Plain Language Summary:
Background Glucocorticoids are stress hormones produced by the human body to control inflammation and regulate the immune system. Cortisol is the most well-known example of a glucocorticoid. These stress hormones are essential for the bodys healthy functioning.
To treat certain types of cancer, such as leukemia (blood cancer) in children, glucocorticoids are administered as medications in large quantities. This helps rapidly reduce the number of cancer cells in the body but also leads to the suppression of the body's natural glucocorticoid production, causing a deficiency.
This deficiency can be particularly dangerous for children with leukemia, as their immune defenses are already weakened by chemotherapy, leading to an increased risk of infections. Moreover, the signs of glucocorticoid deficiency in children with leukemia are often indistinguishable from the side effects of chemotherapy, making the deficiency harder to detect.
Objectives The aim of the study is to understand how frequently and for how long the body's natural glucocorticoid production is impaired in children treated for lymphoblastic leukemia and lymphoblastic lymphoma. Additionally, the goal is to identify which children are at particularly high risk.
By gaining a better understanding, this study may help to improve the detection and treatment of glucocorticoid deficiency in children with blood cancer.
Methods Regular low-dose ACTH tests will be conducted to assess the bodys natural glucocorticoid production during and after treatment. To avoid placing additional burden on children who are already heavily affected by the disease, these tests will only be performed when there is already a venous access established and the children are in the hospital for treatment reasons.

| Measure | Description | Time Frame |
|---|---|---|
| Occurence of Adrenal Insufficiency | The primary outcome of this study is he measurement of the occurrence of HPA axis suppression. The outcome is binary (yes/no) and is considered yes, if a HPA axis suppression occurs at 1 test or more. HPA axis suppression is commonly defined as stimulated cortisol levels below 500nmol/l (below 18μg/dl) in the low-dose ACTH stimulation test, i.e. a measurement of cortisol 30 minutes and 60 minutes after the stimulation with 1 μg of synthetical ACTH (Synacthen®). For further analyses the following subgroups may be considered: - Morning cortisol according to current norm values from our laboratory: suppressed if below 66nmol/l (1-11 years) / below 100nmol/l (12-18 years)
below 100nmol/l = suppressed, 100-200nmol/l = partially suppressed, above 200nmol/l = normal | Study enrollment until 3 months after the last dose of glucocorticoid treatment |
| Measure | Description | Time Frame |
|---|---|---|
| Duration of Adrenal Insufficiency | The measurement of the duration of HPA axis suppression. The outcome is continuous (in weeks). lf there is no occurrence of HPA axis suppression (primary outcome, then this secondary outcome is 0 weeks. The cut-off values are specified under the primary outcome section. | Study enrollment until 3 months after the last dose of glucocorticoid treatment |
| Measure | Description | Time Frame |
|---|---|---|
| Number of infections | Number of infections: According to medical record. An infection is suspected at a temperature of at least 38.5°C (measured in hospital). This is a continuous outcome (in numbers). | Study enrollment until 3 months after the last dose of glucocorticoid treatment |
| Total days of hospitalization |
Inclusion Criteria:
Exclusion Criteria:
- Contraindication to the administration of intravenous synthetical ACTH (Synacthen®): extremely rare cases of known or suspected hypersensitivity to Synacthen®.
