RESUMO
Postprandial hypotension (PPH) is characterized by a drop in blood pressure (BP) of at least 20 mmHg within 15 minutes to two hours after any meal. This phenomenon is observed in approximately half of patients with type 2 diabetes mellitus and can also affect otherwise healthy elderly patients. Prolonged instances of PPH can cause serious complications, including but not limited to dizziness, frequent falls, weakness, and even loss of consciousness. Nonpharmacologic interventions can help, such as discontinuing any exacerbating medications, increasing salt and water intake, adopting lifestyle modifications, and engaging in muscle tension-reducing exercises. When these strategies fail, pharmacological treatments may become necessary. Medications like midodrine (an alpha-adrenergic agonist) or droxidopa (a norepinephrine precursor) are commonly prescribed to help maintain BP. However, should BP persistently remain low despite these interventions, alternative therapies are explored. Acarbose, an antidiabetic medication, is an alpha-glucosidase inhibitor that targets pancreatic alpha-amylase and membrane-bound intestinal alpha-glucoside hydrolase. The inhibition slows glucose absorption, further reducing postprandial glucose blood concentrations. This case report presents the management of a 67-year-old woman with persistent PPH that is unresponsive to midodrine, atomoxetine, and sodium chloride tablets. The addition of acarbose to her regimen yields appropriate maintenance of BP after meals. The patient was able to be safely discharged home after.
RESUMO
Autoimmune polyendocrine syndrome type 2, also known as Schmidt's syndrome, is a rare autosomal dominant life-threatening syndrome. It is defined by the presence of Addison's disease in combination with at least one of the known autoimmune diseases: thyroid autoimmune disease, type 1 diabetes, and hypogonadism. It is more common in middle-aged females and is treatable if diagnosed early. However, in this case, we report Schmidt's syndrome in a young male without a family history. A 20-year-old male with a past medical history of hypothyroidism, adrenal insufficiency, and type 1 diabetes presented to the emergency department (ED) feeling lethargic, somnolent, and diaphoretic. Laboratory blood tests showed elevated thyroid-stimulating hormone, hyperkalemia of 6.4 mmol/L, and hyponatremia of 131 mmol/l indicating an Addisonian crisis. The patient had low blood glucose (at home: 60 mg/dL, and at ED: 85 mg/dL), hypotensive blood pressure of approximately 85/55 mmHg, and a peaked T-wave on EKG, which were consistent with the diagnosis of Schmidt's syndrome. Based on the laboratory findings and history, the patient was diagnosed with polyendocrine syndrome Type 2 (Schmidt's syndrome). The patient was treated for adrenal insufficiency first followed by thyroid insufficiency. Schmidt's syndrome is a rare disease and difficult to diagnose because the presentation depends on which gland is initially involved. A few cases have been reported in the literature of atypical presentations of Schmidt's syndrome. Therefore, this case report can contribute to the medical literature on Schmidt's syndrome, which can help in early diagnosis and improve patient outcomes.
