📍Cushing’s Disease (Itzenko–Cushing syndrome due to pituitary origin) is a serious endocrine disorder caused by chronic exposure to elevated levels of cortisol. In most cases, it results from an ACTH-secreting pituitary adenoma, which overstimulates the adrenal glands to produce excessive cortisol. This leads to a wide range of metabolic, cardiovascular, and immunologic disturbances. The condition is more common in women and typically presents between the ages of 20 and 50.👆Main Symptoms:🔹Progressive weight gain, especially central obesity with thin arms and legs;🔹“Moon face” and “buffalo hump” due to fat redistribution;🔹Purple, wide striae on the abdomen, thighs, or breasts;🔹Muscle weakness, particularly of the proximal muscles;🔹Hypertension and glucose intolerance or diabetes;🔹Thin, fragile skin with easy bruising and slow wound healing;🔹Menstrual irregularities and decreased fertility in women;🔹Mood changes, including irritability, depression, or cognitive difficulties.🩸 Diagnosis:Diagnosis requires confirming cortisol excess and identifying its source. Common investigations include:🔹Elevated serum cortisol or loss of normal diurnal cortisol rhythm;🔹Abnormal results in low-dose dexamethasone suppression test;🔹Increased ACTH levels in pituitary-dependent disease;🔹MRI of the pituitary gland to detect adenomas;🔹Additional tests such as high-dose dexamethasone suppression or inferior petrosal sinus sampling when imaging is inconclusive.Treatment:The main goal is to normalize cortisol levels and remove the source of excess production. Standard treatment approaches include:🔹Transsphenoidal surgery to remove the ACTH-secreting pituitary adenoma — first-line therapy;🔹Medications that suppress cortisol synthesis (e.g., ketoconazole, metyrapone, osilodrostat) or block its effects;🔹Radiation therapy to the pituitary gland if surgery is incomplete or not possible;🔹Bilateral adrenalectomy in severe or refractory cases, with lifelong hormone replacement afterward;🔹Regular follow-up to monitor cortisol levels, metabolic complications, and recurrence.❗️Important:Cushing’s disease is a potentially life-threatening condition if untreated, increasing the risk of cardiovascular disease, infections, and metabolic disorders. Early diagnosis and timely treatment significantly improve prognosis, reduce long-term complications, and help patients regain normal quality of life.
