Primary Outcomes

Protein profile changes between physiological and supra physiological doses of betamethasone.

By using mas spectrometry, protein profile changes in blood, urine and saliva will be identified at four timepoints: after 3 hours and after 7 days during treatment with betamethasone in a physiological dose and after 3 hours and after 7 days during treatment with betamethasone in a supra physiological dose.

Time frame: Changes in proteome (g/dl or umol/l) during 7 days of treatment with two different doses of betamethasone

Metabolite profile changes between physiological and supra physiological doses of betamethasone.

By using mas spectrometry, metabolite profile changes in blood, urine and saliva will be identified at four timepoints: after 3 hours and after 7 days during treatment with betamethasone in a physiological dose and after 3 hours and after 7 days during treatment with betamethasone in a supra physiological dose.

Time frame: Changes in metabolome (units depending on the kind of metabolome) during 7 days of treatment with two different doses of betamethasone

Secondary Outcomes

Messenger RNA (mRNA)/miRNA profile changes between physiological and supra physiological doses of betamethasone.

By using array based transcriptomics (both mRNA and miRNA), mRNA/miRNA profile changes in blood, urine and saliva will be identified at four timepoints: after 3 hours and after 7 days during treatment with betamethasone in a physiological dose and after 3 hours and after 7 days during treatment with betamethasone in a supra physiological dose.

Changes in glucose metabolism between physiological and supra physiological doses of betamethasone.

Conventional markers for glucose metabolism in blood will be identified at four timepoints: after 3 hours and after 7 days during treatment with betamethasone in a physiological dose and after 3 hours and after 7 days during treatment with betamethasone in a supra physiological dose.

Time frame: Changes in glucose metabolism (units depending on sample analysis) during 7 days of treatment with two different doses of betamethasone

Changes in lipid-profile between physiological and supra physiological doses of betamethasone.

Conventional markers for lipid-profile in blood will be identified at four timepoints: after 3 hours and after 7 days during treatment with betamethasone in a physiological dose and after 3 hours and after 7 days during treatment with betamethasone in a supra physiological dose.

Time frame: Changes in lipid-profile (units depending on sample analysis) during 7 days of treatment with two different doses of betamethasone

Changes in bone-markers between physiological and supra physiological doses of betamethasone.

Bone-markers in blood will be identified at four timepoints: after 3 hours and after 7 days during treatment with betamethasone in a physiological dose and after 3 hours and after 7 days during treatment with betamethasone in a supra physiological dose.

Time frame: Changes in levels of bone-markers in blood (units depending on sample analysis) during 7 days of treatment with two different doses of betamethasone

Changes in self-reported Quality of Life between physiological and supra physiological doses of betamethasone using the Addison-specific Quality of Life questionnaire (ADDIQoL).

Self-reported health-related quality of life and general well-being will be assessed using the ADDIQoL questionnaire after 7 days of treatment with a physiological dose of betamethasone and after 7 days of treatment with a supra physiological dose of betamethasone.

Time frame: Changes in units of the ADDIQoL questionnaire (units on a scale) after 7 days of treatment with two different doses of betamethasone

Changes in self-reported Quality of Life between physiological and supra physiological doses of betamethasone using the Psychological General Well-being (PGWB) index.

Self-reported health-related quality of life and general well-being will be assessed using the PGWB index after 7 days of treatment with a physiological dose of betamethasone and after 7 days of treatment with a supra physiological dose of betamethasone.

Time frame: Changes in units of the PGWB index (units on a scale) after 7 days of treatment with two different doses of dexamethasone

Changes in self-reported quality of life and fatigue between physiological and supra physiological doses of betamethasone using the Fatigue impact scale (FIS)

Self-reported health-related quality of Life, general well-being and fatigue will be assessed using the FIS questionnaire after 7 days of treatment with a physiological dose of betamethasone and after 7 days of treatment with a supra physiological dose of betamethasone.

Time frame: Changes in units in the FIS (units on a scale) after 7 days of treatment with two different doses of betamethasone
