Switching from HPLC/UV to MEIA for whole blood sirolimus quantitation: comparison of methods.

Sirolimus is a immunosuppressive agent for renal transplant recipients. Monitoring of whole blood sirolimus concentration is necessary in order to improve clinical outcomes. An increasing number of clinical laboratories (4-14% during 2005) are using microparticle enzyme immunoassay (MEIA) for sirolimus quantitation but previous reports indicated a high variability, with a mean difference of 17% for MEIA method vs.

Prevalence of abuse of alcohol and other drugs among injured drivers presenting to the emergency department of the University Hospital of Modena, Italy.

Among those drivers responsible for injury-producing traffic crashes in a town of northern Italy (Modena) and its surrounding territory, we evaluated the percentage that was positive for alcohol or other drugs affecting CNS function. A total of 115 crash-responsible injured drivers (90 males and 25 females) consecutively presenting to the emergency department at the University Hospital of Modena were enrolled. A urine sample was requested from each driver; the presence of alcohol or drugs was detected by means of various procedures (enzyme immunoassay, liquid or gas chromatography, mass spectrometry).
