Diabetes insipidus associated with leukaemia

Area of Science:

• Hematology
• Endocrinology
• Oncology

Background:

• Leukemia, a cancer of blood-forming tissues, can present with diverse complications.
• Pituitary diabetes insipidus, characterized by excessive thirst and urination, can arise from various causes, including neoplastic infiltration.

Observation:

• This report details three cases where leukemia was complicated by pituitary diabetes insipidus.
• In one patient, pituitary diabetes insipidus manifested five months prior to the clinical diagnosis of acute myelomonocytic leukemia.
• The other two patients had acute myelomonocytic leukemia and blastic transformation of chronic myeloid leukemia, respectively.

Findings:

• The study highlights the association between specific types of leukemia and the development of pituitary diabetes insipidus.
• One patient experienced a transient resolution of diabetes insipidus following intrathecal chemotherapy and cranial irradiation.

Implications:

• These cases underscore the importance of recognizing pituitary diabetes insipidus as a potential paraneoplastic syndrome in leukemia patients.
• Early recognition and management of diabetes insipidus may be crucial for patient care during leukemia treatment.
• Further research is warranted to elucidate the mechanisms linking leukemia and pituitary dysfunction.
