Common variable immune deficiency, central diabetes insipidus, and anemia

Area of Science:

• Immunology
• Endocrinology
• Gastroenterology

Background:

• Common variable immune deficiency (CVID) is a primary immunodeficiency characterized by low immunoglobulin levels, leading to recurrent infections or inflammatory complications.
• Central diabetes insipidus (CDI) is a rare disorder of antidiuretic hormone regulation, potentially caused by autoantibodies.
• Celiac disease is an autoimmune enteropathy linked to other endocrine conditions.

Observation:

• A patient presented with a complex constellation of conditions including CVID, CDI, gluten-sensitive diarrhea, and anemia.
• The patient exhibited symptoms indicative of both immune dysregulation and endocrine dysfunction.

Findings:

• This case illustrates a rare co-occurrence of CVID, CDI, and celiac disease.
• The patient's anemia was identified as a combined type, involving thalassemia minor and vitamin B12 deficiency.

Implications:

• This case underscores the importance of considering diverse autoimmune and endocrine comorbidities in patients diagnosed with CVID.
• Recognizing these associations can lead to more comprehensive diagnostic approaches and improved patient management.
• Further research may elucidate shared pathophysiological mechanisms between CVID and certain autoimmune endocrinopathies.
