Fundamento

Análisis de la actividad de la 11-β-hidroxiesteroide deshidrogenasa en el síndrome de Cushing.

Pacientes método

Determinación de la eli-minación en orina de 24 h de cortisol, corti-sona sus tetrahidroderivados en 15 pacientes con síndrome de Cushing 24 controles sanos.

Resultados

Existía una relación lineal significativa entre cortisol cortisona (r = 0,70; p < 0,0001) entre sus tetrahidroderivados (r = 0,75; p < 0,0001) en los controles, pero no en los pacientes.

Conclusiones

Los pacientes con síndrome de Cushing presentan un déficit de la actividad de la 11-β-hidroxiesteroide deshidro-genasa.

Background

To study 11 β-hydroxysteroid dehydrogenase activity in Cushing's syndro-me.

Patients and method

Measurements of free cortisol, cortisone, tetrahydrocortisol and tetrahydrocortisone in 24 h urine samples of patients with Cushing's syndrome and controls.

Results

The cortisol to cortisone and tetrahy-drocortisol to tetrahydrocortisone relationship was significant (in controls, r = 0.70; p < 0.0001, and r = 0.75; p < 0.0001) respectively, but it was not in patients with Cushing's syndrome.

Conclusions
