How to monitor cyclosporine levels?
The following guidelines are recommended for laboratory monitoring of circulating levels of cyclosporine in dermatology patients. Measurements should be determined as trough levels in whole blood, not plasma or serum. The measurements should be performed with an assay that is specific for the parent cyclosporine compound (e.g., a high-performance liquid chromatography method or a specific monoclonal immunoassay). The results of nonspecific immunoassays that detect cyclosporine as well as its metabolites are difficult to interpret and cannot readily be compared among different studies or laboratories. In psoriasis patients, the circulating concentration of cyclosporine does not correlate reliably with the therapeutic response. Some patients may achieve an excellent response with blood levels in the range of 50 ng/ml; others may show little or no response despite blood levels as high as 200 ng/ml. In patients with a poor clinical response, monitoring of cyclosporine levels may be useful to confirm that the drug has been taken and may provide an estimate of the degree of absorption and metabolism of the parent compound. Because an upper limit of safety for the circulating concentration of cyclosporine has not been clearly defined, one should attempt to achieve a therapeutic response with the lowest possible dose. Clinicians must carefully monitor patients for signs of cyclosporine toxicity, regardless of the circulating concentration of the drug. Whole blood levels exceeding 250 ng/ml should be avoided.
Why is cyclosporine monitoring important?
In patients with a poor clinical response, monitoring of cyclosporine levels may be useful to confirm that the drug has been taken and may provide an estimate of the degree of absorption and metabolism of the parent compound.
Can cyclosporine be detected in immunoassays?
The results of nonspecific immunoassays that detect cyclosporine as well as its metabolites are difficult to interpret and cannot readily be compared among different studies or laboratories. In psoriasis patients, the circulating concentration of cyclosporine does not correlate reliably with the therapeutic response.
How long does it take for a syringe to stabilize?

How long after CsA dose can you collect blood?
By collecting serial blood samples over this limited period (4hr after the dose) and estimating the AUC0-4, one can gain insight into how well CsA has been absorbed for each transplant recipient, and individualise CsA dosage. However, a recent survey of Australasian CsA laboratories revealed that such AUC0-4sampling strategies in the early post-dose period were poorly accepted in clinics across Australasia. The alternative that has proven to be more clinically acceptable is the use of a single sample 2-hours after the dose (C2). The C2 concentration has been demonstrated (particularly in kidney and liver transplant recipients) as correlating well with AUC0-4, allowing it to be used as a surrogate index of CsA absorption and exposure.
What is the bioavailability of Csa?
In this way we can accommodate, at least partially, the generally poor and variable rate and extent of absorption (bioavailability) of CsA both inter- and intra-patient. On average, only about 40% of CsA in the oral dose survives the barriers to absorption and first-pass metabolism, in the gut-wall and liver to reach the systemic circulation, from where it reaches the tissues to exert its actions.1–3Perhaps a better term for CsA would be "critical concentration drug", as the dosage schedule is typically adjusted up or down so as to attain the desired target blood CsA concentration, in the light of the patient's clinical indices. This variability with the dosage/concentration relationship of CsA is shared with other immunosuppressant drugs currently used in organ transplantation, including tacrolimus, sirolimus and mycophenolic acid, as well as newer drugs currently in clinical trials, (eg. FTY-720 and everolimus) as recently reviewed.4–6
What is the temperature dependent equilibrium between plasma and red blood cells?
there was a significant temperature-dependent equilibrium between plasma and red blood cells such that each 1°C reduction in the temperature that plasma was separated from the cellular fraction caused a 14 μg/L reduction in plasma CsA concentration, making it difficult to obtain representative plasma CsA concentrations that reflected in vivocirculating concentrations (ie. at 37°C),
Why is heparin anticoagulated blood variable?
heparin anti-coagulated blood showed variable results due to the presence of micro-clots causing significant inconsistencies in the fraction sampled for assay in the laboratory.
Is C2 better than C0?
Further arguments and recommendations favouring C2 monitoring are reviewed elsewhere, including the recent consensus papers from the CONCERT group, and our Australasian group, as well as other reviews and recommendations.5,33,38–40,48,59–63They have all supported the use of C2 strategies as a more useful tool than C0 for CsA monitoring. However, like many issues regarding CsA over the years, there is also a (minority) counter argument, including one extensive review that concluded: "C0 is currently the standard method of monitoring CsA therapy and there is no evidence demonstrating the superiority of any other method of monitoring CsA over C0 in terms of patient outcomes”.54Another lung transplant study concluded: “monitoring either the C2 or C6 concentration did not give a better indication of response to CsA therapy in patients with lung transplants compared with C0”.64
Is C2 a peak or a concentration?
Whilst some authors have referred to the C2 sample as the 'peak' or Cmax concentration, it is probably inappropriate to link such terms with C2.55,56Even with the more predictable Neoral®formulation, the CsA absorption profile is quite variable and so the actual peak concentration may frequently occur before or well after two hours for many reasons.41, 42Rather, it is important to simply think of C2 as an index, or surrogate marker, of AUC0-4which is in turn a marker of CsA absorption.
Can CSA be measured using HPLC?
Whilst CsA can be measured using chromatographic approaches [HPLC/UV or LCMS(MS)], these have proved unpopular internationally, with <5% of laboratories in the International CsA Proficiency Testing Program (www.bioanalytics.co.uk) employing them. In Australasia, HPLC is used by only one laboratory which also has the largest CsA service in the region. The vast majority of laboratories use one of the commercial CsA immunoassays (Figure 1and Table 2).19
Why is it important to test cyclosporine levels?
Testing cyclosporine levels in the blood can help ensure that drug levels are in a range that will be therapeutic. If the level is too low, organ rejection may occur (in the case of transplantation) or symptoms may reappear (autoimmune cases). It is also important to ensure that the level is not too high and will not result in toxicity.
How long can you stay on cyclosporine?
It is not advised that your stay on cyclosporine for more than a year due to an increase in the likelihood of toxic symptoms the longer you are on the medication. Short-term or intermittent courses of 12 weeks at a time are more advisable.
Why do you need a cyclosporine test?
Tests for cyclosporine are used to measure the amount of this drug in the blood to determine whether cyclosporine concentrations have reached therapeutic levels and are not in a toxic range. Cyclosporine is a drug that diminishes the body’s immune response. It is prescribed for organ transplant recipients to prevent organ rejection and for some people with autoimmune conditions, such as rheumatoid arthritis or psoriasis, to alleviate symptoms.
What is cyclosporine used for?
Cyclosporine is an immunosuppressant drug used to reduce the body’s natural defenses. This test measures the amount of cyclosporine in the blood.
How long after cyclosporine is tested?
A majority of laboratories use whole blood samples for cyclosporine testing instead of serum or plasma and will collect samples 12 hours after the last dose or just before the next dose (trough levels).
How long after a transplant can you test for cyclosporine?
High levels of cyclosporine in peak samples are correlated with reduced rejection rates, especially in the first year after transplant surgery.
Does cyclosporine help with a transplant?
When people undergo an organ transplant, their immune system recognizes the graft as “foreign” and will begin to attack it just as it would any invasive bacteria or virus. Cyclosporine diminishes the ability of certain white blood cells in the immune system to respond to this foreign tissue. The transplanted organ then has a better chance of survival and will not be as easily rejected by the transplant recipient’s immune system. Cyclosporine is used routinely in the transplantation of kidney, heart, liver, and other organs.
