1/5. hypertriglyceridemia, acute pancreatitis, and diabetic ketoacidosis possibly associated with mirtazapine therapy: a case report.A 44-year-old woman with a history of major depression and obsessive-compulsive disorder was prescribed mirtazapine. She came to the emergency department approximately 2 months after starting therapy; severe hypertriglyceridemia, acute pancreatitis, and diabetic ketoacidosis were diagnosed. Although these adverse effects have been reported in early clinical trials, we found only three published cases of subclinical pancreatitis possibly associated with mirtazapine therapy. We suspect that mirtazapine-associated hypertriglyceridemia had contributed to the development of acute pancreatitis and diabetic ketoacidosis in our patient. All these problems resolved with supportive care and discontinuation of mirtazapine. Her serum amylase, lipase, and lipid levels were normal 2 months after the acute event occurred. health care providers should be aware of these possible adverse effects. serum glucose and triglyceride levels should be measured at baseline and monitored regularly thereafter in all patients receiving mirtazapine therapy.- - - - - - - - - - ranking = 1keywords = hypertriglyceridemia (Clic here for more details about this article) |
2/5. Pseudonormoglycemia in diabetic ketoacidosis with elevated triglycerides.A 24-year-old newly diagnosed male patient with diabetes presented with diabetic ketoacidosis (DKA) (pH 7.16, HCO3 6.0) and extreme hypertriglyceridemia (239.35 mmol/L). The diagnosis of DKA was delayed because of the apparent depression of the true serum glucose (to 11 mmol/L). He was treated with intravenous (IV) insulin and rehydration, which normalized his pH, HCO3, and triglyceride levels. To the authors' knowledge, this is both the highest triglyceride level recorded and the first report of a high triglyceride level as the apparent cause of a factitiously low glucose level.- - - - - - - - - - ranking = 0.5keywords = hypertriglyceridemia (Clic here for more details about this article) |
3/5. Recurrent ketoacidosis in acquired, total lipodystrophy (lipoatrophic diabetes).The absence of ketoacidosis is thought to be characteristic of generalized lipoatrophic diabetes. It is widely believed that lipoatrophic diabetic patients are able to tolerate starvation and therapeutic insulin withdrawal, due to absence of subcutaneous body fat, the substrate essential for ketogenesis. In this article, we document nine episodes of acidosis and accelerated ketone body formation in a 24-yr-old woman whose deterioration followed episodes of dietary excesses without evidence of intercurrent infection or other identifiable forms of metabolic stress. serum c-peptide measurements demonstrated that an absolute insulin deficiency did not exist. During short-term, experimental, dietary manipulations, excess dietary calories worsened the hyperglycemia and hyperlipidemia but did not reproduce the ketoacidotic state. Excess fat added to the diet was the most poorly tolerated of the food groups, causing ketonuria, hypertriglyceridemia, and abdominal pain. Our experience with this patient suggests that increased food consumption, insufficient insulin relative to an insulin-resistant state, and increased amounts of insulin counterregulatory hormones (stress), acted in concert to cause acidosis and increased ketone body formation.- - - - - - - - - - ranking = 0.5keywords = hypertriglyceridemia (Clic here for more details about this article) |
4/5. The urine anion gap: the critical clue to resolve a diagnostic dilemma in a patient with ketoacidosis.Usually, ketoacidosis presents few if any diagnostic or therapeutic problems; in this article, we report a case where ketoacidosis was clinically occult and biochemically obscure. The patient presented with acute pancreatitis associated with a modest antecedent alcohol intake. Metabolic acidosis with a normal anion gap (10 meq/L) was observed together with moderate hyperglycemia and a 2 (but not 4 ) test for serum ketones. None of the usual causes of metabolic acidosis with a normal anion gap was identified nor was there an obvious explanation for a reduction in unmeasured anion gap (e.g., hypoalbuminemia, dysproteinemia, or the presence of abnormal halides). Despite the initial normal anion gap, ketoacidosis was suspected clinically and this was confirmed by the elevated serum B-hydroxybutyrate of 8 mmol/L. We deduced that the serum unmeasured anions, which should have been increased by at least 8 meq/L, were being underestimated because of the effect of hypertriglyceridemia on the serum chloride determination. When the serum chloride was reestimated by a method not influenced by hyperlipidemia, the value was 102 mmol/L not 112 mmol/L and, when reevaluated, the anion gap was indeed appropriately elevated. In addition, the urine anion gap (Na K - Cl) was 103 meq/L in the absence of renal disease. This indicated that the expected large quantity of urinary ammonium must have been masked by an even greater quantity of unmeasured anion; in this case proven by direct measurement to be B-hydroxybutyrate. Finally, metabolism of the alcohol ingested, which yields hepatic NADH, could explain, in part, the modest hyperglycemia and the absence of a 4 test for serum ketones.(ABSTRACT TRUNCATED AT 250 WORDS)- - - - - - - - - - ranking = 0.5keywords = hypertriglyceridemia (Clic here for more details about this article) |
5/5. Treatment by plasma exchange of a patient with hyperlipidemia and diabetic ketoacidosis with lesional pulmonary edema and acute pancreatitis.The authors report a case of severe hypertriglyceridemia (148.5 mmol/l) in a 27-year-old woman admitted for coma of unknown origin. Initial investigations revealed ketoacidosis, pancreatitis and noncardiogenic pulmonary edema. The diabetes was unknown. Ketoacidosis was rapidly controlled. The hypertriglyceridemia was corrected by one course of plasma exchange (4,400 ml) during which the patient returned to consciousness. The patient recovered without any sequelae. Only 2 similar cases, treated by plasma exchange, have been reported in the literature until now.- - - - - - - - - - ranking = 1keywords = hypertriglyceridemia (Clic here for more details about this article) |
