Introduction: Endogenous Cushing’s syndrome (CS) is a rare, infradiagnosed and severe disease that carries high morbidity and mortality. Delays in treatment initiation reduce reversibility of symptoms and increase mortality rate. Current gold standard for screening, 24 h urinary free cortisol, has a low reproducibility and specificity, and sampling is complicated. Midnight salivary cortisol (MSVC) determination is considered an easy and cheap test. We intend to assess its feasibility combined with suppression test to screen CS. This initiative has been developed by the Cushing’s disease (CD) working group, member of the Sociedad Española de Endocrinología y Nutrición (SEEN) and supported by Novartis.

Methods/design: Epidemiological cross-sectional study to asses MSVC plus suppression test. Secondary objectives are to describe the prevalence of CS and CD in the studied population. Patients will be performed the two tests, results from both, clinical characteristics and final diagnosis of CS or CD will be recorded.

Results: This project, named CRIbado en SALIva De Alteraciones del cortisol (CRISÁLIDA) was initiated on November 2012, with 13 participating sites accross Spain. Sample size will be 609 patients and results from an interim analysis are expected on April 2013. Study population includes a group of patients considered at risk of presenting high cortisol levels, presenting at least 2 of the following symptoms: obesity (BMI >30), hard to control hypertension (SBP >140 and DBP >90 mmHg, >2 drugs), poorly controlled diabetes (HbA1c >7.0%), severe osteoporosis (−2.5 S.D. in T-score) or virilization syndrome. Exclusion criteria: pregnancy, age >70 years, glucocorticoid treatment, CS or CD diagnosis, chronic renal impairment or hepatopathy, between others.

Conclusion: CRISÁLIDA is a multicentric project designed to identify most relevant characteristics of an at-risk population and to move forward in the screening and diagnosis of a rare disease (CD).
