Summary
This study details a rare case of isolated adrenocorticotropic hormone (ACTH) deficiency presenting with hypercalcaemia. This finding is unusual as hypercalcaemia is not a typical symptom of ACTH deficiency.
Area of Science:
- Endocrinology
- Internal Medicine
- Clinical Case Study
Background:
- Adrenocorticotropic hormone (ACTH) deficiency, or hypocortisolaemia, typically presents with symptoms like fatigue and weight loss.
- Hypercalcaemia is not a classically recognized feature of isolated ACTH deficiency, but is more commonly associated with conditions like Addison's disease.
Observation:
- A 76-year-old male patient presented with subacute weight loss, malaise, and anorexia.
- Progressive hypercalcaemia was observed, correlating with the patient's clinical decline.
- The patient's symptoms improved following intravenous steroid administration, indicating hypocortisolaemia.
Findings:
- Biochemical testing confirmed isolated ACTH deficiency as the underlying endocrinopathy.
- The case highlights an atypical presentation of ACTH deficiency, characterized by significant hypercalcaemia.
- This contrasts with Addison's disease, where hypercalcaemia is a more common, though not universal, finding.
Implications:
- This case expands the known clinical spectrum of isolated ACTH deficiency.
- It underscores the importance of considering atypical presentations in diagnosing endocrine disorders.
- Further research may be warranted to elucidate the mechanisms linking ACTH deficiency and hypercalcaemia.

01:17Hormones and Bone Tissue
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

01:21Skeleton and Calcium Homeostasis
Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.
00:51Synthesis and Functions of Calcitonin
Calcitonin, a vital polypeptide hormone, regulates calcium levels within body fluids. It is released by the parafollicular cells, also known as C cells, situated in the follicular epithelium of the thyroid gland. Calcitonin responds to fluctuations in blood calcium levels and the influence of gastrointestinal hormones like gastrin and cholecystokinin.
The exact mechanisms by which calcitonin operates in calcium homeostasis remain elusive, but its significance is evident in several vital...

01:24Graves Disease II: Pathophysiology
Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor, and heat...
01:26Cushing Syndrome I: Introduction
Cushing syndrome refers to the collection of clinical manifestations that arise when tissues are exposed to excessive amounts of cortisol or cortisol-like medications over an extended period. Cortisol, a glucocorticoid produced by the adrenal cortex, regulates metabolism, immune responses, and the body’s adaptation to stress. When its concentration remains chronically elevated, these physiological pathways become dysregulated, resulting in the characteristic features of the syndrome.Exogenous...
01:19Cushing Syndrome II: Pathophysiology
Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features of the...
