A new diagnostic approach to better identify antiphospholipid syndrome.

Antiphospholipid syndrome is an autoimmune disorder in which the body produces antibodies to its own phospholipids or plasma proteins. Antiphospholipid syndrome (APS) is associated with many pathologies with several clinical manifestations. It can occur as a primary disorder or may be secondary to connective tissue disorder or tumor. Anti-phospholipid antibodies were detected in two categories of patients: in one group with many clinical manifestations (such as thrombotic events, thrombocytopenia and miscarriages) and in the other group with few clinical manifestations. In the first group high levels of IgG and IgA antibodies resulted, in the other group low levels of IgM. The ratio male:female was 1:3.5. Out of the 700 patients examined, 12 resulted positive for anti-cardiolipin (aCL) and a-beta2-GPI (affected by APS), and 15 patients positive for aCL (with middle-high values) but negative for a-beta2-GPI. At this point, according to the guidelines, we could have stopped examining. Only by continuing diagnostic investigation for these 15 patients has it been possible to observe: 2 patients positive for anti-thrombin (important first marker in the diagnosis of venose and arterial thromboses), anti-phosphatidylserine and anti-phosphatidylinositol (markers for cerebral diseases and recurrent miscarriages); 1 patient positive for anti- phosphatidylserine; 1 patient positive for anti-phosphatidylinositol antibody; 1 patient positive for both anti-phosphatidylserine and anti-phosphatidylinositol; 10 patients positive only for anti-cardiolipin. According to the results obtained, and considering that a more accurate investigation permitted to better identify APS syndrome, we propose a new diagnostic procedure.

[Experience on the pancreatic function after an episode of acute biliary oedematous pancreatitis]. / Studio sulla possibile alterazione della funzionalità pancreatica dopo un episodio di pancreatite acuta biliare edematosa.

The authors have examinated 35 patients 4 - 5 years after a previous episode of acute oedematous biliary pancreatitis. 20 patients had been cholecystectomized while 15 had not been operated. The patients of the first group didn't show any impairment of the endocrine or exocrine pancreatic function while the patients who were not cholecystectomized in 4 cases on 15 showed an impairment of the exocrine pancreatic function valued with the elastase-1 test in the stools. In 2 patients there was also a slight impairment of the glucose metabolism. The authors suppose that the persistance of a biliary disease can affect the pancreatic function.
