Changes in complete blood count parameters influenced by endocrine disorders

Area of Science:

• Endocrinology
• Hematology
• Internal Medicine

Background:

• Hormonal status significantly influences complete blood count (CBC) parameters.
• CBC is a widely used diagnostic tool in clinical practice.
• Endocrine disorders can manifest with distinct alterations in blood cell counts.

Purpose of the Study:

• To review and summarize CBC changes indicative of endocrine disorders.
• To highlight the utility of CBC in diagnosing and monitoring hormonal imbalances.
• To correlate specific blood count abnormalities with various endocrine conditions.

Main Methods:

• Literature review of studies investigating CBC parameters in endocrine disorders.
• Analysis of reported changes in red blood cell, white blood cell, and platelet counts.
• Correlation of findings with specific endocrine conditions such as thyroid disorders, Cushing's disease, hypopituitarism, and polycystic ovary syndrome.

Main Results:

• Thyroid disorders are associated with red cell parameter changes, including normocytic, macrocytic, and microcytic anemias.
• Cushing's disease may present with elevated white blood cells and platelets, while hypopituitarism shows decreased red cell counts and platelets.
• Testosterone deficiency leads to reduced red cell parameters, whereas hyperandrogenism can cause polycythemia; polycystic ovary syndrome is linked to increased white blood cells.

Conclusions:

• Complete blood count is a valuable, accessible, and cost-effective tool for the initial diagnosis and ongoing management of endocrine disorders.
• Specific CBC patterns can guide the investigation and monitoring of various hormonal imbalances.
• Understanding these hematological manifestations aids clinicians in identifying and managing endocrine dysfunction effectively.
