Overview
Historical Perspective
- Sheehan syndrome was first discovered by Leon Konrad Gliński about a century ago and it was named after Harold Sheehan(1900-1988).[1][2]
Classification
- There is no established system for the classification of Sheehan's syndrome.
Pathophysiology
Causes
- Common causes of Sheehan's syndrome include massive hemorrhage, hypotension during pregnancy, vascular compression, and vascular occlusion(thrombosis, DIC). Less common causes include vascular insufficiency due to CABG in older patients and snake bites(Russell's viper bites).
Differentiating ((Page name)) from Other Diseases
- Sheehan syndrome must be differentiated from lymphocytic hypophysitis, pituitary apoplexy, hypothyroidism, Addison's disease, panhypopititarism, empty sella syndrome, hypogonadotropic hypogonadism, Simmond's disease, hypoprolactinemia, menopause,female athlete triadand SAH.[3][4][5]
Epidemiology and Demographics
- The incidence of Sheehan's syndrome is difficult to assess.[6] It was found to be the 6th most common cause of GH deficiency with an incidence of 3.1% of cases.[7] In 2009, the prevalence of Sheehan's syndrome was estimated to be 5.1 per 100,000 women.It is less prevalent in developed countries due to better obstetrical care and maternal health awraeness.[8][9].It is still one of the most common causes of hypopituitarism in developing countries.[9].
Risk Factors
- Common risk factors in the development of Sheehan's syndrome include pregnancy, severe/massive PPH, pituitary mass, pre-existing vascular diseases, autoimmunity,type 1 Diabetes, DIC, smaller and rigid sella, multiple gestations, placental abnormalities and traumatic delivery.
Screening
- There is insufficient evidence to recommend routine screening for Sheehan's syndrome.
Natural History, Complications, and Prognosis
- Sheehan's syndrome, if left untreated lead to hypopituitarism and empty sella syndrome.
- Common complications include adrenal crisis, hypotension, hypothyroidism and hypopituitarism.
- Prognosis is generally excellent provided early diagnosis and management resulting in complete reversal of symptoms.
Diagnosis
- Diagnosis is made on clinical basis with a recent/remote history of traumatic delivery or delivery complicated by hypotension.
Diagnostic Criteria
- Diagnosis is made on clinical basis with a recent/remote history of traumatic delivery or delivery complicated by hypotension.
- Diagnosis is mostly clinical but following steps are required to make the established diagnosis.
History and Symptoms
- The most common symptoms of Sheehan's sydrome include agalactorrhea and failure to resume menstruation after parturition. Common symptoms include hot flushes, decreased pubic/axillary hair, hypotension, hypoglycemia, features of hypothyroidism, hypoadrenalism and hypogonadism.
Physical Examination
- Patients with syndrome usually appear fatigued, lethargic and weight gain. Physical examination is usually remarkable for bradycardia, hypotension, pallor and signs suggestive of respective hormonal deficiency.
Laboratory Findings
- Laboratory findings consistent with the diagnosis of Sheehan's syndrome include hyponatremia, hypokalemia, hypocalcemia, hypomagnesemia, hypophosphatemia, anemia, pancytopenia, eosinophilia, hypoalbuminemia, low fasting plasma glucose etc.
Electrocardiogram
- ECG findings associated with Sheehan's syndrome can include QT interval prolongation,Type-1 Brugada-like ECG pattern(due to adrenal crisis),findings suggestive of cardiac tamponade, dilated cardiomyopathy(multifactorial).[12][13][14][15]
X-ray
- There are no x-ray findings associated with Sheehan's syndrome.
CT scan
- Acute presentation shows non-hemorrhagic pituitary gland enlargement while chronic presentation shows an empty sella or decreased sellar volume.[16][17][18]
