[Isolated ACTH deficiency associated with leukoneutropenia (author's transl)]

Summary
This study details a patient with isolated adrenocorticotropic hormone (ACTH) deficiency presenting with severe asthenia and persistent leuconeutropenia. Corticoid treatment improved symptoms, but leuconeutropenia persisted, suggesting additional factors beyond cortisol insufficiency.
Area of Science:
- Endocrinology
- Hematology
- Internal Medicine
Background:
- Adrenocorticotropic hormone (ACTH) deficiency can lead to hypocortisolism, impacting various bodily functions.
- Leuconeutropenia, a decrease in white blood cells, can have diverse underlying causes.
- The interplay between hormonal regulation and hematopoiesis is complex and warrants further investigation.
Observation:
- A 38-year-old male alcoholic presented with severe asthenia.
- Investigations revealed isolated ACTH deficiency with low plasma cortisol and ACTH levels, unresponsive to stimulation tests.
- Persistent leuconeutropenia was observed, with normal bone marrow and negative etiocholanolone test, but a positive response to epinephrine.
Findings:
- The patient exhibited isolated ACTH deficiency, confirmed by low cortisol and ACTH levels.
- Persistent leuconeutropenia was a significant finding, not fully explained by the cortisol deficiency alone.
- Corticoid replacement therapy partially improved the leuconeutropenia, indicating a potential secondary mechanism.
Implications:
- This case highlights that isolated ACTH deficiency can present with hematological abnormalities like leuconeutropenia.
- The partial response to corticoid treatment suggests that factors other than cortisol insufficiency may contribute to leuconeutropenia in such cases.
- Further research is needed to elucidate the complex relationship between ACTH deficiency, cortisol levels, and leucopoiesis.
