Acute severe intravascular haemolysis: an unrecognised cause of pancreatitis.

چکیده
study showed a significant reduction in lower oesophageal sphincter pressure after intramuscular administration of emepronium bromide. In the nine patients who completed the study no significant change in sphincter pressure was found after four weeks' treatment with a standard oral dose of emepronium bromide. This may have been due to the much lower serum concentrations seen after oral medication than after intramuscular injection, confirming the findings of Ritch et al.5 A local irritative effect of the tablets is probably the most common cause of oesophageal injury after oral medication, as no decrease in sphincter pressure was shown during oral treatment with emepronium bromide. Since, however, higher plasma concentrations ofemepronium bromide decrease the sphincter pressure and the absorption of the drug from the gastrointestinal tract varies considerably, occasional high serum concentrations may be seen. This, combined with an individual variability in parasympathetic receptor sensitivity, might cause the lower oesophageal sphincter to relax, causing more severe cases of reflux oesophagitis in the lower oesophagus.

متن کاملVillous adenoma in a blind duodenal loop.
Serum amylase levels in patients in this type of coma without clinical evidence of pancreatitis have seldom been reported and have usually been normal. The level reported in the present patient was raised but not enough to be diagnostic of acute pancreatitis. Although acute renal failure does produce raised levels it is unlikely to have been the cause here, because the amylase level fell to nor...
متن کاملAcute intravascular haemolysis associated with intravenous administration of meropenem in a sixty four year old man.
We present the first reported case of severe intravascular haemolysis associated with the use of meropenem in a 64 year old man. The report highlights a further possible drug related cause of intravascular haemolysis. The patient, who had a background of dialysis dependent renal failure, epilepsy and learning difficulties, was admitted to the intensive care unit following laparotomy and large b...
متن کاملAcute viral hepatitis, intravascular haemolysis, severe hyperbilirubinaemia and renal failure in glucose-6-phosphate dehydrogenase deficient patients.
Five patients with acute viral hepatitis developed severe intrasvascular haemolysis and unusually high levels of serum bilirubin (427 to 1368 mumol/l). All 5 had high fever, marked anaemia, reticulocytosis and neutrophilic leucocytosis. Three of them developed acute renal failure, which was of non-oliguric type in 2. The clinical course was protracted, but complete recovery occurred in 4 patien...
متن کاملFamilial hypertriglyceridemia-induced acute necrotizing pancreatitis: A case report
Acutepancreatitis can infrequently be a life-threatening complication of hypertriglyceridemia. Rarely, hypertriglyceridemia can originate from an inborn genetic error in lipoproteins metabolism. This condition can be manifested by very high serum triglyceride levels (>1000 mg/dl) and a more severe and lethal form of pancreatitis. Here, we present a case of acute pancreatic which was found out t...
