A 25-year-old woman with severe diabetes mellitus since the age of 7 developed anterior pituitary insufficiency after pregnancy toxaemia with hypofunction of the thyroid, ovaries and adrenal cortex. Following the development of Sheehan's syndrome, her insulin requirment decreased dramatically. I.v. administration of TRH, LRH and vasopressin induced nearly normal pituitary response levels of TSH, LH and plasma cortisol, indicating a hypothalamic damage as the primary aetiological factor.

The neurohypophyseal function was assessed in a group of 15 patients with postpartum hypopituitarism by measuring plasma arginine-vasopressin concentrations during 5% hypertonic saline infusion. None of the patients had symptoms of diabetes insipidus and all patients were on adequate cortisone and thyroxine replacement therapy before testing. The mean basal plasma vasopressin value in the patients (0.6 +/- 0.1 pmol/l) was significantly lower than that in the normal subjects (2.9 +/- 0.3 pmol/l; p < 0.01), whereas the mean serum sodium, plasma osmolality, plasma renin activity and serum aldosterone values were similar in the two groups. During the osmolar load (5% hypertonic saline), the patients revealed varying degrees of arginine-vasopressin responses to the increase in plasma osmolality. Three patients showed normal arginine-vasopressin responses, 10 had subnormal responses, and 2 had no response. During the dehydration test, the patients revealed significantly lower maximum urine osmolalities (p < 0.0025) with significantly higher concurrent mean plasma osmolality (p < 0.0025) than the controls. None of the patients showed overt polyuria at the time of the study. The results indicate the impaired osmoregulation of arginine-vasopressin secretion to an osmolar stimuli in patients with postpartum hypopituitarism, suggesting neurohypophyseal damage. In patients with Sheehan's syndrome, partial diabetes insipidus seems to be much more frequent than previously believed.

A 27-year-old woman experienced hemorrhagic shock after delivery. One week later she was seen in an obtunded state of consciousness. The results of laboratory evaluation were consistent with the syndrome of inappropriate antidiuretic hormone secretion caused by hypopituitarism. Hydrocortisone rapidly corrected sodium levels. Syndrome of inappropriate secretion of antidiuretic hormone caused by Sheehan's syndrome should be considered in the differential diagnosis of postpartum hyponatremia.

We evaluated six patients in whom a diagnosis of Sheehan's syndrome had been made. The plasma levels of the following hormones were measured: basal thyroxine (T4), estradiol and cortisol; and also follicle-stimulating hormone (FSH), luteinizing hormone (LH), growth hormone (GH), thyrotropin (TSH), prolactin (PRL) and adrenocorticotropic hormone (ACTH), basally and after acute challenge with LH releasing hormone (LHRH), GRF (1-29)NH2 or insulin hypoglycemia, TSH releasing hormone (TRH) and lysine-8-vasopressin, respectively. Two patients underwent chronic LHRH stimulation by pulsatile subcutaneous administration with infusion pump. In 4 cases, computed tomography (CT) was performed although cranial X-ray study was normal. A severe and generalized pituitary involvement was found in all patients, 3 of whom had diabetes mellitus. Probably, more insidious cases go unnoticed. The presence of asymptomatic partial empty sella (ES) in all the CTs that were carried out raises the possibility that it is another evolutive feature of SS.

We studied neurohypophyseal function in 12 women with postpartum hypopituitarism (Sheehan's syndrome) by measuring plasma arginine vasopressin concentrations during 5% hypertonic saline infusions. All patients had a history of obstetric shock or massive bleeding, and were receiving cortisol and/or L-T4 replacement therapy. None had any symptoms of diabetes insipidus. The mean basal plasma vasopressin level in the patients [0.6 +/- 0.1 (+/- SE) pmol/L] was significantly lower (P less than 0.01) than that in normal adults (2.5 +/- 0.5 pmol/L; n = 12), whereas mean plasma osmolality values were similar in the two groups. During hypertonic saline infusion, the 10 hypopituitary patients had varying degrees of subnormal arginine vasopressin responses to the increase in plasma osmolality. Urine-concentrating ability after dehydration also was lower in the patients, although overt polyuria was absent at the time of this study. These results indicate that the osmoregulation of arginine vasopressin secretion is frequently impaired in postpartum hypopituitarism, suggesting neurohypophyseal damage.

A 22-year old woman in the 37th week of her third pregnancy (twins) developed acute fatty liver complicated with a haemorrhagic syndrome from disseminated intravascular coagulation. Two normal girls were delivered by caesarean section. Persistent surgical bleeding required hysterectomy and a short stay in an intensive care unit. The disseminated intravascular coagulation subsided within 8 days. Three weeks after delivery a pituitary insufficiency (Sheehan's syndrome) was diagnosed. A second liver biopsy showed that the lesions had regressed. One week after delivery, the patient developed polyuria and polydipsia. The diagnosis of diabetes insipidus was confirmed by the lack of increase of plasma antidiuretic hormone level during an 8-hour water deprivation test. The pathophysiology of these different syndromes is discussed. Disseminated intravascular coagulation might be the link between hypopituitarism and diabetes insipidus.

A case of a 69-year-old woman with postpartum hypopituitarism (Sheehan's syndrome) associated with congestive heart failure and severe hyponatremia is reported. She developed congestive heart failure after cholecystectomy, and marked improvement was noted by treatment with oxygen, digoxin, furosemide, and dopamine. Two weeks after surgery, she became confused, and hyponatremia, 106 mEq/l, was detected. She was referred to us. Past history revealed postpartum hemorrhage at the age of 34, followed by a failure to lactate, menoschesis, and loss of pubic hair and axillary hair. Hypertonic saline (1.5%) infusion and water restriction increased her serum sodium concentration into the low normal range. Despite hyponatremia, serum vasopressin was not suppressed. Basal levels of pituitary hormones were low, and they did not respond to provocation tests. Marked impairment of water excretion was noted, and plasma vasopressin was not suppressed during a water-loading test. These results suggest that inappropriately increased vasopressin played an important role in impaired water excretion, and this defect could have been responsible for the development of hyponatremia and congestive heart failure in this patient.

Sheehan's syndrome and diabetes insipidus were diagnosed in a 31-year-old woman seven months after postpartum bleeding with a short duration of hypotension. The diagnosis of diabetes insipidus was established by the inability to concentrate urine during water deprivation and the marked increase in urinary osmolality after administration of 1-Desamino-8-D-arginine-vasopressin (DDAVP). Obstetricians should be aware of diabetes insipidus as a postpartum complication.

Deficiencies of corticotrophin (ACTH), growth hormone, and prolactin were documented in a woman with diabetes mellitus and Sheehan's syndrome. The patient's ACTH deficit appeared to be secondary to a hypothalamic abnormality since on two occasions the patient had a marked plasma ACTH response to vasopressin but not to insulin induced hypoglycaemia. It is postulated that the deficits of these three adenohypophysial hormones were instrumental in causing a severely impaired aldosterone secretory capacity in response to sodium restriction and an angiotensin infusion. In addition, the patient had an unusual form of thyroid dysfunction that was in part reversed with hydrocortisone replacement. The patient's unfortunate death during a hypoglycaemic crisis allowed correlation between her extensive antemortum endocrine testing and her pathologic anatomy.

In a 20-year-old woman, a complicated full-term delivery was followed by a 14-month history of galactorrhea, amenorrhea, and symptoms of hypocortisolism. Evaluation revealed the presence of an empty sella, hyperprolactinemia, and an isolated pituitary deficiency of ACTH, resulting in secondary adrenal insufficiency. The defect in ACTH secretion was apparently due to intrinsic pituitary rather than hypothalamic disease, because administration of lysine vasopressin did not stimulate ACTH release. An empty sella with hyperprolactinemia has been described before. However, to the authors' knowledge, isolated ACTH deficiency as a complication of postpartum hypopituitarism (atypical Sheehan's syndrome) in association with an empty sella and hyperprolactinemia has not previously been reported.
