CD45 antigen (leukocyte common antigen), a unique and ubiquitous membrane glycoprotein with a molecular mass of about 200 kDa, is expressed on almost all hematopoietic cells except for mature erythrocytes. However, the biological function of this glycoprotein still remains to be resolved. In order to clarify the role of CD45 antigen in hematopoietic cell differentiation and function, its expression on human leukemia/lymphoma cell lines was studied by membrane immunofluorescence. Thirty-eight established cell lines were analyzed using T29/33, a monoclonal antibody (MoAb) that recognizes the common epitopes of this glycoprotein molecule. Conventional cell marker studies were also carried out on these cell lines to compare their CD45 expression. It was shown that CD45 expression varies among B-lineage cells depending on cell differentiation, in contrast to its stable expression on leukemic T cell (6/6, positive) and myeloid (5/5, positive) lineage cell lines. On the other hand, only two out of six histiomonocytoid lineage cell lines were positive. Human T cell leukemia/lymphoma virus type I (HTLV-I)-associated T cell lines derived from peripheral blood leukocytes of patients with adult T cell leukemia/lymphoma (ALT/L) in Japan did not express CD45 on their cell surface. Taken together, these observations suggest that CD45 has a functional role in hematopoietic cell activation and differentiation.

In the period 1970 to 1987, 171 patients with small-intestinal mucosal atrophy have been hospitalized in our department. Of these, 132 patients fulfilled the diagnostic criteria of coeliac disease on the basis of histologic findings and clinical improvement on a gluten-free diet. Aspartate aminotransferase (ASAT), alanine aminotransferase (ALAT), and alkaline phosphatase (ALP) were chosen as markers of hepatic involvement. Elevation above the normal range in one or more of these tests was seen in 62 patients (47.0%, group I). In 70 patients (53.0%, group II) of similar age the levels of these variables were normal. In group I, 14 (10.6%) patients had an elevation of ALP only, leaving 48 (36.4%) patients with pathologic values for one or both transaminases. In group I, 32 patients had their ASAT, ALAT, and ALP reexamined after at least 6 months of gluten-free diet. Among the patients with increased values of one or both transaminases 18 patients were tested before and at least 6 months after start of gluten-free diet. The variables were significantly reduced in all patients. Liver biopsies were performed in 37 patients, and findings were normal in 5. In 25 patients the changes were classified as non-specific. Chronic active hepatitis was demonstrated in five patients. In one of these patients primary sclerosing cholangitis and ulcerative colitis were also diagnosed. Concomitant malignant disease was found in 22 patients, of whom 16 had malignant lymphoma. Malignant disease was seen more often in group I than group II (p less than 0.01). In conclusion, liver lesions were found in a great proportion of the patients with coeliac disease.(ABSTRACT TRUNCATED AT 250 WORDS)

All cases of liver tumor referred to the King Faisal Specialist Hospital and Research Centre in Saudi Arabia during 2.5 years were reviewed. Hepatocellular carcinoma, 104 cases, was considerably more common than metastatic carcinoma with unknown primary, 15 cases. Lymphoma presenting as liver tumor occurred in three cases and there were no cases of cholangiocarcinoma. There were only two cases of benign tumor, both hemangioma. Hepatocellular carcinoma was characterized by a male predominance of 6:1, positive hepatitis B surface antigen in 60%, presentation with an enlarged, hard liver in over 90%, a systolic-diastolic bruit over the mass in 45%, a single highly echogenic lesion in the right lobe on ultrasound in 80%, and rapid progression. The serum AST (aspartate aminotransferase, serumglutamic oxalacetic transaminase [SGOT]) was abnormal in 97% and was higher than the alanine aminotransferase (ALT) in 93% of cases compared with 17% in 100 consecutive cases of chronic active hepatitis. Sixty-six percent of patients with hepatocellular carcinoma had serum AFP greater than 200 ng/ml. Excluding five cases of germ cell tumor (none involving the liver), and pregnant patients, serum AFP was less than 200 ng/ml in all other patients in whom it was measured between 1979 and 1981. A practical approach to the diagnosis of hepatocellular carcinoma is outlined. Biopsy does not appear to be indicated in many cases of advanced hepatocellular carcinoma.

A clinical phase II study of recombinant human leukocyte interferon A (rIFN-alpha A, Ro 22-8181) for various skin malignant tumors was jointly conducted at nine medical institutes across the country in order to study its clinical effect and side effects. Patients received Ro 22-8181 alone in doses ranging from 3 X 10(6) U/day to 50 X 10(6) U/day either by intramuscular injection or by local injection. Good response was obtained in one (4.8%) of 21 patients treated by intramuscular injection and in 26 (72.2%) of 36 patients treated by local injection. The percentage of good responses achieved by local injection for individual diseases was 55.6% (5/9) for metastatic malignant skin melanoma, 100% (11/11) for cutaneous malignant lymphoma, 100% (5/5) for extramammary Paget's disease, 75% (3/4) for intraepidermal cancer and 50% (2/4) for metastatic skin cancer. Main side effects were fever, anorexia, general fatigue, chills, nausea and vomiting. Abnormal laboratory data included leukopenia, and elevation of GOT and GPT, although their incidence was lower with local injection than with intramuscular injection. Side effects were mostly improved by reduction of the dose or discontinuation of the treatment.

The results of 25 percutaneous biopsies of the liver from 24 patients with non-Hodgkin's lymphoma are reported. In all cases, the value of their serum biochemistry (LDH, GOT, GPT and/or alkaline phosphatase) was abnormal and sufficient tissue material was biopsied to obtain a histopathological evaluation. Specimens from five ultrasonically suspected lymphoma of the liver showed tumor involvement histopathologically. Diffuse tumor involvement was also histologically found in three ultrasonically unsuspected livers. Six liver specimens showed degenerative and/or fibrotic change in the new and previously treated patients.

A 55-year-old man was admitted to our hospital with fever, ascites, generalized lymphadenopathy and hepatosplenomegaly. A cervical lymph node was biopsied and diagnosed as a diffuse mixed cell type B-cell malignant lymphoma with positive cytoplasmic IgM in plasmacytoid lymphocytes and immunoblasts. Serum protein electrophoresis disclosed a monoclonal peak and immuno-electrophoresis identified the abnormal protein as IgM kappa(k). Serum immunoquantitation revealed an IgM level of 1470 mg/dl. Bence-Jones protein of the k type was positive in the urine. Cryoglobulin with the characteristics of IgM was present in the serum. In peripheral blood, hemoglobin was 12.4 g/dl, WBC 26,500/microliters with increased abnormal cells and the platelet count 2.2 x 10(4)/microliters. Low fibrinogen and high FDP levels indicated the existence of disseminated intravascular coagulation (DIC). Gabexate mesilate (FOY) was administered at a dose of 1,000 mg/day for the DIC with very good response. After one course of combination chemotherapy (vincristine, cyclophosphamide, prednisolone, adriamycin), he achieved complete remission. However, three months later, he showed icterus and anorexia again with high levels of serum GOT and GPT and positive HBs antigen. On the 117th hospital day, he became abruptly developed right hemiplegia and coma. Cranial CT demonstrated massive thalamic bleeding in the left hemisphere with ventricular rupture, and he died on the same day.

Infected patients with hematological disorders were treated with the combination of cefmenoxime (CMX) and cefsulodin (CFS). This therapy was done on 74 patients, of whom 38 (51%) had acute myelocytic leukemia, 14 (19%) malignant lymphoma, 7 (9%) acute lymphocytic leukemia, 5 aplastic anemia, 4 adult T cell leukemia, 4 chronic myelocytic leukemia, 1 multiple myeloma and 1 histiocytic medullary reticulosis. Complicated infections included 5 cases of septicemia, 41 cases of suspected septicemia, 19 cases of respiratory tract infection, 2 with anal abscess, 1 with urinary tract infection and others. The obtained results were as follows: Clinical effectiveness of the combination therapy was excellent in 17 cases (23.0%), good in 24 (32.4%) and poor in 33 (44.6%). Total clinical efficacy rate was 55.4%. Clinical efficacy rate was 40% against septicemias, 51.2% against suspected septicemias and 57.9% against respiratory tract infections. Causative pathogens were isolated in only 21 cases (28.4%): Gram-positive bacteria in 9 cases, Gram-negative bacteria in 11 and fungus in 1. About half of the Gram-negative bacteria belonged to Pseudomonas sp. The efficacy rate of this combination therapy against Gram-negative bacterial infections was 72.7% but the rate against Gram-positive bacterial infections were only 33.3%. Only in 1 case, this combination therapy was discontinued because of drug eruption. Abnormal laboratory findings were observed in 5 cases: Elevation of BUN in 3, GOT and GPT in 1 and prolongation of activated partial thromboplastin time in 1. In conclusion, this combination therapy of CMX and CFS is useful and safe against infections complicated by hematological disorders.

A Phase II study of recombinant leukocyte A interferon (rIFN-alpha A, Ro 22-8181) was performed in 121 patients with hematological malignancies at 33 institutions from July, 1982 to May, 1984. Patients received Ro 22-8181 by intramuscular injection daily for more than 4 weeks. Daily doses were escalated from 3 X 10(6) to 6X, 9X, 18X, 36X and 50X 10(6) units every 3-7 days. Among 70 evaluable cases, complete or partial responses were observed in 15 patients (21.4%). One complete and 10 partial responses (22.4%) were noted in 49 cases of multiple myeloma, 2 partial remissions (18.2%) in 11 cases of malignant lymphoma and 2 partial remissions (25.0%) in 8 cases of leukemia. Side effects included fever (57.0%), anorexia (34.2%), nausea-vomiting (22.8%), malaise (19.0%), leukopenia (44.3%), thrombocytopenia (45.6%) and increase of GOT or GPT (26.6% or 22.8%). They were all not serious and disappeared quickly after the discontinuation of Ro 22-8181.

Seventy-five patients with severe infection accompanying hematologic disorder, including leukemia and malignant lymphoma, were treated with cefotaxime (CTX). CTX was administered by intravenous drip infusion at a daily dose ranging from 4 to 16 g for terms of 3 to 21 days. The total doses were ranged from 12 to 226 g. The results obtained were as follows: Clinical effects: Excellent in 20 cases, good in 21 cases, fair in 7 cases and poor in 27 cases. The efficacy rate was 54.7% (41/75). Clinical effectiveness on isolated organisms (27 cases): In single infection (21 cases), the efficacy rates were 80% for Gram-positive cocci, including S. aureus and 63.6% for Gram-negative bacilli other than P. aeruginosa. In mixed infection (6 cases), the rate was 50.0%. There were no significant differences in the efficacy rates for those patients who were grouped by the initial number of neutrophil (less than 100, 101--500 and over 501/mm3). There were no significant difference in the efficacy rates for those patients who were grouped by the initial number of lymphocyte (less than 500 and over 501/mm3). Side effects and abnormal laboratory findings: One case of skin rash and 2 cases of elevated GOT and GPT were observed. CTX was therefore considered as a clinically useful antibiotic for the severe infections even in neutropenic state in patients suffering from malignant hematological diseases.

It was clinically evaluated by double blind method whether co-enzyme Q10 has protective effects on hair loss caused by anthracycline antibiotics. Six cases of acute leukemia, 2 blastic crisis of CML and 11 malignant lymphoma were entered to this study. DCMP regimen for acute leukemia for VEPA for lymphoma were performed. Coenzyme Q10 (or placebo) of 120 mg/day was orally administered. The grade of hair loss was classified into five groups. Five cases were only given to DM and 3 cases receiving DM and CoQ10. ADM was 6 cases and 5 were combined with CoQ10. No significant diffehence in effect of CoQ10 administration rence was recognized between two groups statistically. Elevations of GOT and GPT were less frequent in the group receiving CoQ10.
