Endocrinopathies in Inborn Errors of Immunity.

Area of Science:

• Immunology
• Endocrinology
• Genetics

Background:

• Inborn errors of immunity (IEI) encompass over 400 genetic disorders affecting immune system function.
• The endocrine system is frequently impacted in IEI, influencing growth, reproduction, homeostasis, and energy regulation.
• Endocrine dysfunction in IEI commonly presents as hypofunction, necessitating timely intervention.

Purpose of the Study:

• To provide a comprehensive review of endocrine disorders associated with IEI.
• To elucidate the clinical features and pathophysiology of endocrinopathies in IEI.
• To discuss management strategies and long-term outcomes for affected individuals.

Main Methods:

• Literature review synthesizing current knowledge on IEI and endocrine dysfunction.
• Analysis of the two primary pathophysiological mechanisms: autoimmune responses and direct genetic effects.
• Detailed examination of specific endocrinopathies, including growth failure, hypothyroidism, hypoparathyroidism, adrenal insufficiency, and diabetes mellitus.

Main Results:

• Endocrine disorders in IEI arise from autoimmune processes or direct gene defects.
• Commonly affected endocrine systems include those regulating growth, thyroid function, calcium homeostasis, adrenal function, and glucose metabolism.
• Hematopoietic stem cell transplantation can also lead to endocrinopathies like hypogonadism and adrenal insufficiency.

Conclusions:

• Understanding the interplay between IEI and the endocrine system is vital for comprehensive patient care.
• Early diagnosis and appropriate management of endocrine complications in IEI are essential for improving patient outcomes.
• Further research into the specific mechanisms and tailored therapies for IEI-related endocrinopathies is warranted.
