1/3. Alpha-1-antitrypsin deficiency and liver in adults.Thirteen adult patients (aged 16 to 73 years) form 12 families are described with liver disease and alpha- 1- antitrypsin deficiency. Long-term observation of several of these patients suggests that the liver disease may be only slowly progressive, but review of possible factors aggravating this has failed to reveal any obvious clues. Progression to death from hepatic failure was the commonest outcome, but one patient developed a malignant hepatoma and two others died because of intraperitoneal haemorrhage due to ruptured cirrhotic nodules--a complication not hitherto described in association with this condtion. diagnosis of alpha-1-antitrypsin deficiency was based on serological, histological, immunopathological and genetic studies. The most useful screening test in liver disease was found to be the demonstration of PAS positive globules in liver biopsy material which is diagn by immunofluoresence or immunoperoxidase, the latter being a superior technique. serum estimation of alpha-1 -antitrypsin deficiency was performed by immunoelectropharetic and immunodiffusion techniques, the former being preferred because it gave more consistent results. Both methods, however, were of limited value since wide variations in the serum values are commonly found in normal and abnormal states. Genotyping was carried out using starch gel electrophoresis and although of value in family studies, its value as a diagnositc aid is limited because of technical difficulties and also because alpha-1-antitrypsin accumulation in the liver may be found in both homozygous and heterozygous states. It is suggested that adult liver disease associated with abnormalities in alpha-1-antitrypsin may be more common than has hitherto been reported. This condition should be systematically sought in all cases of liver disease of uncertain aetiology.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
2/3. brain haemorrhage in five infants with coagulopathy.Most intracranial haemorrhages in infants after the neonatal period are secondary to non-accidental injury. Occasionally brain haemorrhages in non-mobile infants are due to an inherited coagulopathy. This may often be diagnosed with a coagulation screen on admission. Little is known about the neurological outcome of infants in the latter group. Five infants are described who presented with acute spontaneous brain haemorrhage secondary to an inherited coagulopathy (n = 3) and vitamin k deficiency in alpha(1) antitrypsin deficiency (n = 1) and Alagille's syndrome (n = 1). Despite the critical clinical presentation and the severe imaging findings, these five infants made a good neurological recovery. Infants presenting with spontaneous ICH due to a significant (inherited) coagulopathy are usually easy to differentiate from non-accidental shaking injury; their bleeding pattern within the brain seems different from non-accidental shaking injury and neurodevelopment outcome appears better.- - - - - - - - - - ranking = 7keywords = haemorrhage (Clic here for more details about this article) |
3/3. Complex extra-intestinal complications of ulcerative colitis in a patient with alpha1-antitrypsin deficiency.Ulcerative colitis (UC) can manifest with a variety of extra-intestinal disorders frequently affecting the skin, joints, and liver. An aetiologic role of alpha1-antitrypsin deficiency in chronic inflammatory bowel disease has recently been suggested. We report a patient with UC and alpha1-antitrypsin deficiency who presented with disseminated cutaneous leucocytoclastic vasculitis clinically appearing with target-like purpuric patches and haemorrhagic oedemas. In addition, he displayed acute haemorrhage of the eyes and the respiratory tract consistent with a systemic vasculitic process. Moreover, he had autoimmune haemolytic anaemia. Systemic vasculitides, such as Wegener's granulomatosis, churg-strauss syndrome, and microscopic polyangiitis, could widely be excluded. Systemically administered glucocorticosteroids and azathioprine led to dramatic improvement of extra-intestinal symptoms. On the basis of alpha1-antitrypsin deficiency and UC, the present patient likely developed severe systemic vasculitis with multi-organ involvement. UC should at times be viewed within the context of a more generalized immune imbalance affecting multiple organs, and not as an isolated pathological entity. Testing for alpha1-antitrypsin deficiency in UC patients may detect individuals at higher risk of severe extra-intestinal involvement.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
