The present study reported on an unusual case of refractory hypotension induced by Sheehan syndrome with pituitary crisis and explored the causes and treatment of hypotension in hypopiptuitarism. Refractory hypotension is a rare and severe complication of longstanding hypopituitarism induced by Sheehan syndrome with pituitary crisis. A 48-year-old Chinese woman with pituitary crisis due to Sheehan syndrome developed refractory hypotension and received longstanding vasopressor blood pressure support and hormone replacement therapy. Besides normalized blood pressure, echocardiography over 3 months revealed partial reversibility of her cardiac function with hormone replacement therapy. Consistent numerous studies reviewed, hormone replacement therapy may improve cardiac function in patients with cardiomyopathy linked to Sheehan syndrome. A retrospective study of 77 cases with hypopituitarism encountered at Qilu Hospital of Shandong University (Jinan, China) was also performed and the incidence rate of hypotension was analyzed, revealing that the present case was the first of refractory hypotension induced by Sheehan syndrome with pituitary crisis at this institution in 16 years.

Polyneuropathy, organomegaly, endocrinopathy, M proteins, and skin changes (POEMS) syndrome is a rare variant of plasma cell disorders with multiple systemic manifestations. A 50-year-old female patient presented with progressive weakness in her upper and lower limbs; tingling, numbness and burning in her feet; polyneuropathy (demyelinating in the majority of cases of POEMS syndrome); monoclonal plasma cell disorder (typicallyλ-restricted in cases of POEMS syndrome); sclerotic lesions on the spine and pelvis; organomegaly, including hepatomegaly, splenomegaly and lymphadenopathy; edema; pleural effusion; adrenal, thyroidal, pituitary, gonadal and pancreatic endocrinopathy; skin changes, including hyperpigmentation, dry skin and hypertrichosis; thrombocytosis; pulmonary hypertension; low vitamin B12 and weight loss. Following the diagnosis of POEMS syndrome, the patient was treated only with pain-alleviating corticosteroids. Respiratory failure-induced mortality occurred 24 months after the patient first experienced difficulty walking and numbness in her lower extremities. The present study suggests that abnormal symptoms in cases of POEMS syndrome should be further evaluated during the diagnosis and treatment.
