Thrombotic thrombocytopenic purpura (TTP) is a rare and often fatal disorder characterized by thrombocytopenia, microangiopathic hemolytic anemia, mental status changes, and renal dysfunction. Central diabetes insipidus (CDI) is a rare disease due to anatomic lesions of the hypothalamicpituitary system associated with various underlying diseases, or trauma. We present an unusual case of TTP and CDI in a 47 year-old African American female who was admitted to our hospital with crampy abdominal pain and nausea. The patient had tachycardia, fever and hypotension. The patient subsequently became confused, developed seizures, and her renal function deteriorated. Bone marrow analysis showed adequate megakaryocytes while a peripheral smear revealed severe thrombocytopenia, polychromasia and schistocytes. The diagnosis of thrombotic thrombocytopenic purpura (TTP) was made and plasmapharesis initiated. Over the next few days, the patient developed severe polyuria with a rise in serum sodium. Central diabetes insipidus was diagnosed and DDAVP (desmopressin acetate, 1-deamino-8-D-arginine vasopressin) was given. However, DDAVP was stopped several times due to worsening thrombocytopenia. Renal function worsened and the patient expired. A review of the literature revealed only one case of report of TTP and central diabetes insipidus. Our case was the only one reporting the use of DDAVP in such a setting.

Gastroenteritis due to Escherichia coli O157:H7 occurs in young children and is associated with consumption of under cooked beef. Approximately 5-10% of patients will develop hemolytic uremic syndrome (HUS): renal failure, microangiopathic hemolytic anemia, and thrombocytopenia. A 6-year-old boy was admitted with abdominal pain, guaiac positive stool, decreased urine output and elevated creatinine levels. Hemodialysis was initiated upon rapid progression to anuria. On hospital day # 5 he developed acute abdominal pain, which was different from his initial assessment. Exam revealed focal tenderness in the right lower quadrant with localized guarding and rebound. Ultrasound demonstrated a dilated, fluid filled tubular structure in the RLQ concerning for appendicitis. Based on these findings the patient was taken to the operating room for a laparoscopic appendectomy. The patient had undergone dialysis the previous day and was preoperatively treated with DDAVP to minimize the risk of bleeding. The procedure occurred without complication and final pathology confirmed acute appendicitis. This case highlights the unique clinical scenario in which patients with HUS require operative intervention. Surgical procedures can be performed on these patients, however, all precautions should be taken to minimize the risk of bleeding, including the use of preoperative DDAVP.
