E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Contrast variability of steroid profile during at least periods of time of two months versus the model developed from 2 days based model. Follow development of mathematical model implemented to characterized steroid profile during long periods of time. |
Contrastar variabilidad del perfil esteroideo en periodo 2 meses frente a 2 días consecutivos. Desarrollo de modelo matemático válido para caracterizar perfil esteroideo en periodos de tiempo largos. |
|
E.2.2 | Secondary objectives of the trial |
Characterize modification of steroid profile when testosterone is administered. Develop an analytical method that based on the use of GC-MS/MS permits to decrease uncertainty for quantification of samples with low concentration. Determine the parameters of the steroid profile taht will be more stables and sensitive against the exogenous administration fo steroids of endogenous steroids. Study the genetic influence over the steroid profile when an administration take place. Evaluate the efficiency of the CIRMS analysis for the selected population, influence of the genetic factor. Compare the efficiency of CIRMS analysis and the mathematical model. Identify new metabolites that could be less affected for the deletion. |
Caracterizar alteración de perfil esteroideo si se administra Testosterona Validar procedimiento de análisis que permita minimizar la imprecision en la estimación del perfil esteroideo en casos con concentraciones bajas, 10ng/mL o inferiores. Determinar el perfil esteroideo que sea más estables y sensible a la administración exógena de esteroides. Estudiar el comportamiento de las variables del perfil esteroideo en función del polimorfismo de UGT2B17. Evaluar la eficacia del análisis CIRMS en función del genotipo Contrastar la eficacia del análisis CIRMS con la eficacia del modelo matemático desarrollado. Identificar otros metabolitos de testosterona que no se vean alterados por la deleción pero sí por la administración exógena de esteroides anabolizantes. |
