In this case report, the patient had been delivered by Caesarean section and weighed only 4 pounds at birth. The mother was O negative, the father A positive, and the infant A positive. Initial red cell count was 2.85 million/cu mm; white cell count, 19,200/cu mm; and hemoglobin 70% of normal. At 3 months of age hemoglobin was 10% of normal. Bone marrow examination revealed marked erythroid hyperplasia. A diagnosis of Blackfan-Diamond syndrome was made. He received blood transfusions every 2 or 3 weeks for the first 4 years of his life. During his lifetime he received 433 units of packed cells for the treatment of congenital hypoplastic anemia. Vitamin-B12, folic acid, and iron were given without benefit. At 8 years of age a spelectomy was done. 20 months after surgery he recovered from pneumonococcal meningitis without sequelae. Progressive signs of hemochromatosis developed and finally progressive signs of heart failure with edema. At 24 years of age severe epigastric pain developed. An open liver biopsy disclosed multiple liver nodules which proved to be hepatoma. Severe ascites followed the surgery. Pulmonary metastases of the liver tumor developed and heart failure. He died at age 25. This patient had received no androgen. He was consistently hepatitis antigen negative. He was prepubertal at the age of 25 and had almost no endogenous androgens. Alpha-fetoglobin was present. This test may be useful as a screening test for hepatoma.

A consecutive series of 24 cases of primary carcinoma of the liver in Malawi has been investigated. Histologically, all were hepatocellular carcinomas (HCC). All patients were African Bantus, the average age was 42.7, and the sex ratio was men 3.5:women 1. The duration of symptoms attributable to HCC was about 5 months previous to admission to hospital and was in no case preceded by clinically manifest cirrhosis. The clinical picture was rather uniform with pain in the region of the liver, emaciation and nodular hepatomegaly as the most important features. One of the patients had repeated attacks of hypoglycaemic coma. Sera from 11 out of 13 patients contained alpha-feto-protein. Hepatitis-associated antigen and antibody in the serum were found in 7 and 6 out of 16 and 14 cases respectively. Serum B12 and serum unsaturated B12 binding capacity were moderately raised in most patients. The prognosis was poor, the average time of survival was 4.8 weeks after admission. The cause of death was most frequently hepatic coma. HCC in the African Bantu shows some different features from the same disease in the Western Hemisphere: The incidence is much higher; the patients are younger. The neoplasm commonly develops in a clinically latent cirrhosis. The latter is not caused by alcohol, but is presumably a sequel of hepatitis. It is possible that aflatoxin is the carcinogenic factor, acting more readily in a cirrhotic than in a normal liver.

Twenty-five patients with chronic active hepatitis triggered by external factors (viruses or drugs) and 20 patients with cryptogenic chronic active hepatitis were studied for two to five years. The first group showed a significantly higher frequency of clinical and biochemical resolution at the end of the observation period than did the second group. The group with cryptogenic disease had a predominance of females carrying the histocompatibility antigen HLA-B8, whereas the group with virus- or drug-induced hepatitis did not differ from normal controls in regard to the distribution of HLA antigens. HLA-B8 and HLA-B12 were found in all but two patients in the group with cryptogenic hepatitis; this group of patients had elevated levels of gamma-globulin and autoantibodies in their sera more frequently than did the group with virus- or drug-induced disease. The results suggest that there are at least two types of chronic active hepatitis: one genetically determined, with signs of enhanced immunoreactivity and with a low degree of healing in five years; and another type triggered by external factors and without predisposing genetic factors. The data suggest that the clinical outcome is more favorable for patients with the second type of chronic active hepatitis.

A controlled clinical trial comparing 2-Mercapto-Priopionyl-Glycine (2-MPG) plus B12 vitamin with B12 vitamin alone in chronic liver disease has been conducted in seven hospitals in Italy. Patients were divided into two groups on the basis of liver histology; group I included 26 patients showing histological evidence for chronic persistent hepatitis (C.P.H.) (according to De Groote et al.) whereas group II consisted of 54 patients with chronic aggressive hepatitis (C.A.H.) or compensated liver cirrhosis. Patients of each group were randomly allocated to 2-MPG plus B12 vitamin, or to placebo plus B12 vitamin, in a double-blind way. The drug (or placebo) was diluted in 500 ml of 10% Levulose, and administered intravenously; 1000 gamma of B12 vitamin were added to each bottle. Patients in the 2-MPG group received 2.5 gms of the drug daily; the treatment lasted for 30 days. The following parameters were checked in all patients on admission, and repeated at the end of treatment: Serum bilirubin, serum Cholesterol, A.P., BSP retention, Prothrombin time, S-GOT, S-GPT, Gamma-GT, Total serum Protein, serum electrophoresis, Immunoglobulins. Patients given 2-MPG showed significant decreases of serum transaminases, and improvement of BSP retention.

A comparative study of the hepatoprotective effect of carnosine and 4-methyluracil under CCl4-induced acute toxic hepatitis has been carried out. The extent of liver injury and its regeneration were established from morphological data as well as from changes in the activities of alanine aminotransferase (ALT) and histidase and the bilirubin content in blood serum. Hyperlipoperoxidation in the liver and serum was assessed by the amount of TBA-active products. It was found that by day 10 of experimental hepatitis ALT and histidase levels in blood sera of untreated animals exceeded the normal values 1.3- and 3.9-fold, whereas those in the carnosine-treated group approximated the values characteristic of intact animals. The activity of serum ALT in animals treated with vitamin B12 or 4-methyluracil exceeded normal values 1.5 and 1.6 times, whereas that of histidase was 2.5 and 2.7 times as high. Carnosine and 4-methyluracil inhibited (in approximately the same degree) the formation of TBA-active products in the liver. According to morphological dta, cessation of CCl4 injections was accompanied by rapid regeneration of liver tissues in all animal groups. Carnosine enhanced regenerative processes in parenchymatous and connective tissues in a far greater degree in comparison with other drugs. The mitotic index in the carnosine-treated group exceeded more than twofold the corresponding parameters in untreated animals. Possible mechanisms of carnosine action on liver repair are discussed.

A 76 year old female with atypical leukemia complicated by vitamin B12 deficiency demonstrated marked fluctuation in blast percentage and hemopoiesis over 8 month period. She underwent surgical removal of pancreas head cancer 5.5 years ago. In January 1989 severe pancytopenia and mild increase of bone marrow blast were found. Blood transfusions and inadvertent administration of Vitamin B12 resulted in alleviation of pancytopenia and decrease in blast percentage. Several months later her bone marrow blast exceeded 30%, when serum B12 concentration was below 90 pg/ml. B12 injection and blood transfusion resulted in significant improvement in her hematological condition, but shortly thereafter she died of fulminant hepatitis. Her bone marrow cells showed a polyclonal constitution, as assessed by the RFLP-methylation technique using the PGK gene as a probe. The coexistence of leukemic- and normal clones under Vitamin B12 deficiency conditions and the differing behavior of such clones to B12 supplementation may explain the unusual clinical course observed in this patient.

The aim of the present work was to perform a prospective analysis of the significance of macrocytic red cells through the study of all patients with MCV higher than 105 fl (those treated with cytotoxic or immunosuppressing drugs were excluded). Conventional clinical, haematologic and biochemical studies were carried out on every patient, along with B12 and folate levels, bone marrow examination and bone marrow karyotype and, whenever B12 deficiency was present, complete Schilling's test. Special attention was paid to the aetiological inquiry and post-therapeutical course. A series of 109 patients was collected. Decreased serum B12 rates with abnormal Schilling's test and response to parenteral therapy were present in 26 cases (24%). Of them, 22 fulfilled the diagnostic criteria for Biermer's anaemia, while in the remaining 4 there was impaired intestinal absorption. Serum or red-cell folate deficiency was found in 34 other cases (31%). Alcoholism was present in 20 of them, abnormal diet in 10, malabsorption syndrome in 2, and excessive demands in 2 others. Hence, vitamin deficiency underlay macrocytosis in 60/109 cases (55%). In the remaining 49 cases (45%) macrocytosis was not accompanying folate or B12 deficiency. Of these, severe liver disease was found in 16 patients (alcoholic in 15 and post-hepatitis in 1 case), with increased serum B12 in 10 cases and increased serum or erythrocytic folate in 3 others. Nineteen patients within this group had primary myelodysplastic syndromes (RA, 8; SRA, 4; RAEB, 7), and the remaining 14 cases had several haematological (AIHA, 4; CLL, 1, T-cell lymphoma 1, M-6, 1, and myelofibrosis with myeloid metaplasia, 2) or non-haematological diseases (heart insufficiency, 2; COPD,3).(ABSTRACT TRUNCATED AT 250 WORDS)

Studies were undertaken in 32 patients with hepatitis B-negative or -positive chronic active hepatitis or chronic persistent hepatitis to define the relationship between immunoregulatory activity and the HLA-B8 and B12 phenotypes. Suppressor T-cell activity measured by a concanavalin A-induced suppressor system using allogeneic responder cells was dependent on which individual was selected as a source of responder cells. No differences were noted using isogeneic cells as responders. Suppressor T-cell activity measured by the effect of a noninduced suppressor cell on a mixed leukocyte culture was not different from controls. Increased prostaglandin-producing suppressor cell activity was found in patients with hepatitis B-negative (p less than 0.005) and hepatitis B-positive (p less than 0.05) chronic active activity hepatitis. When results of the suppressor activities were compared among patients with chronic hepatitis dependent on the presence of HLA-B8, B12, or neither of these phenotypes, no significant differences were present. These results provide further evidence of altered immunoregulatory function in patients with chronic active hepatitis, which may reflect increased suppression by a population of prostaglandin-producing suppressor cells. The results do not, however, suggest that a gene coding for altered immune regulation is linked to HLA-B8 or B12.

Antitoxic properties of cobamamide, a coenzymic form of vitamin B12, were studied in experimental toxic hepatitis induced by CCl4. The data obtained as a result of the assessment of the bromosulfalene test and activity of sorbitol dehydrogenase and alanine aminotransferase point to a demonstrable hepatoprotective action of cobamamide. Normalization of the indicators studied evidences that the drug intensifies the recovery processes occurring in the liver of rabbits with toxic hepatitis.

In eight patients with clinical sure Vogt-Koyanagi Harada-syndrome (VKHS) immunological examinations were performed. We tested whether there were signs of former or present infections (measles HHT and complement fixation test (C.F.T.), rubella HHT, hepatitis HBs-antigen, adenovirus AG, varicella-zoster C.F.T., herpes simplex C.F.T., cytomegaly IgM and IgG, toxoplasmosis immunofluorescence, tuberculosis Middlebr. Dubois). In none of all cases we could find HLA B12. The rheumatic tests, LDH, albumin an electrophoresis, coeruloplasmin and haptoglobin were negative. The uveal pigment failed to stimulate the leucocyte cultures from VKHS-patients in leucocyte-migration-inhibition-test and in leucocyte-adherence-inhibition-test.
