of the most common complications after an HSCT is Graft Versus Host Disease (GVHD).Tacrolimus or Cyclosporine along with methotrexate are used together in order to prevent GVHD. Normally these medications are given via the white lumen and blood is drawn via the unexposed red lumen to check the blood level of these medications. If these drugs are accidentally given via the wrong lumen (line) it could cause blood levels to be falsely high. This error could lead to the patient having to have peripheral blood draws that cause pain. The investigators are proposing adding an ethanol lock to your lumens (lines) to see if this would help clean the lines therefore preventing errors in blood tests and blood draws. An ethanol lock is a 70% alcohol which is injected into the CVL lumen and stays within the CVL as the CVL is capped.

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

As cyclosporine and tacrolimus are both oil based medications and ethanol (70% alcohol) can dissolve oil, the investigators hypothesize that an alcohol lock instilled into the lumen of the CVL will be able to dissolve and leach out the oil based CNI adhering to the inside lumen of the CVL catheter, thus decontaminating it. The safety of using ethanol via CVL is already proven over the last many years. A study performed with neonates resulted in no adverse effects when using ethanol locks, proving that their use is safe for the pediatric population. Ethanol has been used as locks for disinfecting CVLs infected with a broad range of microorganisms in pediatrics. It has also been useful in treating catheter occlusions caused by Lipid formation. By placing a 70% ethanol lock for two hours in the contaminated lumen, it has shown to degrade the biofilm and fat formation allowing for further use of the CVL used 70 % ethanol locks and did not find any reductions in mechanical integrity of polyetherurethane or silicone catheters exposed for as long as 10 weeks. Also, no structural integrity complications have been found in the literature along with no evidence of systemic toxicity with the use of ethanol locks. A retrospective study on PICU patients who had received ethanol locks for 12-24 hours per lumen and a repeat lock when venous access was not limited, flushed 0.2-1mls of ethanol through the catheter at the end of the dwell instead of withdrawing the lock. Sixteen patients who received five daily ethanol lock treatments in succession, had liver enzymes measured and only two patients had mildly elevated transaminases, but these levels were not significant from their baseline levels. There were also no reports from the nurses of any patient complaints or side effects. The study stated that when larger volumes in which they classified as 2.3mls of ethanol are flushed through the central line, patients have reported flushing, light-headedness, headache, nausea and dyspnea. Only 2mls of ethanol will be administered in this study, and the ethanol lock will be withdrawn prior to drawing the levels. Therefore, no side effects are expected.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

3 months to 30 years (Child, Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Description

Inclusion Criteria:

  • All patients' ages 3 months to 30 years will be eligible for the study.

Experimental: 70% Ethanol
The study will use 70% ethanol lock in the CVLs. A 2ml 70% ethanol lock will be instilled into the white lumen of the CVL for 2 hours. At the end of 2 hours, the ethanol will be withdrawn; the CVL lumen flushed with normal saline, and the CVL would be available for normal use for that day.
Other: 70% Ethanol
the study will use 70% ethanol lock in the CVLs. A 2ml 70% ethanol lock will be instilled into the white lumen of the CVL for 2 hours. At the end of 2 hours, the ethanol will be withdrawn; the CVL lumen flushed with normal saline, and the CVL would be available for normal use for that day.

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
Primary Outcome: Serum Levels
Time Frame: 18 months
Serum levels from both lumens will be compared after 2-hour ethanol lock placements. If the mean serum levels drawn at 8pm from both lumens are equivalent, the intervention will be considered effective.
