Protein C and antithrombin III in polytransfused thalassemic patients.
Seventy-four patients with beta-thalassemia major were studied to test the hypothesis that a deficiency of protein C (PC) and antithrombin III (AT III), both antithrombotic proteins, could contribute to the pathogenesis of CNS thromboembolic lesions. In 70 patients, PC levels were found to be significantly lower than normal, whereas AT III activity was found to be lower only in 41 patients. The lowest values of PC and AT III were found in older splenectomized patients, a low PC value only was found in chronic hepatitis patients. Prothrombin time and fibrinogen were found to be particularly abnormal in patients with chronic hepatitis and without spleen. A relatively poor correlation was observed between PC and AT III (p less than 0.02). PC correlated with age (p less than 0.001), transfusional iron (p less than 0.001) and ferritin (p less than 0.001). It also correlated with serum albumin (p less than 0.001), prothrombin time (p less than 0.001) and fibrinogen (p less than 0.02) and with serum transaminases (GPT) (p less than 0.001). The same indexes correlated less significantly with AT III activity. Nevertheless, only 2 of our patients had CNS thromboembolic complications. It is probable that low clotting factors, hyperfibrinolysis and thrombocytopenia (which are common in chronic liver disease) could have the opposite effect on hemostasis from that of low levels of anticoagulant proteins such as PC and AT III.

Homozygous NADH-methemoglobin reductase and aspartylglucosaminidase deficiencies in a moderately retarded Sicilian child.
We report on a 10-year-old boy with generalized deficiency of both NADH-methemoglobin reductase and aspartylglucosaminidase. Although the two enzymatic defects, both autosomal recessive traits, are associated with severe mental retardation, the patient was less retarded than his sister who had only aspartylglucosaminuria.

[Neonatal cholestasis : clinical and diagnostic setting].
A retrospective study of 112 infants admitted at Pediatric Clinic of Catania from 1970 to 1985 with diagnosis of "Cholestatic jaundice" shows two prevalent pathologies: neonatal hepatitis and biliary atresia. Some other disease like cystic fibrosis. Hereditary fructose intolerance, Galactosaemia, Paucity of bile duct were found rarely. Some laboratory parameters (Serum direct bilirubin, Alkaline Phosphatase, Alkaline Phosphatase/Transaminase (GOT) show a characteristic pattern. Therefore the analysis of these data could help us to make a probability diagnosis and anticipate the liver biopsy that remain the most sensitive diagnostic instrument. In fact it is known that the earlier diagnosis is very important for the prognosis of these infants.

[Alpha 1-antitrypsin in thalassemia major].
The authors investigated a possible relationship between alpha 1-antitrypsin (alpha 1AT) phenotypes, serum levels of alpha 1AT and liver disease in transfusion dependent thalassemia major subjects. The distribution of alpha 1AT phenotypes suggest the absence of association between alpha 1AT variants and thalassemic genes and underlines again the low incidence of pathologic variants in Italian population. Mean concentration of alpha 1AT was significantly increased in thalassemic patients and was not related to transaminase levels. These results show that other factors are responsible for the development of liver disease in transfusion dependent thalassemic subjects.
