    This study on hypopituitarism in Black and Indian patients found tumors were a common cause. Growth hormone deficiency was most frequent, often alongside gonadotropin deficiency.

    Area of Science:

    • Endocrinology
    • Internal Medicine
    • Neuroendocrinology

    Background:

    • Hypopituitarism, a condition of reduced pituitary hormone secretion, can stem from various causes.
    • Tumors are a significant etiology of hypopituitarism, necessitating prompt diagnosis and management.
    • Understanding the demographic and clinical spectrum of hypopituitarism is crucial for effective patient care.

    Purpose of the Study:

    • To describe the clinical characteristics and hormonal deficiencies in a cohort of Black and Indian patients diagnosed with hypopituitarism.
    • To identify the primary causes and common presenting symptoms of hypopituitarism in this population.
    • To analyze the spectrum of hormonal insufficiencies, from single to multiple hormone deficiencies.

    Main Methods:

    • Retrospective analysis of 16 Black and Indian patients diagnosed with hypopituitarism over a 3-year period.

  • Review of patient demographics, presenting symptoms, underlying etiologies, and hormonal profiles.
  • Categorization of hormonal deficiencies, including monohypopituitarism and multiple hormone deficiencies.

    • Main Results:

    • Tumors were identified as the cause of hypopituitarism in 11 out of 16 patients.
    • Headaches and visual disturbances were the most common presenting symptoms, linked to the prevalence of tumors.
    • Growth hormone deficiency was the most frequent isolated deficiency, while combined growth hormone and gonadotropin deficiency was most common.
    • Hyperprolactinemia was observed in 4 patients.
    • The severity of hypopituitarism varied, ranging from single hormone deficiency to complete pituitary hormone failure.

    Conclusions:

    • Tumors are a leading cause of hypopituitarism in the studied Black and Indian population.
    • Clinical presentation often involves headaches and visual disturbances due to tumor mass effect.
    • Growth hormone and gonadotropin deficiencies are prevalent, highlighting the need for comprehensive hormonal assessment.
